[0023] See also Figure 1-3 , the utility model provides a technical solution:
[0024] A steel billet heating pretreatment device for steel rolling production comprises a base 1, an input conveyor belt 2, an output conveyor belt 3, and a preheating cylinder 4. The top center of the base 1 is fixedly connected to the preheating cylinder 4. An input port 12 is provided on one side of the top of the surface of the preheating cylinder 4. The input conveyor belt 2 is provided on the outside of the input port 12. The bottom of the input conveyor belt 2 is connected to the base 1. An output port 17 is provided on the other side of the bottom of the surface of the preheating cylinder 4. The output conveyor belt 3 is provided on the outside of the output port 17. The bottom of the output conveyor belt 3 is connected to the base 1. The inner surface of the preheating cylinder 4 is provided with a first partition plate 18 and a second partition plate 25. The first partition plate 1 8 is located above the second partition plate 25, the first inner cavity 26 is between the top of the first partition plate 18 and the top of the inner surface of the preheating cylinder 4, the bottom of the first partition plate 18 and the top of the second partition plate 25 are the heater inner cavity 20, the bottom of the second partition plate 25 and the bottom of the inner surface of the preheating cylinder 4 are between the second inner cavity 27, the bottom center of the second inner cavity 27 is fixedly connected with a rotating motor 22, the top output end of the rotating motor 22 is provided with a rotating shaft 23, the top of the rotating shaft 23 is located at the first inner cavity 26 and above the bottom of the input port 12, and the rotating shaft 23 is located at the first inner cavity 26 and is provided with a plurality of stirring blades 24.
[0025] Furthermore, an exchange port 5 is provided at the top center of the preheating cylinder 4 , and the inner surface of the exchange port 5 is connected to the outer surface of the air outlet fan 6 .
[0026] Specifically, during the preheating process, the preheating cylinder 4 needs to be ventilated with the external environment, so an exchange port 5 is designed here to exchange gas with the external environment. An air blower 6 is also provided here to discharge the internal gas of the preheating cylinder 4 into the external environment through the air blower 6. The gas in the external environment will enter the preheating cylinder 4 through the gap between the first sealing plate 7 and the second sealing plate 13, thereby realizing gas exchange.
[0027] Furthermore, a first sealing plate 7 is provided on the outer surface of the input port 12, and a first electric guide rail 8 is laterally provided at the center of one side of the top of the preheating cylinder 4. The first electric guide rail 8 is slidably connected with a first electric slider 9, and the outer side of the first electric slider 9 is connected to the top of the first sealing plate 7 through a first traction rope 10.
[0028] Furthermore, a second sealing plate 13 is provided on the outer surface of the output port 17, and a second electric guide rail 15 is horizontally arranged at the center of the other side of the top of the preheating cylinder 4. The second electric guide rail 15 is slidably connected with a second electric slider 16, and the outer side of the second electric slider 16 is connected to the top of the second sealing plate 13 through a second traction rope 14.
[0029] Specifically, during use, the preheating cylinder 4 needs to pour the steel billet into the input port 12. At this time, the staff needs to lift the first sealing plate 7. Specifically, the staff starts the first electric guide rail 8 through the controller. The start of the first electric guide rail 8 will move the first electric slider 9. After the first electric slider 9 moves inward, the first traction rope 10 will be pulled upward. After the first traction rope 10 is pulled upward, the first sealing plate 7 will be pulled up, thereby leaking the input port 12. Then the staff starts the input conveyor belt 2 through the controller. After the input conveyor belt 2 is started, the steel billet is placed at the starting point of the input conveyor belt 2. The steel billet will be transported to the input port 12 through the input conveyor belt 2.
[0030] After preheating is completed, the steel billet needs to enter the output conveyor belt 3 from the output port 17. Specifically, the staff starts the second electric guide rail 15 through the controller. The start of the second electric guide rail 15 will move the second electric slider 16. The inward movement of the second electric slider 16 will pull up the second traction rope 14. After the second traction rope 14 is pulled up, the second sealing plate 13 will be lifted. It should be noted that the first partition plate 18 and the extension plate 11 at the bottom of the output port 17 are both inclined, wherein the first partition plate 18 and the extension plate 11 at the bottom of the output port 17 are higher on the input port 12 side than the output port 17 side. After the second sealing plate 13 is opened, the steel billet will enter the output conveyor belt 3 and be transported to a suitable place.
[0031] Furthermore, extension plates 11 extend from the bottom of the input port 12 and the output port 17 , and the other ends of the two extension plates 11 are respectively located at the end point of the input conveyor belt 2 and the starting point of the output conveyor belt 3 .
[0032] Furthermore, the top of the first partition plate 18 and the bottom of the output port 17 are in the same horizontal plane, and a plurality of flame heaters 19 are disposed on the surface of the first partition plate 18 .
[0033] Furthermore, a protective cover 21 is provided on the surface of the rotating shaft 23 located in the inner cavity 20 of the heater. The top and bottom of the protective cover 21 are respectively connected to the bottom of the first partition plate 18 and the top of the second partition plate 25. The protective cover 21 protects the rotating shaft 23 located in the inner cavity 20 of the heater inside the protective cover 21, thereby protecting the rotating shaft 23.
[0034] Specifically, several electronic components used for the operation of the flame heater 19 are placed in the heater cavity 20 and outside the protective cover 21. It should be noted that this is an existing mature technology, and the specific connection method and working principle of the electronic components will not be described in detail here.
[0035] Working principle: Before use, the staff starts the first electric guide rail 8 to lift the first sealing plate 7, and the second sealing plate 13 is located at the output port 7, and then starts the input conveyor belt 2. After the input conveyor belt 2 is started, the steel billet is placed on the input conveyor belt 2. During transportation, the steel billet will enter the preheating cylinder 4. It should be noted that the top horizontal plane height of the steel billet inside the preheating cylinder 4 is not higher than the bottom horizontal plane of the input port 12. Then, after the steel billet is placed, start the first electric guide rail 8 again to move the first sealing plate 7 to the input port 12 to cover the input port 12.
[0036] Then start the rotating motor 22. The rotation of the rotating motor 22 will rotate the rotating shaft 23. The rotation of the rotating shaft 23 will rotate the stirring blades 24. Then start the flame heater 19 through the controller to heat the steel billet. During the heating process, the stirring blades 24 will move the steel billet to a certain extent, so that the steel billet can be preheated evenly. A small amount of dye can be used to better preheat the steel billet.
[0037] After preheating is completed, the staff starts the second electric guide rail 15, which will lift the second sealing plate 13, thereby pouring the steel billet onto the output conveyor belt 3, and the steel billet is transported to a suitable position through the output conveyor belt 3.
[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
