Description

Technical Field

[0001] The utility model relates to the technical field of steel billet processing, in particular to a steel billet water cooling and temperature reduction device. Background Art

[0002] With the rapid development of the steel industry, steel is used more widely. The billet cooling device is an auxiliary device used in the steel production process to cool the formed billet and reduce its temperature to facilitate subsequent processing. It has been widely used in the field of billet cooling.

[0003] Existing cooling and temperature reduction devices usually use nozzles to spray out of the cooling chamber to cool the steel billet, and the cooled water is directly discharged. However, this method consumes a lot of water and wastes water resources. At the same time, the existing nozzles have poor cooling effect on special-shaped steel billets and cannot spray evenly on the surface of the steel billet. During cooling, the temperature difference on the surface of the steel billet is large, the cooling effect is poor, and it also causes uneven stress inside the steel billet. Utility Model Content

[0004] In view of the shortcomings of large water consumption, poor cooling effect and influence on the internal structure of the steel billet during the cooling process of the steel billet, the utility model provides a steel billet water cooling and temperature reduction device which can improve the cooling effect of the steel billet and reduce the cooling water consumption.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A water cooling and temperature reduction device for steel billets includes a device body, a water vapor collection mechanism is provided on the top of the device body, a low-temperature water tank and a high-temperature water tank are provided on the bottom, and a plurality of conveying rollers are provided for rotation inside, wherein the low-temperature water tank and the high-temperature water tank are respectively provided with water pump 2 and water pump 1; two rotating spraying mechanisms are fixedly provided on the upper end of the high-temperature water tank, wherein the spray mechanism close to the low-temperature water tank is connected to water pump 2 in the low-temperature water tank through a pipeline, and the other spray mechanism is connected to water pump 1 in the high-temperature water tank through a pipeline; the water vapor collection mechanism is arranged above the spray mechanism, and the drain outlet is connected to the low-temperature water tank.

[0007] Furthermore, the spray mechanism includes a C-shaped hollow groove and a rotating nozzle component, wherein the two sides of the C-shaped hollow groove are fixedly connected to the two sides of the inside of the high-temperature water tank, and the bottom is connected to the pipeline; the upper and lower ends of the inner side of the C-shaped hollow groove are respectively rotatably installed with the rotating nozzle components. When in use, water is transported from the pipeline to the C-shaped hollow groove, and then dispersed to the nozzle assemblies at the upper and lower ends through the C-shaped hollow groove. The rotating nozzle assembly rotates to spray, thereby cooling the steel billet; the design of the C-shaped hollow groove and the rotating nozzle component significantly improves the cooling effect; the C-shaped hollow groove can ensure that the water flow is evenly distributed to the nozzle assemblies at the upper and lower ends, thereby enhancing the density and uniformity of the spray-formed water curtain, thereby covering a larger surface area of ​​the steel billet and improving the uniformity and efficiency of cooling. The rotating nozzle component rotates when spraying water, and can evenly spray steel billets of different shapes, with high flexibility.

[0008] Furthermore, the rotating spray head assembly includes a plurality of annular concave plates, a motor, and a chain; the annular concave plate is rotatably embedded in a C-shaped hollow groove, and an inner ring is fixedly mounted on the outer periphery of the annular concave plate, and a spray head is mounted at the bottom, wherein a ratchet 1 is rotatably mounted on the surface of the inner ring; the motor is fixedly mounted on the C-shaped hollow groove, and a ratchet 2 is fixedly mounted on the input shaft of the motor; the chain is connected to the outer periphery of ratchet 1 and ratchet 2. During use, the motor drives ratchet 2 to rotate, and ratchet 2 drives ratchet 1 to rotate through the chain. At this time, ratchet 1 drives the inner ring, the annular concave plate, and the spray head to rotate, rotating and spraying water to cool the steel billet; the motor-driven chain and ratchet system can ensure that the spray head rotates smoothly and continuously, so that the sprayed water can evenly cover the surface of the steel billet. This method not only improves cooling efficiency and reduces the risk of steel billet deformation caused by uneven cooling, but also reduces the need for manual operation, realizes automated control, and thereby improves production safety and efficiency.

[0009] Furthermore, the rotating spray head component also includes a thrust bearing, wherein the top of the thrust bearing is fixedly connected to the C-shaped hollow groove, and the bottom is fixedly connected to the inner ring. The provision of the thrust bearing strengthens the connection between the C-shaped hollow groove and the ratchet wheel, thereby improving the stability of use.

When in use, the air pump works, and the water vapor generated during the cooling process of the steel billet is sucked into the air pump through the cover, and then transported to the condenser through the pipe. The condenser condenses the water vapor into liquid water and then discharges it into the low-temperature water tank through the drain, completing the recycling of the water vapor. Through the coordinated use of the air pump and the condenser, the water vapor generated by the cooling process can be extracted and condensed in time, converted into liquid water and stored in the low-temperature water tank, and water resources are recycled, which reduces the water consumption in the cooling process and reduces the impact of wastewater discharge on the environment, meeting the requirements of environmental protection and energy conservation.

[0012] During use, the steel billet is transported to the spray mechanism through the conveyor roller. At this time, the water pump draws water from the high-temperature water tank into the spray mechanism, and the hot water is rotated and sprayed onto the surface of the steel billet through the spray mechanism to pre-cool the steel billet. After that, the steel billet moves to the spray mechanism close to the low-temperature water tank. At this time, the water pump transports the cooling water in the low-temperature water tank to the spray mechanism through the pipeline. The spray mechanism rotates and sprays the cooling water to thoroughly cool the steel billet. While the steel billet is cooling, the water vapor collection mechanism collects the water vapor evaporated during the cooling process, and returns it to the low-temperature water tank after condensation for circulation cooling.

[0013] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0014] 1.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: A water cooling and temperature reduction device for steel billets, comprising a device body 7, a water vapor collecting mechanism provided on the top of the device body 7, a low-temperature water tank 11 and a high-temperature water tank 9 provided on the bottom, and a plurality of conveying rollers 12 provided for rotation inside, wherein the low-temperature water tank 11 and the high-temperature water tank 9 are respectively provided with a water pump 2 10 and a water pump 1 8; two rotating spraying mechanisms 3 are fixedly provided on the upper end of the high-temperature water tank 9, wherein the spray mechanism 3 close to the low-temperature water tank 11 is connected to the water pump 2 10 in the low-temperature water tank 11 through a pipeline, and the other spray mechanism 3 is connected to the water pump 1 8 in the high-temperature water tank 9 through a pipeline; the water vapor collecting mechanism is arranged above the spray mechanism, and the drain outlet is connected to the low-temperature water tank 11.

[0025] Working principle:

[0026] During use, the steel billet is transported to the spray mechanism 3 through the conveying roller 12. At this time, the water pump 8 draws the water in the high-temperature water tank 9 into the spray mechanism 3, and the hot water is rotated and sprayed onto the surface of the steel billet through the spray mechanism 3 to pre-cool the steel billet. After that, the steel billet moves to the spray mechanism 3 close to the low-temperature water tank 11. At this time, the water pump 10 transports the cooling water in the low-temperature water tank 11 to the spray mechanism 3 through the pipeline. The spray mechanism 3 rotates and sprays the cooling water to thoroughly cool the steel billet. While the steel billet is cooling, the water vapor collection mechanism collects the water vapor evaporated during the cooling process, and condenses it back to the low-temperature water tank 11 for circulation cooling.

[0027] Example 2: Differences from Example 1 are that the spray mechanism 3 includes a C-shaped hollow groove 13 and a rotating nozzle assembly. The C-shaped hollow groove 13 is fixedly connected to the interior of the high-temperature water tank 9 on both sides, and the bottom is connected to a pipeline. Rotating nozzle assemblies are rotatably mounted at the upper and lower ends of the C-shaped hollow groove 13. During use, water is transported from the pipeline into the C-shaped hollow groove 13 and then dispersed through the C-shaped hollow groove 13 to the nozzle assemblies at the upper and lower ends. The rotating nozzle assemblies rotate to spray, thereby cooling the steel billet. The design of the C-shaped hollow groove 13 and the rotating nozzle assembly significantly improves the cooling effect. The C-shaped hollow groove 13 ensures that the water flow is evenly distributed to the nozzle assemblies at the upper and lower ends, enhancing the density and uniformity of the sprayed water curtain, thereby covering a larger surface area of ​​the steel billet and improving the uniformity and efficiency of cooling. The rotating nozzle assembly rotates while spraying water, allowing for uniform spraying of steel billets of different shapes, providing high flexibility.

[0028] The water vapor collection mechanism includes a condenser 1, an air pump 2 and a cover 4, wherein the condenser 1 and the air pump 2 are both fixedly mounted on the device body 7; the air inlet of the air pump 2 is connected to the cover 4 through a pipe, and the air outlet is connected to the inlet of the condenser 1 through a pipe, wherein the cover 4 is arranged above the spray mechanism 3; the drain outlet of the condenser 1 is connected to the low-temperature water tank 11 through a pipe. When in use, the air pump 2 works, and the water vapor generated during the cooling process of the steel billet is sucked into the air pump 2 through the cover 4, and then transported to the condenser 1 through the pipe. The condenser 1 condenses the water vapor into liquid water and then discharges it into the low-temperature water tank 11 through the drain outlet, completing the recycling of the water vapor. Through the coordinated use of the air pump 2 and the condenser 1, the water vapor generated by the cooling process can be extracted and condensed in time, converted into liquid water and stored in the low-temperature water tank 11, and water resources are recycled, which reduces the water consumption in the cooling process and reduces the impact of wastewater discharge on the environment, meeting the requirements of environmental protection and energy saving.

[0029] Example 3: The difference from Example 2 is that the rotating nozzle component includes several annular concave plates 14, a motor 20 and a chain; the annular concave plate 14 is rotatably embedded in the C-shaped hollow groove 13, and the outer periphery of the annular concave plate 14 is fixedly sleeved with an inner sleeve 17, and a spray head 18 is installed at the bottom, wherein a ratchet 16 is rotatably mounted on the surface of the inner sleeve 17; the motor 20 is fixedly mounted on the C-shaped hollow groove 13, and a ratchet 2 19 is fixedly mounted on the input shaft of the motor 20; the chain is sleeved and connected to the outer periphery of the ratchet 16 and the ratchet 2 19. During use, the motor 20 drives the ratchet 2 19 to rotate, and the ratchet 2 19 drives the ratchet 1 16 to rotate through the chain. At this time, the ratchet 16 drives the inner ring 17, the annular concave plate 14 and the spray head 18 to rotate, and the water is rotated and sprayed out to cool the steel billet. The chain and ratchet system driven by the motor 20 can ensure that the spray head 18 rotates smoothly and continuously, so that the sprayed water can evenly cover the surface of the steel billet. This method not only improves the cooling efficiency and reduces the risk of steel billet deformation caused by uneven cooling, but also reduces the need for manual operation, realizes automatic control, and thus improves the safety and efficiency of production.

[0030] The rotating nozzle assembly further includes a thrust bearing 15, wherein the top of the thrust bearing 15 is fixedly connected to the C-shaped hollow groove 13, and the bottom is fixedly connected to the inner collar 17. The provision of the thrust bearing 15 strengthens the connection between the C-shaped hollow groove 13 and the ratchet 16, thereby improving the stability of use.
