Description

Technical Field

[0001] This utility model relates to a sealing device, and in particular to a flexible magnetic sealing device for the head and tail of a sintering machine used in the field of sintering machine sealing. Background Technology

[0002] The sintering machine is suitable for sintering operations in large ferrous metallurgical sintering plants. It is mainly suitable for the sintering of iron ore powder in large and medium-sized sintering plants. During the use of the sintering machine, the end sealing device of the sintering machine is required. The end sealing device of the sintering machine is mainly used to control air leakage between the air box at the head and tail of the sintering machine and the bottom beam of the trolley.

[0003] The specification of Chinese Patent Publication No. CN218065923U discloses an end sealing device for a sintering machine. In this utility model, the end seal has a good sealing effect. Through the groove, the protrusion and the first bolt, it is convenient to splice multiple wear-resistant sealing upper panels and to connect the wear-resistant sealing upper panels to the upper box. Through the screw, nut, support plate, spring and fourth bolt, it can make the wear-resistant sealing upper panel in close contact with the trolley and have a conforming effect. It can also adjust the height of the pad plate upward to prevent the panel from collapsing due to the failure of the spring after long-term use. Furthermore, through the interlocking U-shaped sealing leaf spring, the interlocking plate and the PTFE cloth, it plays a supporting role and prevents air leakage in the middle part.

[0004] However, the above patent will still have the following problems in actual application: The wear-resistant sealing upper panel in the above patent is made of rigid material. After the bottom of the trolley is heated and deformed, if the rigid material is in direct contact with the trolley, it will cause a gap between the bottom of the trolley and the wear-resistant sealing upper panel, which will cause cold air to enter the sintering machine cavity, thereby affecting the normal production of sintering and increasing the energy consumption of the blower. Utility Model Content

[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the wear-resistant sealing upper panel in the existing patent is made of rigid material. When the bottom of the trolley is heated, it will deform, resulting in a gap between the bottom of the trolley and the wear-resistant sealing upper panel. This allows cold air to enter the sintering machine cavity, affecting the normal production of sintering and increasing the energy consumption of the blower.

[0006] To solve the above problems, this utility model provides a flexible magnetic sealing device for the head and tail of a sintering machine, including a base. Two side sealing plates and two mounting brackets are fixedly connected to the upper and lower ends of the base, respectively. Multiple elastic components are movably connected through the lower end of the base. The upper ends of the multiple elastic components are all fixedly connected to an upper sealing plate. Two baffles are fixedly connected to the lower end of the upper sealing plate. An mounting plate is fixedly connected to the upper end of the upper sealing plate. Two mounting strips, multiple magnetic strips, and sealing strips are fixedly connected to the upper end of the mounting plate. The multiple magnetic strips and multiple sealing strips are staggered and located between two mounting strips. The sealing strips are elastic. The elastic components include a compression spring fixedly connected to the upper end of the base. A sliding plate is fixedly connected to the upper end of the compression spring. A sliding rod is threaded through the lower end of the base. The upper end of the sliding rod movably passes through the compression spring and the sliding plate in sequence. An end is inserted into the upper end of the sliding rod. The upper end of the end is fixedly connected to the lower end of the upper sealing plate.

[0007] In the aforementioned flexible magnetic sealing device for the head and tail of the sintering machine, after the trolley is deformed by heat, the iron powder generated in the gap is attracted by the magnetic strip, causing the iron powder to accumulate in the gap. This forms a flexible sealing layer between the trolley and the sealing device, allowing the trolley to maintain the sealing effect it had when it was not deformed, even when deformed. The structure is simple and easy to install, effectively solving the air leakage problem at the head and tail of sintering and pelletizing production equipment, improving the production efficiency of sintering and pelletizing production equipment, improving product quality, and reducing the energy consumption and maintenance costs of the blower.

[0008] As a further improvement of this application, the ends of the two baffles that are far apart are respectively attached to the adjacent side sealing plates, and the height of the side sealing plates is greater than the height of the baffles.

[0009] As a further improvement to this application, two mounting brackets are located at the front and rear ends of the base, respectively, and the mounting brackets are U-shaped, with chamfers provided at the ends of the two mounting strips that are far apart.

[0010] As a further improvement of this application, the front end of the mounting plate is fixedly connected to two mounting rods, which are L-shaped.

[0011] As another improvement of this application, the mounting plate has a hollow structure, and a cooling pipe is fixedly connected to the inner cavity of the mounting plate. Both ends of the cooling pipe are fixedly connected to an external pipe through the mounting plate.

[0012] As a further improvement to this application, the cooling pipe has a serpentine structure, the outer connecting pipe is a telescopic flexible hose, and the two outer connecting pipes are located on the left and right sides of the mounting plate, respectively.

[0013] In summary, during practical applications, after the trolley deforms due to heat, a gap appears between the mounting plate and the trolley. Because there is iron powder in the gap, multiple magnetic strips attract the iron powder, causing it to accumulate within the gap. This creates a flexible sealing layer between the trolley and the sealing device, allowing the trolley to maintain its sealing effect even when deformed. Multiple magnetic strips can attract iron powder according to the deformation location of the trolley's bottom beam, effectively reducing air leakage. The two magnetic strips are connected by an elastic sealing strip, preventing air leakage and material jamming. The lower elastic component allows for height adjustment of the upper sealing plate, ensuring the magnetic strips follow the trolley's bottom plate and maintain close contact, thus effectively improving the sealing effect.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1 , Figure 2 , Figure 3and Figure 4 The diagram shows a flexible magnetic sealing device for the head and tail of a sintering machine, comprising a base 1. Two side sealing plates 2 and two mounting brackets 3 are fixedly connected to the upper and lower ends of the base 1, respectively. The two mounting brackets 3 are located at the front and rear ends of the base 1, and are U-shaped. Multiple elastic components movably pass through the lower end of the base 1. An upper sealing plate 4 is fixedly connected to the upper end of the multiple elastic components. Two baffles 16 are fixedly connected to the lower end of the upper sealing plate 4. The ends of the two baffles 16 that are far apart are respectively abutted against the adjacent side sealing plates 2, effectively reducing air leakage. The height of the side sealing plates 2 is greater than the height of the baffles 16. A mounting plate 5 is fixedly connected to the upper end of the upper sealing plate 4. The front end of the mounting plate 5 is fixed... The mounting plate 5 has two mounting rods 13, which are L-shaped. The upper end of the mounting plate 5 is fixedly connected to two mounting strips 6, multiple magnetic strips 7, and sealing strips 8. The ends of the two mounting strips 6 that are far apart are chamfered. The multiple magnetic strips 7 and multiple sealing strips 8 are staggered and located between the two mounting strips 6. The sealing strips 8 are elastic and attract iron powder through the multiple magnetic strips 7, so that the iron powder accumulates in the gaps. This forms a flexible sealing layer between the trolley and the sealing device, so that the trolley can maintain the sealing effect when it is not deformed even when it is deformed. The sealing strips 8 prevent air leakage and material jamming between the two magnetic strips 7.

[0026] Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown: The elastic component includes a compression spring 9 fixedly connected to the upper end of the base 1. A slide plate 10 is fixedly connected to the upper end of the compression spring 9. A slide rod 11 is threaded through the lower end of the base 1. The upper end of the slide rod 11 moves through the compression spring 9 and the slide plate 10 in sequence. An end head 12 is inserted into the upper end of the slide rod 11. The upper end of the end head 12 is fixedly connected to the lower end of the upper sealing plate 4. When the trolley passes through a foreign object and causes the upper sealing plate 4 to move downward, the end head 12 moves downward and squeezes the slide plate 10, thereby compressing the compression spring 9 downward. After the trolley is used, the upper sealing plate 4 is reset under the action of the compression spring 9.

[0027] When using this sealing device, after the trolley deforms due to heat, a gap appears between the mounting plate 5 and the trolley. Since there is iron powder in the gap, multiple magnetic strips 7 adsorb the iron powder, causing it to accumulate in the gap. This forms a flexible sealing layer between the trolley and the sealing device, allowing the trolley to maintain its sealing effect even when deformed. The multiple magnetic strips 7 can adsorb iron powder according to the deformation position of the trolley's bottom beam, effectively reducing air leakage. The two magnetic strips 7 are connected by an elastic sealing strip 8, making it less likely for air leakage and material jamming to occur between them. The elastic component below can adjust the height of the upper sealing plate 4, allowing the magnetic strips 7 to follow the bottom plate of the trolley, ensuring that the sealing device and the bottom plate of the trolley remain in close contact, thereby effectively improving the sealing effect.

[0028] Second implementation method:

[0029] This embodiment adds a cooling pipe 14 and an external pipe 15 to the first embodiment, while the rest remains the same as the first embodiment.

[0030] Figure 7 As shown: the mounting plate 5 has a hollow structure, and a cooling pipe 14 is fixedly connected to the inner cavity of the mounting plate 5. Both ends of the cooling pipe 14 are fixedly connected to the mounting plate 5 and external connecting pipes 15. The cooling pipe 14 has a serpentine structure, so that the coolant in the cooling pipe 14 can cool down multiple magnetic strips 7. The external connecting pipe 15 is a telescopic hose, and the two external connecting pipes 15 are located on the left and right sides of the mounting plate 5, respectively, so that the mounting plate 5 can move with the movement of the upper sealing plate 4.

[0031] Even after the trolley deforms due to heat, the sealing device remains in contact with the trolley via the magnetic strip 7. However, excessively high temperatures at the bottom of the trolley may weaken the magnetism of the magnetic strip 7. In this case, coolant can be introduced through the cooling pipe 14 to cool down the multiple magnetic strips 7, thereby effectively preventing the weakening of the magnetism of the magnetic strip 7 and effectively extending the service life of the sealing device.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
