Description

Technical Field

[0001] The utility model relates to the technical field of circulating water pumps, in particular to a multi-stage filtering device for a circulating water pump. Background Art

[0002] A circulating water pump is a pump used to transport circulating liquid for reaction, absorption, separation, and absorption liquid regeneration. Its function is to circulate the liquid in the device to maintain the normal operation of the system. Since the transported liquid often contains impurities and garbage, in order to prevent impurities and garbage from entering the circulating water pump and affecting the normal operation of the circulating water pump, it is often necessary to install a multi-stage filter device at the water inlet pipe of the water pump.

[0003] After searching, the patent publication number CN219663043U discloses a circulating water pump multi-stage filtering mechanism and a circulating water pump, wherein the circulating water pump multi-stage filtering mechanism comprises: a shell assembly; a filtering assembly arranged inside the shell assembly; and a vortex module arranged at the front end of the filtering assembly; wherein the filtering assembly comprises a front filtering module located in the middle section of the shell assembly and a rear filtering module located at the end of the shell assembly; the turbulence formed after the water flows through the vortex module arranged at the front end of the filtering assembly impacts the filtering assembly, and the impurities on the filtering assembly naturally fall into the collecting module arranged below the filtering assembly under the impact, and the front end of the circulating water pump is connected with the circulating water pump multi-stage filtering mechanism, and the vortex impact filtering assembly generated by the utility model reduces the accumulation of impurities on the filter net of the filtering assembly, collects and aggregates the impurities, reduces the residue inside the pipeline, reduces the inner loop resistance of the circulating water pump, and improves the working efficiency of the circulating water pump.

[0004] However, this patent still has some shortcomings. This patent does not have a structure for automatically cleaning the filter, and since multiple filters are installed inside the shell assembly, it is difficult to disassemble and clean them. During long-term use, as garbage and impurities continue to adhere to the mesh of the filter, it is easy to block the flow of water, thereby affecting the delivery efficiency of the circulating water pump.

[0005] For this purpose, we propose a multi-stage filtration device for a circulating water pump. Utility Model Content

[0028] The top of the filter box 1 is rotatably connected to two limit rods 13, and the limit frames 11 are fixedly installed on the left sides of the two limit rods 13 on the filter box 1. The bottom ends of the two limit rods 13 are against the top ends of multiple card seats 19, and the left ends of the two limit rods 13 are respectively connected to the corresponding limit frames 11. The card seats 19 can be limited by the limit rods 13. The bottom ends of multiple top rods 23 extend out of the card seats 19 and against the bottom ends of the card slots 20. This design is conducive to the use of the device. The right end of the transmission rod 9 is fixedly installed with a driven gear 16, and the bottom end of the driven gear 16 is meshed and connected with a driving gear 18. The design is conducive to the use of the equipment. The right side of the filter box 1 is located on the outside of the driving gear 18 and is sleeved with a bracket 15. A motor 17 is fixedly installed in the bracket 15. The output end of the motor 17 is fixedly installed on the driving gear 18. The driving gear 18 is driven to rotate by the motor 17, which is conducive to the use of the equipment. An inlet pipe 2 is fixedly installed on the left side of the filter box 1, and an outlet pipe 3 is fixedly installed on the right side of the filter box 1.

The sewage pipe 7 is convenient for discharging garbage and impurities after scraping and cleaning.

[0029] It should be noted that the utility model is a multi-stage filtering device for a circulating water pump. When in use, the water inlet end of the circulating water pump is connected to the water outlet pipe 3 of the water inlet pipe 2 of the device, and the water inlet pipe 2 is connected to the water outlet pipe of the water tank or the pool. During the operation of the circulating water pump, the water flows through multiple filter plates 12 for filtration, which can prevent garbage and impurities carried in the water source from entering the circulating water pump and affecting the normal operation of the circulating water pump. At the same time, the PLC controller 4 will regularly turn on the switch of the motor 17, and the motor 17 will drive the driving gear 18, the driven gear 16 and the transmission rod 9 to rotate 180 degrees, so that the rotating plate 10 can drive the scraper 14 to quickly scrape off the garbage and impurities attached to the multiple filter plates 12 and fall into the filter box 1 below the partition 5 through the installation groove 8, so as to avoid clogging by garbage and impurities. The mesh holes on the filter plate 12 affect the conveying efficiency of the circulating water pump. When cleaning, the garbage impurities can be quickly discharged by directly opening the drain pipe 7. When the filter plate 12 needs to be replaced, the two limit rods 13 can be rotated toward the side away from each other, so that the limit rods 13 no longer block the holder 19. At this time, the spring 21 drives the slide plate 22 to return to its position, so that the top rod 23 extends downward out of the holder 19, that is, the top of the filter plate 12 extends out of the slot 6, which is convenient for the staff to take it away. The multi-stage filtering device of this circulating water pump is easy to use. Through the above-mentioned components, the garbage impurities attached to the filter plate 12 can be automatically cleaned regularly to avoid the garbage impurities clogging the mesh holes on the filter plate 12 and affecting the conveying efficiency of the circulating water pump. At the same time, the filter plate 12 is easy to disassemble and assemble, which is conducive to the subsequent replacement of the filter plate 12.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
