Description

Technical Field

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

[0002] Wastewater treatment is the process of treating wastewater generated from domestic, industrial, and agricultural activities using physical, chemical, and biological technologies to remove pollutants and improve water quality. Its core objective is to transform wastewater that does not meet discharge standards into water that can be safely discharged into natural water bodies or reused for irrigation, industrial cooling, and other applications, thus preventing environmental pollution, ecological harm, and human health risks. The treatment process first uses physical processes such as screens and sedimentation tanks to remove impurities such as silt and floating debris; then, a bioreactor allows microorganisms to decompose organic matter; finally, disinfection and filtration reduce pollutant concentrations. It is a crucial link in water resource recycling and is of great significance for protecting the water environment and alleviating water shortages.

[0003] In the bar screen filtration stage of wastewater treatment, the problems caused by sludge are particularly prominent. Due to the complex sources of wastewater, the composition of sludge is highly uncertain. In addition to common sediments, fibers, and plastic fragments, it may also contain lumpy impurities from industrial production residues and entangled materials from domestic waste. These components easily become entangled on the bar screen bars or stuck in the gaps between the bars under the impact of water flow, causing blockage of the bar screen filtration channels. Blockage not only reduces the efficiency of wastewater flow and affects the normal operation of subsequent treatment processes, but also requires frequent shutdowns for maintenance. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a continuous wastewater treatment device with good filtration performance, low clogging resistance, and convenient maintenance in case of clogging.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a continuous wastewater treatment device, comprising:

[0006] The docking box is sealed with an inspection cover on top.

[0007] The processing tube is sealed and fixed on one side of the docking box. A baffle is integrally formed near the docking box end. Several through slots are opened on the baffle. A filter frame is detachably installed inside the processing tube. Several filter plates are detachably installed on the filter frame. The mesh size of the filter plates increases from the end closest to the docking box end.

[0008] The collection box is fixedly installed below the docking box, and a debris removal port is provided on one side of the lower end.

[0009] Furthermore, the upper edge of the inspection cover extends outward and is provided with a retaining rim.

[0010] Furthermore, the baffle is an arc-shaped plate that protrudes from the center toward the docking box side.

[0011] Furthermore, the filter frame is a square frame, and the inner wall of the processing tube is symmetrically provided with guide grooves that match the filter frame. The filter frame is slidably disposed in the guide grooves on both sides. The end of the side wall of the filter frame and the end of the side wall of the processing tube are provided with matching pin holes. The filter frame and the processing tube are fixed together by fixing pins passing through the pin holes.

[0012] Furthermore, the filter frame is fixedly provided with several arc-shaped support strips that match the filter plates at equal intervals, and the edges of the filter plates are snapped into the arc-shaped support strips. The diameter of the filter plates is adapted to the inner diameter of the processing pipe.

[0013] Furthermore, a sealing cover is provided inside the impurity removal port.

[0014] Compared with existing technologies, this invention has the following advantages: the arc-shaped baffle can block some large impurities, causing them to fall into the collection box and reducing the burden on the filter plates. The filter plates are arranged in ascending order of filter pore size, progressively intercepting impurities from coarse to fine filtration. Furthermore, the diameter of the filter plates is matched to the inner diameter of the treatment pipe, preventing sewage leakage from affecting the filtration effect. The arc-shaped baffle can evenly guide water, allowing impurities to fully contact the filter structure. The ascending filter pore size can intercept impurities of different sizes in stages, preventing rapid clogging of a single filter pore. The inspection cover with buckle is easy to open, and the filter frame can be quickly disassembled for cleaning or replacement of the filter plates via guide grooves and fixing pins. The impurity removal port of the collection box has a sealing cover, making impurity cleaning convenient. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1 Appendix Figure 3A continuous wastewater treatment device includes: a docking box 1, with a maintenance cover 2 sealed on the top. The upper edge of the maintenance cover 2 extends outward with a snap edge, which facilitates the operator to manually pull open the maintenance cover, improving the convenience of maintenance operations and enhancing the sealing effect of the docking box 1.

[0022] Combined with appendix Figure 1 Appendix Figure 3 The treatment pipe 3 is sealed and fixed on one side of the docking box 1. A baffle 4 is integrally formed near the docking box 1. The baffle 4 has several through grooves 5. The baffle 4 is an arc-shaped plate that protrudes from the center towards the docking box 1. It can guide the sewage, reduce the impact of water flow, and make the sewage enter the treatment pipe 3 more evenly through the through grooves 5. It can also effectively block impurities and make them fall smoothly.

[0023] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The treatment pipe 3 is detachably equipped with a filter frame 6, which is a square frame. Symmetrical guide grooves matching the filter frame 6 are provided on the inner wall of the treatment pipe 3. The filter frame 6 is slidably disposed within the guide grooves on both sides. Matching pin holes 10 are provided at the ends of the side walls of the filter frame 6 and the treatment pipe 3. The filter frame 6 and the treatment pipe 3 are fixed together by fixing pins passing through the pin holes 10, ensuring installation stability and facilitating quick disassembly of the filter frame 6 for cleaning or replacement. Several filter plates 7 are detachably mounted on the filter frame 6, with the mesh size of the filter plates 7 increasing from the end closest to the docking box 1. Several arc-shaped support strips 11 matching the filter plates 7 are fixedly mounted on the filter frame 6 at equal intervals. The edges of the filter plates 7 are engaged within the arc-shaped support strips 11, enabling quick assembly and disassembly of the filter plates 7. The diameter of the filter plates 7 is adapted to the inner diameter of the treatment pipe 3, ensuring leak-free wastewater filtration.

[0024] Combined with appendix Figure 1 Appendix Figure 4 The collection box 8 is fixedly installed below the docking box 1, and a cleaning port 9 is provided on one side of its lower end. The cleaning port 9 is equipped with a sealing cover, which can keep the collection box 8 sealed during the collection of impurities to prevent odor from escaping, and at the same time facilitates opening and cleaning of impurities when needed.

[0025] The specific implementation of this utility model is as follows: In use, the docking box 1 is connected to the sewage discharge mechanism on the side away from the treatment pipe 3. Sewage first enters the docking box 1, and the inspection cover 2 on top of the docking box 1 is closed to ensure sealing. When the sewage flows towards the treatment pipe 3, it will first come into contact with the arc-shaped baffle 4 at the end of the treatment pipe 3 near the docking box 1. The baffle 4 guides the sewage and slows down the water flow impact, allowing the sewage to pass evenly through the through groove 5 on it into the treatment pipe 3, while blocking some large impurities, allowing the impurities to fall into the collection box 8 below the docking box 1. The sewage entering the treatment pipe 3 passes through several filter plates 7 on the filter frame 6 in sequence. The filter plates 7 have an increasing mesh size from the end closest to the docking box 1, gradually performing coarse filtration to fine filtration of the sewage, intercepting impurities of different sizes. When cleaning or maintenance is required, the operator can pull the buckle of the inspection cover 2 to open the inspection cover 2, clean the baffle 4, and also pull out the fixing pin in the pin hole 10 on the side wall of the filter frame 6 and the treatment pipe 3, pull out the filter frame 6 along the guide groove on the inner wall of the treatment pipe 3, remove the filter plate 7 on the arc-shaped support strip 11 for cleaning or replacement, and then open the sealing cover of the impurity removal port 9 on the lower side of the collection box 8 to clean the collected impurities. After completing the maintenance, the components can be reassembled and used again.
