Abstract

The invention provides an explosion prevention and noise elimination integrated intelligent speed regulating local fan. The explosion prevention and noise elimination integrated intelligent speed regulating local fan comprises a fan shell of a barrel-shaped structure, a drainage apparatus is arranged at one end of the fan shell, and a current collector is arranged on the inner side of the drainage apparatus; a fan linear temperature speed regulating device is arranged at the other end of the fan shell; and a first-stage explosion prevention motor and a second-stage explosion prevention motor are further arranged in the fan shell, the axial directions of the first-stage explosion prevention motor and the second-stage explosion prevention motor are parallel to the length direction of the fan shell, a rotating shaft of the first -stage explosion prevention motor right faces a rotating shaft of the second-stage explosion prevention motor, and the rotating shafts of the first-stage explosion prevention motor and the second-stage explosion prevention motor are each provided with an impeller. Defects of an existing local fan are overcome. The explosion prevention and noise elimination integrated intelligent speed regulating local fan belongs to the technical field of ventilating devices.

Description

technical field [0001] The invention is a ventilating device, specifically an intelligent speed-regulating local ventilator integrating explosion-proof and noise reduction. Background technique [0002] First of all, the current ventilation work of coal and rock roadway excavation is mainly realized by press-in local fans, whose main function is to dilute and eliminate toxic and harmful gases in the excavation work space and supply fresh air flow to the excavation work space. Commonly used ventilators have the disadvantage of low wind pressure. Most of the commonly used ventilators are first-class ventilators. When long-distance ventilation is required, the ventilators must be moved to increase the distance of conveying air flow. Moreover, cast steel impellers are often used, which have a large weight and low fan efficiency. There is a need for a high-efficiency ventilator suitable for long distances. [0003] Secondly, domestic ventilators are basically used in relatively...
