Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a dust removal system for a silicon carbide substrate for strengthening glass sheets. Background Technology

[0002] Currently, in the process of strengthening glass sheets, such as tempered glass or chemically strengthened (ion-exchange) glass, high-temperature treatment is used to improve the mechanical strength of the glass. During the high-temperature treatment, silicon carbide cover plates are used on the upper and lower sides of the strengthened glass sheet. Through its high temperature resistance, high thermal conductivity, chemical inertness, mechanical stability and other characteristics, it is ensured that the glass achieves uniform heating / cooling, zero surface contamination, high-precision dimensional control and process stability during the strengthening process.

[0003] In the glass strengthening process, glass sheets are coated with a coating material using a roller coater before strengthening to give them excellent chemical properties. The coated glass sheets are then strengthened using a silicon carbide cover plate to improve their physical properties. The silicon carbide plate consists of a base plate and a cover plate. The glass sheet is placed between the base plate and the cover plate and fed into the annealing furnace via conveyor rollers. After annealing, dust is generated on the surface of the glass sheet due to the characteristics of the coating material. After annealing, the cover plate is removed by on-site workers for reuse in the next process; the silicon carbide base plate continues to be conveyed by the conveyor rollers to place new glass sheets for strengthening. However, during this process, the dust generated in the previous annealing process needs to be cleaned.

[0004] Currently, dust removal from silicon carbide substrates is generally done manually. Manual dust removal is not only cumbersome and time-consuming, but also lacks protective measures, resulting in dust scattering everywhere, requiring extensive cleaning, and posing a serious health risk to employees who inhale the dust over time. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, the purpose of this invention is to solve the problems of low efficiency, high pollution, and potential health hazards associated with manual dust removal. It provides a dust removal system for silicon carbide substrates used for strengthening glass sheets. This system utilizes an induction switch in conjunction with a blowing mechanism to blow dust from the substrate within a dust removal hood. The dust is then absorbed and discharged through a suction device, achieving automated dust removal and unified discharge of the absorbed dust. This effectively reduces manual intervention, significantly improves dust removal efficiency, and consumes less energy, thus saving costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a dust removal system for silicon carbide substrate plates used for strengthening glass sheets, comprising a frame with conveyor rollers, characterized in that: a dust removal device is provided above the frame, the dust removal device comprising a dust removal hood and a blowing mechanism, the blowing mechanism being mounted on the dust removal hood for blowing the substrate plates passing under the dust removal hood; further comprising: The dust collection device is connected to the dust collection hood via a connecting pipe and is used to suck out the dust inside the dust collection device; The control switch is used to control the start / stop of the blowing mechanism and the vacuuming device.

[0007] This solution involves installing a dust removal device above the rack. When the silicon carbide substrate passes beneath the dust removal device, the device uses a blowing mechanism to sweep the surface of the substrate, lifting the dust and suspending it within the device. A suction device then extracts the dust, effectively reducing dust pollution. The entire process can be controlled simply by switching on and off the dust removal and suction devices. This significantly reduces manual intervention, greatly improves dust removal efficiency, and saves costs.

[0008] Furthermore, the dust hood includes a front baffle, a rear baffle, two side plates, and a top plate. The front baffle, rear baffle, and two side plates are sequentially and sealed together to form an annular frame. The top plate is sealed to the upper side of the annular frame and closes the upper side of the annular frame. The two side plates are fixedly connected to the two sides of the frame. The blowing mechanism is located on one side plate or both side plates, and the dust collection device is connected to the top plate through connecting pipes.

[0009] This solution incorporates a blowing mechanism on the side panel of the dust hood, enabling better blowing of the silicon carbide substrate. Furthermore, the dust hood, in conjunction with the frame, forms a nearly enclosed space. Especially after the silicon carbide substrate enters, the space above it is essentially sealed. Thus, when the blowing mechanism blows across the surface of the silicon carbide substrate, the dust remains suspended in the space above it. When the dust collection device is activated, it can effectively remove the dust from the dust hood, significantly improving dust removal and collection efficiency.

[0010] Furthermore, the purging mechanism includes an air pipe connector and a nozzle. One end of the air pipe connector extends into the dust collector hood and connects to the nozzle, while the other end of the air pipe connector is used to connect to an air source device. The purging mechanism uses an air pipe connector and a nozzle, resulting in a simple overall structure. Furthermore, by utilizing the nozzle for purging, the purging pressure is higher, leading to better dust removal efficiency.

[0011] Furthermore, the nozzle is connected to the air pipe connector via a universal joint. This allows the nozzle's blowing direction to be adjusted in real time as needed, thereby improving the blowing effect.

[0012] Furthermore, the nozzle has a constricted nozzle orifice structure, which increases the nozzle's blowing area and improves the dust removal effect.

[0013] Furthermore, the upper sides of the two side plates of the dust collector hood are inclined in opposite directions, forming an angle of 45-60 degrees between the side plates and the horizontal plane; the axis of the nozzle is perpendicular to the side plate. With this design, the overall structure is simpler and installation is more convenient; simply connect the air pipe connector to the side plate.

[0014] Furthermore, there are multiple air pipe connectors and nozzles, distributed along the length of the frame on the side plates of the dust collector hood; wherein the multiple nozzles on the same side plate have different blowing directions. Using this solution, as the silicon carbide base plate moves, nozzles at different positions can blow on different parts of the silicon carbide base plate, further improving the blowing effect, resulting in better dust removal and higher efficiency on the surface of the silicon carbide base plate.

[0015] Furthermore, the distance between the front baffle and the rear baffle and the conveyor roller is greater than the thickness of the base plate; to ensure that the silicon carbide base plate can enter and exit the dust removal hood.

[0016] Furthermore, the distance between the front baffle and the rear baffle is greater than or equal to the length of the base plate. This ensures that the silicon carbide base plate has enough time to completely pass through the dust collection hood, thus allowing for a sufficiently long blowing time for the blowing mechanism to improve the dust removal effect on the surface of the silicon carbide base plate.

[0017] Furthermore, the control switch is an inductive switch. With the conveying direction of the conveyor rollers as a reference, the inductive switch is located in front of the dust collector and between two adjacent conveyor rollers, with its sensing end facing upwards and positioned below the upper side of the conveyor rollers. With this inductive switch, when the silicon carbide base plate moves above the inductive switch, it will be triggered. At this time, the inductive switch will activate the dust removal device and the vacuuming device to blow and remove dust from the silicon carbide surface.

[0018] Furthermore, it also includes a time-delay relay, wherein the inductive switch is connected in series with the control terminal of the time-delay relay, and the controlled terminal of the time-delay relay is connected in series with the dust removal device and the dust collection device.

[0019] This solution uses a combination of an inductive switch and a time-delay relay to control the blowing mechanism and the dust collection device to stop after a delay. This avoids the blowing mechanism and the dust collection device stopping immediately after the silicon carbide base plate is separated from the inductive switch, thus ensuring the working time of the blowing mechanism and the dust collection device. It also enables automatic control of the blowing mechanism and the dust collection device, achieving automated dust collection, significantly reducing manual intervention, and resulting in lower energy consumption and cost reduction.

[0020] Furthermore, it also includes a gas source device, which is connected to the purging mechanism via a gas supply pipe; the control switch is connected to the gas source device. The gas source device supplies gas to the purging mechanism to provide purging gas.

[0021] Furthermore, the dust collection device employs a pulse jet dust collector. Pulse jet dust collectors offer high purification efficiency, large gas handling capacity, stable performance, long filter bag life, and low maintenance costs.

[0022] Furthermore, a recycling box is provided below the frame, corresponding to the dust removal device, and the recycling box is detachably connected to the frame. The blowing mechanism mainly blows the upper surface of the silicon carbide substrate, but during the blowing process, dust from the lower surface of the silicon carbide substrate will also fall off. With the recycling box, the dust can be collected more effectively, avoiding environmental pollution.

[0023] Compared with the prior art, this utility model has the following advantages: By setting a dust removal hood on the frame, and then setting a blowing mechanism at least once on the dust removal hood, blowing gas is introduced to blow the bottom plate of the dust removal hood, and then a dust collection device connected to the dust removal hood absorbs and discharges the dust inside the dust removal hood; at the same time, an induction switch is set in front of the dust removal hood (in the direction of the conveying roller), and the induction switch controls the start and stop of the blowing mechanism and the dust collection device through a time delay relay, thereby realizing automated dust removal and uniformly discharging the absorbed dust. This effectively reduces the degree of manual intervention, greatly improves the dust removal efficiency, and has low energy consumption, which can effectively save costs.

[0031] Example: See Figure 1A dust removal system for silicon carbide substrates used for strengthening glass sheets includes a frame 1 with conveyor rollers 2. A dust removal device is located above the frame 1, comprising a dust removal hood 3 and a blowing mechanism 4. The blowing mechanism 4 is mounted on the dust removal hood 3 and is used to blow the substrate passing below the dust removal hood 3. The blowing mechanism 4 includes an air pipe connector and a nozzle. One end of the air pipe connector extends into the dust removal hood 3 and connects to the nozzle; the other end of the air pipe connector is connected to an air source device. The blowing mechanism 4 uses an air pipe connector and a nozzle, resulting in a simple overall structure. Furthermore, the use of the nozzle for blowing allows for higher blowing pressure and better dust removal. In implementation, the nozzle is connected to the air pipe connector via a universal joint. This allows the blowing direction of the nozzle to be adjusted in real time as needed, thereby improving the blowing effect. As an optimization, the nozzle's spray opening has a constricted structure, which increases the nozzle's blowing area and improves the dust removal effect. Specifically, the nozzle has a conical or wedge-shaped flat structure at the spray opening, which can increase the blowing power or the blowing area.

[0032] The dust collection device 5 is connected to the dust collection hood 3 via a connecting pipe 6, and is used to suck out the dust inside the dust collection device; the dust collection device 5 is a pulse dust collector. The pulse dust collector offers high purification efficiency, large gas handling capacity, stable performance, long filter bag life, and low maintenance costs.

[0033] The control switch is used to control the start / stop of the blowing mechanism 4 and the dust collection device 5. In implementation, the control switch is an inductive switch 7, located in front of the dust removal hood 3 and between two adjacent conveyor rollers, with its sensing end facing upwards and positioned below the upper side of the conveyor rollers. In implementation, the inductive switch 7 is connected to the frame 1 via a connecting bracket. With the inductive switch 7 installed, when the silicon carbide base plate 9 moves above the inductive switch 7, it will trigger the switch, which will then activate the dust removal device and the dust collection device 5 to blow and remove dust from the silicon carbide surface. The inductive switch 7 is a photoelectric switch or a proximity switch; it has high technological maturity, good stability, and lower cost.

[0034] This solution involves installing a dust removal device above the frame 1. When the silicon carbide substrate 9 passes beneath the dust removal device, the device uses a blowing mechanism 4 to blow the surface of the substrate 9, thus lifting the dust and suspending it within the device. Then, a suction device 5 extracts the dust from the dust removal device, effectively reducing dust pollution. Throughout the process, the dust removal device and suction device 5 can be controlled by a switch to start / stop them. This significantly reduces manual intervention, greatly improves dust removal efficiency, and effectively saves costs.

[0035] In implementation, the dust hood 3 includes a front baffle, a rear baffle, two side plates, and a top plate; wherein the front baffle, rear baffle, and two side plates are sequentially and sealed together to form an annular frame. The top plate is sealed to the upper side of the annular frame, thus sealing the upper side of the annular frame, i.e., the four sides of the top plate are sealed to the upper edges of the front baffle, rear baffle, and two side plates. The two side plates are fixedly connected to the two sides of the frame 1. Furthermore, during processing, the distance between the front and rear baffles and the conveyor roller 2 is greater than the thickness of the bottom plate; to ensure that the silicon carbide bottom plate 9 can enter and exit the dust hood 3. The distance between the front and rear baffles is greater than or equal to the length of the bottom plate. This ensures that the silicon carbide bottom plate 9 completely passes through the dust hood 3, thereby allowing the blowing time of the blowing mechanism 4 to be sufficiently long to improve the dust removal effect on the surface of the silicon carbide bottom plate 9.

[0036] The blowing mechanism 4 is located on one or both side plates, and the dust collection device 5 is connected to the top plate via a connecting pipe 6. This design, by installing the blowing mechanism 4 on the side plate of the dust hood 3, allows for better blowing of the silicon carbide base plate 9. Furthermore, the dust hood 3, together with the frame 1, forms a nearly enclosed space. Especially after the silicon carbide base plate 9 enters, its upper surface is essentially sealed off. Thus, when the blowing mechanism 4 blows across the surface of the silicon carbide base plate 9, the dust is suspended in the space above it. When the dust collection device 5 is activated, it can effectively remove the dust from the dust hood 3, significantly improving dust removal and collection efficiency. The upper sides of the two side plates of the dust hood 3 are inclined in opposite directions, forming an angle of 45-60 degrees between the side plates and the horizontal plane. The axis of the nozzles is perpendicular to the side plates, resulting in a larger blowing coverage area, essentially covering the entire silicon carbide base plate, thus improving the dust removal effect on the silicon carbide chassis. This solution simplifies the overall structure and makes installation easier; simply connect the air pipe connector to the side plate.

[0037] In implementation, multiple air pipe connectors and nozzles are distributed along the length of the frame 1 on the side plate of the dust collection hood 3; wherein, the multiple nozzles on the same side plate have different blowing directions. Using this solution, as the silicon carbide base plate 9 moves, nozzles at different positions can blow on different parts of the silicon carbide base plate 9, further improving the blowing effect, resulting in better dust removal and higher efficiency on the surface of the silicon carbide base plate 9.

[0038] In implementation, a time-delay relay is also included. The control terminal of the inductive switch 7 is connected in series with the time-delay relay, and the controlled terminal of the time-delay relay is connected in series with the dust removal device and the dust collection device 5. This solution, through the cooperation of the inductive switch 7 and the time-delay relay, controls the blowing mechanism 4 and the dust collection device 5 to stop after a delay. This avoids the blowing mechanism 4 and the dust collection device from immediately stopping after the silicon carbide base plate 9 separates from the inductive switch 7, thus ensuring the working time of the blowing mechanism 4 and the dust removal device. Furthermore, it enables automatic control of the blowing mechanism 4 and the dust removal device, achieving automated dust removal, significantly reducing manual intervention, and resulting in lower energy consumption and reduced costs.

[0039] In implementation, a gas source device is also included, which is connected to the purging mechanism 4 via a gas supply pipeline; the control switch is connected to the gas source device. The gas source device supplies gas to the purging mechanism 4 for purging. In this solution, the gas source device is an air compressor or a high-pressure air tank; when a high-pressure air tank is used, a solenoid valve is installed between the high-pressure air tank and the gas supply pipeline, and the control switch is connected to this solenoid valve. Using an air compressor or a high-pressure air tank as the gas source device simplifies the overall structure and makes control more convenient.

[0040] In practice, a recycling box 8 with an open top is also provided below the frame 1, corresponding to the position of the dust removal device. The recycling box 8 is detachably connected to the frame 1. The blowing mechanism 4 mainly blows the upper surface of the silicon carbide base plate 9, but during the blowing process, dust on the lower surface of the silicon carbide base plate 9 will also fall off. After setting up the recycling box 8, the dust can be collected better, avoiding environmental pollution.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
