Description

Technical Field

[0001] This utility model relates to the field of rebar production technology, and in particular to a high-efficiency cooling device for rebar production. Background Technology

[0002] As an indispensable structural material in the construction industry, the cooling process during the production of rebar directly affects the final performance of the product. Cooling is not only a necessary step in the production process but also crucial for improving steel quality. The primary purpose of cooling in rebar production is to improve its mechanical properties. By controlling the cooling rate and temperature, the metallographic structure of the steel can be significantly optimized.

[0003] Most existing cooling devices involve spraying water or directly immersing the rebar in water. While the surface of the rebar cools rapidly, the interior remains uncooled, resulting in a significant temperature difference that can cause stress. Furthermore, the irregular shape of the rebar surface prevents the delivery pipe from fully adhering to the rebar, leading to water leakage. To overcome these drawbacks, this invention provides a highly efficient cooling device for rebar production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency cooling device for the production of rebar.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a partition component is provided inside the cooling box; a second conveying port is provided on both sides of the outside of the cooling box; a conveying pipe is fixedly connected to the second conveying port; a return port is provided on both sides of the outside of the cooling box and below the second conveying port; a return component is provided on the return port; several support frames are fixedly connected to the bottom inside the cooling box; conveying rollers are rotatably connected to the support frames; a heating component is provided on one side of the outside of the cooling box; a water inlet and drainage component is provided on one side of the outside of the cooling box; a protective door is hinged to the top of the cooling box; and an observation component is provided on the protective door.

[0006] Furthermore, the partition assembly includes several partitions fixedly connected to the interior of the cooling tank, the partitions having a first conveying port and water holes.

[0007] Furthermore, the reflux assembly includes a first water pipe fixedly connected to the reflux port, one end of the first water pipe being fixedly connected to the delivery pipe, and a booster pump being fixedly connected to the first water pipe.

[0008] Furthermore, the heating assembly includes a controller fixedly connected to the outside of the cooling box, the controller having a power port fixedly mounted on it, a heating plate fixedly connected to the bottom inside the cooling box, the power supply end of the heating plate being fixedly connected between the cooling box and the controller, a temperature sensor fixedly connected to the outside of the cooling box and above the controller, the inspection end of the temperature sensor being located inside the cooling box, and the temperature sensor being electrically connected to the controller.

[0009] Furthermore, the water inlet and drainage assembly includes a water inlet located on the outside of the cooling box, a third water pipe fixedly connected to the water inlet, a second valve fixedly connected to the third water pipe, a drain outlet located on the outside of the cooling box, a second water pipe fixedly connected to the drain outlet, and a first valve fixedly connected to the second water pipe.

[0010] Furthermore, the observation component includes an observation port opened on the protective door, and a glass is fixedly connected to the observation port.

[0011] The beneficial effects of this utility model are:

[0012] When using this utility model,

[0013] 1. The cooling box is divided into multiple spaces by partitions, and heating components are used to achieve different water temperatures in each space, thereby cooling the rebar in sections. This avoids the large temperature difference between the inside and surface of the rebar due to the surface temperature of the rebar dropping too quickly, which would increase the stress of the rebar.

[0014] 2. The water flowing out of the inlet and outlet of the rebar is returned to the cooling tank through the reflux assembly to prevent the cooling water from flowing out of the inlet and outlet. Attached Figure Description

The second conveying port 7 is fixedly connected to the second conveying port 7. The cooling box 1 has a return port 8 on both sides outside and below the second conveying port 7. The return port 8 is equipped with a return component. The bottom of the cooling box 1 is fixedly connected to several support frames 5. The support frames 5 are rotatably connected to the conveying rollers 6. The cooling box 1 has a heating component on one side outside. The cooling box 1 has a water inlet and drainage component on one side outside. The cooling box 1 has a protective door 22 hinged to the top. The protective door 22 is equipped with an observation component.

[0024] As shown in the figure, the partition assembly includes several partitions 2 that are fixedly connected to the interior of the cooling box 1. The partitions 2 have a first conveying port 4 and water holes 3, which are used to divide the cooling box 1 into multiple spaces.

[0025] As shown in the figure, the reflux assembly includes a first water pipe 10 fixedly connected to the reflux port 8. One end of the first water pipe 10 is fixedly connected to the delivery pipe 9. A booster pump 11 is fixedly connected to the first water pipe 10 to prevent cooling water from flowing out of the delivery pipe 9.

[0026] As shown in the figure, the heating assembly includes a controller 18 fixedly connected to the outside of the cooling box 1. A power port 19 is fixedly mounted on the controller 18. A heating plate 20 is fixedly connected to the bottom of the inside of the cooling box 1. The power supply end of the heating plate 20 passes through the cooling box 1 and is fixedly connected between the controller 18. A temperature sensor 21 is fixedly connected to the outside of the cooling box 1 and above the controller 18. The inspection end of the temperature sensor 21 passes through the cooling box 1 and is located inside the cooling box 1. The temperature sensor 21 is electrically connected to the controller 18 and is used to heat the cooling water in the overflow space of the cooling box 1.

[0027] As shown in the figure, the water inlet and drainage assembly includes a water inlet 15 on the outside of the cooling box 1, a third water pipe 16 fixedly connected to the water inlet 15, a second valve 17 fixedly connected to the third water pipe 16, a drain outlet 12 on the outside of the cooling box 1, a second water pipe 13 fixedly connected to the drain outlet 12, and a first valve 14 fixedly connected to the second water pipe 13 for cooling water to flow into and out of the cooling box 1.

[0029] Working principle: Before use, first check that the entire device is intact. After inspection, open the first valve 14 and the second valve 17. Then connect the external water source to the third water pipe 16. The external water flows through the third water pipe 16 into one side of the cooling tank 1, and then through the water hole 3 and partition 2 to other spaces. When the cooling tank 1 is full of cooling water, it is discharged through the second water pipe 13 on the drain outlet 12. Then connect the power port 19 to an external power source. The controller 18 controls the heating plate 20 (model HC510-OC-230-16-I) to cool the water. The water is used for heating. When the PT100 temperature sensor 21 detects that the temperature has reached the appropriate level, the controller 18 cuts off the power to the heating plate 20. Then, the rebar that needs to be cooled is sent from the conveying pipe 9 into the cooling box 1, passes through the first conveying port 4 on the partition 2, and then exits from the conveying pipe 9 at the other end of the cooling box 1 to cool it. During the cooling process, cooling water will flow out from the inlet and outlet on both sides of the cooling box 1. At this time, the booster pump 11 is started to draw the cooling water flowing into the conveying pipe 9 into the first water pipe 10, and then returns it to the cooling box 1 through the return port 8.
