In the first supporting block on first curved support plate and inclined-plane and the first arc screening plate in the first supporting block One rectangular mesh matches；The second supporting block on second curved support plate and the inclined-plane in the second supporting block and the second arc screening plate On the process that matches of the second rectangular mesh be：First, when the first arc screening plate and the second arc screening plate are not pressed down, first The first supporting block on curved support plate is in contact with the intrados that the first arc screening plate is not provided with the first rectangular mesh, the first leaf spring In compressive state；The second supporting block and the second arc screening plate on second curved support plate are not provided with the outer arc of the second rectangular mesh Face is in contact, and the second leaf spring is in compressive state.Second, in the process that the first arc screening plate and the second arc screening plate are pressed down In, the first supporting block with corresponding first rectangular mesh position is opposite on the first arc screening plate when, the first leaf spring reset make Under, the first supporting block on the first curved support plate is rapidly inserted into corresponding first rectangular mesh；The second supporting block with When corresponding second rectangular mesh position is opposite on second arc screening plate, under the reset response of the second leaf spring, the second curved support The second supporting block on plate is rapidly inserted into corresponding second rectangular mesh.Third, in the first arc screening plate and the second sieve bend During plate moves up reset, the wall surface of the first rectangular mesh on the first arc screening plate can squeeze the oblique of the first supporting block Face, then the first supporting block, under extruding force, the first supporting block drives the first curved support plate mobile to the first leaf spring direction, the One leaf spring is compressed, and detaches the first rectangular mesh until the first supporting block is extruded completely；Second party on second arc screening plate The wall surface of sieve pore can squeeze the inclined-plane of the second supporting block, then the second supporting block is under extruding force, the second supporting block drives the Two curved support plates are mobile to the second leaf spring direction, and the second leaf spring is compressed, detached until the second supporting block is extruded completely Second rectangular mesh.

The first arc sliding slot in the present invention can fully meet the first supporting block in the first curved support plate and stretch out first Arc sliding slot.Second arc sliding slot can fully meet the second supporting block in the second curved support plate and stretch out the second arc sliding Slot.

For the first expansion plate：First expansion plate stretches in the moving process of the first curved support plate, the first expansion plate Restriction effect is played to the motion track of the first curved support plate, prevents the shaking of the first curved support plate from causing the first support Block is difficult to enter in corresponding first rectangular mesh.For the second expansion plate：Movement of second expansion plate in the second curved support plate It stretches in the process, the second expansion plate plays restriction effect to the motion track of the second curved support plate, prevents the second arc branch The shaking of fagging causes the second supporting block to be difficult to enter in corresponding second rectangular mesh.

When vertical mill mill of the invention does not work, grinding roller combination is located at the upside of mill body, and in grinding roller combination Bushing is not contacted with the first arc screening plate and the generation of the second arc screening plate；First spring and second spring are uncompressed, the first arc Shape guide block is located at the top of the first arc guide barrel, and the second arc guide block is located at the top of the second arc guide barrel, the first arc screening plate The first sieve plate sliding channel is stretched out in one end far from arc shaped slider and the first rectangular mesh is located on annular liner disk upper disk surface, and second Arc screening plate stretches out the second sieve plate sliding channel far from one end of arc shaped slider and the second rectangular mesh is located at annular liner disk upper disk surface On.The first supporting block on first curved support plate connects with the intrados that the first arc screening plate is not provided with the first rectangular mesh Touching, the first leaf spring are in compressive state；The second supporting block and the second arc screening plate on second curved support plate are not provided with second The extrados of rectangular mesh is in contact, and the second leaf spring is in compressive state.

In the conical grinding roller course of work, male cone (strobilus masculinus) diameter of the conical grinding roller close to mill body middle position is less than circle For taper grinding roller close to the male cone (strobilus masculinus) diameter of the external disc of mill, it is inner cone that conical grinding roller, which is tapered end close to mill body middle position, End, conical grinding roller are rear tapered end close to the tapered end of the external disc of mill.It is, the male cone (strobilus masculinus) of tapered end is straight before conical grinding roller Diameter is less than the male cone (strobilus masculinus) diameter of tapered end after conical grinding roller.

When vertical mill mill pulverizing cement material of the invention, driving mechanism is acted and driving mechanism is through supporting wheel band Movable grinding disc body and annular liner disk rotation；Then, the material conveying mechanism on the upside of mill body falls cement material in mill body Middle position, the mill body then rotated drive cement material particle rotation, and cement material particle is under the action of the centrifugal force to mill Disc perimeter movement.Under the screening effect of the first arc screening plate and the second arc screening plate, large cement material particles are trapped in Between first arc screening plate and annular slot grinding inner headed face, medium cement material particle is trapped in the first arc screening plate and the second arc Between shape sieve plate, small cement material particle is trapped between the second arc screening plate and annular slot grinding periphery.

Later, pressing mechanism acts and pressing mechanism is moved down through the conical grinding roller of rotary column drive, and bushing follows circular cone Shape grinding roller moves down, and bushing can be with annular liner disk phase CONTACT WITH FRICTION, and bushing is by corresponding first arc screening plate and the second arc The shape sieve plate press position coplanar to annular liner disk.Since mill body drives the first arc screening plate and the rotation of the second arc screening plate, So bushing will squeeze the fillet of the first arc screening plate and the second arc screening plate, the first arc screening plate and the second arc screening plate quilt Extruding moves down, and the first arc screening plate and the second arc screening plate move down arc shaped slider, the first arc guide block and Two arc guide blocks follow arc shaped slider to move, and the first spring and second spring are compressed.When the first arc screening plate is pressed down against Afterwards, when one end end face of first arc screening plate far from arc shaped slider and annular liner disk upper disk surface reach co-planar；Second arc After sieve plate is pressed down against, one end end face of second arc screening plate far from arc shaped slider is coplanar up to also arriving with annular liner disk upper disk surface When state, arc shaped slider is moved down into the position being in contact with the kerve face of arc shaped slider sliding groove, arc shaped slider at this time It can not continue to move down.This ensures that bushing, during being milled with annular liner disk mutual extrusion, annular serves as a contrast The upper surface of disk forms the flat disk of a not no groove face, and the cement material in annular liner disk will not be extruded to annular lining In the second sieve plate sliding channel and the first sieve plate sliding channel of disk, it can more preferably cooperate with annular liner disk convenient for bushing and be milled.When After lower one group of bushing coining of the first arc screening plate and the second arc screening plate, the first arc screening plate and second be extruded before under Arc screening plate is just no longer influenced by the extruding of bushing, under the first spring and the reset response of second spring, the first arc guide block and Second arc guide block makes arc shaped slider movement reset to home position, and the first arc screening plate and the second arc screening plate move up Screening to home position, and the first arc screening plate and the second arc screening plate continues to screen cement material.

Bushing is after going down the first arc screening plate and the extruding of the second arc screening plate, bushing and liner disk mutual extrusion milling the The cement granules for being screened out at one arc screening plate and the second arc screening plate.Since conical grinding roller and bushing are all cone-shapeds State, and the male cone (strobilus masculinus) diameter of tapered end is less than the male cone (strobilus masculinus) diameter of tapered end after conical grinding roller before conical grinding roller, so being located at circle The bushing male cone (strobilus masculinus) diameter at taper grinding roller inner cone end is less than the male cone (strobilus masculinus) diameter that bushing end is bored after conical grinding roller.In bushing It is cooperated during being milled with annular liner disk, the front end portion extruding of bushing is trapped in the first arc screening plate and annular is ground The middle-end portion extrusion of large cement material particles between slot inner headed face, bushing is trapped in the first arc screening plate and the second arc Medium cement material particle between sieve plate, the rear end part extruding of bushing are trapped in outside the second arc screening plate and annular slot grinding Small cement material particle between disc.Such design can make bushing preferably squeeze milling variable grain size cement Material, bushing can be expressed to small cement material particle, medium cement material particle and large cement material particles simultaneously, to improve The efficiency of the cement material of broken different size particle；To in cement material shattering process, Particle Breakage produces conical grinding roller Raw vibration determines by Particle Breakage situation, because conical grinding roller is simultaneously to large, medium and small cement material forces particles, greatly Inhibition of the vibration generated after cement material Particle Breakage by small cement material Particle Breakage situation, thus conical grinding roller shake It is dynamic to be determined by the broken situation of small cement granules, and then the sound that conical grinding roller vibration generates can be with heat energy loss by small cement granules It is broken to determine.It is compared to cylindrical grinding roller milling cement material particle, cylindrical grinding roller milling needs first by large cement material Particle attrition crushing at medium cement material particle, then cylindrical grinding roller mill again by medium cement material particle attrition crushing at Small cement material particle, so cylindrical grinding roller vibration is crushed situation by large cement material particles substantially and determines, thus cylindrical The sound that grinding roller vibration generates can be crushed situation by large cement material particles substantially with heat energy loss and determine.Because of conical grinding roller shake The raw sound of movable property can determine that cylindrical grinding roller shakes the sound energy and heat energy loss generated with heat energy loss by small cement granules are broken Substantially situation is crushed by large cement material particles to determine, and small cement granules are broken so that the amplitude of grinding roller vibration is much smaller than flood Mud material particles are crushed the amplitude so that grinding roller vibration, so cooperate with the first arc screening plate and the design of the second arc screening plate The loss of conical grinding roller is less than the loss of cylindrical grinding roller.

During the first arc screening plate and the second arc screening plate are pressed down, in the first supporting block and the first arc screening plate When upper corresponding first rectangular mesh position is opposite, under the reset response of the first leaf spring, first on the first curved support plate Bracer is rapidly inserted into corresponding first rectangular mesh；In the second supporting block and the second rectangular mesh corresponding on the second arc screening plate When position is opposite, under the reset response of the second leaf spring, the second supporting block on the second curved support plate is rapidly inserted into accordingly The second rectangular mesh in.After the first arc screening plate is pressed down against, one end end face of first arc screening plate far from arc shaped slider When reaching co-planar with annular liner disk upper disk surface, the first supporting block can fit with the top wall surface of corresponding first rectangular mesh, Such first supporting block can play a supporting role to the first arc screening plate, avoid the first rectangular mesh by excessive lower pressure After be deformed.After the second arc screening plate is pressed down against, the second arc screening plate is far from one end end face of arc shaped slider and ring When shape liner disk upper disk surface reaches co-planar, the second supporting block can fit with the top wall surface of corresponding second rectangular mesh, in this way Second supporting block can play a supporting role to the second arc screening plate, and the second rectangular mesh is avoided to produce after by excessive lower pressure Change shape.The first curved support plate and dependency structure and the second curved support plate and dependency structure in the present invention be not in arc It is installed on the mill body of sliding block sliding groove upper end, avoids the mill body fluting installation in arc shaped slider sliding groove upper end in this way Strength reduction is caused after first curved support plate and dependency structure and the second curved support plate and dependency structure, keeps arc shaped slider sliding It is difficult to bear the powerful pushing from conical grinding roller after the mill body fluting of dynamic slot upper end.First curved support plate and related knot Structure is located at the mill body between the first sieve plate sliding groove and annular slot grinding inner headed face, and the second curved support plate and dependency structure are located at Mill body between second sieve plate sliding groove and annular slot grinding periphery, the intensity born after the mill body fluting of this position at two The obviously intensity than being born after the mill body fluting of arc shaped slider sliding groove upper end；So guaranteeing the first rectangular mesh and second party For sieve pore in the case where not being deformed after by excessive lower pressure, the first curved support plate and dependency structure are installed on first In mill body between sieve plate sliding groove and annular slot grinding inner headed face, the second curved support plate and dependency structure are installed on the second sieve The design in mill body between plate sliding groove and annular slot grinding periphery is more more excellent.

After the work of conical grinding roller stops, driving mechanism and pressing mechanism stop working, and mill body stops rotating, circular cone Shape grinding roller and bushing are returned to home position under pressing mechanism drive, and conical grinding roller and bushing no longer squeeze annular liner disk, First arc screening plate and the second arc screening plate are no longer influenced by the extruding of bushing.When the first arc screening plate and the second arc screening plate no longer After the extruding of bushing, under the first spring and the reset response of second spring, the first arc guide block and the second arc guide block So that arc shaped slider movement resets to home position, the first arc screening plate and the second arc screening plate are moved upwards up to home position. During the first arc screening plate and the second arc screening plate move up reset, the first rectangular mesh on the first arc screening plate Wall surface can squeeze the inclined-plane of the first supporting block, then the first supporting block, under extruding force, the first supporting block drives the first arc Support plate is mobile to the first leaf spring direction, and the first leaf spring is compressed, and detaches first party until the first supporting block is extruded completely Sieve pore；The wall surface of the second rectangular mesh on second arc screening plate can squeeze the inclined-plane of the second supporting block, then the second supporting block Under extruding force, the second supporting block drives the second curved support plate mobile to the second leaf spring direction, and the second leaf spring is compressed, until Second supporting block is extruded completely detaches the second rectangular mesh.
