Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage tank technology, and in particular to an acrylic storage tank with a heat-insulating structure. Background Technology
[0002] Acrylic acid is an important organic chemical raw material with active chemical properties and requires high temperature stability during storage. If the ambient temperature is too low, the viscosity of acrylic acid will increase, affecting subsequent transportation and use. If the temperature fluctuates too much, it may trigger local polymerization reaction and damage the quality of the raw material.
[0003] Most existing acrylic storage tanks adopt a single-layer metal tank structure. To achieve insulation, they are usually simply wrapped with insulation materials such as rock wool and glass wool on the outside of the tank. This insulation method results in poor adhesion between the insulation layer and the outer wall of the tank, which easily forms air gaps. This causes heat to be quickly dissipated through air convection, resulting in low insulation efficiency. In addition, the insulation layer lacks an effective protective structure and is easily damaged by the external environment during long-term use. This not only shortens the service life of the insulation layer, but may also cause local temperature runaway in the tank due to insulation layer damage, increasing the risk of acrylic storage. Furthermore, some storage tanks do not have targeted insulation structures designed for the top and bottom of the tank. These areas are prone to becoming weak points for heat loss, further reducing the overall insulation effect. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing acrylic storage tanks mostly adopt a single-layer metal tank structure. To achieve insulation, they are usually simply wrapped with insulation materials such as rock wool and glass wool on the outside of the tank. This insulation method results in poor adhesion between the insulation layer and the outer wall of the tank, easily forming air gaps. This leads to rapid heat loss through air convection, resulting in low insulation efficiency. Furthermore, the insulation layer lacks an effective protective structure and is easily damaged by the external environment during long-term use. This not only shortens the service life of the insulation layer but may also cause local temperature runaway in the tank due to insulation layer damage, increasing the risk of acrylic storage. In addition, some storage tanks do not have targeted insulation structures designed for the top and bottom of the tank. These areas are prone to becoming weak points for heat loss, further reducing the overall insulation effect.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an acrylic storage tank with a heat-insulating structure, including a tank body, an inner heat-insulating component, an outer protective component, a tank cover, and a support base. The tank body is a hollow tank with an open top. Flanges are fixedly installed at the opening of the tank body and on the outer surface of the tank cover. The tank cover and the tank body are detachably connected by bolts and nuts inserted into the flanges. The inner heat-insulating component is disposed on the outer surface of the tank body, the outer surface of the tank cover, and the inner bottom of the tank body. The outer protective component is sleeved on the outside of the inner heat-insulating component and forms a sealed heat-insulating cavity with the outer surface of the tank body. The bottom outer surface of the tank body is fixedly installed on the inner wall of the support base.
[0006] The aforementioned components achieve the following effects: the hollow tank structure with an opening at the top of the tank body, combined with the tank cover and the detachable connection of bolts, nuts and flanges, not only meets the storage requirements of acrylic acid, but also facilitates the opening and closing of the tank, making it convenient for internal maintenance or material loading and unloading. The inner insulation components can insulate the tank from multiple directions, and the sealed insulation cavity formed between the outer protective components and the tank body further enhances the insulation effect. The support base provides a stable installation foundation for the entire tank. The overall structural design is reasonable, improving the insulation performance and structural stability of the tank.
[0007] Preferably, the inner insulation component includes several sidewall glass wool, top cover glass wool, and bottom wall glass wool. The several sidewall glass wools are fixedly attached to the outer surface of the tank body by a high-temperature resistant adhesive. The top cover glass wool is fixedly attached to the outer surface of the tank cover by a high-temperature resistant adhesive. The bottom wall glass wool is welded and fixedly installed on the bottom of the inner wall of the tank body.
[0008] The effects achieved by the above components are as follows: by setting up glass wool on the side walls, top cover, and bottom walls in a multi-part and multi-method installation and fixing manner, the glass wool is ensured to fit tightly with each part of the storage tank, reducing air gaps and improving insulation efficiency. At the same time, the fixing method of high-temperature resistant adhesive and welding ensures the stability of the glass wool during use, making it less likely to fall off and extending the service life of the insulation components.
[0009] Preferably, a number of reinforcing ribs are fixedly installed on the side of the sidewall glass wool away from the tank body. The length of the reinforcing ribs is the same as the height of the sidewall glass wool, and the reinforcing ribs are integrally formed with the sidewall glass wool.
[0010] The effect achieved by the above components is that the reinforcing ribs can effectively enhance the overall structural strength of the sidewall glass wool, prevent the sidewall glass wool from deforming or being damaged under its own weight or external pressure, ensure the structural integrity of the sidewall glass wool, and thus maintain its good thermal insulation performance.
[0011] Preferably, the outer protective assembly includes a protective shell and a sealing strip. The protective shell is fitted onto the outer surface of the tank body and several sidewall glass wool. The top of the protective shell abuts against one side of the flange fixed on the tank body, and the bottom of the protective shell is fixedly connected to one side of the support base. One side of the sealing strip is fixedly installed on one side of the protective shell, and the other side abuts against one side of the flange fixed on the tank body.
[0012] The above-mentioned components achieve the following effects: the protective shell effectively protects the glass wool on the inner side wall, preventing it from being corroded by the external environment; the sealing strip enhances the sealing between the protective shell and the flange, ensuring the airtightness of the insulation cavity and further improving the insulation effect.
[0013] Preferably, a plurality of support protrusions are fixedly installed on the inner wall of the protective shell. One side of the support protrusion abuts against the outer surface of the glass wool on the side wall and is inserted between two adjacent reinforcing ribs. The support protrusions are integrally formed with the protective shell.
[0014] The aforementioned components achieve the following effects: the support protrusions can effectively support the side wall glass wool, preventing the protective shell from excessively compressing the side wall glass wool during installation or use. At the same time, the design of inserting between adjacent reinforcing ribs can limit the relative displacement between the protective shell and the side wall glass wool, ensuring the stability of the structure and also helping to maintain the structure of the insulation cavity.
[0015] Preferably, a hollow heat-insulating cavity is provided between the bottom of the inner wall of the support base and the tank body, and several support legs are fixedly installed at the bottom of the support base.
[0016] The effects achieved by the above components are as follows: the hollow insulation cavity can reduce the heat exchange between the bottom of the storage tank and the outside world, and enhance the insulation effect of the bottom of the storage tank; the several support legs provide stable support for the entire storage tank, raise the storage tank, avoid the bottom of the storage tank from directly contacting the ground, and reduce the influence of the ground environment on the temperature of the storage tank.
[0017] Preferably, the insulation cavity between the support base and the tank body is filled with insulation cotton.
[0018] The effect achieved by the above components is that the insulation cotton can further fill the internal space of the insulation cavity, reduce the air convection inside the insulation cavity, enhance the insulation performance of the insulation cavity, thereby improving the overall insulation effect of the bottom of the storage tank and making the insulation of various parts of the storage tank more uniform and reliable.
[0019] Preferably, a sealing gasket is provided in the connection gap between the two flanges, and lifting lugs are symmetrically fixedly installed on the top of the can lid, with one end of the lifting lugs penetrating and installed on one side of the glass wool of the top cover.
[0020] The effects achieved by the above components are as follows: the sealing gasket enhances the sealing between the tank cover and the tank body, preventing the evaporation of acrylic acid inside the tank or the entry of outside air into the tank, thus ensuring the sealing performance of the tank; the lifting lugs facilitate the lifting operation of the tank cover, making it easier to install and remove the tank cover, and improving the convenience of using the tank.
[0021] The beneficial effects of this utility model are:
[0022] The internal insulation component structure of this storage tank can effectively solve the problems of incomplete insulation, easy detachment and poor stability in the existing technology. It includes side wall glass wool, top cover glass wool and bottom wall glass wool, which form a full-range coverage from the outer surface of the storage tank body, the outer surface of the tank cover and the bottom of the inner wall of the storage tank body, respectively, to avoid local heat loss.
[0023] The outer protective component structure excels in the synergy of protection and insulation. The protective shell is fitted over the inner insulation component, effectively isolating the internal components from external impacts and corrosion, protecting the integrity of the inner insulation component. Furthermore, the support protrusions inserted between the reinforcing ribs not only provide support and positioning for the protective shell but also prevent uneven stress on the side wall glass wool, achieving multiple guarantees of protection, sealing, and insulation, and extending the overall service life of the storage tank.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0034] Figures 1-6 The acrylic storage tank shown includes a tank body 2, an inner insulation component 3, an outer protective component 4, a tank cover 5, and a support base 1. The tank body 2 is a hollow tank with an open top. Flanges 6 are fixedly installed at the opening of the tank body 2 and on the outer surface of the tank cover 5. The tank cover 5 is detachably connected to the tank body 2 by means of bolts and nuts inserted into the flanges 6. The inner insulation component 3 is disposed on the outer surface of the tank body 2, the outer surface of the tank cover 5, and the inner bottom of the tank body 2. The outer protective component 4 is sleeved on the outside of the inner insulation component 3 and forms a sealed insulation cavity with the outer surface of the tank body 2. The bottom outer surface of the tank body 2 is fixedly installed on the inner wall of the support base 1. The hollow tank structure with an opening at the top of the tank body 2, together with the tank cover 5, is detachably connected to the flange 6 via bolts, nuts, and bolts. This not only meets the storage requirements of acrylic acid but also facilitates the opening and closing of the tank, making it convenient for internal maintenance or material loading and unloading. The inner insulation component 3 can insulate the tank from multiple directions, and the sealed insulation cavity formed between the outer protective component 4 and the tank body 2 further enhances the insulation effect. The support base 1 provides a stable installation foundation for the entire tank. The overall structural design is reasonable, improving the insulation performance and structural stability of the tank.
[0035] Figures 1-6The inner insulation component 3 shown includes several sidewall glass wool 31, top cover glass wool 33, and bottom wall glass wool 32. The sidewall glass wool 31 is fixedly attached to the outer surface of the tank body 2 using a high-temperature resistant adhesive. The top cover glass wool 33 is fixedly attached to the outer surface of the tank cover 5 using a high-temperature resistant adhesive. The bottom wall glass wool 32 is welded and fixed to the bottom of the inner wall of the tank body 2. This multi-part, multi-method installation and fixing method, involving sidewall glass wool 31, top cover glass wool 33, and bottom wall glass wool 32, ensures a tight fit between the glass wool and various parts of the tank, reducing air gaps and improving insulation efficiency. Simultaneously, the high-temperature resistant adhesive and welding methods ensure the stability of the glass wool during use, preventing it from easily falling off and extending the service life of the insulation component. Several reinforcing ribs 34 are fixedly installed on the side of the sidewall glass wool 31 away from the tank body 2. The length of the reinforcing ribs 34 is the same as the height of the sidewall glass wool 31, and the reinforcing ribs 34 are integrally formed with the sidewall glass wool 31. The reinforcing ribs 34 can effectively enhance the overall structural strength of the sidewall glass wool 31, prevent the sidewall glass wool 31 from deforming or being damaged under its own weight or external pressure, ensure the structural integrity of the sidewall glass wool 31, and thus maintain its good thermal insulation performance.
[0036] Figures 1-6 The outer protective assembly 4 shown includes a protective shell 41 and a sealing strip 42. The protective shell 41 is fitted onto the outer surface of the tank body 2 and several side wall glass wool 31. The top of the protective shell 41 abuts against one side of the flange 6 fixed to the tank body 2, and the bottom of the protective shell 41 is fixedly connected to one side of the support base 1. One side of the sealing strip 42 is fixedly installed on one side of the protective shell 41, and the other side abuts against one side of the flange 6 fixed to the tank body 2. The protective shell 41 effectively protects the inner side wall glass wool 31 from external environmental erosion, while the sealing strip 42 enhances the sealing between the protective shell 41 and the flange 6, ensuring the airtightness of the insulation cavity and further improving the insulation effect. Several support protrusions are fixedly installed on the inner wall of the protective shell 41. One side of the support protrusion abuts against the outer surface of the side wall glass wool 31 and is inserted between two adjacent reinforcing ribs 34. The support protrusions are integrally formed with the protective shell 41. The supporting protrusions can effectively support the side wall glass wool 31, preventing the protective shell 41 from excessively squeezing the side wall glass wool 31 during installation or use. At the same time, the design of inserting between adjacent reinforcing ribs 34 can limit the relative displacement between the protective shell 41 and the side wall glass wool 31, ensuring the stability of the structure and also helping to maintain the structure of the insulation cavity.
[0037] Figures 1-6The support base 1 shown has a hollow insulation cavity between its inner wall bottom and the storage tank body 2. Several support legs 10 are fixedly installed at the bottom of the support base 1. The hollow insulation cavity reduces heat exchange between the bottom of the storage tank body 2 and the outside environment, enhancing the insulation effect of the bottom of the storage tank. The support legs 10 provide stable support for the entire storage tank, raising the tank and preventing the bottom of the storage tank from directly contacting the ground, thus reducing the impact of the ground environment on the temperature of the storage tank.
[0038] Figures 1-6 The insulation cavity between the support base 1 and the tank body 2 is filled with insulation cotton 8. The insulation cotton 8 further fills the internal space of the insulation cavity, reducing air convection and enhancing its insulation performance. This improves the overall insulation effect at the bottom of the tank, making the insulation of all parts of the tank more uniform and reliable. A sealing gasket 7 is installed in the connection gap between the two flanges 6. Lifting lugs 9 are symmetrically fixed to the top of the tank cover 5, with one end of each lug penetrating one side of the top cover glass wool 33. The sealing gasket 7 enhances the seal between the tank cover 5 and the tank body 2, preventing the evaporation of acrylic acid inside the tank or the entry of outside air, ensuring the tank's sealing performance. The lifting lugs 9 facilitate the lifting operation of the tank cover 5, making it easy to install and remove, thus improving the convenience of using the tank.
[0039] Working Principle: During operation, the acrylic storage tank with its insulated structure is first stably supported by the support base 1. The support legs 10 at the bottom of the support base 1 further enhance the stability of the equipment in different ground environments. Simultaneously, the insulation cotton 8 filling the insulation cavity between the support base 1 and the tank body 2 provides insulation and protection for the bottom of the tank body 2, reducing heat loss from the bottom. Next, acrylic material is injected into the top-opening tank body 2. The bottom wall glass wool 32 welded and fixed inside the tank body 2 directly contacts the material, providing initial insulation and preventing rapid temperature changes. Then, the tank cover 5 is placed on top. The tank cover 5 and the tank body 2 are detachably connected via flanges 6 using bolts and nuts. The sealing gasket 7 placed in the gap between the two flanges 6 effectively enhances the sealing of the connection, preventing material leakage and the entry of outside air. The outer surface of the tank cover 5 is fixed with a high-temperature resistant adhesive. The fixed top cover glass wool 33 and the several side wall glass wool 31 fixed to the outer surface of the storage tank body 2 with high temperature resistant adhesive can form an all-round heat insulation layer from the outer surface of the storage tank body 2 and the tank cover 5, ensuring the durability of the heat insulation effect. The protective shell 41 can provide uniform support for the side wall glass wool 31, avoiding damage to the side wall glass wool 31 due to long-term uneven stress. At the same time, a sealed heat insulation cavity is formed between the protective shell 41 and the outer surface of the storage tank body 2. This cavity can form a double heat insulation structure together with the inner heat insulation component 3, which greatly reduces the heat exchange between the inside of the storage tank and the outside, ensuring that the acrylic material is always in a suitable temperature environment and ensuring the quality stability of the material. In the whole process, the components work together to achieve effective storage of acrylic material, and through multi-layer heat insulation and sealing design, improve the heat insulation effect and safety of the equipment, and meet the process requirements for long-term storage of acrylic material.
[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
