Flat flow type air-float pool for water treatment bottom automatic sludge discharger
Technical field
The utility model relates to flat flow type air-float pool for water treatment, relates in particular to a kind of flat flow type air-float pool for water treatment bottom automatic sludge discharger.
Background technology
In water treatment procedure, often need to use air supporting treatment process.Air supporting treatment process passes into air exactly in waste water, and from water, separate out and become carrier with micro-bubble form, the pollution substances such as the oil in water emulsion in waste water, small suspended particle are sticked on bubble, with bubble, float to the water surface, form foam one gas, water, particle (oil) three-phase mixture, the object that reaches separating impurity, purifies liquid waste by collecting foam or scum silica frost.By Bubble-floating Method is mainly used to process in waste water by natural subsidence or floating and is difficult to the oil in water emulsion removed or relative density close to 1 small suspended particle.
Flat flow type air-float pool is generally steel design, is main body and the core of sewage treating machine, and inside is comprised of reliever uniform device, sludge pipe, rising pipe, sludge sump, scraper plate and transmission system etc.Reliever is placed in air floatation machine middle position, is the key part of producing microbubble.The dissolved air water that dissolved air water device comes here fully mixes with waste water, and sudden outburst produces vigorous agitation and eddy current, form the microbubble that diameter is about 20-80um, thereby attach on the flocs unit in waste water, thereby reduce the proportion of flocs unit and rise, clear water is thoroughly separated.The tapered structure of uniform device, is connected on reliever, and Main Function is that clear water and the mud separated are dispersed evenly to Chi Tizhong.Rising pipe is distributed in body bottom, pond, and by a upright supervisor, is connected to body top, pond and overflows, and spillway is provided with regulation of level handle, is convenient to water level in regulating tank.Body top, pond is provided with sludge sump, has scraper plate on groove, and not stall of scraper plate is moving.Constantly the mud of floating is scraped in sludge sump, certainly flow in sludge sump.Sludge pipe is installed on pond body bottom, for discharging the throw out being deposited at the bottom of pond.
Discharge the throw out being deposited at the bottom of pond and need operate manually the valve on sludge pipe at every turn.Because conventional pond body is square flat, the in the situation that of long-time not spoil disposal, the situation that easily causes sludgd deposition cannot discharge in pond body bottom.Running into this situation just need be all emptying by the water of equipment downtime Chi Tizhong, at the bottom of personnel's lower storage reservoir, could clear up spoil disposal.Thereby have influence on the normal operation of equipment, inconvenient operation, wastes time and energy.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of flat flow type air-float pool for water treatment bottom automatic sludge discharger, can automatically discharge the throw out being deposited at the bottom of pond.
The utility model provides a kind of flat flow type air-float pool for water treatment bottom automatic sludge discharger to comprise flat flow type air-float pool, in the middle of the bottom of flat flow type air-float pool, be provided with collection mud groove, collection mud groove both sides by swash plate, be connected with the pond body sidewall of flat flow type air-float pool, swash plate bottom be connected with the top of type recess sidewall.Throw out in pond enters collection mud groove by pond body sidewall and swash plate.The inside axial direction due of collection mud groove is provided with transmission rod, and the surface of transmission rod is provided with spiral scraping blade, and one end of transmission rod is passed pond body sidewall and is connected with electric reducer, and the other end of transmission rod is fixed on the end of collection mud groove.Electric reducer drives transmission rod to rotate, and spiral scraping blade makes throw out be focused to the other end of collection mud groove.The below of collection mud groove is provided with the sludge hopper for collecting precipitation thing.
Described sludge hopper is positioned at the below of spiral scraping blade driven end, makes the collecting precipitation thing of sludge hopper maximizing.The bottom opening of sludge hopper is also connected with flange in turn and motorized valve, and motorized valve is extracted the throw out of collecting in sludge hopper out.
The axial direction due of described collection mud groove is consistent with water (flow) direction, is convenient to spiral scraping blade promotion throw out and enters sludge hopper.
Described electric reducer and motorized valve are provided with the time relay and the hand auto-switching push button that can carry out time control.
The utility model compared with prior art, adopts the time relay to control electric reducer and motorized valve, without artificial Open valve, only need set working time, can fully automatic operation.The utility model has hand automatic switching function simultaneously, easy to use.The utility model utilizes swash plate and collection mud groove collecting precipitation thing, by coordinating of each motor setting and transmission rod and spiral scraping blade, automatically collect and sediment exclusion, the problem that has solved the easy deposition in conventional flat flow type air-float pool bottom and be difficult to discharge, no longer need by pond body is emptying clear up pond at the bottom of, can not affect normal operation convenient, time saving and energy saving.

Embodiment
According to Figure of description and specific embodiment, the utility model is described in further detail below:
The utility model provides a kind of flat flow type air-float pool for water treatment bottom automatic sludge discharger, comprise flat flow type air-float pool 1, in the middle of the bottom of described flat flow type air-float pool 1, be provided with collection mud groove 2, collection mud groove 2 both sides are connected with the pond body sidewall of flat flow type air-float pool 1 by swash plate 3, the bottom of swash plate 3 is connected with the top of collection mud groove 2 sidewalls, the inside axial direction due of collection mud groove 2 is provided with transmission rod 4, the surface of transmission rod 4 is provided with spiral scraping blade 5, one end of transmission rod 4 is passed pond body sidewall and is connected with electric reducer 6, the other end of transmission rod 4 is fixed on the end of collection mud groove 2, the below of collection mud groove 2 is provided with sludge hopper 7.Sludge hopper 7 is positioned at the below of spiral scraping blade 5 driven end, and the bottom opening of sludge hopper 7 is also connected with flange 8 in turn and motorized valve 9.The axial direction due of described collection mud groove 2 is consistent with water (flow) direction.Electric reducer 6 and motorized valve 9 are provided with the time relay and the hand auto-switching push button that can carry out time control.
As shown in Figure 1, Figure 2 and Figure 3, in the present embodiment, the collection mud groove 2 that in pond, mud flows at the bottom of being arranged in pond along pond body sidewall and swash plate 3, after electric reducer 5 energisings, drive the spiral scraping blade 5 on transmission rod 4 to rotate, the mud of accumulation in collection mud groove 2 is transported in sludge hopper 7, then by pilot circuit, motorized valve 9 is opened, mud is discharged.
Further, under normal conditions, this utility model can change the length of transmission rod 4 and the quantity of spiral scraping blade 5 according to the length of different air flotation pools.Controlling System is simple, and only, to electric reducer 6 and motorized valve 9 power supplies, operator's setup times rly. carries out time control, utilizes hand auto-switching push button to carry out hand automatic switchover and uses.
