However, the existing internal mixer includes a mixing chamber, a mixing shaft, an upper top bolt and a lower top bolt, the upper top bolt and the lower top bolt are respectively movably connected with the banbury shaft, and the banbury shaft is located in the banbury chamber. During the working process of the machine, the mixing chamber, the mixing shaft and the lower top bolt are all in contact with the feed liquid. Due to the high temperature of the feed liquid, the contact surface between the mixing chamber, the banbury shaft and the lower top bolt and the feed liquid Changes in stress can easily damage the internal structure of the contact surface, causing the contact surface of the mixing chamber, the bottom bolt of the mixer shaft and the material liquid to be easily worn, which greatly reduces the service life of the mixer shaft and makes the overall mixer Unreasonable structural layout

The invention relates to the field of machinery, in particular to an internal mixer. The invention adopts the technical scheme as follows: the internal mixer comprises a mixer chamber, a mixer shaft and a lower ram, wherein a first coolant gallery is arranged on one side wall of the mixer chamber, a second coolant gallery is arranged on one side wall of the lower ram, a third coolant gallery is arranged on the mixer shaft, and the first coolant gallery, the second coolant gallery and the third coolant gallery are connected with a cooling system respectively. The internal mixer has the advantages that the temperature of the contact surfaces of the mixer chamber, the mixer shaft and the lower ram with feed liquid are reduced greatly, so that the internal stress of the contact surfaces of the mixer chamber, the mixer shaft and the lower ram with the feed liquid is not easy to change, the internal structures of the contact surfaces are protected, the contact surfaces of the mixer chamber, the mixer shaft and the lower ram with the feed liquid are not easy to wear, the service life of the mixer shaft is prolonged on the whole, and the structure layout is more reasonable.
Description
technical field [0001] The invention relates to the field of machinery, in particular to an internal mixer. Background technique [0002] The internal mixer is used for rubber, plastic and mastication and mixing of various rubber materials and plastics. It melts the PVC mixture in a very short time and promotes gelation. Colorants and foaming agents are added and mixed here. However, the existing internal mixer includes a mixing chamber, a mixing shaft, an upper top bolt and a lower top bolt, the upper top bolt and the lower top bolt are respectively movably connected with the banbury shaft, and the banbury shaft is located in the banbury chamber. During the working process of the machine, the mixing chamber, the mixing shaft and the lower top bolt are all in contact with the feed liquid. Due to the high temperature of the feed liquid, the contact surface between the mixing chamber, the banbury shaft and the lower top bolt and the feed liquid Changes in stress can easily da...
