[0002] Fiberglass composite tanks, commonly known as FRP tanks, are non-metallic composite tanks made of resin and glass fiber wound by microcomputer-controlled machines. The manufacturing process of this tank is usually carried out by microcomputer-controlled machines to ensure the uniformity and strength of the tank structure.

[0003] Existing storage tank materials have certain limitations in terms of corrosion resistance, strength and lightness. Especially in situations where insulation performance is required, such as when storing flammable, explosive or corrosive chemicals, the insulation performance of the storage tank is extremely high. Although traditional fiberglass composite tanks have certain insulation and strength, they are still difficult to meet higher requirements in special environments. Summary of the invention

[0004] Based on the technical problem that existing FRP storage tank materials have certain limitations in corrosion resistance, strength and lightness, the present invention proposes an insulating high-strength fiberglass composite tank.

[0005] The present invention proposes an insulating high-strength glass fiber composite tank, comprising a glass fiber reinforced plastic tank body composed of an inner surface layer, a sub-surface layer, a structural layer, an insulating middle layer, an outer surface layer and a protective layer, wherein the inner surface layer, the sub-surface layer, the structural layer, the insulating middle layer, the outer surface layer and the protective layer are stacked from the inside to the outside, and a transport bracket is arranged at the bottom of the glass fiber reinforced plastic tank body, and a connecting mechanism is arranged between the transport bracket and the glass fiber reinforced plastic tank body.

[0006] Wherein, the connecting mechanism is used to connect the transport bracket and the protective layer together, so as to facilitate transportation.

[0007] Preferably, the material of the inner surface layer is a surface felt impregnated with vinyl ester resin, and a nano-scale insulating coating is coated on one side of the inner surface layer.

[0008] Through the above technical scheme, the vinyl ester resin and the curing agent are mixed, and the accelerator, defoaming agent or other auxiliary agents are added as needed, and then the surface felt is immersed in the prepared vinyl ester resin to ensure that the surface felt is completely soaked with the vinyl ester resin, and then laid inside the tank in multiple layers so that each layer is fully bonded to the previous layer; the nano-scale insulating coating is used to improve the insulation performance and corrosion resistance of the tank.

[0009] Preferably, the sub-surface layer is made of a mixture of chopped glass fiber and vinyl ester resin, and a coupling agent is coated on the surface of the chopped glass fiber.

[0010] Through the above technical scheme, the surface of the chopped FRP fibers is coated with a coupling agent to facilitate improving its bonding performance with the vinyl ester resin; the addition of the chopped FRP fibers increases the toughness of the FRP tank body, making it less likely to break when subjected to impact or stress, and when the FRP tank body is subjected to external force and cracks are generated, it can also prevent the cracks from further expanding.

[0011] Preferably, the structural layer is made of glass fiber roving impregnated with epoxy resin, and the structural layer is filled with insulating filler.

[0012] Through the above technical solution, the glass fiber roving is formed into a high-strength, impact-resistant tank structure through the staggered laying technology; the insulating filler added to the structural layer is used to improve the insulation performance of the FRP tank body.

[0013] Preferably, the insulating middle layer is made of polystyrene foam.

At the same time, the polyurethane rubber is convenient for reducing wear points and improving the overall wear resistance and impact resistance of the tank.

[0019] Preferably, the connection mechanism comprises self-locking universal wheels, and the self-locking universal wheels are distributed in a rectangular array at the bottom of the transport bracket.

[0020] Through the above technical solution, the rotation of the self-locking universal wheel drives the transport bracket to move, thereby facilitating the transportation of the FRP storage tank body, and at the same time preventing the transport bracket from moving when not in use.

[0021] Preferably, a buffer pad is fixedly connected to the surface of the transport bracket in contact with the outer layer, and the buffer pad and the protective layer are distributed alternately.

[0022] Through the above technical solution, the transport bracket is prevented from directly contacting the tank body, thereby protecting the tank body from wear and tear.

[0024] Through the above technical solution, the forward and reverse rotation of the output shaft of the driving motor drives the rotating shaft connected to it to rotate forward and reverse, the forward and reverse rotation of the rotating shaft drives the cam connected to it to rotate forward and reverse, the forward and reverse rotation of the cam drives the clamping column to move up and down along the inner wall of the slide groove, so that the clamping column enters the clamping groove, and at the same time, the transport bracket is connected to the tank body through the threaded connection of the bolt and the threaded hole.

[0025] The beneficial effects of the present invention are:

[0026] 1. By setting up a connecting mechanism, it is convenient to connect the tank body and the transport bracket together. The threaded connection between the bolt and the threaded hole is used to connect the transport bracket to the protective layer.

A transport bracket 2 is arranged at the bottom of the glass fiber reinforced plastic tank body 1, and a connecting mechanism is arranged between the transport bracket 2 and the glass fiber reinforced plastic tank body 1.

[0039] In order to improve the insulation performance and corrosion resistance of the tank body, the material of the inner surface layer 11 is a surface felt impregnated with vinyl ester resin, and a nano-scale insulating coating 111 is coated on one side of the inner surface layer 11. The vinyl ester resin is mixed with a curing agent, and a promoter, a defoaming agent or other additives are added as needed. Then, the surface felt is immersed in the prepared vinyl ester resin to ensure that the surface felt is completely impregnated with the vinyl ester resin, and then multiple layers are laid inside the tank body so that each layer is fully bonded to the previous layer; the nano-scale insulating coating 111 is used to improve the insulation performance and corrosion resistance of the tank body.

[0040] In order to increase the toughness of the tank body, the material of the sub-surface layer 12 is a mixture of chopped glass fiber and vinyl ester resin, and a coupling agent is coated on the surface of the chopped glass fiber. The coating of the coupling agent on the surface of the chopped glass fiber is convenient for improving its bonding performance with the vinyl ester resin; the addition of chopped glass fiber increases the toughness of the glass fiber reinforced plastic storage tank body 1, making it less likely to break when subjected to impact or stress, and when the glass fiber reinforced plastic storage tank body 1 is subjected to external force and cracks are generated, it can also prevent the cracks from further expanding.

[0041] In order to improve the strength and insulation performance of the tank body, the material of the structural layer 13 is glass fiber roving impregnated with epoxy resin, and insulating filler is filled in the structural layer 13. The glass fiber roving is formed through staggered laying technology to form a high-strength, impact-resistant tank structure; the insulating filler added to the structural layer 13 is used to improve the insulation performance of the FRP storage tank body 1.

[0042] In order to improve the insulation performance of the tank body, the insulating middle layer 14 is made of polystyrene foam. Polystyrene foam has a low thermal conductivity and is used to improve the insulation performance of the tank body.

[0043] By providing an insulating intermediate layer 14, filling the structural layer 13 with insulating fillers, and coating the inner surface layer 11 with a nano-level insulating coating 111, the low thermal conductivity of polystyrene foam is utilized to improve the insulation performance of the FRP storage tank body 1.

[0044] In order to improve the durability of the tank body, the outer layer 15 is made of a mixture of weather-resistant resin and anti-aging agent. At the same time, ultraviolet absorbers and antioxidants are coated on the surface of the outer layer 15 to extend the service life of the FRP tank body 1 in outdoor environments, improve the long-term durability of the FRP tank body 1 and its performance in harsh environments, delay the aging process of the FRP tank body 1 when exposed to light, heat, oxygen and other environmental factors, and resist the degradation effect of ultraviolet rays.

[0045] In order to improve the wear resistance of the tank body, the protective layer 16 is made of polyurethane rubber. The protective layer 16 is distributed on the surface of the outer layer 15 in a cross shape. The protective layer 16 is distributed on the surface of the tank body in a cross shape to form a mesh structure, which can effectively disperse the external impact force. At the same time, polyurethane rubber facilitates to reduce wear points and improve the overall wear resistance and impact resistance of the tank body.

[0046] By setting the sub-surface layer 12, the structural layer 13 and the protective layer 16, the toughness of the FRP tank body 1 is increased by using chopped FRP fibers, and the glass fiber roving is staggered and laid in layers to form a high-strength, impact-resistant tank structure, while polyurethane rubber is used to improve the durability of the tank body, thereby increasing the strength of the FRP tank body 1.

[0047] Among them, in order to connect the transport bracket 2 and the protective layer 16 together, so as to facilitate the transportation of the tank body, the connecting mechanism provided includes self-locking universal wheels 3, which are distributed in a rectangular array at the bottom of the transport bracket 2. The rotation of the self-locking universal wheels 3 drives the transport bracket 2 to move, thereby facilitating the transportation of the fiberglass reinforced plastic storage tank body 1. At the same time, it can also prevent the transport bracket 2 from moving when not in use.

[0048] In order to protect the tank body, a buffer pad 31 is fixedly connected to the surface where the transport bracket 2 contacts the outer layer 15 . The buffer pad 31 and the protective layer 16 are staggered to prevent the transport bracket 2 from directly contacting the tank body and protect the tank body from wear.

[0049] In order to realize the connection between the transport bracket 2 and the tank body, the inner wall of the transport bracket 2 is symmetrically installed with a rotating shaft 32 through a bearing, and the surfaces of the two rotating shafts 32 are fixedly sleeved with cams 33. The surface of the transport bracket 2 is symmetrically installed with a driving motor 34, and one end of the output shaft of the two driving motors 34 is respectively fixedly sleeved with one end of the two rotating shafts 32. The upper surface of the transport bracket 2 is symmetrically distributed with a sliding groove 35, and the inner wall of the sliding groove 35 is slidably engaged with a clamping column 36.

At the same time, threaded holes 38 are provided on the surfaces of the protective layer 16 and the transport bracket 2. Bolts 39 are threadedly connected to the inner wall of the threaded hole 38. The output shaft of the driving motor 34 drives the rotating shaft 32 connected thereto to rotate forward and reversely. The forward and reverse rotation of the rotating shaft 32 drives the cam 33 connected thereto to rotate forward and reversely. The forward and reverse rotation of the cam 33 drives the clamping column 36 to move up and down along the inner wall of the slide groove 35, so that the clamping column 36 enters the clamping groove 37. At the same time, the transport bracket 2 is connected to the tank body through the threaded connection of the bolt 39 and the threaded hole 38.

[0050] By setting up a connecting mechanism, it is convenient to connect the tank body and the transport bracket 2 together. The threaded connection between the bolt 39 and the threaded hole 38 is used to connect the transport bracket 2 to the protective layer 16. At the same time, the cam 33 is used to make the clamping column 36 enter the clamping groove 37, so as to further connect the transport bracket 2 to the protective layer 16 together, thereby facilitating the transport bracket 2 to carry the fiberglass storage tank body 1 and avoiding damage to the tank body during transportation.
