High-sealing gas pressurization centrifugal blower

Abstract

The invention relates to the field of blowers, and particularly relates to a high-sealing gas pressurization centrifugal blower. The high-sealing gas pressurization centrifugal blower comprises a volute and a motor, wherein a rotating shaft hole is formed in the side, close to the motor, of the volute; a rotating shaft of the motor is inserted into the rotating shaft hole; the outer side of the area, positioned in the rotating shaft hole, of the rotating shaft is sleeved with a gas seal bush; a gas seal base is further arranged between the gas seal bush and the rotating shaft hole; a gas sealpressing plate arranged on the outer side of the gas seal bush in a sleeving manner is further arranged on the end face, close to a cavity, of the gas seal base; the gas seal base and the gas seal pressing plate are fixedly connected with a motor base connecting piece through fixing bolts; and a gas seal area exists in the area defined by the gas seal bush, the gas seal base and the gas seal pressing plate. The high-sealing gas pressurization centrifugal blower overcomes the defect that according to a gas pressurization centrifugal blower in the prior art, the joint of a rotating shaft and a machine shell is prone to being not sealed tightly, and consequently gas leakage is caused, the problem that the rotating shaft of the motor and the machine shell are not sealed tightly can be effectively solved, and gas leakage is effectively prevented.

Description

technical field [0001] The invention relates to the field of blowers, in particular to a high-tight gas pressurized centrifugal blower. Background technique [0002] The gas blower is a special power equipment for transporting gas in the coke oven gas purification process. It is generally installed after the initial cooling of coke oven gas, and it is also installed at the end of the gas purification process. The gas blower is the core equipment of the coke oven gas transmission and purification system in the coking plant. Once it is shut down, it will not only affect the normal production of the coke oven and chemical production processes, but also cause the gas to be out of balance in the whole company, affecting the sintering, ironmaking and steelmaking systems normal operation, so it is very important. [0003] There are two types of gas blowers: volumetric and centrifugal. Centrifugal blowers, also known as turbine blowers, are the most commonly used blowers in coking...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defect that the gas booster centrifugal blower in the prior art is prone to loose seal at the connection between the rotating shaft and the casing, resulting in gas leakage, and provides a high-sealing gas booster centrifugal blower, which can effectively Prevent the problem of poor sealing between the motor shaft and the casing, effectively preventing the leakage of gas
