Description

Technical Field

[0001] This utility model relates to the field of sagger cleaning technology, specifically a cleaning device for sintering saggers of battery positive electrode materials. Background Technology

[0002] Sintering crucibles are typically used during the sintering of lithium-ion battery cathode materials. These crucibles are special containers used for sintering materials at high temperatures. They need to possess characteristics such as high temperature resistance, corrosion resistance, and good thermal conductivity to ensure that the material is heated uniformly during the sintering process and achieves the desired structure and performance. During the actual sintering process, the material releases gases that may adhere to the surface of the crucible. If the crucible is not cleaned, the deposits on it may affect the purity and performance of the material in the next sintering. Therefore, the crucible needs to be cleaned in a timely manner. However, due to the large size of some crucibles, cleaning them requires a lot of time and labor, and the cleaning efficiency is not high.

[0003] To address the aforementioned technical problems of time-consuming, labor-intensive, and inefficient crucible cleaning, Chinese Patent CN222288250U discloses a cleaning device for sintering crucibles of lithium battery cathode materials. The device includes a cleaning device housing; a conveying assembly disposed on both sides of the housing; crucibles placed above the conveying assembly; and a cleaning assembly comprising a filter plate, a water tank, a first water pipe, a water pump, a second water pipe, and nozzles. The filter plate is detachably installed at the bottom of the housing, the water tank is installed below the filter plate, one end of the first water pipe is fixedly connected to the interior of the water tank, the pump's suction end is fixedly connected to the end of the first water pipe furthest from the water tank, one end of the second water pipe is fixedly connected to the pump's outlet end, and nozzles are installed at the ends of the second water pipe furthest from the pump. The crucibles are cleaned by spraying water through the nozzles and then dried by a hot air blower.

[0004] While the above-mentioned technical solution can complete the cleaning of the crucibles, some spray water remains inside after the spray nozzles rinse the crucibles. Since this remaining water increases the drying time, in actual cleaning, personnel may need to empty the water from the crucibles before proceeding with the subsequent drying process. This need to empty the water from the crucibles increases labor intensity and labor costs. Utility Model Content

[0020] Example 1

[0021] like Figure 1 As shown, a cleaning device for sintering saggers of battery cathode materials includes a cleaning component 1 for cleaning the sagger 2, a conveying and turning component for conveying and turning out the water in the sagger 2, and a drying component 11 for drying the sagger 2. The conveying and turning component is arranged on the cleaning platform 10, and the cleaning component 1 and the drying component 11 are arranged sequentially along the conveying direction of the conveying and turning component.

[0022] The conveying and turning assembly includes a primary conveying roller group 3, a secondary conveying roller group 6, and a tertiary conveying roller group 8 arranged sequentially from right to left, with their heights decreasing sequentially. The primary conveying roller group 3 includes a first frame 301, six conveying rollers evenly spaced on the first frame 301, and a first drive motor fixed on the first frame 301. The rightmost of the six conveying rollers is the primary driving conveying roller, and the other five are primary driven conveying rollers. A transmission gear is fixed on the shaft at both ends of each of the five primary driven conveying rollers, and the transmission gears of adjacent primary driven conveying rollers are connected by chain drive.

[0023] A drive gear is mounted on the shaft at one end of the primary drive conveyor roller. The drive gear is connected to the transmission gear on the adjacent primary driven conveyor roller via a chain drive. The other end of the primary drive conveyor roller is connected to the output shaft of the first drive motor via a reducer. The first drive motor drives the drive gear to rotate, thereby causing the other primary driven conveyor rollers to rotate synchronously. The water-filled sagger 2, cleaned by the cleaning assembly 1, is moved to the primary conveyor roller group 3, and the rotation of the primary conveyor roller group 3 transfers the water-filled sagger 2 to the secondary conveyor roller group 6.

[0024] The secondary conveyor roller group 6 is located to the left of the primary conveyor roller group 3. The sagger 2, which moves to the left end of the primary conveyor roller group 3, tilts downward under its own weight. A first vertical baffle 5 is fixed on the secondary conveyor roller group 6, and the lower end of the tilted sagger 2 can abut against the first vertical baffle 5. A first cylinder 4 is fixed on the first frame 301 between the primary conveyor roller group 3 and the secondary conveyor roller group 6 by a bracket. The piston rod of the first cylinder 4 is set towards the back of the sagger 2.

[0025] On one hand, the first vertical baffle 5 can block the lower end of the sagger 2; on the other hand, the piston rod of the first cylinder 4 extends and can push the upper part of the sagger 2 to flip so that its bottom surface faces upward. When the sagger 2 is tilted, some water can be poured out, and when the sagger 2 is completely flipped, all the water inside can be poured out.

[0026] The secondary conveyor roller group 6 includes a second frame 601, five conveyor rollers mounted on the second frame 601, and a second drive motor mounted on the second frame 601. The rightmost of the five conveyor rollers is the secondary active conveyor roller, and the other four are secondary driven conveyor rollers. A transmission gear is fixed on the rotating shaft at both ends of the four secondary driven conveyor rollers. The transmission gears of adjacent secondary driven conveyor rollers are connected by chain drive.

[0027] A drive gear is mounted on the shaft at one end of the secondary active conveyor roller. This drive gear is connected to the transmission gear on the adjacent secondary driven conveyor roller via a chain drive. The other end of the secondary active conveyor roller is connected to the output shaft of the second drive motor via a reducer. The second drive motor drives the remaining secondary driven conveyor rollers to rotate synchronously by rotating the drive gear. As the secondary driven conveyor rollers rotate, the bottom-facing crucible 2 is moved onto the tertiary conveyor roller group 8, and the bottom-facing crucible 2 is flipped to a face-up position for subsequent drying.

[0028] When the bottom-facing sagger 2 is moved to the left end of the secondary conveyor roller group 6, it tilts under its own weight. A second vertical baffle 9 is provided on the tertiary conveyor roller group 8, and the upper end of the second vertical baffle 9 can abut against the lower end of the sagger 2. A second cylinder 7 is provided on the second frame 601 between the secondary conveyor roller group 6 and the tertiary conveyor roller group 8. The piston rod of the second cylinder 7 extends and can push the sagger 2 to flip to a position where its front side faces upward.

[0029] The three-stage conveyor roller group 8 includes a third frame 801, six conveyor rollers mounted on the third frame 801, and a third drive motor mounted on the third frame 801. Among the six conveyor rollers, the one located at the rightmost end is the third-stage active conveyor roller, and the other five are third-stage driven conveyor rollers. A transmission gear is fixed on the rotating shaft at both ends of each of the five third-stage driven conveyor rollers, and the transmission gears of adjacent third-stage driven conveyor rollers are connected by chain drive.

[0030] A drive gear is mounted on the shaft at one end of the three-stage active conveyor roller. This drive gear is connected to the transmission gear on the adjacent three-stage driven conveyor roller via a chain drive. The other end of the three-stage active conveyor roller is connected to the output shaft of the third drive motor via a reducer. The third drive motor drives the other three-stage driven conveyor rollers to rotate synchronously by rotating the drive gear. As the three-stage driven conveyor rollers rotate, the face-up crucible 2 is moved to the drying assembly 11 for drying.

[0031] Furthermore, the cleaning assembly 1 includes a water storage tank fixedly mounted on the outer wall of the first frame 301 and a spray nozzle 101 for spraying water, positioned above the primary conveyor roller group 3. The spray nozzle 101 is connected to the water storage tank via a water supply pipe 102, and a water pump is connected to the water supply pipe 102. The spray nozzle 101 sprays water through multiple nozzles, some of which are vertically downward, while others are angled. The vertically downward nozzles and the angled nozzles are distributed alternately to better clean the deposits on the crucible 2.

[0032] Furthermore, the drying assembly 11 includes a drying hood 112 disposed above the three-stage conveyor roller group 8 and a hot air blower fixedly disposed on the third frame 801. The drying hood 112 is connected to the hot air blower through a hot air pipe 111 to dry the crucible 2.

[0033] The cleaning process of the sagger in this invention is as follows: First, the first drive motor starts, and the first-stage active conveying roller on the first-stage conveying roller group 3 rotates, driving the first-stage driven conveying roller to rotate via a chain. The rotating first-stage conveying roller group 3 moves the sagger 2 to a stop below the nozzle 101. The water pump is started, and the nozzle 101 sprays water to clean the sagger 2. After cleaning, the sagger 2 tilts as it is conveyed down from the first-stage conveying roller group 3 to the second-stage conveying roller group 6. Under the obstruction of the first vertical baffle 5 and the push of the first cylinder 4, the sagger 2 flips over so that its bottom surface faces upward, allowing the water to be poured out. The second drive motor starts, and the flipped sagger 2 is conveyed down to the third-level conveyor roller group 8 by the second-level conveyor roller group 6. When the sagger 2 with its bottom surface facing up is moved from the second-level conveyor roller group 6 to the third-level conveyor roller group 8, it tilts. Under the push of the second vertical baffle 9 and the second cylinder 7, the sagger 2 flips to its front surface facing up. The sagger 2 moves to the bottom of the drying hood 112 and stops as the third-level conveyor roller group 8 rotates. The hot air blower starts, and the sagger 2 is dried.

The first inclined conveyor roller group 12 is used to transfer the sacrificial vessel 2 from the first-stage conveyor roller group 3 to the second-stage conveyor roller group 6. A second inclined conveyor roller group 13 is provided between the second-stage conveyor roller group 6 and the third-stage conveyor roller group 8. The second inclined conveyor roller group 13 is used to transport the sacrificial vessel 2 from the second-stage conveyor roller group 6 to the third-stage conveyor roller group 8.

[0036] The first inclined conveyor roller group 12 and the second inclined conveyor roller group 13 have the same structure. The first inclined conveyor roller group 12 is fixed to the first frame 301 by a mounting bracket, and the first cylinder 4 is fixed to the mounting bracket by a bracket. The piston rod of the first cylinder 4 is located at the upper position of the first inclined conveyor roller group 12. The second inclined conveyor roller group 13 is fixed to the second frame 601 by a mounting bracket, and the second cylinder 7 is fixed to the corresponding mounting bracket by a bracket.

[0037] Both the first inclined conveyor roller group 12 and the second inclined conveyor roller group 13 include four rotating shafts, which are evenly mounted on corresponding mounting frames. Each rotating shaft is fitted with a rotatable roller.
