Description

Technical Field

[0001] This utility model relates to the technical field of zeolite rotor support equipment, specifically, to a non-welded support structure for a zeolite rotor. Background Technology

[0002] In zeolite rotor adsorption and concentration equipment, the support structure is the core component that ensures stable rotor rotation and bears the weight of the equipment. Traditional zeolite rotor support structures are mostly assembled using welding processes, where metal rods are welded together to form a frame system, and then rotating support components such as bearing seats are installed on the frame. However, this welded support structure has many technical drawbacks:

[0003] First, the high temperatures during welding can cause stress concentration within the metal material, easily leading to structural deformation or cracking. Especially under long-term load-bearing and vibration conditions, the risk of fatigue failure at welded joints increases significantly, severely impacting equipment lifespan and operational safety. Second, welding processes require high machining precision, making on-site welding operations difficult. Furthermore, any dimensional deviations or welding defects are difficult to disassemble and rework, resulting in low assembly efficiency. In addition, welded structures have low modularity; component replacement during later maintenance requires cutting and welding, which is complex and costly, failing to meet the needs of rapid equipment maintenance and upgrades.

[0004] Therefore, in view of the problems of stress concentration, poor assembly flexibility and maintenance difficulties of traditional welded support structures, there is an urgent need for a zeolite rotor support structure that adopts a non-welded connection method, has high structural stability and is easy to assemble and maintain. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a non-welded support structure for a zeolite rotor. All rods are quickly connected by bolts through edge mounting holes, eliminating the need for on-site welding or non-standard processing. This significantly reduces assembly difficulty and labor costs, facilitates mass production, and significantly reduces the risk of fatigue failure due to the absence of welding nodes.

[0006] A non-welded support structure for a zeolite rotor includes a support plate with a through hole. First fixing rods are fixedly mounted on the upper and lower sides of the support plate, and third fixing rods are fixedly mounted on both sides of the support plate. The first fixing rods and the support plate are bolted together, and the third fixing rods and the support plate are also bolted together. The first fixing rods are fixedly connected to the third support rods. The middle portions of the two third support rods are respectively fixedly connected to the two ends of a second fixing rod. A support member is fixedly connected to the upper middle portion of the second fixing rod. A bearing seat is provided inside the support member and fixed to the upper side of the second fixing rod.

[0007] Furthermore, the lower middle part of the second fixing rod is fixedly connected to the lower first fixing rod by a column, and there are two columns, which are respectively fixedly connected to the two ends of the symmetrical connecting rod.

[0008] Furthermore, the lower ends of the first inclined support rod are fixedly connected to the upper two ends of the support member, the upper end of the first inclined support rod is fixedly connected to the first fixed rod on the upper side, the support rod is fixedly connected to the middle part of the upper side of the support member, and the support rod is fixedly connected to the first fixed rod on the upper side.

[0009] Furthermore, the support member and the first inclined support rod are fixedly connected to a reinforcing plate.

[0010] Furthermore, the upper middle part of the first fixed rod on the lower side is fixedly connected to the second inclined support rod on both sides, and the other end of the second inclined support rod is fixedly connected to the lower middle part of the third fixed rod.

[0011] Furthermore, the first fixing rod, the second fixing rod, the third fixing rod, the first inclined support rod, the second inclined support rod, the support rod, the support member, and the column are all bent parts with side bends, and each of their edges is provided with mounting holes for mounting bolts to achieve a locking connection.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are:

[0013] The three-dimensional frame formed by the first and third fixed rods serves as the basic load-bearing skeleton. Combined with components such as columns and diagonal support rods, a multi-directional force-bearing system is constructed. In the vertical direction, the upper load is transferred to the lower frame through the columns, while in the horizontal direction, the diagonal support rods and connecting rods utilize the stability of triangles to offset the lateral force, so that the load is evenly distributed throughout the entire structure. This significantly improves the bending and overturning resistance of the support structure, and can stably bear the weight of the zeolite rotor and the dynamic load during rotation. There are no welding joints, and the risk of fatigue failure is significantly reduced.

[0014] The through-hole design on the support plate achieves multiple functions such as weight reduction, heat dissipation, and pipeline avoidance, reducing the overall structural weight; the side-bent rods, through cross-sectional shape optimization (such as "U-shaped" and "L-shaped"), have higher stiffness than the flat structure with the same amount of material, balancing lightweight and high strength.

[0015] All components are quickly bolted together via edge mounting holes, eliminating the need for on-site welding or non-standard machining. This significantly reduces assembly difficulty and labor costs, facilitating mass production. Furthermore, the modular design allows for individual disassembly and replacement of damaged parts during later maintenance, eliminating the need for complete disassembly and drastically shortening maintenance cycles while improving equipment operation and maintenance efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] A non-welded support structure for a zeolite rotor includes a support plate 12 with through holes. First fixing rods 1 are fixedly mounted on the upper and lower sides of the support plate 12, and third fixing rods 13 are mounted on both sides of the support plate 12. The first fixing rods 1 and the support plate 12 are connected by bolts, and the third fixing rods 13 and the support plate 12 are also connected by bolts. The first fixing rods 1 are fixedly connected to the third support rods 2. The middle portions of the two third support rods 2 are respectively fixedly connected to the two ends of a second fixing rod 5. A support member 10 is fixedly connected to the upper middle portion of the second fixing rod 5. A bearing seat 9 is provided inside the support member 10 and is fixed to the upper side of the second fixing rod 5.

[0022] In this embodiment, bolted connections are used instead of welding to avoid material performance degradation and structural deformation caused by high-temperature welding. A three-dimensional frame is formed by the first fixing rod 1 (vertical direction) and the third fixing rod 13 (lateral direction), providing a basic load-bearing skeleton for the overall structure. The combination of the support member 10 and the bearing seat 9 is designed to meet the rotation requirements of the zeolite rotor. The through holes on the support plate 12 can achieve weight reduction, heat dissipation, or pipeline avoidance, optimizing the lightweight structure. The bolted fastening of the first fixing rod 1, the third fixing rod 13, and the support plate 12 achieves welding-free assembly, reduces processing difficulty, facilitates disassembly and maintenance, and avoids the risk of structural cracking caused by welding stress. The rectangular (or near-rectangular) frame formed by the first fixing rod 1 and the third fixing rod 13 provides basic rigidity for the entire support structure and bears the overall weight of the zeolite rotor. The second fixing rod 5 connects to the third support rod 2 to form lateral reinforcement. The support member 10 and the built-in bearing seat 9 are directly used to install the rotating shaft of the zeolite rotor. The bearing seat 9 reduces the shaft rotation resistance through rolling friction, ensuring the smooth operation of the rotor.

[0023] The lower middle part of the second fixing rod 5 is fixedly connected to the lower first fixing rod 1 by a column 7. There are two columns 7, which are respectively fixedly connected to the two ends of the symmetrical connecting rod 8.

[0024] In this embodiment, the second fixed rod 5 is rigidly connected to the lower first fixed rod 1 by the column 7, forming a vertical force transmission path; the connecting rod 8 enhances the resistance to lateral deformation of the column 7 by symmetrical arrangement, preventing the column 7 from tilting due to single-point force. The column 7, as an intermediate connector, directly transmits the upper load (such as the weight of the wheel) borne by the second fixed rod 5 to the lower first fixed rod 1, dispersing the vertical force on the second fixed rod 5 and preventing it from bending due to excessive cantilever force. The two columns 7 are symmetrically arranged and, together with the connecting rod 8, form a stable structure with double columns and crossbar fixed cooperation, enhancing the resistance to deformation of the column 7 in the horizontal direction (such as the centrifugal force impact when the wheel rotates), and preventing the column 7 from tilting on one side.

[0025] The upper two ends of the support member 10 are respectively fixedly connected to the lower ends of the first inclined support rod 3, the upper end of the first inclined support rod 3 is fixedly connected to the first fixed rod 1 on the upper side, the upper middle part of the support member 10 is fixedly connected to the support rod 2, and the support rod 2 is fixedly connected to the first fixed rod 1 on the upper side.

[0026] In this embodiment, utilizing the principle of triangular stability, the support member 10 and the upper first fixed rod 1 are connected by the first inclined support rod 3 and the support rod 2 to form a multi-point tie structure. This disperses the radial force (such as the eccentric load when the wheel rotates) borne by the support member 10 to the upper frame, preventing the support member 10 from being overloaded at a single point. The first inclined support rod 3 is arranged at an inclination to transfer the lateral forces (such as the unbalanced force when the wheel rotates) on both sides of the support member 10 to the upper first fixed rod 1. The shear resistance of the triangular structure is used to offset the lateral deformation. The support rod 2 vertically connects the middle part of the support member 10 to the upper first fixed rod 1, assisting in bearing the vertical load of the support member 10. Together with the inclined support rod 2, it forms a "vertical and horizontal" force system, reducing the stress at the connection point between the support member 10 and the second fixed rod 5.

[0027] The support member 10 and the first inclined support rod 3 are fixedly connected to the reinforcing plate 4. Based on the principle of local strength reinforcement, the reinforcing plate 4 increases the moment of inertia of the section at the connection between the support member 10 and the first inclined support rod 3, thereby improving the bending and shear resistance of this area and avoiding connection failure due to stress concentration. The connection between the support member 10 and the first inclined support rod 3 is a stress concentration area (where oblique tension and vertical pressure intersect). The reinforcing plate 4 increases the material thickness and rigidity of this area, disperses the stress peak, and prevents the connection from cracking due to fatigue.

[0028] As a further preferred option, the reinforcing plate 4 can be made of some existing insulation materials, and the reinforcing plate 4 also has a certain insulation effect.

[0029] The upper middle part of the first fixed rod 1 on the lower side is fixedly connected to the second inclined support rod 6 on both sides, and the other end of the second inclined support rod 6 is fixedly connected to the lower middle part of the third fixed rod 13. The second inclined support rod 6 forms a triangular connection between the first fixed rod 1 on the lower side and the third fixed rod 13, which enhances the resistance to lateral deformation of the lower frame and improves the overall structure's anti-overturning stability. The third fixed rod 13, as a longitudinal force-bearing member on both sides, is prone to lateral deformation inward or outward due to the upper load. The second inclined support rod 6 connects it to the first fixed rod 1 on the lower side by inclined connection to form a triangular stable structure.

[0030] The first fixing rod 1, the second fixing rod 5, the third fixing rod 13, the first inclined support rod 3, the second inclined support rod 6, the support rod 2, the support member 10, and the column 7 are all bent parts with side bends, and each of their edges is provided with mounting holes 11 for mounting bolts to achieve a locking connection.

[0031] The stiffness of the members is improved by bending, and the unified installation hole 11 design enables fully bolted modular assembly, replacing traditional welding and non-standard processing, reducing costs and improving interchangeability. The side-bent members have higher cross-sectional moment of inertia and bending resistance than flat structures with the same amount of material, thanks to the optimized cross-sectional shape (such as "U" and "L"). This improves the load-bearing limit of individual members. The unified opening of the edge installation holes 11 allows all members to be quickly connected by bolts without on-site welding or custom processing, reducing assembly difficulty and facilitating mass production and later maintenance (such as component replacement).

[0032] The assembly of this utility model includes the following steps: 1. Basic frame assembly: First, according to the drawings, install holes 11 are made on each component. After the holes are made, the components are assembled. The support plate 12 is placed horizontally. The first fixing rods 1 on the upper and lower sides are locked to the upper and lower edges of the support plate 12 by bolts, ensuring that the first fixing rods 1 are perpendicular to the support plate 12 and symmetrical in position. Similarly, the third fixing rods 13 on both sides are locked to the two sides of the support plate 12 by bolts, so that the first fixing rods 1 and the third fixing rods 13 form a rectangular (or rectangular) three-dimensional frame. The bolts need to be tightened evenly to ensure the levelness of the frame.

[0033] 2. Installation of lateral reinforcement and rotation support components: Connect the two ends of the two third support rods 2 to the third fixed rods 13 on both sides with bolts respectively, and then fix the two ends of the second fixed rod 5 to the middle of the third support rod 2 with bolts to form a lateral reinforcement structure; install the support member 10 with bolts on the upper middle of the second fixed rod 5, embed the bearing seat 9 into the support member 10 and fix it with bolts to ensure that the axis of the bearing seat 9 is concentric with the rotation axis of the zeolite wheel;

[0034] 3. Vertical and Lateral Support Reinforcement: At the lower middle of the second fixed rod 5, the upper ends of the two columns 7 are connected to the second fixed rod 5 by bolts, and the lower ends are bolted to the lower first fixed rod 1; the two ends of the connecting rod 8 are respectively bolted to the two columns 7; at the upper ends of the support member 10, the lower ends of the first inclined support rod 3 are connected by bolts, and the upper ends are bolted to the upper first fixed rod 1; at the upper middle of the support member 10, the lower ends of the support rod 2 are connected by bolts, and the upper ends are bolted to the upper first fixed rod 1, ensuring that the inclined support rod 2 and the support rod 2 are subjected to uniform force; at the connection between the support member 10 and the first inclined support rod 3, the reinforcing plate 4 is bolted to enhance the local strength.

[0035] 4. Bottom frame stabilization and reinforcement: The lower ends of the second inclined support rods 6 are respectively connected to the upper middle part of the first fixed rod 1 on both sides by bolts, and the other end is fixed to the lower middle part of the third fixed rod 13 by bolts, forming a triangular tie structure to improve the lateral deformation resistance of the lower frame.

[0036] Equipment installation and operation: After the overall structure is assembled and all bolts are checked and tightened, install the assembled structure in a suitable position, ensuring that the opening of the support plate 12 and the installation direction of the zeolite rotor's rotation shaft are coaxial. Install the zeolite rotor's rotation shaft into the bearing seat 9, ensuring that the shaft and bearing seat 9 fit well. Start the equipment, and the rotor will rotate smoothly through the rolling friction of the bearing seat 9. The support structure distributes the load through a multi-directional force system, ensuring long-term stable operation of the equipment.

[0037] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
