A dust processing device for transporting machine-made sand, comprising a dust removal box, a water washing chamber is arranged in the dust removal box, a sprinkler head is arranged on the top of the water washing chamber, and flowing water plates are alternately and fixedly installed in the water washing chamber, and the flowing water The bottom of the washing chamber is provided with a sedimentation chamber and a circulation chamber, the sedimentation chamber and the lower half of the circulation chamber are separated, and a filter plate is arranged between the sedimentation chamber and the circulation chamber. For filtering, the end of the flow plate at the bottom is inserted into the sedimentation chamber and is lower than the lowest water level in the water washing chamber.

The dust removal box is arranged on one side of the discharge port, and a conveyor belt is located below the discharge port. A blocking frame is arranged between the discharge port and the conveyor belt. The interior of the blocking frame is communicated with the washing chamber, and the blocking frame is connected to the A screen with an inclined surface facing downward is arranged at the connection of the washing chamber, a receiving plate is fixedly installed under the screen, and a fan is arranged on the side of the shielding frame away from the dust box.

A water pump is arranged at the bottom of the circulation cavity, and a water guide pipe is connected to the outside of the water pump, and the water guide pipe is connected to the shower head.

The bottom of the sedimentation chamber is provided with a sewage outlet.

To sum up, the beneficial effects of the present utility model compared with the prior art are: the device is arranged at the position where the stone material falls from the discharge port to the conveyor belt, the shielding frame closes the surrounding of the falling point, leaving only one opening in the conveying direction of the conveyor belt , There is a fan at this opening, which can blow the sand and dust generated here into the dust box to avoid leakage. After entering the dust box, the sand and dust merge into the sprayed water, and continue to stay along the stepped flow plate, passing by on the way. Some solids are left until it flows into the sedimentation chamber for precipitation. The relatively clear water in the upper layer of the sedimentation chamber flows into the circulation chamber, and then is pumped to the top by the water pump for spraying, which not only solves the problem of dust pollution, but also saves money. water resources.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

A dust processing device for transporting machine-made sand includes a dust removal box 10, a water washing chamber 11 is arranged in the dust removal box 10, and a sprinkler head 12 is arranged on the top of the water washing chamber 11, and the sprinkler head 12 can prevent the entry of the dust. The sand and dust gas in the washing chamber 11 is sprayed, and a plurality of flow plates 13 are alternately and fixedly installed in the washing chamber 11. The flow plate 13 is provided with 26, and the sand and dust are mixed with the spray head 12 and sprayed out. After the water is washed, it flows along the flow plate 13, and the 26 can leave some sediments when the muddy water flows through.
