Abstract

As cities develop, the proportion of small particle contaminants and other contaminants adhering to the ground increases. Municipal waste sweeping has become increasingly difficult to solve this problem. The design refers to a dust collector and an air purifier, and the device is a mobile near-ground air purification device which comprises a blowing part, a dust collection part, a filtering part and a rack part. When the dust collector is used, the air blowing part and the dust collection part firstly start to work, the air blowing part blows small particles on the ground, and the dust collection part sucks the small particles blown by the air blowing part into the filter box. The water spray device atomizes water in the water tank, and the water is sprayed to the polluted part of the filter box through the water spray nozzle, so that the water spray is mixed with unfiltered air and particles sucked by the dust suction part. The mixed air and particles pass through the filter cloth, the particles are remained on the filter cloth, and the fresh air enters the atmosphere.

Description

Mobile near-ground air purification device

technical field

The invention relates to a mobile near-ground air purification device which uses physical methods to clean fine solid and particle garbage on the ground and in the near-ground space.

Background technique

With the development of cities, the pollutants on urban roads have become diversified. In addition to the large-particle pollutants that can be cleaned, the proportion of small-particle pollutants and other pollutants that adhere to the ground has increased. Urban garbage cleaning has gradually become difficult to solve this problem. On the indoor ground, people usually mop the floor with a mop, or clean the ground with a vacuum cleaner, but the outdoor ground cannot implement this type of cleaning work due to its large area. This design refers to vacuum cleaners and air purifiers. It is a mobile near-ground air purification device including four parts: blowing part, dust suction part, filter part and rack part.

Contents of the invention

This design is a mobile near-ground air purification device including four parts: blower part, dust suction part, filter part and rack part.

When this device is used, it is installed on a power tractor or on the chassis of a special cleaning vehicle.

The blowing part is composed of a positive pressure fan.

The air inlet of the blowing part communicates with the outside air, and the air jet is close to the ground to blow up the small particles on the ground.

The dust collection part is composed of a negative pressure fan.

The air inlet of the dust suction part is installed opposite to the air jet of the blast part, so that the small particles blown up by the blast part can easily enter the dust suction port.

The filtering part is composed of a water mist spraying device, a filter cloth updating device and a filter box body.

The water mist spraying device comprises a water tank, an atomizing device and a water mist nozzle. Atomization device chooses one of pressurized nebulizer or ultrasonic nebulizer. The water mist spraying device sprays the water in the water tank into the polluted part of the filter box, so that the water mist is mixed with the unfiltered air and particles inhaled by the dust collection part.

The filter cloth updating device is composed of a filter cloth passive roller and a driving roller. The driving roller is driven by a reduction motor to rotate. A new filter cloth is wound on the passive roller, and one end of the main filter cloth is fixed by the driving roller. When the filter cloth needs to be updated, the driving roller rotates, so that the filter cloth is gradually wound on the driving roller, and the new filter cloth on the passive roller is supported between the driving roller and the passive roller again.

The active roller, the passive roller and the filter cloth between them divide the filter box into a polluted part and a clean part.

The air outlet of the dust collection part communicates with the polluted part of the filter box.

The cleaning part of the filter box body communicates with the outside atmosphere.

The frame part includes a frame body and support wheels. The blower part, the dust suction part and the filter part are fixedly installed on the frame body.

Among them, 1 is the frame body, 2 is the positive pressure fan, 3 is the negative pressure fan, 4 is the filter box, 5 is the passive roller, 6 is the water mist nozzle, 7 is the atomization device, 8 is the geared motor, 9 is the driving roller, and 10 is the Water tank, 11 is support wheels.

detailed description

Manufacture and process according to the sketch, select and install each part. Fill the tank with water.

During use, the blower part and the dust suction part start to work at first, the blower part blows up the small particles on the ground, and the dust suction part sucks the small particles blown up by the blower part into the filter box. The water mist spraying device atomizes the water in the water tank and sprays it on the polluted part of the filter box through the water mist nozzle, so that the water mist is mixed with the unfiltered air and particles inhaled by the dust collection part. The mixed air and particles pass through the filter cloth, the particles remain on the filter cloth, and fresh air enters the atmosphere.

After working for a period of time, the deceleration motor rotates to update the filter cloth, and other parts continue to work, and the cycle is repeated.
