Description

Technical Field

[0001] The utility model relates to the technical field of refractory material processing, in particular to a batching dust removal mechanism for refractory material processing. Background Art

[0002] Refractory materials are a type of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material can resist high temperature without softening and melting under no load. However, defining it only by its refractoriness can no longer fully describe refractory materials, and 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high-temperature environment is called a refractory material. Refractory materials are used in various fields of the national economy, such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. They are essential basic materials to ensure the production and operation of the above-mentioned industries and the technological development. They play an irreplaceable and important role in the development of high-temperature industrial production. Among them, refractory materials need to be reasonably proportioned with the required raw materials.

[0003] After searching, the publication number CN218306978U discloses a batching dust removal mechanism for refractory material processing, including a batching bin, a motor is installed on the bottom surface of the batching bin, and the output end of the motor passes through the batching bin and is fixedly connected to a rotating rod, a spiral blade is provided on the rotating rod, and a connecting rod is provided below the spiral blade, and an auxiliary stirring blade is inclined at one end of the connecting rod. The utility model opens the induced draft fan while batching the refractory material, and through the coordinated use of the connecting pipe, the suction pipe and the dust suction port, the dust generated during batching can be effectively transported to the inside of the processing box, and then the water pump is turned on, and the water pump transports the external water source to the spray pipe through the water pipe through the pumping pipe, and then sprays water mist through the atomizing nozzle on the spray pipe, which can effectively reduce the dust and prevent the dust from spreading in the surrounding environment during batching, so that the device has a dust removal function, reduces the pollution of the surrounding environment caused by dust, and is conducive to improving the environmental protection of the device.

[0004] However, the refractory raw materials that have undergone the above-mentioned dust reduction treatment have been sprayed, which makes it impossible to incorporate them into the batching bin in the conventional mixing manner. In addition, since the "dust" flying in the batching stage is part of the refractory raw materials, it causes different degrees of deviation in the proportion of the various raw materials of the refractory raw materials, which greatly reduces the quality of the final refractory materials.

[0005] To this end, a dust removal mechanism for refractory material processing ingredients is proposed, which has the advantages of preventing raw material loss and maintaining the quality of refractory material ingredients, thereby solving the problems in the above-mentioned background technology.
