technical field

The utility model relates to the technical field of dust removal equipment, in particular to a numerical control pulse blowing and dust removal system and an urban road dust collection vehicle.

Background technique

Most of the existing dust collectors rely on mechanically driving the fan impeller to rotate, and the rotation of the fan impeller causes the air to be discharged from the vacuum cleaner at high speed, which causes a pressure difference between the inside of the vacuum cleaner and the environment; under the action of the pressure difference, the air in the environment, Dust and so on are sucked into the vacuum cleaner through the gap between the dust collection cover and the surface of the object. After being filtered by the dust filter in the vacuum cleaner, the filtered air is discharged out of the vacuum cleaner, and the dust collection work is completed.

At the same time, the research and development personnel found that when the vacuum cleaner is working, the greater the pressure difference between the interior of the vacuum cleaner and the environment, the better the dust collection effect, and the pressure difference between the interior of the vacuum cleaner and the environment must be increased during operation.

One is that in order to increase the pressure difference between the interior of the vacuum cleaner and the environment when the existing vacuum cleaner is working, it is necessary to increase the power of the vacuum cleaner fan, but increasing the power of the fan also increases the energy consumption of the vacuum cleaner.

The 2nd, prior art has strict requirement on the gap between the dust collection cover and the surface of the object, if the gap is too small, the air volume passing through the dust filter is small, the dust intake is insufficient, and the dust collection efficiency is low; but if, the dust collection cover and The gap on the surface of the object is too large, the pressure difference is small, the wind speed is small, the effect of disturbing the dust is poor, and the dust collection efficiency is low.

The third is that in the prior art, the pressure difference between the inside and the outside of the dust collection hood is large, and the dust collection hood needs a pressure-bearing hardware structure. In order to prevent the dust collection hood from colliding, there are strict requirements on the flatness of the surface of the object.

The 4th, prior art is subjected to the restriction of high wind speed turbulent dust raising efficiency, and air volume is less, and dust inhalation is insufficient, and work efficiency is low.

The 5th, prior art discharges through the air after the dust filter filter in the vacuum cleaner, because the aperture of filter can not be too small, contains small particle dust in the discharge air, causes secondary pollution discharge.

To sum up, if it is necessary to overcome the above-mentioned technical defects of the vacuum cleaner in the traditional technology, it is necessary to revolutionize the structure of the traditional vacuum cleaner; therefore, how to overcome the above-mentioned technical defects of the vacuum cleaner in the traditional technology is a technical problem urgently needed to be solved by those skilled in the art.
