Problems solved by technology

[0003] Most of the combined polyether production equipment on the market currently uses sensors to weigh, and only one raw material can be added each time, and when the combined polyether production equipment adds raw materials, each raw material will be separated. The single addition time is longer, which will reduce the production efficiency of the combined polyether and reduce the production capacity

Abstract

The invention relates to the technical field of polyurethane combined polyether production, and discloses equipment and a process for producing polyurethane combined polyether, the equipment comprises a material conveying pipe, the top end of the material conveying pipe is fixedly connected with seven material discharging valves, the top ends of the seven material discharging valves are fixedly connected with metering pumps, the top ends of the metering pumps are fixedly connected with flowmeters, and the flowmeters are fixedly connected with the material conveying pipe. The top end of the flow meter is fixedly connected with a material storage barrel, the top end of the material storage barrel is fixedly connected with an upper cover, and one side of the top end of the upper cover is fixedly connected with a feeding port; various raw materials and various auxiliaries are fed and metered at the same time, the metering pump is matched with the flow meter, a formula is input, and metering is intelligently controlled, so that the combined polyether production capacity efficiency is improved by about 5 times compared with that of equipment in the current market, meanwhile, the metering accuracy of the raw materials and the auxiliaries in the production link is improved, and the production efficiency is improved. Therefore, the number of workers is reduced, the production cost is reduced, and the production efficiency of the combined polyether is improved.

Description

technical field [0001] The invention relates to the technical field of producing polyurethane combined polyether, more specifically, the invention relates to a kind of equipment and process for producing polyurethane combined polyether. Background technique [0002] Combined polyether is one of the main raw materials of polyurethane rigid foam, also known as white material, and it is called black and white material together with polymeric MDI. [0003] Most of the combined polyether production equipment on the market currently uses sensors to weigh, and only one raw material can be added each time, and when the combined polyether production equipment adds raw materials, each raw material will be separated. The time for a single addition is longer, which will reduce the production efficiency of the combined polyether and reduce the production capacity. Contents of the invention [0004] In order to overcome the above-mentioned defects of the prior art, the present inventio...
