Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention discloses a sludge advanced dehydration treatment device and its treatment method, such as figure 1 As shown, it includes a screw conveying and extrusion integrated machine 1 and an extrusion dehydration chamber 2, the screw conveying and extrusion integrated machine 1 is connected to the extrusion dehydration chamber 2, and the screw conveying and extrusion integrated machine 1 includes a conveying shell 12 and The screw shaft 11 with variable pitch, the purpose of setting the screw shaft 11 at a variable pitch is to discharge the air in the sludge, so that the sludge entering the extrusion dehydration chamber 2 can generate sufficient extrusion force.

[0029] The extrusion dehydration chamber 2 includes a left filter plate 21 , a right filter plate 22 and a middle filter plate 23 , and the left filter plate 21 a...

Abstract

The invention discloses a deep sludge dehydration treatment device and a treatment method thereof. The deep sludge dehydration treatment device comprises a screw conveying and extrusion integral machine and an extrusion dehydration chamber, wherein the screw conveying and extrusion integral machine comprises a conveying shell and a screw shaft of a varying pitch; the extrusion dehydration chamber comprises a left filtering plate, a right filtering plate and a middle filtering plate; the left filtering plate and the right filtering plate are opened outwards or closed inwards by taking the middle filtering plate as a shaft. By adopting the deep sludge dehydration treatment device, the problems that in the prior art sludge is high in water content after being treated and the operation cost is high can be solved.

Description

technical field [0001] The invention relates to the field of sludge concentration and dehydration and drying, in particular to a sludge deep dehydration treatment device and a treatment method thereof. Background technique [0002] At present, in the process of sewage treatment, a by-product——sludge will be produced. Sludge is a solid sediment produced by water and sewage treatment. Sludge dehydration is to concentrate or digest sludge to remove water and convert it into A sludge treatment method of semi-solid or solid sludge. Energy conservation and emission reduction is one of the basic national policies for the sustainable development of my country's economy. With the strengthening of water environment governance and protection, the treatment technology of sludge dewatering is also developing continuously. [0003] The existing urban domestic sludge or sludge concentration and dehydration equipment for farms and septic tanks generally include plate and frame filters, sta...
