Description

Technical Field

[0001] This application relates to the field of pump, valve, and pipeline equipment technology, and in particular to an impurity filtration structure for pump, valve, and pipeline systems. Background Technology

[0002] In pump and valve pipeline systems, the transported liquids often contain various impurities. If these impurities are not filtered in time, they can cause serious damage to the pumps, valves, and pipelines. Currently, existing impurity filtration devices for pumps and valve pipelines have many shortcomings. Some traditional filtration devices use fixed filter screens. Once the filter screen becomes clogged, the system needs to be shut down for cleaning or replacement. This not only affects the continuity of production, but also makes cleaning and replacing the filter screen cumbersome, consuming a lot of time and manpower. Some filtration devices with replaceable filter screens cannot prevent impurities from falling back into the pipeline during filter screen replacement, re-contaminating the transported liquid. Furthermore, sealing is difficult to guarantee during replacement, making leakage prone to occur. In addition, existing filtration devices are not structurally reasonable, are large in size, occupy a lot of space, and are not suitable for installation and use in space-constrained locations.

[0003] Chinese patent application number 2020216528174 discloses an impurity filtration structure for pump and valve pipelines, including a pipeline body and a filter assembly. The pipeline body includes a pipe body and a connecting block at the upper end of the pipe body. The filter assembly longitudinally penetrates the connecting block and is embedded inside the pipe body. The filter assembly includes a cover plate and a fixing block at the lower end of the cover plate. A filter groove is transversely formed inside the fixing block. A baffle is fixed to the lower edge of one side of the filter groove, and a filter screen is obliquely installed on the other side of the filter groove. The pipe body also includes a pipeline through groove. In this impurity filtration structure for pump and valve pipelines, the filter assembly has a combined longitudinal section of a fixed baffle and a filter screen with a "V" shaped structure.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: the aforementioned patents do not allow for quick filter replacement. Utility Model Content

Through-holes for the filter screens to pass through are provided on the placement plate and the sealing plate. A removable sealing strip is installed in each through-hole. Baffles for fixing the sealing strip are provided on both the placement plate and the sealing plate.

[0007] Optionally, the filter tube has tracks on its two opposite inner walls for limiting the movement of the filter screen. The tracks include an upper track and a lower track with the same structure. Rollers are provided on the opposite surfaces of the upper track and the lower track. There are multiple rollers and they are evenly spaced along the length of the track. The surface of the rollers is provided with a rubber layer.

[0008] Optionally, both the placement compartment and the storage compartment have an opening on one side wall for the filter to pass through, and the placement plate and the sealing plate are provided with a rotating roller for changing the direction of the filter.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses an impurity filtration structure for pump and valve pipelines. For example... Figure 1 and 2As shown, the device includes a pipe body for conveying liquid, with a vertically aligned filter tube 1 connected to the pipe body. The filter tube 1 has a rectangular tubular structure. Two through holes 2 are provided on opposite sides of the filter tube 1, penetrating its thickness direction. A placement plate 3 for sealing is screwed into one through hole 2, and a sealing ring is bonded to the placement plate 3. A storage compartment 4 for holding unused filter screens is bolted to the side of the placement plate 3 away from the through hole 2. A sealing plate 5 for sealing the through hole 2 is bolted into the other through hole 2, and a sealing ring is bonded to the sealing plate 5. A storage compartment 6 for storing used filter screens is bolted to the side of the sealing plate 5 away from the through hole 2. A winding reel for winding and storing the filter screen is rotatably connected inside the placement compartment 4 and the storage compartment 6. The winding reel is existing technology. A torsion spring, also existing technology, is installed on the inner wall of the placement compartment 4 to cooperate with the winding reel. A handle extending into the storage compartment 6 and engaging with the winding reel is rotatably connected to the storage compartment 6. Rotating the handle winds the filter screen onto the winding reel inside the storage compartment 6. The placement plate 3 and the sealing plate 5 have through-holes 7 for the filter screen to pass through. A removable sealing strip 8 is installed inside the through-holes 7. A baffle 9 for fixing the sealing strip 8 is screwed onto the placement plate 3 and the sealing plate 5. The sealing strip 8 has a trapezoidal cross-section, and a positioning groove 16 for placing the baffle 9 is located in the middle of the sealing strip 8. The baffle 9 has a "U" shaped structure. The filter tube 1 has tracks on its two opposing inner walls to limit the movement of the filter screen. The tracks include an upper track 10 and a lower track 11 with identical structures. Both the upper track 10 and the lower track 11 are fixed to the inner wall of the filter tube 1 with screws. Multiple support rods are evenly spaced on the opposite surfaces of the upper track 10 and the lower track 11 and connected by screws. The support rods are arranged in pairs, and rollers 12 are rotatably connected to the ends of the two support rods away from the tracks. The support rods are arranged along the length of the tracks, and the surface of the rollers 12 is bonded with a rubber layer.

[0022] In one embodiment, according to the appendix Figure 2 As shown, both the placement compartment 4 and the storage compartment 6 have openings 13 on one side wall for the filter screen to pass through. Support rods are bolted to the placement plate 3 and the sealing plate 5. The support rods are arranged in pairs, and one end of each support rod is connected to a rotating roller 14 for changing the direction of the filter screen. A cover 15 that can cover the through opening 7 is rotatably connected to the placement compartment 4 and the storage compartment 6 near the opening 13. The cover 15 has an "L" shaped cross-section.

[0023] In one embodiment, according to the appendix Figure 3 and 4 As shown, the filter tube 1 is provided with a receiving plate 17 that can extend from one through port 7 to another through port 7. The receiving plate 17 has a rectangular structure suitable for the cross-section of the filter tube 1. The receiving plate 17 is connected to the outer wall of the filter tube 1 by a pull rope. The four sides of the receiving plate 17 are glued with retaining rings 18.

[0024] The implementation principle of the impurity filtration structure for a pump valve pipeline according to an embodiment of this application is as follows: One end of the unused filter screen is removed from the winding reel of the placement chamber 4. The filter screen passes through the through-hole 7 of the placement plate 3, then through the through-hole 7 of the sealing plate 5, and enters the storage chamber 6, where it is fixed to the winding reel. The sealing strip 8 and baffle 9 are installed, and the covers 15 on the placement chamber 4 and storage chamber 6 are closed to ensure the device is sealed. When the filter screen becomes clogged and needs replacement, the covers 15 on the placement chamber 4 and storage chamber 6 are opened, and the sealing strip 8 and baffle 9 are removed. The handle on the storage chamber 6 is slowly rotated to wind up the used filter screen. Simultaneously, the torsion spring inside the placement chamber 4 drives the winding reel to rotate, releasing the new filter screen. During the movement of the filter screen, the receiving plate 17 is inserted through the through-hole 7 on one side of the filter tube 1 via a pull rope, positioning it below the filter screen to catch impurities falling from it.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
