Description

Technical Field

[0001] This invention relates to the field of fireplace casting production technology, and more particularly to a rapid cooling device for fireplace casting production. Background Technology

[0002] Fireplaces, used for home heating and decoration, are typically made of cast iron or cast steel. The quality of the castings directly affects the performance, appearance, and lifespan of the fireplace. In the production process of fireplace castings, the cooling effect of the high-temperature casting after casting not only affects production efficiency but also has a significant impact on the metallographic structure, dimensional accuracy, and mechanical properties of the castings.

[0003] Chinese Patent CN114603120B discloses a rapid cooling device for high-strength casting processing, comprising a support mechanism, a cooling mechanism fixedly connected to the outer wall of the support mechanism, and a dustproof box. A cleaning brush is movably connected to the right side of the dustproof box, and a motor is fixedly connected to the right side of the cleaning brush. A fixed cylinder is fixedly connected to the top of the dustproof box, and a drying box is fixedly connected to the top of the fixed cylinder. A support block is fixedly connected inside the drying box, and a first mesh cylinder is movably connected to the inner wall of the support block. A first movable cover is movably connected to the right side of the first mesh cylinder. The top of the drying oven is fixedly connected to a fixed pipe, and the end of the fixed pipe away from the drying oven is fixedly connected to a testing box. Although the above patent can cool the castings, the cooling method is usually direct rapid cooling, such as using cold air or cold water for cooling. However, since fireplace castings are mostly gray cast iron or ductile iron parts with uneven thickness, complex structure, and fine relief patterns, their materials are brittle and have poor thermal conductivity. Under rapid cooling conditions, the surface shrinks sharply while the inside is still in a state of high temperature expansion, generating huge thermal stress. After exceeding the tensile strength of the material, it leads to micro-cracks or even overall cracking, which seriously reduces the casting qualification rate and quality.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a rapid cooling device for fireplace casting production is proposed, which can perform gradient cooling on castings, ensure cooling efficiency while avoiding casting defects caused by excessive thermal stress, and improve the casting qualification rate and quality. Summary of the Invention

[0005] To overcome the drawback of fireplace castings where the surface contracts rapidly under rapid cooling while the interior remains in a state of high-temperature expansion, generating enormous thermal stress that exceeds the material's tensile strength, leading to microcracks or even complete rupture and severely reducing the casting's pass rate and quality, this invention provides a rapid cooling device for fireplace casting production that can perform gradient cooling of castings, ensuring cooling efficiency while avoiding casting defects caused by excessive thermal stress, thereby improving the casting's pass rate and quality.

[0006] This invention is achieved through the following technical solution: A rapid cooling device for fireplace casting production includes a housing and electrically driven conveyor rollers installed on both sides of the housing. A shell is fixedly connected to the inner side of the housing, and an air intake fan is fixedly connected between the shell and the housing. A partition plate is fixedly connected inside the shell, dividing the shell into two chambers. The device also includes a gas control assembly mounted on the housing for discharging and blocking hot air. A temperature sensor is installed between the shell and the housing. Control valves that contact the partition plate are symmetrically installed between the shell and the housing. A frame is fixedly connected inside the housing, and exhaust fans are symmetrically installed between the frame and the gas control assembly. The fan is used to draw hot air into the frame for recycling. A heating wire is installed on the frame. An exhaust frame is connected between the frame and the shell. The exhaust end of the exhaust frame is located in the cavity of the shell. Infrared thermometers are symmetrically fixed on both sides of the box. The rear infrared thermometer is electrically connected to the control valve to detect the temperature of the casting and control the opening and closing of the upper and lower control valves accordingly. This allows the cold air and hot air to be discharged and mixed in proportion to form cold air for safe cooling of the casting. An air blowing assembly is set between the inner side of the box and the shell to spray out cold air to cool the casting.

[0007] Further explanation includes a V-shaped plate fixed to the inside of the housing, located to the right of the partition plate.

[0008] Further explanation: The air control component includes a vent frame fixed to the bottom of the housing, the vent frame is connected to the exhaust end of the exhaust fan, and an electrically controlled valve is installed on the vent frame to control the hot air discharged into the vent frame.

[0009] Further explanation: The air blowing assembly includes a vertical pipe connected to the bottom of the housing. The air inlet end of the vertical pipe is located on the left side of the V-shaped plate. An air blowing component is fixed between the two sides of the housing. The air blowing component is located on both sides of the electric conveying roller and is used to spray air to cool the casting. The air inlet end of the air blowing component is fixedly connected to the vertical pipe. An air jet is slidably connected to the air blowing component and is used to spray air to cool a designated position on the casting. A hose is connected between the air inlet end of the air jet and the vertical pipe. An electric screw threadedly connected to the air jet is installed horizontally on the air blowing component. The electric screw is electrically connected to two infrared thermometers on the front side. A tensioning assembly is provided inside the housing. The tensioning assembly contacts the hose and is used to tension the hose.

[0010] Further explanation: The tensioning assembly includes a U-shaped plate symmetrically fixed to the inside of the housing, a guide wheel installed on the top of the U-shaped plate, a hose passing around the guide wheel, a slider slidably connected to the inside of the U-shaped plate, a connecting spring connecting the slider and the U-shaped plate, a tensioning wheel rotatably connected to the slider, and a hose passing around the tensioning wheel. The tensioning wheel is used to tension and guide the hose.

[0011] Further explanation: The rapid cooling device for fireplace casting production also includes a heat dissipation component. The heat dissipation component includes a U-shaped plate symmetrically fixed to an electric conveyor roller. A rack is slidably connected to the inner side of the U-shaped plate. A heat dissipation plate is fixed between the ends of the rack to conduct heat out of the casting. The heat dissipation plate is composed of multiple heat dissipation fins. A drive component is provided on the U-shaped plate to drive the rack to move.

[0012] Further explanation: the drive assembly includes a drive motor mounted on the U-shaped plate, and the output shaft end of the drive motor is fixedly connected to a drive gear that meshes with a rack.

[0013] Further explanation: The rapid cooling device for fireplace casting production also includes a movable frame that slides and snaps onto the frame and the housing. An activated carbon plate is snapped onto the movable frame, and the upper activated carbon plate contacts the partition plate. The activated carbon plate is used to absorb moisture from the cold and hot air.

[0014] The beneficial effects of this invention are as follows: 1. The casting is conveyed into the chamber by an electric conveyor roller. Then, an infrared thermometer on the rear side is activated to monitor the casting temperature in real time. Based on the monitoring results, the opening degree of the control valves on both the upper and lower sides is precisely controlled, and the mixing ratio of cold and hot air is adjusted in real time to keep the cold air temperature at a safe level, thus implementing gradient cooling for the casting. This process ensures cooling efficiency and effectively avoids casting defects caused by excessive thermal stress, significantly improving the pass rate and quality of the castings.

[0015] 2. The front infrared thermometer can accurately locate the high-temperature areas of the casting. Then, the control module controls the electric screw to move the jet nozzle, which concentrates the cold air onto the high-temperature area to achieve localized rapid cooling, ensuring uniform cooling of all parts of the casting and further improving the cooling effect.

[0016] 3. The activated carbon plate effectively adsorbs moisture from both cold and hot air, preventing it from condensing into water and adhering to the casting surface, thus avoiding defects such as porosity and pitting. Furthermore, the movable frame design facilitates the replacement of the activated carbon plate, ensuring continuous and effective adsorption and providing reliable protection for the safe cooling of the casting.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example: A rapid cooling device for fireplace casting production; please refer to [link / reference]. Figures 1-8As shown, the system includes a housing 1 with a door on the left side. Electric conveyor rollers 3 are installed on both the front and rear sides of the housing 1, enabling the conveying of castings. A shell 4 is fixedly connected to the upper inner side of the housing 1. An air intake fan 2 is fixedly connected between the top left side of the shell 4 and the top left side of the housing 1. A partition plate 41 is fixedly connected inside the shell 4, dividing the interior of the shell 4 into upper and lower cavities. A V-shaped plate 42 is fixedly connected to the right side of the shell 4, located to the right of the partition plate 41. The system also includes an air control assembly. The components include a temperature sensor 5, an infrared thermometer 6, a control valve 7, an exhaust frame 71, a frame 72, a heating wire 73, an exhaust fan 74, and an air blowing assembly. An air control assembly is located on the lower right side of the housing 1, which can discharge and block hot air. A temperature sensor 5 is located between the top right side of the housing 4 and the top of the housing 1, between the partition plate 41 and the V-shaped plate 42. Control valves 7 are symmetrically installed between the right side of the housing 4 and the upper part of the housing 1, with two control valves 7 located on the partition plate 41. On both sides below, control valves 7 are in contact with partition plates 41. The upper and lower control valves 7 control cold air and hot air respectively. A frame 72 is fixed to the bottom of the housing 1. Exhaust fans 74 are symmetrically installed on the right side of the frame 72 between the frame and the air control assembly. The exhaust fans 74 are used to draw hot air into the frame 72 for recycling. A heating wire 73 is installed on the top of the frame 72. An exhaust frame 71 is connected between the front top of the frame 72 and the front bottom of the housing 4. The exhaust end of the exhaust frame 71 is located below the partition plate 41 inside the housing 4. Inside the cavity, infrared thermometers 6 are symmetrically fixed to both the front and rear sides of the housing 1. The rear infrared thermometer 6 is electrically connected to the control valve 7. The infrared thermometer 6 is used to detect the temperature of the casting. Then, based on the detected casting temperature, the opening and closing degree of the upper and lower control valves 7 is controlled so that cold air and hot air are discharged and mixed in proportion to form cold air for safe cooling of the casting. An air blowing assembly is provided between the inner side of the housing 1 and the shell 4. When the air blowing assembly is in operation, the air blowing assembly can spray out cold air to cool the casting.

[0031] Please see Figure 3 As shown, the air control assembly includes a ventilation frame 43 and an electric control valve 44. The ventilation frame 43 is fixedly connected to the bottom right side of the housing 1. The left side of the ventilation frame 43 is connected to the exhaust end of the front and rear exhaust fans 74. The electric control valve 44 is installed on the ventilation frame 43. The electric control valve 44 is used to control the hot air discharged into the ventilation frame 43.

[0032] Please see Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the air blowing assembly includes a vertical pipe 8, air blowing components 81, an electric lead screw 82, an air jet component 83, and a tensioning assembly. The vertical pipe 8 is connected to the bottom right side of the housing 4. The air inlet of the vertical pipe 8 is located on the left side of the V-shaped plate 42. Two air blowing components 81 are fixedly connected between the front and rear sides of the housing 1. The air blowing components 81 are located on the upper and lower sides of the electric conveying roller 3. The air blowing components 81 can spray air to cool the casting. The air inlet of the air blowing component 81 is fixedly connected to the vertical pipe 8. Air jet components 83 are slidably connected to both the upper and lower air blowing components 81. When the air jet component 83 moves, it can spray air to cool a designated position on the casting. The air jet component 83 consists of a sliding frame and a nozzle. The sliding frame is slidably connected to the air blowing component 81, and the nozzle is fixedly connected to the inner side of the sliding frame. A flexible hose 84 is connected between the air inlet of both the upper and lower air jet components 83 and the vertical pipe 8. A horizontally mounted hose 84 is installed on the front side of both the upper and lower air blowing components 81. The device is equipped with an electric lead screw 82, which is threadedly connected to the front of the jet component 83. The electric lead screw 82 is also electrically connected to two infrared thermometers 6 on the front. A tensioning assembly is installed inside the housing 1, which contacts the hose 84. The tensioning assembly can tension the hose 84 to prevent it from loosening and knotting. The tensioning assembly includes a guide wheel 85, a return plate 86, a tensioning wheel 87, a slider 88, and a connecting spring 89. The return plate 86 is symmetrically fixed to the upper and lower sides of the right side inside the housing 1. The guide wheel 85 is installed on the front top of the return plate 86. The hose 84 passes around the guide wheel 85. The slider 88 is slidably connected to the inside of the return plate 86. A connecting spring 89 is connected between the front side of the slider 88 and the front side of the return plate 86. The tensioning wheel 87 is rotatably connected to the slider 88. The hose 84 passes around the tensioning wheel 87. The tensioning wheel 87 can tension and guide the hose 84.

[0033] Initially, the electric control valve 44 is closed. First, the operator pulls the door of the housing 1 to open it, moves the casting into the housing 1 and into contact with the electric conveyor roller 3, starts the electric conveyor roller 3 to rotate forward, and the electric conveyor roller 3 rotates forward, driving the casting to the right. When the casting is completely moved into the housing 1, the electric conveyor roller 3 is turned off, the housing door is closed, and then the heating wire 73 is turned on. The heating wire 73 heats the air in the frame 72, so that the air in the frame 72 is heated into hot air. The heated air flows into the exhaust frame 71, and the hot air in the exhaust frame 71 is discharged into the lower cavity of the housing 4 and blocked by the lower control valve 7. The heating wire 73 is turned off, and then the intake fan 2 is turned on. The intake fan 2 draws the outside cold air into the housing 4. The drawn-in cold air is in the upper cavity of the housing 4 and is... The upper control valve 7 is blocked, and then the infrared thermometer 6 and temperature sensor 5 are activated. The rear infrared thermometer 6 detects the temperature of the casting and then controls the opening degree of the upper and lower control valves 7 based on the detected casting temperature. With the upper and lower control valves 7 open, cold air and hot air flow to the right and mix together through the partition plate 41 to form cold air for safe cooling of the casting. The temperature sensor 5 detects the temperature of the mixed cold air and displays it on the terminal, thus providing real-time feedback of the cold air temperature to the operator. The cold air mixed with hot air enters the vertical pipe 8 under the guidance of the V-shaped plate 42. The cold air in the vertical pipe 8 is discharged into the air blowing component 81 and the hose 84. The air blowing component 81 sprays the cold air onto the casting, and the cold air cools the casting. However, the cold air inside the hose 84 is discharged into the jet nozzle 83. Simultaneously, due to the often-designed raised patterns, perforated grids, or locally thickened structures on the surface of the casting, the heat capacity and heat dissipation conditions vary significantly across different areas. The front infrared thermometer 6 detects the areas of the casting with higher temperatures. Then, the control module controls the electric screw 82 to move the jet nozzle 83 to the left. The leftward movement of the jet nozzle 83 moves the hose 84 to the left. The leftward movement of the hose 84, via the guide wheel 85, moves the tension wheel 87 forward. The forward movement of the tension wheel 87 moves the slider 88 forward, compressing the connecting spring 89. When the jet nozzle 83 moves to the left to correspond to the position with the higher temperature of the casting, it stops moving to the left. The jet nozzle 83 then sprays cold air onto the casting. Air cooling is applied to areas with higher temperatures, allowing for rapid cooling of these areas of the casting. Once these areas reach a suitable temperature, the air jet 83 moves to the right and resets, causing the hose 84 to move to the right and reset as well. Due to the action of the connecting spring 89, the slider 88 moves backward and resets, causing the tension wheel 87 to move backward and reset as well. The tension wheel 87 then tightens the hose 84. In this way, the air jet 83 can rapidly cool areas with complex structures in the casting. After the cooling air cools the casting, it becomes hot air that floats inside the housing 1. The exhaust fan 74 is activated, drawing the hot air through the ventilation frame 43 into the frame 72 for recycling. The hot air in the frame 72 is then discharged into the exhaust frame 71, and finally into the housing 4 for reuse. This process is repeated.It can continuously recover and utilize waste heat, effectively reducing energy consumption and improving energy utilization efficiency. As the casting is continuously cooled, the two infrared thermometers 6 on the rear continuously measure the temperature of the casting. The infrared thermometers 6 control the opening and closing of the upper and lower control valves 7 in real time through the control module, thereby controlling the mixing ratio of cold air and hot air in real time, so that the temperature of the cold air can always be kept at a safe value for gradient cooling of the casting, ensuring cooling efficiency while avoiding casting defects caused by excessive thermal stress, thereby improving the qualification rate and quality of the casting. After the casting has cooled, turn off the infrared thermometer 6 and the exhaust fan 74. Simultaneously, start the electric control valve 44 to open it, and then stop the valve to close the ventilation frame 43. The residual heat inside the chamber 1 is then discharged through the ventilation frame 43. After all the residual heat in the chamber 1 has been discharged, turn off the intake fan 2. The jet nozzle 83 and the blowing nozzle 81 stop blowing cold air. Then, start the electric control valve 44 to close it, open the chamber door 1, and start the electric conveyor roller 3 to reverse, moving the cooled casting to the left outside the chamber 1. The operator removes the cooled casting and closes the chamber door 1.

[0034] Please see Figure 9 and Figure 10 As shown, the rapid cooling device for fireplace casting production also includes a heat dissipation assembly, which includes a heat dissipation plate 9, a rack 91, a U-shaped plate 92, and a drive assembly. U-shaped plates 92 are symmetrically fixed to the electric conveyor rollers 3 on both the front and rear sides. Two racks 91 are slidably connected to the inner side of the U-shaped plate 92. A heat dissipation plate 9 is fixed between the ends of the four upper racks 91 and also between the ends of the four lower racks 91. When the heat dissipation plate 9 contacts the casting, it can dissipate the casting temperature. The heat dissipation plate 9 consists of multiple heat dissipation fins. A drive assembly is provided on the U-shaped plate 92. When the drive assembly operates, it can move the racks 91. The drive assembly includes a drive motor 93 and a drive gear 94. The drive motor 93 is installed in the middle of the U-shaped plate 92, and the drive gear 94 is fixed to the output shaft end of the drive motor 93. The drive gear 94 meshes with the racks 91.

[0035] When the casting is conveyed into the housing 1, the drive motor 93 is started, driving the drive gear 94 to reverse. The reverse rotation of the drive gear 94 drives the rack 91 to move, which in turn moves the upper and lower heat dissipation plates 9 relative to each other, bringing them into contact with the surface of the casting. The drive motor 93 is then turned off, the drive gear 94 stops moving the rack 91, and the heat dissipation plates 9 stop moving. The heat dissipation plates 9 then dissipate heat from the casting, further cooling it. Once the casting has cooled, the drive motor 93 is started again, driving the drive gear 94 to rotate forward. The forward rotation of the drive gear 94, through the rack 91, moves the upper and lower heat dissipation plates 9 in opposite directions to their original positions. The drive motor 93 is then turned off. This process accelerates the cooling of the casting, thereby further improving the cooling efficiency.

[0036] Please see Figure 11 As shown, the rapid cooling device for fireplace casting production also includes a movable frame 10 and an activated carbon plate 11. The movable frame 10 is slidably engaged with the rear side of the frame 72 and the rear side of the shell 4. Activated carbon plates 11 are engaged with the upper and lower movable frames 10. The upper activated carbon plate 11 is in contact with the partition plate 41. The activated carbon plate 11 can absorb moisture in the cold and hot air.

[0037] When this device cools the casting, the activated carbon plate 11 adsorbs moisture from the cold and hot air. The moisture-adsorbed hot and cold air can then be reused. After the activated carbon plate 11 has been in use for a long time, the upper and lower movable frames 10 are pulled to detach from the housing 4 and frame 72 respectively, and the activated carbon plate 11 on the movable frame 10 is replaced. After the new activated carbon plate 11 is replaced, the movable frame 10 is returned to its original position. This prevents moisture from condensing into water and adhering to the surface of the casting, which could cause defects such as porosity and pitting, thus further ensuring the safety of the casting.

However, the present invention is not limited to the above embodiments.
