Description

TECHNICAL FIELD

[0001] The utility model relates to sealing technical field, concretely relates to a sealing structure for the reaction kettle of acrylic resin production. BACKGROUND

[0002] In modern chemical industry, the production of acrylic resin occupies a pivotal position, and is widely used in many fields such as coatings, inks, adhesives and textile auxiliaries due to its excellent performance. As the key core equipment for acrylic resin production, the reaction kettle creates the necessary reaction place for polymerization reaction, and its operating condition is directly related to product quality, production efficiency and operation safety and many other important aspects.

[0003] In the whole production process of acrylic resin, the reaction kettle needs to run under specific and relatively harsh conditions. On the one hand, the reaction usually needs to be maintained in a precisely controlled temperature range, for example, from tens of degrees Celsius to hundreds of degrees Celsius, while accompanied by changes in internal pressure during the reaction process; on the other hand, in order to ensure that the reactants can be fully mixed and uniform, the stirring device continuously operates in the reaction kettle. These complex working conditions put extremely strict requirements on the sealing structure of the reaction kettle, only a reliable sealing structure can prevent the leakage of materials in the reaction kettle and prevent the mixing of foreign matter from the outside, thereby ensuring the smooth progress of the reaction in a stable environment.

[0004] In the technical solution of the published application No. 202021926294.8, although the sealing sleeve structure can play a certain sealing role in the initial design, it has obvious limitations in actual application in the production process of acrylic resin. Due to the characteristics of high temperature, corrosive materials and continuous stirring action in the production environment of acrylic resin, the sealing sleeve will inevitably wear and age after a long time of use. Once the sealing sleeve is worn and aged, the part that originally tightly fits to achieve sealing will have gaps, causing the sealing performance to drop sharply, eventually leading to leakage of acrylic resin materials and reaction gases in the reaction kettle. Not only does this leakage cause waste of materials and increase production costs, but the leaked materials may also pollute the surrounding production environment and even cause certain safety hazards, such as some volatile and flammable acrylic monomers leaking, which can easily cause safety accidents when encountering fire or static electricity.

[0016] During the operation of the reaction kettle, even if the sealing gasket one and the sealing gasket two are gradually thinned due to the friction with the synchronously rotating round block and the round seat, the inner spring and the outer spring can still continuously press them in the corresponding positions by the elastic force, so that the sealing effect is not affected, the adaptive mechanism overcomes the problem that the sealing performance of the traditional sealing structure is sharply reduced after the parts are worn, greatly prolongs the effective sealing time of the overall sealing structure, reduces the material leakage caused by the sealing failure, and reduces the material waste and production cost.
