Anti-blockage ventilator for mines and wells

Abstract

The invention relates to the technical field of mine machinery, and discloses an anti-blockage ventilator for mines and wells. The anti-blockage ventilator comprises a casing, wherein ventilating heads are respectively fixedly arranged at both ends of the casing; inner plates are respectively fixedly arranged at the front sides of the two air ventilating heads; the diameter of each inner plate isgreater than the diameter of the casing; two limiting holes are formed in the middle part of the inside surface of each ventilating head, and are symmetric to the center of the corresponding ventilating head; the outer surface of each inner plate is movably connected with a protective cover; a vertical rod is fixedly arranged at the outer surface of each protective cover. The anti-blockage ventilator for the mines and wells has the advantages that by arranging a slide gear, and utilizing the cooperation of a slide block and a gear, each limiting rod can be moved out of the corresponding limiting hole, so as to conveniently replace the corresponding protective cover; the decreasing of the ventilating efficiency of the ventilator due to attaching of dust at the surface of each protective cover is avoided; the practicality of the ventilator is improved.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to an anti-clogging ventilator used in mines. Background technique [0002] Fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Modern fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Ventilation , Dust extraction and cooling, ventilation and induction of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grain, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0003] When the mine ventilator is used to ventilate the mine tunnel, certain dust will be generated due to the mining of the mine, and the existing mine ventilator does not have a protective cover. When the ventilator is in use, the dust will float into the ventilator with the air, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-clogging ventilator used in mines, which has the advantages of anti-clogging, convenient cleaning and easy installation, and solves the problem that the existing mine ventilator has no protective cover and the ventilator is in use. The dust will drift into the ventilator with the air, and the efficiency of ventilation will decrease with the long-term operation. Moreover, after a long time, the inside of the ventilator will become very dirty. The existing mine ventilator does not have The cleaning device is a very troublesome problem through manual cleaning
