Abstract
The invention relates to a sewage air flotation scum defoaming machine which comprises a motor, wherein the motor is connected with a rotating rod through a speed reducer and a coupler; the rotating rod is reversely T-shaped; a plurality of fixed vertical shafts are distributed on a transverse rod of the rotating rod; blades capable of rotating around the fixed vertical shafts are arranged on the fixed vertical shafts. The sewage air flotation scum defoaming machine can release air bubbles in scum in a horizontal direction and a vertical direction, so that the bubble breakage speed and the sinking speed of the scum are greatly increased, and the solid and liquid separation time is shortened; under the general condition, bubbles can be broken within 2-10 seconds according to the difference of the thicknesses of scum layers. Furthermore, full coverage for the scum layers is realized, and the scum in a large amount of water can be defoamed.
Description
Technical field
The present invention relates to a kind of sewage air-flotation scum silica frost Defoaming machine, belong to technical field of sewage.
Background technology
In sewage treatment technology, air supporting or chemical coagulation air supporting are a kind of technology and equipments that is often carried out application.The kind of airfloat equipment has a lot, but is which kind of airfloat equipment all can form at it scum silica frost that a layer thickness is different above water layer.Owing to also existing a large amount of micro-bubbles in scum silica frost except pollutent and chemical coagulation flco, so enter behind air supporting scum silica frost storage pond when these air supporting scum silica frost are scraped air floatation machine, still can swim on the water surface and be difficult to sink.In order to solve this technical barrier, people have proposed many ways, such as a low speed blade mixer is installed on the interface of scum layer, by stir the bubble in air supporting scum silica frost in addition fragmentation air supporting scum silica frost is sunk, but it is less that this way is only suitable for the water yield, in the less situation of liquid level.The in the situation that of big yield and big area liquid level, because blade of stirrer size is difficult to do greatly, done greatly fluctuation of service, and blade and scum silica frost be the broken bubble of lateral contact weak effect, so limited the scope of application of this method.Have in addition the method that air supporting scum silica frost is filtered, due to scum silica frost complicated component, thickness has bubble, easily stops up filtering material, and descum and filter material are more difficult, is difficult to maintain operation steady in a long-term.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and a kind of sewage air-flotation scum silica frost Defoaming machine is provided, go for the froth breaking demand of the sewage air-flotation scum silica frost under any water yield and any water surface area, and can realize instantaneous quick froth breaking.
The technical scheme that the present invention takes is:
A kind of sewage air-flotation scum silica frost Defoaming machine, comprises motor, and motor via reducer, shaft coupling connect revolving bar, and revolving bar, for falling " T " font, is distributed with multiple fixing vertical pivots on the cross bar of revolving bar, and on fixing vertical pivot, having can be around the blade of fixing vertical pivot rotation.
Described motor and speed reducer is located on mounting bracket, and revolving bar is under mounting bracket.
In the middle of described blade, be provided with a vertical metal tube, be inserted with fixing vertical pivot in metal tube, metal tube internal diameter is slightly larger than fixing vertical pivot external diameter, and the top of fixing vertical pivot is fixed with nut, and blade can be around fixing vertical pivot rotation.
Described blade is rectangle, and is of a size of: long 300mm～500mm, and wide 150mm～200mm, the spacing between adjacent blades is 5mm～10mm.
Described motor is adjustable rotating speed motor.
In the time that scum layer contacts with blade, whole vane group is under the drive of revolving bar, clockwise or counterclockwise at slag blanket apparent motion, because blade can be centered by rotating shaft (fixing vertical pivot), on liquid level, be subject to carrying out voluntarily under certain resistance 360 ° of rotations, and between blade, spacing is very large, thereby can guarantees that blade fully contacts with scum layer on horizontal and vertical both direction, scum silica frost is discharged fast, make scum silica frost sink down into fast bottom, scum silica frost storage pond.
Blade of the present invention can realize scum silica frost on both direction in level with vertically in the release of bubble, broken bubble and the sinking velocity of scum silica frost are greatly accelerated, shorten the solid-liquid separation time, generally according to the difference of scum layer thickness, can within 2-10 second, realize broken bubble.Accomplish all standing to scum silica frost aspect simultaneously, can meet the scum silica frost froth breaking under big yield.

Embodiment
Further illustrate below in conjunction with accompanying drawing.
A kind of sewage air-flotation scum silica frost Defoaming machine, comprise motor 1, motor 1 connects revolving bar 5 by step-down gear 2, shaft coupling 3, and revolving bar 5 is for falling " T " font, on the cross bar of revolving bar 5, be distributed with multiple fixing vertical pivots 6, on fixing vertical pivot 6, have the blade 7 that can rotate around fixing vertical pivot 6.Described motor 1 and step-down gear 2 are located on mounting bracket 4, and revolving bar 5 is under mounting bracket 4.Blade 7 is connected with the cross bar of revolving bar 5 by fixing vertical pivot 6.Motor is connected with housing.In the middle of blade 7, be provided with a vertical metal tube 8, be inserted with fixing vertical pivot 6 in metal tube 8, metal tube 8 internal diameters are slightly larger than fixing vertical pivot 6 external diameters, and the top of fixing vertical pivot 6 is fixing with nut 9, and blade 7 can rotate around fixing vertical pivot 6.
The diameter that the horizontal quantity of broken bubble rotating paddle combination can be stored up pond according to scum silica frost is adjusted, and the rotating paddle at two ends, apart from the about 2-5cm of distance of circular pond pool wall, therefore can avoid occurring broken bubble dead angle in the scum silica frost aspect in pond.
1) blade length of vane group can be adjusted according to the thickness size of scum layer, guarantees in the time that maximum ga(u)ge appears in scum layer, and blade length also will grow 15～25cm than slag blanket, avoids occurring brokenly bubble dead angle.
2), because vane group quantity can constantly increase according to scum silica frost amount, therefore the length of Defoaming machine revolving bar can increase to tens meters even tens meters long from several meters, accomplishes all standing to scum silica frost aspect, can meet the scum silica frost froth breaking under big yield.
3) revolving bar is metal or a nonmetallic round bar that diameter is less, and each on revolving bar can be carried out 360 ° around blade of fixing vertical pivot rotation and rotated freely on scum layer, the operation power that therefore this machine consumes is more much smaller than traditional fixed " extremely " blade energy consumption.
4) blade is to be made up of stainless steel substrates or engineering plastic tablet through polishing, therefore in the time of operation, can not adhere to air supporting scum silica frost.
5) rotating speed of Defoaming machine can be conditioned, to be adapted to the froth breaking of the air supporting scum layer to different viscosityes and different thickness and to carry out energy-conservation.
Before device start, sewage air-flotation scum silica frost flows into scum silica frost storage pond successively, when under the identity distance blade of the scum layer upper bound during along 100mm～150mm, starts Defoaming machine.In the time that scum layer contacts with agitating vane, vane group is under the drive of revolving bar, clockwise or counterclockwise at slag blanket apparent motion, because blade can be centered by rotating shaft, on liquid level, be subject to carrying out voluntarily under certain resistance 360 ° of rotations, and between blade, spacing is very large, thereby can guarantees that blade fully contacts with scum layer on horizontal and vertical both direction, scum silica frost is discharged fast, make scum silica frost sink down into fast bottom, scum silica frost storage pond.
