The pressurized coal gas blower provided by the invention comprises a base, a compressor body, a motor, a transmission, a coupler, a main shaft, a seal component, a closed-type impellor, an enclosure and an air inlet, wherein the compressor body is installed on the base of the blower; the motor and the transmission are also connected the base; the motor and the transmission are connected through the coupler; a seal component is installed on the shaft end of the main shaft; the main shaft is provided with a shaft gear; the closed-type impellor is installed behind the shaft gear; and the enclosure is externally provided with an axial air inlet. The pressurized coal gas blower provided by the invention is reasonable in structure, has high efficiency, is low in energy consumption, has good seal performance, can effectively prevent harmful gas from leaking and prevent explosion accidents from happening, and protect the atmospheric environment and human safety.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of blower fan, be specifically related to a kind of pressing gas blower.
Background technique
The pressing gas blower is mainly used in conveying, the pressurization of coal gas, and there are shortcomings such as efficient is low, sealing difference in existing gas-blowing engine.Because the medium that blower is carried is a coal gas; Has inflammable and explosive property; Under the operating mode use condition of high rotating speed, high pressure, cause gas leakage or explosive accident easily; Therefore very high to the requirement of blower fan sealing, structural material, should prevent extraneous air through blasting in the shaft end seal entering machine He behind the coal gas volume mixing certain proportion, prevent that again the interior coal gas of machine is to external leakage.
Summary of the invention
Goal of the invention: for solving the deficiency of existing technology, the present invention provides a kind of efficient height, pressing gas blower low, good airproof performance consumes energy.
The technological scheme that the present invention adopts: a kind of pressing gas blower; Comprise base, compressor body, motor, speed changer, coupling, main shaft, sealed member, double shrouded wheel, casing, intake grill; Compressor body is installed on the base plate, also is connected with motor, speed changer on the base, motor links to each other through coupling with speed changer; Said main-axis end is equipped with sealed member; Main shaft is provided with shaftgear, and double shrouded wheel is installed behind the shaftgear, and said casing is provided with axial intake grill outward.
As preferably, described coupling is elastic coupling flexible coupling or diaphragm coupling.
As preferably, described sealed member is the triple seal structure, comprises that labyrinth seal, the sealing of floating type carbocyclic ring, nitrogen purge sealing.
As preferably, described double shrouded wheel blade adopts backward bending type list circular arc molded lines or three-dimensional flow vane type line.
As preferably, described shaftgear flute profile is single circular arc monocline tooth, and material is an Alloy Constructional Steel.
As preferably, be provided with a flanged (FLGD) through hole at the axle head position that sealed member is installed, the sealed chamber of this hole UNICOM shaft end seal is inflated by this hole inward, reduces leakage thereby can make labyrinth seal become pneumostop;
As preferably, described double shrouded wheel is welded to one another shaping or blade and wheel disc integral body by wheel cap, blade and wheel disc and mills and process after the shape and the wheel cap welding.
Blower fan provided by the invention is the blower fan of high rotating speed, high pressure, and rotation speed of fan reaches 9850r/min, and the draught fan impeller linear velocity surpasses 300r/min, and the dust loading of fed sheet of a media is not more than 10mg/Nm
