Description
Technical field
The present invention relates to noise reduction technical field more particularly to a kind of silencing means for vacuum pump.
Background technology
Water-ring vacuum pump belongs to wet vacuum pump, is chiefly used in extracting or conveying gas, with industrial and agricultural production and scientific research
The rapid development of cause, all trades and professions are growing to the demand of water-ring vacuum pump, but vacuum pump is in use
There are following technological deficiencies：In the vacuum pump course of work, exhaust pipe is generated the higher noise of sound level by gas impact vibration,
Through technical staff's decibel instrument Preliminary detection, level of noise reaches more than 80dBA, belongs to severe in noise pollution degree, can
Different degrees of harm is caused to worker around, therefore the generation for reducing noise is very necessary.
Invention content
The purpose of the present invention is to provide a kind of silencing means for vacuum pump, big to solve existing vacuum pump noise
The problem of.
In order to achieve the above object, base case of the invention is：A kind of silencing means for vacuum pump, including outer
Shell is equipped with the partition board for shell to be divided into upper half shell and lower half shell in the shell, is equipped in the upper half shell and vacuum
The first opening that pump exhaust pipe is connected, it is also opposite in the upper half shell to set there are two magnetic opposite magnet, between two magnet
Equipped with rotatable lamella, rotatable lamella is equipped with the coil for cutting magnetic induction line, and brush is powered on the coil；In the lower half shell
Water storage cavity and filter chamber equipped with connection are equipped with the atomizing piece for making water fogging in water storage cavity, are additionally provided with and are used in water storage cavity
The circuit box of the atomizing piece high-frequency vibration is controlled, circuit box is connected with the brush, and water storage cavity is additionally provided with water inlet pipe and water outlet
Pipe；The filter chamber is equipped with the second opening and third opening.
The principle of the present invention and advantageous effect are：
1st, the exhaust pipe of vacuum pump is connected with upper half shell, and two opposite magnet of magnetism, vacuum are oppositely arranged in upper half shell
When gas in pump exhaust pipe is discharged in upper half shell, since the flowing velocity of gas is very fast, gas acts on the power on rotatable lamella
Rotate rotatable lamella, rotatable lamella rotation just cuts the magnetic induction line that two magnet generate with moving winding, generates sensing electric current, so as to for
Circuit box provides power supply.The setting of coil and magnet makes the mechanical energy of gas being converted into electric energy, reduces gas and exhaust pipe
Inner wall directly collides and generates the probability of noise.
2nd, the air inlet pipe of vacuum pump and the second open communication of lower half shell, the interior setting circuit box of water storage cavity and atomizing piece, by
It is electrically connected in circuit box and brush, the induced electricity stream that coil is done cutting magnetic induction line movement and generated by brush imported into the electricity of circuit box
Lu Zhong, circuit box work after make atomizing piece generate high-frequency resonant, the water throwing in water storage cavity is generated into water mist from the water surface, water mist into
Enter in filter chamber and the grit of the gas mixing in filter chamber is deposited in water storage cavity, reduce the grit in gas, it is true so as to make
Noise in sky pump is reduced.
In conclusion this programme is by setting coil and magnet to produce the gas that vacuum pump discharges pipe is discharged because of flowing
Raw energy expenditure reduces the generation of noise, while the energy of gas is converted into the electric energy of dedusting, makes the atomization in trash extraction box
Piece high-frequency vibration is by the water atomization in water storage cavity, thus the mixed contamination precipitation of gas at air inlet is removed, purification gas,
The noise reduction at sound source further reduces the generation of gas noise in vacuum pump.
Further, the outer wall of the upper half shell is equipped with several vacuum tubes.
Several vacuum tubes on the outer wall of upper half shell are set, since sound cannot be propagated in a vacuum, prevent one
Divide the propagation of noise.
Further, second opening is equipped with drainage plate, and the drainage plate is equipped with several and the second open communication
Intercommunicating pore.
Since gas enters the speed of filter chamber compared with block, setting drainage plate blocks the second opening, makes gas can only be from drawing
Intercommunicating pore in flowing plate enters in vacuum pump, the impurity in gas is avoided just directly to enter when not being removed by the second opening true
Dust removing effects are reduced in sky pump.
Further, the outlet pipe is hose.
Since the water in vacuum pump can also mix certain impurity, the outlet pipe of soft material is convenient for the water in pumping drawing one
In part to water storage cavity, the impurity in water in vacuum pump is removed.
Further, it is additionally provided with the drainage trough connected with water storage cavity on the drainage plate.
The effect of drainage trough is that most of water mist is enable, which to liquefy in drainage trough, forms water droplet, and water droplet is along drainage trough
Into in water storage cavity.
Further, the surface of rotatable lamella is arc.
The purpose of rotatable lamella setting camber is that increase air-flow pushes the thrust of rotatable lamella rotation, enables rotatable lamella
It rapidly rotates, so as to be rotated with moving winding, coil is enable ceaselessly to do cutting magnetic induction line movement in magnetic field, be water storage cavity
In circuit box provide electric energy.
