Problems solved by technology

At present, the main underground ventilation equipment is a ventilator, but the existing ventilator often inhales debris during use, which causes the ventilator to malfunction, makes the underground air flow slowly, affects the working environment of the construction personnel, and the health of the construction personnel. Health is affected, and the life of the ventilator is affected when too many impurities are sucked in

Abstract

The invention belongs to the field of ventilation equipment for mining, and relates to a cleanable ventilator protective net. The cleanable ventilator protective net comprises a ventilator body. A horn-shaped opening is formed in an air inlet of the ventilator body. A primary protective net is arranged at the end of the horn-shaped opening, a support is arranged at the upper end of the horn-shapedopening, a pneumatic cylinder is fixed to the support, the pneumatic cylinder is connected with a time relay, a cleaning brush is connected to the end of a piston rod of the pneumatic cylinder, bristles of the cleaning brush make contact with the primary protective net, and the cleaning brush is obliquely arranged; the primary protective net is a long-strip type net. The protective net is reasonable in structural design, impurities can be prevented from entering a ventilator, normal work of the ventilator is effectively ensured, fresh air is supplied under the shaft in time, the ventilator body is protected, and the service life of the ventilator is prolonged.

Description

technical field [0001] The invention relates to a cleanable ventilator guard net, which belongs to the field of underground ventilation equipment. Background technique [0002] The underground ventilation system is a very important system for mine operation. If the ventilation is not good and the air volume is not enough, it is easy to cause construction workers to suffocate and die, or it is difficult to remove harmful gases underground. Effective underground ventilation can update the fresh air in the mine in time to meet the needs of personnel for oxygen; dilute harmful gases and dust in the mine to ensure safe production; adjust the climate in the mine to create a good working environment. At present, the main underground ventilation equipment is a ventilator, but the existing ventilator often inhales sundries during use, which causes the ventilator to malfunction, makes the underground air flow slowly, affects the working environment of the construction personnel, and a...
