Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, and in particular to a mixing shaft for mixing construction materials and a twin-shaft mixer equipped with the mixing shaft. More specifically, this invention focuses on the number of installation positions of the mixing components on the mixing shaft and the phase and direction of the mixing components at each installation position, i.e., their arrangement. Background Technology

[0002] Twin-shaft mixers have been widely used for mixing construction materials. In a twin-shaft mixer, multiple mixing components are fastened to two horizontally arranged shafts by means of threaded connections. Wear-resistant mixing blades are fastened to the ends of the mixing components by means of threaded connections. The two synchronously rotating mixing shafts and the mixing components connected to them form a continuous or intermittent spiral structure. The material is pushed by the mixing components installed at a specific angle, resulting in intricate axial and inter-shaft movements. These material movements can be simplified as a relay transmission between adjacent mixing components. These material movements form two types of cyclic motion: small inter-shaft cyclic motion (including unidirectional reciprocating, triangular, and quadrilateral cyclic motions) and large axial closed cyclic motion. The two types of cyclic motion described above form convection and diffusion motion, generating strong stirring effects such as convection, shearing, compression, tumbling, and throwing. The material achieves macroscopic and microscopic homogeneity in the intense relative motion. The intensity of the small-scale inter-shaft cyclic motion depends on the phase difference between local adjacent stirring components, while the intensity of the large-scale axial cyclic motion depends on the number of stirring component installation positions on the stirring shaft and the phase and direction relationship of the stirring components at each installation position, i.e., the arrangement rhythm. The arrangement of the stirring components is a key factor determining the stirring quality and efficiency of the twin-shaft agitator.

[0003] Currently, common twin-shaft agitators have several phase angles between adjacent agitator components, including 90° (square shaft), 60° (hexagonal shaft), and 45° (octagonal shaft). Among them, agitators with a 45° phase angle (octagonal shaft) have a relatively short development history, and the industry has limited exploration and practice of their arrangement rules. A landmark high-efficiency arrangement has not yet appeared.

[0004] The existing arrangement of mixing components in 45° phase angle (octagonal shaft) twin-shaft mixers currently suffers from three typical defects: First, the arrangement of mixing components on the mixing shafts is discontinuous, resulting in a sluggish (or unclear) transmission rhythm, making it difficult to form effective cyclic motion and leading to low mixing efficiency. Second, the overall arrangement of mixing components on a single mixing shaft is unbalanced, causing significant periodic shaking of the mixing tower during equipment operation, posing a structural safety risk. Third, the inconsistent arrangement rhythm of mixing components on the two mixing shafts results in significant differences in axial conveying capacity, leading to material congestion and accumulation in local areas within the mixer. The material level in these areas rises accordingly, and the mixing components are submerged in material for extended periods, causing wear rates far exceeding normal levels. Their service life is reduced to only 30% of the average level, and the mixing time is also prolonged, even resulting in uneven mixing. Therefore, there is an urgent need for innovative design of the arrangement of mixing components on the mixing shafts of existing 45° phase angle (octagonal shaft) twin-shaft mixers. Summary of the Invention

[0005] The technical problems to be solved by this invention are: low mixing efficiency caused by discontinuous arrangement of mixing components on the mixing shaft and slow transmission rhythm; periodic shaking of the building caused by unbalanced arrangement of mixing components on a single mixing shaft; and significant differences in axial conveying capacity, local material congestion, and abnormal wear of mixing components caused by inconsistent arrangement rhythm of mixing components on two mixing shafts.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a mixing shaft and a twin-shaft mixer for mixing construction materials, comprising: a mixing shaft I and a mixing shaft II, wherein multiple mixing components are installed on the mixing shaft I and the mixing shaft II;

[0007] Preferably, the stirring assembly is Figure 2 The right-hand single stirring assembly shown, or Figure 3 The left-facing single stirring assembly shown, or Figure 4 The right-facing opposing stirring assembly shown, or Figure 5 The left-facing opposing stirring assembly shown, or Figure 6 The left and right opposing stirring components are shown; Figure 2 The right-hand single-stirring assembly shown and Figure 3 The left-side single-unit stirring assembly shown is an unbalanced stirring assembly; Figure 4 The right-facing opposing stirring assembly shown Figure 5 The left-facing opposing stirring assembly and Figure 6 The left and right opposing stirring components shown are all self-balancing stirring components;

[0008] Preferably, the stirring components installed on the stirring shaft I and stirring shaft II are mainly composed of two or more spirally continuous arrangement structures.

[0009] Preferably, the arrangement of the stirring components on stirring shaft I and stirring shaft II meets the requirements of single-shaft overall dynamic balance, that is, each unbalanced stirring component is balanced by another unbalanced stirring component with a phase difference of 180°.

[0010] Preferably, the stirring components on stirring shaft I and stirring shaft II are arranged in a completely synchronized rhythm with a phase difference of 180°. That is, the stirring components on stirring shaft II are arranged such that the set of stirring components on stirring shaft I rotates 180° around the plumb line passing through the geometric center point of the mixing pot, and then rotates 180° around the axis center line. The axial conveying capacity of stirring shaft I and stirring shaft II is completely equal, but the directions are opposite.

[0011] The beneficial effects of this invention are:

[0012] This invention takes into account both large axial circulation motion and small inter-shaft circulation motion, solving the problem of low mixing efficiency caused by discontinuous arrangement of mixing components and sluggish (or unclear) transmission rhythm; effectively avoiding periodic shaking of the building caused by unbalanced arrangement of mixing components on a single mixing shaft; and completely eliminating problems such as significant differences in axial conveying capacity, local material congestion, and abnormal wear of mixing components caused by inconsistent arrangement rhythm of mixing components on two mixing shafts.

[0210] The phase and direction relationship (i.e., the arrangement rhythm) of the stirring components at each installation position on stirring shaft II is the same as that of stirring shaft I, and the phase difference between the two shafts is 180°.

[0211] The above 11 embodiments are the results of optimization based on the principles of simplification and cost from nearly a hundred effective layout schemes; they cover a series of single-axis installation position number implementation schemes from 5 to 15, which can support the development needs of mixing equipment for various construction materials with different properties;

[0212] The advantages of this invention are as follows: The stirring components on a single stirring shaft are mainly composed of two or more spirally arranged continuous structures. During stirring, the stirring components that make up each spiral arrangement advance continuously, accelerating the axial movement rhythm. This solves the problem of low stirring efficiency caused by discontinuous arrangement of stirring components and sluggish (or unclear) transmission rhythm. The arrangement of stirring components on a single stirring shaft meets the overall dynamic balance requirements of the single shaft, that is, each unbalanced stirring component is balanced by another unbalanced stirring component with a phase difference of 180°. Based on this, the periodic shaking of the building caused by the unbalanced arrangement of stirring components is eliminated. The arrangement rhythm of stirring shaft I and stirring shaft II is completely consistent, with a phase difference of 180°. That is, the arrangement of stirring components on stirring shaft II is such that the entire assembly of stirring components on stirring shaft I rotates 180° around a plumb line passing through the geometric center point of the stirrer, and then rotates 180° around the octagonal horizontal axis. The axial conveying capacity of stirring shaft I and stirring shaft II is completely equal, but in opposite directions. It forms a balanced, continuous, stable, and closed axial motion cycle, which significantly improves the stirring efficiency. At the same time, the phenomenon of material congestion and accumulation in local areas inside the stirrer disappears, and local abnormal wear is eradicated.

[0213] This invention is the first to use a detailed table of mixing component arrangement to describe the relationship between mixing components. The mixing shaft, installation position, phase, and direction of the mixing components are all identified by numbers and letters. The complex spatial relationships are presented accurately and without error in the simplest and clearest table, providing a convenient, efficient and accurate method of expression for future exploration, innovation and communication. Usually, the most difficult part of arranging mixing components is to judge and avoid mechanical interference conflicts between adjacent mixing components. Using the detailed table of mixing component arrangement, it can be completed quickly by simply checking whether there are duplicate numbers in every two adjacent rows.

[0214] An unexpected discovery during the exploration of arrangement was that the twin-shaft stirrer with a 45° phase angle (octagonal axis) structure transmits rhythm faster and is easier to avoid mechanical interference than the 90° (quadrilateral axis) and 60° (hexagonal axis) structures, showing promising development prospects.

[0215] Typically, the common ratio of the main parameters of twin-shaft agitators is 1.25. In the serialization design, three model combinations with the same cross-section but different lengths are used, namely the second embodiment (14 installation positions), the fifth embodiment (11 installation positions), and the seventh embodiment (9 installation positions), or three model combinations with the same cross-section but different lengths are used, namely the fifth embodiment (11 installation positions), the seventh embodiment (9 installation positions), and the ninth embodiment (7 installation positions). The fill factor is close, and the length-to-width ratio is easy to control, which can form an ideal serialization planning layout.

[0216] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
