Description

Dust purification device

technical field

The utility model relates to a dust purification device for preventing and controlling environmental pollution.

Background technique

The dust removal system in the chili food processing industry generally uses an induced draft fan to guide the dust to the filter cover, and then collects it in a cloth dust bag for secondary filtration. The main defect is that the dust will seep into the outside through the dust bag and cause pollution; The filter cover and vacuum bag must be cleaned regularly, which is inconvenient to use, and the dumping and disposal of dust can easily cause dust to fly and cause secondary pollution.

In the prior art, the spray purification technology is also adopted. The dust is adsorbed on the water droplets by spraying and spraying water and merged into a water flow, which enters the purification pool for precipitation through the diversion pipe and the filter screen. This technology effectively avoids cleaning the dust collection bag. The main defect is that the silt formed by dust and water is easy to adhere and accumulate on the inner wall of the diversion pipe and the filter screen, the filter screen is easy to block, and the cleaning frequency is high. Only tools can be used to clean the inner wall, which is time-consuming and labor-intensive; in addition, the purification tank takes a long time to settle, and because the fine particles of dust generated during the processing of peppers are light in weight and difficult to dissolve in water, they cannot be completely absorbed by water droplets, and some of the unadsorbed dust will be With the gas discharged into the atmosphere or floating on the water surface of the purification pool without sinking, it will fly again in the wind, and the purification is still not complete.

Utility model content

In order to solve the above problems, the utility model provides a dust purification device.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows.

A dust purification device, including a blower, a purification tank, a water pipe, and a spray nozzle. There is an exhaust pipe on the top of the dust cylinder, and the exhaust pipe extends to the bottom of the purification pool.

Spray nozzles are evenly distributed above the aforementioned mixing chamber, and the spray nozzles are connected to the purification pool through water meters, water pipes, and water pumps in sequence.

There are helical blades in the aforementioned mixing chamber, and the central axis of the helical blades is connected to the motor through a belt.

There is a discharge port at the bottom of the end of the stirring chamber, and a removable baffle is provided between the discharge port and the stirring chamber.

With the above technical solution, since the air outlet pipe of the blower is tangent to the inner wall of the dust collection box, the airflow in the dust collection box carries the dust to make a rotating motion, and the dust particles are separated from the air flow under the action of centrifugal force and thrown in the dust collection box On the inner wall, the airflow enters the water in the purification tank through the exhaust pipe, the water filters the residual dust in the airflow, and the purified airflow is discharged into the atmosphere with the air bubbles; at the same time, the dust on the inner wall of the dust collection box settles to the dust collection chamber due to the action of gravity. The feeding box at the bottom of the barrel enters the mixing chamber; the spiral blade divides the mixing chamber into multiple small chambers, and the multiple chambers isolate the dust in different spaces, and the amount of dust in a single chamber becomes smaller and is easier to be sprayed The nozzle is fully sprayed. After spraying, the dust is stirred under the rotation of the spiral blade and moves to the end of the mixing chamber. The dust is finally stirred into a mud ball. When the baffle is pulled away, the mud ball falls into the discharge port.

Through the water meter, the amount of water sprayed into the mixing chamber can be observed, so that the water pump can be turned on or off in time to prevent the dust from being stirred and diluted into mud. Pulling and inserting the baffle can control the dust mixing time, and then pull out the baffle after the stirring is complete.

The swirling airflow in the dust collector can realize the self-cleaning of the inner wall of the dust collector; the spray nozzle in the mixing chamber can also realize simple self-cleaning under the action of water pressure, even if there is a small amount of dirt, the spray nozzle will not be blocked; the spiral The power transmission of the blade is located outside the mixing chamber, so the inside of the mixing chamber will not be cleaned and the normal operation of the spiral blade will not be affected.

The dust can be completely purified through the centrifugal dedusting and submersible filtration of the dust collector; the dust is fused with water in the mixing chamber to form a mud mass, which reduces the settling time of the purification tank. In the whole collection and purification process, there is basically no physical exertion of personnel, and the utility model does not need to clean internal components.

The utility model is simple and convenient to operate, saves time and labor, does not need to clean the internal components frequently, not only cleans the dust thoroughly, but also can obviously reduce the cleaning time.
