[0037] Embodiment 2

[0038] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 7 For a wastewater treatment device, the clamping mechanism includes a movable plate 26, a first clamping plate 27, a second clamping plate 28, a lifting handle 29 and a spring 30. The movable plate 26 is fixed at the top of the filter plate 5. The movable plate 26 is slidably connected to the filter tank 3. First clamping plates 27 are fixed on both sides of the movable plate 26. The first clamping plates 27 are slidably connected to the filter tank 3.

A spring 30 is sleeved on the outer side of the lifting handle 29. The spring 30 is located on one side of the second clamping plate 28 and inside the filter tank 3.

[0039] The clamping mechanism allows the filter plate 5 to be quickly and easily installed on the sewage treatment device without complex fixing steps or tools, improving the installation efficiency. When it is necessary to clean or replace the filter mesh, it can be easily disassembled from the device through the clamping mechanism, avoiding the cumbersome and inconvenient problems that may be brought by the traditional fixing method.

[0040] A sewage discharge valve 31 is provided at the bottom end of one side of the treatment tank 2. Through the design of the sewage discharge valve 31, it is beneficial to discharge the sediment inside the treatment tank 2. A second discharge port 32 is provided at the bottom end of the outer side of the adsorption tank 9. The second discharge port 32 is used for discharging the treated sewage.

[0041] A control panel 33 is provided at the top end of the treatment tank 2 close to the discharge bin 21. The control panel 33 is electrically connected to the filter tank 3, the aeration blower 6, the second water pump 8, the first rotating motor 10, the second rotating motor 13 and the third rotating motor 23. Through the setting of the control panel 33, the operator is allowed to control multiple motors and water pumps on a centralized interface, avoiding the chaos and inefficiency that may be brought by decentralized operation.

[0042] The usage process of a wastewater treatment device provided by the utility model is as follows: When it is necessary to treat petroleum wastewater, the first water pump 4 is started by controlling through the control panel 33. The first water pump 4 sucks the wastewater into the inside of the filter box 3, filters it through the filter plate 5, and then enters the inside of the treatment box 2. The aeration fan 6 is driven to rotate through the control panel 33, and external air is introduced into the wastewater through the aeration pipe 7 to perform aeration treatment on the wastewater, accelerating the precipitation of the wastewater. After precipitation for a period of time, the second water pump 8 can be started through the control panel 33. The precipitated wastewater is introduced into the adsorption box 9 through the second water pump 8. The first rotating motor 10 is started through the control panel 33. The output end of the first rotating motor 10 drives the first rotating rod 11 to rotate, thereby driving the adsorption plate 12 fixedly connected to the first rotating rod 11 to rotate. The adsorption plate 12 adsorbs the suspended substances in the wastewater. The treated wastewater is discharged from the second discharge port 32;

[0043] When the device has been used for a long time, due to suspended substances, oils, solid impurities, and colloid substances contained in the wastewater, they will gradually accumulate in front of the filter plate 5, affecting the filtering effect of the filter plate 5. At this time, the treatment of the wastewater is stopped. The third rotating motor 23 is started by controlling through the control panel 33. The output end of the third rotating motor 23 drives the rotating gear 24 to rotate. Since the rotating gear 24 is meshed and connected with the moving rack 25, the rotation of the rotating gear 24 drives the moving rack 25 to move, so that the movable plate 26 fixed to the moving rack 25 slides inside the discharge bin 21. Then the second rotating motor 13 is started through the control panel 33. The output end of the second rotating motor 13 drives the second rotating rod 14 to rotate, so that the first bevel gear 16 fixedly connected to the second rotating rod 14 rotates accordingly. Since the first bevel gear 16 is meshed and connected with the second bevel gear 17, the rotation of the first bevel gear 16 drives the second bevel gear 17 to rotate, so that the third rotating rod 18 fixedly connected to the second bevel gear 17 rotates accordingly. Since the third rotating rod 18 is fixedly connected with the scraper 19, the rotation of the third rotating rod 18 drives the scraper 19 to rotate. The cleaning brush 20 fixed to the scraper 19 can further clean the surface of the filter plate 5, thereby extending the service life of the filter plate 5. The rotation of the scraper 19 drives the accumulation in front of the filter plate 5 to move, and the accumulation enters the inside of the discharge bin 21 and is discharged from the device through the first discharge port 22;

[0044] The accumulation of the accumulation in front of the filter plate 5 will increase the resistance of filtration, resulting in a slowdown in the speed of water flow through the filter plate 5 and even blocking the filter plate 5; Through the design of the discharge mechanism, the accumulation can be discharged in time to keep the filter plate 5 unobstructed, reduce the water flow resistance, and thus improve the filtration efficiency;

[0045] When it is necessary to further clean the filter holes of the filter plate 5, pull the lifting handle 29 to one side. Since the lifting handle 29 is fixedly connected to the second clamping plate 28, the movement of the lifting handle 29 drives the second clamping plate 28 to move, so that the spring 30 sleeved on the lifting handle 29 is compressed by the second clamping plate 28. At this time, the second clamping plate 28 is no longer clamped with the first clamping plate 27, so that the movable plate 26 fixed to the first clamping plate 27 can slide out from the inside of the filter box 3, and the filter plate 5 fixed to the movable plate 26 also moves accordingly, so that the filter holes of the filter plate 5 can be cleaned;

[0046] The clamping mechanism allows the filter plate 5 to be quickly and easily installed on the sewage treatment device without complex fixing steps or tools, improving the installation efficiency; when it is necessary to clean or replace the filter screen, it can be easily disassembled from the device through the clamping mechanism, avoiding the cumbersome and inconvenience that may be brought by the traditional fixing method.

Obviously, many modifications and changes can be made according to the content of this specification.
