Embodiment Construction
[0017] figure 1 Shows the mixing barrel used in the prior art. This mixing barrel is composed of an inner wall 4 of the mixing barrel and an outer wall 5 of the mixing barrel. The mixing barrel also includes a water inlet 1 and a water outlet 3. A circulating water channel 2 is provided between the outer wall 5 of the barrel. The contact area between the circulating water channel and the inner wall is the product of the height of the circulating water jacket and the circumference of the mixing barrel. When this kind of mixing barrel is working, the circulating water will enter the circulating water channel 2 through the water inlet 1 and flow out from the water outlet 3. However, it cannot be guaranteed that all the water is in a circulating state. The temperature of the inner wall of the mixing barrel will be different, and then appear The situation of local heating.

The invention relates to a temperature control system for an agitating barrel, including a flowmeter (1) arranged in upstream of a liquid inlet (2) for supplying cooling liquid for the liquid inlet; a temperature sensor (4) arranged in the agitating barrel for testing the temperature of slurry in the agitating barrel; an PLC (programmable logic controller) temperature controller connected between the flowmeter (1) and the temperature sensor (4) and receiving a temperature signal of the temperature sensor in real time and controlling the flowmeter (1) to start and close through the temperature signal, and presetting limit values of temperature upper limit and lower limit of the slurry on the PLC temperature controller. The PLC temperature controller controls the flowmeter in such a manner that: when the temperature tested by the temperature sensor exceeds the temperature upper limit value, the flowmeter is opened, and when the temperature tested by the temperature sensor exceeds the temperature lower limit value, the flowmeter is closed. According to the agitating barrel and the temperature control system therefore, the cooling efficiency of the agitating barrel can be improved, and the problem that the temperature of local part of the slurry is raised can be solved, so as to realize real-time constant temperature control.
Description
Technical field [0001] The invention relates to a temperature control device for the cooling liquid of a stirring barrel. The stirring barrel is used for stirring and cooling the pole piece slurry in the manufacture of power battery pole pieces. The barrel wall of the stirring barrel is cylindrical and is composed of The outer wall and the inner wall are formed, and the outer wall is provided with a liquid inlet for flowing in the cooling liquid and a liquid outlet for flowing out of the cooling liquid. Background technique [0002] At present, the manufacturing process of laminated power battery pole pieces can generally be divided into: pulping, coating, rolling, slicing, pole piece sorting, and pole piece baking. Power batteries are generally used in groups, and battery consistency is very demanding. As the first process in battery production, the key role of slurry is self-evident. The dispersion of slurry occupies a large part in battery consistency. proportion. Foreign li...
