Description

Technical Field

[0001] The utility model relates to the technical field of power battery recycling, in particular to a power battery recycling and processing system. Background Art

[0002] Currently, in the field of power battery recycling, operations are basically carried out on assembly lines within factories to complete tasks such as battery crushing, screening, and transportation. Working in a fixed area certainly has certain advantages, such as spacious venues that facilitate equipment arrangement and centralized control, but its disadvantages are also obvious. First, costs are increased (land costs, management costs), and recycled batteries cannot be processed in a timely manner, requiring additional turnover warehouses for stacking batteries. Second, during the transportation of batteries, due to the residual charge inside the batteries, once squeezed, short circuits or even explosions are likely to occur between the batteries.

[0003] To this end, our company has developed this mobile vehicle-mounted battery recycling and processing device, which can crush, filter, and remove harmful components from batteries. In this process, the residual charge inside the battery can be released, making it less likely to cause short circuits or explosions during subsequent transportation. In addition, the battery fragments that have undergone preliminary processing can be directly transported back to the factory for further processing without the need for stacking and turnover.

[0024] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-2 As shown, the utility model provides a technical solution: a power battery recycling and processing system, including a vehicle body 1, on which a material hoist 2, a crusher 3, a hydraulic filter 7 and a filter press 9 (a horizontal frame filter press is used) are respectively provided.

[0026] The feed port of the crusher 3 is respectively provided with a water inlet pipe 13 and a water inlet pump 14. The water inlet pipe 13 is connected to the external water source. Of course, we can also place a water tank separately inside the carriage, so that we do not have to be subject to the disadvantage of water shortage, and most of the water inside the equipment can be recycled.

[0027] The discharge port of the material hoist 2 is connected to the feed port of the crusher 3. An overflow pipe 31 is provided on the top of the crusher 3. A pure water tank 6 and a circulating water tank 5 are provided below the overflow pipe 31 from top to bottom. The excess water inside the crusher 3 can flow into the pure water tank 6 through the overflow pipe 31. The pure water tank 6 is connected to the circulating water tank 5 through a pipeline. Water level sensors 15 are provided in the pure water tank 6 and the circulating water tank 5. The water level sensor 15 can be used to detect the water level so as to increase the water volume in time.

[0028] A mesh belt conveyor line 4 is provided below the discharge port of the crusher 3. The discharge port of the mesh belt conveyor line 4 is located directly above the feed port of the hydraulic filter 7. The circulating water tank 5 is located below the mesh belt conveyor line 4. A first discharge belt 8 is provided below the discharge port of the hydraulic filter 7. The water receiving trough at the bottom of the hydraulic filter 7 is connected to the circulating water tank 5 through a pipeline.

[0029] The circulating water tank 5 is connected to the filter press 9 through a water pipe 10 and a water pump 11. A second discharge belt 12 is provided at the discharge port at the bottom of the filter press 9. The water outlet of the filter press 9 is connected to the pure water tank 6.

[0030] An air purifier 16 is also provided on the vehicle body 1. The air purifier 16 adopts an RCO catalytic combustion furnace (this is existing technology and can be directly used). The air purifier 16 extends to the interior of the vehicle compartment through a purification pipe 17. There are at least two purification pipes 17, one of which is connected to the feed port of the crusher 3.

[0031] It should be noted that: 1. The material hoist 2, crusher 3 and hydraulic filter 7 in this equipment have been patented separately, so they are not described in detail in this application; 2. A sealing cover is provided on the outside of the vehicle body 1, which is not shown in the figure. The sealing cover is used to prevent harmful components from escaping and polluting the environment.

[0032] At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0033] During use, the battery is transported to the feed port of the crusher 3 through the material hoist 2, and the battery is pushed into the crusher 3. The crusher 3 is connected to the water source through the water inlet pipe 13. The battery is crushed and discharged in the crusher 3, and then the battery fragments fall onto the mesh belt conveyor line 4 below. The solid-liquid separation is carried out through the mesh holes on the mesh belt conveyor line 4. The solid fragments are transported to the hydraulic filter 7, and the liquid flows into the circulating water tank 5 below.

[0034] After the solid crushed material undergoes secondary filtration in the hydraulic filter 7, the solid material is output through the first discharge belt 8 below (the solid material can be stored in a dedicated ton bag and then transported), and the moisture in the crushed material is directly sent to the circulating water tank 5 through the water receiving trough at the bottom of the hydraulic filter 7 for recycling.

[0035] Turn on the water pump 11 to send the sewage in the circulating water tank 5 into the filter press 9. After being filtered by the filter press 9, the solid material is output through the second discharge belt 12 below (the solid material can be stored in a dedicated ton bag and then transported).

[0036] The clean water filtered out from the filter press 9 is sent to the pure water tank 6 for secondary use.

[0037] The purification pipe 17 can absorb and purify harmful components such as dust gas inside the carriage and the crusher 3, and then discharge them harmlessly.

[0038] To sum up, the power battery recycling and processing system is improved based on the existing truck compartment, and the relevant battery processing equipment is reasonably arranged inside the compartment. The recycled batteries can be crushed and filtered through the vehicle-mounted recycling equipment, and the harmful dust and gas generated in the process are also harmlessly treated without causing pollution to the environment. The battery fragments processed by the equipment have had their electric charge removed, so they are less likely to short-circuit or explode during subsequent transportation. At the same time, the battery fragments can be directly put into deep processing after being transported back to the factory, without the need for stacking and turnover.

[0039] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device that controls a computer, etc. Its control principle, internal structure, and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration. In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
