Description

Technical Field

[0001] This invention relates to the field of auxiliary processing equipment for waterproof membranes, specifically, a modular asphalt insulation storage tank. Background Technology

[0002] Asphalt is an important material for road and bridge construction and waterproofing. During its production and transportation, the proper insulation and storage of raw materials is crucial for ensuring quality and reducing energy consumption. Currently, most asphalt storage tanks widely used in industrial applications are integrally welded cylindrical vertical fixed-roof tanks. In practice, especially when dealing with high-viscosity, easily solidifying, and temperature-sensitive modified or specialty asphalt raw materials, the structural design of these traditional tanks has revealed several technical bottlenecks that urgently need to be addressed, primarily in terms of insulation performance and structural maintenance.

[0003] Firstly, regarding thermal insulation and energy saving, traditional storage tanks use a uniformly thick insulation layer to wrap the tank walls and top. However, the heat loss distribution in actual operation is extremely uneven. Due to hydrostatic pressure, the density of the asphalt inside the tank is slightly higher at the bottom than at the top, and the bottom heating coils are usually concentrated. If heat replenishment is uneven, it can easily lead to a significant temperature difference between the upper and lower layers, accelerating the sedimentation of the modifier. A uniform insulation layer design is clearly an "egalitarian" and crude solution. As a result, to meet the insulation requirements of the most demanding parts, the overall insulation layer is forced to be thicker, leading to increased materials and costs, while the insulation capacity of the upper part is relatively excessive, resulting in low system energy efficiency. This structural design flaw is one of the fundamental reasons restricting the economic efficiency of storage tank operation.

[0004] Secondly, regarding structural maintainability, the integral welded tank structure presents a maintenance challenge due to the need for complete replacement. Storage tanks are exposed to high temperatures and corrosive gases over extended periods, making localized areas more susceptible to corrosion, leakage, or water immersion failure of the insulation layer. In the event of such localized damage, current technologies often require emptying the tank, undertaking large-scale or even complete dismantling, repair, and redoing of the insulation—a time-consuming and costly process, with construction quality heavily influenced by site conditions. This indivisible, integral nature results in long maintenance cycles, high costs, and difficulty in optimizing lifecycle costs. Summary of the Invention

[0005] The purpose of this invention is to provide a modular asphalt insulated storage tank, which systematically solves the problems of poor insulation effect, high cost, and high maintenance cost through the design of a gradient variable thickness insulation structure and a modular composite tank structure.

[0006] To solve the above problems, the present invention employs the following technical means: A modular asphalt insulated storage tank, comprising: The bottom storage segment, serving as the bottom end, has a first insulation layer constructed on its sidewalls; The middle storage section, as the middle part, has a second insulation layer on its side walls; The top storage section has an adjustable cover plate at the top, which serves as the top, and the side walls have a third insulation layer. The middle storage segment is connected to the bottom storage segment via a first connecting mechanism, and the middle storage segment is connected to the top storage segment via a second connecting mechanism. The first insulation layer is constructed as a first equal-width annular layer, the second insulation layer is constructed as a variable-diameter annular layer with a decreasing diameter from bottom to top, and the third insulation layer is constructed as a second equal-width annular layer. The thickness of the third insulation layer does not exceed the minimum thickness of the second insulation layer, and the maximum thickness of the second insulation layer does not exceed the thickness of the first insulation layer.

[0007] Preferably, the bottom storage section is closed at its bottom end and connected to a discharge mechanism at its bottom end, while the top end of the bottom storage section is open and connected to the bottom end of the middle storage section.

[0008] Furthermore, both ends of the middle storage segment are open, with the top end used to communicate with the top storage segment and the bottom end used to communicate with the bottom storage segment.

[0009] Furthermore, a first retaining ring is coaxially mounted on the inner wall of the bottom end of the middle storage section. The first retaining ring extends into the bottom storage section, and the outer wall of the first retaining ring abuts and fits against the inner wall of the bottom storage section.

[0010] Furthermore, the connection point between the top of the first retaining ring and the middle storage segment is constructed with an arc-shaped chamfer structure.

[0011] Furthermore, the top storage segment includes a tube extending through both ends, a third insulation layer disposed on the side wall of the tube, an adjusting cover plate coaxially disposed at the top of the tube, a bearing plate coaxially disposed inside the tube, a screw threadedly mounted on the bearing plate, the screw extending upward and rotating through the adjusting cover plate and coaxially connected to the rotating end of a rotating motor, the rotating motor being fixedly mounted on the outer top surface of the adjusting cover plate, a vertically extending limiting groove constructed on the side wall of the tube, and a limiting block slidably disposed within the limiting groove mounted on the outer wall of the adjusting cover plate.

[0012] Furthermore, the support plate includes a mounting plate for threaded connection with the screw, and a horizontal connecting rod is arranged around the outer edge of the mounting plate, the other end of the connecting rod being connected to the inner wall of the tube.

[0013] Furthermore, a second retaining ring is coaxially installed on the inner wall of the bottom end of the tube. The second retaining ring extends into the middle storage section. The outer wall of the second retaining ring is separated from the inner wall of the middle storage section. A sealing ring is installed on the inner wall of the top end of the middle storage section. The inner ring wall of the sealing ring is fitted with the outer wall of the second retaining ring.

[0014] Furthermore, the first connecting machine includes a first female groove coaxially disposed at the top of the bottom storage segment and a first male block disposed at the bottom of the middle storage segment. The first male block is inserted into the first female groove, and a horizontal first bolt is installed on the bottom storage segment, the first bolt passing through the first female groove and the first male block.

[0015] Furthermore, the two-connector includes a second female groove coaxially disposed at the top of the middle storage section and a second male block disposed at the bottom of the top storage section. The second male block is inserted into the second female groove, and a horizontal second bolt is installed on the middle storage section, the second bolt passing through the second female groove and the second male block.

[0016] The present invention has the following beneficial effects during use: This invention employs a gradient-thickness insulation design based on heat flux density analysis. Specifically, the tank wall insulation layer adopts a three-dimensional configuration of "thinner at the top and thicker at the bottom" according to the natural distribution of heat dissipation intensity, constructing a high-strength "thermal barrier" in the lower part of the tank where heat dissipation is strongest and where it connects to the foundation. Simultaneously, by setting different first, second, and third insulation layers, a three-dimensional temperature control system is formed on the sidewalls, precisely controlling the axial and radial temperature differences within the tank to a very small range. This completely eliminates the problems of modifier segregation and uneven asphalt thermal aging caused by large temperature differences between the top and bottom of traditional storage tanks, providing a fundamental guarantee for the long-term stable storage of high-quality specialty asphalt.

[0017] Furthermore, this invention deconstructs large storage tanks from indivisible monolithic equipment into standardized prefabricated functional modules. This ensures optimal insulation and sealing performance for each module. On-site, modules are connected via a first or second connecting mechanism, enabling rapid and high-quality assembly unaffected by weather or welder skills. This modular design allows for partial replacement of the tank. When a part of the tank is damaged, there is no need to clean the tank and stop production; only the faulty module needs to be disassembled and replaced, greatly improving asset availability and operational flexibility.
