Description

Technical Field

[0001] The utility model relates to the field of recycling of waste power batteries, in particular to a waste power battery crushing device. Background Art

[0002] With the popularization of new energy vehicles, the recycling of waste power batteries is imminent. Power battery recycling refers to the recycling and reuse of power batteries that are scrapped, damaged or no longer used. The recycling of waste power batteries can promote the sustainable use of resources, reduce environmental pollution, save energy, reduce costs and promote a circular economy. For the recycled power batteries, one of the processing links is to crush them, which requires crushing equipment. The patent with application number CN202221989044.8 discloses a lithium-ion battery crushing and recycling device. The battery crushing and recycling device can better crush lithium-ion batteries and improve the quality of lithium-ion battery crushing through the crushing box, fixed seat, feeding mechanism, base, box door, feed hopper, crushing mechanism, purification mechanism, crushing mechanism, discharge hopper, filter net, first collection box, second collection box and processing control panel. The device still has the following disadvantages. :Lithium-ion batteries are transmitted to the feed hopper through the feeding mechanism, and enter the crushing box through the feeding hopper for crushing. The lithium-ion batteries that enter the crushing box for crushing in this feeding method can only be crushed at one position of the crushing mechanism, that is, the position of the crushing mechanism below the feed hopper. This can easily cause the lithium-ion batteries that enter the crushing box in succession to get stuck in the crushing mechanism and damage the crushing mechanism. If the transmission speed of the feeding mechanism is slowed down to prevent the crushing mechanism from getting stuck, this will greatly reduce the crushing efficiency of the battery. In addition, the rest of the crushing position on the crushing mechanism often does not play the role of crushing the battery, and the crushing mechanism cannot be fully utilized.

DETAILED DESCRIPTION

[0027] The following will be combined with the attached embodiment of the present utility model Figure 1-10 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a technical solution: a waste power battery crushing device, comprising a bottom plate 1, a transmission frame 2 is fixed on the left side of the bottom plate 1, and a crushing mechanism 3 is arranged on the right side thereof, the crushing mechanism 3 comprises a fixed plate 4 movably connected to the bottom plate 1, a plurality of supporting legs 5 are fixed on the fixed plate 4, a crushing box 6 is fixed on the top of the supporting legs 5, a feed hopper 7 is arranged on the top of the crushing box 6, the feed hopper 7 is arranged below the transmission frame 2, and a discharge port 8 is arranged at the bottom of the crushing box 6. When working, the recycled waste power batteries are first placed on the transmission frame 2 one by one, the transmission frame 2 transmits the waste power batteries to the feed hopper 7, the waste power batteries enter the crushing box 6 from the feed hopper 7 for crushing, and the crushed waste power batteries are discharged from the discharge port 8. During the whole crushing process, the crushing mechanism 3 always slides left and right along the bottom plate 1, wherein The right end of the transmission frame 2 extends all the way to the right, leaving enough space for the crushing mechanism 3 to slide to the left. When the crushing mechanism 3 slides to the leftmost side, the left end of the crushing box 6 does not contact the rightmost supporting leg of the transmission frame 2, and the rightmost end of the transmission frame 2 is close to the rightmost end of the feed hopper 7 but does not exceed the rightmost end of the feed hopper 7. When the crushing mechanism 3 slides to the rightmost side, the rightmost end of the transmission frame 2 is close to the leftmost end of the feed hopper 7 and exceeds the leftmost end of the feed hopper 7. During the entire crushing process, the crushing mechanism 3 always moves left and right at a certain speed. This left and right movement process allows the waste power batteries on the transmission frame 2 to evenly enter the crushing box 6 for crushing, and will not be concentrated in one position of the crushing box 6 for crushing. In this way, the waste power batteries can evenly enter the crushing box 6 for crushing, and efficient crushing is achieved while preventing material jamming.

[0029] There are four supporting legs 5, which are respectively fixed at the four corners of the fixed plate 4, and a material receiving frame 9 is provided on the fixed plate 4. This arrangement not only provides good support for the crushing box 6, but also allows a relatively large material receiving frame 9 to be placed under the crushing box 6 to facilitate material receiving.

[0030] The fixed plate 4 is movably connected to the base plate 1 through a screw structure 10. The screw structure 10 includes a first motor 11 fixed to the right end of the base plate 1. A screw 13 is fixed to the first rotating shaft 12 of the first motor 11. The screw 13 is provided with a nut seat 14 matching the screw 13. The fixed plate 4 is fixed to the nut seat 14. The left end of the screw 13 is rotatably connected to a fixed seat 15. The fixed seat 15 is fixed to the base plate 1. The left and right movement of the crushing mechanism 3 is achieved through the screw structure 10.

[0031] The crushing box 6 includes a crushing box body 16, a second motor 17 is fixed on the right side wall of the crushing box body 16, a first connecting shaft 19 extending into the crushing box body 16 is fixed on the second rotating shaft 18 of the second motor 17, a driving gear 20 is fixed on the right end of the first connecting shaft 19, the driving gear 20 is meshed with a driven gear 21, the driven gear 21 is fixed on the second connecting shaft 22, the second connecting shaft 22 extends into the crushing box body 16, and a first crushing roller 23 and a second crushing roller 24 are respectively fixed on the first connecting shaft 19 part and the second connecting shaft 22 part in the crushing box body 16, wherein the left ends of the first connecting shaft 19 and the second connecting shaft 22 are both rotatably connected to the left inner wall of the crushing box 6, and a plurality of crushing blades are fixed on the outer surfaces of the first crushing roller 23 and the second crushing roller 24 to achieve the crushing of the waste power batteries. During specific operation, the second motor 17 is started to drive the first crushing roller 23 and the second crushing roller 24 to rotate towards each other, thereby achieving the crushing of the waste power batteries.

[0032] A pre-crushing mechanism 25 is provided on the transmission frame 2, and the pre-crushing mechanism 25 includes a U-shaped frame 26 fixed on the transmission frame 2, a first cylinder 28 is fixed on the top plate 27 of the U-shaped frame 26, a first telescopic rod 29 of the first cylinder 28 penetrates the top plate 27, and a connecting plate 30 is fixed at the end of the first telescopic rod 29, and a plurality of longitudinal crushing blades 31 are evenly fixed on the connecting plate 30 from left to right, and a blocking mechanism 33 is provided on the front plate 32 of the U-shaped frame 26. Because the waste power batteries are larger in volume than ordinary batteries, the waste power batteries are pre-crushed by the setting of the pre-crushing mechanism 25, so that the crushing effect of the waste power batteries that enter the crushing box 6 for crushing later is better, which further prevents the material from being stuck, and at the same time, it plays a good protective role on the first crushing roller 23 and the second crushing roller 24, thereby increasing their service life. During specific operation, when the waste power battery is transmitted to the U-shaped frame 26, the blocking mechanism 33 will be activated to prevent the waste power battery from moving to the right. At this time, the first cylinder 28 will be activated, so that the longitudinal crushing blade 31 cuts and crushes the waste power battery downward. After the crushing is completed, the longitudinal crushing blade 31 returns to its original position, and the blocking mechanism 33 returns to its original state, so that the pre-crushed waste power battery continues to be transmitted to the right until it is transmitted to the crushing box 6 for crushing.

[0033] The blocking mechanism 33 includes a second cylinder 34 fixed on the front plate 32, and a second telescopic rod 35 of the second cylinder 34 passes through the front plate 32. When the used power batteries are transferred to the U-shaped frame 26, the second cylinder 34 will start, and the second telescopic rod 35 will extend to block the used power batteries. The blocking mechanism 33 has a simple structure and can achieve a good blocking effect.

[0034] A plurality of transverse crushing blades 36 are fixed between adjacent longitudinal crushing blades 31 from front to back. The arrangement of the transverse crushing blades 36 enables a better pre-crushing effect on waste power batteries.

[0035] Working principle: When working, firstly, the recycled used power batteries are placed one by one on the transmission rack 2, and the transmission rack 2 transmits the used power batteries to the feed hopper 7. The used power batteries enter the crushing box 6 from the feed hopper 7 for crushing, and the crushed used power batteries are discharged from the discharge port 8. During the whole crushing process, the crushing mechanism 3 always slides left and right along the bottom plate 1, and the right end of the transmission rack 2 extends to the right, leaving enough space for the crushing mechanism 3 to slide to the left. When the crushing mechanism 3 slides to the leftmost side, the left end of the crushing box 6 does not contact the rightmost supporting leg of the transmission rack 2, and the rightmost supporting leg of the transmission rack 2 is not in contact with the leftmost supporting leg of the transmission rack 2. The right end of the transmission frame 2 is close to the rightmost end of the feed hopper 7 but does not exceed the rightmost end of the feed hopper 7. When the crushing mechanism 3 slides to the rightmost end, the rightmost end of the transmission frame 2 is close to the leftmost end of the feed hopper 7 and exceeds the leftmost end of the feed hopper 7. During the entire crushing process, the crushing mechanism 3 always moves left and right at a certain speed. This left and right movement process allows the waste power batteries on the transmission frame 2 to evenly enter the crushing box 6 for crushing, and will not be concentrated in one position of the crushing box 6 for crushing. In this way, the waste power batteries can evenly enter the crushing box 6 for crushing, thereby achieving efficient crushing while preventing material jamming.
