Transfer grinding furnace 100 of the sink bowl type food waste treatment apparatus according to an embodiment of the present invention is a front cover 120 mounted to one side opening of the hollow cylinder-shaped grinding cylinder 110, the grinding cylinder 110, And a rear cover 130 mounted on the other opening of the grinding barrel 110, and a grinding screw 140 rotatably fixed in the grinding barrel 110.

When the sink ball type food waste processing apparatus inputs the food waste containing water through the sink bowl, the food bowl itself processes powders of food waste through processes such as dehydration, crushing, transfer, and drying.

The sink ball (not shown) and the pulverization bin 110 may be detachably coupled by bolting, or the sink ball and the pulverization bin 110 may be integrally injection-molded, but preferably to be easily manufactured and replaced. It must be detachably coupled.

The grinding cylinder 110 preferably has a taper shape in which the cross-sectional area becomes wider from one side to the other side. The pulverization bin 110 is disposed to be inclined, and the other side having an opening having a wide cross section is configured to be positioned below. The grinding barrel has a comprehensive process such as conveying, stirring, and pulverizing therein.

In the above state, the inlet 112 is formed at the lower upper end of the crushing container 110 so that food waste introduced from the sink bowl is introduced. In addition, at the upper lower end of the pulverization bin 110, the food wastes passing through the interior of the pulverization bin 110 are discharged to the outside or the discharge port 114 protrudes to move to a drying furnace (not shown) for later drying. It is possible. The outer surface of the pulverization bin 110 is provided with a separate drying heater is preferably dried at the same time in the process of grinding, conveying.

Then, the lower lower end of the crushing container 110 is provided with a drain hole 116 of a predetermined size under the inlet 112. Sewage generated during the grinding process in the grinding barrel 110 is discharged through the drain 116. In order to discharge the wastewater, the drain 116 may be equipped with a separate strainer or a filter (not shown).

The front cover 120 mounted on the upper opening of the grinding barrel 110 has a fixing groove 123 having a predetermined thickness in the inner central portion thereof, and the grinding plate 122 in a circumferential form to the outside of the fixing groove 123. Is formed. The crushing plate 122 has a washing plate shape having a structure in which protrusions and grooves are repeated, thereby crushing by the interlocking process with the crushing screw 140.

A fastening hole 121 protrudes from the front surface of the front cover 120. Inside the fastening hole 121, a hole into which a coupling means such as a bolt may be inserted is formed, and the coupling means fixes the front cover 120 and the grinding barrel 110 through the fastening hole 121.

The rear cover 130 is mounted in the lower opening of the crushing container 110, the through hole 131 is formed in the center of the rear cover 130 is a structure that can be inserted into one end of the rotating shaft 141.

Hereinafter, the grinding screw 140 according to an embodiment of the present invention will be described with reference to FIGS. 5 and 6.

The grinding screw 140 includes a rotating shaft 141 mounted on both side ends of the grinding barrel 110 to be rotatably fastened, and conveying blades 142 and 143 extending in a spiral direction from an outer circumferential surface of the rotating shaft 141. The conveying blades 142 and 143 are extended so as not to interfere with the first blade 142 over some sections of the outer circumferential surface of the first blade 142 and the outer circumferential surface of the rotating shaft 141. It consists of two blades (143).

Here, one end of the rotary shaft 141 mounted on the upper part of the grinding cylinder 110 is called the bow portion 141a, and the other end of the rotary shaft 141 is called the stern portion 145. The bow portion 141a is rotatably installed in the fixing groove 123 of the front cover 120, and the stern portion 145 is inserted into the through hole 131 of the rear cover 130 to be rotatably supported. The fixing groove 123 and the through hole 131 is provided with a rolling device such as a bearing so that the rotation shaft 141 rotates smoothly.

The stern portion 145 of the rotating shaft 141 is formed with a connection groove 145a connected to a separate driving device (not shown), and the driving device provides a rotational force to the rotating shaft 141.

The first blade 142 extends in a spiral shape along a radial direction of the rotation shaft 141 from an outer circumferential surface of one side end of the rotation shaft 141 to surround the rotation shaft 141. Since the grinding barrel 110 has a form that becomes narrower toward the upper portion, the first blade 142 from the stern portion 145 to the bow portion 141a in order to be rotatable without interference in the interior of the grinding cylinder 110. Increasingly, the turning radius tends to be smaller.

In the blade forming process of the first blade 142, the pitch between the blades is generally constant, but in the present invention, the pitch may gradually decrease. The pitch may be defined as a distance in which the blade of the first blade 142 moves in the axial direction on the rotation shaft 141 while rotating the rotation shaft 141 by 360 degrees.

The second blade 143 is formed so as not to interfere with each other between the blades of the first blade 142 to the extent extending from the bow portion 141a of the rotary shaft 141 to just before the inlet 112. That is, since the interval between the blades is more closely contacted on the rotation shaft 141 by the formation of the second blade 143, it can be seen that the pitch interval is narrower than the state in which the first blade 142 was previously present (FIG. 6). Reference numeral 148).

Referring back to Figure 6, it is preferable that the blade is formed so that the line 146 connecting the outer ends of the conveying blades (142,143) can proceed in a straight line. When designing the conveying blades 142 and 143, the blade radii of the conveying blades 142 and 143 must be considered to have a sufficient tolerance so as to have a sufficient tolerance with the inner diameter of the grinding barrel 110.

3 and 4, a grinding rib 111 having a predetermined thickness is formed along an axial direction on an inner surface of the grinding barrel 110. The grinding rib 111 finely grinds the food introduced into a predetermined space generated at a time with the cutting blades formed at the outer ends of the transfer blades 142 and 143.

On the rotary shaft 141, the auxiliary protrusion 144 protrudes in a predetermined form near the end of the transfer blades 142 and 143. The auxiliary protrusion 144 serves to smoothly discharge the food waste in the grinding bin 110 to the discharge port 114 side when the grinding screw 140 rotates. The food waste introduced into the inlet 112 is pushed to the upper portion of the crusher 110 by the crushing screw 140 in the crusher 110 as the auxiliary projection 144 rotates as the outlet 114 Can be pushed out.

When a certain circumference is drawn on the rotating shaft 141 to include the auxiliary protrusion 144, food waste flows into the space on the circumference without the auxiliary protrusion 144 on the circumference, and thus the auxiliary protrusion (144) rotates as the rotating shaft 141 rotates. 144 is rotated by interlocking to push the food gathered in the vicinity of the discharge port 114 to the outside.

Hereinafter, the operation of the transfer pulverization furnace of the food waste treatment apparatus of the present invention will be described with reference to FIGS. 1 to 6.

First, food waste is input from the sink ball through the input hole 112a of the inlet 112 and the rotary shaft 141 receives the power from the external power unit to start the rotation. The input food waste falls freely to the lower end of the grinding screw 140 and starts to be transferred to the upper side by the first blade 142.

As shown in FIG. 6, the first portion 147 having only the first blade 142 is formed in a relatively large pitch and has a structure in which a large amount of food waste can be circulated with ease. In the process of rotation rather than conveying to the side, the weight is more focused on the dehydration portion of agitation and sewage.

The second portion 148, in which both the first blade 142 and the second blade 143 are formed, has a narrower pitch interval than the first portion 147, so that food waste is transported at a higher speed. In addition, the radius of rotation in the grinding barrel 110 is also reduced. That is, in the second portion 148, since the free space that can accommodate food waste is relatively smaller than the first portion 147, the emphasis is more on transporting than stirring.

The sewage of food dehydrated during the operation of both the first portion 147 and the second portion 148 is naturally discharged to the lower drain 116 by gravity.

The foods conveyed to the upper side of the pulverization bin 110 by the conveying blades 142 and 143 are pulverized once more by the interlocking action of the pulverizing plate 122 and the pulverizing screw 140 formed inside the front cover 120. And exit to the outlet 114. In the process, the auxiliary protrusion 144 helps the smooth discharge of food waste.

In one embodiment of the present invention, the transfer pulverization furnace 100 of the food waste processing apparatus is described as an example of being installed in the sink bowl in the sink, as shown in the accompanying drawings, which is an example for convenience of description. It is only. Therefore, the present invention is not necessarily limited to the one connected to the sink bowl, and may be applicable to any facility capable of collecting food waste.

While preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments. That is, those skilled in the art to which the present invention pertains can make many changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications are possible. Equivalents should be considered to be within the scope of the present invention.
