Description

Technical Field

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

[0002] High-pressure filters are widely used in small pharmaceutical factories, food and beverage factories, factories, mines, hospitals, laboratories and other units. They are mainly used for liquid filtration, clarification and sterilization treatment. They mainly consist 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 passes through the filter membrane and is discharged, while the solid particles are retained on the filter membrane to form a filter cake. By means of pressurization, the filtration efficiency and effect can be improved. When in use, the filter membrane needs to be placed on the filter membrane back plate of the base. Then, the cylinder is installed and fixed to the base.

[0003] However, when the existing high-pressure filter is in use, when placing the filter membrane, the filter membrane is prone to shift, arch and wrinkle, which is not easy to be detected, affecting the filtration efficiency and effect; during filtration, the filter membrane may be damaged, which is not easy to be detected. At the same time, liquid is likely to remain on the inner wall of the cylinder, and the impurities on the filter membrane will gradually increase, which will also affect the filtration efficiency and effect.

[0081] A driving mechanism, arranged at the top of the cylinder body 107, for driving the rotating rod 11 to rotate;

[0082] A leveling mechanism, arranged below the installation plate 12, enabling the leveling mechanism to scrape on the upper surface of the filter membrane 106, for scraping and cleaning the filter membrane 106;

At this time, the filter membrane 106 can be automatically leveled to avoid arching, ensuring the efficiency and effect of subsequent filtration. And during subsequent filtration, the mounting plate 12 and the second scraping plates 1402 can be driven to rotate counterclockwise through the driving mechanism. At this time, the impurities on the surface of the filter membrane 106 can be automatically scraped and enter the collection groove 1404 for collection.

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 at the same time, the second spring 503 is compressed. Meanwhile, start the motor 1602. 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 flexible connection mechanism, and then drives the first moving 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 leveled to avoid arching, ensuring the efficiency and effect of subsequent filtration;

[0132] After the second squeegee 1402 finishes leveling 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, it can drive the rubber rod 1502 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 backplane 103, the lower end of the rubber rod 1502 can be inserted into the filter hole of the filter membrane backplane 103. At this time, the mounting plate 12 and the rotating rod 11 cannot rotate any further. At this time, the plug 604 can slide out of 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 by 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 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 be detected whether the filter membrane 106 is placed offset, ensuring the filtration efficiency and effect;

[0133] 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 moving 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 move upward continuously. At this time, the connecting plate 302 can be driven by the second moving 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 the connecting plate 302 abuts against the inclined surface 304, so as to push the moving block 305 to move in the direction close to the second connection block 1002. At the same time, the fourth spring 1003 is compressed. When the moving block 305 moves, the insertion rod 306 is driven to move through the connecting rod 401 and the fixed pipe 403, so that the end of the insertion rod 306 can abut against the inner wall of the cylinder 107. At the same time, the return spring 402 is compressed. When the insertion rod 306 is aligned with the insertion hole 303, the insertion rod 306 can be inserted into the insertion hole 303 under the action of the return spring 402 for limiting. At this time, the mounting plate 12 and the rotating rod 11 cannot rotate any further. At this time, it can also drive the moving ring 801 and the first connection block 802 to move upward and be detected by the distance sensor 805, so that before the cylinder 107 is installed and fixed, the wrinkled state of the filter membrane 106 can be detected, ensuring the filtration efficiency and effect;

[0134] After the detection 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 body 107 can be installed and fixed on the top of the base 101. Then, liquid can be supplied through the liquid inlet 108 and then closed. Then, air is supplied into the cylinder body 107 by the air pump 112 for pressurization, and then the filtering operation can be carried out. 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 the impurities are filtered on the surface of the filter membrane 106;

[0135] During the filtering process, the driving mechanism can drive the mounting plate 12 and the second scraper 1402 to rotate counterclockwise. At this time, the impurities on the surface of the filter membrane 106 can be automatically scraped off and collected into the collection tank 1404. At the same time, when the mounting plate 12 rotates, it can drive the first scraper 13 to rotate synchronously, so as to scrape and clean the residual liquid on the inner wall of the cylinder body 107, ensuring the filtering efficiency and effect;

[0136] Moreover, when the filter membrane 106 is damaged, the lower end of the rubber rod 1502 can also be inserted into the filtering holes of the filter membrane back plate 103, so that the mounting plate 12 and the rotating rod 11 cannot continue to rotate, and this can also be detected by the distance sensor 805. Therefore, during the filtering process, the damage condition of the filter membrane 106 can be detected in time, ensuring the filtering efficiency and effect.
