Description

Technical Field

[0001] This utility model relates to the field of rare and precious metal recycling technology, and more specifically to a rare and precious metal recycling feeding device. Background Technology

[0002] Rare and precious metals are a collective term for rare and precious metals. They are difficult to extract from raw materials and their industrial preparation and application started relatively late.

[0003] For example, a waste communication circuit board recycling device disclosed in announcement number CN215657024U involves a reaction between the communication circuit board and chemical reagents. The metal in the communication circuit board is not dissolved, but the remaining substances dissolve in the chemical reagents, allowing for rapid recycling of the communication circuit board and saving manpower. However, when the crushed circuit board is fed back into the system, the feeding of the circuit board will cause liquid to splash. The reagents used to dissolve circuit boards are generally corrosive, and the splashed solution can easily fall on the workers, causing injury. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rare and precious metal recycling and feeding device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a rare and precious metal recycling feeding device, including a tank body, an inlet on one side of the tank body, an inner tube rotatably connected to the inner wall of the top of the tank body, two spiral plates fixed to the outer circumference of the inner tube by bolts, and the spiral plates contacting the inner circumference of the tank body, a power mechanism for driving the inner tube to rotate is provided at the top of the tank body, and a feed pipe connected to the inlet is fixed to the outer wall of one side of the tank body by bolts, and a discharge mechanism for assisting material feeding is provided in the feed pipe.

[0006] As a further embodiment of this utility model, the power mechanism includes a motor that is fixed to the outer wall of the top of the tank by bolts, the output shaft of the motor is connected to a gear through the tank by a key, and a gear ring that meshes with the gear is fixed to the top of the inner wall of the inner tube by bolts.

[0007] As a further embodiment of this utility model, the discharge mechanism includes a clearance groove formed on the inner wall of the bottom of the feed pipe, a slide frame slidably connected in the clearance groove, and a spring fixed to the bottom of the slide frame by bolts, and the spring is fixed to the clearance groove.

[0008] As a further embodiment of this utility model, one end of the slide is welded with a limit ring through the feed pipe so that the top of the slide does not exceed the clearance groove.

[0009] As a further embodiment of this utility model, a vibration motor is fixed to the bottom outer wall of the feed pipe by bolts, and the vibration motor is located directly below the slide.

[0010] As a further embodiment of this utility model, the inner circumference of the tank is fixed with a partition by bolts, and the top of the partition has multiple evenly distributed discharge ports.

[0011] As a further embodiment of this utility model, an inverted cone plate is fixed to the inner circumference of the tank body by bolts, and the inverted cone plate is located below the partition plate.

[0012] As a further embodiment of this utility model, the bottom end of the inner wall of the inner tube is fixed with multiple stirring racks by bolts, and the lengths of the multiple stirring racks are different.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model has an inner tube and a spiral plate.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-3 This utility model provides a rare and precious metal recycling feeding device, including a tank body 1. A feed inlet 8 is provided on one side of the tank body 1. An inner tube 4 is rotatably connected to the inner wall of the top of the tank body 1. Two spiral plates 7 are fixed to the outer circumference of the inner tube 4 by bolts, and the spiral plates 7 are in contact with the inner circumference of the tank body 1. A power mechanism is provided at the top of the tank body 1 to drive the inner tube 4 to rotate. A feed pipe 3 connected to the feed inlet 8 is fixed to the outer wall of one side of the tank body 1 by bolts. A discharge mechanism is provided in the feed pipe 3 to assist in feeding. In use, the crushed material is placed in the feed pipe 3. The discharge mechanism conveys the material to the interlayer between the inner tube 4 and the tank body 1, where it is blocked by the spiral plates 7. The power mechanism drives the inner tube 4 to rotate, thereby driving the spiral plates 7 to rotate, so that the material is evenly discharged from the interlayer, and the material is evenly dispersed around the bottom of the tank body 1, reducing the height of the material's free fall, thereby avoiding the speed at which the material comes into contact with the solution, and preventing the material from splashing out from the feed inlet 8, thus improving the protective effect of the device.

[0023] Furthermore, the power mechanism includes a motor 2 fixed to the top outer wall of the tank 1 by bolts. The output shaft of the motor 2 is keyed to a gear 5 through the tank 1. The top of the inner circumference of the inner tube 4 is fixed with a gear ring 6 that meshes with the gear 5 by bolts. When the motor 2 is started, the motor 2 drives the gear 5 to rotate, which in turn drives the gear ring 6 to rotate, and then drives the inner tube 4 and the spiral plate 7 to rotate, thereby realizing the dispersion and conveying of materials. The gear 5 and the gear ring 6 are decelerating motions, which reduces the rotational speed of the inner tube 4 and the spiral plate 7, thereby reducing the impact of centrifugal force on the friction between the inner tube 4, the spiral plate 7 and the tank 1, and improving the service life of the device.

[0024] Furthermore, the discharge mechanism includes a clearance groove 13 formed on the inner wall of the bottom of the feed pipe 3. A slide 15 is slidably connected in the clearance groove 13. A spring 17 is fixed to the bottom of the slide 15 by bolts, and the spring 17 is fixed to the clearance groove 13. A vibration motor 16 is fixed to the outer wall of the bottom of the feed pipe 3 by bolts. The vibration motor 16 is located directly below the slide 15. When the vibration motor 16 is started, it vibrates, causing the spring 17 to reciprocate and contract, thereby causing the slide 15 to slide up and down, thus shaking the material on the slide 15 and causing the material to slide down quickly, preventing the material from getting stuck in the feed pipe 3 and improving the smoothness of the discharge. One end of the slide 15 passes through the feed pipe 3 and is welded with a limit ring 14. The limit ring 14 restricts the movement distance of the slide 15, ensuring that the top of the slide 15 does not exceed the clearance groove 13, thereby preventing the material from falling into the gap between the slide 15 and the clearance groove 13 and improving the protective effect of the device.

[0025] Furthermore, a partition 9 is bolted to the inner circumference of the tank body 1. Multiple evenly distributed discharge ports 10 are opened through the top of the partition 9. The material will fall onto the partition 9 first. The rotation of the spiral plate 7 will push the material through the discharge ports 10. An inverted cone plate 11 is bolted to the inner circumference of the tank body 1. The inverted cone plate 11 is located below the partition 9. The material passing through the discharge ports 10 will be guided by the inverted cone plate 11 to flow towards the center of the tank body 1, so that the material can be dispersed to both sides, further increasing the contact area between the material and the chemical reagent.

[0026] Furthermore, multiple stirring racks 12 are fixed to the bottom of the inner wall of the inner tube 4 by bolts, and the lengths of the multiple stirring racks 12 are different. The rotation of the inner tube 4 will drive the stirring racks 12 to rotate, thereby accelerating the reaction between chemical reagents and materials. The stirring racks 12 of different lengths can stir the solution at different positions.

[0027] The working principle of this utility model is as follows: First, the chemical reagent is placed into the tank 1, ensuring the reagent solution level in the tank 1 does not exceed the bottom of the inner tube 4. Then, the pulverized material is placed in the feed pipe 3. The vibration motor 16 is started to generate vibration, causing the spring 17 to reciprocate, which in turn causes the slide 15 to slide up and down, thus shaking the material on the slide 15. The material quickly slides into the interlayer between the inner tube 4 and the tank 1, where it is blocked by the spiral plate 7. The motor 2 is then started, driving the gear 5 to rotate, which in turn drives the gear ring 6 to rotate, thereby... The rotating inner tube 4 and spiral plate 7 disperse and transport the material. The material first falls onto the partition plate 9. The rotation of the spiral plate 7 pushes the material through the discharge port 10. The material passing through the discharge port 10 is guided by the inverted cone plate 11 and flows towards the center of the tank 1, further reducing the falling speed of the material and the impact force of the material falling into the solution, thus improving the protective effect of the device. At the same time, the material can be dispersed to both sides, so that the material is evenly dispersed around the bottom of the tank 1, thereby expanding the contact area between the material and the chemical reagent and improving the recovery efficiency of rare and precious metals.

[0028] 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. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
