Set the preset number of filtration circles, and after the end, pump the reaction solution into the centrifugation unit for centrifugation to obtain a reaction solution with impurities and insoluble substances fully filtered; the reaction stirring unit 30 is: relying on a motor to drive a plurality of stirring plates inside the reaction tank 1 to perform the operation of mixing and stirring the raw materials.

[0036] Secondly, the rotary filtration driving component 6 is arranged below the filtration box 3. The output end of the rotary filtration driving component 6 penetrates through the filtration box 3 and is fixedly connected to the cross metal block 7. The rotary filtration shaft 9 has a cross groove 11. The cross magnet 8 is arranged inside the cross groove 11. The cross metal block 7 is adapted to the cross groove 11. A plurality of the filter plates 10 are sequentially arranged around the outside of the rotary filtration shaft 9. The rotary filtration driving component 6 is a self-locking motor. The output end of the rotary filtration driving component 6 drives the cross metal block 7 to rotate, and then drives the rotary filtration shaft 9 and a plurality of the filter plates 10 to rotate through the cooperation of the cross groove 11, so as to filter the impurities and insoluble substances in the filtration chamber 5. The rotary filtration shaft 9 adsorbs the cross metal block 7 through the cross magnet 8, so as to achieve fixation; in addition, the sizes of the filter holes of the filter plates 10 in each filtration chamber 5 are different, so as to filter impurities or insoluble substances of different sizes.

The transverse driving component 12 is an electric slide rail, and the electric slide rail is used to drive the filtration box 3 installed above to move, so that it can move to the replacement units on both sides to replace the filter plates 10. When replacement is needed, the subsequent clamping mechanism clamps the handle 13, and then the rotary filtration shaft 9 is pulled out; in addition, the flow pump 14 can input the reaction liquid in the bottom area of each filtration chamber 5 upward, so as to avoid uneven circulation of the reaction liquid.

[0038] In addition, the bracket 15 is arranged on one side of the reaction tank 1, and a plurality of the clamping mechanisms are sequentially distributed below the bracket 15; the replacement rotating member 16 is arranged below the bracket 15, the output end of the replacement rotating member 16 is fixedly connected to the replacement lifting member 17, one ends of two clamping jaws 18 and two clamping driving members 19 are rotatably connected to the output end of the replacement lifting member 17, the two clamping jaws 18 and the two clamping driving members 19 are symmetrically distributed, the clamping driving member 19 is located on one side of the clamping jaw 18, and the output end of the clamping driving member 19 is rotatably connected to one side of the clamping jaw 18. The camera 20 is installed at the output end of the replacement lifting member 17 and is located between the two clamping jaws 18. The bracket 15 supports the plurality of clamping mechanisms. When it is necessary to pull out the rotary filter shaft 9, first the camera 20 photographs the position of the handle 13, then the replacement rotating member 16 is started to drive the clamping jaw 18 to rotate and align with the handle 13. At this time, the replacement lifting member 17 is started to drive the clamping jaw 18 to approach the handle 13. At this time, the clamping driving member 19 is started to drive the clamping jaw 18 to clamp the handle 13. Finally, the clamping jaw 18 moves upward so that the cross metal block 7 is separated from the cross magnet 8, and the rotary filter shaft 9 is pulled out. In addition, for the brackets 15 on both sides of the reaction tank 1, one is used to install the unused rotary filter shaft 9 and the filter plate 10, and the other is used to pull out and store the rotary filter shaft 9 and the filter plate 10 that need to be cleaned.

[0040] Again, the docking pipe 27 communicates with the lower part of the transfer groove 22. One end of the storage tank 28 is connected to the docking pipe 27, and the clamping rod 29 sequentially penetrates through the docking pipe 27 and the storage tank 28. After centrifugation is completed, the clamping rod 29 is pulled out, and the storage tank 28 can be taken away from the docking pipe 27, and then the centrifuged reaction liquid can be taken out.
