[0002] Firing is a crucial step in making ceramic products. The firing temperature is generally between 1000 and 1200℃. Initially, people might have piled firewood on flat ground, placed the clay body on it, and lit a fire to fire it. However, this method resulted in poor quality pottery and a low yield because the heat was not concentrated enough to reach a certain temperature. Later, people invented the pottery kiln. According to archaeological excavation data, there were two main types of pottery kilns in the Neolithic Age: horizontal pit kilns and vertical pit kilns.

[0003] The existing methods for firing ceramic products mostly involve placing the ceramics to be fired on racks inside the kiln for centralized firing. The ceramics located inside the kiln require personnel to reach their arms into the kiln to retrieve them, which can easily cause them to collide with other ceramic products and fall, resulting in low safety.

[0004] Therefore, it is necessary to provide a new type of ceramic product firing kiln to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A top sectional view of a preferred embodiment of the ceramic product firing kiln provided by this utility model; Figure 2 This is a top view of the structure of this utility model; Figure 3 This is a schematic diagram of the assembly structure of the threaded rod and the support component in this utility model; Figure 4 This is a top sectional view of the kiln body in this utility model.

[0023] The ceramic firing kiln includes: a kiln body 1; a base plate 2 installed at the bottom of the kiln body 1, the base plate 2 having through holes for assisting heat flow; a threaded rod 3 rotatably installed inside the kiln body 1 via an extension shaft 10, the extension shaft 10 extending outside the kiln body 1; an adjusting ring 4 movably sleeved on the threaded rod 3, the adjusting ring 4 having a support plate 5 for supporting ceramic products, the support plate 5 having mesh holes; a support member threaded onto the threaded rod 3 for supporting the adjusting ring 4; and a handwheel 15 fixed to the extension shaft 10 for providing an operating grip point. The components, including the threaded rod 3, adjusting ring 4, support plate 5, support parts, and handwheel 15, facilitate safe material handling. Operators can rotate the handwheel 15 outside the kiln body 1 to drive the extension shaft 10 and threaded rod 3 to rotate, thereby rotating the support plate 5 and moving the ceramic products inside to the operating port 19. This eliminates the need for personnel to reach into the kiln to retrieve the ceramic products from the support plate 5, greatly improving the safety of the material handling process. At the same time, the through holes on the bottom plate 2 and the mesh on the support plate 5 assist in heat flow, helping to ensure the uniform distribution of heat inside the kiln and guaranteeing the firing quality of the ceramic products.

[0024] One side of the kiln body 1 is provided with an operating port 19 for providing a material loading and unloading channel. A clamping plate 8 is slidably installed on the outer wall of the kiln body 1. The clamping plates 8 are arranged in groups, and a blocking plate 9 for sealing the operating port 19 is clamped between the clamping plates 8. A fixing bolt 12, threadedly connected to the blocking plate 9, is threadedly installed on the clamping plate 8 to stabilize the blocking plate 9. By setting up the operating port 19, clamping plates 8, blocking plates 9, and fixing bolts 12, the effects of facilitating safe and efficient material loading and unloading, and ensuring the kiln's airtightness are achieved. The operating port 19 is for loading and unloading ceramic products. It provides a convenient passage, allowing operators to work without opening the entire kiln, improving operational efficiency and safety. The grouped clamping plates 8 are slidably installed on the outer wall of the kiln body 1, and their positions can be flexibly adjusted to accommodate blocking plates 9 of different sizes. The blocking plates 9 are clamped between the clamping plates 8, which can effectively seal the operating port 19 and prevent heat loss. The fixing bolts 12 are threadedly installed on the clamping plates 8 and threadedly connected to the blocking plates 9, which plays a role in stabilizing the blocking plates 9, ensuring the airtightness of the kiln during the firing process, helping to maintain a stable environment inside the kiln, and improving the firing quality of ceramic products.

[0025] An extension block 11 extending into the operating opening 19 is installed on the blocking plate 9. The kiln body 1 is covered with a heat-insulating pad 13 to reduce heat loss. The heat-insulating pad 13 has two Velcro fasteners 14 that can be glued together to connect the two ends of the heat-insulating pad 13. By setting up components such as the extension block 11, the heat-insulating pad 13, and the Velcro fasteners 14, the kiln's sealing performance is improved, heat loss is reduced, and installation is facilitated. The extension block 11 is installed on the blocking plate 9 and extends into the operating opening 19, further enhancing the sealing effect of the blocking plate 9 on the operating opening 19, preventing heat loss from gaps, and ensuring the temperature stability inside the kiln. The heat-insulating pad 13 covering the kiln body 1 plays a role in reducing heat loss, helping to maintain a high-temperature environment inside the kiln and improve energy utilization efficiency. The two Velcro fasteners 14 on the heat-insulating pad 13 allow the two ends of the heat-insulating pad 13 to be easily and quickly connected together, simplifying the installation process and facilitating subsequent disassembly and replacement, thus providing convenience for the maintenance and use of the kiln.

[0026] An extension plate 16 is fixed to the handwheel 15. A limiting bolt 17, which can contact the top of the kiln body 1 to stabilize the threaded rod 3, is threaded onto the extension plate 16. By setting the extension plate 16 and the limiting bolt 17, the threaded rod 3 is stabilized and the operation safety is improved. The extension plate 16 is fixed to the handwheel 15, providing an installation base for the limiting bolt 17, so that the limiting bolt 17 can be adjusted in position as the handwheel 15 rotates. When the threaded rod 3 rotates to the appropriate position and the ceramic product is picked up or put down, the limiting bolt 17 is rotated to contact the top of the kiln body 1, which can effectively limit the further rotation of the threaded rod 3, thereby stabilizing the threaded rod 3.

[0027] The support consists of a threaded cylinder 6 threaded onto the threaded rod 3 and an extension rod 7 fixed to the threaded cylinder 6 to expand the support range. The extension rod 7 contacts the bottom of the support plate 5. By setting up the support consisting of the threaded cylinder 6 and the extension rod 7, the support range is expanded and the support plate 5 is stabilized. The threaded cylinder 6 is threaded onto the threaded rod 3 and can move up and down along the path of the threaded rod 3, thereby adjusting the height of the support plate 5 and facilitating the loading and unloading of ceramic products. The extension rod 7 fixed to the threaded cylinder 6 expands the support range, allowing the support plate 5 to be placed more stably on the extension rod 7, avoiding wobbling or tilting of the support plate 5 due to an insufficient support range.

[0028] A support plate 18 is provided on the base plate 2. The extension shaft 10 is rotatably connected to the support plate 18. A connecting rod for stabilizing the support plate 18 is installed between the support plate 18 and the kiln body 1. By setting the support plate 18 and the connecting rod, the extension shaft 10 is stabilized, and the overall structure is kept stable. The support plate 18 is set on the base plate 2 and rotatably connected to the extension shaft 10, providing a reliable support foundation for the extension shaft 10. This allows the extension shaft 10 to remain stable during rotation and is not prone to shaking or displacement. At the same time, the connecting rod installed between the support plate 18 and the kiln body 1 further enhances the stability of the support plate 18, plays a reinforcing role, and prevents the support plate 18 from deforming or being damaged due to uneven force.

[0029] The kiln body 1 is provided with a guide groove, and a slider connected to the clamping plate 8 is slidably installed in the guide groove. The slider, in conjunction with the guide groove, is used to limit the movement path of the clamping plate 8. By setting the guide groove and the slider connected to the clamping plate 8, the movement path of the clamping plate 8 is limited, and the convenience and stability of operation are improved. The guide groove is opened on the kiln body 1, providing a clear sliding track for the slider. The slider is connected to the clamping plate 8, so that the clamping plate 8 can strictly follow the path set by the guide groove during movement. This design not only ensures the accuracy and stability of the movement of the clamping plate 8 and prevents it from affecting the sealing effect of the blocking plate 9 on the operating port 19 due to deviation or shaking, but also greatly simplifies the operation process of the operator and improves work efficiency.

[0030] The working principle of the ceramic product firing kiln provided by this utility model is as follows:

[0031] In use, during the firing of ceramic products, the kiln body 1 is the main firing space. When loading and unloading, first loosen the fixing bolts 12 to disconnect the connection between the blocking plate 9 and the clamping plate 8. Then, remove the blocking plate 9 along with the extension block 11 from the operating port 19. At this time, the operating port 19 opens, forming a loading and unloading channel. Place the ceramic products to be fired on the support plate 5. Afterward, snap the blocking plate 9 and extension block 11 back into place between the clamping plates 8. Secure the blocking plate 9 to the clamping plate 8 with the fixing bolts 12 to stabilize the blocking plate 9. The operating port 19 is sealed to prevent heat loss. The two ends of the insulation pad 13 are connected by Velcro 14 to further reduce heat loss and maintain a high-temperature environment inside the kiln. After firing, when it is necessary to remove the material, the operator turns the handwheel 15 outside the kiln body 1, which drives the extension shaft 10 and the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the adjusting ring 4 to move the support plate 5, moving the ceramic products inside to the operating port 19. At this time, the operator can take the ceramic products on the support plate 5 without having to put his arm into the kiln.

[0032] Compared with related technologies, the ceramic product firing kiln provided by this utility model has the following beneficial effects:

[0033] This utility model provides a ceramic product firing kiln. By setting up a threaded rod 3, an adjusting ring 4, a support plate 5, a support component and a handwheel 15, the operator can turn the handwheel 15 outside the kiln body 1 to drive the support plate 5 to move the internal ceramic products to the operation port 19 without having to reach into the kiln to retrieve them, which greatly improves the safety of the material handling process.
