Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, and particularly to a filter cartridge device with an anti-blocking structure. Background Art

[0002] Filters are widely used in sewage treatment, seawater treatment, chemical production, industrial processing and other processes to filter and remove impurities from the liquid material and filter out the impurities from the liquid material. However, during the use of existing filters, their filter screens are often prone to blockage, and manual disassembly is required for cleaning, and then reinstallation after cleaning, which is inconvenient to use.

[0003] In the prior art, an anti-blocking centrifugal cylinder type coating filtering device with the publication number of "CN112742094A" includes a housing and a feed pipe penetrating the upper surface of the housing. A discharge pipe is installed at the bottom of the housing. A feed hopper rotatably communicated with the feed pipe is installed on the upper surface of the housing. A driving mechanism for driving the feed pipe to rotate is provided on the housing. A filter cylinder is rotatably connected to the inner top surface of the housing. The lower end of the feed pipe penetrates the top surface of the filter cylinder and extends into the filter cylinder. A plurality of centrifugal pipes are fixedly communicated with the side wall of the feed pipe, and the plurality of centrifugal pipes are arranged in an equidistant array. This anti-blocking centrifugal cylinder type coating filtering device can promote the rapid progress of coating filtration through centrifugal action, improve work efficiency, and shake off the dust and impurities intercepted on the surface to the bottom of the filter cylinder through the reciprocating contraction and shaking of the flexible filter screen, preventing the occurrence of blockage problems, and there is no need to frequently replace the flexible filter screen, so that the filtration can be continuously and effectively carried out.

[0004] However, during its use, there are still obvious defects: the above device can only clean the blocked flexible filter screen. However, after use, a large amount of impurities will also adhere to the outer surface of the feed pipe. If not cleaned in time, it will still contaminate the material. Therefore, the device needs to be improved. Summary of the Invention

[0034] Embodiment Three:

[0035] Based on the above Embodiment One and Embodiment Two, the specific structure of the flushing device is further disclosed and defined in this embodiment. Specifically: The flushing device includes a plurality of backwashing pipes 12. The backwashing pipes 12 are connected to the water storage plate 10. A one-way pressure relief valve 121 is arranged in the backwashing pipes 12, and a dust-proof net 13 is arranged in the backwashing pipes 12. After the water pump 11 is started, the liquid in the backwashing water storage tank 6 will enter the water storage plate 10 through the water diversion pipe 9 and then enter the backwashing pipes 12. When the pressure at the position of the one-way pressure relief valve 121 exceeds a predetermined value, the pressure relief valve 121 opens, so that the liquid sprays out from the backwashing pipes 12 to backwash the filter screen 3, thereby removing the blockages in the filter screen holes.

[0036] Working Principle:

[0037] During use, the second electric control valve 8 and the third electric control valve 42 are closed, and the liquid to be filtered is guided into the inside of the cylinder body 1 through the water inlet pipe 2. After the liquid passes through the filtration of the filter screen 3, the impurities are intercepted, and the filtered liquid flows out through the water outlet pipe 4.

[0038] After using for a period of time, the filter screen 3 can be backwashed. Specifically, first, the second electric control valve is opened, so that a part of the liquid flowing through the water outlet pipe 4 enters the backwashing water storage tank 6 through the diversion pipe 7 for storage. Then, the water pump 11 is started, and the liquid in the backwashing water storage tank 6 is pumped to the water storage plate 10 through the water diversion pipe 9 and then enters the backwashing pipes 12. When the pressure at the position of the one-way pressure relief valve 121 exceeds a predetermined value, the pressure relief valve 121 opens, so that the liquid sprays out from the backwashing pipes 12 to backwash the filter screen 3, thereby removing the blockages in the filter screen holes;

[0039] Meanwhile, the water flow in the water storage plate 10 will also enter the interior of the water storage pipe 15 through the connecting pipe 16. Turn on the rotary motor 18, and the rotary motor 18 drives the baffle 20 to rotate through the rotary rod 19. The baffle 20 is also semicircular. When the baffle 20 rotates with the rotary rod 19, it can sequentially block the water inlet ends of the first drain pipe 171 and the second drain pipe 172. When the baffle 20 blocks the second drain pipe 172, the first drain pipe 171 is in a connected state. After the liquid passes through here, it enters the interior of the adjustment box 23, and then pushes the movable plate 24 upward, causing the rack 26 to move upward, driving the gear 27 to rotate. The gear 27 drives the driving bevel gear 29 to rotate through the connecting rod 28. The driving bevel gear 29 drives the driven bevel gear 31 to rotate. The driven bevel gear 31 drives the brush plate 33 to rotate through the cleaning column 32, thereby removing the blockages in the filter holes. As the rotary rod 19 continues to rotate, when the baffle 20 blocks the first drain pipe 171, the second drain pipe 172 is in a connected state. After the liquid passes through here, it then enters the water storage ring 38 through the drainage pipe 37 and finally sprays out from the flushing inclined pipe 40 to flush the dirt attached to the surface of the cleaning column 32. At this time, the sewage discharge pipe 41 and the water outlet pipe 4 can both be opened, and then the sewage is discharged, playing the function of automatic cleaning and anti-blocking, without the need for frequent manual disassembly and cleaning, and the use is simpler.

[0040] 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
