Axial-flow type efficient mixer

Abstract

The invention discloses an axial-flow type efficient mixer which comprises a mixing pipeline, a first feeding assembly, a second feeding assembly and a flow guide assembly. The first feeding assemblyand the second feeding assembly are arranged at the front end of the mixing pipeline, and the flow guide assembly is arranged on the rear side in the mixing pipeline; a first release pipe vertically penetrates through the circle center of the mixing pipeline, and a plurality of first release holes which are uniformly distributed are formed in the first release pipe; the second feeding assembly comprises a second inlet pipe arranged outside the mixing pipeline and a second release pipe arranged in the mixing pipeline, the second release pipe is annular and is concentric with the mixing pipeline, and a plurality of second release holes which are uniformly distributed are formed in the second release pipe. According to the invention, through the I-shaped first feeding assembly and the O-shaped second feeding assembly, simultaneous feeding is realized, and the fluid movement tracks of the I-shaped first feeding assembly and the O-shaped second feeding assembly can influence each other andare mixed with raw materials entering from the inlet of the mixing pipeline, so that high-efficiency simultaneous mixing of the three raw materials is realized.

Description

technical field [0001] The invention specifically relates to an axial-flow high-efficiency mixer. Background technique [0002] In the production process of polyurethane products, the efficiency and degree of mixing of raw materials are important factors affecting polyurethane products. Various existing axial flow mixers are provided with static elements in the pipeline, and the static elements are left-handed and right-handed spiral plates twisted 180 degrees, and those are installed in the pipeline at 90 degrees. Its disadvantage is that only two kinds of raw materials can be mixed, and when three kinds of raw materials need to be mixed, two of them need to be pre-mixed, and it is difficult to achieve high-efficiency simultaneous mixing of the three raw materials. However, polyurethane products often need to add catalysts, crosslinking agents, chain extenders, foaming agents and other additives other than the two raw materials. The existing axial flow mixer cannot meet th...

Problems solved by technology

Its disadvantage is that only two kinds of raw materials can be mixed, and two of them need to be pre-mixed when three kinds of raw materials need to be mixed. It is difficult to achieve high-efficiency simultaneous mixing of the three raw materials.

However, polyurethane products often need to add catalysts, crosslinking agents, chain extenders, foaming agents and other additives other than the two raw materials. The existing axial flow mixer cannot meet the needs of mixing the three raw materials at the same time. production efficiency and product quality
