Abstract

The present invention relates to a stirring container that aims to improve production speed by improving heat transfer capacity, by configuring the exterior of the container in a double layer for heat exchange of the stirring material and flowing cold (hot) water into this space to absorb heat from or transfer heat to the stirring material inside the container to control the temperature, and to reduce the side thickness of the receiving portion in which the stirring material is received, and to reinforce the reduced thickness by attaching a reinforcing part to the outer circumference of the receiving portion to reinforce strength and improve heat transfer capacity, thereby enabling the stirring container to transfer more heat than a stirring container of a conventional structure within a limited heat transfer area.

Description

Stirring Container The present invention relates to a stirring vessel, and more specifically, to a stirring vessel for a stirrer that uses external mechanical energy to make two or more substances of different physical or chemical properties into a uniformly mixed state. Currently commercialized planetary mixers for secondary battery slurry mixers have a driving power of 110 kW and an equipment weight of about 35 tons. As such large power is applied to the stirring, the driving force is transmitted to the slurry as frictional force, and consequently, the slurry generates heat. Since the cathode solvent for secondary battery slurries is NMP, which is a flammable organic solvent, there is a risk of explosion if the temperature of the slurry rises during stirring. In addition, although the solvent for the negative electrode of the secondary battery slurry is water, if the slurry temperature rises too high during stirring, problems with the stirring quality will occur, so a low temperature must be maintained during stirring. For this reason, a mixer that stirs the slurry usually uses a double-walled container and has a cooling system in which cooling water is circulated inside the double-walled container to receive heat from the slurry at the inner wall and transfer it to the cooling water, and then the cooling water is discharged out of the container, cooled in a cooling tower, and then circulated back into the double space of the container. In Korean Registered Patent Publication No. 10-1569523 ('Stirring Tank for Temperature Control', Nov. 10, 2015), a first heat conduction pipe having a long pipe shape with a through hole is positioned inside a container, and one end is connected to the lower part of the stirring pipe, and the other end is connected to the upper part of the stirring pipe. As a refrigerant or heat transfer fluid discharged to the lower part of the stirring pipe through an inlet pipe flows into the first heat conduction pipe and cools or heats the first heat conduction pipe, a material contained in the container and in direct contact with the first heat conduction pipe is efficiently cooled or heated. In addition, the surface of the container is cooled or heated by moving up and down while making spiral contact with the surface of the container through a second temperature control means that wraps around the outer surface of the container to form a sealed space inside. Although the temperature of the slurry can be controlled through a first heat conduction pipe and a stirring pipe formed inside the stirring vessel and a second temperature control means formed outside the vessel, there are issues with the first heat conduction pipe or the stirring pipe being difficult to repair and high manufacturing costs, and the spiral-shaped heat conduction pipe on the inner wall of the conventional stirring vessel cannot sufficiently reinforce the strength of the inner wall of the stirring vessel, thus limiting the reduction of the inner wall thickness.
