Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a veterinary drug granulator. Background Art

[0002] Veterinary drugs refer to substances (including medicinal feed additives) used to prevent, treat, diagnose animal diseases or purposefully regulate animal physiological functions. Granulation is the process of processing materials in powder, melt, aqueous solution, etc. into granules of a certain shape and size. In the field of veterinary drug processing, it is sometimes necessary to granulate the raw materials.

[0003] Rotary granulator is one of the commonly used equipment for veterinary drug granulation. The extrusion granulation device of the rotary granulator on the market is usually composed of a rotating shaft and a blade. The blade is fixedly connected to the rotating shaft. The rotating shaft drives the blade to rotate at high speed. The material is squeezed out from the mesh of the granulation net cylinder through the tip of the blade to form material strips and fall into the hopper for collection.

[0004] When veterinary drugs are granulated by a rotary granulator, if particles of different sizes need to be produced, granulation screens with different apertures need to be replaced. This process takes a certain amount of time, resulting in interruption of equipment operation. Based on this, a veterinary drug granulator is provided. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 In the embodiment of the utility model, a veterinary drug granulator includes a rotary granulator 1 composed of a main box 101, a driving box 102, a lower hopper 103, a press knife 104, and a grinding knife 105. The driving box 102 and the lower hopper 103 are fixed to one end of the main box 101, and the lower hopper 103 is distributed on the outside of the driving box 102. The press knife 104 and the grinding knife 105 are distributed above the driving box 102 and extend to the inside of the driving box 102 through a connecting shaft and are transmission-connected to the output end of the driving structure inside the driving box 102. The grinding knife 105 is located at the top of the press knife 104, and the top of the driving box 102 is located on the outside of the press knife 104 and the grinding knife 105. A granulating component 2 is provided, and the granulating component 2 includes a granulating unit and an adjusting unit. The granulating unit is used to realize granulation of particles of different particle sizes, and the adjusting unit is used to realize adjustment and self-locking of the granulating unit.

[0026] The granulation unit includes a fixed net cylinder 201, a flange 202, and a rotating net cylinder 203;

[0027] The flanges 202 are symmetrically fixed to the upper and lower ends of the fixed net cylinder 201. The fixed net cylinder 201 is fixed to the driving box 102 through the bottom flange 202. The fixed net cylinder 201 is connected to the feed hopper 3 through the top flange 202.

[0028] The rotating net cylinder 203 is rotatably sleeved on the outside of the fixed net cylinder 201, and the granulation of particles of different sizes is achieved by changing the degree of misalignment between the mesh holes on the rotating net cylinder 203 and the mesh holes on the fixed net cylinder 201;

[0029] The adjustment unit includes a sector worm gear 204, an inverted L-shaped bracket 205, and a worm 206;

[0030] The fan-shaped worm gear 204 is fixed to the outer side of the rotating net cylinder 203 near the top. Two inverted L-shaped brackets 205 are provided. The two inverted L-shaped brackets 205 are symmetrically fixed to the outer side of the top flange 202. The worm 206 is rotatably connected to the middle of the two inverted L-shaped brackets 205 and meshes with the fan-shaped worm gear 204.

[0031] The worm 206 drives the rotating net cylinder 203 to rotate to achieve the misalignment adjustment of the meshes of the rotating net cylinder 203 and the fixed net cylinder 201;

[0032] The mesh distribution tracks and the apertures on the fixed mesh cylinder 201 and the rotating mesh cylinder 203 are the same.

[0033] In this embodiment: it is necessary to add that: the connecting shaft of the material grinding knife 105 passes through the middle of the rotating shaft of the pressure knife 104, and the driving box 102 is provided with a driving structure for driving the pressure knife 104 and the material grinding knife 105 to rotate synchronously in opposite directions. Therefore, the structure is a prior art structure, and this solution does not involve improvement of the internal structure of the driving box 102, so the internal driving structure of the driving box 102 is not described in detail;

[0034] When the equipment is running, the material grinding knife 105 pushes the material downward, and the material pressing knife 104 presses the material out from the mesh gap between the fixed mesh cylinder 201 and the rotating mesh cylinder 203, thereby realizing the granulation operation of the material;

[0035] During this process, if you need to adjust the particle size of the discharged material, the operation steps are as follows:

[0036] The worm 206 is manually rotated, and the worm 206 drives the fan-shaped worm wheel 204 to rotate, and the fan-shaped worm wheel 204 drives the rotating net cylinder 203 to rotate. At this time, the degree of misalignment between the mesh holes on the rotating net cylinder 203 and the mesh holes on the fixed net cylinder 201 changes, that is, the size of the gap channel formed by the two mesh holes changes, and then the size of the discharged particles is adjusted;

[0037] After the adjustment is completed, the worm 206 can be loosened. The self-locking structure of the worm 206 and the fan-shaped worm wheel 204 can keep the rotating net cylinder 203 in a stable and motionless state.

[0038] Please refer to Figures 1 to 4 The positions of the fan-shaped worm wheel 204 , the inverted L-shaped bracket 205 , the worm 206 and the mounting holes on the flange 202 are staggered.

[0039] In this embodiment: this structure ensures that the sector worm gear 204 , the inverted L-shaped bracket 205 , and the worm 206 will not interfere with the connection and installation between the flange 202 and the feed hopper 3 .

[0040] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
