Description

Technical Field

[0001] The utility model relates to the technical field of circulating pumps, in particular to a filter screen structure for an inlet of a pipeline circulating pump. Background Art

[0002] A pipeline circulation pump is a device used to circulate fluids within a pipeline system. During the fluid transfer process, the pump must filter the fluid as it contains impurities. The filtered impurities often adhere to the filter screen, leaving little room for them to be stored. However, to prevent fluid leakage, the pump is typically tightly connected to the pipeline, making it difficult to clean the filtered impurities. This can easily lead to pipeline blockage and affect the normal circulation of the fluid. To address this issue, we propose a filter screen structure for the inlet of a pipeline circulation pump. Summary of the Invention

[0003] The main purpose of the utility model is to provide a filter structure for the inlet of a pipeline circulation pump to overcome the problems mentioned in the above background technology.

[0023] See also Figure 1-Figure 5 As shown, a filter screen structure for the inlet of a pipeline circulation pump includes a pump body 1, a junction box 101 is fixedly provided at the middle of the front end of the outer surface of the pump body 1, a fan cover 102 is fixedly provided on the upper surface of the pump body 1, and a base 103 is fixedly installed on the lower surface of the pump body 1. A water inlet 2 and a water outlet 3 are fixedly provided at the lower part of both sides of the outer surface of the pump body 1, and a filter cartridge 4 is fixedly provided between the water inlet 2 and the water outlet 3 and the ends close to the pump body 1.

[0024] A cleaning port is provided in the middle of the lower surface of the filter cartridge 4, and a locking ring 401 is fixedly installed on the inner surface of the cleaning port through the filter cartridge 4. Connecting ears 402 are fixedly provided at both ends of the locking ring 401 and in the middle of both sides of the outer surface of the filter cartridge 4. A locking bolt 403 is screwed through and fixedly installed on the upper surface of the connecting ear 402. The middle part of the inner bottom surface of the filter cartridge 4 is movably covered with a semi-arc-shaped sealing ring 501. Both ends of the outer surface of the sealing ring 501 are fixed with a limiting ring 5. Both ends of the middle part of the inner surface of the filter cartridge 4 are provided with a limiting groove 404, and the limiting ring 5 is embedded in the limiting groove 404.

[0025] A funnel-shaped filter disc 6 is fixedly mounted on one end of the inner surface of the filter cartridge 4, and a number of filter holes are evenly provided on the outer surface of the filter disc 6. A funnel-shaped separation disc 7 is fixedly mounted on the other end of the inner surface of the filter cartridge 4, and a flow port is provided in the middle of one end of the separation disc 7 close to the filter disc 6. Partitions 701 are movably mounted on the upper and lower parts of the inner surface of the separation disc 7 through the flow port, and a spring hinge 702 is fixedly mounted on the outer surface of the partition 701 close to one end of the filter disc 6, and the other end of the spring hinge 702 is connected to the outer surface of one end of the separation disc 7 close to the filter disc 6.

[0026] When the present invention is in use, the pump body 1 can be started first to perform normal operation. During the operation of the pump body 1, the fluid in the pipe connected to the water inlet 2 will begin to circulate toward the pump body 1. At this time, the fluid can flow into the filter cartridge 4 and push the partition 701 toward the direction of the pump body 1. When the partition 701 is in the pushed-open state, the spring hinge 702 can be in a reverse elastic force state. At this time, the fluid can contact the filter disc 6 to filter impurities when the partition 701 is pushed open, and the filtered fluid can flow into the pump body 1. At this time, the fluid entering the pump body 1 can circulate toward the water outlet 3 under the action of the pump body 1 and start circulation. In this case, the fluid will contact the partition 701 provided at the water outlet 3 again, and push the partition 701 open to contact the filter disc 6 at the water outlet 3 for secondary filtration of impurities. At this time, the fluid that has been secondary filtered can be discharged through the water outlet 3.

[0027] Secondly, when the fluid stops flowing, the thrust exerted on the partition 701 disappears. At this time, the spring hinge 702, which is in a reverse elastic stress state, begins to reset under the action of the elastic force, thereby controlling the partition 701 to close. In this case, the contact between the fluid in the pipeline and the filter disc 6 is cut off, thereby preventing the impurities filtered by the filter disc 6 from flowing back along with the fluid. At the same time, the impurities filtered by the filter disc 6 will be stored in the gap between the filter disc 6 and the separation disc 7.

[0028] Finally, the locking bolt 403 can be turned counterclockwise to disengage it from the connecting ear 402. At this time, the locking ring 401 can be separated from the filter cartridge 4 to expose the cleaning port opened in the middle of the lower surface of the filter cartridge 4. When the cleaning port is exposed, the sealing ring 501 set in the middle of the bottom surface of the filter cartridge 4 can be moved through the cleaning port. When the sealing ring 501 is rotated to the middle of the top surface of the filter cartridge 4, the cleaning port will be fully opened. At this time, the impurities in the filter cartridge 4 can be cleaned through the cleaning port, thereby avoiding the blockage problem caused by the inconvenience of cleaning impurities. After the impurities are cleaned, the sealing ring 501 is reset to its original position, and the cleaning port can be re-locked and sealed using the locking ring 401.

[0029] The above are merely examples of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
