Description

Technical Field

[0001] This invention relates to the field of industrial furnace technology, and in particular to a high-insulation furnace lining structure for industrial furnaces. Background Technology

[0002] Industrial furnaces are thermal equipment that use the heat from fuel combustion or electrical energy conversion to heat materials or workpieces. They mainly consist of a furnace body, a heating system, and a flue gas system. According to the heating method, they are divided into flame furnaces and electric furnaces, and according to the thermal system, they are divided into intermittent furnaces and continuous furnaces.

[0003] During the operation of high-temperature industrial furnaces such as industrial heat treatment furnaces, heating furnaces, and smelting furnaces, the internal temperature of the furnace chamber can generally reach hundreds to thousands of degrees Celsius. As a core component that isolates the high temperature of the furnace chamber and reduces heat loss, the furnace lining's heat insulation capacity and assembly structure stability directly determine the energy consumption and service life of the industrial furnace. Currently, traditional industrial furnace linings in the industry mostly adopt monolithic casting of a single refractory castable or splicing of refractory plates.

[0004] However, during long-term high-temperature operation, the joints of traditional spliced ​​furnace lining plates lack a dedicated sealing and compensation structure. As the refractory plates expand when heated and contract when cooled, the gaps continue to widen. High-temperature hot air and heat radiation inside the furnace diffuse outward through these gaps, forming numerous convection heat dissipation channels. This results in a significant temperature rise on the outer wall of the furnace and severe heat loss. While integrally cast furnace linings have fewer gaps, localized cracking or damage to the refractory layer later cannot be replaced individually; the entire lining must be dismantled and rebuilt, leading to high maintenance costs and long downtime. Furthermore, the existing modular refractory lining plate assembly structure is simple, relying only on a single clip or bolt at a single point. Under high-temperature cyclic thermal shock, the fasteners are prone to loosening and falling off, causing the lining plates to shift or fall off, further widening the heat dissipation gaps. Moreover, there is no pre-positioning auxiliary structure during lining plate assembly, requiring repeated manual correction of the plate positions during construction. This results in low assembly efficiency and high labor costs for multi-layer annular furnace linings. Furthermore, the existing furnace lining disassembly and assembly structure lacks a synchronous adjustment and locking mechanism, making it impossible to simultaneously tighten the entire ring of lining plates, which can easily lead to problems such as localized lining plate compression and localized lining plate loosening. When disassembling damaged lining plates, the plates become stuck together, and there is no auxiliary ejection structure, making it difficult for operators to remove the damaged insulation plates. This makes disassembly and assembly operations difficult and replacement inefficient. Summary of the Invention

[0005] In order to solve the technical problems of poor heat insulation and sealing, high heat loss, inconvenient assembly and maintenance, and insufficient structural stability under high temperature conditions in existing industrial furnace linings, this invention provides a high heat insulation furnace lining structure for industrial furnaces.

[0006] The technical solutions provided by the embodiments of the present invention are as follows:

[0007] This invention provides a high-insulation furnace lining structure for an industrial furnace, comprising: a furnace lining mechanism, wherein the furnace lining mechanism includes furnace lining components, adjusting components, and assembly components;

[0008] The furnace lining component includes a heat-insulating base lining. Multiple sliding sleeves are arranged in a circumferentially equidistant array on the top of the heat-insulating base lining. Each sliding sleeve has three pairs of slots on its outer wall. A filling ring is snapped into the outer wall of each sliding sleeve. Support rods are slidably connected inside each sliding sleeve. These support rods are fixedly connected to the heat-insulating base lining by bolts. A connecting ring is fixedly connected to the top of each support rod. Three heat-insulating arc plates are provided between every two adjacent support rods. Mounting slots are provided on both sides of each heat-insulating arc plate. Three reinforcing members are fixedly connected to one side of each support rod. A triangular cone rod is fixedly installed on the side of each reinforcing member away from the corresponding support rod. The triangular cone rod has a tapered structure that is narrower at the top and wider at the bottom, used to seal the gaps between adjacent heat-insulating arc plates.

[0009] The furnace lining components can quickly lay and position the heat insulation arc plates on the inner wall of the industrial furnace, achieving rapid laying and assembly of the heat insulation arc plates and improving the assembly efficiency and speed of the heat insulation arc plates for the workers.

[0010] Furthermore, rotating blocks are fixedly connected to both sides of the heat insulation arc plate. A limiting groove is opened inside the rotating block, and the sliding sleeve is inserted into the limiting groove to limit the rotation of the rotating block. The top of the reinforcing member is rounded, and inclined slots are opened on both sides of the top of the reinforcing member. The inclined slots are used to assist in the positioning and assembly of the heat insulation arc plate.

[0011] Furthermore, the adjusting component includes a gear ring, which is rotatably connected inside the connecting ring. The outer wall of the gear ring is meshed with multiple gears, the number of which is the same as the number of sliding sleeves. The gears pass through the connecting ring and are rotatably connected to the top of the sliding sleeves. The top of each of the multiple gears is fixedly connected with a threaded rod, and the outer wall of each of the multiple threaded rods is threadedly connected with a threaded sleeve. The multiple threaded sleeves are fixedly installed inside the connecting ring.

[0012] Furthermore, a connecting block is fixedly connected to the outer wall of the toothed ring, and two arc-shaped rotating rods are rotatably connected inside the connecting block. The two arc-shaped rotating rods are symmetrically arranged inside the connecting block and are used to control the assembly and disassembly of the heat insulation arc plate. Both arc-shaped rotating rods are inserted into the inside of the connecting ring, and each arc-shaped rotating rod has a pin groove inside. A first triangular push block is fixedly installed on the top of the inner wall of the pin groove.

[0013] Furthermore, a pin is inserted into the inside of the pin slot, the pin is inserted into the inside of the connecting ring, and a top block is fixedly connected to the outer wall of the pin. The top block is set at the bottom of the corresponding pin slot and is used to drive the arc-shaped rotating rod to disengage from the inside of the connecting ring through the pin slot.

[0014] Furthermore, the assembly component includes three connecting pieces fixedly installed on one side of the sliding sleeve. A mountain-shaped locking member is fixedly connected to the side of the connecting piece away from the corresponding sliding sleeve. A reset block is fixedly installed inside the mountain-shaped locking member, and a clearance groove is opened inside the mountain-shaped locking member.

[0015] Furthermore, two locking plates are provided between the connecting piece and the mountain-shaped locking member. The two locking plates are slidably connected inside the support rod. The two locking plates are respectively inserted into the mounting grooves of adjacent heat insulation arc plates. A bent locking strip is fixedly connected to the side of the locking plate away from the connecting piece. The bent locking strip abuts against the inner wall of the mountain-shaped locking member, and the locking plate abuts against one side of the bent locking strip.

[0016] Furthermore, a triangular block is fixedly connected to the bottom outer wall of the mountain-shaped locking member on the side away from the connecting piece. A rotating groove is opened inside the reinforcing member and the triangular cone rod. The triangular block is inserted into the rotating groove. A rotating plate is rotatably connected inside the rotating groove. A second triangular push block is fixedly connected to the side of the rotating plate near the triangular block.

[0017] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0018] 1. The heat insulation base is used as the bottom heat insulation base, and multiple heat insulation arc plates are used to form a continuous refractory heat insulation layer; the triangular cone rod is wedge-tightly sealed to block the joint gap of the arc plate; the filling ring seals the gap at the top of each layer of arc plate in layers, which improves the sealing effect, greatly reduces the heat loss of the industrial furnace body, improves the heat utilization rate of the industrial furnace, saves production energy consumption, and the heat insulation arc plate is narrow at the bottom and wide at the top, and the triangular cone rod is narrow at the top and wide at the bottom. When thermal expansion and contraction occur, the two fit together to compensate for each other, and no new gaps will be generated due to temperature changes, thus maintaining the sealing and heat insulation effect continuously;

[0019] 2. The heat insulation arc plate is initially positioned by hooking the side rotating block onto the inclined slot of the reinforcing member. It does not require repeated manual correction and can be laid quickly in layers and rings, which greatly shortens the furnace lining construction period and reduces labor assembly costs.

[0020] 3. The gear ring linkage with multiple sets of gears and threaded rods synchronously drives the lifting and lowering of all sliding sleeves, and the entire heat insulation arc plate is synchronously pressed, so there is no problem of local loosening or local overtightness. The locking plate is inserted into the heat insulation arc plate mounting groove and the sliding sleeve is inserted into the limit groove to form a double mechanical fixation, so the liner is not easy to shift or loosen under high temperature vibration and thermal cycling.

[0021] 4. Reverse rotation of the gear ring can simultaneously release all locking structures, causing the mountain-shaped locking parts to reset and the locking plates to retract and unlock. At the same time, the top block pushes the rotating plate to lift the bottom of the heat insulation arc plate, causing the heat insulation arc plate to automatically disengage from the triangular cone rod gap. This makes it easy to grab and disassemble without removing the entire furnace lining, resulting in fast maintenance, short downtime, and low maintenance costs. Attached Figure Description

[0035] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0036] like Figures 1 to 8 As shown, an embodiment of the present invention provides a high-insulation furnace lining structure for an industrial furnace, comprising: a furnace lining mechanism, the furnace lining mechanism including furnace lining components, adjusting components, and assembly components;

[0037] The furnace lining component includes an insulating base lining 101. Multiple sliding sleeves 102 are arranged in a circumferentially equidistant array on the top of the insulating base lining 101. Each sliding sleeve 102 has three pairs of slots 114 on its outer wall. A filling ring 103 is snapped into the outer wall of each sliding sleeve 102. Support rods 104 are slidably connected inside each sliding sleeve 102. The support rods 104 are fixedly connected to the insulating base lining 101 by bolts. A connecting ring 105 is fixedly connected to the top of each support rod 104. Three insulating arc plates 106 are provided between every two adjacent support rods 104. Mounting grooves 107 are provided on both sides of each insulating arc plate 106. Three reinforcing members 108 are fixedly connected to one side of each support rod 104. A triangular cone rod 109 is fixedly installed on the side of each reinforcing member 108 away from the corresponding support rod 104. The triangular cone rod 109 has a tapered structure that is narrower at the top and wider at the bottom, used to seal the gaps between adjacent insulating arc plates 106.

[0038] It should be noted that the present invention can initially lay and position the heat insulation arc plate 106 on the inner wall of the industrial furnace through the furnace lining component, thereby achieving the effect of rapid laying and assembly of the heat insulation arc plate 106.

[0039] It should be noted that the heat insulation arc plate 106 of the present invention has an arc-shaped structure that is narrow at the bottom and wide at the top, which corresponds to the cone-shaped structure that is narrow at the top and wide at the bottom of the triangular cone rod 109. This allows the workers to hang the heat insulation arc plate 106 inside the inclined slot 111 by using the rotating block 112. When laying the heat insulation arc plate 106, adjacent heat insulation arc plates 106 will not jam against each other when rotating.

[0040] Furthermore, rotating blocks 112 are fixedly connected to both sides of the heat insulation arc plate 106. A limiting groove 113 is opened inside the rotating block 112. The sliding sleeve 102 is inserted into the limiting groove 113 to limit the rotation of the rotating block 112. The top of the reinforcing member 108 is provided with a rounded corner 110. Both sides of the top of the reinforcing member 108 are provided with inclined slots 111. The inclined slots 111 are used to assist in the positioning and assembly of the heat insulation arc plate 106.

[0041] In one possible implementation, the adjusting component includes a gear ring 201 rotatably connected to the inside of a connecting ring 105. Multiple gears 202 mesh with the outer wall of the gear ring 201, the number of gears 202 being the same as the number of sliding sleeves 102. Each gear 202 passes through the connecting ring 105 and is rotatably connected to the top of a sliding sleeve 102. Threaded rods 203 are fixedly connected to the top of each of the multiple gears 202. Threaded sleeves 204 are threadedly connected to the outer walls of each of the multiple threaded rods 203. Multiple threaded sleeves 204 are fixedly installed inside the connecting ring 105. A connecting block 210 is fixedly connected to the outer wall of the gear ring 201, and two arc-shaped rotating rods 20 are rotatably connected inside the connecting block 210. 7. Two arc-shaped rotating rods 207 are symmetrically arranged inside the connecting block 210 to control the assembly and disassembly of the heat insulation arc plate 106. Both arc-shaped rotating rods 207 are inserted into the connecting ring 105. Both arc-shaped rotating rods 207 have pin slots 208 inside. A first triangular push block 209 is fixedly installed on the top of the inner wall of the pin slot 208. A pin 205 is inserted into the inside of the pin slot 208. The pin 205 is inserted into the inside of the connecting ring 105. A top block 206 is fixedly connected to the outer wall of the pin 205. The top block 206 is set at the bottom of the corresponding pin slot 208 and is used to drive the arc-shaped rotating rod 207 to disengage from the inside of the connecting ring 105 through the pin slot 208.

[0042] It should be noted that the present invention can quickly lock and fix the initially laid heat insulation arc plate 106 by adjusting the component to drive the assembly component, and when it is necessary to replace the heat insulation arc plate 106 that has been damaged by long-term operation, the locking and fixing of the heat insulation arc plate 106 can be quickly stopped so that the damaged heat insulation arc plate 106 can be replaced and re-locked and fixed.

[0043] In one possible implementation, the assembly component includes three connecting pieces 301 fixedly mounted on one side of the sliding sleeve 102. A U-shaped locking member 302 is fixedly connected to the side of each connecting piece 301 away from the corresponding sliding sleeve 102. A reset block 303 is fixedly mounted inside the U-shaped locking member 302. A clearance groove 306 is formed inside the U-shaped locking member 302. Two locking pieces 304 are disposed between the connecting pieces 301 and the U-shaped locking member 302. The two locking pieces 304 are slidably connected inside the support rod 104. The two locking pieces 304 are respectively inserted into the mounting grooves 107 of adjacent heat insulation arc plates 106 for locking. A bent locking strip 305 is fixedly connected to the side of plate 304 away from connecting plate 301. The bent locking strip 305 abuts against the inner wall of the mountain-shaped locking member 302. The locking plate 304 abuts against one side of the bent locking strip 305. A triangular block 307 is fixedly connected to the bottom outer wall of the mountain-shaped locking member 302 away from connecting plate 301. A rotating groove 308 is opened inside the reinforcing member 108 and the triangular cone rod 109. The triangular block 307 is inserted into the inside of the rotating groove 308. A rotating plate 309 is rotatably connected inside the rotating groove 308. A second triangular push block 310 is fixedly connected to the side of the rotating plate 309 near the triangular block 307.

[0044] It should be noted that the present invention can lock and fix the heat insulation arc plate 106 laid on the furnace lining component through the assembly component, and can quickly stop locking and fixing the heat insulation arc plate 106 when removing and replacing it. It can also lift up the heat insulation arc plate 106 that has lost its fixation, so that the assembled heat insulation arc plates 106 are staggered from each other, making it convenient for workers to remove the heat insulation arc plate 106 from the furnace lining component.

[0045] Working principle: When installing the furnace lining of the industrial furnace, firstly, the heat insulation base lining 101 is installed at the bottom of the inner wall of the industrial furnace. The filling ring 103 is fitted onto the outer wall of the sliding sleeve 102 of the support rod 104 and pushed up the outer wall of the sliding sleeve 102 to the bottom of the connecting ring 105. The support rod 104 is then placed inside the industrial furnace and fixedly connected to the heat insulation base lining 101 with bolts. The connecting ring 105 is then fixed to the industrial furnace with bolts. Finally, the heat insulation arc plate 106 is inserted into the support rod 104 from bottom to top, circle by circle, through the rotating block 112. Inside the inclined slot 111 of the upper reinforcing member 108, when a ring of heat insulation arc plate 106 is hung on the reinforcing member 108 of the support rod 104 through the rotating block 112 and the inclined slot 111, a filling ring 103 is moved down to the top of the heat insulation arc plate 106 and then stopped. The gap generated by the rotation of the top of the heat insulation arc plate 106 into a semi-circle is sealed to avoid affecting the heat insulation and protection effect on the industrial furnace. Then the above steps are repeated until all the heat insulation arc plates 106 are initially laid. At this time, the installation of the furnace lining is ready.

[0046] Furthermore, after the preparation for the furnace lining installation is completed, the worker can pull the pin 205 upwards along the inside of the connecting ring 105. The pin 205 drives the top block 206 to slide upwards along the inside of the pin groove 208, causing the top block 206 to press against the first triangular push block 209. This causes the first triangular push block 209 to push the arc-shaped rotating rod 207 to rotate around the rotating connection point with the connecting block 210, causing the end of the arc-shaped rotating rod 207 away from the connecting block 210 to disengage from the inside of the connecting ring 105. At this point, the worker can use the part of the arc-shaped rotating rod 207 that has disengaged from the inside of the connecting ring 105 to disengage. The arc-shaped rotating rod 207 is rotated out from inside the connecting ring 105 and driven to rotate the connecting block 210. The connecting block 210 drives the gear ring 201 to rotate along the inside of the connecting ring 105, which in turn drives the gear 202 to rotate. The gear 202 drives the threaded rod 203 to unscrew from inside the threaded sleeve 204 and descend. The descent of the threaded rod 203 pushes the gear 202 to slide down along the outer wall of the gear ring 201. The gear 202 then pushes the sliding sleeve 102 to descend relative to the support rod 104. The sliding sleeve 102, through the connecting piece 301, drives the mountain-shaped locking piece 302 relative to the support rod 104. 4. The internal locking pieces 304 slide relative to each other, causing the clearance groove 306 inside the mountain-shaped locking member 302 to gradually offset from the protruding part of the bent locking strip 305 on the locking piece 304. The mountain-shaped locking member 302 pushes the locking piece 304 outward by squeezing the inclined surface of the protruding bent locking strip 305, so that the two locking pieces 304 move away from each other and are inserted into the mounting groove 107 of the adjacent heat insulation arc plate 106, locking and fixing the heat insulation arc plate 106. This allows the slot 114 on the sliding sleeve 102 to descend and offset from the limiting groove 113 on the rotating block 112, allowing the sliding sleeve 102 to insert into the limiting groove 113. The slot 113 limits and fixes the rotation of the rotating block 112, and performs secondary locking and fixing of the heat insulation arc plate 106, thereby improving the locking and fixing strength of the heat insulation arc plate 106 assembly and preventing the heat insulation arc plate 106 from loosening during long-term operation and the appearance of gaps between multiple heat insulation arc plates 106, which would affect the heat insulation protection of the industrial furnace. Finally, the operator rotates the arc-shaped rotating rod 207 into the inside of the connecting ring 105 and resets the connecting ring 105 to limit the arc-shaped rotating rod 207, thereby preventing relative displacement between the toothed ring 201 and the connecting ring 105, which could lead to loosening of the assembly and fixing of the heat insulation arc plate 106.

[0047] It should be noted that before the clearance groove 306 on the mountain-shaped locking member 302 pushes the bent locking strip 305 on the locking piece 304, the mountain-shaped locking member 302 will drive the triangular block 307 to stop pressing and pushing the second triangular push block 310 on the rotating plate 309, so that the heat insulation arc plate 106 can rotate vertically downward with the rotating block 112 as the rotation center, so that the mounting groove 107 on the heat insulation arc plate 106 can be basically aligned with the corresponding locking piece 304, so that the locking piece 304 can be guided by the mounting groove 107 and inserted into the mounting groove 107 when it is relatively pressed by the mountain-shaped locking member 302;

[0048] Furthermore, when some of the heat insulation arc plates 106 are damaged during long-term use and need to be replaced, the operator can remove the arc-shaped rotating rod 207 from inside the connecting ring 105 and rotate it in the opposite direction. This causes the sliding sleeve 102 to rise relative to the support rod 104, realigning the slot 114 of the sliding sleeve 102 with the limiting slot 113 on the rotating block 112, stopping the rotational limitation on the rotating block 112, and allowing the sliding sleeve 102 to pass through... The connecting piece 301 drives the mountain-shaped locking member 302 to reset. During the reset process, the mountain-shaped locking member 302 gradually shifts away from the protrusion on the bent locking strip 305, aligning the protrusion on the bent locking strip 305 with the relief groove 306. At this time, the reset block 303 on the mountain-shaped locking member 302 pushes the protruding part of the bent locking strip 305 into the interior of the relief groove 306, allowing the bent locking strip 305 to pull the locking piece 304 from the heat insulation arc plate. The heat insulation arc plate 106 disengages from the mounting groove 107, stopping its restriction. Then, as the mountain-shaped locking member 302 continues to rise, the triangular block 307 on the mountain-shaped locking member 302 will begin to contact the second triangular push block 310 on the rotating plate 309, pushing the second triangular push block 310 to rotate inside the rotating groove 308. This allows the second triangular push block 310 and the rotating plate 309 to rotate the part of the heat insulation arc plate 106 away from the rotating block 112, causing the bottom of the heat insulation arc plate 106 to disengage from the triangular cone rods 109 of the adjacent support rods 104. This makes it easier for workers to lift the heat insulation arc plate 106 by its bottom sides and remove it, preventing the heat insulation arc plate 106 from falling after losing its fixation and causing damage to the industrial furnace and the undamaged furnace lining structure, or from continuing to be stuck between the triangular cone rods 109 of the adjacent support rods 104, resulting in workers having no gripping points to remove the heat insulation arc plate 106.

[0049] This invention simultaneously constructs a high-temperature resistant heat insulation seal during the assembly of the entire furnace lining. The heat insulation base 101 serves as the bottom high-temperature resistant heat insulation base to isolate heat dissipation from the bottom. The gaps between every two layers of heat insulation arc plates 106 are sealed by the filling ring 103 on the outside of the sliding sleeve 102. The gaps between adjacent heat insulation arc plates 106 are wedged and filled by a triangular cone rod 109 to eliminate heat dissipation gaps and reduce the heat leakage efficiency inside the industrial furnace. Furthermore, the heat insulation base 101, heat insulation arc plates 106, filling ring 103, and triangular cone rod 109 are all made of high-refractory fiber composite material, possessing high-temperature resistance and low thermal conductivity. Metal support components such as support rods 104 and reinforcing members 108 are completely covered by the heat insulation components, avoiding direct contact with the high temperature inside the industrial furnace. After the adjustment components are locked, it can ensure that each heat insulation component fits tightly. Under high-temperature conditions, there will be no heat leakage gaps due to thermal expansion. Even after long-term use, it still maintains a stable high heat insulation effect, reducing heat loss in the industrial furnace and improving the heat utilization rate inside the industrial furnace.
