Detailed introduction


Application occasions

ZBG and BZBG peripheral drive mud scrapers are mainly used in the primary and secondary sedimentation tanks of large (generally referring to water volume greater than 600m ³/h and tank diameter greater than 20m) sewage plants to scrape mud at the bottom of the collection tank (specific gravity is generally less than 1.2 and is not easy to compact). Generally, there is no scum (or froth) scraping system at the upper part, and the scum scraping functions. The process is generally for the center and the periphery, center mud discharge.

Model representation

Features

The hinged wiper arm is used for overload protection and effectively reduces operating costs.

The working bridge normally adopts truss beam, which is light in weight, good in rigidity, and the bridge length can be determined according to the process requirements.

Logarithmic spiral mud scraper, and the bottom is equipped with rollers, effectively prevent blocking.

Ordering Instructions

1, according to the application combined with the process requirements of reasonable selection, indicate the model specifications and pool depth, pool bottom slope and other parameters, do not indicate that according to the table value of half bridge order.

2. The central flow stabilizing cylinder, scum baffle (baffle plate), scum scraping device, slag hopper (including slag discharge pipe), water outlet tank (non-concrete), electric control box, track and its accessories (non-rubber wheel) and all embedded parts shall be ordered separately.

3. The materials include underwater stainless steel (304 steel), working bridge (aluminum alloy, stainless steel), walkway plate (stainless steel, glass fiber reinforced plastic), baffle plate and weir plate (stainless steel, glass fiber reinforced plastic) and steady flow tube (stainless steel, glass fiber reinforced plastic). The material or anti-corrosion requirements are not indicated, indicating that the order is made according to carbon steel and ordinary anti-corrosion.

4. Reducer (imported and domestic) has two types of shaft-mounted and horizontal cycloid to choose from. It is not specified that the horizontal domestic cycloid or planetary order is required.

5. The allowable torque value of all equipment corresponds to the rated power and rotating speed. Any function expansion needs to be ordered separately (such as the increase in the number of rake arms, automatic rake lifting, water cleaning brush, etc.).

6, different pool bottom slope, pool depth or other pool structure should be required, another request data, to discuss the order.
