Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to small-scale water purification equipment. Background Technology

[0002] In the process of water treatment, the raw water first enters the micro-flocculation unit through lifting / gravity. The micro-flocculation unit automatically starts and stops according to the changes in the raw water quality. The micro-flocculated water flows by gravity to the ultrafiltration membrane filtration system unit, where it is filtered by siphon action. The filtered water is then disinfected by chlorination through the dosing system and enters the clear water tank for supply to users.

[0003] Between the micro-flocculation unit and the ultrafiltration membrane filtration system unit, the water needs to be coarsely filtered first. For example, the small integrated water purification equipment with announcement number CN219823800U filters the micro-flocculated water through a removable and replaceable filter screen, which can improve the service life of the ultrafiltration membrane filtration system unit and improve the water filtration efficiency.

[0004] However, the aforementioned patents still have shortcomings. The disassembly structure of the filter screen is relatively complex and difficult to operate manually. At the same time, cleaning impurities by disassembling the filter screen greatly increases the frequency of filter screen inspection and maintenance. Frequent operation will increase the labor intensity of staff, increase the cost of water treatment, and make it inconvenient for users.

[0005] To address the aforementioned problems, an improved small-scale water purification device is now designed. Utility Model Content

A cleaning rod 16 is installed on the side wall of the rotating block 14 for cleaning the impurities filtered at the upper end of the filter disc 12. The lower end of the cleaning rod 16 is in close contact with the upper end of the filter disc 12. A slag discharge assembly is provided on the side wall of the filter disc 12 for discharging the cleaned impurities.

[0028] The slag discharge assembly includes a conical filter plate 11, which is installed on the side wall of the filter disc 12. The lower end of the conical filter plate 11 is located on the inner wall of the filter tank 1. A second slag discharge port 5 is provided on the side wall of the filter tank 1 above the lower end of the conical filter plate 11 to facilitate the discharge of impurities.

[0033] The working principle of a small water purification device:

[0034] In use, the water treated by the micro-flocculation unit is transported to the filter tank 1 through the inlet pipe 8, and then coarsely filtered through the filter disc 12 and the conical filter plate 11. The filtered water is then transported to the ultrafiltration membrane filtration system unit through the outlet pipe 3.

[0035] At the same time, the motor 18 is started. The output end of the motor 18 drives the rotating block 14 to rotate. The rotating block 14 drives the cleaning rod 16 to rotate.
