Product Introduction of Rotary Drum Screen

BOEEP rotary drum screen is widely used in wastewater treatment projects such as urban wastewater, industry wastewater, food process industry, paper industry, municipal and so on. This equipment can remove scum, short fiber, and suspended matters from the wastewater intake, and then discharge them after pressing. It can be used for wastewater treatment engineering such as high precision process, small screen gap and low depth of channel.

Structure of Rotary Drum Screen

BOEEP rotary drum screen consists of the drum frame, screw press, conveying and pressing pipe, support, flushing device, electric cabinet, etc.

  • The screen net of the Rotary Drum Screen can clean by itself during operation. The equipment operates slowly,  hard objects can not damage the equipment, the screen net cannot be blocked, and there are nylon brushes in the inside of the screen net. The fine screen has the function of filtration, pressing, dewatering and transporting. The fully sealing structure can prevent the odor leaking. The equipment operates stably, the energy consumption is little, the noise is low, the grid gap is small, and through the fluid diversion, the separation efficiency can reach over 97%.

  • The Shaft Screw Conveying Presser of the Rotary Drum Screen can press and dewater the grid slag effectively. During the transporting, the water in the grid slag will flow out by the gravity.

  •  The underwater bearing adopts copper alloy sliding bearing. This bearing has the advantages of water resistance, corrosion resistance and wear resistance, and it can slide by itself in the water and does not need adding lubricating oil, which can ensure the equipment long-term operation without maintenance and prolong the service life of the Rotary Drum Screen.

  • The Rotary Drum Screen has the grid frame flushing system, and the flushing flow is controlled by the solenoid valve.

Working Principle of Rotary Drum Screen

The Rotary Drum Fine Screen has four functions such as intercepting dregs, getting rid of dregs, spiral lifting and pressing dewatering. It is mounted in the channel with the angles of 35 degrees, and the wastewater flows into the drum from the port of the drum, and the grid can intercept the dregs. Then the drum rotates at a fixed speed, and the nylon brush and flush water spray nozzle above the drum can get rid of dregs and export them through spiral lifting. The dewatered and pressed dregs will be delivered to the container or the transportation equipment. The whole process is clear and no smell.
