Description
Technical field
The present invention relates to environmental technology field, specifically the oxidation ditch of foam is eliminated in jet extruding.
Background technology
Oxidation ditch passes into the waste disposal plant in air to sewage lagoon, sewage being carried out to oxygenation process, in the process of oxidation ditch process, often can produce a large amount of foams, for above-mentioned foam, generally do not process it or adopt defoamer to process.The major cause of bubbling there is partial chemical product composition in waste water.This kind of chemical component is cut into small molecules under the hydraulic shear effect that low pressure stream aerating system is stronger, in conjunction with tiny bubble thus formed foam.Foam to there is hazard ratio comparatively large, flowing out as taken partial sludge out of, easily making sludge reflux amount large, increasing cost; Reduce oxyty, be unfavorable for the growth etc. of aerobic flora; And to solve the method for foam be add defoamer in the aeration tank of routine, and for most sewage, the chemical component of its inside is complicated, and the chemical component in sewage is comparatively large on the impact of defoamer, and therefore, the result of use of defoamer is also not obvious.
Summary of the invention
Jet extruding is the object of the present invention is to provide to eliminate the oxidation ditch of foam, this device utilizes the defoaming device loading rotation on oxidation ditch, utilizes mechanical rubbing effect, breaks bubble, thus eliminate a large amount of foams, this effect is more obvious than using the defoaming effect of defoamer.
The object of invention is achieved through the following technical solutions: the oxidation ditch of foam is eliminated in jet extruding, comprise oxidation ditch body, oxidation ditch body comprises oxidation ditch A side wall and oxidation ditch B side wall, oxidation ditch A side wall is provided with bearing support A, oxidation ditch B side wall is provided with bearing support B, also comprise rotation axis, rotation axis through-shaft bearing A and bearing support B and rotation axis freely can rotate in bearing support A and bearing support B, rotation axis one end is connected with motor, the rotating output shaft of motor is connected with rotation axis, and motor-driven rotation axle rotates; The periphery of rotation axis is provided with some broken bubble rods, the broken axis of bubble rod and the axes normal of rotation axis; Rotation axis is the pipeline of hollow, and rotation axis is communicated with air feed pump away from one end of motor, and rotation axis also has some outgassing micropores, and outgassing micropore is arranged on region between adjacent broken bubble rod.
The principle that said structure realizes eliminating foam is: utilize motor, bearing support A, bearing support B, rotation axis to form rotational structure, motor-driven rotation axle carries out high speed rotating, bearing support A, bearing support B play the effect of support rotating axle, utilize the broken bubble rod on rotation axis and foam contacting, directly foam is poked, thus reach the object eliminating foam fast.Utilize air feed pump that air-flow is sprayed from outgassing micropore, thus extruding 2 adjacent outgassing micropores between foam, foam is raised, thus be conducive to broken steep rod poke foam, defoaming effect gets a promotion further.
Preferably, due to foam group, be formed by the bubble coalescence that diameter is very little mostly, the broken bubble rod therefore in the present invention should select the structure that diameter is very little, and therefore the diameter dimension of described broken bubble rod is the span of P, P is 1mm to 5mm.
Preferably, broken bubble rod is arranged to conical tip away from one end of rotation axis, is arranged to most advanced and sophisticated favourablely poke foam.
Preferably, along 2 on rotation axis axis direction, the gap of an adjacent broken bubble rod remains on 1cm to 2cm scope.
Preferably, broken bubble rod be metal bar or the rope made of hemp or cloth, due to when broken bubble rod be metal bar, easily makes to generate secondary foam, therefore should preferably select in concrete enforcement the rope made of hemp or cloth excellent as broken bubble, or have metal bar, the rope made of hemp, cloth mixing setting.
The invention has the advantages that: structure is simple, and cost is low, simple and quick, and defoaming effect is obvious.
