Surrounding transmission scraper

central drivescraperDuring operation, it should be noted that the machine is equipped with an overcurrent protection device. Once a fault occurs, the machine can be stopped immediately to protect the safety of the motor. After parking and troubleshooting, if it is difficult to start again, push the scraper and suction machine before starting the motor. The scraper suction machine operates continuously. After a prolonged shutdown due to a malfunction, the sewage in the tank must be emptied and the deposited sludge manually removed before it can be put back into use.

The structure of the peripheral transmission scraper suction machine is different from other types of scraper suction machines. Its bridge rotates around the central axis, and the driving device is installed at both ends of the bridgescraperThe scraper and bridge are fixed together by brackets. Peripheral transmission can optimize the stress condition of the scraper suction machine and help increase its service life.

The sludge discharge device of the central transmission scraper suction machine is based on the principle of connecting pipes, using the liquid level difference to scrape and collect the activated sludge settled at the bottom of the tank, and automatically press it into the sludge discharge tank. The sludge in the sludge discharge tank flows automatically into the central mud tank, and then is discharged outside the tank through the central mud drum and discharge pipe. During the major maintenance of the central transmission scraper suction machine, it is necessary to check the corrosion of underwater components, the sealing condition of each sealing element, and the wear of rubber scrapers; During major maintenance, it is necessary to follow thescraperThe anti-corrosion coating required by the construction drawing shall be re applied for anti-corrosion.

central drivescraperIt is mainly composed of supporting accessories such as bridge frame, reduction motor plate, suction pipe, central mud collection tank, slag skimming device steel water outlet tank, water outlet weir plate, etc. The central slewing support, steady flow cylinder, frame steel structure, arm frame, and on-site control box for mud collection scraper can be used. The steel inlet column pipe and stainless drive device can be equipped with worm gear reduction motor and built-in compression spring type over torque protection mechanism; The drive motor adopts a Y-shaped motor, with a power supply of 3P, 380V, 50HZ, protection level of IP55, and F-class insulation; During operation, each suction pipe forms its own unit, and the suction concentration can be controlled by a flow regulating valve located in the central collection tank. The local control box is outdoor, with a stainless steel shell, double-layer door sealing, manual and remote control.

Main performance:

(1) The bottom of the pool is scraped with mud, and the driving device adopts a deceleration driving mechanism for transmission, with a compact structure and high mechanical efficiency;

(2) Diagonal scraper with good continuity and high efficiency in collecting mud; Install a scraper rubber plate under the stainless steel scraper plate to ensure that the scraper is clean and there is no floating mud phenomenon.

(3) The slope ratio of the pool bottom is 1:10, and the sludge resistance during scraping can be ignored.

(4) The main beam is made of square steel with high structural strength. It adopts hot-dip galvanizing and then spray coating technology, which has strong anti-corrosion performance. The main beam can also be directly poured with concrete, which saves more investment.

(5) Easy to operate and capable of remote control.
