Energy-saving and noise-reducing type explosion-proof fan

Abstract

The invention belongs to the technical field of fans, and provides an energy-saving and noise-reducing type explosion-proof fan. Air inlet speed regulation is carried out according to the temperature of a controlled motor, so that the energy consumption is reduced, and the noise problem is relieved. According to the technical scheme, a fan motor is fixed on a base; an output shaft of the fan motor extends into a volute; an impeller is fixedly installed at the shaft end of the output shaft; the bottom end of the volute is fixed on the base; a conical cylindrical air inlet cylinder is fixedly installed in the middle of the front end face of the volute; a small-diameter opening in the rear end of the air inlet cylinder is located inside the volute and corresponds to the impeller; a large-diameter opening in the front end of the air inlet cylinder is located outside the volute and is fixedly provided with an air inlet box; the base is fixed on the controlled motor; the position, corresponding to the lower part of the impeller, of the bottom end of the volute penetrates through the base and communicates with the interior of the controlled motor; a temperature control system is arranged on one side of the fan motor; a temperature sensor is installed inside the controlled motor; the output end of the temperature sensor is connected with the input end of the temperature control system; and the output end of the temperature control system is connected with the input end of the fan motor.

Description

technical field [0001] The invention relates to an energy-saving and noise-reducing explosion-proof blower fan, which belongs to the technical field of blower fans, and specifically relates to energy-saving improvement of blower blowers. Background technique [0002] At present, the fans used in the market have the problems of high noise and high power consumption. When the temperature of the motor is low, less air volume is needed to achieve the purpose of cooling down. However, because the power of the fan in the market cannot be adjusted, the temperature of the motor is low. Higher power is still used to drive the fan, resulting in power loss. At the same time, because the fan is in a state of high-power and high-speed rotation, the noise generated is also very large. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and the technical problem to be solved is: to provide an energy-saving and noise-reducing explosion-proof fan, ...
