Technical Field

[0001] The utility model belongs to the field of vibrating screen screen replacement, and in particular relates to an auxiliary device for vibrating screen screen replacement. Background Art

[0002] The scientific name of baking soda is sodium bicarbonate, also known as acid sodium carbonate. It is an acid salt and is used in food, medicine, film, tanning, mineral processing, metallurgy, fiber, rubber and other industries. It is generally used to make soda, ferment bread crumbs and steamed buns. It can also be used as a detergent and fire extinguishing agent. In the production process of baking soda, it is inevitable that there will be lumps or small particles in it, which will have a certain impact on the quality of the product, so a safety screening is required.

[0003] The baking soda production of our factory is generally between 100,000 tons and 150,000 tons, and the vibrating screen is used for continuous operation. As the use time increases, the screen of the vibrating screen is a wearable part and needs to be replaced in time after being damaged.
