Most activated carbon filters filter slowly and are difficult to filter large quantities of treated water quickly. In addition, insufficient filtration cannot increase the contact time and area between water and the filter device, resulting in low work efficiency. Moreover, many activated carbon filters lack pre-filtration equipment for the input treated water during use. In the long run, it is easy to cause the problem of clogging the activated carbon material, reducing the working cycle of the activated carbon filter bed. Utility Model Content

[0021] Example

[0022] like Figure 1 As shown, a high-efficiency activated carbon filter includes a filter body 1, a water inlet 2 is provided on one side of the top of the filter body 1, a water outlet 3 is provided at the bottom of the filter body 1, and a plurality of first activated carbon filter beds 4 are provided inside the filter body 1. When treated water enters the filter body 1 through the water inlet 2, the treated water is subjected to adsorption, precipitation and filtration by the three first activated carbon filter beds 4, and then the treated water is discharged from the filter body 1 through the water outlet 3.

[0023] The first activated carbon filter bed 4 is provided with through holes on the side away from the water inlet 2, and a water pump 5 is provided at the bottom of the filter body 1. The output end of the water pump 5 is connected to a circulation pipe 6 matching the through hole. The circulation pipe 6 passes through the through hole, and the water outlet end thereof is at the same height as the water inlet 2. When the treated water flows to the bottom of the filter body 1 through the first activated carbon filter bed 4, the water pump 5 is started to pass the treated water through the circulation pipe 6 and pass through the first activated carbon filter bed 4 again for adsorption, precipitation and filtration, thereby increasing the contact time and area between the water and the filter device, so that the treated water is fully filtered.

[0024] like Figure 2 As shown, a mounting frame 17 matching the bottom of the filter body 1 is provided at the bottom of the water pump 5, and the mounting frame 17 is fixedly connected to the bottom of the water pump 5 via a mounting platform 18. Through the interaction between the mounting frame 17 and the mounting platform 18, the water pump 5 can be fixed to the bottom of the filter body 1 without hindering the treated water from flowing out of the water outlet 3.

[0025] like Figure 3-4As shown, a first protective box 7 is provided on the top of the filter body 1, and a telescopic cylinder 8 is provided inside the first protective box 7. A pressure plug 9 matching the inner diameter of the filter body 1 is provided on the upper side of the water inlet 2 inside the filter body 1, and the top of the pressure plug 9 is movably connected to the output end of the telescopic cylinder 8 through a telescopic rod 10. When the treated water enters the filter body 1, the telescopic cylinder 8 is started, and the pressure plug 9 is moved up and down at the top of the filter body 1 through the telescopic rod 10, thereby increasing the filtration speed of the treated water, and realizing rapid and large-scale filtration of the treated water.

[0026] A rotating shaft 11 is provided in the first activated carbon filter bed 4, and the two ends of the rotating shaft 11 are respectively connected to the rotating hole on the inner wall of the filter body 1 and the motor 12. The bottom of the motor 12 is fixedly connected to the inner wall of the filter body 1, and a second protective box 13 is provided on the outer side of the motor 12. The end of the rotating shaft 11 close to the motor 12 passes through the second protective box 13 and is connected to the output end of the motor 12. After the filter treats the treated water for a period of time, the motor 12 is started, and the first activated carbon filter bed 4 is rotated at a certain angle through the rotating shaft 11, and the blockage on the first activated carbon filter bed 4 can be automatically cleaned by the gravity of the blockage, thereby increasing the service life of the first activated carbon filter bed 4.

[0027] A receiving plate 14 is provided at the bottom of the filter body 1 on the side away from the circulation pipe 6, and the bottom end of the receiving plate 14 is connected to the inner wall of the filter body 1 through the second activated carbon filter bed 15. When the blockage falls off on the first activated carbon filter bed 4 due to its own gravity, the blockage is collected on the second activated carbon filter bed 15 through the receiving plate 14, thereby realizing the collection of the fallen blockage.

[0028] A movable door 16 is provided on one side of the filter body 1 close to the second activated carbon filter bed 15, and the movable door 16 is movably connected to the filter body 1. When the second activated carbon filter bed 15 completes collecting the blockage, the blockage on the second activated carbon filter bed 15 can be cleaned in time through the movable door 16, thereby increasing the service life of the second activated carbon filter bed 15.

[0029] Therefore, the utility model adopts the above-mentioned high-efficiency activated carbon filter, which can quickly filter the treated water in large quantities, and increase the contact time and area between the water and the filtering device, so that the treated water is fully filtered, and can also automatically clean the blockage of the activated carbon filter bed, thereby increasing the service life of the activated carbon filter bed.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
