[0015] Compared with the prior art, the beneficial effects of this application are: 1. In the present application, the Chinese patent medicine liquid can be filtered by setting the feed pipe, the discharge pipe, the feed valve, the discharge valve, the valve, the filter device and the backwashing device. After filtering, the impurities in the filter device can be backwashed under the action of the backwashing device to increase the service life of the filter device. At the same time, while the filter device is backwashing, the Chinese patent medicine liquid can be filtered by another filter device to achieve uninterrupted filtering; 2. In the present application, the filter body can be installed between the top plate and the support plate by means of the filter shell, connecting pipe, supporting ring, top cover, supporting column, top plate, supporting plate, connecting column, bottom plate, upper water inlet clamping hole, lower water inlet clamping hole, clamping groove, filter body, first bolt and second sealing ring, and the Chinese patent medicine liquid can be filtered simultaneously by multiple filter bodies. When one of them is seriously blocked, the filtering of the Chinese patent medicine liquid is not affected. At the same time, when the top cover is fixed by the first bolt, the top cover can push the top plate to move downward through the supporting column, and the top plate pushes the supporting plate to move downward through the filter body, so that the supporting plate is closely fitted with the second sealing ring, and the support plate and the support ring are sealed; 3. In the present application, by setting the filter column shell, fixing ring, first sealing ring, placement groove, card plate, limiting column, rubber block, fixing block and reed, the Chinese patent medicine liquid can be filtered under the action of the filter column shell, and the Chinese patent medicine liquid can be diverted by multiple filter column shells at the same time, reducing the pressure of the filter column shell. At the same time, when one of them is seriously blocked, it can be filtered through other filter column shells to reduce the accumulation of Chinese patent medicine liquid. After the filter column shell is blocked, the multiple fixing rings and filter column shells can be taken out at one time directly through the top plate. At this time, the filter column shell is moved downward, and the filter column shell drives the fixing ring to move, and the fixing ring is taken out from the top plate. At this time, the filter column shell can be cleaned or replaced, and then the filter column shell is installed back to the bottom of the top cover through the fixing ring. At this time, the rubber block, reed and limiting column are used to push the fixing block into the card slot opened in the top plate to position the fixing ring. Finally, the multiple filter column shells are passed through the lower water inlet card hole opened on the support plate to achieve maintenance of the multiple filter column shells. 4. In the present application, by setting the discharge pipe, valve, fixed box, connecting body, fixed pipe, first connecting pipe, second connecting pipe, third connecting pipe, fourth connecting pipe, first water pump, second water pump, water inlet tank and liquid discharge valve, the Chinese patent medicine liquid in the filter shell can be pumped into the fixed box under the action of the second water pump, and filtered through the filter residue device in the fixed box. As the Chinese patent medicine liquid in the fixed box gradually increases, the Chinese patent medicine liquid enters the discharge pipe through the fixed pipe and the first connecting pipe. After that, the first water pump pumps the Chinese patent medicine liquid in the discharge pipe into the filter shell through the second connecting pipe and the third connecting pipe, so as to realize the backwashing of the filter column shell by the Chinese patent medicine liquid. At the same time, under the action of the first water pump and the second water pump, the flow rate of the Chinese patent medicine liquid can be increased, thereby improving the backwashing effect; 5. In the present application, by setting a fixed frame, a first sealing frame, a filter plate, a connecting block, a fixed plate, a positioning block, a second bolt, a rubber ball, a sliding rod, a sealing plate, a third bolt, an internal thread block, a fixed column, a positioning plate, a push frame, a second sealing frame, a slide groove, a slider, a mounting block and a supporting frame, the backwashed Chinese patent medicine liquid can be filtered through the filter plate in the fixed frame. During the filtering process, the first sealing frame and the second sealing frame can be sealed to improve the filtering effect. After the backwashing is completed, the third bolt is rotated. The third bolt drives the fixed column to move upward under the action of the internal thread block. The fixed column drives the slider to move in the slide groove opened in the push frame through the positioning plate. At this time, the two third bolts can be rotated alternately until the slider pushes the push frame to The second bolt can be rotated to remove the second bolt, and the fixed plate can be taken out of the fixed box under the action of the sliding rod and the connecting block, and then the impurities in the fixed frame can be cleaned. After cleaning, the fixed frame can be reset, and then the fixing plate, the connecting block and the sealing plate can be fixed by the second bolt. At this time, the sealing plate is tightly fitted with the fixed box to prevent leakage of the Chinese patent medicine liquid, and then the third bolt is rotated. The third bolt drives the positioning plate to push the push frame downward through the fixing column, and the push frame pushes the fixed frame to move downward. In the process of the fixed frame moving downward, the connecting block moves downward on the outside of the sliding rod. At this time, the rubber ball is deformed by force, and at the same time, the first sealing frames arranged on the upper and lower sides of the fixed frame are tightly fitted with the push frame and the supporting frame respectively to achieve sealing.

[0024] Working process: When the filtering device of the Chinese patent medicine is used, the power is first turned on, and then the decocted Chinese patent medicine liquid is fed into the feed pipe 1 through the feed valve 3. At this time, the valve 5 on the left side of the feed pipe 1 and the discharge pipe 2 is opened, and the valve 5 on the right side of the feed pipe 1 and the discharge pipe 2 is closed at the same time. The Chinese patent medicine liquid enters the left filter shell 61 through the feed pipe 1, and then the Chinese patent medicine liquid enters the fixed ring 672 through the upper water inlet hole 665 opened on the top plate 661. At the same time, the fixed ring 672 is tightly fitted with the top plate 661 and the support plate 662 through the first sealing ring 673. At this time, the Chinese patent medicine liquid can only enter the filter column shell 671 through the fixing ring 672. At the same time, the second sealing ring 69 can prevent the Chinese patent medicine liquid from passing through the support plate 662 and the support plate 662. The liquid flows through the gap between the rings 63 and is filtered through the filter column shell 671. Impurities in the Chinese patent medicine liquid remain in the filter column shell 671, and the effective ingredients are discharged through the discharge pipe 2 and the discharge valve 4. After long-term use, a large amount of impurities remain in the filter column shell 671. At this time, the feed valve 3, the discharge valve 4 and the valve 5 are closed, and then the first water pump 726 and the second water pump 727 are started. At this time, the first water pump 726 extracts the Chinese patent medicine liquid in one end of the discharge pipe 2 through the second connecting pipe 723, and then sends it to the filter shell 61 on one side through the third connecting pipe 724. At the same time, the second water pump 727 pumps the Chinese patent medicine liquid above the top plate 661 of the filter shell 61 into the fixed box 71 through the fourth connecting pipe 725, and the Chinese patent medicine liquid directly flows into In the fixed frame 731 provided in the fixed box 71, the Chinese patent medicine liquid is filtered by the filter plate 733 provided in the fixed frame 731, and the filtered Chinese patent medicine liquid flows downward to the bottom of the fixed box 71. At the same time, the second sealing frame 756 provided on the outside of the push frame 755 prevents the Chinese patent medicine liquid from directly entering the bottom of the fixed box 71 without being filtered. The first sealing frame 732 provided on the upper and lower sides of the fixed frame 731 is sealed to seal the fixed frame 731 with the push frame 755 and the support frame 77, so that the Chinese patent medicine liquid is uniformly filtered through the filter plate 733. As the Chinese patent medicine liquid in the fixed box 71 gradually increases, the Chinese patent medicine liquid flows into the first connecting pipe 722 through the water inlet trough 728 opened at the bottom of the fixed pipe 721, and passes through the first connecting pipe 722. A connecting pipe 722 allows the Chinese patent medicine liquid to flow back into the discharge pipe 2, and then under the action of the first water pump 726, it is sent into the filter shell 61 to form a circulation. At this time, the Chinese patent medicine liquid in the filter shell 61 is pumped upward by the second water pump 727. At the same time, the Chinese patent medicine liquid drives the impurities in the filter column shell 671 to move upward and enter the fixed box 71 for filtration, thereby cleaning the impurities in the filter column shell 671. While cleaning the filter column shell 671 on one side, the valve 5 and the feed valve 3 provided on the side of the feed pipe 1 close to the filter column shell 671 being cleaned can be appropriately opened to send part of the unfiltered Chinese patent medicine liquid into the filter shell 61, and the Chinese patent medicine liquid in the filter shell 61 is supplemented to make the backwashing more stable. During the backwashing,The valve 5 on the side of the feed pipe 1 and the discharge pipe 2 close to the other filter shell 61 can be opened. At this time, the Chinese patent medicine liquid can continue to be filtered through the other filter column shell 671 to achieve uninterrupted filtration. After the backwashing is completed, the first water pump 726 and the second water pump 727 are turned off, and the liquid discharge valve 79 is opened. The Chinese patent medicine solution in the fixed box 71 can be discharged through the liquid discharge valve 79 for continued use. After that, the second bolt 743 can be taken out from the positioning block 742 and the mounting block 76, and then the third bolt 751 is rotated. The third bolt 751 drives the fixed column 753 to move upward through the internal thread block 752. The fixed column 753 drives the slider 758 to move upward in the slide groove 757 opened in the push frame 755 through the positioning plate 754. When the top inner wall of the slide groove 757 provided in the push frame 755 contacts, the slider 758 can drive the push frame 755 to move upward, so that the push frame 755 leaves the first sealing frame 732 fixedly connected to the fixed frame 731, and then the fixed plate 741 drives the connecting block 734 to move through the sliding rod 745, and the connecting block 734 drives the fixed frame 731 to leave the fixed box 71, and then the impurities in the fixed frame 731 are cleaned. After the cleaning is completed, the fixed frame 731 is installed back into the fixed box 71, and then the second bolt 743 is passed through the positioning block 742 and the mounting block 76 for screw connection, so as to install and position the positioning block 742 and the fixed plate 741, so that the sealing plate 746 fixedly connected to the fixed plate 741 is tightly fitted with the fixed box 71, and the fixed frame 731 is set. When the locking cam 752 is in the state of being moved downwardly, the locking cam 754 is in the state of being moved downwardly, and the locking cam 754 is in the state of being moved downwardly. The second sealing frame 756 is tightly fitted with the fixed box 71 to achieve sealing. When the filter column shell 671 on the other side needs to be backwashed, the above-mentioned method is used to backwash the filter column shell 671 on the other side. At this time, filtering is continued through the filter column shell 671 on one side. When long-term filtration causes blockage in the filter column shell 671, the valve 5 on one side of the feed pipe 1 is first closed in the above-mentioned manner, and then the filtered Chinese patent medicine liquid in the filter shell 61 is discharged as much as possible through the discharge valve 4. After that, the first bolt 68 is removed. At this time, the top cover 64 can be removed, and then the top plate 661 is moved upward. The top plate 661 drives the fixing ring 672 and the filter column shell 671 to move upward through the slot 667, and the filter column shell 671 is taken out of the filter shell 61.Then, the filter column housing 671 is directly moved downward, and the filter column housing 671 drives the fixing ring 672 to move downward. At this time, the card plate 675 is pushed toward the fixing ring 672 under the action of the card slot 667 opened on the top plate 661, and the fixing ring 672 is taken out from the upper water inlet card hole 665 opened on the top plate 661. After that, the filter column housing 671 can be cleaned or replaced, and then the fixing ring 672 is put into the upper water inlet card hole 665 opened on the top plate 661. Under the action of the top plate 661, the card plate 675 is pushed to move on one side of the arc-shaped setting. At this time, the card plate 675 pushes the limiting column 676 to move in the rubber block 677. The limiting column 676 pushes the spring 679 set in the rubber block 677 to deform. At the same time, the spring 679 pushes the rubber block 677 to deform through the deformation groove opened in the rubber block 677. After the card block moves to the position of the card slot 667 opened in the top plate 661, the elastic force of the rubber block 677 and the spring 679 pushes The movable limit column 676 is reset, and the limit column 676 pushes the card plate 675 to be inserted into the card groove 667 opened on the top plate 661, so as to install the fixing ring 672, and then the multiple filter column shells 671 pass through the lower water inlet card hole 666 opened on the support plate 662, so that the bottom of the fixing ring 672 enters the lower water inlet card hole 666 opened on the support plate 662, and then the top cover 64 is covered on the top of the filter shell 61. At this time, the bottom of the support column 65 provided on the filter shell 61 contacts the top plate 661, and the first bolt 68 passes through the top cover 64, so that the first bolt 68 is spirally connected to the filter shell 61, thereby fixing the top cover 64. At the same time, the top cover 64 pushes the top plate 661 downward through the support column 65, so that the first sealing ring 673 fixedly connected on the upper and lower sides of the fixing ring 672 is tightly fitted with the top plate 661 and the support plate 662 respectively, and at the same time, the second sealing ring 69 fixedly connected to the support plate 662 and the support ring 63 is tightly fitted to achieve sealing. ,
