Description

Technical Field

[0001] The utility model relates to a variable-angle stirrer, belonging to the field of stirring equipment. Background Art

[0002] In daily production activities, for different media in a stirring kettle, the effects achieved by stirring are also different. For high-viscosity media, stirring in the form of a backward sweep is usually used to enhance the up-and-down disturbance to achieve the purpose of full mixing and reaction; for low-viscosity media, paddle stirring is usually used to improve the horizontal mixing force. Currently, the commonly used stirring blades in a stirring kettle are fixed, usually fixed on the shaft through a keyway, and the stirring angle and stirring form cannot be changed. When changing the medium, it is often difficult to achieve an ideal stirring effect, and problems such as increased energy consumption will also occur. Existing variable-angle stirrers have problems of complex design and non-durable structure. The angle-changing component of the stirring paddle cannot effectively lock the angle of the stirring paddle, and the angle of the stirring paddle constantly changes during the stirring process, affecting the stirring efficiency; and once a mechanical part inside the stirring shaft fails, the entire stirrer needs to be completely disassembled and replaced, which is time-consuming and laborious. Content of the Utility Model

[0003] To achieve the above object, the utility model provides the following technical solutions:

[0004] A variable-angle stirrer includes a worm and worm gear regulator, a horizontal reducer, a hollow stirring shaft, an adjusting shaft, and a stirring paddle. The horizontal reducer is connected to the hollow stirring shaft. The worm and worm gear regulator is fixed above the horizontal reducer. The adjusting shaft is arranged in the inner cavity of the hollow stirring shaft. One end of the adjusting shaft is connected to the worm and worm gear regulator, and the other end is fixed with a first bevel gear. The bottom of the hollow stirring shaft is connected with a bearing box. A positioning bearing is fixedly embedded inside the bearing box. The inner ring of the positioning bearing is fixedly penetrated with a stirring paddle connecting shaft. One end of the stirring paddle connecting shaft is placed inside the bearing box and fixed with a second bevel gear, and the other end passes through the bearing box to connect the stirring paddle. The second bevel gear meshes with the first bevel gear. A skeleton seal is provided between the bearing box and the stirring paddle connecting shaft.

[0005] The hollow stirring shaft is divided into an upper half shaft and a lower half shaft, and the upper half shaft and the lower half shaft are connected by a coupling. The upper part and the lower part of the hollow stirring shaft are connected by a coupling, which is convenient for cleaning and maintenance inside the shaft. The worm and worm gear regulator adopts a worm and worm gear structure, and the adjusting shaft has a locking effect through the worm and worm gear structure.

[0006] Preferably, the stirring paddle is connected to the stirring paddle connecting shaft by a flange. The paddle part and the stirring paddle connecting shaft are connected by a flange, and the stirring form can be replaced

[0007] Preferably, a stabilizing bearing is sleeved outside the adjusting shaft. The inner ring of the stabilizing bearing is fixedly connected to the adjusting shaft, and the outer ring is fixedly connected to the inner wall of the hollow stirring shaft.

[0008] The regulator shaft is located inside the hollow stirring shaft. The stirring inclination angle is controlled by the first bevel gear driving the second bevel gear. The paddle part and the stirring paddle connecting shaft are connected by a flange, and the stirring form can be replaced. When stirring different media, the stirring paddle can be replaced, and at the same time, the angle of the paddle can be changed. For example, when stirring high-viscosity media, the stirring cut-in angle can be adjusted to be smaller to make it have a larger radial force and increase the up-and-down disturbance of the media; when stirring low-viscosity media, the stirring cut-in angle can be adjusted to be larger to enhance its axial force and make the media mix evenly.

[0009] The beneficial effects of the present utility model are as follows:

[0010] The present utility model has a wide range of applications. It can adjust the stirring form and the cut-in angle according to different media to ensure the mixing and reaction effects of the media. Compared with the traditional stirring with an unchangeable angle, adjusting the angle according to the media can also save power consumption and cost. The hollow stirring shaft is divided into two parts and connected by a coupling, which is convenient for cleaning and maintenance inside the shaft. The worm and worm gear type regulator can be self-locked during stirring, and the angle of the stirring paddle will not shift. Description of the Drawings
