Description

Technical Field

[0001] The utility model belongs to the field of asphalt transportation, and particularly relates to a transportation and storage device for anti-stratification asphalt materials. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives, mostly existing in the form of liquid or semi-solid petroleum. Since the heavy components in asphalt may precipitate to the bottom and stratify under static or low-temperature conditions, resulting in uneven performance of asphalt and affecting the final construction quality, special asphalt storage tanks are required for asphalt transportation, and stirring and heat preservation means are used to prevent stratification during transportation.

[0003] In the prior art, the heating structure of a conventional asphalt transportation storage tank is often arranged on the inner wall of the tank, and heat is conducted from the outside to the inside to heat the asphalt. There are problems such as poor heating effect, and the asphalt in each part of the tank is still likely to stratify due to uneven heating. At the same time, due to the high viscosity of asphalt, some asphalt will still remain on the inner wall of the tank and cannot be fully discharged during the process of discharging asphalt, resulting in a large amount of asphalt loss and increasing the burden of cleaning work.

[0004] Therefore, in view of the problems that asphalt is prone to stratification during transportation and the asphalt inside the storage tank is not easily fully discharged, a transportation and storage device for anti-stratification asphalt materials is proposed. By setting a stirring structure with an internal heating component, while ensuring the fluidity of asphalt by stirring, the temperature of the asphalt storage environment can be controlled to avoid asphalt stratification caused by temperature changes. Content of the Utility Model

[0005] In order to overcome the problems that during the transportation of asphalt, asphalt is prone to stratification due to temperature changes, resulting in quality decline, and at the same time, the asphalt inside the storage tank is not easily fully discharged.

[0006] The technical solution of the utility model is as follows: A transportation and storage device for anti-stratification asphalt materials, including a storage tank; a first motor is fixedly connected to the left end of the storage tank; the output shaft of the first motor passes through the right end of the storage tank and extends into the interior of the storage tank; the outer wall of the output shaft of the first motor is fixedly connected with stirring blades evenly distributed in a circle; both the output shaft of the first motor and the stirring blades are hollow structures inside; the internal spaces of the output shaft of the first motor and the stirring blades are connected; a heating component is arranged inside the output shaft of the first motor; the heating component includes an oil injection hole, an oil sealing bolt, a heating pipe, and heat-conducting oil; the outer wall of the output shaft of the first motor is fixedly connected with the oil injection hole in a penetrating manner; the inner wall of the oil injection hole is threadedly installed with the oil sealing bolt; the inner wall of the output shaft of the first motor is fixedly connected with the heating pipe; the internal spaces of the output shaft of the first motor and the stirring blades are filled with heat-conducting oil; a scraping component is arranged inside the storage tank.

[0007] Preferably, during the transportation of asphalt, the stirring blades are driven by the first electric motor to continuously stir the asphalt to ensure its fluidity. At the same time, the temperature controller controls the heating tube installed inside the output shaft of the first electric motor to heat the heat-conducting oil. The generated heat will be evenly conducted to the asphalt stored in the storage tank to ensure the constancy of the asphalt temperature and prevent the asphalt from stratifying. After the asphalt is preliminarily discharged completely through the high-temperature ball valve, the scraping assembly is started. The residual asphalt on the inner wall of the storage tank is scraped off by the rubber scraping blade and conveyed to the high-temperature ball valve to ensure the full discharge of the asphalt.

[0008] Preferably, the scraping assembly includes a second electric motor, a lead screw, bearing seats, a lead screw nut, a slip ring, rolling beads and a rubber scraping blade. The second electric motor is fixedly connected to the left end of the storage tank. The output shaft of the second electric motor passes through the left end of the storage tank and is fixedly connected to the lead screw. The left and right end faces of the inner wall of the storage tank are fixedly connected with bearing seats symmetrically distributed about the center of the storage tank. The inner walls of the two bearing seats are jointly rotatably installed with the lead screw. The outer wall of the lead screw is movably installed with the lead screw nut. The lower end of the lead screw nut is fixedly connected to the slip ring. The outer wall of the slip ring is rotatably installed through a plurality of rolling beads evenly distributed in a circumferential manner. The outer walls of the rolling beads are in contact with the inner wall of the storage tank. The right end of the slip ring is fixedly connected to the rubber scraping blade. The rubber scraping blade is of an annular structure and its outer diameter is larger than that of the slip ring. The outer wall of the rubber scraping blade is in contact with the inner wall of the storage tank. Through the setting of the scraping assembly, when it is necessary to discharge the asphalt inside the storage tank, the second electric motor is started. The output shaft of the second electric motor will drive the lead screw to rotate synchronously, so that the lead screw nut slides smoothly along the outer wall of the lead screw, driving the slip ring to move synchronously. The sliding of the rolling beads on the inner wall surface of the storage tank helps to reduce the resistance suffered by the slip ring when sliding on the inner wall of the storage tank. Through the setting of the rubber scraping blade, it helps to scrape off the residual asphalt on the inner wall of the storage tank, ensuring that the asphalt can be discharged from the storage tank more thoroughly and avoiding the influence on subsequent use caused by the solidification of the asphalt on the inner wall of the storage tank.

[0009] Preferably, the lower end of the storage tank is fixedly connected with support bases symmetrically distributed about the center of the storage tank. The upper ends of the support bases are fixedly connected with lifting rings symmetrically distributed about the center of the storage tank. Through the setting of the support bases and the lifting rings, it helps to hoist the entire equipment onto the transport vehicle for installation and fixation by a crane, with a wider applicability.

[0010] Preferably, a temperature controller is fixedly connected to the right end of the storage tank. The temperature controller is electrically connected to the heating tube. Since different types of asphalt have different transportation temperature requirements, usually high-viscosity asphalt is transported at a higher temperature, while low-viscosity asphalt is transported at a lower temperature. Through the setting of the temperature controller, it can be adjusted according to environmental influences and the type of asphalt to ensure that the asphalt will not be stratified due to temperature during transportation.

[0011] Preferably, a high-temperature ball valve is fixedly connected to the right end of the storage tank in a penetrating manner; the liquid inlet end of the high-temperature ball valve is located at the lower edge of the inner right end face of the storage tank; through the setting of the high-temperature ball valve, it is convenient to realize the loading and discharging of asphalt, and the high-temperature ball valve can withstand high-temperature environments and the corrosion of asphalt, preventing damage or leakage of the valve itself.

[0012] Preferably, a maintenance manhole is fixedly connected to the left end of the storage tank in a penetrating manner; through the setting of the maintenance manhole, a passage for entering the interior of the storage tank for inspection, cleaning, and maintenance is provided. Since asphalt may produce precipitation or residues during transportation, the interior of the storage tank is regularly cleaned and inspected to ensure safe operation and maintain the quality of asphalt.

[0013] Preferably, the output shaft of the first motor and the stirring blades are made of copper-aluminum alloy; by making the output shaft of the first motor and the stirring blades of copper-aluminum alloy, copper-aluminum alloy has a very high thermal conductivity, which helps to conduct the internal heat to the asphalt. At the same time, copper-aluminum alloy usually has good corrosion resistance and mechanical properties, and can resist the corrosion of asphalt.

[0014] Advantages of the present utility model:

[0015] 1. During the transportation of asphalt, the first motor drives the stirring blades to continuously stir the asphalt to ensure the fluidity of the asphalt. At the same time, the temperature controller controls the heating tube installed inside the output shaft of the first motor to heat the heat-conducting oil, and the generated heat will be evenly conducted to the asphalt stored in the storage tank to ensure the constancy of the asphalt temperature and prevent the asphalt from stratifying. Compared with the conventional method of heating asphalt from the outside of the storage tank, the contact area between the stirring blades and the asphalt is larger, and the heat conduction is faster and more uniform, solving the problem that asphalt is prone to stratification due to temperature changes, resulting in a decline in quality.

[0016] 2. Through the setting of the scraping assembly, when it is necessary to discharge the asphalt inside the storage tank, the second motor is started. The output shaft of the second motor will drive the lead screw to rotate synchronously, so that the nut sleeve slides smoothly along the outer wall of the lead screw, driving the sliding ring to move synchronously. The sliding of the rotating ball on the inner wall surface of the storage tank helps to reduce the resistance suffered by the sliding ring when sliding on the inner wall of the storage tank. Through the setting of the rubber scraping blade, it helps to scrape off the residual asphalt on the inner wall of the storage tank, ensuring that the asphalt can be discharged from the storage tank more thoroughly and avoiding the influence of the solidification of asphalt on the inner wall of the storage tank on subsequent use.

[0017] 3. Through the setting of the maintenance manhole, a passage for entering the interior of the storage tank for inspection, cleaning, and maintenance is provided. Since asphalt may produce precipitation or residues during transportation, the interior of the storage tank is regularly cleaned and inspected to ensure safe operation and maintain the quality of asphalt.
