Abstract
Description
Technical Field
[0001] This invention relates to the field of large-volume concrete construction technology, and in particular to a concrete high-level silo aggregate cooling device. Background Technology
[0002] In the construction of large-volume concrete, aggregates, as the main component of concrete, directly affect the mixing temperature and the final placement temperature of the concrete. To control the temperature rise of the concrete, coarse and fine aggregates are cooled before mixing to reduce the concrete outlet temperature and placement temperature, ensuring the construction quality of large-volume concrete, preventing structural cracks caused by temperature stress, and improving the durability and safety of the project.
[0003] Forced ventilation is used to send cold air into the coarse aggregate stockpile, where cooling is achieved through convective heat transfer between the air and the aggregate. However, because the coarse aggregate is piled up inside the silo, it affects air circulation, making it difficult for cold air to penetrate the gaps between the aggregates and reach the center of the aggregate. This results in low aggregate cooling efficiency, and the cold air is difficult to reach the corners of the aggregate silo, easily forming cooling dead zones, making it difficult to guarantee the uniformity of aggregate cooling.
[0004] Therefore, it is necessary to provide a new aggregate cooling device for high-level concrete silos to solve the above problems. Summary of the Invention

[0016] Compared with related technologies, the concrete high-level silo aggregate cooling device provided by the present invention has the following beneficial effects:
[0017] This invention provides a concrete high-level silo aggregate cooling device. When using cold air to cool the aggregate, the partition plate divides the aggregate into two piles, reducing the length of the aggregate piles and facilitating the entry of cold air into the interior of the aggregate piles. Simultaneously, the partition plate divides the interior of the aggregate silo into two spaces. One space is closer to the air conditioner unit. In this space, the cold airflow ejected from the nozzle is inclined along the protective plate and injected into the interior of the aggregate. The cold airflow moves towards the partition plate and away from the air conditioner unit, increasing the distance and time the cold airflow travels within the aggregate, thus improving the heat exchange efficiency of the aggregate. The other space is further away from the air conditioner unit. In this space, the cold airflow ejected from the nozzle moves towards the partition plate, bringing the cold airflow closer to the air conditioner unit. This facilitates the air intake of the air conditioner unit to draw air from this space, thereby ensuring uniform air circulation within both spaces and uniform cooling of the aggregate.
[0018] During aggregate cooling, the fixed shaft rotates clockwise, driving the spiral-shaped first feeding plate to rotate. The first feeding plate pushes the aggregate in the center of the aggregate bin towards the fixed cylinder, facilitating the continuous feeding of the aggregate at the bottom of the partition plate into the fixed cylinder and the feeding pipe. The connecting shaft and the second feeding plate inside the feeding pipe rotate clockwise, pushing the aggregate upwards within the feeding pipe. The feeding pipe is inclined to reduce resistance to the upward movement of the aggregate, allowing it to continuously move within the aggregate bin, constantly changing its position, preventing aggregate accumulation, and facilitating contact between the aggregate and the cold airflow for rapid cooling. The fixed-axis operation drives the vibration mechanism, causing the surface of the partition plate to vibrate rapidly, which in turn vibrates the aggregate. The gaps between the aggregates constantly change, facilitating the passage of cold air and accelerating the heat exchange efficiency of the aggregates. Due to the continuous vibration of the bottom end of the partition plate, the aggregate near the bottom end of the partition plate continuously enters the interior of the fixed plate. The discharge port of the feeding pipe is aligned with the corner of the aggregate bin, causing the aggregate located in the center of the aggregate bin to accumulate at the corner of the aggregate bin through the discharge from the feeding pipe. Under the action of gravity, the material at the corner of the aggregate bin moves towards the center of the aggregate bin, causing the aggregate to be evenly turned over, facilitating the even contact of cold air with each aggregate, and ensuring uniform cooling of the aggregate.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] Please see Figures 1 to 9 , Figure 1 A schematic diagram of a preferred embodiment of the concrete high-level silo aggregate cooling device provided by the present invention; Figure 2 for Figure 1 The diagram shows the internal structure of the aggregate bin. Figure 3 for Figure 2The diagram shows an enlarged view of the structure at point A. Figure 4 for Figure 2 The diagram shows an enlarged view of the structure at point B.

Figure 7 for Figure 2 The diagram shows the distribution of pipes. Figure 8 for Figure 2 The diagram shows the internal structure of the pipe. Figure 9 for Figure 2 The diagram shows the internal structure of the main pipe. A concrete high-level silo aggregate cooling device includes a cooling mechanism 2 for cooling coarse aggregate. The cooling mechanism 2 is installed inside the aggregate silo 1. A support beam 11 for supporting an electric roller shutter door 12 is installed inside the aggregate silo 1. A guide rail 13 is installed on the surface of the aggregate silo 1, and the electric roller shutter door 12 is slidably connected to the guide rail 13. To facilitate opening the electric roller shutter door 12, it moves along the guide rail 13 to seal the top of the aggregate silo 1, preventing free exchange of air inside and outside the silo, greatly reducing cooling loss, ensuring efficient circulation of cold air inside the silo, and simultaneously isolating the external thermal environment from interference with the cooling process.
[0031] The aggregate bin 1 is internally equipped with a partitioning mechanism 5 that separates the aggregate pile. The partitioning mechanism 5 includes a discharge box 51, which is fixed at the center of the bottom of the aggregate bin 1. A partition plate 52 with inverted "V"-shaped sidewalls is installed on the surface of the discharge box 51. Multiple support rods 53 are installed inside the partition plate 52, and multiple sliding plates 54 are installed on the sidewalls of the partition plate 52. The sidewalls of the sliding plates 54 are trapezoidal. When coarse aggregate enters the aggregate bin 1, the aggregate flows along the partition plate 54... The partition plate 52 moves downwards, and the aggregate contacts the trapezoidal sliding plate 54 on the side wall and moves downwards along the sliding plate 54, facilitating the uniform entry of the aggregate into the aggregate bin 1. The thickness of the sliding plate 54 gradually increases from top to bottom, increasing its wear resistance and preventing the aggregate from damaging the sliding plate 54 and the partition plate 52. After the coarse aggregate is placed into the aggregate bin 1, the partition plate 52 divides the aggregate into two piles, reducing the length of the aggregate piles and facilitating the entry of cold air into the aggregate piles. One of the branch pipes 25 connects to the interior of the partition plate 52, and the surface of the partition plate 52 is provided with multiple funnel-shaped through holes 55. During the cooling process of the coarse aggregate, cold air is sprayed into the interior of the coarse aggregate through the through holes 55, increasing the contact area between the cold air and the coarse aggregate and improving the cooling efficiency.
[0032] The side wall of the separating mechanism 5 is equipped with a feeding mechanism 4 for driving the coarse aggregate to tumble. The feeding mechanism 4 includes a fixing plate 45, which is fixed to the bottom of the aggregate bin 1. The bottom surface of the aggregate bin 1 is inclined towards the fixing plate 45 to facilitate the sliding of the aggregate inside the aggregate bin 1 towards the fixing plate 45. One end of the fixing plate 45 is connected to a frustum-shaped fixing cylinder 42, and both the fixing cylinder 42 and the fixing plate 45 are rotatably connected to a fixing shaft 43 and a first feeding plate 44. The side wall of the fixing shaft 43 is equipped with a spiral-shaped first feeding plate 44. A first feeding plate 44 is installed at both ends of the fixed shaft 43 in opposite directions; fixed cylinders 42 are installed on both sides of the aggregate bin 1, and feeding pipes 41 are installed obliquely and symmetrically at one end of the fixed cylinders 42. The feeding pipes 41 are obliquely located on the side wall of the aggregate bin 1, and the outlet of the feeding pipes 41 is aligned with the corner of the aggregate bin 1; the internal part of the feeding pipes 41 is rotatably connected to a connecting shaft 46 and a second feeding plate 47, and a spiral second feeding plate 47 is installed on the side wall of the connecting shaft 46; when the coarse aggregate is cooled, the fixed shaft 43... Rotating clockwise, the fixed shaft 43 drives the spiral-shaped first feeding plate 44 to rotate. The first feeding plate 44 pushes the aggregate in the center of the aggregate bin 1 towards the fixed cylinder 42. Due to the continuous vibration of the bottom end of the partition plate 52, the aggregate near the bottom end of the partition plate 52 continuously enters the interior of the fixed plate 45, facilitating the first feeding plate 44 to continuously feed the aggregate at the bottom end of the partition plate 52 into the interior of the fixed cylinder 42 and the feeding pipe 41. The connecting shaft 46 and the second feeding plate inside the feeding pipe 41... 47. Rotating clockwise pushes the aggregate upwards continuously inside the feeding pipe 41. The feeding pipe 41 is inclined to reduce the resistance to the upward movement of the aggregate. The discharge port of the feeding pipe 41 is aligned with the corner of the aggregate bin 1, so that the aggregate located in the center of the aggregate bin 1 accumulates at the corner of the aggregate bin 1 through the discharge of the feeding pipe 41. Under the action of gravity, the material at the corner of the aggregate bin 1 moves towards the center of the aggregate bin 1, so that the aggregate is evenly turned over, which facilitates the even contact of cold air with each piece of aggregate, so that the aggregate is evenly cooled.
[0033] Drive mechanisms 3 for rotating the fixed shaft 43 and the connecting shaft 46 are installed on both sides of the aggregate bin 1. Each drive mechanism 3 includes a drive housing 32, symmetrically mounted at the bottom of the aggregate bin 1. A servo motor 31 is mounted on the side wall of one of the drive housings 32, and the output shaft of the servo motor 31 is connected to the fixed shaft 43. Both ends of the fixed shaft 43 are fixedly connected to main gears 33. A first gear 34 and a bevel gear 35 are rotatably connected inside the drive housing 32, with the main gear 33 meshing perpendicularly with the first gear 34. The top ends of the first gear 34 and the bevel gear 35 are fixedly connected to belt shafts 36, which are connected by a belt 37. Both sides of the bevel gear 35 mesh with the second gear 38, and the bottom end of the connecting shaft 46 is fixedly connected to the second gear 38. When the servo motor 31 rotates, driving the fixed shaft 34 to rotate clockwise, the fixed shaft 34 drives the main gear 33 to rotate clockwise, and the main gear 33 drives the first gear 34 to rotate counterclockwise. The first gear 34, through the belt shaft 36 and the belt 37, drives the bevel gear 35 to rotate counterclockwise, and the bevel gear 35 drives the second gear 38 to rotate clockwise, thus preventing the second feeding plate 47 from pushing the material upwards. The diameter of the main gear 33 is much larger than the diameter of the first gear 34, and the diameter of the bevel gear 35 is larger than the diameter of the second gear 38, so that the rotational speed of the second gear 38 is much greater than the rotational speed of the main gear, facilitating the second feeding plate 47 to push the material upwards.
[0034] The partition mechanism 5 is internally equipped with a vibration mechanism 7 that vibrates the surface of the partition plate 52. The vibration mechanism 7 includes a connecting plate 71, which is fixed at the center of the inside of the feeding box 51. A third gear 72 is rotatably connected inside the connecting plate 71, and the third gear 72 is fixedly connected to the fixed shaft 43. A rotating shaft 74 and a fourth gear 73 are rotatably connected inside the partition plate 52, and the rotating shaft 74 and the fourth gear 73 are fixedly connected. The fourth gear 73 meshes with the third gear 72. A mounting box 76 is symmetrically fixedly connected inside the partition plate 52. An eccentric block 75 and the rotating shaft 74 are rotatably connected inside the mounting box 76, and the eccentric block 75 is fixed to the rotating shaft 74. At the end of the fixed shaft 43, when the fixed shaft 43 rotates, it drives the third gear 72 to rotate, and the third gear 72 drives the fourth gear 73 to rotate. The diameter of the third gear 72 is much larger than the diameter of the fourth gear 73, so that the rotational speed of the fourth gear 73 is much greater than that of the third gear 72. The fourth gear 73 drives the rotating shaft 74 and the eccentric block 75 to rotate rapidly. The centrifugal force generated by the high-speed rotation of the eccentric block 75 is used to generate a vibration force, which causes the surface of the partition plate 52 to vibrate rapidly, causing the aggregate to vibrate. The gaps between the aggregates change continuously, which facilitates the passage of cold air and accelerates the heat exchange efficiency of the aggregates. With the vibration of the partition plate 52, the aggregates on the side wall of the partition plate 52 are placed inside the fixed plate 45, which facilitates the movement of the aggregates.
[0035] The cooling mechanism 2 includes an outdoor unit 21 and an indoor unit 22. The outdoor unit 21 is installed on the surface of the aggregate bin 1, and the indoor unit 22 is installed at the top of the aggregate bin 1. An air inlet 23 is installed on the side wall of the indoor unit 22, and a main pipe 24 is installed on the side wall of the indoor unit 22. The main pipes 24 are symmetrically distributed inside the top of the aggregate bin 1. Multiple branch pipes 25 are installed on the side wall of the main pipe 24, and multiple nozzles 27 are provided on the side wall of the branch pipes 25. When the outdoor unit 21 and the indoor unit 22 operate, they generate cold airflow, which passes through the main pipe 24 and the branch pipes 25 and is then sprayed out from the nozzles 27. The cold airflow comes into contact with the aggregate and cools it. The indoor unit 22 draws in air from inside the aggregate bin 1 through the air inlet 23, cools the air, and then delivers it into the interior of the main pipe 24, realizing the circulation of air inside the aggregate bin 1 and preventing cold leakage.
[0036] On the same branch pipe 25, the spacing between adjacent nozzles 27 gradually increases from top to bottom; to allow more cold airflow to spray out from the bottom of the branch pipe 25 and contact the aggregate, and then for the cold airflow to pass through the gaps in the aggregate and move upward, increasing the contact time between the cold airflow and the aggregate, and improving the cooling effect of the aggregate; multiple arc-shaped protective plates 26 are installed on the side wall of the branch pipe 25, and the protective plates 26 cover the nozzles 27, so as to facilitate the protection of the nozzles 27 by the protective plates 26 and prevent the aggregate from clogging the nozzles 27; and the cold airflow sprayed from the nozzles 27 is all inclined towards the partition plate 52, which divides the interior of the aggregate bin 1 into two spaces, one of which is close to In the space of the air conditioner indoor unit 22, the cold airflow ejected from the nozzle 27 is inclined along the protective plate 26 and injected into the interior of the aggregate. The cold airflow moves towards the partition plate 52 and moves away from the air conditioner indoor unit 22, increasing the distance and time the cold airflow moves inside the aggregate and improving the heat exchange efficiency of the aggregate. In another space away from the air conditioner indoor unit 22, the cold airflow ejected from the nozzle 27 moves towards the partition plate 52, causing the cold airflow to move closer to the air conditioner indoor unit 22. This facilitates the air intake 23 of the air conditioner indoor unit 22 to draw air from this space, thereby making the air in the two spaces circulate evenly and cooling the aggregate evenly.
[0037] Multiple guide vanes 28 are installed at an angle inside the main pipe 24. The guide vanes 28 are located on one side of the air inlet of the branch pipe 25. The guide vanes 28 contact the cold airflow inside the main pipe 24, allowing the cold airflow to enter the interior of the branch pipe 25 along the guide vanes 28. The tilt angle of the guide vanes 28 gradually increases along the flow direction of the cold airflow inside the main pipe 24. The larger the tilt angle of the guide vanes 28, the easier it is for the cold airflow to enter the interior of the branch pipe 25. By controlling the tilt angle of the guide vanes 28, the cold airflow can be evenly entered into the interior of each branch pipe 25.
[0038] The top of the feeding box 51 is fixedly connected to the fixing plate 45. The inside of the feeding box 51 is rotatably connected to the fixing shaft 43 and the first feeding plate 44. In order to facilitate the counterclockwise rotation of the fixing shaft 43 and the first feeding plate 44, the aggregate inside the fixing plate 45 is pushed into the inside of the feeding box 51, and the cooled aggregate is discharged through the feeding box 51.
[0039] Bearings 6 are installed at the connection points of the fixed shaft 43 and the fixed cylinder 42, the connection points of the connecting shaft 46 and the feeding pipe 41, the connection points of the fixed shaft 43 and the connecting plate 71, and the connection points of the rotating shaft 74 and the mounting box 76, in order to facilitate the rotation of the fixed shaft 43, the connecting shaft 46 and the rotating shaft 74.
[0040] The working principle of the concrete high-level silo aggregate cooling device provided by this invention is as follows: After coarse aggregate is placed inside the aggregate silo 1, the device is connected to an external power source, and the electric roller shutter door 12 is opened, causing the electric roller shutter door 12 to move along the guide rail 13, sealing the top of the aggregate silo 1 and forming a sealed space inside the aggregate silo 1. The outdoor unit 21 and the indoor unit 22 of the air conditioner are turned on to cool the aggregate. The operation of the outdoor unit 21 and the indoor unit 22 of the air conditioner generates a cold airflow, which passes through the main pipe 24 and the branch pipe 25 and is then sprayed out from the nozzle 27 and the through hole 55. The cold airflow comes into contact with the aggregate, cooling the aggregate. Meanwhile, the indoor unit 22 of the air conditioner draws in air from inside the aggregate silo 1 through the air inlet 23, cools the air, and then delivers it into the interior of the main pipe 24, realizing the circulation of air inside the aggregate silo 1 and preventing cold leakage. Inside the aggregate bin 1, the partition plate 52 divides the aggregate into two piles, reducing the length of the aggregate piles and facilitating the entry of cold air into the interior of the aggregate piles. The partition plate 52 divides the interior of the aggregate bin 1 into two spaces. One space is closer to the air conditioner unit 22. In this space, the cold airflow ejected from the nozzle 27 is inclined along the protective plate 26 and injected into the interior of the aggregate. The cold airflow moves towards the partition plate 52 and away from the air conditioner unit 22, increasing the distance and time the cold airflow travels within the aggregate and improving the heat exchange efficiency. The other space is further away from the air conditioner unit 22. In this space, the cold airflow ejected from the nozzle 27 moves towards the partition plate 52, bringing the cold airflow closer to the air conditioner unit 22. This facilitates the air intake 23 of the air conditioner unit 22 drawing air from this space, resulting in uniform air circulation within both spaces and uniform cooling of the aggregate. Simultaneously, some of the cold airflow is injected into the aggregate through the through-holes 55 on the side wall of the partition plate 52, allowing the cold airflow to contact the aggregate from different directions (the flow direction of the cold airflow within the aggregate bin 1 is shown in the attached figure). Figure 6As shown), to accelerate aggregate cooling efficiency. During aggregate cooling, the servo motor 31 is turned on, and the fixed shaft 43 rotates clockwise. The fixed shaft 43 drives the spiral first feeding plate 44 to rotate. The first feeding plate 44 pushes the aggregate in the center of the aggregate bin 1 towards the fixed cylinder 42, so that the first feeding plate 44 can continuously feed the aggregate at the bottom of the partition plate 52 into the fixed cylinder 42 and the feeding pipe 41. The connecting shaft 46 and the second feeding plate 47 inside the feeding pipe 41 rotate clockwise, pushing the aggregate to move upward continuously inside the feeding pipe 41. The feeding pipe 41 is inclined to reduce the resistance of the aggregate moving upward, so that the aggregate moves continuously inside the aggregate bin 1, constantly changing the position of the aggregate, avoiding aggregate accumulation, and facilitating contact between the aggregate and the cold airflow, so that the aggregate cools down quickly. When the fixed shaft 43 rotates, it drives the third gear 72 to rotate. The third gear 72 drives the fourth gear 73 to rotate rapidly. The fourth gear 73 drives the rotating shaft 74 and the eccentric block 75 to rotate rapidly. The centrifugal force generated by the high-speed rotation of the eccentric block 75 generates a vibration force, causing the surface of the partition plate 52 to vibrate rapidly, which in turn causes the aggregate to vibrate. The gaps between the aggregates change continuously, facilitating the passage of cold air and accelerating the heat exchange efficiency of the aggregates. Due to the continuous vibration of the bottom end of the partition plate 52, the aggregates near the partition plate 52 vibrate rapidly. Aggregate near the bottom of the partition plate 52 continuously enters the interior of the fixed plate 45, while the outlet of the feeding pipe 41 is aligned with the corner of the aggregate bin 1. This causes the aggregate located at the center of the aggregate bin 1 to accumulate at the corner of the aggregate bin 1 through the discharge from the feeding pipe 41. Under the action of gravity, the material at the corner of the aggregate bin 1 moves towards the center of the aggregate bin 1, causing the aggregate to be evenly turned over, facilitating even contact between the cold air and each piece of aggregate for uniform cooling. When the aggregate is cooled and ready for use, the servo motor 31 is turned on, and the fixed shaft 43 rotates counterclockwise. The first feeding plate 44 pushes the aggregate continuously into the interior of the discharge box 51, while the partition plate 52 vibrates continuously, facilitating the aggregate inside the aggregate bin 1 to fall into the interior of the fixed plate 45. This causes the first feeding plate 44 to continuously push out coarse aggregate, accelerating the discharge efficiency.
