Abstract
The utility model discloses a sludge concentration tank which comprises a tank body, a speed reduction box, upper and lower layer mixing blades, a support frame, a sliding bearing, a flocculant dosing pump, a sewage lift pump, a sludge lift pump, an overflow port and a supernatant discharge outlet. The flocculant dosing pump and the sewage lift pump are connected on the upper end of the tank body through pipelines, the sludge lift pump is arranged at the lower portion of the tank body, and the tank body is provided with the overflow port and the supernatant discharge outlet. The sludge concentration tank has the advantages of being simple in manufacture, easy to operate, capable of combining links of flocculation and concentration and utilizing gravity of sludge for compression, good in precipitation and flocculation efficiency, short in sludge concentration time, suitable for activate sludge and floating sludge and mixed liquid of the activate sludge and the floating sludge, and strong in adaptability to water containing conditions of sewage.
Description
Technical field the utility model relates to sewage disposal device, relates to specifically a kind of sludge concentrating pot.
The background technology sludge concentrating pot is the key equipment of sewage disposal, and the moisture percentage in sewage sludge that produces in the sewage disposal is higher, becomes moisture less mud cake for contained mud in the sludge water is separated press filtration, must use sludge concentration device.
Summary of the invention is in order to overcome the shortcomings and deficiencies of the prior art part, and the utility model provides a kind of sludge concentrating pot, and is reasonable in design, improved the processing efficiency of sewage.
A kind of sludge concentrating pot comprises tank body, reducing motor, levels agitating vane, support and sliding surface bearing, flocculation agent dosing pump, sewage pump, sludge lifting pump, overflow port and supernatant liquor discharge outlet.Reducing motor is by the agitating vane in the dwang connection tank body, the dwang lower end is fixed on the support by bearing, flocculation agent dosing pump, sewage pump are connected to the upper end of tank body by pipeline, and the sludge lifting pump is arranged on the bottom of tank body, and overflow port, supernatant liquor discharge outlet are arranged on the tank body.
Described tank body diameter of section and effective liquid level are than being 1:3.
The radius of described agitating vane is 1 ∕ 3 of tank body radius.
The distance of described levels agitating vane is for filling with 4 ∕ 10 of height.
Described lower floor agitating vane is 1 ∕ 3 of effective liquid level at the height of distance tank base.
Described clear liquid discharging mouth is located at 4 ∕, 10 places of liquid level below.
The utility model has the advantage of: making is simple, and processing ease will flocculate and concentrate two links and merge, and utilize the compression of mud self gravitation, and the precipitation flocculating effect is good, and mud concentration time weak point only needs 30 minutes; Need not heat, energy consumption is low; Be adapted to active sludge and air supporting mud and mixed solution thereof, to the moisture situation strong adaptability of sewage;
Description of drawings Fig. 1 is structural representation of the present utility model.
A kind of sludge concentrating pot of embodiment comprises tank body 11, reducing motor 5, levels agitating vane 6,10, support 7 and sliding surface bearing 8, flocculation agent dosing pump 1, sewage pump 2, sludge lifting pump 9, overflow port 3 and supernatant liquor discharge outlet 4.Reducing motor 5 is by the levels agitating vane 6 in the dwang connection tank body, 10, the dwang lower end is fixed on the support 7 by sliding surface bearing 8, flocculation agent dosing pump 1, sewage pump 2 are connected to the upper end of tank body 11 by pipeline separately, sludge lifting pump 9 is arranged on the bottom of tank body 11, and overflow port 3, supernatant liquor discharge outlet 4 are arranged on the tank body 11.
Theoretical and the sedimentation experiment data according to sludge settling, the rotating speed of well-designed reducing motor 5 is 35 rev/mins, levels agitating vane 6,10 radiuses are got 1 ∕ 3 of tank body radius, the distance of levels agitating vane is 4 ∕ 10 of the height of filling body 11, lower floor's agitating vane 6,10 is 1 ∕ 3 of effective liquid level apart from the height of tank base, guarantees that sewage and flocculation agent are in tank body 11 interior effective mixing, avoid the too high group of will flocculating of rotating speed to smash, guarantee that simultaneously mechanical electric power power consumption is minimum.
According to sludge settling data and curves and sedimentation compression requirement, the diameter of section of well-designed tank body 11 is 1:3 with effective liquid level ratio, guarantees that enough hydrostaticpressures are compressed to the bottom sludge settling requirement that is fit to the pressure filter press filtration with the shortest time.
Carefully calculate 4 ∕, 10 places that supernatant liquor discharge outlet 4 are located at the liquid level below, to greatest extent supernatant liquor is discharged into equalizing tank and again processes, reduce the amount of sludge that needs through the pressure filter press filtration, improve the sludge press filtration effect, shorten time of filter pressing.
Sludge concentrating pot is the sludge water that produces in the sewage treatment process to be carried out flocculation concentration process, and reduces the sewage water ratio, satisfies the key equipment of sludge press filtration requirement design, and its working specification is as follows:
1, checks the fine status of concentration tank state and relevant device facility, close supernatant liquor discharge outlet valve and sludge lifting pump pump valve;
2, start sewage pump 2 lifting sewages and advance concentration tank, then start flocculation agent lift pump 1 by the flow that the regulates flocculation agent of annotating in the concentration tank;
3, when reaching upper strata agitating vane 6, the sewage water surface starts reducing motor 5;
4, when overflow port 3 beginning overflow sewage, stop sewage pump 2 and flocculation agent lift pump 1;
5, according to the sewage flocculation situation, stop reducing motor 5;
6, the static flocculation sediment of tank body 11 interior sewage is more clear to supernatant liquor, supernatant liquor discharge outlet 4 discharging be clear water the time, open the drain supernatant liquor on top of supernatant liquor discharge outlet valve;
7, start the sludge filter press system, then open the sludge lifting pump valve, startup sludge lifting pump 9 is all got to the sludge filter press press filtration with mud and is become mud cake; Finish an operation cycle process.
