Description

Technical Field

[0001] The utility model relates to the technical field of sintering machines, in particular to a novel head and tail magnetic sealing device for a sintering machine. Background Art

[0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants, and is mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants.

[0003] During the use of the sintering machine, a head and tail 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 bellows at the head and tail of the sintering machine and the bottom beam of the trolley. The purpose is to overcome the shortcomings of the existing technology and provide a new sealing device, which can effectively realize the sealing of the head and tail of the trolley, reduce air leakage and reduce energy consumption.

[0004] However, in the prior art, the elastic support system inside the head and tail sealing devices of most sintering machines is prone to spring failure after long-term use, resulting in panel collapse, side air leakage and other problems. Utility Model Content

[0005] The utility model aims to at least solve the problem in the prior art that the supporting force decreases after the spring fails, which easily leads to the collapse of the panel.

[0006] This solution provides a new type of magnetic sealing device for the head and tail of a sintering machine, which is achieved by the following specific technical means: it includes a box-shaped base, a spring device and a floating upper box body. Multiple groups of the floating upper boxes are spliced ​​into a large top box cover to seal the top opening of the box-shaped base, and the upper and lower ends of the spring device are respectively connected to the top box cover and the box-shaped base; the side edges of the top box cover and the side edges of the box-shaped base are sealed by a retractable sealing member, so that when the top box cover moves up and down, it can maintain an airtight state between the side edges of the box-shaped base;

[0007] At the same time, the top surface of the top box cover is provided with a magnetic wear-resistant mechanism, which not only has the function of wear resistance, but also strengthens the support of the top cover plate through the magnetic connection between the top cover plate and the top cover plate.

[0008] Preferred technical solution 1: The side edges of the top plates of two adjacent groups of floating upper boxes are butted and fixed, and at the same time, the joints of the top plates of the two adjacent groups of floating upper boxes are sealed by a second sealing member.

[0009] Preferred technical solution two: The magnetic wear-resistant mechanism includes an assembly fixing frame and a wear-resistant plate. The side of the assembly fixing frame is fixed to the side of the top plate, and the wear-resistant plate is plug-welded on the assembly fixing frame. Strong magnets are embedded between two adjacent groups of the wear-resistant plates, and the assembly fixing frame and the top plate are magnetically attached by strong magnets.

[0010] Optimal technical solution three: There is a certain slope on both sides of the wear-resistant plate to ensure the smooth passage of the trolley.

[0011] Preferred technical solution four: The spring device includes a screw with the top end fixed to the floating upper box body, the bottom end of the screw rod extends out from the hole opened on the box-shaped base, and a nut is sleeved on the bottom end, and a high-temperature resistant support spring is sleeved on the screw rod and placed between the floating upper box body and the box-shaped base.

[0012] The above structure enables this solution to have the following beneficial effects:

[0013] 1. Sealing between the top box cover and the box base, and between two adjacent sets of top plates, can effectively prevent side air leakage after elastic failure;

[0014] 2. By setting up the magnetic wear-resistant mechanism, the magnetic wear-resistant mechanism can fully fit with the top plate, provide enhanced support for the top plate, and reduce the probability of the top plate collapsing. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3 A new type of magnetic sealing device for the head and tail of a sintering machine includes a box-type base 1, a spring device 2 and a floating upper box body 3. The bottom side of the box-type base 1 is welded and fixed to the sintering machine bracket. Multiple groups of floating upper boxes 3 are spliced ​​into a large top box cover to seal the top opening of the box-type base 1. The upper and lower ends of the spring device 2 are respectively connected to the top box cover and the box-type base 1 to elastically support the top box cover, so that the top box cover can move freely up and down under the support of the spring device 2.

[0023] The sides of the top cover and the sides of the box-shaped base 1 are sealed by a retractable seal 1 (4), so that when the top cover moves up and down, it can maintain an airtight state between the sides of the box-shaped base 1; the sides of the top plates of two adjacent groups of floating upper boxes 3 are connected and fixed by bolts and nuts after being butted together, and the joints of the top plates of the two adjacent groups of floating upper boxes 3 are sealed by a seal 2 (6);

[0024] At the same time, a set of magnetic wear-resistant mechanisms 5 is correspondingly provided on the top plate of each group of floating upper boxes 3. The magnetic wear-resistant mechanisms 5 not only have the function of wear resistance, but also strengthen the support of the top cover plate through the magnetic connection between the top plate of the floating upper box 3, effectively preventing the top cover plate from collapsing.

[0025] See also Figures 1-4 A new type of magnetic sealing device for the head and tail of a sintering machine. The magnetic wear-resistant mechanism 5 consists of an assembly fixing frame 51, a strong magnet 52, a stainless steel cover plate 53, and a wear-resistant plate 55. The side of the assembly fixing frame 51 and the side of the top plate are fixed by bolts and nuts. At the same time, multiple groups of wear-resistant plates 55 are welded to the assembly fixing frame 51 at intervals. The strong magnet 52 embedded between two adjacent groups of wear-resistant plates 55 is welded and compacted with a stainless steel cover plate 53. The strong magnet 52 is used to magnetically attach the assembly fixing frame 51 to the top plate. The wear-resistant plate 55 is machined with wear-resistant steel. Both sides of the wear-resistant plate 55 have a certain slope to ensure the smooth passage of the trolley. The top of the wear-resistant plate 55 protrudes from the top surface of the assembly fixing frame 51.

[0026] See also Figure 1 and Figure 3 A new type of magnetic sealing device for the head and tail of a sintering machine. The spring device 2 includes a screw 21 whose top is fixed to the floating upper box body 3. The bottom end of the screw 21 extends out of the hole opened on the box-type base 1 and a nut is sleeved on the bottom end. A high-temperature resistant support spring 22 is sleeved on the screw 21 and placed between the floating upper box body 3 and the box-type base 1. The length of the screw 21 extending out of the hole is controlled by turning the nut.

[0027] See also Figure 3-Figure 4 A new type of magnetic sealing device for the head and tail of a sintering machine is provided, wherein the limit card plate 54 fixed on the side of the assembly fixing frame 51 is inserted between the two sets of top plates.

[0028] Working Principle: First, the bottom surface of the box-shaped base 1 is welded to the sintering machine support. A spring device 2 lifts the magnetic wear-resistant mechanism 5, ensuring contact between the wear-resistant plate 55 and the bottom plate of the trolley. The magnetic wear-resistant mechanism 5 and the floating upper box 3 are designed in sections, ensuring a tight seal with the trolley. The new structure features three seals to ensure a tight seal.
