Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically a rotary bar screen cleaning device for sewage treatment. Background Technology

[0002] In the field of wastewater treatment, traditional bar screen cleaning devices are mainly used to intercept and remove large impurities in wastewater to prevent them from entering subsequent treatment equipment and causing blockages or damage. However, existing bar screen cleaning devices have the following problems: traditional bar screen cleaning devices mostly operate intermittently, resulting in low operating efficiency and an inability to continuously and efficiently remove impurities from wastewater; traditional devices are mostly made of metal, which is prone to corrosion and rust when immersed in wastewater for a long time, resulting in a short service life and increased equipment replacement costs. Furthermore, bar screens cannot be manufactured as a single unit before leaving the factory for quick on-site disassembly or installation, making existing bar screen cleaning devices inconvenient for personnel maintenance and cleaning. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotary bar screen cleaning device for sewage treatment, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A rotary bar screen cleaning device for sewage treatment includes a concrete base, a water tank inside the concrete base, an inclined surface on the top of the concrete base, and a mounting seat fixedly mounted on the top of the concrete base at both the front and rear. The mounting seat is characterized by having multiple rollers rotatably mounted on one side, a rotating ring on another side, the rotating ring rolling against the rollers, and sleeves fixedly connected between the rotating rings. A clamping ring plate is fixedly mounted on the outer surface of the sleeve at both the front and rear, and multiple connecting plates rotatably mounted on the outer surface of the sleeve. The connecting plates are arranged crosswise and located on both sides of the sleeve, and the connecting plates are rotatably connected to adjacent sleeves. An annular portion is fixedly mounted between the connecting plates, and a claw portion is fixedly mounted on one side of the annular portion. The clamping ring plates press and fix the annular portion and the connecting plates. A power assembly for driving the rotating rings to rotate is mounted on the mounting seat.

[0005] In a further technical solution, the rotating ring has a circular structure, and the outer arc surface of the roller rolls against the inner ring of the rotating ring.

[0006] In a further technical solution, the outer surface of the roller is provided with a groove.

[0007] A further technical solution includes a power assembly comprising a geared motor fixedly mounted on the upper side of the mounting base, a drive gear being poweredly connected to the output shaft of the geared motor, and a gear ring being fixed to the outer surface of the rotating ring, the gear ring being meshed with the drive gear.

[0008] In a further technical solution, a plurality of fixed posts are fixedly provided on one side of the rotating ring, and a rectangular block is fixedly provided on one side of the fixed posts, with an inner hole provided inside the rectangular block.

[0009] In a further technical solution, the sleeve has a rectangular hole at the front and a rectangular hole at the back, and a sleeve hole is provided in the rectangular hole. The rectangular block is inserted into the rectangular hole, and the sleeve hole is opposite to the inner hole of the rectangular block.

[0010] In a further technical solution, the clamping ring plate is provided with multiple through holes, and the through holes are provided with column inner holes. The sleeve is inserted into the through holes, and the column inner holes are arranged opposite to the sleeve holes. The clamping ring plate, the sleeve, and the rectangular block are connected and fixed.

[0011] In a further technical solution, a mounting shaft is fixedly provided on the outer surface of the sleeve, and multiple key blocks are fixedly provided on the outer surface of the mounting shaft. A mounting hole is provided in the annular portion, and multiple keyways are provided in the mounting hole. The key blocks abut against the keyways, and the mounting shaft is sleeved in the mounting hole, so that the annular portion and the claw portion are dynamically connected to the mounting shaft.

[0012] In a further technical solution, a circular hole is provided in the connecting plate, and an arc is provided on the end face of the key block. The key block abuts against the circular hole, and the connecting plate rotates around the outer surface of the key block.

[0013] In a further technical solution, multiple connecting plates and annular portions are alternately arranged, and the connecting plates and annular portions are fixed to the outer surface of the mounting shaft by the clamping ring plate.

[0014] The beneficial effects of this utility model are as follows: First, by forming an integrated structure with a rotating ring, a toothed ring, a fixed column, a clamping ring plate, a sleeve, a mounting shaft, an annular part, a hook part, and a connecting plate, the roller abuts against the inner ring of the rotating ring, and the driving gear meshes with the toothed ring. This allows the reduction motor to drive the driving gear to rotate, thereby causing the rotating ring to rotate in a ring. The staggered annular part, hook part, and connecting plate provide good water permeability, and the hook part can scoop up impurities in the water and pour it onto the inclined surface by centrifugal force. Because it adopts continuous rotation operation, the working duration is relatively long.

[0015] Second, for the integrated structure of rotating ring, toothed ring, fixed column, clamping ring plate, sleeve, mounting shaft, annular part, hook part and connecting plate, the whole can be installed before leaving the factory.

On-site assembly and installation are avoided, and it can be directly disassembled and replaced, which is very convenient.

[0016] Third, through the structural design of mounting holes, keyways, key blocks, mounting shafts, and sleeves, the annular part and the claw part can be firmly fitted onto the outer surface of the mounting shaft. When the outer surface of the key block is arc-shaped, the circular hole in the connecting plate is rotatably connected with the arc surface of the key block, so that the connecting plate can rotatably connect adjacent mounting shafts. The detachable connection method allows for disassembly and cleaning during maintenance, replacement of damaged parts during maintenance, and thorough cleaning of dirt after disassembly.

[0037] When the device is running, sewage is introduced into the water tank 11. After the device is running, large debris in the sewage is centrifugally thrown to the lower right by the rotating structure and piled up on the inclined plane 13. Personnel can clean the debris on the inclined plane 13 regularly.

[0038] Roller 23 supports rotating ring 24 and causes rotating ring 24 to roll on the outer surface of roller 23 as it rotates.
