Description

Technical Field

[0001] The utility model relates to the field of asphalt processing, in particular to an asphalt tank which is convenient for heating asphalt. Background Art

[0002] Asphalt is a complex, dark-brown mixture of hydrocarbons and their non-metallic derivatives of varying molecular weights. It mostly exists in liquid or semi-solid petroleum form, with a black surface. It is soluble in organic solvents such as carbon disulfide and carbon tetrachloride. It is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material, characterized by its non-conductive, non-absorbent, acid-resistant, alkali-resistant, and corrosion-resistant properties. With the continuous development of the asphalt industry, various polymer-modified asphalts have emerged. Modified asphalt is made by adding modifiers such as SBS, SBR, EVA, and PE to ordinary base asphalt to enhance its thermal stability and crack resistance. This improves the adhesion of asphalt to aggregates and imparts new mechanical properties. The asphalt modification process not only improves its performance but also alters its physical properties. Asphalt viscosity has increased from a maximum of 2000 cSt at 135°C to approximately 3000-4000 cSt at 180°C. This increased viscosity requires higher spreading temperatures.

[0003] An asphalt tank is a device specifically used for heating asphalt. It has the characteristics of fast heating, energy saving, and environmental protection.

[0024] See also Figure 1 、 Figure 3 、 Figure 4 The utility model provides a technical solution: an asphalt tank for facilitating asphalt heating, comprising a plurality of asphalt tank groups arranged side by side and a loading mechanism arranged along the top sides of the plurality of asphalt tank groups, wherein each asphalt tank group comprises a lifting frame 1, a partition 2, a fence 3 and a heating tank module, the lifting frame 1 is a bracket structure with movable legs provided on the bottom side, an angle iron piece 14 provided in the middle, and an angle iron piece 2 15 provided on the top side, the fence 3 encloses the outside of the partition 2, the partition 2 is connected to the angle iron piece 14 in the middle of the lifting frame 1 by bolts, a notch is provided in the middle of the inner side of the partition 2, and the heating tank module can be installed in the notch, the heating tank module comprises a tank shell 4, a motor 5, a support arm 6, a gear ring 7, a gear 8 and a motor 2 (not shown in the figure); one side of the support arm 6 is rotatably installed on the inner side of the notch, and the other side of the support arm 6 is driven by the motor 5, and a mounting hole is provided in the middle of the support arm 6.

[0025] See also Figure 3 In this embodiment, the tank shell 4 can be installed in the middle of the support arm 6. The tank shell 4 is a circular tank structure with an open top and a discharge head at the bottom. The inner cavity of the tank shell 4 is equipped with an electric heating layer (not shown in the figure), and the outer periphery of the tank shell 4 is provided with a ring gear 7. The inner side of the tank shell 4 can be provided with an inner liner to prevent asphalt adhesion. The electric heating layer is located behind the inner liner and can quickly heat the asphalt raw material to a molten state. When the motor 5 rotates, it drives the support arm 6 and the tank shell 4 to deflect. After the asphalt raw material is processed, the entire support arm 6 can be deflected to facilitate the pouring of the asphalt raw material at the bottom of the tank.

[0026] In this embodiment, the rack on the ring gear 7 is positioned downward, and motor 2 is mounted on one side of arm 6. A gear 8 is connected to the end of the motor's shaft and meshes with the ring gear 7. Motor 2 drives gear 8 to mesh with the ring gear 7, causing the tank shell 4 to rotate relative to the arm 6. By driving gear 8 to mesh with the ring gear 7, motor 2 causes the tank shell 4 to deflect relative to the arm 6, thereby enhancing the mixing effect of the molten asphalt feedstock.

[0027] See also Figure 2In this embodiment, the feeding mechanism includes a track 9, a screw 10, a support 11, and a hopper 12. The track 9 is mounted on an angle iron piece 2 15 on the top side of the lifting frame 1. The inner side of the track 9 is rotatably connected to the screw 10. The front end of the screw 10 is driven by a motor 3. The screw 10 is provided with a slide that can slide with the track 9. In actual application, in order to improve the feeding efficiency of the feeding mechanism, a conveyor can be provided outside the feeding mechanism. When the feeding mechanism moves to the feeding side of the track 9, the conveyor can transport the asphalt raw material into the hopper 12. When the feeding mechanism moves out of the feeding side (moves to the asphalt tank group position), the conveyor stops feeding. Only one conveyor is needed to meet the feeding needs of multiple asphalt tank groups.

[0028] In this embodiment, the supporting seat 11 is connected between the two slides, a feeding pipe (not shown) is provided on the bottom side of the supporting seat 11, and a hopper 12 connected to the feeding pipe is mounted on the supporting seat 11.

[0029] In this embodiment, an openable valve plate is provided on the bottom side of the discharge pipe, and the discharge pipe can move along the track 9 with the supporting seat 11 and feed multiple asphalt tank groups.

[0030] In this embodiment, the inner diameter of the mounting hole matches the outer diameter of the discharge pipe 13 , and a valve is provided on the discharge pipe 13 .

[0031] The working principle of the above-mentioned asphalt tank loading and heating and stirring is as follows:

[0032] During operation, the screw 10 drives the support seat 11 to move along the track 9. When it moves to the corresponding asphalt tank group, the valve plate on the bottom side of the discharge pipe opens, and the asphalt raw material in the hopper 12 is discharged from the hopper 12 to the asphalt tank group through the discharge pipe; the asphalt tank group receives the material through the tank shell 4. After the asphalt raw material enters the tank shell 4, the heating layer is used to heat the asphalt raw material. At the same time, the motor 2 can be used to drive the gear 8 to engage the ring gear 7 and rotate the tank shell 4 relative to the support arm 6, and the motor 1 5 can be used to drive the support arm 6 and the tank shell 4 to deflect, so that the asphalt raw material is in a molten and stirred state. After the heating is completed, the device is reset, and the asphalt raw material is discharged using the valve on the discharge pipe 13. In addition, due to the setting of the lifting frame 1, the gap on the lower side of the lifting frame 1 can accommodate a trailer, which can facilitate the transfer of the asphalt raw material.

[0033] It is worth noting that the entire device is controlled by a general control system. Since the equipment matched with the control system is commonly used equipment and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
