[0033] The steel balls and the grinding powder are fed into the grinding tank 2 through the feeding pipe, and then the motor 19 is started to make the connecting rod 18 start to rotate. The rotation of the connecting rod 18 drives the grinding tank 2 to rotate, so as to effectively grind the steel balls inside. During the grinding process, the isolation net 5 installed on the bottom support frame 4 effectively separates the steel balls and the grinding powder. The grinding powder deposited during the grinding process is transported to the inside of the powder box 9 through the auger 8, and the debris generated during the grinding process is processed and adsorbed by the magnet 12. At the same time, the motor 15 is started to make the rotating shaft 11 start to rotate, thereby driving the magnet 12 to rotate. The rotation of the magnet 12 enables the shell 13 to scrape off the adsorbed debris, and the scraped debris is transported to the inside of the connecting pipe 16 through the fixed pipe 14. At the same time, the processed grinding powder is discharged through the concave hole 10. When the discharged grinding powder passes through the filter screen 6, it will be further filtered to ensure that the debris not absorbed is filtered out.

[0034] Reference Figure 4 and Figure 5 The grinding tank 2 is fixedly connected with a connecting pipe 16 inside, and the side wall of the fixed pipe 14 is fixedly connected to the side wall of the connecting pipe 16. The side wall of the grinding tank 2 is fixedly connected with a slag discharge pipe 17, and the slag discharge pipe 17 is used to discharge debris. The side wall of the grinding tank 2 is provided with a debris box 20, and the debris box 20 is used to collect debris. The side wall of the grinding tank 2 is rotatably connected with a rotating rod 21, and the side wall of the rotating rod 21 is fixedly connected with a connecting plate 22. A fixing pin 23 is slidably connected inside the connecting plate 22, and the fixing pin 23 is used to fix the debris box 20. The side wall of the fixing pin 23 is fixedly connected to a limiting plate 24, and the side wall of the limiting plate 24 is fixedly connected with a pull ring 25, and the pull ring 25 is used to pull the fixing pin 23. The side wall of the fixing pin 23 is slidably connected to the inside of the grinding tank 2, and the side wall of the fixing pin 23 is sleeved with a spring 26, and the spring 26 is used for rebounding and resetting. One end of the spring 26 is fixedly connected to the side wall of the connecting plate 22, and the other end of the spring 26 is fixedly connected to the side wall of the limiting plate 24;
[0035] The debris is conveyed through the connecting pipe 16 to the inside of the slag discharge pipe 17. After being guided by the slag discharge pipe 17, it enters the inside of the debris box 20. When the debris box 20 is gradually filled and needs to be cleaned, the operator can pull the fixing pin 23 through the pull ring 25 to make it slide, so as to extract the fixing pin 23 from the inside of the grinding tank 2. Subsequently, at the deflecting connecting plate 22, the debris box 20 loses its original restraint and can be taken down. Next, the operator can thoroughly clean the debris collected inside the debris box 20. After the cleaning work is completed, the debris box 20 is hung back on the side wall of the grinding tank 2 again. Subsequently, the fixing pin 23 is pulled again through the pull ring 25, and then the deflecting connecting plate 22 is deflected to ensure that the fixing pin 23 is completely aligned with the hole inside the grinding tank 2. Finally, the pull ring 25 is released. At this time, the spring 26 loses pressure and resets, so as to insert the fixing pin 23 back into the inside of the grinding tank 2 again to ensure that the debris box 20 is firmly fixed. In this way, the entire cleaning process is successfully completed.
[0036] Working principle: The steel balls and grinding powder are fed into the inside of the grinding tank 2 from the feeding pipe. Then, the motor two 19 is started to make the connecting rod 18 rotate, so that the grinding tank 2 rotates to grind the steel balls inside. The isolation net 5 installed on the bottom support frame 4 separates the steel balls and the grinding powder. At the same time, the auger 8 conveys the grinding powder at the bottom to the inside of the powder box 9. The debris ground by the magnet 12 is processed. At the same time, the motor one 15 is started to make the rotating shaft 11 rotate, driving the magnet 12 to rotate. The rotation of the magnet 12 causes the outer shell 13 to scrape off the debris absorbed by the magnet 12. The scraped debris is conveyed through the fixed pipe 14 to the inside of the connecting pipe 16. At the same time, the processed grinding powder is discharged through the concave holes 10, and the discharged grinding powder is filtered through the filter screen 6 to filter out the debris that has not been sucked.
[0037] The debris is conveyed by the connecting pipe 16 to the inside of the slag discharge pipe 17 and then discharged through the slag discharge pipe 17 into the inside of the debris box 20. When the debris box 20 is full and needs to be cleaned, the fixing pin 23 can be pulled through the pull ring 25 to slide, and it is extracted from the inside of the grinding tank 2. After that, the deflecting connecting plate 22 is deflected. At this time, the debris box 20 loses its restraint and can be taken down to clean the debris collected inside the debris box 20. After the cleaning is completed, the debris box 20 is hung back on the side wall of the grinding tank 2 again, and the fixing pin 23 is pulled again through the pull ring 25, and then the deflecting connecting plate 22 is deflected to align the fixing pin with the hole inside the grinding tank 2. Then the pull ring 25 is released. At this time, the spring 26 loses pressure and resets, so as to insert the fixing pin 23 back into the inside of the grinding tank 2 to fix the debris box 20.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
