[0020] 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.

[0021] Example 1: Please refer to Figure 1-2 This utility model provides an embodiment of a device for recovering oxide scale blown away by high-pressure water descaling during hot rolling. The device is located below the roller conveyor and includes a recovery box 1 to hold a mixture of oxide scale and wastewater, a supporting filter screen 5, and a cleaning device 4. The rectangular hollow structure provides a large-capacity collection space. A sedimentation tank 8 is connected to the bottom for solid-liquid separation. The device also includes a hook 2, an adjusting device 3, the cleaning device 4, and the sedimentation tank 8. A drain pipe is connected to the sedimentation tank 8, and a one-way valve is installed on the drain pipe to control its opening and closing.

[0022] A pair of hooks 2 are symmetrically arranged on the left and right sides of the recycling box 1, respectively located on the front and rear sides. The hooks 2 are used to connect to the supports below the roller conveyor, suspending and fixing the device to these supports. The symmetrical distribution ensures balanced force distribution. They work in conjunction with the adjustment device 3 to adapt to different support spacings and adjust the distance between the hook and the working surface. Each hook 2 is equipped with an adjustment device 3. The recycling box 1 is a rectangular hollow shell with a removable filter screen 5 to intercept oxide scale, allowing wastewater to seep into the sedimentation tank 8, separating the oxide scale from the wastewater. The removable design facilitates installation and maintenance. Made of stainless steel, it meets the requirements for high temperature and corrosion resistance during production, extending its service life. The filter screen 5 is equipped with a cleaning device 4 to automatically remove accumulated oxide scale. The bottom of the recycling box 1 is connected to the sedimentation tank 8.

[0023] The cleaning device 4 is connected to the recycling box 1 via a support frame and includes a drive motor 401, a first connecting rod 402, a second connecting rod 403, a push rod 404, and a cleaning plate 405. The output end of the drive motor 401 is connected to the first connecting rod 402. Driven by the drive motor 401, the first connecting rod 402 rotates around the center of the drive motor 401. Simultaneously, the second connecting rod 403 moves, and the push rod 404 is constrained by the collection box 1, converting the rotational motion into linear reciprocating motion. The other end of the first connecting rod 402 is hinged to one end of the second connecting rod 403. The second connecting rod 403 and the first connecting rod 402 are offset in height. The other end of the second connecting rod 403 is hinged to one end of the push rod 404. The other end of the push rod 404 passes through the collection box 1 and slides within the collection box 1. A cleaning plate 405 is fixedly connected to the top end. The bottom end of the cleaning plate 405 is tightly fitted to the top end of the filter screen 5. The cleaning plate 405 pushes the oxide scale against the surface of the filter screen 5, discharging the oxide scale through the discharge trough 7 into the collection box 6.

[0024] The end of the recycling box 1 furthest from the cleaning device 4 has a collection and discharge trough 7. The bottom of the discharge trough 7 is flush with the top of the filter screen 5, ensuring that the oxide scale can be discharged into the collection box 6 for collection during the pushing process of the cleaning plate 405. A detachable collection box 6 is connected to the discharge trough 7.

[0025] In use, the device is connected to the support column below the roller conveyor via hook 2. It then collects scale and wastewater. After entering the recovery box 1, the scale and wastewater are separated by the filter screen 5. The wastewater enters the sedimentation tank 8 for sedimentation and is discharged through the drain pipe. Simultaneously, the drive motor 401 can be started when there is no steel material being processed or after production has stopped. The drive motor 401 drives the first connecting rod 402 to rotate. The first connecting rod 402 drives one end of the second connecting rod 403 to rotate around the output end of the drive motor 401. Simultaneously, the other end of the second connecting rod 403 drives the push rod 404 to move. The rotational motion is converted into linear motion by the contact end between the recovery box 1 and the push rod 404. The push rod 404 drives the cleaning plate 405 to push the scale on the surface of the filter screen 5, which is then discharged through the discharge trough 7 into the collection box 6.

[0026] Example 2: Please refer to Figure 1 , 3 Based on Example 1, it also has the following structure:

[0027] The adjusting device 3 includes a housing 301 and a locking screw 302. A slidable hook rod is provided inside the housing 301. When the spacing between the supports below the roller conveyor is not uniform, the position of the hook rod is adjusted to adjust the position of the hook 2 and connect it to the support. The top of the hook rod is fixedly connected to the hook 2, and the hook 2 extends out of the housing 301. Several threaded holes are equally spaced on the housing 301 along the sliding direction of the hook rod. Limiting holes are provided on the hook rod at the corresponding positions of the threaded holes. The locking screw 302 is provided with external threads and screws into the housing 301. The bottom end passes through the limiting hole. The locking screw 302 and the limiting hole are mechanically interlocked to prevent lateral displacement. At the same time, the connection with the threaded hole further limits the displacement and ensures a tight connection, abutting against the inner wall of the housing 301. When connecting, the hook 2 is adjusted, which simultaneously drives the hook rod to slide. After the hook 2 is connected to the support, the locking screw 302 is screwed into the housing 301. At the same time, the bottom end of the locking screw 302 passes through the limiting hole on the hook rod, completing the locking and positioning installation.
