Description

Technical Field

[0001] This utility model relates to the field of bar screen technology, and in particular to a bar screen for sewage treatment. Background Technology

[0002] In the process of wastewater treatment, the raw wastewater usually contains a large number of solid impurities, such as branches, paper, and cloth. If these impurities directly enter the subsequent treatment equipment, it will cause equipment blockage, malfunction, and reduced treatment effect.

[0003] The function of a bar screen is to remove large solid particles from raw wastewater through a physical process, thereby protecting the normal operation of subsequent treatment equipment. During bar screen operation, the discharge of solid impurities may be uneven, sometimes too much and sometimes too little. This can prevent the effective separation of residual solid impurities from the wastewater, leading to excessive accumulation of solid impurities in the separation tank. This can eventually cause the equipment to overload and stop operating, or the equipment to stagnate when the solid impurities accumulate to a certain level, affecting the treatment effect. Without a cleaning mechanism, solid impurities will accumulate and pile up on the bar screen, causing blockage, hindering water flow, reducing treatment efficiency, and potentially causing the equipment to stop operating.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through its quantitative discharge mechanism, solves the problem of excessive solid impurities accumulating in the separation box, which could eventually overload and stop the equipment, or cause the equipment to stagnate when solid impurities accumulate to a certain level, affecting the processing effect. The first motor output drives a threaded rod to rotate inside a fixed block, causing a connecting block to slide in a guide groove inside a first support plate. The guide groove supports and limits the connecting block. A connecting rod on the right side of the rotating connecting block rotates with a second hinge frame. The sliding connecting block and the sliding plate at the bottom of the second hinge frame cause a baffle to slide left and right, blocking the bottom of the guide box to achieve quantitative discharge. The first support block further blocks and limits the sliding baffle to prevent excessive movement and damage, effectively ensuring stable discharge of solid impurities, guaranteeing the normal operation and processing effect of subsequent equipment, and reducing equipment maintenance costs and operational risks.

[0014] 2. The design, consisting of a first filter plate, a first conveying pipe, a second filter plate, a connecting pipe, and a second support plate, effectively solves the problem of grid blockage, which obstructs water flow, reduces treatment efficiency, and may even cause equipment shutdown. When solid impurities fall into the guide box, they are separated from wastewater by the first filter plate. The separated wastewater then flows into the water tank through the first conveying pipe, where it is further filtered by the second filter plate inside the fixed ring in the water tank to remove smaller impurities. The filtered wastewater is then drawn into the pump output end on the second support plate via the inlet pipe. The wastewater and clean water are then transferred to the second conveying pipe and the second spray nozzle via the adapter pipe at the pump output end. The system uses a second conveying pipe to transfer water to the first spray pipe. Two first atomizing nozzles clean solid impurities from the first rake and prevent them from sticking to it. After the water is transferred to the second spray pipe, it is sprayed by the second atomizing nozzles to clean the surface of the first rake again, allowing solid impurities to slide into the separation tank through the guide plate. The water sprayed by the second atomizing nozzles flows into the separation tank and is then returned to the water tank through the first conveying pipe on the guide box at the bottom of the separation tank, thus achieving a recycling effect. This effectively ensures the normal operation of the screen, avoids excessive accumulation of solid impurities, and guarantees treatment efficiency and water purification effect.

[0033] like Figure 1 - Figure 8As shown, a water tank 19 is fixedly connected to the bottom of the machine body 1. The water tank 19 collects clean water. The front of the first conveying pipe 6 is connected to the rear wall of the water tank 19. Wastewater separated by the guide box 4 is discharged into the water tank 19 through the first conveying pipe 6. A fixing ring 20 is fixedly connected inside the water tank 19, and a second filter plate 21 is fixedly connected inside the fixing ring 20. The fixing ring 20 supports and fixes the second filter plate 21, further separating the wastewater delivered to the water tank 19. A connecting pipe 22 is connected to the right side wall of the water tank 19, connecting to an external pipe to transfer clean water. Water is discharged into water tank 19. A second support plate 23 is fixedly connected to the right side of the inside of water tank 19. A water pump 24 is installed on the top of the second support plate 23. The second support plate 23 is used to support and fix the bottom of the water pump 24. The input end of the water pump 24 is connected to the water inlet pipe 25. The water in the water tank 19 is drawn through the water inlet pipe 25 at the input end of the water pump 24. The output end of the water pump 24 is connected to the adapter pipe 26. The water is transported to the pipe through the adapter pipe 26 at the output end. A second support block 28 is fixedly connected to the front side wall of the machine body 1.

[0036] The output of the first motor 303 drives the threaded rod 304 to rotate inside the fixed block 305, which in turn drives the connecting block 306 to slide in the guide groove 302 inside the first support plate 301. The guide groove 302 supports and limits the connecting block 306. The connecting rod 308 on the first hinge frame 307 on the right side of the rotating connecting block 306 rotates with the second hinge frame 309.

The first support block 311 blocks and limits the left and right sliding baffle 312 to prevent excessive movement of the baffle 312.

[0037] When solid impurities fall into the guide box 4, they are separated from the wastewater by the first filter plate 5. The separated wastewater then flows into the water tank 19 through the first conveying pipe 6, and is filtered again by the second filter plate 21 inside the fixing ring 20 in the water tank 19 to remove smaller impurities. The filtered wastewater is then drawn in by the inlet pipe 25 at the output end of the water pump 24 on the second support plate 23. The wastewater and clean water are then transferred to the second conveying pipe 27 and the second spray pipe 31 through the adapter pipe 26 at the output end of the water pump 24. The water is then transferred to the first spray pipe 29 through the second conveying pipe 27. Two first atomizing nozzles 30 clean the solid impurities on the first rake 16 and the first rake 16 itself, preventing the device from sticking to the first rake 16. Water is transferred to the second spray pipe 31 and then sprayed through the second atomizing nozzle 32 to clean the surface impurities of the first rake 16 again, allowing the solid impurities to slide into the separation box 2 through the guide plate 17. The water sprayed by the second atomizing nozzle 32 flows into the separation box 2 and is then returned to the water tank 19 through the first conveying pipe 6 on the guide box 4 at the bottom of the separation box 2, thus achieving the effect of recycling. This effectively ensures the normal operation of the screen and avoids excessive accumulation of solid impurities.
