Description

Technical Field

[0001] This invention belongs to the field of ceramic production technology, specifically a kiln for double-sided seamless firing of Jun porcelain glaze and its firing process. Background Technology

[0002] Jun ware is a traditional Chinese porcelain, first produced in the Tang Dynasty and reaching its peak in the Song Dynasty. It was a tribute porcelain for the imperial palace and enjoyed the reputation of "gold has a price, but Jun ware is priceless." Jun ware has a history of over a thousand years. Besides the composition of the clay and glaze, and the glazing techniques, the kiln structure and firing process are the main factors contributing to the distinctive appearance of Jun ware. To avoid environmental pollution caused by firing processes using firewood, coal, and gas as heating sources, ceramic researchers have been dedicated to improving and researching electric kilns for Jun ware.

[0003] The existing kiln chamber structure is mostly fixed, which makes it impossible to adjust the firing space according to the shape and height of Jun porcelain, resulting in wasted space and increased costs. In addition, due to the existence of kiln transformation, oxidation and reduction reactions need to occur at different temperature stages to make Jun porcelain exhibit colorful variegation, which conventional electric kilns cannot meet. Summary of the Invention

[0004] The purpose of this invention is to provide a kiln for double-sided seamless firing of Jun porcelain glaze and its firing process, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a kiln for double-sided seamless firing of Jun porcelain glaze, comprising an electric heating kiln-making mechanism and a control mechanism, wherein the control mechanism is fixedly installed on one side of the electric heating kiln-making mechanism.

[0006] The electric heating kiln mechanism includes an electric heating base. A heat insulation component and a heating chamber component are fixedly connected to the top of the electric heating base. The heat insulation component includes an outer heat insulation plate and an inner heat insulation plate. A heat insulation cavity is fixedly connected between the inner wall of the outer heat insulation plate and the inner wall of the inner heat insulation plate. The heating chamber component includes a central shaft. A heating chamber cover is fixedly connected to the top of the central shaft. A high-temperature electric heating chamber is fixedly connected between the bottom of the heating chamber cover and the inner wall of the inner heat insulation plate.

[0007] Multiple shelf-mounted assemblies are fixedly connected to the outer wall of the central shaft. Each shelf-mounted assembly includes a fixed shelf, with multiple counterweight grooves at the bottom of the fixed shelf. Counterweight blocks are slidably connected to the inner walls of the multiple counterweight grooves. A support plate is fixedly connected to the bottom of the fixed shelf. Multiple movable shelf panels overlap the inner wall of the fixed shelf. Multiple shaped bottom grooves are provided at the top of both the movable shelf panels and the top of the fixed shelf.

[0008] The above structure achieves the effect of adapting to various shapes and sizes of Jun porcelain blanks. The shelf layer components are adjusted according to the shape and size of the Jun porcelain blank. When the height of the Jun porcelain blank is less than the distance between two fixed shelf panels, the Jun porcelain blank can be placed in the bottom groove of the shape according to the original layout. When the height of the Jun porcelain blank is greater than the distance between two fixed shelf panels, the movable shelf panel at the top of the Jun porcelain blank can be removed to adapt to the height of the Jun porcelain blank. Then, the position of the counterweight block is adjusted in the counterweight slide to make the weight distribution on the fixed shelf panel even. The support plate is used to strengthen the stability and prevent the movable shelf panel from tilting and affecting the yield.

[0009] As a further technical solution of the present invention, the inner wall of the heat insulation cavity is fixedly connected with two sealing door slide grooves, and the inner wall of the sealing door slide grooves is slidably connected with movable sealing doors. The inner wall of the heat insulation inner layer plate and the inner wall of the two movable sealing doors are provided with multiple exhaust holes.

[0010] The above structure achieves a comprehensive constant temperature effect. Heat is discharged into the high-temperature electric heating chamber through the exhaust holes on the inner insulation plate and the movable sealing door, and the exhaust holes are evenly distributed.

[0011] As a further technical solution of the present invention, the heating chamber assembly includes four air intake nozzles, all of which are fixedly installed on the top of the electric heating base and evenly distributed around the high-temperature electric heating chamber.

[0012] The above structure serves to evenly distribute the ejected gas, which is simultaneously ejected from the air intake nozzles distributed around the perimeter.

[0013] As a further technical solution of the present invention, the top of the heat-insulating outer layer plate is fixedly connected to a furnace wall, the top of the furnace wall is fixedly connected to a semi-circular dome cover, and the top of the semi-circular dome cover is fixedly connected to a smoke exhaust duct.

[0014] The above structure serves to exhaust smoke. The insulation cavity and the semi-circular dome hood are interconnected, allowing the exhaust gas to be concentrated and discharged through the smoke exhaust duct.

[0015] As a further technical solution of the present invention, an outer door assembly is fixedly connected to the top of the electric heating base. The outer door assembly includes multiple head slides and multiple tail slides, which are distributed at the bottom of the furnace wall and the top of the electric heating base.

[0016] As a further technical solution of the present invention, a head slide rod is slidably connected to the inner wall of the head slide groove, and a tail slide rod is slidably connected to the inner wall of the tail slide groove, wherein a sliding outer door is fixedly connected between the outer walls of the two head slide rods and the outer walls of the two tail slide rods.

[0017] The above structure serves to save space and provide secondary protection. After the movable sealing door is closed, the sliding outer doors on both sides are closed.

[0018] As a further technical solution of the present invention, the control mechanism includes a control cabinet, a control console is fixedly connected to the top of the control cabinet, and multiple gas boxes are fixedly connected to the inner wall of the control console.

[0019] As a further technical solution of the present invention, the bottom of each of the gas boxes is fixedly connected with a gas supply pipe, and the gas supply pipe is fixedly connected to the electric heating base through the control cabinet.

[0020] As a further technical solution of the present invention, a flow control valve and a float flow meter are fixedly connected to the outer wall of the gas pipeline.

[0021] The above structure achieves better firing results. The gas box in the control cabinet can supply gases such as carbon monoxide and oxygen to the electric heating base through the gas supply pipe during the firing process. The gases are then sprayed out simultaneously by the air inlet nozzles distributed around the perimeter. The gas flow rate and sealing can be controlled by the flow control valve and the float flow meter, so as to comprehensively improve the gas utilization rate and coverage.

[0022] A firing process for a double-sided, seamless firing kiln for Jun porcelain glaze includes the following steps:

[0023] S1. During operation, adjust the shelf layer components according to the shape and size of the Jun porcelain blank. When the height of the Jun porcelain blank is less than the distance between the two fixed shelves, the Jun porcelain blank can be placed in the bottom groove of the shape according to the original layout. When the height of the Jun porcelain blank is greater than the distance between the two fixed shelves, the movable shelf at the top of the Jun porcelain blank can be removed to adapt to the height of the Jun porcelain blank. Then, adjust the position of the counterweight block in the counterweight slide to make the weight distribution on the fixed shelves even. The support plate is used to strengthen the stability and prevent the movable shelf from tilting and affecting the yield.

[0024] S2. After the Jun porcelain blank is placed in, the electrically controlled movable sealing door slides and closes in the sealing door groove to prevent the movable sealing door from being opened by human or accident during firing, which could cause danger. After the movable sealing door is closed, the sliding outer doors on both sides are closed. The head slide rod and tail slide rod at the top and bottom slide in the head slide groove and tail slide groove respectively and close in the heat insulation outer layer plate, which saves space and provides a second layer of protection.

[0025] S3. During firing, the electric heating base provides and raises the temperature in a timed and quantitative manner according to the heating process of Jun porcelain blanks. The heat is discharged into the high-temperature electric heating chamber through the exhaust holes on the inner insulation plate and the movable sealing door of the heat insulation cavity. Due to the even distribution of exhaust holes, a comprehensive constant temperature effect can be achieved, providing a basis for seamless firing. The gas box in the control cabinet can supply carbon monoxide, oxygen and other gases to the electric heating base through gas supply pipes during the firing process, and then spray them out simultaneously through the air inlet nozzles distributed around the perimeter. The gas flow rate and sealing can be controlled by the flow control valve and float flow meter, so as to comprehensively improve the gas utilization rate and coverage rate and achieve better firing effect. In addition, the heat insulation cavity and the semi-circular dome cover are in circulation, which can concentrate the exhaust gas and discharge it through the smoke exhaust duct.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention achieves the effect of adapting to various shapes and sizes of Jun porcelain blanks by setting a removable movable shelf on a fixed shelf. The shelf layer assembly is adjusted according to the shape and size of the Jun porcelain blank. When the height of the Jun porcelain blank is less than the distance between two fixed shelf panels, the Jun porcelain blank can be placed in the bottom groove of the shape according to the original layout. When the height of the Jun porcelain blank is greater than the distance between two fixed shelf panels, the movable shelf at the top of the Jun porcelain blank can be removed to adapt to the height of the Jun porcelain blank. Then, the position of the counterweight block is adjusted in the counterweight slide to make the weight distribution on the fixed shelf even. The support plate strengthens the stability and prevents the movable shelf from tilting, which would affect the yield.

[0028] 2. This invention uses an electric heating base to provide and raise the temperature in a timed and quantitative manner according to the heating process of Jun porcelain blanks. The heat is discharged into the high-temperature electric heating chamber through the exhaust holes on the inner insulation plate and the movable sealing door of the heat preservation cavity. Since the exhaust holes are evenly distributed, a comprehensive constant temperature effect can be achieved, providing a basis for seamless firing. The gas box in the control cabinet can provide carbon monoxide, oxygen and other gases to the electric heating base through gas pipes during the firing process, and then spray them out simultaneously through the air inlet nozzles distributed around the perimeter. The gas flow rate and sealing can be controlled by the flow control valve and the float flow meter, so that the gas utilization rate and coverage rate are comprehensively improved, and a better firing effect is achieved.
