Description

Technical Field

[0001] The utility model belongs to the field of sintering furnaces, and in particular relates to a thermal insulation layer installation and adjustment structure and a sintering furnace system. Background Art

[0002] During the pressureless sintering process, silicon carbide ceramic products are sintered at temperatures exceeding 2200°C. A vertical pressureless sintering furnace, also known as a vertical vacuum sintering furnace, utilizes medium-frequency induction heating to sinter carbide tool tips and various powder compacts in a vacuum or protective atmosphere. Silicon carbide ceramic products are placed vertically in the furnace chamber. After evacuation, the furnace is filled with protective gas, and the pressure and temperature are controlled to complete the sintering process.

[0003] Due to the large furnace chamber, components subject to high temperatures can deform during use due to thermal expansion and contraction. Existing pressureless sintering furnaces experience significant cumulative deformation of the insulation layer after a period of use. These furnaces lack any adjustable positions or have minimal adjustment space. This thermal deformation can affect charging and furnace operation, requiring the furnace to be re-insulated before use. Furthermore, the weight of all products and accessories in current vertical furnaces rests on the bottom of the furnace, requiring the bottom components to withstand temperatures exceeding 2200°C while also possessing high high-temperature strength.

[0015] Furthermore, the adjustment portion further includes a connecting plate, a side wall of the connecting plate is connected to a side of the mounting plate away from the engaging groove, and an adjacent side wall is connected to a side wall of the horizontal plate.

[0016] Furthermore, a limiting structure is provided on the connecting plate for limiting the displacement of the connecting plate toward the inner wall of the furnace body.

For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection, electrical connection, physical connection, or wireless communication connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0041] As attached Figure 1 -Attached Figure 11 As shown, the utility model provides an insulation layer installation and adjustment structure, comprising a plurality of fastening and adjusting members 3 arranged at intervals along the circumferential direction of the inner wall of the furnace body 1. The arrangement of the plurality of fastening and adjusting members 3 is adapted to the cross-sectional shapes of the inner wall of the furnace body 1 and the outer wall of the insulation layer 2. Preferably, the plurality of fastening and adjusting members 3 are arranged at equal intervals to ensure uniform support for the insulation layer 2. For example, when the furnace body 1 and the insulation layer 2 are cylindrical structures, the plurality of fastening and adjusting members 3 are arranged in a ring array around the axial direction of the furnace body 1.

[0042] The fastening adjustment member 3 includes a fixing portion 31 and an adjustment portion 32 that can be adjusted on the fixing portion 31. The fixing portion 31 is used to connect the furnace body 1 and the support adjustment plate 32. The adjustment portion 32 can be moved and adjusted on the fixing portion 31 to adjust the support position of the thermal insulation layer 2. The fixing portion 31 is used to be connected to the inner wall of the furnace body 1. The fixing portion 31 can be integrally formed with the furnace body 1, or it can be fixed to the inner wall of the furnace body 1 by fasteners or welding. A snap-fit ​​groove for mounting the flange 21 on the thermal insulation layer 2 is provided on the adjustment portion 32 toward the middle of the furnace body 1. 3212. Preferably, the size of the snap-fit ​​groove 3212 is larger than the size of the flange 21. At this time, after the flange 21 is installed in the snap-fit ​​groove 3212, the bottom of the flange 21 overlaps the bottom of the snap-fit ​​groove 3212 to complete the fixation, simplifying the setting of the thermal insulation layer 2 on the fastening adjustment member 3. At this time, the fixation of the thermal insulation layer 2 and several fastening adjustment members 3 has a certain degree of freedom, which can adapt to the thermal deformation of the thermal insulation layer 2 caused by thermal expansion and contraction during use, so that the thermal insulation layer 2 can still be effectively supported by the fastening adjustment member 3 under certain deformation conditions, and the thermal insulation layer 2 can be used for a long time.

[0043] The insulation layer installation and adjustment structure provided by the present invention does not directly fix the insulation layer 2 to the furnace body 1, but is indirectly fixed to the furnace body 1 through multiple points of support via a plurality of fastening and adjusting members 3. When the insulation layer 2 is deformed too much and cannot be used, the height of the insulation layer 2 and its concentricity with the furnace body 1 can be adjusted by adjusting the adjustment portion 32 of the corresponding fastening and adjusting member 3, so that the insulation layer 2 can continue to be used. This can greatly reduce the maintenance time and cycle of the insulation layer 2, save a lot of manpower and material resources, improve the efficiency of the sintering furnace, and reduce maintenance costs. At the same time, the insulation layer 2 is supported and fixed to the inner wall of the furnace body 1 by a plurality of fastening and adjusting members 3, which can reduce the number of support points while ensuring the support strength, simplifying the difficulty of adjusting the position of the insulation layer 2.

[0044] In one embodiment, the fixing portion 31 includes a vertical plate 311 fixedly connected to the inner wall of the furnace body 1. Preferably, the vertical plate 311 is welded to the furnace body 1, thereby facilitating installation on an existing furnace body 1 in use. A vertical waist hole 3111 is provided on the vertical plate 311.

[0045] The adjusting portion 32 includes a mounting plate 321 , a snap-fitting groove 3212 provided at one end of the mounting plate 321 , and the end of the mounting plate 321 protrudes from the end surface of the vertical plate 311 , so that after the flange 21 is installed in the snap-fitting groove 3212 , the flange 21 does not contact the vertical plate 311 . The mounting plate 321 is provided with a transverse waist hole I 3211 ;

[0046] The thermal insulation layer installation and adjustment structure also includes fasteners I33 that pass through the vertical waist holes 3111 and the transverse waist holes I3211 to fasten the vertical plate 311 and the mounting plate 321. Fasteners I33 are preferably bolt fasteners to facilitate assembly and disassembly. Washers can be provided on opposite sides of the vertical plate 311 and the mounting plate 321 to enhance the fastening effect of the bolt fasteners. Preferably, at least two sets of vertical waist holes 3111, transverse waist holes I3211, and fasteners I33 are provided longitudinally.

[0047] In this embodiment, the mounting plate 321 can be translated in various directions on the plane of the vertical plate 311, thereby causing the engaging slot 3212 to move toward or away from each other, and upward or downward, along the axial direction of the furnace body 1. During the position adjustment process, the fastener I 33 always cooperates with the vertical waist hole 3111 and the transverse waist hole I 3211. After the adjustment is completed, the fastener I 33 can be tightened to complete the fixation. In this embodiment, the vertical waist hole 3111 and the transverse waist hole I 3211 simplify the position adjustment and fixation of the mounting plate 321, thereby improving the adjustment efficiency. In addition, in this embodiment, the vertical waist hole 3111 is arranged on the vertical plate 311, and the transverse waist hole I 3211 is arranged on the mounting plate 321, which can reduce the impact of the openings on the strength of the vertical plate 311 and the mounting plate 321.

[0048] In one embodiment, the fixing portion 31 further includes a bottom plate 312 connected to the bottom of the vertical plate 311. Preferably, the bottom plate 312 and the vertical plate 311 are integrally formed to improve the connection strength between the two. Preferably, the bottom plate 312 and the vertical plate 311 are perpendicular to each other.

[0049] The adjustment portion 32 further includes a horizontal flat plate 322 connected to the bottom of the mounting plate 321. Preferably, the mounting plate 321 and the horizontal flat plate 322 are integrally formed to improve the connection strength between the two. Preferably, the mounting plate 321 and the horizontal flat plate 322 are perpendicular to each other.

[0050] The present insulation layer installation and adjustment structure also includes a lifting structure for driving the horizontal plate 322 to move closer to or away from the bottom plate 312. By setting up the lifting structure, after the position of the adjustment part 32 is adjusted, the horizontal plate 322 can be pushed up or pulled down, so that the horizontal plate 322 drives the mounting plate 321 to deflect, causing the mounting plate 321 to move away from the vertical plate 311, thereby increasing the friction force of the fastener Ⅰ33 on the mounting plate 321 and the vertical plate 311, and achieving the locking of the fastener Ⅰ33 with the vertical waist hole 3111 and the horizontal waist hole Ⅰ3211, thereby improving its fastening effect, and thereby improving the fixing reliability of the mounting plate 321 to the insulation layer 2.

[0051] In a preferred embodiment, the horizontal plate 322 is provided with a transverse waist hole II 3221 parallel to the transverse waist hole I 3211; the bottom plate 312 is provided with a through hole 3121;

[0052] The lifting structure includes a bolt fastener I34, the screw head I341 of the bolt fastener I34 abuts against the horizontal plate 322, the screw rod I342 passes through the horizontal waist hole II3221 and the through hole 3121 in sequence, and the nut I343 is screwed to the position where the screw rod I342 extends out of the through hole 3121. Preferably, a nut I343 is provided on each side of the through hole 3121 to achieve stable positioning of the bolt fastener I34. In this embodiment, the screw head I341 is used to pull the moving part of the horizontal plate 322. By rotating the nut I343, the screw head can be adjusted. The position of rod I 342 and screw head I 341 adjusts the pulling range of horizontal plate 322, making the entire operation convenient and quick. Moreover, the provision of transverse waist hole II 3221 can adapt to the movement of adjustment portion 32 toward or away from insulation layer 2. The penetration of screw rod I 342 and transverse waist hole II 3221 can adapt to the up and down movement of adjustment portion 32. This allows the lifting structure to always cooperate with horizontal plate 322 and base plate 312 during and after adjustment of adjustment portion 32, greatly simplifying the operation of the lifting structure. In addition, the use of bolt fasteners I 34 as the lifting structure ensures a simple and reliable structure, without the need for drive components, and is suitable for use in high-temperature environments such as sintering furnaces.

[0053] In one embodiment, the adjustment portion 32 further includes a connecting plate 323. One side wall of the connecting plate 323 is connected to the side of the mounting plate 321 facing away from the engaging groove 3212, and the adjacent side wall is connected to the side wall of the horizontal plate 322. The provision of the connecting plate 323 can greatly enhance the structural strength of the mounting plate 321 and the horizontal plate 322, and improve the supporting stability of the mounting plate 321 on the thermal insulation layer 2. Preferably, the connecting plate 323, the horizontal plate 322, and the mounting plate 321 are perpendicular to each other.

[0054] In one embodiment, a limiting structure is provided on the connecting plate 323 for limiting the displacement of the connecting plate 323 toward the inner wall of the furnace body 1, thereby preventing the deformation of the thermal insulation layer 2 from pushing the adjustment part 32 to move toward the inner wall of the furnace body 1. On the one hand, the deformation of the thermal insulation layer 2 can be fixed and limited, and on the other hand, the adjustment part 32 can be prevented from causing compression damage to the inner wall of the furnace body 1.

[0055] In one embodiment, the connecting plate 323 is provided with a matching hole 3231;

[0056] The limiting structure includes a bolt fastener II35. The screw II352 of the bolt fastener II35 passes through the mating hole 3231 and abuts against the inner wall of the furnace body 1. The nut II353 is located at the end of the connecting plate 323 that is away from the engaging groove 3212 (not shown in the figure). At this time, when the connecting plate 323 tends to move toward the inner wall of the furnace body 1, the screw II352 abuts against the inner wall of the furnace body 1, and the nut II353 restricts the connecting plate 323 from further movement along the screw II352, thereby achieving position limiting. Preferably, at least two sets of bolt fasteners II35 and mating holes 3231 are provided longitudinally.

[0057] Alternatively, the limiting structure includes a bolt fastener II35, wherein the screw II352 of the bolt fastener II35 is screwed into the matching hole 3231 and then abuts against the inner wall of the furnace body 1. The nut II353 is located at one end of the connecting plate 323. The nut II353 is used to further enhance the screw connection strength between the screw II352 and the matching hole 3231. In this case, the nut II353 can be located on the side of the connecting plate 323 close to the inner wall of the furnace body 1 or on the side of the connecting plate 323 away from the inner wall of the furnace body 1 (as shown in the illustrated embodiment). In this case, when the connecting plate 323 tends to move toward the inner wall of the furnace body 1, the screw II352 abuts against the inner wall of the furnace body 1 and is screwed into the matching hole 3231, thereby limiting the movement of the connecting plate 323 toward the inner wall of the furnace body 1. Preferably, at least two sets of bolt fasteners II35 and matching holes 3231 are longitudinally arranged.

[0058] In this embodiment, a bolt fastener II35 is used as a position-limiting structure, ensuring a simple and reliable structure without the need for actuating components, making it suitable for use in high-temperature environments such as sintering furnaces. Furthermore, the screw rod II352 of the bolt fastener II35 can be a plain rod or a bolt with a screw head II351. In the case of a bolt with a screw head II351, the screw head II351 and the nut II353 are preferably located on the same side.

[0059] In one specific embodiment, the fixing portion 31 includes a vertical plate 311 and a bottom plate 312, and the adjusting portion 32 includes a mounting plate 321, a horizontal plate 322, and a connecting plate 323. The vertical plate 311 and the mounting plate 321 are coupled together by fasteners I 33, while the horizontal plate 322 and the bottom plate 312 are brought into relative alignment by bolt fasteners I 34. Bolt fasteners II 35 are provided on the connecting plate 323 to restrict movement of the connecting plate 323 toward the inner wall of the furnace body 1. After the adjusting portion 32 is tightened, the weight of the insulation layer 2 exerts a downward force on the mounting plate 321, while bolt fasteners I 34 exert a force that deflects the horizontal plate 322 and the mounting plate 321 away from the vertical plate 311. Bolt fasteners II 35 abut against the inner wall of the furnace body 1, restricting movement of the adjusting portion 32 toward the inner wall of the furnace body 1. These multiple forces act together to further enhance the support stability of the tightening adjusting member 3 on the insulation layer 2.

[0060] In one embodiment, multiple groups of the insulation layer installation and adjustment structure and the flange 21 can be provided along the axial direction of the furnace body 1 to further improve the support stability of the insulation layer 2 by the insulation layer installation and adjustment structure.

[0061] The utility model also provides a method for installing and adjusting the thermal insulation layer of a sintering furnace, using a furnace body 1, a thermal insulation layer 2, and the thermal insulation layer installation and adjustment structure, including a thermal insulation layer installation method and a thermal insulation layer adjustment method. The thermal insulation layer installation method includes the following steps:

[0062] S11, placing the thermal insulation layer 2 in the furnace body 1. During installation, the thermal insulation layer 2 can be hoisted into the furnace body 1 using a hoisting device, and the flange 21 of the thermal insulation layer 2 is engaged with the engaging grooves 3212 of the thermal insulation layer installation and adjustment structure. Before installation, the engaging grooves 3212 of the fastening and adjusting member 3 can be moved toward the inner wall of the furnace body 1 to avoid interference with the thermal insulation layer 2 when the thermal insulation layer 2 is hoisted into the furnace body 1. After the thermal insulation layer 2 is hoisted into the furnace body 1 and its position is adjusted, the adjusting member 2 is adjusted so that the engaging grooves 3212 provide stable support for the flange 21.

[0063] S12, when the concentricity of the insulation layer 2 and the furnace body 1 needs to be adjusted, this can be done during the installation phase, or when the insulation layer 2 is deformed after being used for a certain period of time and needs to be repositioned. In this case, the insulation layer adjustment method is performed;

[0064] The insulation layer adjustment method includes the following steps:

[0065] S21, hoisting the furnace body 1 by a hoisting device, and adjusting the insulation layer 2 to be concentric with the furnace body 1, and adjusting the corresponding fastening and adjusting parts 3 at the same time. Adjusting the fastening and adjusting parts 3 includes:

[0066] S22, loosen fastener I 33, bolt fastener I 34 and bolt fastener II 35, and adjust the adjustment portion 32 to the correct position;

[0067] S23, tighten the fastener I33 to fix the mounting plate 321;

[0068] S24, tighten the nut I 343, so that the horizontal plate 322 moves closer to the bottom plate 312, and the horizontal plate 322 and the mounting plate 321 tend to deform, thereby strengthening the fastening force of the fastener I 33;

[0069] S35 , rotating the nut II 353 or the screw II 352 so that one end of the screw II 352 abuts against the inner wall of the furnace body 1 , thereby limiting the movement of the adjustment portion 32 toward the inner wall of the furnace body 1 ;

[0070] S36, remove the lifting equipment.

[0071] The utility model also provides a sintering furnace system, which includes a furnace body 1, a thermal insulation layer 2 and a thermal insulation layer installation and adjustment structure.

[0072] In one embodiment, refer to the attached Figure 10 and attached Figure 11 The sintering furnace system further includes a furnace bottom support 4, on which the furnace body 1 and the insulation layer 2 are mounted;

[0073] The furnace body bottom support 4 includes bottom pad bricks 41, hard felt 42, graphite bottom plate 43, insulation part and graphite bearing bottom plate 46 arranged in sequence from bottom to top. The insulation part includes several concentrically arranged graphite support tubes 45 connecting the graphite bottom plate 43 and the graphite bearing bottom plate 46, and carbon black insulation material 44 arranged between the several graphite support tubes 45. Among them, the bottom pad bricks 41 are used to provide low-temperature high-strength support and adjust the support height. The hard felt 42 is used to provide medium-temperature high-strength support. The graphite bottom plate 43, graphite support tube 45, and the carbon black insulation material 44 and graphite bearing bottom plate 46 filled in the graphite support tube 45 provide high-temperature heat insulation and high-strength support. In this embodiment, the furnace body bottom support 4 adopts a combination of multiple materials to achieve both heat resistance and heat preservation, and high strength at high temperatures, and ultimately achieve high-temperature load-bearing. The invention solves the problem that the weight of all products and related accessories of the current vertical furnace body is borne by the bottom of the furnace body, but the bottom of the furnace body is difficult to achieve temperature resistance above 2200℃ and also have high high temperature strength.
