Description

Technical Field

[0001] This utility model relates to the field of asphalt storage technology, and in particular to a special asphalt constant temperature storage tank. Background Technology

[0002] Specialty asphalt is an asphalt material processed using special techniques, possessing excellent properties such as high-temperature resistance, low-temperature resistance, aging resistance, and fatigue resistance. It is commonly used in the construction and maintenance of heavy-duty transportation facilities such as highways, bridges, and airports, effectively improving road surface service life and driving safety. Compared to ordinary asphalt, specialty asphalt has higher requirements in terms of component ratios, production processes, and performance indicators to meet the specific engineering and environmental conditions required for its use.

[0003] While existing special asphalt constant temperature storage tanks can basically achieve the storage function during the storage process, the uneven temperature distribution inside the tank leads to a significant temperature difference between the asphalt near the inner wall and the center, which can easily cause local overheating or undercooling and affect the storage effect. Although a stirring mechanism is used to try to achieve uniform heating through timed stirring, its effect is limited by factors such as the size of the stirring blades. Simple stirring driven by a motor cannot be adaptively adjusted, resulting in poor uniformity and still failing to completely solve the problem of uneven temperature distribution. Utility Model Content

[0004] One objective of this invention is to provide a special asphalt constant temperature storage tank. This invention addresses the problem that existing special asphalt constant temperature storage tanks, as mentioned in the background, while basically achieving the storage function, suffer from uneven temperature distribution within the tank. This results in a significant temperature difference between the asphalt near the inner wall and the center, easily leading to localized overheating or undercooling, thus affecting the storage effect. Although a stirring mechanism is used to attempt to achieve uniform heating through timed stirring, its effectiveness is limited by factors such as the size of the stirring blades. Simple stirring driven by a motor cannot adaptively adjust, resulting in poor uniformity and failing to completely solve the problem of uneven temperature distribution.

[0005] A special asphalt constant temperature storage tank according to an embodiment of the present utility model includes:

[0006] A storage assembly includes an inner tank and an outer tank that is wrapped around the outer side of the inner tank, with a heating wire installed between the inner tank and the outer tank;

[0007] A mixing mechanism, installed inside the inner tank of the storage assembly, is used to ensure that the asphalt is heated evenly during storage. The mixing mechanism includes a drive shaft disposed inside the inner tank. A first bevel gear is fixedly disposed on the outer side of the drive shaft from top to bottom. A second bevel gear is symmetrically meshed with the top of the first bevel gear. A mounting bracket is fixedly disposed at the tail end of the second bevel gear. A detachable mixing blade is fixedly disposed inside the mounting bracket. The blade is rotatably connected to the outer shell through the mounting bracket to achieve positioning and rotation. A scraping assembly is installed on the top of the outer shell and located on the inner wall of the inner tank. The drive shaft and the scraping assembly are both rotated relative to each other through a drive mechanism.

[0008] Preferably, the heating wires are circular and there are several of them.

[0009] Preferably, a feed hopper and a discharge hopper are fixedly installed at the upper and lower ends of the inner tank, respectively, and a control valve is fixedly installed on the outer side of the discharge hopper.

[0010] Preferably, the bottom of the outer can is circular and is fixedly provided with support legs.

[0011] Preferably, the drive shaft is rotatably connected to the inner tank via a bearing housing.

[0012] Preferably, the scraper assembly includes an L-shaped bracket fixed to the outside of the outer shell, and a scraper is fixedly provided at one end of the L-shaped bracket that fits against the inner wall of the inner tank.

[0013] Preferably, the drive mechanism includes a servo motor, with a support frame and a fifth bevel gear fixedly mounted on one end and the output end of the servo motor, respectively. A third bevel gear and a fourth bevel gear are meshed on the upper and lower ends of one side of the fifth bevel gear, respectively. The third bevel gear is fixed to the top of the drive shaft, and a sleeve is fixedly mounted on the bottom end of the fourth bevel gear. The sleeve is fixed to the top of the outer casing.

[0014] Preferably, the servo motor is fixed to the top of the outer tank by a shim block.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problem of uneven asphalt temperature distribution in existing technologies by setting up a stirring mechanism and a driving mechanism. During use, the stirring mechanism and the driving mechanism work together. The servo motor in the driving mechanism drives the fifth bevel gear to rotate, which in turn causes the third bevel gear connected to the drive shaft to rotate in the opposite direction to the fourth bevel gear connected to the scraper assembly and the outer shell. At this time, the drive shaft drives the first bevel gear to rotate, causing the meshing second bevel gear to drive the mounting frame and stirring blades to rotate around their own axis. After the sleeve rotates in the opposite direction, it drives the L-shaped bracket and scraper of the scraper assembly to scrape synchronously along the inner wall of the inner tank, forming a compound action of bidirectional dynamic stirring and inner wall cleaning. This ensures that the asphalt is heated evenly during storage, effectively avoids local overheating or overcooling, and improves the storage effect.

[0017] This utility model, through its storage component, allows the evenly distributed heating wires to wrap around the inner tank via a sandwich structure between the inner and outer tanks, providing a comprehensive heating effect. Furthermore, the outer shell provides insulation, preventing burns to workers and avoiding overheating or cooling that could affect the storage of the special asphalt. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A special type of constant-temperature asphalt storage tank, comprising:

[0026] Storage component 1 includes an inner tank 101 and an outer tank 104 that wraps around the inner tank 101. A heating wire 102 is installed between the inner tank 101 and the outer tank 104. Through the sandwich structure between the inner and outer tanks, the storage component enables the annularly distributed heating wire to evenly surround the inner tank, providing an all-round heating effect. The outer shell can also provide thermal insulation, preventing burns to workers and avoiding overheating or cooling that could affect the storage of special asphalt.

[0027] A mixing mechanism 2, installed inside the inner tank 101 of the storage assembly 1, is used to ensure that the asphalt is heated evenly during storage. The mixing mechanism 2 includes a drive shaft 201 located inside the inner tank 101. First bevel gears 203 are fixedly mounted on the outer side of the drive shaft 201 from top to bottom. Second bevel gears 204 are symmetrically meshed with the top of the first bevel gears 203. A mounting bracket 205 is fixedly mounted at the tail end of the second bevel gears 204. Removable mixing blades 206 are fixedly mounted inside the mounting bracket 205. The blades are rotatably connected to the outer shell 207 via the mounting bracket 205 to achieve positioning and rotation. A scraping assembly is mounted on the top of the outer shell 207, located on the inner wall of the inner tank 101. The scraping assembly includes components fixed to the outer shell. An L-shaped bracket 209 is attached to the outer side of the 207. A scraper 210 is fixedly installed at one end of the L-shaped bracket 209 that fits against the inner wall of the inner tank 101. The drive shaft 201 and the scraper assembly are both rotated relative to each other by the drive mechanism 3. The drive mechanism 3 includes a servo motor 305. A support frame 304 and a fifth bevel gear 303 are fixedly installed at one end and the output end of the servo motor 305, respectively. A third bevel gear 301 and a fourth bevel gear 302 are meshed at the upper and lower ends of one side of the fifth bevel gear 303, respectively. The third bevel gear 301 is fixed to the top of the drive shaft 201. A sleeve 208 is fixedly installed at the bottom of the fourth bevel gear 302. The sleeve 208 is fixed to the top of the outer shell 207. In use, the stirring mechanism and the drive mechanism work together. The servo motor in the drive mechanism drives the fifth bevel gear to rotate, which in turn causes the third bevel gear connected to the drive shaft to rotate in the opposite direction to the fourth bevel gear connected to the scraper assembly and the outer shell. At this time, the drive shaft drives the first bevel gear to rotate, causing the meshing second bevel gear to drive the mounting bracket and the mixing blade to rotate around its own axis. After the sleeve rotates in the opposite direction, it drives the L-shaped bracket and scraper of the scraper assembly to scrape synchronously along the inner wall of the inner tank, forming a compound action of bidirectional dynamic mixing and inner wall cleaning. This ensures that the asphalt is heated evenly during storage, effectively avoids local overheating or overcooling, and improves the storage effect.

[0028] Example 1: Several circular heating wires 102 are evenly arranged around each other to ensure comprehensive and uniform heating. The upper and lower ends of the inner tank 101 are respectively fixedly provided with a feed hopper 105 and a discharge hopper 106. A control valve 107 is fixedly provided on the outside of the discharge hopper 106 to facilitate precise control of the asphalt in and out. The bottom of the outer tank 104 is circularly provided with support legs 103 to provide stable support.

[0029] Example 2: The drive shaft 201 is rotatably mounted to the inner tank 101 via the bearing seat 202, ensuring the flexible operation of the mixing mechanism. The servo motor 305 is fixed to the top of the outer tank 104 via the shim block 306. When the servo motor is started, the drive shaft drives the mixing mechanism to rotate, achieving uniform mixing of asphalt. This design effectively improves mixing efficiency, avoids the problem of uneven asphalt temperature distribution, and is easy to maintain and adjust, making it suitable for the storage needs of special asphalt under various complex working conditions.

[0030] Working principle: First, the storage component 1 includes an inner tank 101 and an outer tank 104, with several circular heating wires 102 evenly surrounding it to provide all-around heating. Simultaneously, the outer tank serves as insulation, ensuring safety and the quality of asphalt storage. The mixing mechanism 2 is installed inside the inner tank 101, and the drive shaft 201 is rotatably connected to the inner tank via a bearing seat 202 to ensure flexible operation. The servo motor 305 is fixed to the top of the outer tank and stably supported by a shim block 306, providing power to the mixing mechanism. During operation, the servo motor drives the fifth bevel gear 303 to rotate, causing the third bevel gear 301 and the fourth bevel gear 302 to rotate in opposite directions. The drive shaft then drives the first bevel gear 203 to rotate. This allows the second bevel gear 204 and the stirring blades 206 inside the mounting bracket 205 to achieve positioning and rotation, ensuring uniform heating of the asphalt. At the same time, the sleeve 208 rotates in the opposite direction, driving the L-shaped bracket 209 and scraper 210 of the scraper assembly to scrape synchronously along the inner wall of the inner tank, achieving bidirectional dynamic stirring and inner wall cleaning, further ensuring uniform asphalt temperature. In addition, the inner tank is equipped with a feed hopper 105 and a discharge hopper 106 at the upper and lower ends, and a control valve 107 is provided on the outside of the discharge hopper to facilitate precise control of asphalt entry and exit. The bottom of the outer tank is evenly distributed with support legs 103 to provide stable support, thereby effectively avoiding the problem of uneven asphalt temperature distribution, improving storage effect, and suitable for special asphalt storage needs under various complex working conditions.
