Description

Technical Field

[0001] This utility model relates to the technical field of asphalt liquid storage equipment, specifically to an asphalt liquid heat preservation and storage device, which is particularly suitable for asphalt liquid application scenarios that require long-term heat preservation and storage and prevention of stratification and sedimentation. Background Technology

[0002] During storage, asphalt liquid is susceptible to stratification, sedimentation, and decreased fluidity due to the susceptibility of its main components to temperature changes and static conditions, thus affecting its subsequent use. Existing asphalt liquid storage devices typically include a tank, an insulation jacket, and a mixing assembly, but these devices suffer from the following key problems: The lack of an effective internal flow guidance and circulation mechanism limits the ability to prevent stratification: Existing devices typically rely solely on agitation components to disturb the asphalt solution, without a dedicated flow guidance structure. During agitation, the asphalt solution exhibits a single flow pattern, making it difficult to form a systematic internal circulation, with dead zones particularly prone to forming at the bottom of the tank. This results in stratification of the asphalt solution components even during static storage, with solid substances gradually settling, affecting the uniformity and performance of the asphalt solution.

[0003] This deficiency limits the applicability of existing asphalt storage devices in applications where long-term material homogeneity needs to be maintained. Utility Model Content

[0004] To overcome the problem that existing asphalt liquid storage devices lack an effective internal guiding and circulation mechanism, leading to easy stratification and sedimentation of asphalt liquid and affecting storage quality, this utility model provides an asphalt liquid heat preservation storage device. By setting a guide tube in conjunction with an agitator with a diameter decreasing from top to bottom, and utilizing the hollow structure of the guide tube to assist heating, the asphalt liquid is forced to circulate within the tank, effectively preventing stratification and sedimentation, and improving heat preservation uniformity and stirring effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an asphalt liquid heat preservation and storage device, including a tank body, arranged vertically, for containing asphalt liquid; a tank cover, detachably connected to the tank body; a jacket, fitted outside the tank body, forming a closed accommodating space between the jacket and the outer wall of the tank body, the jacket being provided with an oil inlet and an oil outlet; a stirring assembly, disposed inside the tank body, including a motor, a shaft, multiple agitators and a rod seat, the motor being disposed on the tank cover, the shaft being driven by the motor and extending vertically downward into the tank body, the multiple agitators being arranged at intervals along the axial direction of the shaft, the end of the shaft being hinged to a rod seat fixed inside the tank body; and a guide tube, which is a straight cylindrical structure open at both ends, fixedly disposed inside the tank body and adapted to the agitator at the lowest end, for circulating the asphalt liquid inside and outside the guide tube during stirring.

[0006] In the aforementioned asphalt liquid heat preservation and storage device, the stirring diameter of the agitator decreases sequentially from top to bottom.

[0007] In the aforementioned asphalt liquid heat preservation and storage device, the guide tube is fixedly connected to the inner wall of the tank by a support rod extending from its outer wall.

[0008] The aforementioned asphalt liquid heat preservation and storage device has a hollow guide tube with a heat transfer oil inlet and a heat transfer oil outlet on its wall.

[0009] In the aforementioned asphalt liquid heat preservation and storage device, the jacket is connected to the outer wall of the tank by welding.

[0010] In the aforementioned asphalt liquid heat preservation and storage device, the oil inlet is vertically arranged at the bottom of the jacket, and the oil outlet is horizontally arranged on the side of the jacket.

[0011] The aforementioned asphalt liquid heat preservation and storage device has asphalt liquid inlets symmetrically arranged on both sides of the horizontal direction of the tank.

[0012] The aforementioned asphalt liquid heat preservation and storage device has at least one asphalt liquid outlet spaced at intervals at the bottom of the vertical direction of the tank.

[0013] The aforementioned asphalt liquid heat preservation and storage device has a tank made of a high-temperature resistant and corrosion-resistant metal material.

[0014] The beneficial effects of this utility model are: 1. By setting up a guide tube that is compatible with the agitator, the asphalt liquid is forced to form a systematic circulation flow inside and outside the tube, effectively preventing stratification and sedimentation.

[0015] 2. The hollow structure design of the guide tube allows the introduction of heat transfer oil, which enhances the fluidity and temperature uniformity of the asphalt liquid at the bottom of the tank.

[0016] 3. The impeller layout with decreasing diameter from top to bottom ensures that the stirring action matches the shape of the tank, improving the overall stirring efficiency and effect. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments and examples.

[0020] This application relates to a thermal insulation and storage device for asphalt liquid, such as... Figure 1 As shown, the device mainly consists of a tank body 6, a tank cover 11, a jacket 5, a stirring assembly, and supporting inlet / outlet ports 2, heat transfer oil inlet / outlet ports, etc. The tank body 6 is vertically arranged to contain asphalt liquid. The tank cover 11 can be vertically separated and connected to the tank body 6 by bolts for easy inspection and maintenance. The jacket 5 is fitted onto the outside of the tank body 6 and is firmly connected to the outer wall of the tank body 6 by welding to form a closed containment space, which is filled with heat transfer oil to achieve the heat preservation function. The stirring assembly is set inside the tank body 6 to prevent the asphalt liquid from stratifying and settling. The tank body 6 is made of high-temperature resistant and corrosion-resistant metal materials to adapt to the high temperature and chemical properties of the asphalt liquid.

[0021] The jacket 5 has a vertically arranged oil inlet 1 at the bottom for injecting heat transfer oil into the jacket 5; the jacket 5 has a horizontally arranged oil outlet 13 on the side for discharging heat transfer oil, realizing the circulation and renewal of heat transfer oil. In practical applications, the heat transfer oil can be heated by external heating equipment. The heated heat transfer oil enters the jacket 5 through the oil inlet 1, exchanges heat with the tank 6, and is discharged from the oil outlet 13, returning to the heating equipment for reheating, forming a cycle.

[0022] Asphalt liquid inlets 10 are symmetrically arranged on both sides of the horizontal direction of the tank body 6, which facilitates the rapid and uniform entry of asphalt liquid into the tank body 6. The size of the inlets 10 is designed according to the actual feed flow requirements to ensure smooth feeding process. Asphalt liquid outlets 2 are arranged at intervals at the bottom of the vertical direction of the tank body 6 to discharge the stored asphalt liquid. The arrangement and number of outlets 2 can be adjusted according to actual use requirements to meet the discharge requirements in different scenarios.

[0023] The stirring assembly is one of the core components of this storage device, mainly including a motor 12, a shaft 9, an agitator 7, a rod holder 4, and a guide tube 8. The motor 12 is vertically arranged at the top center of the tank cover 11, providing power to the entire stirring assembly. A high-power, high-temperature resistant model of motor 12 is selected to meet the high-temperature requirements of the asphalt liquid storage environment. The output end of the motor 12 is connected to a shaft 9 extending vertically downward inside the tank body 6 via a coupling. The shaft 9 is made of high-strength metal material, with good rigidity and toughness, and can withstand the torque generated during the stirring process. The end of the shaft 9 is hinged to a rod seat 4 that is fixedly connected to the inside of the tank 6. The rod seat 4 supports the shaft 9 and ensures the stability of the shaft 9 during rotation. Multiple agitators 7 are arranged at intervals along the axial direction on the upper part of the shaft 9. The stirring diameter of the agitators 7 decreases from top to bottom. This design is to match the inner diameter of the tank 6 so that the agitators 7 can effectively stir the asphalt liquid at different heights and prevent the asphalt liquid from stratifying and settling. The shape of the agitators 7 can be optimized according to the actual stirring effect. Common types include propeller type and turbine type.

[0024] To further reduce the deposition of asphalt liquid at the bottom of tank 6, a guide tube 8 adapted to the bottommost agitator 7 is added inside tank 6. The guide tube 8 is a straight cylindrical structure with openings at both ends. Its outer wall extends with a support rod that is fixedly connected to the inner wall of tank 6. The support rod firmly fixes the guide tube 8 inside tank 6. When the agitator 7 rotates, the asphalt liquid inside the guide tube 8 will generate a vortex, thereby creating a pressure difference between the asphalt liquid on the outside of the guide tube 8 and the asphalt liquid between tank 6. This pressure difference causes the asphalt liquid to continuously enter the guide tube 8 from the bottom and flow from the top of the guide tube 8 to the space between tank 6 and guide tube 8, promoting the circulation of asphalt liquid inside tank 6 and effectively preventing the deposition of asphalt liquid at the bottom of tank 6.

[0025] To improve the flow rate of the asphalt liquid, the guide tube 8 adopts a hollow structure. A heat transfer oil inlet 3 is arranged horizontally on one side of the guide tube 8, and a heat transfer oil outlet 14 is arranged vertically on the other side. In practical applications, heat transfer oil can be introduced into the guide tube 8 through the inlet 3. During the flow of the heat transfer oil in the guide tube 8, it exchanges heat with the asphalt liquid, further increasing the storage temperature of the asphalt liquid here, thereby enhancing the fluidity of the asphalt liquid.

[0026] Working process: First, the asphalt liquid to be stored is injected into the tank 6 through the asphalt liquid inlets 10 on both sides of the tank 6 until the set storage volume is reached. Then, the external heating equipment is started to heat the heat transfer oil. The heated heat transfer oil enters the jacket 5 through the oil inlet 1 at the bottom of the jacket 5 to exchange heat with the tank 6, keeping the temperature of the asphalt liquid in the tank 6 stable. At the same time, heat transfer oil can be introduced into the guide tube 8 as needed to further increase the temperature of the asphalt liquid at the bottom of the tank 6. Then, the motor 12 is started, which drives the shaft 9 and the agitator 7 to rotate. The agitator 7 stirs the asphalt liquid in the tank 6 to prevent the asphalt liquid from separating and settling. During the stirring process, the asphalt liquid inside the guide tube 8 generates eddies, which promotes the circulation of the asphalt liquid inside the tank 6, further improving the stirring effect. When the stored asphalt liquid needs to be used, the asphalt liquid outlet 2 at the bottom of the tank 6 is opened to discharge the asphalt liquid. During the discharge process, the opening of the outlet 2 can be adjusted according to actual needs to control the discharge flow rate.

[0027] Based on the above structural design and working principle, this asphalt liquid heat preservation and storage device can effectively solve the problem of stratification and sedimentation that occurs during the storage of asphalt liquid. At the same time, it achieves good heat preservation effect through the heat transfer oil circulation system, ensuring the quality and fluidity of the asphalt liquid and meeting the needs of subsequent use.
