The mechanical grill is a grill device that can automatically remove the garbage attached to the grill.Mechanical grille is one of the early purification equipments in water supply and drainage treatment technology.It greatly reduces the labor intensity of workers, protects workers' health, reduces the head loss of incoming water, and improves the efficiency of pumping stations.
Working principle Schematic diagram of rotary mechanical grid Schematic diagram of rotary mechanical grid It consists of many identical rake tooth parts staggered and assembled into a set of closed rake tooth chains, driven by the motor and reducer, through a set of sheave and The chain forms a continuous top-to-bottom cyclic movement to achieve the purpose of continuously clearing the grille.When the rake tooth chain runs to the upper and back of the equipment, due to the guiding effect of the sprocket and the curved rail, the parallel rake tooth row can be dislocated, so that the solid dirt falls into the slag tank by its own weight, and when it falls off uncleanly, the Grilles tend to carry dirt into the channel behind the grille.When the mechanical grille of the wire rope traction drum is working, the wire rope driving device releases the rope, and the rake bucket descends along the guide rail from the highest position (the end of the last cycle of slag skimming), and the slag skimming plate descends with the rake bucket under the action of its own weight.When the skimmer is reset, the rake bucket is opened by the traction of the middle wire rope under the push of the opening and closing rake device (electric push rod) and continues to descend until it reaches the lower limit of the channel. After the rake teeth are inserted into the grid gap, the wire rope The driving device retracts the rope to further force the rake bucket to be completely closed. After the rake bucket and the trolley go up the guide rail, the slag is removed until it touches the slag skimming plate. The slag tank completes a working cycle.
