[0001] This utility model relates to the field of chemical production equipment technology, specifically to a chemical safety feeding device. Background Technology
[0002] Chemical industry is an abbreviation for chemical process, chemical industry and chemical engineering. All technologies that use chemical methods to change the composition and structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemical products. In chemical production, various liquids and materials need to be placed in a reaction vessel to carry out chemical reactions in order to obtain chemical products. The device that transports the liquids or materials into the reaction vessel is called the feeding device.

[0034] Feeding tank 2, there are multiple feeding tanks 2, multiple feeding tanks 2 are arranged around the height adjustment mechanism, and a fixing ring 3 is sleeved on the outside of each feeding tank 2. The fixing ring 3 is connected to the height adjustment mechanism. A discharge pipe 4 is provided at the bottom of the feeding tank 2, and a discharge cylinder 5 is connected to the bottom of the discharge pipe 4.
[0035] The feeding tank 2 has a rotating shaft 6 nested inside. Multiple stirring rods 7 are fixed on both the left and right sides of the rotating shaft 6. The lower end of the rotating shaft 6 extends into the discharge pipe 4. The shaft body of the rotating shaft 6 inside the discharge pipe 4 is fixedly sleeved with a spiral blade 8.
