[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-Figure 5A grinding device for chemical mechanical pulp processing includes a main body 1, a grinding mechanism, an auxiliary mechanism and a transmission mechanism. The grinding mechanism includes a grinding motor 2, a grinding roller 3, a fixing frame 4 and a stirring piece 5. The grinding motor 2 is fixedly mounted on the bottom of the main body 1, the grinding roller 3 is fixedly connected to the output end of the grinding motor 2, the fixing frame 4 is fixedly mounted in the main body 1, and the stirring piece 5 is fixedly mounted on the grinding roller 3. The auxiliary mechanism includes a water pipe 6, a fixed plate 7, a water diversion plate 8, a water spray column 9 and a nozzle 10. One end of the water pipe 6 is fixedly mounted on the fixed plate 7, the fixed plate 7 is fixedly mounted on the main body 1, the water diversion plate 8 is fixedly mounted inside the main body 1, and a water spray column 9 is provided at the bottom of the water diversion plate 8. The water spray columns 9 are distributed in a circular array on the water diversion plate 8, and the nozzle 10 is fixedly mounted on the water spray column 9.

[0031] In this embodiment, the grinding mechanism includes a grinding motor 2, a grinding roller 3, a fixed frame 4 and a stirring piece 5. When in use, the grinding motor 2 is started, directly driving the grinding roller 3 to rotate in the grinding bin 26 in the fixed frame 4, thereby grinding the material dropped in the drop bin 18, and while the grinding roller 3 rotates, the stirring piece 5 fixedly mounted on the grinding roller 3 also starts to rotate in the drop bin 18, and the connecting frame 16 mounted on the stirring piece drives the scraper 17 to rotate in the drop bin 18, thereby scraping the material in the drop bin 18. Under the action of grinding, the material at this time falls into the discharge piece 20 under the influence of water flow and gravity under the cooperation of the auxiliary mechanism, and the drainage block 21 in the discharge piece 20 directly discharges the material. In order to prevent the material from sticking, the vibration motor 22 is started to shake off the boring on the inner wall of the discharge piece 20, thereby discharging it.

[0032] In this embodiment, the auxiliary mechanism includes a water pipe 6, a fixed plate 7, a water distribution plate 8, a water spray column 9 and a nozzle 10. When in use, the water flows in the water pipe 6 fixedly installed on the main body 1 through the fixed plate 7 and falls directly into the water distribution plate 8. After entering the water distribution plate 8, the water flows out in the water spray column 9 and flows out in the nozzle 10 through the water spray column 9. The water flow in the nozzle 10 directly rushes into the drop bin 18, so that the material contacts the water flow and falls into the grinding bin 26 under the influence of gravity.

[0033] In this embodiment, the transmission mechanism includes a transmission frame 11, a transmission belt 12, a feed pipe 13, a feed motor 14 and a feed shaft 15. When in use, the transmission frame 11 installed on the main body 1 is fixed, and the transmission belt 12 is running to put the material on the transmission belt 12. The transmission belt 12 is running to discharge the material into the main body 1 through the feed port 19 on the main body 1. The auxiliary mechanism and the grinding mechanism are used to grind the material. The ground material falls directly into the feed pipe 13 due to gravity and the action of the vibration motor 22. At this time, the feed motor 14 is running, driving the feed shaft 15 to rotate, so that the spiral blade 25 also rotates in the feed pipe 13 to transmit the ground material, and the transmitted material is finally discharged from the discharge port 24. In order to prevent the vibration motor 22 from vibrating the feed pipe 13 and damaging the spiral blade 25, the shock-absorbing pad 23 also eliminates the transmitted vibration force.

[0034] Example 2:

[0035] In summary, when in use, the transmission frame 11 installed on the main body 1 is fixed, and the transmission belt 12 runs, and the material is placed on the transmission belt 12. The transmission belt 12 runs, and the material is discharged into the main body 1 through the feeding port 19 on the main body 1, and the auxiliary mechanism and the grinding mechanism are used to grind the material. After the material enters the main body 1, the water flows in the water pipe 6 fixedly installed on the main body 1 through the fixed plate 7 and directly falls into the water diversion plate 8. After entering the water diversion plate 8, the water flows out in the water spray column 9, and flows out in the nozzle 10 through the water spray column 9, and the water flow in the nozzle 10 directly rushes into the drop bin 18, so that the material contacts the water flow and falls into the grinding bin 26 under the influence of gravity. At this time, the grinding motor 2 is started, which directly brings The dynamic grinding roller 3 rotates in the grinding bin 26 in the fixed frame 4, thereby grinding the material dropped in the drop bin 18, and while the grinding roller 3 rotates, the stirring piece 5 fixedly installed on the grinding roller 3 also starts to rotate in the drop bin 18, and the connecting frame 16 installed on the stirring piece drives the scraper 17 to rotate in the drop bin 18, thereby scraping the material in the drop bin 18. Under the action of grinding, the material at this time falls into the discharge piece 20 under the influence of water flow and gravity with the cooperation of the auxiliary mechanism, and the drainage block 21 in the discharge piece 20 directly discharges the material. In order to prevent the material from sticking, the vibration motor 22 is started to shake off the material on the inner wall of the discharge piece 20, thereby discharging it.
