Description

Technical Field

[0001] The present invention relates to the technical field of ceramic glaze preparation, and particularly relates to a method for preparing a ceramic glaze with stable quality. Background Art

[0002] Powdery ceramic glaze raw materials (hereinafter referred to as powdery raw materials) are the key raw materials for making ceramic glazes, and their fineness has a crucial impact on the performance of ceramic glazes. Generally speaking, the finer the powdery raw materials, the better the plasticity, and the better the adhesion and smoothness during subsequent firing. After screening, agents need to be added and stirred. At present, the stirring of powdery raw materials generally adopts the method of manual hand-held electric stirring equipment, and workers also need to add agents for stirring according to strict ratios and continuously stir for more than half an hour. The labor intensity is high, the work is boring, the labor cost is high, and when workers configure and add agents, misconfiguration and omission often occur, resulting in unstable quality of the manufactured ceramic glaze. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for preparing a ceramic glaze with stable quality, which screens and accurately proportionally stirs powdery raw materials, and the quality of the manufactured ceramic glaze is stable.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions: A method for preparing a ceramic glaze with stable quality, the specific steps are as follows: Step 1: Select the raw material components for preparing the ceramic glaze. The raw material components include 20 - 22 parts by weight of quartz, 15 - 16.5 parts by weight of clay, 30 - 35 parts by weight of feldspar, and 10 - 11 parts by weight of bauxite. The raw material components are broken into granular raw materials with a diameter less than 2 cm; Step 2: Dry the granular raw materials; Step 3: Fine-grind the dried granular raw materials into powdery raw materials with a diameter less than 13 μm through a ball mill; Step 4: Use a processing device to screen the powdery raw materials, remove the powdery raw materials with a diameter greater than 13 μm therein, and then add a flux and stir to mix to form a ceramic glaze; Among them, the processing device includes an aggregate box, a controller, and a quantitative pumping device and a liquid storage bucket containing a flux arranged outside the aggregate box. The aggregate box is detachably provided with an aggregate box. The liquid storage bucket pumps the flux into the aggregate box through the quantitative pumping device. A weighing device for weighing the aggregate box is arranged at the bottom of the aggregate box inside the aggregate box; a separation chamber is provided at the top of the aggregate box, a top cover is detachably covered on the top of the separation chamber, a feeding hopper communicating with the separation chamber is provided on the top of the top cover, and a solenoid valve is arranged at the discharge port of the feeding hopper; the powdery raw materials obtained in Step 3 are loaded into the feeding hopper; Inside the separation chamber, a screening component for screening powdery raw materials is provided. The screening component includes a 1000-mesh sieve. An outer frame is fixedly provided at the outer end of the sieve. A vibration motor is provided at the outer end of the outer frame. More than three springs are fixedly provided at equal intervals at the outer end of the outer frame. One end of the spring is connected to the inner wall of the separation chamber. An elastic rubber ring is fixedly provided at the top end of the outer frame. The elastic rubber ring is funnel-shaped. An installation ring is fixedly provided at the top end of the elastic rubber ring. The installation ring is provided on the inner wall of the separation chamber. A partition is fixedly provided on the inner wall of the separation chamber. The partition is provided at the bottom of the screening component. The upper plane of the partition is inclined into a funnel. The bottom end of the funnel of the partition communicates with a delivery pipe directly above the aggregate box. The delivery pipe does not contact the aggregate box. After the solenoid valve is opened, the powdery raw materials fall onto the screening component. The vibration motor is turned on to vibrate the screening component, screening the powdery raw materials with a diameter less than 13 μm into the partition, and the partition drops the materials into the aggregate box through the delivery pipe. One or more electric lifting and stirring mechanisms are further provided at the bottom of the partition, and the electric lifting and stirring mechanisms do not contact the delivery pipe. The solenoid valve, the metering pumping device, the weighing device, the vibration motor, and the electric lifting and stirring mechanism are respectively electrically connected to the controller. When the weight of the powdery raw materials falling into the aggregate box measured by the weighing device reaches the preset weight value, the controller controls the solenoid valve to close, the vibration motor to stop vibrating, the metering pumping device to start pumping flux into the aggregate box, and at the same time the electric lifting and stirring mechanism descends to stir the powdery raw materials and the flux evenly to form ceramic glaze. After the stirring is completed, the controller controls the electric lifting and stirring mechanism to rise above the aggregate box.

[0005] Further, after the granular raw materials are dried in the second step, the moisture content of the granular raw materials is less than or equal to 0.5%.

[0006] Further, in the fourth step, the moisture content of the prepared ceramic glaze is 18%-22%.

[0007] Further, a transparent observation window for observing the inside of the aggregate box is provided on the aggregate box.

[0008] Further, a dust suction pipe and a ventilation hole are also provided through the top cover. The dust suction pipe extends into the separation chamber. A dust suction device is further included. The dust suction device is electrically connected to the controller. When it is necessary to clean the powdery raw materials that have not fallen through the sieve, the controller controls the vibration motor to vibrate, and the dust suction device is turned on to suck out the powdery raw materials that have not fallen through the sieve on the sieve from the dust suction pipe.

[0009] In the above technical solution, the technical effects and advantages provided by the present invention are: This pairs the screening of powdery raw materials and precise proportioning and stirring, resulting in stable quality of the ceramic glaze. Specifically, during use, the weighing weight of the powdery raw materials and the corresponding amount of pumped flux can be preset in the controller. When the solenoid valve is opened, the powdery raw materials fall onto the screening component, and the vibration motor is turned on to make the screening component vibrate. The powdery raw materials with a diameter less than 13 μm are screened into the partition board and fall into the aggregate box through the conveying pipe by the partition board. When the weighing device weighs the powdery raw materials falling into the aggregate box and reaches the preset weight value, the controller controls the solenoid valve to close, the vibration motor stops vibrating, and the quantitative pumping device is turned on to pump flux into the aggregate box. At the same time, the electric lifting and stirring mechanism descends to stir the powdery raw materials and the flux evenly, forming the ceramic glaze. The obtained ceramic glaze has stable quality, the powdery raw materials have a small fineness and good plasticity, and the adhesion and smoothness are good during subsequent firing.

[0017] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the drawings.

[0018] Reference Figures 1-5 , this embodiment provides a method for preparing a ceramic glaze with stable quality, and the specific steps are as follows: Step 1: Select the raw material components for preparing the ceramic glaze. The raw material components include 20-22 parts by weight of quartz, 15-16.5 parts by weight of clay, 30-35 parts by weight of feldspar, and 10-11 parts by weight of bauxite. The raw material components are broken into granular raw materials with a diameter less than 2 cm.

[0019] Specifically, in this specific embodiment, preferably, the raw material components include 20 parts by weight of quartz, 16 parts by weight of clay, 33 parts by weight of feldspar, and 10 parts by weight of bauxite. The above raw material components are the basic components for preparing the ceramic glaze. Appropriate amounts of cobalt oxide, iron oxide, copper oxide, and manganese oxide can also be added according to the need to present the color of the ceramic glaze, giving rich colors to the prepared ceramic glaze.

[0020] Step 2: Dry the granular raw materials. In this specific embodiment, the moisture content of the dried granular raw materials is less than or equal to 0.5%. The lower the moisture content of the granular raw materials, the less likely the powdered raw materials obtained by fine grinding with a ball mill are to adhere, and the easier they are to screen. Of course, the lower the moisture content, the higher the energy consumption required for drying. Preferably, in this specific embodiment, the moisture content of the dried granular raw materials is 0.5%.

[0021] Step 3: Fine grind the dried granular raw materials into powdered raw materials with a diameter less than 13 μm by a ball mill. Of course, the diameter of the powdered raw materials after fine grinding by the ball mill can also be selected according to the need. The finer the powdered raw materials, the better.

[0022] Step 4: Use a processing device to screen the powdered raw materials, remove the powdered raw materials with a diameter greater than 13 μm, and then add a fluxing agent and stir and mix to make a ceramic glaze.

[0023] The fluxing agent component includes any one or a combination of sodium oxide, potassium oxide, lead oxide, and boron oxide.

[0024] Among them, the processing device includes an aggregate bin 1, a controller, a dust collection device (the controller and the dust collection device are not shown in the figure, and it should be noted that the installation positions of the controller and the dust collection device do not affect their use), a quantitative pumping device 31 arranged outside the aggregate bin 1, and a liquid storage bucket 3 containing flux. A detachable aggregate box 4 is arranged on the aggregate bin 1. The liquid storage bucket 3 pumps flux into the aggregate box 4 through the quantitative pumping device 31. A weighing device 15 for weighing the aggregate box 4 is arranged at the bottom of the aggregate box 4 inside the aggregate bin 1; a separation chamber 5 is provided at the top of the aggregate bin 1. A top cover 6 is detachably covered on the top of the separation chamber 5. A feeding hopper 7 communicating with the separation chamber 5 is provided on the top of the top cover 6. A solenoid valve is arranged at the discharge port of the feeding hopper 7; the powdered raw material prepared in step three is loaded into the feeding hopper 7; when the solenoid valve is opened, the powdered raw material in the feeding hopper 7 falls into the separation chamber 5.

[0025] A dust collection pipe 2 and a ventilation hole 11 also penetrate through the top cover 6. The dust collection pipe 2 extends into the interior of the separation chamber 5. The purpose of setting the ventilation hole 11 is to balance the air pressure inside the separation chamber 5 with the atmospheric pressure. A one-way valve that can only ventilate into the separation chamber 5 can also be set on the ventilation hole 11 as needed.

[0026] A screening assembly 8 for screening powdered raw materials is arranged inside the separation chamber 5. The screening assembly 8 includes a 1000-mesh screen 801. An outer frame 802 is fixedly arranged at the outer end of the screen 801. A vibration motor 804 is arranged at the outer end of the outer frame 802. More than three springs 803 are fixedly arranged at equal intervals at the outer end of the outer frame 802. In this embodiment, the number of springs 803 is four. One end of the spring 803 is connected to the inner wall of the separation chamber 5. An elastic rubber ring 9 is fixedly arranged at the top end of the outer frame 802. The elastic rubber ring 9 is in a funnel shape. An installation ring 10 is fixedly arranged at the top end of the elastic rubber ring 9. The installation ring 10 is arranged on the inner wall of the separation chamber 5; a partition plate 12 is fixedly arranged on the inner wall of the separation chamber 5. The partition plate 12 is arranged at the bottom of the screening assembly 8. The upper plane of the partition plate 12 is inclined into a funnel. The bottom end of the funnel of the partition plate 12 is communicated with a delivery pipe 13 directly above the aggregate box 4. The delivery pipe 13 does not contact the aggregate box 4.

[0027] Among them, the mesh number of the screen 801 can be selected according to the diameter of the powdered raw material required to be prepared in step three. When the vibration motor 804 vibrates, the screen 801 shakes, and the powdered raw material with a diameter less than 13 μm on the screen 801 is screened into the lower partition plate 12.

[0028] After the solenoid valve is opened, the powdered raw material falls onto the screening assembly 8. The vibration motor 804 is turned on to make the screening assembly 8 vibrate. The powdered raw material with a diameter less than 13 μm is screened into the partition plate 12 and falls into the aggregate box 4 through the delivery pipe 13 by the partition plate 12.

[0029] One or more electric lifting and stirring mechanisms 14 are also provided at the bottom of the partition plate 12, and the electric lifting and stirring mechanisms 14 do not contact the conveying pipe 13. The electric lifting and stirring mechanisms 14 can be controlled to rise or fall by a controller, and when the electric lifting and stirring mechanisms 14 are not working, the electric lifting and stirring mechanisms 14 rise above the aggregate box 4.

[0030] The above-mentioned solenoid valve, dust collection device, metering pumping device 31, weighing device 15, vibration motor 804, electric lifting and stirring mechanism 14 and controller are all existing electronic devices.

[0031] The solenoid valve, dust collection device, metering pumping device 31, weighing device 15, vibration motor 804 and electric lifting and stirring mechanism 14 are respectively electrically connected to the controller.

[0032] When the weight of the powdered raw material falling into the aggregate box 4 weighed by the weighing device 15 reaches the preset weight value, the controller controls the solenoid valve to close, the vibration motor 804 stops vibrating, the metering pumping device 31 is turned on to pump flux into the aggregate box 4, and at the same time the electric lifting and stirring mechanism 14 descends to stir the powdered raw material and the flux evenly to form ceramic glaze. By accurately weighing the weight of the powdered raw material in the aggregate box 4 and accurately controlling the amount of flux pumped in according to the set ratio, the water content of the prepared ceramic glaze is 18%-22%, which is convenient for subsequent glazing; after stirring, the controller controls the electric lifting and stirring mechanism 14 to rise above the aggregate box 4.

[0033] When it is necessary to clean the powdered raw material that has not fallen through the sieve mesh 801, the controller controls the vibration motor 804 to vibrate, and the dust collection device is turned on to suck out the powdered raw material that has not fallen through the sieve mesh 801 from the dust collection pipe 2.

[0034] Furthermore, a transparent observation window 11 for observing the internal situation of the aggregate box 4 is provided on the aggregate tank 1. It is convenient for the staff to observe the stirring situation of the ceramic glaze from the transparent observation window 11.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
