Description

Technical Field

[0001] The utility model relates to the technical field of containers, in particular to a storage tank. Background Art

[0002] FRP storage tanks are a new type of composite material made of glass fiber as a reinforcement and resin as a binder, manufactured through controlled winding. They are widely used in the chemical, food, and environmental protection industries, offering advantages such as corrosion resistance, high strength, and lightweight. However, traditional FRP storage tanks typically have a flat bottom design, which can lead to incomplete material discharge in actual use.

[0003] In order to eliminate the above disadvantages, the relevant technology proposes a tank body with an inclined bottom, and a inclined bottom structure is arranged underneath it. The inclined bottom structure is used to support the tank body and improve the structural stability of the tank body when carrying materials. The inclined surface of the inclined bottom structure can also facilitate the complete discharge of materials in the tank body when using the container.

[0004] However, the fixation between the tank body and the inclined bottom structure in the container needs to be achieved by later setting a reinforcement at the connection point. The reinforcement is circumferentially arranged on the inclined surface of the inclined bottom structure and fixedly connected to the inner wall of the tank body. The presence of the reinforcement will affect the inclination angle and flatness of the inclined surface of the inclined bottom structure, thereby causing material to accumulate on the inclined bottom structure. Utility Model Content

[0027] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connect" and "fixed" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical or electrical connections, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0029] In the description of the present utility model, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figure 1-Figure 2As shown, the present invention provides a storage tank, including a support structure 1, a tank bottom structure 2 and a tank body structure 3, wherein the tank bottom structure 2 includes an integrally formed cylindrical portion 21 and an inclined bottom portion 22, the inclined bottom portion 22 being inclined relative to the horizontal plane, and the processing of the tank bottom structure 2 can be processed by a mold forming process. The inclined bottom produced by the traditional manual laying method is usually uneven, while the use of a mold forming process can ensure that the produced inclined bottom portion 22 is smooth and flat, and there is no need to use additional connectors to connect and fix the cylindrical portion 21 and the inclined bottom portion 22. The degree of inclination and the smoothness of the surface of the inclined bottom portion 22 will not be affected by the connection between the two. When storing materials in the storage tank, it is not easy to accumulate at the connection between the inclined bottom portion 22 and the cylindrical portion 21. The production of the tank bottom structure 2 by mold prefabrication and standardized processes can also shorten the production cycle and simplify the production process. The tank bottom structure 2 can be prefabricated in advance, which is suitable for mass production of storage tanks.

[0032] The inclination angle of the inclined bottom 22 can be between 3 degrees and 10 degrees. Within this inclination angle range, the material can be evenly distributed on the inclined bottom 22 when the storage tank carries the material, avoiding the uneven distribution of the material on the inclined bottom 22 when the inclination angle is too small, which in turn causes different bearing pressures on different parts of the inclined bottom 22. It can also avoid the vertical component force on the inclined bottom 22 being too large when the storage tank carries the material when the inclination angle is too large. Selecting an inclined bottom 22 with a reasonable inclination angle can improve its bearing capacity, avoid damage to the inclined bottom 22 during the bearing process, and effectively extend the service life of the tank bottom structure 2.

[0033] In order to prevent the inclined bottom 22 from shaking or deflecting when carrying heavy objects, a support structure 1 is provided below the tank bottom structure 2. The support structure 1 can effectively support the tank bottom structure 2 when the tank is storing materials, thereby improving the load-bearing capacity of the inclined bottom 22. The support structure 1 can include a support cylinder 11, the upper barrel opening of the support cylinder 11 is tilted upward, the tilt angle of the upper barrel opening is consistent with the tilt angle of the inclined bottom 22, the lower barrel opening is arranged in a horizontal direction, and the top of the support cylinder 11 is connected to the bottom surface of the inclined bottom 22. The barrel opening diameter of the lower barrel opening of the support cylinder 11 is consistent with the barrel opening diameter of the barrel portion 21. Combined with the setting of its tilted barrel opening, it can ensure that when the support cylinder 11 is connected to the tank bottom structure 2, the various components of the two are tightly fitted.

[0034] like Figure 1 and Figure 2As shown, in order to improve the bearing capacity of the supporting structure 1, a plurality of first support members 12 can be arranged in the supporting cylinder 11. The plurality of first support members 12 are parallel to each other and spaced apart along a first direction. The first direction is a direction parallel to the axis of the supporting cylinder 11. No further details will be given. The plurality of first support members 12 are all connected to the inclined bottom 22, and their existence can effectively share the bearing pressure borne by the inclined bottom 22. The first support member 12 can be made of a material with high bearing strength, such as fiberglass or carbon fiber composite materials, and no excessive restrictions are made here.

[0035] In one embodiment, a plurality of second support members 13 are further provided in the support cylinder 11. The plurality of second support members 13 are parallel to each other and are arranged at intervals along a second direction that is at an angle to the first direction. The second direction is preferably perpendicular to the first direction, that is, perpendicular to the direction of the axis of the support cylinder 11. The first support member 12 and the second support member 13 are arranged along different directions to enhance the overall structural stability of the support cylinder 11 and avoid deformation of the support cylinder 11 in the process of supporting the inclined bottom 22. The second support member 13 can be made of a material with high bearing strength, such as fiberglass or carbon fiber composite material, and no further restrictions are imposed here.

[0036] Multiple first support members 12 and multiple second support members 13 can be connected to form multiple grid spaces 14. A filling structure 141 is provided in the grid space 14. The filling structure 141 can fill the grid space 14 to prevent the first support members 12 and the second support members 13 from deforming during the load-bearing process, and can also improve the overall structural strength of the support structure 1 and enhance its support effect on the tank bottom structure 2. The filling structure 141 may include a ceramsite filling layer and a resin filling layer, which are alternately arranged in the grille space 14. During the actual filling process, the resin filling layer may be first laid at the bottom of the grille space 14, and then the ceramsite filling layer may be arranged on the resin filling layer. After the ceramsite filling layer is filled, the resin filling layer may be added on its upper part. The resin filling layer may be bonded to the surfaces of the first support member 12 and the second support member 13, so that the ceramsite filling layer in the middle position can be stably filled in the grille space 14. The above filling process may enhance the structural stability of the filling structure 141 when it is subjected to external pressure, and prevent the filling structure 141 from loosening or shifting in the process of supporting the tank bottom structure 2. The support structure 1 can also include a support portion 15, which is sealed and connected to the lower cylinder mouth of the support cylinder 11. The support portion 15 can prevent the filling structure 141 from separating from the above-mentioned grid space 14, enhance the structural integrity of the filling structure 141 and the first support member 12, the second support member 13 and the support cylinder 11, and can also enhance the supporting effect of the support cylinder 11.

[0037] The height of the tank bottom structure 2 produced by the mold during actual production is limited, and the inner cylinder 31 needs to be connected to the upper part of the tank bottom structure 2, that is, the inner cylinder 31 is connected to the top of the cylinder part 21 to increase the storage tank's capacity. Taking into account the height limit of the manufacturing plant, the cylinder part 21 and the inner cylinder 31 can use a horizontal connection technology, that is, after the tank bottom structure 2 and the inner cylinder 31 are completed, they are placed horizontally, and when the cylinder part 21 and the inner cylinder 31 are opposite to each other, the adhesive material is applied on their end faces, and then the two are continued to be moved until the cylinder part 21 and the inner cylinder 31 are connected under the action of the adhesive material. According to the curing time requirements of the adhesive material, the two are left still until the cylinder part 21 and the inner cylinder 31 are completely fixed. During curing, external force should be avoided on the connection between the two to avoid affecting the bonding effect. The adhesive material can be a resin.

[0038] The barrel portion 21 formed by a mold can have a longitudinal cross-section in the form of a right-angled trapezoid, that is, the barrel opening on the side where the barrel portion 21 is connected to the inner barrel 31 is arranged in the horizontal direction. Accordingly, the inner barrel 31 connected thereto can be processed into a cylindrical structure that is symmetrical up and down, reducing the processing accuracy requirements for the inner barrel 31, and avoiding the situation in the prior art where the lower barrel opening of the inner barrel 31 needs to be processed into an inclined barrel opening. The connection between the tank bottom structure 2 and the tank body structure 3 is achieved by connecting the end faces of the two horizontal barrel openings. The connection process between the tank bottom structure 2 and the tank body structure 3 does not require consideration of angle adjustment, and the connection process is simple and easy to implement.

[0039] The inner cylinder 31, the cylinder portion 21 and the support structure 1 can be connected to each other to form a unified whole. The three can be connected and fixed by a hand lay-up molding process, that is, an adhesive material is applied manually on the contact surfaces between the inner cylinder 31, the cylinder portion 21 and the support structure 1 that need to be connected and fixed. The adhesive material can be a resin, and the inner cylinder 31, the cylinder portion 21 and the support structure 1 can be connected to form a whole with the help of the adhesive material. However, in order to avoid the separation of the various structures when the storage tank is carrying materials, the outer cylinder 32 can be wrapped around the outside of the three after the connection is completed, that is, the inner wall surface of the outer cylinder 32 is connected to the outer wall surface of the support structure 1, the inner cylinder 31 and the cylinder part 21. The outer cylinder 32 can be made by a winding machine so that the outer cylinder 32 can tightly wrap the inner cylinder 31, the cylinder part 21 and the support structure 1, thereby improving the connection strength between the three, thereby improving the overall structural strength and load-bearing stability of the storage tank, and improving the pressure resistance and corrosion resistance of the storage tank. The material of the outer cylinder 32 can be fiberglass or other materials with excellent pressure resistance, which are not limited here.

[0040] In order to avoid accumulation of materials at the connection between the barrel portion 21 and the inner barrel 31, the inner wall surface of the barrel portion 21 can be set flush with the inner wall surface of the inner barrel 31 when the two are connected. In a preferred embodiment, the wall thickness of the inner barrel 31 is the same as the wall thickness of the barrel portion 21. The same wall thickness of the two can reduce the requirements for the winding process of the outer barrel 32. It is only necessary to evenly wrap the outer barrel 32 around the outside of the three to achieve its connection and fixing effect on the inner barrel 31, the barrel portion 21 and the support structure 1. It can also effectively improve the stability of the connection between the tank bottom structure 2 and the tank structure 3. It can also avoid the need for additional grinding or other treatment of parts of different thicknesses when the wall thicknesses of the two are different. Setting the same wall thickness for the inner barrel 31 and the barrel portion 21 can reduce material waste and improve the utilization rate of manufacturing materials.

[0041] In a specific embodiment, the production and manufacturing process of the storage tank of the present invention can be carried out in sequence according to the following steps. First, it is necessary to design and manufacture a mold for the tank bottom structure 2 according to the size of the storage tank and the inclination angle requirements of the inclined bottom 22, ensuring that the inclination angle of the inclined bottom 22 is between 3 degrees and 10 degrees, and then polish the surface of the mold and apply a release agent on the mold surface to ensure that the surface of the mold is smooth and easy to demold; after the mold is made, it is necessary to use glass fiber cloth and resin material to lay them layer by layer on the mold to ensure that each layer of glass fiber cloth is evenly impregnated with resin. After laying, it is cured and checked whether the tank bottom structure 2, especially the inclined bottom 22, is smooth. After confirming that it is smooth, make a support cylinder 11 with the same inner diameter as the cylinder part 21. The inclination angle of the cylinder mouth on the side where the support cylinder 11 and the cylinder part 21 are connected is consistent with the inclination angle of the inclined bottom 22. After the production is completed, connect the support cylinder 11 to the cylinder part 21, and then install multiple cross-arranged first support members 12 and second support members 13 inside the support cylinder 11 to ensure that the support structure 1 under the tank bottom structure 2 has sufficient load-bearing capacity to avoid deformation of the inclined bottom 22 due to long-term material bearing or external force.

[0042] To prevent deformation of the first and second support members 12, 13 during load-bearing, the gridded space 14 formed between the first and second support members 12, 13 is filled with ceramsite material. A resin filling layer is placed between adjacent ceramsite filling layers. After filling, the inclined bottom 22 is leveled using a yarn spraying process to ensure a smooth surface on the side where the inclined bottom 22 contacts the support cylinder 11. After assembling the first and second support members 12, 13, and filling structure 141, the connecting support portion 15 can be sealed at the bottom of the support cylinder 11 to enhance the structural integrity of the various components of the support structure 1. After the tank bottom structure 2 and support structure 1 are connected, the inner cylinder 31 is connected above the cylinder portion 21 to increase the storage tank's capacity. Due to the height restrictions of the factory building, the connection between the two is achieved through horizontal docking to ensure smooth installation of the inner cylinder 31. After the inner cylinder 31, tank bottom structure 2, and support structure 1 are successfully connected, the outer cylinder 32 is wrapped around the outer edges of the three to enhance the tank's structural stability. After the winding is completed, the storage tank is placed in a constant temperature environment for curing. After the curing is completed, the entire storage tank is completed.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
