Description

Technical Field

[0001] This utility model relates to the field of annealing furnace door technology, and in particular to a sealing structure for an annealing furnace door. Background Technology

[0002] Annealing furnace door sealing structures are commonly used in various types of annealing furnaces, such as box-type, pit-type, and trolley-type furnaces. Their function is to prevent high-temperature gases inside the furnace from leaking out and outside air from entering, maintain a stable protective atmosphere inside the furnace, reduce heat loss, ensure uniform annealing temperature, prevent workpiece oxidation, reduce energy consumption, extend equipment life, and ensure that the mechanical properties and surface quality of the annealed workpieces meet the standards.

[0003] In practical applications, the existing annealing furnace door sealing structure, through the use of elastic seals and clamping devices, can meet the basic requirements for workpiece processing, but the following problems still exist:

[0004] Common annealing furnaces typically use compression seals. However, when the furnace door is opened and closed, the seal continuously rubs and squeezes against the side of the furnace door, leading to increased local damage and edge tearing, which affects the sealing effect. Therefore, this application provides an annealing furnace door sealing structure to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sealing structure for the furnace door of an annealing furnace.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an annealing furnace door sealing structure, comprising a mounting plate and a furnace door body disposed on the side of the mounting plate, and further comprising:

[0007] A sealing assembly, the sealing assembly including a gear disposed in the inner cavity of a mounting plate, a wheel disk meshing with the side of the gear, a first connecting plate disposed on the side of the wheel disk, and a sealing element disposed at one end of the first connecting plate;

[0008] A limiting component, the limiting component including a sliding plate disposed on the side of the first connecting plate.

[0009] Furthermore, a guide groove is provided on the side of the wheel.

[0010] The technical effect of adopting the above technical solution is that by opening the guide groove, the connecting rod can be made to reciprocate and translate when the wheel rotates clockwise.

[0011] Furthermore, a connecting rod is slidably connected to the inner cavity of the guide groove, and one end of the connecting rod is fixedly connected to the side of the first connecting plate.

[0012] The technical effect of adopting the above technical solution is that by setting a connecting rod, the first connecting plate can be supported.

[0013] Furthermore, a second connecting plate is connected to the side of the first connecting plate near the seal.

[0014] The technical effect of adopting the above technical solution is that by setting a second connecting plate, the sealing element can be driven to move synchronously.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] A drive motor is installed on the side of the gear. The output end of the drive motor is fixedly connected to the side of the gear through a connecting shaft. By starting the drive motor, the gear can drive the wheel to rotate counterclockwise. When the wheel rotates counterclockwise, it can cause the first connecting plate to move the seal back and forth through the guide groove. This can actively control the contact state between the seal and the side of the furnace door. By changing the movement mode of the seal, friction and squeezing between the furnace door and the seal can be avoided when the furnace door is opened and closed, which would affect the normal operation of the seal.

[0025] 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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: an annealing furnace door sealing structure, including a mounting plate 1 and a furnace door body 11 disposed on the side of the mounting plate 1, and further including:

[0027] The sealing assembly 2 includes a gear 21 disposed in the inner cavity of the mounting plate 1, a wheel 22 meshing with the side of the gear 21, a first connecting plate 24 disposed on the side of the wheel 22, and a sealing element 26 disposed at one end of the first connecting plate 24.

[0028] The limiting component 3 includes a sliding plate 31 disposed on the side of the first connecting plate 24. A guide groove 23 is provided on the side of the wheel 22, and a connecting rod 25 is slidably connected to the inner cavity of the guide groove 23. One end of the connecting rod 25 is fixedly connected to the side of the first connecting plate 24. A second connecting plate 27 is connected to the side of the first connecting plate 24 near the seal 26. A buffer layer 28 is provided in the inner cavity of the seal 26, and a splicing structure is provided at the edge of the seal 26 to ensure the effectiveness of the seal. By additionally providing a complete sealing gasket on the side of the buffer layer 28, it can effectively seal the furnace door body 11 in conjunction with the seal 26. By starting the drive motor disposed on the side of the gear 21, the output shaft of the motor rotates forward, thereby enabling the gear 21 to pass through. 1. The wheel 22 rotates counterclockwise. When the wheel 22 rotates counterclockwise, the connecting rod 25 is pushed to move towards the middle of the wheel 22 through the guide groove 23. During the movement of the guide groove 23, the second connecting plate 27 and the sealing element 26 can move synchronously through the first connecting plate 24. When the sealing element 26 moves to a certain position, the side of the buffer layer 28 contacts the outer surface of the furnace door body 11, thereby achieving the effect of sealing the side of the furnace door. Similarly, by driving the gear 21 in the opposite direction, the sealing element 26 can be disengaged and moved away from the outer surface of the furnace door body 11, thereby avoiding friction and squeezing of the sealing element 26 when the furnace door is opened and closed, effectively improving the service life and ensuring the sealing stability.

[0029] Furthermore, such as Figure 4As shown: A limiting plate 32 is provided at one end of the sliding plate 31. The side of the limiting plate 32 is fixedly connected to the inner cavity of the mounting plate 1. Through the cooperation of the sliding plate 31 and the limiting plate 32, the movement trajectory of the connecting rod 25 can be limited when it moves, so as to ensure the smooth operation of the sealing element 26.

[0030] Working principle:

[0031] like Figure 1-4 As shown:

[0032] In use: With the seal 26 in an open state, first manually close the furnace door body 11, then start the drive motor located on the side of the gear 21. The motor's output shaft rotates clockwise, thus driving the wheel 22 to move counter-clockwise via the gear 21. As the wheel 22 moves counter-clockwise, the guide groove 23 causes the connecting rod 25 to move the second connecting plate 27 and the seal 26 towards the side of the furnace door body 11. When the seal 26 reaches a certain position, the side of the buffer layer 28 contacts the outer surface of the furnace door body 11. The two ends of the sealing element 26 are spliced ​​together, thereby sealing the connection between the furnace door body 11 and the furnace body. Similarly, when the furnace needs to be opened, the drive motor is restarted, which drives the wheel 22 to rotate clockwise through the gear 21. This achieves the effect of moving the sealing element 26 and the buffer layer 28 away from the outer surface of the furnace door body 11. By changing the way the sealing element 26 and the buffer layer 28 are released from the seal, the frequent contact and squeezing between the furnace door body 11 and the sealing element 26 and the buffer layer 28 during opening and closing can be avoided, effectively improving the service life of the sealing structure.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
