Double-cone dynamic mixer

Abstract

The invention discloses a double-cone dynamic mixer, which comprises a mixing chamber with a feed opening and a discharge opening, wherein fixed plates and moving plates matched in a rotating manner are coaxially arranged in the mixing chamber; butted working surfaces are arranged between the fixed plates and the moving plates; feed flow passages and discharge flow passages communicated with the discharge opening are formed in the working surfaces of the fixed plates; diversion flow passages communicated with the feed opening are formed in the working surfaces of the moving plates; in a relative rotating process of the fixed plates and the moving plates, the diversion flow passages are alternately communicated with the feed flow passages and the discharge flow passages. According to the double-cone dynamic mixer, the flow passages are conically distributed, so that the extension of length of the flow passages is facilitated, and more fixed and moving plate combinations can be distributed within a finite distance; the double-cone dynamic mixer has good diversion effects, and is complete in self mixing, strong in fluid shear force, wide in application range and free of flowing dead angles.

Description

technical field [0001] The invention belongs to the design field of mechanical mixing devices, in particular to a double-cone dynamic mixer. Background technique [0002] In daily life, the use of polymers plays an irreplaceable role. At present, the demand for textiles in the world has been greatly improved, and natural fibers such as cotton and hemp and chemical fibers such as viscose, acetic acid, and cupro have been far from satisfying people's needs. Synthetic fibers represented by polyester occupy a dominant position. With the maturity of the melt direct spinning process, the scale of a single production line has reached the level of 100,000 tons per year. The ensuing disadvantage is that the flexibility of varieties is greatly limited, and it is impossible to realize small batch production of differentiated and functional fibers such as antibacterial, flame retardant, and colored silk. [0003] In traditional chemical fiber production enterprises, when producing fu...

Problems solved by technology

[0005] The above-mentioned static mixer improves the quality of fiber products to a certain extent. However, since the static mixer needs to consider the pressure drop of the fluid, the flow channel is generally wide, and the number of divisions of the fluid by the single-layer mixing sheet is small. The layer of the mixing sheet The number is limited, and the fluid can only be cut and divided for a limited number of times; the shearing and mixing effects of the fluid are not ideal
