[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 5 This invention provides an embodiment of a traditional Chinese medicine powder filtration airflow rotary screen. The screen includes a filter body 1 and a discharge body 12 fixedly disposed below the filter body 1. The bottom of the filter body 1 is connected to the top of the discharge body 12. A first discharge pipe 14 is fixedly disposed at the bottom of the discharge body 12, and the first discharge pipe 14 is vertically disposed. A feed pipe 21 and a second discharge pipe 22 are fixedly disposed on the filter body 1, located on opposite sides of the filter body 1. A material tank 2 is fixedly disposed on the feed pipe 21. The filter body 1 is inclined, with the inclination direction from the feed pipe 21 towards the second discharge pipe 22. The discharge body 12 and the material tank 2 are fixedly disposed on a support, which is existing technology and is not shown in the figure.

[0023] Specifically, a rotating sieve 4 is installed inside the filter body 1. A screen for filtering Chinese medicine powder is fixed on the inner wall of the rotating sieve 4. The rotating sieve 4 is also inclined from the feed pipe 21 to the second discharge pipe 22. Qualified Chinese medicine powder (small particle powder) flows out through the screen from the first discharge pipe 14, while unqualified Chinese medicine powder (large particle powder) flows into the pulverizer through the second discharge pipe 22 for further pulverization.

[0024] Specifically, a first fixed plate 53 is fixedly installed on the side wall of the rotating screen 4 near the second discharge pipe 22, and a second fixed plate 54 is fixedly installed on the side wall of the rotating screen 4 near the feed pipe 21. A rotating shaft 7 is fixedly installed between the first fixed plate 53 and the second fixed plate 54. The first fixed plate 53 and the second fixed plate 54 are respectively fixedly installed on the inner walls of both sides of the filter body 1. A power assembly 3 is connected to one end of the rotating shaft 7 near the second discharge pipe 22.

[0025] Specifically, a power assembly 3 is provided on the filter body 1. The power assembly 3 includes a motor 32, a drive pulley 33, a driven pulley 34, and a belt 35. The motor 32 is fixedly installed on the top of the filter body 1. The drive pulley 33 is fixedly installed on the output shaft of the motor 32. The rotating shaft 7 passes through the rotating screen 4 on the side near the second discharge pipe 22. The driven pulley 34 is fixedly installed on the rotating shaft 7. The belt 35 is connected to the drive pulley 33 and the driven pulley 34 to form a belt drive. A protective plate 31 for protecting the power assembly 3 is fixedly installed on the filter body 1.

[0026] Specifically, since some of the mixed Chinese medicine powder entering the rotary sieve 4 is oily, this oily powder will adhere to the sieve mesh during the rotation of the rotary sieve 4, thus clogging the sieve mesh. Therefore, a first cleaning component 5 is provided inside the rotary sieve 4 to clean the powder adhering to the sieve mesh. The first cleaning component 5 includes a first connecting rod 52, a second connecting rod 55, a fixing rod, and a cleaning brush 51. The first connecting rod 52 is fixedly set on the outer ring of the first fixing plate 53, and the second connecting rod 55 is fixedly set on the outer ring of the second fixing plate 54. A fixing rod is fixedly set between the first connecting rod 52 and the second connecting rod 55, and the fixing rod connects the first connecting rod 52 and the second connecting rod 55. A cleaning brush 51 is fixedly set on the side of the fixing rod near the inner wall of the rotary sieve 4. The cleaning brush 51 adheres to the rotary sieve 4 to clean the sieve mesh. Furthermore, multiple sets of cleaning components are arranged along the circumference of the rotary sieve 4.

[0027] Specifically, while the cleaning brush 51 can scrape off some of the oily powder adhering to the screen, during the rotation of the rotating screen 4, the cleaning brush 51 will spread the oily powder on the screen, resulting in a large area of ​​oily powder on the screen. Therefore, a second cleaning component 6 is provided to reduce powder adhesion. The second cleaning component 6 includes an air plate 61 fixedly disposed between the filter body 1 and the rotating screen 4. The air plate 61 has an air passage 62 arranged along the axial direction of the rotating screen 4. The side of the air plate 61 near the rotating screen 4 has multiple air outlets 63. The inlets of the air outlets 63 are connected to the air passages 62. The inlets of the air passages 62 are connected to an air inlet pipe 64, and the other end of the air pipe is connected to an air pump.

[0028] Understandably, the air pump pumps gas into the air plate 61 through the air pipe, and the gas flows along the air passage 62 and is blown from the air outlet 63 onto the screen on the rotating screen 4, thereby blowing off the powder adhering to the screen.

[0029] Specifically, the filter body 1 includes an openable door panel 11, with a latch 13 at the bottom of the door panel 11. Opening the latch 13 allows for screen replacement, while closing the latch 13 prevents powder from flying out of the filter body 1. The latch 13 includes a first fixing plate fixedly mounted on the door panel 11 and a second fixing plate fixedly mounted on the discharge body 12. A vertical locking plate is fixedly mounted on the second fixing plate, and a flat locking plate is hinged to the first fixing plate. The flat locking plate has through holes, and the vertical locking plate passes through the through holes and is secured by a lock head.

[0030] Working principle: First, start the motor 32, which drives the rotating shaft 7 to rotate via belt drive. This, in turn, drives the first fixed plate 53 and the second fixed plate 54, which are fixed to the rotating shaft 7, to rotate, thereby causing the rotating sieve 4 to rotate. Then, the Chinese medicine powder in the material tank 2 is loaded into the rotating sieve 4 through the feed pipe 21. During the rotation of the rotating sieve 4, qualified powder flows out through the first discharge pipe 14 under the action of centrifugal force, while unqualified powder flows out through the second discharge pipe 22. During the rotation of the rotating sieve 4, some oily powder will adhere to the screen. The cleaning brush 51 can scrape off some of the powder adhering to the screen. At the same time, the air pump pumps gas into the air plate 61 through the air pipe. The gas is blown out from the air outlet 63, causing the powder adhering to the screen to fall off. The fallen powder flows out through the second discharge pipe 22.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
