Description

Technical Field

[0001] The present application relates to the technical field of walking beam furnaces, and in particular to a protective device and a walking beam furnace. Background Art

[0002] During the use of the walking beam furnace, the fixed bed and the moving bed of the walking beam furnace move relative to each other. Long-term movement and wear will cause a gap between the fixed bed and the moving bed, resulting in positive pressure inside the furnace, and the flames in the furnace are easy to jump out from the gap. The existing walking beam furnaces use brickwork and water jackets to block the gap, which is difficult to ensure good sealing, and the long-term flames will increase energy consumption. Summary of the invention

[0003] Based on this, it is necessary to provide a protective device and a stepping furnace to address the above problems. The protective device has a simple structure, good sealing effect, and reduces energy consumption.

[0004] The present invention provides a protective device, comprising:

[0005] A protection box, the protection box is used to be fixedly mounted on the fixed bed of the walking furnace to contain particulate matter; and

[0006] A protective plate, the protective plate having a fixed end and a free end extending from the fixed end along the direction of the protective box, the fixed end of the protective plate is used to be fixed to the moving bed of the stepping furnace, and the free end of the protective plate is inserted into the protective box, so that when the moving bed moves relative to the fixed bed, the free end of the protective plate is always immersed in the particles in the protective box to block the gap between the moving bed and the fixed bed.

[0007] In this arrangement, a protective box is fixed to the fixed bed of the stepping furnace to hold granular matter, a protective plate is inserted into the granular matter in the protective box, and the protective plate includes a fixed end and a free end, wherein the fixed end of the protective plate is fixed to the moving bed of the stepping furnace, so that when the moving bed moves relative to the fixed bed, the protective plate moves along with the moving bed in the granular matter of the protective box to seal the gap between the moving bed and the fixed bed, and further, the free end of the protective plate is inserted into the protective box and is always immersed in the granular matter in the protective box to prevent the free end of the protective plate from leaving the granular matter to create a gap when the moving bed moves up and down, causing the flame to jump out of the stepping furnace.

[0008] In one embodiment of the present invention, the free end portion of the protection plate extends from the fixed end portion in a front-rear manner to extend into the protection box.

[0009] With such arrangement, the free end of the protection plate extends forward and backward gradually from the fixed end to extend into the protection box, so as to reduce the friction generated by the movement between the free end and the particles in the protection box, thereby facilitating the flexible movement of the movable bed.

[0010] In one embodiment of the present invention, the front side of the free end of the protective plate is flush with the front side of the fixed end; the rear side of the free end extends obliquely from the rear side of the fixed end to the front side of the free end.

[0011] In this way, the front side surface of the free end of the protective plate is flush with the front side surface of the fixed end, forming the longest surface in contact with the particle, ensuring that the protective plate is always in contact with the particle, and the rear side surface of the free end extends obliquely from the rear side surface of the fixed end to the front side surface of the free end, forming the shortest surface in contact with the particle, reducing the resistance of the protective plate when inserting into the particle, and facilitating the smooth insertion of the free end of the protective plate into the particle.

The adjustable insulation component includes an insulation part and an adjustment mechanism, and the insulation part is movably arranged at the discharge end of the fixed bed, so that when discharging, the insulation part can be adjusted to move upward to send the material on the movable bed to the discharge end. In addition, the adjustment mechanism is arranged on the insulation part, which is used to adjust the position of the insulation part, adjust the insulation part to move left and right to reduce the gap between the insulation part and the movable bed, and adjust the insulation part to move up and down so as to fill the gap and send out the material at the same time.

[0014] In one embodiment of the present invention, the number of the thermal insulation components is three, wherein two of the thermal insulation components are respectively arranged on both sides of the movable bed, and one of the thermal insulation components is arranged on the front side of the movable bed.

[0015] In this way, two insulation parts are respectively arranged on both sides of the moving bed, so that when the moving bed and the fixed bed move relative to each other and wear and tear to produce a large gap, the insulation parts on both sides can be adjusted to fill the gap. One insulation part is arranged on the front side of the moving bed, so that when the moving bed moves backward, the insulation part on the front side can be adjusted to be close to the moving bed to prevent flames from the front end of the moving bed.

[0016] In one embodiment of the present invention, the adjustment mechanism includes a first adjustment component, which is arranged on the outside of the thermal insulation component and is used to adjust the position of the thermal insulation component left and right to reduce the gap between the thermal insulation component and the movable bed.

[0017] In this way, the adjustment mechanism includes three first adjustment components and a second adjustment component, and is connected to the three insulation parts one by one. Among them, the first adjustment component is arranged on the outside of the insulation part to adjust the left and right movement of the insulation part, reduce the gap between the insulation part and the moving bed, and prevent flames from bursting out of the gap.

[0035] Optionally, the protective device also includes an adjustable insulation component 30, which includes an insulation part 31 and an adjustment mechanism 32. When the movable bed 50 and the fixed bed 40 are worn due to relative movement and the gap becomes larger, the adjustment mechanism 32 adjusts the insulation part 31 to move left and right to reduce the gap and prevent the fire from bursting out.

[0036] Specifically, the protective plate 20 has a fixed end 21 and a free end 22, and the free end 22 extends from the fixed end 21 along the direction of the protective box 10, wherein the fixed end 21 is fixed to the movable bed 50, and the free end 22 is inserted into the protective box 10, so that when the movable bed 50 and the fixed bed 40 move relative to each other, the free end 22 of the protective plate 20 is always immersed in the particles 11 in the protective box 10 to block the gap between the movable bed and the fixed bed to prevent the fire from escaping from the stepping furnace.

[0037] Optionally, the granular material 11 may be, but is not limited to, implemented as sand.

[0038] Technicians in the relevant field should understand that when the protective device is used on a walking furnace, it is installed between the movable bed 50 and the fixed bed 40 of the walking furnace, and the movable bed 50 and the fixed bed 40 perform relative movement. Since this part is not the focus of the present invention, it will not be explained in the subsequent description.

[0039] In one embodiment, if Figures 1 to 4 As shown, the free end portion 22 of the protection plate 20 extends from the fixed end portion 21 in a tapered manner to extend into the protection box 10 so as to move along with the movable bed 50 .

[0040] Optionally, the front side of the free end 22 of the protective plate 20 is flush with the front side of the fixed end 21, ensuring that when the movable bed 50 and the fixed bed 40 move relative to each other, the protective plate 20 fixed on the movable bed 50 is always immersed in the granular material 11, and the rear side of the free end 22 of the protective plate 20 extends obliquely from the rear side of the fixed end 21 to the front side of the free end 22, which is convenient for reducing resistance when the protective plate 20 is inserted into the granular material 11. In addition, when the protective plate 20 moves with the movable bed 50, the friction force is reduced, which is conducive to the flexible movement of the movable bed 50. However, it is not limited to this, the front side of the free end 22 can be designed as an inclined surface symmetrical to the rear side, which is convenient for reducing resistance when the protective plate 20 moves up and down and forward and backward with the movable bed 50, and reducing the energy consumption loss of movement.

[0041] In one embodiment, if Figures 1 to 4 As shown, the protective device further includes an adjustable insulation component 30 for sealing the gap caused by the relative movement of the movable bed 50 and the fixed bed 40. Specifically, the adjustable insulation component 30 includes an insulation part 31 and an adjustment mechanism 32, and the adjustment mechanism 32 adjusts the insulation part 31 to seal the gap.

[0042] Furthermore, the insulation component 31 can be movably arranged at the discharge end of the fixed bed 40, and the adjusting mechanism 32 is arranged on the insulation component 31. Specifically, the adjusting mechanism 32 includes three first adjusting components 321 and second adjusting components 322, so that when the movable bed 50 and the fixed bed 40 move relative to each other to generate a wear gap, the first adjusting component 321 is arranged on the outside of the insulation component 31 to adjust the insulation component 31 to move left and right, and block the gap between the movable bed 50 and the fixed bed 40 in the left and right directions. The second adjusting component 322 is arranged at the end of the insulation component 31 to adjust the insulation component 31 to move up and down, and block the gap between the movable bed 50 and the fixed bed 40 in the up and down directions, thereby blocking the furnace fire from escaping from the furnace and preventing the material on the movable bed 50 from leaking from the gap between the movable bed 50 and the fixed bed 40 in the left and right directions.

[0043] In one embodiment, if Figures 1 to 4 As shown, there are three insulation components 31, two of which are respectively arranged on both sides of the movable bed 50 to block the gap between the movable bed 50 and the fixed bed 40 in the left and right directions, and one insulation component 31 is arranged on the front side of the movable bed 50 to block the gap between the movable bed 50 and the fixed bed 40 in the front and rear directions. The three insulation components 31 can be moved left and right to block the gap between the movable bed 50 and the fixed bed 40 caused by the wear of the side and front ends. In addition, the insulation components 31 can be made of rubber and polyvinyl chloride as the main materials, which have good heat resistance and wear resistance. When the insulation components 31 block the gap between the movable bed 50 and the fixed bed 40, it is ensured that the insulation components 31 are not easily damaged by high temperature. However, it is not limited to this, and the insulation components 31 can use different materials according to different stepping furnaces.

At the same time, leakage of materials on the movable bed 50 from the gaps is prevented. The second adjusting component 322 is provided with a second fastening bolt 3221. The second fastening bolt 3221 is adjusted to adjust the up and down movement of the thermal insulation component 31 to block the up and down gaps between the movable bed 50 and the fixed bed 40.

[0045] In one embodiment, if Figures 1 to 4 As shown, an insulation component 31 is arranged on the front side of the movable bed 50, and the insulation component 31 is provided with a slag discharge port 311 and a door 312 that can be flipped open. When the slag discharge port 311 is discharging slag, the door 312 is flipped open. When the slag discharge port 311 stops discharging slag, the door 312 covers the slag discharge port 311. At this time, the insulation component 31 is used to seal the gap between the movable bed 50 and the fixed bed 40.

[0047] The protective principle of the protective device for a walking beam furnace provided by the present invention is as follows: the moving bed 50 of the walking beam furnace moves relative to the fixed bed 40. When the moving bed 50 starts to transport materials, the protective plate 20 moves forward and backward and up and down with the moving bed 50. A protective box 10 is fixed on the fixed bed 40. Sand is installed in the protective box 10. The fixed end 21 of the protective plate 20 is fixed to the moving bed 50 for movement. The free end 22 of the protective plate 20 is inserted into the sand and is always immersed in the sand to prevent the protective plate 20 from leaving the moving bed 50 when the moving bed 50 is moving. Sand creates a gap, causing the fire to burst out; three insulation parts 31 are provided on the left and right and front end of the movable bed 50, and the insulation parts 31 are adjusted to move left and right and up and down by an adjusting mechanism 32 to block the gap between the movable bed 50 and the fixed bed 40. In addition, the insulation part 31 at the front end of the movable bed 50 is provided with a slag discharge port. When the stepping furnace is discharging slag, the movement of the insulation part 31 at the front end of the movable bed 50 is stopped. When the stepping furnace stops discharging slag, the insulation part 31 at the front end of the movable bed 50 can be adjusted to move to block the gap between the movable bed 50 and the fixed bed 40.
