Description

Technical Field

[0001] The utility model relates to the technical field of chemical machinery and equipment, in particular to a polymerization kettle shaft seal cooling and sealing device. Background Art

[0002] Polyvinyl chloride (PVC) paste resin is widely used in imitation leather, wallpaper, gloves, flame retardant conveyor belts, toys and other industries. With the development and expansion of the PVC paste resin market, the demand for PVC paste resin has further expanded, and the performance requirements and production capacity of PVC paste resin have also increased accordingly. Therefore, it is necessary to accelerate the improvement of the production process of PVC paste resin and increase its production capacity. 3 The polymerization kettle uses micro-suspension polymerization technology, where the mixture of vinyl chloride and water is dispersed in the polymerization kettle and reacted for 15 to 30 hours to form a micro-suspension latex, which is then spray-dried to obtain polyvinyl chloride paste resin. Since the high-viscosity material, latex, takes a long time to disperse and mix, the dispersion polymerization process will release a large amount of heat. If this heat is not removed in time, the material temperature will rise too quickly, causing damage.

[0003] The large-scale polyvinyl chloride resin polymerization kettle with patent application number 201620010482.3 has the following advantages: by designing the stirring shaft and the stirring paddle as an internal cooling system, and by designing the jacket as an external cooling system, the material is uniformly cooled from the inside and the outside at the same time, and the cooling effect is good, so that the temperature in the polymerization kettle is maintained at the temperature required by the process, thereby ensuring the stability of the polyvinyl chloride paste resin production process and the product quality. The utility model is particularly suitable for large-capacity polymerization kettles, but the cooling system of the above case is not easy to install and disassemble, and the cooling system will be damaged after long-term use. However, there is no installation and disassembly device in the above case. When the cooling system is damaged, the polymerization kettle cannot be cooled, affecting the continued operation of the polymerization kettle, and the practicality is not high.
