Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a circulating water treatment device with a self-purification function. Background Art

[0002] Human daily life cannot do without water, and industrial production is also inseparable from water. With the development of industrial production, water consumption is increasing. Therefore, rational and economical water use has become an important issue in the development of industrial production. In order to save the use of water resources, water resources need to be recycled.

[0003] Among them, during the water circulation process, a filter cartridge is needed to filter impurities in the water. Impurities retained in the gaps of the filter cartridge will cause blockage and affect the filtering effect. Therefore, the impurities in the filter cartridge need to be cleaned regularly. The common cleaning method is: use water pressure to "backwash" the filter cartridge to flush out the impurities inside the filter cartridge. During actual use, since there is a large space between the filter cartridge and the filtering device, and the filter cartridge is only partially blocked, water can easily be discharged directly through the unblocked part of the filter cartridge, causing pressure relief, resulting in some impurities stuck in the gaps of the filter cartridge. It is not easy to separate from the filter cartridge due to insufficient water pressure.

[0004] To this end, we propose a circulating water treatment device with self-purification function. Summary of the invention

[0005] The purpose of the utility model is to provide a circulating water treatment device with a self-purification function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulating water treatment device with a self-cleaning function, comprising a filter tank body and a filter cartridge, the filter tank body being installed with the filter cartridge, a flushing assembly, the flushing assembly being used to flush impurities remaining on the inner wall of the filter cartridge, the flushing assembly being rotatably connected to the filter tank body, a cleaning assembly, the cleaning assembly being used to clean the inner wall of the filter tank body, and the cleaning assembly being installed in the flushing assembly.

[0007] Preferably, the flushing assembly includes a sealing cover, which is rotatably connected to the filter tank body, the sealing cover is fixedly connected to a flow guide pipe, a nozzle is installed in the flow guide pipe, the sealing cover is fixedly connected to a gear ring, the gear ring is meshingly connected to a gear, a transmission shaft is fixedly connected to the gear, a servo motor is provided on the transmission shaft, and the servo motor and the filter tank body are fixedly connected.

[0008] Preferably, the cleaning assembly comprises a screw rod, which is sleeve-connected to the cover, a nut is threadedly connected to the screw rod, a disc is fixedly connected to the screw rod, a vertical rod is fixedly connected to the disc, and a rubber scraper is fixedly connected to the vertical rod.

[0009] Preferably, a water outlet is fixedly connected in the filter tank.

[0010] Preferably, the filter cartridge is fixedly connected to a sewage discharge housing, the sewage discharge housing is fixedly connected to a clamping ring, bolts are installed in the clamping ring, and the clamping ring is connected to the filter tank body through the bolts.

[0011] Preferably, a sealing plug is installed in the sewage discharge housing.

[0012] Preferably, a water inlet pipe is fixedly connected to the sewage shell, and a flange is fixedly connected to the water inlet pipe.

[0013] Preferably, a control valve is installed in the water inlet pipe.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. The water source is sprayed toward the filter cartridge through the nozzle on the guide tube. The servo motor drives the transmission shaft to rotate through the coupling, and then the gear on the top of the transmission shaft drives the gear ring to rotate. When the gear ring drives the sealing cover to rotate in the filter tank through the sealing bearing, the sealing cover drives the guide tube to rotate along the outer ring of the filter cartridge, and the water source is sprayed into the gap of the filter cartridge through the nozzle, thereby flushing the filter cartridge.

[0016] The servo motor provides power for the rotation of the sealing cap, and the sealing cap drives the guide tube to reciprocate along the outer ring of the filter cartridge. Water is sprayed to the filter cartridge through the nozzle. An external water source is used, and the pressure of the water source is in a constant state to reduce the pressure relief. Under the action of the water source pressure, the impurities and the filter cartridge are forced to separate, thereby achieving a comprehensive flushing of the filter cartridge. In addition, a plurality of nozzles are arranged in the vertical direction of the guide tube. The use of the nozzles ensures the flushing effect of the filter cartridge. The impurities remaining on the filter cartridge can be flushed without removing the filter cartridge from the filter tank body, thereby ensuring the filtering effect of the filter cartridge.

[0017] 2. Pass the screw through the cover and the nut to connect them, and at the same time, the disc abuts against the inner side of the cover. When the cover rotates on the top of the filter tank, the rubber scraper on the outer wall of the vertical rod moves along the inner wall of the filter tank, and the rubber scraper is used to clean the inner wall of the filter tank.

[0018] Through the setting of the screw and the nut, the vertical rod can be disassembled, and then the rubber scraper on the vertical rod can be replaced. The setting of the rubber scraper can clean the inside of the filter tank. The use of the rubber scraper reduces the wear on the inner wall of the filter tank during the cleaning process, thereby ensuring the cleanliness of the inside of the filter tank.
