Description

Technical Field

[0001] This utility model belongs to the field of transfer technology, specifically relating to a waste circuit board recycling and transfer device. Background Technology

[0002] Metals such as aluminum, lead, zinc, nickel, and tin are widely found in circuit boards. After recycling, they can be used in electrical equipment manufacturing or as industrial raw materials. Recycling reduces the accumulation of electronic waste and prevents heavy metals (such as lead and mercury) and harmful substances from polluting soil and water sources.36 Resource regeneration alleviates the pressure on mineral extraction; for example, the copper recovered from one ton of waste circuit boards is equivalent to the output of mining 30 tons of copper ore. The core value of circuit board recycling lies in the comprehensive recycling and utilization of precious metals, common metals, plastics, and electronic components, offering significant economic and environmental benefits. Through refined classification and technical processing (such as dismantling, sorting, and refining), efficient resource recycling can be achieved while reducing environmental risks. Because different metals (such as gold, silver, copper, and palladium) have significantly different chemical properties and recycling processes, they need to be sorted and refined separately according to category. When circuit boards are transferred from one process to another, transfer equipment is required for their transport.

[0003] A search revealed Chinese patent CN221852812U, which discloses a transfer device for recycling waste circuit boards. The device includes a transfer box with a handle on top and multiple locking devices inside. A hinged door is mounted on the side of the box, which uses a compression spring to limit the circuit board's position. This device can accommodate circuit boards of different sizes and widths. However, in actual use, different metals require different solutions for stripping and extraction. Therefore, after removing the circuit board from the solution, water is needed to rinse the surface. The residual water on the circuit board surface may dilute the concentration of the solution in the next process, thus reducing the efficiency of metal stripping. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a waste circuit board recycling and transfer device, including a transfer vehicle shell 1. The interior of the transfer vehicle shell 1 is provided with a draining component 2 for filtering out water. The surface of the transfer vehicle shell 1 is provided with a ventilation component 3 for absorbing harmful gases. The surface of the transfer vehicle shell 1 is provided with a liquid storage and discharge component 4 for discharging waste liquid. The draining component 2 includes a synchronous belt 21 disposed inside the transfer vehicle shell 1. The synchronous belt 21 is slidably connected to the transfer vehicle shell 1. The interior of the synchronous belt 21 is evenly provided with a plurality of holes. The surface of the transfer vehicle shell 1 is provided with a moving mechanism for rotating the synchronous belt 21, thereby realizing the separation of circuit boards from liquid, so that the dissolution efficiency is not affected when proceeding to the next process.

[0022] In this embodiment, the moving mechanism includes two fixed shells 22 symmetrically fixed to the surface of the transfer car body 1 by bolts, and both fixed shells 22 are interconnected with the interior of the transfer car body 1. Each fixed shell 22 is rotatably connected to a synchronous pulley, and the two ends of the synchronous belt 21 are respectively inserted into the interior of the two fixed shells 22 and fitted onto the surface of the synchronous pulley and meshing with it. A motor 23 is installed on the surface of one of the fixed shells 22, and the output shaft of the motor 23 passes through the surface of the fixed shell 22 and is fixedly connected to the synchronous pulley. The interior of the transfer car body 1 is also provided with a cleaning mechanism for cleaning the surface of the synchronous belt 21, so that the circuit board will tumble inside the transfer car body 1. When tumbling and shaking, the gap between the circuit boards will change, thereby facilitating the liquid to fall and accelerating the drainage effect.

[0023] In this embodiment, two first brush plates 24 are symmetrically fixedly connected to the inner wall of the transfer vehicle shell 1. The two first brush plates 24 are respectively located on the inner wall of the timing belt 21, and the brush surface of the first brush plate 24 is in contact with the inner wall of the timing belt 21. A plurality of second brush plates 25 are uniformly fixedly connected to the inner wall of the transfer vehicle shell 1, and the brush surface of each second brush plate 25 is in contact with the outer surface of the timing belt 21 to prevent liquid from contacting the timing wheel and thus corroding the timing wheel, thereby causing damage to the timing wheel.

[0024] In this embodiment, the ventilation assembly 3 includes two fans 31 installed on the surface of the transfer car body 1. The two fans 31 are staggered, and air ducts 32 are installed on the side of the two fans 31 away from the transfer car body 1. The end of the air duct 32 away from the fans 31 is inserted into the interior of the transfer car body 1, and the end of the air duct 32 inserted into the interior of the transfer car body 1 is located below the synchronous belt 21. This is to prevent harmful gases from the evaporation of the residual solution on the circuit board surface from being inhaled and causing harm to the human body.

[0025] In this embodiment, the liquid storage and drainage assembly 4 includes a drain pipe 42 installed on the surface of the transport vehicle shell 1, a water inlet pipe 43 installed on the side of the transport vehicle shell 1 away from the drain pipe 42, and a gathering plate 41 symmetrically fixedly connected inside the transport vehicle shell 1, which realizes the capture of harmful gases and residual liquids.

[0026] The use of this utility model involves the following steps:

[0027] S1: Water is pumped into the interior of the transfer car body 1 through the inlet pipe 43 by an external water pump until a certain amount of water is reached. Only then can the circuit board be placed inside the transfer car body 1 for transfer. Because the liquid remaining on the surface of the circuit board contains a solution, most of which is soluble in water, the liquid that is not rinsed off falls into the lower layer of the transfer car body 1 and is diluted again by the water inside. The solution that is not soluble in water will sink to the bottom. Because there is little residue on the surface of the circuit board, the solution in the water will not be saturated. When it is necessary to drain, the valve of the drain pipe 42 is opened and the water inside the transfer car body 1 will be drained. The gathering plate 41 can gather the water towards the drain pipe 42 to prevent residue.

[0028] S2: After the circuit board is removed from the solution, water is needed to rinse the solution on the surface of the circuit board. The water remaining on the surface of the circuit board may dilute the concentration of the solution in the next process. Therefore, after the circuit board is placed inside the transfer car body 1, the circuit board will be piled on the surface of the synchronous belt 21. The liquid remaining on the surface of the circuit board will fall into the interior of the transfer car body 1 through the holes opened on the surface of the synchronous belt 21 due to gravity.

[0029] S3: Because the circuit boards are stacked inside the transfer car body 1, in order to speed up the drainage effect, the motor 23 is first connected to the external power supply and then started. The synchronous pulley will drive the synchronous belt 21 to rotate inside the transfer car body 1. The circuit boards placed on the surface of the synchronous belt 21 will be moved by friction.

[0030] S4: When the timing belt 21 is rotating, the first brush plate 24 and the second brush plate 25 work together to scrape off the liquid remaining on the inner and outer surfaces of the timing belt 21.

[0031] S5: When the circuit board is placed inside the transfer car body 1, the fan 31 is connected to an external power source and started. The fan 31 will draw air from inside the transfer car body 1 into the air duct 32, and then discharge it into the transfer car body 1 through the air duct 32. The end of the air duct 32 away from the fan 31 is also located at the bottom of the water. The harmful gas will dissolve in the water or sink to the bottom.

[0032] S6: When it is necessary to clean the inside of the transfer car body 1, open the drain pipe 42 and pour water directly into the inside of the transfer car body 1. This can clean the solution on the inner wall of the transfer car body 1 and increase the service life of the transfer car body 1.

[0033] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
