Detailed Embodiments

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] This embodiment provides a pulverizing classifier, as Figures 1 to 4 shown, including:

[0038] A pulverizing body 10, the pulverizing body 10 includes a pulverizing cylinder 11, an air inlet mesh hole 12, and a first baffle 13. The first baffle 13 is fixedly arranged inside the pulverizing cylinder 11. The air inlet mesh hole 12 penetrates through the wall of the pulverizing cylinder 11. The aperture of the air inlet mesh hole 12 and the vertical straight line formed by the opening of the pulverizing cylinder 11 are smaller than the distance between the first baffle 13 and the opening of the pulverizing cylinder 11.

[0039] A feeding pipe 20, one end of the feeding pipe 20 is fixedly connected to the pulverizing cylinder 11. The hollow cavity of the feeding pipe 20 is communicated with the pulverizing cylinder 11. The other end of the feeding pipe 20 is detachably connected to a feeding mechanism 40. A feeding hopper 60 is fixedly arranged on the feeding pipe 20. The hollow cavity of the feeding hopper 60 is communicated with the hollow cavity of the feeding pipe 20. The distance between the central axis of the feeding pipe 20 and the central axis of the closest air inlet hole 12 is greater than the sum of the diameters of the feeding pipe 20 and the air inlet hole 12.

[0040] A material suction mechanism 30, the material suction mechanism 30 includes a conical material suction pipe 31, a second baffle 32, and a discharge hole 33. The second baffle 32 is fixedly arranged at the conical end of the conical material suction pipe 31. The circumferential surface of the second baffle 32 is in interference fit with the conical end of the conical suction pipe 31. A blower is arranged inside the circular pipe of the conical material suction pipe 31. There are multiple discharge holes 33, which are arranged on the second baffle 32.

[0041] A pulverizing mechanism 50, the pulverizing mechanism 50 is detachably arranged on the first baffle 13 and is used for pulverizing the medicine input into the pulverizing cylinder from the feeding pipe 20.

[0042] By providing an air intake mesh hole 12 on the crushing cylinder 11, and arranging the air intake mesh holes 12 in a circumferential array on the circumferential wall of the crushing cylinder 11, a blower (not shown in the figure) provided in the conical suction pipe 31 can generate wind power to draw gas into the crushing cylinder 11 from the air intake mesh hole 12, blowing up the crushed medicine. The medicine with a particle size meeting the requirements is sucked out by the blower through the discharge hole, and the medicine with a particle size not meeting the requirements will continue to be crushed by the crushing mechanism 50, solving the problem in the prior art that the gas introduced by the dust blower easily blows up the crushed medicine, resulting in difficulty in collecting the crushed medicine. It should be noted that in the above, there is a gap between the blower provided in the conical suction pipe 31 and the conical suction pipe 31, and the crushed medicine can be blown out of the conical suction pipe 31 from the gap;

[0043] By providing a discharge hole 33, the aperture size of the discharge hole 33 is set according to the particle size of the crushed medicine. Only the medicine with a particle size smaller than the aperture size of the discharge hole 33 can pass through the discharge hole 33, and the medicine with a larger particle size will continue to be crushed by the crushing blade 52 in the crushing mechanism 50, thus ensuring the consistency of the particle size of the medicine to be crushed and meeting the requirements.

[0044] In some embodiments,

[0045] There are multiple air intake mesh holes 12, which are arranged in a circumferential array on the crushing cylinder 11. This can make the gas entering the crushing cylinder 11 more uniform and the medicine heat dissipation more uniform.

[0046] In some embodiments,

[0047] The discharge holes 33 are uniformly arranged on the second baffle 32. The discharge holes 33 being uniformly arranged on the second baffle 32 can make the crushed medicine enter the conical suction pipe 31 more uniformly, thus maximizing the suction of the conical suction pipe 31.

[0048] In some embodiments,

[0049] The discharge holes 33 are arranged in a circumferential array on the second baffle 32. The discharge holes 33 being arranged in a circumferential array on the second baffle 32 can improve the suction efficiency of the conical suction pipe 31 as much as possible.

[0050] In some embodiments, as Figure 4 shown,

[0051] The feeding mechanism 40 includes a feeding motor 41 and a spiral feeding blade 42. The feeding motor 41 is detachably connected to one end of the feeding pipe 20, the spiral feeding blade 42 is fixedly arranged on the output shaft of the feeding motor 41, and the spiral feeding blade 42 is located directly below the feeding hopper 60, and the medicine in the feeding hopper 60 can fall onto the spiral feeding blade 42.

[0052] By setting the spiral feeding blade 42, the automatic feeding of coarse materials is realized, and the coarse materials can be quickly fed into the crushing cylinder 11.

[0053] In some embodiments, such as Figure 4 shown,

[0054] The length of the spiral feeding blade 42 is the same as the length of the feeding pipe 20. By setting the length of the spiral feeding blade 42 to be the same as the length of the feeding pipe 20, the feeding speed of the spiral feeding blade 42 can be increased, thereby improving the feeding efficiency.

[0055] In some embodiments,

[0056] One end of the spiral feeding blade 42 away from the feeding motor 41 is located between the feed hopper 60 and the crushing cylinder 11. By locating one end of the spiral feeding blade 42 away from the feeding motor 41 between the feed hopper 60 and the crushing cylinder 11, it can be ensured that the spiral feeding blade 42 can always convey the medicine.

[0057] In some embodiments, such as Figure 3 、 Figure 4 shown,

[0058] The crushing mechanism 50 includes a crushing motor 51 and a crushing blade 52. The crushing motor 51 is detachably connected to the first baffle 13, the crushing blade 52 is detachably connected to the output shaft of the crushing motor 51, the crushing blade 52 is located inside the crushing cylinder 11, and the distance between the side of the crushing blade 52 away from the crushing motor 51 and the central axis of the closest air intake mesh hole 12 is greater than the diameter of the air intake mesh hole 12. This setting is to ensure that the crushing blade 52 is always below the air intake mesh hole 12, so that when the crushing blade 52 crushes the medicine, the medicine with a larger particle size will not be blown away by the gas in the air intake mesh hole 12, resulting in low efficiency when the crushing blade 52 crushes the medicine. In this embodiment, a sealing treatment is performed between the output shaft of the crushing motor 51 and the first baffle 13. For example, a sealing bearing is provided between the output shaft and the first baffle 13 to ensure the sealing performance of the crushing cylinder 11.

[0059] In some embodiments,

[0060] The detachable connection method between the crushing motor 51 and the first baffle 13 is bolt connection; the detachable connection method between the feeding motor 41 and one end of the feeding pipe 20 is bolt connection. By means of bolt connection, the quick disassembly and installation of the feeding motor 41 and the crushing motor 51 can be realized.

[0061] In some embodiments, such as Figure 1 shown,

[0062] A support 70 is fixedly arranged at the bottom of the crushing cylinder 11. The support 70 is circular, and the diameter of the support 70 is larger than the diameter of the crushing cylinder 11. By arranging the support 70, the stability of the crushing cylinder 11 can be ensured.

[0063] The working principle of the present utility model is as follows:

[0064] Start the crushing motor 51, the feeding motor 41, and the blower. Feed the medicine from the feeding hopper 60. The medicine is conveyed to the inside of the crushing cylinder 11 by the spiral feeding blade 42, crushed by the crushing blade 52. The crushed medicine is blown up by the gas entering the crushing cylinder 11 from the air inlet mesh holes 12, and is sucked out by the blower through the discharge holes 33 for collection.
