Description

Technical Field

[0001] This utility model relates to the field of multi-layer filtration anti-clogging technology for upper tower pump bodies, and in particular to a multi-layer filtration anti-clogging device for circulating water pipes of upper tower pump bodies. Background Technology

[0002] The multi-layer filtration and anti-clogging device for the circulating water pipe of the upper tower pump is mainly used for impurity filtration and anti-clogging in circulating water systems. It achieves efficient interception of suspended solids through a multi-layer filtration structure, while employing an automatic backwashing function to maintain filter layer cleanliness. The following are its core components and working principle: Multi-layer filtration structure: Includes a coarse filter layer (such as quartz sand, anthracite, etc.) and a fine filter layer (filter screen or filter media layer), removing suspended solids of different particle sizes through two-stage treatment. Modular design: Uses standard sand cylinder unit combinations, supporting vertical or horizontal installation, facilitating flexible adjustment of flow rate and floor space. Automatic backwashing system: Backwashing is triggered by a differential pressure sensor, using clean water to backwash the filter layer, reducing clogging and extending service life. Filtration: Water flows evenly to the filter layer through a distributor, suspended solids are intercepted by the media, and the filtered clean water is collected through a collector.

[0003] An existing multi-layer filter anti-clogging device for circulating water pipes in an upper tower pump body is prone to clogging after the pipeline is installed. Due to the length of the pipeline, impurities contained in the liquid can easily remain inside the pipeline, making it inconvenient for workers to install and disassemble the pipeline easily. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-layer filter anti-clogging device for the circulating water pipe of the upper tower pump body.

[0005] This utility model is achieved by the following technical solution: a multi-layer filter anti-clogging device for circulating water pipe of upper tower pump body, including a connecting pipe, a valve is fixedly connected inside the connecting pipe, a connecting collar is threaded to the right end of the connecting pipe, and an installation sleeve is threaded to the inner wall of the connecting collar. Both ends of the mounting sleeve are fixedly connected to limit springs. A pull handle is fixedly connected to the surface of the limit spring. A limit support is fixedly connected to the surface of the pull handle. A limit retaining ring is fixedly connected to the surface of the limit support. A sealing gasket is inserted into the inside of the mounting sleeve. A transparent branch tube is inserted into the inside of the mounting sleeve. An mounting ring is slidably connected to the surface of the transparent branch tube. A connecting plate is fixedly connected to the surface of the mounting ring.

[0006] As a further improvement to the above solution, the right end of the connecting pipe contacts the left end surface of the mounting sleeve, and the number of the limiting support pillars is set to two, with the two limiting support pillars symmetrically distributed vertically around the mounting sleeve.

[0007] Through the above technical solution, the connecting collar is tightly engaged with the right end of the connecting pipe through threads to form an anti-loosening structure. The installation sleeve serves as the core filter chamber, and its inner and outer walls are equipped with precision-machined threaded interfaces, which not only ensures reliable connection with upstream and downstream pipelines, but also provides a standardized installation benchmark for internal filter elements. This segmented design allows the filter unit to be disassembled and maintained independently without shutting down the entire circulation system.

[0008] As a further improvement to the above solution, the surface of the limiting ring contacts the inner wall surface of the mounting sleeve, and the surface of the limiting ring contacts the inner wall surface of the sealing gasket.

[0009] As a further improvement to the above solution, the surface of the sealing gasket is in contact with the inner wall surface of the transparent branch pipe, the connecting plate is inserted into the inside of the mounting sleeve, and the surface of the connecting plate is in contact with the surface of the limiting ring.

[0010] As a further improvement to the above scheme, the number of limiting springs is set to four, and two springs are arranged in a group. The four limiting springs are symmetrically distributed vertically around the mounting sleeve.

[0011] Through the above technical solution, four symmetrically distributed limiting springs form an elastic support network with the mounting sleeve as the center. When water flow carries impurities and impacts the filter structure, the spring group can absorb the instantaneous impact force and generate periodic vibration. The pull handle serves as a manual intervention interface, and the operator can enhance the vibration effect by pulling outward. Combined with the self-resetting characteristic of the spring, it achieves a combination of physical anti-clogging and active sludge removal, which significantly improves the filtration efficiency compared to static filters and effectively delays the clogging cycle.

[0012] As a further improvement to the above solution, the number of connecting plates is set to four, and the four connecting plates are equidistantly distributed around the mounting sleeve, with the surface of the transparent branch pipe in contact with the surface of the limiting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model establishes a visual sealed filtration system by setting a sealing gasket and a transparent branch pipe. The transparent branch pipe serves as an observation window to display the internal filtration status in real time, allowing operators to promptly determine when to clean. By setting a limiting support as a guide rail, the limiting ring is ensured to be accurately positioned within the installation sleeve. Furthermore, the connection plate and installation ring ensure convenient installation when connecting and fixing the transparent branch pipe.

[0014] This utility model forms a three-point positioning mechanism by setting a double contact design between the surface of the retaining ring, the inner wall of the mounting sleeve, and the sealing gasket. This fixes the axial position of the filter element and prevents displacement through radial constraint. The sliding connection design of the mounting ring allows the filtration area to be increased or decreased as needed. Combined with the quick-plug structure of the connecting plate, the equipment can adapt to different working conditions from coarse filtration to fine filtration. Attached Figure Description

An installation ring 11 is slidably connected to the surface of the transparent branch tube 10. A connecting plate 12 is fixedly connected to the surface of the installation ring 11.

[0020] The connecting collar 3 is tightly engaged with the right end of the connecting pipe 1 through threads to form an anti-loosening structure. The mounting sleeve 4 serves as the core filter chamber, with precision-machined threaded interfaces on both its inner and outer walls. This ensures reliable connection with upstream and downstream pipelines and provides a standardized installation benchmark for the internal filter elements.

By setting the double contact design between the surface of the ring and the inner wall of the mounting sleeve 4 and the sealing gasket 9, a three-point positioning mechanism is formed, which not only fixes the axial position of the filter element, but also prevents displacement through radial constraint.

[0024] Four symmetrically distributed limiting springs 5 ​​form an elastic support network with the mounting sleeve 4 as the center. When water carrying impurities impacts the filter structure, the spring group can absorb the instantaneous impact force and generate periodic vibration. The pull handle 6 serves as a manual intervention interface. Operators can enhance the vibration effect by pulling outward. Combined with the self-resetting characteristics of the springs, it achieves a combination of physical anti-clogging and active sludge removal, which significantly improves the filtration efficiency compared to static filters and effectively delays the clogging cycle.

By setting a double contact design between the surface of the limiting ring 8 and the inner wall of the mounting sleeve 4 and the sealing gasket 9, a three-point positioning mechanism is formed, which not only fixes the axial position of the filter element, but also prevents displacement through radial constraint. By setting a sliding connection design of the mounting ring 11, the filtration area can be increased or decreased as needed. With the quick insertion and removal structure of the connecting plate 12, the equipment can adapt to different working conditions from coarse filtration to fine filtration.
