Description
Technical Field
[0001] This utility model relates to the technical field of sewage treatment bar screens, and in particular to a sewage treatment bar screen with a self-rinsing function. Background Technology
[0002] In the pretreatment stage of wastewater treatment, bar screens play a crucial role in intercepting solid impurities. However, traditional bar screens have significant limitations. After long-term use, impurities tend to adhere to the inner walls of the drainage holes and gradually accumulate, leading to clogging and slowing down the wastewater flow, which severely affects pretreatment efficiency. Moreover, cleaning requires manual disassembly and cleaning after the machine is shut down, which interrupts the wastewater treatment process, consumes a lot of manpower, and results in high operation and maintenance costs. In addition, traditional equipment is mostly a single-stage filtration structure, which is difficult to intercept fine impurities. These impurities enter subsequent processes with the wastewater, which will increase the load on subsequent treatment units and cannot meet the current wastewater treatment requirements for efficient, continuous, and low-maintenance operation, thus bringing certain adverse effects to the user experience. In order to overcome the shortcomings of existing technologies, we propose a wastewater treatment bar screen with a self-washing function. Utility Model Content

Multiple sets of mounting parts are detachably installed on one side of each chain. A bar screen is fixedly installed on one side of each pair of corresponding mounting parts, and the surface of the bar screen has multiple drainage holes. A filter plate is detachably connected between the two uprights, and one side of the filter plate is fixedly connected to... The system is equipped with multiple fixed plates corresponding to the drain holes. A water pump is detachably connected to the top of one of the support plates. A water pump pipe is detachably connected to one side of the water pump, and a water delivery pipe is detachably connected to the other end of the water pump. A diversion box is detachably connected between the two support plates, and multiple nozzles are detachably connected to the lower end of the diversion box. Each of the two support plates has an insertion slot at one end, and a snap-fit hole is provided on one side of the support plate corresponding to the insertion slot. An insertion block is inserted into the insertion slot, and a spring is detachably connected to the insertion block. The other end of the spring abuts against a limit plate, and a snap-fit block is fixedly connected to one end of the limit plate. A sludge collection box is fixedly connected to one end of each of the two insertion blocks, and a filter screen is detachably connected to the bottom of the sludge collection box. A guide plate is fixedly connected between the two support plates.
[0005] Preferably, the support frame has an L-shaped structure, and the connection between the support frame and the support plate is provided with reinforcing ribs. The servo motor is detachably connected to the support frame by bolts, and the output shaft of the servo motor is connected to the first rotating rod by a coupling.
[0006] Preferably, the grating is made of stainless steel, and the drainage holes on the surface of the grating are rectangular in structure. The multiple drainage holes are arranged at equal intervals on the surface of the grating, and the diameter of the drainage holes is the same.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This wastewater treatment bar screen with self-washing function effectively solves the problems of existing wastewater treatment bar screens, such as decreased filtration efficiency due to impurities clogging the drain holes and the need for frequent manual cleaning, through its self-washing system and dual filtration structure. The diversion box, together with equally spaced nozzles, can evenly distribute the treated water and perform high-pressure washing on the moving bar screen at an acute angle, ensuring that there is no residual blockage in the drain holes. At the same time, after the bar screen performs initial filtration, the filter plate and the corresponding fixed plate form a secondary filtration, further intercepting fine impurities and significantly improving the accuracy of wastewater filtration. This design eliminates the need for shutdown for cleaning, ensuring continuous operation of wastewater treatment, reducing manual maintenance costs, and adapting to the high-efficiency operation requirements of various low-to-medium concentration wastewater treatment scenarios.

The anti-corrosion coating on the inner wall extends its service life, and the nylon filter screen at the bottom can intercept impurities in the flushing wastewater, realizing the separation and recycling of impurities and wastewater, avoiding secondary pollution. The arc-shaped guide plate, together with the side baffles, can accurately guide the flushed impurities and water into the sludge receiving box, preventing splashing and simplifying the impurity cleaning process, improving the convenience of operation and maintenance, and reducing resource waste, which meets the technical requirements of green wastewater treatment.

[0015] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a wastewater treatment bar screen with self-flushing function includes two support plates 1. A mounting bracket 2 is fixedly connected to one side of each support plate 1. One support plate 1 has an L-shaped support frame 3 with reinforcing ribs at the connection point, which is detachably connected to one side. A servo motor 4 is detachably connected to the upper end of the support frame 3 via bolts. The output shaft of the servo motor 4 is detachably connected to a first rotating rod 5 via a coupling. A second rotating rod 6 is rotatably connected between the two support plates 1. Two gears 7 are symmetrically fixed to the outer surfaces of both the first rotating rod 5 and the second rotating rod 6. Each pair of gears... Chains 8 are meshed on both gears 7. Multiple sets of mounting parts 9 can be detachably installed on one side of each chain 8. A stainless steel grating plate 10 is fixedly installed on one side of every two corresponding mounting parts 9. The surface of the grating plate 10 has multiple rectangular drainage holes 11 arranged at equal intervals and with the same hole size. A filter plate 12 is detachably connected between the two supporting plates 1. Multiple fixing plates 13 corresponding to the drainage holes 11 are fixedly connected to one side of the filter plate 12. A water pump 14 is detachably connected to the top of one of the supporting plates 1, and a water pump pipe 1 is detachably connected to one side of the water pump 14. 5. A water supply pipe 16 is detachably connected to the other end. A rectangular hollow diversion box 17 is detachably connected between the two supporting uprights 1. One end of the diversion box 17 is connected to the water supply pipe 16. Multiple nozzles 18 arranged linearly at equal intervals and whose water outlet direction forms an acute angle with the grid plate 10 are detachably connected to the lower end of the diversion box 17. Each of the two supporting uprights 1 has an insertion groove 19 at one end. A snap-fit hole 20 is opened on one side of the supporting upright 1 corresponding to the insertion groove 19. An insertion block 21 is inserted into the insertion groove 19. A spring 22 is detachably connected to the insertion block 21. The other end of the spring 22 abuts against... A limiting plate 23 is connected to one end of the limiting plate 23, and a snap-fit block 24 that can engage with the snap-fit hole 20 is fixedly connected to one end of the two plug-in blocks 21. A sludge collection box 25 with an anti-corrosion coating on its inner wall is fixedly connected to one end of the two plug-in blocks 21. A nylon filter screen 26 with fine mesh is detachably connected to the bottom of the sludge collection box 25 by a snap-fit. An arc-shaped stainless steel plate guide plate 27 is also fixedly connected between the two support uprights 1. The upper edge of the guide plate 27 is flush with the highest point of the grid plate 10, and the lower edge extends into the sludge collection box 25. The two sides of the guide plate 27 are provided with upward-folding baffles with a certain height.
[0016] It should be noted that this utility model is a sewage treatment bar screen with a self-rinsing function. In use, the entire device is first fixedly installed at the designated work position in the sewage treatment system using the mounting bracket 2. The servo motor 4 is then started. The servo motor 4 drives the first rotating rod 5 to rotate via a coupling. The first rotating rod 5 drives the second rotating rod 6 to rotate synchronously through the meshing transmission of the gear 7 and the chain 8. This causes the chain 8 to drive the mounting component 9 and the bar screen 10 to circulate between the supporting uprights 1. When sewage flows through the device, the bar screen 10 initially intercepts and filters solid impurities in the sewage through the drainage holes 11 on its surface. Simultaneously, the filter plate 12, in conjunction with the fixing plate 13, performs secondary filtration of the sewage and provides auxiliary support and stability to the bar screen 10. When the bar screen 10 moves with the chain 8 to a position close to the diversion box 17, the water pump 14 draws treated water through the pumping pipe 15 and transports it to the diversion box 17 via the water delivery pipe 16. The diversion box 17 then evenly distributes the water to various locations. The nozzle 18 applies high pressure to wash away residual impurities adhering to the surface of the grating plate 10 at an acute angle to it, preventing impurities from clogging the drain holes 11. After washing, the impurities and some water fall into the collection box 25 under the guidance of the guide plate 27. The filter screen 26 at the bottom of the collection box 25 filters the water in the box again, while the impurities remain in the collection box 25. When it is necessary to clean the collection box 25, press the locking blocks 24 on both sides of the support plate 1. 24. The compression spring 22 moves the limiting plate 23 into the insertion block 21, causing the locking block 24 to disengage from the locking hole 20. At this time, the insertion block 21 and the sludge collection box 25 can be pulled out from the insertion groove 19. After removing the filter screen 26 by the buckle, the impurities in the box are cleaned. After cleaning, the insertion block 21 is inserted into the insertion groove 19. The spring 22 returns to its original position and pushes the limiting plate 23 and the locking block 24 into the locking hole 20, thus fixing the sludge collection box 25 in place. The device can then continue to be used.
