Abstract
The utility model relates to a horizontal type defoamer and belongs to the technical field of sewage treatment facilities. The defoamer comprises a flow guide tube which is mounted horizontally along the water flow direction, wherein a submersible motor which drives a forward-drainage impeller is mounted in the flow guide tube, the two sides of the flow guide tube are fixedly connected with two pontoons capable of countering weight, the pontoons can be subjected to re-counterweight by opening threaded sealing covers at ports of the pontoons, and connecting rings are welded to waists of the pontoons and are connected by chains so as to tow and locate. After the horizontal type defoamer disclosed by the utility model is started up, the horizontal flow velocity of a local tank surface of an aeration tank can be increased, and bubbles of dead corners are enabled to enter a cavity body of the flow guide tube along the horizontal direction, are smashed by the impeller and then rapidly leave original bubble areas, so that the problem that the bubbles of the dead corners of the aeration tank are easily stacked again is solved, and the operating environment of workers is improved.
Description
Technical field
The utility model relates to a kind of froth breaker, and especially a kind of horizontal type froth breaker belongs to the sewage treatment facility technical field, can be applicable to eliminate the foam that " dead angle " gathered in the sewage disposal plant aeration tank.
Background technology
Adopt in the Wastewater Treated by Activated Sludge Process sewage process, scum silica frost or frothing can periodically appear in the aeration tank, and be special particularly serious at " dead angles " such as the slower turning of relative velocity, turnings, and foam is long-pending very easily more thick more on the water surface, even corrupt smelly, the normal operation of puzzlement sewage work.
Eliminate the aeration tank foam at present, generally adopt the water sprinkling or add chemical defoamer, not only can cause a large amount of wastes, and can produce secondary pollution, do not meet the cleaner production requirement.Retrieval is found, application number is that 201110042628.4 Chinese patent discloses a kind of " pulsating is inhaled the foam machine ", be used for biological tank and eliminate mud scum, constitute by guide shell, floating drum, band impeller motor, under driven by motor, inhale the foam machine in the up-and-down movement process, will produce " shockwave " to its top and peripheral water body, guide shell and floating drum will produce effect of impact to the mud scum piece simultaneously, have certain elimination foamy effect.But this equipment is vertically installed, and does not have horizontal thrust, and for " dead angle " position of the relatively slow aeration tank of large-scale wastewater treatment plant surface velocity, the foam after the impeller fragmentation continues to gather if can not in time take away easily, and losing it should have effect.
The utility model content
In order to overcome the deficiency that prior art exists, the utility model proposes a kind of water saving, there is not secondary pollution, it is reliable to eliminate foam, can effectively prevent the horizontal type froth breaker that broken foam gathers again.
The technical scheme that its technical problem that solves the utility model adopts is: comprises guide shell, submersible machine, floating drum, described submersible machine is housed in described guide shell, and described submersible machine impeller high speed rotating, described guide shell and floating drum are connected; Described guide shell is along the horizontal installation of water (flow) direction.Described floating drum one end is equipped with thread sealed closure, but inside is the cavity of receiving fluids, can open described sealing cover described floating drum is carried out the water filling counterweight, guarantees that described guide shell water-in sub-fraction exposes liquid level.Described guide shell downwards forms 5 inclination angles about spending with liquid level toward water (flow) direction.Because of producing horizontal thrust forward behind the device start, described floating drum waist is welded with a shack, and described shack is located by chain traction.
As a kind of preferred version of the present utility model, described guide shell toward water (flow) direction downwards with the inclination angle of liquid level formation 2-10 degree.
As a kind of preferred version of the present utility model, described floating drum is carried out counterweight and reaches guide shell water-in no more than 1/2 exposing liquid level.
As a kind of preferred version of the present utility model, the water-in section area of described guide shell is greater than the section area of water port.
The utility model starts the back by driven by motor impeller high speed rotating, near the guide shell water-in, form certain negative pressure, surface, aeration tank " dead angle " foam is inhaled in the guide shell, shear and the centrifugal force extruding by the blade of impeller, after breaing up foam, release forward through leakage fluid dram, hightail former " dead angle " foam regions, prevent that foamy from gathering once more.
The beneficial effects of the utility model are: water saving, and non-secondary pollution, broken foam can hightail former foam regions, thoroughly eliminates the phenomenon that broken foam gathers once more, keeps the ideal foam to eliminate effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1 embodiment.
1. guide shells among the figure, 1-1. guide shell water-in, 1-2. guide shell water port, 2. submersible machine, 3. impeller, but 4. counterweight floating drum, 5. thread sealed closure, 6. shack, 7. chain.
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.
As shown in Figure 1, horizontal type froth breaker of the present utility model has the uncovered shape water-in of loudspeaker 1-1 and dwindle convergent water outlet 1-2 by guide shell 1, but counterweight floating drum 4 is equipped with the submersible machine 2 of impeller 3, thread sealed closure 5, and shack 6, chain 7 constitutes.Wherein, described guide shell 1 is connected with the inner described submersible machine 2 that impeller 3 is housed, but described guide shell 1 both sides and described counterweight floating drum 4 are connected likeness in form " aircraft both wings ".But the mediate cylindrical two ends that are shaped as of described counterweight floating drum 4 are cone, and wherein an end has described thread sealed closure 5, and waist is welded with described shack 6, and described shack 6 is by described chain 7 traction location.
The working process of present embodiment is: the horizontal type froth breaker of present embodiment is placed in after foam in the water of aeration tank gathers the district, because the buoyancy of the described floating drum 4 after the counterweight, described guide shell 1 laterally is suspended under the liquid level along water (flow) direction.During work, described submersible machine 2 drives described impeller 3 high speed rotating, push the water in the described guide shell 1 to the place ahead fast, form negative pressure in the tube, near the described guide shell 1 water-in 1-1 foam is sucked, after described impeller 3 fragmentations, discharge forward, hightail former foam regions, thoroughly eliminate the phenomenon that broken foam gathers once more.Owing to form suction function, continuously flow in described guide shell 1 cavity away from the foam of described guide shell water-in 1-1, thereby can eliminate whole foams of aeration tank " dead angle " gradually.
