Description

Technical Field

[0001] The present invention belongs to the technical field of steel rolling, and particularly relates to a replacement tool for a regenerator of a heating furnace. Background Art

[0002] A regenerative heating furnace is essentially a combination of an effective regenerative heat exchanger and a conventional heating furnace, mainly composed of a heating furnace body, a regenerator chamber, a commutation system, and a fuel, air supply, and smoke exhaust system. The regenerator chamber is the main body for recovering the waste heat of the flue gas in the regenerative heating furnace. It is a chamber-shaped space filled with regenerators and is part of the flow channels for flue gas and air. In a heating furnace, the regenerator chambers are always used in pairs. One furnace can use one pair, several pairs, or even dozens of pairs. In some large domestic heating furnaces, up to more than forty pairs are used. The advantages of regenerative waste heat recovery are that the furnace temperature is more uniform. Due to the uniform furnace temperature distribution, the heating quality is greatly improved, and the product qualification rate is significantly increased. The fuel selection range is wider. It is suitable for various fuels such as light oil, heavy oil, natural gas, and liquefied petroleum gas. Especially for low-calorific-value blast furnace gas and producer gas, it has a good preheating and combustion-supporting effect, expanding the application range of fuels.

[0003] The existing method for replacing the regenerators in a heating furnace is to open the heating furnace, and then take out the regenerators one by one with a clamp and replace them with new regenerators. This process is slow in operation, and the long-term proximity to the heating furnace increases the risk coefficient of the operators. Summary of the Invention

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] Please refer to Figures 1 to 3 , and now the heat storage body replacement tool provided by the present invention will be described. The heat storage body replacement tool for a heating furnace includes a top plate 10, a vertical plate 20, a bottom plate 30 and a pushing and pulling member 40. The vertical plate 20 is arranged at the rear side of the bottom of the top plate 10; the bottom plate 30 is arranged at the bottom of the vertical plate 20, and a detachable positioning member 50 is connected between the vertical plate 20 and the bottom plate 30; the pushing and pulling member 40 is arranged at the rear side of the bottom plate 30. The pushing and pulling member 40 includes a pull rod 42 and a push rod 41. One end of the pull rod 42 is rotatably connected to the bottom plate 30, one end of the push rod 41 is slidably connected to the pull rod 42, and the other end is rotatably connected to the vertical plate 20; in the initial state, the bottom plate 30, the vertical plate 20 and the top plate 10 enclose a cavity for supporting the heat storage body 70, and the bottom plate 30 and the top plate 10 clamp the heat storage body 70 up and down; after the positioning member 50 is removed, the pull rod 42 pulls out the bottom plate 30, and at the same time the push rod 41 pushes the vertical plate 20.

[0041] It should be noted that since the specifications of the heat storage body 70 are fixed, if the height of the heat storage body 70 is h, the distance between the top plate 10 and the bottom plate 30 is n * h, so as to meet the replacement of multiple heat storage bodies 70 at one time.

[0042] Compared with the prior art, when replacing the regenerator 70 with the regenerator replacement tool provided in this embodiment, a plurality of regenerators 70 are stacked on the bottom plate 30 until the top plate 10 and the bottom plate 30 clamp the plurality of regenerators 70. At the same time, the pull rod 42 and the push rod 41 are pushed. At this time, the push rod 41 does not move relative to the pull rod 42, and the bottom plate 30, the top plate 10 and the vertical plate 20 are pushed into the heating furnace. The positioning member 50 is disassembled. At this time, the connection relationship between the bottom plate 30 and the vertical plate 20 is released. The pull rod 42 is pulled. While pulling the pull rod 42, the push rod 41 is pushed, and the bottom plate 30 is pulled out from the bottom of the vertical plate 20. Then the push rod 41 is pulled to pull the vertical plate 20 and the top plate 10 out of the heating furnace. The regenerator replacement tool of the present invention can complete the replacement of a plurality of regenerators 70 at the same time, and the bottom plate 30 is pulled out first, and the vertical plate 20 and the top plate 10 are pulled out later, which is convenient for the accurate placement of the regenerators 70 in the heating furnace and prevents the stacked regenerators 70 from tipping over; this structure is convenient for operation and can realize the replacement of a batch of regenerators 70, improve the replacement efficiency of the regenerators 70, and the time used by the operator when replacing the regenerators 70 is short, avoiding the risk of being scalded by the high-temperature environment.

[0043] In some embodiments, an improved implementation manner of the above-mentioned vertical plate 20 may adopt the structure as Figure 1 shown. Refer to Figure 1 . A positioning plate 21 is provided at the rear side of the bottom of the vertical plate 20. The positioning plate 21 fits on the top surface of the bottom plate 30, and the positioning member 50 is connected to the positioning plate 21 and the bottom plate 30. The positioning plate 21 fits on the top surface of the bottom plate 30, increasing the contact area between the vertical plate 20 and the bottom plate 30, improving the stability of the vertical plate 20, and preventing the regenerator 70 from squeezing the vertical plate 20 and tipping over; the positioning member 50 is arranged on the positioning plate 21, and the operating area of the positioning plate 21 is large, which is convenient for the loading and unloading operation of the positioning member 50.

[0044] In some embodiments, an improved implementation manner of the above-mentioned vertical plate 20 may adopt the structure as Figure 1 shown. Refer to Figure 1 . A reinforcing rib 22 is provided between the positioning plate 21 and the vertical plate 20. Since the height of the vertical plate 20 is relatively high and the regenerator 70 needs to squeeze the vertical plate 20 when being placed, by providing the reinforcing rib 22, the deformation of the vertical plate 20 can be avoided; if the deformation of the vertical plate 20 is relatively large, the whole vertical plate 20 tilts backward, resulting in the overall tilt of the stacked regenerators 70. When the vertical plate 20 is pulled out, the stacked regenerators 70 are likely to tip over. By improving the structural strength of the vertical plate 20 through the reinforcing rib 22, this phenomenon can be avoided.

[0045] In some embodiments, a specific implementation manner of the above-mentioned positioning member 50 may adopt the structure as Figure 1 shown. Refer to Figure 1, the positioning member 50 is a dowel pin. There is a first through hole on the positioning plate 21, and a second through hole corresponding to the first through hole is provided on the bottom plate 30. The dowel pin is inserted and matched with the first through hole and the second through hole respectively. By using a dowel pin as the positioning member 50, when the vertical plate 20 and the bottom plate 30 are connected, the first through hole on the positioning plate 21 and the second through hole on the bottom plate 30 are vertically corresponding. Then, the dowel pin is inserted into the first through hole and the second through hole to complete the connection. When disassembly is required, the bottom plate 30 can be pulled out directly by pulling out the dowel pin. This structure is convenient to use and reduces the labor intensity during the loading and unloading process of the positioning member 50.

[0046] In some embodiments, an improved implementation of the above-mentioned top plate 10 can adopt the structure as Figure 1 shown. Refer to Figure 1 , the top plate 10 is connected to the vertical plate 20 through a rotating shaft 11. The axial direction of the rotating shaft 11 is parallel to the plate surface of the top plate 10 and the plate surface of the vertical plate 20 respectively. Torsion springs 12 are provided at both ends of the rotating shaft 11, and the torsion springs 12 are configured with a pre-tightening force to press the front side of the top plate 10 downward. The torsion spring 12 is a torsion spring. The two shaft ends of the torsion spring extend out of the support strip respectively. When the top plate 10 rotates around the center of the torsion spring 12, the torsion spring 12 pulls the top plate 10 back to the initial position. In the initial state, the front side of the top plate 10 is inclined downward. As the regenerators 70 are gradually stacked, the topmost regenerator 70 presses the front side of the top plate 10, causing the top plate 10 to rotate to a horizontal state. At this time, due to the pre-tightening force on the torsion spring 12, the top plate 10 and the bottom plate 30 cooperate to clamp a plurality of regenerators 70, improving the stability of the fixation of the regenerators 70 and preventing the regenerators 70 from scattering due to inertia during the pushing process.

[0047] In some embodiments, an improved implementation of the above-mentioned heating furnace regenerator replacement tool can adopt the structure as Figures 2 to 3 shown. Refer to Figures 2 to 3 , the heating furnace regenerator replacement tool further includes two side plates 60, and the two side plates 60 are respectively arranged on the left and right sides of the vertical plate 20; the top of the side plate 60 is connected to the top plate 10, the rear side of the side plate 60 is connected to the vertical plate 20, and the bottom of the side plate 60 is slidably connected to the bottom plate 30. By providing the side plates 60, not only the regenerators 70 are clamped at the top and bottom, but also the regenerators 70 are positioned on the left and right sides by the two side plates 60 to prevent the regenerators 70 from sliding out from the left and right sides.

[0048] In some embodiments, an improved implementation of the above-mentioned side plate 60 can adopt the structure as Figures 2 to 3 shown. Refer to Figures 2 to 3, a plurality of first card slots 13 are formed by recessing the bottom surface of the top plate 10 at intervals in the left - right direction, and a first card block 61 that cooperates with the first card slots 13 is protrudingly provided at the top of the side plate 60; a plurality of second card slots 24 are formed by recessing the front side surface of the vertical plate 20 at intervals in the left - right direction, and a second card block 62 that cooperates with the second card slots 24 is protrudingly provided at the rear side of the side plate 60; a chute 31 extending in the front - rear direction is formed by recessing the top surface of the bottom plate 30, and a plurality of chutes 31 are provided at intervals in the left - right direction, and a slider 63 that slidably cooperates with the chute 31 is protrudingly provided at the bottom of the side plate 60. Through the clamping connection of the first card slots 13, the second card slots 24, and the chute 31, the fixation of the side plate 60 can be realized, the stability of the fixation of the side plate 60 can be improved, and the mutual assembly between the top plate 10, the side plate 60, the vertical plate 20, and the bottom plate 30 is facilitated; a plurality of first card slots 13 and second card slots 24 are both provided at intervals in the left - right direction, which can adjust the side plate 60 left - right, and thus adapt to the installation of heat storage bodies 70 with different widths, and the adaptability is higher.

[0049] In some embodiments, an improved implementation of the above - mentioned push - pull member 40 can adopt a structure as Figure 1 shown. Refer to Figure 1 , a sliding sleeve 43 is slidably fitted on the pull rod 42, and the end of the push rod 41 is rotatably connected to the sliding sleeve 43; a limiting step 44 is provided on the pull rod 42 at the front side of the sliding sleeve 43. When the push rod 41 pushes the vertical plate 20 a preset distance, the sliding sleeve 43 abuts against the limiting step 44. Pull out the bottom plate 30 by pulling the pull rod 42, and at the same time push the push rod 41. The push rod 41 drives the sliding sleeve 43 to move. When the bottom plate 30 is just pulled out, the sliding sleeve 43 abuts against the limiting step 44. At this time, the push rod 41 cannot continue to push. When continuing to pull the pull rod 42, the pull rod 42 can drive the limiting step 44 to pull the push rod 41, and the push rod 41 pulls out the vertical plate 20 and the top plate 10. By setting the limiting step 44 and the sliding sleeve 43, it is convenient to limit the pushing distance of the push rod 41. Thus, after the bottom plate 30 is pulled out, the vertical plate 20 and the top plate 10 can be pulled out together with the push rod 41 by the pull rod 42, which is convenient for operation.

[0050] In some embodiments, an improved implementation of the above - mentioned push - pull member 40 can adopt a structure as Figure 1 shown. Refer to Figure 1, a hand ring 45 is provided at the free end of the pull rod 42. One end of the sliding sleeve 43 facing the hand ring 45 is connected with an extension rod 46. The extension rod 46 penetrates through the hand ring 45. A clamping ball 47 is provided at the free end of the extension rod 46. The diameter of the clamping ball 47 is larger than that of the hand ring 45. The hand ring 45 on the pull rod 42 facilitates manually pulling the hand ring 45 to further pull the pull rod 42, and a pull rope can also be tied to the pull rod 42 for pulling; since there is a certain distance between the sliding sleeve 43 and the free end of the pull rod 42 when the sliding sleeve 43 slides to the limit step 44, it is inconvenient to directly pull the push rod 41 by pulling the sliding sleeve 43. By providing the extension rod 46, the push rod 41 can be directly pulled out by pulling the extension rod 46, and then the vertical plate 20 and the top plate 10 can be pulled out. The diameter of the clamping ball 47 being larger than that of the hand ring 45 can prevent the extension rod 46 from detaching from the hand ring 45, facilitating the simultaneous operation of the pull rod 42 and the push rod 41 at the same position.

[0051] In some embodiments, an improved implementation manner of the above-mentioned vertical plate 20 can adopt the structure as Figure 1 shown. Refer to Figure 1 . A reinforcing plate 23 is provided in the middle at the rear side of the vertical plate 20. The plate surface of the reinforcing plate 23 is perpendicular to the plate surface of the vertical plate 20. The width of the reinforcing plate 23 gradually decreases from front to back. The push rod 41 is rotatably connected to the reinforcing plate 23. If the push rod 41 is directly rotatably connected to the rear side of the vertical plate 20, pushing the push rod 41 may cause the vertical plate 20 to bulge and deform due to stress concentration. By providing the reinforcing plate 23, the thrust can act on the vertical plate 20 evenly, and it is more labor-saving during the pushing process.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
