Abstract

The utility model relates to a multipurpose high efficiency stereo oxygen increasing machine which is an oxygen-enriching device used for aquaculture. The oxygen increasing machine is composed of an improved submersible pump, an upper and a lower blade wheels, water wings and an air inlet pipe. The special submersible pump body is arranged in the water wings and supported by the water wings and the floating frame. The utility model can enhance the oxygenation effect of the upper layer, the middle layer and the lower layer of the water body by the function of the upper and the lower blade wheels and the inlet hole, and solve the existing problem that the existing oxygen increasing machine is bulky and noisy and the blade can hurt the fish.

Description

The three-dimensional aerator of multipurpose efficient

The utility model relates to field of mechanical technique, is used for the equipment of water body oxygenation in the aquaculture.

Aerator is the indispensable key equipment that increases oxygen in the culture fishery to aquatic products, existing aerator is generally all stirred by paddle and blocks water body and reach the oxygenation purpose, its oxygenation effect often depends on the stirring scope of paddle, thereby the unavoidable volume of these aerators is big and heavy, noise is loud, energy consumption is big, and the aquatic products of also easily damaging of paddle under water, still not ideal enough with regard to its oxygenation effect in addition.

The utility model has proposed a kind of multipurpose efficient main body aerator at above-mentioned weak point, and purpose is improving oxygenation effect, also reduce equipment volume simultaneously, alleviate its weight, make it have no mechanical noise pollution again, mechanical breakdown is few, does not hinder advantages such as fishes and shrimps.

The utility model is to reach its goal of the invention by following technical characterictic.

Given accompanying drawing has three:

Fig. 1 is the utility model general structure schematic diagram

Fig. 2, Fig. 3 are that the utility model parts water knockout drum assembly is faced, vertical analysis structural representation

Fig. 4, Fig. 5 be on the utility model parts the impeller assembly vertical, face the analysis structural representation

Fig. 6, Fig. 7 are the utility model parts inferior lobe wheel assembly analysis structural representations

Among the figure: 1 for following impeller, 2 be air inlet pipe, 3 for special immersible pump, 4 for water wing, 5 for outlet pipe, 6 for water knockout drum, 7 for last impeller, 8 for axle, 9 for bearing, 10 for apical cap, 11 for output shaft under the motor, 12 for scaffold, 13 for the water knockout drum blade, 14 for last impeller blade, 15 be the inlet opening.

As seen from the figure, the utility model mainly is made up of special immersible pump 3, last impeller 7, following impeller 1, water wing 4 and air inlet pipe 2.And in the pump housing position water wing 4 of special immersible pump 3, and hold up by water wing 4, scaffold 12 and vertically to be equilibrated in the water body.Alleged special immersible pump is that thereunder motor output shaft is equipped with down impeller 1, and the inlet opening 15 that water entering section was arranged by garden week constitutes, and the top is an outlet pipe 5.The top of above-mentioned special immersible pump is a water knockout drum 6, and impeller 7 and apical cap 10 are installed again on it.Air inlet pipe 2 is stretched to place, the back side (see figure 1) of impeller 1 under water along immersible pump 3.Parts water knockout drum 6 of the present utility model is made up of several blades 13, and blade 13 is impartial arrange (the seeing Fig. 2, Fig. 3) of same crooked radian direction.The blade 14 of its last impeller is en plaque, and it is domatic vertical substantially with water knockout drum blade 13 crooked radian faces that its plate is installed, and the quantity of last impeller blade 14 is twices of water knockout drum blade 13.

The course of work of the present utility model is as follows:

Complete machine is put into the water precalculated position, make by the water wing location of foamed plastics with things such as nylon ropes again as charges, connect power supply, immersible pump is started working, then to enter outlet from the inlet opening excessive near the water the pump housing stage casing, the camber blades of the band radian of water knockout drum (being counterclockwise crooked among Fig. 2) force water body to do the rotation direction ejection towards last impeller, last impeller is then made fast rotational (according to figure Fig. 4 under the water body impetus, Fig. 5 should do the clockwise direction rotation), water water curtain is in the form of sheets thrown to the water surface, form current and wave, water curtain aloft simultaneously, the contact area that has increased water and oxygen has increased the dissolved oxygen amount in the water, the upper strata oxygenation of the three-dimensional oxygenation effect of Here it is the utility model, to be exactly that the water surface is shallow locate the water absorption course of intaking below 30 centimeters in its middle level oxygenation, make " stagnant water " become " running water ", the process that springs up of water is exactly an oxygenation process.Lower floor's oxygenation is achieved in that the following impeller high speed rotating that is installed in output shaft under the motor, positive separately water body, and the back side produces negative pressure, then sucks by air inlet pipe, then makes lower floor's water body produce water, the mixed state of gas.As fully visible, when the utility model immersible pump is worked, but the 3 layers of water body in upper, middle and lower, the while can both mix with air, reaches the purpose of main body oxygenation, has improved oxygenation effect greatly.And compare with existing market finding aerator, the advantage that volume is little, in light weight, noiselessness pollutes, energy consumption is little, do not hinder aquatic organism is arranged.As pull down oxygen-increasing device and can make water pump use, a tractor serves several purposes again.

The model machine of this aerator having reached the anticipation effect really with village kith and kin's fish pond is on probation, is subjected to user's praise through the designer.
