Description

Technical Field

[0001] This invention relates to the field of preparation technology, specifically to a method for preparing a crack-cracked rapid firing gold metallic glaze. Background Technology

[0002] The glaze of porcelain is covered with many small cracks, some sparse, some dense, some coarse, some fine, some long, some short, some curved, some straight, resembling the cracks of a tortoise, crab claws, or ice. This is called crackle glaze. Originally a defect in the porcelain-making process, crackle glaze was later used to decorate porcelain. Ge ware is famous for this feature. The crackle patterns are interwoven into many fine eye-like patterns, called fish roe patterns. The denser and more fragmented patterns are called hundred-crack patterns. Before firing crackle glaze, various coloring metal oxides, such as Fe, Cr, Mn, Co, Cu, or rare earth oxides, such as argon oxide, titanium oxide, and ceramic colorants such as yellow ochre and lilac purple, can be added to it and mixed to obtain the desired glaze color. When it is necessary to make a gold metallic glaze with a golden glaze color, gold oxide is added to the crackle glaze and it is fired in a kiln. The preparation method of making this crackle glaze with a golden glaze color can be called a method of preparing crackle-fired gold metallic glaze.

[0003] Existing kilns primarily cool aluminum titanate through heat conduction to the kiln walls, followed by air convection. This natural cooling process has drawbacks, including excessively long cooling times, resulting in poor cooling efficiency and uneven cooling. Patent CN116793094A, titled "A Kiln with Controllable Cooling Environment," addresses these issues by employing a combination of a water storage tank, a heat dissipation shell, a heat dissipation cylinder, cooling components, a drive component, an accelerated cooling component, and a circulation component. When cooling is required, the drive component activates, rotating and agitating the water in the heat dissipation cylinder. The accelerated cooling component further enhances the cooling effect, and the circulation component circulates the water between the accelerated cooling component and the water storage tank, achieving rapid cooling and significantly improving efficiency. This solution addresses the aforementioned problems.

[0004] However, the kiln used in this preparation method has limitations: the firing fire source has a small coverage area, which cannot completely cover the glaze inside, resulting in low firing efficiency. Furthermore, the equipment generates a large amount of soot, which requires filtering. Due to the large volume of soot, the filter needs to be opened frequently for cleaning, a cumbersome process. Therefore, this method does not meet current requirements. To address this, we propose a method for rapidly firing gold metallic glaze using cracking techniques. Summary of the Invention

[0005] The purpose of this invention is to provide a method for preparing a crack-fired gold metallic glaze, in order to solve the problems mentioned in the background art, such as the small coverage area of ​​the firing fire source in the kiln used in this preparation method, which cannot completely cover the glaze inside, resulting in low firing efficiency, and the generation of a large amount of soot when using this equipment.

[0020] Preferably, the upper surface of the vibration frame facing the dust collection box is an inclined surface, and a spring connects the vibration frame to the heat insulation shell.

[0021] A method for preparing a crack-cracked, rapidly fired gold metallic glaze, comprising the following steps:

[0022] Step A: Place the crackled glaze containing gold metal oxides into the glaze rack and plate, then push it into the kiln chamber. Close the kiln door, start the kiln, and spray flames through the nozzle. The flames sprayed through the nozzle will act on the arc-shaped surface at the lower end of the flame diffuser plate through the oblique flame guide. Because the arc-shaped surface is arc-shaped, the flames will spread on its bottom surface. The spread flames will be sprayed out through the flame diffuser at the upper end of the flame diffuser plate.

[0023] Step B: The hot air generated by the fire source will enter the interior of the hot air guide pipe located on the inner wall of the upper end of the firing chamber, and then enter the interior of the air guide pipe connected to it. The hot air entering the air guide pipe will be discharged through multiple air outlets located on both sides of the outer surface of the air guide pipe, and act on the cracked glaze located on the outer surface of the glaze placement rack and glaze placement plate. The fire source located inside the inclined flame guide port will enter the interior of the fire source hot air transmission groove connected to it through the inclined flame guide port, and then enter the interior of the positioning air transmission pipe along the fire source hot air transmission groove, and then enter the interior of the air outlet connected to it at this time through the positioning air transmission pipe.

[0024] Step C; The smoke generated during the firing process will enter the interior of the soot outlet and be filtered by the soot filter screen located inside the soot outlet. After being discharged, after the equipment finishes its daily work, the stepper motor is started. The stepper motor drives the motor drive shaft connected to it to rotate. When the motor drive shaft rotates, the first bevel gear fixedly sleeved on the lower side of the outer surface of the motor drive shaft will also rotate. When the first bevel gear rotates, the two second bevel gears meshing with it will also rotate. When the second bevel gears rotate, the short rotor located on its axis... The shaft and the metal column fixed to the short rotating shaft will also rotate. When the metal column rotates, the moving rod that is slidably installed in the wavy groove on the outer surface of the metal column will move left and right along the wavy groove. During the movement of the moving rod, the movable sleeve fixed to it will also move. During the movement of the movable sleeve, the square plate connected to it by the push rod will also move. When the square plate moves towards the ash filter, the unblocking rod on its outer surface will pass through the filter hole on the outer surface of the unblocking rod and unblock the impurities inside.

[0025] Step D: During the rotation of the motor drive shaft, the fourth bevel gear mounted on the upper surface of the motor drive shaft will also rotate. When the fourth bevel gear rotates, the two third bevel gears meshing with it and the drive shaft connected to the shaft center of the fourth bevel gear will also rotate. When the drive shaft rotates, the double concave rod fixed to it will also rotate. When the double concave rod rotates, the metal sleeve fitted on the concave part of the outer surface of the double concave rod will rotate with it and revolve around the drive shaft. During the rotation of the metal sleeve, it will drive the fixed part... The lever moves up and down, which in turn moves the vibrating frame fixed to its bottom surface up and down. During this movement, the vibrating frame compresses the spring and generates vibration. Through this vibration and the inclined surface on its upper end, the ejected impurities move towards the dust collection box located in the center of the vibrating frame and fall into the dust collection box. After a period of time, the dust collection box is removed and the impurities inside are emptied. Once the impurities inside are cleaned, the dust collection box is reinstalled on the lower end of the vibrating frame.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The present invention utilizes a flame source ejected from the flame outlet to act on the arc-shaped surface of the lower end face of the flame diffuser plate and diffuse it. The flame source diffused by the arc-shaped surface will be ejected through multiple flame diffuser ports located on the upper end face of the flame diffuser plate. Through the above technical solution, the flame source ejected from the flame outlet can be dispersed into multiple streams, thereby increasing the coverage of the flame source. In this process, the hot gas entering the hot gas guide pipe will be released through the gas outlet located on the outer surface of the gas guide pipe at the middle position between the two glaze placement plates and the upper end face of the glaze placement rack, so that it acts on the side of the glaze that cannot be directly baked by the flame. Through the above technical solution, the firing efficiency of the equipment is improved.

[0028] 2. After each day's work is completed, the present invention uses an automatic ash collection mechanism to collect the impurities adhering to the ash filter into the dust collection box, eliminating the need for frequent manual cleaning of the ash filter. This technical solution improves the convenience of the equipment. Attached Figure Description
