Problems solved by technology

[0003] 1. The airtight box placed on the sintering trolley itself has the problem of air leakage; it is often caused by the sinter powder blocking the sliding plate, which causes a large gap between the sliding plate and the sliding plate, causing more serious air leakage
[0004] 2. It cannot prevent the air leakage that occurs at the end face of the adjacent sintering trolley

Embodiment 1

[0028] Example 1, such as Figure 1 to Figure 7 shown.

[0029] figure 1 It is the front view of Embodiment 1 of the present invention, which is to observe the device of the present invention from the side of the sintering machine, to express the general outline of this embodiment.

[0030] From figure 1 It can be seen from the figure that this embodiment is divided into 3 large sections: 1 is the front sealing section, the length of this section is M, and the value of M is recommended to be 1.5 to 3 times the width of the trolley. In this section, there are also Longitudinal sealing body; 2 is the middle sealing section; 3 is the rear sealing section, the length of this section is N, and the value of N is also 1.5 to 3 times the width of the trolley, and a longitudinal sealing body is also arranged in this section. 4 and 5 are the interface between the front end sealing section 1 and the rear end sealing section 3 and the middle sealing section 2 respectively. And the a...

Embodiment 2

[0037] Example 2, such as Figure 8 ~ Figure 12 shown.

[0038] Figure 8 It is the front view of this embodiment, and it also observes the device of the present invention from the side of the sintering machine to express the overall overview of this embodiment. This embodiment has been changed on the basis of Embodiment 1, and the main differences between this embodiment and Embodiment 1 are:

[0039]1. The shape and placement of the strip metal plate 7 are different. In this embodiment, the band-shaped metal plate 7 is in the shape of an annular band, and is supported by a pulley 19, and the pulley 19 may also function as a tensioning pulley if necessary.

[0040] 2. A pressure roller 20 is arranged above the band-shaped metal plate 7 placed between the sealing surfaces 13 and 15 . When necessary, a support pulley (not shown) can also be provided for the belt-shaped metal plate 7 above the pulley 19 .

[0041] 3. The limit baffle 21 of the strip metal plate 7 is set.

Embodiment 3

[0045] Example 3, such as Figure 13 and Figure 14 shown.

[0046] Figure 13 It is the front view of this embodiment, and it also observes the device of the present invention from the side of the sintering machine to express the overall overview of this embodiment. This embodiment is a change made on the basis of Embodiment 1 and Embodiment 2. The main differences between this embodiment and Embodiment 1 and Embodiment 2 are:

[0047] The shape of strip metal plate 7 is different with laying way. In this embodiment, the strip-shaped metal plate 7 is in a simple strip shape, and the strip-shaped metal plate 7 is fixed at one end close to the distributor of the sintering machine. In this embodiment, the band-shaped metal plate 7 is fixed by using a fixing beam 22 , a pressing plate 23 and screws 24 . In order to see its specific fixed structure clearly, the Figure 13 The magnified plot of part R in Figure 14 in; since its structure can already be obtained from Figur...

Abstract

The invention discloses a side sealing device of a sintering machine, belonging to the technical field of sealing of the sintering machine. The side sealing device is characterized in that a sealing cover is arranged between the outer side of a fence plate of a sintering pallet and an air box of the sintering machine; the fence plate of the sintering pallet and the sealing cover are respectively provided with a sealing surface; the sealing surfaces are coplanar and are approximately horizontal plane; and a stripy metal with the thickness being less than or equal to 4mm is arranged between the sealing surfaces. The side sealing device disclosed by the invention is applicable in sintering widely applied in the metallurgical industry, and has the advantages that the air leaking amount of the position adjacent to the end surface and the position of a sealing box can be obviously reduced, the power of a main exhaust fan of the sintering machine is reduced and the energy conservation is realized or the performance of the sintering machine is improved.

Description

technical field [0001] The invention relates to a side sealing device of a sintering machine, belonging to the technical field of sintering machine sealing. Background technique [0002] Sintering machine is a kind of equipment widely used in metallurgical enterprises. The air leakage rate of the sintering machine is generally as high as 50%, or even higher. The sealing device of the existing sintering machine is divided into two parts: the end sealing device and the side sealing device, wherein the side sealing device is usually composed of a sealing box with a swimming plate-sliding plate structure placed on the sintering trolley and Consists of fixed slides. The main problems with existing side seals are: [0003] 1. The sealed box placed on the sintering trolley itself has the problem of air leakage; it is often caused by a large gap between the sliding plate and the sliding plate due to the sinter powder blocking the sliding plate, which causes more serious air leaka...
