Description

Technical Field

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

[0002] Calcium aluminate powder is a chemical raw material commonly used in water treatment and flocculant preparation. It mainly contains calcium dialuminate and calcium monoaluminate. It is an off-white powder in appearance, slightly soluble in water and its aqueous solution is alkaline. It has a high reactivity with inorganic strong acids and can react quickly at room temperature. When heated to a certain temperature, it will begin to dehydrate and decompose, releasing crystal water. It is an important raw material for the manufacture of water treatment flocculants, mainly used in the preparation of polyaluminum chloride, and is widely used in the purification process of drinking water and wastewater treatment.

[0003] The process of producing calcium aluminate powder includes reacting aluminum ore with calcium oxide, and then calcining, grinding and other steps are required to obtain the final product. In the process of preparing calcium aluminate powder, since it needs to be ground into powder, it is necessary to set up a dust removal device around the device to avoid air pollution. The traditional dust removal method absorbs the gas generated in the production process and then adsorbs it. This method is simple and reliable, but it is difficult to clean the dust reduction device after the adsorption is completed. Therefore, a dust reduction device for calcium aluminate powder production is proposed. After traditional adsorption dust reduction, the overall structure can be disassembled for easy later cleaning to avoid the dust reduction efficiency of the dust reduction device being reduced after repeated use, thereby causing air pollution.

[0005] In order to achieve the above-mentioned purposes of high flexibility and simple disassembly, the utility model provides the following technical solutions: a dust reduction device for calcium aluminate powder production, comprising a box body, an air intake assembly arranged on the side wall of the box body, a dust removal assembly movably connected to the side of the air intake assembly, a cleaning assembly arranged at the bottom of the dust removal assembly, an air suction assembly movably connected to the side of the dust removal assembly, an exhaust assembly arranged on the side of the air suction assembly, and a stabilizing assembly arranged on the outside of the box body.

[0008] Furthermore, the cavity inside the dust removal seat is connected to the cavity of the air pipeline, the bottom of the limit seat is embedded in the cavity inside the dust removal seat and is fixed to the dust removal seat by a snap, the surface of the adsorption mesh plate is provided with air holes, and the inner center position of the sealing plate is provided with an air channel for use with the air pipeline, and the side of the sealing plate and the inner wall of the dust removal seat are slidably connected.

[0009] Furthermore, the cleaning assembly includes a storage box movably connected to the bottom wall of the box body, a plurality of fixing seats fixedly installed on the bottom wall of the storage box, a plurality of cleaning rods movably connected to the top of the fixing seats, and a cleaning brush fixedly installed on the top of the cleaning rods.

[0014] Compared with the prior art, the utility model provides a dust suppression device for calcium aluminate powder production, which has the following beneficial effects:

[0015] 1. The dust reduction device for calcium aluminate powder production uses an air suction box and a ventilation fan to suck gas into the device through the air intake pipe and the air supply pipeline in the air intake assembly. The dust removal seat and the air supply pipeline are internally connected, so that the gas can pass through the adsorption mesh plate fixed by the internal limit seat of the dust removal seat, so that the adsorption mesh plate adsorbs the flowing air, and then continues to pass through the air permeable channel arranged inside the sealing plate to smoothly ventilate the air supply pipeline to the adsorption position of the next layer. At the same time, the sliding connection between the side of the sealing plate and the inner side wall of the dust removal seat can prevent the gas from overflowing from the side without adsorption.

[0016] 2. The dust reduction device for calcium aluminate powder production disconnects the air intake pipe and the air delivery pipeline by rotating the air intake pipe, and then removes the connection between the air guide flange and the exhaust pipeline. When the limit seat is removed, the cleaning rod extends to the inside of the dust removal seat, so that the cleaning rod on the top of the fixed seat cooperates with the cleaning brush to clean the particles adsorbed on the side of the adsorption mesh plate and enter the storage box through the slot on the top of the storage box, thereby achieving preliminary cleaning of the side wall of the adsorption mesh plate. The adsorption mesh plate can then be completely removed and replaced, thereby solving the problem that the dust reduction efficiency of the dust reduction device may be reduced after repeated use, thereby causing air pollution.
