Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 4 This invention discloses a filtration and separation device for processing extracts of traditional Chinese medicine decoction pieces, comprising a separation tank 1, a filtration and separation mechanism 2 rotatably mounted inside the separation tank 1, the filtration and separation mechanism 2 being connected to the separation tank 1 via a rotary drive assembly 3, a drain pipe 4 fixedly mounted at the bottom of one side of the separation tank 1, a slag hopper 5 fixedly mounted at the middle of the bottom of the separation tank 1, a screw conveyor 6 fixedly mounted at the bottom of the slag hopper 5, a backwashing assembly 7 mounted on one side of the separation tank 1, and a rotary drive assembly 3 consisting of a drive motor 8, a drive gear 9, and an external gear ring 10. The drive motor 8 is fixedly connected to one side of the top of the separation tank 1, the drive gear 9 is fixedly connected to the output shaft of the drive motor 8, and the external gear ring 10 is fixedly connected to the filtration and separation mechanism 2 and the drive motor 10. Gear 9 meshes. The filtration and separation mechanism 2 consists of a feed sleeve 11, a filter screen 12, a discharge sleeve 13, a guide sleeve 14, a sealing piston 15, and a cylinder 16. The feed sleeve 11 is rotatably connected to the separation tank 1. The filter screen 12 is fixedly connected to the bottom end of the feed sleeve 11. The discharge sleeve 13 is fixedly connected to the bottom end of the filter screen 12. The guide sleeve 14 is fixedly connected to the outer surface of the discharge sleeve 13. The cylinder 16 is inserted into the slag discharge hopper 5 and fixedly connected to it. The sealing piston 15 is rotatably connected to the top end of the cylinder 16. The sealing piston 15 is inserted into the discharge sleeve 13 and slidably connected to it. A limiting sleeve 17 matching the guide sleeve 14 is fixedly provided at the bottom end inside the separation tank 1. A liquid collection chamber 24 is formed between the limiting sleeve 17 and the separation tank 1.

[0021] In use, the herbal extract to be separated is placed into the filter separation mechanism 2. The drive motor 8 and drive gear 9 drive the outer gear ring 10 to rotate, which in turn drives the feed sleeve 11 to rotate, thereby driving the filter screen 12 and the discharge sleeve 13 to rotate. At this time, the blocking piston 15 moves into the discharge sleeve 13, thus preventing the extract from being discharged from the bottom of the discharge sleeve 13. Since the blocking piston 15 is rotatably connected to the cylinder 16, it can rotate with the discharge sleeve 13. The separated extract enters the collection chamber 24 and is then discharged through the drain pipe 4. After separation, the cylinder 16 drives the blocking piston 15 to move down, and the blocking piston 15 separates from the discharge sleeve 13, so that the residue is discharged along the side of the blocking piston 15 into the slag hopper 5 and then discharged through the screw conveyor 6.

[0022] Depend on Figures 1 to 4 As shown, the feed sleeve 11 and the separator 1, and the discharge sleeve 13 and the limit sleeve 17 are rotatably connected by bearing 18. The sealing piston 15 has a conical structure and is rotatably connected to the cylinder 16 by bearing 19.

[0023] Bearing 18 and bearing 29 can improve the mobility of rotating parts connection. In actual use, bearing 18 and bearing 219 can be selected as tapered roller bearings, thrust bearings and other types of bearings as needed.

[0024] Depend on Figures 1 to 4 As shown, the backwashing assembly 7 consists of a water pump 20, a water suction pipe 21, a combined drain pipe 22, and several nozzles 23. The water suction pipe 21 is connected to the water inlet of the water pump 20. The combined drain pipe 22 is fixedly connected to one side inside the separator 1 and connected to the drain outlet of the water pump 20. The nozzles 23 are fixedly connected to the combined drain pipe 22 and located on the side of the filter screen 12.

[0025] During slag discharge, the water pump 20 is started simultaneously, and water is sprayed onto the outer side of the filter screen 12 through the combined drain pipe 22 and nozzle 23, thereby achieving backwashing and preventing slag from adhering to the inner surface of the filter screen 12 and being difficult to discharge.

[0026] In operation, by setting up a rotary drive assembly consisting of a drive motor, drive gear, and external gear ring, and a filtration and separation mechanism consisting of a feed sleeve, filter screen, discharge sleeve, guide sleeve, sealing piston, and cylinder, the centrifugal force generated by the rotational motion can be used to filter and separate the Chinese herbal extract, improving separation efficiency. The separated extract and residue can be discharged separately without disassembling the filter screen during discharge, improving the convenience and speed of the work. By setting up a backwashing assembly consisting of a water pump, water suction pipe, combined drainage pipe, and several nozzles, water can be used to backwash the filter screen when discharging residue, preventing residue from adhering to the inner surface of the filter screen and improving residue discharge efficiency.
