Description

Technical Field

[0001] The invention relates to the field of transportation, and in particular to a conveying line and a conveying method based on battery unpacking, material separation and drying. Background Art

[0002] The main purpose of lithium battery recycling is to extract valuable metals in the battery, such as lithium, cobalt, nickel, etc. These metals are widely used in new energy vehicles and portable electronic devices. Through recycling, we can reduce dependence on primary mineral resources and reduce environmental pollution during mining and refining.

[0003] During the battery recycling process, the batteries need to be discharged, disassembled and classified to ensure that the batteries are handled under safe conditions. The physical separation stage involves the use of mechanical equipment to crush the disassembled batteries to reduce the particle size for further separation. Conductive materials such as copper and aluminum can be separated from non-metallic materials through vibrating screens, wind sorting and other methods. Magnetic separation is used to separate materials with strong magnetism, such as steel shells. The crushed lithium battery particles are transmitted to the next process through a conveyor line. When the battery contains electrolyte, the electrolyte will affect the next step of recycling, and the battery needs to be dried. The battery will contain electrolyte during use, and these electrolytes will be released during the crushing process. Drying can effectively remove these electrolytes because the electrolyte is a flammable and volatile liquid. If it is not removed, it will increase the safety risks during the processing process, such as fire or explosion.

[0004] Chinese patent application CN107352270A discloses a battery steel shell drying discharge conveyor belt blowing device, including a discharge conveyor belt, on the bases on both sides of the discharge conveyor belt, a door-shaped bracket is installed above the conveyor belt every 60 to 100 cm, and a blower is installed on each door-shaped bracket in an inclined direction toward the material incoming direction of the upper surface of the conveyor belt, and the inclination angle of each blower is 45 to 60 degrees downward from the horizontal, which can quickly cool the material during the discharge process, and has the advantages of shortening the conveying distance and reducing the investment cost;

[0005] Chinese patent application CN104370053A discloses a new type of conveyor belt for washed batteries. A drying room is provided to dry the water of the washed batteries, which is convenient for the assembly of the next process. A water drop collection box is provided to collect and utilize the water flowing down the conveyor belt, which prevents the damp ground from affecting the working environment. A guide rod is provided so that the batteries on the conveyor belt can be transported in an orderly manner to ensure efficient and stable transportation. A steering device and an infrared sensor are provided, and when the infrared sensor senses the batteries on the conveyor belt, the motor will drive the turntable to rotate 90° to move the batteries to the assembly line. A mobile transport vehicle and a welding machine are provided to facilitate the welding of all batteries on the assembly line. The structure is simple and the battery transportation effect is more excellent.

[0006] The above patents and prior art also have the following defects:

[0007] The materials are transported by conveyor belts and dried during the transport process. However, the crushed lithium battery particles contain a large amount of electrolyte. Using hot air to dry the particles will cause the electrolyte to produce a large amount of harmful gases, polluting the environment. The continuous transport and drying method using conveyor belts is difficult to seal and cannot perform continuous feeding and unloading.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

At this time, the drying hood 322 and the conveyor belt 1 are sealed. The drying air pump 323 is arranged in the drying hood 322, and the input end of the drying air pump 323 is connected to the outside of the drying hood 322, and the exhaust pipe 324 is connected to the drying hood 322.

[0046] The material is placed on the conveyor belt 1, and the conveyor belt 1 drives the material to move into the drying box 2. The driving belt 311 drives several drying hoods 322 to move in a circular motion, so that the drying hoods 322 are against the conveyor belt 1 and move synchronously with the conveyor belt 1. The drying air pump 323 introduces gas into the drying hood 322 to air-dry the material. The exhaust pipe 324 discharges the harmful gas in the drying hood 322 through the exhaust pipe 324. Then the drying hood 322 continues to move and separates from the conveyor belt 1. The conveyor belt 1 transfers the dried material out.

One end of the telescopic hose 325 is fixedly installed with a fixed head and is connected, and the fixed head is rotatably connected and connected to the exhaust pipe 324. The exhaust manifold 33 is fixed and connected to one end of the telescopic hoses 325 in all the drying units 32 away from the exhaust pipe 324. The output pipe 34 is sleeved on the exhaust manifold 33 and is rotatably connected to the exhaust manifold 33. The rotating unit 35 can drive the exhaust manifold 33 to rotate.

[0049] The harmful gas in the drying hood 322 is discharged into the exhaust pipe 324 through the drying air pump 323, and the harmful gas in multiple exhaust pipes 324 is discharged into the exhaust main pipe 33. The harmful gas in the exhaust main pipe 33 enters the output pipe 34, and the output pipe 34 passes the harmful gas into the exhaust gas purification equipment. The exhaust gas purification equipment is a prior art and will not be described in detail here. The rotating unit 35 drives the exhaust main pipe 33 to rotate, so that the telescopic hose 325 moves with the exhaust pipe 324, and the telescopic hose 325 is telescoped during the movement, so that the exhaust pipe 324 moves with the drying hood 322 and can also be connected to the exhaust main pipe 33 to transmit harmful gases, thereby ensuring the gas exhaust efficiency during the movement of the drying box 2 and preventing the exhaust pipe 324 and the telescopic hose 325 from being excessively twisted.

[0051] The drying air pump 323 draws the gas outside the drying hood 322 into the heating box 321, and the heating wire 326 heats the gas in the heating box 321. The hot air in the heating box 321 enters the drying hood 322 to dry the material in the drying hood 322. The airflow and harmful gases enter the exhaust pipe 324 through the filter plate 327 and are discharged. The materials are blocked by the filter plate 327 until the materials in the drying hood 322 are dried and no more harmful gases evaporate. The drying hood 322 moves and loses contact with the conveyor belt 1.

The stirring blade 320 stirs the material in the drying box 2 to increase the contact area between the material and the hot air, thereby improving the drying efficiency. At the same time, the stirring blade 320 scrapes the material on the filter plate 327 to prevent the material from always contacting the filter plate 327 under the action of the airflow, thereby improving the gas passing efficiency of the filter plate 327.

[0054] Example 5, reference Figure 1-Figure 9 , which is different from the above-mentioned embodiment, the drying unit 32 also includes a fixed block, one end of the exhaust pipe 324 away from the telescopic hose 325 is rotatably connected to the fixed block, an annular movable hole is opened on the side wall of the drying box 2, the fixed block passes through the annular movable hole and is fixedly installed on the driving belt 311, and a rolling block is rotatably connected to the fixed block, and the rolling block is arranged in the annular movable hole.

[0055] The driving belt 311 drives the fixed block to move, the fixed block drives the exhaust pipe 324 to move, the exhaust pipe 324 drives the drying box 2 to move, and at the same time the fixed block moves in the annular moving hole through the rolling block, so the movement is smoother and not easy to get stuck.

[0056] Example 6, reference Figure 1-Figure 9 , which is different from the above-mentioned embodiment, the driving unit 31 also includes a driving motor 312 and two driving disks.
