Description

Technical Field

[0001] The present invention relates to the technical field of battery waste treatment, and in particular to an environmentally friendly treatment device and method for waste in a battery preparation process. Background Art

[0002] Solid-state batteries are batteries that use solid electrodes and solid electrolytes. The battery waste generated during the preparation process may include various precious metal materials, which need to be recycled. At present, the recycling process of solid-state battery waste mainly uses sulfuric acid digestion - water immersion - impurity removal - extraction - oxalic acid precipitation and calcination for recovery.

[0003] Currently, in the sulfuric acid digestion process, solid-state battery waste and sulfuric acid are added to the reaction tank at one time, which results in uneven contact between the solid-state battery waste and sulfuric acid. It takes a lot of time for the two to fully react, and during the reaction, the reaction temperature is generally controlled at 50-100°C. The reaction between solid-state battery waste and sulfuric acid is exothermic. So when solid-state battery waste and sulfuric acid are added to the reaction tank at one time, if a violent reaction occurs and the temperature rises rapidly, it cannot be rescued in time, which easily leads to a low digestion rate of precious metal materials.

[0017] An environmentally friendly method for treating waste materials in a battery manufacturing process comprises the following steps:

[0018] S1. Put sulfuric acid in a liquid storage barrel and put the crushed electrolyte waste in a storage barrel;

[0019] S2, the driving motor rotates, and drives the three acid leaching boxes to rotate through the first rod, the cylinder and the three fixed plates, so that the three hard tubes drive the first ring to rotate, and at this time, sulfuric acid and electrolyte waste will intermittently fall into the acid leaching box for reaction;

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. A processing mechanism is set up, sulfuric acid enters the liquid inlet chamber through the liquid inlet pipe, and the electrolyte waste enters the feed chamber through the feed pipe.

After the first solenoid valve is powered on and closed, the refrigeration frame can pump the cold air inside into the second annular groove through the one-way air outlet pipe. Then the cold air will flow out from multiple air outlets through the hollow rod opened by the second solenoid valve. Cold air is pumped into the acid immersion box to cool the inside of it, thereby avoiding the phenomenon in the prior art that if a violent reaction occurs and the temperature rises rapidly, it is easy to cause a low digestion rate of precious metal materials.

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1 - Figure 8 An environmentally friendly treatment device for waste materials in a battery preparation process comprises a treatment tank 1, a liquid storage barrel 2 and a material storage barrel 3 are fixedly connected to the upper end of the treatment tank 1, and a circular groove 4 is opened at the bottom of the treatment tank 1.

[0037] The processing mechanism includes three acid leaching boxes 5. A feed barrel 6 is fixedly connected to the upper inner wall of the processing tank 1 through a bracket. The feed barrel 6 opens downward. A partition 7 is fixedly connected to the top of the feed barrel 6. Inclined plates 8 are fixedly connected between the side walls on both sides of the partition 7 and the inner wall of the feed barrel 6. The partition 7 and the two inclined plates 8 divide the feed barrel 6 into a liquid inlet chamber 9 and a feed chamber 10. The bottom of the liquid storage barrel 2 is connected to the inner wall of the liquid inlet chamber 9 through a liquid inlet pipe 45. The bottom of the storage barrel 3 is connected to the inner wall of the feed chamber 10 through a feed pipe 46. A first annular groove is provided below the side wall of the feed barrel 6. A first ring 11 that can rotate is sealingly and slidably connected to the inner wall of the first annular groove. An opening 12 (such as Figure 3 As shown), the tops of the three acid immersion boxes 5 are fixedly connected with hard pipes 13 connected to the inner wall of the first ring 11. When the first ring 11 rotates, the hard pipe 13 faces the opening 12, and a first electric butterfly valve (not shown in the figure) is installed in the hard pipe 13.

The side wall of the partition 7 is rotatably connected to a first rod 16, and the lower end of the first rod 16 is fixedly connected to the upper end of the cylinder 14. The upper end of the processing tank 1 is fixedly connected to a motor 17 through an L-shaped plate, and the movable end of the motor 17 is fixedly connected to the upper end of the first rod 16.

[0039] An exhaust port 22 is provided at the top of the acid immersion box 5 , and a discharge pipe 23 is fixedly connected to the bottom of the acid immersion box 5 . A second electric butterfly valve is installed in the discharge pipe 23 .

[0040] Furthermore, sulfuric acid is placed in the liquid storage barrel 2, and the crushed electrolyte waste is placed in the storage barrel 3. At this time, sulfuric acid will enter the liquid inlet chamber 9 through the liquid inlet pipe 45, and the electrolyte waste will enter the feed chamber 10 through the feed pipe 46. When the motor 17 rotates, the three acid leaching boxes 5 are driven to rotate through the first rod 16, the cylinder 14 and the three fixed plates 15, so that the three hard tubes 13 drive the first ring 11 to rotate, so that the three hard tubes 13 intermittently correspond to the openings 12 located in the liquid inlet chamber 9 and the feed chamber 10, so that sulfuric acid and electrolyte waste will intermittently fall into the acid leaching box 5 for reaction, avoiding the prior art that both solid-state battery waste and sulfuric acid are added to the reaction tank at one time, resulting in uneven contact between the solid-state battery waste and sulfuric acid, and requiring a lot of time to allow the two to fully react. If a violent reaction occurs and the temperature rises rapidly, it cannot be rescued in time, which easily leads to a low digestion rate of precious metal materials.

[0041] The tops of the three acid leaching boxes 5 are rotatably connected to hollow rods 18, and the side walls of the hollow rods 18 located in the acid leaching boxes 5 are fixedly connected to multiple mixing rods 19. The side walls of the three hollow rods 18 all penetrate the upper ends of the acid leaching boxes 5 and are fixedly connected to gears 21. The inner wall of the processing tank 1 is fixedly connected to a gear ring 20 through a bracket, and the side walls of the three gears 21 are meshed with the inner wall of the gear ring 20.

[0042] During the rotation of the three acid leaching tanks 5, the three hollow rods 18 and the three gears 21 are driven to revolve. At this time, the three gears 21 rotate under the action of the gear ring 20, driving the three hollow rods 18 and the plurality of mixing rods 19 to rotate, so as to evenly mix the sulfuric acid and the electrolyte waste in the acid leaching tank 5, thereby accelerating the reaction efficiency of the electrolyte waste.

[0043] The inner wall of the processing tank 1 located above the gear ring 20 is fixedly connected to a fixing ring 24 through a bracket, a second annular groove 25 is provided at the lower end of the fixing ring 24, a second ring 26 that can rotate is sealingly and slidably connected to the inner wall of the second annular groove 25, the upper end of the hollow rod 18 is connected to the upper end of the second ring 26, and a plurality of air outlets 27 are provided on the inner wall of the hollow rod 18 located in the acid immersion tank 5.

[0044] A refrigeration frame 28 is fixedly connected to the side wall of the processing tank 1, a slide plate 29 is sealingly and slidably connected to the inner wall of the refrigeration frame 28, a refrigeration plate 47 is fixedly connected to the inner bottom of the refrigeration frame 28, a heat absorption end of the refrigeration plate 47 is located inside the refrigeration frame 28, and a heat release end of the refrigeration plate 47 is located outside the refrigeration frame 28, a one-way air intake pipe 48 is fixedly connected to the inner wall of the refrigeration frame 28, the inner bottom of the refrigeration frame 28 is connected to the top of the second annular groove 25 through a one-way air outlet pipe 31, and a ventilation pipe 30 is fixedly connected to the inner bottom of the refrigeration frame 28.

[0045] A first solenoid valve 32 is installed in the ventilation pipe 30, a second solenoid valve 33 is installed on the inner wall of the hollow rod 18 above the gear 21, and a temperature sensor 34 (such as Figure 3 As shown), the temperature sensor 34 is electrically connected to the first solenoid valve 32 through an external control mechanism, and the temperature sensor 34 is electrically connected to the corresponding first electric butterfly valve and second solenoid valve 33 through an external control mechanism.

[0046] It should be noted that the first solenoid valve 32 is a normally open solenoid valve, the second solenoid valve 33 is a normally closed solenoid valve, and the electric butterfly valve is powered on and opened when in use. The temperature sensor 34 can sense the temperature in the acid immersion box 5. When the temperature in the acid immersion box 5 is greater than 100°C, the first solenoid valve 32 is powered on and closed through an external control mechanism, the second solenoid valve 33 in the hollow rod 18 corresponding to the temperature sensor 34 is powered on and opened, and the first electric butterfly valve in the hard tube 13 corresponding to the temperature sensor 34 is powered off and closed, so that solid-state battery waste and sulfuric acid no longer enter the acid immersion box 5, which is convenient for the subsequent temperature reduction in the acid immersion box 5.

[0047] The upper end of the L-shaped plate is rotatably connected to a reciprocating screw 35, and the side wall of the reciprocating screw 35 is threadedly connected to a slider 36. The lower end of the slider 36 is fixedly connected to the upper end of the slide plate 29 through a plurality of vertical rods 37. The side walls of the first rod 16 and the reciprocating screw 35 are fixedly connected to synchronous wheels 38. A synchronous belt is connected between the two synchronous wheels 38. The side wall of the slider 36 is fixedly connected to a dredging rod 40 through a folding rod 39. The dredging rod 40 is located in the feed pipe 46.

[0048] The rotation of the first rod 16 will drive the reciprocating screw 35 to rotate through the synchronous belt and the two synchronous wheels 38. At this time, the slider 36 drives the slide plate 29 to slide up and down through multiple vertical rods 37, so that the space in the refrigeration frame 28 is intermittently increased and decreased. After the first solenoid valve 32 is powered on and closed, the refrigeration frame 28 can pump the cold air inside it into the second annular groove 25 through the one-way air outlet pipe 31. Then, the cold air will flow out from the multiple air outlets 27 through the hollow rod 18 opened by the second solenoid valve 33, and the cold air is pumped into the acid immersion box 5 to cool down the inside thereof, thereby avoiding the phenomenon in the prior art that if a violent reaction occurs and the temperature rises rapidly, it is easy to cause a low digestion rate of precious metal materials.

[0049] When the slider 36 moves up and down, the slider 36 drives the dredging rod 40 to move up and down in the feed pipe 46 through the folding rod 39, so as to dredge the electrolyte waste in the feed pipe 46 and avoid blockage in the feed pipe 46.

[0050] The inner wall of the feeding cylinder 6 below the inclined plate 8 is rotatably connected to a second rod 41 (such as Figure 8 As shown), the side wall of the second rod 41 is fixedly connected to a cam 42, and the side wall of the cam 42 cooperates with the lower part of the inclined plate 8 facing the feed pipe 46. The side wall of the first rod 16 is fixedly connected to a first bevel gear 43, and the side wall of the second rod 41 is fixedly connected to a second bevel gear 44, and the first bevel gear 43 and the second bevel gear 44 are meshed.

[0051] During the rotation of the first rod 16, the second rod 41 is driven to rotate by the first bevel gear 43 and the second bevel gear 44, and the cam 42 is driven to rotate. At this time, the cam 42 can intermittently collide with the corresponding inclined plate 8, thereby accelerating the outflow of electrolyte waste located above the inclined plate 8 and avoiding blockage in the opening 12 corresponding to the feed chamber 10.

[0052] An environmentally friendly method for treating waste materials in a battery manufacturing process comprises the following steps:

[0053] S1, placing sulfuric acid in liquid storage barrel 2, and placing the crushed electrolyte waste in storage barrel 3;

[0054] S2, the driving motor 17 rotates, and drives the three acid leaching boxes 5 to rotate through the first rod 16, the cylinder 14 and the three fixed plates 15, so that the three hard tubes 13 drive the first ring 11 to rotate, and at this time, sulfuric acid and electrolyte waste will intermittently fall into the acid leaching box 5 for reaction;

[0055] S3. After the reaction is completed, open the second electric butterfly valve located at the discharge pipe 23 to discharge the acid solution and waste materials for washing.

[0056] When the electrolyte waste is treated in an environmentally friendly manner, sulfuric acid is placed in the liquid storage barrel 2, and the crushed electrolyte waste is placed in the storage barrel 3. At this time, sulfuric acid will enter the liquid inlet chamber 9 through the liquid inlet pipe 45, and the electrolyte waste will enter the feed chamber 10 through the feed pipe 46. Then the motor 17 is driven to rotate, and the three acid leaching boxes 5 are driven to rotate through the first rod 16, the cylinder 14 and the three fixed plates 15, so that the three hard tubes 13 drive the first ring 11 to rotate, so that the three hard tubes 13 intermittently correspond to the openings 12 located in the liquid inlet chamber 9 and the feed chamber 10, so that sulfuric acid and electrolyte waste will intermittently fall into the acid leaching box 5 for reaction, avoiding the prior art that the solid-state battery waste and sulfuric acid are all added to the reaction tank at one time, resulting in uneven contact between the solid-state battery waste and sulfuric acid, and it takes a lot of time to make the two fully react. If a violent reaction occurs and the temperature rises rapidly, it cannot be rescued in time, which easily leads to a low digestion rate of precious metal materials;

[0057] During the rotation of the three acid leaching tanks 5, the three hollow rods 18 and the three gears 21 are driven to revolve. At this time, the three gears 21 rotate under the action of the gear ring 20, driving the three hollow rods 18 and the plurality of mixing rods 19 to rotate, so as to evenly mix the sulfuric acid and the electrolyte waste in the acid leaching tank 5, thereby accelerating the reaction efficiency of the electrolyte waste.

[0058] After the reaction is completed, it is only necessary to open the second electric butterfly valve located at the discharge pipe 23 to discharge the acid solution and waste materials for washing;

[0059] The rotation of the first rod 16 will drive the reciprocating screw 35 to rotate through the synchronous belt and the two synchronous wheels 38, and drive the slider 36 to slide up and down. At this time, the slider 36 will drive the dredging rod 40 to move up and down in the feed pipe 46 through the folding rod 39, so as to dredge the electrolyte waste in the feed pipe 46 to avoid blockage in the feed pipe 46. In addition, during the rotation of the first rod 16, the second rod 41 is driven to rotate through the first bevel gear 43 and the second bevel gear 44, and the cam 42 is driven to rotate. At this time, the cam 42 can intermittently collide with the corresponding inclined plate 8, thereby accelerating the outflow of electrolyte waste located above the inclined plate 8, and avoiding blockage in the opening 12 corresponding to the feed chamber 10.

[0060] Since the temperature sensor 34 can sense the temperature in the acid immersion box 5, when the temperature in the acid immersion box 5 is greater than 100°C, the first solenoid valve 32 is powered on and closed by the external control mechanism, the second solenoid valve 33 in the hollow rod 18 corresponding to the temperature sensor 34 is powered on and opened, and the first electric butterfly valve in the hard tube 13 corresponding to the temperature sensor 34 is powered off and closed, so that solid-state battery waste and sulfuric acid no longer enter the acid immersion box 5, which is convenient for the subsequent temperature reduction in the acid immersion box 5;

[0061] Since the slider 36 drives the slide plate 29 to slide up and down through multiple vertical rods 37, the space in the refrigeration frame 28 is intermittently increased and decreased. Under the action of the refrigeration plate 47, the refrigeration frame 28 can pump the cold air inside it into the second annular groove 25 through the one-way air outlet pipe 31, and then the cold air will flow out from the multiple air outlets 27 through the hollow rod 18 opened by the second solenoid valve 33, and the cold air is pumped into the acid immersion box 5 to cool the inside thereof, thereby avoiding the phenomenon in the prior art that if a violent reaction occurs and the temperature rises rapidly, it is easy to cause a low digestion rate of precious metal materials.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
