Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the specific implementation:

as shown in fig. 1 to 4, a high-efficiency double-cone mixing barrel comprises a barrel body 1; the device also comprises a rotating shaft 2 which is arranged in the cylinder body 1 in a rotatable manner; a supporting seat 3 is arranged on the inner side wall of the cylinder body 1 in a right-to-right manner, and an installation cavity 4 is formed in the supporting seat 3; two ends of the rotating shaft 2 extend into the mounting cavity 4, scroll springs 5 are sleeved at two ends of the rotating shaft 2, the centers of the scroll springs 5 are fixed on the rotating shaft 2, and the tail ends of the scroll springs 5 are fixed on the side wall of the mounting cavity 4; the rotating shaft 2 is provided with a stirring blade 6.

Therefore, with the rotation of the cylinder body 1, partial materials in the cylinder body 1 can fall onto the stirring blades 6 due to the existence of the stirring blades 6, and the problem that the materials are agglomerated and directly fall from a high end to a low end to cause insufficient mixing is avoided; meanwhile, as the materials fall onto the stirring blades 6, the rotating shaft 2 rotates under the action of gravity to enable the volute spiral spring 5 to be twisted, and the materials simultaneously begin to fall to the low end of the barrel 1 along with the continuous rotation of the barrel 1; the acting force that the material produced on stirring leaf 6 is less than volute spiral spring 5's torsional force for axis of rotation 2 reversal, the material of remaining on stirring leaf 6 or on the rotation path is thrown other positions in barrel 1, makes the material fully disperse, improves mixing efficiency. Meanwhile, the scheme does not increase extra motors and the like to generate redundant energy consumption, and the production cost is further reduced.

In this embodiment, as shown in fig. 3, the rotating shaft 2 has at least two stirring blades 6 arranged along the length direction thereof, and the stirring blades 6 are distributed in an array along the circumferential direction of the transmission shaft. Thus, when the rotating shaft 2 is in a rotating state, the stirring blades 6 can better handle materials falling from different positions, and the stirring blades 6 can be guaranteed to receive the falling materials, so that the materials are fully stirred and mixed. In practice, the number of the stirring blades 6 is preferably 3, so that the offset angle between each stirring blade 6 is 120 degrees; stirring leaf 6 reply that can be more comprehensive comes from the material of different positions for the effect that slows down the impact force is more.
