Air-intake and filter device of motor

Abstract

The invention relates to a filter device installed at the air inlet of a self-ventilation motor, and in particular relates to an air-intake and filter device of a motor. The air-intake and filter device of the motor comprises a shell taking the shape of an arc, wherein one side of the shell is provided with an air inlet, the lower part of the shell is provided with an air outlet, and a protection cover is arranged on the air inlet; a dust collection groove with an open upper part is arranged in the shell close to the air outlet, and the dust collection groove is separated from the air outlet through a partition fixed among the inner wall of the shell, the dust collection groove and the air outlet; a lower air deflector is arranged above the partition, the air inlet of the shell stretches inwards to be provided with an upper air deflector which takes the shape of an arc and fits with the arc-shaped shell, an air intake channel is formed between the upper air deflector and the inner wall of the shell, and the lower end of the upper air deflector is positioned above the lower air deflector and has a gap with the same; a dust removal opening is arranged on the dust collection groove. The air-intake and filter device of the motor is simple in structure, small in wind resistance, easy to maintain, convenient to maintain and greatly saved in cleaning and maintaining costs, and can be widely applicable to filtering dust of the self-ventilation motor.

Description

technical field [0001] The invention relates to a dust filter device assembled at the air inlet of a self-ventilating motor, in particular to a motor air inlet dust filter device. Background technique [0002] At present, self-ventilated motors are favored by motor users for their advantages of simple structure, easy maintenance, low noise and small space occupation, and have been widely used. However, tiny particles in the cooling air entering the motor will cause damage to the winding insulation of the motor. Damage will affect the life of the motor. Therefore, the dust removal structure and device of the self-ventilated motor, as well as its dust removal effect, have attracted widespread attention. Most of the existing self-ventilating motors rely on the air inlet to install a dust cover to meet the use requirements of clean cooling air. The existing structure of the dust removal cover is to arrange several layers of filter screens at the air inlet, and the middle of the...
