The specific embodiment
See Fig. 3, the present invention includes lower end and be provided with the casing 1 of bracing frame; Described casing 1 is provided with water inlet 1-1, delivery port 1-2 and mud discharging mouth 1-3; The inner space of described casing 1 is separated into the first flocculating chamber 2, the second flocculating chamber 3, separation chamber 4 and mud collection area 5; Described the second flocculating chamber 3 is arranged on the outside of the first flocculating chamber 2, and separation chamber 4 and mud collection area 5 are arranged on the outside of the second flocculating chamber 3, and separation chamber 4 is arranged on the top of mud collection area 5; The top of described separation chamber 4 is provided with separating inclined plate district 6, and the top of separation chamber 4 is provided with the effluent weir 7 communicating with delivery port 1-2; The lower end of described the first flocculating chamber 2 is connected with a trunnion 8, and the upper end of trunnion 8 is connected with reflecting plate 9, and the lower end of trunnion 8 is provided with flaring atrium 10, is provided with nozzle 11 under atrium 10, and nozzle 11 is fixedly installed on water inlet 1-1; The delivery port 1-2 place of described casing 1 inside is provided with online effluent quality analyzer 12; The top of described casing 1 is provided with self-checking device 13; Described self-checking device 13 comprises support 13-1, screw rod 13-2, transmission mechanism and reductor 13-3; Described support 13-1 is fixed on the top of casing 1; Described screw rod 13-2 is in transmission connection by transmission mechanism and reductor 13-3 and is erected on support 13-1; The lower end of described screw rod 13-2 is connected with the top of the first flocculating chamber 2; Described reductor 13-3 is meticulous helical speed reduction gear.
Operation principle of the present invention is: the mixed liquor that adds medicament is added in casing by water inlet, injection by nozzle 11 forms negative pressuren zone, body refuse mixes with mixed liquor because this negative pressure is inhaled into and enters the first flocculating chamber 2 from trunnion 8, form and reflux, this process implementation the quick contact of medicine, water, body refuse, enter behind the first flocculating chamber 2, several materials are swift in response and form good flocculation.Entering into behind the second flocculating chamber 3, because the cross-section of river along journey increases gradually, thereby flow velocity reduces gradually, is conducive to growing up of flocculation, is beneficial to precipitation.Current enter behind separation chamber 4 by reflecting plate 9, because flow velocity greatly declines, body refuse separates with water under Action of Gravity Field, the arranging of reflecting plate 9 changed the flow direction of flocculation mixed liquor, make current be loudspeaker diffusion type and flow, take full advantage of pond and hold, runner face expands, reduced the disturbance of bottom mud layer, solid-liquid separation effect promotes.The body refuse of separating, major part is returned bottom recirculation with the power of water-jet, and fraction is discharged by mud discharging mouth 1-3.Rise and enter separating inclined plate district 6 with the mud of little flco, separating inclined plate district 6 provides little flco to collide in conjunction with carrier side, strengthen little flco in conjunction with becoming large chance, further carry out effective separation of solid-liquid, the water after clarification has delivery port 1-2 to discharge by effluent weir 7.
In this design, nozzle 11 is part and parcels, the diversification of forms of nozzle 11.According to experiment and practical application, develop be applied to this equipment have cylindrical nozzle, conical nozzle, spiral nozzle, a fan nozzle, can select according to different water quality, water yield situation, therefore, for guaranteeing that optimum flow condition obtains optimum outlet effect, nozzle 11 installation forms of automatic adjusting water-jet clarifier have been carried out to a large amount of practice and used, determined firm sleeve type detachable form, this connected mode is solid and reliable, be beneficial to and safeguard and change.
Different water quality, water conservancy conditions need different sludge backflow amounts, and in actual moving process, water quality, water conservancy condition often fluctuate larger, if sludge backflow amount cannot be adjusted, will affect the water quality situation of water outlet.And the adjusting of sludge backflow amount is by regulating nozzle 11 and the spacing of trunnion 8 to realize, therefore, how quantitative spacing determines that the best backflow water yield becomes the key of research and development.For avoiding the loaded down with trivial details of manual adjustment, improve automaticity, this device is provided with self-checking device 13 and regulates the spacing of nozzle 11 and trunnion 8, self-checking device 13 regulates scale by the rotation spacing that meticulous helical speed reduction gear is set, in conjunction with online effluent quality determinator 12, the curve map of formation adjusting scale and effluent quality real time record are in automatic control system, thereby upper at scale, within the scope of lower limit, obtain the calibration points of best water outlet, this calibration points has directly been reacted the concrete amount of nozzle 11 with the spacing of trunnion 8, regulate thereby realize automatically, the best of having brought into play equipment is used ability.
Take up an area for strengthening clarifying treatment effect and saving, this equipment divides and is provided with separating inclined plate district 6 on the top of separation chamber 4, and small suspension, colloidal solid will further be assembled at this, collision, form large particulate matter, sink, solid-liquid separation effect improves greatly.The establishment in separating inclined plate district 6, surface loading is improved more than 1 times, in the equal situation of processing the water yield, floor space is greatly saved, solid-liquid contact area increases greatly, and separating effect obviously improves, and effluent index improves, it is 10mg/l that other clarifier water outlet can reach SS, and this device can reach below 5mg/l.
Consider equipment conveying, meet the condition of assembling, the structural member of the first flocculating chamber 2 of this equipment can overall Assembling, carries out on-the-spot bulk-breaking assembling by traveling nut, convenient and practical.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
