DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] Embodiment 1

[0023] like Figure 1-Figure 2As shown, a large-diameter polygonal cantilever bracket, the main body of which is composed of a polygonal rotating bed frame 1 and a power source bracket 2 connected to the outer periphery of the polygonal rotating bed frame 1, wherein the polygonal rotating bed frame 1 for bearing weight is a hexagonal frame. Compared with a quadrilateral square bracket, the hexagonal frame has more fulcrums and better stability. The bracket can reduce shaking during operation and is less likely to tilt. The power source bracket 2 is used to carry a power device. In this embodiment, the power device is a belt-driven motor, but is not limited to a belt-driven motor. The top surface of the power source bracket 2 is lower than the top surface of the hexagonal frame. The significance of this step is to make the power source bracket 2 located on the power source bracket 2 The output end of the device can be connected to the rotating bed more stably and efficiently. The hexagonal frame mainly includes an annular base plate 10. Six columns 11 are evenly distributed in a circle with the axis of the annular base plate 10 on the upper surface of the annular base plate 10. It is a regular hexagon when viewed from above. The tops of two adjacent columns 11 are connected by a transverse tie rod 12 to enhance the structural strength and provide a support platform for the rotating bed. The power source bracket 2 is a cantilever bracket, and at least part of the power source bracket 2 is connected to the outer facades of two adjacent columns 11. The suspended end of the power source bracket 2 and at least one column 11 are connected by an inclined reinforcing rod 20, and it is a stable triangular structure when viewed from the side.

[0024] The suspended end of the power source bracket 2 and the facades of the two adjacent columns 11 are connected by inclined reinforcing rods 20, one end of the inclined reinforcing rod 20 is connected to the suspended end of the power source bracket 2, and the other end is connected to the facade of the column 11, the purpose of which is to strengthen the load-bearing capacity of the power source bracket 2. This design effectively distributes the load of the power source bracket 2 evenly to the adjacent columns 11. Through the connection of the inclined reinforcing rods 20, not only the load-bearing capacity of the entire structure is improved, but also the lateral force resistance performance of the system is enhanced.

[0025] The power source bracket 2, the inclined reinforcing rod 20 and the column 11 enclose a triangular space 21. The geometric characteristics of the triangle enable the force to be evenly distributed to each part of the structure. Whether under static load or dynamic load, this structure can effectively reduce stress concentration points and avoid local structural damage. This design is conducive to the durability of the overall equipment and reduces maintenance frequency and maintenance costs.

[0026] A positioning plane 22 is provided on the top of the power source bracket 2, and the positioning plane 22 is vertically distributed with the column 11. In this embodiment, the power device is fixedly connected to the positioning plane 22 by bolts, and bolt through holes for the bolts to pass through are provided on the positioning plane 22.

[0027] One end of the power source bracket 2 connected to the corresponding column 11 has an inclined matching surface 13, and the power source bracket 2 is fixed on the inclined matching surface 13 by welding, and the two power source bracket 2 rods are parallel to each other.

[0028] In this embodiment, the power source bracket 2 is connected to the upper middle outer surface of the column 11 .

[0029] The column 11 is any one of a square column, a triangular column and a circular column. In this embodiment, the column is a square column, which provides excellent bending resistance and stability. Since the square cross-section has the same geometric characteristics in all directions, the column can evenly bear loads from different directions, reducing the risk of structural deformation under longitudinal and transverse force conditions.

[0030] The transverse tie rod 12 is any one of angle iron, T-shaped iron and square tube. In the present embodiment, the transverse tie rod 12 is angle iron, and the L-shaped cross section of the angle iron can effectively resist the effect of the transverse force and enhance the overall stability of the structure.

[0031] A slide rail 23 is provided on the positioning plane 22 , and the provision of the slide rail 23 is conducive to the disassembly and maintenance of the power device.

[0032] Embodiment 2

[0033] The structure and principle of this embodiment are basically the same as those of the first embodiment, and the difference lies in that, in contrast to the large-diameter polygonal cantilever bracket of the first embodiment, the high-gravity rotating bed of this embodiment includes a large-diameter polygonal cantilever bracket.

[0034] The supergravity bed of this embodiment is a gas-liquid contact device, which can be widely used in gas-liquid contact occasions such as absorption, distillation, chemical reaction and nano material preparation in chemical, petrochemical, biochemical, pharmaceutical, metallurgical and light industries.

[0035] The characteristic of the supergravity field bed is its small size, and it is known as the "transistor" in chemical equipment. Before the present invention was made, most of the supergravity field rotating beds in the prior art had the entire rotor rotating together, and the gas and liquid were in countercurrent contact inside the rotor under a centrifugal force far greater than gravity. There are many kinds of structures inside the rotor of the existing rotating bed, but the main ones are porous medium fillers such as metal wire mesh and plate fillers. Since the contact time between the gas and liquid phases in the filler is too short, it is not conducive to contact and mass transfer between the gas and liquid phases. The liquid is difficult to distribute evenly, resulting in a gas-liquid short circuit or the liquid forming a channel flow, which reduces the mass transfer efficiency. Since the rotor rotates with the shaft, it is difficult for the existing rotating bed to solve the problem of intermediate feeding in the continuous distillation operation of a single rotating bed. At least two rotating beds are required for continuous distillation operation.

[0036] Embodiment 3

[0037] The structure and principle of this embodiment are basically the same as those of the first embodiment, and the difference lies in that, with respect to the power source bracket of the first embodiment, this embodiment provides a new power source bracket design.

[0038] like Figure 3As shown, in this embodiment, the power source bracket 2 is connected to the adjacent column 11 in an upper and lower movable manner. The advantage is that this upper movable design simplifies the installation process, allowing the construction party to have greater flexibility during installation or maintenance to adapt to changes in site conditions. In the case of needing to adjust or replace the power source, the operator can more easily perform on-site adjustments and maintenance, reducing downtime.

[0039] At the same time, the inclined reinforcing rod 20 connected to the power source bracket 2 and the adjacent column 11 is fixedly connected to the power source bracket 2 at the connecting end, and the part connected to the column 11 at the other end is connected in the same manner as the above-mentioned power source bracket 2. The power source bracket 2 and the inclined reinforcing rod 20 are respectively connected to the column 11 through a locking buckle of a movable structure, such as a tightening bolt, and a groove for the tightening bolt to be buckled is provided on the column 11.

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
