Polyether continuous online mixing equipment

Abstract

The invention relates to polyether continuous online mixing equipment. The polyether continuous online mixing equipment is characterized by comprising a reactant storage system, a reactant high-precision online metering system, a continuous auxiliary material metering system, a mixing system and a mixed raw material storing and conveying system. Online adjustment of raw materials of different formulas can be adjusted in an online manner, metering precision is high, and production efficiency is improved.

Description

technical field [0001] The invention relates to a mixing equipment for polyurethane raw materials, in particular to a continuous online mixing equipment for polyether. Background technique [0002] With the rapid development of my country's automobile industry and the wide application of polyurethane foam products in the automobile industry, how to adapt to the different needs of various car interiors in terms of environmental protection, comfort, and cost control A subject of joint research by component manufacturers. [0003] In the past, there were two production modes. One is that manufacturers of automotive interior parts directly purchase polyol combination raw materials that have been added with various auxiliary materials and additives from polyurethane raw material suppliers, and the other is to purchase various monomer raw materials, and then After being weighed according to the proportion, it is stirred and mixed with a material tank to form a polyol combination r...

AI Technical Summary

Problems solved by technology

The raw material formula purchased by the first method has been finalized, which cannot adapt to the adjustment of the process formula at any time during the production process, and the cost of purchasing raw materials is relatively high. The second method uses an electronic scale to weigh different monomer raw materials and injects them Stir and mix in the material tank. In this way of batching, only one formula raw material can be mixed each time before mixing other formula raw materials. In order to make the raw materials mix evenly, the waiting time for each stirring and mixing is long, and it is easy to mix the raw materials during the mixing process. Reaction and volatilization will cause environmental pollution, and affected by the weighing accuracy of the electronic scale, there will be certain differences in the same formula raw materials mixed each time, and the accuracy of the electronic scale is easily affected by ambient temperature, humidity, and vibration, and regular calibration is required

However, with the continuous increase of automobile production and the mixed production of interior parts of different models, it is necessary to have strong process adjustment flexibility in the production process, to realize online adjustment of different formula raw materials, and to flexibly control each mixing weight, and to mix various raw materials. The specific metering accuracy requirement is ≤5‰, so the existing mixing equipment cannot realize the online adjustment of automatic batching, the production efficiency is low, and the production cost is high
