Description

Sewage comprehensive purifying device

The utility model relates to a kind of waste disposal plant, particularly the matching used waste disposal plant of vehicle cleaning equipment.

At present, the integral water purifying device that occurs has several both at home and abroad, " a kind of continuous operation water treatment refining plant " as Chinese patent mandate that CN2160657Y announces, its primary structure principle is as follows, the source water that is added flocculation agent by the source water pump sprays into coacervation chamber, first Room by the water inlet pipe nozzle, in this chamber, set up the spiral stream guidance device, thus current are rotated rapidly and on, accelerate coacervation.Set up inner bag in hopper dredger, the active sludge of inner bag is because the suction function at nozzle place enters the coacervation chamber simultaneously.Like this, source water, flocculation agent and active sludge just enter in the coacervation chamber, first Room and the second Room reaction chamber and mix fully and react, and form alumen ustum, quicken air supporting.In the second reaction chamber exit, primary water separates with body refuse, and small-particle alumen ustum and air supporting thing are dammed by sloping plate unit in uphill process and precipitate, and primary water rising process filtering layer district and filtering head are behind overflow groove, and water outlet is then as clear as crystal.Suspended substance is lower than 4mg/L, the superstate drinking water standard.Mud that is overflowed by inner bag and the mud in the hopper dredger rise up into the siphon bucket by siphon pipe by suction function, enter the storage mud box by the siphon comb, form the treatment process of operation continuously.As general purifier, it has itself characteristics and distinctive feature, but as the treating plant that cleans the vehicle cycling use of water, and complex structure and having involved great expense just seems, because of cleaning the vehicle water is undrinkable water, as long as suspension content is lower than 4mg/L and promptly satisfies service requirements.

The purpose of this utility model is the demand that must save Freshwater resources, employing recirculated water at China's carwash industry, mainly constitute these characteristics of pollution in conjunction with automatic car washing machine plumbing amount and carwash sewage, design a kind of decontamination effect improving sewage comprehensive purifying device better, simple in structure by dust.

For achieving the above object, the utility model adopts following technical scheme: water inlet pipe (10) be arranged on housing bottom nozzle (13) vertically upward and be communicated with, housing bottom is hopper dredger (14), (15), top over against nozzle (13) is first reaction chamber (6) of inverted cone shape, its periphery is second reaction chamber (5) of tubular, the periphery of second reaction chamber (5) is the inclined tube separate chamber (8) of tubular, the periphery of inclined tube separate chamber (8) is filter chamber (9), filter chamber (9) lower end picks out water pipe (11), hopper dredger (15) bottom connects siphon shore pipe (2), the end opening of first reaction chamber (6) docks with trunnion (12), the sewage ingress of trunnion (12) is horn-like, a umbrella cover of the external stability of trunnion (12) (3), blank pipe (1) runs at siphon shore pipe (2) lowest water level place, the filtering layer upper edge is connected to recoil effluent outfall (4) in the filter chamber (9), and second reaction chamber (5) is gone up the top and established upflow tube (7).

By such scheme as seen, be connected to trunnion (12) in first reaction chamber (6) lower end, the lower end of trunnion (12) is a hydraucone, this structure makes the sewage of nozzle (13) ejection more effectively carry out coagulating with body refuse, the setting of umbrella cover (3) makes the settled part wadding of second reaction chamber (5) mud in umbrella cover (3) sinks to hopper dredger (14), has improved the coagulation effect that recycles; Because the dust content of carwash sewage is higher, be provided with evacuated tube (1) for the inner usefulness of thorough washing unit, also be provided with upflow tube (7) and recoil waste pipe (4), easy to use when filter chamber (9) stops up.

Fig. 1 is the structure principle chart of the utility model embodiment, be described further below in conjunction with embodiment and Fig. 1: integral body is a garden column-shaped barrel, nozzle (13) is positioned at the bottom of cylindrical shell, be to make the water level of high potential be converted into the device of high speed kinetic energy, the medullary ray of nozzle (13), trunnion (12) and first reaction chamber (6) overlaps fully, trunnion (12) is 10.2 with the ratio of nozzle (13) sectional area, both gaps are 30mm, hopper dredger (14) back cut diameter is identical with second reaction chamber (5) external diameter, and umbrella cover (3) lower end external diameter is less than the internal diameter suitable for reading of mud logical sequence (14).Sewage is several times as much as the activity circulation body refuse of flooding quantity around sucking after slush pump causes vacuum by nozzle (13) high-speed jet, in trunnion (12), carry out instantaneous mixing after, enter first reaction chamber (6) with certain speed.The speed of mixed flow reduces in first reaction chamber (6) gradually, cause the flow condition of certain speed gradient and certain duration of contact, to facilitate the formation of wadding grain, the mixed flow of cohesion is along with lift velocity slows down gradually, enter second reaction chamber (5) by the top and continue cohesion downwards, reaction, colloidal solid also increases gradually, in second reaction chamber (5) exit, lower end, primary water separates with the part body refuse, current enter inclined tube separate chamber (8) with certain speed and flow from bottom to top, the particle that part is not fully flocculated is failed settlement separate and is entered the inclined tube district with ascending current, after inclined tube dams removal, clear water continues to rise, after reaching a certain height, gully-hole enters and is positioned at outermost filter chamber (9) around the edge, and current after quartz sand layer filters, are discharged inflow clear water water reservoir by rising pipe (11) from top to bottom; Sink to hopper dredger (14) for recycling by the active wadding of the settled part of second reaction chamber (5) mud through umbrella cover (3); The wadding mud major part of being held back by inclined tube falls in the hopper dredger (15), after being stacked into certain altitude, discharges after siphon shore pipe (2) is opened valve; When needing thorough clean container inner, can open evacuated tube (1), sewage is all discharged thus; At the equipment normal operation period, when upflow tube (7) has the spilling water phenomenon, generally be that the quartz sand filtering layer stops up, need carry out the recoil of filtering layer high pressure, it is good clear water occurring with recoil effluent outfall (4).Inclined tube adopts polyvinyl chloride thin plate (0.4mm) moulding, inscribe garden diameter 35mm, and long 1M, along 60 ° of cylindrical shell helix angles, it holds back speed U _s=0.25mm/s.Ascent rate is trapped greater than the suspended particle of 0.25mm/s, sinks in the hopper dredger (15), ascent rate enters filter chamber (9) together with clear water by the gully-hole on inclined tube top less than the suspended particle of 0.25mm/s and filters into clear water.
