[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Please refer to Figures 1-3 A traditional Chinese medicine liquid extraction and filtration device includes an extraction barrel 1, which is fixed on an extraction support 2. A filter barrel 3 is fixed inside the extraction barrel 1, and a plurality of filter holes 4 are provided on the barrel wall of the filter barrel 3.

[0023] A first discharge device is provided at the bottom of the filter barrel 3, and a second discharge device is provided at the top. The first discharge device includes a first discharge cylinder 5, which is vertically and upwardly arranged at the bottom of the extraction barrel 1. Several first limiting grooves 6 are opened on the inner wall of the filter barrel 3. A first pusher plate 7 is slidably locked in the first limiting groove 6. The piston rod of the first discharge cylinder 5 is fixedly connected to the first pusher plate 7.

[0024] The second discharge device includes a discharge trough 8, with a first discharge pipe 9 and a second discharge pipe 10 respectively at both ends of the discharge trough 8. A second discharge cylinder 11 is horizontally arranged on the right side of the discharge trough 8. Several second limiting through slots 12 are opened inside the discharge trough 8. A second pusher plate 13 is slidably opened in the second limiting through slots 12. The piston rod of the second discharge cylinder 11 is fixedly connected to the second pusher plate 13.

[0025] In this embodiment, after the Chinese medicinal materials are extracted, the sealing cover plate 15 is removed, and the first discharge cylinder 5 is activated to move upward, pushing the dregs out of the filter barrel 3. During the pushing process, the second discharge cylinder 11 drives the second pusher plate 13 to move back and forth in the limiting groove, thereby pushing the dregs into the first discharge pipe 9 and the second discharge pipe 10, so as to realize the rapid discharge of the dregs from the filter barrel 3.

[0026] During the extraction process, since the Chinese medicinal materials are confined within the filter tank 3, the resulting residue also remains within the filter tank 3, while the active ingredients are extracted into the purified water.

[0027] Several limiting grooves 14 are provided at the bottom of the limiting channel, and a sealing cover plate 15 is provided at the top of the filter barrel 3. The sealing cover plate 15 can be limited and locked in the limiting grooves 14. Several pressing plates 16 are provided at the bottom of the second pusher plate 13, and the pressing plates 16 can abut against the sealing cover plate 15. During the extraction process, the second pusher plate 13 moves above the sealing cover plate 15 under the action of the second pusher cylinder. At this time, the pressing plates 16 abut against the sealing cover plate 15, thereby limiting the sealing cover plate 15.

[0028] In this embodiment, after extraction and filtration are completed, the first discharge cylinder 5 is activated to drive the first pusher plate 7 to move upward, pushing the dregs upward. The dregs are squeezed under the action of the first pusher plate 7 and the sealing cover plate 15, which can squeeze out the residual liquid in the dregs.

[0029] An extraction tank 1 is fitted inside a heating tank 17. A steam outlet 18 is provided at the bottom of the tank wall of the heating tank 17, and a steam inlet 19 is provided at the top of the tank wall. An exhaust pipe 20 is provided at the top of the extraction tank 1, and a steam pressure regulating valve 21 is provided on the exhaust pipe 20. A drain pipe 22 is provided at the bottom of the extraction tank 1, and a drain valve 23 is provided on the drain pipe 22.

[0030] In this embodiment, steam inlet 19 is connected to an external steam delivery pipe, and the steam delivery pipe is connected to a steam pump.

[0031] Working principle: A certain amount of Chinese medicinal materials are placed in the filter bucket 3, and then a certain amount of purified water is added to the filter bucket 3. The purified water flows into the extraction bucket 1 through the filter hole 4. High-temperature steam is injected into the heating bucket 17 through the steam inlet 19 and discharged through the steam outlet 18 to heat the purified water and Chinese medicinal materials in the extraction bucket 1. During the heating process, extraction is achieved.

[0032] During the extraction process, the effective cost of the traditional Chinese medicine is extracted and filtered into the extraction tank 1. After the extraction is completed, the first discharge cylinder 5 is started to drive the first pusher plate to move upward, pushing the residue upward. The residue is squeezed under the action of the first pusher plate 7 and the sealing cover plate 15. After squeezing, the first pusher plate 7 moves downward.

[0033] The second discharge cylinder 11 moves to the right, causing the pressure plate 16 to release its restriction on the sealing cover 15, removing the sealing cover 15, and restarting the first pusher plate 7 to move upward slowly. During its movement, the first discharge cylinder 5 drives the second pusher plate 13 to move back and forth in the limiting groove, thereby pushing the dregs into the first discharge pipe 9 and the second discharge pipe 10.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
