LZ type three cable steel wire rope cleaning grid machine

　　purpose

The LZ type three cable steel wire rope decontamination grid machine (referred to as the steel wire rope decontamination grid machine) is suitable for large and medium-sized water plants, rainwater/sewage lifting pump stations, sewage treatment plants, and power plant water inlets to intercept and remove coarse floating objects and bottom sediments in water, protect the water pump impeller, and reduce the processing load of subsequent process equipment.

Structure and working principle

The rack of the equipment is fixed at the upper end of the wellhead and consists of fixed bars to form a water passing grid surface. When sewage flows through the grid surface, debris larger than the grid gap is intercepted: the rake bucket is first driven by a motor, completes the flipping action and stops, then driven by a lifting motor and controlled by a height limiter. It descends along the two side guide rails to the bottom of the grid well and stops, and automatically starts the flipping motor again. After completing the closing action, it stops, and the lifting motor starts again. The rake bucket is pulled by a steel wire rope and inserted into the gap between the bars to scoop up the intercepted debris, which rises along the grid surface and slag baffle. Under the control of the height limiter, when it reaches the discharge port position, the lifting motor stops, and the cleaning at the upper rack is carried out. The dirt scraper automatically scrapes away debris with the upward movement of the scraper bucket, and falls into the conveyor or garbage truck from the discharge port, The cleaning process is completed in one go.

Main features

1. The frame structure is unique and adopts a split type design, meaning that the upper frame and lower grille assembly are not integrated;

2. The rake bucket adopts a dedicated large capacity, heavy-duty "grab bucket type", which is guided by rollers on both sides and pulled by steel wire ropes to ensure smooth operation;

3. There is a discharge scraper plate on the upper rack, which can effectively scrape the dirt in the rake bucket to the discharge port and discharge it thoroughly and cleanly;

4. The lifting and opening of the rake bucket are two independent driving systems, which operate according to the set program under the control of the electrical system;
