Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically to a concentric double-shaft dispersion mixing tank. Background Technology

[0002] In the process of material mixing and production, it is often necessary to use a mixing vessel to mix various materials, so that the coating inside the mixing vessel is more uniform and fine. The mixing vessel includes a vessel body and a stirring shaft set on the vessel body. The stirring shaft is equipped with a stirring paddle. The materials required for coating production are placed in the vessel body, and the stirring paddle makes the materials evenly mixed.

[0003] There are two main types of stirred tanks: horizontal and vertical. In vertical stirred tanks, the stirring shaft is longitudinally positioned on the tank body. However, during the stirring process of the agitator, the material rotates accordingly. But due to the high viscosity of the material, it cannot be mixed quickly, resulting in uneven mixing. Therefore, existing stirred tanks are designed with the stirring shaft and agitator independent of each other, allowing for separate stirring. However, the corresponding transmission components are often designed on the side of the tank body, occupying a large amount of space. Utility Model Content

[0031] like Figure 1 , Figure 2 The concentric dual-shaft dispersion mixing vessel shown includes a vessel body 1, a main shaft 2 vertically inserted into the top of the vessel body 1, and a concentrically arranged stirring assembly sleeved on the outside of the main shaft 2. A first driving member 11 for driving the main shaft 2 to rotate is arranged above the main shaft 2, and a second driving member 12 for driving the stirring assembly to rotate is arranged on the side of the first driving member 11 and above the vessel body 1.

[0032] The first drive unit 11 includes a first motor and a first reducer. The first reducer is connected to the output end of the first motor, and the output end of the first reducer is connected to the main shaft 2. The second drive unit 12 includes a second motor and a second reducer. The second reducer is connected to the output end of the second motor, and the output end of the second reducer is connected to the bushing 4 via a pulley drive. The first reducer and the second reducer can be replaced or removed according to the actual equipment parameters and requirements.

[0033] This design features a workbench 3 at the top of the vessel body 1. Inside the workbench 3 is a bushing 4 that fits onto the main shaft 2. The bushing 4 is inserted into the vessel body 1 and serves as the primary component for fixing the main shaft 2. A stirring assembly is connected to the bottom of the bushing 4, driving both the bushing 4 and the main shaft 2 to rotate, thus achieving different rotational speeds for the main shaft 2 and the bushing 4 to achieve the desired stirring effect. The first drive component 11 and the second drive component 12 are mounted on the workbench 3, integrating the entire stirring vessel and reducing its footprint.

[0034] Specifically, a mounting base 5 is provided on the top of the vessel body 1, and the worktable 3 is mounted on the mounting base 5. A first bearing 6 is provided between the mounting base 5 and the bushing 4, a second bearing 7 is provided on the top of the bushing 4, and a third bearing 8 is provided on the bottom of the bushing 4.
