Specifically, the cover body 5 and the outer barrel 4 can be connected by bolts so that the cover body 5 can be removed from the outer barrel 4 so as to thoroughly clean the inside of the outer barrel 4.

[0025] like Figure 2 As shown, a filter cartridge 6 is disposed in the outer barrel 4, and a plurality of filter holes are evenly distributed on the side wall of the filter cartridge 6. The filter cartridge 6 is cylindrical with an open upper end, and the filter cartridge 6 is driven by a power device and rotates around its own axis. In this embodiment, a sewage pipe 7 is rotatably installed at the bottom of the outer barrel 4 through a bearing. The sewage pipe 7 vertically penetrates the bottom wall of the outer barrel 4.

A reserved hole for the sewage pipe to pass downward is provided on the support plate 3. A sealing plate 8 is installed at the lower end of the sewage pipe 7 by bolts. The sewage pipe 7 is driven by a power device and rotates around its own axis. The driving device is specifically a first motor 9 installed on the top of the support plate 3 by bolts. The rotating shaft of the first motor 9 passes downward through the support plate 3 and is fixedly installed with a driving pulley. A driven pulley is fixedly installed on the outer side of the lower end of the sewage pipe 7, and a belt 10 is connected between the driving pulley and the driven pulley; a liquid inlet pipe 11 with one end extending downward to the upper end of the filter cartridge 6 is welded on the cover body 5, and the other end of the liquid inlet pipe 11 extends to the outside of the outer barrel 4. A liquid outlet pipe 12 is provided on one side of the bottom of the outer barrel 4.

[0026] When in use, the waste liquid generated during the production of the injection liquid is injected into the filter cartridge 6 through the liquid inlet pipe 11, and the first motor 9 drives the drain pipe 7 to rotate, and then the drain pipe 7 drives the filter cartridge 6 to rotate, and the separation of liquid and solid impurities is accelerated under the action of centrifugal force, so that the pure liquid waste liquid passes through the filter cartridge 6 and is thrown out to the inside of the outer barrel 4 and finally discharged through the liquid outlet pipe 12, while the solid impurities remain inside the filter cartridge 6. When it is necessary to clean the inside of the filter cartridge 6, the sealing plate 8 at the lower end of the drain pipe 7 is removed so that the solid impurities in the filter cartridge 6 can be discharged through the drain pipe 7.

[0027] A door frame 13 is fixedly mounted on the bottom plate 1.

[0028] like Figures 2 to 4 As shown, a vertically penetrating mounting hole is provided in the middle of the cross plate 16, and a vertically extending support rod 20 is fixedly installed in the mounting hole by bolts. The lower end of the support rod 20 extends into the filter cartridge 6 and a cross rod 21 is movably installed. A scraper 22 matching the inner wall of the filter cartridge 6 is fixedly installed at one end of the cross rod 21. The scraper 22 includes a scraper bracket 23, and the scraper bracket 23 is welded to one end of the cross rod 21. A flexible scraper strip 24 is embedded on one side of the scraper bracket 23 to reduce the wear of the inner wall of the filter cartridge 6. The scraper strip 24 matches the inner wall of the filter cartridge 6.

[0029] In order to improve the efficiency of the scraper 22 in scraping off impurities on the inner wall of the filter cylinder 6, the scraper 22 is arranged in a spiral shape.

[0030] like Figure 4 As shown, a sleeve 25 is welded to the lower end of the support rod 20, and the cross bar 21 is slidably installed in the sleeve 25 along the radial direction of the filter cylinder 6. A guide bar 26 extending along its length direction is integrally formed on the inner wall of the sleeve 25, and a guide groove 27 matching the guide bar 26 is provided on the outer side of the cross bar 21 to prevent the cross bar 21 from rotating in the sleeve 25 and causing the angle of the scraper 22 to change; the support rod 20 is a hollow tube, and a core shaft 28 driven by a power component and moving vertically is provided in the support rod 20.

[0032] Specifically, the hydraulic cylinder 32 is extended to drive the core shaft 28 to move upward relative to the support rod 20, and then the core shaft 28 drives the cross bar 21 to move to one side along the sliding sleeve 25 through the connecting rod 31, so that the scraper 22 is attached to the inner wall of the filter cylinder 6. When the filter cylinder 6 rotates, the impurities on the inner wall of the filter cylinder 6 are scraped off by the scraper 22, thereby avoiding the clogging of the filter holes and improving the filtering efficiency of the filter cylinder 6. At the same time, the second motor 18 can drive the screw rod 19 to rotate in a specific direction so that the cross plate 16 moves down slowly, and then the cross plate 16 drives the scraper 22 to move down along the inner wall of the filter cylinder 6 through the support rod 20, and the impurities are pushed to the bottom of the filter cylinder 6 by the scraper 22, so that the cleaning effect of the filter cylinder 6 is better.

[0033] When the scraper 22 moves down and approaches the bottom of the filter cartridge 6, the second motor 18 drives the screw rod 19 to rotate in the opposite direction, so that the cross plate 16 moves up slowly, and the support rod 20 and the scraper 22 return to their original positions. At the same time, the hydraulic cylinder 32 can be contracted to drive the core shaft 28 to move downward relative to the support rod 20, and then the core shaft 28 drives the cross bar 21 to move in the opposite direction along the sliding sleeve 25 through the connecting rod 31, so that the scraper 22 is separated from the inner wall of the filter cartridge 6, so as to prevent the scraper 22 from pushing impurities to the top of the filter cartridge 6 when it moves up and returns to its original position.

[0034] like Figure 3 and Figure 5 As shown, in order to improve the rotation stability of the filter cartridge 6, a sleeve 34 coaxially arranged with the filter cartridge 6 is rotatably mounted on the cover body 5 through a bearing, the sleeve 34 vertically penetrates the cover body 5, and the support rod 20 is movably arranged inside the sleeve 34; an annular support plate 35 that fits the inner wall of the filter cartridge 6 is also fixedly mounted on the lower end of the sleeve 34, and a coaxially arranged mounting sleeve 36 is fixedly mounted on the inner side of the support plate 35 through a connecting plate, and the mounting sleeve 36 is fixedly mounted on the outer side of the lower end of the sleeve 34 through bolts. An annular rubber ring 37 is embedded on the outer side of the support plate 35, and when the cover body 5 is buckled on the top of the outer barrel 4, the support plate 35 enters the upper end of the filter cartridge 6, and the rubber ring 37 makes the support plate 35 tightly combined with the inner wall of the filter cartridge 6, and the support plate 35 provides support for the upper end of the filter cartridge 6, thereby improving the rotation stability of the filter cartridge 6.
