Background technique

During the dust removal process of dust removal equipment involving oily dust and exhaust gas, such as filter cartridges and cloth bags, a lot of oily substances tend to accumulate on the walls. Therefore, it is necessary to spray powders such as talcum powder on the surface of environmental protection equipment such as filter cartridges and cloth bags or on the dust removal parts, in order to reduce the damage of oily substances to the dust removal equipment.

However, in the prior art, there is no equipment for spraying powder on the surface of filter cartridges, cloth bags, etc.; manual spraying is prone to problems of uneven spraying and easy blockage. Therefore, the prior art needs to be further studied.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a duster for dust removal equipment, which aims to solve the problems in the prior art that the spraying on the surface of the dust removal equipment is uneven and the spraying process is easy to block.

A secondary air flow channel is formed between the air chambers. One end of the pressurized pipe is connected to one end of the powder injection pipe, and the other end is connected to the pressurized air chamber. The other end of the powder injection pipe is a powder injection port. The air chamber and the powder injection port are correspondingly provided with air chamber connecting pipes.

The pressurized air chamber is set in a cone shape, the pressurized air chamber comprises an air chamber body and a bottom plate of one end of the air chamber body, and the other end of the air chamber body is an air chamber connecting pipe.

The powder injection pipe is welded on the bottom plate, the end of the powder injection port is arranged in the air chamber connecting pipe, and an air flow control valve is arranged on the pressurized pipe.

The powder spraying mechanism further includes a centrifugal fan, and a fan duct is arranged between the centrifugal fan and the pressurized air chamber, and the fan duct is arranged at the position of the air chamber body close to the bottom plate.

The feeding mechanism includes a feeding tank, a feeding motor arranged above the feeding tank, and a stirring mechanism connected with the feeding motor.

One end of the feeding tank is provided with a second powder feeding port, the other end is provided with a powder discharging port, and a connecting hose is provided between the powder discharging port and the first powder feeding port.

The stirring mechanism includes a stirring shaft, a first stirring rod, a second stirring rod and a third stirring rod arranged on the stirring shaft.

The beneficial effects of the present invention are:

1. The powder spraying mechanism of the present invention includes a pressurized air chamber, a powder injection pipe, and a pressurized pipe. The powder injection pipe is sleeved in the pressurized air chamber. The compressed air chamber is connected, and the centrifugal fan continuously supplies high-pressure air into the pressurized air chamber, and transmits the air flow to one end of the powder injection pipe through the pressurized air pipe. When blowing out the powder injection pipe, because the strong high-pressure airflow in the powder injection pipe forms a pressure difference with the outside world, the powder is blown out in a scattered shape to achieve the purpose of uniform spraying.

2. The pressurized air chamber of the present invention is set in a cone shape, and the fan pipe is installed near the bottom plate of the pressurized air chamber, and the powder injection pipe is sleeved in the pressurized air chamber, and there is a gap between the air chamber connecting pipe and the air chamber. Therefore, a secondary air flow channel is formed between the powder injection pipe and the pressurized air chamber. The powder injection pipe is a primary air flow channel. The powder is ejected to prevent the occurrence of clogging at the powder ejection port.

3. Another function of the conical pressurized air chamber of the present invention is to use the conical structure of the air chamber to eject the remaining pressurized air from the powder injection port in an umbrella-like manner, except for the auxiliary injection for the powder. In addition to the power, the chaotic airflow formed by the continuous refraction of the umbrella-shaped airflow in the pipeline can smash the columnar powder airflow into a uniform mist airflow and spray out. To ensure that the powder can intercept the free oil substances in the dust and exhaust gas with the largest coverage area after spraying. Improve the purification rate of exhaust gas and achieve the protection of dust removal equipment.
