The stirring drum is arranged on the support frame to rotate obliquely, and one end of the stirring drum opening is arranged obliquely upward. There is an arc transition between the side wall of the stirring drum and the rear end thereof. A rotating shaft is arranged at the rear end of the stirring drum, and the rotating shaft is driven to rotate by the driving assembly. A plurality of blades are evenly distributed on the inner side wall of the stirring drum, and the blades are all curved plate structures. The direction of each blade is arranged along the axial direction of the stirring drum, and the rear end of each blade is respectively extended to one side of the inner wall of the rear end of the stirring drum, so that each blade is inclined relative to the central axis of the stirring drum.

In this cycle, the material can perform ternary motion in the stirring drum, which can more effectively disperse the agglomerated particles, ensure that the particles can be evenly stirred with the color powder slurry, promote full contact of different components, and improve the uniformity of mixing.

Description

Technical Field

[0001] The invention relates to the technical field of stirring devices, and in particular to a ternary motion stirring reaction device. Background Art

[0002] In the production process of dyeing sand and plastic, it is necessary to stir and mix the fine particle raw materials. Traditional stirring devices such as vertical mixers and horizontal mixers mainly drive the material movement by rotating the main shaft. This stirring method is prone to dead angles, resulting in uneven stirring. The existing drum mixer consists of a horizontal or inclined drum and a drive device. The tumbling and mixing of the materials are achieved through the rotation of the drum. This single horizontal tumbling mixing method will cause the material to continue to stay in place and tumble, causing the material to gradually disperse to both sides, thus failing to achieve a uniform mixing effect. If an inclined drum is used, the material will continue to be transported forward and discharged or concentrated at one end of the drum, ultimately resulting in poor mixing effect. Summary of the invention

[0003] In view of the above problems, the present invention discloses a ternary motion stirring reaction device, which adopts an inclined rotating drum and inclined curved blades to enable the material to perform ternary motion in the rotating drum, thereby achieving a sufficient stirring and mixing effect.

[0004] The specific technical solutions are as follows:

[0010] Furthermore, the angle α between the blade and the axis of the stirring drum is 10° to 15°.

[0011] The beneficial effects of the present invention are embodied in:

[0012] The mixing drum of the present invention adopts an inclined design with the front higher and the rear lower, so that the material in the mixing drum can move backwards as the mixing drum rotates.

This cycle allows the material to perform a ternary motion in the mixing drum, which can more effectively disperse the agglomerated particles, ensure that each particle can be evenly mixed with the color powder slurry, promote full contact between different components, and thus improve the uniformity of mixing.

[0020] Please refer to the attached Figure 1-4 The present embodiment provides a ternary motion stirring reaction device, comprising a support frame 1, a stirring drum 2 and a driving assembly. The stirring drum 2 is arranged on the support frame 1 for tilting and rotating. The front end of the stirring drum 2 is open, and the open end of the stirring drum 2 is tilted upward. The opening structure is adopted to facilitate the feeding of materials into the stirring drum 2. There is an arc transition setting between the side wall of the mixing drum 2 and its rear end. A rotating shaft 21 is set at the center of the rear end of the mixing drum 2. The rotating shaft 21 is driven to rotate by a driving assembly. The driving assembly is connected and fixed to the support frame 1 through a connecting rod 6. A number of blades 3 are evenly distributed on the inner wall of the mixing drum 2. The connection between the blades 3 and the inner wall of the mixing drum is a curved surface. The direction of each blade 3 is set along the axial direction of the mixing drum 2. The rear end of each blade 3 extends to one side of the inner wall of the rear end of the mixing drum 2, and each blade 3 is set obliquely relative to the central axis of the mixing drum 2, and an angle α is formed between each blade 3 and the axis of the mixing drum 2. During the rotation of the mixing drum 2, the material rises with the blade 3, and moves to the front end of the mixing drum 2 under the guidance of the blade 3 and falls, and then rolls down to the rear end of the mixing drum 2, so as to circulate. In this process, the material performs linear motion, curvilinear motion, and rotational motion, that is, ternary motion. Change the flow pattern of the material and form a more complex motion trajectory. This kind of motion trajectory helps the materials to be more evenly distributed during the mixing process, reducing dead corners and stagnation areas. Making the materials move in a complex three-dimensional space can better break up the aggregation of materials and promote full contact between different components, thereby improving the uniformity of mixing.

The active bevel gear 51 is meshed and connected with a driven bevel gear 22 arranged on the rotating shaft 21, so that the motor 5 drives the rotating shaft 21 and the stirring drum 2 to rotate, thereby realizing the drum stirring function.

[0022] In this embodiment, the support frame 1 includes a support 11 and a positioning ring 12. The positioning ring 12 is inclined on the support 11. The positioning ring 12 is sleeved on the front end outer wall of the stirring drum 2 and is rotatably connected to the stirring drum 2 through a bearing. The upper end of the positioning ring 12 is connected to a connecting rod 6. The connecting rod 6 is arranged along the inclination direction of the stirring drum 2 and connected to the mounting shell. The overall structure is simple and compact, and a handle 61 is provided on the connecting rod 6 to facilitate the rapid transportation of the stirring reaction device.

[0023] In this embodiment, the blade 3 adopts a flat plate structure that is wide at the front and narrow at the back, the front end of the blade 3 is arranged along the inner wall of the mixing drum 2, and the rear end of the blade 3 is arranged in an arc transition and extends to the rear inner wall of the mixing drum 2. And the angle α between the blade 3 and the axis of the mixing drum 2 is 10° to 15°.
