Description

Technical Field

[0001] The utility model relates to the technical field of air flow pulverizers, in particular to an air flow pulverizer for gas-producing medicine raw materials. Background Art

[0002] During the preparation of gas-generating drug raw materials, some materials need to be crushed. The airflow pulverizer is an ultra-fine grinding device that uses jet airflow as power to cause material particles to impact, collide, and grind against each other in high-speed airflow and be crushed.

[0003] Patent application number 202222664226.4 discloses an air flow mill for raw material grinding, including a grinding shell, a powder selection barrel, an air distribution pipe and an air intake main pipe. The right end of the powder selection barrel is movably connected to the bearing seat, and an air distribution pipe is installed at the middle position of the top of the inner part of the grinding shell through a bracket. A plurality of nozzles arranged at equal intervals are welded to the lower end of the air distribution pipe, and an air intake main pipe is welded to the upper end of the air distribution pipe. Compared with the prior art, the utility model has the following beneficial effects: by horizontally installing the vertically installed powder selection barrel and using a bearing seat instead of the mounting plate, the material moves horizontally during discharging, and the impacted material will directly return to the inside of the grinding shell and can rise again for discharge, and it is not easy for material to accumulate at the upper end of the grinder.

[0004] The above technical solution uses a discharge pipe to discharge the raw materials from the powder selection barrel. However, since the air distribution pipe will blow the insufficiently filtered raw materials out of the discharge pipe during the process of adding air to the powder selection barrel, the screening effect of the crushed raw materials is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a gas-producing medicine raw material air flow pulverizer in view of the shortcomings of the prior art, which realizes the function of the pulverized gas-producing medicine raw material through the screening channels at both ends of the pulverizing box in conjunction with the first screen and the air transmission plate structure fixed at the bottom of the first screen, thereby solving the problem of poor screening effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas-generating drug raw material air flow pulverizer, comprising a pulverizing box and a screening channel fixed at both ends of the pulverizing box, the inner wall of the pulverizing box is fixed with a first screen with an arc-shaped structure, and a partition is fixed at an angle at the bottom end of the pulverizing box, wherein an air transmission plate is fixed at the bottom end of the inner wall of the pulverizing box, the hollow cavity of the screening channel is provided with a screening cavity, both ends of the screening cavity are provided with through grooves connected to the pulverizing box, the top of the pulverizing box is provided with a second screen embedded and fixed in the through groove, and an air pump is fixedly installed in the cavity at the bottom of the partition.

[0007] Preferably, a feeding portion is provided at the top of the crushing box, and a sealing cover is embedded and fixed at the top of the feeding portion.

[0008] Furthermore, a gas generating medicine raw material feed pipe is fixed at the center of the top surface of the sealing cover, and grip rods are fixed on both sides of the top surface of the sealing cover. The top of the gas generating medicine raw material feed pipe is threadedly plugged with a sealing plug.

[0009] Furthermore, a discharge chute is provided at the bottom end of the side wall of the crushing box, and sealing doors are rotatably installed on both sides of the inner wall of the discharge chute.

[0010] Furthermore, the sealing door abuts against the inner wall of the discharge chute, and a handle is fixed to the side wall of the sealing door.

[0011] Furthermore, a motor is fixedly mounted on the side wall of the crushing box, and a shaft of the motor extends into the crushing box and is mounted with a plurality of crushing knives.

[0012] Furthermore, the top of the partition is at the same horizontal position as the through slot, and filters are embedded in both ends of the partition.

[0013] Furthermore, an air delivery pipe is installed at the top of the air pump, and the air delivery pipe passes through the partition and is fixedly connected to the air delivery plate.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model has screening channels fixed at both ends of a crushing box, and a first screen fixed on the inner wall of the crushing box. After the motor is started, the raw material is crushed by a crushing knife. During the crushing process, the air pump discharges air from the air pipe through the air pipe and blows up the raw material accumulated on the first screen. A part of the crushed raw material is screened by the second screen and falls to the bottom of the crushing box along the screening cavity. The other part of the raw material passes through the first screen and is screened and falls, which is convenient for screening the crushed raw material. The air supply plate allows the raw material to float and fully contact with the crushing knife, thereby improving the screening effect of the raw material after crushing.

[0016] (2) The utility model provides filters on both sides of the top surface of the partition. When the air pump is started, air passes through the filters and is sucked in. The filters can block the screened raw materials. At the same time, the inclined filters reduce the possibility of blockage, thereby improving the air flow efficiency. At the same time, after unscrewing the sealing plug, it is convenient to put the gas-generating drug raw materials from the gas-generating drug raw material feed pipe into the crushing box.
