TECHNICAL FIELD

[0001] The application relates to the technical field of mixers, in particular to a concentric double-shaft mixer. BACKGROUND

[0002] The concentric double-shaft dispersion mixer is an advanced mixing device, which has two concentric mixing shafts. The core lies in that the double shafts are cooperatively operated to efficiently mix and disperse materials. The two shafts are located at the center of the mixing cylinder, one shaft is mainly responsible for high-speed dispersion, and the other shaft is responsible for low-speed stirring. This unique design can adapt to the processing needs of materials with different properties.

[0003] In addition, the existing patent with the patent number CN 221386117 U discloses a concentric double-shaft dispersion mixer. However, the following problems exist in the actual use of the patent:

[0004] The device realizes the stirring of raw materials by cooperating with the turnover plate during stirring. However, the internal material needs to be cut and scattered by the cutting device during stirring, so that the raw materials can be stirred more uniformly and sufficiently. In addition, the position of the stirring device in the stirring tank is fixed, and the stirring range is also fixed. Therefore, longer stirring time is required to achieve sufficient mixing. To solve the above problems, the application provides a concentric double-shaft mixer. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem of fixed stirring area of the stirring device and achieve sufficient mixing effect, the application provides a concentric double-shaft mixer.

[0006] The concentric double-shaft mixer provided by the application adopts the following technical scheme:

[0007] The concentric double-shaft mixer comprises a stirring tank, a connecting pipe fixedly connected to the top end of the stirring tank, a limiting ring A fixedly sleeved inside the lower part of the connecting pipe, a driving column movably penetrating through the limiting ring A, a stirring fan fixedly connected to the bottom end of the driving column for stirring, a driving rod movably penetrating through the driving column, a plurality of stirring assemblies located in the middle of the stirring fan arranged on the driving rod, a left-right movable limiting rod, a limiting ring B fixedly connected to one end of each of the two limiting rods, a counterweight fixedly arranged at the end of each of the two limiting rods away from the limiting ring B, and a cutting plate fixedly connected to the outer side surface of each of the two counterweights at equal intervals.

[0008] When the driving rod rotates at high speed, the counterweight and the cutting plate gradually move outward under the action of centrifugal force, thereby expanding the stirring range. In addition, the counterweight and the cutting plate can be stopped at different positions under the action of the compression spring according to different rotating speeds of the driving rod, thereby achieving the effect of multi-region stirring.

[0017] Preferably, the output end of the servo motor is fixedly connected with a rotating column rotatably connected with the support sleeve A, and the output end of the driving motor is fixedly connected with the driving rod.

[0018] By adopting the technical scheme, the output end of the servo motor is fixedly connected with the rotating column, and the rotating column is rotatably connected with the support sleeve A. This structure allows the rotating column to rotate under the support of the support sleeve A driven by the servo motor, and the output end of the driving motor is fixedly connected with the driving rod, which means that the driving motor provides rotating power for the driving rod.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. By centrifugal force, the counterweight and the cutting plate move outward, expanding the stirring range, so that the stirring is no longer limited to a fixed area, but can cover a wider area in the stirring tank, thereby improving the comprehensiveness and uniformity of stirring and reducing the problem of insufficient local stirring due to fixed stirring area.

[0025] 2. By high-speed rotation of the driving rod and low-speed rotation of the driving column, and the concentricity of the two stirring shafts, the material is processed under the synergistic action of high-speed dispersion and low-speed stirring, which not only avoids the insufficient stirring caused by single speed stirring, but also realizes more uniform and efficient stirring of the material in a shorter time compared with the traditional stirring device.
