Description

Technical Field

[0001] This invention relates to the field of roll manufacturing and processing technology, specifically to a roll spray quenching treatment device. Background Technology

[0002] In industrial production, rolling mill rolls are crucial equipment components widely used in metallurgy, papermaking, and plastics industries, and their performance directly impacts product quality and production efficiency. Quenching is a vital step in improving the hardness, wear resistance, and service life of rolling mill rolls. However, existing quenching equipment presents several problems that urgently need to be addressed.

[0003] During the quenching process, an oxide layer or decarburized layer forms on the surface of the rolls. If these surface impurities are not cleaned in time, they will seriously affect the performance of the rolls and the effect of subsequent processing. However, existing quenching equipment lacks an effective cleaning mechanism, requiring additional steps to clean surface impurities, which not only increases production costs but also reduces production efficiency.

[0004] To address the above problems, this invention proposes a roll spray quenching treatment device. Summary of the Invention

[0019] Preferably, the recycling component includes a water collection section, the upper surface of which is fixedly connected to the middle of the arc-shaped chassis. A connecting pipe is provided through the middle of the water collection section. A screw pump is fixedly connected to the output end of the connecting pipe.

[0021] Preferably, a maintenance box is fixedly connected to the outer wall of the cylinder, and a maintenance door is provided on the outer wall of the maintenance box. The exterior of the water purifier is located inside the maintenance box.

[0022] Preferably, a base is fixedly connected to the bottom of the cylinder, and a connector is fixedly connected to the outer wall of the liquid separator.

[0023] Preferably, the rotating component and the limiting component are located on the same vertical line.

[0024] The spray quenching coolant recycling and control system includes:

[0025] A temperature sensor, installed inside the separator, is used to detect the temperature of the coolant and the recovery fluid in the pipe.

[0026] PLC is used for overall control and coordination of system operation;

[0027] HMI is used by operators to monitor and adjust system parameters;

[0028] The temperature controller, located inside the separator, is used to regulate the temperature of the mixture of the recovered liquid and the coolant.

[0029] Working Principle: When performing spray quenching on the rolls, auxiliary equipment is first used to place the rolls inside the cylinder, ensuring the bottom contacts the top of the support. Then, two sets of electric push rods are activated, controlling the arc-shaped clamps on both sides to clamp and fix the rolls to their outer wall. Next, a sealing cap is placed on top of the cylinder, causing multiple movable clamps at the bottom to slide along the top outer wall of the roll. Simultaneously, the moving rod moves in the middle of the limit ring, compressing the spring and generating a rebound force that pushes the multiple movable clamps to clamp and fix the rolls to their outer wall. This ensures the rolls to be quenched are stably positioned inside the device. The device is then started to begin spray quenching. The connector is connected to an external coolant storage and delivery system. Coolant enters the distributor pipe, flows through the distributor into two annular pipes, and then through multiple connecting pipes. Multiple sprayers are inserted into the rollers and sprayed onto them. Simultaneously, multiple electric push rods are activated, controlling the slide to move up and down along the outer wall of the first limiting rod. This drives the adjusting rod to control the movement of the support rod, bringing the cleaning brushes closer to the outer wall of the rollers. As the cleaning brushes move, the movable rod is adjusted, gradually increasing the angle between it and the inner wall of the cylinder. This causes the movable seat to slide down along the outer wall of the second limiting rod, which in turn stretches the first spring, generating a rebound reaction force. At this point, multiple cleaning brushes come into contact with the outer wall of the rollers, and multiple sprayers simultaneously perform spray quenching treatment on the outer wall of the rollers. The synchronous motor starts and controls the rotation of the support through the rotating shaft, which in turn drives the upper fixed roller to rotate, cleaning away the oxide layer or decarburized layer formed on its surface. At the same time, the sprayers can uniformly perform spray quenching treatment on the rollers. As the continuous spray quenching process continues, the wastewater containing impurities flows into the water collection unit. Driven by a screw pump, it enters the water purifier through a conduit. After purification by the purifier, it flows into the distribution pipe for use, while dirt and other impurities are discharged through the drain pipe. When the treated recycled liquid is put into use, the spray quenching coolant reuse control system used in conjunction with this invention drives the process. The treated wastewater enters the distribution pipe through the conduit and mixes with the coolant at the mixing point. An internal temperature sensor monitors the temperature of the mixture in real time. Based on the feedback data from the temperature sensor, the PLC automatically adjusts the liquid delivery rate through a temperature controller to ensure the temperature of the mixture remains within the set range. If the mixture temperature is too high, the PLC reduces the wastewater flow or increases the coolant flow to lower the temperature; if the mixture temperature is too low, the PLC increases the wastewater flow or decreases the coolant flow to raise the temperature. Operators monitor the system's operating status and adjust settings such as temperature limits and flow ratios through the HMI interface. The system operates automatically, ensuring that the temperature of the mixture is maintained within the set range to meet the requirements of spray quenching. The coolant at the appropriate temperature flows into two annular pipes, and through multiple sets of connecting pipes, flows into the corresponding sprayers, which then spray the rolls for quenching.

[0030] This invention provides a spray quenching treatment device for rolling mill rolls. It has the following beneficial effects:

[0031] 1. The present invention, through the combined action of the rotating component and the limiting component, ensures the uniformity of quenching during the spray quenching process of the roll, thereby optimizing the quenching effect, improving the surface quality of the roll, and avoiding the problems of local overheating or undercooling.

[0032] 2. The present invention, through the design of the cleaning component, enables it to automatically adapt to different types of rolls during the spray quenching process, and can clean the oxide layer or decarburized layer formed on the surface of the rolls. This can significantly improve the cooling effect, surface quality, stress distribution and mechanical properties, while reducing the need for subsequent processing and improving the level of automation.

[0033] 3. This invention uses a recycling component to recycle wastewater after use, which solves the problems of coolant waste, environmental pollution and unstable coolant temperature, thereby achieving the goals of resource reuse, reducing production costs and improving quenching effect.

[0034] 4. The spray quenching coolant recycling and control system designed in this invention, used in conjunction with the recycling component, solves the problems of coolant waste, environmental pollution, and unstable coolant temperature, thereby achieving the goals of resource reuse, reducing production costs, and improving quenching effect.

Detailed Implementation

[0047] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] Example:

[0049] Please see the appendix Figure 1 -Appendix Figure 3 and attached Figure 8 This invention provides a roll spray quenching treatment device, comprising:

[0050] Cylinder 1, which serves as the basic installation component of the overall device, is used to install and assemble various supporting operating mechanisms and their associated structural components;

[0051] The cleaning mechanism, which is located inside the cylinder 1, is used to clean the oxide layer or decarburized layer formed on the surface of the rolls during the high-temperature quenching process.

[0052] An arc-shaped base 25 is fixedly connected to the lower surface of the cylinder 1 and is used to collect wastewater generated during the quenching process.

[0053] A rotating assembly, located in the center of the arc-shaped chassis 25, is used to drive the rolls to rotate during the quenching process;

[0054] Includes a rotating shaft 16, the outer wall of which is rotatably connected to the middle of the arc-shaped chassis 25. A motor 15 is fixedly connected to the bottom end of the rotating shaft 16, and a support 17 is fixedly connected to the top end of the rotating shaft 16. Two electric push rods 18 are fixedly connected to both sides of the upper surface of the support 17, and arc-shaped clamps 19 are fixedly connected to the drive ends of the two sets of electric push rods 18.

[0055] Specifically, during the spray quenching treatment of the roll, the roll can be placed inside the cylinder 1 using auxiliary equipment, with its bottom contacting the top of the support 17. Then, two sets of electric push rods 18 are activated to control the arc-shaped clamps 19 on both sides to clamp and fix the roll to its outer wall. At this point, the pre-fixation of the roll is completed. Then, the sealing cover 20 is closed, and the limiting component limits the upper part. During the spray quenching treatment, the roll is controlled to rotate inside the device. By starting the motor 15, the rotating shaft 16 is driven to rotate, which in turn drives the support 17 to rotate synchronously. Under the rotation of the support 17, the roll clamped at the top rotates synchronously. Thus, under the action of its rotation, it can be evenly subjected to the cooling liquid mist generated by the sprayer 37, ensuring the uniformity of quenching, thereby achieving the purpose of optimizing the quenching effect, improving the surface quality of the roll, avoiding the problem of local overheating or overcooling, and being cleaned by the cleaning brush 8.

[0056] A sealing cap 20 is disposed on the upper surface of the cylinder 1 and is used to seal the top of the cylinder 1 during the quenching process;

[0057] A limiting component, which is disposed on the lower surface of the sealing cover 20, is used to provide stability for the rotating roll;

[0058] The recycling component, located on the outer wall of cylinder 1, is used to recycle and reuse the wastewater generated during the quenching process.

[0059] Please see the appendix Figure 2 -Appendix Figure 5 The cleaning mechanism includes a control component, a resistance component, and a cleaning brush 8. The control component is used to control the cleaning brush 8 to make close contact with the outer wall of different types of rolls, and the resistance component is used to ensure the stability of the contact between the cleaning brush 8 and the outer wall of the roll.

[0060] The control component includes multiple mounting slots 2, each of which is located on the inner wall of the cylinder 1. Each mounting slot 2 is fixedly connected to a limiting rod 3. Each limiting rod 3 has a sliding seat 4 slidably connected to its outer wall. An adjusting rod 5 is rotatably connected to the outer wall of the sliding seat 4. Multiple mounting bases 6 are fixedly connected to the inner wall of the cylinder 1. Each mounting base 6 has a support rod 7 rotatably connected to its middle. The other end of the adjusting rod 5 is rotatably connected to the outer wall of the support rod 7. The other end of the support rod 7 is rotatably connected to the outer wall of the cleaning brush 8.

[0061] The resistance component includes a movable rod 9, one end of which is rotatably connected to the inner wall of the cylinder 1, and the other end of which is rotatably connected to a movable seat 14. The outer wall of the cleaning brush 8 has a second mounting groove 11, and a second limiting rod 12 is fixedly connected inside the second mounting groove 11. A first spring 13 is sleeved on the outside of the second limiting rod 12. One end of the first spring 13 is fixedly connected to the inner wall of the second mounting groove 11, and the other end of the first spring 13 is fixedly connected to the outer wall of the movable seat 14. The middle part of the movable seat 14 is slidably connected to the outer wall of the second limiting rod 12.

[0062] Specifically, multiple electric push rods 10 are activated, controlling the slide 4 to move up and down along the outer wall of the limiting rod 3. This drives the adjusting rod 5 to control the support rod 7, bringing the cleaning brush 8 closer to the outer wall of the roll. As the cleaning brush 8 moves, the movable rod 9 is adjusted, gradually increasing the angle between it and the inner wall of the cylinder 1. This causes the moving seat 14 to slide downwards along the outer wall of the limiting rod 12, which in turn stretches the spring 13, generating a rebound force. At this point, the multiple cleaning brushes 8 come into contact with the outer wall of the roll. In this way, the cleaning brush 8 can be controlled to contact the outer wall of different types of rolls through the control component. At the same time, under the control of the rotation component to rotate the roll, the oxide layer or decarburized layer formed on the roll surface can be automatically cleaned, significantly improving the cooling effect, surface quality, stress distribution, and mechanical properties, while reducing the need for subsequent processing and improving the level of automation.

[0063] Please see the appendix Figure 9 -Appendix Figure 10 The limiting component includes a limiting ring 21. The outer wall of the limiting ring 21 is fixedly connected to the lower surface of the sealing cover 20. Multiple moving rods 22 are slidably connected to the middle of the limiting ring 21. Each end of the multiple moving rods 22 is fixedly connected to a movable clamp 24. A second spring 23 is fixedly connected between each movable clamp 24 and the limiting ring 21. The middle part of the second spring 23 is sleeved on the outside of the moving rod 22.

[0064] Specifically, after the bottom of the roll is fixed on the support 17, the sealing cover 20 is closed. At this time, the bottom limiting component contacts the top of the roll. As the sealing container moves downward, multiple movable clamps 24 slide along the outer wall of the roll, thus being pushed by the outer wall, causing the moving rod 22 to move in the middle of the limiting ring 21. This compresses the spring 23, generating a rebound force that pushes the movable clamps 24 tightly into contact with the outer wall of the roll. This ensures the stability of the roll when it rotates inside the device. The surface of the movable clamp 24 that contacts the roll is equipped with ball bearings, ensuring that the roll can rotate without resistance under the drive of the bottom rotating component, while also maintaining rotational stability under the action of the upper limiting component.

[0065] Please see the appendix Figure 7The recycling component includes a water collection section 26, the upper surface of which is fixedly connected to the middle of the arc-shaped chassis 25. A connecting pipe 27 is provided through the middle of the water collection section 26. A screw pump 28 is fixedly connected to the output end of the connecting pipe 27. A conduit 29 is fixedly connected to the output end of the screw pump 28. A water purifier 32 is fixedly connected to the other end of the conduit 29. A delivery pipe 33 is fixedly connected to the output end of the water purifier 32. A sewage pipe 38 is fixedly connected to the other output end of the water purifier 32.

[0066] Specifically, as the continuous spray quenching process proceeds, the wastewater containing impurities flows into the water collection section 26. Under the action of the screw pump 28, it enters the water purifier 32 through the conduit 29. After purification by the water purifier 32, it flows into the liquid distribution pipe 34 through the delivery pipe 33 for use. Meanwhile, dirt and other impurities are discharged through the drain pipe 38. This solves the problems of coolant waste and environmental pollution, thereby achieving the goals of resource reuse, reducing production costs, and improving quenching effect.

[0067] Please see the appendix Figure 6 -Appendix Figure 7 The other end of the delivery pipe 33 is fixedly connected to a liquid separator 34. Both ends of the liquid separator 34 are fixedly connected to annular pipes 35. Multiple connecting pipes 36 are fixedly connected to the outer walls of the two annular pipes 35. The other ends of the multiple sets of connecting pipes 36 are fixedly connected to a sprayer 37.

[0068] Specifically, the treated wastewater enters the interior of the separator 34 and mixes with the coolant before use. During this process, the system configured in this invention operates synchronously to ensure that the temperature of the coolant is not affected. When the coolant and the recovered liquid are used, they flow into the two annular pipes 35 through the separator 34, and then through multiple connecting pipes 36 into multiple sprayers 37 and sprayed onto the rolls.

[0069] A maintenance box 30 is fixedly connected to the outer wall of the cylinder 1. The maintenance box 30 has a maintenance door 31 on its outer wall. The exterior of the water purifier 32 is located inside the maintenance box 30.

[0070] A base 40 is fixedly connected to the bottom of the cylinder 1, and a connector 39 is fixedly connected to the outer wall of the separator 34.

[0071] Specifically, connector 39 is used to connect to an external coolant storage device, thereby providing a continuous supply of coolant to the device.

[0072] The rotating component and the limiting component are located on the same vertical line.

[0073] Please see the appendix Figure 11 The spray quenching coolant recycling and control system includes:

[0074] A temperature sensor, which is installed inside the distributor 34, is used to detect the temperature of the coolant and the recovery liquid in the pipe;

[0075] PLC is used for overall control and coordination of system operation;

[0076] HMI is used by operators to monitor and adjust system parameters;

[0077] A temperature controller, located inside the separator 34, is used to regulate the temperature of the recovered liquid and coolant after they are mixed.

[0078] Specifically, when the treated recycled liquid is put into use, the device of this invention is driven by a spray quenching coolant recycling control system. The treated wastewater enters the distributor pipe 34 through the delivery pipe 33 and combines with the coolant at the mixing point. The internal temperature sensor monitors the temperature of the mixture in real time. Based on the feedback data from the temperature sensor, the PLC automatically adjusts the liquid delivery rate through the temperature controller to ensure that the temperature of the mixture is within the set range. If the temperature of the mixture is too high, the PLC will reduce the wastewater flow or increase the coolant flow to lower the temperature. If the temperature of the mixture is too low, the PLC will increase the wastewater flow or decrease the coolant flow to raise the temperature. The operator monitors the operating status of the system through the HMI interface and adjusts the set parameters, such as the upper and lower limits of temperature and the flow ratio. The system operates automatically, ensuring that the temperature of the mixture is maintained within the set range to meet the requirements of spray quenching. The coolant at such a suitable temperature flows into two annular pipes 35, and through multiple sets of connecting pipes 36 into the corresponding sprayer 37, which sprays the rolls for quenching. This solves the problems of coolant waste, environmental pollution, and unstable coolant temperature, thereby achieving the goals of resource reuse, reducing production costs, and improving quenching effect.
