Description

Technical Field

[0001] The utility model relates to the technical field of composite premix processing, in particular to a grading grinding device for composite premix processing. Background Art

[0002] Composite premixes are a uniform mixture of any two or more components of trace elements, vitamins, amino acids and non-nutritional additives and carriers or diluents in a certain proportion. In the current composite premix processing, after the material mixing is completed, the mixed material needs to be added to the grinding device for grinding treatment, so as to reduce the particle diameter of the composite premix and improve the finished product effect of the composite premix after mixing.

[0003] However, the grinding device currently used in composite premix processing has the following shortcomings in actual use: the grinding device mainly drives the material to rotate and contact the grinding disk through the rotating grinding roller to realize the material crushing and grinding operation. The ground material will be discharged from the grinding device through the discharge pipe under the action of gravity. During the entire grinding process, the material can only be ground once. The material after a single grinding is prone to uneven particles. In order to reduce the problem of uneven particles, the operator is often required to pour the material after preliminary grinding into the grinding device for re-grinding, which increases the workload and difficulty of the composite premix grinding operation.

[0004] In view of this, it is particularly important to design and manufacture a grinding device that can perform multi-stage grinding of materials and reduce uneven material particles in the processing of composite premixes. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the traditional grinding device for composite premix processing can only perform single-stage grinding on the material, which easily leads to uneven particles of the crushed and ground material, and to propose a graded grinding device for composite premix processing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A graded grinding device for processing composite premixes comprises a grinding jar, a discharge pipe connected to the middle part of the lower end of the grinding jar, a ground support frame fixed to the lower end of the grinding jar, a grinding disc installed at the inner bottom of the grinding jar, a jar cover installed at the upper end of the grinding jar, a first drive motor installed at the middle part of the upper end of the jar cover, a transmission shaft installed at the lower end of the first drive motor, a grinding roller installed at the lower end of the transmission shaft and corresponding to the grinding disc, and a feeding hopper installed at the right side of the upper end of the jar cover, wherein a coarse grinding mechanism for preliminary grinding of materials during feeding is arranged between the right end of the grinding jar and the lower end of the feeding hopper.

[0008] As a further description of the above technical solution:

[0009] The rough grinding mechanism includes an internal tooth grinding cylinder installed on the inner side of the right end of the grinding jar and located at the lower end of the feed hopper, a second drive motor installed on the outer side of the right end of the grinding jar and coaxial with the internal tooth grinding cylinder, and a spiral feeding blade installed on the left end of the second drive motor and located on the inner side of the internal tooth grinding cylinder.

[0010] As a further description of the above technical solution:

[0011] A connecting pipe penetrating the internal gear grinding cylinder is fixedly connected to the lower end of the feed hopper, and a feed inlet for the connecting pipe to be connected is provided on the right side of the upper end of the internal gear grinding cylinder.

[0012] As a further description of the above technical solution:

[0013] A plurality of grinding strips with a rotation direction opposite to that of the spiral feeding blades are fixed at equal angles on the inner wall of the internal gear grinding cylinder, and the spiral feeding blades and the internal gear grinding cylinder are in transitional fit.

[0014] As a further description of the above technical solution:

[0015] The inner side of the grinding jar is provided with a material mixing portion for evenly dispersing the material during the material feeding process.

[0016] As a further description of the above technical solution:

[0017] The material leveling part includes a screen arranged between the grinding jar and the middle part of the transmission shaft and having an outer diameter smaller than the inner diameter of the grinding jar, a plurality of support blocks fixed at equal angles between the screen and the grinding jar, and a plurality of material leveling scrapers fixed at equal angles on the outside of the transmission shaft and fitting with the upper end surface of the screen.

[0018] As a further description of the above technical solution:

[0019] An electric control box is installed at the front end of the grinding jar, and the output of the electric control box is electrically connected to the input end of the first drive motor and the input end of the second drive motor respectively.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the utility model, the original grinding device is scientifically and rationally improved, an internal tooth grinding cylinder, a second driving motor and a spiral feeding blade are arranged on the grinding tank, and a connecting pipe is arranged on the feed hopper. The material in the feed hopper can enter the right end of the internal tooth grinding cylinder through the connecting pipe. When the second driving motor is working, it can drive the spiral feeding blade to rotate, push the material in the internal tooth grinding cylinder from right to left, and continuously rub the grinding strips on the inner wall of the internal tooth grinding cylinder during the pushing process to perform primary grinding processing on the material. This structure can perform preliminary spiral grinding processing on the material in the feeding process, and then cooperate with the original grinding part to perform multi-stage grinding processing on the material, effectively reducing the occurrence of uneven particle problems after material grinding, thereby improving the quality of the finished product after the composite premix is ​​ground.

[0022] 2. In the utility model, a screen is arranged in the original grinding tank, and a material-leveling scraper is arranged on the transmission shaft. The material ground by the internal tooth grinding cylinder will move to the middle of the screen under the action of gravity. The material-leveling scraper rotating on the transmission shaft can rotate the material accumulated in the middle of the screen outward for scraping. The material that meets the particle diameter will pass through the screen and fall to the bottom of the grinding tank, while the material that cannot pass through the screen will move to the outer edge of the screen and fall to the bottom of the grinding tank. This structure can evenly screen and level the material in the feeding process, reduce the occurrence of material accumulation problems during the material grinding process, and at the same time, the material can be crushed in the second step during the leveling process, thereby further improving the grinding effect of the grinding device.

[0030] Specifically, Figure 1-3 As shown, the coarse grinding mechanism includes an internal tooth grinding cylinder 4 installed on the inner side of the right end of the grinding jar 1 and located at the lower end of the feed hopper 201, a second drive motor 5 installed on the outer side of the right end of the grinding jar 1 and coaxial with the internal tooth grinding cylinder 4, and a spiral feeding blade 501 installed on the left end of the second drive motor 5 and located on the inner side of the internal tooth grinding cylinder 4. At the same time, a plurality of grinding strips with a rotation direction opposite to that of the spiral feeding blade 501 are fixed at equal angles on the inner wall of the internal tooth grinding cylinder 4. The spiral feeding blade 501 is in transitional cooperation with the internal tooth grinding cylinder 4, so that during the rotation of the spiral feeding blade 501, the material in the internal tooth grinding cylinder 4 can be stably crushed and ground during the feeding process.

[0031] Among them, a connecting pipe 202 that penetrates the internal gear grinding cylinder 4 is fixedly connected to the lower end of the feed hopper 201, and an inlet 401 for the connecting pipe 202 to access is opened on the right side of the upper end of the internal gear grinding cylinder 4. After the connecting pipe 202 is inserted into the inlet 401, the material pipeline between the feed hopper 201 and the internal gear grinding cylinder 4 can be connected.

[0032] Specifically, Figure 2 and Figure 3As shown, a material mixing section for uniformly dispersing the material during the feeding process is provided on the inner side of the grinding jar 1, and the material mixing section includes a screen 6 which is arranged between the grinding jar 1 and the middle part of the transmission shaft 301 and has an outer diameter smaller than the inner diameter of the grinding jar 1, a plurality of support blocks 601 fixed at equal angles between the screen 6 and the grinding jar 1, and a plurality of material mixing scrapers 303 fixed at equal angles on the outer side of the transmission shaft 301 and in contact with the upper end surface of the screen 6.
