Description

Technical Field

[0001] This utility model relates to the field of modified asphalt storage technology, specifically to a modified asphalt time-delay tank. Background Technology

[0002] Due to its special material properties, modified asphalt is very easy to solidify and harden at room temperature. Therefore, it needs to be continuously heated and stirred during storage to maintain its fluid state.

[0003] Currently, most mainstream storage equipment in the industry uses heating pipes wrapped around the outside of the tank and agitator blades installed inside to achieve the above functions. However, this traditional design has significant drawbacks: the heat from the external heating pipes is mainly conducted along the tank wall, causing the modified asphalt in the central area of ​​the tank to be difficult to reach an effective heating temperature due to its distance from the heat source; at the same time, due to the structural limitations and fluid dynamics characteristics of the agitator blades, the asphalt inside the tank can only be locally agitated, failing to achieve efficient overall circulation, ultimately affecting the storage time of the modified asphalt. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a modified asphalt time-delay tank to solve the problem of poor circulation of modified asphalt in the prior art, which affects storage time.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a modified asphalt delay tank, comprising: a tank body, the tank body including an inner tank body and an outer tank body sleeved on the outer body of the inner tank body; the inner tank body is provided with an inner cylinder, the inner cylinder dividing the inner tank body into a first cavity and a second cavity, and the inner tank body is also provided with a mixing mechanism; wherein, the mixing mechanism includes a spiral lifting part fixed on a rotating shaft, the spiral lifting part being disposed in the first cavity and forming a flow channel within the inner tank body.

[0006] Optionally, a heating chamber is formed between the inner tank and the outer tank, and a heating element capable of heating the inner tank is provided in the heating chamber.

[0007] Optionally, the rotating shaft is driven by a motor fixed to the outer tank body, and the two ends of the spiral lifting part are respectively provided with a dispersing paddle and a scraper fixed to the rotating shaft. The dispersing paddle is located on the side of the spiral lifting part closer to the motor, and the scraper is used in conjunction with the inner sidewall of the inner tank body.

[0008] Optionally, the inner cylinder is vertically continuous, and its two continuous surfaces form a first gap and a second gap with the inner wall of the inner tank, respectively. The dispersing paddle is located in the first gap, and the scraper is located in the second gap.

[0009] Optionally, the inner cylinder has a narrow opening near the first gap and a wide opening near the second gap, the narrow opening extending toward the wide opening and forming a third slope.

[0010] Optionally, the spiral lifting section has gradually narrowing spiral blades, with the wider spiral blades of the spiral lifting section near the wide end of the inner cylinder and the narrower spiral blades of the spiral lifting section near the narrow end of the inner cylinder.

[0011] Optionally, the mixing mechanism further includes several flexible parts, one end of which is fixed to the scraper, and the other end of which is connected to the outer wall end face of the inner cylinder via a bearing.

[0012] Optionally, the flexible part is a chain or a wire rope.

[0013] Optionally, both the outer tank and the inner tank are provided with a first inclined surface on the side near the scraper, and the scraper is provided with a second inclined surface corresponding to the first inclined surface.

[0014] Optionally, the inner cylinder is suspended inside the inner tank by a hanger.

[0015] The beneficial effects of this utility model are as follows: This invention utilizes an inner cylinder and a mixing mechanism to create a flow channel within the inner tank, allowing modified asphalt to flow from the first cavity to the second cavity and circulate sequentially. This transports the modified asphalt located in the middle of the inner tank to the tank wall, forming a circulation. This improves upon the problem of uneven heating of the modified asphalt in the middle of the inner tank, which easily leads to clumping.

[0016] The inner cylinder of this invention is designed with a smaller upper section and a larger lower section, and the spiral blades of the spiral lifting section are also designed with a smaller upper section and a larger lower section. This concentrates the high thrust generated by the larger diameter at the lower end into the bottom area of ​​the tank where materials are most difficult to transport, while the smaller diameter at the upper end reduces the axial load at the end of the spiral shaft, reduces wear on the bearings and drive unit, and extends the service life of the equipment.

[0017] In addition, this utility model is designed with a scraper. When the scraper rotates with the rotating shaft, it can scrape the inner wall of the inner tank, causing the modified asphalt adhering to it to fall off, thus avoiding the problem of difficult cleaning caused by adhesion due to long-term contact.

[0018] Finally, this invention also incorporates a flexible section that rotates within the inner tank following the rotation of the scraper, thereby breaking up the settling of the modified asphalt within the tank, reducing localized solidification, and enhancing the circulation effect of the modified asphalt within the tank.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As mentioned earlier, most mainstream storage devices in the industry currently use heating pipes wrapped around the outside of the tank and stirring blades installed inside to achieve the above functions. However, this traditional design has significant drawbacks: the heat from the external heating pipes is mainly conducted along the tank wall, causing the modified asphalt in the central area of ​​the tank to be difficult to reach an effective heating temperature due to its distance from the heat source; at the same time, due to the structural limitations and fluid dynamics characteristics of the stirring blades, the asphalt inside the tank can only be locally agitated, failing to achieve efficient overall circulation, ultimately affecting the storage time of the modified asphalt.

[0030] In view of this, the present invention provides a modified asphalt delay tank, which effectively solves the above problems. The present invention solves the problem in the following way.

[0031] Example 1: Please refer to the instruction manual appendix. Figures 1 to 7 As shown in the figure, this embodiment provides a modified asphalt time-delay tank for extending the storage of modified asphalt. The tank includes a tank body 1, an inner cylinder 2, and a mixing mechanism. The tank body 1 comprises an inner tank body 12 and an outer tank body 11. A heating chamber is formed between the inner tank body 12 and the outer tank body 11. A heating element 14 (e.g., an electric heating wire / tube) is provided in the heating chamber to heat the inner tank body 12. The heating element 14 generates heat when energized. The inner tank body 12 receives the heat, its temperature rises, and the heat is conducted to the modified asphalt stored within the inner tank body 12.

[0032] As shown in the attached figure Figure 2 As shown, in this embodiment, the inner cylinder 2 is suspended inside the inner tank 12 by a hanger 23. Its top has a first gap 25 from the top wall of the inner tank 12, and its bottom has a second gap 26 from the bottom wall of the inner tank 12. The inner cylinder 2 is arranged vertically through-hole, thus dividing the internal space of the inner tank 12 into a first cavity 24 and a second cavity 121, where the first cavity 24 is the internal space of the inner cylinder 2.

[0033] Inside the inner cylinder 2, the mixing mechanism includes a rotating shaft 3 and a spiral lifting part 32 fixed on the rotating shaft 3. The rotating shaft 3 is driven by a motor 5 (the motor 5 is located outside the tank 1 and fixed to the outer tank 11) to rotate the spiral lifting part 32. The spiral lifting part 32 has spirally rising blades. When it rotates once, it lifts the modified asphalt carried on the spiral blades by a distance of one pitch, thereby realizing the movement of the modified asphalt inside the inner cylinder 2 (it should be noted that when adding the modified asphalt to be stored into the inner tank 12, the material storage height should be lower than the top surface of the inner cylinder 2). Ultimately, the modified asphalt enters the interior of the first cavity 24 from the second gap 26 below the inner cylinder 2, and moves from the first gap 25 to the second cavity 121, forming as follows. Figure 7 The loop indicated by the dashed arrow.

[0034] That is, a first inclined surface 13 is provided at the bottom of the outer tank 11 and the inner tank 12. When some modified asphalt enters the first cavity 24 from the second gap 26, a corresponding space is created. This space is filled by the modified asphalt located on the inner wall of the inner tank 12 sliding down the first inclined surface 13. At the same time, after the modified asphalt comes out from the first gap 25, it will move along the accumulation to the inner wall of the inner tank 12. This cycle repeats, allowing the modified asphalt located in the middle of the inner tank 12 to move to the outside, thereby ensuring that all parts of the modified asphalt in the tank 1 can be heated by the heating part 14, ultimately achieving uniform internal heating.

[0035] Example 2: Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 2 , Figure 3 , Figure 6 As shown, in this second embodiment, the two ends of the spiral lifting section 32 are respectively provided with a dispersing paddle 31 and a scraper 33 fixed on the rotating shaft 3. The dispersing paddle 31 is located in the first gap 25, and the scraper 33 is located in the second gap 26. The dispersing paddle 31 has an inclined paddle surface, which can generate a radial pushing flow when it rotates, thereby continuously pushing the modified asphalt coming out of the inner cylinder 2 to the inner wall of the inner tank 12, thereby accelerating the circulation.

[0036] Meanwhile, the scraper 33 is L-shaped and has a second inclined surface 331, which allows it to fit into the inner side wall and bottom wall of the inner tank 12. The scraper 33 is a certain distance away from the inner wall of the inner tank 12. When it rotates with the rotating shaft 3, it can scrape the modified asphalt remaining on the inner wall of the inner tank 12, avoiding the phenomenon of modified asphalt clumping on the inner wall for a long time, which makes it difficult to clean.

[0037] Finally, the mixing mechanism also includes several flexible parts 4. One end of each flexible part 4 is fixed to the scraper 33, and the other end is connected to the outer wall end face of the inner cylinder 2 via a bearing. The flexible parts 4 are chains or wire ropes. When the scraper 33 rotates with the rotating shaft 3, the flexible parts 4 continuously rotate and agitate the modified asphalt stored inside the inner tank 12. This generates shear forces in different directions, which can effectively act on the modified asphalt in the middle of the inner tank 12, thereby preventing it from sticking together and clumping when accumulating.

[0038] Example 3: Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 3 , Figure 6As shown, in this third embodiment, the inner cylinder 2 has a narrow opening 21 near the first gap 25 (i.e., Figure 6 The narrow opening 21 extends toward the wide opening 22 (i.e., a1) near the second gap 26 and forms the third slope 27.

[0039] Correspondingly, the spiral lifting section 32 has gradually narrowing spiral blades, and the spiral lifting section 32 has wider spiral blades (such as...). Figure 6 (a2) is near the wide opening 22 end of the inner cylinder 2, and (b2) is near the narrow opening 21 end of the spiral lifting part 32.

[0040] Since a1 is greater than b1 and a2 is greater than b2, the diameter of the blades in the spiral lifting section 32 at the feed end of the inner cylinder 2 is larger. This results in stronger centrifugal force and thrust generated during blade rotation, effectively gripping the viscous asphalt adhering to the bottom of the tank. This prevents the spiral from spinning idly or slipping due to high friction. Furthermore, the high thrust generated by the larger diameter is concentrated in the most difficult-to-transport material accumulation area at the bottom of the tank, thus improving the lifting efficiency of the spiral lifting section 32 for modified asphalt. Simultaneously, at the discharge end of the inner cylinder 2, the diameter of the blades in the spiral lifting section 32 is smaller, reducing the blade linear velocity and slowing down the conveying speed of the modified asphalt. The smaller diameter also reduces the axial load on the end of the spiral lifting section 32 shaft, reducing wear and making it suitable for long-term low-speed operation, thereby extending its service life.

[0041] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: This invention, through the inner cylinder 2 and the mixing mechanism, forms a flow channel within the inner tank 12, allowing modified asphalt to flow from the first cavity 24 to the second cavity 121, and circulate sequentially. This transports the modified asphalt located in the middle of the inner tank 12 to the tank wall, forming a circulation. This improves the problem of uneven heating of the modified asphalt in the middle of the inner tank 12, which easily leads to clumping.

[0042] The inner cylinder 2 of this invention is designed with a smaller upper diameter and a larger lower diameter, and the spiral blades of the spiral lifting part 32 are also designed with a smaller upper diameter and a larger lower diameter. This concentrates the high thrust generated by the large diameter at the lower end into the bottom area of ​​the tank where the material is most difficult to transport, while the small diameter at the upper end reduces the axial load at the end of the spiral shaft, reduces the wear of the bearings and drive device, and extends the service life of the equipment.

[0043] In addition, this utility model also includes a scraper 33. When the scraper 33 rotates with the rotating shaft 3, it can scrape the inner wall of the inner tank 12, causing the modified asphalt adhering to it to fall off, thus avoiding the problem of difficult cleaning caused by adhesion due to long-term contact.

[0044] Finally, this utility model also includes a flexible part 4, which rotates within the inner tank 12 following the rotation of the scraper 33, thereby breaking the sedimentation of the modified asphalt in the tank, reducing local solidification, and helping to improve the circulation effect of the modified asphalt in the tank.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
