Three-vane synchronous reciprocating blower

Abstract

The invention discloses a three-vane synchronous reciprocating blower, which consists of a machine foundation (7), a shell (12), a machine cover (13) and three or a plurality of independent blower air chambers which are formed by enclosure of three or a plurality of air valves (8) and have equal volume, wherein, three or a plurality of vanes (11) divide the three or the plurality of respectively independent air chambers into two parts of left air chambers (15) and right air chambers (16) the volumes of which are alternately changed along with the motion of the vanes (11); a driving mechanism converts circumferential rotation into reciprocating rotation and drives the three or the plurality of vanes (11) to perform synchronous reciprocating rotation in the three or the plurality of independent air chambers; the volumes of the respective left air chambers and the respective right air chambers are synchronously and alternately expanded and compressed, and separation of a suction channel and an exhaust channel is realized through the three or the plurality of air valves (8) which are provided with automatic start and stop one-way torsion spring valves; air is gathered and outputted through an air channel concentrator (14), thereby the aim of external blasting is achieved. The three-vane synchronous reciprocating blower overcomes the defects in a high pressure blower in the prior art that: the wind pressure is difficult to be further improved; the air loss rate is large; the abrasion is severe; the noise is astonishing and a silencer is required to be assembled.

Description

technical field [0001] The invention relates to a high-pressure blower, specifically a three-leaf synchronous reciprocating blower that is used in metallurgy, petrochemical, papermaking, building materials, food, electronic industries and other places that require high-pressure blowing to provide high wind pressure and large air volume. blower. Background technique [0002] The high-pressure blower of prior art mainly contains Roots blower ( Figure 8 ) and Yip's blower two types. The Roots blower is a fixed-volume rotary blower, which uses a rotator (a pair of orthogonally assembled reverse-rotating "8"-shaped involute rotors) 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 pressu...

Problems solved by technology

[0003] This type of high-pressure blower has the difficulty of further increasing the wind pressure, and when the wind pressure is high, the gas leakage rate is large, the wear is serious, and the noise is alarming. It is necessary to install a muffler; Higher processing requirements lead to higher costs
