Description

Technical Field

[0001] This utility model relates to the field of dispersion devices, and in particular to a fine powder dispersion device for preparing emulsion antioxidants. Background Technology

[0002] Antioxidants are a class of chemical substances that, when present in small amounts in a polymer system, can slow down or inhibit the polymer oxidation process, thereby preventing polymer aging and extending its service life; they are also known as antioxidants. Antioxidants are generally solid powders. If processed into fine powders and then uniformly dispersed in a liquid medium, they can be made into emulsions. Emulsion antioxidants are more convenient to use and have a wider range of applications.

[0003] In the prior art, a Chinese utility model patent with publication number "CN212632470U" and patent name "Fine Powder Dispersion Device for Preparing Emulsion Antioxidants" discloses a dispersion device. This patent describes a technical solution including: "The dispersion device comprises a geared motor, a dispersion cylinder, and a rotating dispersion disc; the rotating dispersion disc comprises a rotating disc and a rotating shaft, the rotating disc being welded to the lower part of the rotating shaft, and the rotating disc having several layers of circumferentially distributed feeding holes; the dispersion cylinder has a disc inside, the disc having several layers of feeding holes consistent with the number of layers and hole positions of the rotating disc, and the number of feeding holes being twice the number of feeding holes; a rotating sleeve is welded into the central hole of the disc; a raised edge is provided on the outside of the cylinder, and the bottom end of the disc is higher than the upper end of the raised edge; the geared motor is mounted and fixed on a motor support frame, the motor support frame is welded to the cylinder, the output shaft of the geared motor is connected to the rotating shaft, the bottom end of the rotating shaft is located inside the rotating sleeve, and a gap is provided between the installed rotating disc and the disc."

[0004] However, in actual use, when the fine powder is fed into the dispersing cylinder and falls onto the low-speed rotating disc, it is dispersed through the discharge holes on the disc. As a result, the fine powder accumulates on the rotating disc located below the feed port, and the fine powder cannot be evenly distributed across the entire rotating disc. This leaves some discharge holes idle, further causing uneven distribution of the fine powder after it is fed. At the same time, the continuous accumulation of fine powder can easily cause blockage of the feed holes on the rotating disc, which will affect the dispersion effect of the fine powder and thus reduce the quality of the emulsion antioxidant preparation.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a fine powder dispersion device for preparing emulsion antioxidants. Utility Model Content

[0006] The main objective of this invention is to provide a fine powder dispersion device for preparing emulsion antioxidants, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A fine powder dispersion device for preparing emulsion antioxidants includes a dispersion cylinder with a feeding port fixedly connected to its top surface. The dispersion cylinder contains a dispersion mechanism, which includes a feeding disc, a horizontal plate, a drive motor, a first pulley, a second pulley, a rotating shaft, a rotating disk, a compression spring, an impact block, a top plate, and a hemispherical block. The feeding disc is fixedly connected inside the dispersion cylinder, and the horizontal plate is fixedly connected to the inner wall of the dispersion cylinder and located above the feeding disc. The rotating shaft is movably connected to the top surface of the dispersion cylinder via a rotating rod on its top surface, and the rotating disk... The first pulley is fixedly connected to the bottom end of the rotating shaft and located between the feeding plate and the horizontal plate. The second pulley is sleeved on the outside of the rotating rod through the fixing hole on the top surface. The drive motor is fixedly connected to the bottom surface of the top mounting seat on one side of the outer wall, and the first pulley is fixedly connected to the output end of the drive motor and movably connected to the second pulley through the belt. The striking block is movably connected to the inside of the rotating shaft through the movable rod on the top surface, and the compression spring is sleeved on the outside of the movable rod. The top plate is fixedly connected to the top end of the movable rod, and the hemispherical block is fixedly connected to one side of the bottom surface of the top plate.

[0009] Furthermore, a mounting base is fixedly installed on the top of the right side wall of the dispersion cylinder, and a mounting hole is opened at the center of the top surface of the dispersion cylinder, and a bearing is fixedly installed in the mounting hole.

[0010] Furthermore, the feeding tray is fixedly installed inside the dispersing cylinder, and a number of feeding holes are opened on the top surface of the feeding tray. A horizontal plate is also fixedly installed on the inner wall of the dispersing cylinder above the feeding tray.

[0011] Furthermore, the drive motor is fixedly mounted on the bottom surface of the mounting base, and a first pulley is fixedly mounted on the top surface of the output end of the drive motor. A fixing hole is opened on the top surface of the second pulley, and the second pulley is fixedly mounted on the outer wall of the rotating rod in a sleeve manner through the fixing hole. A belt is also movably mounted between the first pulley and the second pulley.

[0012] Furthermore, the rotating rod and the bearing are inserted and fixed together, and a rotating shaft is fixedly installed at the bottom end of the rotating rod. A rotating disk is fixedly installed at the bottom end of the rotating shaft, and a discharge hole corresponding to the feeding hole is opened on the top surface of the rotating disk.

[0013] Furthermore, the rotating shaft has an internal cavity communicating with the rotating rod, and the top surface of the rotating rod has a through hole, on which a set of symmetrical guide blocks are fixedly installed.

[0014] Furthermore, a movable rod is fixedly installed on the top surface of the striking block, and the movable rod is inserted into the through hole. A set of symmetrical guide grooves are opened on the outer wall of the movable rod, and the guide block is movably installed in the guide groove. The compression spring is sleeved on the outside of the movable rod and fixedly installed between the top surface of the striking block and the inner top surface of the inner cavity. The top plate is fixedly installed on the bottom surface of the movable rod, and a hemispherical block is fixedly installed on one side of the bottom surface of the top plate.

[0015] Furthermore, a fixing column is fixedly installed on the top surface of the dispersion cylinder and in front of and behind the second pulley, and the top of the fixing column is hemispherical.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, the dispersing mechanism is designed so that after the fine powder is fed into the dispersing cylinder through the feeding port, it falls onto the top surface of the rotating disc. At this time, the drive motor drives the output end to rotate the first pulley, which in turn drives the second pulley to rotate via a belt. The second pulley then drives the rotating shaft to rotate via a rotating rod, which in turn drives the bottom rotating disc to rotate. During the rotation of the rotating disc, the fine powder on the top surface rotates synchronously. When the fine powder accumulated on the top surface of the rotating disc comes into contact with the horizontal plate fixed to the inner wall of the dispersing cylinder, the horizontal plate can statically stir the accumulated fine powder and spread it evenly on the top surface of the feeding disc. When the top surface discharge hole coincides with the discharge hole on the top surface of the bottom feeding disc during the rotation of the rotating disc, the fine powder can fall downwards evenly. At the same time, the top plate moves downwards with the powder. When the rotating rod rotates, it drives the top plate to rotate. After the hemispherical block on one side of the bottom of the top plate rotates and comes into contact with the fixed column on the top surface of the dispersion cylinder, the hemispherical block is squeezed upward by the fixed column and moves upward. The top plate drives the movable rod to move downward through the guide groove and along the guide block from the through hole. The movable rod drives the striking block to move upward in the inner cavity and instructs the compression spring to tighten until the hemispherical block passes the fixed column. Then the compression spring expands and quickly pushes the striking block downward to strike the top surface of the rotating disk. In this way, by intermittently hitting and vibrating the rotating disk, the problem of blockage caused by fine powder accumulation in the discharge hole of the rotating disk can be avoided, thereby effectively improving the dispersion effect of fine powder and ensuring the quality of the prepared emulsion antioxidant.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 6 As shown, a fine powder dispersion device for preparing emulsion antioxidants includes a dispersion cylinder 1, with a feeding port 2 fixedly connected to the top surface of the dispersion cylinder 1. The dispersion cylinder 1 is equipped with a dispersion mechanism 3, which includes a feeding disc 7, a horizontal plate 9, a drive motor 10, a first pulley 11, a second pulley 12, a rotating shaft 15, a rotating disk 17, a compression spring 25, an impact block 26, a top plate 27, and a hemispherical block 28. The feeding disc 7 is fixedly connected inside the dispersion cylinder 1, and the horizontal plate 9 is fixedly connected to the inner wall of the dispersion cylinder 1 and located above the feeding disc 7. The rotating shaft 15 is movably connected to the top surface of the dispersion cylinder 1 via a rotating rod 16 on the top surface, and the rotating disk... 17 is fixedly connected to the bottom end of the rotating shaft 15 and located between the feeding plate 7 and the horizontal plate 9. The second pulley 12 is sleeved on the outside of the rotating rod 16 through the fixing hole 13 on the top surface. The drive motor 10 is fixedly connected to the bottom surface of the top mounting seat 4 on one side of the outer wall. The first pulley 11 is fixedly connected to the output end of the drive motor 10 and is movably connected to the second pulley 12 through the belt 14. The striking block 26 is movably connected to the inside of the rotating shaft 15 through the movable rod 23 on the top surface. The compression spring 25 is sleeved on the outside of the movable rod 23. The top plate 27 is fixedly connected to the top end of the movable rod 23. The hemispherical block 28 is fixedly connected to one side of the bottom surface of the top plate 27.

[0027] like Figure 3As shown, a mounting base 4 is fixedly installed on the top right side wall of the dispersion cylinder 1. The mounting base 4 is used to install and fix the drive motor 10. A mounting hole 5 is opened in the center of the top surface of the dispersion cylinder 1. A bearing 6 is fixedly installed in the mounting hole 5. The bearing 6 installed in the mounting hole 5 is used to cooperate with the rotating rod 16 to realize the rotation operation.

[0028] like Figure 3 As shown, the feeding disc 7 is fixedly installed inside the dispersing cylinder 1, and the top surface of the feeding disc 7 is provided with several feeding holes 8. The fine powder can be evenly distributed to the bottom through the feeding holes 8 on the top surface of the feeding disc 7. A horizontal plate 9 is also fixedly installed on the inner wall of the dispersing cylinder 1 above the feeding disc 7. The horizontal plate 9 can evenly spread the fine powder on the top surface of the rotating disc 17 on the top surface of the rotating disc 17 and prevent the fine powder from clogging and distributing unevenly.

[0029] like Figure 4 As shown, the drive motor 10 is fixedly installed on the bottom surface of the mounting base 4, and the top surface of the output end of the drive motor 10 is fixedly installed with a first pulley 11. The top surface of the second pulley 12 is provided with a fixing hole 13, and the second pulley 12 is fixedly installed on the outer wall of the rotating rod 16 in a sleeve manner through the fixing hole 13. A belt 14 is also movably installed between the first pulley 11 and the second pulley 12. After the drive motor 10 is turned on to drive the output end to drive the second pulley 12 to rotate, the second pulley 12 can drive the first pulley 11 to rotate through the belt 14, and the first pulley 11 can drive the rotating rod 16 to rotate.

[0030] like Figure 4 As shown, the rotating rod 16 and the bearing 6 are inserted and fixed together, and the bottom end of the rotating rod 16 is fixedly installed with a rotating shaft 15. The bottom end of the rotating shaft 15 is fixedly installed with a rotating disk 17, and the top surface of the rotating disk 17 is provided with a discharge hole 18 corresponding to the discharge hole 8. After the rotating rod 16 rotates in the bearing 6, it will drive the mounting hole 5 to rotate. The rotating shaft 15 will drive the rotating disk 17 to rotate, so that the discharge hole 18 on the rotating disk 17 coincides with the discharge hole 8 on the top surface of the discharge disk 7, allowing the fine powder spread on the top surface of the rotating disk 17 to fall evenly to the bottom.

[0031] like Figure 5 and Figure 6 As shown, the rotating shaft 15 has an inner cavity 20 that communicates with the rotating rod 16. The inner cavity 20 is used to cooperate with the up and down movement of the striking block 26. The top surface of the rotating rod 16 has a through hole 21. The through hole 21 can ensure the up and down movement of the movable rod 23. A set of symmetrical guide blocks 22 are fixedly installed on the inner wall of the through hole 21. The guide blocks 22 are used to cooperate with the movable rod 23 to play a guiding role.

[0032] like Figure 5 and Figure 6As shown, a movable rod 23 is fixedly installed on the top surface of the striking block 26, and the movable rod 23 is inserted into the through hole 21. A set of symmetrical guide grooves 24 are opened on the outer wall of the movable rod 23, and the guide block 22 is movably installed in the guide groove 24. The compression spring 25 is sleeved on the outside of the movable rod 23 and fixedly installed between the top surface of the striking block 26 and the inner top surface of the inner cavity 20. The top plate 27 is fixedly installed on the bottom surface of the movable rod 23, and a hemispherical block 28 is fixedly installed on one side of the bottom surface of the top plate 27. When the rotating rod 16 rotates, the hemispherical block 28 on the bottom surface of the top plate 27 is squeezed. After pressing, the top plate 27 will be pushed upward. The top plate 27 will drive the movable rod 23 to move upward through the guide groove 24 and along the guide block 22 from the through hole 21. The movable rod 23 will drive the bottom striking block 26 to move in the inner cavity 20 and force the compression spring 25 to tighten until the hemispherical block 28 is no longer blocked. Then the compression spring 25 will extend and cause the striking block 26 to move downward quickly and strike the top surface of the rotating disk 17, causing the rotating disk 17 to vibrate. This can prevent the discharge hole 18 on the top surface of the rotating disk 17 from being blocked due to excessive fine powder.

[0033] like Figure 5 and Figure 6 As shown, a fixing column 19 is fixedly installed on the top surface of the dispersion cylinder 1 and in front of and behind the second pulley 12, and the upper part of the fixing column 19 is hemispherical. The fixing column 19 plays a role in resisting the squeezing and pushing of the hemispherical block 28.

[0034] The specific operating principle of the dispersing mechanism 3 in conjunction with the dispersing cylinder 1 is as follows:

[0035] The dispersing cylinder 1 is pre-installed above the mixing or processing equipment. After fine powder is fed into the dispersing cylinder 1 through the feeding port 2, the fine powder will fall and accumulate on the top surface of the rotating disk 17 below the feeding port 2. At this time, the drive motor 10 installed on the bottom surface of the mounting base 4 will drive the first pulley 11 installed on the top surface to rotate. The first pulley 11 will drive the second pulley 12 to rotate through the belt 14. The second pulley 12 is fixed to the top of the outer wall of the rotating rod 16 through the fixing hole 13 opened on the top surface. Therefore, the second pulley 12 will drive the rotating rod 16 to rotate in the bearing 6 installed in the mounting hole 5 opened on the top surface of the dispersing cylinder 1. The rotating rod 16 will drive the rotating shaft at the bottom. 15 rotates, and the rotating shaft 15 drives the rotating disk 17 at the bottom to rotate. During the rotation of the rotating disk 17, when the fine powder accumulated on the top surface of the rotating disk 17 comes into contact with the horizontal plate 9 installed on the top surface of the rotating disk 17 on the inner wall of the dispersing cylinder 1, the horizontal plate 9 can push the fine powder and flatten it, spreading it evenly on the top surface of the rotating disk 17. As the rotating disk 17 continues to rotate, the discharge hole 18 on the top surface coincides with the discharge hole 8 on the top surface of the feeding disk 7 installed inside the dispersing cylinder 1. The fine powder will then pass through the discharge hole 18 and the discharge hole 8 and be evenly dispersed into the material in the mixing or processing equipment below for processing. At the same time, as the rotating rod 16 drives the rotating shaft 15 to rotate, the rotating shaft 15 rotates... The top plate 27 above shaft 15 will rotate synchronously. After the top plate 27 rotates, the hemispherical block 28 installed on one side of its bottom surface will be blocked by the hemispherical fixed column 19 installed on the top surface of the dispersion cylinder 1. Under the continuous rotational extrusion force, the hemispherical block 28 will push the top plate 27 upward. The top plate 27 will drive the movable rod 23 on the bottom surface to move upward through the guide groove 24 opened on the outer wall and along the guide block 22 from the through hole 21 opened on the top surface of the rotating rod 16. At this time, the movable rod 23 will drive the striking block 26 installed at the bottom end to move upward in the inner cavity 20 opened in the rotating shaft 15, and force the compression spring 25 fitted outside the movable rod 23 to retract. During operation, once the hemispherical block 28 has passed the fixed column 19 and is no longer blocked by it, the compression spring 25 will elastically extend and restore its original position, pushing the striking block 26 to move downwards quickly. This causes the striking block 26 to strike the top surface of the rotating disk 17 and generate vibration, shaking off the fine powder from the clogged discharge hole 18 on the top surface of the rotating disk 17. By continuously spreading the accumulated fine powder evenly on the top surface of the rotating disk 17 and intermittently striking and vibrating the rotating disk 17, the problem of fine powder clogging the top surface of the rotating disk 17 and the discharge hole 18 can be effectively prevented. This allows the fine powder to be evenly dispersed into the processing equipment, thereby ensuring the quality of the prepared emulsion antioxidant.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
