Description
Technical Field
The invention particularly relates to an axial-flow type efficient mixer.
Background
In the production process of polyurethane products, the efficiency and mixing degree of raw material mixing are important factors influencing the polyurethane products. In the prior axial flow mixers, a stationary element is arranged in a pipeline, and left-handed and right-handed helical plates of which the stationary element is twisted by 180 degrees are arranged in the pipeline at 90 degrees. The disadvantage is that only two raw materials can be mixed, two of the three raw materials need to be premixed when the three raw materials need to be mixed, and the high-efficiency simultaneous mixing of the three raw materials is difficult to realize. The polyurethane product usually needs to be added with additives such as a catalyst, a cross-linking agent, a chain extender and a foaming agent besides two raw materials, and the existing axial flow mixer cannot meet the requirement of simultaneously mixing the three raw materials, so that the production efficiency and the product quality are reduced.

the first feeding assembly comprises a first inlet pipe arranged outside the mixing pipeline and a first release pipe arranged on the inner wall of the mixing pipeline, the 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 has the same circle center as the mixing pipeline, and a plurality of second release holes which are uniformly distributed are formed in the second release pipe;
the flow guide assembly comprises a limiting bracket and three groups of flow guide units which are arranged in a staggered mode, and each flow guide unit consists of four flow guide sheets which are bent in a W shape.
Furthermore, the flow deflector is formed by bending a thin steel plate along the diagonal direction.
Furthermore, sealing sleeves are arranged at the joints of the first inlet pipe and the second inlet pipe with the mixing pipeline.
Furthermore, the first inlet pipe and the second inlet pipe are both provided with connecting flanges.
Has the advantages that: according to the invention, simultaneous feeding is realized through the I-shaped first feeding assembly and the O-shaped second feeding assembly, the fluid movement tracks of the I-shaped first feeding assembly and the O-shaped second feeding assembly can be mutually influenced, and the I-shaped first feeding assembly and the O-shaped second feeding assembly are mixed with the raw materials entering from the inlet of the mixing pipeline together, so that three raw materials with high efficiency are simultaneously mixed; the guide assembly increases the intensity of fluid movement, and the guide vanes bent in a W shape generate a strong shearing effect, so that complete mixing is further realized.
