Description

Technical Field

[0001] This utility model relates to the field of baking equipment for smelting bread, and in particular to a heating device for baking bread in ferrous metal smelting. Background Technology

[0002] Ladle heating is a key step in the ferrous metal smelting process. The performance of the heating equipment significantly impacts converter tapping temperature, steelmaking operating rate, and furnace life. Ladle heating lies between steelmaking and casting, and its temperature plays a crucial role in coordinating the entire smelting process, with even greater significance for continuous casting. Molten steel is allowed to settle in the ladle for 5-10 minutes after tapping before pouring. During this settling process, the steel temperature decreases. The main heat losses are threefold: heat loss from the upper surface of the molten steel, overall heat loss from the ladle's outer surface, and heat loss from the ladle lining. The heat loss from the ladle lining accounts for approximately 40%-50% of the total heat loss. Therefore, reducing heat loss from the ladle can significantly minimize the temperature drop of the molten steel within it. This is crucial for lowering tapping temperature, extending converter life, increasing steel production, reducing raw material consumption, lowering the cost per ton of steel, and ensuring the smooth operation of continuous casting.

[0003] Ferrous metals refer to iron and its alloys (primarily steel and cast iron). These metals contain a high proportion of iron and are typically produced by smelting iron ore. Ferrous metals have a wide range of industrial applications, particularly in construction, machinery manufacturing, transportation, and energy.

[0004] Existing ladle baking machines for smelting mostly rely on steel frames for fixed installation, making it difficult to adjust the burner height. Different smelting processes, furnace charge types, and furnace designs may require different burner heights, and the inability to adjust the height prevents the burner from flexibly meeting varying production needs, thus impacting production efficiency. Furthermore, existing burners lack effective covering protection when not in use, potentially posing a safety hazard. Unprotected burners may retain high temperatures or incompletely extinguished flames even when not in use, leading to burns or fires for personnel near the equipment.

[0005] Therefore, considering the adaptability of the baking oven and the protection of the burner, a heating device for a baking oven in ferrous metal smelting is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a heating device for a baking oven for ferrous metal smelting, which achieves shielding and protection of the burner by setting a shielding and protection component and sets a cylinder to achieve free height adjustment of the burner.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A heating device for baking bread in ferrous metal smelting includes two parallel base plates; each of the two base plates is supported by a vertical beam, the two vertical beams are arranged vertically parallel, and each of the two vertical beams is clamped with two sliding plates.

[0009] The front ends of the four sliding plates are jointly supported by an installation beam. A steel ladle cover is horizontally installed on the outside of the installation beam. A hole is opened on the upper surface of the steel ladle cover and a burner is installed in the hole.

[0010] The lower end face of the steel ladle cover is provided with a shielding and protective component;

[0011] The shielding and protection assembly includes a mounting plate disposed on the lower end face of the steel ladle cover. Two linear guide rails are mounted on the lower end face of the mounting plate. Two guide rail sliders are fitted into the outside of each of the two linear guide rails. A connecting plate is mounted on the bottom of the four guide rail sliders. A shielding plate is mounted on the bottom of the connecting plate.

[0012] Two flame detection alarms are installed at the bottom of the shielding plate.

[0013] Furthermore, each of the two adjacent sliding plates is provided with two sets of rollers at its upper and lower ends, and the four sets of rollers are distributed in a rectangular shape and slide outside the vertical beam.

[0014] Furthermore, a lifting beam is provided at the rear end of each of the four sliding plates; a guide rod cylinder is vertically installed on the upper surface of the base plate, and the output end of the guide rod cylinder is vertically arranged and connected to the lifting beam.

[0015] Furthermore, the mounting plate has a U-shaped structure and both ends are vertically arranged; the shielding and protection assembly also includes a threaded screw rotatably mounted on the mounting plate, a screw nut is externally engaged with the threaded screw, and the bottom of the screw nut is connected to the connecting plate.

[0016] Furthermore, a forward and reverse motor is installed on one side of the mounting plate, and the output end of the forward and reverse motor passes through the mounting plate and extends to connect with one end of the lead screw nut.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. Through the coordinated movement of multiple structures within the shielding and protection assembly, the shielding plate within the assembly can move linearly, thereby achieving shielding and protection of the burner. Since the burner may remain at a high temperature even when not in operation, lack of shielding could lead to burns, fires, and other safety hazards. Driving the shielding plate through the shielding and protection assembly effectively blocks the flame emission point of the burner, preventing residual heat leakage and reducing the safety risks to operators. Simultaneously, when the burner is not in use, the shielding plate's coverage prevents accidental flame leakage, reducing the risk of accidents, especially during equipment commissioning or maintenance.

[0019] 2. Through pneumatic adjustment between the guide rod cylinder located on the upper surface of the base plate and the lifting beam, combined with the sliding plate sliding outside the vertical beam, the guide rod cylinder can drive the sliding plate to freely adjust its height. Simultaneously, the sliding plate can further adjust the height of the mounting beam, ladle cover, and burner. In practical use, adjusting the burner height ensures optimal distance between the burner and the ladle, achieving uniform heat distribution and preventing overheating or underheating. This ensures uniform heating of the ferrous metals inside the ladle, improving heating efficiency. Furthermore, the cylinder-adjusted burner heating height can be adjusted according to different ladle sizes and heating requirements, allowing the burner to flexibly meet various production needs without requiring cumbersome manual adjustments.

[0020] 3. Two flame monitoring alarms installed at the bottom of the shielding plate can monitor the flame emission of the burner. When the burner is not in operation, the flame monitoring alarms can detect in real time whether the flame is still present. If the burner emits flames while in the shielded state, the flame monitoring alarms will generate an alarm, thereby reminding the staff to turn off the burner in time, thus preventing outsiders from being injured when passing by the burner.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] First embodiment;

[0028] Reference Figure 1-3 As shown, a heating device for baking bread in ferrous metal smelting is provided in a preferred embodiment of the present invention, comprising two parallel base plates 1; vertical beams 2 are supported on both base plates 1, the two vertical beams 2 are arranged in parallel vertically, and two sliding plates 3 are sandwiched on the outside of each of the two vertical beams 2.

[0029] The front ends of the four sliding plates 3 are jointly supported by the mounting beam 5. A steel ladle cover 6 is horizontally installed on the outside of the mounting beam 5. The upper surface of the steel ladle cover 6 has a hole and a burner 7 is installed in the hole.

[0030] The lower end face of the ladle cover 6 is provided with a shielding and protective component 8;

[0031] The shielding and protection component 8 includes a mounting plate 81 disposed on the lower end face of the steel ladle cover 6. Two linear guide rails 82 are mounted on the lower end face of the mounting plate 81. Two guide rail sliders 83 are fitted on the outside of each of the two linear guide rails 82. A connecting plate 831 is mounted on the bottom of the four guide rail sliders 83. A shielding plate 84 is mounted on the bottom of the connecting plate 831.

[0032] Two flame detection alarms 88 are installed at the bottom of the shielding plate 84.

[0033] In this embodiment, the mutual movement and cooperation of multiple structures disposed within the shielding and protection assembly 8 allows the shielding plate 84 disposed within the shielding and protection assembly 8 to move linearly, thereby achieving shielding and protection for the burner 7. Since the burner 7 is prone to remaining at a high temperature when not in operation, lack of shielding may lead to safety hazards such as burns and fires. By driving the shielding plate 84 through the shielding and protection assembly 8, the flame emission position of the burner 7 can be effectively blocked, preventing residual heat leakage and reducing the safety risks to operators. At the same time, when the burner 7 is not in use, the covering and shielding of the shielding plate 84 can prevent accidental flame leakage caused by unintentional operation, reducing the risk of accidents, especially when the equipment is being debugged or maintained.

[0034] Furthermore, two flame monitoring alarms 88 installed at the bottom of the shielding plate 84 can monitor the flame emission of the burner 7. When the burner 7 is not in operation, the flame monitoring alarms 88 can detect in real time whether the flame is still present. If the burner 7 emits flames while in the shielded state, the flame monitoring alarms 88 will generate an alarm, thereby reminding the staff to turn off the burner 7 in time, thus preventing outside personnel from being injured when passing by the burner 7.

[0035] It should be noted that, as in the embodiments Figure 1 As shown, the ladle cover 6 includes an integrally formed disc portion and a rectangular portion. The mounting beam 5 is connected to the rectangular portion of the ladle cover 6. The burner 7 is assembled at the center of the disc portion of the ladle cover 6. The shielding and protective assembly 8 is assembled on the lower end face of the rectangular portion of the ladle cover 6.

[0036] By designing the rectangular portion of the ladle cover 6, the shielding and protective assembly 8 can be positioned away from the flame exit point of the burner 7 during installation, ensuring that the residual heat of the burner 7 does not affect the normal installation of the shielding and protective assembly 8 during operation; simultaneously, in the preferred embodiment, as in the example... Figure 3 As shown, when the shielding plate 84 is at its maximum shielding stroke, it can completely shield the nozzle of the burner 7.

[0037] Second embodiment;

[0038] Reference Figure 1-2 As shown, two sets of rollers 4 are provided at the upper and lower ends of two adjacent sliding plates 3. The four sets of rollers 4 are distributed in a rectangular shape and slide outside the vertical beam 2.

[0039] Third embodiment;

[0040] Reference Figure 1-2As shown, the rear ends of the four sliding plates 3 are jointly supported by a lifting beam 91; a guide rod cylinder 9 is vertically installed on the upper surface of the base plate 1, and the output end of the guide rod cylinder 9 is vertically arranged and connected to the lifting beam 91. Through the pneumatic adjustment between the guide rod cylinder 9 and the lifting beam 91 on the upper surface of the base plate 1, and in conjunction with the sliding of the sliding plates 3 outside the vertical beam 2, the guide rod cylinder 9 can drive the sliding plates 3 to freely adjust their height; at the same time, the sliding plates 3 can further drive the mounting beam 5, the ladle cover 6, and the burner 7 to adjust their height.

[0041] In practical use, the height adjustment of the burner 7 via the guide rod cylinder 9 ensures optimal distance between the burner 7 and the ladle, thereby achieving uniform heat distribution and avoiding overheating or underheating. This ensures uniform heating of the ferrous metals inside the ladle, improving heating efficiency. Furthermore, the cylinder-adjusted heating height of the burner 7 can be adjusted according to different ladle sizes and heating requirements, allowing the burner 7 to flexibly meet various production needs without requiring cumbersome manual adjustments.

[0042] Fourth embodiment;

[0043] Reference Figure 3 As shown, the mounting plate 81 has a U-shaped structure with both ends vertically positioned. The shielding and protective assembly 8 also includes a threaded screw 85 rotatably mounted on the mounting plate 81, with a screw nut 86 meshing with the outside of the threaded screw 85. The bottom of the screw nut 86 is connected to the connecting plate 831. In use, the threaded screw 85 is rotatably mounted at both ends of the mounting plate 81. When the threaded screw 85 rotates, it is limited by the connection of the linear guide rail 82 and the guide rail slider 83, allowing the screw nut 86, which is threaded onto the outside of the threaded screw 85, to reciprocate linearly along the stroke range of the threaded screw 85. At this time, the movement of the screw nut 86 drives the connecting plate 831 to move linearly along the linear guide rail 82. Finally, through the connection between the connecting plate 831 and the shielding plate 84, the shielding plate 84 is driven to move linearly.

[0044] Furthermore, by controlling the extension stroke of the shielding plate 84, the user can shield and protect the burner 7. At the same time, when the burner 7 is working, the user can drive the shielding and protection component 8 to retract the shielding plate 84.

[0045] Fifth embodiment;

[0046] Reference Figure 3As shown, a reversible motor 87 is mounted on one side of the mounting plate 81. The output end of the reversible motor 87 passes through the mounting plate 81 and extends to connect to one end of the lead screw nut 86. The reversible motor 87 can be used to control the rotation of the lead screw 85. The lead screw 85 is connected to a motor controller, which can control the number of rotations and the direction of rotation of the motor. In use, the power supply connection of the motor is existing technology, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0047] Specific implementation process:

[0048] Step 1: In actual use, when the user needs to adjust the heating height of the burner 7, the guide rod cylinder 9 is connected to an external air source and an output air pressure value is given to the guide rod cylinder 9. At this time, the guide rod cylinder 9 will drive the lifting beam 91 to move up and down. When the lifting beam 91 moves, the sliding plate 3 connected to the lifting beam 91 will follow and move up and down outside the vertical beam 2. Due to the sliding cooperation between the roller 4 and the vertical beam 2, the sliding plate 3 moves up and down more smoothly.

[0049] Step 2: The user controls the stroke of the output end of the guide rod cylinder 9 according to the needs. Through the installation of the sliding plate 3, the mounting beam 5, and the ladle cover 6, the height of the ladle cover 6 and the burner 7 can be precisely controlled.

[0050] Step 3: After the burner 7 height is adjusted, the user places the ladle under the ladle cover 6 and then adjusts the shielding and protective component 8. This allows the shielding plate 84 to be adjusted linearly, thus removing the shield from the burner 7. Once the shielding plate 84 is fully retracted, the burner 7 can be started to heat the ladle. After the burner 7 has finished heating, the user can drive the shielding and protective component 8 again, causing the shielding plate 84 to move linearly again until it is below the burner 7 and shields the nozzle. At this time, the flame monitoring alarm 88 located at the bottom of the shielding plate 84 can be used to monitor the flame. During non-working hours, if the burner 7 emits a flame, the user will be alerted by the flame monitoring alarm 88 and can shut down the burner 7 in time.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
