Working Principle of External Rotary Drum Screen
The drum does the rotary movement by the driving device, and the sewage is moved from the inlet pipe into the filtrate tank, then flow out. The solid materials are intercepted by screen,and the water is drained out into the pool from the gap of the screen. The cylinder continuously rotates,and the solid substances attached to the outer wall of the screen quickly peel off from the drum.The backwashing system is composed of a flushing line and nozzles. The high pressure water is sprayed through the nozzles, and the solid objects attached to the sieve is flushed out quick ly.The filtration is continuous and non clogged. The external rotary drum screen has the characteristics of high efficiency, large throughput and fine filtration.

Advantages of External Rotary Drum Screen
• Compact structure, small footprint.
• Simple structure, high reliability.
• The surface of the drum is made of wedge grid,and has
excellent hydraulic characteristics.

Product Details:

 

This machine is used for the separation and subsequent dewatering and compacting of the solid content in wastewater coming from industrial and municipal Effluent Sewage plants.

JAGTAP Inclined Rotary Drum Screening Machine is composed of the drum assembly, screw shaft, conveying and pressing pipe, support. flushing device, electric cabinet. etc.

1. The screen net of the inclined rotary drum screening machine 
can clean by itself when operation. The equipment operates 
slowly, gravel and hard objects do not damage the equipment. 
the screen filter 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 noise is low, the 
grid gap is small, the energy consumption is little, and through 
the fluid diversion, the separation efficiency can reach over 
97%.

2. The shaft screw conveying presser of the inclined rotary drum 
screening machine can press and dewater the grid 
effectively. During the transporting, the water in the grid slag 
will flow out for its gravity.

3. The underwater bearing adopts copper alloy sliding one. 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.
4. The inclined rotary drum screening machine has the grid frame
flushing system, and the flushing flow is controlled by the 
solenoid valve.

Working Principle

The inclined rotary drum screening machine 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 brush and flush water spray nozzle above the drum can get rid of dregs and export them through spiral lifting.
The whole process is clear and no smell.
