The fine screen is a grid that can be automatically and automatically removed. It is assembled in a staggered parallel assembly of a plurality of identical molars into a set of closed jaw chains. Driven by the motor and reducer, a series of sheaves and chains form a continuous top-down cycle motion to achieve the goal of continuously clearing the grille.

When the dent chain runs to the upper part and the back of the equipment, due to the guiding action of the sprocket and the curved rail, the parallel dent rows can be misaligned, so that the solid dirt falls into the slag tank by its own weight, and when the detachment is not clean, the machine The grille tends to carry dirt to the rear channel.

When the wire rope traction reel, fine screens is working, the steel rope drive device releases the rope, and the bucket descends from the highest position along the guide rail, and the slag slag plate descends with the bucket under the action of its own weight. After the slag board is reset, the bucket is pulled by the middle steel rope by the opening and closing device and continues to descend until reaching the lower limit of the channel. After the dent is inserted into the grid gap, the steel rope drive device collects the rope. After the forced bucket is completely closed, the bucket and the bucket move up along the guide rail to clear the grid slag until it touches the slag plate. Under the relative movement of the two, the grid slag is thrown out, and the slag plate falls into the slag tank to complete a Work cycle.

Such fine screens are widely used in the water inlets of water supply plants, the cooling water inlets of power plants, the screening of raw wool scouring and washing, the screening of debris in municipal pipe channels, and the treatment of urban and community sewage. Pre-screening and pre-screening of woven printing and dyeing wastewater, chemical wastewater, slaughter wastewater, fur tanning wastewater, and papermaking wastewater treatment to prevent clogging of pumps.
