Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a quantitative safety mechanism for feeding. Background Technique

[0002] Triethylaluminum is an organic compound, and its main uses include being used as a catalyst, initiator, rocket fuel, and for gas aluminizing, etc. Triethylaluminum can dissolve in benzene and can be miscible with saturated hydrocarbons. It is extremely sensitive to oxygen, can spontaneously combust in air, and may even explode. It will decompose violently when encountering water, generating aluminum hydroxide and alkane gas, and may cause combustion. When operating triethylaluminum, it is necessary to be tightly sealed, provide sufficient local exhaust ventilation and overall ventilation. Operators should wear appropriate protective clothing, gloves and goggles. Smoking is strictly prohibited at the work site, and explosion-proof ventilation systems and equipment should be used.

[0003] When using triethylaluminum, it is usually necessary to determine the usage amount of triethylaluminum according to the amount of raw materials in the reaction kettle. The usage amount of triethylaluminum should be accurate to avoid excessive or insufficient use. Therefore, a quantitative safety mechanism is often set before the reaction kettle to control the usage amount of triethylaluminum.

[0004] However, for common quantitative safety mechanisms, the amount of triethylaluminum used each time is fixed. When the amount of raw materials used is different, quantitative safety mechanisms with different capacities need to be used, resulting in an increase in production costs. Replacing the quantitative safety mechanism requires a lot of time. In view of this, this application proposes a quantitative safety mechanism for feeding. Content of the Utility Model
