Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, and in particular to a sealing device for a sintering machine. Background Technology

[0002] In the steel smelting process, iron-containing raw materials, solvents, fuels and blast furnace return ore need to be mixed evenly in a certain proportion by a mixer, and then sintered into cake or block blast furnace clinker by a sintering machine for further processing.

[0003] The sintering machine requires a trolley to feed in the raw materials and discharge the clinker during production. Air leakage can occur during the sintering process, leading to increased energy consumption and reduced efficiency.

[0004] The existing sealing methods are iron-iron seal, iron-oil seal, and iron-sealant seal. Iron-iron and iron-oil seals have high failure rates and waste oil. Iron-sealant seals have short lifespans, are not wear-resistant, and have poor sealing performance.

[0005] Therefore, how to improve the sealing effect of sintering machine seals is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] The second sealing strip is installed on the top plate of the sintering air box and extends along the length of the exhaust port at the top of the sintering air box.

[0011] The first sealing strip and the second sealing strip are fitted together to form a dynamic seal.

[0012] Furthermore, a first channel steel is provided on the bottom plate of the sintering trolley, into which the first sealing strip is inserted, and the inner diameter of the first channel steel is adapted to the outer diameter of the first sealing strip.

[0013] Furthermore, a second channel steel is provided on the top plate of the sintering air box, into which the second sealing strip is inserted, and the inner diameter of the second channel steel is adapted to the outer diameter of the second sealing strip.

[0014] Furthermore, the first sealing strip and the second sealing strip have the same shape.

[0015] Furthermore, the cross-sectional dimensions of the first sealing strip are less than or equal to the cross-sectional dimensions of the second sealing strip.

[0016] Furthermore, the first sealing strip is arranged along the length and width of the ventilation opening at the bottom of the sintering trolley, and the second sealing strip is arranged along the length and width of the exhaust opening at the top of the sintering air box.

[0017] Furthermore, it also includes an elastic compensation component disposed within the first channel steel and the second channel steel, for providing elastic compensation for the first sealing strip and the second sealing strip.

[0018] Furthermore, the elastic compensation element is a spring or a rubber pad.

[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] This utility model discloses a sealing device for a sintering machine. Through the dynamic bonding design of the first sealing strip and the second sealing strip, it ensures that the sintering machine maintains good sealing performance during operation, effectively reduces air leakage, improves sintering efficiency, and reduces energy consumption.

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

[0030] In this embodiment of the utility model, a sealing device for a sintering machine is provided, such as... Figure 1 As shown, it includes a first sealing strip 1 and a second sealing strip 2.

[0031] Specifically, see Figures 1 to 3 The first sealing strip 1 is connected to the bottom plate 601 of the sintering trolley 6 and extends along the length of the ventilation opening 602 at the bottom of the sintering trolley 6. The second sealing strip 2 is disposed on the top plate 701 of the sintering air box 7 and extends along the length of the exhaust opening 702 at the top of the sintering air box 7. The first sealing strip 1 and the second sealing strip 2 are correspondingly fitted together, that is, the bottom surface of the first sealing strip 1 and the top surface of the second sealing strip 2 are sealed together, so that they fit together during the operation of the sintering machine to form a dynamic sealing structure.

[0032] To ensure a stable connection between the first sealing strip 1 and the second sealing strip 2 on the sintering trolley 6 and the sintering air box 7, in this embodiment, a first channel steel 3 is provided on the bottom plate 601 of the sintering trolley 6 for inserting the first sealing strip 1. The inner diameter of the first channel steel 3 is adapted to the outer diameter of the first sealing strip 1. Similarly, in this embodiment, a second channel steel is provided on the top plate 701 of the sintering air box 7 for inserting the second sealing strip 2. The outer diameter of the second sealing strip 2 is adapted to the inner diameter of the second channel steel.

[0033] The first sealing strip 1 and the second sealing strip 2 can be fixed to the first channel steel 3 and the second channel steel by means of bolts, direct embedding, or welding. Of course, other methods that can ensure the sealing strips are securely installed in the channel steel should also be covered within the scope of protection of this utility model.

[0034] In this embodiment, the shapes of the first sealing strip 1 and the second sealing strip 2 are consistent. The shape of the sealing strip can be a cylinder, a semi-cylinder, a cube, or a frustum, as long as the first sealing strip 1 and the second sealing strip 2 can play a good sealing role when they are mated together and there is no air leakage.

[0035] Furthermore, all the aforementioned sealing strips are made of non-fluid graphene. This is because graphene has certain high-temperature resistance and can withstand extremely high temperatures; moreover, the microstructure of graphene gives it excellent sealing properties, effectively preventing gas and liquid leakage. In addition, due to its good elasticity and wear resistance, it can adapt to the relative movement between the trolley and the bellows during the operation of the sintering machine, while maintaining stable sealing performance, effectively preventing gas leakage and extending the service life of the sealing strip.

[0036] In this embodiment, the cross-sectional size of the first sealing strip 1 is designed to be less than or equal to the cross-sectional size of the second sealing strip 2. This size design can reduce the friction between the first sealing strip 1 and the bottom plate of the sintering trolley 6 while ensuring the sealing effect, reduce the running resistance of the equipment, improve the operating efficiency of the sintering machine, and facilitate the installation and replacement of the sealing strip.

[0037] The first sealing strip 1 and the second sealing strip 2 can be arranged not only along the length of the vent 602 and the exhaust vent 702, but also simultaneously along both the length and width of the vent 602 and the exhaust vent 702. This forms a corresponding annular sealing structure around the vent 602 and the exhaust vent 702, achieving a comprehensive seal for the vent 602 at the bottom of the sintering trolley 6 and the exhaust vent 702 at the top of the sintering air box 7. This effectively prevents gas leakage from all directions, further improving the sealing performance and production efficiency of the sintering machine.

[0038] Furthermore, since the first channel steel 3 and the second channel steel are made of steel, to prevent the first sealing strip 1 and the second sealing strip 2 from being impacted during operation after being placed inside the channel steel, in this embodiment, elastic compensation components 5 are provided inside both the first channel steel 3 and the second channel steel. The elastic compensation components 5 provide elastic support for the first sealing strip 1 and the second sealing strip 2 when relative movement occurs between the sintering trolley 6 and the sintering air box 7, reducing the impact force on the sealing strips, further improving the service life and sealing performance stability of the sealing strips, while also reducing equipment operating noise and improving the working environment.

[0039] The elastic compensation component 5 can be set as a spring, a rubber gasket, or an elastic buffer layer can be directly coated on the inner wall of the channel steel, that is, coated with some flexible material to reduce the impact force on the sealing strip during operation, reduce the wear rate, and ensure the sealing performance.

[0040] The sintering machine sealing device disclosed in this utility model forms a dynamic seal through the corresponding fit of the first sealing strip 1 and the second sealing strip 2, ensuring that the sintering machine maintains good sealing performance during operation and effectively reducing air leakage. Furthermore, the cross-sectional dimensions of the first sealing strip 1 are designed to be smaller than or equal to the cross-sectional dimensions of the second sealing strip 2, ensuring a tight fit under different operating conditions, preventing air leakage, thereby reducing energy consumption and improving sintering efficiency.

[0041] In addition, the sealing strip is made of graphene non-fluid, which has high temperature resistance, good sealing properties, elasticity and wear resistance. It can adapt to the relative movement between the trolley and the air box during the operation of the sintering machine, while maintaining stable sealing performance and extending service life.

[0042] By using the first channel steel 3 and the second channel steel to fix the sealing strip, the sealing strip is installed firmly and is not easy to loosen, while also facilitating maintenance and replacement.

[0043] The elastic compensation element 5 can reduce the impact force on the sealing strip during operation, reduce equipment operating noise, and improve the working environment.

[0044] In summary, the sintering machine sealing device disclosed in this utility model significantly improves sealing performance, reduces energy consumption, enhances equipment stability and service life, and is easy to install and maintain, reduces operating noise, and has high economic efficiency and practicality.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
