Abstract
The utility model relates to an under water aerator. In the existing aerator, a water outlet and a water intake guide funnel has a smaller distance. The existing aerator easily causes gas bearing current short circuit in working, so that the oxygen-charging effect and the cover area of the bubble of the aerator are influenced directly. The existing aerator has no a dirt preventing isolation device, so the sundries are easily sucked in a pump case to bind a blade wheel to affect the normal work of the whole machine. The utility model comprises a motor, a guiding distributor above the motor, a pump case, a blade wheel on a motor shaft, and an air inlet pipe corresponding to the blade wheel, wherein the blade wheel is positioned in the pump case. The utility model is characterized in that the upper end of the pump case is connected with a sleeve and a drain grating in sequence. The aerator has good effect of oxygen-charging and large cover area of the bubble; the drain grating can effectively prevent the dirty and ensure the normal work of the aerator.
Description
[technical field]
The utility model relates to a kind of aerating apparatus that is used for water treatment, aerator under especially a kind of liquid.
[background technology]
At present, in industries such as sewage purification processing, aquaculture, oxygen increasing pump is used widely, publication number is the technical scheme that the utility model patent of CN2408678Y promptly discloses a kind of underwater jet aeration machine, it comprises pump case, the impeller on the motor shaft and the inlet pipe corresponding with impeller of motor, motor top, described impeller is positioned at pump case, and pump case is provided with water outlet, and the pump case upper end connects the water inlet guide funnel.The aerator of this structure, close together between its water outlet and the water inlet guide funnel, easily cause the gassy water flow short-circuit during work, make the part bubble of discharging be sucked water-in once more, directly influence the oxidation effect and the bubble area coverage of aerator from water outlet.In addition, owing to do not block dirty disrupter on the water inlet guide funnel, foreign material easily are inhaled into pump case and twine impeller, even the blocking aeration machine, influence the complete machine works better.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the technological deficiency that currently available products exists, and a kind of oxygen-transfer efficiency height is provided and has aerator under the liquid that blocks dirty function.
The technical scheme that the utility model is taked is: aerator under the liquid, comprise impeller and the inlet pipe corresponding on the directed dispenser of motor, motor top and pump case, the motor shaft with impeller, described impeller is positioned at pump case, it is characterized in that pump case upper end joint sleeve, trash rack successively.Its middle sleeve can carry out length adjustment according to the actual depth of water.During work, the slit of trash rack is as water-in, the rotation of driven by motor impeller produces negative pressure, make current be inhaled into pump case from the slit of trash rack, with from the air of inlet pipe in the stirring of impeller, shear under with the current thorough mixing after spray in the waters towards periphery from directed dispenser again, reach the aeration aerating purpose.Therebetween, sleeve increases the distance between the water outlet of water-in and directed dispenser, has prolonged the circulating path of band air water stream, provides adequate time for the oxygen in the bubble dissolves in current, and oxidation effect is good, and area coverage is big; Trash rack can also effectively stop dirt, guarantees the aerator works better.
As to further the improving of technique scheme, on trash rack, support cover plate and connect floating drum, to absorb the vibration energy in the aerator working process by one; The inlet pipe lower end is provided with negative pressure cover, guarantees air and current thorough mixing, and the inlet pipe upper end is provided with sourdine, and sourdine is positioned on the water surface during work, can reduce the noise that is produced when air-flow enters inlet pipe effectively.
The utility model has increased the distance between water-in and the directed dispenser water outlet by in pump case upper end joint sleeve, trash rack successively, and the circulating path of band air water stream is prolonged, and oxidation effect is good, and the bubble area coverage is big; And trash rack can stop dirt, assurance aerator works better effectively; Simultaneously, the setting of sleeve floating drum and sourdine can absorbing vibration and reduce noise.
[description of drawings]
Fig. 1 is a kind of structural representation of the present utility model.
[embodiment]
As shown in the figure, aerator of the present utility model is followed successively by motor 11, directed dispenser 13, pump case 12, sleeve 6 and the trash rack 5 that connects by flange from bottom to top, connect impeller 8 on the motor shaft 9, impeller 8 is positioned at pump case 12 and the directed dispenser 13 common cavitys that form, water outlet 10 be evenly distributed in directed dispenser 13 bottoms around; Floating drum 4 is connected trash rack 5 tops; Inlet pipe 3 is fixing by supporting cover plate 2, and its upper end connects sourdine 1, and the lower end connects negative pressure cover 7, and the opening end of this negative pressure cover 7 is corresponding with impeller 8.
During use, under the floating drum effect, the floating drum of aerator submerges with the lower section in the water, and sourdine is positioned on the water surface, connects motor power and gets final product work.
