Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a conveyor belt mist dust reduction device for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of sand and stone aggregates bonded together by cementitious materials. During the concrete production process, the required sand and stone aggregates are often transported a short distance to the mixing bin via conveyor belts.

[0003] However, in the process of transporting sand and stone aggregates by conveyor belts, a large amount of dust will inevitably appear. In order to reduce the dust pollution caused by the sand and stone aggregates during the transportation process, a connecting cover is usually installed on the top surface of the base connected to the conveyor belt, and then a dust removal pipe and a nozzle are arranged inside the connecting cover. A water source is then introduced into the dust removal pipe, and water is sprayed out under the action of the nozzle to achieve the purpose of dust reduction.

[0004] The above structure is carried out inside the connecting cover during the dust reduction process, so that the pollutants generated by the water source spraying the dust will fall on the transported raw materials, and then fall into the concrete mixing bin along with the transportation of the raw materials, thus affecting the quality requirements for concrete processing. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the pollutants generated in the dust reduction process cannot be separated from the raw materials being transported, which affects the requirements for the quality of concrete processing.

[0007] A support frame is provided on the top surface of the installation cover near the dust exhaust port, and a spraying device is provided on the support frame. A guide cover 1 is arranged around the end surface of the installation cover corresponding to the air inlet, and an outlet pipe which penetrates the interior of the guide cover 1 is passed through the guide cover 1.

[0008] Furthermore, the spraying device includes a dust removal pipe and an atomizing nozzle. The support frame is an inverted L-shaped structure and an arc groove is opened on the bottom surface of the horizontal end along its length direction. A dust removal pipe matching with it is arranged in the arc groove. A plurality of atomizing nozzles intersecting with it are arranged at equal distances on the dust removal pipe along its axial direction, and a conveying pipe intersecting with the dust removal pipe is also arranged on the support frame.

[0009] Furthermore, both ends of the dust removal pipe are connected to the bottom surface of the support frame through arc seats.

[0010] Furthermore, a second air guide cover is provided on the end surface of the mounting cover corresponding to the dust exhaust port.

[0011] Furthermore, sealing plates are respectively provided at the left and right ends of the connection cover, and there is a distance between the bottom surface of the sealing plate and the top surface of the conveyor belt.

[0012] The advantages of the utility model compared with the existing technology are:

Dust generated in the raw materials during transportation will move upward into the mounting cover 5 as the dust increases due to its light weight. A dust outlet 6 is provided on one end surface of the horizontal end of the mounting cover 5, and an air inlet 13 is provided on the other end surface. A guide cover 7 is also provided on the end surface of the mounting cover 5 corresponding to the dust outlet 6;
