Description

Technical Field

[0001] This utility model relates to the field of mechanical bar screen technology, and in particular to a device for clearing blockages from mechanical bar screens. Background Technology

[0002] Mechanical bar screens are important pretreatment devices in wastewater treatment systems. They are mainly used to intercept and remove suspended solids, floating debris (such as branches, plastics, and fibers), and large particulate impurities from wastewater to protect subsequent treatment equipment from clogging or damage. Their core components include a set of parallel bars and a mechanical cleaning device. Driven by a motor, a toothed rake or rotating bar automatically scoops up the intercepted debris and transports it to a collection container, achieving efficient solid-liquid separation.

[0003] When using mechanical bar screens, a blockage removal device needs to be installed on top to remove debris stuck to the screen. A search revealed a patent with publication number CN219290815U that discloses a blockage removal device for mechanical bar screens. This device uses a structure to transport drainage through a suction pipe and connecting pipe into a flow channel, and finally sprays it outwards at high pressure through multiple spray channels. As the movable rod rotates, the high-pressure sprayed drainage can be sprayed onto the transmission components and toothed rakes. The high-pressure drainage sprayed outwards from the spray channels, combined with the beating and brushing action of the cleaning brush, removes debris. However, the water spray in this device needs to exit from inside the movable rod, making the initial design and manufacturing of this part complex. Furthermore, the cleaning brush is not quick and convenient to assemble and disassemble; once wear occurs between the cleaning brush and the screen, replacement is inconvenient. Therefore, further improvements are needed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a mechanical bar screen clearing device is disclosed, comprising a U-shaped frame 1 and two mounting plates 9. The top of the U-shaped frame 1 is rotatably connected to a rotating shaft 2 via a bearing. A motor 6 is fixed to the outer surface of the U-shaped frame 1. The rotating shaft 2 is fixedly connected to the output end of the motor 6. A rotating cylinder 3 is fixed to the surface of the rotating shaft 2. Multiple clearing components 4 are attached to the surface of the rotating cylinder 3. Two connecting components 5 for installing the clearing components 4 are fixed to the surface of the rotating cylinder 3 and on both sides of each clearing component 4. A flushing component 7 is fixed to the bottom of the U-shaped frame 1. Connecting brackets 8 are fixed between the two ends of the U-shaped frame 1 and the two mounting plates 9, respectively.

[0024] The interior of the rotating drum 3 is hollow.

[0025] In this embodiment, by designing the rotating drum 3 as a hollow shape, the weight of the entire device can be reduced, making it easier to install and use.

[0026] The cleaning component 4 includes a strip plate 41 that is attached to the surface of the rotating drum 3. Brush bristles 42 are fixed on the surface of the strip plate 41, and perforations 43 are provided at both ends of the strip plate 41 near the connecting component 5.

[0027] When the cleaning component 4 is fixed on the surface of the rotating drum 3, the motor 6 drives the rotating shaft 2 and the rotating drum 3 to rotate, thereby driving the cleaning component 4 to rotate. The bristles 42 on the cleaning component 4 are used to clean the blockage stuck on the grid, so as to avoid grid blockage.

[0028] The connecting component 5 includes an insert block 51 fixed to the surface of the rotating drum 3. The insert block 51 has a groove 52 on the side wall of one end of the through hole 43. A spring 53 is fixedly connected to the inner side wall of the groove 52. A locking tooth 54 is fixedly connected to the other end of the spring 53. The end of the locking tooth 54 located outside the groove 52 is engaged with the surface of the strip plate 41.

[0029] In this embodiment, the top of the retaining tooth 54 located outside the groove 52 is designed with an angled surface. The strip plate 41 matches and fits the arc surface of the rotating cylinder 3. When installing the cleaning component 4, the strip plate 41 is directly attached to the surface of the rotating cylinder 3, so that the insert block 51 passes through the corresponding through hole 43 on the strip plate 41. The inner wall of the through hole 43 will first squeeze the retaining tooth 54 back into the groove 52. After the retaining tooth 54 has completely passed through the through hole 43, the spring 53 squeezes the retaining tooth 54 to pop out of the groove 52, so that the retaining tooth 54 is locked on the surface of the strip plate 41, thereby achieving the fixed installation of the cleaning component 4. When disassembling the cleaning component 4, the retaining tooth 54 is first squeezed back into the groove 52, and then the strip plate 41 can be moved along the insert block 51 to the side away from the rotating cylinder 3, thereby achieving the disassembly of the cleaning component 4.

[0030] The rinsing assembly 7 includes a water pipe 71 fixed to the bottom of the U-shaped frame 1. The water pipe 71 is connected to a water pump. Several high-pressure nozzles 72 are fixed at equal intervals on the surface of the water pipe 71, and the high-pressure nozzles 72 are inclined toward the cleaning assembly 4.

[0031] When the motor 6 drives the cleaning component 4 to rotate and clean the grille, water is pumped to the water pipe 71 by the water pump. The water is sprayed out from the high-pressure nozzle 72 to rinse the cleaning position of the brush bristles 42, further cleaning the grille.

[0032] The connecting frame 8 includes a square tube 81 that is fixedly connected to the mounting plate 9, and an L-shaped rod 82 is slidably connected inside the square tube 81. A sliding sleeve 83 is slidably connected to the vertical surface of the L-shaped rod 82. The sliding sleeve 83 is fixedly connected to the U-shaped frame 1 by bolts. The mounting plate 9 is fixedly connected to the frame of the bar screen machine by bolts.

[0033] The side wall of the sliding sleeve 83 is penetrated and connected by a first fastening bolt 84 via a threaded connection, and the side wall of the square tube 81 away from the mounting plate 9 is penetrated and connected by a second fastening bolt 85 via a threaded connection.

[0034] During installation, the mounting plate 9 is first connected to the frame of the bar screen machine. Then, the L-shaped rod 82 is moved along the square tube 81 so that the U-shaped frame 1 moves closer to the bar screen. Then, the brush 42 of the cleaning component 4 is brought into contact with the bar screen by moving the sliding sleeve 83. Finally, the first fastening bolt 84 and the second fastening bolt 85 are tightened to fix the sliding sleeve 83 and the L-shaped rod 82.

[0035] Therefore, when it is necessary to disassemble and replace the cleaning component 4, the first fastening bolt 84 and the second fastening bolt 85 can be loosened, and the sliding sleeve 83 and the L-shaped rod 82 can be moved away from the grid, so that the U-shaped frame 1 is away from the grid, providing more space for the disassembly and assembly of the cleaning component 4, making the disassembly and assembly of the cleaning component 4 more convenient.

[0036] Working principle: The starting motor 6 drives the rotating shaft 2, rotating drum 3 and cleaning component 4 to rotate. The brush bristles 42 clean the garbage and debris stuck on the screen. At the same time, the water pump connected to the water pipe 71 is started, and the water sprayed from the high-pressure nozzle 72 rinses the area cleaned by the brush bristles 42, further cleaning the screen.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
