Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment cooling technology, specifically a metallurgical equipment cooling device. Background Technology

[0002] Metallurgical equipment refers to a series of machines and devices used in the production processes of metal smelting, processing and finishing. Its core task is to realize the extraction, purification and shaping of metal materials. In the production and processing of metallurgical equipment, cooling devices are often used to solve the high temperature problem generated in the production process, and to ensure the stable operation of equipment and product quality.

[0003] The prior art patent document CN222824837U provides a device for facilitating the cooling of metallurgical equipment, comprising a base plate; a metallurgical furnace is disposed on the top of the base plate; a fixing rod is fixedly connected to the side wall of the metallurgical furnace; the fixing rods are evenly distributed on the side wall of the metallurgical furnace; a fixing ring is fixedly connected to the end of each set of fixing rods; a sliding ring is slidably fitted to the side wall of the fixing ring; a stirring plate is fixedly connected to the bottom of the sliding ring; the stirring plates are evenly distributed at the bottom of the sliding ring; a rotating platform is disposed on the top of the base plate; and the metallurgical furnace is disposed in the middle of the rotating platform. This step, through the setting of the rotating platform, allows the rotating stabilizing rod to rotate, thereby driving the sliding ring to rotate. The stirring plate agitates the air, causing cold air and the coolant from the spray assembly to adhere to the surface of the metallurgical furnace for cooling. The fixing rods and fixing rings make the rotation of the sliding ring more stable, enhancing the cooling effect of the device for facilitating the cooling of metallurgical equipment.

[0004] Although the device has many beneficial effects, it still has the following problems: The rotating system consisting of the fixed ring, sliding ring and stabilizing rod on the outside of the metallurgical pot has radial micro-vibration, which affects the stability of operation. In addition, the rotating mechanism lacks an active drive device. Secondly, the cooling structure consisting of the gas collecting hood and louvers cannot achieve atomized spraying. Large droplets of coolant are prone to forming a vapor film on the surface of the metallurgical pot, resulting in low heat exchange efficiency. Furthermore, the louver design weakens the air cooling effect, and the airflow turbulence coefficient is low, resulting in insufficient residence time of atomized droplets. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a cooling device for metallurgical equipment, including:

[0035] Please see Figures 1-5This embodiment of a metallurgical equipment cooling device includes a rotating assembly 100, which includes a worktable 110. A ring frame 130 and a ring frame 21 are fixedly connected to the top of the worktable 110. A sliding frame 150 is slidably connected to the top of the ring frame 130 and the ring frame 21. A cooling assembly 200 is provided on the top of the sliding frame 150. The cooling assembly 200 includes a nozzle assembly 250, a water pump 220, a liquid storage tank 240, and a fan 260.

[0036] It is worth noting that, in order to drive the sliding frame 150 to rotate, specifically, two motors 120 are fixedly connected to the top two ends of the workbench 110 by screws. A bevel gear 121 is fixedly connected to the output end of the motor 120. A button 111 electrically connected to the motor 120 is fixedly connected to the top of the workbench 110 for controlling the start and stop of the motor 120. A placement platform 113 is welded to the center of the top of the workbench 110 for placing metallurgical equipment. Multiple drainage channels are opened on the top of the workbench 110 for draining excess coolant. A filter plate 112 is fixedly connected to the top of the drainage channel for filtering the drained coolant. A collection tank 160 is fixedly connected to the bottom of the workbench 110 for collecting the filtered coolant.

[0037] Next, to facilitate the rotation and sliding of the sliding frame 150 on top of the annular frame 130 and the annular frame 21, specifically, annular grooves are provided on the top of both the annular frame 130 and the annular frame 21. Multiple rollers 132 are rotatably connected to the bottom of the annular groove to reduce sliding friction. A reflector plate 140 is fixedly connected to the inner circumference of the annular frame 2131 to reflect airflow. Multiple sliders that match the shape and size of the groove are integrally formed on the bottom of the sliding frame 150 to facilitate the rotation and sliding of the sliding frame 150. A button 2 152 that electrically connects the water pump 220 and the fan 260 is fixedly connected to the top of the sliding frame 150 to enable the fan 260 and the water pump 220 to start and stop synchronously. A bevel gear ring 151 is welded to the top of the sliding frame 150. The outer circumference of the bevel gear ring 151 is vertically meshed with a bevel gear 121 to facilitate the motor 120 to drive the sliding frame 150 to rotate and slide.

[0038] Meanwhile, to cool the metallurgical equipment, the cooling assembly 200 includes a bracket 210. A circular groove is formed on the side wall of the bracket 210, and a water pump 220 is inserted into the inner circumference of the groove, causing the coolant to form an active water flow that flows towards the nozzle assembly 250. A connecting water pipe 230 is inserted into the input end of the water pump 220, and the other end of the connecting water pipe 230 is connected to a storage tank 240. A cap 241 is threaded onto the top of the storage tank 240 for sealing and facilitating the addition of coolant. The nozzle assembly 250 is embedded in the side of the bracket 210 for spraying coolant. The nozzle assembly 250 includes a first nozzle 251, a second nozzle 252, and a third nozzle 253. The first nozzle 251 is an anti-splash atomizing nozzle used to form a fan-shaped large droplet atomized airflow. In the lower part of the metallurgical equipment, nozzle 252 is a standard atomizing nozzle used to form a solid cone-shaped spray to cool the medium-temperature zone in the middle of the metallurgical equipment. Nozzle 3 253 is an ultra-fine atomizing nozzle used to spray broken droplets to cover the upper part of the metallurgical equipment, cooling the equipment through droplet evaporation. The input end of nozzle group 250 is connected to the output end of water pump 220, which provides coolant. A mounting base 211 is welded to the top of bracket 210, and a fan 260 is fixedly connected to the top of mounting base 211. The output end of fan 260 is tilted downward at 30 degrees to provide cooling airflow to the metallurgical equipment and blow the atomized coolant towards the metallurgical equipment. A guide component 270 is fixedly connected to the output end of fan 260 to improve the cooling airflow and enhance cooling efficiency.

[0039] Furthermore, in order to drain the collected coolant, specifically, a drain pipe 161 is connected to the bottom of the outer wall of the collection tank 160 for draining the collected coolant. It can be filtered and purified by connecting an external filter or discharged directly. A switch valve 162 is connected to the output end of the drain pipe 161 for controlling the discharge of the drain pipe 161.

[0040] It is worth noting that, in order to reflect the airflow and improve cooling efficiency, the reflector plate 140 specifically includes multiple connecting plates for connecting the annular frame 131. The sidewalls of the connecting plates are welded with truncated cone annular plates with a cone angle of 60 degrees, which are used to reflect the cooling airflow so that it swirls upward and diffuses radially, so that the cooling airflow forms a vortex field and prolongs the residence time of the coolant atomized droplets.

[0041] Finally, in order to increase the speed of the cooling airflow, the guide component 270 includes a frame 271 for mounting the guide plate 272. A circular exhaust groove is provided on the top of the frame 271. Multiple guide plates 272 are fixedly connected to the inner circumference of the exhaust groove. The multiple guide plates 272 are evenly distributed. When the airflow is discharged from the fan output end, it passes through the guide plate 272 to form a vortex and increase the airflow speed.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of the metallurgical equipment cooling device of this embodiment is as follows:

[0044] 1: Place the metallurgical equipment on the top of the placement platform 113, then press button 2 152 to start the fan 260 and water pump 220, then press button 1 111 again to start the two motors 120. The motors 120 drive the bevel gear 121 to rotate, and the bevel gear 121 drives the meshing bevel gear ring 151 to rotate. The bevel gear ring 151 drives the sliding frame 150 to rotate and slide inside the annular groove at the top of the annular frame 130 and the annular frame 131, so that the cooling component 200 performs a surrounding cooling of the metallurgical equipment.

[0045] 2: After the fan 260 starts, it forms an active cooling airflow, and the airflow velocity is increased by the guide 270. At the same time, the water pump 220 transfers the coolant inside the storage tank 240 to the nozzle group 250 through the water pipe. Then, the nozzle group 250 cools the outside of the metallurgical equipment. The cooling airflow makes the atomized coolant adhere to the outer wall of the metallurgical equipment for cooling. Afterwards, the cooling airflow swirls upward and diffuses radially through the reflector 140, which increases the residence time of the atomized coolant and improves the cooling efficiency.

[0046] 3: When excess coolant drips from the outer wall of the metallurgical equipment or the surface of the reflector plate 140, the coolant is initially filtered through the filter plate 112 and flows naturally into the collection tank 160. Then, the drain pipe 161 on the outer circumference of the collection tank 160 can be connected to an external filter or a drain port, and the switch valve 162 can be opened to discharge it.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
