Description

Technical Field

[0001] The present invention belongs to the technical field of construction machinery, and in particular relates to a hot asphalt transportation and storage device with an anti-blocking function. Background Art

[0002] A hot asphalt storage device is a device specifically used for storing and transporting hot asphalt, usually including components such as a storage tank, a heating device, a conveying system, etc. Its main function is to maintain the temperature and fluidity of hot asphalt during transportation, storage, and construction, ensuring that the asphalt can maintain an appropriate viscosity within the required temperature range for smooth application during paving and use. During the actual process of paving roads, the storage device is often placed on a vehicle body and moves with the vehicle body to achieve asphalt paving of the road.

[0003] Hot asphalt storage devices are usually designed to withstand high-temperature environments and are equipped with effective heating devices to maintain the temperature of the asphalt. The inner walls of these devices usually use high-temperature-resistant materials and are provided with heat insulation layers to avoid heat dissipation and reduce energy consumption. In addition, these devices are usually equipped with stirring devices that can evenly mix some solid materials (such as waste rubber) with the recycled hot asphalt, thereby improving the performance of the asphalt. For example, a hot asphalt transportation and storage device for highway construction disclosed in Chinese Publication No. CN213709046U can stir the asphalt through a stirring rod. However, the above-mentioned hot asphalt transportation and storage device still has the following technical problems during use: During the storage process, the storage tank often remains stationary in one place. Although the hot asphalt can be stirred during this process, the storage tank itself cannot be shaken, resulting in the hot asphalt in the storage tank still being stratified under the action of stirring, resulting in unstable quality of the hot asphalt and affecting its subsequent use effect; During the storage process, the stirring rate cannot be adjusted according to the temperature of the asphalt. In the initial stage and subsequent stable stage of asphalt heating, the overall temperature of the asphalt is different. This temperature change will directly affect the fluidity of the asphalt and the mixing effect with other components. In the initial stage, the temperature of the asphalt is relatively low and its fluidity is relatively low. If the stirring rate of the asphalt is insufficient, local uneven stirring will occur, and the possibility of asphalt blockage will increase at the positions with poor stirring effect. In the subsequent stable stage, the temperature of the asphalt is relatively high and its fluidity is relatively high. At this time, if the stirring rate of the asphalt is too fast, unnecessary disturbances will occur, further generating bubbles and reducing the use performance of the asphalt. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems proposed in the above background art, and provide a hot asphalt transportation and storage device with an anti-blocking function that can continuously shake the storage tank, and the hot asphalt in the storage tank is more uniform under the action of shaking.

[0007] Preferably, a limiting block is fixedly connected to the side of the stirring shaft away from the rotating rod.

[0008] Preferably, a driving mechanism is provided at the upper end of the base for driving the circumferential shaking mechanism and the self-cleaning stirring mechanism to operate synchronously while avoiding movement interference. The driving mechanism includes a driving motor fixedly connected to the upper end of the base. A first gear and a second gear are fixedly connected to the output end of the driving motor. A first toothed ring is fixedly connected to the inner wall of the driving ring plate. The first toothed ring meshes with the first gear.

A transmission box is fixedly connected to the upper end of the second toothed ring. Through holes are provided at both the upper and lower ends of the transmission box. The bottom end of the rotating rod passes through the bottom wall of the storage tank and the through hole and extends below the transmission box. A transmission ring plate is fixedly connected to the rotating rod. The transmission ring plate is located inside the transmission box. A telescopic sealing ring is arranged between the rotating rod and the through hole.

[0009] Preferably, the radius of the second gear is greater than the radius of the second toothed ring, and the second gear is an incomplete gear.

[0010] Preferably, a speed control mechanism is provided inside the rotating rod for adjusting the stirring speed of the asphalt according to the temperature of the asphalt. The speed control mechanism includes a control cavity opened inside the rotating rod. The control cavity is filled with a thermo - expansion and contraction medium. A piston block is hermetically and slidably connected at a position above the thermo - expansion and contraction medium in the control cavity. A pressure sensor is provided on the inner top wall of the control cavity. A second spring is provided between the piston block and the pressure sensor.

[0011] Preferably, an amplitude control mechanism is provided in each stirring shaft for adjusting the stirring amplitude of the asphalt according to the temperature of the asphalt. The amplitude control mechanism includes a chute opened inside the stirring shaft. An extension shaft is hermetically and slidably connected in the chute.

[0012] Preferably, the pressure sensor is electrically connected to the electrorheological fluid, the first electromagnet, and the second electromagnet.

[0013] Compared with the existing technology, the advantages of the present hot asphalt transportation and storage device with anti - blocking function are as follows: By setting the circumferential shaking mechanism, during the storage process, by driving the rotation of the driving ring plate, the guide wheels move in a circular motion along the annular guide plate and the guide groove. When the guide wheels are at positions on the annular guide plate other than the guide groove, one side of the storage tank tilts up. When the guide wheels are in the guide groove, the storage tank returns to the initial position, enabling the storage tank to shake continuously. The hot asphalt in the storage tank is more uniform under the action of shaking, avoiding the stratification phenomenon, improving the overall quality of the asphalt, and ensuring the subsequent use effect.

[0014] By setting the self - cleaning stirring mechanism, during the storage process, the rotating rod is driven to rotate periodically. When the stirring assembly rotates, the weight cleaning ring on the stirring shaft moves away from the rotating rod under the action of centrifugal force. When the stirring assembly does not rotate, the weight cleaning ring on the stirring shaft approaches the rotating rod under the action of gravity. Through the reciprocating movement of the weight cleaning ring, the stirring shaft can be continuously cleaned during the stirring process, preventing asphalt from adhering to the stirring shaft, and thus ensuring the stirring effect of the stirring shaft on the asphalt.

[0015] In the present invention, by providing a driving mechanism, during the use process, the driving motor can drive the first gear and the second gear to rotate. The first gear drives the driving ring plate to rotate through the first toothed ring, and the second gear can periodically drive the second toothed ring to rotate, further driving the rotating rod to rotate periodically, so that the self-cleaning stirring mechanism starts to work. Only one driving source needs to be set to realize the overall operation of the device, saving energy and improving work efficiency at the same time.

[0016] In the present invention, by providing a speed control mechanism, during the storage process, the temperature of the asphalt will be transmitted to the thermal expansion and contraction medium in the control cavity through the rod body of the rotating rod, further controlling the compression degree of the second spring by the piston block, and thus realizing the adjustment of the viscosity of the electrorheological fluid through the pressure data fed back by the pressure sensor, realizing the adjustment of the transmission efficiency between the electrorheological fluid in the transmission box and the transmission ring plate, and thus adjusting the stirring speed of the asphalt according to its temperature. In the initial stage of heating the asphalt, the rotation speeds of the rotating rod and the stirring shaft are relatively large, ensuring uniform stirring of the asphalt and avoiding blockage of the asphalt in the storage tank due to uneven stirring. In the subsequent stable stage of heating the asphalt, the rotation speeds of the rotating rod and the stirring shaft are relatively small, avoiding unnecessary disturbance caused by over-stirring the asphalt and preventing the generation of bubbles.

[0017] In the present invention, by providing an amplitude control mechanism, during the storage process, the stirring amplitude can also be adjusted through the pressure data fed back by the pressure sensor. In the initial stage of heating, the magnetic repulsion force between the first electromagnet and the second electromagnet is increased, so that the stirring range covered by the stirring shaft and the extension shaft is wider, promoting the mixing of the asphalt and other components. In the subsequent stable stage of heating, the stirring range covered by the stirring shaft and the extension shaft is smaller, further reducing unnecessary disturbance during the stirring process and effectively improving the quality and performance of the asphalt.

Specific implementation mode

[0020] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] Embodiment: Refer to Figures 1 to 7 , a hot asphalt transportation and storage device with anti-blocking function, comprising: Base 1, in actual use, the base 1 is fixedly connected to the vehicle body, an annular mounting plate 11 is fixedly connected to the upper end of the base 1, a storage tank 12 is arranged inside the annular mounting plate 11, and an electric heating plate 13 is fixedly connected to the inner wall of the storage tank 12; Specifically, a feed pipe is fixedly connected to the upper end of the storage tank 12, a discharge port is opened at the lower end of the storage tank 12, one-way valves are arranged in both the feed pipe and the discharge port. When storing asphalt, the one-way valve in the feed pipe is opened, and the one-way valve in the discharge port is closed. Asphalt and some waste solid materials (such as waste rubber, using recycled waste rubber and asphalt can improve the elasticity and wear resistance of asphalt and increase its service life) are transported into the storage tank 12 through the feed pipe. When using asphalt, a separate discharge pipe is docked and installed on the discharge port, and then the one-way valve in the discharge port is opened to realize the transportation and use of asphalt.

[0022] The circumferential shaking mechanism 2 is used to lift the storage tank 12 from various positions to maintain the fluidity of the asphalt in the storage tank 12. The circumferential shaking mechanism 2 includes an annular mounting block 21 fixedly connected to the top end of the annular mounting plate 11. An installation groove 22 is formed in the inner wall of the annular mounting block 21. An annular limiting plate 23 is fixedly connected to the circumferential side wall of the storage tank 12. The annular limiting plate 23 is placed in the installation groove 22. A plurality of first springs 24 distributed in a circumferential array are arranged between the circumferential side wall of the storage tank 12 and the inner wall of the annular mounting plate 11. An annular guide plate 25 is fixedly connected to the circumferential side wall of the storage tank 12. A plurality of guide grooves 26 distributed in a circumferential array are formed at the lower end of the annular guide plate 25. A driving ring plate 27 is rotatably connected to the upper end of the base 1. An extension block 28 is fixedly connected to the outer wall of the driving ring plate 27. The upper end of the extension block 28 is hinged with a guide wheel 29 through a hinge seat. The guide wheel 29 contacts and rolls with the annular guide plate 25 and the guide grooves 26. Specifically, the annular limiting plate 23 is always located in the installation groove 22, which can support the storage tank 12 while avoiding affecting the shaking of the storage tank 12.

[0023] Aiming at the problem in the prior art that the storage tank itself cannot be shaken, resulting in the stratification of the hot asphalt in the storage tank 12 under the stirring action, the present invention solves this problem by setting the circumferential shaking mechanism 2. During the storage process, by rotating the driving ring plate 27, the extension block 28 can be driven to perform a circular motion, so that the guide wheel 29 moves along the annular guide plate 25 and the guide grooves 26 in a circular motion. When the guide wheel 29 is at a position on the annular guide plate 25 other than the guide grooves 26, one side of the annular guide plate 25 and the storage tank 12 is pushed by the guide wheel 29, so that one side of the storage tank 12 is lifted. When the guide wheel 29 is in the guide grooves 26, the storage tank 12 returns to its initial position under the action of gravity and the elastic force of the circumferential first spring 24, so that the storage tank 12 can be periodically lifted upward from multiple positions, causing the storage tank 12 to shake continuously. The hot asphalt in the storage tank 12 is more uniform under the action of shaking, avoiding stratification, improving the overall quality of the asphalt, and ensuring the subsequent use effect.

[0024] The self-cleaning stirring mechanism 3 is used to stir the asphalt in the storage tank 12. The self-cleaning stirring mechanism 3 includes a rotating rod 31 rotatably connected through the inner bottom wall of the storage tank 12. A plurality of groups of stirring components 32 distributed in a linear array are fixedly connected to the rotating rod 31. Each group of stirring components 32 includes stirring shafts 321 distributed in a circumferential array on the circumferential side of the rotating rod 31. The stirring shafts 321 are inclined upward, and a weight cleaning ring 322 is hermetically and slidably sleeved on the stirring shafts 321.

[0025] Specifically, a limiting block 323 is fixedly connected to the side of the stirring shaft 321 away from the rotating rod 31. The arrangement of the limiting block 323 enables the weight cleaning ring 322 to not detach from the stirring shaft 321 when reciprocating along the stirring shaft 321, ensuring the self-cleaning work of the stirring shaft 321.

[0026] It is worth mentioning that by providing the self-cleaning stirring mechanism 3, during storage, the driving rotating rod 31 periodically rotates, thereby driving the multiple groups of stirring components 32 to periodically perform circular motion to stir the asphalt in the storage tank 12. When the stirring component 32 rotates, the weight cleaning ring 322 on the stirring shaft 321 moves away from the rotating rod 31 under the action of centrifugal force. When the stirring component 32 does not rotate, the weight cleaning ring 322 on the stirring shaft 321 approaches the rotating rod 31 under the action of gravity. Through the reciprocating movement of the weight cleaning ring 322, the stirring shaft 321 can be continuously cleaned during the stirring process, preventing asphalt from adhering to the stirring shaft 321, thereby ensuring the stirring effect of the stirring shaft 321 on the asphalt.

[0027] A driving mechanism 4 is provided at the upper end of the base 1 for driving the circumferential shaking mechanism 2 and the self-cleaning stirring mechanism 3 to operate synchronously while avoiding movement interference. The driving mechanism 4 includes a driving motor 41 fixedly connected to the upper end of the base 1. A first gear 42 and a second gear 43 are fixedly connected to the output end of the driving motor 41. A first toothed ring 44 is fixedly connected to the inner wall of the driving ring plate 27. The first toothed ring 44 meshes with the first gear 42. A second toothed ring 45 is rotatably connected to the upper end of the base 1. The second toothed ring 45 meshes with the second gear 43. A transmission box 46 is fixedly connected to the upper end of the second toothed ring 45. Through holes 47 are provided at both the upper and lower ends of the transmission box 46. The bottom end of the rotating rod 31 passes through the bottom wall of the storage tank 12 and the through hole 47 and extends below the transmission box 46. A transmission ring plate 48 is fixedly connected to the rotating rod 31. The transmission ring plate 48 is located inside the transmission box 46. A telescopic sealing ring 49 is provided between the rotating rod 31 and the through hole 47.

[0028] Specifically, the radius of the second gear 43 is larger than the radius of the second toothed ring 45, and the second gear 43 is an incomplete gear. Therefore, when the driving motor 41 drives the second gear 43 to rotate, it can drive the second toothed ring 45 to rotate at a relatively faster speed, ensuring that regardless of whether the subsequent transmission box 46 drives the rotating rod 31 to rotate at a relatively fast transmission efficiency or a relatively slow transmission efficiency, the weight cleaning ring 322 can move away from the rotating rod 31 under the action of centrifugal force.

[0029] It should be noted that in the present invention, by providing the driving mechanism 4, during the use process, the driving motor 41 can drive the first gear 42 and the second gear 43 to rotate. The first gear 42 drives the driving ring plate 27 to rotate through the first toothed ring 44, causing the circumferential shaking mechanism 2 to start working. Since the second gear 43 is an incomplete gear, the second gear 43 can periodically drive the second toothed ring 45 to rotate. The second toothed ring 45 further drives the rotating rod 31 to rotate periodically through the transmission box 46 and the transmission ring plate 48, causing the self-cleaning stirring mechanism 3 to start working. Only by setting one driving source can the overall operation of the device be realized, saving energy while improving work efficiency.

[0030] A rate control mechanism 5 is provided inside the rotating rod 31 for adjusting the stirring rate of asphalt according to the temperature of the asphalt. The rate control mechanism 5 includes a control cavity 51 opened inside the rotating rod 31. The control cavity 51 is filled with a thermo - expansion and contraction medium. A piston block 52 is hermetically and slidably connected at a position above the thermo - expansion and contraction medium inside the control cavity 51. A pressure sensor 53 is provided on the inner top wall of the control cavity 51. A second spring 54 is provided between the piston block 52 and the pressure sensor 53. A liquid storage space is formed between the transmission box 46 and the expansion seal ring 49, and the liquid storage space is filled with an electrorheological fluid.

[0031] In view of the problem in the prior art that the stirring rate of asphalt cannot be adjusted according to its temperature, during the initial heating stage and the subsequent stable stage of asphalt heating, the overall temperature of the asphalt is different. This temperature change will directly affect the fluidity of the asphalt and the mixing effect with other components, resulting in problems such as uneven stirring or over - stirring. In the present invention, by providing the rate control mechanism 5, during the storage process, the temperature of the asphalt will be transmitted to the thermo - expansion and contraction medium inside the control cavity 51 through the rod body of the rotating rod 31, further controlling the compression degree of the second spring 54 by the piston block 52, so as to adjust the viscosity of the electrorheological fluid through the pressure data feedback by the pressure sensor 53, and realize the adjustment of the transmission efficiency between the electrorheological fluid inside the transmission box 46 and the transmission ring plate 48, thereby adjusting the stirring rate of asphalt according to its temperature. The specific adjustment process is as follows: In the initial stage of asphalt heating, the temperature of the asphalt is relatively low, and its fluidity is relatively low. At this time, the expansion degree of the thermal expansion and contraction medium is relatively small, the compression degree of the second spring 54 by the piston block 52 is small, the pressure applied by the second spring 54 on the pressure sensor 53 is small, and the pressure sensor 53 adjusts the power supply voltage of the circuit where the electrorheological fluid is located to be relatively large according to the pressure data, so that the viscosity of the electrorheological fluid is in a relatively large state, making the shear stress between the transmission box 46 and the electrorheological fluid and the shear stress between the electrorheological fluid and the transmission ring plate 48 relatively large, so that the transmission efficiency between the transmission box 46 and the transmission ring plate 48 is relatively large. When the transmission box 46 rotates, the rotation speeds of the rotating rod 31 and the stirring shaft 321 are relatively large, ensuring uniform stirring of the asphalt and avoiding blockage of the asphalt in the storage tank 12 due to uneven stirring; In the subsequent stable stage of asphalt heating, the temperature of the asphalt is relatively high, and its fluidity is relatively high. At this time, the expansion degree of the thermal expansion and contraction medium is relatively large, the compression degree of the second spring 54 by the piston block 52 is large, the pressure sensor 53 adjusts the power supply voltage of the circuit where the electrorheological fluid is located to be relatively small according to the pressure data, making the transmission efficiency between the transmission box 46 and the transmission ring plate 48 relatively small. When the transmission box 46 rotates, the rotation speeds of the rotating rod 31 and the stirring shaft 321 are relatively small, avoiding unnecessary disturbance caused by over-stirring of the asphalt, preventing the generation of bubbles, and improving the service performance of the asphalt.

[0032] Each stirring shaft 321 is provided with an amplitude control mechanism 6 for adjusting the stirring amplitude of the asphalt according to the temperature of the asphalt. The amplitude control mechanism 6 includes a chute 61 opened inside the stirring shaft 321. An extension shaft 62 is hermetically and slidably connected in the chute 61. A first electromagnet 63 is provided on the inner wall of the chute 61. A second electromagnet 64 is provided at one end of the extension shaft 62 close to the first electromagnet 63. When the first electromagnet 63 and the second electromagnet 64 are energized, the same poles repel each other. A third spring 65 is provided between the extension shaft 62 and the inner wall of the chute 61. One end of the extension shaft 62 away from the second electromagnet 64 extends outside the stirring shaft 321.

[0033] Specifically, the pressure sensor 53 is electrically connected to the electrorheological fluid, the first electromagnet 63, and the second electromagnet 64.

[0034] Specifically, during the shaking process of the storage tank 12, the stirring shaft 321 is always in an upwardly inclined state, avoiding the change of the stirring shaft 321 from an upwardly inclined state to a downwardly inclined state, and preventing the self-gravity of the stirring shaft 321 from having a greater impact on the resultant force among the first electromagnet 63, the second electromagnet 64, and the third spring 65.

[0035] Specifically, the thermal expansion and contraction medium filled in the control chamber 51 can adopt methyl silicone oil, which has good chemical stability, a relatively low freezing point, and a relatively high boiling point; the liquid storage space is filled with an electrorheological fluid based on barium titanate nanoparticles. In the range of an electric field strength of 0 - 5 kV / mm, the initial viscosity of this electrorheological fluid is approximately 50 mPa·s, and when the electric field strength reaches 5 kV / mm, the viscosity can increase to about 500 mPa·s.

[0036] Specifically, a heat conduction acceleration structure can be additionally provided inside the rotating rod 31, specifically: a highly heat - conductive metal sheet is arranged on the inner wall of the control chamber 51, and this metal sheet closely adheres to the inner wall of the rotating rod 31, which can quickly transfer the heat of the asphalt to the methyl silicone oil, reducing the time delay of heat transfer. At the same time, the pressure sensor 53 and the control circuit are upgraded, adopting a pressure sensor 53 with high - speed response and a control chip with a faster operation speed, shortening the time for pressure data processing and signal transmission, ensuring that the electrorheological fluid, the first electromagnet 63, and the second electromagnet 64 can respond more promptly to the change in asphalt temperature and adjust the stirring rate and stirring amplitude.

[0037] In addition, by setting the amplitude control mechanism 6, during the storage process, the stirring amplitude can also be adjusted according to the pressure data feedback by the pressure sensor 53. In the initial stage of heating, when the asphalt temperature is relatively low, the pressure on the pressure sensor 53 is relatively small, and the current in the circuits where the first electromagnet 63 and the second electromagnet 64 are located is controlled to increase, so that the magnetic repulsion force between the first electromagnet 63 and the second electromagnet 64 increases, making the extension shaft 62 extend more from the stirring shaft 321, so that the stirring range covered by the stirring shaft 321 and the extension shaft 62 is wider, promoting the mixing of asphalt and other components and ensuring that there will be no problem of insufficient local stirring. In the subsequent stable stage of heating, when the asphalt temperature is relatively high, the pressure on the pressure sensor 53 is relatively large, and the current in the circuits where the first electromagnet 63 and the second electromagnet 64 are located is controlled to decrease, the magnetic repulsion force decreases, making the extension shaft 62 extend less from the stirring shaft 321, and the covered stirring range is smaller, further reducing unnecessary disturbances during the stirring process and effectively improving the quality and performance of the asphalt.

[0038] The functional principle of the present invention can be elaborated through the following operation mode: Start the driving motor 41 to drive the first gear 42 and the second gear 43 to rotate. The first gear 42 drives the driving ring plate 27 to rotate through the first toothed ring 44. Since the second gear 43 is an incomplete gear, the second gear 43 can periodically drive the second toothed ring 45 to rotate, and the second toothed ring 45 further periodically drives the rotating rod 31 to rotate through the transmission box 46 and the transmission ring plate 48; When driving the driving ring plate 27 to rotate, it drives the extension block 28 to perform a circular motion, causing the guide wheel 29 to perform a circular motion along the annular guide plate 25 and the guide groove 26. When the guide wheel 29 is at a position on the annular guide plate 25 other than the guide groove 26, the annular guide plate 25 and one side of the storage tank 12 are pushed by the guide wheel 29, causing one side of the storage tank 12 to tilt up. When the guide wheel 29 is in the guide groove 26, the storage tank 12 returns to its initial position, causing the storage tank 12 to periodically tilt up from multiple positions, so that the storage tank 12 can continuously shake; When the rotating rod 31 rotates periodically, it stirs the asphalt in the storage tank 12. When the stirring assembly 32 rotates, the weight cleaning ring 322 on the stirring shaft 321 moves away from the rotating rod 31 under the action of centrifugal force. When the stirring assembly 32 does not rotate, the weight cleaning ring 322 on the stirring shaft 321 approaches the rotating rod 31 under the action of gravity, and continuously cleans the stirring shaft 321 during the stirring process; During the storage process, the temperature of the asphalt will be transmitted through the rod body of the rotating rod 31 to the thermal expansion and contraction medium in the control cavity 51, further controlling the compression degree of the second spring 54 by the piston block 52, so as to adjust the viscosity of the electrorheological fluid through the pressure data fed back by the pressure sensor 53, and realize the adjustment of the transmission efficiency between the electrorheological fluid in the transmission box 46 and the transmission ring plate 48, so as to adjust the stirring rate of the asphalt according to its temperature, ensure uniform stirring of the asphalt in the initial stage of heating, and avoid unnecessary disturbances in the subsequent stable stage of heating.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
