Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of waste solar silicon cell panel recycling, and relates to a waste solar silicon cell panel recycling device, in particular to a device for recycling waste solar silicon cell panels to manufacture high-efficiency silicon-carbon negative electrodes. BACKGROUND

[0002] A silicon solar cell panel is composed of an outer frame, a back plate, an encapsulation, tempered glass, a junction box and solar cells, and contains a large amount of valuable components, such as a large amount of silicon, aluminum and a small amount of silver, which have extremely high recycling value. Therefore, the recycling of waste solar silicon cell panels is imminent. Manufacturing silicon-carbon negative electrodes is a common processing technology for recycling waste solar silicon cell panels, and how to manufacture high-efficiency silicon-carbon negative electrodes in the recycling process of waste solar silicon cell panels increases the difficulty of recycling. Therefore, recycling waste solar silicon cell panels to manufacture high-efficiency silicon-carbon negative electrodes is a problem that needs to be solved urgently today.

[0003] At the same time, the materials in the waste silicon solar cell panel are relatively clean, and clean recycling and efficient utilization can be achieved through appropriate disposal in the recycling process. At present, the negative electrode material of lithium ion power battery is gradually changed to silicon-carbon negative electrode. This is because the silicon-based negative electrode has a high theoretical capacity, and the graphite negative electrode has reached the theoretical limit. The lithium storage mechanism of silicon negative electrode material is different from that of graphite negative electrode material, and the theoretical specific capacity is as high as 4200 mAh / g, which is about 10 times that of graphite negative electrode. At the same time, the cost of each kilowatt-hour of battery can be reduced by at least 3%. At the same time, the silicon-based negative electrode is safer. The silicon-based negative electrode material has a lower lithium extraction potential (~0.4V vs. Li / Li + ), which is slightly higher than that of graphite (~0.05V vs. Li / Li + ), and can avoid surface lithium precipitation during charging, and is not easy to produce lithium dendrites and cause battery short circuit.

DETAILED DESCRIPTION

[0035] The specific content of the present application is further explained and described in detail below in combination with the embodiments.

[0037] The cylindrical protective cover 3 is arranged in the cylinder body 1 and closely attached to its inner wall, and the inner wall of the protective cover 3 is closely attached to the lining plate 4; the protective cover 3 is made of one of high-strength steel materials such as 35CrMnSiA round steel and 35CrMnSiA composite steel, which plays a protective role.

[0041] The rotating shaft 8 is connected with the rotating grinding tool 9 through a shaft coupling, and a high-torque motor drives the rotating shaft 8 to rotate the rotating grinding tool 9, with a rotating speed of 200-2000 rpm and a rotating crushing temperature of 20-90℃. The rotating grinding tool 9 adopts a milling cutter process, and when working, it rotates to drive the grinding steel balls 10 in the grinding compartment 6 to a certain height to make the grinding steel balls 10 have a certain load to grind the materials, the grinding steel balls 10 are thrown to the outside of the grinding compartment 6 by centrifugal force, at the same time, the powder adhered to the sieve plates 5 of the grinding compartment 6 is shaken off, and then moves back to the center through the inverted conical structure of the sieve plates 5 to carry out the process of throwing and grinding again, wherein the ball-to-material ratio is 5:1 to 50:1, and the diameter of the grinding steel balls 10 in the grinding compartment 6 is 50%-100% larger than the hole diameter of the sieve plate 5 of the next level, which is acceptable, to prevent the grinding steel balls 10 from falling into the next level of grinding compartment 6 due to too small diameter, or reducing the crushing effect due to too large diameter.

[0042] The top of the cylinder body 1 is provided with a motor 11 for driving the rotating shaft 8;

[0043] The top of the cylinder body 1 is provided with a first feeding port 12 and a second feeding port 13, and the bottom is provided with a gas distribution pipe 14 and a discharge port, the discharge port is connected with a discharge pipeline 16 of a blowing device 15, and the tail end of the discharge pipeline 16 is provided with a material collecting tank 17; the first feeding port 12 and the second feeding port 13 respectively enter the uppermost grinding compartment 6, the gas distribution pipe 14 enters the lowermost grinding compartment 6, and the discharge port is connected with the lowermost grinding compartment 6;

[0044] When the distance meter 18 measures that the material in the last stage of grinding compartment 6 reaches 20% to 80% of the volume, the blowing device 15 is started, and the material is output to the material collecting box 17 through the discharge pipe 16, or the heating device is started to prepare the silicon-carbon negative electrode material.

[0045] The distance meter 18 and the thermometer 19 are arranged in each grinding compartment 6. The distance meter 18, the thermometer 19, the motor 11, the isolation plate 7, the first feeding port 12 and the second feeding port 13 are electrically connected to the main control board, and the main control board is electrically connected to the operation display screen 20 arranged on the outer wall of the cylinder. The distance meter 18 can be any one of an ultrasonic distance meter, an optical flow distance meter, an infrared distance meter and a laser distance meter.

[0046] The main control board can use any control core board with embedded development or can be used as a microcomputer, including STM32 series, 51 single-chip microcomputer series, Arduino series, Raspberry Pi, Jestson Nano, Jestson TX2, etc. The main function of the main control board is to receive the data of the thermometer 19, the distance meter 18 and the flow meter 25 through the software according to the program burned, and to control the driving mechanism to complete the corresponding operation according to the process requirements to meet the process requirements;

[0047] The operation display screen 20 can be set as a display screen for control operation, including the pre-set ball-material ratio, the current temperature of each grinding compartment 6, whether the isolation of each grinding compartment 6 is started, the material volume ratio of each grinding compartment 6 calculated by the distance meter 18, the discharge port flow, the heat treatment time of the last stage of grinding compartment 6, etc.

[0048] The inner wall of the grinding compartment 6 close to the bottom of the cylinder 1 is provided with a heat insulation plate 21, and the bottom is provided with a partition plate 22, and the partition plate 22 and the bottom surface of the cylinder 1 are provided with a heating cylinder 23;

[0049] The lower part of the isolation plate 7 close to the bottom of the cylinder 1 is provided with a folding heat insulation plate 24. The heat insulation plate 21 and the folding heat insulation plate 24 use common heat insulation materials such as glass fiber, asbestos, rock wool, silicate and vacuum plate; the folding heat insulation plate 24 is connected with the side wall of the cylinder 1 or the rotating shaft 8, and is driven to fold or shrink by the electric telescopic rod. The heat insulation plate 21 and the folding heat insulation plate 24 are used for heat preservation when the last stage of grinding compartment 6 is heated.

[0050] When the material in the last stage grinding compartment 6 reaches 20% to 80% of the volume, the heating cylinder 23 is heated, and the heat is uniformly transmitted to the last stage grinding compartment 6 through the partition plate 22, until the temperature reaches 500℃~2000℃, and then the temperature is maintained for 5min~20min; then the hot processed material powder is made to fall into the collection box 17 for collection by using the blowing device 15, and then the partition plate 22 and the folded heat insulation plate 24 of the last stage grinding compartment 6 are removed, so that the upper material powder falls down and the temperature is lowered. The calcination process is carried out in a protective atmosphere environment, and the gas distribution pipe is used to introduce a protective gas environment for the crushing process and the calcination process, so as to create a protective atmosphere. When the material is not subjected to heat treatment, the gas distribution pipe does not need to work.

[0051] The sieve plate 5 is arranged as a conical surface with the top point downward.

[0052] The isolation plate 7 is arranged in close contact with the sieve plate 5, and the isolation area of the isolation plate 7 is matched with the sieve plate 5; the isolation plate 7 can be arranged in a folding type and connected with the inner wall of the cylinder 1 or the rotating shaft 8, and is driven to fold or unfold by the electric telescopic rod in the radial direction. When unfolded, it is a conical surface, which blocks the falling of the upper material from the sieve hole;

[0053] Further, the isolation plate 7 can be arranged in an overlapping type sieve, when the isolation plate 7 completely overlaps the sieve plate 5, the sieve holes overlap, and the material falls through the sieve holes; when it is necessary to block the falling of the material, the electric telescopic rod drives the rotation of the isolation plate 7 to displace in the circumferential direction, until the sieve holes of the lower isolation plate 7 are completely misaligned with the sieve holes of the upper sieve plate 5, the sieve holes are closed, and the falling of the upper material from the sieve holes is blocked. When the electric telescopic rod is retracted, the sieve holes of the isolation plate 7 overlap the sieve holes of the sieve plate 5 again, and the material falls through the sieve plate 5.

[0054] When the distance between the materials is less than the set value sensed by the distance meter 18 installed in the grinding compartment 6, the operation display screen 20 controls the isolation plate 7 at the top of the grinding compartment 6 to enter the isolation state, so as to prevent the upper grinding compartment 6 from continuing to fall the material powder.

[0055] The first feeding port 12 is provided with a high-speed machining knife. The first feeding port 12 is connected to the front separation process to remove the waste solar silicon battery panel obtained by removing the tempered glass, frame, copper connecting line and other parts after screening, the high-speed machining knife rotates at a high speed, the rotation speed is 100r / min~1000r / min, and the material is subjected to preliminary crushing treatment;

[0056] The material added through the second feeding port 13 is one or any combination of crushing medium such as ethanol, methanol, isopropyl alcohol, n-hexane and N-methyl pyrrolidone, or one or any combination of conductive material such as KOH and dopamine hydrochloride; or one or any combination of carbon source material such as straw, waste paper and old newspapers; and subsequent materials such as carbon source and crushing medium; if necessary, a high-speed machining knife is installed at the second feeding port 13.

[0057] The first feeding port 12, the second feeding port 13 and the discharging port are all provided with a lining plate 4, so as to prevent material accumulation and ensure smooth feeding and discharging.

[0058] For preparing nanoscale silicon-carbon negative electrode products, the grinding compartment 6 is not less than fifteen layers.

[0059] The discharge pipeline 16 is provided with a flow meter 25; the flow meter 25 is electrically connected to the operation display screen 20. The flow meter 25 can be one of a volumetric flow meter, a turbine flow meter, an electromagnetic flow meter, an ultrasonic flow meter and a metal rotor flow meter.

[0060] The grinding steel balls 10 are gradually reduced from top to bottom; the reduction ratio of each stage should be 0.3-0.8 times.

[0061] The diameter of the grinding steel balls 10 in the grinding compartment 6 is 1 / 6-1 / 2 of the mesh diameter of the corresponding top sieve plate 5.

[0062] The intelligent device for recycling waste solar silicon battery panels to manufacture high-efficiency silicon-carbon negative electrodes of the application has the following process when in use:

[0063] Example 1:

[0064] The technician puts the whole set of waste polycrystalline silicon solar panels into the process line, and through the previous process line, the aluminum frame, copper wire, packaging material and tempered glass are removed, and only the silicon material is left. The disassembled waste polycrystalline silicon solar panels are added to the first feeding port 12, and after preliminary crushing by a high-speed processing knife, the feeding port is provided with a lining plate 4 to prevent material accumulation and ensure smooth material feeding. After crushing, it is sent into the partition compartment, the motor drives the rotating shaft 8 to rotate, thereby driving the rotating mill 9 to rotate and crush the waste polycrystalline silicon solar panels. At the same time, the rotating mill 9 drives the grinding steel balls 10 in each partition compartment to a certain height and then falls, thereby obtaining high kinetic energy to further crush the material. The screen plate 5 of each layer of grinding partition compartment 6 has a hole with a certain diameter, which ensures that when the material powder is smaller than a certain diameter, it can fall to the next layer of grinding partition compartment 6 for next-stage crushing and screening. At the same time, the steel balls in the grinding partition compartment 6 are larger in diameter to ensure that they cannot pass through the hole and be screened into the next layer of partition compartment. When the distance meter 18 senses that the distance between the material powder and the distance meter is small, the hole in the screen plate 5 in the current partition compartment and the upper grinding partition compartment 6 is blocked by the isolation plate 7 to prevent the material powder in the upper grinding partition compartment 6 from continuing to enter the current grinding partition compartment 6. Finally, the material powder meeting the diameter requirement flows out of the discharge pipe 16 to the material collecting box 17. When the flow meter 25 installed at the discharge port detects that the speed of the material powder flowing through is too slow, the rotating speed of the rotating shaft 8 is increased; when the flow meter 25 installed at the discharge port detects that the speed of the material powder flowing through is too slow, the rotating speed of the rotating shaft 8 is reduced, and the main control board drives the blowing device 15 to accelerate the blowing of the finished material powder. The lining plate 4 has small holes punched on it to ensure that the powder does not accumulate and the discharge is smooth, thereby obtaining micron or nanometer silicon powder after crushing.

[0065] Example 2:

[0066] The technician puts the whole set of waste polycrystalline silicon solar panels into the process line, and after the previous process line, the aluminum frame, copper wire, packaging material and tempered glass are removed, and only the silicon material is left. The waste polycrystalline silicon solar panels after disassembly are added to the first feeding port 12, and one or any combination of the crushing medium such as ethanol, methanol, isopropyl alcohol, n-hexane, N-methyl pyrrolidone, one or any combination of the conductive material such as KOH, dopamine hydrochloride, and one or any combination of the carbon source material such as straw, waste paper, and old newspapers are added to the second feeding port 13. After the materials added to the first feeding port 12 and the second feeding port 13 are preliminarily crushed by the high-speed processing knife, they are sent to the grinding compartment 6. The motor 11 drives the rotating shaft 8 to rotate, thereby driving the rotating mill 9 to rotate and crush the waste polycrystalline silicon solar panels and the carbon source and mix them thoroughly. At the same time, the rotating mill 9 drives the grinding steel balls 10 in each compartment to a certain height and then drops, thereby obtaining high kinetic energy to further crush the materials. Each grinding compartment 6 has a screen plate 5 with holes of a certain diameter, which ensures that when the material powder is smaller than a certain diameter, it can fall to the next grinding compartment 6 for further crushing and screening. When the distance meter 18 senses that the material powder is close to the distance meter, the isolation plate 7 is started to prevent the material powder in the upper grinding compartment 6 from continuing to enter the current grinding compartment 6. When the material powder passes through the screening of the last screen plate 5 and falls into the last grinding compartment 6, when the thermometer 19 detects that the temperature rises to the set temperature, the last isolation plate 7 is started to prevent the material powder in the upper grinding compartment 6 from entering the last grinding compartment 6. The heating cylinder 23 heats the material powder for calcination, and the gas distribution pipe 14 fills the protective gas to ensure that the material is in a protective environment during heat treatment. At the same time, the rotating mill 9 stirs to ensure uniform heating of the material powder. Finally, the material powder that meets the diameter requirement and has been heated and calcined by the heating cylinder 23 flows from the discharge pipe 16 to the material collection tank 17. When the flow meter 25 installed at the discharge port detects that the flow rate of the material powder is too slow, the main control board drives the blowing device 15 to blow the finished material powder for collection of mature and efficient silicon-carbon negative electrode material.

After the materials added to the first feeding port 12 and the second feeding port 13 are preliminarily crushed by the high-speed processing knife, they are sent to the grinding compartment 6. The motor 11 drives the rotating shaft 8 to rotate, thereby driving the rotating mill 9 to rotate and crush the waste polycrystalline silicon solar panels and the carbon source and mix them thoroughly. At the same time, the rotating mill 9 drives the grinding steel balls 10 in each compartment to a certain height and then drops, thereby obtaining high kinetic energy to further crush the materials. Each grinding compartment 6 has a screen plate 5 with holes of a certain diameter, which ensures that when the material powder is smaller than a certain diameter, it can fall to the next grinding compartment 6 for further crushing and screening. When the distance meter 18 senses that the material powder is close to the distance meter, the isolation plate 7 is started to prevent the material powder in the upper grinding compartment 6 from continuing to enter the current grinding compartment 6.
