Description

Technical Field

[0001] The invention relates to the technical field of battery electronic device recycling, in particular to a recycling and processing device and method for waste battery electronic devices. Background Art

[0002] Conventional electronic device destruction machines often destroy electronic devices without batteries, such as USB flash drives, hard drives, etc., by knocking, crushing, pulverizing or grinding the devices. However, if electronic devices with batteries are placed in such destruction machines, they will catch fire or even explode at high temperatures due to the chemical properties of the batteries, posing a high risk to personal and property safety. Therefore, conventional electronic device destruction machines cannot be used to destroy electronic devices with batteries.

[0003] In the existing electronic equipment destruction device, during the destruction process, the movement and crushing control of electronic equipment often adopts the remote control and on-site control (alternative) methods in the central control room. The judgment of the material reaching the target position, the material change position and the cutting point is generally based on the installation of proximity switches at each key position on the operating table. The remote control room uses the position signals of several points provided by it to make judgments; after switching to local mode, the most direct control is to use button control. However, the signal switches used in the above methods occasionally fail to work or slip, which poses a safety hazard. Summary of the invention

[0004] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions.

[0006] A lifting mechanism that can be raised and lowered is installed on the conveying mechanism. A placing basket for placing waste battery electronic devices is arranged on the lifting mechanism. The outer wall of the placing basket is composed of a plurality of blocking rods arranged at intervals. An electric door is arranged at the bottom of the placing basket.

[0007] Preferably, the refrigerated gas tank delivers refrigerated gas to the low-temperature cooling box through a pipeline, a liquid level sensor is provided in the low-temperature cooling box, and an automatic filling valve is provided on the pipeline.

[0008] Preferably, a motor cover is provided on the top of the pulverizer.

[0009] Preferably, a door body is hingedly connected to one side of the placing basket located at the material inlet.

[0010] Preferably, the conveying mechanism is a conveyor belt, which is connected to the lifting mechanism through a fixing assembly, and the fixing assembly includes an upper fixing plate and a lower fixing plate located on the upper and lower sides of the conveyor belt, and positioning plates are respectively connected to both ends of the upper fixing plate, and a positioning groove corresponding to the positioning plate is provided on the upper surface of the lower fixing plate, and fixing bolts are respectively provided on the outer side of the positioning plate on the upper fixing plate, and the upper fixing plate and the lower fixing plate are fastened together by fixing bolts.

[0011] Preferably, a level sensor is provided on the hoisting mechanism.

[0012] Preferably, an automatic control device is provided above the conveying mechanism in the processing chamber, and the automatic control device is electrically connected to the level sensor, the liquid level sensor, the conveying mechanism, the lifting mechanism, the electric door, the motor cover, and the automatic filling valve.

[0013] A method for recycling waste battery electronic devices comprises the following steps:

[0014] S1, open the door of the placement basket through the material inlet on the processing chamber, put the waste battery electronic devices to be destroyed into the placement basket, and close the door;

[0015] S2, the automatic control device controls the conveying mechanism to convey the placing basket to the top of the low-temperature cooling box, and controls the lifting mechanism to drive the placing basket to move downward until the placing basket is immersed in the refrigeration gas of the low-temperature cooling box and remains stationary for 1-10 minutes;

[0016] S3, after the immersion is completed, the automatic control device controls the lifting mechanism to drive the placement basket to move upward until the placement basket rises to the top of the low-temperature cooling box;

[0017] S4, the conveying mechanism and the lifting mechanism drive the placing basket to continue to move backwards. When it moves to the top of the crusher, the automatic control device controls the motor cover and the electric door to open in sequence, and the battery electronic devices in the placing basket fall into the crusher;

[0018] S5, after the crushing is completed, the crushed material is taken out from the powder outlet through the material outlet of the processing chamber.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention effectively avoids the risk of explosion during the destruction of battery electronic devices and the risk to personal safety caused by the low temperature of the refrigerant gas through an automatic control device and a low-temperature cooling box. The immersion cooling gas technology is mainly adopted. The immersion liquid completely covers the entire electronic product surface of the battery module, which can achieve a more uniform heat distribution and reduce the occurrence of local hot spots. By utilizing the rapid evaporation of the refrigerant gas in the immersion liquid, the entire electronic product including the battery can be reduced to an ultra-low temperature of minus 200 degrees more quickly. Compared with air cooling and other traditional cooling methods, it consumes less additional energy and resources, and is relatively energy-saving and environmentally friendly. At the same time, electronic products with batteries can be input into the system as a whole without the need to disassemble the batteries separately. The metal crushing process is fully automated, which saves more labor and reduces the risk of low-temperature frostbite and explosion for operators.

[0021] 2. The automatic control device of the present invention can accurately control the entire processing flow, including the steps of moving, freezing, and crushing materials, thereby reducing manual operations and improving work efficiency and processing accuracy.

[0022] 3. The processing chamber of the present invention is integrated in design, and the layout of various components is reasonable, such as the design of the liftable hoisting mechanism and the barrier rods arranged at intervals, which not only ensures the compactness of the equipment, but also facilitates daily inspection and maintenance.

[0023] In summary, the recycling and processing equipment and method not only improve the environmental friendliness and efficiency of the processing of waste battery electronic devices, but also reduce operating costs through highly automated and intelligent design, and have significant social and economic benefits.
