Description

Technical Field

[0001] This utility model belongs to the technical field of ring rolling mills, specifically relating to a horizontal ring rolling mill oxide scale wastewater separation and collection device. Background Technology

[0002] Currently, to improve the surface quality of forgings, enhance machining conditions, and prevent surface defects from worsening, it is essential to perform surface cleaning on billets and forgings continuously during the forging process. In many cases, this cleaning involves removing the oxide scale that forms on the surface of the billet after heating. This oxide scale causes cracks, folds, scratches, inclusions, and unevenness on the surface of the billet or forging. Failure to remove this defect promptly will negatively impact subsequent forging processes.

[0003] The process of removing metal oxide scale from a ring rolling mill by flushing is a key technology in metal processing. The core of this process lies in utilizing the synergistic effect of high-pressure water jets and specific chemical agents to remove oxide scale from the surface of hot-rolled steel billets. This method offers advantages such as saving labor, increasing efficiency, reducing die wear, reducing raw material consumption, and reducing subsequent machining workload. However, the wastewater containing chemical agents and the oxide scale itself need to be collected and recycled separately. Current collection devices simply involve installing a filter screen under the ring rolling mill. The oxide scale on the filter screen is flushed into the oxide scale collection box by the wastewater. The problem is that the oxide scale falling onto the filter screen is not completely collected, leaving residues, and the collection efficiency is low, requiring secondary manual cleaning. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a horizontal ring rolling mill oxide scale wastewater separation and collection device. It uses a power device to drive an electromagnetic chuck to move back and forth on the filter screen to collect the oxide scale that falls on the filter screen into the oxide scale collection box. This is convenient, fast, and effective in collecting wastewater and oxide scale separately, thereby improving production efficiency.

[0005] The technical solution adopted by this utility model is: a horizontal ring rolling mill oxide scale wastewater separation and collection device, including a filter screen, a wastewater collection tank, an oxide scale collection device, and an oxide scale collection box. The filter screen is equipped with a collection device for collecting oxide scale, and a wastewater collection tank for holding wastewater is located directly below the filter screen. An oxide scale collection box for holding oxide scale is located at the front end of the filter screen. The oxide scale collection device includes an electromagnetic chuck, a movable support for supporting the electromagnetic chuck's back-and-forth movement on the filter screen, a power device for driving the electromagnetic chuck to move back and forth along the length of the filter screen to collect oxide scale, and a fixed support for supporting the power device. The power device is fixedly connected to the fixed support. The power device includes... The system comprises a base plate, guide rails, sliders, a fixing plate, a motor, gears, and a rack. The base plate is fixedly connected to the fixing bracket. Guide rails are arranged side by side on the left and right sides of the base plate. Two sets of sliders are slidably connected to the guide rails. A fixing plate is fixedly connected to the sliders through threaded holes. A motor is mounted on the fixing plate, and a gear is connected to the output end of the motor. A rack parallel to the guide rail is arranged in the middle of the guide rail. The gear and rack mesh and drive each other. The motor drives the gear to rotate, and the gear moves linearly along the rack, thereby driving the slider to run along the guide rail. This causes the electromagnetic chuck to move back and forth along the length of the filter screen. The electromagnetic chuck picks up the oxide scale and moves it above the oxide scale collection box. The coil inside the electromagnetic chuck is disconnected, the electromagnetic chuck loses power and loses its suction force, and the oxide scale falls into the oxide scale collection box.

[0006] Specifically, the electromagnetic chuck is fixed to the movable bracket at both ends by shafts. Rollers are provided on the lower left and right sides of the movable bracket. A connecting plate is provided on the movable bracket, and a connecting arm is provided on the connecting plate. The connecting arm is connected to the fixed plate on the slider.

[0007] Specifically, the guide rail is longer than the filter screen.

[0008] Specifically, the wastewater collection tank has a trapezoidal cross-sectional shape, and the front of the wastewater collection tank is lower than the rear to facilitate wastewater collection.

[0009] Specifically, baffles are provided on both sides of the filter screen to collect wastewater into a wastewater collection tank below the filter screen.

[0010] Specifically, the support is a three-dimensional frame structure composed of horizontal and vertical bars, with reinforcing ribs connecting the horizontal and vertical bars in the middle, and the height of the support is consistent with the front and rear height of the filter screen.

[0011] Specifically, the top of the oxide scale collection box is provided with a row of air holes, and an air pipe is provided in the air holes. The air pipe is connected to an air pressure source and is used to blow the oxide scale away from the box.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention has a simple structure and is easy to operate. It separates wastewater and oxide scale collection through a wastewater collection tank and an oxide scale collection tank, which is highly efficient and facilitates the recycling and reuse of wastewater.

[0014] This invention uses a power device to drive an electromagnetic chuck to move back and forth on a filter screen, collecting the oxide scale that falls on the filter screen and placing it above the oxide scale collection box. After disconnecting the coil on the electromagnetic chuck, the electromagnetic chuck is de-energized, releasing the oxide scale into the oxide scale collection box. Even if there is residual oxide scale, it can be blown into the collection box using an air gun. This method has high collection efficiency and improves production efficiency.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1As shown, this utility model is a horizontal ring rolling mill oxide scale wastewater separation and collection device, including a filter screen 1, a wastewater collection tank 2, an oxide scale collection device 3, and an oxide scale collection tank 4. The filter screen 1 is equipped with the collection device 3 for collecting oxide scale. The wastewater collection tank 2, which holds wastewater, is located directly below the filter screen 1. The oxide scale collection tank 4, which holds oxide scale, is located at the front end of the filter screen 1. The oxide scale collection device 3 includes an electromagnetic chuck 5, a movable support 6 on the outside of the electromagnetic chuck 5 for supporting the electromagnetic chuck 5 and allowing it to move back and forth on the filter screen 1, a power device 7 for driving the electromagnetic chuck 5 to move back and forth along the length of the filter screen 1 to collect oxide scale, and a fixed support 8 for supporting the power device 7. The power device 7 is fixedly connected to the fixed support 8. The power device 7 includes a base plate 9, a guide rail 10, a slider 11, and a fixing plate. 12. Motor 13, gear, rack 14. The fixed bracket 8 is fixedly connected to the base plate 9. The base plate 9 has guide rails 10 arranged side by side on the left and right sides. Two sets of sliders 11 are slidably connected to the guide rails 10. The sliders 11 are fixedly connected to the fixed plate 12 through threaded holes. The fixed plate 12 is equipped with a motor 13. The output end of the motor 13 is connected to a gear. The middle of the guide rail 10 is equipped with a rack 14 parallel to it. The gear and the rack 14 mesh and drive each other. The motor 13 drives the gear to rotate. The gear moves linearly along the rack 14, thereby driving the slider 11 to run along the guide rail 10. This drives the electromagnetic chuck 5 to move back and forth along the length of the filter screen 1. The electromagnetic chuck 5 picks up the oxide scale and runs above the oxide scale collection box 4. The coil inside the electromagnetic chuck 5 is disconnected. The electromagnetic chuck 5 loses power and loses its suction force. The oxide scale falls into the oxide scale collection box 4.

[0019] Preferably, the electromagnetic chuck 5 is fixed to the movable bracket 6 at both ends by shafts. Rollers 61 are provided on the lower left and right sides of the movable bracket 6. A connecting plate 62 is provided on the movable bracket 6. A connecting arm 63 is provided on the connecting plate 62. The connecting arm 63 is connected to the fixing plate 12 on the slider 11.

[0020] Preferably, the length of the guide rail 10 is longer than the length of the filter screen 1.

[0021] Preferably, the wastewater collection tank 2 has a trapezoidal cross-sectional shape, and the tank body 2 is configured such that the front height is lower than the rear height to facilitate wastewater collection.

[0022] Preferably, baffles 201 are provided on both sides of the filter screen 1 to collect wastewater into the wastewater collection tank 2 below the filter screen 1.

[0023] Preferably, the support 8 is a three-dimensional frame structure composed of horizontal bars and vertical bars, with reinforcing ribs connecting the horizontal bars and vertical bars in the middle, and the height of the support 8 is consistent with the front and rear height of the filter screen 1.

[0024] Preferably, the oxide scale collection box 4 is provided with a row of air holes 15 at the upper end, and an air pipe is provided in the air hole 15. The air pipe is connected to an air pressure source for blowing off the oxide scale near the box.

[0025] During operation, this utility model is positioned directly below the horizontal ring rolling mill. As the mill works, high-pressure water jets remove oxide scale from the forging surface. The removed scale falls onto the filter screen 1. After being washed by the high-pressure water, some of the scale falls into the scale collection box 3 at the front of the filter screen 1, while some remains on the screen. The motor 13 is then started, driving the gears to rotate. The gears move linearly along the rack 14, which in turn drives the slider 11 to run along the guide rail 10. This causes the electromagnetic chuck 5, located in the movable bracket 6 connected to the fixed plate 12 on the slider 11, to move back and forth on the filter screen 1. When the electromagnetic chuck 5 is working, its coil is energized, and it picks up the scale, moving it above the scale collection box 3. Then, the coil in the electromagnetic chuck 5 is disconnected, and the scale loses its suction power, causing it to fall randomly into the scale collection box 3. Even if there is remaining scale, an air gun blows it into the scale collection box 3, resulting in high collection efficiency and improved production efficiency.
