Description

Technical Field

[0001] This utility model belongs to the technical field of glass processing equipment, specifically a glass microsphere forming furnace. Background Technology

[0002] With the development of glass microsphere manufacturing technology, its application in reflective materials, road markings, aerospace, and composite materials is becoming increasingly widespread. The molding process of glass microspheres places high demands on product quality, sphericity, particle size uniformity, and production efficiency. Traditional glass microsphere molding equipment mostly uses the dripping method or centrifugal ejection method, forming microspheres from molten glass at high temperatures and then cooling and solidifying them to obtain the finished product. However, existing molding furnaces still have many shortcomings in achieving continuous operation, high precision, efficient cooling, and preventing adhesion, which restricts the large-scale production of high-quality glass microspheres.

[0003] A search revealed a glass forming drip furnace and glass forming system with publication number CN106904818B, published on January 24, 2023. This patent provides a glass microsphere preparation device based on crucible heating and drip forming from a discharge nozzle. The device uses gravity and surface tension to naturally form glass droplets into spheres, which are then collected after cooling. While this structure avoids the use of adhesives, is environmentally friendly, and has a simple forming process, it has significant drawbacks: First, the discharge nozzle is prone to deformation or blockage due to prolonged exposure to high-temperature molten glass, resulting in inconsistent droplet sizes and a wide microsphere particle size distribution. Second, the device lacks effective temperature control and atmosphere regulation along the drip path, leading to uneven cooling and potential microsphere deformation or internal stress concentration. Third, its single-point drip structure results in low production efficiency, making it unsuitable for large-scale continuous production.

[0004] A search revealed a molding furnace with publication number CN106477861B, published on March 1, 2019. This patent relates to a glass preform molding furnace with an isolated heating and cooling chamber structure, achieving rapid cooling through a lifting cooling mechanism that contacts the mold. This design effectively improves cooling speed and process cycle time, but it is mainly designed for molding flat or irregularly shaped glass products and is not suitable for the production process of freely formed glass microspheres. Its cooling method is contact mold cooling, which cannot be applied to the microsphere dripping scenario in moldless molding; furthermore, the furnace body lacks temperature gradient control and anti-adhesion measures for the microsphere falling channel. If used for microsphere molding, it is prone to causing microspheres to stick together or adhere to the furnace wall during cooling, resulting in blockage and product scrap.

[0005] The aforementioned problems indicate that existing molding furnaces either focus on compression molding or are limited to simple drop molding, lacking dedicated structural designs for the free formation, uniform cooling, anti-blocking, and continuous production of glass microspheres. Significant shortcomings exist, particularly in temperature field distribution, microsphere trajectory control, anti-clogging discharge, and efficient cooling, making it difficult to meet the industrial production requirements of high sphericity, narrow particle size distribution, and high cleanliness of glass microspheres. Therefore, a new type of molding furnace specifically designed for glass microsphere molding is urgently needed to achieve controllable temperature, uniform cooling, anti-blocking, and continuous stable production of high-quality microspheres.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] This utility model provides a glass microsphere molding furnace, the overall structure of which is as follows: Figure 1 As shown, the device includes a furnace body 1, a dripping assembly 2, a cooling assembly 3, and an anti-sticking assembly 4. The furnace body 1 forms the main frame of the entire device, with the dripping assembly 2 installed inside, the cooling assembly 3 located in the middle, and the anti-sticking assemblies 4 distributed around the outside of the cooling assembly 3. The specific implementation of each component is described in detail below with reference to the accompanying drawings.

[0021] The furnace body 1 has a feed inlet 5 at the top, and a sealing ring 501 is fixed to the inner wall of the feed inlet 5. The sealing ring 501 is made of silicone rubber with a thickness of 5mm to 8mm to ensure sealing during the feeding process. The furnace body 1 has a discharge outlet 6 at the bottom, and a removable filter screen 601 is installed on the inner wall of the discharge outlet 6. The filter screen 601 has a mesh size of 200 to 300 mesh and is used to filter out incompletely formed glass beads or other impurities to ensure the quality of the final product. A support frame 7 is symmetrically fixed to one side of the outer wall of the furnace body 1. A control panel 701 is installed at the end of the support frame 7. The surface of the control panel 701 is provided with three adjustment knobs 702, which are used to control the operating parameters of the heating ring 203, the temperature control unit 302 and the vibrator 401, respectively, so that the operator can adjust the working status of the equipment according to the actual needs.

[0022] The structure of the dripping component 2 is as follows: Figure 2As shown, the furnace includes a melting chamber 201, a perforated nozzle 202, a heating ring 203, and a flow equalization plate 204. The melting chamber 201 is embedded in the top of the furnace body 1 and is used to contain and melt the glass raw material. The bottom of the melting chamber 201 is fixedly connected to the perforated nozzle 202, and the bottom end of the perforated nozzle 202 is provided with conical guide surfaces 205. The surface of the conical guide surfaces 205 is coated with a high-temperature resistant ceramic coating, and the inclination angle is 30° to 45° to reduce the blockage caused by surface tension during the flow of the molten glass. The heating ring 203 is fitted on the outer wall of the perforated nozzle 202 and is fixedly connected to the inner wall of the furnace body 1 by bolts to maintain a constant temperature of the molten glass during the flow process. The melting chamber 201 is equipped with a flow equalizer 204. Multiple through holes are evenly distributed on the surface of the flow equalizer 204. The diameter and distribution density of these through holes are precisely calculated to ensure that the molten glass is evenly distributed before entering the porous outlet 202, thus guaranteeing the consistency of droplet size. The flow equalizer 204 is connected to the inner wall of the melting chamber 201 via a slot for easy disassembly and cleaning.

[0023] The structure of cooling component 3 is as follows Figure 3 As shown, the furnace includes a cooling chamber 301, a temperature control unit 302, an air guide plate 303, and a distribution pipe 304. The cooling chamber 301 is located in the middle of the furnace body 1 and is used to receive glass droplets dripping from the multi-hole outlet 202. The temperature control unit 302 is symmetrically installed on the outer side of the cooling chamber 301. The output end of the temperature control unit 302 penetrates the side wall of the cooling chamber 301 and extends into its interior, used for real-time monitoring and adjustment of the temperature inside the cooling chamber 301. An air guide plate 303 is fixed to the inner wall of the cooling chamber 301. The air guide plate 303 is spirally distributed, and its surface has several airflow channels. The width and spacing of the airflow channels are optimized to guide the airflow along a specific trajectory, forming a stable temperature gradient field. The bottom of the cooling chamber 301 is connected to four distribution pipes 304, with the outlet end of each distribution pipe 304 facing the center of the bottom of the furnace body 1, used to centrally transport the cooled glass microspheres to the outlet 6.

[0024] The structure of the anti-adhesion component 4 is as follows Figure 4As shown, the system includes a vibrator 401, an elastic baffle 402, a slide rail 403, and guide rods 404. The vibrator 401 is symmetrically mounted on the outer side of the cooling chamber 301. The output end of the vibrator 401 is fixedly connected to one side of the elastic baffle 402, and the other side of the elastic baffle 402 is slidably connected to the slide rail 403. The slide rail 403 is fixed to the inner wall of the cooling chamber 301 to limit the movement trajectory of the elastic baffle 402. Guide rods 404 are welded to the surface of the elastic baffle 402. The ends of the guide rods 404 penetrate the side wall of the cooling chamber 301 and are rotatably connected to the inner wall of the furnace body 1 via bearings to ensure the stability of the elastic baffle 402 during vibration. The surface of the elastic baffle 402 is provided with ventilation holes 405, each with a diameter of 1 mm to 2 mm and a quantity of 10 to 15 holes per square centimeter. These holes enhance airflow and reduce the risk of glass microspheres adhering to the inner wall of the cooling chamber 301 or the surface of the air guide plate 303. The elastic baffle 402 is made of nickel-based alloy with a thickness of 2 mm to 3 mm, exhibiting good high-temperature resistance and deformation resistance.

[0025] In actual operation, the glass raw material enters the melting chamber 201 through the feed inlet 5 and is heated to a molten state within the melting chamber 201. The molten glass flows into the porous outlet 202 after being evenly distributed by the flow equalization plate 204, and is maintained at a constant temperature under the action of the heating ring 203, avoiding blockage or deformation caused by temperature differences. The molten glass drips from the conical guide surface 205 of the porous outlet 202 into the cooling chamber 301. The air guide plate 303 in the cooling chamber 301 guides the airflow along a specific trajectory through a spiral design, forming a stable temperature gradient field to ensure that the glass microspheres are heated evenly during the cooling process and to reduce the occurrence of internal stress concentration. At the same time, the vibrator 401 in the anti-adhesion component 4 drives the elastic baffle 402 to vibrate periodically, preventing the glass microspheres from adhering to the inner wall of the cooling chamber 301 or the surface of the air guide plate 303. The design of the vent hole 405 further enhances airflow and reduces the risk of adhesion. The cooled glass microspheres are transported to the discharge port 6 through the diversion pipe 304 and discharged after being filtered by the filter screen 601, thus completing the entire production process.

[0026] In the above structure, the connection and positional relationships between the various components are precisely designed to ensure the stability and reliability of the equipment. For example, the melting chamber 201 and the multi-hole discharge nozzle 202 are connected by threads for easy disassembly and maintenance; the heating ring 203 is fixedly connected to the inner wall of the furnace body 1 by bolts to ensure its stability in high-temperature environments; the elastic baffle 402 and the slide rail 403 are connected by a sliding connection, which ensures both the flexibility of movement and limits the range of movement, preventing damage to the equipment due to excessive vibration.

[0027] In addition, the three adjustment knobs 702 on the control panel 701 are used to control the temperature of the heating ring 203, the cooling parameters of the temperature control unit 302, and the vibration frequency of the vibrator 401, respectively. Operators can flexibly adjust the working status of the equipment according to actual production needs. For example, when producing glass microspheres with smaller particle sizes, the temperature of the heating ring 203 can be appropriately increased and the cooling rate of the temperature control unit 302 can be decreased to extend the cooling time of the glass droplets, thereby obtaining a more uniform sphericity.

[0028] Through the synergistic effect of the above-described structure and operating principle, this invention achieves efficient production of glass microspheres, significantly improving the sphericity, particle size uniformity, and production efficiency of the products, thus meeting the practical needs of large-scale industrial production. To better enable those skilled in the art to fully understand and implement this invention, the specific implementation principle is further explained below in conjunction with a specific application scenario.

[0029] First, the operator adds the glass raw material into the melting chamber 201 through the feed inlet 5. During this process, the sealing ring 501 ensures the sealing of the feed, preventing external impurities from entering the furnace body 1. The silicone rubber sealing ring 501 has good high-temperature resistance and can adapt to the high-temperature environment inside the melting chamber 201. Subsequently, the heating device inside the melting chamber 201 heats the glass raw material to a molten state, making it fluid. The molten glass is evenly distributed under the action of the flow equalizer 204. The through holes on the surface of the flow equalizer 204 are precisely calculated to ensure that the pressure and flow rate of the molten glass are consistent, thereby avoiding differences in droplet size caused by uneven distribution.

[0030] Next, the molten glass flows into the porous nozzle 202 and is maintained at a constant temperature under the action of the heating ring 203. The heating ring 203 is fixed to the inner wall of the furnace body 1 by bolts, and its position and connection method ensure stability under high-temperature conditions. The conical guide surface 205 at the bottom of the porous nozzle 202 is designed with an inclination angle of 30° to 45° and is coated with a high-temperature resistant ceramic coating, which effectively reduces the clogging caused by surface tension during the flow of molten glass. The molten glass drips from the porous nozzle 202 into the cooling chamber 301, forming a preliminary microsphere morphology.

[0031] Upon entering the cooling chamber 301, the molten glass droplets flow along a specific trajectory under the influence of the air guide plate 303. The air guide plate 303 is spirally distributed, and its surface features optimized airflow channels to guide the cooling airflow and form a stable temperature gradient field. The temperature control unit 302 monitors the temperature within the cooling chamber 301 in real time and adjusts the cooling parameters as needed to ensure uniform heating of the molten glass droplets during cooling and reduce internal stress concentration. This temperature gradient field design allows the glass microspheres to gradually solidify during cooling, avoiding deformation or breakage caused by uneven cooling.

[0032] Meanwhile, the vibrator 401 in the anti-adhesion assembly 4 drives the elastic baffle 402 to vibrate periodically. The sliding connection between the elastic baffle 402 and the slide rail 403 restricts its movement trajectory. The guide rod 404 passes through the side wall of the cooling chamber 301 and is rotatably connected to the inner wall of the furnace body 1 through a bearing, ensuring the stability of the elastic baffle 402 during vibration. The vent holes 405 on the surface of the elastic baffle 402 enhance the airflow within the cooling chamber 301, reducing the risk of glass microspheres adhering to the inner wall of the cooling chamber 301 or the surface of the air guide plate 303. The nickel-based alloy elastic baffle 402 has good high-temperature resistance and deformation resistance, enabling it to operate stably for a long time in high-temperature environments.

[0033] After cooling, the glass microspheres are conveyed to the discharge port 6 via four diversion pipes 304, with their outlets facing the center of the bottom of the furnace body 1 to ensure uniform collection of the glass microspheres. A filter screen 601 on the inner wall of the discharge port 6 filters out incompletely formed glass microspheres or other impurities, ensuring the quality of the final product. The filter screen 601 is detachable for easy regular cleaning and replacement.

[0034] Throughout the operation, the three adjustment knobs 702 on the control panel 701 are used to adjust the temperature of the heating ring 203, the cooling parameters of the temperature control unit 302, and the vibration frequency of the vibrator 401, respectively. For example, when producing glass microspheres with smaller particle sizes, the operator can appropriately increase the temperature of the heating ring 203 to increase the fluidity of the molten glass; at the same time, reduce the cooling rate of the temperature control unit 302 to extend the cooling time of the molten glass droplets, thereby obtaining a more uniform sphericity. In addition, the vibration frequency of the vibrator 401 can be flexibly adjusted according to actual needs to further optimize the anti-sticking effect. A heat insulation layer is provided on the inner wall of the furnace body, and the heat insulation layer is made of ceramic fiber.

[0035] Through the aforementioned steps and the synergistic effect of each component, this invention achieves efficient production of glass microspheres. The threaded connection between the melting chamber 201 and the porous discharge nozzle 202 facilitates disassembly and maintenance. The bolted fixing of the heating ring 203 to the inner wall of the furnace body 1 ensures stability under high-temperature conditions. The sliding connection between the elastic baffle 402 and the slide rail 403 ensures both flexibility of movement and avoids damage to the equipment caused by excessive vibration. These design details collectively ensure the stability and reliability of the equipment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
