Description

TECHNICAL FIELD

[0001] The present application relates to the field of porcelain firing, in particular to a kiln for firing bluish white porcelain. BACKGROUND

[0002] In the process of ceramic firing, a kiln is needed to heat and bake the ceramic. The heating is performed by the heating module arranged on the wall of the kiln. However, since the heating module is located at the outer circle of the firing area, the heat in the furnace body is not uniform. Even the different areas on the same porcelain body are not uniformly heated during firing, which has a great impact on the firing of porcelain, especially bluish white porcelain, which has higher requirements for temperature uniformity. In view of this phenomenon, a rotary frame is currently used in the kiln to rotate in the kiln, thereby reducing the phenomenon of uneven heating of the porcelain body. However, in this way, the porcelain body revolves around the shaft, and the heating surface is still relatively fixed, so there is still a certain defect. In view of the problem of uneven heating of a single porcelain body during firing, the present application is proposed. CONTENT OF THE UTILITY MODEL

[0003] The embodiments of the present application provide a kiln for firing bluish white porcelain, which can uniformly heat each part of the porcelain body and ensure that high-quality bluish white porcelain is fired.

[0004] To solve the above technical problem, the embodiments of the present application disclose the following technical scheme:

[0005] A kiln for firing bluish white porcelain comprises:

[0006] A furnace body for providing a firing environment;

[0007] A plurality of groups of firing carriers are arranged in a circular array in the furnace body, and each group of firing carriers vertically comprises at least one group of firing brackets. A plurality of groups of rotary assemblies are arranged on the firing bracket, and the rotary assemblies are sequentially driven. Each rotary assembly is provided with a tray for supporting the porcelain body to be fired.

[0008] A rotary drive mechanism is arranged at the center of the array of the plurality of groups of firing carriers, and the rotary drive mechanism drives the rotary assemblies on the firing bracket to rotate on the firing bracket.

[0009] In some embodiments, the rotary assembly comprises a rotary wheel and a rotary shaft, the firing bracket comprises a support seat, a plurality of rotary shafts are arranged on the support seat in the radial direction of the array, and a rotary wheel is arranged on the rotary shaft. The rotary wheel rotates on the support seat by the rotary shaft.

[0010] In some embodiments, the rotary shaft rotates circumferentially and is fixed axially on the support seat, and the rotary wheel is an external gear.

[0011] In some embodiments, the tray is disposed at one end of the rotary shaft and above the support base, and the tray is detachably disposed from the rotary shaft.

[0012] In some embodiments, any two adjacent sets of the rotary wheels mesh with each other and drive each other in the distribution direction of the plurality of rotary wheels.

[0013] In some embodiments, the rotary drive mechanism includes a drive shaft rotatably mounted on the furnace body, and each of the firing brackets is provided with a drive wheel on the shaft, the drive wheel being driven by the rotary assembly.

[0014] In some embodiments, a gas circulation mechanism is also included outside the furnace body, through which gas inside the furnace body is extracted and recirculated back into the furnace body.

[0015] In some embodiments, the gas circulation mechanism includes a gas pipeline and a gas pump disposed on the gas pipeline. One end of the gas pipeline is connected to the outer ring area of ​​the furnace body, and the other end is connected to the open end of the top of the drive shaft. The drive shaft has an axially oriented gas passage, and the shaft wall of the drive shaft has a plurality of gas outlet holes that are connected to and pass through the gas passage.

[0016] In some embodiments, a plurality of heating modules are provided in the inner cavity of the furnace body, and the plurality of heating modules are located between the firing carrier and the cavity wall of the furnace body.

[0017] In some embodiments, the firing support also includes a vertical frame, and a plurality of the firing supports are arranged vertically at intervals on the vertical frame, and the distance between two adjacent sets of firing supports is not less than the height of the porcelain blank to be fired.

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] In this technical solution, several sets of firing carriers are arranged in a circumferential array inside the furnace body. Several sets of rotating components are arranged on the firing carriers, and the rotating components are sequentially driven. The rotating drive mechanism drives the rotating components on the firing carriers to rotate on the firing carriers, so that the porcelain blanks are heated evenly in all areas during the firing process, thereby obtaining celadon with higher morphology and quality.

[0020] By means of a gas circulation mechanism located outside the furnace body, the gas inside the furnace body is extracted and recirculated back into the furnace body. This avoids uneven heat distribution within the kiln and reduces the phenomena of localized temperature concentration and insufficient localized temperature.

[0021] One end of the gas pipeline is connected to the outer ring area of ​​the furnace body, and the other end is connected to the open end of the top of the drive shaft. The drive shaft has an axially oriented gas passage, and several gas outlet holes are formed on the shaft wall of the drive shaft, which are connected to the gas passage. The heat from the outer area is returned to the inner area through the gas circulation structure, reducing the temperature difference in the furnace area and enabling the appropriate temperature airflow to be directly distributed to the area where each ceramic blank is located, ensuring uniform temperature.

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As attached Figure 1 and attached Figure 3 As shown, a kiln for firing celadon porcelain includes:

[0030] Furnace body 1 is used to provide a firing environment, such as heating to the temperature required to fire the corresponding porcelain;

[0031] A firing carrier 2, several sets of the firing carrier 2 are arranged in a circular array inside the furnace body 1. The firing carrier 2 includes at least one set of firing support 3 in the vertical direction. Several sets of rotating components 4 are provided on the firing support 3, and several sets of rotating components 4 are sequentially driven. Each rotating component 4 is provided with a tray 6 for supporting the porcelain blank to be fired.

[0032] A rotary drive mechanism 5 is set at the center of a circular array of several sets of firing carriers 2, and the rotary drive mechanism 5 drives the rotary components 4 on the firing brackets 3 to rotate on the firing brackets 3.

[0033] Several sets of firing carriers are arranged in a circumferential array inside the furnace. Several sets of rotating components are arranged on the firing carriers, and the rotating components are sequentially driven. The rotating drive mechanism drives the rotating components on the firing carriers to rotate on the firing carriers, so that the porcelain blanks are heated evenly in all areas during the firing process, thereby obtaining celadon with higher morphology and quality.

[0034] In some implementations, as shown in the appendix Figure 2 and attached Figure 4 As shown, the rotating assembly 4 includes a rotating wheel 8 and a rotating shaft 9. The firing bracket 3 includes a support base 7, on which a plurality of rotating shafts 9 are arranged radially along an array. The rotating wheels 8 are mounted on the rotating shafts 9, and the rotating wheels 8 rotate on the support base 7 via the rotating shafts 9. The support base 7 is a long plate structure, arranged radially along the circumferential array of the firing carrier 2. Multiple sets of rotating assemblies can be mounted on the support base 7. The transmission method using the rotating wheels 8 simplifies the structure, increases transmission efficiency, and allows for different transmission ratios. The transmission wheels and rotating shafts are made of high-temperature resistant materials, such as metal or ceramic, which improves their service life.

[0035] In some embodiments, the rotating shaft 9 rotates circumferentially and is axially fixed on the support base 7, and the rotating wheel 8 is an external meshing gear. In the distribution direction of the plurality of rotating wheels 8, any two adjacent sets of rotating wheels 8 mesh with each other for transmission. The meshing transmission of the plurality of sets of external meshing gears enables the transmission of power from the central region of the array to the outer edge region of the array.

[0036] In some embodiments, the tray 6 is disposed at one end of the rotating shaft 9 and located above the support base 7, and the tray 6 and the rotating shaft 9 are detachably connected. The tray 6 and the rotating shaft 9 can be disassembled or connected by means of threads, raised grooves, splines, snaps, etc. The detachable design of the tray 6 allows for the replacement of trays of different sizes according to the actual size of the porcelain blank being fired.

[0037] In some implementations, for exampleFigures 1-4 In this embodiment, the diameter of the tray 6 is larger than the outer diameter of the rotary wheel 8 but smaller than the maximum outer diameter of the two rotary wheels. Therefore, a tray can be set every other rotary component 4, which can provide greater versatility.

[0038] As shown in Appendix 4, in this embodiment, the outside of the rotary shaft 9 is provided with a positioning protrusion 13, the tray 6 has a T-shaped structure, and the bottom of the tray 6 includes a mounting sleeve for fitting onto the top of the rotary shaft 9. Therefore, the inner wall of the mounting sleeve is recessed with a groove matching the positioning protrusion 13, and the positioning protrusion 13 makes the tray 6 and the rotary shaft 9 circumferentially fixed.

[0039] In some embodiments, the rotary drive mechanism 5 includes a drive shaft 51, which is rotatably mounted on the furnace body. Each of the firing brackets 3 has a drive wheel 10 on its shaft, and the drive wheel 10 is driven by the rotary assembly 4. The drive wheel 10 is an external meshing gear used to mesh with the rotary wheel 8 in the rotary assembly 4. The rotary drive mechanism 5 includes a drive motor 52 and a transmission belt 53, which is a gear transmission belt that drives the output shaft of the drive motor 52 and the drive wheel 10.

[0040] In some embodiments, a gas circulation mechanism is also included outside the furnace body 1, through which gas inside the furnace body 1 is extracted and returned to the furnace body 1.

[0041] In some embodiments, the gas circulation mechanism includes a gas pipeline 22 and a gas pump 21 disposed on the gas pipeline. One end of the gas pipeline 22 is connected to the outer ring area of ​​the furnace body 1, and the other end is connected to the open end of the top of the drive shaft 21. The drive shaft 51 has an axially oriented gas passage 11, and a plurality of gas outlet holes 54 are provided on the shaft wall of the drive shaft 51 that are connected to the gas passage 51.

[0042] Through a gas circulation mechanism located outside the furnace body, the gas inside the furnace body 1 is extracted and recirculated back into the furnace body. This avoids uneven heat distribution within the kiln and reduces localized temperature concentrations and insufficient temperatures.

[0043] One end of the gas pipeline 22 is connected to the outer ring area of ​​the furnace body 1, and the other end is connected to the opening at the top of the drive shaft 51. The drive shaft 51 has an axially oriented gas passage 11, and several gas outlet holes 54 are formed on the shaft wall of the drive shaft 51, which are connected to the gas passage 11. The heat from the outer area is returned to the inner area through the gas circulation structure, reducing the temperature difference in the furnace area and enabling the appropriate temperature airflow to be directly distributed to the area where each ceramic blank is located, ensuring uniform temperature.

[0044] In some embodiments, a plurality of heating modules are provided in the inner cavity of the furnace body 1, and the plurality of heating modules are located between the firing carrier 2 and the cavity wall of the furnace body 1.

[0045] In some embodiments, the firing support 2 further includes a vertical frame 12, on which a plurality of firing brackets 3 are vertically spaced, and the distance between two adjacent sets of firing brackets 3 is not less than the height of the porcelain blank to be fired. The vertical frame is used to support the plurality of firing brackets 3.

[0046] In some embodiments, the firing bracket 3 can also be height-adjusted on the stand 12 to adjust the distance between two adjacent sets of firing brackets, allowing for the installation of more firing brackets or the removal of some firing brackets.
