Description

Technical Field

[0001] This utility model relates to the field of building material production technology, specifically to kiln components that can withstand high temperatures. Background Technology

[0002] Building materials refer to all materials used in construction projects, including natural materials such as stone and wood, synthetic materials such as cement and plastics, metallic materials such as steel, and various composite materials. Different materials have different physical, chemical, and mechanical properties, which can meet the needs of different building structures and functions.

[0003] Many building materials require high-temperature treatment during production to achieve specific properties and structures. For example, ceramic bricks need to be sintered at high temperatures to tightly bond the particles in the material and form a hard, wear-resistant surface. Therefore, kilns are used. A kiln is a device used to heat and process materials, and it usually consists of a furnace body, a combustion system, a temperature control system, etc.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. At present, most kilns still operate manually when pushing materials into the furnace. Kilns usually have a large production capacity and can meet the needs of large-scale production of building materials, so this will increase the labor intensity of production personnel; 2. During the firing process, broken materials are inevitable. However, the temperature inside the furnace is high after firing. If it is allowed to cool naturally, it will increase the production time. Moreover, even if it is cooled, there is still a certain danger in manually entering the interior for cleaning. Utility Model Content

At the same time, there is an air gap between the inner and outer layers of the furnace body, and the outer wall of the outer layer is coated with a protective layer.

[0007] More preferably, the surfaces of the firing rack and the support plate are both provided with grid-shaped through holes, and the inner wall of the firing rack is provided with several insertion slots for connecting the support plate. The bottom of the firing rack is connected to the support legs by bolts, and the lower part of the support legs is connected to the pulley by a disc spring. The bottom wall of the furnace body is provided with a sliding groove, and the pulley at the bottom of the firing rack is slidably connected in the sliding groove. One end of the outer wall of the furnace body is sloping.

[0008] More preferably, the heating elements inside the furnace body are distributed at both ends of the inner wall and the bottom wall of the furnace body, and the bottom of the firing rack is located above the heating elements on the bottom wall of the furnace body and is spaced apart from them. Heating elements are provided on opposite sides of the furnace door and the furnace body, and a temperature controller electrically connected to the heating elements is provided on the outer wall of the furnace body.

[0009] In a further preferred embodiment, the furnace door is configured with a horizontal transmission structure via a horizontal lead screw and slides and extends within the furnace body. A slot is provided on the side of the furnace body that is in contact with the furnace door, and the furnace body and the furnace door are connected by an insertion. At the same time, the furnace body is connected to the corresponding locking blocks on the outer walls of the furnace door by buckles that are rotatably connected at both ends of its outer wall.

[0010] More preferably, the pusher plate has a circular ring structure at the top and is made of ceramic fiber adsorption material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the special coatings inside and outside the kiln provide double insulation, greatly reducing the surface temperature of the kiln, minimizing heat loss, and improving energy efficiency. The inner high-temperature resistant coating prevents cracking and aging of the inner wall of the kiln at high temperatures, while the outer high-strength protective layer enhances the overall rigidity of the kiln, improves its compressive strength, and prevents deformation. Simultaneously, the multi-directionally distributed heating elements within the kiln, combined with a temperature controller, ensure uniform heat distribution. Temperature parameters can be flexibly adjusted according to different materials to achieve optimal firing results. Multiple slots on the inner wall of the firing rack allow for height adjustment of the rack plate, accommodating different specifications of firing materials and ensuring that all parts of the material are fully heated. The grid-like perforated structure promotes hot air circulation, ensuring uniform heat transfer, improving the consistency of material firing quality, and shortening firing time.

[0014] In this invention, the firing rack and furnace door are integrated into a single structure, enabling automated loading and unloading of the rack through a transmission mechanism. This eliminates the need for manual pushing, saving manpower and time. The smooth horizontal screw drive ensures the stability of the firing rack during loading and unloading. The inclined structure at the front of the furnace and the pulley assembly at the bottom of the firing rack further stabilize the rack when pushing materials. The pusher plate structure facilitates the cleaning of debris and impurities inside the furnace without requiring manual entry, reducing labor intensity. Simultaneously, the heat dissipation holes, combined with external pipes, enable rapid and uniform cooling with the aid of an external fan, shortening cooling time and allowing for waste heat recovery, further improving energy efficiency. The gate structure provides excellent heat insulation during firing and allows for precise connection when heat dissipation is needed, achieving effective heat dissipation control. These designs not only improve energy efficiency but also provide a safer working environment for operators, reducing the risk of burns. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a high-temperature resistant kiln assembly, including a kiln body 1. A horizontal lead screw 2 is rotatably connected to one end of the outer wall of the kiln body 1. The horizontal lead screw 2 is integrally connected to the outer wall of the kiln door 3 via bolts through a nut. The kiln door 3 fits into the opening of the kiln body 1. A firing rack 4 is bolted to one side of the kiln door 3 corresponding to the kiln body 1. The firing rack 4 is slidably connected to the sliding grooves at both ends of the inner wall of the kiln body 1 via sliders. Several sets of parallel rack plates 5 are inserted and connected between the firing racks 4. A heating element 6 is provided inside the kiln body 1. A push plate 7 is attached to the furnace body 1 and is located on the opposite side of the furnace door 3. The push plate 7 is slidably connected to the grooves at both ends of the inner wall of the furnace body 1 via a slider. A heat dissipation hole 8 is provided through one side of the furnace body 1. The heat dissipation hole 8 is on the same side as the push plate 7 and is located above the push plate 7. An external pipe 9 is provided on the outer wall of the furnace body 1 at the position corresponding to the heat dissipation hole 8. A filter plate 10 is threadedly connected to the inner wall of one end of the external pipe 9. A gate plate 11 is attached to the heat dissipation hole 8. A vertical screw 12 and a support rod 13 are respectively provided at both ends of the gate plate 11. The vertical screw 12 is rotatably connected to the cavity on one side of the outer wall of the furnace body 1.

[0023] In this embodiment, as Figure 1As shown, furnace body 1 consists of a ceramic inner layer and a metal outer layer. The inner wall of the inner layer of furnace body 1 is coated with a high-temperature resistant protective layer, and the outer wall of the inner layer of furnace body 1 is coated with a high-temperature resistant heat insulation layer. An air gap exists between the inner and outer layers of furnace body 1, and the outer wall of the outer layer is coated with a protective layer. The inner layer of furnace body 1 is coated with TSBL-1022 coating, which uses a high-temperature resistant inorganic silicate modified solution as the film-forming material and incorporates nano-alumina, silicon carbide, rare earth oxides, ceramic fibers, etc. It can reach 1800℃, exhibits high thermal shock resistance, strong adhesion, and strong aging resistance, thus increasing the protective layer and reducing the problem of cracking and aging of the inner wall at high temperatures. The outer wall is coated with a TSBL-1 high-temperature resistant heat insulation coating, which has a low thermal conductivity of only 0.033W / mk, providing excellent heat insulation. The heat insulation effect is significant. In addition, the air gap between the inner and outer layers forms a double heat insulation guarantee. Because the heat insulation coating itself can effectively prevent heat conduction, and the air gap, due to the low thermal conductivity of air, further blocks the transfer of heat from the inner layer to the outer layer. This double heat insulation structure not only greatly reduces the surface temperature of the furnace body 1, reduces heat loss, and improves energy utilization efficiency, but also provides a safer working environment for external operators, reducing the risk of burns caused by contact with the high-temperature furnace body 1. At the same time, the outer protective layer of the furnace body 1 is made of TSBL-911, which has high strength, further enhancing the overall rigidity of the furnace body 1. When the temperature inside the furnace body 1 rises, a certain pressure will be generated. The high-strength protective layer provided by this coating can improve the pressure resistance of the furnace body 1 and prevent the furnace body 1 from deforming.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, both the firing rack 4 and the support plate 5 have square through holes on their surfaces. Several insertion slots for connecting the support plate 5 are also provided on the inner wall of the firing rack 4. Support legs 14 are bolted to the bottom of the firing rack 4, and pulleys are connected to the bottom of the support legs 14 via disc springs. A sliding groove is provided on the inner bottom wall of the furnace body 1, and the pulleys at the bottom of the firing rack 4 are slidably connected within this groove. One end of the outer wall of the furnace body 1 is sloped. The multiple insertion slots on the inner wall of the firing rack 4 can accommodate different specifications of firing materials. The height between the support plates 5 is adjusted to ensure that all parts of the material are fully heated. Combined with a grid-like perforated structure, hot air can circulate freely around the material, contributing to uniform heat transfer and preventing localized overheating or undercooling. This not only ensures consistent firing quality but also shortens firing time and improves production efficiency. Furthermore, to enhance the overall stability of the furnace body 1 when the firing rack 4 moves in and out, its bottom has a certain height. To improve the stability of its center of gravity, and to ensure the smooth pushing of materials by the firing rack 4, the front end of the furnace body 1 adopts a sloping structure, providing a transition channel for the firing rack 4 to enter and exit. The firing rack 4 and the furnace door 3 are integrated. When the furnace door 3 is driven by the horizontal screw 2, in order to ensure that the position for loading materials on the firing rack 4 is in the same horizontal movement, a pulley assembly is installed in the support leg 14 through a disc spring. The pulley connected to the disc spring can automatically adjust its height according to the changes in the ground, ensuring that the top of the firing rack 4 remains stable in different positions. Unlike ordinary spring structures, disc springs can withstand greater pressure and load, so they can support heavier objects. When subjected to axial load, the disc spring will compress and deform, resisting the load through its own elastic restoring force. This means that it will not affect the overall structure of the firing rack 4 when adjusting its height. Combined with the slider structure at both ends of the firing rack 4 sliding in the grooves on both sides of the inner wall of the furnace body 1, it helps to maintain the overall stability of the firing rack 4.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the heating elements 6 inside the furnace body 1 are distributed at both ends of the inner wall and the bottom wall of the furnace body 1. The bottom of the firing rack 4 is located above the heating elements 6 on the bottom wall of the furnace body 1 and is spaced apart from them. Heating elements 6 are also provided on opposite sides of the furnace door 3 and the furnace body 1. At the same time, a temperature controller 15 electrically connected to the heating elements 6 is provided on the outer wall of the furnace body 1. The multi-directional distribution of the heating elements 6 can form heat sources in multiple directions. This multi-directional heating layout can ensure that the heat inside the furnace body 1 is more evenly distributed. When the firing rack 4 is located in the furnace body 1, heat from different directions can heat the material at the same time, avoiding local overheating or overcooling that may be caused by heating in one direction. Combined with the temperature controller 15 on the outer wall of the furnace body 1, the temperature inside the furnace body 1 can be monitored and controlled in real time. According to the characteristics of different materials and process requirements, the temperature parameters can be flexibly adjusted to achieve the best firing effect.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the furnace door 3 forms a horizontal transmission structure through the horizontal screw 2 and slides and extends inside the furnace body 1. A slot is opened on the side of the furnace body 1 that fits against the furnace door 3, and the furnace body 1 and the furnace door 3 are connected by an insertion. At the same time, the furnace body 1 is connected to the corresponding locking blocks 17 on the outer wall of the furnace door 3 by the buckles 16 that are rotatably connected at both ends of its outer wall. Compared with the traditional manual pushing method, the firing rack 4, which forms an integral structure with the furnace door 3, enters and exits the furnace body 1 through the transmission structure, realizing the automated operation. There is no need for manual labor to push or pull the heavy firing rack 4 into or out of the furnace body 1, which greatly saves manpower and time. Moreover, compared with manual pushing, the transmission of the horizontal screw 2 is more stable, because manual pushing may cause the firing rack 4 to shake due to uneven force, while the horizontal screw transmission 2 can provide a stable power output, so that the firing rack 4 remains stable during the process of entering and exiting the furnace body 1.

[0027] In this embodiment, as Figure 4As shown, the pusher plate 7 has a circular ring structure at its top and is made of ceramic fiber adsorption material. A semi-circular structure of the same material is bolted to the bottom of the pusher plate 7. This semi-circular structure slides within a groove on the inner bottom wall of the furnace body 1, and its length matches the depth of the groove. The grooves at both ends of the inner wall of the furnace body 1 for sliding the pusher plate 7 are non-through. By setting the pusher plate 7 structure inside the furnace body 1, after the firing process is completed, the circular ring structure at the top of the pusher plate 7 can be easily pulled using an external rod with hooks. This pulls the pusher plate 7, causing it to adhere to the bottom wall of the furnace body 1, thus pushing out debris and impurities from the furnace body 1, greatly reducing labor intensity. No manual intervention is required to clean the furnace 1. The semi-circular structure at the bottom of the push plate 7 matches the sliding groove on the inner bottom wall of the furnace body 1. During the sliding process, it can push out the debris and impurities that fall into the sliding groove, effectively cleaning these hard-to-clean areas. At the same time, the material has excellent high-temperature resistance and can remain stable in high-temperature environments. It also has adsorption properties, effectively collecting debris. The non-through sliding groove structure set on the inner wall of the furnace body 1 corresponding to the push plate 7 is designed to limit the sliding path of the push plate 7. Secondly, considering that the push plate 7 is a consumable part, it is connected to the slider in the non-through sliding groove by bolts. This connection method makes it easy to replace the push plate 7 when it is worn or damaged.

[0028] In this embodiment, as Figure 5As shown, the vertical screw 12 and support rod 13 are located in the cavity of the outer layer of the furnace body 1. The gate plate 11 is circular, with one end connected to the nut on the outer wall of the vertical screw 12 by a bolt, and the other end of the gate plate 11 slides on the support rod 13 by a slider. At the same time, the gate plate 11 forms a lifting structure through the vertical screw 12 and is inserted and connected to the inner wall of the heat dissipation hole 8 from top to bottom. After the firing process is completed, the natural cooling process usually takes a long time to reduce the internal temperature of the furnace body 1 to a safe operating temperature, resulting in an extended production cycle. Directly opening the furnace door 3 will cause a large amount of heat inside the furnace body 1 to be quickly dissipated into the surrounding environment, posing a safety risk to the operators and also causing heat loss. Through the combination of the heat dissipation hole 8 and the external pipe 9, the heat inside the furnace body 1 can be quickly discharged through the heat dissipation hole 8 and the external pipe 9 with the help of the powerful suction force provided by the external fan. Compared with natural cooling, this not only... This significantly shortens the cooling time and enables more uniform cooling. The dissipated heat can also be recovered through heat exchangers and other equipment, improving energy efficiency. The gate 11 acts as a valve, providing good insulation during firing and reducing heat loss by fitting into the inner wall of the heat dissipation hole 8. When opening is needed, the vertical screw 12 drives the gate 11 to engage with the slot in the inner wall of the heat dissipation hole 8. The smoothness of the vertical screw 12 ensures the accuracy of each engagement with the heat dissipation hole 8. The support rod 13 on the other side provides additional support and guidance for the movement of the gate 11, ensuring its smooth vertical movement. Meanwhile, the filter plate 10 on the side of the external pipe 9 prevents impurities and debris from entering the external suction equipment, protecting its normal operation. Its detachable structure facilitates cleaning.

[0029] The usage and advantages of this utility model: The high-temperature resistant kiln component operates as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, firstly, connect one end of the external pipe 9 to the external suction device through a pipe, and then connect the other end of the suction device to the waste heat recovery device through a pipe. First, separate the buckle 16 on the outer wall of the furnace body 1 from the clamp 17. Start the power supply and rotate the horizontal screw 2. Its nut, under the transmission structure, drives the furnace door 3 to move and separate from the surface of the furnace body 1. At the same time, the pulley at the bottom of the firing rack 4 slides in the groove on the bottom wall of the furnace body 1, and the sliders at both ends of the firing rack 4 slide in the corresponding grooves at both ends of the inner wall of the furnace body 1. It should be noted that the groove is a through-type structure. When the firing rack 4 moves to the maximum travel range through the transmission structure, the sliders at both ends can slide out from the through-type groove of the furnace body 1. This structure is to facilitate the subsequent cleaning of the furnace body 1. The working space is limited, and since the transmission structure of the furnace door 3 is formed by the horizontal lead screw 2, the connecting parts connected to the nut slide on the outer wall of the box where the horizontal lead screw 2 is located, which further increases the smoothness of the transmission. Therefore, during the reverse transmission process, the sliders at both ends of the firing rack 4 can be effectively and precisely connected with the corresponding sliding grooves set on the inner wall of the furnace body 1. When placing the raw materials to be fired, the firing rack 4 does not need to move to the maximum travel path. The operator can select the spacing range between the rack plates 5 according to the specifications of the raw materials to be fired. After each set of rack plates 5 is inserted and the raw materials to be fired are placed on its surface, the next set of rack plates 5 and the laying of raw materials are installed. The raw materials need to maintain a certain interval during the laying process. After the material is added, the power is turned on again, and the horizontal screw 2 rotates in the reverse direction. During the transmission process, the furnace door 3 and the firing rack 4 slide accordingly through the pulleys at their bottom. When the firing rack 4 slides from a low position to the slope, the pulleys will be subjected to the reaction force of the road surface. This force is transmitted to the disc spring. As the load increases, the disc spring begins to compress and deform, thereby adjusting the height of the pulley. Through the elastic compression and release of the disc spring, the pulley can automatically adjust its height, so that the top of the firing rack 4 can remain stable during the sliding process. Until the furnace door 3 is inserted into the outer wall of the furnace body 1, one end of the firing rack 4 will be close to the push plate 7. At the same time, the buckle 16 on the outer wall of the furnace body 1 is used again to lock the latch 17 on the outer wall of the furnace door 3, so that the operator can quickly connect the furnace door 3 and the furnace body 1. The locking mechanism further strengthens the tight connection between the furnace door 3 and the furnace body 1, maintaining stability throughout the kiln firing process. The temperature of the heating element 6 is set by an external temperature controller 15 according to the material properties and process requirements of the raw material. During firing, the multi-directional heat sources formed by the multi-directional distribution of the heating element 6 ensure a more uniform heat distribution within the furnace body 1. The grid-like perforated structure of the firing rack 4 and the rack plate 5 allows hot air to circulate fully around the material, accelerating the firing time. Furthermore, the structure of the furnace body 1 effectively prevents heat loss. Operators can observe the internal firing process through the tempered glass viewing windows on both sides of the furnace door 3. After the firing process is completed, the power is turned off.Turn on the external suction fan and start the servo motor power that drives the vertical lead screw 12. The vertical lead screw 12 rotates, which in turn drives the gate 11 to rise through the nut. The other end of the gate 11 slides on the support rod 13 through a slider. After the gate 11 is raised, the heat dissipation hole 8 is connected to the external pipe 9. With the help of the external suction fan, the heat inside the furnace body 1 is drawn away and transported to the external waste heat recovery equipment. According to the external (Honeywell-dc1020) real-time temperature display inside the furnace body 1, the operator can intuitively understand the actual internal temperature through the digital display function, which facilitates the safe opening of the furnace door 3. After door 3 is opened via the transmission structure, the upper part of the firing rack 4 is kept stable by the horizontal screw 2, while the lower part is adjusted and slid by the bottom pulleys of the support legs 14. The operator collects materials from the rack plate 5. When cleaning the inner wall of the furnace body 1, the circular ring structure at the top of the push plate 7 is easily pulled by the hooked rod. During its sliding, the ring pushes the debris falling onto the bottom wall of the furnace body 1 outwards. Simultaneously, the debris falling into the sliding groove of the pulley is also pushed out by the semi-circular structure embedded inside the push plate 7, and finally discharged from the chute opening penetrating the slope outside the furnace body 1. The operator can then clean this area.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
