Independently designed with reference to core technologies of imported equipment, it is listed as a National Torch Program Project (No. 2003EB060572), Provincial High-tech Product (No. 030282G0080N), and holds a national utility model patent (Patent No. ZL 02 2 60164.3).</p><p>This machine is widely applied in municipal sewage, industrial wastewater, food processing, papermaking and other wastewater treatment projects. It captures and removes floating debris and sediment at water intake points, then squeezes and dewaters screen residues before discharging them.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; flex: 0 1 auto; flex-direction: row; justify-content: normal; align-items: normal; margin: 0px; background-image: none; background-position: 0% 0%; background-size: auto; background-repeat: repeat; background-attachment: scroll; background-origin: padding-box; background-clip: border-box;">Structure & Working Principle</h2><p>The equipment is installed in the water channel at a 35° angle to the horizontal plane. Wastewater flows into the drum from the front end, then permeates outward through slits on the drum sidewall. Suspended solids and floating trash are intercepted inside the rotating drum.The drum rotates at a fixed speed. Nylon brushes and flushing nozzles mounted on the top strip off trapped screen residues, which are then conveyed, squeezed and dewatered by the built-in screw conveyor, and finally transported to the top discharge hopper for removal.</p><h2 style="font: 400 16px / 24px ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji";

Wastewater flows through the open inlet of the screen and passes through the screen bars into the channel, where solid contaminants are intercepted by the bars.When a certain water level difference forms, rotating rakes mounted on the central shaft revolve inside the drum. Upon reaching the highest position, all screen residues drop into the central screw trough. A built-in screw conveyor and press inside the trough squeezes and dewaters the residues, then transports them upward to the top discharge outlet.</p><hr style="color: rgb(0, 0, 0); font-style: normal;
