Among the figure: 1 is that clear water zone, 2 is that inclined tube district, 3 is that Disengagement zone, 4 is that enrichment region, 5 is that last inclined tube, 7 is that declined board, 8 is the thickened sludge bucket for clarifying tank, 6.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
Like Fig. 1, a kind of high concentration mine tailing wastewater concentrating and precipitating device comprises clear water zone 1, inclined tube district 2, Disengagement zone 3 and enrichment region 4, and said clear water zone 1 is positioned at 2 tops, inclined tube district, and 2 belows, inclined tube district are enrichment region 4, and Disengagement zone 3 is between inclined tube district 2 and enrichment region 4.
Be provided with clarification tank 5 in the clear water zone 1.
Be provided with inclined tube 6 and declined board 7 in the inclined tube district 2.
The tilt angle alpha of thickened sludge bucket 8 is 60 degree.
Generally speaking, sewage all should add appropriate coagulant before getting in the sedimentation basin, so just can make suspension be condensed into big floccule body and accelerates subsidence velocity; And if in sewage, do not add coagulant, therefore the subsidence velocity of suspension will underspeed greatly, in order to improve the effluent quality effect; Just need corresponding raising effective depth; After having improved certain altitude, increase one deck inclined tube filler again, make that sedimentation effect is bound to be improved.
Sewage in the access arrangement is to be among the flow regime, if not have inclined tube filler, suspension be to flow along with the direction of current, so the speed of sedimentation mud is very low, and effect is very poor.Increased the hexagon cellular filler in the equipment, its one by one inclined hole will create a lot of metastable spaces to sludge settling, a lot of mud molecules will slowly glide along smooth tube wall; Make the downslide sludge blanket to get more and more; Density also can increase, and the speed that glides simultaneously also can improve, and makes whole settling zone form the dense more state of the darker sludge concentration of water layer; The speed that mud sinks also can be corresponding more and more faster, improved the sedimentation basin effect so greatly.Here it is, and the tube settler operation mechanism belongs to.Use this theory,,, just added one deck hexagon cellular filler in the decanting zone in order to improve sedimentation effect so, in sedimentation basin, do not add coagulant according to owner's requirement.So as to improving effect.
The wall thickness of the difference of swash plate and inclined tube: A, swash plate must be thickeied, and should use more than 3 millimeters, and should make reinforced support.Not only to increase big cost, and will increase difficulty of construction, prolong the installation cycle; The wall thickness of B, inclined tube is 0.45 millimeter, and bulk strength forms the hexagon shape of combining structure owing to be to bond together, and planar dimension is combined into 1 meter * 1 meter area can bear the above gravity of 150kgf/ ㎡, and swash plate can not.So inclined tube not only intensity is high, cost of manufacture reduces greatly, and construction period also is more than 1/5th of swash plate installation.Moreover, in running, swash plate is easy deformation also, and then there is not this problem in inclined tube.
High concentration mine tailing wastewater concentrating and precipitating device of the present invention adopts Combination Design.Be beneficial to flexible arrangement, rationally utilize the soil; Can make up according to the water yield during type selecting; More combinations.But the flexible design percentage reserve, it is convenient to open, stop, overhaul; There is not electromechanical equipment.Adopt the method for middle lower portion gravity flow suction type mud extraction, be difficult for stopping up, reliable.More more convenient than traditional radiation type precipitation pool and rectangular sedimentation tank mud extraction, and can save the concentration basin of establishing in addition, that the inclined tube material adopts is corrosion-resistant, wear-resistant, anti-aging, smooth surface, durable polypropylene material are processed.
