Moreover, the invention can greatly save the transportation expenses of the sludge, and the economic efficiency is extremely obvious.
Description
Technical field
The present invention designs technical field of sewage, relates in particular to the dehydration equipment to mud in the sewage.
Background technology
Sewage disposal is the important content of environmental protection, can produce a large amount of mud in sewage disposal.At present, mud is by rotary drum centrifuge or belt filter press dehydration, and these two kinds of equipment are difficult to adopt higher squeeze pressure and centrifugal pressure, and filter efficiency is not high, and the moisture percentage in sewage sludge after the dehydration is generally also 75%～80%.Mud great majority after the dehydration transport the landfill yard landfill to, and the higher mud of small part calorific value adds in the coal and burns after drying.Wherein transport the mud of landfill yard to,, fall into wheel during bull-dozer work because moisture content is also quite high, can't landfill operation, drying time is long, causes mosquitos and flies to grow and makes environmental pollution, therefore, many landfill yards are unwilling to receive, and Treatment of Sludge has been become a problem demanding prompt solution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of belt strong force squeezing dewatering machine that can reduce processing back moisture percentage in sewage sludge.For this reason, the present invention is by the following technical solutions: it comprises the foraminous conveyer that circulates up and down, described dewaterer comprises some groups of powerful pressure roller groups, and described powerful pressure roller group comprises pressure roller and bear the bearing roller of pressure roller pressure that the foraminous conveyer that circulates up and down passes between pressure roller and bearing roller; Described bearing roller is being provided with annular groove near place, its both sides, and described both sides of circulating foraminous conveyer up and down extend to described annular groove, and described dewaterer is provided with the device with the foraminous conveyer press-bending that circulates up and down at annular groove place that cooperates with annular groove.Owing to adopt technique scheme, the squeeze force of pressure roller can adopt the squeeze pressure of more common belt filter press to exceed many times high squeeze pressure in the powerful pressure roller group, greatly improve squeezing efficient, moisture percentage in sewage sludge after the processing reduces to 60%, can can be directly and carry out landfill easily by landfill yard, mummification again, and wherein the higher mud of calorific value need not dry yet can be directly and fuel mix use, avoided contaminated environment once more.And, after having reduced moisture content, can save the freight of mud significantly, economic benefit is fairly obvious.
