Sludge Treatment Equipment

Abstract

The invention relates to a sludge treatment equipment, comprising a shell, a treatment liquid feeding device and a sludge treatment system; the sludge treatment system is arranged in the shell; the treatment liquid feeding device passes through the shell After the body, it communicates with the inner cavity of the centrifuge cylinder of the sludge treatment system; the treatment liquid feeding device includes a treatment liquid interface, a pneumatic liquid inlet valve and a liquid inlet pipe; the pneumatic liquid inlet valve is connected to the treatment liquid Between the interface and the liquid inlet pipe; the liquid inlet pipe extends into the inner cavity of the centrifugal cylinder after passing through the housing; the pneumatic liquid inlet valve includes a valve body and a pneumatic liquid inlet plate arranged in the valve body and a push rod; the air pressure liquid inlet plate extends radially through the pipe body of the valve body; the pipe body communicates with the air pressure chamber of the air pressure liquid inlet plate. The pressure of the air pressure cavity in the air pressure liquid inlet plate is changed by the push rod to change the opening of the air pressure liquid inlet plate, which can precisely control the liquid intake, thereby avoiding the waste of processing liquid.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to sludge treatment equipment. Background technique [0002] Sludge treatment is a pollution-free process of thickening, conditioning, dehydrating, stabilizing, drying or incinerating sludge. [0003] In the prior art, the process of dehydrating sludge is generally carried out by centrifugal cylinder. During dehydration, treatment liquid is added to preliminarily treat the harmful substances in the sludge. However, the current centrifugal cylinder controls the amount of treatment liquid entering The valves are generally mechanical valves, and it is difficult to control the amount of treatment liquid. At the same time, the sediment in the treatment liquid is easy to accumulate in the mechanical valve, resulting in a reduction in the service life of the mechanical valve. [0004] The above-mentioned problems are urgently to be solved at present. Contents of the invention [0005] T...

Problems solved by technology

[0003] In the prior art, the process of dehydrating sludge is generally carried out by centrifugal cylinder. During dehydration, treatment liquid is added to preliminarily treat the harmful substances in the sludge. However, the current centrifugal cylinder controls the amount of treatment liquid entering The valves are generally mechanical valves, and it is difficult to control the inflow of the treatment liquid. At the same time, the sediment in the treatment liquid is easy to accumulate in the mechanical valve, resulting in a reduction in the service life of the mechanical valve.
