Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0027] A box-type extraction device includes: a tank 1, wherein a mixing chamber 2 and a clarification chamber 3 are disposed inside the tank 1; the mixing chamber 2 is cylindrical; a motor 4 is fixed to the outside of the mixing chamber 2; a worm gear 5 is rotatably connected inside the mixing chamber 2; the output end of the motor 4 is fixedly connected to the worm gear 5; a hollow rotating shaft 6 is disposed inside the tank 1; a first worm wheel 21 is fixed to the outside of the rotating shaft 6 and meshes with the worm gear 5; a stirring blade 7 is fixed to the outside of the rotating shaft 6; and an extension rod 8 is fixed to the outside of the rotating shaft 6, with a hollow [blade / insert component] at one end of the extension rod 8. The stirring rod 9 is a core component. An elastic filter screen 10 is fixed to the top of the inner cavity of the tank 1. A cleaning mechanism is provided inside the tank 1. The cleaning mechanism does not work when the liquid in the mixing chamber 2 is being stirred. The cleaning mechanism is used to clean the filter screen 10 and the mixing chamber 2. A feed inlet 36 is provided on one side of the top of the tank 1. The feed inlet 36 is used to inject the extracted material into the mixing chamber 2. The motor 4 starts and drives the worm gear 5 to rotate. Then, the first worm wheel 21 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the stirring blade 7 and the stirring rod 9 to rotate and stir the liquid in the mixing chamber 2.

[0028] Furthermore, the cleaning mechanism includes a support frame 12 fixed to the top of the tank 1, a first cylinder 13 fixed to the top of the support frame 12, a high-pressure nozzle 14 installed at the bottom of the first cylinder 13, an opening 15 provided at the top of the tank 1 to facilitate the entry of the high-pressure nozzle 14 into the tank 1 during cleaning, and two opposing hollow chambers 16 fixed to the top of the tank 1, the interior of the hollow chambers 16 being filled with gas.

[0029] Furthermore, the top of the trough 1 is rotatably connected to two opposing sealing plates 17, the hollow chamber 16 has a spring 18 fixed inside and a piston 19 slidably connected thereto, and the bottom of the sealing plate 17 is rotatably connected to a bent rod 20, one end of which is located inside the hollow chamber 16 and rotatably connected to the piston 19.

[0030] It should be noted that the first cylinder 13 lowers the high-pressure nozzle 14, and then the high-pressure nozzle 14 passes through the opening 15 and presses the sealing plate 17. The sealing plate 17 is used to block the opening 15 to prevent dust and other impurities from entering. After being pressed, the sealing plate 17 rotates, and then the bent rod 20 enters the interior of the hollow chamber 16 and moves the piston 19 in the hollow chamber 16 to compress the spring 18.

[0031] Next, the two hollow chambers 16 are connected by air pipes 37. The inside of the stirring rod 9 is provided with an air bladder 22 that expands rapidly after inflation. The inside of the stirring rod 9 is slidably connected to a first scraper 23. One end of the first scraper 23 is fixedly connected to the air bladder 22. The air pipe 37 passes through the rotating shaft 6 and the extension rod 8 to communicate with the air bladder 22. A sealing ring is provided on the outside of the first scraper 23. The sealing ring can prevent liquid in the mixing chamber 2 from entering the inside of the stirring rod 9 and damaging the air bladder 22. A slide rail 24 is fixedly provided on the top of the tank 1. A vertical rod 25 is slidably connected to the outside of the slide rail 24. A vertical groove 26 is provided through the vertical rod 25. A protrusion 27 is fixed on the outside of the bent rod 20 and the protrusion 27 passes through the vertical groove 26. A second scraper 38 is fixed on the bottom of the vertical rod 25. The bottom of the second scraper 38 contacts the top of the filter screen 10.

[0032] When the bent rod 20 moves, the protrusion 27 moves within the vertical groove 26. Then, the two vertical rods 25 move in opposite directions along the slide rail 24 and both move towards the center of the filter screen 10. The two vertical rods 25, along with the two second scrapers 38, move in opposite directions, and the impurities on the top of the filter screen 10 are scraped off by the opposite movement of the two second scrapers 38.

[0033] It can be concluded that the motor 4 is used as the power source to drive the first scraper 23 to rotate. A water pump is installed on the outside of the tank 1. The water pump draws water into the interior of the high-pressure nozzle 14 through the water pipe and sprays the water out from the high-pressure nozzle 14. The sprayed water rushes towards the filter screen 10, which is beneficial for cleaning the impurities scraped off the top of the filter screen 10. At the same time, the sprayed water will flow along the interior of the mixing chamber 2. When the first scraper 23 rotates, it scrapes off the impurities adhering to its inner wall to achieve cleaning. A waste outlet is provided at the bottom of the mixing chamber 2. The cleaned impurities flow out from the waste outlet along with the water.

[0034] In addition, the cleaning mechanism includes an anti-clogging unit that can prevent the filter holes of the filter screen 10 from becoming clogged. A vertical frame 31 is fixed to the bottom of the filter screen 10. A second cylinder 32 is installed at the bottom of the vertical frame 31. A groove 33 is provided at the bottom of the vertical frame 31. A second worm gear 34 is rotatably connected inside the groove 1. The second worm gear 34 meshes with the worm 5. A cam 35 is fixed to the outside of the second worm gear 34.

[0035] Specifically, when the worm 5 rotates, it drives the second worm wheel 34 and the cam 35 to rotate. The cam 35 rotates and enters the interior of the vertical frame 31. Then, the cam 35 contacts the output end of the second cylinder 32. Since the output end of the second cylinder 32 blocks the cam 35, the cam 35 rotates and causes the filter screen 10 to elastically descend. When the filter screen 10 descends to a certain extent, the output end of the second cylinder 32 retracts into the cylinder and opens the bottom of the vertical frame 31. At this time, the vertical frame 31 is no longer affected by the cam 35. Then, the filter screen 10 quickly and elastically resets. The rebound of the filter screen 10 ejects impurities from the mesh to prevent blockage.

[0036] Working principle: The material enters the mixing chamber 2 through the feed inlet 36. The filter screen 10 helps to filter out larger impurities in the material. The liquid then enters the bottom of the mixing chamber 2, while the impurities remain on top of the filter screen 10. The liquid level is always controlled below the filter screen 10. Then, the motor 4 starts, driving the worm gear 5 to rotate. This rotation, through the first worm wheel 21, drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the stirring blades 7 and stirring rod 9 to rotate, stirring the liquid in the mixing chamber 2. This stirring part is described in the comparative document and will not be described here. The cleaning mechanism does not operate while the liquid in the mixing chamber 2 is being stirred.

[0037] After use, the cleaning mechanism of mixing chamber 2 is activated to prevent the two injections of different liquids from reacting and affecting the extraction. Cleaning is performed to ensure continued use. The cleaning method is as follows: the first cylinder 13 lowers the high-pressure nozzle 14, which then passes through opening 15 and presses against the sealing plate 17. The sealing plate 17 seals the opening 15 to prevent dust and other impurities from entering. The sealing plate 17 rotates under pressure, causing the bent rod 20 to enter the hollow chamber 16 and move the piston 19 within it, compressing the spring 18. As the piston 19 moves, air in the hollow chamber 16 is forced into the air pipe 37, and then into the air bladder 22. The air bladder 22 inflates rapidly, causing the first scraper 23 to move from inside the stirring rod 9. The blade of the first scraper 23 then contacts the inner wall of mixing chamber 2, which is cylindrical.

[0038] At the same time, as the bent rod 20 moves, the protrusion 27 moves within the vertical groove 26. Then, the two vertical rods 25 move in opposite directions along the slide rail 24 and both move towards the center of the filter screen 10. The two vertical rods 25, along with the two second scrapers 38, move in opposite directions, and the impurities on the top of the filter screen 10 are scraped off by the opposite movement of the two second scrapers 38.

[0039] Powered by motor 4, the first scraper 23 rotates. A water pump is installed outside the tank 1, drawing water through a water pipe into the high-pressure nozzle 14 and spraying it out. The sprayed water hits the filter screen 10, effectively cleaning the impurities scraped off the top of the filter screen 10. Simultaneously, the sprayed water flows along the inside of the mixing chamber 2, scraping off impurities adhering to its inner wall as the first scraper 23 rotates. A waste outlet is provided at the bottom of the mixing chamber 2, allowing the cleaned impurities to flow out with the water. This operation facilitates the simultaneous cleaning of the filter screen 10 and the mixing chamber 2.

[0040] When cleaning is required, the output end of the second cylinder 32 extends into the interior of the groove 33 to seal the bottom of the vertical frame 31. However, during stirring, the bottom of the vertical frame 31 is open. The purpose of opening is to facilitate the passage of the cam 35 during stirring. The filter screen 10 is elastic. When the worm gear 5 rotates, it drives the second worm wheel 34 and the cam 35 to rotate. The cam 35 rotates into the interior of the vertical frame 31 and then contacts the output end of the second cylinder 32. Since the output end of the second cylinder 32 blocks the cam 35, the cam 35 will cause the filter screen 10 to elastically descend when it rotates. When the filter screen 10 descends to a certain extent, the output end of the second cylinder 32 retracts into the cylinder and opens the bottom of the vertical frame 31. At this time, the vertical frame 31 is no longer affected by the cam 35. Then the filter screen 10 quickly and elastically resets. The rebound of the filter screen 10 ejects impurities from the mesh to prevent clogging. This device integrates stirring, cleaning, and anti-clogging functions.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
