Background technology
Mud is the inevitable outcome after sewage treatment plant and sewage plant sewage disposal, after processing the mud entrance environment disposed very well, it will bringing secondary pollution directly to water body and air, the activity to ecological environment and the mankind also will constitute serious threat.Therefore, Treatment of Sludge is the most prudent.Sewage can produce a large amount of mud after precipitation process, even across concentrating and digestion process, and moisture content still up to 96%, sufficiently bulky, it is difficult to disposals of dissolving, it is necessary to through processed, the solid content of raising mud cake, to reduce the floor space that mud is banked up.
Traditional sludge dehydration device volume ratio is relatively big, as higher in centrifugal dehydrator rotary speed, and noise is big, and conventional dehydration device dehydrated structure is single, inefficient.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of stagewise sludge dewatering equipment, solves the problem that prior art dehydration device dehydrated structure is single, inefficient.
A kind of stagewise sludge dewatering equipment, including frame, drive motor, dehydration device, filtrate retracting device, described filtrate retracting device is arranged on the lower end of dehydration device, described dehydration device is inclined in frame, described dehydration device bottom is provided with mud inlet, top end is provided with mud mouth, the top of dehydration device is located at by described driving motor, described dehydration device includes dewatering cavity, helical axis, screen cloth, described dewatering cavity is a hollow circular cylinder, described dewatering cavity includes determining ring and rotating ring, described determine that ring and dewatering cavity cavity wall are fixing to be connected, described determine ring and described rotating ring is layered on top of each other.Described dewatering cavity is divided into four sections, and rotating ring both sides are determined the gap width in gap between ring be sequentially reduced to mud mouth direction along mud inlet with adjacent, and described helical axis is connected with driving motor, extends vertically into the bottom to dewatering cavity；Described screen cloth Matching installation is in the outside of folded breechblock, and described screen cloth includes that screen frame and grating, described grating are disposed in an evenly spaced relation on screen frame.
This utility model further improvement project is, the gap width of described four sections of dewatering cavities is 0.5mm, 0.4mm, 0.3mm, 0.2mm, and wherein the gap width of every section is identical.
This utility model further improvement project is that the pitch of described helical axis is sequentially reduced along mud inlet to mud mouth direction, is configured pitch according to equal difference, and pitch is 180mm, 190mm, 200mm, 210mm.
This utility model further improvement project is, the lead angle of described helical axis is more than or equal to 20 °.
This utility model further improvement project is, described filtrate retracting device is filtrate accumulator tank, and the bottom of filtrate accumulator tank is provided with filtrate outlet.
This utility model compared with prior art, has the advantage that
1, described dewatering cavity is divided into four sections, rotating ring both sides are determined the gap width in gap between ring be sequentially reduced to mud mouth direction along mud inlet with adjacent, this four segment structures, ensure that at first two sections, mud is fully concentrated, separates a part of filtrate, reduce sludge volume, rear two sections of dehydrations further to mud, improve dewatering efficiency and the dehydration rate of mud of entirety；
2, mud is rotated by helical axis in dehydration device and is compressed, and the moisture in mud is extruded out, and driven torus and the gap determined between ring are flowed out；Avoiding gap to be blocked by mud, screen cloth simultaneously arranges and mud can be made to be difficult to from screen cloth spill, it is to avoid sludge blockage mesh；
3, rotating ring is ceaselessly moving, and constantly clears up rotating ring and the dirt determined between ring between gap；Filtrate is reclaimed by filtrate retracting device, makees next step process；If if described lead angle is the least, squeezing effect can decline, and does not reaches required function.
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
