The surface of the guide hopper 302 is evenly provided with through holes for conveniently throwing out the crystals and the mother liquor. The unseparated crystals and the mother liquor are delivered to the inside of the guide hopper 302 through the feeding pipe 303. At the same time, the guide hopper 302 is powered on to drive the guide hopper 302 to rotate through the shaft. The rotating guide hopper 302 throws out the unseparated crystals and the mother liquor inside through the through holes. The thrown out crystals are evenly attached to the inner wall of the rotating filtering drum 5. A limiting groove 202 is provided on the lower side of the inner wall of the separation tank 2.

[0023] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the scraper mechanism 6 includes an electric push rod 601, which is installed on the top of the sealing cover 201 through a mounting plate, and a mounting seat 602 extending to the inside of the separation tank 2 is fixedly installed on the bottom of the electric push rod 601, and mounting blocks 603 are fixedly installed equidistantly on the outside of the mounting seat 602. The operator controls the electric push rod 601 to operate through the controller 10, and the powered electric push rod 601 drives the scraper 605 to move downward to the inside of the filter drum 5 through the mounting seat 602 and the mounting block 603.

[0024] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, a resistance spring 604 is installed inside the mounting block 603 through a groove, and a scraper 605 is fixedly installed on the side of the resistance spring 604 away from the groove, and one end of the scraper 605 is in close contact with the inner wall of the filter drum 5. At the same time, the scraper 605 moving downward is in contact with the inner wall of the filter drum 5 through the elastic force of the resistance spring 604. The crystals attached to the inner wall of the filter drum 5 are scraped off by the rotating filter drum 5 and the scraper 605 moving continuously downward, thereby realizing the function of quickly peeling off the separated crystals.

[0025] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, a stabilizing frame 9 is fixedly sleeved on the outer side of the separation tank 2, and the bottom end of the stabilizing frame 9 is fixedly installed on the top of the support seat 1. A controller 10 is fixedly installed on the side of the support seat 1 close to the stabilizing frame 9. The separation tank 2 is stably fixed on the top of the support seat 1 through the stabilizing frame 9. The controller 10 is electrically connected to the drive motor 301, the servo motor 405, the electric push rod 601 and the suction pump 8 through wires, so that the operator can control the device to power on and run through the controller 10.

[0026] Working principle: The operator turns on the controller 10 to control the servo motor 405 to be powered on and run. The powered-on servo motor 405 drives the second rotating shaft 404 to rotate. The rotating second rotating shaft 404 drives the first rotating shaft 402 to rotate through the belt 403. The rotating first rotating shaft 402 drives the turntable 4 to rotate inside the separation tank 2. The rotating turntable 4 drives the filter drum 5 to rotate through the shaft seat. At the same time, it is clamped to the inside of the limit groove 202 through the limit ring 401, so that the turntable 4 will not be displaced when rotating inside the separation tank 2, ensuring the smooth rotation of the turntable 4 and the filter drum 5 inside the separation tank 2.

[0027] When the filter drum 5 rotates smoothly inside the separation tank 2, the unseparated crystals and mother liquor are delivered to the inside of the guide hopper 302 through the feed pipe 303, and at the same time, the driving motor 301 is energized to drive the guide hopper 302 to rotate through the shaft, and the rotating guide hopper 302 throws out the unseparated crystals and mother liquor inside through the through hole, and the thrown out crystals are evenly attached to the inner wall of the rotating filter drum 5. At the same time, the mother liquor is filtered through the through holes on the surface of the filter drum 5, and the filtered mother liquor falls into the separation tank 2 and the discharge port 7. Then the operator controls the suction pump 8 to be energized through the controller 10 to generate suction, and the suction force sucks the mother liquor inside the separation tank 2 and the discharge port 7 through the pipeline, thereby realizing the function of quickly separating the crystals from the mother liquor.

[0028] When the separated mother liquor inside the separation tank 2 and the discharge port 7 is sucked clean, the operator controls the electric push rod 601 to be energized and operated through the controller 10. The energized electric push rod 601 drives the scraper 605 to move downward to the inner wall of the filter drum 5 through the mounting seat 602 and the mounting block 603. At the same time, the scraper 605 moving downward is against the inner wall of the filter drum 5 through the elastic force of the resistance spring 604. The rotating filter drum 5 and the scraper 605 that continuously moves downward cooperate to scrape off the crystals attached to the inner wall of the filter drum 5, thereby realizing the function of quickly peeling off the separated crystals. The scraped crystals fall into the inside of the discharge port 7. Finally, the operator opens the sealing valve at the bottom of the discharge port 7 to open the conveying channel, which is convenient for conveying the crystals inside the discharge port 7 to the next process.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
