Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: This example aims to provide a crusher for producing water pills.

[0034] according to Figures 1 to 4 As shown, it includes a primary crushing device 3, an air flow crushing device 1 and an air-powder separation tank 5;

[0035] The primary crushing device 3 is provided with a mounting bracket 2 on the outside, and the primary crushing device 3 is fixedly connected to the mounting bracket 2 so that the primary crushing device 3 is stably placed above the airflow crushing device 1. The primary crushing device 3 is arranged above the airflow crushing device 1 and is connected to the airflow crushing device 1 through an airflow feed pipe 4. The airflow feed pipe 4 includes a feed port connected to the primary crushing device 3, a discharge port connected to the airflow crushing device 1, and an air inlet connected to the air supply device. The primary crushing device 3 also includes a vertically arranged crushing tank 301. The primary crushing device 3 is provided with a cover plate 30 3. The second driving device is arranged on the cover plate 303. The cover plate 303 is provided with a feeding funnel for feeding dry medicinal materials. The feeding funnel is connected to the interior of the crushing tank 301. The second driving device is selected from a motor in this embodiment. The crushing frame 304 is rotatably mounted on the cover plate 303. The crushing frame 304 is provided with a plurality of crushing cutters for crushing dry medicinal materials. The second driving device is used to drive the crushing frame 304 to rotate. The rotation of the crushing frame 304 makes the crushing cutters contact with the dry medicinal materials, so that the crushing cutters crush the dry medicinal materials. A feeding port is provided on the cover plate 303.

[0036] A sieve plate 302 is provided in the middle of the crushing tank 301, and the sieve plate 302 is located below the crushing frame 304. The sieve plate 302 divides the crushing tank 301 into an upper cavity and a lower cavity. The sieve plate 302 is provided with sieve holes. The medicinal material powder blocks produced after the dry medicinal materials are initially crushed can pass through the sieve holes and fall downward. The crushing frame 304 is located in the upper cavity.

[0037] The lower part of the crushing tank 301 is a funnel structure that is wide at the top and narrow at the bottom, and a discharge hole connected to the feed port of the air flow feed pipe 4 is opened at the bottom of the crushing tank 301.

[0038] The air flow pulverizing device 1 and the primary pulverizing device 3 are connected to the air flow pulverizing device 1 so that the medicinal material powder blocks crushed by the primary pulverizing device 3 enter the air flow pulverizing device 1. The air flow pulverizing device 1 includes a hollow cylindrical protective outer cover 101 and a flying disc 103 arranged in the protective outer cover 101. A friction plate 104 is fixed to the upper surface of the flying disc 103. The friction plate 104 is a diamond grinding disc in this embodiment. The surface of the diamond grinding disc is a friction particle surface. The medicinal material powder blocks contact the friction particle surface so that the medicinal material powder blocks are frictionally crushed. The center of the flying disc is located on the axis of the protective outer cover 101. A first driving device connected to the flying disc 103 is fixed to the bottom of the protective outer cover 101. The first driving device is a motor in this embodiment. The first driving device drives the flying disc 103 to rotate in the protective outer cover 101 to realize the mutual collision and friction between the medicinal material powder blocks to form medicinal material powder.

[0039] The gas-powder separation tank 5 is connected to the air flow pulverizing device 1. A negative pressure fan 503 is provided in the gas-powder separation tank 5 to suck the medicinal material powder in the protective outer cover 101. A discharge funnel is provided at the lower part of the gas-powder separation tank 5, and a collecting tank 8 is installed on the discharge funnel. An exhaust port is provided on the gas-powder separation tank 5, and a filter is provided in the exhaust port. The filter blocks the exhaust port near one side, and qualified medicinal material powder cannot pass through the filter. The negative pressure fan 503 is provided at the exhaust port, and a filter bag 6 is fixed on the exhaust port.

[0040] The protective outer cover 101 is circumferentially provided with a plurality of air nozzles connected to an air source. In this embodiment, the air source is a turbo blower, which can provide a relatively high air flow velocity. The blowing port of the air nozzle is arranged along the tangential direction of the inner wall of the protective outer cover 101 to drive the medicinal material powder to rotate in the protective outer cover 101 to form a vortex. The blowing port of the air nozzle is located above the flying disc 103.

[0041] The upper cover of the protective outer cover 101 is provided with a discharge pipe connection port 105, in which a feed pipe 7 connecting the air flow pulverizing device 1 and the air-powder separation tank 5 is installed. The discharge pipe connection port 105 is arranged on the axis of the protective outer cover 101. During the negative pressure suction process, the air outlet speed of the negative pressure fan 503 and the inner diameter of the pipe are adjusted so that the suction force generated can only inhale the medicinal material powder. The medicinal material powder blocks that are not completely crushed can overcome the suction force and remain in the protective outer cover 101, thereby separating the medicinal material powder and the medicinal material powder blocks. The air flow feed pipe 4 is a pipe section arranged obliquely from top to bottom and from right to left, and the air flow feed pipe 4 is connected to the air source.

[0042] Working principle: First, the medicinal materials are dried in the sun to become dry medicinal materials, and then the dry medicinal materials are sent to the inside of the crushing tank 301. Then, the crushing frame 304 is driven by the second driving device. When the crushing frame 304 rotates, the crushing cutter crushes the medicinal materials. The medicinal materials rub against each other, so that the medicinal materials are crushed into powder blocks, and the powder blocks pass through the sieve holes on the sieve plate 302 and fall down.

[0043] The fallen medicinal material powder blocks fall into the air flow feed pipe 4 , and the air flow feed pipe 4 is blown into a high-speed air flow through an air source. The high-speed air flow blows the powder blocks that fall into the air flow feed pipe 4 into the protective outer cover 101 .

[0044] The air nozzle 102 in the protective outer cover 101 and the air flow blown in by the air nozzle 102 and the air flow feed pipe 4 jointly generate a high-speed vortex, and the medicinal material powder block is drawn into the high-speed vortex to generate gas-solid rotational motion. At the same time, driven by the second driving device, the flying disc 103 rotates, and the rotation direction of the flying disc 103 is opposite to the rotation direction of the high-speed vortex. The medicinal material powder block and the friction plate 104, as well as the powder blocks, are squeezed, rubbed and collided with each other, thereby crushing the powder block into fine powder. At the same time, the fine powder is blown toward the center of the flying disc 103 driven by the high-speed vortex.

[0045] The negative pressure fan 503 in the gas-powder separation tank 5 generates negative pressure in the gas-powder separation tank 5. Under the action of the negative pressure, the gas-powder separation tank 5 sucks the fine medicinal powder at the center of the flying disc 103 into the tank body 501 through the feed pipe 7. At the same time, the negative pressure fan 503 sends the gas out of the tank body 501. The qualified medicinal powder in the gas cannot pass through the screen. At the same time, the filter bag 6 fixed at the air outlet end of the negative pressure fan 503 filters and collects the fine medicinal dust in the gas, thereby preventing the gas discharged from the equipment from polluting the air.

[0046] The medicinal material powder in the tank body 501 falls downward and eventually falls into the collecting tank 8 . After the crushing is completed, the medicinal material powder is collected by removing the collecting tank 8 .

[0047] In this way, the medicinal materials can be crushed into larger powder blocks through primary crushing. The larger powder blocks are then sent into the protective outer cover 101 for secondary crushing. The medicinal material powder blocks are crushed into fine medicinal material powder under the combined action of the swirl and the flying disc 103 whose rotating direction is opposite to the direction of the swirl airflow. The fine powder produced after crushing is concentrated to the center of the flying disc 103 under the action of the swirl, and then is sucked into the tank body 501 by the feed pipe 7. The gas and powder are then separated by the gas-powder separation tank 5, thereby making the crushing efficiency higher and reducing the particles contained in the powder.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description.
