Description

Technical Field

[0001] The utility model relates to the technical field of synthetic solution-polymerized rubber, in particular to a hot water dispersion device for a solution-polymerized rubber stripping kettle. Background Art

[0002] Solution rubber refers to synthetic rubber produced by solution polymerization. It is prepared by solution polymerization of polymerized monomers under the action of catalysts. In addition to high molecular rubber, the polymerized rubber solution also contains solvents and unreacted monomers. In order to separate the solvent from the unreacted monomers, the rubber solution in the production of solution rubber generally uses hydrolysis to separate the solvent from the rubber product. That is, the rubber solution containing the solvent is sprayed into a stripping kettle with stirring, and mixed with hot water and steam under the action of stirring. The solvent and monomer are flash vaporized and enter the vapor phase on the top of the kettle for cooling and recovery. After the solvent is removed, the rubber becomes rubber particles suspended in hot water and is sent to the subsequent process section for further drying to become a finished product.

[0003] According to the search, the Chinese patent document, announcement number: CN209138020U, discloses a hot water dispersion device for a solution rubber stripping kettle, which disperses hot water through a spraying plate, and at the same time, the hot water washes the solid rubber particles entrained in the rising vapor phase in the kettle, reducing the entrainment of solid rubber particles in the vapor phase at the top of the stripping kettle. The hot water feed pipe extends to the spraying plate in the kettle, and the hot water flows to the spraying plate; the spraying plate is installed in the vapor phase space in the stripping kettle, located on the stirring shaft and rotates with the stirring shaft; the hot water flows to the spraying plate inside the stripping kettle and enters the stripping kettle, and the spraying plate rotates with the stirring shaft to swing the hot water around and disperse it, and at the same time, the hot water washes the vapor phase in the stripping kettle to reduce the entrainment of solid rubber particles. However, during the use process, although the spraying plate can rotate with the stirring shaft to swing the hot water around and disperse it, when the hot water is dispersed and thrown out, most of the heat of the hot water rushes to the kettle wall under the action of the throwing force, resulting in a sparse distribution of hot water between the spraying plate and the kettle wall, which easily leads to uneven washing of the vapor phase and the appearance of washing dead corners.

Then, when hot water is introduced, the dispersion disc rotates and throws out the hot water, so as to wash the solid rubber particles entrained in the upward vapor phase in the kettle, reduce the entrainment amount of solid rubber particles in the top vapor phase of the stripping kettle. At the same time, when the hot water is thrown out and dispersed, part of the hot water drops to the bottom side of the dispersion disc through the through holes, and then the vapor phase at the bottom side of the dispersion disc is washed while the dispersion sleeve rotates, which is beneficial to increase the washing area and efficiency, further reduce the entrained solid rubber particles, and extend the cleaning cycle of the stripping kettle;
