Type XZBG、XNBS、XNG Sediment Scraper,Concentrator by Peripheral

XZNBS-type peripheral drive scraper, thicker

 

XZNBS-type peripheral drive concentrator is mainly used for large (general water is greater than 600m3 / h, cell diameter greater than 20m) sewage treatment plant concentrated sedimentation tank, used to scraping pool body sedimentation sludge, the general surface also need to set scraping Slag scraper device.

Treatment process is generally the center of the water, the surrounding water, the center of mud.

In the center of the pool body is generally equipped with the central pillar of the inlet pipe, the lower part of the column tube and the pool body into the water pipe connection, the mouth closed as the center bearing platform, wall around the hole open water. Most of the central pillars are reinforced concrete structures, and steel structures can also be used.

 

Its characteristics

The use of hinged scraper to play the role of overload protection, and effectively reduce the investment costs;

The working bridge adopts truss beam, light weight, good rigidity, and the bridge length can be customized according to the different requirements of craft and site;

Scraper board pairs of spiral arrangement, improve the scraper effect, and the bottom of the wheel, can effectively prevent the jam;

Run the layer of mud, clean, thoroughly.

working principle

Sewage with a certain flow rate through the center of the steady flow into the sedimentation tank, with the flow rate decreases, the sewage in the inert and activated sludge settling in the bottom, the concentrator drive mechanism to promote the work of the bridge along the pool surface rotation, The scraper, which is rotated and fixed on the scraper, gradually sweeps the mud from the pool to the center of the pool, and the concentrated grille mounted on the scraper rotates to speed up the sludge settling. The sludge is discharged from the pool under the action of its own water pressure (or water pump). The scum floating on the surface of the water is collected by the skimmer installed in the surface of the concentrator and discharged into the hopper, the top water crosses the scum baffle, Through the water weir plate into the next process, in order to achieve the removal of sewage sludge and scum role.
