Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to a water-blocking wall structure in front of a membrane bar screen. Background Technology

[0002] The water-blocking wall in front of the membrane bar screen is a key auxiliary structure to ensure the efficient operation of the bar screen. Its core design revolves around water flow control and debris pretreatment. By constructing a wall structure with a specific height and angle, the water flow speed in front of the screen can be slowed down, and debris accumulation or uneven stress on the screen caused by water flow impact can be avoided. At the same time, it guides suspended and floating debris in the sewage to be evenly distributed on the working surface of the screen, creating stable working conditions for subsequent screen interception and separation operations. Existing water-blocking walls mostly adopt an integrated fixed structure, which makes the disassembly and assembly process cumbersome and laborious. It is difficult to inspect and replace the internal components or damaged parts of the wall separately, which greatly increases the difficulty and cost of maintenance. At the same time, it limits its compatibility with different specifications of bar screens, which is not conducive to the later upgrade and modification of the equipment. Therefore, we propose a water-blocking wall structure in front of the membrane bar screen. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a water-blocking wall structure in front of the membrane grid machine. By adopting a snap-fit ​​connection structure, the support component and the filter component can be independently separated, which significantly improves the convenience of equipment installation and disassembly.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The water-blocking wall structure in front of the membrane bar screen includes a support mechanism, a filter mechanism is installed on the inner side of the support mechanism, and a fixing mechanism is installed on the upper end of the support mechanism. The fixing mechanism includes a fixing plate with a handle at the upper center and connecting blocks at the lower ends of the left and right sides. Extending arms are provided at the lower ends of the left and right sides of the fixing plate, and buckles are provided at the lower center of the extending arms. By setting buckles and connecting blocks to form a snap-fit ​​connection structure, the support component and the filter component can be independently separated, which significantly improves the convenience of equipment installation and disassembly, and facilitates the individual maintenance and cleaning of each component, effectively reducing operation and maintenance costs.

[0005] Furthermore, the filtration mechanism includes a support plate, with locking blocks on the left and right sides of the outer end of the support plate, a filter screen installed in the middle of the inner end of the support plate, and limiting blocks on the left and right sides of the front end of the support plate. By setting locking blocks on the left and right sides of the outer end of the support plate, quick locking and positioning with the support component can be achieved. The filter screen installed in the middle of the outer end ensures the core filtration requirements, and the limiting blocks on the left and right sides of the front end can enhance the structural stability after installation and prevent displacement during operation. The overall structure not only realizes detachable connection between components, but also improves assembly accuracy and operational reliability through multi-part positioning. At the same time, it is easy to disassemble the filter screen and support plate separately for maintenance and cleaning, reducing maintenance difficulty and cost.

[0006] Furthermore, the support mechanism includes a support frame, with a slot in the middle of the inner side of the support frame, a connecting slot at the upper end of the support frame, and a crossbar installed on the inner front end of the support frame. By setting the crossbar, the water flow in front of the screen and the suspended and floating debris in it can be effectively buffered, which can reduce the impact force of the water flow to avoid excessive stress on core components such as the filter screen. At the same time, it can help disperse the distribution of water flow and debris, ensure the stability of the filtration and interception operation, and extend the service life of the equipment.

[0007] Furthermore, the support plate is located inside the support frame and behind the crossbar. By setting the support plate inside the support frame and behind the crossbar, the support frame can provide stable installation support for the support plate, and the buffering effect of the front crossbar can reduce the direct impact and wear of water flow and debris on the support plate and the filter screen on it. At the same time, it ensures the rationality of the filtration path, improves the filtration interception efficiency, and does not affect the independent disassembly and maintenance of each component.

[0008] Furthermore, the fixing plate is located at the upper middle part of the support frame.

[0009] Furthermore, the card block is installed at the inner end of the card slot.

[0010] Furthermore, the buckle is connected to the connecting groove, and the buckle is adapted to the connecting groove.

[0011] Furthermore, the connecting block is a rectangular block structure, and the connecting block is engaged with the inner sidewall of the support frame.

[0012] In summary, this utility model has the following beneficial effects: 1. By setting up buckles and connecting blocks to achieve a snap-fit ​​connection structure, the support component and filter component can be independently separated, which significantly improves the convenience of equipment installation and disassembly. At the same time, it facilitates the individual maintenance and cleaning of each component, effectively reducing operation and maintenance costs. By setting the buckles on the left and right sides of the outer end of the support plate, it can achieve quick snap-fit ​​positioning with the support component. The filter screen installed in the middle of its outer end ensures the core filtration needs. The limiting blocks on the left and right sides of the front end can enhance the structural stability after installation and prevent displacement during operation. The overall structure not only realizes the detachable connection between components, but also improves the assembly accuracy and operational reliability through multi-part positioning. At the same time, it is easy to disassemble the filter screen and support plate separately for maintenance and cleaning, reducing the difficulty and cost of operation and maintenance. 2. By setting up crossbars, the water flow in front of the screen and the suspended and floating debris in it can be effectively buffered, which can reduce the impact of the water flow to avoid excessive stress on the core components such as the filter screen. At the same time, it can help disperse the distribution of water flow and debris, ensure the stability of the filtration and interception operation, and extend the service life of the equipment. By setting the support plate inside the support frame and behind the crossbar, the support frame can provide a stable installation support for the support plate, and the buffering effect of the front crossbar can reduce the direct impact and wear of water flow and debris on the support plate and the filter screen on it. At the same time, it can ensure the rationality of the filtration path, improve the filtration and interception efficiency, and not affect the independent disassembly and maintenance of each component.

Extension arms 304 are provided at the lower ends of the left and right sides of the fixing plate 301. A buckle 305 is provided at the lower center of the extension arm 304. The fixing plate 301 is located at the upper center of the support frame 101. The buckle 305 is connected to the connecting groove 103. The buckle 305 and the connecting groove 103 are adapted to each other. The connecting block 303 is a rectangular block structure. The connecting block 303 is engaged with the inner side wall of the support frame 101. By setting the buckle 305 and the connecting block 303 through the snap-fit ​​connection structure, the support component and the filter component can be independently separated, which significantly improves the convenience of equipment installation and disassembly. At the same time, it facilitates the individual maintenance and cleaning of each component and effectively reduces the operation and maintenance cost.

[0018] Reference Figure 1-5 As shown, the filter mechanism 2 includes a support plate 201. Locking blocks 202 are provided on the left and right sides of the outer end of the support plate 201. A filter screen 203 is installed in the middle of the inner end of the support plate 201. Limiting blocks 204 are provided on the left and right sides of the front end of the support plate 201. The locking blocks 202 are correspondingly installed in the inner end of the locking slot 102. By providing locking blocks 202 on the left and right sides of the outer end of the support plate 201, quick locking and positioning with the support components can be achieved. The filter screen 203 installed in the middle of its outer end ensures the core filtration requirements. The limiting blocks 204 on the left and right sides of the front end enhance the structural stability after installation and prevent displacement during operation. The overall structure not only achieves detachable connection between components but also improves assembly accuracy and operational reliability through multi-part positioning. Simultaneously, it facilitates the separate disassembly of the filter screen 203 and the support plate 201 for maintenance and cleaning, reducing maintenance difficulty and cost.

[0019] Reference Figure 1-5As shown, the support mechanism 1 includes a support frame 101. A slot 102 is provided in the middle of the inner side of the support frame 101. A connecting slot 103 is provided at the upper end of the support frame 101. A crossbar 104 is installed on the inner side of the front end of the support frame 101. By setting the crossbar 104, the water flow in front of the screen and the suspended and floating debris in it can be effectively buffered, which can reduce the impact force of the water flow to avoid excessive stress on core components such as the filter screen 203. At the same time, it can help disperse the distribution of water flow and debris, ensure the stability of the filtration and interception operation, and extend the service life of the equipment.

[0020] Reference Figure 2-5 As shown, the support plate 201 is located inside the support frame 101 and behind the crossbar 104. By setting the support plate 201 inside the support frame 101 and behind the crossbar 104, the support frame 101 can provide a stable installation support for the support plate 201. At the same time, the buffering effect of the front crossbar 104 can reduce the direct impact and wear of water flow and debris on the support plate 201 and the filter screen 203 on it. This also ensures the rationality of the filtration path, improves the filtration interception efficiency, and does not affect the independent disassembly and maintenance of each component.

[0021] Specific implementation process: During operation, sewage first flows to the front end of the support frame 101. The crossbar 104 installed on the inner side buffers, slows down, and disperses the water flow and suspended and floating debris in it. Then, it flows through a reasonable filtration path to the filter screen 203 located inside the support frame 101 and behind the crossbar 104. The filter screen 203 in the middle of the inner end of the support plate 201 achieves core filtration and interception. During this process, the locking blocks 202 on the left and right sides of the outer end of the support plate 201 engage with the locking grooves 102 of the support frame 101. The limiting blocks 204 on the left and right sides of the front end ensure structural stability. The connecting blocks 303 at the lower ends of the left and right sides of the fixing plate 301 are snapped into the inner side wall of the support frame 101, and the buckles 305 of the lower extension arm 304 are matched with the connecting grooves 103 at the upper end of the support frame 101, further reinforcing the overall structure. During operation and maintenance, the components connected by snap-fit ​​can be disassembled to maintain and clean the support plate 201, filter screen 203 and other components separately, taking into account both filtration and interception efficiency and ease of disassembly and maintenance.
