The present disclosure relates to an application apparatus for mixing a plurality of components for producing a multicomponent mixture, in particular a polyurethane foam, and for introducing and/or applying the multicomponent mixture into and/or onto an object, in particular a lithium-ion battery, comprising: a mixing tube having a first closed end and a second end for discharging the multicomponent mixture from the mixing tube, wherein the mixing tube has a mixing space, a plurality of injection units arranged on the mixing tube, each configured to inject one of the plurality of components into the mixing space, a mixer arranged in the mixing space, configured to mix the injected components with one another, and a moving device configured to move the mixer between the first end and the second end. Furthermore, an application system comprising the application apparatus and a method for mixing a plurality of components for producing a multicomponent mixture and for introducing and/or applying the multicomponent mixture into and/or onto an object is disclosed.

The disclosure relates to an application system for mixing a plurality of components for producing a multicomponent mixture, in particular a polyurethane foam, and for introducing and/or applying the multicomponent mixture into and/or onto an article, in particular a lithium-ion battery, wherein the application system comprises an application device. Furthermore, a method for mixing a plurality of components for producing a multicomponent mixture and for introducing and/or applying the multicomponent mixture into and/or onto an article is disclosed.

A waste treatment apparatus includes: a body having a spherical shape and configured to accommodate a waste therein; and a stirring unit configured to stir the waste accommodated in the body. The stirring unit includes: a main shaft horizontally and rotatably disposed at a center portion in the inside of the body; a plurality of main shaft stirring blades having a flat plate shape, the plurality of main shaft stirring blades mounted on a surface of the main shaft; a plurality of support rods assembled to the main shaft at a predetermined interval, the plurality of support rods extending perpendicularly toward an inner peripheral surface of the body; and a plurality of stirring blades each having a rectangular flat plate shape, the plurality of stirring blades being mounted on distal ends of the plurality of support rods on an inner peripheral surface side of the body.

A mixing device includes a supporting base, a mixer assembly, a motor and a transmission mechanism. The supporting base has an installation part, and the mixer assembly is detachably connected to the installation part. The transmission mechanism includes a first transmission member and a second transmission member. The first transmission member is connected to the motor in a transmission manner. The second transmission member is connected to the stirring blade in a transmission manner. The second transmission member and the mixer assembly are connected to or separated from the installation part as an integral unit.
