However, the material itself contains a lot of water, and if dehydration is carried out directly by high-speed rotation, it will consume a lot of energy, and the dehydration efficiency may not be fast. Moreover, during the dehydration process, the drain hole is easily blocked by impurities contained in the material, thereby reducing the dehydration efficiency. Utility Model Content

These centrifugal dehydration devices for polyvinyl butyral resin are all driven by a motor and use centrifugal force generated by high-speed rotation to dehydrate the material. However, the material itself contains a large amount of water. If dehydration is carried out directly by high-speed rotation, it will consume a lot of energy and the dehydration efficiency may not be fast.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 - Figure 4 A centrifugal dehydration device for polyvinyl butyral resin includes a dehydration tank 1 and a drain pipe 11 fixedly installed on the axial side wall of the dehydration tank 1. A valve 12 is provided on the axial side wall of the drain pipe 11. The dehydration tank 1 has a first chamber 13 and a second chamber 14. The drain pipe 11 is located on the second chamber 14. A centrifugal assembly 2 for centrifuging and dehydrating the material is provided on the second chamber 14. A pressing assembly 3 for pressing the water in the material is provided at the upper end of the dehydration tank 1. A cleaning assembly 4 is provided on the second chamber 14.

[0023] The centrifuge assembly 2 includes a drive motor 21 fixedly installed on the first chamber 13. A rotating shaft 22 is fixedly installed on the output end of the drive motor 21. A circular material frame 23 is fixedly installed on the axial side wall of the rotating shaft 22. Four reinforcing rods 24 are fixedly installed between the circular material frame 23 and the rotating shaft 22. A connecting plate 25 is fixedly installed on the second chamber 14. A circular groove 26 is provided on the connecting plate 25. The circular groove 26 and the circular material frame 23 are slidably connected. A stirring rod 27 is rotatably installed on the axial side wall of the rotating shaft 22. The stirring rod 27 can stir the material, thereby further improving the dehydration effect. Several drainage holes 28 are provided on the circular material frame 23.

[0024] The pressing assembly 3 includes a fixing plate 31 fixedly installed on the side wall of the dehydration tank 1. A base 32 is fixedly installed on the upper end of the fixing plate 31. A first sliding groove 33 is provided on the base 32. A support plate 34 is rotatably installed on the first sliding groove 33. A telescopic cylinder 35 is fixedly installed on the lower end of the support plate 34. A connecting rod 36 is fixedly installed on the telescopic end of the telescopic cylinder 35. A pressing plate 37 is fixedly installed on one end of the connecting rod 36. A first slot 38 and a second slot 39 are provided on the pressing plate 37.

[0025] The dimensions of the first slot 38 are matched with the dimensions of the stirring rod 27. When the extrusion plate 37 moves downward, it can extrude the material and squeeze out the water, thereby improving the dehydration efficiency of the material.

[0026] In this embodiment: Initially, the extrusion rod 45 is located at the upper end of the dehydration tank 1. Then, the support plate 34 is rotated, causing the extrusion plate 37 to move out of the upper end of the dehydration tank 1. Next, the material is placed into the circular material frame 23. Then, the extrusion plate 37 is moved back to the upper end of the dehydration tank 1. Then, the telescopic cylinder 35 is activated, causing its telescopic end to drive the connecting rod 36 and the extrusion plate 37 downwards. Because the size of the extrusion plate 37 is slightly smaller than the size of the circular material frame 23, the material is then extruded through the extrusion plate 37, thereby removing the moisture from the material. The extrusion process improves dehydration efficiency. Then, the extrusion plate 37 is moved upward slightly by the telescopic cylinder 35. The drive motor 21 is then started, causing the output end of the drive motor 21 to drive the rotating shaft 22 and the circular material frame 23 to rotate on the circular chute 26. The centrifugal force generated by the high-speed rotation can dehydrate the material. At this time, the extrusion plate 37 can prevent the material from being thrown out of the circular material frame 23 during the high-speed rotation. The reinforcing rod 24 between the circular material frame 23 and the rotating shaft 22 can increase the stability of the circular material frame 23 during high-speed rotation.

[0027] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 5The cleaning component 4 includes four second slide grooves 41 formed on the second chamber 14. A sweeping rod 42 is slidably mounted on the four second slide grooves 41. A brush 43 is bonded to the sweeping rod 42. A spring 44 is provided between the sweeping rod 42 and the four second slide grooves 41. Four extrusion rods 45 are fixedly mounted on the upper end of the extrusion plate 37. The size of the second slide grooves 41 will not cause the springs 44 to displace. When the extrusion rods 45 apply pressure to the sweeping rods 42, they can compress the springs 44, so that the brush 43 cleans the drain hole 28.

[0028] The brush 43 is in contact with the outer wall of the circular material frame 23. When the squeezing rod 45 is squeezed by the telescopic cylinder 35, the brush 43 cleans the surface of the circular material frame 23, thereby improving the dewatering efficiency.

[0029] The extrusion rod 45 is located at the upper end of the cleaning rod 42. When the extrusion plate 37 extrudes the material downwards, it can also drive the extrusion rod 45 to extrude the cleaning rod 42, thereby preventing the drain hole 28 from becoming blocked.

[0030] In this embodiment: the material may contain some impurities, which may cause blockage of the drain hole 28 during the dehydration process, thereby reducing the dehydration efficiency. The telescopic cylinder 35 drives the extrusion plate 37 and extrusion rod 45 to move downward, and the extrusion rod 45 applies pressure to the cleaning rod 42, thereby compressing the spring 44 so that the brush 43 cleans the surface of the circular material frame 23. The circular material frame 23 can be cleaned while the material is being extruded and dehydrated, which further improves the dehydration efficiency. Finally, the wastewater is discharged through the valve 12 and the drain pipe 11.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
