Description

Technical Field

[0001] The utility model relates to the field of stirring equipment, in particular to a mixing tank structure. Background Art

[0002] When mixing high-viscosity materials, paint manufacturers often use single-shaft agitators at low speeds. This type of agitator has low mixing efficiency and poor mixing results. Multi-shaft agitators are also used for mixing. Currently, multi-shaft agitators have multiple shafts arranged in parallel and spaced apart. When mixing materials vertically, this is usually achieved using complexly designed stirring blades. These complex structures are prone to material residue and the overall stirring resistance is high, requiring the agitator to drive a large amount of power.

[0003] Therefore, designing a mixing tank structure with simple structure and low driving power for high viscosity materials is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0006] The upper ends of the first, second and third stirring shafts extend out of the trough body, and the first, second and third bevel gears are fixedly arranged circumferentially respectively.

[0008] The number of the first stirring blades and the third stirring blades is two pairs, and the stirring blades of each pair are axially symmetrically distributed along the corresponding stirring axis.

[0009] The above technical solution has the following beneficial effects:

[0010] 1. The mixing tank structure includes a tank body, and a first stirring shaft, a second stirring shaft, and a third stirring shaft rotatably arranged in the tank body. The tank body is used to provide a space for mixing. Each stirring shaft drives the stirring blades to stir the high-viscosity material by rotating to achieve the purpose of mixing. The bottom of the tank body is an arc surface, and a discharge port is set at the low point of the arc surface bottom, and the opening and closing is controlled by a valve. The tank body with this structure is conducive to the discharge of the mixed material from the tank body through the discharge port after mixing, and can also reduce the residual amount of the mixed material in the tank body, thereby improving the utilization rate of the material. The straight line where the second stirring shaft is located is located on the central axis of the tank body, that is, the second stirring shaft is located at the center of the tank body. A plurality of second stirring blades are arranged at intervals along the length direction on the second stirring shaft, and each second stirring blade is vertically distributed to the second stirring shaft. These second stirring blades are driven by the second stirring shaft to rotate circumferentially to stir and mix the high-viscosity material around the second stirring shaft. The first stirring shaft and the third stirring shaft are axially symmetrically distributed along the second stirring shaft, and the straight lines where they are located are respectively located on the radius extension lines corresponding to the arc surface where the bottom of the groove is located, that is, the first stirring shaft and the third stirring shaft are inclined to extend toward the second stirring shaft, and the first stirring shaft and the second stirring shaft are perpendicular to the tangent line of the projection point. A plurality of first stirring blades and third stirring blades are respectively arranged on the first stirring shaft and the third stirring shaft along the length direction, and each first stirring blade is perpendicular to the first stirring shaft, and each third stirring blade is perpendicular to the third stirring shaft. Each first stirring blade and the third stirring blade are driven by the first stirring shaft and the third stirring shaft to rotate circumferentially, respectively, to stir and mix the high-viscosity materials around the first stirring shaft and the third stirring shaft, and also to form stirring and mixing along the height direction, so as to achieve the purpose of axial and circumferential mixing with a simple structure. Each of the second stirring blades and each of the first stirring blades and each of the third stirring blades are staggered, so that the stirring areas overlap, thereby improving the mixing effect on high-viscosity materials.

[0011] 2. The upper ends of the first, second and third stirring shafts extend out of the trough body, and the first, second and third bevel gears are fixedly arranged circumferentially respectively. The first and third bevel gears are engaged with the second bevel gear. The outward end of the second stirring shaft is connected to the output shaft of the reducer. This driving structure can use a set of reducers to provide power, reducing power requirements, and also making the adjacent stirring shafts rotate in opposite directions, thereby improving the mixing effect of high-viscosity materials.
