Description

Technical Field

[0001] The utility model relates to the technical field of rotary grille dirt removers, in particular to a grille dirt remover which is easy to assemble and disassemble. Background Art

[0002] The rotary screen cleaner is a preliminary treatment equipment for domestic sewage purification. It is installed at the inlet of the pump station collection tank and performs a rotary motion against the direction of water flow to intercept large pieces of suspended or floating solid pollutants to avoid clogging the pump and the mud discharge pipe of the sedimentation tank. When the rotary screen cleaner is working, the motor drives the active guide wheel to rotate, and the active guide wheel drives the chain and the driven guide wheel located in the underwater working area to move. There are several rake teeth on the sprocket. The rake teeth move with the sprocket, hook the underwater debris and move upward, relying on gravity to remove the dirt to the conveying device, and the conveying device transports the debris away.

[0003] However, the existing screen cleaner has the following two problems in actual use: on the one hand, the rake teeth are connected to the chain plates of the opposite chain, and as a wearing part, it is not convenient to disassemble and assemble it; on the other hand, the solid pollutants intercepted by the rotary screen cleaner accumulate at the discharge port, making it difficult to clear and dredge.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a grille dirt remover that is easy to disassemble and assemble is proposed. Utility Model Content

[0005] The utility model aims to provide a grille dirt remover which is easy to disassemble and assemble, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grille dirt remover that is easy to disassemble and assemble, comprising a dirt remover frame and a disassembly and assembly component, the dirt remover frame is provided with a disassembly and assembly component, the disassembly and assembly component comprises a connecting roller, a slot, a screw, a mounting plate, a threaded hole and a tooth rake, a slot is provided in the middle of the connecting roller, and screws are provided at both ends of the slot, a mounting plate is plugged into the slot, and threaded holes are provided at both ends of the mounting plate, and a tooth rake is arranged at the front end of the mounting plate along the extension direction.

[0007] Furthermore, a gap is left between adjacent tooth rakes at the front end of the mounting plate, and the rear end of the mounting plate is fixed to the screw rod through a threaded hole.

[0008] Furthermore, a conveyor bracket is arranged below the discharge port of the dirt remover frame, and a funnel-shaped material dropping opening is opened on the top of the conveyor bracket.

[0009] Furthermore, a motor 1 is fixed by bolts on the side of the conveyor bracket, and a spiral auger is fixedly connected to the output end of the motor 1.

[0010] Furthermore, a slag supporting plate is fixedly installed inside the dirt remover frame, and a second motor is fixed by bolts on the top of the dirt remover frame.

[0011] Furthermore, the second output roller of the motor is engaged with a traction chain, and the traction chain is rotated away from the second output roller of the motor to transmit a sprocket main shaft.

[0012] Furthermore, a transmission chain is engaged with the outside of the sprocket main shaft, and connecting rollers are connected between the opposite transmission chains.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, the second motor drives the sprocket main shaft located on the top of the dirt remover frame through the traction chain engaged by the output roller, and the sprocket main shaft further drives the transmission chain and the driven guide wheel located in the underwater working area to move. A number of tooth rakes are arranged at equal intervals on the transmission chain. The tooth rake moves with the transmission chain to lift the intercepted dirt out of the water surface. When it moves to the slag outlet, the tooth rake automatically turns over with the movement of the transmission chain, and the dirt falls into the funnel-shaped blanking opening reserved on the top of the conveyor bracket. Under the action of the spiral auger at the output end of the first motor, the dirt is cleared and transferred in time to avoid the accumulation of dirt at the slag outlet and the blockage of the rotary grille dirt remover.

[0015] 2. The utility model provides a disassembly and assembly component. When disassembling and replacing the tooth rake, which is a wearing part, it is only necessary to unscrew the screws at both ends of the connecting roller and pull the mounting plate out of the slot. After that, the replacement part is inserted into the slot again, and the rear end of the mounting plate is fixed to the screw through the threaded hole. The tooth rake can be quickly disassembled and assembled, and the operation is convenient, which shortens the downtime of the rotary screen dirt remover. BRIEF DESCRIPTION OF THE DRAWINGS
