When the strip steel is pushed into the heating box 2 on the support seat 1, the friction will cause the strip steel to drive the upper rolling column 3 and the lower rolling column 4 to roll. When the upper rolling column 3 rolls, the upper rolling column 3 will drive the first rotating column 51 to rotate through the pulley.
[0019] The top of the inner wall of the heating box 2 is fixedly connected to the top of the positioning shaft 54, and the outer wall of the upper rolling column 3 is rotatably connected to the outer wall of the first rotating column 51 through a pulley, and the outer wall of the first rotating column 51 is rotatably connected to the inner wall of the heating box 2. When the strip steel is pushed into the heating box 2 on the support seat 1, the friction will cause the strip steel to drive the upper rolling column 3 and the lower rolling column 4 to roll. When the upper rolling column 3 rolls, the upper rolling column 3 will drive the first rotating column 51 to rotate through the pulley.
[0020] The vibration device 6 includes a second rotating column 61, the outer wall of the second rotating column 61 is fixedly connected with a fixing ring 62, the outer wall of the fixing ring 62 is fixedly connected with a lifting block 63, the outer wall of the lower rolling column 4 is rotatably connected to the outer wall of the second rotating column 61 through a pulley, the outer wall of the second rotating column 61 is rotatably connected to the inner wall of the heating box 2, and the lower rolling column 4 drives the pulley to transmit, thereby causing the second rotating column 61 to rotate, and the rotation of the second rotating column 61 will drive the fixing ring 62 to rotate. Since the fixing ring 62 is fixed with a lifting block 63 to form a cam, the fixing rings 62 at different positions will lift the strip steel at one time through the lifting block 63, thereby causing the strip steel to vibrate and shake off impurities at the bottom and top of the strip steel.
[0021] The collecting device 7 includes a fixing plate 71, an L-shaped guide groove 76 is arranged above the fixing plate 71, a collecting cover 72 is fixedly connected to the bottom of the fixing plate 71, a guide column 73 is rotatably connected to the inner wall of the collecting cover 72, a water inlet pipe 75 is fixedly connected to the inner wall of the collecting cover 72, a nozzle 74 is fixedly connected to the outer wall of the water inlet pipe 75, a servo motor 77 is fixedly connected to the top of the L-shaped guide groove 76, a fan 78 is fixedly connected to the output end of the servo motor 77, the outer wall of the L-shaped guide groove 76 is fixedly connected to the heating box 2 through a connecting plate 79, and the outer wall of the connecting plate 79 is fixedly connected to the outer wall of the L-shaped guide groove 76, a water outlet pipe 710 is fixedly connected to the bottom of the L-shaped guide groove 76, the outer wall of the water outlet pipe 710 is fixedly connected to the inner wall of the collecting cover 72, and the top of the collecting cover 72 is fixedly connected to the L-shaped guide groove.

At this time, the servo motor 77 is started, and the servo motor 77 drives the fan 78 to rotate. In the L-shaped guide groove 76, the fan 78 blows the airflow toward the water outlet pipe 710. The water flow that has not become water vapor will carry impurities along the gap between the guide columns 73 into the bottom of the space surrounded by the collection cover 72 and the fixed plate 71, and flow out of the annealing device along the water outlet pipe 710, thereby achieving the purpose of collecting cooling water and preventing impurities from leaking out and polluting the environment.
[0022] Working principle:
[0023] When in use, a cleaning device 5 is provided to clean the steel strip before cooling. When the steel strip is pushed into the heating box 2 on the support seat 1, the friction will cause the steel strip to drive the upper rolling column 3 and the lower rolling column 4 to roll. When the upper rolling column 3 is rolling, the upper rolling column 3 will drive the first rotating column 51 to rotate through the pulley. As the first rotating column 51 rotates, the worm 52 fixed on the first rotating column 51 will rotate accordingly. The worm wheel 53 is fixed in the rotation position by the positioning shaft 54. Under the meshing action, the worm wheel 53 will rotate on the positioning shaft 54. At the same time, the worm wheel 53 drives the sweeping block 55 to rotate. The sweeping block 55 sweeps off the protruding impurities on the steel strip by rotating, thereby reducing the amount of impurities discharged to the outside through water vapor during the cooling process.
[0024] The vibration device 6 is provided to vibrate the steel strip entering the entrance section of the heating box 2, thereby shaking off the oxide layer impurities attached to the surface of the steel strip. When the lower rolling column 4 starts to rotate, the lower rolling column 4 will drive the pulley transmission, thereby rotating the second rotating column 61. During the rotation of the second rotating column 61, the fixed ring 62 will be driven to rotate. Since a lifting block 63 is fixed on the fixed ring 62 to form a cam, the lifting blocks 63 on the fixed rings 62 at different positions are not in the same horizontal line. Therefore, when the second rotating column 61 rotates, the fixed rings 62 at different positions will lift the steel strip at one time through the lifting blocks 63, thereby vibrating the steel strip and shaking off the impurities at the bottom and top of the steel strip.
[0025] A collecting device 7 is provided to collect cooling water. When water flows into the water inlet pipe 75, the nozzle 74 evenly sprinkles water on the steel strip on the guide column 73. Since the steel strip is heated before annealing, the steel strip has a high temperature. Part of the water will vaporize quickly when in contact with it, thereby generating water vapor. At the same time, when the water impacts the steel strip, part of the water will be aroused. The water vapor affected by the impact moves upward due to its own molecular motion, and carries some impurities with it. At this time, the water vapor moving upward reaches the position of the L-shaped guide groove 76. At this time, the servo motor 77 is started, and the servo motor 77 drives the fan 78 to rotate. In the L-shaped guide groove 76, the fan 7 8 blows the air flow toward the water outlet pipe 710, and the water outlet pipe 710 is connected to the L-shaped guide groove 76. At this time, the water vapor will be affected by the air flow and move along the L-shaped guide groove 76 and the connecting plate 79, and finally reach the inside of the water outlet pipe 710. The water flow that has not become water vapor will flow into the bottom of the space surrounded by the collecting cover 72 and the fixing plate 71 along the gap between the guide columns 73 with impurities, and flow out of the annealing device along the water outlet pipe 710. Therefore, the impurities on the strip are collected by the collecting device 7 and are also removed from the water outlet pipe 710, thereby achieving the purpose of collecting cooling water and preventing impurities from leaking out and polluting the environment.
[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
