Description

Technical Field

[0001] This utility model relates to the field of descaling machine technology, and more specifically to a high-pressure water jet type steel rolling descaling machine. Background Technology

[0002] With the continuous development of steel rolling technology, various descaling technologies have emerged to improve the surface quality of steel and production efficiency. Among them, high-pressure water jet descaling machines are favored due to their advantages such as high efficiency, environmental friendliness, and ease of operation. This type of descaling machine uses a high-pressure pump to pressurize water to a certain pressure and sprays it onto the steel surface through nozzles, forming a high-speed water jet. This high-speed water jet has great impact and shearing force, which can quickly peel off the iron oxide scale on the steel surface and wash it away, thereby achieving the purpose of descaling.

[0003] As shown in the prior art published in CN218611054U, although this prior art, through its set-up box, inlet, outlet, first drive roller, second drive roller, first pulley, second pulley, first motor, fixed plate, high-pressure nozzle, water tank, and water pump, can quickly remove oxide scale from the surface of rolled steel and can also reuse the wastewater generated during the descaling process multiple times, effectively avoiding waste of water resources, the high-pressure nozzle in this prior art is fixed in position. This results in the steel billet's exterior, located between two adjacent high-pressure nozzles, not being effectively flushed, thus affecting the descaling effect on the steel billet. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a high-pressure water jet type steel rolling descaling machine. A first motor drives two first pulleys, which are driven by a first belt, to rotate. These two pulleys, through corresponding connecting shafts, drive a threaded rod to rotate. The threaded rod then drives a moving plate to adjust the position of the water tank laterally, facilitating a thorough rinsing of the steel billet by the high-pressure nozzle. Furthermore, the reciprocating motion continuously changes the impact angle of the water flow, allowing for easier rinsing of the four corners and removal of iron oxide scale. This achieves the effect of descaling the steel billet, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure water jet type steel rolling descaling machine, including a flushing component installed inside the housing for descaling steel billets;

[0006] The flushing component includes two threaded rods that are movably mounted inside the housing via bearings.

[0010] The conveying component includes two conveying rollers located inside the box. Support rollers are provided between the two conveying rollers and on the side of the two conveying rollers that are far apart from each other. Both ends of the support rollers and both ends of the conveying rollers are movably connected to the inner wall of the box via rotating shafts.

[0011] In a preferred embodiment, the exterior of the housing is provided with a power component for driving the transmission component to operate;

[0012] The power component includes two linkage shafts located outside the housing. Both linkage shafts pass through the housing and are fixed to the rotating shafts on the two conveyor rollers respectively. A second pulley is installed at the end of each linkage shaft away from the housing, and the two second pulleys are driven by a second belt.

[0013] A second motor is installed on the side of the housing away from the two linkage shafts. The output shaft of the second motor passes through the housing and is fixed together with the rotating shaft on one of the conveyor rollers.

[0014] In a preferred embodiment, a through hole is provided on one side of the box body, and the through hole extends into the mounting frame inside the box body. A filter plate is installed inside the bottom end of the mounting frame, and a bottom plate for connecting the box body is provided at both ends.

[0015] The bottom side of the box is fixedly connected to an inlet pipe and an outlet pipe. The inlet pipe is located at the top of the outlet pipe and at the bottom of the mounting frame.

[0016] In a preferred embodiment, a water supply pipe is fixedly connected to one side of the bottom of the tank, a water pump is installed outside the water supply pipe, and two branch pipes are fixedly connected to the top of the water supply pipe near the tank. Corrugated pipes are fixedly connected to the ends of the two branch pipes near the tank, and the ends of the corrugated pipes away from the branch pipes pass through the tank and are fixedly connected to the water tank.

[0017] In a preferred embodiment, a fixed scraper is installed on the front side of the water tank located inside the bottom of the tank body, and a movable scraper is provided on the front side of the water tank located inside the top of the tank body. Two spaced-apart assembly plates are installed on the front side of the water tank, and both ends of the movable scraper are movably connected to the two assembly plates respectively through a rotating shaft.

[0018] The top of the housing is equipped with a telescopic rod that is movably connected by a bearing.

[0024] 3. The telescopic nature of the telescopic rod ensures the connection between the movable scraper and the third motor, allowing the third motor to drive the telescopic rod to rotate the movable scraper. This enables the angle adjustment of the movable scraper, making it suitable for steel billets of different specifications and improving the practicality of this invention.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Refer to the instruction manual appendix Figure 1-6 This utility model provides a high-pressure water jet type steel rolling descaling machine, including a flushing component installed inside the housing 1 for descaling steel billets;

[0034] The flushing component includes two threaded rods 2 movably mounted inside the housing 1 via bearings. Each threaded rod 2 is externally threaded with a movable plate 3, and a water tank 4 is mounted on the side of each movable plate 3 that is far apart from the other. A high-pressure nozzle 5 is fixedly connected to the front end of each water tank 4 that is close to the other. The housing 1 is externally equipped with a driving component for driving the threaded rods 2. The driving component includes two connecting shafts 6 located outside the housing 1, both of which penetrate the housing 1 and are fixed to the two threaded rods 2 respectively. A first pulley 7 is mounted on the end of each connecting shaft 6 away from the housing 1, and the two first pulleys 7 are driven by a first belt 8. A first motor 31 is mounted on the top of the housing 1 on the side away from the first pulley 7. The output shaft of the first motor 31 penetrates the housing 1 and is fixed to one of the threaded rods 2.

[0035] In use, the first motor 31 drives the two first pulleys 7, which are driven by the first belt 8, to rotate. The two first pulleys 7 drive the threaded rods 2 to rotate through the corresponding connecting shafts 6, thereby driving the two threaded rods 2 to operate synchronously. The threaded rods 2 are provided with positioning posts 32 on their rear sides, and both ends of the positioning posts 32 are fixed to the inner wall of the box 1. The rear end of the moving plate 3 is sleeved on the outside of the positioning posts 32, so that the positioning posts 32 can limit the moving plate 3, thereby ensuring the stability of the moving plate 3 when it drives the water tank 4 to move laterally back and forth. During the back and forth movement of the water tank 4, the spray position of the high-pressure nozzle 5 can be adjusted, so that the high-pressure nozzle 5 can more comprehensively scour the surface of the steel billet. The back and forth movement can continuously change the impact angle of the water flow, thereby scour the four corners and more easily remove the iron oxide scale, thus achieving the effect of descaling the steel billet.

[0036] During descaling, water needs to be supplied to high-pressure nozzle 5 to flush the steel billet. Figure 1 and 5 As shown, a water supply pipe 23 is fixedly connected to one side of the bottom of the tank 1. A water pump 33 is installed outside the water supply pipe 23. Two branch pipes 24 are fixedly connected to the top of the water supply pipe 23 near the tank 1. Corrugated pipes 25 are fixedly connected to the ends of the two branch pipes 24 near the tank 1. The end of the corrugated pipe 25 away from the branch pipes 24 passes through the tank 1 and is fixedly connected to the water tank 4. The water pump 33 delivers water from the bottom of the tank 1 to the water supply pipe 23, and then delivers it to the two branch pipes 24. The two branch pipes 24 then deliver the water to the two water tanks 4 via the corresponding corrugated pipes 25. Then, the high-pressure nozzle 5 washes the outside of the steel billet to achieve descaling treatment. The corrugated pipes 25 can expand and contract with the movement of the water tanks 4 to ensure stable water delivery.

[0037] To more effectively remove iron oxide scale from the surface of the steel billet, it is necessary to reduce the adhesion between the iron oxide scale and the steel billet, such as... Figure 1 and 5As shown, a fixed scraper 26 is installed on the front side of the water tank 4 located inside the bottom of the box body 1, and a movable scraper 27 is provided on the front side of the water tank 4 located inside the top of the box body 1. Two spaced-apart assembly plates 28 are installed on the front side of the water tank 4, and both ends of the movable scraper 27 are movably connected to the two assembly plates 28 via rotating shafts. A telescopic rod 29 is installed inside the top of the box body 1, movably connected via bearings. The telescopic rod 29 passes through one of the assembly plates 28 and is fixed to the rotating shaft on the movable scraper 27. A third motor 30 is installed on the side of the box body 1 corresponding to the telescopic rod 29. The third motor 30 passes through the box body 1 and is fixed to the telescopic rod 29. The fixed scraper 26 connects to the bottom of the steel billet. The movable scraper 27 contacts the top of the steel billet. Since both the movable scraper 27 and the fixed scraper 26 are connected to the water tank 4, the fixed scraper 26 and the movable scraper 27 can reciprocate to clean the iron oxide scale adhering to the outside of the steel billet. This scrapes away the iron oxide scale, reducing the tightness between the iron oxide scale and the steel billet, thus facilitating the rinsing of the iron oxide scale for descaling. The telescopic rod 29 ensures that the movable scraper 27 is connected to the third motor 30, allowing the third motor 30 to drive the telescopic rod 29 to rotate the movable scraper 27, thereby achieving the effect of angle adjustment of the movable scraper 27. This allows the movable scraper 27 to be adapted to steel billets of different specifications, improving the practicality of this utility model.

[0038] During the descaling process described above, the steel billet needs to be transported into the box 1 first, such as... Figure 1 and 4As shown, the box body 1 has an inlet 9 and an outlet 10 at its front and rear ends, respectively. The inlet 9 is located in front of the outlet 10. The box body 1 contains a conveyor for transporting steel billets. The conveyor includes two conveying rollers 11 inside the box body 1. Support rollers 12 are provided between the two conveying rollers 11 and on the side away from each other. Both ends of the support rollers 12 and the two ends of the conveying rollers 11 are movably connected to the inner wall of the box body 1 via rotating shafts. The steel billets are transported into the box body 1 through the inlet 9 and supported and limited by the conveying rollers 11 and guide rollers inside the box body 1, thus ensuring the stability of the steel billet transport. The box body 1 is externally equipped with a power unit for driving the conveyor. The power unit includes two linkages located outside the box body 1. Shaft 13, two linkage shafts 13 both pass through housing 1 and are fixed to the rotating shafts on two conveyor rollers 11 respectively. The ends of the two linkage shafts 13 away from housing 1 are each equipped with a second pulley 14, and the two second pulleys 14 are driven by a second belt 15. A second motor 16 is installed on the side of housing 1 away from the two linkage shafts 13. The output shaft of the second motor 16 passes through housing 1 and is fixed to the rotating shaft on one of the conveyor rollers 11. When the second motor 16 drives the two second pulleys 14 driven by the second belt 15 to rotate, the two second pulleys 14 can drive the two conveyor rollers 11 to rotate through the corresponding linkage shafts 13. The steel billets are then transported by the conveyor rollers 11, which facilitates the transport of the steel billets for descaling treatment.

[0039] To facilitate the recycling of water resources, it is necessary to filter and collect water containing iron oxide scale, such as... Figure 1 and 6 As shown, a through hole 17 is provided on one side of the box body 1. The through hole 17 extends into the mounting frame 18 inside the box body 1. A filter plate 19 is installed inside the bottom of the mounting frame 18, and both ends of the bottom are provided with a base plate 20 for connecting the box body 1. A water inlet pipe 21 and a water outlet pipe 22 are fixedly connected to one side of the bottom of the box body 1. The water inlet pipe 21 is located at the top of the water outlet pipe 22 and at the bottom of the mounting frame 18. Water is transported to the bottom of the box body 1 through the water inlet pipe 21 and is positioned below the filter plate 19. The wastewater after rinsing the iron oxide scale is then filtered and collected by the filter plate 19. This allows the wastewater to be recycled, improving the efficiency of resource utilization. At the same time, the wastewater can be discharged through the water outlet pipe 22.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
