Technical Field

[0001] The utility model relates to the technical field of refractory materials, in particular to a dust reduction device for refractory material production. Background Art

[0002] Refractory materials refer to a class of materials that can maintain physical and chemical stability under high-temperature environments. Common refractory materials include various refractory bricks, castables, ramming masses, etc. They are widely used in many industrial fields such as metallurgy, building materials, chemical industry, and electric power. For example, the linings of high-temperature equipment such as steelmaking furnaces, cement kilns, and glass furnaces play a crucial role in ensuring the safety and efficient operation of industrial production. Since dust is likely to occur in refractory material production workshops, dust removal devices are required to reduce dust in the production workshops. However, the existing dust reduction devices can only suck dust from one direction, resulting in low dust suction efficiency. Moreover, when discharging dust, dust is likely to accumulate and block at the valve. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a dust reduction device for refractory material production, which is used to solve the problems that the existing dust reduction device for refractory material production can only suck dust from one direction, resulting in low dust suction efficiency, and when discharging dust, dust is likely to accumulate and block at the valve.

[0004] To solve the above problems, the utility model provides a dust reduction device for refractory material production, including a dust removal box. An inclined drainage plate is fixedly arranged in the dust removal box. A hollow air distribution plate is fixedly arranged below the drainage plate. A plurality of connecting hoses are evenly and fixedly arranged at the bottom of the hollow air distribution plate. One end of each connecting hose away from the hollow air distribution plate is fixedly provided with a dust suction head. The dust suction head penetrates through the side wall of the dust removal box and extends outwards. A high-pressure air pump is fixedly arranged above the hollow air distribution plate. The air suction end of the high-pressure air pump is communicated with the inner cavity of the hollow air distribution plate. The air exhaust end of the high-pressure air pump penetrates through the drainage plate and extends upwards. An air guiding cover is fixedly arranged above the drainage plate. A spraying assembly is suspended above the air guiding cover. A sewage discharge pipe is fixedly arranged corresponding to one side of the dust removal box.

[0005] The dust reduction device for refractory material production provided by the utility model further has the following technical features:

[0006] Further, the inclination angle of the drainage plate is 15°.

[0007] Further, the number of the connecting hoses is at least 3.

[0008] Further, the air guiding cover successively includes a first conical section, a cylindrical section, and a second conical section from top to bottom.

[0009] Further, the spraying assembly includes a spraying disc suspended above the air guiding cover, a water pump and a water storage tank fixed to the outer wall of the dust removal box. The water pumping end of the water pump extends downward into the water storage tank, and the water discharging end of the water pump is communicated with the inner cavity of the spraying disc.

[0010] Further, a plurality of nozzles are fixedly arranged at intervals at the bottom of the spraying disc.

[0011] Further, a suspension rod is fixedly arranged at the top of the spraying disc. The top end of the suspension rod penetrates through the top wall of the dust removal box and is fixedly provided with a stop rod.

[0012] Further, a manual valve is fixedly arranged on the sewage discharge pipe.

[0013] The utility model has the following beneficial effects: When the high-pressure air pump is started, the dust can be pumped from different directions of the dust removal box through the plurality of dust suction heads, so as to expand the air suction range of the dust removal box. The dust-containing gas can be firstly gathered in the hollow air distribution disc through the plurality of connecting hoses, and then pumped into the air guiding cover together.
