Technical field:

The utility model relates to the technical field of environmental sanitation machinery and vehicles, in particular to a dust filtering device for medium and small road sweepers.

Background technique:

Traditional small and medium-sized road sweepers generally reduce dust by spraying water or filter bags and filter cartridges. The effect of simple water spray and dust reduction is generally not ideal, and the water consumption is relatively large, while the dust removal effect of filter bags and filter cartridges is relatively good, but Because of its high cost and large space, relatively cheap road sweepers seldom use filter cartridges to filter dust, but use water spray to reduce dust. When there is too much dust and garbage on the road surface, it is easy to raise dust and cause damage to the surrounding environment. Secondary pollution.

Utility model content:

In order to solve the above problems and overcome the deficiencies of the prior art, the utility model provides a dust removal filter device for small and medium-sized road sweepers;

The first technical problem to be solved is: traditional small and medium-sized road sweepers generally reduce dust by spraying water or through filter bags and filter cartridges. The effect of pure water spraying for dust reduction is generally not ideal, and the water consumption is relatively large;

The second technical problem to be solved is to use water spray alone to reduce dust. When there is too much dust and garbage on the road surface, it is easy to raise dust and cause secondary pollution to the surrounding environment.

The specific technical solution of the utility model for solving the above-mentioned technical problems is: the dust removal and filtering device of the small and medium-sized road sweeper is arranged on the vehicle frame of the road sweeper, including a dust removal box and a filter and dust removal structure arranged in the dust removal box. It is characterized in that: the dust removal box includes a dry chamber and a wet chamber; the filter and dust removal structure includes a suction duct and a dust cover arranged in the dry chamber and a filter of a rotating water curtain arranged in the wet chamber. unit;

The filter unit of the rotary water curtain includes a centrifugal fan, a disc-shaped bristle and a spray nozzle. The centrifugal fan is fixedly arranged at the air outlet of the wet chamber, and the rotating shaft of the centrifugal fan is extended in the wet chamber. The part is fixedly connected with the fixed turntable of the disc-shaped bristles through threaded connection; a spray nozzle with a spout facing the disc-shaped bristles is arranged below the disc-shaped bristles, and the spray nozzle is connected to the water pump through a water pipe.

Further, a vent is provided between the dry chamber and the wet chamber, and a filter is provided on the vent.

Further, the dust shield is made of stainless steel, the cross section is set as a trapezoidal hollow cylinder structure, one end of the dust shield is fixed to the vehicle frame, and the lower end surface of the dust shield is provided with an air outlet and a pipe fixed to the suction pipe. Inlet.

Further, the air outlet is arranged on the top of the wet chamber.

Further, the bristles of the disc-shaped bristles are fixedly connected to the fixed rotating disk by plugging.

The beneficial effects of the utility model are:

The utility model adopts the design of dry and wet double chambers. The dry chamber adopts the first-level gravity dust reduction and the second-level coarse filter dust reduction. The wet warehouse adopts a rotating water curtain filter device, aiming at solving the problem of simple spraying of small and medium-sized road sweepers. The defect that the effect of water dust reduction is not ideal;

The rotary water curtain filter device is at the air outlet of the box body. The main shaft of the fan is lengthened to install disc-shaped bristles, and a spray nozzle is installed under the bristles. When the fan rotates, the bristles are driven to rotate, and the spray nozzle sprays water mist to the high-speed rotating bristles. On the top, the water mist is driven by the bristles to form a water curtain, thereby blocking the dust in the dustbin and effectively filtering the dust;

With the dry and wet double chamber design, the solid debris is separated from the water for easy treatment and recycling, which avoids the sewage adhering to the debris and aggravating the difficulty of treatment.
