Abstract
Description
Technical Field
[0001] This application relates to the field of rolling mill technology, and in particular to an environmentally friendly oil-water separation two-roll rolling mill. Background Technology
[0002] Rolling is a pressure processing method in which metal billets are passed through the gap between a pair of rotating rolls (of various shapes), and the cross-section of the material is reduced and the length is increased due to the compression of the rolls. It is currently the most common production method for steel, mainly used to produce profiles, plates and pipes.
[0003] During the rolling process, the workpiece reaches a high temperature, requiring water for cooling. Similarly, the bearings and gears of the rolling mill operate at high speeds and temperatures, necessitating lubrication and cooling with a lubricant or coolant. However, current continuous rolling mills use emulsions for cooling or lubrication of the workpiece, gears, and bearings. These emulsions introduce numerous impurities during the rolling process, primarily solid particles, grease impurities, and insoluble impurities formed from grease, emulsifiers, and calcium and magnesium ions in the water. Therefore, using emulsions to lubricate the bearings and gears of continuous rolling mills will lead to rapid damage, severely impacting normal production. Utility Model Content

[0034] This application discloses an environmentally friendly two-roll mill for oil-water separation.
[0035] Reference Figure 1 An environmentally friendly oil-water separation two-roll mill includes a base 1, two rolls 21 and a drive source. Two mounting plates 2 are fixedly installed on the base 1 and are vertically installed on the base 1. The two rolls 21 are rotatably installed between the two mounting plates 2. The two ends of the rolls 21 pass through the mounting plates 2 and bearings are installed in the mounting plates 2. There is a gap between the two rolls 21 for the workpiece to pass through.
[0036] A drive source is located at one end of the base 1 to drive the rollers 21 to rotate. A transmission assembly is provided between the drive source and the rollers 21. The drive source is a drive motor 11, and the output shaft of the drive motor 11 is connected to the input end of the transmission assembly. The two output ends of the transmission assembly are fixedly connected to the two rollers 21 respectively. A transmission box 12 is fixedly installed on the base 1, and the transmission assembly is located inside the transmission box 12. In this embodiment, the transmission assembly is a gear transmission, and the transmission box 12 is filled with lubricating oil or grease. When the drive motor 11 rotates, it can synchronously drive the two rollers 21 to rotate through the action of the transmission assembly, thereby realizing the rolling operation.
[0037] Reference Figure 1 and Figure 2 It also includes a cooling system for cooling the roll 21. The cooling system includes a spray pipe 31, which is mounted on the mounting plate 2 for spraying coolant onto the roll 21. The spray pipe 31 is located above the uppermost roll 21 and extends along the length of the roll 21. The spray pipe 31 has a plurality of spray holes distributed along the length of the spray pipe 31.
[0038] Optionally, nozzles 311 are connected to both ends of the spray pipe 31. The nozzles 311 are inclined toward the mounting plate 2. The coolant sprayed from the two nozzles 311 is directed toward the side wall of the mounting plate 2 near the roll 21, thereby cooling the mounting plate 2 and reducing the temperature of the bearing inside the mounting plate 2.
[0039] Optional, refer to Figure 2 and Figure 3 A water collection trough 41 is formed on the top wall of the base 1 along its width direction. The water collection trough 41 is closed at both ends along the width direction of the base 1, and the length direction of the base 1 is the axial direction of the roll 21. A water pump 15 is installed on the base 1, located on the side wall of the base 1. The input end of the water pump 15 is connected to the water collection trough 41, and the output end is connected to the spray pipe 31. A collection trough 4 is formed on the top wall of the base 1, connected to the water collection trough 41. The water collection trough 41 is located in the middle of the collection trough 4, and the bottom wall of the collection trough 4 is inclined downward from the end away from the water collection trough 41 to the end closer to the water collection trough 41. After the coolant sprayed from the spray pipe 31 cools the rolled workpiece, it is collected through the water collection trough 41 and enters the collection trough 4. The surface of the collection trough 4 is inclined to facilitate the rapid flow of coolant into the collection trough 4.
[0040] Optional, refer to Figure 3 and Figure 4 A filter box 5 is embedded in the water collection tank 41, and filter holes are formed in the bottom wall of the filter box 5. The height of the filter box 5 is less than the depth of the water collection tank 41. A discharge port is provided at one end of the filter box 5, and a collection box 6 is provided on the side wall of the base 1, which is connected to the discharge port. An ear plate 51 is fixedly provided on the top of the filter box 5. An embedding groove 42 adapted to the ear plate 51 is formed at the end of the collection tank 4 near the water collection tank 41. The thickness of the ear plate 51 is not greater than the depth of the embedding groove 42, so that the coolant can flow smoothly into the collection box 6. The embedding groove 42 cooperates with the ear plate 51 to position the collection box 6 and facilitate the installation or replacement of the collection box 6.
[0041] Optional, refer to Figure 3 and Figure 5 A cleaning plate 52 is slidably disposed inside the filter box 5, and the filter box 5 is provided with a drive assembly for driving the cleaning plate 52 to slide. The drive assembly includes a drive cylinder 13, which is fixedly disposed on the base 1. The piston rod of the drive cylinder 13 passes through the side plate of the filter box 5 and extends into the filter box 5. The piston rod of the drive cylinder 13 is fixedly connected to the cleaning plate 52, and the bottom of the cleaning plate 52 contacts the bottom wall of the filter box 5. The drive cylinder 13 drives the cleaning plate 52 to move along the length of the filter box 5, thereby pushing the impurities in the filter box 5 into the collection box 6, preventing excessive impurities in the filter box 5 from clogging the filter holes, and making impurity cleaning convenient; the collection box 6 is located on one side of the base 1 for easy operation.
[0042] Optional, refer to Figure 4 and Figure 5 The collection box 6 is slidably mounted on the side wall of the base 1 along its height direction. A dovetail groove 14 is vertically formed on the side wall of the base 1. The collection box 6 includes a back plate 61, which is positioned close to the side wall of the base 1. A dovetail block is fixedly mounted on the back plate 61 and slidably positioned within the dovetail groove 14. The collection box 6 is equipped with a limiting member for defining its position. In this embodiment, the limiting member is an abutment bolt 62, which is threaded through the back plate 61 and abuts against the bottom wall of the dovetail groove 14 to fix the position of the collection box 6. When it is necessary to clean the impurities inside the collection box 6, the abutment bolt 62 is loosened, and the collection box 6 is pushed upwards to remove it. The operation is simple and convenient.
[0043] To prevent coolant leakage from the end of the filter box 5 near the collection box 6, the collection box 6 is fitted against the side wall of the base 1, and a sealing strip made of rubber is provided between the back plate 61 and the base 1. After the impurities in the filter box 5 are cleaned, the filter box 5 is pushed upwards, causing the back plate 61 to seal the outlet of the filter box 5, preventing coolant from flowing out. When it is necessary to clean impurities, the collection box 6 is moved downwards, so that the collection box is located below the filter box 5, allowing impurities to enter the collection box 6 smoothly.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
