Novel cooling structure for tangent type rotator of internal mixer

Abstract

The invention discloses a novel cooling structure for a tangent type rotator of an internal mixer, which relates to the tangent type rotator of the internal mixer. The novel cooling structure for the tangent type rotator of the internal mixer disclosed by the invention comprises a central chamber (2), long prismatic chambers (4), (5), (6) and (7), wherein the long prismatic chambers (6) and (7), the central chamber (2), and the long prismatic chambers (5) and (6) are communicated in turn in a F-F axial section through a slotted hole (3); rotator long prismatic chambers (4) and (7) are communicated and the long prismatic chambers (5) and (6) are communicated in an A-A axial section through the slotted hole; and the long prismatic chambers (4), (5), (6) and (7) and the central chamber (2) are communicated in the A-A axial section. Aiming at the conventional tangent type rotator cooling structure, the novel cooling structure for the tangent type rotator of the internal mixer is additionally provided with stiffening ribs and forced water circulation channels are formed, so the area of the cooling water channels are enlarged, the cooling efficiency and the cooling effect are improved, the strength and the rigidity of the rotator are also improved, and the section coefficient of bending resistance is increased.

Description

technical field [0001] The invention relates to a tangential rotor of an internal mixer, in particular to a novel cooling structure of the tangential rotor. Background technique [0002] Due to the complex and irregular shape of the cooling form of the rotor of the internal mixer, the cooling effect is also different. For example, the tangential four-sided rotor of the traditional Japanese Kobelco internal mixer generally adopts inner cavity spray cooling (such as figure 1 shown), the three-dimensional shape of the cooling cavity is as follows figure 2 shown; its axial section is as image 3 shown. For example, the tangential synchronous four-edged rotor of the traditional Farrer internal mixer adopts forced cooling in the inner cavity, such as Figure 4 , Figure 5 shown; its axial section is as Figure 6 shown. For internal mixers of the same specification, although the cooling surface area and cooling effect of the Farrer rotor are better than those of Japanese Ko...

Problems solved by technology

However, they all have the disadvantages of not only small cooling surface area in the inner cavity of the rotor, but also large water capacity in the inner cavity, slow cooling medium flow rate, and poor cooling effect.
