Abstract
The utility model discloses a vacuumizing device for the production of lithium ion battery paste. The vacuumizing device comprises a vacuum pump, and further comprises a return tank. One end of the return tank is connected with the vacuum pump through a first vacuum pipeline, and a second vacuum pipeline connected with a paste production tank is arranged at the other end of the return tank. A vacuum relief valve is arranged on the second vacuum pipeline. The return tank is arranged, and foreign matters and vacuum pump oil in the vacuum pipelines directly return to the return tank, and are prevented from returning to the paste production tank in vacuum relief, so that the production quality of the paste is ensured; and simultaneously, the vacuumizing device is convenient and easy to operate, and only the foreign matters in the return tank are required to be cleared regularly.
Description
Technical field
The utility model relates to a kind of vacuum extractor, and specifically a kind of lithium ion battery powder slurry is produced and used vacuum extractor.
Background technology
Lithium ion battery have voltage height, specific energy high, recycle often, advantage such as memory time is long; Not only on portable electric appts, be used widely like mobile phone, DV and laptop computer; And be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore increasingly high to the performance requirement of lithium ion battery.
Electrode plates is the important component part of lithium ion battery, is the core of lithium ion battery, and the quality of powder slurry slurry has directly determined the quality of electrode and even final battery.And the introducing of the foreign matter in the powder slurry production process will be bought serious hidden danger to battery safety, therefore must the strict introducing of controlling foreign matter in the whole process of battery.Powder slurry mainly is in order to eliminate the bubble in the slurry vacuumizing, but can be with in a spot of dry powder inspiration of the feed opening vacuum lead in vacuum, and simultaneous contains the air of a large amount of NMP gases; Very little by the vacuum pipe internal gas pressure; NMP liquefaction is for liquid, and when letting out vacuum, dry powder and NMP powder in the vacuum pipe can be back in the pulping tank; And occur when unusual when vacuum pump valve door; Also have pumping fluid in the pipeline, this can cause the pollution of slurry by the gross, brings serious hidden danger to battery safety.
The utility model content
The utility model provides the production of a kind of lithium ion battery powder slurry to use vacuum extractor for solving the problems of the technologies described above, and is intended to solve the problem that existing vacuum extractor can't avoid interior foreign matter of vacuum pipe and pumping fluid to be back to pulping tank internal contamination slurry.
A kind of lithium ion battery powder slurry is produced and is used vacuum extractor; Comprise vacuum pump, also comprise a return tank, said return tank one end is connected with said vacuum pump through first vacuum pipe; The other end is provided with second vacuum pipe that connects pulping tank, on said second vacuum pipe, is provided with one and lets out vacuum valve.
More excellent ground, said return tank bottom is provided with an atmospheric valve.
The utility model is through setting up a return tank; When letting out vacuum since vacuum pipe in foreign matter and pumping fluid directly be back in this return tank; Avoided foreign matter and pumping fluid in the vacuum pipe to be back in the pulping tank, thereby made the slurry quality of production be able to guarantee; Simultaneously easy to operate simple, only need regularly the foreign bodies removal in the return tank to be got final product.
Description of drawings
Fig. 1 is that lithium ion battery powder slurry is produced the structural representation with vacuum extractor;
Among the figure: 1, pulping tank 2, return tank 3, first vacuum pipe 4, atmospheric valve 5, vacuum pump 6, let out vacuum valve 7 second vacuum pipes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1; A kind of lithium ion battery powder slurry is produced and is used vacuum extractor, comprises vacuum pump 5, also comprises a return tank 2; Said return tank 2 one ends are connected with said vacuum pump 5 through first vacuum pipe 3; The other end is provided with second vacuum pipe 7 that connects pulping tank 1, on said second vacuum pipe 7, is provided with one and lets out vacuum valve 6, and return tank 2 bottoms are provided with atmospheric valve 4.
When letting out vacuum; Open and let out vacuum valve 6; Foreign matter and pumping fluid residual in first vacuum pipe 3 promptly are back in the return tank 2; So just prevented that foreign matter and pumping fluid in first vacuum pipe 3 are back in the pulping tank 1, thereby avoided foreign matter and pumping fluid to reflux the pollution of slurry in the pulping tank 1.Certain interval of time is opened the atmospheric valve 4 of return tank 2, and the foreign matters in the return tank 2 are discharged.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
Claims (2)
1. a lithium ion battery powder slurry is produced and is used vacuum extractor; Comprise vacuum pump; It is characterized in that, also comprise a return tank, said return tank one end is connected with said vacuum pump through first vacuum pipe; The other end is provided with second vacuum pipe that connects pulping tank, on said second vacuum pipe, is provided with one and lets out vacuum valve.
2. vacuum extractor according to claim 1 is characterized in that, said return tank bottom is provided with an atmospheric valve.
