Description

Technical Field

[0001] The utility model relates to the technical field of refractory production, and specifically, to a dust collection device for a refractory vibrating screen. Background Art

[0002] Refractories are applied to various fields of the national economy such as iron and 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 operation and technological development of the above industries and play an irreplaceable important role in the development of high-temperature industrial production. According to the density and shape of the products, there are sintering methods, casting methods, and melt blowing methods, etc. The sintering method is to pre-burn part of the raw materials into clinker, crush and screen them, then mix them with raw materials according to a certain ratio, and go through forming, drying, and firing. After the raw materials are crushed and ground, they also need to be screened because the blank is graded with powders of different particle sizes, which can ensure the densest packing and obtain a dense blank.

[0003] After retrieval, it is found that the publication number is CN212493836U, and the name is a refractory screening device. This application points out that the existing refractory screening device uses vibration screening, with poor sealing performance, resulting in high noise and serious dust diffusion. By providing a suction fan and a dust collection bag at the top of the guide cylinder, it is beneficial to dust reduction and removal. However, the dust collection bag in this application has a limited capacity. When it is full, it needs to be cleaned by staff. During the cleaning process, the dust removal work cannot be carried out synchronously, resulting in a reduction in work efficiency and affecting the continuity of work, and further improvement can be made.

[0004] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model
