Problems solved by technology

[0004] Although jet milling equipment has been generally put into use at present, there are still some problems. For example, during processing, the crushing degree of materials is different, and the coarse and fine particles are not easy to separate, resulting in the quality of the finished product cannot be guaranteed. Some jet milling equipment is equipped with a classification area. The crushed materials move to the classification area with the updraft under the action of the fan suction, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classifying turbine, which increases the cost and requires frequent maintenance of the equipment Guaranteed air tightness

Embodiment 1

[0020] see Figure 1-3 , a self-selected drug processing and crushing device, including a main box body 1, a coarse crushing chamber 2 is provided inside the main box body 1, and a feeding port opened on the top surface of the coarse crushing chamber 2 and the top surface of the main box body 1 11 is connected, and the coarse crushing chamber 2 is used to preliminarily crush the pharmaceutical raw materials entering the main box 1 through the feed port 11. The main box 1 is also provided with an airflow crushing chamber 3, and the airflow crushing chamber 3 is located in the coarse crushing chamber. The bottom of the chamber 2 is connected through the rotary connecting pipe 13. The connection between the rotary connecting pipe 13 and the coarse crushing chamber 2 is located at the bottom of the coarse crushing chamber 2, and the connection between the rotary connecting pipe 13 and the airflow crushing chamber 3 is located on the side of the airflow crushing chamber 3. The rota...

Embodiment 2

[0024] The difference from Example 1 is that in order to ensure that raw materials can be coarsely crushed more quickly and evenly, the coarse crushing chamber 2 includes an integrally formed equalizing part 21 and a crushing part 22, and the rotating shaft 24 is located at the crushing part 22 Inside, the equalizing part 21 is in the shape of opening up, and there are multiple striking rods 23 in the equalizing part 21. The multiple striking rods 23 are distributed in a conical shape. When the raw material enters, it will collide with the multiple striking rods 23. Irregular impacts make the raw materials evenly divided when they reach the pulverizing part 22, thereby speeding up the efficiency of coarse pulverization.

Abstract

The invention discloses an optional type medicine processing crushing device. The optional type medicine processing crushing device comprises a main box body, the main box body is internally providedwith a rough crushing cavity, the top of the rough crushing cavity communicates with a feeding port formed in the top surface of the main box body, the main box body is further internally provided with an air flow crushing cavity, the air flow crushing cavity is located under the rough crushing cavity and communicates with the rough crushing cavity through a rotation connecting pipe, and the connecting position of the rotation connecting pipe and the rough crushing cavity is located at the bottom of the rough crushing cavity. According to the optional type medicine processing crushing device,the main box body is internally provided with the air flow crushing cavity with a plurality of sorting plates, in the air flow crushing process, crushing and powder collecting can be carried out through air flow generated by a strong-wind fan, automatic screening can be carried out through the sorting plates, the condition that raw materials which are not crushed completely are processed continuously is ensured, and the overall crushing quality of finished products is ensured; and the rotation connecting pipe is connected with the rough crushing cavity, shearing crushing is carried out beforeair flow crushing, and the air flow crushing efficiency is improved.

Description

technical field [0001] The invention relates to medical and chemical equipment, in particular to an optional medicine processing and crushing device. Background technique [0002] The main advantages of drug crushing are to increase the surface area of ​​drugs, promote drug dissolution, facilitate the preparation of formulated drugs, and facilitate dry storage, etc. Especially under the premise that most of the traditional Chinese medicine treatments use Chinese patent medicines, pharmaceutical companies basically cannot do without crushing for the processing of drugs. this processing step. [0003] At present, most processing enterprises still use conventional grinding equipment, and jet mills have gradually replaced conventional grinding equipment due to their processing advantages. Jet milling uses the self-grinding effect of materials to impact materials with high-speed airflow generated by compressed air. The materials have strong collision and friction with each other...
