As an important equipment of sewage treatment project, rotary drum screen is also the primary link of sewage treatment system, so its construction is very important. Considering the protection of the rotary drum screen, it is installed after the completion of the civil main body. The installation considers the use of automobile crane and electric hoist to cooperate with the installation. The whole machine is hoisted when the equipment is installed. During the transportation process, the hanging point is on the two lugs in the middle of the rotary drum screen.

The rotary drum screen is firstly hoisted on the guide rail of the platform. After sliding to the channel position by the trolley, the electric hoist is used to take the two lifting lugs on the upper part of the rotary drum screen as the lifting point. The lifting rope and the guide chain must be hung and laid free so that they can bear the force freely. When installing, the equipment should be horizontal with the ground, slowly down the grille, when down to the two main legs fixed in advance, the drum grille gently tilt again, adjust the inclination angle to 35 degrees when the fixed floor, be careful not to touch the top drive device.

After the rotary drum screen is installed, rubber sheets are applied to both sides of the rack and channel for sealing to prevent water from passing through the gap. Special attention should be paid to ensuring the performance requirements of the equipment and controlling the quality accuracy of the parts in the installation process. At the same time, the frame platform of the main part of the transmission system should be processed after welding in order to improve the assembly accuracy of the transmission system.http://www.khnwatertreatment.com/
