Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater filtration device for environmental remediation. Background Technology

[0002] Wastewater treatment is an important measure for environmental management. Untreated domestic and industrial wastewater discharged directly not only harms the natural environment but also damages the surrounding ecosystem and endangers the survival of surrounding organisms. A search revealed CN210905160U, which discloses a wastewater filtration device for environmental treatment. This device includes a vertically arranged support cylinder with an inclined arc-shaped guide plate at its upper end and a spherical guide plate at its lower end. Several support columns are evenly spaced downwards along the edges of the spherical guide plate. A collection cylinder is located at the lower center of the spherical guide plate, with a drain pipe extending to the right. The wastewater is filtered through multiple sets of staggered filtration and guide structures, ensuring comprehensive and thorough filtration. Filtered impurities can be graded and recycled for further refined processing. The tilt angle of the guide plate can be adjusted by swinging the rotating shaft, adapting to wastewater treatment operations with different flow characteristics. This results in high-quality, effective, and targeted wastewater treatment.

[0003] However, in practical applications, contaminants are easily left on the arc-shaped guide plate, and the existing devices do not have a corresponding decontamination mechanism. This leads to excessive accumulation of contaminants, which can easily clog the arc-shaped guide plate and affect the filtration and treatment of wastewater. Therefore, improvements are needed.

[0012] Beneficial effects

[0013] This utility model provides a wastewater filtration device for environmental remediation, which has the following beneficial effects:

[0014] 1. This wastewater filtration device for environmental treatment is equipped with three sets of filtration mechanisms and an angle adjustment mechanism. The angle adjustment mechanism can drive the filtration mechanism to rotate, thereby facilitating the entry of pollutants on the surface of the filter screen into the unsafe tank through the inlet. The rotation of the drive rod can drive the spiral auger blades to rotate, thereby facilitating the discharge of pollutants from the unsafe tank. This effectively avoids the situation where pollutants clog the unsafe tank and affect the pollution filtration treatment.

[0015] 2. This wastewater filtration device for environmental treatment, through the setting of an adjustment mechanism, uses a telescopic push rod for extension and retraction, which can drive the horizontal connecting plate to move up and down. The up and down movement of the horizontal connecting plate can drive the two racks to move up and down, and with the help of the vertical limiting groove plate to limit the racks, the racks and the convex teeth can be meshed to achieve the reciprocating rotation of the incomplete tank, thereby driving the filter screen to rotate up and down. This not only makes it easier for pollutants on the surface of the filter screen to enter the unsafe tank from the sewage inlet, but also the vibration generated by the reciprocating motion can effectively prevent the filter screen from clogging and reduce the equipment failure rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a sewage filtration device for environmental treatment, including a treatment box 1, a collection hopper 2 at the top of the treatment box 1, a grid 3 at the bottom of the collection hopper 2, at least three sets of filtration mechanisms 4 arranged alternately from top to bottom inside the treatment box 1, and all filtration mechanisms 4 are rotatably connected to the treatment box 1. An angle adjustment mechanism 5 for controlling the rotation angle of the filtration mechanisms 4 is provided on the front of the treatment box 1, and support legs 6 are fixedly welded to the four corners of the lower surface of the treatment box 1. The bottom of the treatment box 1 is funnel-shaped and fixedly connected to a drain pipe 7. The filtration mechanism 4 includes an incomplete barrel 8, a filter screen 9, a limiting plate 10, an intercepting baffle 11, a drive rod 12, and spiral auger blades 13. An inlet 14 is opened on the surface of the incomplete barrel 8, and the incomplete barrel 8 is rotatably connected to the treatment box 1. On the filter box 1, the filter screen 9 is fixedly connected to one side of the inlet 14 of the incomplete tank 8, the intercepting baffle 11 is fixedly connected to the other side of the inlet 14 of the incomplete tank 8, the limiting plate 10 is fixedly connected to the upper surface edge of the filter screen 9, the drive rod 12 is rotatably connected to the inner wall of the incomplete tank 8, and the spiral auger blades 13 are fixedly connected to the outer surface of the drive rod 12. By setting three sets of filtration mechanisms 4 and the angle adjustment mechanism 5, the angle adjustment mechanism 5 can drive the filtration mechanism 4 to rotate, so that the pollutants on the surface of the filter screen 9 can enter the incomplete tank from the inlet 14. The rotation of the drive rod 12 can drive the spiral auger blades 13 to rotate, so that the pollutants in the incomplete tank 8 can be discharged, thereby effectively avoiding the situation where pollutants clog the incomplete tank 8 and affect the pollution filtration treatment.

[0023] The filter screens 9 of the three-group filtration mechanism 4 have gradually decreasing pore sizes from top to bottom, which enables graded filtration.

[0024] A servo motor 15 is fixedly connected to the rear surface of the incomplete barrel 8, and the output end of the servo motor 15 is connected to the drive rod 12 for transmission. By setting the servo motor 15, the servo motor 15 can drive the drive rod 12 to rotate, thereby driving the spiral auger blades 13 to rotate.

[0025] The angle adjustment mechanism 5 includes two vertical limiting slot plates 16, two racks 17, a horizontal connecting plate 18, and a telescopic push rod 19. The two vertical limiting slot plates 16 are fixedly connected to the front sides of the processing box 1, and the two racks 17 are slidably connected to the inner walls of the two vertical limiting slot plates 16. The horizontal connecting plate 18 is fixedly connected to the upper ends of the two racks 17. The telescopic push rod 19 is fixedly connected to the center of the front of the processing box 1, and the movable end of the telescopic push rod 19 is fixedly connected to the lower surface of the horizontal connecting plate 18. The outer surfaces of the multiple incomplete barrels 8 are provided with protruding teeth 20 that mesh with the racks 17. The adjustment mechanism uses the telescopic push rod 19 to extend and retract, which can drive the horizontal connecting plate 18 to move up and down. The horizontal connecting plate 18 can drive the two racks 17 to move up and down. The racks 17 are limited by the vertical limiting groove plate 16. The meshing transmission between the racks 17 and the convex teeth 20 can realize the reciprocating rotation of the incomplete barrel 8, which can drive the filter screen plate 9 to rotate up and down. This not only makes it easier for pollutants on the surface of the filter screen plate 9 to enter the unsafe barrel from the sewage inlet 14, but also the vibration generated by the reciprocating motion can effectively prevent the filter screen plate 9 from clogging and reduce the equipment failure rate.

[0026] A limiting baffle 21 is fixedly connected to the front of the processing box 1. By setting the limiting baffle 21, the transverse connecting plate 18 can be limited, thereby controlling the rotation angle of the filter screen plate 9 so that it can reciprocate within a certain angle range.

[0027] A solenoid valve 22 is installed on the drain pipe 7. By installing the solenoid valve 22, it is easy to control the opening and closing of the drain pipe.

[0028] The front of the treatment box 1 is equipped with a waste collection bin 23, which is set at an angle. By setting up the waste collection bin 23, pollutants discharged from multiple incomplete bins 8 can be collected in a unified manner, thereby effectively preventing pollutants from falling to the ground. A conveyor belt can be installed at the bottom of the waste collection bin 23 to facilitate the transportation of waste to a designated location for treatment.

[0029] Working principle: When this wastewater filtration device for environmental treatment is in use, the pollutants to be filtered are first injected into the collection hopper 2. The fence 3 can first intercept larger garbage and debris. Then the wastewater will pass through three filtration mechanisms 4 in sequence. The limiting plate 10 can effectively prevent the wastewater from flowing out of the filter screen 9. The filter screen 9 can filter the wastewater. The adjustment mechanism can drive the limiting plate 10 to rotate back and forth, so that the pollutants on the surface of the filter screen 9 can be discharged from the inlet 14 into the unsafe bin. The intercepting baffle 11 can effectively prevent the pollutants from crossing the inlet 14. The servo motor 15 drives the drive rod 12 to rotate, which can make the spiral auger blades 13 rotate, so that the pollutants entering the unsafe bin 8 can be discharged into the garbage collection tank. After the solenoid valve 22 is opened, the wastewater that has been filtered three times can be discharged from the drain pipe 7.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
