COA drum grille decontamination machine
product description
COA rotary drum grille decontamination machine is a kind of equipment that integrates a fine grille decontamination machine, a slag removing screw elevator and a slag removing screw press. Scope of application The fine grille suitable for urban sewage treatment plants is a device that integrates the interception, transportation and pressing of slag and dirt. Outstanding advantages 1. The whole machine has compact structure, small floor space, easy installation, operation and maintenance; 2. The equipment grid has a small gap, which can generally be designed in the range of 6~12mm; 3. High pollution interception efficiency, enclosed transportation, no pollution to the environment; 4. The equipment can be fully automatically controlled, with stable operation, low energy consumption and low noise; 5. Automatic cleaning is carried out during the operation of the equipment, and it will never be blocked. working principle Sewage (or other raw water) is transported by a water pump, enters the internal water distribution tank of the drum grid from the water inlet pipe (tank), overflows by gravity, and flows through the filter surface of the drum grid. The larger solids or fibers are It is trapped in the rotating drum, and gathered and moved to the outlet of one end of the rotating drum through the action of the inner spiral plate, and falls into the trough. The rotating drum has a recoil spray pipe that can run continuously or intermittently to remove impurities that may adhere to the drum surface and prevent the grid surface from clogging. The drum grille is driven by a gear reducer and a chain, and the rotating speed is adjusted by a frequency converter. The filter surface of the drum can be selected as perforated plate, metal mesh, wedge-shaped grid forming mesh, suitable for different occasions.
