Description

Technical Field

[0001] This utility model relates to the field of round steel cooling technology, and in particular to a slow cooling device for round steel cooling. Background Technology

[0002] Currently, round steel bars need to be heated before piercing. After being heated to a certain degree, the round steel bars are pierced. After the round steel bars are pierced, they need to be cooled. The existing cooling tanks for cooling round steel bars include a tank body containing coolant. When the round steel bars need to be cooled, they are placed in the coolant in the tank body to cool them.

[0003] The currently published patent, CN213866325U, discloses a cooling device for round steel processing and forming. Through the arrangement of a threaded rod, a slider, a water tank, a water pipe, and a nozzle, it can ensure sufficient cooling. The threaded rod can move the slider left and right, thereby allowing the nozzle to rinse the placement platform from all directions, so that the surface of the steel is fully sprayed with cooling water, greatly improving the cooling efficiency and making the steel forming effect more significant.

[0004] Based on the above findings, although the threaded rod allows the slider to move left and right during use, enabling the nozzles to thoroughly rinse the placement platform and ensure that the steel surface is fully sprayed with cooling water, thus achieving the cooling effect on the round steel, after the round steel has cooled, the workers must first remove it from the device and then place a new round steel inside to continue the cooling process. The workers cannot perform cooling operations during the removal and placement of the round steel, thus hindering continuous cooling. This not only reduces the cooling speed of the round steel but also increases the workload of the workers. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a slow cooling device for round steel, which can solve the problem that workers cannot perform cooling operations during the process of removing and placing round steel, thus making it impossible to continuously cool the round steel, which not only reduces the cooling speed of the round steel, but also increases the labor intensity of the workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slow cooling device for round steel, comprising a cooling box and a round steel cooling device; the round steel cooling device includes a water spray pipe, a sliding sleeve, a telescopic sliding rod, an electric telescopic rod, a water pump, a water pumping pipe, a drain pipe, and a slag storage box. The water spray pipe is rotatably installed inside the cooling box, with both its front and rear ends extending to the outside of the cooling box. The sliding sleeve is fixedly connected to the rear end of the water spray pipe. The telescopic sliding rod is slidably fitted inside the sliding sleeve. The electric telescopic rod is fixedly installed on the rear side of the cooling box, with its left end rotatably installed at the output end of the electric telescopic rod. The water pump is fixedly installed on the front side of the cooling box, with the water pumping pipe fixedly installed at the inlet end of the water pump. The end of the water pump away from the water pump extends into the interior of the cooling box.

[0007] Preferably, the cooling box has a feed inlet on the left side and a discharge outlet on the right side.

[0008] Preferably, a conveyor belt is installed inside the cooling box, and the surface of the conveyor belt is evenly provided with drainage holes.

[0009] Preferably, a filter screen is fixedly connected inside the cooling box, and an L-shaped scraper is slidably installed inside the cooling box, with the bottom of the L-shaped scraper contacting the top of the filter screen.

[0010] Preferably, the rear end of the L-shaped scraper is threadedly connected to a threaded rod, and a bidirectional motor is fixedly installed on the rear side of the cooling box, with the output end of the bidirectional motor fixedly connected to the left end of the threaded rod.

[0011] Preferably, the lower end of the drain pipe is fixedly installed at the drain end of the water pump, and the upper end of the drain pipe is rotatably installed at the front end of the spray pipe.

[0012] Preferably, the slag storage box is slidably mounted on the right side of the cooling box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This slow cooling device for round steel bars allows the conveyor belt to gradually move the round steel bars to the right and remove them from the cooling box through the discharge port after the round steel bars have cooled. The workers only need to place the round steel bars on the left end of the conveyor belt, and the conveyor belt can automatically move the round steel bars into and out of the cooling box, thus continuously cooling the round steel bars. This not only increases the cooling speed of the round steel bars but also reduces the labor intensity of the workers. Attached Figure Description

[0025] Please see Figure 1-4This utility model provides a technical solution: a slow cooling device for round steel cooling, including a cooling box 1 and a round steel cooling device. The cooling box 1 has an inlet 2 on the left side and an outlet 3 on the right side. A conveyor belt 4 is installed inside the cooling box 1. The surface of the conveyor belt 4 is evenly provided with drainage holes 5. A filter screen 6 is fixedly connected inside the cooling box 1. An L-shaped scraper 7 is slidably installed inside the cooling box 1. The bottom of the L-shaped scraper 7 contacts the top of the filter screen 6. A threaded rod 8 is threadedly connected to the rear end of the L-shaped scraper 7. A drive motor 9 is fixedly installed on the rear side of the cooling box 1. The output end of the drive motor 9 is fixedly connected to the left end of the threaded rod 8.

[0026] The round steel cooling device includes a water spray pipe 10, a sliding sleeve 11, a telescopic sliding rod 12, an electric telescopic rod 13, a water pump 14, a water pumping pipe 15, a drain pipe 16, and a slag storage box 17. The water spray pipe 10 is rotatably installed inside the cooling box 1, and both the front and rear ends of the water spray pipe 10 extend to the outside of the cooling box 1. The sliding sleeve 11 is fixedly connected to the rear end of the water spray pipe 10. The telescopic sliding rod 12 is slidably sleeved inside the sliding sleeve 11. The electric telescopic rod 13 is fixedly installed on the rear side of the cooling box 1, and the left end of the telescopic sliding rod 12 is rotatably installed on the output end of the electric telescopic rod 13. The water pump 14 is fixedly installed on the front side of the cooling box 1, and the water pumping pipe 15 is fixedly installed on the inlet end of the water pump 14. The end of the water pumping pipe 15 away from the water pump 14 extends into the interior of the cooling box 1. The lower end of the drain pipe 16 is fixedly installed on the drain end of the water pump 14, and the upper end of the drain pipe 16 is rotatably installed on the front end of the water spray pipe 10. The slag storage box 17 is slidably installed on the right side of the cooling box 1.

[0027] After the operator starts the conveyor belt 4, the round steel is placed at the left end of the conveyor belt 4. The conveyor belt 4 rotates and drives the round steel to gradually move to the right and enter the cooling box 1 through the feed inlet 2. After the operator starts the water pump 14, the water pump 14 can draw water stored in the cooling box 1 through the water pumping pipe 15 and discharge it into the spray pipe 10 through the drain pipe 16. The water is discharged onto the surface of the round steel through the spray pipe 10 for cooling treatment. After the operator starts the electric telescopic rod 13, the output end of the electric telescopic rod 13 slides left and right, which drives the telescopic slide rod 12 to slide left and right. The telescopic slide rod 12 slides left and right, which drives the sliding sleeve 11 to swing left and right. The telescopic slide rod 12 can slide inside the sliding sleeve 11. When the sleeve 11 swings left and right, it drives the water spray pipe 10 to rotate alternately clockwise and counterclockwise. The rotation of the water spray pipe 10 can increase the spray range and make the water flow sprayed obliquely on the surface of the round steel, which improves the uniformity of water spraying on the surface of the round steel and thus improves the cooling quality of the round steel. After the round steel is cooled, the conveyor belt 4 can drive the round steel to gradually move to the right and remove it from the interior of the cooling box 1 through the discharge port 3. The staff only needs to place the round steel on the left end of the conveyor belt 4, and the conveyor belt 4 can automatically carry the round steel into the interior of the cooling box 1 and remove it, thus continuously cooling the round steel. This not only improves the cooling speed of the round steel, but also reduces the labor intensity of the staff.

[0028] Wastewater used for cooling round steel bars can fall through the drainage hole 5 onto the surface of the filter screen 6. During cooling, the round steel bars produce debris. The filter screen 6 filters out this debris from the wastewater. The filtered wastewater then falls by gravity into the cooling tank 1 for reuse. When there is a large amount of debris on the surface of the filter screen 6, the operator starts the drive motor 9. The output of the drive motor 9 rotates, which in turn rotates the threaded rod 8. The rotation of the threaded rod 8 causes the L-shaped scraper 7 to gradually move to the right. The L-shaped scraper 7 slides to the right, scraping the debris from the surface of the filter screen 6 to the right position and causing it to fall into the debris storage box 17. The debris is collected in the debris storage box 17, improving the convenience of debris handling for the operator.
