Mixing unit

Abstract

A mixing apparatus includes a barrel, a stirring assembly, and at least one rectifying assembly. The barrel includes a surrounding wall around an axis, a mixing chamber, and a discharge section. The stirring assembly includes a main shaft extending along the axis and a plurality of first stirring sections. The at least one rectifying assembly includes a main body disposed in the discharge section, a through-hole communicating with the mixing chamber, and a flow divider disposed in the through-hole. The flow divider has a central shaft and a plurality of flow divider plates disposed on the central shaft. The through-hole has a plurality of flow channels. By disposing of the rectifying assembly in the discharge section, the central shaft is aligned with the center of the vortex generated by stirring to disrupt the vortex, and the product is then output through the flow channels, thereby eliminating the vortex pattern of the extruded finished product.

Claims

1. A mixing apparatus suitable for being driven by a drive assembly, the mixing apparatus comprising: a barrel including a surrounding wall around an axis, a mixing chamber defined by the surrounding wall, and a discharge section connected to one end of the surrounding wall and communicating internally with the mixing chamber along an extension direction of the axis. A mixing assembly includes a main shaft extending along the axis and disposed in the mixing chamber and rotatable by the drive assembly, a plurality of first mixing sections disposed on the main shaft and spaced apart along the axis; and at least one rectifying assembly including a main body disposed detachably in the discharge section, a through hole extending along the axis through the main body and communicating with the mixing chamber, and a diverting section disposed in the through hole and connected to the main body, the diverting section having a central shaft extending along the axis, and a plurality of diverting plates disposed at equal angular intervals on the central shaft and connected to the main body, the through hole having a plurality of flow channels defined by the central shaft, the diverting plates and the main body.

2. The mixing apparatus as described in claim 1, wherein, Each diverter extends from one side of the adjacent discharge section around the central shaft to the side away from the discharge section. Each diverter has a first end adjacent to the discharge section and a second end opposite to the first end along the axis. The first end has a top edge extending radially along the axis, and the second end has a bottom edge extending radially along the axis. When the top edge and the bottom edge are projected onto an imaginary plane perpendicular to the axis, they define a diverting angle between them, which is 90 degrees.

3. The mixing apparatus as described in claim 2, wherein, The number of such flow dividers is four, and the number of such flow channels is four.

4. The mixing apparatus as described in claim 1, wherein, Each of the diverter plates extends from one side of the adjacent discharge section along the extension direction of the axis to the side away from the discharge section.

5. The mixing apparatus as described in claim 4, wherein, The number of such flow dividers is eight, and the number of such flow channels is eight.

6. The mixing apparatus as claimed in claim 1, wherein, The mixing apparatus includes a plurality of rectifier components, which are detachably and coaxially connected along the extension direction of the axis, and one end of the connected rectifier components is detachably and disposed at the discharge section.

7. The mixing apparatus as claimed in claim 1, wherein, Each of the first stirring parts has a plurality of first stirring rods disposed on the outer peripheral wall of the main shaft and spaced at an angle to the axis of the main shaft. The stirring assembly also includes a plurality of second stirring parts connected to the surrounding wall and spaced apart along the extension direction of the axis. Each of the second stirring parts has a plurality of second stirring rods disposed on the inner side of the surrounding wall and spaced at an angle around the main shaft. The first stirring parts and the second stirring parts are arranged alternately and spaced apart along the extension direction of the axis.
