Description

Technical Field

[0001] The utility model relates to the technical field of pot loading equipment for lithium battery cathode materials in the new energy material industry, and particularly relates to a pot loading and compaction device. Background Art

[0002] Lithium ion batteries have been widely used due to their characteristics such as energy storage, fast charge and discharge, long cycle life, and environmental friendliness. In addition, the cathode material is one of the key factors determining the performance of lithium ion batteries. In the production process of lithium battery cathode materials, the pot loading link is particularly important, that is, the powder material to be sintered needs to be first loaded into a specific specification crucible, and then the powder in the crucible is shaken and cut into pieces, so that oxygen can fully contact the material during the sintering process. Finally, the crucible filled with powder is sent to the track of the roller hearth kiln and then sent into the kiln for high-temperature sintering.

[0003] The pot loading equipment in the prior art usually adopts the "free fall" form, and the material falls into the crucible by its own gravity. This pot loading method has a low loading density, resulting in a low loading capacity of the crucible; at the same time, it is easy to generate more dust, with more material loss, serious waste, and an increase in the material preparation cost. Moreover, the material after pot loading generally needs to be shaken and cut into pieces. After cutting, the loose material often collapses in the kiln, failing to achieve the purpose of making the material fully contact and react with oxygen after sintering, thus affecting the material performance index.

[0029] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0030] Referring to Figures 1 to 4 , the following embodiments are made for the pot loading and compaction equipment of the present invention:

[0031] A pot loading and compaction equipment, comprising: a support 100, a pot loading device 200 and a compaction device 300.

[0032] The support 100 has a bowl conveying mechanism 110 for conveying the saggers. The bowl conveying mechanism 110 has a bowl body conveying surface for supporting and conveying the saggers. The bowl conveying mechanism 110 is sequentially provided with a bowl loading station and a compacting station along the conveying direction.

[0033] The bowl loading device 200 is disposed above the bowl loading station, and the bowl loading device 200 is used to load the saggers in the bowl loading station.

[0034] In this embodiment, the sagger conveying mechanism 110 is arranged along the front-to-back direction, and the sagger is conveyed from the back to the front through the sagger conveying mechanism 110. The compacting station is arranged at the front side of the sagger loading station.

[0035] The compacting device 300 is disposed above the compacting station and includes a pressing plate 310 and a compacting driving member 320. The compacting driving member 320 has a compacting driving end that is in transmission connection with the pressing plate 310 and enables the pressing plate 310 to move up and down relative to the bowl delivery mechanism 110.

[0036] In actual use, the saggers are transported by the sagger delivery mechanism 110 to pass under the sagger loading device 200 and the compacting device 300 one by one, and the sagger loading device 200 loads the material on the sagger. When the sagger loaded with the material is transported to the bottom of the compacting device 300, the compacting driving member 320 drives the pressing plate 310 downward to compact the material in the sagger. After the material in the sagger is compacted by the compacting device 300, the loading density is high, which effectively increases the loading amount of each sagger, reduces the dust in the subsequent process, and avoids collapse.

[0037] In this embodiment, the support 100 includes an upper frame and a lower frame arranged in an upper and lower manner. The bowl delivery mechanism 110 is arranged on the lower frame. The bowl delivery mechanism 110 adopts a roller conveying mechanism to convey the sagger thereon through a plurality of arranged conveying rollers. The bowl loading device 200 and the compacting device 300 are arranged above the bowl delivery mechanism 110 and connected to the upper frame.

[0038] In order to allow the material to fully contact and react with oxygen after sintering, a punching needle 330 is provided on the lower side of the pressing plate 310. The punching needles 330 all extend downward from the lower end surface of the pressing plate 310. There are multiple punching needles 330. The multiple punching needles 330 are evenly arranged and distributed. In the process of the pressing plate 310 pressing down to compact the material in the sagger, the multiple punching needles 330 are inserted into the material, thereby processing multiple pits in the compacted material, achieving dense punching so that oxygen can fully participate in the reaction of the positive electrode material.

[0039] In this embodiment, the cross-section of the punching needle 330 is in a "+" shape. The cross-section of the punching needle 330 specifically refers to the cross-section obtained when the punching needle 330 is intersected by a plane perpendicular to the up-down direction. Through the cross-shaped punching needle 330, a plurality of correspondingly shaped holes and grooves are densely processed in the material. The material blocks between the plurality of cross-shaped holes and grooves can not only fully react with oxygen but also are not prone to stuffing collapse.

[0040] Furthermore, to facilitate the insertion or extraction movement of the punching needle 330, reduce the insertion resistance, and avoid local collapse caused by material being carried out during extraction, the punching needle 330 has a certain draft angle and is in a shape that is thicker at the top and thinner at the bottom.

[0041] The compaction driving member 320 can adopt a linear driving member such as a cylinder, an electric push rod, a hydraulic push rod, or a lead screw-nut driving assembly. In this embodiment, the compaction driving member 320 includes: a compaction electric cylinder 321 and a compaction cylinder 322. The compaction electric cylinder 321 and the compaction cylinder 322 are both arranged along the up-down direction. The compaction cylinder 322 is arranged at the lower end of the telescopic rod of the compaction electric cylinder 321. The pressing plate 310 is arranged at the lower end of the piston rod of the compaction cylinder 322.

[0042] During actual use, the compaction electric cylinder 321 drives the compaction cylinder 322 and the pressing plate 310 to move downward. After the pressing plate 310 presses against the material in the sagger, it can compress the gas in the compaction cylinder 322 to avoid excessive extrusion of the material. When the compaction electric cylinder 321 drives the pressing plate 310 to move up and down, the moving speed can vary according to the distance from the sagger. The pressing plate 310 moves quickly first and then slowly during the downward pressing process, and moves slowly first and then quickly during the rising process, so as to avoid causing dust or collapse of the compacted material.

[0043] Furthermore, to facilitate the escape and discharge of air in the sagger and the material, the pressing plate 310 is a microporous structure plate product. During the compaction process, air can reach the upper side of the pressing plate 310 from the lower side of the pressing plate 310 through the internal micropores of the pressing plate 310. A filter member 340 is also provided between the pressing plate 310 and the compaction driving member 320, and the filter member 340 has a porous structure. The porous structure means that there are a large number of pores or holes inside the material. The sizes, shapes, distributions, etc. of these pores or holes are different, but the common point is that the overall material presents a non-dense and porous state. This structure can increase the specific surface area of the material and improve the adsorption, filtration, air permeability and other properties of the material. The filter member 340 is made of a material with a porous and fluffy structure, and it contains a large number of tiny pores or holes inside. Air enters the filter member 340 from the pressing plate 310, and the filter member 340 can intercept the powder in these pores to avoid the situation of powder flying.

[0044] The potting device 200 includes: a silo 210 and a stirring mechanism 220. The silo 210 is used to store the materials to be potted. The lower end of the silo 210 has a feeding port. The stirring mechanism 220 includes: a stirring paddle 222 and a stirring driving member 221. The stirring paddle 222 is arranged in the silo 210, and the stirring driving member 221 is used to drive the stirring paddle 222 to rotate.

[0045] In this embodiment, the silo 210 is in the shape of a rotating body. Specifically, both the upper end and the lower end of the silo 210 are in the shape of a cylindrical barrel, and the middle part of the silo 210 is in the shape of a conical barrel with a wider upper part and a narrower lower part, so that the overall shape of the silo 210 is in the shape of a funnel. The feeding port is arranged at the lower end of the middle part of the silo 210. An openable and closable air vent 212 and a feeding port 213 are provided at the upper end of the silo 210.

[0046] A first weighing module 211 is provided between the silo 210 and the bracket 100. The first weighing module 211 can weigh the silo 210 and the materials therein, so that the amount of materials in the silo 210 can be kept within an appropriate range, and can also monitor the potting amount each time.

[0047] In a further embodiment, a second weighing module 111 is provided on the lower side of the potting station. The second weighing module 111 can weigh the saggers in the potting station, so as to identify and measure the potting amount, and avoid the situation of over-potting or under-potting.

[0048] Refer to the appendix Figure 3 , the stirring paddle 222 includes: a main paddle 223 and branch paddles 224. Both the main paddle 223 and the branch paddles 224 are in the shape of long strips and extend in the vertical direction. A plurality of the branch paddles 224 are distributed circumferentially around the main paddle 223. The upper ends of the branch paddles 224 are fixedly connected to the main paddle 223. The upper end of the main paddle 223 is rotatably penetrated through the silo 210 and is drivingly connected to the stirring driving member 221.

[0049] Considering the convenience of controlling the rotation speed of the stirring paddle 222, the stirring driving member 221 in this embodiment adopts a servo motor. In some other embodiments, the stirring driving member 221 can be a stepping motor or a pneumatic motor and other rotary driving elements.

[0050] The lower end of the main paddle 223 has a spiral feeding part 2231 that extends spirally. The lower end of the spiral feeding part 2231 is arranged in the blanking port. Using the spiral feeding part 2231 as a spiral blade, the materials in the bin 210 are conveyed and stirred and mixed. When the stirring driving member 221 drives the stirring paddle 222 to rotate, the spiral feeding part 2231 can push the materials downward from the blanking port and output them.

[0051] In a further embodiment, the stirring paddle 222 further includes a cutting paddle 2232.

[0052] One end of the cutting paddle 2232 extending in the radial direction is connected to the main paddle 223, and the other end of the cutting paddle 2232 extending in the radial direction has a cutting part in the shape of a horizontal thin plate. The number of the cutting paddles 2232 is multiple, and the multiple cutting paddles 2232 are arranged along the axial direction of the main paddle 223. When the stirring paddle 222 rotates, the cutting paddle 2232 rotates around the main paddle 223, and provides a horizontal shearing force to the materials through the cutting part, thereby reducing the stratification phenomenon of the materials in the vertical direction.

[0053] In some other embodiments, the cutting part can also be inclined with respect to the horizontal direction. During the rotation of the cutting paddle 2232, it can not only shear and stir the materials but also axially push the materials, so that the materials are conveyed axially.

[0054] In a further embodiment, the stirring paddle 222 further includes a scraping paddle 2241.

[0055] One end of the scraping paddle 2241 extending in the radial direction is connected to the supporting paddle 224, and the other end of the scraping paddle 2241 extending in the radial direction has a scraping part. The scraping part extends along the inner wall of the bin 210 and abuts against the inner wall of the bin 210. When the stirring paddle 222 rotates, the scraping part can scrape off the materials on the inner wall of the bin 210, avoiding the adhesion of the materials on the inner wall of the bin 210.

[0056] Referring to the attached Figure 3 , in this embodiment, the scraping part of one of the scraping paddles 2241 extends in the up and down direction and abuts against the upper inner wall of the bin 210, and the scraping part of the other scraping paddle 2241 extends in an inclined direction and abuts against the middle inner wall of the bin 210.

[0057] To avoid abnormal noise caused by the mutual friction between the scraping part and the inner wall of the bin 210, a certain gap can be left between the scraping part and the inner wall of the bin 210. In some other embodiments, the scraping part can also be provided with a scraping edge made of a soft material, which can enhance the scraping effect while avoiding abnormal noise.

[0058] The pot loading and compaction device further includes a vacuum device 400. The vacuum device 400 includes a vacuum generating unit 410 and a vacuum tube 420. One end of the vacuum tube 420 is connected to the vacuum generating unit 410, and the other end is connected to the material discharging port and is provided with a filter screen. The vacuum generating unit 410 can generate negative pressure, so that the end of the vacuum tube 420 can suck the material discharging port, and the gas in the material at the material discharging port can be separated from the material. The filter screen can confine the material in the material discharging port to avoid waste. Further, the vacuum tube 420 is also connected to a filter element 340 in the compaction device 300. The negative pressure is transmitted through the vacuum tube 420, so that the gas discharged from the filter element 340 can also be discharged along the vacuum tube 420. The vacuum generating unit 410 can be a vacuum pump, a vacuum generator or a blower, etc.

[0059] A dust collecting device 500 is provided below the pot feeding mechanism 110. The dust collecting device 500 includes an ash collecting tray 510 and an ash collecting guide plate 520. The ash collecting guide plate 520 is arranged on the upper side of the ash collecting tray 510. The ash collecting guide plate 520 is inclined, and its lower end is connected to the edge of the ash collecting tray 510, so that the ash collecting guide plate 520 forms an ash collecting space that is wider at the top and narrower at the bottom on the upper side of the ash collecting tray 510. The floating dust can fall on the ash collecting guide plate 520 and fall into the ash collecting tray 510 along the ash collecting guide plate 520 for accumulation, which is convenient for cleaning.

[0060] Referring to Figures 1 to 4 , when actually using the pot loading and compaction device of the present invention for the production of pot loading of lithium battery cathode materials:

[0061] First, the material needs to be poured into the material bin 210, and the first weighing module is used to control and monitor the amount of material in the material bin 210. The empty pots to be loaded are placed one by one at the rear end of the pot feeding mechanism 110, and the pot feeding mechanism 110 can convey the pots from the rear to the front.

[0062] When the empty pot is conveyed to the pot loading station, the stirring driving member 221 drives the stirring paddle 222 to rotate. A plurality of the branch paddles 224 rotate around the main paddle 223 to realize the stirring of the material. The cutting paddle 2232 and the scraping paddle 2241 rotate synchronously. The cutting paddle 2232 is used to shear and stir the material, and the scraping paddle 2241 is used to prevent the material from adhering to the inner wall of the material bin 210. The spiral pushing part 2231 at the lower end of the main paddle 223 can push the material down from the material discharging port and drop it into the pot, realizing pot loading.

[0063] During the potting process, the vacuum generating unit 410 operates to generate negative pressure, and the materials at the material discharge port are vacuum suctioned through the vacuum tube 420 to reduce the air content of the materials, making the materials more compact, so as to increase the potting quantity and reduce the generation of dust. At the same time, the second weighing module 111 weighs the saggers at the potting station to achieve quantitative potting.

[0064] After the potting of the sagger is completed, it continues to be conveyed to the compaction station. The compaction driving member 320 drives the pressing plate 310 to move downward, and the pressing plate 310 presses the materials in the sagger downward. At the same time, the punching needles 330 on the lower side of the pressing plate 310 are inserted into the materials, so that corresponding shaped holes are processed in the materials during the compaction process. The air in the materials is further discharged during the compaction process, and after being filtered by the filter element 340, it is sucked away and discharged through the vacuum tube 420.

[0065] Each sagger passes through the potting station and the compaction station in sequence, and the potting and compaction and punching processes are carried out through the potting device 200 and the compaction device 300 in sequence.

[0066] The dust generated during the potting and compaction of the materials is collected to the dust collection tray 510 through the dust collection diversion plate 520 after settlement. When the accumulated dust reaches a certain amount, the materials in the dust collection tray 510 are recycled, which can improve the resource utilization rate.

[0067] Taking the potting production of 330-type saggers as an example: For the three different potting methods of "non-vacuum potting", "vacuum potting", or "vacuum + compaction potting", the corresponding potting filling rates are shown in the following table under different potting quantities.

[0068]

[0069] Taking the potting method of "non-vacuum potting" as a comparative example, it can be seen from Comparative Example 2 in the above table that when the potting quantity reaches 6924 g, the filling rate of the sagger materials reaches 100%.

[0070] The filling rate is the ratio of the volume of the potted materials to the volume of the sagger. Since in the conventional sintering treatment of ternary cathode materials, the sintering effect is better when the filling rate is lower than 80%. Therefore, when using the ordinary "non-vacuum potting" method for production, the potting quantity generally needs to be controlled at about 5000 g.

[0071] When using the "vacuum potting" method for production, the density of the potted materials increases. When the potting quantity is 5000 g, the filling rate is 61.38%, which is significantly lower than the production method of "non-vacuum potting".

[0072] When producing by the method of "vacuum pumping + compaction and potting", the density of the potted material is further increased compared with the method of "vacuum pumping and potting", and the filling rate of the 5000g potting amount is only 42.62%.

[0073] Therefore, when producing by the method of "vacuum pumping + compaction and potting", the potting amount of a single sagger can be controlled at 8500g, and the filling rate at this time is 72.46%. When producing by the method of "vacuum pumping and potting" or "non-vacuum pumping and potting", the theoretical filling rates of the 8500g potting amount are 104.34% and 122.75% respectively. The volume of the potted material is larger than the volume of the sagger, which will cause problems such as material overflow and waste, and at the same time affect the sintering quality.

[0074] It can be seen that using the potting compaction equipment of the present utility model to perform vacuum potting and compaction treatment on the potted material can greatly increase the potting amount and improve production efficiency.
