Description

Technical Field

[0001] This application relates to the field of segmented furnace door technology, specifically a rigid-sealed segmented furnace door. Background Technology

[0002] In modern industrial production, industrial furnaces, as important heat processing equipment, are widely used in many fields such as metallurgy, machinery manufacturing, chemical industry, and building materials. Whether it is the high-temperature heating in the steel smelting process or the strict control of temperature and atmosphere during ceramic firing, industrial furnaces play a crucial role. As an important component of industrial furnaces, the performance of the furnace door directly affects the furnace's working efficiency, energy consumption, and production safety.

[0003] Currently, industrial furnaces generally adopt an integral furnace door structure, with a width of 4 to 8 meters to meet the needs of large workpieces entering and exiting. The furnace door is an integral structure. Due to the wide furnace door (about 6 meters), a large opening is formed when the furnace door is opened and closed, resulting in rapid heat loss inside the furnace and a large heat loss inside the furnace.

[0004] Existing equipment also requires controlling the furnace door to open and close over a wide range when a small amount of material is entering or leaving. During the opening and closing process, this integral furnace door will form a large opening, causing the heat inside the furnace to dissipate rapidly and resulting in a large heat loss inside the furnace. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a rigid, sealed, segmented furnace door, which has advantages such as reduced energy loss and solves the problem of rapid heat loss from the furnace when there is a small amount of material.

[0006] To achieve the above objectives, this application provides the following technical solution: a rigid-sealed segmented furnace door, comprising a mounting frame, an insulation layer fixedly mounted on the inner wall of the mounting frame, a furnace door body slidably connected to the outer surface of the insulation layer, two track grooves formed on the inner wall of the insulation layer, two limiting blocks fixedly connected to the outer surface of the furnace door body, each limiting block having its outer surface slidably connected to a corresponding track groove, two door panels slidably connected to the inner wall of the mounting frame, each door panel having its outer surface slidably connected to the furnace door body and the insulation layer, and a pressure relief port fixedly mounted on the outer surface of the furnace door body.

[0007] Through the above scheme, the mounting bracket, as the basic frame of the entire furnace door, is welded from high-strength steel, possessing extremely high rigidity and stability. It can withstand the high temperature, high pressure, and mechanical stress caused by frequent opening and closing operations during the operation of the industrial furnace, providing reliable installation support for other components of the furnace door. The heat insulation layer uses high-performance ceramic fiber material, which has excellent heat insulation performance and can effectively prevent the high temperature inside the furnace from being transferred to the outside. This not only reduces the surface temperature of the furnace door and ensures the safety of operators, but also reduces heat loss and improves the energy utilization efficiency of the industrial furnace. The pressure relief port adopts an intelligent pressure sensing design. When the internal pressure of the industrial furnace exceeds the safety threshold, the pressure relief port will automatically open to quickly release the excessive pressure and avoid safety accidents such as explosions caused by excessive pressure, providing a reliable guarantee for the safe operation of the industrial furnace. The door panel is composed of a left furnace door and a right furnace door to form a segmented furnace door. When a small amount of material needs to be fed or discharged, only one door panel needs to be opened to reduce the opening of the furnace body, avoid a large amount of heat loss inside the furnace, and thus reduce heat loss inside the furnace.

[0008] Furthermore, two first motors are fixedly mounted on the upper surface of the mounting frame, and a first take-up reel is fixedly connected to the output end of each first motor.

[0009] With the above scheme, the first take-up reel rotates synchronously with the output shaft of the first motor.

[0010] Furthermore, a second connecting plate is fixedly connected to the upper surface of each door panel, and a chain is fixedly connected to the upper surface of each second connecting plate. The end of each chain away from the corresponding second connecting plate is fixedly connected to the corresponding first winding reel.

[0011] Through the above scheme, the second connecting plate plays a key role in the drive system of the furnace door. The second connecting plate is connected to the door panel by high-strength bolts. The bolts are made of high-temperature resistant stainless steel, and high-strength thread-locking agent is applied to the connection to ensure that the connecting plate and the door panel remain firmly connected under frequent vibration and temperature changes, and there will be no loosening or falling off. As a key component for transmitting power, the chain drives the door panel to open and close during the rotation of the first winding reel.

[0012] Furthermore, a number of connecting blocks are fixedly connected to the upper surface of the mounting frame, and a guide wheel is rotatably connected to the outer surface of each connecting block, and the outer surface of each guide wheel is connected to the corresponding chain drive.

[0013] With the above solution, each connecting block has high-precision bearing mounting holes on its outer surface. Deep groove ball bearings are installed by interference fit to achieve rotational connection with the guide wheel. The outer circumference of the guide wheel is designed with V-shaped grooves that match the chain links to ensure that the chain can be accurately embedded and effectively prevent the chain from slipping or derailing during operation. The direction of chain movement can be changed by setting the guide wheel.

[0014] Furthermore, two first connecting plates are fixedly connected to the upper surface of the furnace door body, and a sling is fixedly connected to the upper surface of each first connecting plate. Two second winding reels are rotatably connected to the outer surface of the mounting frame, and a second winding reel is fixedly connected to the end of each sling away from the corresponding first connecting plate.

[0015] With the above solution, the two first connecting plates, as key connecting components between the furnace door body and the lifting cable, play a crucial role in the installation, commissioning and daily operation of the furnace door. The movement of the lifting cable can cause the furnace door body to slide vertically along the mounting frame.

[0016] Furthermore, a second motor is fixedly mounted on the upper surface of the mounting bracket, and two transmission wheels are rotatably connected to the outer surface of the mounting bracket. The output end of the second motor is fixedly connected to one of the transmission wheels.

[0017] With the above solution, a second motor is fixedly installed on the upper surface of the mounting frame. This motor is one of the core power sources of the entire furnace door transmission system, providing an indispensable driving force for the stable operation of the furnace door. When the second motor is started, it will drive the transmission wheel fixedly connected to it to rotate on the mounting frame.

[0018] Furthermore, a gear is fixedly connected to the outer surface of each of the transmission wheels, and the outer surface of each gear meshes with another gear.

[0019] With the above scheme, when the second motor starts, its output torque causes the two gears to rotate synchronously in opposite directions through the meshing between them, and the power is transmitted to another drive wheel through the transmission belt. The two drive wheels work together so that the corresponding second winding reel can wind and unwind the sling, thereby allowing the furnace door body to be opened and closed.

[0020] Furthermore, two drive belts are provided above the mounting frame, and the outer surface of each drive belt is connected to the corresponding second take-up reel and drive wheel.

[0021] The above solution allows the suspension cables on both sides of the furnace door to operate synchronously via the transmission belt, resulting in uniform force distribution on the furnace door during opening and closing, and more stable opening and closing of the furnace door.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This rigid-sealed segmented furnace door replaces the traditional integral furnace door with a segmented furnace door formed by the combination of a left and right furnace door. The lifting and lowering of one side of the furnace door is controlled by an independent suspension mechanism. By controlling the start and stop of two first motors, the corresponding first winding reel can be used for winding and unwinding. This allows for the lifting and adjustment of the door panel on one side. The opening of the furnace body can be reduced by opening and closing the door panel on one side, which can prevent a large amount of heat loss from the furnace and thus reduce the heat loss inside the furnace.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a rigid-sealed segmented furnace door includes a mounting frame 1. A heat insulation layer 2 is fixedly installed on the inner wall of the mounting frame 1. A furnace door body 3 is slidably connected to the outer surface of the heat insulation layer 2. Two track grooves 15 are opened on the inner wall of the heat insulation layer 2. Two limiting blocks 16 are fixedly connected to the outer surface of the furnace door body 3. The outer surface of each limiting block 16 is slidably connected to the corresponding track groove 15. Two door panels 5 are slidably connected to the inner wall of the mounting frame 1. The outer surface of each door panel 5 is slidably connected to the furnace door body 3 and the heat insulation layer 2. A pressure relief port 4 is fixedly installed on the outer surface of the furnace door body 3.

[0033] Please see Figure 2 and Figure 3 Two first motors 8 are fixedly installed on the upper surface of the mounting frame 1. Each first motor 8 has a first take-up reel 10 fixedly connected to its output end. The first take-up reel 10 rotates synchronously with the output shaft of the first motor 8.

[0034] Please see Figure 1 and Figure 3 Each door panel 5 has a second connecting plate 12 fixedly connected to its upper surface, and each second connecting plate 12 has a chain 11 fixedly connected to its upper surface. The end of each chain 11 away from the corresponding second connecting plate 12 is fixedly connected to the corresponding first winding reel 10. The second connecting plate 12 plays a key role in the drive system of the furnace door. The second connecting plate 12 is connected to the door panel 5 by high-strength bolts. The bolts are made of high-temperature resistant stainless steel, and high-strength thread locking agent is applied to the connection to ensure that the connecting plate and the door panel 5 remain firmly connected under frequent vibration and temperature changes, and there will be no loosening or falling off. As a key component for transmitting power, the chain 11 drives the door panel 5 to open and close during the rotation of the first winding reel 10.

[0035] Please see Figure 3 and Figure 4 The upper surface of the mounting frame 1 is fixedly connected with several connecting blocks 13. Each connecting block 13 has a guide wheel 14 rotatably connected to its outer surface. The outer surface of each guide wheel 14 is connected to the corresponding chain 11. Each connecting block 13 has a high-precision bearing mounting hole on its outer surface. A deep groove ball bearing is installed by interference fit to achieve rotational connection with the guide wheel 14. The outer circumferential surface of the guide wheel 14 is designed with a V-shaped groove that matches the chain link of the chain 11 to ensure that the chain 11 can be accurately embedded and effectively prevent the chain 11 from slipping or derailing during operation. The direction of movement of the chain 11 can be changed by setting the guide wheel 14.

[0036] Please see Figure 1 , Figure 5Two first connecting plates 6 are fixedly connected to the upper surface of the furnace door body 3. Each first connecting plate 6 is fixedly connected to a sling 7 on its upper surface. Two second winding reels 20 are rotatably connected to the outer surface of the mounting frame 1. Each sling 7 is fixedly connected to a second winding reel 20 at the end away from the corresponding first connecting plate 6. These two first connecting plates 6 are key connecting components between the furnace door body 3 and the sling 7. They play a crucial role in the installation, debugging and daily operation of the furnace door. The movement of the sling 7 can drive the furnace door body 3 to slide vertically along the mounting frame 1.

[0037] Please see Figure 5 A second motor 9 is fixedly installed on the upper surface of the mounting frame 1. Two transmission wheels 18 are rotatably connected to the outer surface of the mounting frame 1. The output end of the second motor 9 is fixedly connected to one of the transmission wheels 18. The second motor 9 is fixedly installed on the upper surface of the mounting frame 1. This motor is one of the core power sources of the entire furnace door transmission system, providing an indispensable driving force for the stable operation of the furnace door. When the second motor 9 starts, it will drive the transmission wheel 18 fixedly connected to it to rotate on the mounting frame 1.

[0038] Please see Figure 3 , Figure 4 and Figure 5 Each drive wheel 18 has a gear 17 fixedly connected to its outer surface. The outer surface of each gear 17 meshes with another gear 17. When the second motor 9 starts, its output torque causes the two gears 17 to rotate synchronously in opposite directions through the meshing between them. The power is then transmitted to the other drive wheel 18 through the drive belt 19. The two drive wheels 18 work together so that the corresponding second winding reel 20 can wind and unwind the sling 7, thereby allowing the furnace door body 3 to be opened and closed.

[0039] Please see Figure 5 Two drive belts 19 are provided above the mounting frame 1. The outer surface of each drive belt 19 is connected to the corresponding second winding reel 20 and drive wheel 18. The drive belts 19 enable the slings 7 on both sides of the furnace door body 3 to run synchronously, so that the furnace door body 3 is subjected to uniform force during opening and closing, and the opening and closing of the furnace door body 3 is more stable.

[0040] This embodiment of a rigid-sealed segmented furnace door replaces the traditional integral furnace door with a segmented furnace door formed by the combination of a left furnace door and a right furnace door. The lifting and lowering of one side of the furnace door is controlled by an independent suspension mechanism. By controlling the start and stop of the two first motors 8, the corresponding first winding reel 10 can be used for winding and unwinding. This allows for the lifting and adjustment of the door panel 5 on one side. The opening of the door panel 5 on one side can be reduced to minimize the opening of the furnace body, thus preventing a large amount of heat loss from the furnace and reducing the heat loss inside the furnace.

[0041] The working principle of the above embodiments is as follows:

[0042] When it is necessary to open or close the rigid-sealed segmented furnace door, the entire process starts with the start of the second motor 9. The start of the second motor 9 will drive the corresponding transmission wheel 18 to rotate, and through the meshing between the two gears 17, the two transmission wheels 18 will rotate synchronously in opposite directions. At this time, through the connection between the two transmission belts 19 and the corresponding transmission wheels 18 and the second winding reel 20, the start of the second motor 9 will drive the second winding reel 20 to wind up and unwind the lifting cable 7, thereby adjusting the height of the furnace door body 3. When a small amount of material needs to be added, the first motor 8 needs to be started. The first motor 8 will drive the corresponding first winding reel 10 to rotate, thereby winding up the chain 11. The left and right door panels 5 can be adjusted up and down through the chain 11. The adjustment of the height of the two door panels 5 can reduce the opening of the furnace body, avoid a large amount of heat loss in the furnace, and thus reduce the heat loss in the furnace.
