1、Advantages of non-metallic chain plate type sludge scraper:
★The density of the used material is similar to that of water, or the buoyancy of components is designed to be similar to weight, less abrasion, corrosion resistance, and long service life.
★Low power consumption, a 70M*8M sedimentation tank, the power consumption is only 0.37KW;
★Compared with the circular pond, the area covered is small, it can use a double layer construction method;
★The concentration of outlet sludge is high, which can save more raw water;
★Simple installation, no special tools required, basically no maintenance is required;
★Adaptable to the technical innovation of old-fashioned sedimentation tank, major civil adjustment is not required.
The application of non-metallic chain plate type sludge scraper:
It is usually installed in primary sedimentation tank and secondary sedimentation tank, and the scraper operates at the bottom of the pool, which collects the sludge to one side of the pool and discharge it. During the reverse running, the scraper collects the scum to the scum pipe on the other side and discharge it. 4 chain wheels are installed on each side of the wall of sedimentation pool by the system.
It is used to collect the sediment on the bottom of the tank, the chain and scraper can be carried out inspection and maintenance on or above the surface of the water, and 3 chain wheels are installed on each side of the wall of sedimentation pool by the system.
It is usually installed in the bottom of sedimentation tank or inclined plate sedimentation tank with inclined plates, water pipes, or other obstacles for sludge collection. 2 chain wheels are installed on each side of the wall of sedimentation pool by the system.
