TECHNICAL FIELD
[0001] The utility model relates to water supply and drainage filtration equipment field especially a kind of anti-clogging filter equipment for municipal water supply and drainage construction. BACKGROUND
[0002] Municipal water supply and drainage refers to the infrastructure network covering water supply, drainage, sewage treatment and other aspects in city, which provides necessary support and guarantee for residents' life and city operation. It includes water supply facilities, sewage treatment equipment and related pipelines and equipment. Water supply system is one of the important components of municipal water supply and drainage system, and its main task is to introduce water resources into city and distribute water to each residential area and unit through pipe network. Water supply system usually includes water source, water intake facility, water plant, reservoir, water pump station and water conveying pipeline. In the process of city water supply, it is necessary to ensure the safety of water quality, the stability of water supply and the reasonable regulation of water supply pressure. Drainage system is another important component of municipal water supply and drainage system, and its main task is to discharge rainfall and domestic wastewater in city and treat them to prevent waterlogging and sewage retention in city. Drainage system generally includes rainwater pipe network and sewage pipe network. Rainwater pipe network is used to collect rainfall in city and discharge water into river, lake or other water collection facilities. Sewage pipe network is used to collect domestic wastewater and industrial wastewater and send them to sewage treatment plant for treatment.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] like Figure 1 - Figure 4 As shown, an anti-clogging filtration device for municipal water supply and drainage construction mainly consists of a support frame 1 and a filter screen 4. The support frame 1 is designed to be installed in the municipal water supply and drainage pipeline and is connected to the filter screen 4 via a rotating component 2 and a rotating bar 3, enabling the filter screen 4 to effectively filter the water flowing in the municipal water supply and drainage pipeline. The filter screen 4 is fixed to the support frame 1 with fixing bolts 5, ensuring the stability and reliability of the device. Furthermore, the filter screen 4, through the cooperation of the rotating component 2 and the rotating bar 3, can achieve flexible angle adjustment to adapt to different filtration needs.
[0029] To further improve filtration efficiency and ease of maintenance, support frames 6 are installed on both sides of the front end of the support frame 1. A limiting tube 7 is installed at the front end of the support frame 6, and a linear actuator 8 is installed at the upper end of the limiting tube 7. A connecting rod 9 is connected to the telescopic end of the linear actuator 8, and a movable rod 10 is installed at the lower end of the connecting rod 9. A roller 11 is located between the two movable rods 10, and multiple cleaning brushes 12 are provided on the side wall of the roller 11. The linear actuator 8 can drive the roller 11 to move up and down. Through the rotational movement of the cleaning brushes 12, the blockages on the filter screen 4 are effectively removed, thereby keeping the filter screen 4 clean and preventing clogging.
[0030] In the structural design of the filter screen 4, the rotating component 2 is divided into two parts: a support and a rotating shaft. The rotating shaft is placed on the support, and the support is fixed to the support frame 1 by welding. The rotating shaft is connected to the rotating strip 3, ensuring a stable connection between the rotating component 2 and the rotating strip 3. Two rotating components 2 are distributed at both ends of the rotating strip 3. One end of the rotating component 2 is connected to the frame of the filter screen 4, while the other end is connected to the support frame 1. The rotating strip 3 includes a large telescopic strip and a small telescopic strip, both of which have square strips. The connection between the large and small telescopic strips is achieved by rotating the shaft. By adjusting the length of the rotating strip 3, the tilt angle of the filter screen 4 can be changed to adapt to different filtration conditions.
[0031] The filter screen 4 has a protruding block at the upper center, and screw holes are opened on the protruding block. These screw holes are aligned with the screw holes on the support frame 1. By inserting fixing bolts 5 into the screw holes on the protruding block, the filter screen 4 can be firmly fixed to the support frame 1, ensuring the stability of the filter screen 4 during use.
[0032] In order to ensure the smooth movement of the movable rod 10, the limiting pipe 7 is welded and fixed on the support frame 6, and the front end of the limiting pipe 7 is provided with a sliding groove, and the movable rod 10 moves up and down along the sliding groove. In order to reduce the friction at the connection between the movable rod 10 and the limiting pipe 7, the connection is designed to be smooth, thereby improving the service life and operating efficiency of the equipment.
[0033] The connecting rod 9 is connected with the telescopic end of the linear actuator 8 through bolts, ensuring the stability of the connection. The connecting rod 9 is fixed with the movable rod 10 through bolts, ensuring the stability and reliability of the movable rod 10. The linear actuator 8 can be a hydraulic cylinder or an electric push rod, which is selected according to actual needs to meet different working conditions.
[0034] The roller 11 is limited on the movable rod 10 through a rotating shaft and a nut, ensuring the stable rotation of the roller 11. The cleaning brushes 12 are annularly distributed on the roller 11, and when the roller 11 rotates, the cleaning brushes 12 can effectively remove the blockage on the filter screen 4, keeping the filter screen 4 clean, thereby ensuring the efficient operation of the filtering equipment.
[0035] The installation process is as follows: install the support frame 1 in the municipal water supply and drainage pipeline, ensure that its position is correct and stable. Connect the rotating part 2 and the rotating strip 3 to the support frame 1, ensure the stability of the connection. Connect the filter screen 4 to the support frame 1 through the rotating part 2 and the rotating strip 3, ensure that the filter screen 4 can be flexibly adjusted in angle. Use the fixing bolts 5 to align and fix the protruding blocks of the filter screen 4 with the screw holes on the support frame 1, ensure the stability of the filter screen 4. Install the support frame 6 on both sides of the front end of the support frame 1, then install the limiting pipe 7 and the linear actuator 8. The connecting rod 9 is connected to the telescopic end of the linear actuator 8 and fixed to the movable rod 10. Ensure that the roller 11 and the cleaning brushes 12 are correctly installed between the movable rod 10. After installation is completed, test the equipment to ensure that all parts move smoothly without abnormal noise or jamming phenomenon.
[0036] The use process is as follows: start the linear actuator 8 to make the roller 11 and the cleaning brushes 12 start to rotate. According to the actual filtering demand, adjust the inclination angle of the filter screen 4 by rotating the rotating strip 3. The flowing water in the municipal water supply and drainage pipeline passes through the support frame 1, and the filter screen 4 filters the flowing water and removes impurities. The cleaning brushes 12 rotate under the drive of the roller 11, removing the blockage on the filter screen 4 and keeping the filter screen 4 clean. Regularly check the running state of the equipment to ensure the filtering efficiency and the stability of the equipment.
[0037] Cleaning anti-blocking process: regularly check the filter screen 4 and the cleaning brush 12, ensure that there is no blockage accumulation. If the filter screen 4 or the cleaning brush 12 is found to have blockage, manually remove the blockage. Start the linear drive 8, make the roller 11 and the cleaning brush 12 rotate, automatically remove the blockage on the filter screen 4. After the cleaning is completed, check whether the filter screen 4 is clean, ensure that there is no residual blockage. Regularly maintain the equipment, including checking the fastening of the fixing bolt 5, ensuring the stability and reliability of the support frame 1 and the filter screen 4.
