Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a purification treatment device for treating river water pollution. Background Technology

[0002] Water pollution control technology is a system of techniques that remove pollutants from water and improve water quality through physical, chemical, and biological methods. Purifying rivers is essential for protecting water resources, maintaining aquatic ecological balance, ensuring human water safety, and preserving the ecological functions of rivers.

[0003] Under current conditions, a common method for treating river water pollution is a purification and cleaning device, as disclosed in CN211813792U, which includes a purification shell with a transparent plate on its front surface. A lead screw drives a cleaning brush on the cleaning plate to move up and down across the surface of a filter screen, continuously cleaning it. However, this device only filters through a filter screen, activated carbon mesh, lime mesh, and gauze, and cannot specifically intercept and separate large-volume debris from the wastewater. This large debris accelerates filter screen clogging and damages subsequent filtration components, leading to decreased filtration efficiency. Replacing or repairing components such as the filter screen and activated carbon mesh requires disassembling multiple connecting structures, making the operation cumbersome and time-consuming. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where incomplete filtration of sewage leads to the inability of the filter screen to function properly, and to propose a purification treatment device for treating river water pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A purification and treatment device for treating river water pollution includes a main body connected to a sewage pipe, an inlet connected to the sewage pipe on the main body, an outlet for discharging water into the river, an interceptor frame one for intercepting garbage in the sewage fixedly installed inside the main body, a collection tank for collecting sewage and garbage on the main body, and an interceptor frame two for filtering water from the garbage fixedly installed inside the collection tank, and a guide hole for guiding the filtered water flow inside the main body. The main body has a filter channel that is connected to the guide hole and the water outlet, and the filter channel is equipped with a purification structure for purifying sewage.

[0006] Preferably, the main body has a discharge port that communicates with the collection tank, and the main body is provided with a sealing door for sealing the discharge port.

[0007] Preferably, the purification structure includes a wedge-shaped mesh filter plate fixedly installed inside the main body for filtering large particulate impurities in the wastewater, a receiving tank for collecting large particulate impurities is provided inside the main body, and a filter for further filtering the wastewater is provided on the main body by means of clamps.

[0008] Preferably, the wedge-shaped mesh filter plate has an L-shaped structure, and the filter is composed of a woven mesh filter plate, a composite non-woven fabric filter plate, and a meltblown fabric filter plate.

[0009] Preferably, the clamp component includes a fixing frame that is fixedly installed on the filter and symmetrically arranged, the clamp frame is slidably sleeved on the main body, and a limiting block for limiting the fixing frame is fixedly installed on the clamp frame; The main body is fitted with two symmetrically arranged movable blocks, and springs are welded between the movable blocks and the main body. A connecting block extending out of the main body and integrally connected with the clamp frame is fixedly installed on the movable block.

[0010] Preferably, the clamp frame is a U-shaped structure with openings at both ends, and the main body is threaded with fixing bolts for fixing the clamp frame.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses two interceptor frames to filter larger debris in sewage and collect it into a collection tank. A wedge-shaped mesh filter plate filters larger impurity particles in sewage and collects them into a receiving tank, ensuring the smooth progress of subsequent filtration. A woven mesh filter plate filters fine impurities, a composite non-woven fabric filter plate intercepts colloids and suspended organic matter, and a meltblown fabric filter plate further intercepts residual fine impurities. This achieves multi-stage filtration of sewage from coarse to fine, efficiently removing various pollutants and ensuring that the water quality meets standards.

[0012] 2. This utility model enables quick filter replacement through clamp components. When the filter needs to be replaced periodically, the fixing bolt is loosened, and the clamp frame is pulled downward. The clamp frame drives the connecting block and the moving block to apply pressure to the spring, and the limit block is disconnected from the fixing frame, which facilitates the maintenance or replacement of the filter by the staff and improves the maintenance efficiency of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A purification and treatment device for treating river water pollution includes a main body 1 connected to a sewage pipe, an inlet connected to the sewage pipe on the main body 1, and an outlet for discharging water into the river. An interceptor frame 3 for intercepting garbage in sewage is fixedly installed inside the main body 1. The interceptor frame 3 is made of stainless steel, which effectively intercepts large garbage in sewage. Stainless steel has good corrosion resistance, adapts to the complex environment of sewage, and extends service life.

[0017] The main body 1 is provided with a collection tank 2 for collecting sewage and garbage, and an interceptor frame 2 4 for filtering water in the garbage is fixedly installed in the collection tank 2. The mesh size of the interceptor frame 2 4 is smaller than that of the interceptor frame 3. When receiving the garbage falling from the interceptor frame 3, the water carried in the garbage is filtered out, so that the garbage is initially dehydrated, reducing the difficulty and weight of subsequent garbage treatment. The main body 1 is provided with a guide hole 5 for guiding the filtered water flow.

[0018] The main body 1 has a filter channel 6 that is connected to the guide hole 5 and the water outlet. The filter channel 6 is equipped with a purification structure for purifying sewage. In the purification structure, the wedge mesh filter plate 8 filters large particulate impurities in the sewage and causes them to fall into the receiving tank 7. The woven mesh filter plate, composite non-woven fabric filter plate, and meltblown fabric filter plate of the filter 9 filter fine impurities, intercept colloidal and suspended organic matter, and further intercept residual fine impurities in sequence, so as to achieve the purification of sewage from coarse to fine and ensure that the water quality meets the discharge standards.

[0019] The main body 1 has a discharge port that is connected to the collection tank 2. The main body 1 is equipped with a sealing door for sealing the discharge port. The sealing door is connected to the main body 1 by a hinge. The sealing door is fitted with a sealing strip to improve the sealing performance. After cleaning, the sealing door is closed to ensure the airtightness of the inside of the main body 1 and prevent sewage from leaking from the discharge port.

[0020] The purification structure includes a wedge-shaped mesh filter plate 8 fixedly installed in the main body 1 for filtering large particulate impurities in sewage. The wedge-shaped mesh filter plate 8 is welded from high-strength wedge wires. The special structure of its wedge wires gives it good backwashing performance, reduces the adhesion of impurities on the filter plate surface, and extends the cleaning cycle. The main body 1 is provided with a receiving tank 7 for collecting large particulate impurities.

[0021] The main body 1 is equipped with a filter 9 for further filtration of sewage via a clamp. The fixing frame 10 in the clamp is connected to the filter 9. The clamp frame 11 limits the fixing frame 10 by the limiting block 12. The moving block 13, spring 14, and connecting block 15 cooperate to make the clamp frame 11 stably fix the filter 9. The fixing bolt strengthens the fixation, and the installation and replacement of the filter 9 can be completed quickly, which helps to improve the equipment maintenance efficiency.

[0022] The wedge-shaped filter plate 8 has an L-shaped structure. The filter 9 consists of a woven mesh filter plate, a composite non-woven fabric filter plate, and a meltblown fabric filter plate. The woven mesh filter plate is made of nylon material, which effectively filters fine impurities in sewage. The composite non-woven fabric filter plate is made of a variety of fibers and has good adsorption and interception performance, effectively intercepting colloids and suspended organic matter in sewage. The meltblown fabric filter plate is made of polypropylene material, which has fine fiber diameter and high porosity, further intercepting residual tiny particles and some microorganisms in sewage, ensuring that sewage purification meets discharge standards.

[0023] The clamping component includes a fixing frame 10 that is fixedly installed on the filter 9 and symmetrically arranged. The fixing frame 10 has an L-shaped structure. The main body 1 has a limiting groove corresponding to the fixing frame 10. The clamping frame 11 is slidably sleeved on the main body 1, and a limiting block 12 for limiting the fixing frame 10 is fixedly installed on the clamping frame 11. The fixing frame 10 has a limiting hole corresponding to the limiting block 12.

[0024] Two symmetrically arranged movable blocks 13 are slidably sleeved inside the main body 1, and a spring 14 is welded between the movable blocks 13 and the main body 1. When the spring 14 is in its natural state, it pushes the movable blocks 13 by elastic force, so that the limiting block 12 on the clamp frame 11 is tightly fitted with the fixing frame 10, thereby fixing the filter 9.

[0025] A connecting block 15 extending out of the main body 1 and integrally connected with the clamp frame 11 is fixedly installed on the moving block 13. A limiting hole is provided on the main body 1 to restrict the connecting block 15 and prevent the clamp frame 11 from shifting during movement.

[0026] The clamp bracket 11 is a U-shaped structure with openings at both ends. The main body 1 is threaded with a fixing bolt for fixing the clamp bracket 11. The main body 1 has a threaded hole that matches the fixing bolt. One end of the fixing bolt passes through the clamp bracket 11 and matches the threaded hole on the main body 1. By tightening the fixing bolt, the position of the clamp bracket 11 can be further fixed to prevent it from shifting due to vibration or other factors during equipment operation, thus ensuring the clamp's fixing effect on the filter 9.

[0027] The functional principle of this utility model can be explained through the following operation methods: Wastewater enters the main body 1 through the inlet and first passes through the first interceptor 3. The first interceptor 3 intercepts the larger garbage in the wastewater. The intercepted garbage falls into the collection tank 2. The second interceptor 4 in the collection tank 2 filters the water contained in the garbage. The filtered water flows into the filtration channel 6 through the guide hole 5, and first passes through the wedge-shaped mesh filter plate 8. The wedge-shaped mesh filter plate 8 filters out larger particles of impurities in the wastewater, and the filtered large particles of impurities fall into the receiving tank 7. After being filtered by the wedge mesh filter plate 8, the sewage continues to flow and enters the filter 9. The woven mesh filter plate in the filter 9 filters out the fine impurities in the sewage, the composite non-woven fabric filter plate intercepts the colloids and suspended organic matter in the sewage, and the meltblown fabric filter plate further intercepts the remaining fine impurities in the sewage. After being purified by the multi-stage filtration of the filter 9, the sewage is discharged into the river through the outlet.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
