Description

Technical Field

[0001] The utility model relates to the technical field of gypsum powder sieving machines, in particular to a new type of gypsum powder sieving machine. Background Art

[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate. Gypsum is a widely used industrial material and building material. The gypsum sifter mainly uses physical principles such as vibration or airflow to sieve gypsum powder. The gypsum sifter is used for gypsum processing operations.

[0003] A Chinese patent discloses a gypsum powder raw material screening machine (authorization announcement number CN220406284U). The patent technology uses a dustproof mechanism to drive the rotating rod to rotate through a motor, thereby driving the transmission wheel to rotate, and then drives the cover plate to move forward through a connecting belt until the cover plate completely covers the material opening, shielding the feeding trough to prevent the gypsum powder from generating a large amount of smoke and dust during screening, which pollutes the production environment. However, the above-mentioned gypsum powder raw material screening machine can only perform dustproof operations during the screening process. The dust generated during the feeding process is scattered, affecting the cleanliness of the working area. The fineness of the screened gypsum powder is large, and the gypsum powder accumulates in the box, which will affect the smoothness of the discharge and the processing efficiency of the gypsum powder. Therefore, those skilled in the art provide a new gypsum powder screening machine to solve the problems raised in the above-mentioned background technology. Utility Model Content
