Abstract
This invention provides a novel, high-rate mud dewatering machine. It is composed of: several parallel arranged plates and the hydraulic compressing mechanism for pressing said plates. Some plates or all of the plates are equipped with compressing plates, hydraulic oil chambers. Between the plate and the compressing plate equipped is the filter cloth. During the compression, the plates are sealed. The dewatering machine also has a mud-conveyer and the filtrate drainage tube. The dewatering pressure is up to 3-5 MPa/cm2, being greater than that of plate frame filter, drum separator or band filter. The mud, after being dewatered, contains water content is lower than 45%. It can treat large amount of mud, suitable for treatment of mud from urban or industrial waste-water.
Description
Technical field
The present invention relates to the higher device for dehydrating sladge waste technical field of water content.
Background technology
Sewage disposal is the important content of environment protection, can produce the higher mud of a large amount of water ratio in sewage disposal.At present, these mud are attempted by flame filter press, rotary drum whizzer 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 water ratio is also quite high, fall into wheel during 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 sludge treatment has been become a problem demanding prompt solution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of mud of high-moisture percentage can being dewatered to the novel enhanced sludge dewatering machine than low-water-content.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 water extracter is provided with the hydraulic pressure hold-down mechanism that described some plates are compressed, be provided with rammer board in the part or all of plate, can be by the rammer board of oiling and oil extraction squeezing dynamicliquid pressure oil pocket, can be moved back plate dynamicliquid pressure oil pocket by the rammer board of oiling and oil extraction, described rammer board is in the face of adjacent plates, the adjacent plates surface that rammer board surface and rammer board are faced is respectively equipped with filter cloth, be sealed and matched around it when plate is compacted between plate, described water extracter is provided with mud and carries runner and filtrate flow pass.Owing to adopt technical scheme of the present invention, the present invention can adopt hydraulic ram to carry out the dehydration of rammer board sludge pressing as power and rammer board resets, 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 whizzer and belt filter press, moisture percentage in sewage sludge can be taken off to below 45%, and the sludge treatment turnout is big, can be applicable to the processing needs of city or industrial sewage mud.
