Description
Technical field
The present invention relates to washed-out sand sewage treatment equipment field, refer specifically to a kind of washed-out sand waste water solid segregation apparatus.
Background technology
Sandstone aggregate, as concrete primary raw material, plays skeleton and supporting role between floors, has indispensable status in nation-building. But sandstone aggregate needs the flushing that adds water in process of production so that it is clay content, wrap up in powder degree and meet the requirement of concrete production. 1 ton of finished sand building stones of general production need water consumption 1.5 cubic metres, and this process will produce a large amount of high-turbidity water. If untreated direct discharge, environmental pollution certainly will be caused, cause channel filling, water resource serious waste.
Washing the maximum feature of husky waste water is that silt content is high, and usual mass concentration is 6%-12%, even up to 20% time maximum. And in washed-out sand process, the earth that sandstone is mingled with very easily argillization on stream, become the shale that granularity is superfine, be suspended in washed-out sand waste water. It is big that high concentration, high shale content content result in washed-out sand wastewater treatment difficulty, shows themselves in that natural subsidence is slow, and flocculate pharmacy effect weak effect, and overflow turbidity is high, and underflow density is low. And owing to shale viscosity is relatively big, after the sedimentation of part washed-out sand waste water, the phenomenon that hardens occurs.
Usual washed-out sand Waste water concentrating processes and adopts sludge concentrator, is directly driven by motor reducer, does not set rake lifting device, and plant machinery structure is relatively simple, and harrow frame intensity is relatively low. When processing the washed-out sand waste water that above-mentioned mass concentration is high, silt content is high, argillization seriously, easily hardens, there arises a problem that single motor reducer directly drives, mud layer resistance is big, driving force is not enough, there is no Ti Pa mechanism, cause the long-time heavy service of driving mechanism, it is easy to damage reductor; Dispensing in distribution well, waste water is abundant not with flocculation pharmacy effect, and flocculation reagent consumption amount is high, and action effect is not good, easily goes out muddy water; Harrow frame intensity is relatively low, in high-drag mud layer, it is easy to be screwed bad.
Therefore, research and develop a kind of simple in construction, operation is convenient, be connected compact washed-out sand waste water solid segregation apparatus seems very necessary.
Summary of the invention

Further, the tangent plane of overflow spoiler is 30-60 �� with the angle of horizontal plane, it is preferred to 45 ��. So, easy for installation, retain the fine particle overflowed with current effective.
Further, the outfan of adjuvant adding tube is provided with first point of port, second point of port and the 3rd point of port, and first point of port is connected with the adjuvant import of pan feeding well, and second point of port and the 3rd point of port pass in feeding pipe. So, washed-out sand waste water is sufficiently mixed with flocculation medicament and has an effect.
Further, crane span structure is welded on cell body.
Yet further, cell body end face opening, side are the face of cylinder, bottom surface is the rounding conical surface. As such, it is possible to meet mechanical dredge, sedimentation effect is good, and wastewater treatment capacity is big, stirs little to water body, is conducive to suspended substance removal.
Yet further, scrape acquisition means and include center superposition and vertically arranged two truss. This way it is ensured that scrape the intensity of acquisition means, it is adaptable to the silt particle scrape collection high concentration, easily hardening, in using, do not have the problems such as deformation.
Advantages of the present invention is mainly reflected in following several respects:
One, present configuration is simple, operation is convenient, be connected compact;
They are two years old, washed-out sand waste water of the present invention is entered by feeding pipe, flocculation medicament is added on by adjuvant adding tube multiple spot in feeding pipe and pan feeding well, and washed-out sand waste water is sufficiently mixed with flocculation medicament and has an effect, so, silt particle in washed-out sand waste water flocculates agglomerating under the effect of flocculation medicament, then entered cell body by pan feeding well, then floc sedimentation settles downwards, scrapes collection finally by scraping acquisition means, discharged by discharge gate, clear water to overflow to downflow weir after discharge;
Its three, the present invention scrapes acquisition means and is designed as truss structure, and this design ensure that the intensity scraping acquisition means, it is adaptable to scrapes collection high concentration, the silt particle that easily hardens, does not have the problems such as deformation in using;
They are four years old, the present invention is when scraping mud resistance and being bigger, lifting device can pass through main shaft will scrape acquisition means lifting, prevent the long-time heavy duty work of driving device, scraping in acquisition means decline process, hydraulic means can also provide power, this power with under the dual function scraping acquisition means self gravitation, scrape acquisition means to be easier to decline, it is possible to solve the factors such as big, the mud layer hardening of mud layer viscosity and hinder the problem that acquisition means declines of scraping;
They are five years old, the overflow spoiler that the present invention arranges along downflow weir for one week, it is possible to prevent the subparticle shale by scraping the stirring of acquisition means end to rout up entrance downflow weir directly up, this shale granule is in the process walking around overflow spoiler, can settle down on overflow spoiler, downflow weir will not be directly entered, it is ensured that the quality of overflow water;
They are six years old, equipment is run and carries out real-time intelligent monitoring and control by PLC intelligent controlling device of the present invention, according to the parameters such as mud layer resistance, overflow water quality, underflow density, real-time automatic adjustment equipment running status, manual operation equipment can be substituted completely, stopped the damage that equipment is caused by maloperation.
