[0002] Chinese herbal medicine slices are Chinese herbal medicines that have been processed and prepared according to the theories and methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. Chinese herbal medicine slices include some Chinese herbal medicine slices processed at the place of origin, original herbal medicine slices, and slices that have been cut and roasted. In the production of Chinese herbal medicine slices, it is necessary to sort the slices of Chinese herbal medicine. The slices are sorted under the vibration of the vibrator in the sorting screen to distinguish the slices of different specifications.

[0003] A vibrating screen for sorting Chinese herbal medicine pieces is disclosed in Chinese patent application No. 202120849702.2. The patent places the pieces into a lower hopper, spreads the pieces in the lower hopper onto a sieve plate, and then enables the pieces on the sieve plate to be vibrated and screened under the vibration of an exciter. Some pieces of suitable size are discharged through a discharge pipe, while pieces of smaller size fall from the sieve plate into the collecting hopper below. However, in the above-mentioned process of vibrating and screening the pieces, the vibration will cause the dust on the surface of the pieces to float away. Although some dust in the screening box falls into the collecting hopper below, most of the dust floating in the screening box is still easy to adhere to the surface of the pieces during the dispersion, resulting in a lot of dust adhering to the surface of the pieces coming out of the discharge pipe, affecting the appearance cleanliness of the Chinese herbal medicine pieces and reducing the production and processing quality of the Chinese herbal medicine pieces. For this reason, we propose a sorting screen for the production of Chinese herbal medicine pieces. Utility Model Content

The top of the cylinder 200 is fixedly connected to a round cover 202 by a plurality of groups of bolts. A connecting hose 203 is fixedly arranged between the round cover 202 and the three-way pipe 204. Two groups of suction fans 201 are arranged outside the cylinder 200, and a filter element for dust filtration is arranged inside the cylinder 200.

[0023] A support frame 207 is fixedly arranged between the suction fan 201 and the top cover 100, and the suction fan 201 can generate suction force to transport dust into the cylinder 200;

[0024] The end of the connecting hose 203 passes through the interior of the round cover 202, and the dust collecting box 205, the three-way pipe 204, the connecting hose 203 and the cylinder 200 are connected;

[0025] The filter element includes a filter element 208 , which can filter dust entering the interior. The filter element 208 is disposed inside the cylinder 200 .

[0026] The utility model uses a designed dust collecting mechanism to collect dust scattered during the screening process of Chinese herbal medicines under the action of the sieve plate 103 inside the screening box 102, and then filters it through the filter element 208, thereby reducing the amount of dust scattered in the screening box 102 under the action of the vacuum and adhering to the Chinese herbal medicines, thereby improving the cleanliness of the Chinese herbal medicines and increasing the production and processing quality of the Chinese herbal medicines.

[0027] Example 2

[0028] Based on Example 1, please refer to Figure 4 and Figure 5 The top and bottom of the filter element 208 are fixedly provided with rubber sealing rings 300 , which can increase the sealing effect. The bottom of the inner wall of the cylinder 200 is fixedly provided with multiple groups of limiting columns 301 .

[0029] The utility model combines the designed rubber sealing ring 300 and the limiting column 301. During use, the rubber sealing ring 300 can increase the sealing performance between the top of the filter element 208 and the round cover 202, and between the bottom of the filter element 208 and the bottom of the inner wall of the cylinder 200, thereby increasing the filtering effect on dust and avoiding the probability of dust leakage between the top of the filter element 208 and the round cover 202, and between the bottom of the filter element 208 and the bottom of the inner wall of the cylinder 200.

[0030] In this embodiment, preferably, a discharge pipe 107 is fixedly provided on the side of the screening box 102 , and a valve 106 is fixedly provided on the bottom of the collecting hopper 104 .

[0031] The working principle and use process of this utility model:

[0032] When the utility model is in use, after the Chinese herbal medicine pieces enter the screening box 102 from the feed port 101, they are screened under the vibration of the sieve plate 103. In this process, a lot of dust will be generated and scattered in the screening box 102. At this time, the two sets of suction fans 201 are turned on. At this time, the suction fans 201 generate suction force to generate negative pressure inside the cylinder 200. At this time, the suction port 206 located at the bottom of the dust suction box 205 generates suction force to suck the dust in the screening box 102 into the dust suction box 205, and then enter the filter element 208 in the cylinder 200 through the three-way pipe 204 and the connecting hose 203. At this time, the air containing dust passes through the filter element 208, and the filter element 208 filters the dust. The clean air is discharged outward through the suction fan 201, and then the dust is collected and filtered.

[0033] The rubber sealing ring 300 can increase the sealing performance between the top of the filter element 208 and the round cover 202, and between the bottom of the filter element 208 and the bottom of the inner wall of the cylinder 200. In addition, during the process of installing the filter element 208 into the cylinder 200, it is limited by multiple sets of limiting columns 301 to prevent the filter element 208 from moving outward during use, thereby facilitating the disassembly and replacement of the filter element 208.
