Description

Technical Field

[0001] The present application relates to the technical field of sintering, and particularly relates to a temperature zone isolation device for a sintering device and a sintering device. Background Art

[0002] A sintering device is a device utilized in the sintering process, such as a sintering furnace. A sintering furnace is a continuous sintering industrial kiln furnace that conveys materials through roller rods. According to different sintering process requirements, there are multiple temperature zone divisions in the sintering device. To prevent temperature leakage between different temperature zones, a dedicated temperature zone isolation structure is generally provided between different temperature zones. For example, a fireproof partition, i.e., a partition beam, is provided at the top of the kiln furnace of the sintering furnace. The traditional temperature zone isolation structure is a fixed structure, such as a fixed partition beam. The fixed partition beam usually has a structural design of bottom support and top partition plate, and is replaced by being pulled out from the side during maintenance. Currently, the temperature zone isolation structure of the sintering furnace mostly focuses on improving the structural strength and heat insulation effect. For example, CN210533003U discloses a temperature zone isolation device for a roller hearth furnace, which is dedicated to significantly improving the overall strength of the partition beam to meet the structural requirements of a wide furnace hearth and ensure the temperature and atmosphere control effects between temperature zones.

[0003] With the in-depth development of kiln furnace technology and the increase in material production capacity requirements, to meet the sintering requirements of higher-layer and multi-row crucibles, the furnace type of the sintering furnace has continuously developed from a four-row and two-layer sintering furnace to a four-row and three-layer sintering furnace and a four-row and four-layer sintering furnace. To meet the high production capacity requirements, the four-row and four-layer sintering furnace has also entered the market for application. Currently, considering issues such as heat insulation effect, the high-production-capacity furnace type of the sintering furnace cannot be directly converted for use with the low-production-capacity furnace type. All the publicly available sintering furnace types are fixed furnace types, that is, they can only match the sintering of a preset number of layers and rows of crucibles. The problem of adjustable furnace type of the sintering device urgently needs to be solved. Summary of the Invention

[0043] To describe in detail the technical content, achieved objectives and effects of the present application, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0044] Please refer to Figure 1, the technical solution provided by this application: a temperature zone isolation structure of a sintering device, including a support base member 1 extending along a first direction and a heat insulation member 2 extending along a second direction. The heat insulation member 2 is used to seal a preset heat insulation area, and further includes at least two adjusting members 3 and a first support member 4 extending along the second direction. At least two positioning portions 11 are respectively arranged at intervals along the first direction on the support base member 1. At least two of the adjusting members 3 are respectively arranged in one-to-one correspondence with at least two of the positioning portions 11. The adjusting member 3 is detachably arranged on the support base member 1 through the positioning portion 11. The first support member 4 supports on the adjusting member 3 among at least two adjusting members 3 that is close to the top of the support base member 1. The heat insulation member 2 supports on the first support member 4. An open adjusting space is formed by enclosing between the first support member 4 and the bottom of the support base member 1.

[0045] As can be seen from the above description, the beneficial effects of this application are as follows:

[0046] When designing the temperature zone isolation structure of the above sintering device, during installation, the temperature zone isolation structure is fixed at the top of the furnace cavity and located at the junction of two adjacent temperature zones. The first direction is unified with the height direction of the furnace body, and the second direction is unified with the width direction of the furnace body. The heat insulation member extends along the second direction and is located at the junction. The heat insulation member is used to seal a preset heat insulation area, that is, to insulate the furnace chamber top space between two adjacent temperature zones to prevent temperature leakage. On this basis, at least one positioning portion and at least one adjusting member corresponding to it are arranged in the first direction. The adjusting member is detachably arranged on the positioning portion. The first support member supports on the adjusting member closest to the top. The heat insulation member supports on the first support member. An open adjusting space is formed by enclosing between the first support member and the bottom of the support base member. The adjusting space and the furnace cavity form a height space for the sagger to pass through. With such a structural design, by disassembling the adjusting member, the height of the adjusting space formed by enclosing between the first support member arranged on the adjusting member and the bottom of the support base member can be adjusted, and then the height space formed by the adjusting space and the furnace cavity for the sagger to pass through can be adjusted.

[0047] For example, when the production capacity demand is high, four rows and four layers of saggers need to pass through the firing direction of the furnace cavity. At this time, the first support member is supported on the adjusting member closest to the top (the number of adjusting members and positioning parts can be designed according to actual needs, such as two or three), and the heat insulation member is supported on the first support member. The heat insulation member insulates the furnace cavity above the first support member. A relatively large open adjusting space is formed between the bottom of the first support member and the support base member. The adjusting space communicates with the furnace cavity to form a relatively high furnace cavity space. At this time, a larger number of layers of saggers can pass through, such as four rows and four layers of saggers; when the production capacity demand is average or low, for example, only four rows and three layers or four rows and two layers of saggers need to pass through. At this time, the original adjusting member closest to the top is removed from the corresponding positioning part, and the adjusting member below the original adjusting member closest to the top becomes the new adjusting member closest to the top. Then the first support member is supported on the new adjusting member closest to the top, and the heat insulation member is supported on the first support member. The heat insulation member insulates the furnace cavity above the first support member. The adjusting space formed between the bottom of the first support member and the support base member is smaller than before. The height space for the saggers to pass through formed after the adjusting space communicates with the furnace cavity is reduced. At this time, a smaller number of layers of saggers can pass through, such as four rows and three layers or four rows and two layers of saggers; thus, the structure of the temperature zone isolation device can be adjusted, and further the furnace type of the sintering device can be adjusted.

[0048] As a specific structural example, it further includes a second support member 5 extending along the second direction. The second support member 5 is supported on the first support member 4, and the heat insulation member 2 is limited to the side of the second support member 5 away from the first support member 4.

[0049] As can be seen from the above description, on the one hand, the second support member and the first support member together can strengthen the overall structure of the temperature zone isolation structure and improve the strength and stability of the overall structure. On the other hand, the second support member can be designed to limit the heat insulation member, which also helps to improve the support stability of the heat insulation member.

[0050] As a specific structural example, the second support member 5 is a groove structure. The notch of the groove structure of the second support member 5 faces the heat insulation member 2, and the heat insulation member 2 is limited to the groove structure.

[0051] As can be seen from the above description, for the second support member with a groove structure, for example, an existing channel steel structure can be used, which can better limit the heat insulation member.

[0052] As a specific structural example, the first support member 4 is a hollow strip structure.

[0053] As can be seen from the above description, in the optional structural example, the first support member can be a hollow strip structure. For example, a hollow square or a hollow special-shaped structural member, etc.

[0054] As a specific structural example, the heat insulation member 2 includes a first heat insulation part 21 and a second heat insulation part 22 that are hermetically connected, and the first heat insulation part 21 and the second heat insulation part 22 form an auxiliary sealing structure 24 for hermetic connection on adjacent sealing surfaces.

[0055] As can be seen from the above description, the designed heat insulation member includes a first heat insulation part and a second heat insulation part. In other structural examples, it can further include a third heat insulation part, and the sealing connection of the sealing surface is realized through the auxiliary sealing structure, which can improve the sealing effect of the atmosphere in adjacent temperature zones and further weaken the temperature leakage between temperature zones.

[0056] As a specific structural example, the auxiliary sealing structure 24 includes a convex structure 241 and a concave structure 242 adapted to the convex structure. The first heat insulation part 21 is provided with the convex structure 241 on the sealing surface adjacent to the second heat insulation part, and the second heat insulation part 22 is provided with the concave structure 242 on the sealing surface adjacent to the first heat insulation part.

[0057] As can be seen from the above description, a specific example of the auxiliary sealing structure is provided above, that is, the sealing connection method of the concave-convex engagement of the convex structure and the concave structure is used.

[0058] As a specific structural example, the support base member 1 includes at least one support unit 12. The support unit 12 includes a bearing base surface 121, a first bearing wall 122 and a second bearing wall 123 that are respectively formed by protruding and extending from two ends of the bearing base surface in the first direction, and the positioning part 11 is arranged on the inner surfaces of the first bearing wall 122 and the second bearing wall 123.

[0059] As can be seen from the above description, the above support base member forms a U-shaped or U-shaped cross-section, and the bearing base surface serves as the bottom structure of the support base member. When the production capacity requirement is low, all the adjusting parts can be removed from various corresponding positioning parts. At this time, the first support member supports on the bearing base surface. At this time, the size of the adjusting space formed by enclosing between the first support member and the bottom of the support base member approaches the space formed by the thickness of the structural member itself. Therefore, the overall height space that the sagger formed by the adjusting space and the furnace cavity can pass through is the smallest. It has the advantages of ensuring the support strength and stability while simplifying the structure.

[0060] As a specific structural example, the positioning part 11 includes corresponding first card slots 111 and second card slots 112. The inner surface of the first bearing wall 122 is recessed inward to form the first card slot 111, and the inner surface of the second bearing wall 123 is recessed inward to form the second card slot 112. The first card slot 111 and the second card slot 112 respectively extend in the second direction and are through slots, and both ends of the adjusting part 3 can be slidably clamped in the first card slot 111 and the second card slot 112.

[0061] As can be seen from the above description, by designing the positioning part formed by the corresponding first card slot and second card slot, the adjusting part can be set to be retractable, and the adjusting part can be stably and conveniently withdrawn from or reinserted into the positioning part.

[0062] As a specific structural example, the support base member 1 includes two support units 12 spaced apart along the second direction. The number of the positioning parts 11 and the adjusting parts 3 in each support unit 12 is two respectively. The two positioning parts 11 are sequentially spaced apart by a preset distance along the first direction, and the two adjusting parts 3 are respectively retractably inserted into the two positioning parts 11 in a one-to-one correspondence. The two positioning parts 11 and the two adjusting parts 3 in each support unit 12 correspond to each other one by one.

[0063] As can be seen from the above description, according to the requirements of the furnace body structure, two support units can be designed and installed on two symmetric sides at the junction of the same adjacent temperature zones of the furnace body along the width direction of the furnace body, and both support units are fixed on the top of the furnace body. At this time, in each support unit, two adjusting parts are inserted into the two corresponding positioning parts, and both ends of the first support member along the second direction are simultaneously supported on the adjusting parts in each support unit that are close to the top of the support base member. When it is necessary to disassemble the adjusting parts according to the production capacity requirements, the adjusting parts in each support unit that are close to the top of the support base member are respectively removed, and the adjusting parts immediately below the original adjusting parts close to the top of the support base member become the new adjusting parts close to the top of the support base member, and the first support member is then lowered to the new adjusting parts close to the top of the support base member in each support unit.

[0064] In terms of material selection, the materials of the adjusting part 3, the first support member 4, and the second support member 5 can be the same as the material of the support base member 1, and silicon carbide can be selected for all; the heat insulation part 3 can be selected from known materials with heat insulation effect and capable of blocking fire between adjacent temperature zones, such as ceramic fiber, etc.

[0065] The present application also provides: a sintering device, including a furnace body 6 and at least two driving members 7 rotatably arranged on the side wall of the furnace body 6 along the third direction. A furnace cavity for the passing of the saggers 8 is provided in the furnace body 6, and further includes at least one temperature zone isolation structure of the above-mentioned sintering device, and the temperature zone isolation structure is arranged at the top of the furnace cavity and at the junction of two adjacent temperature zones.

[0066] Based on the above description of the beneficial effects of the temperature zone isolation structure, in the sintering device provided by the present application, the third direction is the sintering advancing direction. By using the design of the temperature zone isolation structure arranged at the top of the furnace cavity and at the junction of two adjacent temperature zones, and adjusting the adjusting space in the temperature zone isolation structure, the height space formed by the adjusting space and the furnace cavity for the passing of the saggers can be adjusted, thereby realizing the adjustability of the furnace type of the sintering device.

[0067] As a specific structural example, the first direction is the height direction of the furnace body, the second direction is perpendicular to the sintering advancing direction, the support base member is fixedly connected to the furnace body, and the heat insulation member covers the junction of two adjacent temperature zones.

[0068] As can be seen from the above description, the first direction is unified with the height direction of the furnace body, the third direction is unified with the sintering advancing direction of the furnace body, the second direction is perpendicular to the third direction, and the heat insulation member covers the junction of two adjacent temperature zones, thereby sealing the preset heat insulation area.

[0069] As a specific structural example, it further includes an air inlet assembly 9, and the air inlet assembly 9 includes a main air inlet pipeline 91, a top air inlet pipeline 92, a side air inlet pipeline 93, and a bottom air inlet pipeline 94;

[0070] The main air inlet pipeline 91 is respectively communicated with the top air inlet pipeline 92, the side air inlet pipeline 93, and the bottom air inlet pipeline 94, and is used for introducing the atmosphere into the top air inlet pipeline 92, the side air inlet pipeline 93, and the bottom air inlet pipeline 94 respectively;

[0071] The air outlet of the top air inlet pipeline 92 is distributed along the second direction and faces the top of the to-be-passed-through sagger 8;

[0072] The air outlet of the side air inlet pipeline 93 is distributed along the third direction and faces the side of the to-be-passed-through sagger 8;

[0073] The air outlet of the bottom air inlet pipeline 94 faces the bottom of the to-be-passed-through sagger 8.

[0074] As can be seen from the above description, in order to cooperate with the adjustment of the furnace type of the sintering device before and after, the present application also designs a matching air inlet assembly, which is an air inlet scheme that can simultaneously introduce air in three directions of the top, side, and bottom.

[0075] As a specific structural example, the air outlet of the top air inlet pipeline 92 is arranged below the heat insulation member 2 and above the to-be-passed-through sagger 8; the air outlet of the side air inlet pipeline 93 is arranged on the side wall of the furnace body 6 and above the transmission member 7; the air outlet of the bottom air inlet pipeline 94 is arranged on the bottom wall of the furnace body 6.

[0076] As can be seen from the above description, according to the above gas path design, it is possible to provide a more comprehensive and sufficient sintering reaction atmosphere for the three directions of the top, side, and bottom of the sagger.

[0077] Please refer to Figures 1 to 15 , Embodiment 1 of the present application is:

[0078] Please refer to Figures 4 - 6, the sintering device of this embodiment includes a furnace body 6, at least two driving members 7, at least two upper heating members 61, at least two lower heating members 62, and a temperature zone isolation structure. The furnace body 1 of this embodiment can select an existing furnace body structure. For example, it is composed of a furnace shell, a furnace pad (refractory and heat-insulating material, such as asbestos, etc.), and a furnace lining (such as refractory bricks, etc.) from outside to inside. A furnace cavity for the placement of the sagger 8 is provided inside the furnace body 1. At least two driving members 7, at least two upper heating members 61, at least two lower heating members 62, and the temperature zone isolation structure are all arranged in the furnace cavity. At least two driving members 7 are spaced apart and are respectively rotatably arranged on the side wall of the furnace body 6 along the sintering advancing direction; at least two upper heating members 61 are spaced apart and are arranged on the side wall of the furnace body 6 along the sintering advancing direction. The upper heating member 61 is arranged above the driving member 7 and parallel to the driving member 7. At least two lower heating members 62 are spaced apart and are arranged on the side wall of the furnace body 6 along the sintering advancing direction. The lower heating member 62 is arranged below the driving member 7 and parallel to the driving member 7. The sagger 8 is placed on the driving member 7 and moves along the sintering advancing direction as the multiple driving members 7 rotate.

[0079] The temperature zone isolation structure is arranged at the top of the furnace cavity and is located at the junction of two adjacent temperature zones. After the temperature zone isolation structure is installed, heat-insulating materials 63, such as heat-insulating bricks, can also be filled between its two sides and the furnace body to prevent the temperature rise on the furnace side from being too high.

[0080] Please refer to Figures 1 - 3 , the temperature zone isolation structure includes a support base member 1 extending along the height direction of the furnace body 6, a heat-insulating member 2 extending along a direction perpendicular to the sintering advancing direction, an adjusting member 3 extending along a direction perpendicular to the sintering advancing direction, a first support member 4 and a second support member 5 respectively extending along a direction perpendicular to the sintering advancing direction. The materials of the support base member 1, the adjusting member 3, the first support member 4, and the second support member 5 are all silicon carbide, and the material of the heat-insulating member 2 is ceramic fiber.

[0081] The heat-insulating member 2 covers the junction of two adjacent temperature zones and is used to seal a preset heat-insulating area. Referring to FIGS. 2-6, in this embodiment, the heat-insulating member 2 includes a first heat-insulating portion 21, a second heat-insulating portion 22, and a third heat-insulating portion 23 that are sequentially and sealingly connected. Figures 2 - 3 The first heat-insulating portion 21, the second heat-insulating portion 22, and the third heat-insulating portion 23 shown are all in a plate-like structure. Refer to Figure 3, the first heat insulation part 21 is provided with a convex structure 241 on the sealing surface adjacent to the second heat insulation part 22, and the third heat insulation part 23 is also provided with a convex structure 241 on the sealing surface adjacent to the second heat insulation part 22. The second heat insulation part 22 is provided with respectively matching concave structures 242 on the sealing surfaces adjacent to the first heat insulation part 21 and the third heat insulation part 23. Through the convex structure 241 and the matching concave structure 242, an auxiliary sealing structure 24 for sealing connection is formed on the adjacent sealing surfaces between the first heat insulation part 21 and the second heat insulation part 22, and between the second heat insulation part 22 and the third heat insulation part 23 respectively. The sealing effect of the furnace atmosphere can be improved, and the temperature leakage between temperature zones can be weakened.

[0082] See Figure 1 , the support base member 1 includes two support units 12. Each support unit 12 includes a bearing base surface 121, a first bearing wall 122 and a second bearing wall 123 which are respectively formed by protruding and extending from two ends of the bearing base surface 121 in the furnace body height direction. The inner surface of the first bearing wall 122 is recessed inward to form two first card slots 111 which are distributed at intervals in the furnace body height direction. The inner surface of the second bearing wall 123 is recessed inward to form two second card slots 112 which are distributed at intervals in the furnace body height direction. The first card slots 111 and the second card slots 112 respectively extend in a direction perpendicular to the sintering advancing direction and are through slots. The two first card slots 111 and the two second card slots 112 are arranged in one-to-one correspondence to form two groups of first card slots and second card slots. Each group of first card slots and second card slots constitutes a positioning part 2; there are two adjusting members 3 in each support unit 12. Two ends of each adjusting member 3 are respectively slidably clamped in a group of first card slots and second card slots with matching heights, and can be pulled along the group of first card slots and second card slots, thereby realizing detachability.

[0083] See Figures 2 - 6 , among the two support units 12, the two support units 12 are respectively fixed at intervals on the top of the furnace body 6 and are symmetrically distributed, that is, the positions of the two support units 12 in the furnace body height direction are corresponding. On this basis, two positioning parts 11 in each support unit 12 are respectively spaced apart by a preset distance in the up and down direction, two adjusting members 3 in each support unit are respectively spaced apart by a preset distance in the up and down direction, and the two positioning parts 11 and the two adjusting members 3 in each support unit 12 are arranged in one-to-one correspondence.

[0084] See Figure 4 , when the production capacity demand is relatively high, the first support member 4 supports on the adjusting member 3 closest to the top in each of the two support units, the second support member 5 supports on the first support member 4, the second support member 5 is a groove structure, and the notch of the groove structure of the second support member 5 faces the top and limits the first heat insulation part 21, the second heat insulation part 22 and the third heat insulation part 23 with sealed connection in the groove structure. Figure 1As shown, the first support member 4 is a hollow square bar structure, such as an existing hollow square beam, and the second support member 5 can be an existing channel steel. At this time, an open adjustment space is formed between the first support member 4 and the bottom surfaces of the respective bearing base surfaces 121 of the two support units 12. The adjustment space and the furnace cavity together form the highest height space through which the sagger 8 can pass. At this time, higher production capacity requirements can be supported, for example, allowing four rows and four layers of sagger bodies to pass through.

[0085] See Figure 5 , when the production capacity demand is average, the adjustment members 3 closest to the top in the two support units can be withdrawn. At this time, the first support member 4 is supported on the remaining adjustment members 3 in the two support units 12 respectively, and the heights of the second support member 5 and the heat insulation member 2 are also lowered in sequence. At this time, an open adjustment space with a smaller height than before is formed between the first support member 4 and the bottom surfaces of the respective bearing base surfaces 121 of the two support units 12. The adjustment space and the furnace cavity together form a lowered height through which the sagger can pass. At this time, average production capacity requirements can be supported, for example, allowing four rows and three layers of sagger bodies to pass through.

[0086] See Figure 6 , when the production capacity demand is low, the remaining adjustment members 3 in the two support units 12 can be withdrawn. At this time, the first support member 4 is supported on the respective bearing base surfaces 121 of the two support units 12, and the heights of the second support member 5 and the heat insulation member 2 are further lowered. At this time, an open adjustment space with a further reduced height is formed between the first support member 4 and the bottom surfaces of the respective bearing bases of the two support units, and this adjustment space approaches the space size corresponding to the thickness of the bearing base surface. The adjustment space and the furnace cavity together form the smallest height space through which the sagger 8 can pass. At this time, lower production capacity requirements can be supported, for example, allowing four rows and two layers of sagger bodies to pass through.

[0087] See Figures 7 - 15 , this embodiment also designs an air intake assembly 9 adapted to the above adjustable furnace type structure. The air intake assembly 9 includes a main air intake pipeline 91, a top air intake pipeline 92, a side air intake pipeline 93, and a bottom air intake pipeline 94; the main air intake pipeline 91 is respectively communicated with the top air intake pipeline 92, the side air intake pipeline 93, and the bottom air intake pipeline 94, and supplies air to the top air intake pipeline 92, the side air intake pipeline 93, and the bottom air intake pipeline 94 through the main air intake pipeline 91. This embodiment also provides control valves 95 on the main air intake pipeline 91, the top air intake pipeline 92, the side air intake pipeline 93, and the bottom air intake pipeline 94, and controls the entry or stop of gas into the corresponding pipelines by controlling the opening or closing of the control valves 95.

[0088] See Figures 7 - 9(The arrows in the figure all indicate the gas flow direction.) In the top inlet pipeline 92 of this embodiment, gas enters the top inlet pipeline 92 from the main inlet pipeline 91. The top inlet pipeline 92 is divided into three pipeline branches, namely the upper branch, the middle branch, and the lower branch. Each of the upper branch, the middle branch, and the lower branch can be further divided into two secondary branches provided on two symmetric sides of the furnace body. Control valves 95 are also provided on the two secondary branches of each of the upper branch, the middle branch, and the lower branch. The two secondary branches of the upper branch correspond to the positions of the adjusting members 3 closest to the top in the two support units 12 one by one and are provided above the adjusting members 3. When the first support member 4 is supported on the adjusting member 3, the air outlets of the two secondary branches of the upper branch face the inside of the first support member 4 (the air outlets of the two secondary branches of the upper branch are provided between the adjusting member 3 closest to the top and the heat insulation member 2); the two secondary branches of the middle branch correspond to the positions of the adjusting members 3 closest to the bottom in the two support units 12 one by one and are provided above the adjusting members 3. When the first support member 4 is supported on the adjusting member 3, the air outlets of the two secondary branches of the middle branch face the inside of the first support member 4 (the air outlets of the two secondary branches of the middle branch are provided between the adjusting member 3 closest to the top and the adjusting member 3 closest to the bottom); the two secondary branches of the lower branch correspond to the positions of the bearing base surfaces 121 in the two support units 12 one by one and are provided above the bearing base surfaces 121. When the first support member 4 is supported on the bearing base surface 121, the air outlets of the two secondary branches of the lower branch face the inside of the first support member 4 (the air outlets of the two secondary branches of the lower branch are provided between the adjusting member 3 closest to the bottom and the bearing base surface 121).

[0089] When the production capacity demand is high, the first support member 4 is supported on the adjusting members 3 closest to the top in the two support units. The air outlets of the two secondary branches of the upper branch extend into the inside of the first support member 4 from both sides of the hollow first support member 4. A plurality of air inlets are opened at the bottom of the first support member 4 (see Figure 14). The control valves 95 of the middle branch and the lower branch are closed, and the control valve 95 of the upper branch is opened. The gas enters the furnace cavity from the air inlets at the bottom of the first support member 4 via the upper branch. The upper branch can mainly ensure the sintering reaction atmosphere of the uppermost sagger materials when the production capacity demand is high.

[0090] When the production capacity demand is average, the adjusting members 3 closest to the top in each of the two supporting units 12 are taken out. At this time, the first support member 4 supports on the remaining adjusting members 3 in each of the two supporting units 12, that is, the adjusting members 3 closest to the bottom. The air outlets of the two secondary branches of the middle layer branch road respectively extend into the interior of the first support member 4 from both sides of the hollow first support member 4. A plurality of air inlets are opened at the bottom of the first support member 4. The control valves 95 of the upper layer branch road and the lower layer branch road are closed, and the control valve 95 of the middle layer branch road is opened. The gas enters the furnace cavity through the air inlets at the bottom of the first support member 4 via the middle layer branch road. The middle layer branch road can mainly ensure the sintering reaction atmosphere of the materials in the uppermost saggers when the production capacity demand is average.

[0091] When the production capacity demand is low, the remaining adjusting members in each of the two supporting units 12 are taken out. At this time, the first support member 4 supports on the respective bearing bases 121 in each of the two supporting units 12. The air outlets of the two secondary branches of the lower layer branch road respectively extend into the interior of the first support member 4 from both sides of the hollow first support member 4. A plurality of air inlets are opened at the bottom of the first support member 4. The control valves 95 of the upper layer branch road and the middle layer branch road are closed, and the control valve 95 of the lower layer branch road is opened. The gas enters the furnace cavity through the air inlets at the bottom of the first support member 4 via the lower layer branch road. The lower layer branch road can mainly ensure the sintering reaction atmosphere of the materials in the uppermost saggers when the production capacity demand is low.

[0092] See Figures 7 - 9 Figs. 15, the arrows in the figures all indicate the gas flow direction. In the side air inlet pipeline 93 of this embodiment, the gas enters the side air inlet pipeline 93 from the main air inlet pipeline 91. The side air inlet pipeline 93 is also divided into three pipeline branches, namely the upper layer branch road, the middle layer branch road and the lower layer branch road. Each of the upper layer branch road, the middle layer branch road and the lower layer branch road can be further divided into two secondary branches provided on the two symmetric sides of the furnace body. Control valves 95 are also provided on the two secondary branches of each of the upper layer branch road, the middle layer branch road and the lower layer branch road. Figures 7 - 9 As shown in Figs. 10 and 15, the air outlets of the two secondary branches of the upper layer branch road, the air outlets of the two secondary branches of the middle layer branch road, and the air outlets of the two secondary branches of the lower layer branch road are all provided on the side wall of the furnace body 6, and are all circular holes arranged at intervals. Each secondary branch of each of the three branches is arranged in a linear hole arrangement, and the overall is arranged in three rows of parallel linear holes in the upper, middle and lower layers. The positions of the air outlets of the two secondary branches of the upper layer branch road can correspond to the positions of the higher saggers when the production capacity demand is high. The positions of the air outlets of the two secondary branches of the middle layer branch road can correspond to the positions of the higher saggers when the production capacity demand is average. The positions of the air outlets of the two secondary branches of the lower layer branch road can correspond to the positions of the saggers when the production capacity is relatively low.

[0093] In this way, when the production capacity demand is high, for example, when four rows of four layers of saggers pass through, the atmosphere enters through the side air inlet pipe 93. At this time, it is necessary to open the control valve 95 on the upper branch, the control valve 95 on the middle branch, and the control valve 95 on the lower branch to provide atmosphere for the materials on each layer of the four rows of four layers of saggers.

[0094] When the production capacity demand is normal, for example, when four rows of three layers of saggers pass through, the atmosphere enters through the side air inlet pipe 93. At this time, it is necessary to close the control valve 95 on the upper branch (to prevent the airflow from running around in the horizontal direction inside the furnace body, causing temperature running between different temperature zones), open the control valve 95 on the middle branch and the control valve 95 on the lower branch, and provide atmosphere for the materials on each layer of the four rows of three layers of saggers.

[0095] When the production capacity demand is low, for example, when four rows of two-layer saggers pass through, the atmosphere enters through the side air inlet pipe 93. At this time, it is necessary to close the control valve 95 on the upper branch and the control valve 95 on the middle branch (to prevent the air flow from running around in the horizontal direction inside the furnace body, causing temperature running between different temperature zones), and open the control valve 95 on the lower branch to provide atmosphere for the materials on each layer of the four rows of two-layer saggers.

[0096] See also Figure 13 In this embodiment, the air inlet holes arranged in an "I" shape are designed at the bottom of the furnace. The air inlet holes arranged in an "I" shape are distributed around the bottom of the sagger 8. Specifically, the gas enters the bottom air inlet pipeline 94 from the main air inlet pipeline 91. The bottom air inlet pipeline 94 is divided into two pipeline branches arranged on different sides of the furnace body 6. The gas enters the bottom of the furnace body through the two pipeline branches from the air inlet holes arranged in an "I" shape connected thereto. Figure 13 The air inlet holes shown are circular holes, and a series of air inlet holes arranged in an "I" shape are used to supply air to the bottom of the furnace body to form an atmosphere. The bottom air inlet pipeline 94 mainly ensures the atmosphere of the gap between the furnace body and the bottom of the sagger in the preset temperature zone.

[0097] Below, the use principle of this embodiment is explained by taking specific working conditions as examples. Specifically, four-row four-layer sagger sintering is taken as the working condition when the production capacity demand is high, four-row three-layer sagger sintering is taken as the working condition when the production capacity demand is general, and four-row two-layer sagger sintering is taken as the working condition when the production capacity demand is low. The explanation is as follows.

[0098] Sintering conditions of four-row four-layer saggers: When the upper adjustment piece (i.e., the adjustment piece close to the top of the supporting base) is used, the part below the adjustment piece is sealed with filling insulation bricks. At this time, the space formed by the adjustment space and the furnace cavity has the highest height, which can be used for four-row four-layer saggers to pass through the furnace. When the temperature zone isolation structure meets the requirements of four-row four-layer saggers passing through, the top air intake pipeline and the side air intake pipeline of the kiln need to be adjusted at the same time. The top air intake pipeline is adjusted as follows: open the control valve (such as a ball valve) on the upper branch of the top air intake pipeline, close the control valve on the middle branch of the top air intake pipeline, and close the control valve on the lower branch of the top air intake pipeline. At this time, the upper branch of the top air intake pipeline provides a sintering reaction atmosphere for the materials in the four-row four-layer top saggers. The side air intake pipeline is adjusted as follows: when the four-row four-layer sagger materials are sintered, the materials in the three layers of saggers at the bottom all need a sintering reaction atmosphere, and the atmosphere can enter through the openings around the saggers. At this time, it is necessary to open the control valve (such as a ball valve) on the upper branch of the side air intake pipeline (ventilation of the upper branch of the side air intake pipeline), open the control valve on the middle branch of the side air intake pipeline (ventilation of the middle branch of the side air intake pipeline), and open the control valve on the lower branch of the side air intake pipeline (ventilation of the lower branch of the side air intake pipeline). The control valve on the total air intake pipeline is guaranteed to be in the open state to meet the bottom air intake demand.

[0099] Sintering condition of four-row three-layer saggers: when using the lower-layer adjustment parts (i.e. the adjustment parts close to the bottom of the supporting base), remove the upper-layer adjustment parts. At this time, the furnace structure can meet the needs of four-row three-layer saggers; when the temperature zone isolation structure meets the needs of four-row three-layer saggers, the top air intake pipeline and the side air intake pipeline of the kiln need to be adjusted at the same time. The top air intake pipeline is adjusted as follows: only open the control valve on the middle branch of the top air intake pipeline, close the control valve on the upper branch of the top air intake pipeline, and close the control valve on the lower branch of the top air intake pipeline. At this time, the middle branch provides sintering reaction atmosphere for the materials in the four-row three-layer top saggers. The side air intake pipeline is adjusted as follows: When the materials in the four-row three-layer saggers are sintered, the materials in the two bottom layers of saggers need a sintering reaction atmosphere, and the atmosphere can enter through the openings around the saggers. At this time, it is necessary to open the control valve on the middle branch of the side air intake pipeline (ventilation of the middle branch of the side air intake pipeline) and open the control valve on the lower branch of the side air intake pipeline (ventilation of the lower branch of the side air intake pipeline). At the same time, it is necessary to close the control valve on the upper branch of the side air intake pipeline (gas cutoff of the upper branch of the side air intake pipeline) to prevent the air flow from running around in the horizontal direction inside the furnace body, resulting in temperature runaway in different temperature ranges. The control valve on the total air intake pipeline is kept open to meet the bottom air intake demand.

[0100] Sintering conditions of four-row two-layer saggers: When the upper and lower adjustment parts are not installed, the first support is directly installed on the bearing base surface, which can meet the use of four-row two-layer saggers. When the temperature zone isolation structure meets the requirements of four-row two-layer saggers, the top air intake pipeline and the side air intake pipeline of the kiln need to be adjusted at the same time. The top air intake pipeline is adjusted as follows: only open the control valve on the lower branch of the top air intake pipeline, close the control valve on the upper branch of the top air intake pipeline, and close the control valve on the middle branch of the top air intake pipeline. At this time, the lower branch provides sintering reaction atmosphere for the materials in the four-row two-layer top sagger. The side air intake pipeline is adjusted as follows: When the four-row two-layer sagger materials are sintered, the materials in the bottom layer of the sagger need sintering reaction atmosphere, and the atmosphere can enter through the openings around the sagger. At this time, the control valve on the lower branch of the side air intake pipeline needs to be opened (the lower branch of the side air intake pipe is ventilated). At the same time, it is necessary to close the control valve on the upper branch of the side air intake pipe (the upper branch of the side air intake pipe is cut off) and the control valve on the middle branch of the side air intake pipe (the middle branch of the side air intake pipe is cut off) to prevent the air flow from running around in the horizontal direction inside the furnace body, causing temperature fluctuations in different temperature zones. The control valve on the main air intake pipe is kept open to meet the bottom air intake demand.

[0101] In the whole furnace type conversion process, this embodiment includes two steps: adjusting the height of the first support member and adjusting the air intake assembly. The first support member does not need to be disassembled, and only the adjustment member needs to be disassembled, which is very simple and light. The air intake assembly only needs to adjust the top air intake pipeline and the side air intake pipeline through the corresponding control valve, and the bottom air intake pipeline does not need to be adjusted.

[0102] In summary, the temperature zone isolation structure provided in the present application can realize the adjustable furnace type of the sintering device through the structural adjustable design of the temperature zone isolation device. In the process of adjusting the height, it is only necessary to disassemble and assemble the adjusting parts, which is simple and easy to operate and has high replacement efficiency; the height of the partition beam can be adjusted without changing the frame structure of the furnace body, so that it can be compatible with different numbers of sagger layers passing through the furnace cavity; the sintering device including the above-mentioned temperature zone isolation structure provided in the present application is designed with an adjustable air intake structure of the air intake component matching the structural adjustable design of the temperature zone isolation device, and the top air intake pipeline is divided into three independently controlled The side air intake pipeline is also divided into three independently controlled branches, and each pipeline is divided into secondary branches located on the left and right symmetrical sides of the furnace body. The three branches are opened and closed according to the production conditions of different sagger layers to meet the top air intake demand of the top sagger; the side air intake pipeline is also divided into three independently controlled branches, and each pipeline is divided into secondary branches located on the left and right symmetrical sides of the furnace body. The three branches are opened and closed according to the production conditions of different sagger layers to meet the side air intake demand of the stacked saggers except the top sagger; the main air intake pipeline is divided into top air intake pipeline, side air intake pipeline and bottom air intake pipeline, and the three pipelines are controlled separately and independently without affecting each other.

Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall similarly be included within the patent protection scope of the present invention.
