Description

Technical Field

[0001] This utility model relates to the field of rolling mill spraying, specifically to a rolling mill spraying device with an anti-splash mechanism. Background Technology

[0002] In steel rolling production, during hot rolling, the surface of steel billets or ingots is easily oxidized at high temperatures, forming iron oxide scale. If not removed, this scale will affect the quality of the steel plate and accelerate roll wear, requiring a high-pressure water spray system for descaling. During cold rolling, due to the high-speed rotation of the rolls, high friction, and large rolling forces, the rolls and steel plates are prone to high temperatures, leading to increased roll wear and even roll bursts. A spray system is also needed for cooling to ensure production and product quality. Whether it's high-pressure water descaling in hot rolling or cooling spraying in cold rolling, the high-speed sprayed liquid is prone to splashing everywhere after impacting the workpiece. The splashing high-pressure water and emulsion carry impurities such as iron filings, threatening operator safety, potentially entering electrical systems and causing short circuits, polluting the workshop environment, and increasing cleaning and maintenance costs. Therefore, there is a need for anti-splash devices.

[0003] Existing anti-splash spray systems for rolling mills have some problems. Some systems use an integrated anti-splash mechanism that is not suitable for older rolling mills without such a mechanism. In addition, some systems achieve this by adding a three-sided enclosed protective baffle to the existing rolling mill. This protective baffle is usually integrally formed and fixed in place at the anti-splash position. However, the current anti-splash devices have a relatively short service life relative to the rolling mill and need to be replaced regularly. Replacing these fixed devices is quite difficult. Utility Model Content

[0004] To solve the above-mentioned technical problems, a spraying device for a rolling mill with an anti-splash mechanism is provided. This technical solution solves the problems mentioned in the background art that the new device cannot be adapted to the old rolling mill without an anti-splash mechanism and that there are certain difficulties when the device needs to be replaced.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A steel rolling mill spraying device with a splash-proof mechanism includes a side plate and a top plate. A first boss is fixedly connected to the left side of the side plate. A connecting groove is provided at the upper and right ends of the side plate. Two symmetrically distributed second bosses are fixedly connected to the bottom of the top plate. A plurality of evenly distributed screw holes are provided through the front end of the first boss, the front end of the connecting groove, and the front and rear ends of the second bosses. The side plate and the top plate are connected by connecting screws.

[0007] Preferably, two sets of symmetrically distributed support frames are fixedly connected to both the front and rear ends of the side plate, with two support frames in each set. A hydraulic device is fixedly connected between the two support frames. A splash-proof curtain is provided at the front end of the side plate, and an observation window is provided at the right side of the splash-proof curtain at the front end of the side plate.

[0008] Preferably, the upper end of the top plate is fixedly connected to two sets of symmetrically arranged handles, and the upper end of the top plate is provided with a water pump, which is fixedly connected to the upper end of the top plate by connecting screws.

[0009] Preferably, the output end of the hydraulic device is fixedly connected to a movable wheel, and a foot pedal is provided at the outermost end of the support frame of the side plate that is far apart from each other.

[0010] Preferably, the output end of the water pump is fixedly connected to a spray pipe, the other end of the spray pipe passes through the upper end of the top plate and extends to the lower side of the top plate, an equal pressure valve is provided at the branch point of the spray pipe, spray nozzles are provided at several outlets of the spray pipe, and the spray pipe is fixedly connected to the top plate through reinforcing ribs on its outer surface.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: By using an externally mounted baffle device, this utility model eliminates the need to replace the entire rolling mill due to a lack of splash protection, allowing direct adaptation to existing rolling mills. Furthermore, its detachable and movable design allows for deployment on any part of the rolling mill requiring spraying, greatly increasing flexibility. The detachable and assembleable design also reduces the difficulty of replacement when needed. Additionally, the bottom is equipped with retractable casters, and the top has a handle for easy mechanical lifting, facilitating on-site assembly. Moreover, since the side and top plates of the splash protection device experience different levels of damage during use, with the top plate typically lasting longer, the detachable and assembleable design allows for replacement of only the side plates, saving costs.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figures 1-5 As shown, a steel rolling mill spray device with an anti-splash mechanism includes a side plate 1 and a top plate 2. A first boss 8 is fixedly connected to the left side of the side plate 1. Connecting grooves 14 are provided at the upper and right ends of the side plate 1. Two symmetrically distributed second bosses 16 are fixedly connected to the bottom of the top plate 2. Several evenly distributed screw holes 4 are provided through the front end of the first boss 8, the front end of the connecting groove 14, and the front and rear ends of the second bosses 16. The side plate 1 and the top plate 2 are connected by connecting screws 3. When using this device, the second bosses 16 at the bottom of the top plate 2 are inserted into the connecting grooves 14 at the upper end of the side plate 1 and the screw holes 4 at the corresponding positions are connected. Installing the connecting screw 3 completes the connection between the top plate 2 and the side plate 1, enabling the entire device to be disassembled and assembled. Furthermore, the cooperation between the first protrusion 8 on the left side of the side plate 1 and the connecting groove 14 on the right side of the other side plate 1 allows for flexibility in the coverage area of ​​the device. It can be installed at any length in the area of ​​the rolling mill where spraying is required, providing high flexibility in use. The combination of the two side plates 1 prevents liquid from splashing to both sides, achieving the anti-splash function of the device. In addition, the assemblable design of the side plate 1 and the top plate 2 allows for the replacement of all parts or only a part in the event of uneven damage, depending on the conditions.

[0021] Furthermore, two sets of symmetrically distributed support frames 13 are fixedly connected to both the front and rear ends of the side plate 1. Each set of support frames 13 consists of two frames, and a hydraulic device 10 is fixedly connected between the two support frames 13. A splash guard 15 is provided at the front end of the side plate 1, and an observation window 9 is provided on the right side of the splash guard 15 at the front end of the side plate 1. During the spraying process, the operation status of the steel and the rolling mill can be observed through the observation window 9. When the equipment stops, the operator can directly enter and exit through the splash guard, which is convenient for inspecting and maintaining the rolling mill. At the same time, the splash guard 15 is closely arranged to prevent liquid from splashing out from here during spraying. After the moving wheel 11 rises, the support frame 13 fixes the side plate when the moving wheel 11 has not descended.

[0022] Furthermore, two sets of symmetrically arranged handles 5 are fixedly connected to the upper end of the top plate 2, and a water pump 6 is installed at the upper end of the top plate 2. The water pump 6 is fixedly connected to the upper end of the top plate 2 by connecting screws 3. The water pump 6 installed at the top of the top plate 2 is also detachable. Considering the device situation, it can be confirmed whether to replace the entire plate or only the top plate. Liquid is drawn in through the input end of the water pump 6.

[0023] Furthermore, the output end of the hydraulic device 10 is fixedly connected to a movable wheel 11, and a foot pedal 12 is provided at the outermost end of the support frame 13 of the side plate 1. During assembly, the hydraulic device 10 at the bottom contains components such as a hydraulic lock, a hydraulic pump, a piston rod, and a lever structure. The foot pedal 12 is connected to the lever structure of the hydraulic device 10. The operator can control the piston rod of the hydraulic device 10 through the foot pedal 12 to push it, thereby controlling the raising and lowering of the inner and outer movable wheels 11. The left and right corresponding movable wheels 11 are controlled by the same foot pedal 12. After lowering to the position, the hydraulic lock in the hydraulic device 10 automatically locks. After stepping on the foot pedal 12 again, it unlocks, and the movable wheels 11 rise back for easy operation. After all the movable wheels 11 are lowered, the operator can easily push the device to any place where it needs to be deployed.

[0024] Furthermore, a spray pipe 7 is fixedly connected to the output end of the water pump 6. The other end of the spray pipe 7 passes through the upper end of the top plate 2 and extends to the lower side of the top plate 2. A pressure equalization valve 17 is provided at the branch point of the spray pipe 7. Spray nozzles 18 are provided at several outlets of the spray pipe 7. The spray pipe 7 is fixedly connected to the top plate 2 through reinforcing ribs 19 on its outer surface. The liquid pumped out by the output end of the water pump 6 enters the spray pipe 7 and is sprayed out from the spray nozzles 18, which can realize the spraying function of the device. Several reinforcing ribs 19 are provided on the spray pipe 7 under the top plate 2 to fix the spray pipe. A pressure equalization valve 17 is provided at the branch point of the spray pipe 7. Due to the spraying efficiency of the spray nozzles 18, the pressure of the liquid in the spray pipe 7 can be controlled to maintain a basically stable pressure, thus stabilizing the spraying efficiency of the spray nozzles 18.

[0025] Working principle: In use, the hydraulic device 10 lowers the moving wheels 11, pushing a set of side plates 1 to the installation location. Then, the foot pedal 12 controls the moving wheels to rise back, and the support frame 13 supports the side plates. After the set of side plates 1 is in place, with the help of certain mechanical equipment, the top plate 2 is lowered from above into the connecting grooves 14 at the upper end of the two side plates 1 and fixed with connecting screws 3. The coolant container on site is connected to the input end of the water pump 6 through a water pipe, and the equipment is fixed. When there are length requirements on site, the equipment can be assembled to a suitable length by cooperating with the first protrusions 8 of multiple side plates 1 and the connecting grooves 14.
