[0002] Due to the many advantages of lithium batteries, lithium batteries are widely used in electronic instruments, digital and home appliances. An important part of lithium batteries is the selection of electrode materials. Electrode materials need to be used in conjunction with adhesives during processing. The performance of the adhesive is related to the performance and service life of the electrode material.

[0003] Before the raw materials of the adhesive are mixed and stirred in the reactor, it is usually necessary to filter out impurities contained in the raw materials for preparing the adhesive through a filtering device. After filtering the raw materials for preparing the adhesive for a period of time, the filter screen inside the existing filtering device needs to be replaced. However, when replacing the filter screen in the filtering device, the reactor needs to be stopped, which affects the preparation efficiency of the adhesive. Secondly, when replacing the filter screen in the existing filtering device, the operation process is relatively complicated, time-consuming and labor-intensive. In view of the above problems, the inventor proposes a processing device for an adhesive composite material for a positive electrode of a lithium battery to solve the above problems.
