Sludge silo

Short Description:

Sludge silo used to store dewatered sludge, the silo body is made of carbon steel anticorrosion material, It facilitates the short-term storage of sludge as well as its outward transport, the equipment is in a good sealing ability, the bottom is fitted with a sliding frame, moving reciprocally under the drive of the hydraulic station to prevent sludge bridging. The screw at the bottom can control the quantity of the material, and the size and configuration of the silo can be customized according to customer requirements.

What is a sliding frame outloading System?
A sliding frame is an extremely efficient extraction system that allows non-free flowing materials to be discharged from a flat bottom silo or receival bunker. These bulk materials can easily block the bottom of a silo by forming a bridge of material. The action of the hydraulically driven sliding frame breaks any bridges that may form over the extraction screw and pushes/pulls the material toward the centre of the silo for discharge.

Rectangular silos–the sliding frame is constructed as a rectangular “ladder” shape, transferring material from one wedge shaped “step” of the “ladder” to the next as it oscillates back and forth.

The Sliding Frame is driven by a hydraulic system that makes the frame reciprocate slowly across the silo flat floor. As it does so, it digs the material from storage and at the same time delivers it into a screw or screws situated beneath the silo floor. The screw or screws are thus maintained completely full and are therefore able to meter the material at the desired rate into the process.

Sliding Frame Silos are designed to function with non-free flowing and difficult materials such as de-watered sludge cakes and biomass materials. The flat silo floor concept gives many advantages such as the maximum possible sized discharge openings. The sliding frame discharger creates “mass flow” within the silo even with these difficult materials. The client can be sure of achieving accurate discharge and metering of the stored material on demand no matter what the application.
