Coal washing sewage treatment mechanical equipment Horizontal screw centrifuge It is a kind of equipment used to treat sewage generated during coal washing. Coal washing wastewater usually contains coal gangue, slime and other solid particles, as well as organic and soluble substances. Recumbent snail Centrifuge The solid matter in the sewage is separated from the liquid by the action of rotating centrifugal force.
The working principle of horizontal screw centrifuge mainly includes the following steps:
1. Feeding: the coal washing sewage is input into the equipment through the feeding port.
2. Spiral concentration: the solid particles will gradually deposit on the wall of the screw conveyor when the sewage passes through the screw conveyor in the centrifuge, and the liquid will flow out through the center of the screw conveyor.
three Solid-liquid separation : The solid particles on the screw conveyor will gradually push to the centrifugal chamber with the rotation of the equipment, and the liquid in it will be squeezed out by the centrifugal force.
4. Solid discharge: Centrifuge periodically discharges solid substances in sewage, namely coal gangue, slime and other solids.
The horizontal screw centrifuge, a mechanical equipment for coal washing wastewater treatment, can efficiently separate the solid particles and liquid in the coal washing wastewater, so that the wastewater can meet the national discharge standards or achieve recycling. It can help the coal washing plant reduce the consumption of water resources, improve the environmental friendliness of coal production, and protect the surrounding environment from pollution.
