Abstract

The invention discloses a PUR hot melt adhesive multifunctional reaction kettle with a double-mixing stirring function, the PUR hot melt adhesive multifunctional reaction kettle comprises a base, the top of the base is fixedly provided with a reaction kettle body, the inner side of the upper end of the reaction kettle is provided with an internal thread, and the top of the reaction kettle body is in threaded connection with a stirring mechanism through the internal thread. By adopting the structure, the driving motor is arranged to drive the stirring frame to rotate, so that the rotating shaft drives the propeller and the stirring paddle to rotate, a material is driven to roll through the propeller, and meanwhile, the stirring paddle is arranged to further stir and mix the rolled material, so that the mixing reaction efficiency of the device is effectively improved; when the reaction kettle is used, gas in the reaction kettle can be pumped through the vacuum pump, so that the vacuum of the reaction kettle is realized, and nitrogen and other gases required by reaction can be introduced through the other access port, so that the reaction kettle has the function of avoiding bottom crystallization and precipitation, and is wide in application range and worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a PUR hot melt adhesive multifunctional reaction kettle with double mixing and stirring functions. Background technique [0002] The broad understanding of the reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes; [0003] At present, there is only a single stirring blade inside the existing PUR hot melt adhesive reactor, and its mixing and stirring ability is limited. Mixing will easily lead to uneven mixing and stirring, which will cause problems in pro...
