Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof fans, and in particular to an energy-saving explosion-proof fan. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. Commonly referred to fans include ventilators, blowers, wind turbines, and fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0003] The patent specification with announcement number CN215980012U discloses an energy-saving explosion-proof fan, including an outer shell, a mounting seat is fixedly installed on the inner bottom wall of the outer shell, an exhaust mechanism is fixedly installed on the top of the mounting seat, a cooling mechanism is arranged on the top of the outer shell, a protective plate is movably installed on the front surface of the outer shell, and locking mechanisms are rotatably connected at the four corners of the protective plate. For this energy-saving explosion-proof fan, when the inside of the outer shell is too high, a water pump is started, and the water pump can pump out water from the cooling water tank and spray it into the outer shell through a nozzle. The temperature is reduced in time through water cooling, and the cooling effect is good, which can effectively prevent internal overheating and improve the safety of the device during use. At the same time, the waterproof layer coated on the outer surface of the mounting frame can block the cooling water on the surface of the mounting frame to prevent the cold water from penetrating into the interior and causing damage to the internal exhaust motor, thereby improving the practicality of the device.

[0004] Although the above technical solution can reduce the temperature in time through water cooling, the cooling effect is good, which can effectively prevent internal overheating and improve the safety of the device during use, but in actual operation, water resources cannot be recycled, resulting in a large amount of water resources being wasted for cooling the fan. For this reason, we propose an energy-saving explosion-proof fan. Utility Model Content
