Abstract

The utility model discloses a kind of squelch type aerator, and it includes sealing container, air inlet pipe, motor, blower fan, bearing and escape pipe.By the way that motor and blower fan are located in sealing container, during use, the liquid such as water are contained in sealing container, because motor, blower fan are all located in liquid, noise caused by operation is refracted back in liquid at the interface of air and liquid, without in incoming air, and the interface of liquid and sealing container cell wall is also equally by noise bounce back, thus can reach the effect for the sound that goes out.And motor and blower fan etc. are all located in liquid, operationally, liquid also acts as the effect of coolant, can be cooled, and prevents that plant running temperature is too high, ensures the stability of plant running.Further, because directly using liquid cooling noise reduction, without using the mechanism such as other sound breaks or soundproof factory building, and body is located in sealing container, is not take up excessive space, thus the squelch type aerator can effective utilization space.

Description

Squelch type aerator

Technical field

Liquid aeration field is the utility model is related to, more particularly, to a kind of squelch type aerator.

Background technology

Water body aeration generally comprises the aeration modes such as centrifugal blower aeration, submersible jet aeration at present.

Centrifugal blower aeration is to use the air blower with certain air quantity and pressure to utilize connecting conveying pipe road, by air Force to be added in liquid by micropore air dipelling disk or micropore diffuser, liquid-to-air is fully contacted, be mainly used in water The production cultivation occasion such as blast aeration and water process blast aeration.Centrifugal blower aeration has certain air quantity, the purpose of aeration It is to make to increase enough dissolved oxygens in liquid, to meet the needs of aerobe etc. is to oxygen；And need that there is enough pressures Power, aeration process are the transmittance process of molecular mass between gas and liquid, gas is fully spread and is contacted in a liquid And preventing suspended substance in liquid from sinking, centrifugal blower must can produce enough pressure.

Submersible jet aeration needs design specialized water pump, air induction conduit, nozzle carrier, blower fan, anemostat to be formed, liquid warp The nozzle carrier for being connected to pump discharge injects at a high speed blower fan, and air is guided to blower fan by air induction conduit and combined with liquid, through anemostat Discharge.Deep water self-sucking underwater jet aerator makes aqueous agitation, and bubble is fine and closely woven, can both obtain higher with being oxygenated while carrying out Oxygen transfer rate, there is impeller again without blocking advantage.Strong one-way fluid flow, cause effective convection circulation, and motor load With varying less for liquid level, therefore, it is more suitable for applying in the pond that liquid level changes greatly.

But the problem of noise is big, temperature is high, stability is poor during traditional aerator generally existing operation.

Utility model content

Based on this, it is necessary to the squelch type aerator that noise is small when providing a kind of operation, temperature is relatively low and stability is good.

A kind of squelch type aerator, including sealing container, air inlet pipe, motor, blower fan, bearing and escape pipe；Wherein, institute State sealing container be used for contain at least partly submerge the liquid of the motor, the blower fan and/or the bearing, the sealing appearance Utensil has an entrance and exit, and the air inlet pipe connect through the entrance and with the air inlet of the blower fan, the escape pipe and The gas outlet of the blower fan connects and passes through the outlet；The blower fan is located in the sealing container by the bearing；Institute State motor to connect with the blower fan in the sealing container, to arrange from the air inlet pipe air-breathing and from the escape pipe gas Go out.

In one of the embodiments, part of the air inlet pipe in the sealing container is provided with muffler.

In one of the embodiments, the inlet end of the air inlet pipe is provided with muffler.

In one of the embodiments, part of the escape pipe in the sealing container is provided with muffler.

In one of the embodiments, the rest base is located at the bottom of the sealing container by Shockproof gasket.

In one of the embodiments, the liquid is water.

In one of the embodiments, the motor is located at the top of the blower fan.

In one of the embodiments, connected between the motor and the blower fan for direct type.

In one of the embodiments, the motor is sealed with the blower fan connecting portion by O-ring seal, to prevent The liquid enters internal body.

In one of the embodiments, the motor and the blower fan are automatic de- structure or non-cohesive de- structure.

Above-mentioned squelch type aerator is by the way that motor and blower fan are located in sealing container, when in use, in sealing container The liquid such as water are contained, because motor, blower fan etc. are all located in liquid, noise caused by operation is rolled at the interface of air and liquid It is emitted back towards in liquid, without in incoming air, and the interface of liquid and sealing container cell wall is also equally by noise bounce back, thus The effect for the sound that goes out can be reached.And motor and blower fan etc. are all located in liquid, operationally, liquid also acts as the work of coolant With can be cooled, prevent that plant running temperature is too high, ensure the stability of plant running.Further, because directly using liquid Body cooling noise reduction, without using the mechanism such as other sound breaks or soundproof factory building, and body is located in sealing container, is not take up More spaces, thus the squelch type aerator can effective utilization space.
