Description

Technical Field

[0001] This invention relates to the field of ceramic processing technology, and specifically to a glaze spraying device and process based on ceramic processing. Background Technology

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

[0003] Traditional glaze spraying relies on manual or fixed-nozzle mechanical spraying. Manual operation is prone to uneven thickness and missed spraying, and it is difficult to cover curved parts 360°. There is insufficient spraying uniformity, and open spraying causes the spread of exhaust gas and dust. Exhaust gas treatment has insufficient decomposition efficiency, as well as low production efficiency and high maintenance costs. Based on this, a glaze spraying device and process based on ceramic processing is proposed for improvement. Summary of the Invention

[0004] In view of the problems of insufficient coating uniformity, insufficient waste gas treatment and decomposition efficiency, low production efficiency and high maintenance costs in the existing technology, the present invention is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glaze spraying device based on ceramic processing, comprising a worktable, a spraying box fixedly installed on one side of the top of the worktable, a filter tube fixedly sleeved on one side of the spraying box through a through groove, and a spraying mechanism for spraying and a transmission mechanism for transmission provided above the worktable.

[0006] A motor is fixedly installed on one side of the top of the spray box via an L-shaped plate. A rotating column is fixedly sleeved on the output shaft of the motor. The bottom end of the rotating column is rotatably connected to the top of the spray box. A first sprocket is fixedly sleeved on the lower surface of the rotating column. A second sprocket is rotatably connected to the first sprocket via a first chain. A rotating cylinder is fixedly sleeved inside the second sprocket. The rotating cylinder is rotatably connected to the top wall of the spray box. A spray pipe is fixedly sleeved on one side of the bottom of the rotating cylinder. Several fan-shaped nozzles are threaded onto the surface of the spray pipe.

[0007] 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 filter tube. A drive shaft is provided inside the filter tube. The bottom end of the drive shaft passes through the top end of the screen and is fixedly connected to a scraper. The top end of the scraper contacts the bottom end of the screen. Several ultraviolet lamps are fixedly installed in the middle of the filter tube. An activated carbon plate is fixedly installed at the outlet of the filter tube.

[0008] As a preferred embodiment of the glaze spraying device based on ceramic processing described in this invention, wherein: a third sprocket is fixedly sleeved on the upper surface of the rotating column, the third sprocket is rotatably connected to a fourth sprocket via a second chain, a drive shaft is fixedly sleeved inside the fourth sprocket, the upper part of the drive shaft is rotatably connected to the top wall of the filter tube, an exhaust fan is fixedly sleeved on the middle surface of the drive shaft, and the exhaust fan frame is fixedly installed inside the upper part of the filter tube.

[0009] As a preferred embodiment of the glaze spraying device based on ceramic processing described in this invention, a discharge cylinder 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 cylinder.

[0010] As a preferred embodiment of the glaze spraying device based on ceramic processing described in this invention, the output end of the material pump is fixedly connected to a material conveying pipe, and one end of the material conveying pipe is connected to the rotating drum through a rotary joint.

[0011] As a preferred embodiment of the glaze spraying device based on ceramic processing described in this invention, a tray is fixedly installed on the bottom wall of the spraying box, and a smooth anti-slip pad is fixedly connected to the top of the tray.

[0012] A process for using a glaze spraying device based on ceramic processing includes the following steps:

[0013] Step 1: When the device is needed, first place the ceramic on the tray, then close the spray box and start the material pump. The material pump will transport the glaze inside the discharge cylinder through the conveying pipe, rotary joint and rotating drum into the spray pipe, and then spray it onto the ceramic from the fan-shaped nozzle.

[0014] Step two, start the motor again. The motor drives the rotating drum to rotate through the rotating column, the first sprocket, the first chain and the second sprocket. This causes the spray pipe and the fan-shaped nozzle to move in a circle around the rotating drum as the axis, so that they spray around the circumference of the ceramic.

[0015] Step 3: As the rotating column rotates, the drive shaft is driven to rotate through the third sprocket, the second chain and the fourth sprocket, which in turn causes the exhaust fan to rotate and extract the exhaust gas from inside the spray box.

[0016] Step 4: After the exhaust gas inside the spray booth enters the filter tube, it first passes through the screen to intercept large particles, then passes through the ultraviolet lamp to decompose large organic molecules into small molecules, then passes through the activated carbon plate for deep adsorption, and finally is discharged to the outside to complete the filtration.

[0017] Step 5: As the drive shaft rotates, it drives the scraper to rotate as well. The scraper scrapes off the large particles intercepted by the screen. Under the action of gravity, the large particles fall into the waste drawer, completing the collection.

[0018] In summary, the present invention has at least one of the following beneficial effects:

[0019] 1. On the one hand, this invention drives the spraying component to rotate through a transmission mechanism, which, together with the material pump conveying and fan-shaped nozzle atomization of the spraying mechanism, achieves a wide coverage area and uniform trajectory, realizing automated and uniform glaze spraying of ceramic workpieces and improving the consistency of glaze adhesion on the ceramic surface. On the other hand, the transmission mechanism synchronously drives the exhaust fan, which, while achieving uniform spraying of ceramic workpieces, efficiently handles waste gas and dust during the spraying process, improving the environmental protection and safety of the process, and reducing the number of power components, thus reducing energy consumption and equipment costs.

[0020] 2. This invention uses a sieve to intercept glaze particles, an ultraviolet lamp to decompose volatile organic compounds, and an activated carbon plate to adsorb odors. The emitted gas meets national environmental protection standards. Solid waste is collected through a waste drawer and can be melted and reused, reducing production costs.

[0021] 3. This invention uses a drive shaft to drive a scraper to continuously scrape the bottom surface of the screen, thereby preventing particles from accumulating and clogging, maintaining stable filtration efficiency, and reducing the frequency of manual cleaning. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention discloses a glaze spraying device and process based on ceramic processing.

[0033] Reference Figure 1-6 The first embodiment of the present invention provides a glaze spraying device based on ceramic processing, including a workbench 1, a spraying box 2 fixedly installed on one side of the top of the workbench 1, a filter tube 6 fixedly sleeved on one side of the spraying box 2 through a through groove 22, and a spraying mechanism for spraying and a transmission mechanism for transmission provided above the workbench 1.

[0034] A motor 41 is fixedly installed on one side of the top of the spray box 2 via an L-shaped plate. A rotating column 42 is fixedly sleeved on the output shaft of the motor 41. 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 via a first chain 44. A rotating cylinder 35 is fixedly sleeved inside the second sprocket 45. The rotating cylinder 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 cylinder 35. Several fan-shaped nozzles 37 are threadedly connected to the surface of the spray pipe 36.

[0035] 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.

[0036] The output end of the material pump 32 is fixedly connected to the material conveying pipe 33, and one end of the material conveying pipe 33 is connected to the rotating drum 35 through the rotary joint 34;

[0037] A tray 21 is fixedly installed on the bottom wall of the spray box 2, and a smooth anti-slip pad is fixedly connected to the top of the tray 21.

[0038] 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 draws glaze from the discharge cylinder 31 and delivers it to the rotary joint 34 through the material conveying pipe 33. The rotary joint 34 guides the glaze into the rotating cylinder 35, and then distributes it to each fan-shaped nozzle 37 through the spraying pipe 36. Finally, it is sprayed out in a fan-shaped atomized state to cover the surface of the ceramic workpiece.

[0039] The motor 41 is started, 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 spray head 37 to make a circular motion around the ceramic workpiece, thereby achieving 360° uniform spraying.

[0040] This design drives the spraying components to rotate through a transmission mechanism, which, in conjunction with the material pump 32 of the spraying mechanism for conveying and the fan-shaped nozzle 37 for atomization, enables automated and uniform glaze spraying of ceramic workpieces.

[0041] Reference Figure 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a third sprocket 46 is fixedly sleeved on the upper surface of the rotating column 42, the third sprocket 46 is rotatably connected to a fourth sprocket 48 through a second chain 47, a drive shaft 49 is fixedly sleeved inside the fourth sprocket 48, the upper part of the drive shaft 49 is rotatably connected to the top wall of the filter tube 6, an exhaust fan 5 is fixedly sleeved on the middle surface of the drive shaft 49, and the frame of the exhaust fan 5 is fixedly installed inside the upper part of the filter tube 6.

[0042] During use, while the rotating column 42 rotates, the third sprocket 46 on its upper part drives the fourth sprocket 48 to rotate through the second chain 47. The fourth sprocket 48 drives the transmission shaft 49 to rotate synchronously, so that the exhaust fan 5 installed in the filter pipe 6 rotates synchronously. The exhaust fan 5 draws the exhaust gas and dust in the spray box 2 into the filter pipe 6 through the channel 22, and after filtration, clean air is discharged, thereby purifying the spraying environment.

[0043] This design synchronously drives the spraying mechanism and exhaust fan 5 through a transmission mechanism, achieving uniform spraying of ceramic workpieces while efficiently handling waste gas and dust during the spraying process, thus improving the environmental friendliness and safety of the process.

[0044] Reference Figure 1-6 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is 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 inside of the filter tube 6.

[0045] The filter tube 6 is equipped with a drive shaft 49. The bottom end of the drive shaft 49 passes through the top end of the screen 62 and is fixedly connected to a scraper 7. The top end of the scraper 7 is in contact with the bottom end of the screen 62.

[0046] Several 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.

[0047] During use, exhaust gas containing glaze particles enters the filter pipe 6 through the channel 22. The screen 62 intercepts the glaze particles in the airflow, initially filtering the exhaust gas. At the same time, the drive shaft 49 drives the scraper 7 to rotate synchronously, preventing particles from clogging the screen holes and ensuring filtration 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 being resistant to glaze corrosion and having high strength. The scraper end surface is inlaid with polytetrafluoroethylene scraper blades with a thickness of 2-3mm. Utilizing its low coefficient of friction and aging resistance, it reduces wear on the screen and extends the service life of the screen 62 and the scraper 7, thus resolving the contradiction between "effective cleaning" and "protecting the screen 62".

[0048] Next, ultraviolet light is emitted through ultraviolet lamp 63 to decompose the volatile organic compounds in the exhaust gas that has been preliminarily filtered by screen 62, and kill any microorganisms that may be present. Ultraviolet lamp 63 is an H-type low-pressure mercury lamp, model: ZW30S19W-H, with a single lamp power of 19W and a total power of 57-76W. This ensures efficient decomposition of volatile components such as resin in glaze in the exhaust gas, while avoiding 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 large molecular organic volatiles generated by glaze spraying. It can decompose large molecular organics into small molecules. It is fixed with bayonet at both ends and matches the lamp holder preset inside the filter tube 6, which is convenient for later maintenance and replacement. The outer shell of the lamp tube is made of quartz glass, which is resistant to glaze dust corrosion and adapts to the complex environment inside the filter tube 6.

[0049] Then, the remaining odors and fine particles are adsorbed by the activated carbon plate 64, and finally clean air is discharged. The activated carbon plate 64 is a columnar activated carbon composite plate with coconut shell activated carbon as the base material. The thickness is 15-20mm to ensure the adsorption path length, while avoiding excessive wind resistance and not affecting the air extraction efficiency of the exhaust fan 5. The particle size is 2-4mm, and 10% coal-based activated carbon is mixed to enhance the adsorption capacity of small molecule organic matter. It is pressed and molded with food-grade adhesive, so there is no risk of secondary pollution. It is suitable for mixed pollutants such as benzene series, esters, and glaze dust that may be generated during glaze spraying.

[0050] This design avoids frequent manual cleaning of the screen 62 by mechanically cooperating with the scraper 7. The screen 62 is physically filtered, then chemically decomposed by the ultraviolet lamp 63, and finally adsorbed and purified by the activated carbon plate 64, thus ensuring that the exhaust gas meets the emission standards.

[0051] A process for using a glaze spraying device based on ceramic processing includes the following steps:

[0052] Step 1: 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 delivers the glaze inside the discharge cylinder 31 through the conveying pipe 33, rotary joint 34 and rotating drum 35 to the inside of the spray pipe 36, and then sprays it onto the ceramic from the fan-shaped nozzle 37.

[0053] 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 circle around the rotating drum 35 as the axis, so that they spray around the circumference of the ceramic.

[0054] Step 3: As the rotating column 42 rotates, the transmission shaft 49 is driven to rotate through the third sprocket 46, the second chain 47 and the fourth sprocket 48, which in turn causes the exhaust fan 5 to rotate and extract the exhaust gas inside the spray box 2.

[0055] Step 4: After the exhaust gas inside 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 tube 63 to decompose large organic molecules into small molecules, then passes through the activated carbon plate 64 for deep adsorption, and finally is discharged to the outside to complete the filtration.

[0056] Step 5: As the drive shaft 49 rotates, it drives the scraper 7 to rotate as well. The scraper 7 scrapes off the large particles intercepted by the screen 62. Under the action of gravity, the large particles fall into the waste drawer 61, completing the collection.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
