[0002] In industrial production and various material processing processes, it is necessary to pre-mix multiple material particles, which generally involves the use of raw material particle mixing devices.
[0003] Existing mixing devices use vacuum pumps to draw various raw material particles into a mixing tank for mixing. However, mixing is performed directly after the materials are input without pre-mixing, which can easily cause small parts of the materials to agglomerate, resulting in incomplete subsequent mixing and affecting the uniformity and quality of the mixture. Simple mixing devices cannot meet the strict requirements for material uniformity, thus limiting the improvement of product performance and quality.
[0004] Therefore, it is necessary to provide a new mixing device to solve the above-mentioned technical problems. Utility Model Content

[0012] Preferably, a motor is installed and connected to the upper shell wall of the collecting tank, and a vertical shaft is fixedly connected to the output end of the motor, and the vertical shaft is rotatably connected to the vertical pipe.
[0013] Compared with related technologies, the mixing device provided by this utility model has the following beneficial effects:
[0014] 1. This utility model uses the rotation of a pre-dispersion disc and multiple dispersion tubes to initially subdivide the input material, and uses the centrifugal force generated by the rotation to uniformly premix the subdivided material. This premixing method effectively avoids the agglomeration of small parts of the material, lays a good foundation for the subsequent stirring process, makes the final stirring more thorough, greatly improves the mixing effect of the material, and can achieve more uniform mixing for different solid materials, providing high-quality mixed materials for the production process.
[0015] 2. This utility model drives the vertical shaft to rotate through the motor output end, which in turn drives the gear to rotate the external gear ring that meshes with it. The external gear ring drives the pre-dispersing disc to rotate relative to the built-in ring frame. The connecting pipe at the upper end of the pre-dispersing disc rotates stably relative to the rotary joint, which ensures that the pre-dispersing disc can drive multiple dispersing pipes to rotate very stably while dispersing materials in the collection tank.

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1 to 3A mixing device includes: a mixing chamber 1, on which a gas supply pipe 11 is provided; a collection tank 2 is provided at the upper end of the mixing chamber 1; a collection chamber 3 is fixedly connected above the collection tank 2; and multiple conveying pipes 31 are fixedly connected to the collection chamber 3; a pre-mixing mechanism, including a pre-dispersion disc 4, which is located inside the collection tank 2; a connecting pipe is provided at the middle of the pre-dispersion disc 4; a rotary joint 41 is installed at the upper end of the connecting pipe; a connecting pipe is provided at the lower end of the collection chamber 3; the rotary joint 41 is connected to the lower end of the connecting pipe; and multiple dispersing pipes 42 are provided on the lower shell wall of the pre-dispersion disc 4.
[0022] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the multiple dispersion tubes 42 are arranged in an equidistant ring.
[0023] It should be noted that the pre-dispersion disc 4 drives multiple dispersion tubes 42 to rotate simultaneously. The input material is pre-divided by the multiple dispersion tubes 42, and the centrifugal force generated by the rotation of the pre-dispersion disc 4 allows the subdivided material to be pre-mixed evenly, so as to effectively prevent small parts of the material from agglomerating.
[0024] refer to Figure 2 and Figure 3 As shown, the inside of the collection tank 2 is equipped with a driving mechanism, which includes an outer gear ring 5. The outer gear ring 5 is fixedly connected to the outer side wall of the pre-dispersion disk 4. A gear 51 is provided on one side of the outer gear ring 5, and the gear 51 meshes with the outer gear ring 5.
[0025] It should be noted that the outer gear ring 5 drives the pre-dispersion disc 4 to rotate relative to the inner ring frame 6, and the discharge raw materials can be mixed evenly under the action of centrifugal force.
[0026] refer to Figure 2 and Figure 3 As shown, the inside of the collection tank 2 is provided with an internal ring frame 6, the pre-dispersion disc 4 is rotatably connected to the internal ring frame 6, and the side wall of the internal ring frame 6 is provided with a secondary shell 61.
[0027] refer to Figure 3 As shown, the inner wall of the built-in ring frame 6 is provided with an inner groove, the outer gear ring 5 is located in the inner groove of the built-in ring frame 6, and the gear 51 is located inside the sub-shell 61.
[0028] It should be noted that gear 51 and external gear ring 5 are respectively located inside the sub-shell 61 and the inner ring frame 6 to prevent the adhesion of particulate raw materials.
[0029] refer to Figure 3 As shown, a vertical tube 7 is provided at the middle position of the sub-shell 61, and two connecting ears 71 are symmetrically provided on the side wall of the inner ring frame 6. Both connecting ears 71 are fixedly connected to the inner wall of the collecting tank 2.
[0030] It should be noted that the vertical tube 7 can limit the rotation of the vertical shaft 81.
[0031] refer to Figure 2 and Figure 3 As shown, a motor 8 is installed and connected to the upper shell wall of the collection tank 2. The output end of the motor 8 is fixedly connected to a vertical shaft 81, which is rotatably connected to the vertical pipe 7.
[0032] It should be noted that: starting the motor 8 causes its output end to drive the vertical shaft 81 to rotate, which in turn drives the gear 51 to drive the external gear ring 5 that meshes with it to rotate, which serves as the main driving force to drive the pre-dispersion disk 4 to rotate.
[0033] The working principle of the mixing device provided by this utility model is as follows: The motor 8 is started so that its output end drives the vertical shaft 81 to rotate, which drives the gear 51 to drive the outer gear ring 5 that meshes with it to rotate. The outer gear ring 5 drives the pre-dispersion disk 4 to rotate relative to the inner ring frame 6, so that the connecting pipe at the upper end of the pre-dispersion disk 4 rotates stably relative to the rotary joint 41. The pre-dispersion disk 4 drives multiple dispersion tubes 42 to rotate simultaneously, so that the material input by the vacuum pump (existing technology) can be pre-divided by multiple dispersion tubes 42. In addition, the centrifugal force generated by the rotation of the pre-dispersion disk 4 can make the subdivided material uniformly pre-mixed, so as to effectively avoid the agglomeration of small parts of the material and ensure that the subsequent stirring is more thorough.
[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
