Description

An environmental protection dust removal device for a dry road sweeper

technical field

The utility model belongs to the field of environmental sanitation mechanical equipment, in particular to an environmental sanitation dust removal device for a dry-type road sweeper in the environmental sanitation industry.

Background technique

Now the problem of environmental pollution is becoming more and more serious, so in order to effectively reduce pollution, the government and relevant units have made great efforts. In the northern region, urban roads have a large amount of dust and dust, and most of them use dry sweepers to remove dust. At present, when the dry-type road sweeper unloads dust, it is easy to cause secondary pollution of dust, because there is no effective dust collection and purification device around the dry-type road sweeper.

Moreover, after each cleaning operation, in order to effectively remove the dust accumulated on the filter bag and improve the dust suppression effect of the cleaning operation again, the sanitation staff often drive the road sweeper into the workshop of the environmental sanitation brigade, and put the road sweeper The outer door of the filter is opened, and the high-voltage pulse back-blowing and dust-cleaning operation is carried out, which causes the dust in the workshop to diffuse and escape, and also causes serious pollution to the working environment and the surrounding environment.

Therefore, it is very necessary to develop a kind of high-efficiency dedusting and dust removal device supporting the dry road sweeper.

Utility model content

The technical problem to be solved by the utility model is to provide an environment-friendly dust removal device for a dry road sweeper with fast dust removal speed, good dust removal effect, convenient operation and maintenance, and low cost of use, which can prevent secondary pollution from flying dust.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions to achieve: a dust suppression device for dry-type road sweeper unloading and filter dust removal, the key technology of which is: it includes the collection of road sweeper unloading The dust suppression hood, the dust collector connected with the middle part of the dust suppression hood, which can absorb dusty fine materials, the induced draft fan connected with the dust collector, the air duct connected with the induced fan, and the lower part of the dust suppression hood and its discharge hopper The connected conveying auger, the elevator connected to the discharge end of the auger, and the wet material box connected to the discharge port of the elevator, the dust collector communicates with the discharge hopper through the dust fall pipe at the lower part.

The lower part of the cartridge filter of the dry road sweeper communicates with the dust collector through a tee.

The upper part of the conveying auger is provided with a dust-humidifying nozzle, and the nozzle communicates with a water tank with a water pump.

Preferably, the dust collector adopts a bag dust removal device.

The beneficial effects produced by adopting the above-mentioned technical scheme are:

1. The utility model is equipped with a dust suppression cover, and the dry road sweeper is directly poured in to unload the dust, the dust is sucked into the dust collector by the induced draft fan, and the heavy dust and miscellaneous materials enter the falling hopper through the lower opening, which can prevent Secondary pollution during ash unloading; there is a screen in the falling hopper, and the distance between the screens is relatively large. The machine transports to the wet material box.

2. The utility model is equipped with a nozzle and a matching water tank, which can humidify the dust and prevent it from flying and polluting the environment, and the treated dust falls into the wet material box, which can realize dust-free storage, loading, and transportation of fine materials.

3. According to the characteristics of the ash unloading operation of the dry sweeper, the utility model adopts the "collection + separation + dust suction + humidification" process, which effectively controls the primary and secondary dust pollution during the ash unloading and cleaning process, which is conducive to popularization and application.
