[0028] Furthermore, the filter mechanism further includes a spiral blade 8 and a conical blanking pipe 9. The spiral blade 8 is fixedly installed on the inner wall of the feed pipe 5. The conical blanking pipe 9 is fixedly installed at the lower end of the feed pipe 5. A filter screen 10 is fixedly installed at the lower end of the inner wall of the conical blanking pipe 9.

[0029] Furthermore, the silica sol raw material can be pre-filtered through the filter screen 10 to prevent larger impurities from blocking the ultrafiltration membrane body 3 and affecting the use of the ultrafiltration membrane body 3. The spiral blade 8 is used to slow down the falling speed of the silica sol raw material to prevent too much silica sol raw material from being filtered by the filter screen 10 at one time, causing the filter screen 10 to be blocked and affecting the subsequent concentration of the silica sol raw material, improving the working efficiency of the device, and thus improving the production efficiency of silica sol.

[0030] Furthermore, the replacement mechanism further includes a fixing plate 12 and two moving plates 13. The two moving plates 13 are respectively threadedly connected to the outer surfaces of the two threaded rods 6. The fixing plate 12 is fixedly installed on the adjacent ends of the two moving plates 13. A rectangular groove 21 is opened on the lower inner wall of the working box 1 corresponding to the position of the fixing plate 12. A groove adapted to the lower end of the ultrafiltration membrane body 3 is opened on the upper surface of the fixing plate 12. Two connecting boxes 14 are fixedly installed on the front surface of the installation box 7. The upper ends of the two threaded rods 6 respectively rotate through the interiors of the two connecting boxes 14, and the rear ends of the two connecting boxes 14 respectively extend into the installation box 7.

[0031] Further, a rotating rod 15 is rotatably installed on the inner wall of the installation box 7. The left end of the rotating rod 15 rotatably penetrates through the outer surface of the working box 1. Two first bevel gears 16 are fixedly installed on the outer surface of the rotating rod 15. Connecting rods 17 are rotatably installed on the rear surfaces of the two connecting boxes 14. The front ends of the two connecting rods 17 respectively rotatably extend into the two connecting boxes 14.

[0034] Further, by starting the motor 23, the two threaded rods 6 rotate, driving the fixing plate 12 to move downward, so that the ultrafiltration membrane body 3 is no longer fixed. Then, moving the mounting plate 2 and the second conical feed pipe 11 upward can replace the ultrafiltration membrane body 3 more conveniently, reducing the replacement efficiency of the ultrafiltration membrane body 3 by workers, thereby improving the use efficiency of the device, and further improving the practicability of the device.

[0035] Working principle: When using this device, the silica sol raw material is added into the interior of the feeding pipeline 5 through the first conical feeding pipe 4. The silica sol raw material slowly moves downward through the spiral blades 8 arranged inside the feeding pipeline 5. When it enters the interior of the conical discharging pipe 9, it falls onto the filter screen 10. The silica sol raw material is filtered through the filter screen 10, and the impurities contained in the silica sol raw material are filtered out. The filtered raw material leaves the interior of the conical discharging pipe 9 and enters the interior of the second conical feeding pipe 11, and then enters the inlet end of the ultrafiltration membrane body 3. Filtration is carried out inside the ultrafiltration membrane body 3. The filtered water enters the lower end of the ultrafiltration membrane body 3 and exits through the water outlet on the ultrafiltration membrane body 3, reaching the interior of the working box 1. Then, the water outlet on the working box 1 is opened to discharge the water. The concentrated silica sol leaves through the silica sol outlet on the ultrafiltration membrane body 3. When the ultrafiltration membrane body 3 needs to be replaced after a long time of use, the movable door 22 is opened, the ultrafiltration membrane body 3 is held firmly, the motor 23 is started, the output end of the motor 23 drives the rotating rod 15 fixedly connected to its output end to rotate, so that the two first bevel gears 16 fixed on the rotating rod 15 rotate. The two second bevel gears 18 meshed with the two first bevel gears 16 rotate. The two second bevel gears 18 drive the two third bevel gears 19 to rotate through the two connecting rods 17. The two fourth bevel gears 20 meshed with the two third bevel gears 19 rotate, thereby driving the two threaded rods 6 fixedly connected to the two fourth bevel gears 20 to rotate. The two moving plates 13 threadedly connected to the two threaded rods 6 move downward, so that the fixing plate 12 moves downward, and then the mounting plate 2 and the second conical feeding pipe 11 are pushed upward. At this time, the ultrafiltration membrane body 3 can be removed to replace the ultrafiltration membrane body 3, reducing the difficulty of replacing the ultrafiltration membrane body 3.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
