Description

Technical Field

[0001] The utility model belongs to the technical field of SBR emulsion filtration, and in particular relates to an SBR emulsion filtration device for lithium ion batteries. Background Art

[0002] At present, the negative electrode binder for lithium-ion batteries is generally an emulsion type SBR. SBR is prone to water loss and crusting at the interface in contact with air. It is easy to clog the screen during application, and even cause poor coating appearance, seriously reducing the yield. The automatic feeding system of the automated production line can effectively reduce the introduction of crusting substances, but there will also be problems and risks of new crusting substances forming inside due to unclean pipeline cleaning. Therefore, many equipments with SBR emulsion automatic feeding systems have low utilization rates, and they are more inclined to use direct small bucket feeding when mixing ingredients. In order to avoid the introduction of SBR emulsion crusting substances in the small bucket, nylon filter bags or filter screens are generally used for filtration. At least two people are required to operate, and the operation process is cumbersome. In addition, there is a risk of introducing external foreign matter during the feeding process, which is easy to interfere with the abnormal analysis of the composition of the sieve. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a SBR emulsion filtering device for lithium ion batteries, thereby solving the problems in the above-mentioned background technology.

[0004] The purpose of the utility model is achieved as follows: a SBR emulsion filter device for lithium-ion batteries, which includes a bag body and a docking assembly, the docking assembly includes an external barrel cover and a throat hoop, and the caliber of the external barrel cover is the same as the caliber of the bag body, and the external barrel cover is detachably connected to the bag body through the throat hoop; the bag body includes a filter screen; a middle through hole is provided in the middle of the external barrel cover, and a thread is provided on the inner wall of the middle through hole; the external barrel cover includes an inner cover. The working principle is: 1. Before use, clean the filter bag first, and there is no foreign matter inside and outside the bag body; 2. Unscrew the SBR barrel cover (including the inner cover), and quickly tighten the filter device; 3. Weigh and record the initial weight of the SBR barrel containing the filter device; 4. Add the SBR emulsion filter net to the batching cylinder; 5. Weigh and record the final weight of the SBR barrel containing the filter device, and add the amount of SBR that meets the process requirements; 6. Unscrew the filter device and clean the filter bag, and tighten the original SBR barrel cover (including the inner cover).

[0005] Furthermore, the filter is made of nylon or stainless steel, and filters with different mesh sizes can be used according to the characteristics of the emulsion product.

[0006] Furthermore, a smooth portion is provided at the bottom of the external barrel cover, and a tight connection between the throat clamp and the external barrel cover is achieved through the action of the smooth portion.

[0007] Furthermore, an anti-skid support is provided on the top of the external barrel cover. The anti-skid support can facilitate the tightening of the filter device on the one hand, and prevent the bag body from falling off due to poor locking of the throat clamp on the other hand.

[0008] The beneficial effects of the utility model are as follows: by forming an integrated structure of a bag body and an external barrel cover, the bag body is a nylon filter bag or a stainless steel filter screen with different mesh requirements, the bag opening size is the same as the outer diameter of the SBR barrel cover, the external barrel cover is designed with an internal threaded through hole, and the bag opening and the external barrel cover are fastened by a throat clamp to form an integral structure.
