Description
Technical field
The present invention relates to higher mud dewatering method of water content and equipment technical field.
Technical field
Sewage disposal is the important content of environmental protection, can produce the higher mud of a large amount of moisture content in sewage disposal.At present, these mud are attempted by flame filter press, rotary drum centrifuge or belt filter press dehydration, but these three kinds of equipment are difficult to adopt higher squeeze pressure and centrifugal pressure, and the moisture percentage in sewage sludge after the dehydration is generally also 75%～80%.Mud majority after the dehydration transports the landfill yard landfill to, and the higher mud of small part calorific value adds in the coal and burns after drying or drying.Wherein transport the mud of landfill yard to, because moisture content is also quite high, fall into wheel during bull-dozer work, can't landfill operation, drying time is long, causes mosquitos and flies to grow and makes environmental pollution, many landfill yards are unwilling to receive, simultaneously landfill mud takies a large amount of soils, therefore, current Treatment of Sludge has been become a problem demanding prompt solution.
Summary of the invention
The present invention's technical problem at first to be solved provides a kind of mud of high-moisture percentage can being dewatered to the sludge pressing filter method than low-water-content.For this reason, the present invention is by the following technical solutions: it may further comprise the steps successively:
1), form that several are parallel and can be filled the space by the mud of interlock compression,
2), fill the space to mud and fill mud to be filtered,
3), adopt hydraulic coupling compression mud to fill the space, squeeze and filter mud,
4), open mud and fill the space, mud falls to removing.
Owing to adopt technical scheme of the present invention, the present invention can adopt hydraulic coupling as squeezing power, high efficiency, dewatering pressure can reach 3～5Mpa for every square centimeter, squeeze force has greatly improved squeezing efficient much larger than flame filter press, rotary drum centrifuge and belt filter press, moisture percentage in sewage sludge can be taken off to below 45%, and the Treatment of Sludge output is big, can be applicable to the processing needs of city sewage and sludge.
Another technical problem to be solved of the present invention provides a kind of enhanced sludge dewatering machine of application said method simple in structure.For this reason, the present invention is by the following technical solutions: it comprises the plate that several are arranged in parallel and can relatively move before and after the orientation, described dewaterer at one end is provided with the hydraulic means that drives plate, and described plate comprises the rammer board with concave surface of adjacent arrangement and has the rammer board of convex surface; One of them face is coated with filter cloth in concave surface of facing mutually and the convex surface, described dewaterer is provided with when the rammer board with concave surface and rammer board with convex surface insert to cooperate the seal in space between two plates, and described dewaterer is provided with the filtrate flow pass that communicates with concave surface that is coated with filter cloth and convex surface.Owing to adopt technical scheme of the present invention, the present invention is simple in structure, can only compress with realizing that once the cover hydraulic means mud fills the formation in space and mud is filled the space, high efficiency, dewatering pressure can reach 3～5Mpa for every square centimeter, squeeze force is much larger than flame filter press, rotary drum centrifuge and belt filter press, greatly improved squeezing efficient, moisture percentage in sewage sludge can be taken off to below 45%, and the Treatment of Sludge output is big, can be applicable to the processing needs of city sewage and sludge.
