Decanters Sludge Dewatering Equipment

Consists of horizontal spiral sedimental centrifuge, dosing unit, into the mud pumps, dosing pumps, shaftless screw conveyors, flow meters, control valves and PLC control system.

1. the host machine:

LW series horizontal spiral sedimental centrifuge discharge is one of the main equipment of sludge dewatering system, mainly by the high speed rotating drum, drum steering screw of the same, and formed a certain rotational speed difference, differential and frame components. When after the sludge into the centrifuge Chamber, powerful centrifugal high-speed rotating drum, sludge particles due to density, centrifugal force caused by the large sludge sedimentation in the drum wall, forming a circular solid mud cake layer; while the density of water is small, centrifugal force is small, only formed a solid layer in liquid layer. Due to the screw and turn the drum at different speeds, there is relative motion between (the differential speed), through the spiral of sludge deposited on the inner wall of the drum into the drum front discharge outlet, isolated from the other end of the water from the drum discharge. Differential role is to form a certain rotational speed difference between drum and spiral. Sludge dosing coagulants, flocculation, brought together disperse sludge particles causing big flocs, speed up the mud-water separation.

2. Electrical control system:

On grinding cutting machine, feeding pump, flocculation agents with automatic/manual switching device, centrifuge operation, operation monitoring, fault alarm and interlock.

PLC automatic control system with constant torque automatically adjust the feed rate function; according to the loading torque, speed increases automatically in order to prevent the blocking feature; 11.3-inch color touch-screen operation, display the working parameters of machine.

Complete set of control systems in accordance with pre-determined procedures can be initiated on the centrifuge, separate, parking, cleaning and other control could also smash-cut to sludge, conveyors, flocculant side projection, dried mud, transportation and other conditions of automatic control.

Flocculant concentration of distribution switch device can be set according to the user automate flocculant preparation work.

3. LS shaftless screw conveyors mainly consists of driving device, shaftless spiral blade, u-shaped trough, replaceable wear-resistant lining, machine frame. Used mainly for exports dewatered sludge cake by centrifugation machine delivered to an outdoor mud field or transport vehicle, the entire work carried out in a closed state, keeping the environment clean.

4. Flocculant cast device

Third box-type polymer flocculants offers switching device is a highly efficient new macromolecular flocculant preparation device can continuously good preparation and preparation of flocculant dosing the liquid to mix into the centrifuges in sludge. Main components: automatic dry powder dosing equipment, automatic water dosing devices, mixing equipment and pipeline valves
