As the key equipment of producing commodity mortar, the research and development of mixer and application are subjected to the attention of industry always.At present, provide the multiple mixer that commodity mortar is produced that can be used for, comprise vertical or horizontal, twin axle or single axle, continous way or step mixer.Application shows that existing mixer roughly can satisfy the production needs of commodity mortar.But, for can be economical, produce high-quality commodity mortar efficiently, the mixed performance of mixer and reliability still have the requirement of further raising.For example, expectation is by furtheing investigate and be optimized and improve by the structure to agitating device the aspects such as relation of material movement state and mixed effect in the mixer, mixer is further improved, so that high performance mixer to be provided at aspects such as mixture homogeneity, mixing efficiencies.

Summary of the invention

The purpose of this utility model provides a kind of horizontal mixer improved agitating device, high mixed performance that has.

For this reason, the horizontal mixer that the utility model provides with improved agitating device, comprise horizontal cylinder, vertically pass described cylinder and rotatably mounted shaft, be arranged on a plurality of agitating units on the described shaft, it is characterized in that: each described agitating unit includes the upright mixing arm that is connected on the described shaft, be arranged on first stirring vane of described mixing arm end and be vertically set on the middle part of described mixing arm and second stirring vane that stretches out towards the direction of described first stirring vane dorsad.

Best, a plurality of described mixing arms are along the axially spaced-apart setting of described shaft and depart from certain angle formation helical arrangement in a circumferential direction successively.

Best, described mixing arm radially is vertically connected on the described shaft and two adjacent described mixing arms form the angles of 60,90 or 120 degree on the circumferencial direction of described shaft along described shaft.

Best, described first stirring vane is the ploughshare blade, and spends angles with the axial formation 30～35 of described mixing arm.

Best, axial formation 50～55 degree angles of described first stirring vane and described shaft.

Best, axial formation 30～45 degree angles of described second stirring vane and described shaft.

Best, described second stirring vane has extending axially and the Special-Shaped Surface of torsional bending along described mixing arm.

Best, the torsion angle of the described second stirring vane Special-Shaped Surface is 10～15 degree.

The horizontal mixer with improved agitating device that the utility model provides is compared with existing mixer, has following beneficial effect: by the reasonable Arrangement of mixing arm and first, second stirring vane, can make the material that is stirred form motions such as violent convection current, shearing, diffusion mixes, produce three-dimensional mixing effect, make material finish high-quality even mixing at short notice.This horizontal mixer has high production efficiency, big production capacity and good mixing performance, can guarantee that the mixed effect of material reaches best, is specially adapted to produce expeditiously high-quality commodity mortar.

Below, by embodiment the utility model is described in further detail.

The specific embodiment

The utility model provides a kind of horizontal mixer with improved agitating device, is specially adapted to produce expeditiously the high-quality commodity mortar.Its structure comprises referring to figs. 1 through shown in Figure 6:

Horizontal cylinder 2 is horizontal fixed and is bearing on the frame 1.Cylinder 2 inner formation are held the chamber that is stirred material, have not shown dog-house, discharge port on the barrel of cylinder 2, dog-house, discharge port place are provided with not shown feeding door, Dump gate respectively, feeding door, Dump gate be respectively by not shown switching mechanism control and open and close, and feeds intake to finish, the discharging operation.

Shaft 3 passes cylinder 2 vertically, and its two ends are by on two perpendicular end surface of the rotatably mounted cylinder 2 of bearing portion, and an end extends to outside the frame.

A plurality of agitating units are arranged on the shaft 3.

Drive unit (not shown) is arranged on a side of frame 1, and connects an end that drives shaft 3.

Above-mentioned each agitating unit has:

Mixing arm 4 radially is vertically connected on the shaft 3 along described shaft 3.

First stirring vane 5 is the ploughshare blade, is connected mixing arm 4 ends and forms angle a with the axial B-B of mixing arm 4, and angle a is 30～35 degree preferably.

Second stirring vane 6 is the middle part that vertically is installed in mixing arm 4 and the vanelets that stretches out towards the direction of first stirring vane 5 dorsad.Second stirring vane 6 has along the axial B-B extension of mixing arm 4 and the Special-Shaped Surface of torsional bending, and the torsion angle b of Special-Shaped Surface is 10～15 degree preferably.

A plurality of mixing arms 4 of a plurality of agitating units are along the axially spaced-apart setting of shaft 3 and depart from certain angle formation helical arrangement in a circumferential direction successively.Two adjacent mixing arms 4 form angle c on the circumferencial direction of shaft 3, angle c is 60,90 or 120 degree preferably.Mixing arm 4 is installed in shaft 3 as follows: make the axial C-C of first stirring vane and shaft 3 form angle d, angle d is 50～55 degree preferably, make second stirring vane 6 and the axial C-C of shaft 3 form angle e, angle e is 30～45 degree preferably.

Because this layout of the mixing arm 3 and first stirring vane 5, second stirring vane 6, when shaft 3 drives rotation by drive unit, 5 main stirring actions of first stirring vane, 6 auxiliary stirring actions of second stirring vane, thereby making the material that is stirred form motions such as violent convection current, shearing, diffusion mixes, produce three-dimensional mixing effect, material can be finished high-quality even mixing at short notice.

More than combine embodiment the utility model is illustrated, but this does not constitute restriction of the present utility model, any modification of making under same design, variation and replacement also all belong to the scope of the utility model protection.
