DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0033] Reference Figure 1-10 , an electro-Fenton coupled ultrafiltration membrane high-efficiency sewage treatment system, comprising a support frame 1 and a purification box 2 arranged on the support frame 1, the upper end surface of the purification box 2 is provided with a water inlet 3, and the right side is provided with a water outlet 4, a filter box 5 is arranged inside the purification box 2, and the bottom surface of the filter box 5 is provided with a stirring fan blade 7 driven by a motor 6, and the lower end of the stirring fan blade 7 is provided with a deceleration component 8, and a plurality of filter components 9 are opened on the side of the filter box 5, and the outer surface of the filter component 9 is connected with a blowing component 10 and is located inside the purification box 2, and the water outlet 4 is connected with the electrolysis component 11.

[0034] It is worth mentioning that the device is used to filter out particulate impurities contained in sewage, and then the organic sewage is oxidized into inorganic substances such as carbon dioxide and water by the electrolytic component 11.

[0035] Reference Figure 2 The outer surface of the filter box 5 is provided with a plurality of oblique angle grooves 51, and the grooves 51 are composed of the filter assembly 9 and the inclined surface b52.

[0036] In this embodiment, by the rotation of the stirring blades 7, under the action of centrifugal force, the sewage impacts in the direction of the filter assembly 9, thereby improving the filtering efficiency of the sewage.

[0037] Reference Figure 4-7 The filter assembly 9 includes a slide groove 91 arranged on the bottom surface, a filter plate 92 slidably arranged on the slide groove 91, a plurality of return springs 93 arranged on one side of the filter plate 92, cavities 94 respectively arranged on both sides of the filter plate 92, a support rod 95 fixedly connected to the inner surface of the filter plate 92, and an elastic sleeve 96 arranged at the end of the support rod 95.

[0038] It is worth mentioning that an elastic sleeve 96 is provided at the end of the support rod 95 . When the cam 83 is rotating, the elastic sleeve 96 can reduce the impact force of the cam 83 on the support rod 95 , thereby extending the service life of the support rod 95 .

[0039] Reference Figure 4-7 A brush 97 is fixedly disposed on the inner wall of the cavity 94 , and the brush 97 is located between the vent hole 102 and the filter plate 92 .

[0040] It is worth mentioning here that when the filter plate 92 moves left and right, the brush 97 can clean and drop large particles of impurities, so that the subsequent blowing component 10 can better clean the impurities.

[0041] Reference Figure 6 The blowing assembly 10 includes an air chamber 101 disposed on the outer side of the cavity 94, a plurality of vents 102 connecting the air chamber 101 and the cavity 94, and an air delivery pipe 103 connected to the air chamber 101. The diameter of the air inlet 104 of the vent 102 is greater than the diameter of the air outlet 105.

[0042] In this embodiment, the diameter of the air inlet 104 of the air vent 102 is larger than the diameter of the air outlet 105 , which can increase the flow rate of the gas entering and better impact the impurities on the filter plate 92 .

[0043] Reference Figure 8 The speed reduction assembly 8 includes a gear a81 arranged on the rotating shaft at the lower end of the stirring blade 7, a plurality of gears b82 meshing with the gear a81, and a cam 83 arranged on the outer side of the gear b82, and the inner teeth 84 on the cam 83 are all meshed with the gear b82.

[0044] In this embodiment, a speed reduction assembly 8 is provided on the rotating shaft of the stirring blade 7, and the speed reduction assembly 8 can avoid the impact force on the support rod 95 caused by the high-speed rotating lower cam 83, thereby extending the service life of the device.

[0045] Reference Figure 8-10The lower end surface of the cam 83 is provided with a plurality of rollers 85 , and the rollers 85 are slidably arranged in the arc groove 21 on the bottom surface of the purification box 2 .

[0046] It is worth mentioning here that by rolling with the help of the roller 85, the friction of the cam 83 on the bottom surface of the purification box 2 can be reduced, thereby reducing the loss of the device.

[0047] The working process is as follows:

[0048] Start the motor 6 to drive the stirring blade 7 to rotate at high speed. The sewage diffuses and impacts the surrounding side of the filter box under the action of centrifugal force. At the same time, the gear a81 on the stirring blade 7, the gear b82 meshing with the gear a81, and the cam 83 all rotate synchronously. The protrusion on the cam 83 squeezes the elastic sleeve 96 on the support rod 95, driving the filter plate 92 to move. Under the action of the reset spring 93, the filter plate 92 is reset and repeats the movement in the chute 91. The air chamber 101 is connected to the cavity 94 through the vent 102. The gas input through the gas pipe 103 cleans the impurities on the filter plate 92 through the vent 102.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
