Detailed implementation manners
[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.
[0024] Such as Figures 1 to 5As shown in the figure, a leakage prevention device for the feed pipe of a wet ball mill according to an embodiment of the present utility model includes an end cover 1; a feed pipe body 11 is installed in the middle of the end cover 1; a fixing block 12 is fixedly connected to the side wall of the end cover 1; a chute 13 is opened in the middle of the fixing block 12; a collection box 14 is rotatably connected in the middle of the chute 13; the middle of the collection box 14 is inclined; the end of the collection box 14 is fixedly connected to the middle of the feed pipe body 11; a suction pump 16 is fixedly connected to the middle of the feed pipe body 11; a feed pipe 15 is fixedly connected to the middle of the suction pump 16; the end of the feed pipe 15 is fixedly connected to the side wall of the collection box 14; a discharge pipe 17 is fixedly connected to the middle of the suction pump 16; the discharge pipe 17 penetrates through the middle of the feed pipe body 11; during operation, it rotates when the ball mill is running, and at the same time the fixing block 12 rotates with the end cover 1. When the fixing block 12 rotates, one end of the collection box 14 remains stationary on the feed pipe body 11, and the other end of the collection box 14 slides in the middle of the chute 13. When the ball mill is working, the slurry inside leaks from the gap between the end cover 1 and the feed pipe body 11. The slurry enters the inside of the collection box 14. Since the middle of the collection box 14 is inclined, when the slurry enters the inside of the collection box 14, it accumulates at one end along the middle of the collection box 14. After the suction pump 16 is powered on and started, the slurry collected inside the collection box 14 enters the middle of the feed pipe 15 through the power provided by the suction pump 16, and then is discharged into the ball mill through the discharge pipe 17 due to the increased pressure. The collection box 14 can timely collect the slurry leaked from the gap between the end cover 1 and the feed pipe body 11 inside the ball mill, which can effectively reduce the shutdown and maintenance time of the ball mill caused by slurry leakage, and can timely discharge the leaked slurry back into the ball mill, which can recycle and utilize the leaked slurry, can effectively reduce the solidification of the slurry generated in the collection box 14 for a long time, effectively reduce the problem of waste caused by the leaked slurry, and can effectively reduce the problem of increased wear caused by the long-term contact between the slurry and the end cover 1 and the feed pipe body 11.
[0025] As Figure 1 , Figure 2 , Figure 5As shown, a push plate 2 is slidably connected to the middle of the feed pipe body 11; the push plate 2 is arranged inside the collection box 14; two connecting rods 21 are fixedly connected to the side wall of the push plate 2; the two connecting rods 21 are arranged oppositely; the middle of the connecting rod 21 penetrates through the side wall of the collection box 14; during operation, after the ball mill operates for a period of time, hold one end of the two connecting rods 21 and push them towards the feed pipe body 11. The push plate 2 is pushed to slide in the middle of the feed pipe body 11 through the two connecting rods 21. When the push plate 2 passes through the gap between the end cover 1 and the feed pipe body 11, the slurry in the gap is cleaned by the push plate 2 and pushed into the ball mill. Through the push plate 2, the slurry residue in the gap between the end cover 1 and the feed pipe body 11 can be cleaned in time, which can effectively reduce the time for shutdown treatment caused by the residue of the slurry between the end cover 1 and the feed pipe body 11, reduce the waiting time for the residue to be completely dried or solidified before cleaning, and can effectively reduce the aggravation of wear between the end cover 1 and the feed pipe body 11 caused by the long-term residue of the slurry in the gap, effectively reducing the replacement frequency and cost of components.
[0026] As Figure 1 , Figure 2 , Figure 4 shown, a heating wire 3 is fixedly connected to the middle of the feed pipe 15; the heating wire 3 is fixedly connected to the outside of the feed pipe 15; during operation, after the slurry is collected, the heating wire 3 is powered on and turned on, so that heat is generated on the surface of the heating wire 3. The heat on the surface of the heating wire 3 is transferred to the feed pipe 15. When the slurry is sucked by the feed pipe 15, the slurry is heated when passing through the middle of the feed pipe 15. Through the heating wire 3, the viscosity of the sucked slurry can be effectively reduced, the fluidity of the slurry can be effectively increased, the problem of solidification and caking of the slurry during the collection process can be effectively reduced, and the blockage of the slurry entering the inside of the feed pipe 15 can be effectively reduced, so that the leaked slurry can be effectively transported into the ball mill. Moreover, the heated slurry can be more easily evenly distributed inside the end cover 1 and the ball mill, and thus it is easier to mix with the slurry that has not leaked inside the ball mill.
[0027] As Figure 3As shown, a fixing plate 4 is fixedly connected to the side wall of the fixing block 12; the fixing plate 4 is inclined; a scraping plate 41 is fixedly connected to the middle of the fixing plate 4; the end of the scraping plate 41 is attached to the surface of the collection box 14; during operation, when the end cover 1 rotates with the operation of the ball mill, the fixing block 12 is driven to rotate at the same time, and the scraping plate 41 rotates while rotating with the fixing block 12. By fitting the scraping plate 41 to the inner wall of the collection box 14, the residue on the inner wall of the collection box 14 is scraped off by the scraping plate 41. Through the fixing block 12, the scraping plate 41 can continuously scrape the inner wall of the collection box 14, effectively cleaning the slurry residue adhering to the inner wall of the collection box 14, effectively reducing the problem of the decline in collection efficiency caused by excessive accumulation of slurry residues on the inner wall of the collection box 14, and timely cleaning the slurry residue on the collection box 14 can effectively reduce the wear and corrosion of the collection box 14, thereby effectively increasing the service life of the collection box 14 and reducing the frequency of replacement of the collection box 14.
[0028] As Figure 2 shown, a baffle 5 is fixedly connected to the end of the feed pipe body 11; the baffle 5 is arc-shaped; the baffle 5 is fixedly connected to one end close to the end cover 1; during operation, the slurry inside the ball mill will splash during the grinding process. The baffle 5 blocks the splashing slurry at one end of the feed pipe body 11, and the baffle 5 can directly block the slurry rotating or flowing at high speed inside the ball mill from splashing into the gap between the end cover 1 and the feed pipe body 11, effectively reducing the problem of slurry leakage, effectively improving the sealing performance between the end cover 1 and the feed pipe body 11, effectively reducing the waste and loss during the production process caused by slurry leakage, and effectively improving the resource utilization efficiency.
[0029] As Figure 2 and Figure 5 shown, a sponge block 6 is installed in the middle of the push plate 2; the sponge block 6 is fixedly connected to the middle of the push plate 2; during operation, when the push plate 2 moves, the sponge block 6 contacts the surface of the end cover 1. The sponge block 6 can effectively reduce the friction generated by direct contact with the surface of the end cover 1 during the process of the push plate 2 cleaning the slurry, effectively reducing the wear problem caused by the friction between the push plate 2 and the surface of the end cover 1, and can effectively adapt to the size of the gap between the end cover 1 and the feed pipe body 11, effectively improving the cleaning efficiency of the slurry.
[0030] During operation, it rotates while the ball mill is running. At the same time, the fixed block 12 rotates along with the end cover 1. During the rotation of the fixed block 12, one end of the collection box 14 remains stationary on the main body 11 of the feed pipe, and the other end of the collection box 14 slides in the middle of the chute 13. When the ball mill is working, the slurry inside leaks from the gap between the end cover 1 and the main body 11 of the feed pipe. The slurry enters the inside of the collection box 14. Since the middle of the collection box 14 is inclined, when the slurry enters the inside of the collection box 14, it accumulates at one end along the middle of the collection box 14. After the suction pump 16 is powered on and started, the slurry collected inside the collection box 14 enters the middle of the feed pipe 15 through the power provided by the suction pump 16, and then is discharged into the ball mill through the discharge pipe 17 due to the increased pressure. After the ball mill has run for a period of time, hold one end of the two connecting rods 21 and push it towards the main body 11 of the feed pipe. The push plate 2 slides in the middle of the main body 11 of the feed pipe by the push of the two connecting rods 21. When the push plate 2 passes through the gap between the end cover 1 and the main body 11 of the feed pipe, the slurry in the gap is cleaned by the push plate 2 and pushed into the ball mill. After the slurry is collected, the heating wire 3 is powered on and started to generate heat on the surface of the heating wire 3. The heat on the surface of the heating wire 3 is transferred to the feed pipe 15. When the slurry is sucked into the feed pipe 15, the slurry is heated when passing through the middle of the feed pipe 15. During the rotation of the end cover 1 along with the operation of the ball mill, the fixed block 12 is driven to rotate at the same time. The scraping plate 41 rotates simultaneously with the rotation of the fixed block 12. By fitting the scraping plate 41 to the inner wall of the collection box 14, the residue on the inner wall of the collection box 14 is scraped off by the scraping plate 41. The slurry inside the ball mill will splash during the grinding process. The splashing slurry is blocked by the baffle 5 at one end of the main body 11 of the feed pipe. When the push plate 2 moves, the sponge block 6 contacts the surface of the end cover 1.
