Description

Technical Field

[0001] The utility model relates to the technical field of hot air unit devices, in particular to an explosion-proof electric hot air unit for mining. Background Art

[0002] Hot air blower is the first choice for upgrading the heat source of modern industry. Electromechanical equipment is the best hot air source configuration for automatic machinery such as hot air conveying furnace, drying furnace, oven, packaging machine, etc. The hot air blower consists of three parts: blower, heater and control circuit. It realizes the regulation of working temperature and air volume. In addition, the hot air blower also sets over-temperature protection circuit for the air inlet and motor of the fan and emergency brake switch for the main circuit to further improve the protection of the equipment. After power is turned on, the blower blows air into the heater, so that the air passes evenly from the inside and outside of the spiral heating wire. The heat generated by the heating wire after power is turned on exchanges heat with the cold air passing through, so that the air temperature at the air outlet increases, and the K-type thermocouple at the air outlet promptly feeds back the detected air outlet temperature to the temperature controller;

[0003] When the current electric hot air unit is used underground, due to the influence of the environment, gravel is prone to fall from the bottom of the mine, causing damage to the device. At the same time, its appearance and internal components will be affected by corrosion, affecting its service life.
