Description

Technical Field

[0001] The present invention relates to the technical field of tunnel kilns, and particularly relates to a temperature-controlled firing device for ceramic production. Background Art

[0002] In the firing of a ceramic tunnel kiln, ceramic green bodies that have undergone pre-treatments such as forming and drying are placed on the kiln cars of the tunnel kiln. The kiln cars slowly move along the tunnel kiln track. The green bodies are first gradually heated in the preheating section to remove moisture, organic substances, etc. Then they enter the firing section, where under high temperature and a specific atmosphere, physical and chemical changes occur to the ceramic green bodies to achieve the required properties and colors. Finally, they are rapidly or slowly cooled in the cooling section to obtain good quality and performance. The cooled ceramic products are taken out from the kiln tail to complete the firing process.

[0003] In existing tunnel kilns, due to the thermal expansion and contraction, the kiln doors are prone to deformation, affecting the sealing effect of the kiln body. Moreover, during batch firing, the blank materials are easily damaged. Therefore, we propose a temperature-controlled firing device for ceramic production. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a temperature-controlled firing device for ceramic production, including:

[0005] A base, on the top of which a kiln body is fixedly connected. The inner cavity of the kiln body is in the shape of a quasi-tetrahedral frustum.

[0006] A gas supply mechanism, which is fixedly connected to the top of the kiln body and extends to the top of the inner cavity of the kiln body.

[0007] An exhaust smoke mechanism, which is fixedly connected to the top of the base and extends into the interior of the kiln body.

[0008] A feeding mechanism, which is fixedly connected to the top of the base and is slidably connected to the end of the kiln body.

[0009] Among them, the gas supply mechanism includes:

[0010] A gas main pipe, on the outer side of which a gas branch pipe is fixedly connected. The end of the gas branch pipe far from the gas main pipe extends to the top of the inner cavity of the kiln body, and the outer side of the gas branch pipe is fixedly connected to the inner side of the kiln body.

[0011] A number of the gas branch pipes are provided, and the gas branch pipes are linearly and evenly distributed on the surface of the gas main pipe.

[0012] A spark plug, on the outer side of which a protective cover is fixedly connected. The surface of the protective cover is fixedly connected to the end of the gas branch pipe located inside the kiln body, and the surface of the protective cover has fine slits.

[0013] The feeding mechanism transports the ceramic blank into the interior of the kiln body, closes both ends of the kiln body, starts the smoke exhaust mechanism, and the smoke exhaust mechanism drives the air flow inside the kiln body. The main gas pipe is connected to the gas, and the gas passes through the main gas pipe, gas branch pipe, and shield in sequence, and finally enters the interior of the kiln body. Subsequently, the spark plug is started, and the spark plug ignites the gas to fire the ceramic blank. The surface of the shield is provided with fine slits, which allow the gas to spray out, preventing the flame tongue from returning to the interior of the gas branch pipe and causing an explosion after ignition. While the smoke exhaust mechanism drives the air flow inside the kiln body, it also drives the burning gas to be evenly distributed inside the kiln body, firing all the ceramic blanks inside the kiln body evenly. Under the action of the fan, on the one hand, air passes through the elbow pipe and air inlet joint to provide sufficient air for gas combustion, and on the other hand, the burning flue gas is discharged through the air outlet pipe.

[0014] Further, two sets of adjusting pipes are provided at the top of the kiln body. The two sets of adjusting pipes are symmetrically arranged with the main gas pipe as the center. Each set of adjusting pipes has several. The adjusting pipes extend to the top of the inner cavity of the kiln body, and the outer side of the adjusting pipe is fixedly connected to the inner side of the kiln body. The adjusting pipe is connected to oxygen. During the firing process, the atmosphere inside the kiln body is adjusted. In the initial stage of firing, there is sufficient oxygen in the kiln body to fully oxidize the organic matter, sulfide, etc. in the blank. The ceramics fired in an oxidizing atmosphere show bright colors. In the reducing flame stage, the oxygen content in the kiln is reduced to form a reducing atmosphere inside the kiln. In a reducing atmosphere, some metal oxides will be reduced to low valence states, thereby making the ceramics show unique colors and textures.

[0015] Further, the smoke exhaust mechanism includes a placement table fixedly connected to the top of the base, and a fan is fixedly connected to the top of the placement table. The output end of the fan is fixedly connected to an elbow pipe, and the elbow pipe extends to the side of the kiln body. The end of the elbow pipe away from the fan is fixedly connected to an air inlet joint, and the air inlet joint extends to the inner side of the cavity of the kiln body, and the outer side of the air inlet joint is fixedly connected to the inner side of the kiln body. When the fan is started, the output end of the fan outputs air, and the air passes through the elbow pipe and air inlet joint in sequence and finally enters the interior of the kiln body to provide air for firing the porcelain blank.

[0016] Further, an air outlet joint is provided directly below the air inlet joint, and the air outlet joint extends to the inner side of the cavity of the kiln body, and the outer side of the air outlet joint is fixedly connected to the inner side of the kiln body. The side of the air outlet joint away from the kiln body is fixedly connected to an air outlet pipe. The air passes through the elbow pipe, air inlet joint, kiln body, air outlet joint, and air outlet pipe in sequence, and the air forms a cycle inside the kiln body, enabling the air and fuel to be evenly distributed inside the kiln body, allowing the fuel to burn evenly, ensuring the even firing of the blank, and obtaining a better firing effect.

[0017] Furthermore, the feeding mechanism includes a frame body fixedly connected to the top of the base. The air inlet joint and the air outlet joint are embedded inside the frame body, and the inner side surface of the frame body is fixedly connected to the outer side surfaces of the air inlet joint and the air outlet joint. Both ends of the kiln body are provided with chutes, and the inner side surfaces of the chutes are slidably connected to kiln doors. Both ends of the two kiln doors are provided with electric guide rails, and the ends of the electric guide rails are fixedly connected to the bottom of the inner side surfaces of the chutes. The output ends of the electric guide rails are fixedly connected to the surfaces of the kiln doors, and the electric guide rails are fixedly connected to the frame body. When the electric guide rails are started, the electric guide rails drive the kiln doors to lift and lower, completing the opening and closing of the kiln body.

[0018] Furthermore, the inner side surface of the kiln door is fixedly connected with hexagonal tubes, and several hexagonal tubes are provided. The several hexagonal tubes are evenly distributed inside the kiln door, and the several hexagonal tubes form a honeycomb structure. The hollow kiln door can reduce the load on the electric guide rails and reduce consumption. The hexagonal tubes forming the honeycomb structure can bear pressure evenly, avoid deformation of the kiln door during firing, and ensure the sealing effect of the kiln door.

[0019] Furthermore, an inner rail is arranged inside the kiln body, and the inner rail is fixedly connected to the bottom of the inner side surface of the kiln body. Outer rails are symmetrically arranged at both ends of the inner rail, and the outer rails are fixedly connected to the top of the inner side surface of the base. A placement component is also arranged inside the kiln body, and the placement component is in rolling connection with the tops of the inner rail and the outer rails. The placement component passes through the outer rail and the inner rail on one side in sequence, and after firing is completed, it leaves the kiln body through the outer rail and the inner rail on the other side.

[0020] Furthermore, the placement component includes a kiln car. The bottom of the kiln car is in rolling connection with the tops of the inner rail and the outer rails. Columns are fixedly connected to the top of the kiln car, and four columns are arranged at the four corners of the kiln car. A partition board is arranged on the top of the kiln car, and several partition boards are provided. The surfaces of the several partition boards are fixedly connected to the four corners of the columns. The several partition boards are used for placing porcelain blanks, and the kiln car moves on the outer rail and the inner rail.

[0021] Furthermore, buffer plates are arranged at both ends of the kiln car. A sliding column is fixedly connected to the side of the buffer plate close to the kiln car, and the sliding column is slidably connected to the inner side surface of the kiln car. A spring is fixedly connected to the end of the sliding column away from the buffer plate, and the end of the spring away from the sliding column is fixedly connected to the inner side surface of the kiln car. During batch firing, multiple kiln cars enter the inside of the kiln body. The kiln cars collide with each other, the buffer plates are squeezed, driving the sliding columns to move, and the springs are compressed, thereby playing a buffering role, avoiding the offset of the blanks on the kiln car and preventing damage to the blanks.

[0022] Further, annular grooves are formed on the surface of the sliding column. A plurality of the annular grooves are formed, and the annular grooves are inclined, and the annular grooves are inclined away from the spring. When the sliding column resets, the inclined annular grooves play a hindering effect, causing the kiln cars to slowly move away from each other, and avoiding damage to the blank during resetting again. Moreover, the inclined annular grooves will not hinder the sliding column during buffering.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. By providing a firing device in the present invention, slit openings are formed on the surface of the protective cover. The slit openings enable the gas to be ejected, avoiding the explosion caused by the flame tongue returning to the inside of the gas branch pipe after ignition. While the smoke exhaust mechanism drives the air flow inside the kiln body, it drives the burning gas to be evenly distributed inside the kiln body, uniformly firing all the ceramic blanks inside the kiln body. Under the action of the fan, on the one hand, air provides sufficient air for gas combustion through the elbow pipe and the air inlet joint, and on the other hand, the burning flue gas is discharged through the air outlet pipe.

[0025] 2. By providing a kiln door in the present invention, the hollow kiln door can reduce the load on the electric guide rail and reduce consumption. Moreover, the hexagonal pipes forming a honeycomb structure can evenly bear pressure, avoid deformation of the kiln door during firing, and ensure the sealing effect of the kiln door.

[0026] 3. By providing a smoke exhaust mechanism in the present invention, air sequentially passes through the elbow pipe, the air inlet joint, the kiln body, the air outlet joint, and the air outlet pipe, providing air for the firing of the porcelain blank. At the same time, the air forms a circulation inside the kiln body, enabling the air and the fuel to be evenly distributed inside the kiln body, enabling the fuel to burn evenly, ensuring uniform firing of the blank, and obtaining a better firing effect.

[0027] 4. By providing a placement component in the present invention, when multiple kiln cars enter the inside of the kiln body, the kiln cars collide with each other. The buffer plate is squeezed, driving the sliding column to move, and the spring is compressed, thereby playing a buffering role, avoiding the offset of the blank on the kiln car and avoiding damage to the blank. When the sliding column resets, the inclined annular grooves play a hindering effect, causing the kiln cars to slowly move away from each other, and avoiding damage to the blank during resetting again. Moreover, the inclined annular grooves will not hinder the sliding column during buffering. Description of the Drawings
