Description

Technical Field

[0001] The utility model relates to a production reaction kettle with quantitative feeding, belonging to the field of reaction kettles. Background Art

[0002] With the rapid development of industrial production, the performance and technical level of reactors, as key equipment for chemical reactions, play a vital role in improving production efficiency, ensuring product quality, and achieving energy conservation and emission reduction. However, the reactors in the prior art still have some deficiencies in material handling and are difficult to meet the higher requirements of modern industrial production.

[0003] First, before the materials enter the reactor, there is often a lack of sufficient stirring and fluidity enhancement measures, which leads to uneven distribution of materials when entering the reactor, which can easily cause local concentrations inside the reactor to be too high or too low, affecting the uniformity and efficiency of the reaction. At the same time, materials with poor fluidity may also cause blockage and wear during transportation, increasing production costs and maintenance difficulties. Secondly, although preheating plays a vital role in chemical reactions, existing reactor systems are usually insufficient in terms of material preheating. The purpose of preheating is to allow the materials to reach a suitable reaction temperature before entering the reactor to increase the reaction speed and efficiency, while avoiding stress and uneven reactions caused by temperature differences. However, the preheating equipment in the prior art is often independent of the reactor and fails to be effectively integrated with the feeding and stirring process, resulting in low preheating efficiency and serious energy waste. .

[0036] The working principle of the above embodiment is:

[0037] First, materials are put into the silo 5 through the feed pipe 6, and then the heating pipe 13 is started.
