Automatic dust removal dust collector

Abstract

The invention discloses an automatic dust removal dust collector, which comprises universal wheels, directional wheels, a cart bracket, a fan, a fan air outlet tube, an AC traction electromagnet, an external dust collection pipeline, a dust collection barrel and fan connecting pipeline, a fan blow-back acting pipe, a fan blow-back acting pipe one-way valve, an air outlet silencing pipe, an air outlet silencing pipe one-way valve, a hand push rod, a fan airflow reversing mechanism, an electric appliance switch box, a three-phase current aviation plug, a box body, a dust collection barrel and a fan air inlet pipe. According to the dust collector provided by the invention, on the basis of the principle of airflow reverse circulation which is caused through back-blowing by virtue of the fan, a purpose of automatically cleaning a filter can be achieved; the dust collector is compact in structural design and convenient, and the dust collector, which is not externally connected to a blow-back filter element cleaning mechanism, is low in cost; by arranging the air outlet silencing pipe, noise, which is generated from the dust collector during working, can be reduced, and the dust collector is conducive to protection of a working environment; and by arranging the one-way valves, crossed airflow is prevented when the dust collector works under two states, so that stable working states are guaranteed.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to an automatic dust-cleaning vacuum cleaner. Background technique [0002] At present, industrial vacuum cleaners are devices that use vacuum to generate suction to inhale air, make the air flow through various filters, and filter foreign objects in the air. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming an instantaneous vacuum in the vacuum cleaner, and forming a relativ...

[0008] 3. Pulse blowback to clean dust, using external compressed air to release instantaneously through the solenoid valve to achieve the effect of cleaning dust. The effect is better than the above two effects, but external compressed air is necessary, and it consumes more air. If the vacuum cleaner needs to move , it is very inconvenient to add a live line to the trachea, and it cannot be used in some places without compressed air
