Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing and homogenizing devices, and in particular to a mixing and homogenizing device for processing multi-component antioxidants. Background Technology
[0002] As is well known, multi-component antioxidants are additives composed of a variety of components with antioxidant functions. They delay or inhibit the oxidative deterioration of target substances and have wide applications in modern industry, food, chemical industry and energy. Multi-component antioxidants improve the antioxidant effect by using a specific ratio of antioxidants. In particular, powdered antioxidants need to be mixed well before use.
[0003] In Chinese patent CN219765048U, a ribbon mixer is described. The device includes a support plate, a U-shaped container horizontally fixed to the side of the support plate, a discharge pipe fixedly connected to the bottom center of the U-shaped container, a baffle plate movably inserted into the discharge pipe in a horizontal direction, a common shaft rotatably connected to the side of the U-shaped container, a stirring ribbon fixedly connected to the outer wall of the common shaft, a receiving groove on the top of the U-shaped container, a top plate movably inserted into the receiving groove in a horizontal direction, and a limiting component for fixing the top plate at the side edge of the U-shaped container. However, in actual use, the following problems exist:
[0004] During the mixing process of powdered antioxidants, the outer and inner spiral ribbons rotate synchronously. While stirring the material, the inner and outer spiral ribbons push the material to move in opposite directions, forming two material flows in opposite directions, so that the material is mixed evenly. Because the outer and inner spiral ribbons rotate synchronously, the material reaches a stable stirring state after a certain period of time. At certain specific locations, such as the feeding port of newly added material or the center of the cylinder, the material accumulates. The uneven concentration distribution of the material accumulated at these specific locations reduces the mixing efficiency.
[0005] Therefore, a mixing and homogenizing device for processing multi-component antioxidants is proposed. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a mixing and homogenizing device for processing multi-component antioxidants.

The inner wall of the rotary sleeve is connected to the rotating shaft through the rotary transmission assembly. The bottom end of the outer screw rod is fixedly connected to the outer wall of the rotary sleeve.
[0011] The rotary speed change assembly includes a driving plate, a driven plate, and an arc spring. The driving plate is fixedly connected to the rotating shaft, and the driven plate is fixedly connected to the inner wall of the rotating sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This mixing device for processing multi-component antioxidants features a variable rotation speed of the outer spiral plate during material mixing. This prevents material accumulation at a specific position due to constant rotation speeds of the outer and inner spiral plates, which would otherwise lead to uneven material density and reduced mixing efficiency. The inner spiral plate, in addition to mixing, oscillates during material mixing, further enhancing the mixing efficiency. The combined effect of these two mechanisms further prevents material accumulation at a specific position due to constant rotation speeds of the outer and inner spiral plates, thus improving mixing efficiency.

[0035] The work process is as follows:
[0036] S1. In operation, the material to be mixed is first placed into the screw conveyor cylinder 1. The power assembly 3 is then started, and the power assembly 3 drives the rotating shaft 2 to rotate. At this time, the active plate 11 fixedly connected to the rotating shaft 2 pushes the driven plate 12 through the arc spring 13 to rotate the rotating sleeve 10. The rotating sleeve 10 drives the outer screw plate 8 to rotate and stir the material through the outer screw rod 9 fixedly connected to the outer wall of the rotating sleeve 10. During the mixing process, when the resistance of the outer screw plate 8 increases due to the material in contact with it, the active plate 11 and the driven plate 12 cooperate to compress the arc spring. When the compression resistance and thrust reach equilibrium, the outer spiral plate 8 continues to rotate. As the material in contact with the outer spiral plate 8 decreases during the stirring process, the arc spring 13 begins to return to its original position, pushing the driven plate 12 to increase the rotation speed of the outer spiral plate 8. The rotation speed of the outer spiral plate 8 is in a variable state when stirring and mixing the material, while the rotation speed of the inner spiral plate 6 remains constant. This avoids the uneven material density caused by material accumulation at a specific position due to the constant rotation speed of the outer and inner spiral plates, which leads to a decrease in the degree of mixing and thus improves the mixing efficiency.
[0037] S2, during the mixing of materials, the power component 3 drives the rotating shaft 2 to rotate, which in turn drives the base 14 to rotate. The base 14 drives the inner threaded plate 6 to rotate and mix the materials via the inner threaded rod 7. When the resistance of the material on the inner threaded plate 6 increases, the inner threaded plate 6 drives the inner threaded rod 7 to rotate along its own axis. At this time, the inner threaded rod 7 drives the fixed limiting plate 16 on the inner threaded rod 7 to slide and rotate in the fan-shaped limiting groove 18. The limiting plate 16 and the fixed plate 15 cooperate to rotate and compress the torsion spring 17. During the continued mixing process, the resistance of the material on the inner threaded plate 6 decreases, the torsion spring 17 returns to its original state, and drives the inner threaded rod 7 to rotate in the opposite direction. In addition to mixing, the inner threaded plate 6 oscillates during the mixing process. The oscillation of the inner threaded plate 6 further mixes the materials and improves the mixing efficiency.
[0038] S3, when mixing materials, the rotation speed of the outer spiral plate 8 changes continuously, while the inner spiral plate 6 oscillates during the mixing process. The compression state of the material between the outer spiral plate 8 and the inner spiral plate 6 also changes, which avoids the reduction in mixing degree caused by the accumulation of material at a specific position due to the constant rotation speed of the outer and inner spiral plates, thereby improving the mixing efficiency.
[0039] The inner and outer spiral ribbons are divided into multiple segments: inner spiral ribbon plate 6 and outer spiral ribbon plate 8. This divides the spiral ribbon machine cylinder 1 into multiple mixing zones. The differential speed between these zones can further improve the mixing efficiency. The rotary speed change assembly is divided into four groups. The driving plate 11 of the rotary speed change assembly adjacent to the driven plate 12 acts as a limit for the driven plate 12. Dividing the rotary speed change assembly into four groups ensures the rotational speed of the outer spiral ribbon plate 8 while avoiding disrupting the driving effect between the various outer spiral ribbon plates 8. Of course, this can also be adjusted according to factors such as the viscosity and density of the actual material.

Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution.

However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
