Description

Single machine pulse dust collector

technical field

The utility model relates to the field of powder preparation, in particular to a single-machine pulse dust collector.

Background technique

At present, when the powder is prepared, the powder is easily dispersed into the air, which causes the air to be polluted. Therefore, it is necessary to use a dust collector to remove the dust in the air. At present, the dust in the air is removed by filtering the air. The dust is then removed, but at present, when the dust in the air is removed, the filter bag needs to be cleaned or replaced for a period of time, resulting in reduced work efficiency. Therefore, it is particularly important to solve the problem that the filter bag needs to be cleaned and replaced after the dust collector works for a period of time, which affects the work efficiency.

SUMMARY OF THE INVENTION

In order to solve the above problems, the purpose of this utility model is to provide a single-machine pulse dust collector. The air enters the dust box through the air inlet, filters the large particles of dust through the isolation plate, and then filters the small particles through the filter bag, and passes through the exhaust port. discharge, and through the pulse controller and the electromagnetic pulse valve, the air pump generates a pulsed air flow and sprays it out through the air blowing nozzle, and the isolation plate and the filter bag are reversely impacted, so that the impurities attached to it fall into the dust collecting hopper, prolonging the operation time. It solves the problem that the filter bag needs to be cleaned and replaced after the dust collector works for a period of time, which affects the work efficiency.

The utility model provides a single-machine pulse dust collector, comprising a dust removal box, an air inlet is provided at the lower end of the dust removal box, an exhaust port is arranged at the upper part of the dust removal box, an isolation plate is arranged in the dust removal box, and the isolation plate A through hole is provided, and large particles of impurities are filtered through an isolation plate. A filter bag is arranged above the isolation plate, and the air is filtered twice through the filter bag. The upper end of the dust box is provided with an air blowing nozzle. The top of the dust box is provided with an air pump, the air pump is connected to the air blowing nozzle through an air pipe, and a pulse controller and an electromagnetic pulse valve are arranged on the air pump. The nozzle sprays out, and a dust collecting hopper is arranged at the lower end of the dust box.

A further improvement is that a cleaning brush is arranged on one side of the lower end of the isolation plate, a telescopic moving cylinder is arranged outside the dust box, and the cleaning brush is driven by the telescopic moving cylinder to brush the lower end of the isolation plate.

A further improvement is that: the filter bag is driven by the telescopic cylinders at both ends to move up and down the filter bag, and the dust on the filter bag falls off by inertia.

A further improvement is that: a control PLC is arranged beside the dust removal box, and the action control of the air pump, the pulse controller, the electromagnetic pulse valve, the telescopic mobile cylinder and the telescopic cylinder is performed by the control PLC.

The beneficial effects of the utility model are as follows: the air enters the dust box through the air inlet, filters the large particles of dust through the isolation plate, and then filters the small particles through the filter bag, and is discharged through the exhaust port, and passes through the pulse controller and the electromagnetic pulse valve. The air pump generates a pulsed airflow and sprays it through the blowing nozzle, and reversely impacts the isolation plate and the filter bag, so that the impurities attached to it fall into the dust collecting hopper, prolonging the time of single use and improving work efficiency.
