Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesium-carbon brick cooling technology, and in particular to a magnesium-carbon brick cooling device with adjustable air outlet angle. Background Technology
[0002] In the production of magnesia-carbon bricks, the brick blanks are first placed in a heating furnace for high-temperature heating. After heating, they are cooled for a period of time before being removed along with their support frames. At this point, the magnesia-carbon bricks still retain a significant amount of residual heat, and allowing them to cool naturally takes a considerable amount of time. Therefore, additional equipment is needed to assist in cooling. Currently, fans are commonly used to blow air onto the magnesia-carbon bricks for auxiliary cooling. However, the air blown by the fans is at room temperature, resulting in low heat exchange efficiency with the magnesia-carbon bricks. Furthermore, the airflow cannot be adjusted vertically, easily creating dead zones and affecting the cooling effect. Therefore, there is an urgent need to develop a magnesia-carbon brick cooling device that uses low-temperature airflow to cool the magnesia-carbon bricks, achieving higher heat exchange efficiency. This device utilizes a spiral airflow to contact the magnesia-carbon bricks, transforming the heat exchange between the airflow and the brick surface from laminar to turbulent flow, thus improving heat dissipation efficiency. Additionally, the device allows for vertical adjustment of the airflow direction to eliminate dead zones, resulting in even better cooling. This adjustable airflow angle device overcomes the shortcomings of current applications and meets current needs. Utility Model Content
[0003] The purpose of this invention is to provide a magnesium-carbon brick cooling device with an adjustable air outlet angle to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A magnesia-carbon brick cooling device with adjustable air outlet angle includes a water tank, an industrial chiller, a water pump, a fan, a base, heat exchange tubes, air blowing cooling mechanisms, and an oscillating mechanism. The water tank is filled with water. The inlet of the industrial chiller is connected to the water tank via the water pump, and the outlet of the industrial chiller is connected to the water tank via a pipe. The heat exchange tubes are disposed inside the water tank. The air delivery end of the fan is fixedly connected to the lower end of the heat exchange tubes. A diverter pipe is fixedly connected to the upper end of the heat exchange tubes and is fixed to the base. Multiple air blowing cooling mechanisms are included, each rotatably connected to the base. The oscillating mechanism… The mechanism is mounted on a base and is used to drive multiple air-blowing cooling mechanisms to swing up and down. Each air-blowing cooling mechanism includes: a duct, a nozzle, a hose, and a spiral channel. Multiple nozzles are fixed on the duct. The duct is flexibly connected to a distribution pipe through a hose. Each nozzle has a spiral channel. The swinging mechanism includes: an electric telescopic rod, a rack, and gears. The electric telescopic rod is fixed on the base. The telescopic end of the electric telescopic rod is fixed to the rack. There are multiple gears, and each gear is fixed on a duct. The rack and gears mesh with each other.
[0006] Preferably, two sliders are fixed to the back of the rack.
[0007] Preferably, a slide rail is fixed on the base, and the slider is slidably mounted on the slide rail.
[0008] Preferably, the heat exchange tube is made of copper.
[0009] The beneficial effects of this utility model are as follows: When using this adjustable air outlet angle magnesia-carbon brick cooling device, the magnesia-carbon bricks taken from the heating furnace are moved to the front of the air-blowing cooling mechanism. Air is blown into the heat exchange tubes by a fan, and water is pumped from the water tank to an industrial chiller. The industrial chiller cools the water before sending it back to the water tank, keeping the water in the tank at a low temperature. This cold water cools the airflow in the heat exchange tubes, thereby lowering the air temperature. The low-temperature airflow has a higher cooling efficiency for the magnesia-carbon bricks. The low-temperature airflow enters the duct from the distribution pipe, then passes through the spiral channel in the nozzle, and finally exits in a spiral shape, washing over the surface of the magnesia-carbon bricks. The centrifugal force of the rotating airflow disrupts the laminar boundary layer formed on the brick surface, changing the heat exchange between the airflow and the brick surface from "laminar heat exchange" to "turbulent heat exchange." This invention improves heat exchange efficiency by using a spiral airflow that travels along a spiral trajectory on the brick surface. Compared to a straight airflow, the spiral airflow has a longer contact path with the magnesia-carbon brick, resulting in more thorough heat exchange. Simultaneously, an electric telescopic rod moves a rack up and down, which in turn rotates a gear, which in turn rotates the duct and nozzle. This allows for adjustments to the airflow direction, ensuring more complete contact between the airflow and the magnesia-carbon brick, leading to better cooling. In summary, this invention uses a low-temperature airflow to cool magnesia-carbon bricks, resulting in higher heat exchange efficiency. Furthermore, the spiral airflow transforms the heat exchange between the airflow and the brick surface from laminar to turbulent flow, improving heat dissipation efficiency. The vertical adjustment of the airflow direction also eliminates dead zones, further enhancing the cooling effect. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Specific implementation examples are given below.
[0021] See Figures 1 to 7In this embodiment of the invention, a magnesium-carbon brick cooling device with adjustable air outlet angle includes a water tank 1, an industrial chiller 2, a water pump 3, a fan 4, a base 5, a heat exchange tube 6, a blowing cooling mechanism 7, and a swing mechanism 8. The water tank 1, industrial chiller 2, water pump 3, fan 4, and base 5 are all mounted on the ground. The water tank 1 is filled with water. The inlet of the industrial chiller 2 is connected to the water tank 1 via the water pump 3, and the outlet of the industrial chiller 2... The water in the tank is cooled by an industrial chiller 2 connected to a water tank 1 via a pipe. The heat exchange tube 6 is installed inside the water tank 1. The air delivery end of the fan 4 is fixedly connected to the lower end of the heat exchange tube 6. A diversion pipe 601 is fixedly connected to the upper end of the heat exchange tube 6 and is fixed to the base 5. Multiple air-blowing cooling mechanisms 7 are rotatably connected to the base 5. These mechanisms are used to blow air onto the magnesia-carbon bricks for cooling. The swing mechanism 8 is mounted on the base 5 and is used to drive multiple air-blowing cooling mechanisms 7 to swing up and down. The air-blowing cooling mechanism 7 includes: a duct 701, a nozzle 702, a hose 703, and a spiral channel 704. Multiple nozzles 702 are fixed on the duct 701. The duct 701 is flexibly connected to the diversion pipe 601 through the hose 703. Each nozzle 702 is provided with a spiral channel 704. The spiral channel 704 makes the airflow blown out from the nozzle 702 spiral. When the airflow sweeps the surface of the magnesia-carbon brick in a spiral shape, the centrifugal force of the rotating airflow will destroy the laminar boundary layer formed on the surface of the brick, so that the heat exchange between the airflow and the surface of the brick changes from "laminar heat exchange" to "turbulent heat exchange", which improves the heat dissipation efficiency. Moreover, the spiral airflow moves forward on the surface of the brick in a spiral trajectory. Compared with the straight airflow, the spiral airflow has a longer contact path with the magnesia-carbon brick, so that the heat exchange is more complete.
[0022] The heat exchange tube 6 is made of copper, which gives it good thermal conductivity.
[0023] The swing mechanism 8 includes an electric telescopic rod 801, a rack 802, and a gear 803. The electric telescopic rod 801 is fixed to the base 5, and the telescopic end of the electric telescopic rod 801 is fixed to the rack 802. There are multiple gears 803, each of which is fixed to a guide tube 701. The rack 802 and the gear 803 mesh with each other. Two sliders 8021 are fixed to the back of the rack 802. A slide rail 8022 is fixed on the base 5, and the sliders 8021 are slidably mounted on the slide rail 8022. In use, the electric telescopic rod 801 drives the rack 802 to move up and down, the rack 802 drives the gear 803 to rotate up and down, and the gear 803 drives the guide tube 701 and the nozzle 702 to rotate up and down, thereby adjusting the blowing direction of the nozzle 702 and making the airflow more fully contact the magnesia-carbon brick.
[0024] A PLC controller 9 is installed on the base 5. The industrial chiller 2, water pump 3, fan 4 and electric telescopic rod 801 are all controlled by the PLC controller 9.
[0025] Working Principle: This adjustable airflow angle magnesia-carbon brick cooling device works by moving the magnesia-carbon bricks removed from the heating furnace to the front of the airflow cooling mechanism 7. Air is blown into the heat exchange tubes 6 by the fan 4. Water is drawn from the water tank 1 by the water pump 3 and transported to the industrial chiller 2. The industrial chiller 2 cools the water before returning it to the water tank 1, keeping the water in the tank 1 at a low temperature. This cold water cools the airflow within the heat exchange tubes 6, thus lowering the air temperature. The low-temperature airflow has a higher cooling efficiency for the magnesia-carbon bricks. The low-temperature airflow enters the duct 701 from the distribution pipe 601, then passes through the spiral channel 704 within the air nozzle 702, finally exiting in a spiral shape and washing the surface of the magnesia-carbon bricks. The centrifugal force of the rotating airflow disrupts the laminar boundary layer formed on the brick surface, transforming the heat exchange between the airflow and the brick surface from "laminar heat exchange" to "turbulent heat exchange," thus improving heat dissipation efficiency. Moreover, the spiral airflow travels along a spiral trajectory on the brick surface, resulting in a longer contact path with the magnesia-carbon brick compared to a straight airflow, leading to more thorough heat exchange. Simultaneously, the electric telescopic rod 801 drives the rack 802 to move up and down, which in turn drives the gear 803 to rotate up and down. The gear 803 then drives the duct 701 and the nozzle 702 to rotate up and down, allowing the blowing direction of the nozzle 702 to be adjusted in different ways, resulting in more thorough contact between the airflow and the magnesia-carbon brick and a better cooling effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
