[0036] The dust collecting structure includes an outer cylinder shell 4 whose top opening can be detachably connected to the output end of the negative pressure pipe 3, wherein the detachable connection method includes threaded connection and snap connection. The top opening of the outer cylinder shell 4 is also covered with an annular sealing gasket 5, such as Figure 2 As shown, when the outer cylinder shell 4 is connected to the output end of the negative pressure pipe 3, the gap between the end of the outer cylinder shell 4 and the output end of the negative pressure pipe 3 is sealed by the annular sealing gasket 5 to enhance the connection sealing performance of the dust collection structure;
[0037] The outer shell 4 has a mouth 9 formed inside. A sealing ring 10 is sleeved around the outer periphery of the mouth 9, and the mouth 9 is sealed and slidably connected to the inner cavity of the outer shell 4 via the sealing ring 10. A filter interception unit is provided at the bottom end of the mouth 9. Multiple transparent observation windows 6 are evenly distributed along the lower portion of the sidewall of the outer shell 4. The bottom end of the outer shell 4 is sealed and rotatably connected to an outlet pipe 7. The bottom ends of the multiple outlet pipes 7 are fixedly connected to the sidewall of the long negative pressure pipe 8.
[0038] Reference Figure 2 and Figure 3 , the embodiment of the present application provides a dust removal device for Chinese herbal medicine slices, the filter interception unit includes a filter cartridge 11 connected to the bottom end of the cartridge mouth 9;
[0039] A plurality of insulating bottom cylinders 12 are evenly arranged below the filter cartridge 11. An insulating guide rod 14 is slidably inserted into the top opening of the insulating bottom cylinder 12. A return spring 16 is sleeved on the outer periphery of the insulating guide rod 14 and connected between the bottom of the filter cartridge 11 and the top of the insulating bottom cylinder 12.
[0040] The top end of the insulating guide rod 14 is connected to the bottom of the filter cartridge 11, and the bottom end extends into the inner cavity of the insulating bottom cartridge 12;
[0041] A pair of switch terminals 15 are provided in the inner cavity of the insulating bottom cylinder 12. The upper switch terminal 15 is connected to the bottom end of the insulating guide rod 14, and the lower switch terminal 15 is connected to the bottom wall of the inner cavity of the insulating bottom cylinder 12.
[0042] An alarm light 13 with a battery installed inside is connected to the side wall of the insulating bottom cylinder 12;
[0043] The two switch terminals 15 are electrically connected to the alarm light 13, and when the two switch terminals 15 are in contact with each other, the alarm light 13 is triggered to turn on;
[0044] When the return spring 16 is in an initially relaxed state, the top of the tube mouth 9 fits against the top wall of the inner cavity of the outer tube shell 4 , and the bottom of the insulating bottom tube 12 fits against the bottom wall of the inner cavity of the outer tube shell 4 .
[0045] Working principle:
[0046] The end of the long negative pressure pipe 8 is connected to the suction nozzle of the external negative pressure vacuum pump, so that the air inside the negative pressure pipe 3 is continuously extracted and negative pressure is formed, and then the dried Chinese medicine slices to be screened are poured into the feed port of the linear vibrating screen 1.
[0047] The dust generated during the screening process of Chinese medicine slices is sucked into the negative pressure pipe 3 and then enters the dust collection structure. The dust in the air is intercepted and filtered by the filter cartridge core 11 arranged in the filter interception unit in the dust collection structure, and the filtered gas then enters the negative pressure long pipe 8 through the outlet pipe 7.
[0048] When the filter cartridge 11 in the filter interception unit is clogged due to excessive dust collection, the gas in the inner cavity of the outer cylinder shell 4 is continuously extracted through the outlet pipe 7, so that the air pressure in the inner cavity of the outer cylinder shell 4 gradually decreases, and the filter cartridge 11 moving toward the outlet pipe 7 drives the switch terminal 15 connected to the end of the insulating guide rod 14 to contact the switch terminal 15 connected to the bottom wall of the inner cavity of the insulating bottom cylinder 12, and triggers the alarm light 13 to turn on. The light generated by the alarm light 13 after it is turned on passes through the transparent observation window 6, which makes it convenient for the staff to discover the fault in time and deal with the blockage fault of the dust collection structure in time.
[0049] The present application enables the dust collecting structure provided on the output end of the negative pressure pipe 3 to capture and collect the dust generated when the dried Chinese medicine slices are screened by the linear vibrating screen 1 under negative pressure, and when the dust collecting structure is blocked due to excessive dust collection, the dust collecting structure can actively issue an alarm to the outside, so as to facilitate the staff to discover the fault in time and deal with the blockage of the dust collecting structure in time, so as to ensure the negative pressure capture effect of the dust collecting structure on the dust generated when the Chinese medicine slices are screened.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
