Description

Technical Field

[0001] The utility model relates to the technical field of waste circuit board treatment equipment, in particular to a raw material treatment device for waste circuit boards. Background Art

[0002] Waste circuit boards are mainly used to disassemble and recycle waste electronic products with circuit boards such as waste household appliances and waste computers. Waste circuit boards contain a large amount of heavy metals and other harmful substances, such as lead, mercury, cadmium, etc. If not properly treated, it will cause serious pollution to the environment such as soil and water sources. Through professional recycling and treatment, these harmful substances can be rendered harmless to avoid environmental damage.

[0003] In the prior art, the crushed circuit boards are put into acid solution, and metals and other substances are separated through acid solution immersion and chemical reactions. In this process, the crushed circuit boards to be processed are supported by a stainless steel wire mesh frame and soaked in the acid solution. Subsequently, the metals in the acid solution are treated separately. However, the fixed immersion method is extremely disadvantageous for a large number of stacked crushed circuit boards. The crushed circuit boards are attached to each other or partially not fully immersed, and the acid solution cannot quickly carry out chemical reactions. And when the acid solution is subsequently transported by an existing centrifugal pump or metering pump, since the acid solution has certain corrosiveness, it is not conducive to long-term direct transportation by pump equipment. Therefore, we propose a raw material treatment device for waste circuit boards to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a raw material treatment device for waste circuit boards.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Installation holes are formed in the outer walls of the other L-shaped bracket and the processing frame, and the inner walls of the installation holes are slidably connected with the outer wall of the liquid inlet pipe. By providing the conveying mechanism, there is no need for a conveying device to directly contact the acid solution for conveying, which is beneficial to maintenance.

[0009] Preferably, a circular hole is formed in the outer wall of the processing frame, and the inner wall of the circular hole is rotatably connected with the outer wall of the output shaft of the first motor.

[0014] In this solution, by providing a liquid storage tank, an air pump, a one-way valve and a liquid inlet pipe, the liquid is introduced by increasing the air pressure, without using the direct conveying method, reducing the impact on the conveying equipment;

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1-3 shown, it relates to a raw material processing device for waste circuit boards, including two L-shaped brackets 1. The outer walls of the two L-shaped brackets 1 are respectively rotatably connected with a bushing and a connecting shaft 2. A same processing frame 3 is rotatably connected between the connecting shaft 2 and the bushing. The processing frame 3 rotates through the bushing and the connecting shaft 2, and the processing frame 3 is used to place the crushed circuit boards.

[0023] A heat dissipation frame is fixedly connected to the outer wall of the processing frame 3. A first motor 4 is fixedly connected inside the heat dissipation frame. A circular hole is opened on the outer wall of the processing frame 3, and the inner wall of the circular hole is rotatably connected with the outer wall of the output shaft of the first motor 4. One end of the output shaft of the first motor 4 is fixedly connected with a rotating shaft 5, and two U-shaped stirring rods 6 are fixedly connected to the outer wall of the rotating shaft 5. The rotating shaft 5 and the U-shaped stirring rods 6 are made of stainless steel.

[0024] Inside the processing box 3, a filter plate 7 is fixedly connected. The filter plate 7 supports the crushed circuit boards and prevents the crushed circuit boards from blocking the drain pipe 8 during subsequent liquid drainage. The bottom of the processing box 3 is fixedly interconnected with a drain pipe 8. A valve 9 is fixedly installed on the outer wall of the drain pipe 8. A liquid storage tank 11 is placed on the outer wall of the L-shaped bracket 1. The top of the liquid storage tank 11 is fixedly interconnected with a liquid injection pipe 15. A sealing cover is threadedly sleeved on the top of the liquid injection pipe 15.

[0025] A turning mechanism is provided on the outer wall of the L-shaped bracket 1. The turning mechanism includes a second motor 10. A through hole is formed on the outer wall of one of the L-shaped brackets 1. The inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the second motor 10. A frame body 16 is fixedly connected to the outer wall of one of the L-shaped brackets 1. The inner wall of the frame body 16 is fixedly connected to the outer wall of the second motor 10. One end of the output shaft of the second motor 10 is fixedly connected to the outer wall of the connecting shaft 2. The operation of the second motor 10 drives the processing box 3 to rotate, facilitating the cleaning and collection of the circuit boards inside.

[0026] A conveying mechanism is provided on the top of the liquid storage tank 11. The conveying mechanism includes an air pump 12. The top of the liquid storage tank 11 is fixedly connected to the outer wall of the air pump 12. The output end of the air pump 12 penetrates the top of the liquid storage tank 11, and the penetration position is sealed. A one-way valve 13 is fixedly installed on the outer wall of the output end of the air pump 12. The one-way valve 13 prevents the air pressure in the liquid storage tank 11 from flowing back. The air pump 12 increases the pressure, causing the acid solution to be pressurized. The acid solution overcomes gravity and friction and flows out through the liquid inlet pipe 14. An assembly hole is formed on the outer wall of the liquid storage tank 11. The inner wall of the assembly hole is fixedly connected to the liquid inlet pipe 14. A sleeve is sleeved on the outer wall of the liquid inlet pipe 14. Installation holes are formed on the outer walls of the other L-shaped bracket 1 and the processing box 3. The inner walls of the installation holes are slidably connected to the outer wall of the liquid inlet pipe 14.

[0027] Working principle: When in use, place the crushed circuit boards into the liquid storage tank 11 and on the filter plate 7. The air pump 12 operates to convey the outside air through the output end and the one-way valve 13 into the liquid storage tank 11, increasing the air pressure in the liquid storage tank 11. The acid solution flows along the liquid inlet pipe 14 into the processing box 3. In this process, the liquid is fed by increasing the air pressure, eliminating the need for direct conveyance and reducing the impact on the conveying equipment. After the acid solution enters the processing box 3, the first motor 4 operates to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the two U-shaped stirring rods 6 to rotate, dispersing the crushed circuit boards for better contact with the acid solution. At the same time, after the processing is completed, open the valve 9 to discharge the mixed liquid. After the discharge is complete, the second motor 10 operates to drive the connecting shaft 2 to rotate, causing the processing box 3 to rotate through the connecting shaft 2 and the sleeve, making it tilt, facilitating the cleaning and collection of the circuit boards inside for subsequent processing.
