Sludge treatment, separation and filter-pressing device for sewage treatment plant and operation method of device

Abstract

The invention discloses a sludge treatment, separation and filter-pressing device for a sewage treatment plant. The device comprises a filter-pressing fixed driving mechanism, a filter-pressing platemechanism and a movable hook mechanism; the filter-pressing plate mechanism and the movable hook mechanism are both fixedly arranged on the filter-pressing fixed driving mechanism. Meanwhile, the invention further discloses an operation method of the sludge treatment, separation and filter-pressing device for the sewage treatment plant; when the movable hook mechanism pulls a filter plate body toone end of a supporting guide rail batten, and an arc-shaped curved bar passes through a height limiting column, the height limiting column presses the arc-shaped curved bar, so that a pressing columnpresses one end of a warping plate downwards, and the warping plate jacks up the other end of a pushing column; the pushing column pushes a first limiting lug to push up the filter plate body; afterthe arc-shaped curved bar moves over the height limiting column, a second reset spring is reset, the pushing column moves downwards, the filter plate body falls down, and the process is repeated, so that vibration of the filter plate body is realized, and mud cakes adhered to the surface of the filter plate body are vibrated to fall down.

Description

technical field [0001] The invention relates to the technical field of sludge treatment equipment, in particular to a sludge treatment separation filter press device for sewage treatment plants and an operating method thereof. Background technique [0002] Sludge treatment is the process of sludge reduction, stabilization and harmless treatment. The higher the degree of wastewater treatment, the more sludge residues are generated that need to be disposed of. For modern sewage treatment plants, the treatment and disposal of sludge has become the most complex and expensive part of the operation of the sewage treatment system. Sludge treatment: Concentrating, tempering, dehydrating, stabilizing, drying or incinerating sludge to reduce, stabilize and harmless the process. [0003] In the prior art, when sewage treatment plants treat sludge, most of them use filter press devices to separate water and mud. However, when the existing filter press devices perform filter press sepa...

Problems solved by technology

[0003] In the prior art, when sewage treatment plants treat sludge, most of them use filter press devices to separate water and mud. However, when the existing filter press devices perform filter press separation, the mud after filter press will form mud cakes. Attached to the filter plate, it is not easy to fall off, and it is not convenient to transport to the incineration site later, which brings inconvenience to the treatment process
