A rotating shaft passing through both ends of the housing is provided at the center of the housing. A group of rotors arranged in layers from top to bottom are connected in series on the rotating shaft. The housing is also provided with an intermediate feed port communicating with the baffle ring channel. The rotor is composed of a moving baffle plate fixedly connected to the rotating shaft and a static baffle plate fixedly connected to the housing. The moving baffle ring and the static baffle ring are respectively fixedly connected to the moving baffle plate and the static baffle plate. A group of concentric and differently-diameter moving baffle rings and static baffle rings are arranged opposite to each other to form a zigzag baffle ring channel. First channel openings are provided on both sides at the lower end of the rotor, and a second channel opening is provided at the center of the upper end of the rotor.

[0022] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0023] Embodiment 1

[0024] As Figure 1 shown, the hypergravity bed cylinder body is composed of a cylinder body shell 1. Inside the lower end of the cylinder body shell 1, there is a cylinder body bottom plate 2 that divides the inside of the cylinder body shell 1 into a lower chamber 10 and an upper chamber 11. On the lower surface of the cylinder body bottom plate 2, there is a reinforcing ring 20 located inside the lower chamber 10. The reinforcing ring 20 is located inside the lower chamber 10 on the lower surface of the cylinder body bottom plate 2, which plays a role in strengthening the bottom structure of the cylinder body, increasing the stiffness and strength of the bottom plate to support the gravity of the entire cylinder body and the loads during operation. On the lower surface of the cylinder body bottom plate 2, there are also several radially reinforcing ribs 21 distributed in a circular pattern. In this embodiment, as Figure 3 shown, six evenly distributed radially reinforcing ribs 21 are selected. For example, it can also be in the form of four or five ribs as Figures 4 - 5 shown. The radially reinforcing ribs 21 distributed in a circular pattern are connected to the lower surface of the cylinder body bottom plate 2. Their outer ends are connected to the inner wall of the cylinder body shell 1, and their inner ends are connected to the outer wall of the reinforcing ring 20, which plays a role in strengthening the bottom plate structure and improving the bearing capacity and stability of the cylinder body bottom plate 2. At the lower end of the cylinder body shell 1, there is a reinforcing ring plate 22 connected to the bottom side of the radially reinforcing ribs 21. The reinforcing ring plate 22 is connected to the lower end of the cylinder body shell 1 and is connected to the bottom side of the radially reinforcing ribs 21, which plays a role in supporting and fixing the radially reinforcing ribs 21.

[0025] As Figure 2 shown, there is a ring plate positioning groove 210 on the bottom side of the radially reinforcing rib 21. At least part of the reinforcing ring plate 22 is located in the ring plate positioning groove 210. By placing part of the reinforcing ring plate 22 in the ring plate positioning groove 210, a closer connection between the reinforcing ring plate 22 and the radially reinforcing rib 21 can be achieved, improving the stability and firmness of the connection. This can effectively reduce the looseness between structural components and ensure that the cylinder body structure does not experience displacement or damage during operation.

[0026] At least part of the outer peripheral surface of the reinforcing ring plate 22 is welded to the inner wall of the cylinder body shell 1. Welding the connection between the reinforcing ring plate 22 and the cylinder body shell 1 can effectively enhance the stability of the entire structure. And the remaining part of the outer peripheral surface of the reinforcing ring plate 22 is welded to the lower end of the cylinder body shell 1. By welding the connection between the reinforcing ring plate 22 and the cylinder body shell 1, the vibration and deformation of the structure can be effectively reduced, and the fatigue degree of the structure can be alleviated.

[0027] The reinforcing ring plate 22 and the cylinder body bottom plate 2 are parallelly distributed, forming a more stable structural layout and evenly sharing the force.

[0028] To optimize the structure and make the cylinder have a more stable and high-strength structure, the axial length of the reinforcing ring 20 is designed to be shorter than the vertical distance between the lower surface of the reinforcing ring plate 22 and the lower surface of the cylinder body bottom plate 2.

[0029] The radial reinforcing rib 21 is in the shape of a long strip, and the width of the radial reinforcing rib 21 is smaller than the axial length of the reinforcing ring 20. Specifically, the radial reinforcing rib 21 is fixedly welded to the cylinder body bottom plate 2, and when observed from the side view, the two are connected to form a "T" - shaped structure.

[0030] A through - hole 23 is provided at the center of the cylinder body bottom plate 2 for allowing the power shaft for operation to pass through the cylinder body bottom plate 2 and enter the upper chamber 11. The inner diameter of the reinforcing ring 20 is larger than the inner diameter of the through - hole 23, and the axis line of the through - hole 23 coincides with the axis line of the said reinforcing ring 20.

[0031] A fan - shaped cavity is formed between two adjacent radial reinforcing ribs 21. The structure of the fan - shaped cavity can further enhance the structural strength in design and prevent the cylinder body shell 1 from deforming and causing out - of - roundness.

[0032] Embodiment Two

[0033] The structure and principle of this embodiment are basically the same as those of Embodiment One. The different structure lies in that for the super - gravity bed cylinder of the above - mentioned Embodiment One, this super - gravity bed includes a super - gravity bed cylinder.

[0034] The super - gravity bed of this embodiment is a gas - liquid contact device and can be widely used in gas - liquid contact occasions such as absorption, rectification, chemical reaction, and nano - material preparation in industries such as chemical engineering, petrochemical engineering, biochemical engineering, pharmacy, metallurgy, and light industry.

[0035] The super - gravity field bed is characterized by its small volume and is known as the "transistor" in chemical engineering equipment. Before the present invention was made, most of the existing super - gravity field rotating beds rotated the entire rotor together, and gas and liquid counter - currently contacted inside the rotor under a centrifugal force far greater than gravity. There are many kinds of structures inside the existing rotating bed rotors, but mainly porous medium packings such as metal wire meshes and plate packings. Due to the too - short contact time of gas - liquid phases in the packing, it is not conducive to gas - liquid inter - phase mass transfer. It is difficult for the liquid to be evenly distributed, resulting in gas - liquid short - circuit or liquid channeling, which reduces the mass transfer efficiency. Since the rotor rotates with the shaft, it is very difficult for the existing rotating bed to achieve the problem of intermediate feeding in continuous rectification operation of a single rotating bed. At least two rotating beds are required for continuous rectification operation.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
