Rotating speed self-adjusting type lithium battery cell slurry fluctuation type stirring equipment

Abstract

The invention discloses rotating speed self-adjusting type lithium battery cell slurry fluctuation type stirring equipment which comprises a stirring box, a motor is fixedly connected to the upper endof the stirring box, a movable end of the motor penetrates through the upper end of the stirring box and is fixedly connected with a rotating shaft, and a plurality of stirring rods are fixedly connected to the side wall of the rotating shaft. A heating plate is fixedly connected to the bottom in the stirring box, a sliding plug cavity is formed in the side wall of the stirring box, and a conductive plate is slidably connected to the inner wall of the sliding plug cavity in a sealed mode. The conductive plate continuously slides up and down on the inner wall of the sliding plug cavity under the action of expansion force of expansion liquid and magnetic repulsion of a permanent magnet plate to an electromagnet, so that resistance of a resistance plate connected into a circuit is continuously changed, then current flowing through the motor is continuously changed, the motor drives the rotating speed of the stirring rods to be continuously changed, and further cell slurry is subjected tofluctuation type stirring; and moreover, manual intervention is not needed, heat generated at the heating plate is reasonably utilized, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a self-adjusting rotational speed type lithium battery core slurry wave stirring equipment. Background technique [0002] Lithium battery refers to the battery containing lithium in the electrochemical system. Lithium battery can be divided into lithium metal battery and lithium ion battery. When producing lithium battery, it is necessary to stir the lithium battery cell slurry. The dispersion and uniformity of active materials directly affect the movement of lithium ions between the two poles of the battery, so the dispersion quality of the slurry directly affects the quality of subsequent lithium-ion battery production and the performance of its products. [0003] Since the lithium battery cell slurry is composed of solid and liquid, and when the cell slurry is stirred, the cell slurry located in a remote position in the stirring box cannot be stirred, so tha...

Problems solved by technology

[0003] Since the lithium battery cell slurry is composed of solid and liquid, and when the cell slurry is stirred, the cell slurry located in a remote position in the stirring box cannot be stirred, so that the cell slurry in this area is mixed unevenly , affecting the subsequent use, so at present, when stirring the electric core slurry, the rotation speed of the motor is mostly adjusted, and then the rotation speed of the stirring rod is adjusted, and the electric core slurry is stirred in a fluctuating manner, but this requires specialized personnel to constantly adjust the rotation speed of the motor. Adjustment is labor-intensive, and in order to speed up the stirring and mixing efficiency of the electric core slurry, a heating plate is usually installed in the stirring box to heat the electric core slurry, but when the electric core slurry is stirred, the heat is not carried out. Reasonable use, resulting in energy loss
