Description
Technical field
The utility model relates to air purification field, in particular to the air filter for motor.
Background technique
Motor be a kind of can be the machine that can be converted into mechanical energy of other form.Motor completes conversion process of energy by air amount, compression, igniting, acting.Therefore air amount completes transformation of energy for motor, process is absolutely necessary.The quality of motor air amount has very large effect for the performance of motor.If there is a large amount of sandstone slag dirt in the air sucking, can badly damaged motor, cause motor cisco unity malfunction, thereby incur loss through delay the duration, cause huge economic loss.In correlation technique, the intake grill place of motor is provided with single filter screen, is used for filtering the sandstone slag dirt in air amount, but this single filter screen can not effectively filter out the sandstone slag dirt in air amount; Especially when motor uses in the severe place of environment, owing to being mingled with a large amount of sandstone slag dirt in air, therefore this single filter screen can not filter out a large amount of sandstone slag dirt in air amount at all, thereby cause the damage of motor.
Model utility content
The purpose of this utility model is to provide air filter, to solve the above problems.
In embodiment of the present utility model, provide air filter, comprised ventilation duct, the first filter screen and the second filter screen; Ventilation duct is the hollow cavity of both ends open, and its one end is for being connected with the suction port of motor, and the other end is intake grill, and air enters ventilation duct from intake grill; The first filter screen and the second filter screen are set in parallel in ventilation duct along the direction away from intake grill successively; On the first filter screen, be provided with the first grid, be provided with the second grid on the second filter screen, the quantity of the second grid is more than or equal to the quantity of the first grid.
The air filter of the utility model above-described embodiment, by be provided with the first filter screen and the second filter screen in ventilation duct, and the second number of grid is more than or equal to the first number of grid.Therefore form staggered state between the first grid and the second grid.During use, ventilation duct is connected with the suction port of motor.Air enters after ventilation duct, and the double-layer filtering net that the sandstone slag dirt being clipped in air is staggered shape filters out, thus in the air that motor is sucked, do not contain sandstone slag dirt, thus extended the working life of motor, improved the usability of motor; The construction delay causing and the economic loss that causes have effectively been avoided due to breakdown in the motor.
Accompanying drawing explanation
Fig. 1 shows the structural representation of the air filter that the present embodiment provides.
