Abstract

The invention relates to a reaction mixing device, in particular to a mixing device for production of polyethylene glycol, and belongs to the technical field of stirring devices. The mixing device comprises a reaction tank, a reaction tank cover, a circulation water cavity, a stirring assembly, a feeding assembly, a feeding motor, a stirring motor, a discharging outlet, a temperature sensor, a power of hydrogen sensor and display screen, and a gasket or a spherical surface line of the reaction tank and the reaction tank cover are adopted for sealing of the reaction tank and the reaction tank cover; the stirring assembly comprises a stirring shaft and at least one stirring blade, the stirring shaft penetrates through a stirring shaft through hole and is connected with a stirring motor, andthe stirring motor drives the stirring shaft to move; the feeding assembly comprises two feeding pipes and spraying heads, and one or more spraying heads are mounted at the lower ends of each feedingpipe; and the feeding pipes penetrate through feeding through holes to be connected with the feeding motor. According to the technical scheme, fully-mixing of materials can be achieved, self-cleaningof the reaction tank can also be achieved, the economical efficiency and the high efficiency are achieved.

Description

technical field [0001] The invention relates to a reaction mixing device, in particular to a mixing device for polyethylene glycol production, which belongs to the technical field of stirring equipment. Background technique [0002] Polyethylene glycol is non-toxic and non-irritating, has a slightly bitter taste, has good water solubility, and has good compatibility with many organic components. They have excellent lubricity, moisture retention, dispersibility, adhesives, antistatic agents and softeners, etc. They are widely used in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, paints, electroplating, pesticides, metal processing and food processing, etc. The industry has a very wide range of applications. Polyethylene glycol can be synthesized by gas phase or liquid phase polymerization. In industry, liquid phase polymerization is mostly used. Sodium hydroxide or potassium hydroxide is used as catalyst, and the reaction is carried out in a ste...
