Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The embodiment relates to a lithium battery negative electrode material screening device, as shown in fig. 1 and fig. 2, the lithium battery negative electrode material screening device comprises a box body 1 with a feeding hole 101 and a discharging hole 102, and a screen frame 2 arranged in the box body 1 and located between the feeding hole 101 and the discharging hole 102, wherein the screen frame 2 is arranged on the bottom wall of the box body 1 through an elastic piece, a rotating motor 3 is fixedly connected onto the screen frame 2, and an eccentric wheel 4 is fixedly connected onto a power output shaft of the rotating motor 3.
In the above structure, the box body 1 is a cuboid or cube structure with a hollow interior, and the feed inlet 101 and the discharge outlet 102 are respectively located on the top wall and the bottom wall of the box body 1. The screen frame 2 of the present embodiment includes a bottom plate 202, and a surrounding barrier fixedly connected to the bottom plate 202, the surrounding barrier includes two side surrounding barriers 203 and an end surrounding barrier 204, and a notch 205 for large particle impurities to fall down is formed at the end of the screen frame 2 corresponding to the hinged end of the mounting plate 6 described below. In this embodiment, a plurality of filter holes 201 are formed in the bottom plate 202 and the two side barriers 203 of the screen frame 2, respectively, and the filter holes 201 can allow the negative electrode material meeting the particle size requirement to fall down. In this embodiment, the rotating electrical machine 3 is fixedly connected to the lower surface of the bottom plate 202, and in order to ensure the vibration balance of the screen frame 2, the rotating electrical machine 3 in this embodiment is a double-shaft electrical machine, and the eccentric wheels 4 are fixedly connected to two power output shafts of the double-shaft electrical machine. In this embodiment, since the screen frame 2 is fixedly connected with the elastic member 5, when the eccentric wheel 4 rotates, the eccentric wheel 4 drives the screen frame 2 to vibrate due to the change of the gravity center, so as to form screening.
For the arrangement of the integral structure, in this embodiment, a mounting plate 6 is disposed on the bottom wall of the box body 1, and a through hole 601 is formed in the middle of the mounting plate 6, the bottom end of the elastic member 5 is fixedly connected to the mounting plate 6, the top end of the elastic member 5 is fixedly connected to the bottom plate 202 of the screen frame 2, and the elastic member 5 is a spring or a plate spring.
