The central transmission structure is generally used to scrape the bottom sludge of various circular sedimentation tanks with a tank diameter of less than 18m (generally the water volume of a single tank is less than 600T/). Normally, the central sludge is discharged and water is discharged from the periphery.ZXG central drive sludge scraper is generally used for municipal sewage and similar sewage. The specific gravity of sludge is relatively light (generally less than 1.2T/m) and non-hardening pool bottom sludge. Generally, there is no scum scraping function, and a slope can be installed in the pool. Plate or inclined tube to improve precipitation effect.
The ZXN center drive concentrator is similar to the ZXG type. It is mainly used to further thicken the sludge discharged from the ordinary sedimentation tank. The structure has an additional grid section (increasing the compactness of the sludge) compared with the sludge scraper.
Working bridge structure: Steel beam type should be used if the pool diameter is less than 10 meters, and truss beam should be used if the pool diameter is greater than 10 meters.
