Abstract

The utility model discloses a rotary blower, comprising a casing (1), a rotor (2), a motor, an oil tank and separator of oil and gas. The casing (1) is a hollow tubular cavity (6) and equipped with an air inlet (3) and an air outlet (4). The rotor (2) is distributed with gleitbretter (5), and divides the cavity (6) to left working chamber and right working chamber along the axial direction, and gaps exist between the rotor (2) and two working chambers. The two working chambers are all equipped with inlet hole (8) connecting to the air inlet (3) and outlet hole (9) connecting to the air vent (4) in the opposite position. The utility model can greatly increase the discharge quantity of air, save the raw material and is convenient for machining.

Description

A kind of rotary blower

Technical field

The utility model relates to a kind of rotary blower.

Background technique

Chamber in the present rotary blower is circular, the inwall of rotor and chamber one side is tangent, when rotating, rotor is subjected to action of centrifugal force, epitrochanterian slide plate is close to the rotation of body inwall, when slide plate rotates, volume between rotor, slide plate body and the inwall increases gradually, forms negative pressure, and gas is inhaled into; Volume diminishes gradually when the volume between two slide plates reaches maximum and rotates, gas is compressed into relief opening and discharges, but rotor whenever rotates a circle, can only exhaust between two slide plates once, and be subjected to the influence of slide plate linear velocity, the maximum air output that exhaust produces can only be 7 cubic meters per minute.Also occur increasing the blower of air output in addition on the market, but this blower not only consumes more raw material, and be not easy to machining by the length that increases casing.

Summary of the invention

The utility model provides a kind of rotary blower, and it can improve air output greatly, and can save material, and is convenient to machining.

The utility model has adopted following technological scheme: a kind of rotary blower, form by casing, rotor, motor, fuel tank and gas and oil separating plant, hollow becomes chamber in the casing, on casing, be provided with suction port and relief opening, on rotor, be distributed with slide plate, described chamber is set to flat-shaped, described rotor is divided into chamber left and right sides active chamber vertically, be provided with the gap between rotor and two active chambers, on two active chambers, all be provided with inlet hole and exhaust port, inlet hole is corresponding with exhaust port, and inlet hole all is connected with suction port, and exhaust port all is connected with relief opening.

Described rotor is positioned at the axle center of chamber, and described left and right sides active chamber is identical.The cross section of described chamber is set to oblateness.The minimum diameter place of described rotor and chamber is tangent.Be provided with gas-entered passageway and exhaust passage between described casing and the chamber, the inlet hole of two active chambers is connected by gas-entered passageway about described, gas-entered passageway communicates with suction port, and the exhaust port of two active chambers is connected by the exhaust passage, and the exhaust passage communicates with relief opening.Described gas-entered passageway and exhaust passage form one along chamber outer wall and casing.

After adopting above technological scheme, rotor drives and produces once air-breathing and exhaust respectively after slide plate rotates a week in two active chambers, under the situation that does not increase casing length, increases air output effectively like this, also saves the energy simultaneously.Rotor is positioned at the shaft core position of chamber, about two active chambers identical, like this rotor relatively and chamber not eccentric, the structure on two sides symmetry, complete machine operates steadily.The inlet hole of two active chambers is communicated with by gas-entered passageway, and two exhaust ports are by the exhaust passage, and gas-entered passageway and exhaust passage and casing be integral, and the compact structure of casing is convenient to machining like this.
