Description

Technical Field

[0001] This utility model relates to the field of industrial furnace technology, and in particular to an industrial furnace door sealing enhancement device. Background Technology

[0002] In metallurgical furnaces, furnace door seals are designed to prevent the leakage of high-temperature gases, thereby improving furnace efficiency and safety. Furnace door sealing materials are typically high-temperature wear-resistant materials, such as high-temperature silicone, asbestos, and ceramics. The design and installation of furnace door seals must take into account factors such as furnace temperature, pressure, and gas composition to ensure effective sealing.

[0003] Chinese Patent No. CN214371738U discloses a furnace door sealing device for a metallurgical industrial furnace, including a furnace door and a pressing mechanism. The pressing mechanism is symmetrically installed on both sides of the furnace door. The furnace door includes an outer steel structure of the furnace door frame and a furnace door lining. The furnace door lining is connected to the outer steel structure of the furnace door frame. The furnace door lining is made of zirconium-containing ceramic fiber modules. The edge of the side of the furnace door lining away from the outer steel structure of the furnace door frame contacts the furnace top and side wall.

[0004] The above-mentioned patent has the following problems when in use: When the furnace door is closed, pressure is applied to the furnace door by the clamping mechanism on both sides, so that the furnace door is pressed against the furnace wall under the action of gravity to achieve a seal. However, in the high-pressure working environment inside the furnace, the pressure will press against the furnace door. When the pressure is greater than the pressure applied by gravity, leakage will still occur, which poses a certain safety hazard.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides an industrial furnace door sealing enhancement device, referring to... Figures 1-6 An industrial furnace door sealing enhancement device includes an industrial furnace inlet wall 1, a cylinder 3, and a sealing mechanism 4;

[0031] A bracket 2 is fixedly installed on the furnace opening wall 1 of the industrial furnace. Two cylinders 3 are fixedly installed on the bracket 2. The output ends of the two cylinders 3 are equipped with the same sealing mechanism 4. Side plates 5 are fixedly installed on both sides of the furnace opening wall 1 of the industrial furnace. The sealing mechanism 4 is connected to the two side plates 5.

[0032] The sealing mechanism 4 includes a transmission plate 41, a slider 42, a furnace door 43, a trapezoidal plate 44, a rack 45, a gear 46, a rotating shaft 47, a motor 48, and a sealing gasket 49. The output ends of the two cylinders 3 are fixedly connected to the transmission plate 41, and the two transmission plates 41 are slidably connected to the sliders 42. The same furnace door 43 is fixedly connected to the two sliders 42. The furnace door 43 abuts against the furnace opening wall 1 of the industrial furnace. Through the cooperative design between the cylinders 3, transmission plate 41, slider 42, spring 6, furnace door 43, sealing gasket 49, and sealing frame 7, the furnace opening wall 1 of the industrial furnace can be opened and closed automatically. Through the cooperative design between the motor 48, gear 46, rack 45, trapezoidal plate 44, and side plate 5, and driven by the cooperation between the two cylinders 3 and the motor 48, the furnace door 43 can be limited and fixed, and the sealing effect of the furnace door 43 on the furnace opening wall 1 of the industrial furnace can be enhanced.

[0033] In this method, a cavity is provided on the furnace door 43, and two trapezoidal plates 44 are slidably connected in the cavity. The two trapezoidal plates 44 abut against the two side plates 5 respectively. Through the interaction between the two trapezoidal plates 44 and the two side plates 5, the furnace door 43 can be limited.

[0034] In this method, a sealing gasket 49 is fixedly installed on one side of the furnace door 43, and a sealing frame 7 is sealed inside the furnace opening wall 1 of the industrial furnace. The sealing gasket 49 abuts against the sealing frame 7 to improve the sealing performance of the furnace door 43 to the furnace opening wall 1 of the industrial furnace. Both the sealing frame 7 and the sealing gasket 49 are alumina ceramics.

[0035] In this configuration, two racks 45 are slidably connected within the cavity. One end of each rack 45 is fixedly connected to two trapezoidal plates 44. The same gear 46 meshes between the two racks 45. A rotating shaft 47 is fixedly connected to the gear 46 and is rotatably connected to the furnace door 43. The two racks 45 are located on opposite sides of the gear 46, so that during the transmission between the gear 46 and the two racks 45, the two racks 45 move in opposite directions.

[0036] In this configuration, a motor 48 is fixedly installed on one side of the furnace door 43, and the output end of the motor 48 is fixedly connected to the rotating shaft 47 to drive the gear 46.

[0037] In this method, the top and bottom of the sealing gasket 49 are provided with ramp 1, and the sealing frame 7 is provided with two ramp 2. The two ramp 2 are adapted to the two ramp 1. Through the cooperation between the two ramp 1 and the two ramp 2, the sealing gasket 49 can be automatically moved out and into the furnace opening wall 1 of the industrial furnace during the process of the two cylinders 3 driving the furnace door 43 upward and downward.

[0038] In this method, each of the two transmission plates 41 is provided with a sliding groove, and the two sliders 42 slide in the two sliding grooves respectively. A spring 6 is fixedly installed in each of the two sliding grooves, and one end of the two springs 6 is fixedly connected to the two sliders 42 respectively. Through the elastic potential energy of the two springs 6 and the transmission of the two sliders 42 and the furnace door 43, the sealing gasket 49 can be automatically moved into the furnace opening wall 1 of the industrial furnace.

[0039] In this method, slots are provided on both side plates 5 and correspond to the two trapezoidal plates 44 respectively, so as to facilitate the connection between the two trapezoidal plates 44 and the two side plates 5.

[0040] Working principle: In use, firstly, the motor 48 drives the rotating shaft 47 to rotate on the furnace door 43. At the same time, the rotating shaft 47 drives the gear 46 to rotate synchronously. Meanwhile, the gear 46 meshes with the two racks 45, so that the two racks 45 drive the two trapezoidal plates 44 to slide on the furnace door 43, and disengage the two trapezoidal plates 44 from the slots on the two side plates 5. The two trapezoidal plates 44 are then stored in the cavity on the furnace door 43, thereby achieving the effect of contacting and limiting the furnace door 43.

[0041] Subsequently, the furnace door 43 moves upward through the synchronous drive of the two cylinders 3 and the transmission of the two transmission plates 41 and the slider 42. The furnace door 43 drives the sealing gasket 49 to move synchronously. During this process, since the top and bottom of the sealing gasket 49 are provided with ramp 1, and both sides of the sealing frame 7 are provided with ramp 2, the interaction between the ramps and ramp 2 causes the sealing gasket 49 to move to one side a certain distance. At the same time, the transmission of the furnace door 43 causes the two sliders 42 to slide a certain distance on the two transmission plates 41, and the two springs 6 are further compressed, thereby achieving the purpose of the two cylinders 3 driving the furnace door 43 to disengage from the furnace opening wall 1 of the industrial furnace. This achieves the effect of opening the furnace opening wall 1 of the industrial furnace; conversely, it achieves the effect of limiting and sealing the furnace opening wall 1 of the industrial furnace. When the sealing gasket 49 corresponds to the sealing frame 7, the elastic potential energy of the two springs 6 and the transmission of the two sliders 42 cause the sealing gasket 49 to contact the sealing frame 7, and the two trapezoidal plates 44 to correspond to the slots on the two side plates 5. Through the interaction between the inclined surfaces of the two trapezoidal plates 44 and the slots on the two side plates 5, the furnace door 43 and the furnace opening wall 1 of the industrial furnace are tightly fitted together, and the sealing gasket 49 and the sealing frame 7 are tightly fitted together, thus achieving the effect of limiting the furnace door 43.

[0042] The technological advancement of this invention compared to the prior art is that, through the cooperation of various components, not only can the furnace door 43 achieve the effect of automatically sealing the industrial furnace opening wall 1, but the furnace door 43 can also be further limited, thereby enhancing the sealing performance of the industrial furnace opening wall 1 and greatly improving safety and practicality.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
