Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a material screening device for chemical industry. Background Art

[0002] Chemical materials are an essential component of the chemical production process. These materials are diverse and come in a wide variety of forms, from common solids and liquids to gases. Solid materials include various ores, powdered catalysts, and fillers. For example, phosphate rock is a key raw material in fertilizer production.

[0003] Traditional chemical material screening devices often have some significant issues in practical applications. First, material discharge difficulty is a prominent issue. After screening, materials tend to accumulate at the discharge port. This accumulation not only hinders the smooth discharge of subsequent materials, but also takes up space and affects the cleanliness of the production site. Over time, the accumulated materials may undergo adverse changes such as agglomeration, further increasing the difficulty of material discharge and significantly affecting production efficiency. Secondly, during the discharge process, the material may become blocked. The blocked material may accumulate inside the device, causing damage to the equipment and increasing maintenance costs.
