Description

Technical Field

[0001] The invention relates to the technical field of filters, in particular to a high-pressure filter. Background Art

[0002] High-pressure filters are widely used in small pharmaceutical factories, food and beverage, factories, mines, hospitals and laboratories. They are mainly used for filtering, clarifying and sterilizing liquids. They are mainly composed of a base, a cylinder, a filter membrane and an air pressurization component. During filtration, the liquid to be filtered passes through the filter membrane under pressure. Under the action of pressure, the filtrate is discharged through the filter membrane, while the solid particles are retained on the filter membrane to form a filter cake. By applying pressure, the efficiency and effect of filtration can be improved. When in use, the filter membrane needs to be placed on the filter membrane back plate of the base, and then the cylinder and the base are installed and fixed.

[0003] However, when the existing high-pressure filter is in use, the filter membrane is prone to displacement, arching and wrinkling when the filter membrane is placed, which is not easy to be found, affecting the efficiency and effect of filtration; during filtration, the filter membrane may be damaged, which is not easy to be found.

[0034] Each third reset mechanism comprises: A rectangular rod 701 is fixed to the top of the plug block 604 and passes through the top of the second connecting plate 602 and is fixed to the bottom of the moving column 605; The fifth spring 702 is sleeved on the side wall of the rectangular rod 701 , and the two ends of the fifth spring 702 are respectively fixed to the top of the plug block 604 and the bottom of the second connecting plate 602 , so as to guide and reset the movement of the plug block 604 and the movable column 605 .

[0035] Working principle: When in use, first place the filter membrane 106 on the top of the filter membrane back plate 103, then install and fix the cylinder 107 and the base 101. When installing, first sleeve the positioning hole 110 on the threaded column 105. When the second scraper 1402 abuts against the top of the filter membrane 106, the second sleeve rod 502 can slide into the second sleeve 501, and the second spring 503 is compressed. At the same time, start the motor 1602, and the rotation of the motor 1602 drives the rotation of the drive shaft 1603, and drives the rotating rod 11 and the mounting plate 12 to rotate through the soft connection mechanism, and then drives the first movable plate 1401 and the second scraper 1402 to rotate clockwise through the first telescopic mechanism. At this time, the filter membrane 106 can be automatically scraped and leveled to avoid arching, thereby ensuring the efficiency and effect of subsequent filtration; After the second scraper 1402 finishes scraping the filter membrane 106, when the lower end of the rubber rod 1502 abuts against the top of the filter membrane 106, the first spring 203 can be gradually compressed. At the same time, when the mounting plate 12 rotates, the rubber rod 1502 can be driven to slide on the top of the filter membrane 106 through the fixing plate 1501 and the second telescopic mechanism. If the filter membrane 106 is placed offset on the top of the filter membrane back plate 103, the lower end of the rubber rod 1502 can be inserted into the filter hole of the filter membrane back plate 103. At this time, the mounting plate 12 and the rotating rod 11 can no longer rotate. The block 604 can slide out from the first connection disk 601 and slide on the top of the first connection disk 601. At the same time, the moving column 605 is driven to move upward through the rectangular rod 701, and the fifth spring 702 is compressed. When the moving column 605 moves upward, it can push the moving ring 801 to move upward and drive the first connection block 802 to move upward synchronously. At this time, the distance change of the first connection block 802 can be detected by the distance sensor 805, so that before the cylinder 107 is installed and fixed, it can detect whether the filter membrane 106 is placed offset to ensure the efficiency and effect of filtration; At the same time, when the bottom of the cylinder 107 contacts the top of the base 101, the upper end of the first T-shaped guide rod 202 just contacts the bottom of the second movable plate 301. If the filter membrane 106 is wrinkled, the thickness of the filter membrane 106 will increase. When the rubber rod 1502 slides on the top of the filter membrane 106, it can push the rubber rod 1502 and the first T-shaped guide rod 202 to continue to move upward. At this time, the connecting plate 302 can be driven by the second movable plate 301 to move upward along the side wall of the second T-shaped guide rod 901. At the same time, the third spring 902 is compressed and causes the connecting plate 302 to abut against the inclined surface 304, thereby pushing the moving block 305 to move in the direction close to the second connecting block 1002. At the same time, the fourth spring 902 is compressed and causes the connecting plate 302 to abut against the inclined surface 304, thereby pushing the moving block 305 to move in the direction close to the second connecting block 1002. The spring 1003 is compressed. When the moving block 305 moves, the plug rod 306 is driven to move through the connecting rod 401 and the fixed tube 403, so that the end of the plug rod 306 can be against the inner wall of the cylinder 107. At the same time, the reset spring 402 is compressed. When the plug rod 306 is aligned with the insertion hole 303, the plug rod 306 can be inserted into the insertion hole 303 for limiting under the action of the reset spring 402. At this time, the mounting plate 12 and the rotating rod 11 cannot continue to rotate. At this time, the moving ring 801 and the first connecting block 802 can also be driven to move upward and be detected by the distance sensor 805, so that the wrinkle state of the filter membrane 106 can be detected before the cylinder 107 is installed and fixed, so as to ensure the efficiency and effect of filtration; After the test is completed, a plurality of locking nuts 111 are screwed and fixed on the side wall of the threaded column 105, so that the cylinder 107 can be installed and fixed on the top of the base 101. Then, liquid can be supplied through the liquid inlet 108 and closed. Then, air is supplied into the cylinder 107 through the air pump 112 for pressurization, and the filtering operation can be performed. The filtered liquid enters the liquid collecting tank 102 through the filter membrane back plate 103 and flows out through the liquid outlet 104, while impurities are filtered on the surface of the filter membrane 106. During filtration, the mounting plate 12 and the second scraper 1402 can be driven by the driving mechanism to rotate counterclockwise. At this time, impurities on the surface of the filter membrane 106 can be automatically scraped off and collected in the collecting tank 1404. At the same time, when the mounting plate 12 rotates, the first scraper 13 can be driven to rotate synchronously, so that the residual liquid on the inner wall of the cylinder 107 can be scraped off and cleaned, thereby ensuring the efficiency and effect of filtration. Moreover, when the filter membrane 106 is damaged, the lower end of the rubber rod 1502 can also be inserted into the filter hole of the filter membrane back plate 103, so that the mounting plate 12 and the rotating rod 11 cannot continue to rotate, and it can also be detected by the distance sensor 805, so that during filtering, the damage of the filter membrane 106 can be detected in time to ensure the efficiency and effect of filtration.
