[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes a pulp beating and refining device for special paper production, which includes a fixed base 1 and a beating structure 2. The beating structure 2 is disposed on the fixed base 1 and includes a refining unit 3 and a feeding and discharging unit 4. The refining unit 3 is disposed on the fixed base 1 and the feeding and discharging unit 4 is disposed on the fixed base 1.

[0021] The fine grinding unit 3 includes a base 5, a motor 6, a rotating disk 7, a fine grinding ring 8, a threaded rod 9, a fine grinding ring 10, a fixed disk 11, and a feed pipe 12. The base 5 is fixedly mounted on the bottom of the fixed seat 1. The motor 6 is fixedly mounted on the base 5. The rotating disk 7 is fixedly mounted on the output shaft of the motor 6. The fine grinding ring 8 is fixedly mounted vertically on the rotating disk 7 and arranged in three groups from the inside to the outside at equal intervals. The threaded rod 9 is fixedly mounted in the middle position of the rotating disk 7. The fine grinding ring 10 is inserted into the gap formed by the three groups of fine grinding rings 8 and is arranged in four groups. The fine grinding rings 18 and 210 are arranged to rotate relative to each other and the gap between the fine grinding rings 18 and 210 is small. The surfaces of the fine grinding rings 18 and 210 are set with a rough diamond surface. The fine grinding rings 18 and 210 form a folded and bent grinding channel. The fixed disk 11 is fixedly mounted above the threaded rod 9. The feed pipe 12 passes through the fixed disk 11 and passes through the threaded rod 9.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the feeding and discharging unit 4 includes a collection tank 14, a protective cover 16, and a discharge pipe 17. The collection tank 14 is fixedly mounted on the fixed base 1. The protective cover 16 is inserted into the top of the collection tank 14, and the support frame 15 is recessed in the middle of the collection tank 14. The discharge pipe 17 passes through the fixed base 1 and is fixedly connected to the bottom of the collection tank 14.

[0023] like Figure 3 and Figure 4 As shown, the feeding hopper 13 is fixedly installed above the feeding pipe 12 and connected to the lower end of the protective cover 16.

[0024] like Figure 3 and Figure 4 As shown, the support frame 15 is fixedly installed on the inner wall of the collection tank 14 and is also fixedly installed on the discharge pipe 12 and the fixing plate 11.

[0025] In practical use, the control motor 6 drives the fine grinding ring 8 on the rotating disk 7 to rotate. At this time, the threaded rod 9 is fixed. The fine grinding ring 8 and the threaded rod 9 rotate relative to each other to form a fine grinding channel. The pulverized pulp is then added to the feed hopper 13 through the protective cover 16 and flows into the feed pipe 12 below the feed hopper 13. The threaded rod 9 rotates in the feed pipe 12, and the thread on the threaded rod 9 pushes the pulp in the feed pipe 12 downward, so that the gap between the fine grinding ring 8 and the threaded rod 9 can flow. At this time, the fine grinding ring 8 and the threaded rod 9 refine the pulp and then flow out from the gap between the fine grinding ring 8 and the threaded rod 9 at the end to the bottom of the collection tank 14 for collection. Then it is discharged through the discharge pipe 17 to make special paper. The above is the entire process of using the pulp beating and fine grinding device for special paper production.
