Abstract

The invention discloses a butterfly robot type blower, which comprises a blower air chamber which is enclosed by a gearbox (1), a shell (12) and a cover plate (15), the blower air chamber is separated into two portions which are a left air chamber (17) and a right air chamber (18) by an end surface sleeve shaft blade (13) and a spline sleeve shaft blade (14), the two portions are alternately changed along with the movement of the blade, the blower air chamber is driven by a transmission mechanism, two blades back and forth do a synchronous approximate half cycle butterfly robot type rotation whose turning direction is opposite in the air chamber, the volume of the left and the right air chambers are alternately expanded and pressed, an inspiration port and an exhaust port are separated through an air valve (16), thereby achieving the purpose of blowing outwards, and overcoming the defects existing in a high voltage blower of the prior art that wind pressure is difficult to further increase, the air loss rate is large, the wear is severe, the noise is incredible, and a muffler is needed to arrange.

Description

technical field [0001] The invention relates to a high-pressure blower, specifically a butterfly blower blower used in metallurgy, petrochemical, papermaking, building materials, food, electronic industries and other places that require high-pressure blowing to provide high-pressure and large-volume wind sources. Background technique [0002] The high-pressure blower of prior art mainly contains two types of Roots blower (Fig. 8) and Yip's blower. The Roots blower is a fixed-volume rotary blower, which uses a rotator (a pair of orthogonally assembled "8"-shaped involute rotors that rotate in opposite phases) to make a rotary motion in the casing to suck in air and then squeeze it out. Therefore, higher wind pressure can be generated. Its characteristic is that the air volume hardly changes with the change of wind pressure. It is suitable for the occasions where the wind pressure is relatively stable and the wind pressure is high. The highest wind pressure of the Roots blowe...
