A fan-swing type high-pressure blower

Abstract

The invention discloses a fan-pendulum-type high-pressure blower. The fan-pendulum-type high-pressure blower comprises a swinging converter (1) and a swinging draught fan (2). According to the technical scheme, a device consists of the swinging converter and the swinging draught fan, the swinging converter converts the circumference rotation of an input shaft into the reciprocating rotation of an output shaft through a gear drive swinging rod and a horseshoe-shaped rack, the swinging draught fan is provided with an air box, a draught fan shaft, a blade, an air channel, an air suction valve and an air exhaust valve, the inner cavity of the cylindrical air box is divided into a left air chamber and a right air chamber by the blade, the draught fan shaft is connected with the output shaft of the swinging converter, the draught fan shaft drives the blade to swing reciprocally in the air box along a fan-shaped trajectory, and the volumes of the left air chamber and the right air chamber are changed reciprocally in an alternating way; external air is sucked into the left air chamber and the right air chamber by the air suction valve through the air channel alternately, and the air compressed by the blade which is swung reciprocally is extruded out alternately from the left air chamber and the right air chamber through the air channel and the air exhaust valve. Therefore, the aims of improving air pressure, reducing air loss and noises, and reducing cost of the high-pressure blower are fulfilled.

Description

technical field [0001] The present invention relates to a high-pressure blower, specifically refers to a high-pressure, high-volume air source used in metallurgy, mining, tunnels, petrochemicals, papermaking, building materials, food, electronic industries and engineering, etc. that require high-pressure blowers. A fan pendulum high pressure blower. Background technique [0002] The high-pressure blower of prior art mainly contains Roots blower 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 pressure of the...

AI Technical Summary

Problems solved by technology

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

Therefore, the prior art has the problems and deficiencies of high cost, high noise, large wind loss, and difficulty in increasing wind pressure
