Description
Technical Field
[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle with a stratification function. Background Art
[0002] Generally speaking, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized; reaction kettles are widely used in petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. Most of the solutions after the reaction are stratified, and it is necessary to extract samples of different solutions for detection.
[0003] At present, for the existing reaction kettles with a stratification function, the sampling pipe is set at a fixed height. However, the amount of solution reacted each time in the reaction kettle is different, so the height of the solution stratification will also be different each time. When sampling through the sampling pipe, the sampling position is likely to deviate. For other reaction kettles with a stratification function and a height adjustment function, the sampling mechanism is located inside the reaction kettle, and it is not convenient for personnel to judge the position of the sampling mechanism and the height of the solution stratification, so there may also be a problem that the sampling position deviates.
[0004] Therefore, aiming at the problem that for the above-mentioned reaction kettles with a stratification function, the amount of solution reacted each time is different and the height of the solution stratification is different, resulting in deviation of the sampling position, a reaction kettle with a stratification function can be designed. By setting a suction pump, a liquid suction pipe, a connecting hose, a mounting plate, a multi-stage push rod, a density sensor, a liquid outlet pipe, and a PLC controller, the multi-stage push rod can adjust the height of the connecting hose, and the density sensor can automatically monitor the position of the connecting hose in the solution. The two cooperate with each other, so as to automatically adjust the sampling height and avoid the problem of deviation of the sampling position. Content of the Utility Model
