Its boiling point is 137-140°C, and its flash point is less than 28°C, making it flammable. Xylene is a low-toxic chemical substance and is irritating. High-concentration xylene vapor has a certain anesthetic effect on the human body. In chemical production, xylene is often used as a co-solvent or chemical reactant, and in the production and processing of xylene, it is necessary to use quantitative feeding equipment to feed the raw materials for the preparation of xylene.

[0035] The specific operations are as follows:

[0036] During the feeding process, the raw materials are injected into the mixing tank 1 through the injection pipe 201, the metering pump 202 and the guide tube 205. At this time, the metering pump 202 can measure the feeding content of the raw materials, thereby realizing the quantitative feeding of the raw materials.

On the other hand, the rotating shaft 302 drives the sub-gear 204 to rotate through the main gear 303, and at the same time, the universal joint formed by the ball seat 203 and the universal ball 206 can rotate the guide tube 205. During the rotation, the raw materials remaining on the inner wall of the guide tube 205 can be centrifugally thrown out through the through hole 207, which prevents the waste of raw materials on the one hand, and ensures the quantitative accuracy of feeding and the preparation effect of xylene on the other hand.
