Abstract
The utility model discloses a material supplying pot for coating a lithium ion battery, and the material supplying port can prevent slurry from being contacted with large-area air so as to reduce bad phenomena. The material supplying pot comprises a pot body; a feeding pipeline penetrates through the side wall of the pot body from the exterior of the pot body so as to enter the interior of the pot body; and a discharging pipeline is arranged at the bottom of the pot body. The material supplying pot is characterized in that one part, which enters the interior of the pot body, of the feeding pipeline extends downwards to the bottom of the pot body. According to the material supplying pot with such a structure for coating the lithium ion battery, one part, which enters the interior of the pot body, of the feeding pipeline extends downwards to the bottom of the pot body, so that the slurry can be prevented from being contacted with the large-area air; and on the other hand, the generation of air bubbles can be avoided, so that the coating quality of a lithium ion battery pole piece is guaranteed.
Description
Technical field
The utility model relates to a kind of lithium ion battery production process equipment, especially a kind of coating lithium ion cell gravitation tank.
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 safety requirements of lithium ion battery.In the lithium ion battery production process, coating process is the bottleneck that whole lithium battery is made, and in the production process of pole piece, plays crucial effects.The used slurry of coating machine is to be supplied with by gravitation tank.In the prior art; When gravitation tank injects slurry, as shown in Figure 1 through pipeline, feed pipe 1 passes sidewall in the sidewall upper of the tank body 2 of gravitation tank and gets into gravitation tank inside; The end of this feed pipe 1 is far away apart from the jar end of gravitation tank; Therefore after slurry enters into gravitation tank, directly wander the pot bottom of gravitation tank from the end of feed pipe 1, it is bigger that it wanders formation; Wander in the process and can contact with the air large tracts of land and oxidized, so may produce bad phenomenon such as white point applying a pole piece that is coated with out; On the other hand, can produce great amount of bubbles after slurry is wandered in the gravitation tank, thereby influence coating quality.
The utility model content
The technical problem that the utility model will solve provides a kind of slurry of can avoiding and contacts with the air large tracts of land, thereby reduces the coating lithium ion cell gravitation tank that bad phenomenon takes place.
For addressing the above problem; A kind of coating lithium ion cell gravitation tank of the utility model; Comprise tank body; Feed pipe passes tank wall from the tank body outside and enters into tank interior, and the bottom of tank body is provided with discharge pipe, it is characterized in that: the part that said feed pipe enters into tank interior extends downward tank base.
Adopt the coating lithium ion cell gravitation tank of the utility model structure; Part through feed pipe being entered into tank interior extends downward tank base; Can avoid slurry to contact with the air large tracts of land; On the other hand, can avoid the generation of bubble, thereby guarantee the coating quality of electrodes of lithium-ion batteries.
Description of drawings
Fig. 1 is a coating lithium ion cell gravitation tank structural representation of the prior art.
Fig. 2 is the structural representation of the utility model coating lithium ion cell gravitation tank.
The specific embodiment
In order to make those skilled in the art person understand the utility model technical scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
As shown in Figure 2; The coating lithium ion cell gravitation tank of the utility model; Comprise tank body 2; Feed pipe 1 passes tank wall from tank body 2 outsides and enters into tank body 2 inside, and the bottom of tank body 2 is provided with discharge pipe 3, and said feed pipe 1 enters into tank body 2 inner parts and extends downward tank body 2 bottoms.
Adopt the coating lithium ion cell gravitation tank of the utility model structure; Extend downward tank body 2 bottoms through feed pipe 1 being entered into tank body 2 inner parts; Can avoid slurry to contact with the air large tracts of land; On the other hand, can avoid the generation of bubble, thereby guarantee the coating quality of electrodes of lithium-ion batteries.
