Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically to a three-dimensional multi-stage water filtration device. Background Technology

[0002] With the expansion of industrial production, the widespread use of chemical fertilizers and pesticides in agriculture, and the increase in domestic sewage discharge, water pollution is becoming increasingly serious worldwide. Water not only contains conventional impurities such as sediment and suspended particles, but also often contains complex pollutants such as heavy metal ions, persistent organic pollutants, and pathogenic microorganisms, posing a serious threat to human health and the ecological environment. Against this backdrop, water filtration equipment, as a core device for removing pollutants and improving water quality, has become an indispensable key device in scenarios such as ensuring safe drinking water for households, meeting water quality standards for industrial production, municipal sewage treatment, and emergency water supply. Consequently, market demands for its performance are constantly increasing.

[0003] In existing water filtration equipment, multi-stage filtration is typically achieved using multiple filter plates. During the filtration process, solid impurities in the water are trapped on the filter plates, thus separating the impurities. However, as the filtration process continues, the amount of impurities trapped on the filter plates gradually increases, causing the filter pores to become clogged. This leads to a significant decrease in filtration efficiency, and may even prevent further filtration. Utility Model Content

After impurities accumulate on the filter plate 6, the first housing cover 2 can be disassembled by rotating the bolts, so as to facilitate the removal of the filter plate 6 from the housing 1 and the cleaning of the impurities attached to the filter plate 6, or even the replacement of the filter plate 6.

[0018] Reference Figure 2 and Figure 3The second positioning mechanism includes a positioning ring 11 and a support cover 12. The positioning ring 11 is connected to the bottom side wall of the flow guide chamber 7. The filter cartridge 8 is fitted on the outer wall of the positioning ring 11.

Specifically, clean water can be supplied into the second housing 15 through the water inlet pipe 17, and then the filter cartridge 8 is backwashed through the nozzle 16. The backwashed liquid can be discharged through the discharge pipe 18 to ensure the filtration effect of the filter cartridge 8.

[0020] Reference Figure 2 and Figure 3The second rotating mechanism includes a discharge pipe 18, a first cavity, a first gear ring 19, a first gear 20, and a first motor 21. The discharge pipe 18 is fixedly and connected to the bottom side wall of the support cover 12. The discharge pipe 18 has a built-in discharge control valve. The discharge pipe 18 passes through the second cover 3 and is rotatably sealed to the second cover 3. The first cavity is opened inside the second cover 3, and the discharge pipe 18 passes through the first cavity. The first gear ring 19 is fixedly installed on the outer wall of the discharge pipe 18. The first gear 20 is rotatably installed in the first cavity.

Nine-phase meshing, the first motor 21 is mounted on the second cover 3, and the output end of the first motor 21 is fixedly connected to the first gear 20. Specifically, the operation of the first motor 21 can drive the first gear 20 to rotate, and at the same time, the meshing of the first gear 20 with the first gear ring 19 drives the discharge pipe 18 and the support cover 12 to rotate. At the same time, the friction between the support cover 12 and the filter cylinder 8 drives the filter cylinder 8 to rotate. In addition, it should be noted that multiple balls are rotatably arranged on the bottom side wall of the flow guide chamber 7, and the top side wall of the filter cylinder 8 abuts against the balls.

[0021] Reference Figure 3 and Figure 4 The first rotating mechanism includes a second gear ring 22, a second gear 23, and a second motor 24. The second gear ring 22 is fixedly mounted on the outer wall of the backwash pipe 14. The second gear 23 is rotatably mounted inside the first housing 13 and meshes with the second gear ring 22. The second motor 24 is mounted on the side wall of the housing 1, and the output end of the second motor 24 is fixedly connected to the second gear 23. Specifically, the operation of the second motor 24 can drive the second gear 23 to rotate. At the same time, the meshing of the second gear 23 with the second gear ring 22 drives the backwash pipe 14 to rotate. In turn, the rotation of the backwash pipe 14 drives the second housing 15 and the nozzle 16 to move around the backwash pipe 14, thereby facilitating backwashing at different positions of the filter cartridge 8 and improving the backwashing effect.

[0022] In this embodiment, during use, the operator inserts the filter plate 6 into the housing 1 so that it rests on the fixed frame 9. Then, the first housing cover 2 is installed by rotating the bolts. The filter plate 6 is then fixed in place by the cooperation of the fixed frame 9 and the positioning post 10. Next, the operator inserts the filter cylinder 8 into the support cover 12 and fixes it to the housing 1 with bolts using the second housing cover 3. This allows the filter cylinder 8 to be fitted onto the positioning ring 11 and abut against the ball bearings. The operator then adds the water to be filtered into the housing 1 through the feed hopper, achieving graded filtration through the filter plate 6 and the filter cylinder 8. The filtered water is discharged through the drain outlet 4. After filtration, the operator closes the drain control valve and opens the impurity discharge control valve, while simultaneously supplying water to the second housing 15 through the inlet pipe 17. Clean water is supplied into the filter cartridge 8, and then the filter cartridge 8 is backwashed through the nozzle 16. During the backwashing process, the operator controls the first motor 21 and the second motor 24. The operation of the first motor 21 drives the first gear 20 to rotate. At the same time, the meshing of the first gear 20 with the first gear ring 19 drives the discharge pipe 18 and the support cover 12 to rotate. Simultaneously, the friction between the support cover 12 and the filter cartridge 8 drives the filter cartridge 8 to rotate. At the same time, the operation of the second motor 24 drives the second gear 23 to rotate. Simultaneously, the meshing of the second gear 23 with the second gear ring 22 drives the backwash pipe 14 to rotate. In turn, the rotation of the backwash pipe 14 drives the second housing 15 and the nozzle 16 to move around the backwash pipe 14, thereby facilitating backwashing of different positions of the filter cartridge 8 and improving the backwashing effect.
