Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a fiber-wound fiberglass equipment with a stiffness-enhancing structure. Background Technology

[0002] Fiber-wound fiberglass tanks are glass fiber reinforced plastic (FRP) containers manufactured using a fiber winding molding process. They are widely used in chemical, environmental protection, water treatment, and food industries, serving functions such as storage, reaction, and transportation. Their core advantages are high strength, corrosion resistance, and lightweight, and these performance characteristics directly depend on the synergistic effect of the fiber and resin, as well as the design of the winding process.

[0003] In the conventional winding process of fiber-wound FRP tanks in the existing technology, the fiber layers at both ends are usually thicker to ensure the connection strength between the end caps and the cylinder. However, in the middle section, in order to pursue lightweighting or process simplification, the fiber layers may be thinner, and the winding is mainly circumferential to resist internal pressure, with insufficient axial fiber ratio. Insufficient axial fiber will lead to weak bending and axial deformation resistance in the middle section, resulting in insufficient stiffness. With the increase of usage time and frequency, insufficient stiffness may lead to bulging, bending and other deformations, which may cause leakage or even bursting. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fiber-wound fiberglass equipment with a stiffness-enhancing structure to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: A fiber-wound fiberglass equipment with a stiffness-enhancing structure includes a tank body. A first support ring and a second support ring are provided on the outer side of the middle part of the tank body. The first support ring is located above the second support ring. A plurality of reinforcing plates are provided at equal intervals between the first support ring and the second support ring around the circumference of the tank body. A corrugated plate is provided between every two reinforcing plates.

[0006] Preferably, the outer diameter of the second support ring is greater than the outer diameter of the first support ring, and the thickness of the reinforcing plate is equal to the thickness of the first support ring.

[0007] Preferably, the reinforcing plate includes an outer panel layer, a honeycomb core layer, and an inner adhesive layer, wherein the inner adhesive layer is bonded to the outer side of the tank body.

[0008] Preferably, a carbon fiber reinforcing rod is embedded inside the honeycomb core layer.

[0009] Preferably, an inclined support beam is provided between the side surface of the outer panel layer and the upper end surface of the second support ring.

[0010] This utility model has the following beneficial effects: 1. This fiber-wound FRP equipment with a rigidity-enhanced structure uses a first and second support ring as the basic support structure, providing an installation carrier for the reinforcing plates and corrugated plates. The reinforcing plates are evenly distributed along the circumference and directly bear the bending and axial deformation forces in the middle of the tank. The corrugated plates are located between the reinforcing plates. The corrugated structure transforms the planar stress into three-dimensional bending stiffness and disperses the radial stress of the tank through its own structure. Together with the reinforcing plates, it forms a rigid reinforcing band around the middle of the tank, which makes up for the defects of thin fiber layers and insufficient axial stiffness in the middle of the tank. It solves the problem of insufficient stiffness in the middle of existing equipment, significantly improves the bending and axial deformation resistance of the middle of the tank, reduces bulging and bending deformation caused by long-term use, and reduces the risk of leakage or bursting.

[0011] 2. The reinforcing plate consists of an outer panel layer, a honeycomb core layer, and an inner adhesive layer. The inner adhesive layer is bonded to the outer side of the tank body, ensuring a firm connection between the reinforcing plate and the tank body and guaranteeing that the reinforcing plate is stressed synchronously with the tank. The honeycomb core layer utilizes the mechanical properties of the honeycomb structure, namely stress dispersion, light weight, and high strength, providing high-strength support while reducing weight. The outer panel layer, as the outer structure, protects the honeycomb core layer and transmits external stress, enhancing the rigidity of the tank while maintaining the core advantage of lightweight fiberglass equipment.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0015] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below. Example

[0016] A fiber-wound fiberglass equipment with a stiffness-enhancing structure includes a tank body 1. A first support ring 2 and a second support ring 3 are provided on the outer side of the middle part of the tank body 1. The first support ring 2 is located above the second support ring 3. A plurality of reinforcing plates 4 are provided at equal intervals around the circumference of the tank body 1 between the first support ring 2 and the second support ring 3. A corrugated plate 5 is provided between every two reinforcing plates 4.

[0017] The first support ring 2 and the second support ring 3 serve as the basic support structure, providing an installation carrier for the reinforcing plate 4 and the corrugated plate 5. The reinforcing plate 4 is evenly distributed along the circumference and directly bears the bending and axial deformation force in the middle of the tank. The corrugated plate 5 is located between the reinforcing plates 4. The corrugated structure transforms the planar stress into three-dimensional bending stiffness and disperses the radial stress of the tank through its own structure. Together with the reinforcing plate 4, it forms a rigid reinforcing band around the middle of the tank, which makes up for the defects of thin fiber layers and insufficient axial stiffness in the middle of the tank. It solves the problem of insufficient stiffness in the middle of the existing equipment, significantly improves the bending and axial deformation resistance of the middle of the tank, reduces bulging and bending deformation caused by long-term use, and reduces the risk of leakage or bursting.

[0018] In this embodiment, the outer diameter of the second support ring 3 is greater than that of the first support ring 2, the thickness of the reinforcing plate 4 is equal to that of the first support ring 2, and the outer diameter of the second support ring 3 is larger, which can expand the bottom support area and enhance the stability of the overall structure. The thickness of the reinforcing plate 4 is consistent with that of the first support ring 2, which ensures that the force at the connection between the reinforcing plate 4 and the support ring is uniform and avoids stress concentration caused by thickness difference.

[0019] In this embodiment, the reinforcing plate 4 includes an outer panel layer 41, a honeycomb core layer 42, and an inner adhesive layer 43. The inner adhesive layer 43 is attached to the outer side of the tank body 1, and the inner adhesive layer 43 realizes a firm connection between the reinforcing plate 4 and the tank body 1, ensuring that the reinforcing plate 4 is subjected to force synchronously with the tank. The honeycomb core layer 42 utilizes the mechanical properties of the honeycomb structure, namely, stress dispersion, light weight, and high strength, to provide high-strength support while reducing weight. The outer panel layer 41, as the outer layer structure, protects the honeycomb core layer 42 and transmits external stress, thereby enhancing the rigidity of the tank while maintaining the core advantage of lightweight fiberglass equipment.

[0020] In this embodiment, a carbon fiber reinforcing rod 44 is embedded inside the honeycomb core layer 42. The carbon fiber material has the characteristics of high strength, high modulus and lightweight. After being embedded in the honeycomb core layer 42, it can form a composite reinforcement system with the honeycomb structure. That is, the honeycomb core layer 42 disperses stress, and the carbon fiber reinforcing rod 44 bears the main tensile and bending forces, which synergistically improves the overall mechanical properties of the reinforcing plate 4, significantly improves the deformation resistance and structural strength of the reinforcing plate 4, enables it to withstand greater internal pressure or external load, and extends the service life of the equipment.

[0021] In this embodiment, an inclined support beam 6 is provided between the side of the outer panel layer 41 and the upper end face of the second support ring 3. The inclined support beam 6 forms a triangular stable structure. Due to the geometric stability characteristics of the triangle, the radial and axial forces borne by the outer panel layer 41 are transferred to the second support ring 3, dispersing local stress, improving the connection strength between the reinforcing plate 4 and the second support ring 3, avoiding damage to the connection part between the reinforcing plate 4 and the second support ring 3 due to force concentration, improving the stability and load-bearing capacity of the overall structure, and further ensuring the rigidity of the middle part of the tank.

[0022] The working principle of this utility model is as follows: This fiber-wound fiberglass equipment with a rigidity-enhancing structure has a first support ring 2 and a second support ring 3 located on the outer side of the middle of the tank body 1. The first support ring 2 is positioned above the second support ring 3. A plurality of reinforcing plates 4 are equidistantly arranged between the first and second support rings around the circumference of the tank body 1. A corrugated plate 5 is positioned between every two reinforcing plates 4. The first and second support rings 2 and 3 serve as the basic support structure, providing an installation carrier for the reinforcing plates 4 and corrugated plates 5. The reinforcing plates 4 are evenly distributed along the circumference, directly bearing the bending and axial deformation forces in the middle of the tank. The corrugated plates 5 are located between the reinforcing plates 4. The corrugated structure transforms planar stress into three-dimensional bending stiffness, dispersing the radial stress of the tank through its own structure. Together with the reinforcing plates 4, they form a rigid reinforcing band surrounding the middle of the tank. The reinforcing plates 4 enclose… The structure includes an outer panel layer 41, a honeycomb core layer 42, and an inner adhesive layer 43. The inner adhesive layer 43 is bonded to the outer side of the tank body 1, ensuring a firm connection between the reinforcing plate 4 and the tank body 1, and ensuring that the reinforcing plate 4 is stressed synchronously with the tank. The honeycomb core layer 42 utilizes the mechanical properties of the honeycomb structure, namely, stress dispersion, light weight, and high strength, providing high-strength support while reducing weight. The outer panel layer 41, as the outer layer structure, protects the honeycomb core layer 42 and transmits external stress, enhancing the rigidity of the tank while maintaining the core advantage of lightweight fiberglass equipment. This structure can compensate for the defects of thin fiber layers and insufficient axial stiffness in the middle of the tank, solve the problem of insufficient rigidity in the middle of existing equipment, significantly improve the bending and axial deformation resistance of the middle of the tank, reduce bulging, bending and other deformations caused by long-term use, and reduce the risk of leakage or bursting.

[0023] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.

Therefore, the protection scope of this utility model patent should be determined by the appended claims.
