Description

Technical field:

[0001] The utility model relates to the technical field of seedling boxes, in particular to a dust removal device for a calcium carbide furnace. Background technology:

[0002] Calcium carbide furnace is the main equipment for producing calcium carbide. In the calcium carbide furnace, the high temperature generated by the electric arc causes the charge to melt and react to produce calcium carbide. Since the reaction temperature is as high as over 2000℃, such a high temperature is difficult for general refractory materials to withstand. Therefore, the volume of the furnace must be larger than the reaction space. In other words, a layer of charge should be left between the reaction zone and the furnace lining to protect the furnace lining. During the production process of calcium carbide, the calcium carbide furnace will generate a lot of dust, which usually requires the use of a dust removal device for dust removal.

[0003] For example, Chinese patent application number "CN201922336634.5" discloses a dust removal device for calcium carbide furnace in calcium carbide production, including a housing component, a dust suction component and a filter component, wherein the housing component includes a water tank, the bottom of the water tank is fixedly connected to a drain pipe, and the dust suction component includes a dust suction pipe. The utility model reduces the dust concentration in calcium carbide production, improves the surrounding air quality, and improves the dust removal effect of the device by setting a dust suction device and a dust suppression mechanism.

[0004] After the product is improved, the dust removal device used for the calcium carbide furnace in the production of calcium carbide effectively solves the problem of dust by sucking the dust into the water tank and adsorbing the dust with clean water. The gas in the water tank is extracted by the exhaust fan, and the dust is filtered by the dust filter plate. However, when the dust filter plate works for a long time, a large amount of dust will adhere to its outer wall. If the dust filter plate is not cleaned, it is easy to cause the dust filter plate to become blocked, thereby affecting the effect of filtering dust. At the same time, when the device sucks the dust into the water tank, the dust needs to rely on its own weight to drop into the clean water for dust removal. This method is relatively inefficient and needs to be improved. Utility model content:
