Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device. Background Technology

[0002] Wastewater refers to water that has lost its original function. Wastewater is caused by the introduction of new substances into the water or by changes in external conditions, which cause the water to deteriorate and no longer maintain its original function. Wastewater mainly includes domestic sewage, industrial wastewater, and initial rainwater. The main pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants, which is why wastewater treatment equipment is used.

[0003] According to utility model patent CN221191696U, a wastewater treatment device includes a tank body containing a solid-liquid separation cylinder. A rotating shaft is rotatably connected to the bottom of the inner wall of the tank body. A support plate is located at the top of the rotating shaft, and a cross-shaped connecting block is located at the top of the support plate. A circular connecting seat is located in the middle of the bottom of the solid-liquid separation cylinder. The bottom of the circular connecting seat has a cross-shaped connecting groove for the cross-shaped connecting block to be inserted. An annular fixing block is located on the inner wall of the tank body near the top, and an annular ultraviolet lamp is located at the bottom of the annular fixing block. This wastewater treatment device can indirectly drive the solid-liquid separation cylinder to rotate forward and backward via a servo motor, effectively preventing the solid-liquid separation cylinder from being clogged by filter material. By setting an annular ultraviolet lamp at the bottom of the annular fixing block, the inner wall of the tank body and the outer wall of the solid-liquid separation cylinder can be sterilized, effectively reducing bacterial growth inside the tank body and avoiding any impact on the health of workers.

[0004] Although the above technical solution can achieve solid-liquid separation of sewage, in actual use, the centrifugal force generated when the solid-liquid separation cylinder rotates causes solid waste to stick to its inner wall and cause blockage. In addition, the technical solution cannot treat the sediment in the sewage, and its practical application has certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device that can not only achieve solid-liquid separation and avoid solid waste blockage during wastewater treatment, but also treat sediments in wastewater, thereby improving its applicability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A wastewater treatment device includes a device box with an open top, and partitions that are respectively installed inside the device box and divide it into a sedimentation tank, a sterilization tank, and a water storage tank from back to front. A conveyor is installed at the front end of the sedimentation tank opening at an angle downwards from front to back and extends into the tank. A guide plate is installed at the rear end of the sedimentation tank opening at an angle downwards from back to front and extends above the lowest position of the conveyor. A U-shaped enclosure is provided at the rear of the upper end of the sedimentation tank. Water guide pipes are provided at the rear ends of the inner walls of the sedimentation tank and the sterilization tank. A filter cover is provided at the rear end of the inner wall of the sedimentation tank to cover the corresponding water guide pipes. A drain pipe is provided at the rear end of the outer wall of the water storage tank.

[0008] The sterilization tank and the water storage tank are fitted with a cover that can be opened on one side. A drive motor is installed on one side above the cover. A first pulley is installed on the outer wall of the drive motor's power output shaft. A second pulley is installed on one side of the outer wall of the conveyor. The first pulley and the second pulley are connected by a belt drive. Waterproof sterilization components are fitted on both the front, back, left, and right sides of the inner wall of the sterilization tank and the water storage tank. Air blowing components are installed in the sedimentation tank away from its bottom and at the bottom of the inner wall of the sterilization tank. A water quality analyzer is installed in the water storage tank. An air pump and control panel are installed on the upper part of the cover on the side of the drive motor. The air outlet of the air pump is connected to an air outlet pipe that is connected to all the air blowing components.

[0009] By adopting the above technical solution, when using the device, first install it in a suitable position and fix it, then power on the device, operate the control panel to make the drive motor work, the drive motor will drive the first pulley to rotate, and drive the second pulley and the conveyor to rotate through the belt, then discharge the sewage onto the guide plate, the sewage will fall down onto the conveyor along the guide plate, the solid waste will be transported out by the conveyor, and the sewage will fall directly into the sedimentation tank. As the sewage level increases, the water in the sedimentation tank will flow into the sterilization tank through the water guide pipe for sterilization, and the sterilized water will flow into the storage tank and finally be discharged through the drain pipe.

[0010] When wastewater passes through the sedimentation tank and sterilization tank, the air pump operates and blows air into the wastewater through the air blowing component. The small bubbles generated by the air blowing float upwards, carrying small particles of impurities in the wastewater to the surface. When the wastewater in the sedimentation tank flows into the sterilization tank, the small particles of impurities are blocked by the filter cover, preventing them from entering the sterilization tank. After the water entering the sterilization tank and the storage tank is treated by the sterilization component, the content of microorganisms is reduced, which facilitates subsequent processing.

[0011] A further feature of this invention is that an L-shaped water guide plate is provided at the rear end of the inner wall of the sedimentation tank below the conveyor, and a gap is left between the front end of the outer wall of the water guide plate and the inner wall of the sedimentation tank.

[0012] By adopting the above technical solution, the water can be diverted through the guide plate to avoid water falling directly into the sedimentation tank and causing turbulence in the sedimentation tank, thus affecting the sedimentation effect of sewage.

[0013] A further feature of this invention is that the sterilization component includes a fixed frame with openings at both the front and rear ends, a plurality of photocatalyst plates evenly distributed on the inner wall of the fixed frame and communicating with it, and a plurality of ultraviolet lamps respectively disposed between two adjacent photocatalyst plates.

[0014] By adopting the above technical solutions, wastewater can be sterilized to a certain extent, reducing the content of microorganisms in the water.

[0015] A further feature of this invention is that the air blowing assembly includes a rectangular air supply pipe, several connecting pipes evenly distributed on the left and right sides of the inner wall of the air supply pipe and connected to them, and several one-way valves installed at the bottom of the connecting pipes and connected to them.

[0016] A further feature of this invention is that the one-way valve corresponding to the air blowing assembly in the sedimentation tank is positioned towards its bottom, and the one-way valve corresponding to the air blowing assembly in the sterilization tank is positioned towards its top.

[0017] A further feature of this invention is that a sludge removal port is provided at the lower front end of the outer wall of the sedimentation tank, and a sludge discharge component communicating with the sludge removal port is provided at the front end of the outer wall of the sedimentation tank. Sliding grooves are provided on both the left and right sides of the inner wall of the sedimentation tank and the sludge discharge component. A sludge removal plate arranged along its length is slidably connected to the two sliding grooves. Pull ropes extending to the opening end of the sludge discharge component are provided on both the left and right sides of the front end of the sludge removal plate.

[0018] By adopting the above technical solution, it is easier for staff to clean the sediment in the sedimentation tank after a period of use.

[0019] A further feature of this invention is that the sludge removal assembly includes a sludge removal pipe with openings at both the front and rear ends, a fixing groove formed at the upper front end of the outer wall of the sludge removal pipe and pointing downwards, and a baffle that slides along the height direction of the fixing groove and is sealed to it.

[0020] In summary, this utility model has the following beneficial effects:

[0021] Firstly, this utility model can not only achieve solid-liquid separation and avoid solid waste blockage when treating sewage, but also treat the sediment in sewage, thus improving its applicability.

[0022] Secondly, the water guide plate of this utility model can prevent water from falling directly into the sedimentation tank and causing the water in the sedimentation tank to vibrate, thereby affecting the sedimentation effect of sewage.

[0023] Thirdly, the air pump of this utility model can not only increase the oxygen content of sewage during sewage treatment, preventing the water from becoming oxygen-deficient and smelly, but also bring tiny impurities in the sewage to the surface through the generated bubbles, facilitating subsequent processing of the water.

A sliding groove 4 is provided on the left and right sides of the inner wall of the sedimentation tank 12 and the sludge discharge pipe 32. A sludge removal plate 41, which is set along the length direction of the two sliding grooves 4, is slidably connected to them. On both the left and right sides of the front end of the sludge removal plate 41, there is a pull rope 42 that extends to the opening end of the sludge discharge component 31. In the initial state, the sludge removal plate 41 is located at the rear end of the inner wall of the sedimentation tank 12. A U-shaped enclosure 22 is set behind the upper end of the sedimentation tank 12. A water guide pipe 23 is set at the rear end of the inner wall of the sedimentation tank 12 and the sterilization tank 13. The lower end of each water guide pipe 23 is close to the bottom of the device box 1. A filter cover 25 is set at the rear end of the inner wall of the sedimentation tank 12 to cover the corresponding water guide pipe 23. A drain pipe 24 is set at the rear end of the outer wall of the water storage tank 14.

[0036] The sterilization tank 13 and the water storage tank 14 are fitted with a cover plate 15 that can be opened on one side. A drive motor 5 is installed on one side above the cover plate 15. A first pulley 51 is installed on the outer wall of the power output shaft of the drive motor 5. A second pulley 52 is installed on one side of the outer wall of the conveyor 2. The first pulley 51 and the second pulley 52 are driven by a belt 53. A waterproof sterilization component 7 is fitted between the front, back and left and right sides of the inner wall of the sterilization tank 13 and the water storage tank 14. The sterilization component 7 includes a fixed frame 71 with openings at both the front and back ends, multiple photocatalyst plates 72 made of titanium dioxide that are evenly distributed on the inner wall of the fixed frame 71 and communicate with it, and several ultraviolet lamps 73 that are respectively set between two adjacent photocatalyst plates 72.

[0037] An air blowing assembly 6 is installed in the sedimentation tank 12 at a position away from its bottom and at the bottom of the inner wall of the sterilization tank 13. The air blowing assembly 6 includes an air supply pipe 61 arranged in a rectangle, several connecting pipes 62 distributed at equal intervals on the left and right sides of the inner wall of the air supply pipe 61 and connected to it, and several one-way valves 63 installed at the bottom of the connecting pipes 62 and connected to them. The one-way valves 63 on the connecting pipes 62 in the sedimentation tank 12 are arranged facing the bottom, and the one-way valves 63 on the connecting pipes 62 in the sterilization tank 13 are arranged facing upwards. A water quality tester 75 is installed in the water storage tank 14. An air pump 64 and a control panel 74 are installed on the upper end of the cover plate 15 on one side of the drive motor 5. The air outlet of the air pump 64 is provided with an air outlet pipe 65 that is connected to each air blowing assembly 6. The drive motor 5, the air pump 64 and the sterilization are all electrically connected to the control panel 74.

[0038] Instructions for use: First, install and secure the device box 1 in a suitable position. Then, power on the device and operate the control panel 74 to activate the drive motor 5 on the cover plate 15. The drive motor 5 will rotate the first pulley 51, which in turn will drive the second pulley 52 and the conveyor 2 via the belt 53. Wastewater will then be discharged onto the guide plate 21. The enclosure 22 prevents wastewater from splashing onto the drive motor 5. The wastewater will fall down the guide plate 21 onto the conveyor 2, while solid waste will be conveyed outwards via the conveyor 2. The wastewater flows down the guide plate 26 into the sedimentation tank 12. When the wastewater flows into the sedimentation tank 12, the guide plate 26 can reduce the impact of the subsequent water on the original water in the sedimentation tank 12, and avoid affecting the sedimentation of impurities in the water. As the height of the wastewater increases, the water in the sedimentation tank 12 will flow into the sterilization tank 13 through the guide pipe 23 for sterilization. When the wastewater flows into the sterilization tank 13 through the guide pipe 23, the filter cover 25 can block the impurities floating on the water surface and prevent them from flowing into the sterilization tank 13.

[0039] After sterilization, the water flows into the storage tank 14 and is finally discharged through the drain pipe 24. When the sewage passes through the sedimentation tank 12 and the sterilization tank 13, the air pump 64 will work. The gas generated by the air pump 64 will enter the air supply pipe 61 and connecting pipe 62 of the air blowing assembly 6 through the air outlet pipe 65, and then blow out from the one-way valve 63 to blow gas into the sewage. The blown gas will generate bubbles in the water and float upward. When the small bubbles generated by the air blown float upward, they can carry small particles of impurities in the sewage to the surface. Since the one-way valve 63 of the air blowing assembly 6 in the sedimentation tank 12 is oriented in the same direction, the settled impurities will not block the one-way valve 63 and will not affect its normal operation.

[0040] After the water entering the sterilization tank 13 and the water storage tank 14 is treated by the sterilization component 7, the content of microorganisms is reduced, which facilitates subsequent processing. When the ultraviolet lamp 73 in the fixed frame 71 is working, its light shines on the photocatalyst plate 72. The catalytic effect of the photocatalyst plate 72, made of titanium dioxide, can sterilize the water. The water quality tester 75 can monitor the water quality in the water storage tank 14 in real time. After a period of use, the sediment in the sedimentation tank 12 can be cleaned. Open the baffle 34 of the sludge removal component and let it slide upward along the fixed groove 33 to discharge the water in the sedimentation tank 12. Then, the staff can pull the sludge removal plate 41 along the slide 4 towards the sludge removal port 3 through the two pull ropes 42 to remove the sludge at the bottom of the inner wall of the sedimentation tank 12 through the sludge discharge pipe 32. Finally, restore it to the initial state and it can be used again.

[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
