Turbocharging blower

Abstract

A turbocharging blower comprises a cylindrical shell body with two open ends. The two ends of the cylindrical shell body are in sealing connection with a front cover and a rear cover respectively, an air inlet is formed in the front cover, an air outlet is formed in the rear cover, and the two ends of a transmission shaft arranged in the cylindrical shell body are fixed to the front cover and the rear cover through bearings. A multi-head screw body is arranged on the transmission shaft, the multi-head screw body is arranged on the side face of the transmission shaft and spirally advances in the axial direction with the transmission shaft as a rotary shaft, the multi-head screw body extends from the transmission shaft front end close to the front cover to the transmission shaft rear end close to the rear cover, and the multi-head screw body and the transmission shaft are integrally connected. At least two screw blades are arranged in the multi-head screw body, the screw blades are evenly arranged on the side face of the transmission shaft along the circumference, the inner edges of the screw blades of the multi-head screw body are closely attached to the transmission shaft, and the outer edges of the screw blades are arranged close to the inner wall of the cylindrical shell body. The turbocharging blower is reasonable in structural design, stable and reliable in work, low in noise, low in manufacturing cost, large in pressure, high in efficiency and large in generated blast capacity.

Description

Technical field: [0001] The invention relates to a turbocharged blower. Background technique: [0002] There are two main types of existing blowers, one is the Roots blower, which uses two leaf-shaped rotors to move relative to each other in the cylinder to compress and transport the gas, and its disadvantages are high noise and high cost; the other is the screw blower. Its disadvantages are high noise, low pressure, small air volume and low efficiency. Invention content: [0003] In order to make up for the deficiencies of the prior art, the present invention provides a turbocharged blower, which has reasonable structural design, stable and reliable operation, low noise, low cost, high pressure, high efficiency, and large air volume, which solves the problems of the prior art. problems in . [0004] The technical scheme that the present invention adopts for solving the problems of the technologies described above is: [0005] A turbocharged blower comprises a cylindric...
