Description

A kind of follow-on sludge vacuum dewatering unit
Technical field
The utility model relates to sludge treatment device field, is more particularly a kind of follow-on sludge vacuum dewatering unit.
Background technology
Because the water content of mud is very large, processed must be carried out to it before harmless treatment is carried out to mud, and sludge dewatering is that the mud that is primary, concentrated or digestion of fluidised form is carried out effective elimination moisture, make it a kind of method for sludge treatment being converted into semi-solid state or solid-state clod.Mud after dehydration, its water ratio can be reduced between eight ten 50 five to percent percent, depending on mud and the character of sediment and the usefulness of dehydration equipment.The dewatering of mud mainly comprises: natural mummification method, mechanical dehydration method and comminution granulation, and wherein natural mummification method and mechanical dehydration method are applicable to sewage sludge, and granulation rule is applicable to the mud of coagulating sedimentation.Mechanical dehydration method comprises filtration method and centrifuging, and filtration method is filtered by wet mud filtering layer (porous material is as filter cloth, wire cloth), and make moisture (filtrate) infiltrate filtering layer, dewatered sludge (filter cake) is then trapped within filtering layer; Centrifuging borrows the different tendency to drift aways that in mud, solid, liquid difference in specific gravity produces to reach mud-water separation.The equipment of filtration method has vacuum filter, plate-and-frame filter press and band filter.Vacuum filter enters mud continuously, and continuous mud extraction, operates steadily, but affiliated facility is more; Plate-and-frame filter press is chemical industry common equipment, and filtered driving force is large, and moisture content of the cake is lower, and enter mud, mud extraction is interval, productivity is lower, and manually-operated plate-and-frame filter press, labour intensity is very large, mostly uses machine automatization operation instead; Band filter is novel filter, has multiple design, and the dewatering Principle of foundation also has difference (gravity filtration, filtering under pressure, capillary suction, granulation), but they have rotating belt, transport mud, while dehydration, or only have the effect of fortune mud, their complicacy and energy consumption are all close.Mechanical dehydration method is mainly used in primary sedimentation pond mud and digested sludge, the water ratio of its dewatered sludge is relevant with sludge quality and dewatering, generally, the moisture content of the cake of vacuum filtration is eight ten ten to percent 6 percent, filter press is eight ten 40 five to percent percent, and centrifuge dehydration is eight ten five ten to percent 8 percent.
In order to make the efficiency of vacuum filtering and dewatering higher, the staff of this area have devised multiple sludge vacuum dewatering unit, as Chinese patent application publication No. sludge vacuum subcharge combined compressing and dewatering device disclosed in CN 101759342 A, this equipment has the effect of thickened sludge, negative pressure of vacuum and the pressure that provides of preloading device that vacuum pump formed are provided, mud under geomembrane is compressed, the moisture in mud is made to enter the discharge pipe line in compression pond by filtering layer, and introduce in sewage surge tank, complete the operation process of sludge dewatering.But the structure that the filtration of this sludge dehydration device filters with mode and traditional muddy water is identical with method, all by arranging filtering layer bottom it, then moisture filter is carried out, this structure not only needs the filtration facility laying multilayer, complex structure, with high costs, and its filter effect neither clearly, dehydration rate is not very high; On the other hand, the limitation of this dewatering and filtering structure is very large, can not be used in different sludge treatment places neatly.

Further, the sidewall of described sewage permeation joint is laid with several infiltration pores, and also pads between this sewage permeation joint and pipe connecting and be provided with a sealing annular collar.
Further, described water-level control apparatus comprises two and is arranged in series, for controlling the first float switch and second float switch of the unlatching of this water pump or closedown, this first float switch is located at the bottom of described sewage surge tank, and this second float switch is located at the top of described sewage surge tank.
Further, the height that described limit switch is arranged is positioned at the top of this second float switch.
Further, described water pump is also equipped with a water check valve.
Further, described valve tube is also equiped with one for measuring the pressure-measuring device of vacuum magnitude.
Further, the bottom of described sewage surge tank is also provided with one to rinse this sewage surge tank water port for blowdown.
By above-mentioned known to description of the present utility model, compared to the prior art, the utility model has the advantage of:
