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

Abstract

The invention discloses a reciprocating blower with two-blade synchronous racks, which comprises a gear box (1), a belt pulley (2), a reduction gear (3), a crankshaft gear (3), a reduction gear shaft (31), a crankshaft (41), a rocking arm rack (5), a spline gear (6), a pinch roller component (61), a frame (7), an air valve (8), a spline shaft (9), blades (10), a casing (11), a cover (12) and an air duct concentrator (13). The invention overcomes the deficiencies in the prior high-pressure blower of difficulty to increase wind pressure, large windage loss, serious abrasion, amazing noise and high cost, and adopts the technical proposal that two blowing blades synchronously rotate back and forth for 150 degrees in a cylindrical casing separated into two air chambers by the air valve; air issucked into through the air valve and then squeezed out. The provided two-blade synchronous reciprocating blower ensures that the high-pressure blower achieves the purposes of further increased wind pressure (larger than or equal to 100kPa) and wind rate, small windage loss, high efficiency, low noise without the need of adding a silencer, small volume and low cost.

Description

technical field [0001] The invention relates to a high-pressure blower, specifically a two-leaf synchronous rack 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. Reciprocating 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 pressure of th...
