[0002] Sulfur is widely used in sulfuric acid production, rubber vulcanization, pesticide manufacturing and other fields as important chemical raw materials. In the process of sulfur production, molten sulfur often contains ore residues, ash, metal particles and other solid impurities. These impurities can reduce the purity of sulfur and affect its subsequent application. Therefore, filtration is a key link in sulfur refining. Traditional filter devices mostly use single-stage filtration, which has low filtration efficiency, insufficient precision, is prone to blockage, and is difficult to maintain. In addition, it is not easy to adapt to different types and concentrations of impurities, and has poor applicability. Therefore, it is necessary to develop a filter device for sulfur refining that can improve filtration precision, ensure filtration efficiency, is easy to maintain and has strong applicability.

[0009] This utility model has the following advantages compared with the prior art:
[0010] This invention utilizes a series of staggered filter plates with progressively increasing mesh sizes to achieve multi-stage filtration of impurities of different sizes in materials, thus improving filtration accuracy. A jacket ensures the stability of the material within the device, preventing solidification that could affect filtration efficiency. Simultaneously, an air pressurization pump maintains a fixed pressure inside the chamber, ensuring that filtration efficiency meets requirements under varying conditions. The inclined filter plates prevent clogging of a single filter layer from affecting subsequent stages and reducing filtration efficiency. The detachable filter plates facilitate replacement and maintenance in case of clogging and ensure applicability to various materials. Attached Figure Description
