main purpose
The barrier free cleaning machine is fixedly installed at the inlet of hydraulic structures such as pump stations, power stations, and inverted siphons. It intercepts the pollutants (branches, leaves, weeds, household waste, floating ice, etc.) carried by the water flow with a trash rack, and uses a rotating toothed rake to scoop them onto the bridge deck, which is transported away by a belt conveyor or other means to prevent harmful pollutants from entering the water intake, ensuring the smooth operation of the unit or other equipment and structures.
The machine has a simple structure, good rigidity, smooth operation, low risk of failure, easy operation and maintenance, good cleaning effect, high efficiency, low energy consumption, and long service life
structural characteristics
An accessible cleaning machine is a fixed continuous cleaning equipment that combines interception and cleaning. It mainly consists of three parts: grid body, cleaning rake (toothed rake), and transmission system; According to the situation of pollutants at the bottom of the diversion channel, auxiliary grids are sometimes added at the bottom of the grid body.
working principle
The driving device is directly installed inside the grid body of the cleaning machine, eliminating the transmission bracket and space barriers caused by the transmission bracket and reducer, ensuring smooth cleaning work and improving cleaning efficiency. The active sprocket on the output shaft of the reducer drives the driven sprocket on the wheel axle group through chain transmission, and the driven sprocket transmits torque to the wheel axle transmission shaft through a safety protection device. The transmission shaft drives two traction sprockets to rotate, thereby rotating the traction plate roller chain. The cleaning rake installed between the two traction chains rotates with the chain. Due to each rake tooth being inserted into the grid surface to a certain depth, the dirt on the grid surface is forced to move with the rake. When the rake rotates to the top of the grid body and the traction chain changes direction, the rake also flips over. At this time, the dirt on the rake falls off to the working bridge deck or belt conveyor facilities and is sent out of the bridge deck.
Transmission system
The transmission system mainly consists of an electric motor, a planetary cycloidal pinwheel reducer, an active sprocket, a drive chain (sleeve roller chain), and a wheel axle group. The wheel axle assembly consists of a driven sprocket, a transmission shaft, a traction sprocket, a plate roller chain, left and right adjustable bearings, and an overload protection mechanism. The tension of the drive chain is tightly attached to the sliding rail and adjusting bolt on the motor seat for adjustment. The traction sprockets at both ends of the transmission shaft supported on the left and right adjustable bearing brackets mesh with the plate roller chain, causing the roller chain to rotate around the guide rail. To synchronize the tension of the two roller chains, adjustment screws are installed on the left and right adjustment bearings.
