Drive around the half-bridge scraper main structure and working principle: half-bridge drive around the main bearing scraper from the center, draft tube, wiper arm bracket, bridge work, wiper arm and blade, skimming plate, scraping rake slag, slag bucket and flushing mechanism, side beams and drive mechanism, a weir plate, slag panels, control boxes and other components. Half-bridge drive around the main structure of a scraper, bridge work all of high quality carbon steel, designed as box-shaped structure, and to a certain Tigong, solid and reasonable, welding standards by JB / ZQ4000.3-86 "weldments General technical conditions. " 2. All parts are made of stainless steel underwater sewage treatment peripheral drive scraper, ensuring the life of the entire underwater parts. 3, with the overall design of the underwater scraper logarithmic helical blade scraper device peripheral drive scraper, scraper uniform efficiency. High peripheral drive scraper, scraper, wiper arm connection with the work of the bridge using a pin connection, when the precipitation amount is too large to automatically move the mud rake peripheral drive scraper price, to prevent damage to the blade. 4, the steady flow from the stainless steel tube using a diameter 3000mm, height 1500 upper and lower ends are configured arc angle made into strengthening the role. 5, the end of the beam all high-quality carbon steel welded drive mechanism using cycloid reducer by the size of the drive sprocket, drive wheel walk. 6, the machine set up dual mechanical and electrical overload protection device. Drive around the peripheral drive scraper scraper basically the same efficacy Center Drive scraper, is mainly used for large-scale (refer to the amount of water is greater than 600m3 / h, cell diameter greater than 20m) wastewater treatment plant and two primary sedimentation settling tank, scraping set bottom silt (specific gravity is generally less than 1.2 and less compaction), generally set the upper scum (or crema) scraping collection system, which has the function of scraping and downs, the process is generally the center of the water, surrounded by water, mud center. Peripheral drive scraper works drive to drive to work along the bridge pool plane rotation, driven scraper bridge work set to scrape the mud suction mouth, poor use of water will be sucked mud tank bottom sludge, sewage sludge tank Mud mud flows into the center of the cylinder, the exhaust outside the pool; also available through siphon sludge mud from the mud in the mud tank center cylinder exhaust inhalation. At the same time the pool was collected by scum scum bucket scraper to slag discharged outside the pool.
