China DLB Style Gravity Valveless Filter Tank
■ Introduction
At present, there are two series of valveless filters produced by our factory: one is the square CBL-II filter, and the other is the round DLB-II filter. CBL-II, DLB-II series valveless filters do not use valves for water inlet, outlet, flushing and drainage, and operate automatically by hydraulic action, low operating cost, convenient management, safe and reliable, automatic operation, integrated equipment, water inlet The tank, filter, and backwash water tank are assembled into one, with a compact structure. Users only need to make the equipment foundation and connect the inlet and outlet water pipes as required to put it into operation. At the same time, the filter series products are equipped with a top cover, and the sanitary protection conditions are good. It can be set up in the open air, has a small weight compared with the reinforced concrete filter, and adopts a flexible foundation of asphalt sand.
■ Application
Gravity valveless filters are widely used in surface water purification, groundwater removal of iron and erbium, circulating water side-stream filtration, production wastewater removal of suspended impurities, subsequent filtration of organic sewage after biochemical treatment and secondary sedimentation tank treatment, and indoor swimming pool water The filtration is an ideal water treatment equipment.

Main Features
1. The inlet and outlet troughs around the sedimentation tank are designed with side-sections to ensure uniform water distribution and outflow around the sedimentation tank.
2. The driving device adopts a combination of a helical gear reducer and a worm gear reducer to ensure the output torque and speed, and the transmission effect is high; the reducer is equipped with an excessive torque protection device, which is safe and reliable in operation.
3. When φ≤40m, a single-sided straw is used, and if φ>40m, a double-sided straw is used.
4. The sludge suction pipe uses a horizontal perforated pipe to discharge the sludge, which does not interfere with the density flow in the tank and ensures the stability of the water.
5. sludge suction on the cone-shaped sludge suction pipe is uniquely designed and adopts variable hole pitch, from inside to outside, from small to large, to ensure balanced sludge suction at the bottom of the whole pond, increase sludge suction concentration, and save sludge backflow power.
6. There are two ways of skimming: plate skimming and tube skimming (the former is conventionally used).
7. The equipment is easy to operate, and the operation of the equipment can be directly controlled locally/remotely.
