Description

Technical Field

[0001] The utility model belongs to the field of kiln loading and unloading, and specifically relates to a kiln heat insulation section. Background Art

[0002] A kiln is a furnace that performs protective firing on heated items in a vacuum environment and protective atmosphere. The furnace contains protective gas and high temperature. Taking the atmosphere-protected roller kiln as an example, its basic working principle is: using a motor to drive multiple rows of rollers to rotate, the powder material in the graphite sagger is continuously fed into a closed furnace body that is tens of meters long, and after being sintered at a high temperature of about 800-1000℃, it is taken out of the furnace and enters the next process. The roller kiln has the advantages of uniform temperature, short firing cycle, and stable operation.

[0003] The furnace body of the traditional atmosphere roller kiln is divided into a preheating section, a heating constant temperature section, and a cooling section. The heating constant temperature section and the cooling section are interconnected. The high-temperature gas generated in the heating constant temperature section directly enters the cooling section and enters the furnace gas recovery system along with the exhaust gas, causing a great loss of heat and energy, a lot of waste of electricity, and high energy consumption costs.

[0004] Therefore, it is now necessary to develop a kiln insulation section, which can be used for continuous loading of the kiln heating constant temperature section or continuous unloading to the unloading end or continuous unloading to the cooling section, so as to reduce heat loss between the heating constant temperature section and the cooling section, reduce energy consumption, improve energy utilization, and thus significantly reduce production costs.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] It should be noted that in the present invention, when the heat insulation section is the lower end of the heating constant temperature section, the material conveying mechanism 11 conveys materials toward the material transfer platform; the pull / push mechanism 3 is used to pull the materials of the material conveying mechanism 11 onto the material transfer platform 13, that is, it is used as a material pulling mechanism; the push / pull mechanism 2 is used to push the materials of the material transfer platform 13 out of the furnace door mechanism 14, that is, it is used as a material pushing mechanism; accordingly, at this time, the lower / upstream end of the material conveying mechanism 11 represents the downstream end of the material conveying mechanism 11, and the lower / upstream section of the material conveying mechanism 11 represents the downstream part of the material conveying mechanism 11; the material pull / push block 36 is used to pull materials; the material push / pull block is used to push materials; the material inlet / outlet end 132 is the material entry end; the material inlet / outlet end 133 is the material exit end;

[0040] When the heat insulation section is the feeding end of the heating constant temperature section, the material conveying mechanism 11 conveys materials away from the material transfer platform; the push / pull mechanism 2 is used to pull the materials outside the furnace door mechanism 14 into the material transfer platform 13, that is, it is used as a pulling mechanism; the pull / push mechanism 3 is used to push the materials on the material transfer platform 13 into the material conveying mechanism 11, that is, it is used as a pushing mechanism; accordingly, at this time, the lower / upstream end of the material conveying mechanism 11 represents the upstream end of the material conveying mechanism 11, and the lower / upstream section of the material conveying mechanism 11 represents the upstream part of the material conveying mechanism 11; the material pull / push block 36 is used to push the material; the material push / pull block is used to pull the material; the material inlet / outlet end 132 is the material outlet end; the material inlet / outlet end 133 is the material inlet end;

[0041] That is, the push / pull mechanism 2, the pull / push mechanism 3, the lower / upstream end of the material conveying mechanism 11, the lower / upstream section of the material conveying mechanism 11, the material pull / push block 36 and the material push / pull block in the utility model can be used solely as a loading end structure or solely as a unloading end structure according to the material conveying method of the material conveying mechanism 11, and can also have the functions of the loading end and the unloading end at the same time. After the material conveying method of the material conveying mechanism 11 is switched, the functions of the above-mentioned structures can be switched immediately.

[0042] As attached Figure 1 -Attached Figure 7 As shown, the utility model provides a kiln insulation section, including an insulation furnace body 1, a push / pull mechanism 2 and a pull / push mechanism 3, wherein the insulation furnace body 1 is the upstream connection end or the downstream connection end of the heating constant temperature section of the kiln, and can be used as a preheating section when serving as the upstream connection end, and can be used to connect the cooling section when serving as the downstream connection end;

[0043] A material conveying mechanism 11 is provided in the insulated furnace body 1, which is used to carry and convey the material. That is, the kiln provided in the present application is a continuous production kiln. The material can be continuously loaded to the heating constant temperature section through the insulation section, and move in the heating constant temperature section for a set time to complete the firing of the material, that is, the insulated furnace body 1 serves as a continuous loading device for the heating constant temperature section, or the material is unloaded to the cooling section through the insulation furnace body 1 after being fired in the heating constant temperature section, that is, the insulated furnace body 1 serves as a continuous unloading device for the heating constant temperature section.

[0044] A material transfer platform 13 is provided at the lower / upstream end of the material conveying mechanism 11. The material transfer platform 13 is used to receive materials to be unloaded or loaded. The materials enter the material transfer platform 13 from the lower / upstream end of the material conveying mechanism 11 for unloading operations. Preferably, the materials slide by friction on the material transfer platform 13, which can avoid inertial sliding of the materials during the unloading process caused by excessive gravity of the materials, thereby improving the stability of the unloading process. The heat-insulating furnace body 1 is provided with an openable and closable furnace door mechanism 14 on the side of the material transfer platform 13. The furnace door mechanism 14 includes an opening 141 on the heat-insulating furnace body 1 and a furnace door 142 that can open and close the opening 141. The furnace door mechanism 14 is used to control the opening and closing of the opening 141, and then open the opening 141 when it is necessary to unload or load materials, so as to facilitate the materials to leave or enter the interior of the heat-insulating furnace body 1, and close the opening 141 when it is not necessary to unload materials, so as to avoid the high temperature in the heat-insulating furnace body 1 from escaping from the opening 141.

[0045] The lower / upstream section of the material conveying mechanism 11 includes a plurality of conveying rollers 111 and a driving assembly 112 for driving the conveying rollers 111 to rotate. The conveying rollers 111 are connected to the driving assembly 112 through a one-way clutch mechanism 113. The rotation direction of the conveying rollers 111 is opposite to the limiting direction of the one-way clutch mechanism 113. When the material pulling speed of the pull / push mechanism 3 is faster than the conveying speed of the conveying rollers 111 of the lower / upstream section of the material conveying mechanism 11, the one-way clutch mechanism 113 is idle, and the corresponding conveying roller 111 rotates faster than the rotation speed of the output end of the driving assembly 112 until the material leaves the conveying roller 111 and enters the material transfer platform 13, thereby realizing that the material will not generate friction with the lower / upstream section of the material conveying mechanism 11 during the process of the pull / push mechanism 3 quickly pulling the material into the material transfer platform 13, thereby improving the use stability and reliability of the lower / upstream section of the material conveying mechanism 11 on the basis of improving the material unloading or loading efficiency, and at the same time improving the stability of material movement.

[0046] It should be noted that the downstream / upstream section of the material conveying mechanism 11 is a roller conveying mechanism, while the upstream section and midstream section of the material conveying mechanism 11 can adopt other conveying mechanisms available for the kiln, and of course, a roller conveying mechanism can also be adopted, and there is no need to equip the one-way clutch mechanism 113 between the conveying roller 111 and the driving assembly 112. Preferably, the conveying roller 111 is rotatably arranged on a bracket in the heat-insulating furnace body 1 through a bearing, and the driving assembly 112 includes a transmission main shaft 1121 and a plurality of driven shafts 1123 meshed with the transmission main shaft 1121 through a bevel gear set 1122, one driven shaft 1123 is connected to one conveying roller 111, and the one-way clutch mechanism 113 is arranged on the driven shaft 1123. Preferably, the one-way clutch mechanism 113 can be a one-way bearing, a ratchet or an overrunning clutch;

[0047] When the heat-insulating section of the kiln is used as the unloading section of the heating constant temperature section, the pull / push mechanism 3 is used to pull the material in the lower / upstream section of the material conveying mechanism 11 onto the material transfer platform 13, so that the material is separated from the material conveying mechanism 11 and enters the material transfer platform 13 during the unloading process, so as to facilitate stable and reliable unloading of the material. The push / pull mechanism 2 is used to push the material on the material transfer platform 13 out of the furnace door mechanism 14. In the process of the material entering and leaving the material transfer platform 13, the material frictionally slides on the material transfer platform 13 at this time, and the material can be pushed quickly without causing inertial slip of the material and without causing a burden on the material conveying mechanism 11, so that the material can quickly leave the heat-insulating furnace body 1, shorten the time when the furnace door mechanism 14 is in the open state, reduce heat loss, and reduce energy consumption on the basis of ensuring unloading efficiency and unloading stability.

[0048] When the heat-insulating section of the kiln is used as the loading section of the heating constant temperature section, the pull / push mechanism 3 is used to push the material on the material transfer platform 13 into the upstream section of the material conveying mechanism 11, and the push / pull mechanism 2 is used to pull the material outside the furnace door mechanism 14 into the material transfer platform 13, and has the same effect as when the unloading section of the heating constant temperature section is used.

[0049] The kiln insulation section provided by the utility model can be used for unloading and loading materials in the heating constant temperature section of the kiln. By configuring a one-way clutch mechanism 113 on the conveying roller 111 in the lower / upstream section of the material conveying mechanism 11 and combining it with the pull / push mechanism 3, it can provide a much faster conveying speed than the conveying roller 111 (the conveying speed of the conveying roller 111 in the kiln is very slow) for unloading or loading materials. In addition, by setting a material transfer platform 13 and combining it with the push / pull mechanism 2, the material can be quickly and stably sent out or pulled into the insulation furnace body 1 without inertial slip, thereby shortening the time when the furnace door mechanism 14 is in the open state, reducing heat loss, and reducing energy consumption on the basis of ensuring unloading efficiency and unloading stability.

[0050] In one of the embodiments, the opening direction of the furnace door mechanism 14 is perpendicular to the conveying direction of the material conveying mechanism 11. At this time, the opening 141 of the furnace door mechanism 14 is set on the side of the insulating furnace body 1 instead of its conveying direction, so that the material transportation and the material unloading or loading can turn at a 90° angle, which can reduce the transmission efficiency of the high temperature inside the insulating furnace body 1, thereby reducing the heat loss rate from the opening 141 in the insulating furnace body 1, and further reducing heat loss.

[0051] In one embodiment, the material is a rectangular structure, and the long side of the material moves on the material conveying mechanism 11 parallel to the axial direction of the conveying roller 111; the material is discharged from the furnace door mechanism 14 along the length direction. In this embodiment, the long side of the material moves on the material conveying mechanism 11 parallel to the axial direction of the conveying roller 111, which can increase the material transmission volume of the heat-insulating furnace body 1, thereby improving the firing efficiency. On this basis, the area of ​​the opening 141 of the furnace door mechanism 14 only needs to be larger than the cross-sectional area of ​​the material, which can greatly reduce the area of ​​the opening 141 of the furnace door mechanism 14, further reduce heat loss, reduce energy consumption, and at the same time, the material does not need to switch direction during the entire unloading or loading process, simplifying the difficulty of unloading the material.

[0052] In one of the embodiments, the pulling / pushing mechanism 3 is arranged on the end wall of the lower / upstream end of the insulating furnace body 1, that is, the pulling / pushing mechanism 3 is arranged at the end or the head end of the insulating furnace body 1. At this time, the output end of the pulling / pushing mechanism 3 extends into the lower / upstream section of the material conveying mechanism 11 to pull the material to the material transfer platform 13. On the one hand, it can prevent the main part of the pulling / pushing mechanism 3 from invading the material conveying mechanism 11 and occupying the space of the insulating furnace body 1 located in the material conveying mechanism 11. On the other hand, it can prevent the main part of the pulling / pushing mechanism 3 from invading the space of the insulating furnace body 1 located in the material conveying mechanism 11, thereby preventing the main part of the pulling / pushing mechanism 3 from being located in the highest temperature environment, thereby improving its use stability.

[0053] In one embodiment, the pull / push mechanism 3 includes a first linear drive mechanism 31, a connecting rod 32 and a material pull / push block 36;

[0054] The first linear drive mechanism 31 is fixedly arranged outside the heat-insulating furnace body 1, so that the first linear drive mechanism 31 can be located outside the heat-insulating furnace body 1, so that the first linear drive mechanism 31 and the rotary drive mechanism can avoid the high temperature, dust, and turbulent environment inside the heat-insulating furnace body 1, reduce the performance requirements for the first linear drive mechanism 31 and the rotary drive mechanism, and improve the use stability and service life;

[0055] The furnace wall of the heat-insulating furnace body 1 is provided with a mounting hole 15, and the connecting rod 32 is dynamically sealed with the furnace wall of the heat-insulating furnace body 1. Specifically, the connecting rod 32 is dynamically sealed with the mounting hole 15, that is, the connecting rod 32 can linearly reciprocate and rotate on the furnace wall of the heat-insulating furnace body 1, and at the same time ensure the sealing of the furnace wall to prevent the heat in the heat-insulating furnace body 1 from being lost through the mounting hole 15. The connecting rod 32 is located at one end outside the furnace of the heat-insulating furnace body 1 and is rotatably matched with the output end of the first linear driving mechanism 31. The first linear driving mechanism 31 is used to drive the connecting rod 32 to linearly reciprocate along its axis. A material pulling / pushing block 36 is fixed at one end inside the furnace of the heat-insulating furnace body 1. The material pulling / pushing block 36 is used to pull or push the material to move. When pulling the material to move, the material pulling / pushing block 36 is engaged with the material or hooked by rotating; when pushing the material to move, the material pulling / pushing block 36 abuts against the end of the material to push.

[0056] A rotary drive mechanism is provided on the output end of the first linear drive mechanism 31, and the rotary drive mechanism is used to drive the connecting rod 32 to rotate, thereby rotating the material pull / push block 36 to connect with or separate from the material in the insulation furnace body 1, wherein the material pull / push block 36 is connected with the material, which means that the material pull / push block 36 is engaged with the material, and the material pull / push block 36 is located at the lower / upstream end of the material to hook the material or abut against and push the material, so that the material pull / push block 36 pulls the material to move under the drive of the first linear drive mechanism 31. The separation of the material pulling / pushing block 36 from the material means that the material pulling / pushing block 36 leaves the moving path of the material by rotating, and the material will not touch the material pulling / pushing block 36 during movement. At this time, the material pulling / pushing block 36 can be extended to the lower / upstream end of the material conveying mechanism 11 through the connecting rod 32 to complete the preparation work of pulling the material. After the material is conveyed to the lower / upstream end of the material conveying mechanism 11, the material pulling / pushing block 36 can be rotated by the rotating driving mechanism to connect the material pulling / pushing block 36 with the material and start the material pulling operation.

[0057] The pull / push mechanism 3 provided in this embodiment is used to realize that the drive mechanism (first linear drive mechanism 31 and rotary drive mechanism) located outside the heat-insulating furnace body 1 pulls the material in the furnace of the heat-insulating furnace body 1, so that the first linear drive mechanism 31 and the rotary drive mechanism can avoid the high temperature, dust and turbulent environment inside the warehouse, reduce the performance requirements of the first linear drive mechanism 31 and the rotary drive mechanism, and improve the stability and service life of use. In addition, the connecting rod 32 cooperates with the warehouse wall of the heat-insulating furnace body 1 in a dynamic seal, so that the connecting rod 32 can rotate and slide on the warehouse wall of the heat-insulating furnace body 1, and always maintain the sealing effect with the warehouse wall, avoiding the heat loss in the heat-insulating furnace body 1, and the cooperation relationship between the rotary drive mechanism, the first linear drive mechanism 31 and the connecting rod 32 enables the connecting rod 32 to drive the material pulling / pushing block 36 to move back and forth and rotate, so as to pull the material and separate it from the material. The overall structure is simple and reliable, the docking with the material is convenient and stable, and the pulling efficiency of the material is high.

[0058] Preferably, the connecting rod 32 is connected to the output end of the first linear drive mechanism 31 through a bearing; the bearing bears a bidirectional axial load, that is, the connecting rod 32 can rotate on the output end of the first linear drive mechanism 31 and can withstand the push-pull axial force of the material pull / push block 36.

[0059] Preferably, the first linear drive mechanism 31 is a linear module, which has the characteristics of strong load-bearing capacity and stable movement of the output slider, and can ensure that the connecting rod 32 can move accurately and reliably under load. Preferably, the first linear drive mechanism 31 is fixed on the bracket;

[0060] The slide plate of the linear module is provided with a vertical support plate 37 arranged perpendicular to the moving direction of the slide plate. Preferably, a horizontal mounting plate is provided at the bottom of the vertical support plate 37, and the horizontal mounting plate is fixedly provided on the slide plate of the linear module to simplify the installation of the vertical support plate 37 and improve the installation stability of the vertical support plate 37. The vertical support plate 37 is provided with a connecting rod mounting hole 371 for rotatably mounting the connecting rod 32, and the outer wall of the connecting rod 32 and the connecting rod mounting hole 371 are connected by a bearing.

[0061] Preferably, the rotary drive mechanism includes a rotary drive member 34 arranged on the vertical support plate 37 and a transmission mechanism arranged between the rotary drive member 34 and the connecting rod 32. The rotary drive member 34 can be a rotary motor, a rotary cylinder or a rotary oil cylinder, and can be rotated according to actual needs. The transmission mechanism is used to transmit the rotational force of the rotating shaft of the rotary drive member 34 to the connecting rod 32, so that the connecting rod 32 can rotate around its axial direction.

[0062] Preferably, the transmission mechanism is gear transmission, chain transmission or belt transmission. Preferably, the transmission mechanism adopts gear transmission, including a driving gear 35 arranged on the rotating shaft of the rotating driving member 34 and a driven gear 33 arranged on the outer wall of the connecting rod 32. The driving gear 35 and the driven gear 33 are meshed for transmission. The gear transmission has the characteristics of strong load-bearing capacity and precise control, which can ensure the precise steering of the material pulling / pushing block 36.

[0063] In one embodiment, two groups of pull / push mechanisms 3 are symmetrically arranged on one side of the heat-insulating furnace body 1; the two groups of pull / push mechanisms 3 work synchronously. In this embodiment, the two groups of pull / push mechanisms 3 perform synchronous pulling operations on both sides of the material, so that the material can be moved accurately without deviation, and can enter the material transfer platform 13 accurately.

[0064] In one of the embodiments, the push / pull mechanism 2 is arranged on the side wall of the lower / upstream end of the insulating furnace body 1; and the push / pull mechanism 2 is arranged on the insulating furnace body 1 and on the side opposite to the furnace door mechanism 14; preferably, the push / pull mechanism 2 has the same structure as the pull / push mechanism 3 (not shown in the figure, the figure shows an embodiment in which the push / pull mechanism 2 is a pushing mechanism), at this time, the material push / pull block of the push / pull mechanism 2 is used to connect or separate with the material, thereby pushing or pulling the material to move.

[0065] Reference Figure 5 In one embodiment, when the lower end of the heat insulation section is a heating constant temperature section and is used as a material discharge device, the push / pull mechanism 2 includes a second linear drive mechanism 21 and a drive rod 22 disposed on the output end of the second linear drive mechanism 21;

[0066] The second linear drive mechanism 21 is fixedly arranged outside the heat-insulating furnace body 1, so that the second linear drive mechanism 21 is away from the harsh environment of the heat-insulating furnace body 1 with high temperature, turbulent airflow, and a lot of impurities such as dust and tar, thereby reducing the performance requirements of the second linear drive mechanism 21 and improving the use stability and service life of the second linear drive mechanism 21;

[0067] The driving rod 22 is dynamically sealed and fitted on the side wall of the insulated furnace body 1, that is, the driving rod 22 can slide back and forth in the mounting hole 15. During the sliding process, the driving rod 22 can continuously maintain the sealing of the mounting hole 15 to avoid heat loss in the insulated furnace body 1. The driving rod 22 is located at one end of the insulated furnace body 1 inside the furnace and is used to push the material to the furnace door mechanism 14.

[0068] Preferably, the end of the driving rod 22 located in the insulating furnace body 1 can be detachably matched with the pushing block 23, that is, the pushing block 23 is used to push the material to move. Since the pushing block 23 is a structure that contacts the material, it can be made of high-temperature resistant and wear-resistant materials, such as graphite, to increase the service life, and the requirements of the driving rod 22 can be reduced, thereby reducing costs. Preferably, the pushing block 23 is detachably arranged at the end of the driving rod 22 by fasteners, thereby facilitating the replacement of the pushing block 23.

[0069] In one embodiment, an insulation layer 12 is provided on the inner wall of the insulated furnace body 1; preferably, the insulation layer 12 includes a frame 121 and a refractory material 122 arranged in the frame 121, and the refractory material 122 is preferably composed of ceramic fiber board, ceramic fiber wool, etc., and is fixed to the frame 121 by an anchor.

[0070] The insulation layer 12 is provided with a sliding hole 123 for the output ends of the push / pull mechanism 2 and the pull / push mechanism 3 to slide. The output ends of the push / pull mechanism 2 and the pull / push mechanism 3 are adapted to the cross-sectional shape of the sliding hole 123, that is, the push block 23 or the material push / pull block of the push / pull mechanism 2, and the cross-sectional shape of the material pull / push block 36 of the pull / push mechanism 3 are adapted to the cross-sectional shape of the sliding hole 123. In this way, the pushing block 23 or the material push / pull block and the material pull / push block 36 can slide along the sliding hole 123 and then extend into the furnace to push / pull the material, and can also stay in the sliding hole 123 to ensure the sealing effect of the insulation layer 12. When the pushing block 23 and the material pull / push block 36 retract into the sliding hole 123, the gap caused by the sliding hole 123 of the insulation layer 12 is filled, thereby ensuring the integrity of the insulation layer 12 and then ensuring the sealing effect of the insulation furnace body 1. At the same time, the driving rod 22 and the connecting rod 32 can also leave the space in the furnace to avoid interfering with the movement of materials in the furnace.

[0071] In one of the embodiments, the material transfer platform 13 includes a middle material carrying area 131, a material inlet / outlet end 132 close to the material conveying mechanism 11, a material inlet / outlet end 133 close to the furnace door mechanism 14, a driving rod pushing end 134 close to the push / pull mechanism 2, and a material limiting block 135 close to one end of the pull / push mechanism 3, and the material limiting block 135 is flush with the opening side of the furnace door mechanism 14. In this embodiment, when the insulation section is the lower end of the heating constant temperature section, the material enters the material carrying area 131 from the material inlet / outlet end 132, and is limited and positioned by the material limiting block 135, which can conveniently and quickly complete the positioning of the material after pulling, and then the pushing block 23 or the material pushing / pull block pushes the material from the material inlet / outlet end 133 into the furnace door mechanism 14 from the driving rod pushing end 134, which can improve the material unloading efficiency and stability. When the insulation section is the loading end of the heating constant temperature section, the material enters the material carrying area 131 from the material inlet / outlet end 133 and is guided by the material limit block 135, so that the material can be easily and quickly positioned after pulling the material, and then the material pulling / pushing block 36 pushes the material from the material inlet / outlet end 132 to the material conveying mechanism 11.

[0072] Preferably, the material transfer platform 13 includes a bottom plate 136 and a graphite plate 137, and the graphite plate 137 is fixed to the bottom plate 136 by graphite bolts. The contact part between the material transfer platform 13 and the material is made of graphite material, which has the characteristics of high temperature resistance and wear resistance, and improves the service life. Preferably, a plurality of stainless steel support tubes 16 are welded to the bottom of the furnace of the heat-insulating furnace body 1, and a graphite adjustment rod 17 is inserted at the upper end of the support tube 16. The graphite adjustment rod 17 is connected to the bottom plate 136 by threads. Rotating the graphite adjustment rod 17 can adjust the height and level of the bottom plate 136, and then adjust the height and level of the graphite plate 137 connected to it by graphite bolts.

[0073] Preferably, the material stopper 135 is also made of graphite, and the rear end of the graphite plate 137 is connected to the material stopper 135 by a graphite bolt. A sleeve 18 is welded to the rear side of the frame 121 in the heat-insulating furnace body 1, and a graphite push rod 19 is sleeved in the sleeve 18. The rear end of the sleeve 18 is threadedly connected with a set screw 110. By adjusting the position of the set screw 110, the extension length of the graphite push rod 19 can be adjusted, so that the material stopper 135 can support the graphite plate 137.

[0074] In one embodiment, the utility model further includes a material position adjustment mechanism 4, which is arranged on both sides of the lower / upstream section of the heat-insulating furnace body 1 located at the material conveying mechanism 11, and includes a push plate driving member 42 arranged outside the heat-insulating furnace body 1 and a push plate 41 arranged inside the heat-insulating furnace body 1, and the push plate 41 is connected to the push plate driving member 42 through a sliding rod 43 on the side wall of the heat-insulating furnace body 1 through a sealed sliding connection, and the two sets of material position adjustment mechanisms 4 are used to adjust the position of the material on the lower / upstream section of the material conveying mechanism 11. Specifically, when the material passes through the lower / upstream section of the material conveying mechanism 11 and passes through the material position adjustment mechanism 4, the two sets of material position adjustment mechanisms 4 simultaneously drive the push plate 41 to move, so that the material moves to the middle position of the lower / upstream section of the material conveying mechanism 11, thereby facilitating the two sets of pull / push mechanisms 3 to accurately dock with the material.

[0075] The utility model also provides a material transfer method of a heat-insulating section of a kiln, using the heat-insulating section of the kiln, including a material loading mode of a heating constant temperature section and a material unloading mode of a heating constant temperature section;

[0076] The material feeding mode of the heating constant temperature section comprises the following steps:

[0077] S11, controlling the furnace door mechanism 14 to open, and pulling the material from the outside of the furnace door mechanism 14 into the material transfer platform 13 through the push / pull mechanism 2;

[0078] S12, control the furnace door mechanism 14 to close, and push the material on the material transfer platform 13 into the upstream section of the material conveying mechanism 11 through the pull / push mechanism 3. During the pushing process, the moving speed of the material is greater than the normal conveying speed of the conveying roller 111, and the conveying roller 111 of the upstream section of the material conveying mechanism 11 is accelerated to rotate through the one-way clutch mechanism 113; avoid the material and the conveying roller 111 of the lower / upstream section of the material conveying mechanism 11 to generate slip friction, thereby reducing the service life of the conveying roller 111 of the lower / upstream section of the material conveying mechanism 11; in addition, in this step, since the material moves by friction and sliding on the material transfer platform 13, no inertial slip will occur, so the material pulling speed can be accelerated, thereby shortening the opening time of the furnace door mechanism 14, reducing heat loss, and reducing energy consumption;

[0079] S13, the material completely enters the material conveying mechanism 11, and is conveyed to the heat-insulating furnace body 1 to the heating constant temperature section through the material conveying mechanism 11;

[0080] Repeat steps S11-S13 to continuously load materials in the heating constant temperature section;

[0081] The material unloading mode in the heating constant temperature section comprises the following steps:

[0082] S21, a plurality of materials are sintered and moved in sequence in the heat-insulating furnace body 1 through the material conveying mechanism 11. Preferably, the materials are moved at a uniform speed on the material conveying mechanism 11, and the materials are moved from the feeding end to the unloading section of the heat-insulating furnace body 1 for a set time to ensure the sintering effect;

[0083] S22, the material at the most upstream will enter the lower / upstream section of the material conveying mechanism 11. At this time, the pulling / pushing mechanism 3 will pull the material at the lower / upstream section of the material conveying mechanism 11 onto the material transfer platform 13. During the pulling process, the moving speed of the material is greater than the normal conveying speed of the conveying roller 111 to improve the material unloading efficiency. The conveying roller 111 at the lower / upstream section of the material conveying mechanism 11 is accelerated to rotate through the one-way clutch mechanism 113 to avoid slip friction between the material and the conveying roller 111 at the lower / upstream section of the material conveying mechanism 11, thereby reducing the service life of the conveying roller 111 at the lower / upstream section of the material conveying mechanism 11;

[0084] S23, control the furnace door mechanism 14 to be in an open state, and the push / pull mechanism 2 pushes the material on the material transfer platform 13 out of the furnace door mechanism 14. After the material is pushed out, the push / pull mechanism 2 is reset, and the furnace door mechanism 14 is controlled to be in a closed state. In this step, since the material moves by friction and sliding on the material transfer platform 13, no inertial sliding will occur, so the pushing speed can be accelerated, thereby shortening the opening time of the furnace door mechanism 14, reducing heat loss and reducing energy consumption;

[0085] Repeat steps S22-S23 to continuously discharge the kiln.
