Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting sampling technology, specifically a cooling device for a molten steel sampler. Background Technology

[0002] Steel samplers are used to extract samples from molten steel at high temperatures for chemical composition analysis. Because the temperature of molten steel is extremely high (typically above 1500°C), the sampler heats up rapidly upon contact with the molten steel. If not cooled promptly, this can lead to damage to the sampler or a decrease in sample quality.

[0003] According to Chinese Patent CN220136726U, a cooling device for a molten steel sampler is proposed. In this device, the clamping mechanism is calibrated by starting a first motor, so that the support frame is placed at the bottom of the guide rod and can support the sampler. The second motor is started, so that the bracket can smoothly approach the sampler located on the support frame. The cylinder and the baffle on the guide rod can clamp the sampler onto the support frame. Water is injected into the shell, and the water level in the shell is controlled within a certain range through the water outlet groove, so that the water in the shell contacts the sampler and does not exceed the wall thickness of the holes at both ends of the sampler. This solves the problem in the prior art that when the sampler is water-cooled, the sampler is in direct contact with the water, and the water flows into the mold cavity through the holes at both ends of the molten steel sampler, which causes the sampling results to be inaccurate.

[0004] In existing technologies, when smelting in an electric furnace, it is necessary to sample and measure the elements and temperature of the molten steel. However, the current method of cooling the molten steel after sampling with the steel sampling gun has some problems. Currently, a cooling water tank is prepared next to the furnace platform. This method poses significant safety risks and does not meet the requirements of national metallurgical standards. Therefore, we propose a cooling device for the molten steel sampler. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for a molten steel sampler, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a molten steel sampler, comprising a mounting plate and a temperature measuring component disposed on the top of the mounting plate. The temperature measuring component includes a large water tank fixedly connected to the top of the mounting plate. A fixing frame is fixedly connected to the top outer wall of the large water tank. A forward and reverse motor is fixedly connected to the inner wall of the fixing frame. An output shaft is fixedly connected to the output end of the forward and reverse motor. The other end of the output shaft is rotatably connected to the top outer wall of the large water tank via a bearing. The middle outer wall of the output shaft is fixedly connected to... The large water tank is equipped with a gear, the top of which meshes with a rack. A rectangular groove is formed on the top of the large water tank, and a slider is slidably connected to the inner wall of the rectangular groove. A U-shaped frame is fixedly connected to the top of the slider, and the side wall of the U-shaped frame is fixedly connected to the top side wall of the rack. A temperature measuring gun is fixedly connected to the top of the inner wall of the U-shaped frame, and a filter screen is fixedly connected to the inner wall of the large water tank. By setting up the temperature measuring component, it is convenient to realize real-time temperature measurement and detection of the molten steel inside the large water tank through the temperature measuring gun, so that the operator can observe the cooling of the molten steel in a timely manner.

[0007] Preferably, the temperature measuring component further includes a vertical plate fixedly connected to the top of the inner wall of the U-shaped frame. The bottom side wall of the vertical plate is rotatably connected to a rotating rod via a bearing. The outer wall of the rotating rod is fixedly connected to a toggle block. The toggle block is located above the filter screen. During the movement of the U-shaped frame, the vertical plate will move along with the rotating rod. During the movement of the rotating rod, the toggle block will move along with it, so that the toggle block will continuously agitate the molten steel during the movement, thereby effectively improving the cooling effect of the equipment on the molten steel.

[0008] Preferably, a cooling assembly is provided at the bottom of the large water tank. The cooling assembly includes a first water pipe connected to the bottom of the large water tank, a valve fixedly connected to the outer wall of one end of the first water pipe, and a cooling water tank connected to the other end of the first water pipe. A positioning frame is fixedly connected to the top outer wall of the cooling water tank, and the side wall of the positioning frame is fixedly connected to the outer wall of the mounting plate. A second water pipe is connected to the top right side of the cooling water tank, a cooling water pump is connected to the other end of the second water pipe, and a third water pipe is connected to the other side of the cooling water pump. The outer wall of the third water pipe is fixedly connected to the inner wall of the large water tank, and a cooling nozzle is connected to the other end of the third water pipe. The cooling nozzle is located inside the large water tank, and a temperature sensor is fixedly connected to the top inner wall of the large water tank. A wire is connected to the top of the sensor, and the other end of the wire is connected to the top outer wall of the cooling water pump. By setting up a cooling component, when molten steel needs to be cooled, after the molten steel is sampled and introduced into the large water tank, the operator starts the cooling water pump, which causes the cooling water pump to push the cold water inside the cooling water tank into the second and third water pipes, and then discharge it through the cooling nozzles. The cooling nozzles automatically spray atomized water, and the temperature sensor detects the temperature change of the molten steel in real time. The cooling water automatically shuts off after the temperature of the molten steel inside the large water tank drops below 50 degrees Celsius for five seconds. Some of the atomized water evaporates during cooling, and the remaining cooling water flows into the water tank for recycling after passing through the water tank filter and the pipe filter, reducing waste and thus achieving the cooling treatment of the molten steel inside the large water tank.

[0009] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixed at the four corners of the bottom of the mounting plate. By setting four support legs, it is easy to achieve a stable support for the mounting plate.

[0010] Preferably, the inner wall of the rectangular groove is adapted to the bottom outer wall of the slider, and the top of the slider is fixedly connected to the bottom of the U-shaped frame. By setting the rectangular groove and the slider, it is easy to make the slider slide inside the rectangular groove.

[0011] Preferably, there are two sliders, both of equal size, and both sliders are symmetrically distributed along the center plane of the large water tank.

[0012] Preferably, there are three actuating blocks, all of equal size, arranged in a linear array along the outer wall of the rotating rod.

[0013] Preferably, one end of the third water pipe is connected to the bottom left outer wall of the cooling water pump, and the bottom right outer wall of the cooling water pump is connected to one end of the second water pipe.

[0014] This invention provides a cooling device for a molten steel sampler. This cooling device for a molten steel sampler has the following advantages:

[0015] (1) The cooling device for this molten steel sampler, by setting up a temperature measuring component, requires intermittent temperature measurement of the interior of the large water tank when cooling of the molten steel is needed. First, the operator puts the molten steel into the large water tank. After the molten steel is put into the large water tank, it will pass through a filter screen to filter impurities. When it is necessary to measure the temperature of the molten steel, the operator starts the forward and reverse motor to cause the output shaft to rotate. During the rotation of the output shaft, the output shaft will rotate, causing the gear to rotate. After the gear rotates, it will mesh with the rack. At this time, through The rectangular groove limits the slider, causing the rack to move, which in turn moves the U-shaped frame. During the movement of the U-shaped frame, the operator can turn on the temperature gun to uniformly measure the temperature of the molten steel inside the large water tank, allowing the operator to observe the cooling status of the molten steel at any time. As the U-shaped frame moves, the vertical plate moves along with the rotating rod, which in turn moves the agitator block. The agitator block continuously moves the molten steel, effectively improving the cooling effect of the equipment.

[0016] (2) The cooling device of the molten steel sampler, by setting up a cooling component, when the molten steel needs to be cooled, after the molten steel is sampled and introduced into the interior of the large water tank, the operator starts the cooling water pump, which causes the cooling water pump to push the cold water inside the cooling water tank into the interior of the second and third water pipes, and discharges it through the cooling nozzles, so that the cooling nozzles automatically spray atomized water, and the temperature sensor detects the temperature change of the molten steel in real time. The cooling water is automatically shut off after the temperature of the molten steel inside the large water tank drops below 50 degrees Celsius for five seconds. Some of the atomized water will evaporate during cooling, and the remaining cooling water will flow into the water tank for recycling after passing through the water tank filter and the pipeline filter, reducing waste, thereby realizing the cooling treatment of the molten steel inside the large water tank.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] A preferred embodiment of the steel sampler cooling device provided by this utility model is, for example... Figures 1 to 4As shown: A cooling device for a molten steel sampler includes a mounting plate 1 and a temperature measuring component 31 disposed on the top of the mounting plate 1. The temperature measuring component 31 includes a large water tank 311 fixedly connected to the top of the mounting plate 1.

An output shaft 314 is fixedly connected to the output end of the forward and reverse motor 313. The other end of the output shaft 314 is rotatably connected to the outer wall of the top of the large water tank 311 via a bearing. A gear 315 is fixedly connected to the outer wall of the middle section of the 4. A rack 316 meshes with the top of the gear 315. A rectangular groove 317 is opened on the top of the large water tank 311. A slider 318 is slidably connected to the inner wall of the rectangular groove 317.

By setting the temperature measuring component 31... When molten steel needs cooling, the temperature inside the large water tank 311 needs to be measured periodically. First, the operator pours molten steel into the large water tank 311. After the molten steel is poured into the large water tank 311, it passes through a filter screen 3114 to filter impurities. When temperature measurement is required, the operator starts the forward / reverse motor 313, causing the output shaft 314 to rotate. During the rotation of the output shaft 314, the temperature inside the large water tank 311 is measured. The gear 315 is rotated, and after it rotates, it meshes with the rack 316. At this time, the rack 316 is moved by the limiting action of the slider 318 through the rectangular groove 317, which in turn causes the U-shaped frame 319 to move. During the movement of the U-shaped frame 319, the operator turns on the temperature measuring gun 3110 to uniformly measure the temperature of the molten steel inside the large water tank 311, so that the operator can observe the cooling status of the molten steel inside the large water tank 311 at any time.

[0024] The temperature measuring component 31 also includes a vertical plate 3111 fixedly connected to the top of the inner wall of the U-shaped frame 319. The bottom side wall of the vertical plate 3111 is rotatably connected to a rotating rod 3112 via a bearing. The outer wall of the rotating rod 3112 is fixedly connected to a toggle block 3113. The toggle block 3113 is located above the filter screen 3114. During the movement of the U-shaped frame 319, the vertical plate 3111 will move along with the rotating rod 3112. During the movement of the rotating rod 3112, the toggle block 3113 will move along with it. During the movement of the toggle block 3113, the toggle block 3113 will continuously move the molten steel, thereby effectively improving the cooling effect of the equipment on the molten steel.

[0025] A preferred embodiment of the steel sampler cooling device provided by this utility model is, for example... Figures 1 to 4As shown: A cooling assembly 32 is installed at the bottom of the large water tank 311. The cooling assembly 32 includes a first water pipe 321 connected to the bottom of the large water tank 311. A valve 322 is fixedly connected to the outer wall of one end of the first water pipe 321. A cooling water tank 323 is connected to the other end of the first water pipe 321. A positioning frame 324 is fixedly connected to the top outer wall of the cooling water tank 323. The side wall of the positioning frame 324 is fixedly connected to the outer wall of the mounting plate 1. A second water pipe 325 is connected to the top right side of the cooling water tank 323. A cooling water pump 326 is connected to the other end of the second water pipe 325. A third water pipe 327 is connected to the other side of the cooling water pump 326. The outer wall of the third water pipe 327 is fixedly connected to the inner wall of the large water tank 311. A cooling nozzle 328 is connected to the other end of the third water pipe 327. The cooling nozzle 328 is located inside the large water tank 311. A temperature sensor 329 is fixedly connected to the top inner wall of the large water tank 311. A wire 3210 is connected to the top of the sensor 329. The other end of the wire 3210 is connected to the top outer wall of the cooling water pump 326. By setting up the cooling component 32, when the molten steel needs to be cooled, after the molten steel is sampled and introduced into the large water tank 311, the operator starts the cooling water pump 326, which causes the cooling water pump 326 to introduce the cold water inside the cooling water tank 323 into the second water pipe 325 and the third water pipe 327, and discharge it through the cooling nozzle 328. The cooling nozzle 328 automatically sprays atomized water, and the temperature sensor 329 detects the temperature change of the molten steel in real time. The cooling water automatically shuts off after the temperature of the molten steel inside the large water tank 311 drops below 50 degrees Celsius for five seconds. Some of the atomized water evaporates during cooling, and the remaining cooling water flows into the water tank for recycling after passing through the water tank filter and the pipe filter, reducing waste and thus achieving the cooling treatment of the molten steel inside the large water tank 311.

[0026] Furthermore, the bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the four corners of the bottom of the mounting plate 1. By setting four support legs 2, it is easy to achieve stable support for the mounting plate 1.

[0027] Furthermore, the inner wall of the rectangular groove 317 is adapted to the bottom outer wall of the slider 318, and the top of the slider 318 is fixedly connected to the bottom of the U-shaped frame 319. By setting the rectangular groove 317 and the slider 318, it is easy to make the slider 318 slide inside the rectangular groove 317.

[0028] Furthermore, there are two sliders 318, both of equal size, and they are symmetrically distributed along the central face of the large water tank 311.

[0029] Furthermore, there are three toggle blocks 3113, all of equal size, arranged in a linear array along the outer wall of the rotating rod 3112.

[0030] In addition, one end of the third water pipe 327 is connected to the bottom left outer wall of the cooling water pump 326, and the bottom right outer wall of the cooling water pump 326 is connected to one end of the second water pipe 325.

[0031] Working Principle: When molten steel needs cooling, the temperature inside the large water tank 311 needs to be measured periodically. First, the operator pours molten steel into the large water tank 311. After the molten steel is poured into the large water tank 311, it passes through the filter screen 3114 to filter impurities. When the temperature of the molten steel needs to be measured, the operator starts the forward and reverse motor 313, causing the output shaft 314 to rotate. During the rotation of the output shaft 314, the gear 315 rotates. After the gear 315 rotates, it meshes with the rack 316. At this time, the slider 318 is limited by the rectangular groove 317. Under the action of the rack 316, the U-shaped frame 319 will move. During the movement of the U-shaped frame 319, the operator can turn on the temperature measuring gun 3110 to uniformly measure the temperature of the molten steel inside the large water tank 311. This allows the operator to observe the cooling status of the molten steel inside the large water tank 311 at any time. During the movement of the U-shaped frame 319, the vertical plate 3111 will move along with the rotating rod 3112. During the movement of the rotating rod 3112, the agitator block 3113 will move along with it. As the agitator block 3113 moves, it will continuously agitate the molten steel, thereby effectively improving the cooling effect of the equipment on the molten steel.

[0032] When molten steel needs to be cooled, after the molten steel is sampled and introduced into the large water tank 311, the operator starts the cooling water pump 326, which causes the cooling water pump 326 to push the cold water inside the cooling water tank 323 into the second water pipe 325 and the third water pipe 327, and discharge it through the cooling nozzle 328. The cooling nozzle 328 automatically sprays atomized water, and the temperature sensor 329 detects the temperature change of the molten steel in real time. The cooling water automatically shuts off after the temperature of the molten steel inside the large water tank 311 drops below 50 degrees Celsius for five seconds. Some of the atomized water evaporates during cooling, and the remaining cooling water flows into the water tank for recycling after passing through the water tank filter and the pipe filter, reducing waste and thus achieving the cooling treatment of the molten steel inside the large water tank 311.

Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this case.
