Description

Technical Field

[0001] The utility model relates to the field of lithium battery recycling, in particular to environmentally friendly processing equipment for recycling waste lithium batteries. Background Art

[0002] The discharge of waste lithium batteries has brought serious harm to the environment. The harmful substances contained in them, such as cadmium, lead, mercury, etc., not only pollute the soil and water bodies, but also directly endanger human health and life safety. Therefore, the recycling of waste lithium batteries can reduce pollution to the environment. At the same time, it can also be used for the utilization of renewable resources and reduce the consumption of raw material resources. At present, after collecting waste lithium batteries, they need to be crushed first to facilitate the separation of various raw materials.

[0003] At present, when using a crusher to crush waste lithium batteries, the waste lithium batteries are usually directly put into the crusher. However, dust will be generated in the crushing process, and the dust particles will be discharged into the environment, causing air pollution and soil pollution, and having a negative impact on the ecological environment. In addition, dust particles will accumulate and settle around the equipment, making it difficult to clean up, thereby increasing workload and maintenance costs; therefore, a waste lithium battery recycling and environmentally friendly processing equipment is proposed to address the above problems.

[0024] The following is combined with Figure 1-5 To further explain this application in detail,

[0025] The present application embodiment discloses an environmentally friendly waste lithium battery recycling and treatment device. Figure 1 , a waste lithium battery recycling and environmental protection treatment equipment, comprising a pulverizer 1; a fixed plate 2 is fixedly installed on the top of the pulverizer 1, a dust collection component 3 is arranged on the top of the fixed plate 2, and an acceleration feeding component 4 is arranged on both sides of the top of the pulverizer 1;

[0026] Reference Figure 2-Figure 3 The dust collecting assembly 3 includes two conveying pipes 31 fixedly installed on the left and right sides of the top of the fixed plate 2. The bottom end of the conveying pipe 31 passes through the fixed plate 2 and extends to the bottom of the fixed plate 2. The conveying pipe 31 is connected to the crusher 1. When the crusher 1 crushes the battery, the dust particles will enter the conveying pipe 31. A feeding pipe 32 is fixedly installed on the side of the two conveying pipes 31 close to each other. A collecting pipe 33 is fixedly installed on the end of the feeding pipe 32 away from the conveying pipe 31. The two ends of the feeding pipe 32 are respectively connected to the conveying pipe 31 and the collecting pipe 33. The horizontal height of the feeding pipe 32 gradually decreases from the conveying pipe 31 toward the collecting pipe 33, and the dust entering the conveying pipe 31 is discharged. Under the action of gravity, the dust can slide from the feeding pipe 32 to the inside of the collecting pipe 33 and be collected. A motor 34 is fixedly installed at the top of the conveying pipe 31, and a driving rod 35 is fixedly installed on the output shaft at the bottom of the motor 34. A hollow rotating plate 36 is fixedly installed on the surface of the bottom end of the driving rod 35. An isolation plate 37 is clamped inside the conveying pipe 31. Guide pipes 38 are fixedly installed on the front and rear sides of the top of the conveying pipe 31, and a bag collector 39 is fixedly installed on the top of the guide pipe 38. The hollow rotating plate 36 is located below the isolation plate 37. The guide pipes 38 are respectively connected to the conveying pipe 31 and the bag collector 39. The dust inside the conveying pipe 31 is collected inside the bag collector 39 through the guide pipe 38.

[0027] Reference Figure 3-Figure 5 The accelerating feeding assembly 4 includes two transmission plates 41 slidably connected to the left and right sides of the top of the crusher 1. Slide grooves are provided at both the front and rear ends of the transmission plate 41. The transmission plate 41 is slidably connected to the top of the crusher 1 in the vertical direction. The transmission plate 41 can move on the top of the crusher 1. At this time, the vibration of the transmission plate 41 itself will accelerate the efficiency of transporting the battery to the inside of the crusher 1. Support rods 42 are fixedly installed on the left and right sides of the crusher 1. A motor 43 is fixedly installed inside the support rod 42 away from the end of the crusher 1. The output shaft of the motor 43 is fixedly installed with an eccentric wheel 44, support wheels 45 are fixedly installed on the end faces on the left and right sides of the crusher 1, and a sliding rod 46 is slidably connected to the inside of the support wheel 45 away from the crusher 1. A return spring 47 is fixedly installed on the surface of the sliding rod 46. The bottom end of the sliding rod 46 is in adaptive contact with the eccentric wheel 44, and the top end of the sliding rod 46 is in adaptive contact with the bottom end of the transmission plate 41. The end of the return spring 47 away from the sliding rod 46 is fixedly installed on the surface of the support wheel 45. When the eccentric wheel 44 rotates, it will periodically push the sliding rod 46, and at this time, the sliding rod 46 will push the transmission plate 41 to vibrate up and down.

[0028] Working principle: the operator connects the transmission plate 41 to the conveyor belt, and then places the waste batteries on the surface of the conveyor belt and transports them to the surface of the transmission plate 41. At this time, the batteries move to the surface of the transmission plate 41 and then move to the top of the transmission plate 41 under the action of inertia, and then slide to the inside of the crusher 1 under the action of gravity. Then the operator drives the crusher 1 to crush the waste batteries that fall inside, and at this time the operator can drive the motor 43 to drive the eccentric wheel 44 to rotate. Since the eccentric wheel 44 is eccentrically installed on the output shaft of the motor 43, the eccentric wheel 44 will periodically push the sliding rod 46 upward. When the sliding rod 46 is pushed upward, it will push the transmission plate 41 upward inside the support wheel 45 and stretch the reset spring 47. Then the eccentric wheel 44 continues to rotate away from the sliding rod 46, so that the sliding rod 46 moves downward under the action of the rebound force of the reset spring 47. At this time, the transmission plate 41 moves downward under the action of gravity, so that the transmission plate 41 vibrates back and forth, thereby accelerating the batteries to fall into the crusher 1 for crushing.

[0029] After that, the operator drives the bag collector 39. At this time, the bag collector 39 will generate wind force and guide the gas inside the crusher 1 and the conveying pipe 31. At this time, the guided gas will drive the dust particles generated in the crushing process to overcome gravity and move upward to the inside of the conveying pipe 31. At the same time, the driving motor 34 drives the hollow rotating plate 36 to rotate. At this time, the dust particles entering the conveying pipe 31 will contact the rotating hollow rotating plate 36. At this time, under the action of the centrifugal force of the hollow rotating plate 36, the dust particles with larger volume and heavier mass approach the inner wall of the conveying pipe 31 under the action of centrifugal force. Then, the dust particles with larger mass enter the collection pipe 33 through the feeding pipe 32 and are collected. Then, the dust particles with smaller mass will be guided to the inside of the guide pipe 38 under the action of wind force, and then enter the inside of the bag collector 39 and be collected, thereby completing the collection of dust particles.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
