Draught fan with automatic cleaning function

Abstract

The invention discloses a draught fan with an automatic cleaning function. The draught fan comprises a water storage pond; a rear guiding pipe and a front guiding pipe fixedly communicate with the front end and the rear end of the water storage pond; the top end of the rear guiding pipe and the top end of the front guiding pipe are each fixedly provided with an electromagnetic valve; a driving motor is fixedly arranged on the middle portion of the rear guiding pipe; an output shaft of the driving motor is fixedly connected with a center shaft of fan blades; the water storage pond is fixedly connected with the upper end of a check ring through a first vibration reducing body; the bottom of the rear guiding pipe and the bottom of the front guiding pipe are both fixedly connected with the bottom end of the check ring through second vibration reducing bodies; and the side, close to the fan blades, of the rear guiding pipe and the side, close to the fan blades, of the front guiding pipe are each fixedly provided with a nozzle. The draught fan with the automatic cleaning function is reasonable in design, by means of a series of structures, the fan blades in the draught fan can be automatically cleaned, adverse effects, generated by dust on the fan blades, on the draught fan can be effectively prevented, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a fan with automatic cleaning function. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. When the fan starts to work, the vibration of the bearing part is very small, but as the running time increases, the dust in the fan will adhere to the impeller unevenly, gradually destroying the dynamic balance of the fan, and gradually increasing the vibration of the bearing. Once the vibration reaches the fan When the maximum allowable value is reached, the fan must be shut down for repair (remove dust accumulation, redo dynamic balance), because it is very dangerous at this time, and the user must not use it forcibly. The existing blower requires staff to remove the blower and manually clean the dust, which is time-consuming, laborious and inefficient. T...

AI Technical Summary

Problems solved by technology

When the fan starts to work, the vibration of the bearing part is very small, but as the running time increases, the dust in the fan will adhere to the impeller unevenly, gradually destroying the dynamic balance of the fan, and gradually increasing the vibration of the bearing. Once the vibration reaches the fan When the maximum allowable value is reached, the fan must be shut down for repair (remove dust accumulation, redo dynamic balance), because it is very dangerous at this time, and the user must not use it forcibly

The existing fan requires the staff to remove the fan and manually clean the dust, which is time-consuming, laborious, and inefficient. Therefore, there is no need for a fan that can be cleaned automatically to solve the above-mentioned problems
