Operation method for reaction kettle applied to automatic production of high polymer material polyurethane

Abstract

The invention relates to the technical field of automatic production of polyurethane, and discloses an operation method for a reaction kettle applied to automatic production of a high polymer material, namely polyurethane. The reaction kettle comprises a top seat, wherein symmetrically distributed hydraulic rods are fixedly connected to two sides of the bottom of the top seat, and a groove is formed in the bottom of the top seat. According to the operation method of the reaction kettle for automatically producing polyurethane, a fixed pile is fixedly connected to the outer part of a rotating rod, cylindrical holes which are uniformly distributed are formed in the outer side of the fixed pile, stirring rods which are symmetrically distributed are fixedly connected into the cylindrical holes in the outer side of the fixed pile, and meanwhile, a stirring ring is fixedly connected to the outer part of the fixed pile. According to the invention, the outer part of the stirring rod is in a curved surface shape and the stirring ring is spirally arranged, so the reaction kettle can be ensured to quickly stir materials, and the problem that a stirring device is difficult to operate when the motor of an existing device is started is solved.

Description

technical field [0001] The invention relates to the technical field of automatic production of polyurethane, in particular to a reaction kettle operation method for automatic production of polymer material polyurethane. Background technique [0002] The full name of polyurethane is polyurethane. In addition to carbamate, polyurethane macromolecules can also contain ether, ester, urea, biuret, allophanate and other groups. Polyurethane materials are very versatile. It can replace rubber, plastic, nylon, etc., and is used in airports, hotels, building materials, automobile factories, coal mines, cement factories, high-end apartments, villas, landscaping, colored stone art, parks, etc., so people need it when making polyurethane A reaction kettle for automatic production of polymer material polyurethane and an operation method thereof.

Problems solved by technology

[0003] At present, there are many types of reactors on the market. In the existing reactors, when there are too many materials placed, the stirring device inside the reactor is difficult to start and operate. At the same time, it is difficult to fully turn and mix the materials during the stirring process. In addition, most of the feed holes of the existing reactors are directly connected. The feed holes of such devices often accumulate water vapor during use, which causes the materials to stick to the inner wall of the feed hole, and the reactor is High temperature will be generated during operation, and the temperature control of the existing device is not very good. Therefore, we propose a reactor for automatic production of polymer material polyurethane and its operation method
