Description

Technical Field

[0001] The utility model belongs to the technical field of feed additive production equipment and relates to an extrusion type solid-liquid mixture mixer. Background Art

[0002] The raw materials of feed additives are mixed uniformly using a mixer during the mixing process before fermentation. Since the solid materials in the raw materials are mainly plant tissue powder, they are easy to clump and sink to the bottom when mixed with water. Therefore, the eccentric stirring paddle mixer currently used has low mixing efficiency for sedimentation materials and does not have a good crushing effect on caking materials. Utility Model Content

[0003] The purpose of the present invention is to provide an extrusion type solid-liquid mixture mixer to address the above-mentioned problems existing in the existing technology. The technical problem to be solved by the present invention is how to improve the mixing efficiency.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an extrusion type solid-liquid mixture mixer, characterized in that it includes a barrel, a cover plate and a driving motor arranged on the cover plate, a stirring shaft is fixedly provided on the output shaft of the driving motor, the stirring shaft has a spiral lifting piece, a lifting sleeve is provided on the outer sleeve of the stirring shaft, and a coil spring is connected between the lifting sleeve and the cover plate; the barrel is provided with a feed pipe and a discharge pipe located at the upper and lower positions of the barrel respectively.

[0005] Furthermore, the lifting sleeve is in the shape of a cone with the large diameter end facing upward, and the lifting piece is adapted to the inner wall of the lifting sleeve.

[0006] Furthermore, the material barrel is a tapered barrel with the small diameter end facing downward.

[0007] This solution uses the rotation of the spiral lifting piece to suck the material at the bottom of the barrel from the bottom of the sleeve to the top of the sleeve, and uses the coil spring as a filter to squeeze the material out from the gap between adjacent circles of the coil spring. It can be seen that when a lot of material accumulates in the coil spring to form a large pressure, the coil spring stretches to increase the discharge pore. At the same time, the gap between the lifting piece and the sleeve can be increased to reduce the efficiency of material lifting. Therefore, the material is not easy to be blocked, especially the presence of agglomerated materials will not cause the stirring shaft to get stuck. In addition, when the material passes through the pores of the coil spring more smoothly, the efficiency of the material being sucked from the bottom to the top of the sleeve is also higher, and larger agglomerated materials can be refined during the extrusion process at the pores of the coil spring.

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 The extrusion-type solid-liquid mixture mixer shown includes a barrel 1, a cover plate 2 and a drive motor 3 arranged on the cover plate 2. A stirring shaft 4 is fixedly provided on the output shaft of the drive motor 3. The stirring shaft 4 has a spiral lifting piece 5. A lifting sleeve 6 is provided on the outer sleeve of the stirring shaft 4. A coil spring 7 is connected between the lifting sleeve 6 and the cover plate 2; the barrel 1 is provided with a feed pipe and a discharge pipe located at the upper and lower positions of the barrel 1 respectively.

[0012] The lifting sleeve 6 is in the shape of a cone with the large diameter end facing upward, and the lifting piece 5 is adapted to the inner wall of the lifting sleeve 6 .

[0013] Bucket 1 is a tapered bucket with its minor diameter end facing downwards, so that the sediment can be brought as close as possible to the lower end of lifting sleeve 6.

[0014] In this solution, the material at the bottom of the barrel 1 is sucked from the bottom of the sleeve 6 to the top of the sleeve 6 by the rotation of the spiral lifting piece 5, and the coil spring 7 is used as a filter to squeeze the material out from the gap between adjacent circles of the coil spring 7. It can be seen that when a large amount of material accumulates in the coil spring 7 to form a large pressure, the coil spring 7 is stretched to increase the discharge pore. At the same time, the gap between the lifting piece 5 and the sleeve 6 can be increased to reduce the efficiency of material lifting. Therefore, the material is not easy to be blocked, especially the presence of agglomerated materials will not cause the stirring shaft 4 to be stuck. In addition, when the material passes through the pores of the coil spring 7 more smoothly, the efficiency of the material being sucked from the bottom to the top of the sleeve 6 is also high, and the agglomerated materials of larger size can be refined during the extrusion process at the pores of the coil spring 7.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
