Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing, and in particular to a glaze spraying device and process based on ceramic processing. Background Art

[0002] The glaze spraying device based on ceramic processing is a professional equipment used to apply glaze on the surface of ceramic products. By precisely controlling the spraying of the glaze, a uniform, smooth glaze with specific color and texture is formed on the ceramic surface, which can increase the gloss, color richness and artistic sense of the ceramic products, reduce errors in manual operation, improve production efficiency, and at the same time ensure the stability and consistency of product quality and reduce the defective rate.

[0003] Traditional glaze spraying relies on manual or fixed nozzle mechanical spraying. Manual operation can easily lead to uneven thickness and spray leakage, and it is difficult to cover curved parts 360°. There is insufficient spraying uniformity, and open spraying causes waste gas and dust to spread. The waste gas treatment has insufficient decomposition efficiency, low production efficiency and high maintenance cost. Based on this, a glaze spraying device and process based on ceramic processing are proposed for improvement. Summary of the Invention

[0004] In view of the problems of insufficient spraying uniformity, insufficient waste gas treatment and decomposition efficiency, low production efficiency and high maintenance cost in the above-mentioned prior art, the present invention is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a glaze spraying device based on ceramic processing, comprising a workbench, a spray box fixedly mounted on one side of the top of the workbench, a filter tube fixedly sleeved on one side of the spray box through a through slot, and a spray mechanism for spraying and a transmission mechanism for transmission provided above the workbench; A motor is fixedly installed on one side of the top of the spray box through an L-shaped plate, and a rotating column is fixedly sleeved on the output shaft of the motor, and the bottom end of the rotating column is rotatably connected to the top of the spray box, and a first sprocket is fixedly sleeved on the lower surface of the rotating column, and the first sprocket is rotatably connected to the second sprocket through a first chain, and a rotating drum is fixedly sleeved inside the second sprocket, and the rotating drum is rotatably connected to the top wall of the spray box, and a spray pipe is fixedly sleeved on one side of the bottom of the rotating drum, and a plurality of fan-shaped nozzles are threadedly connected to the surface of the spray pipe; A waste drawer is slidably connected to the bottom of the inner wall of the filter tube, a screen is fixedly connected to the lower part of the interior of the filter tube, a transmission shaft is provided inside the filter tube, the bottom end of the transmission shaft passes through the top of the screen and is fixedly connected to a scraper rod, the top end of the scraper rod is in contact with the bottom end of the screen, a number of ultraviolet lamps are fixedly installed in the middle part of the interior of the filter tube, and an activated carbon plate is fixedly installed at the outlet of the filter tube.

[0006] As a preferred solution of the glaze spraying device based on ceramic processing described in the present invention, wherein: a third sprocket is fixedly sleeved on the upper surface of the rotating column, the third sprocket is rotatably connected to the fourth sprocket through a second chain, a transmission shaft is fixedly sleeved inside the fourth sprocket, the upper part of the transmission shaft is rotatably connected to the top wall of the filter tube, an exhaust fan is fixedly sleeved on the middle surface of the transmission shaft, and the exhaust fan frame is fixedly installed on the upper inner part of the filter tube.

[0007] As a preferred solution of the glaze spraying device based on ceramic processing described in the present invention, a discharge barrel is fixedly installed on the other side of the top of the workbench, and a material pump is fixedly installed on the bottom wall of the discharge barrel.

[0008] As a preferred solution of the glaze spraying device based on ceramic processing described in the present invention, wherein: the output end of the material pump is fixedly sleeved with a material delivery pipe, and one end of the material delivery pipe is connected to the rotating drum through a rotary joint.

[0009] As a preferred solution of the glaze spraying device based on ceramic processing described in the present invention, a tray is fixedly installed on the bottom wall of the spray box, and a smooth anti-slip pad is fixedly connected to the top of the tray.

[0010] A process for using a glaze spraying device based on ceramic processing includes the following steps: Step 1: When the device needs to be used, first place the ceramic on the tray, then close the spray box and start the material pump. The material pump transports the glaze inside the discharge barrel through the feed pipe, rotary joint and rotating drum to the inside of the spray pipe, and then sprays it onto the ceramic from the fan-shaped nozzle; Step 2: Start the motor again, and the motor drives the rotating drum to rotate through the rotating column, the first sprocket, the first chain and the second sprocket, so that the spray pipe and the fan-shaped nozzle move in a circular motion with the rotating drum as the axis, so that they spray around the circumference of the ceramic; Step 3: As the rotating column rotates, the transmission shaft is driven to rotate through the third sprocket, the second chain, and the fourth sprocket, thereby rotating the exhaust fan to extract the exhaust gas inside the spray box; Step 4: After the exhaust gas from the spray box enters the filter tube, it first passes through a screen to intercept large particles, then passes through an ultraviolet lamp to decompose large molecular organic matter into small molecules, and then passes through an activated carbon plate for deep adsorption, and finally is discharged to the outside to complete the filtration; Step 5: As the drive shaft rotates, the scraper rod is driven to rotate, and the scraper rod scrapes off the large particles intercepted by the screen. The large particles fall into the waste drawer under the action of gravity, completing the collection.

[0011] In summary, the present invention has at least one of the following beneficial effects: 1.

On the other hand, the exhaust fan is synchronously driven by the transmission mechanism, which not only realizes the uniform spraying of the ceramic workpiece but also efficiently handles the waste gas and dust in the spraying process, thereby improving the environmental protection and safety of the process, reducing the number of power components, and reducing energy consumption and equipment costs.

[0012] 2. The present invention intercepts glaze particles through a screen, decomposes volatile organic compounds with ultraviolet lamps, and absorbs odors with activated carbon plates.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The embodiment of the present invention discloses a glaze spraying device and process based on ceramic processing.

[0019] Reference Figure 1-6 , which is the first embodiment of the present invention, provides a glaze spraying device based on ceramic processing, including a workbench 1, a spray box 2 is fixedly installed on one side of the top of the workbench 1, a filter tube 6 is fixedly sleeved on one side of the spray box 2 through a through groove 22, and a spraying mechanism for spraying and a transmission mechanism for transmission are provided above the workbench 1; A motor 41 is fixedly installed on one side of the top of the spray box 2 through an L-shaped plate. The output shaft of the motor 41 is fixedly sleeved with a rotating column 42. The bottom end of the rotating column 42 is rotatably connected to the top of the spray box 2. A first sprocket 43 is fixedly sleeved on the lower surface of the rotating column 42. The first sprocket 43 is rotatably connected to a second sprocket 45 through a first chain 44. A rotating drum 35 is fixedly sleeved inside the second sprocket 45. The rotating drum 35 is rotatably connected to the top wall of the spray box 2. A spray pipe 36 is fixedly sleeved on one side of the bottom of the rotating drum 35. A plurality of fan-shaped nozzles 37 are threadedly connected to the surface of the spray pipe 36. A discharge cylinder 31 is fixedly installed on the other side of the top of the workbench 1, and a material pump 32 is fixedly installed on the bottom wall of the discharge cylinder 31; The output end of the material pump 32 is fixedly connected with a material delivery pipe 33, and one end of the material delivery pipe 33 is connected to the rotating drum 35 through a rotary joint 34; A tray 21 is fixedly mounted on the bottom wall of the spray box 2 , and a smooth anti-skid pad is fixedly connected to the top of the tray 21 .

[0020] During use, when the device is needed, first place the ceramic on the tray 21, then close the spray box 2 and start the material pump 32. The material pump 32 extracts glaze from the discharge barrel 31 and conveys it to the rotary joint 34 through the material delivery pipe 33. The rotary joint 34 guides the glaze into the rotating drum 35, and then distributes it to each fan-shaped nozzle 37 through the spray pipe 36. Finally, it is sprayed in a fan-shaped atomized state to cover the surface of the ceramic workpiece. Start the motor 41, and its output shaft drives the rotating column 42 to rotate. The first sprocket 43 at the bottom of the rotating column 42 drives the second sprocket 45 to rotate through the first chain 44, thereby driving the rotating drum 35 to rotate synchronously. The rotating drum 35 drives the spray pipe 36 and the fan-shaped nozzle 37 to perform a circular motion around the ceramic workpiece, thereby achieving 360° uniform spraying; This design drives the spraying component to rotate through the transmission mechanism, cooperates with the material pump 32 of the spraying mechanism to deliver and the fan-shaped nozzle 37 to atomize, thereby realizing the automatic and uniform glaze spraying of the ceramic workpiece.

[0021] Reference Figure 1-6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a third sprocket 46 is fixedly sleeved on the upper surface of the rotating column 42, and the third sprocket 46 is rotatably connected to the fourth sprocket 48 through a second chain 47. A transmission shaft 49 is fixedly sleeved inside the fourth sprocket 48. The upper part of the transmission shaft 49 is rotatably connected to the top wall of the filter tube 6, and an exhaust fan 5 is fixedly sleeved on the middle surface of the transmission shaft 49. The exhaust fan 5 frame is fixedly installed on the upper part of the inner part of the filter tube 6.

[0022] During use, as the rotating column 42 rotates, the third sprocket 46 on its upper portion drives the fourth sprocket 48 to rotate via the second chain 47. The fourth sprocket 48 drives the transmission shaft 49 to rotate synchronously, causing the exhaust fan 5 installed in the filter tube 6 to rotate synchronously. The exhaust fan 5 draws the exhaust gas and dust in the spray box 2 into the filter tube 6 through the through slot 22, and discharges the clean air after filtration, thereby purifying the spraying environment. This design synchronously drives the spraying mechanism and the exhaust fan 5 through the transmission mechanism, which not only achieves uniform spraying of the ceramic workpiece, but also efficiently handles the exhaust gas and dust during the spraying process, thereby improving the environmental protection and safety of the process.

[0023] Reference Figure 1-6 , which is the third embodiment of the present invention, differs from the first embodiment in that: a waste drawer 61 is slidably connected to the bottom of the inner wall of the filter tube 6, and a screen 62 is fixedly connected to the lower part of the inner part of the filter tube 6; A transmission shaft 49 is provided inside the filter tube 6. The bottom end of the transmission shaft 49 passes through the top end of the screen 62 and is fixedly connected to a scraper rod 7. The top end of the scraper rod 7 contacts the bottom end of the screen 62. A plurality of ultraviolet lamps 63 are fixedly installed in the middle of the filter tube 6 , and an activated carbon plate 64 is fixedly installed at the outlet of the filter tube 6 .

[0024] During use, the exhaust gas containing glaze particles enters the filter tube 6 through the through slot 22, and the screen 62 intercepts the glaze particles in the airflow and preliminarily filters the exhaust gas. At the same time, the transmission shaft 49 drives the scraper 7 to rotate synchronously to prevent particles from clogging the screen holes and ensure filtering efficiency. The scraped particles fall into the waste drawer 61. The main body of the scraper 7 is made of 304 stainless steel with a thickness of 3-5mm, which has the characteristics of glaze corrosion resistance and high strength; the scraper end surface is inlaid with a polytetrafluoroethylene scraper with a thickness of 2-3mm. By utilizing its low friction coefficient and aging resistance, it reduces the wear on the screen and extends the service life of the screen 62 and the scraper 7, solving the contradiction between "effective scraping" and "protecting the screen 62"; Then, ultraviolet light is emitted by the ultraviolet lamp tube 63 to decompose the volatile organic compounds in the exhaust gas that has been preliminarily filtered by the screen 62, and kill any microorganisms that may be present. The ultraviolet lamp tube 63 uses an H-type low-pressure mercury lamp, model: ZW30S19W-H, with a single lamp power of 19W and a total power of 57-76W, which can not only ensure the decomposition efficiency of the resin volatiles in the exhaust gas, such as those in the glaze, but also avoid energy waste caused by excessive power. The main wavelength is 254nm. Ultraviolet light in this band has the strongest ability to break the molecular bonds of organic matter, and can efficiently decompose the large-molecule organic volatiles generated by glaze spraying, and can decompose large-molecule organic matter into small molecules. It is fixed with a bayonet type at both ends and matches the preset lamp holder inside the filter tube 6, which is convenient for later maintenance and replacement. The lamp tube shell is made of quartz glass, which is resistant to glaze dust corrosion and adapts to the complex environment inside the filter tube 6. The activated carbon plate 64 then absorbs the remaining odor and tiny particles, and finally discharges clean air. The activated carbon plate 64 uses a columnar activated carbon composite plate with a base material of coconut shell activated carbon. The thickness is 15-20mm, which can ensure the adsorption path length while avoiding excessive increase in wind resistance and not affecting the extraction efficiency of the exhaust fan 5. The particle size is 2-4mm and is mixed with 10% coal-based activated carbon to enhance the adsorption capacity of small molecular organic matter. It is pressed and formed with a food-grade adhesive, without the risk of secondary pollution, and is suitable for mixed pollutants such as benzene series, esters, and glaze dust that may be generated during glaze spraying. This design avoids manual cleaning of the frequently clogged screen 62 through the mechanical cooperation of the scraper rod 7 and the screen 62. The waste gas is physically filtered through the screen 62 and then chemically decomposed by the ultraviolet lamp 63, and then adsorbed and purified by the activated carbon plate 64, thereby ensuring that the waste gas meets the emission standards.

[0025] A process for using a glaze spraying device based on ceramic processing includes the following steps: Step 1: When the device is used, first place the ceramic on the tray 21, then close the spray box 2 and start the material pump 32. The material pump 32 transports the glaze inside the discharge barrel 31 through the material delivery pipe 33, the rotary joint 34 and the rotating drum 35 to the inside of the spray pipe 36, and then sprays the glaze from the fan-shaped nozzle 37 to the ceramic. Step 2: Start the motor 41 again. The motor 41 drives the rotating drum 35 to rotate through the rotating column 42, the first sprocket 43, the first chain 44 and the second sprocket 45, thereby causing the spray pipe 36 and the fan-shaped nozzle 37 to move in a circular motion around the rotating drum 35, so that the spraying is carried out around the circumference of the ceramic. Step 3: As the rotating column 42 rotates, the third sprocket 46, the second chain 47, and the fourth sprocket 48 drive the transmission shaft 49 to rotate, thereby rotating the exhaust fan 5 to extract the exhaust gas inside the spray box 2; Step 4: After the exhaust gas from the spray box 2 enters the filter tube 6, it first passes through the screen 62 to intercept large particles, then passes through the ultraviolet lamp 63 to decompose large molecular organic matter into small molecules, and then passes through the activated carbon plate 64 for deep adsorption, and finally is discharged to the outside to complete the filtration; Step 5: While the transmission shaft 49 rotates, the scraper rod 7 is driven to rotate. The scraper rod 7 scrapes off the large particles intercepted by the screen 62. The large particles fall into the waste drawer 61 under the action of gravity, completing the collection.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
