Description

Technical Field

[0038] In one embodiment, ventilation meshes 27 penetrate through the opposite ends of the two air storage cylinders 21, and the two ventilation meshes 27 ensure the lateral movement of the two pistons 22.

[0039] Working principle:

[0040] When the aluminum coil annealing furnace is actually used, the aluminum coil is placed on the rotating table 10, and then the control panel is used to operate the electric telescopic rod 3, the electric heating rod 5, the electric heater 6 and the suction air pump 31, and the two sets of electromagnetic valves 30 are opened and closed at the same time. When the electric heating rod 5 is inserted into the aluminum coil, the electric telescopic rod 3 is stopped, and the suction air pump 31 can fill the air into the two sets of air storage cylinders 21 through the air storage box 28 and the two sets of connecting pipes 29. This part of the air can push the two sets of pistons 22, and the two sets of pistons 22 drive the two sets of mounting plates 24 to move toward each other through the two sets of cross bars 23. When the four sets of contact wheels 11 contact the aluminum coil, the suction air pump 3 is stopped. 1, close the two sets of electromagnetic valves 30 at the same time, and then use the control panel to make the double-axis motor 9 work. The upper output end of the double-axis motor 9 can drive the aluminum coil to rotate through the rotating table 10. The four sets of friction wheels 11 are subjected to the friction of the aluminum coil and can rotate with the help of the four sets of mounting shafts 26, so that the four sets of friction wheels 11 do not affect the rotation of the aluminum coil. The electric heating rod 5 and the electric heater 6 can evenly heat the aluminum coil. When the aluminum coil is annealed, stop the electric heating rod 5 and the electric heater 6, and at the same time open and close the two sets of electromagnetic valves 30 and reset the electric telescopic rod 3, and then use the suction pump 31 to extract the air inside the two sets of air storage cylinders 21. The four groups of friction wheels 11 can be reset to wait for the next use. The friction wheels 11 are set to ensure the stability of the rotation of the aluminum coil, which improves the practicality of the aluminum coil annealing furnace. At the same time, according to the above operation, the upper output end of the double-axis motor 9 can drive the rotating table 10 to rotate by using the control panel, and the lower output end of the double-axis motor 9 can drive the two groups of air outlet pipes 13 to rotate through the shaft tube 12. The rotating two groups of air outlet pipes 13 can stir the purified liquid inside the liquid storage tank 7. The control panel is used to make the induced draft fan 16 work, and the induced draft fan 16 can exhaust the exhaust gas inside the box body 2 through the air guide pipe 15 and the exhaust pipe 17. The waste gas is drawn into the liquid storage tank 7 and contacts the purification liquid, which can purify it. Finally, the purified waste gas can be discharged through the multiple sets of air outlet holes 18. The impurities in the atmosphere are intercepted by the multiple sets of filter screens 19 and cannot enter the interior of the liquid storage tank 7. The rotating rotating tube 32 can drive the two sets of brush plates 33 to rotate. Since the multiple sets of air outlet holes 18 and the two sets of brush plates 33 are located on the same horizontal plane, the two rotating sets of brush plates 33 can scratch the surface of the multiple sets of filter screens 19. The set air outlet holes 18 and filter screens 19 can prevent impurities in the atmosphere from entering the interior of the liquid storage structure, thereby reducing the workload for cleaning the liquid storage structure of the aluminum coil annealing furnace.
