Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of asphalt transportation, and particularly relates to an asphalt transportation equipment. BACKGROUND

[0002] Asphalt is an important road construction material. In the process of asphalt transportation, the asphalt will gradually solidify once the temperature decreases and the flowability is poor. Therefore, anti-solidification operation is needed in the transportation process. The traditional asphalt transportation equipment usually adopts a continuous heating mode to keep the asphalt at a high temperature, so as to reduce the probability of solidification of the asphalt in the transportation process. However, since a large amount of asphalt is usually needed for road construction, the asphalt transportation equipment is large in size, the asphalt is difficult to flow and has a short flow path during transportation, and temperature stratification is prone to occur. In particular, in long-distance transportation, the temperature distribution of the asphalt at different layers is uneven and the flowability is poor, the surface layer of the asphalt is prone to local solidification due to fast heat dissipation, and the bottom layer of the asphalt is prone to hardening due to poor flowability, which will seriously affect the normal unloading and use of the asphalt. SUMMARY

[0003] In order to overcome the shortcomings pointed out in the background, the present application provides an asphalt transportation equipment.

[0007] Preferably, the isolation shell is provided with symmetrically distributed flow holes, and a baffle is slidably connected to the isolation shell and is slidably connected to the box body. The baffle is used to block the adjacent symmetrically distributed flow holes, and the box body is fixed with a plurality of electric control push rods, the number of the electric control push rods is the same as the number of the baffles, and the telescopic part of the electric control push rod is fixed to the baffle.

[0008] Preferably, symmetrically distributed guide plates are fixed to the lower side of the isolation plate, and the upper side of the guide plates is located at the corresponding second holes on the upper adjacent isolation plate, and the distance between the symmetrically distributed guide plates gradually decreases from top to bottom.

[0009] Preferably, the shell, the bottom plate and the isolation plate are gradually inclined downward from the position adjacent to the discharge port to the position adjacent to the feed port.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention causes the asphalt in the box to flow by the rotation of the auger, and provides a bottom plate with a first through hole and a second through hole to increase the length of the asphalt circulation flow path, thereby reducing the probability of asphalt solidifying during transportation to ensure the normal unloading and use of asphalt. By providing multiple layers of isolation plates with first holes, second holes and third holes, the flow of asphalt is guided to increase the length of the asphalt flow path. Moreover, during the transportation and use of asphalt, when the height of the asphalt changes, the two flow holes on the isolation shell of the corresponding layer are opened, and the asphalt passes through the new corresponding layer with the first hole, the second hole and the third hole. The isolation plates have one hole, a second hole and a third hole, and then the asphalt passes through the two flow holes of the corresponding layer of isolation shell, so that the asphalt forms a new circulation path, so as to ensure the longest flow path of the asphalt circulation according to the storage amount of the asphalt, thereby ensuring the fluidity of different amounts of asphalt according to the height of the asphalt, so as to reduce the probability of asphalt solidification, and thus ensure the normal use of the asphalt, and use the guide plate, bottom plate and isolation plate to guide the asphalt. When the liquid level of the asphalt is lowered during use, the residual amount of asphalt on the surface of the bottom plate and isolation plate is reduced, thereby reducing the probability of asphalt solidifying on the surface of the bottom plate and isolation plate, reducing the difficulty of cleaning the bottom plate and isolation plate, and thus improving the use efficiency of the device.

[0021] As shown in Figure 3-Figure 5As shown, the box body 1 is fixed with a plurality of isolation plates 7 which are symmetrical left and right and spaced apart up and down, all the isolation plates 7 are located above the corresponding bottom plate 6, the isolation plate 7 is provided with a first hole 701, all the first holes 701 are located above the adjacent first through hole 601, the isolation plate 7 is provided with two second holes 702 which are symmetrically distributed front and back, the first hole 701 is located between the two second holes 702, the isolation plate 7 is provided with a third hole 703, all the third holes 703 are located above the second through hole 602, when the two augers 5 rotate, taking the right side of the upper and lower isolation plate 7 as an example, the upper asphalt passes through all the first holes 701 on the right side and all the second holes 702 on the right side from top to bottom, then the asphalt enters the right side of the first through hole 601, the asphalt flows through the right side of the feed port 401 and is driven by the right side of the auger 5, the asphalt is discharged to the right side of the second through hole 602 through the right side of the discharge port 402, then the asphalt passes through all the third holes 703 on the right side from bottom to top, the asphalt flows upward and circulates again.

[0022] As Figure 3 With Figure 4 As shown, the adjacent two isolation plates 7 are fixed with an isolation shell 8, the isolation shell 8 is located in the middle of the adjacent isolation plate 7, the isolation shell 8 separates the corresponding third hole 703 and the corresponding first hole 701 on the left and right sides respectively, the isolation shell 8 is provided with a heating structure not shown in the figure, all the heating structures are electrically connected with the control terminal.

[0023] As Figure 3-Figure 5 As shown, the isolation shell 8 is provided with two flow holes 801 which are symmetrically distributed left and right, the isolation shell 8 is slidably connected with a blocking frame 9 which is slidably connected with the box body 1, initially, the blocking frame 9 is used to block the adjacent symmetrically distributed flow holes 801, which separates the asphalt on the left and right sides of the isolation shell 8, when the blocking frame 9 moves forward, the blocking frame 9 no longer blocks the adjacent two flow holes 801, so that the asphalt on the left and right sides of the isolation shell 8 can flow through the two flow holes 801 above it, the box body 1 is fixed with a plurality of electric control push rods 10 which are electrically connected with the control terminal, the number of electric control push rods 10 is the same as the number of blocking frames 9, the extension part of the electric control push rod 10 is fixed with the blocking frame 9, the extension part of the electric control push rod 10 is used to drive the blocking frame 9 to move forward and backward.

[0024] The specific working principle is as follows: When the operator needs to use this device to transport asphalt, the asphalt is injected into the box body 1 through the two connecting pipes of the cover body 2. When the box body 1 is filled with asphalt, the box body 1 and the asphalt inside are transported by a vehicle. During the asphalt transportation process, the operator turns on the heating structure and the power part 3 through the control terminal. All heating structures heat the asphalt in the box body 1. The power part 3 drives the two augers 5 to rotate. When the two augers 5 rotate, taking the isolation plates 7 at intervals on the right side as an example, the upper asphalt passes from top to bottom through the first hole 701 and the two second holes 701 of the upper isolation plate 7. The asphalt passes through all the first holes 701 on the right and all the second holes 702 on the right, and enters the first through hole 601 on the right. The asphalt passes through the right feed port 401 and is driven by the right auger 5 to flow. The asphalt is discharged to the second through hole 602 on the right through the right discharge port 402. The asphalt passes through all the third holes 703 on the right from bottom to top. The asphalt flows upward to the upper right isolation plate 7 and circulates again, so that the asphalt circulates in the box body 1, increasing the length of the asphalt flow path, thereby reducing the probability of the asphalt solidifying during transportation to ensure the normal use of the asphalt.

[0025] After the asphalt is transported to the place of use, when the asphalt is needed, the operator connects the pipeline to the two discharge pipes at the bottom of the box body 1 and extracts the asphalt in the box body 1 through the shell 4. When a part of the asphalt in the box body 1 is used, the level of the asphalt in the box body 1 decreases. Taking the asphalt level as low as the upper isolation plate 7 as an example, the upper electric control push rod 10 is turned on by the control terminal, and the telescopic end of the upper electric control push rod 10 drives the adjacent baffle 9 to move forward. The baffle 9 no longer blocks the two adjacent flow holes 801, so that the asphalt on the left and right sides of the upper isolation shell 8 can flow through the two flow holes 801 thereon. During the circulation process, the asphalt no longer passes through the upper isolation plate 7. The asphalt passes through the first hole 701 and the two second holes 702 of the second upper isolation plate 7, and the above steps are repeated for circulation. When the asphalt circulates to the second upper isolation plate 7, the asphalt passes through the two flow holes 801 of the upper isolation shell 8, and finally flows to the first hole 701 and the two second holes 702 of the second upper isolation plate 7, so that the asphalt forms a new circulation path.

[0026] During the transportation and use of asphalt, when the height of asphalt changes, a new circulation path is formed for the asphalt to adjust the longest flow path of the asphalt circulation according to the storage amount of asphalt, thereby ensuring the fluidity of different amounts of asphalt according to the height of the asphalt, reducing the probability of asphalt solidification, and thus ensuring the normal use of asphalt.

[0027] When the asphalt is used up, the operator turns off the power part 3 and the heating structure through the control terminal, and cleans the box body 1 and the parts inside it.

[0028] Example 2

[0029] Based on the above embodiment 1, Figure 2 、 Figure 3 and Figure 5 As shown, two guide plates 11 symmetrically distributed front and back are fixed to the lower side of the isolation plate 7, and the upper side of the guide plate 11 is located at the corresponding second hole 702 on the upper adjacent isolation plate 7. The distance between the symmetrically distributed guide plates 11 gradually decreases from top to bottom. The guide plate 11 is used to guide the asphalt flowing out of the second hole 702 to the first hole 701 of the lower isolation plate 7. The shell 4, the bottom plate 6 and the isolation plate 7 are gradually inclined downward from the adjacent discharge port 402 to the adjacent feed port 401, so that the asphalt accumulated on the upper side of the shell 4, the bottom plate 6 and the isolation plate 7 can flow along the inclined surface, thereby reducing the shell 4. , the probability of asphalt accumulation on the upper surface of the bottom plate 6 and the isolation plate 7, the upper surface of the bottom plate 6 and the upper surface of the isolation plate 7 are gradually inclined downward from the front and rear sides to the middle, which is used to guide the asphalt accumulated on the upper surface of the bottom plate 6 and the upper surface of the isolation plate 7. In the process of using the asphalt, the asphalt is guided by the guide plate 11, the bottom plate 6 and the isolation plate 7. When the asphalt liquid level is lowered, the residual amount of asphalt on the upper surface of the bottom plate 6 and the isolation plate 7 is reduced, thereby reducing the probability of asphalt solidifying on the surface of the bottom plate 6 and the isolation plate 7, reducing the difficulty of cleaning the bottom plate 6 and the isolation plate 7, and thereby improving the use efficiency of the device.

[0030] Example 3

[0031] Based on the above embodiment 2, Figure 6 As shown, the box body 1 is provided with a plurality of insulation chambers 13, all of which are respectively located in different side walls of the box body 1, and the lower part of the insulation chamber 13 is connected to the outside of the box body 1. The cover body 2 is provided with a circulation groove 17 connected to all the insulation chambers 13, and the circulation groove 17 is located above all the insulation chambers 13, so that the hot air in the box body 1 enters all the insulation chambers 13 through the circulation groove 17 to keep the box body 1 warm.

[0032] like Figure 1 、 Figure 6 and Figure 7 As shown, the box body 1 is fixed with the same number of fixing seats 14 as the number of insulation chambers 13, and the fixing seats 14 are rotatably connected with rotating plates 15. The rotating plates 15 are used to seal adjacent insulation chambers 13. A torsion spring 16 is fixed between the rotating plates 15 and the adjacent fixing seats 14. All the fixing seats 14 and all the rotating plates 15 are located at the lower part of the box body 1. After the hot air enters all the insulation chambers 13, the hot air squeezes the gas in the lower part of the insulation chamber 13, causing the rotating plate 15 to rotate, and the torsion spring 16 twists and accumulates force to squeeze out the gas in the lower part of the insulation chamber 13.

[0033] The specific working principle is as follows: During the process of transporting asphalt using this device, in order to prevent the asphalt from solidifying, the asphalt needs to be kept at a high temperature and continuously heated by the heating structure. When the asphalt is heated to generate hot gas, the hot gas in the box 1 enters all the insulation chambers 13 through the circulation grooves 17. The hot gas in the insulation chambers 13 is used to insulate the asphalt in the box 1, thereby saving heating and insulation energy while improving the insulation effect of the box 1 on the asphalt.

[0034] When the heat in the box body 1 increases, resulting in a high-pressure environment in the box body 1, the hot air in the box body 1 enters all the insulation chambers 13 through the circulation grooves 17, and the gas in the insulation chamber 13 is squeezed to the rotating plate 15. The gas squeezes the rotating plate 15 to rotate, causing the torsion spring 16 to twist, and the gas in the insulation chamber 13 is discharged, thereby relieving the pressure inside the box body 1, so as to reduce the probability of asphalt leakage during discharge due to the high pressure inside the box body 1, or even the probability of pipeline bursting, thereby ensuring the safety of asphalt discharge.

[0035] When the box body 1 is no longer in a high-pressure environment, the torsion spring 16 is reset, causing the rotating plate 15 to reset, and the rotating plate 15 blocks the heat preservation chamber 13. When the device is finished using, the operator turns off the power part 3 and the heating structure through the control terminal, and cleans the box body 1 and its internal parts.

These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention.
