[0002] With the continuous development of industrial production, water resources are becoming increasingly scarce. In order to save water and reduce production costs, the application of circulating water treatment equipment is becoming more and more extensive; circulating water treatment equipment can recycle industrial water, greatly reducing the use of fresh water, thereby reducing production costs. This is of great significance to areas with scarce water resources.

[0003] Circulating water filtration equipment is one of the most commonly used equipment in circulating water treatment. During the use of existing energy-saving circulating water filtration equipment, the staff generally cleans the filter regularly, but cannot clean and collect the larger particles of impurities filtered out in time. This will cause the filter to be frequently blocked even if the filter is cleaned regularly, thereby affecting the filtering effect of circulating water. For this reason, energy-saving circulating water filtration equipment is proposed. Utility Model Content

[0023] like Figures 1 to 4As shown, the energy-saving circulating water filtering equipment includes a filter box 1, which is a rectangular box 7 with a hollow interior and a hollow bottom of the filter box 1. A water inlet 2 is provided on the top of the filter box 1. A servo motor 3 is fixedly installed on the rear outer wall of the filter box 1. The output end of the servo motor 3 extends to the interior of the filter box 1 and is fixedly connected to a rotating shaft 4. Four evenly distributed filter screens 5 are fixedly installed on the side wall of the rotating shaft 4. A cleaning rake 6 is arranged inside the filter box 1. A rectangular box 7 is inlaid and installed on the right wall of the filter box 1. A driving component 8 for driving the cleaning rake 6 to move is arranged inside the rectangular box 7. A mesh box 9 is arranged inside the filter box 1. A filter screen 10 is arranged inside the filter box 1. A drainage funnel 1 is fixedly installed at the bottom of the filter box 1. 1. It should be noted that when water is injected into the interior of the filter box 1 from the water inlet 2, the servo motor 3 drives the rotating shaft 4 and the four filter screens 5 to rotate at the same time. The four filter screens 5 can initially filter out large particles of impurities in the water during the rotation process. When each filter screen 5 rotates to the side close to the rectangular box 7, the cleaning rake 6 is driven by the driving component 8 to scrape the impurities on the surface of the filter screen 5 into the net box 9. Since each filter screen 5 is in a state of continuous filtering and cleaning, the filter screen 5 will not be frequently blocked. It is only necessary to regularly remove and clean the impurities inside the net box 9. The water filtered by the filter screen 5 continues to fall, and then is filtered again through the filter screen 2 10, and finally the filtered water is discharged through the drainage funnel 11.

[0024] like Figure 1 , Figure 2 As shown, the driving assembly 8 includes a servo motor 801, and the servo motor 801 is fixedly installed on the rear outer wall of the filter box 1.

The output end of the electric telescopic rod 803 passes through the strip hole 804 and is fixedly connected to the cleaning rake 6. It should be noted that the servo motor 801 can drive the rotating shaft 802, the electric telescopic rod 803, and the cleaning rake 6 to rotate, so that the cleaning rake 6 rotates to a suitable angle. The extension and retraction of the electric telescopic rod 803 can drive the cleaning rake 6 to move back and forth, thereby not affecting the rotation of the filter 5 and the cleaning of impurities.

[0025] like Figure 2 , Figure 3As shown, a window 12 is provided on the rear wall of the filter box 1, and a reversible box door 13 is movably installed inside the window 12. Two U-shaped rods 14 are fixedly installed on the rear inner wall of the filter box 1, and a positioning rod 15 is fixedly installed inside each U-shaped rod 14. The two positioning rods 15 are fixedly installed on the bottom of the net box 9.

[0027] like Figure 1 , Figure 2 As shown, an L-shaped connecting rod 20 is fixedly installed on the inner side wall of the water inlet 2, and a dispersion cone 21 is fixedly installed on the vertical end of the connecting rod 20. It should be noted that the dispersion cone 21 can disperse the water flow and effectively filter the water.

[0028] like Figure 1 As shown, each filter screen 15 is fixedly installed with a filter screen 3 22 at one end away from the rotating shaft 1 4, and a guide block 23 is fixedly installed on the inner left wall of the filter box 1. It should be noted that the filter screen 3 22 can prevent impurities on the filter screen 1 5 from falling off when the filter screen 1 5 rotates, and the guide block 23 can prevent part of the water flow from not being filtered by the filter screen 1 5.

[0029] In summary:

[0030] When water is injected into the interior of the filter box 1 from the water inlet 2, the servo motor 3 drives the rotating shaft 4 and the four filter screens 5 to rotate at the same time. The four filter screens 5 can initially filter out large particles of impurities in the water during the rotation process. When each filter screen 5 rotates to the side close to the rectangular box 7, the driving component 8 drives the cleaning rake 6 to scrape the impurities on the surface of the filter screen 5 into the net box 9. Since each filter screen 5 is in a state of continuous filtering and cleaning, the filter screen 5 will not be frequently blocked. It is only necessary to regularly remove and clean the impurities inside the net box 9. The water filtered by the filter screen 5 continues to fall, and then is filtered again through the filter screen 2 10, and finally the filtered water is discharged through the drainage funnel 11.
