Description

Technical Field

[0001] This invention relates to the field of glass microsphere preparation technology, specifically to a high-temperature molten microdroplet collision device and method. Background Technology

[0002] Glass microspheres, as a high-performance functional material, have been widely used in various high-tech fields and civilian applications, including electronic device packaging, traffic reflective signs, aerospace materials, and environmental protection, thanks to their excellent mechanical strength, optical refractive index, high-temperature resistance, and chemical stability. The core performance characteristics of glass microspheres are closely related to the droplet formation quality during their preparation. The regularity and density of the droplet formation directly determine key indicators such as the sphericity and internal porosity of the glass microspheres, thus affecting their subsequent performance and lifespan.

[0003] In the melt-processing of glass microspheres, droplet collision is a crucial step in optimizing the internal structure of the microspheres and improving product performance. By precisely controlling the collision parameters of the high-temperature molten droplets (including collision angle, collision force, and collision timing), it is possible to effectively promote the full fusion of the molten droplets, eliminate internal air bubbles, and thus significantly improve the sphericity of the glass microspheres, reduce internal porosity, and ultimately enhance their core application properties such as mechanical strength, refractive index, and wear resistance, meeting the high-performance requirements of glass microspheres in various fields.

[0004] However, in current glass microsphere preparation processes, the droplet collision stage mostly employs natural dripping collision or simple jet collision. These methods suffer from numerous insurmountable technical defects, failing to meet the demands of large-scale, precise industrial production. Specific defects include: low collision accuracy; existing collision devices lack precise parameter control mechanisms, making it impossible to accurately control the collision angle, height, force, and timing of two or more high-temperature molten droplets, resulting in extremely poor droplet collision stability; some molten droplets are prone to collision deviation, insufficient collision force, or excessive collision, directly causing a low yield of glass microspheres. Furthermore, the finished microspheres generally exhibit uneven sphericity, high internal porosity, and numerous surface defects, severely impacting their subsequent performance in high-end applications and limiting the upgrading and industrial development of glass microsphere products.

[0005] Given the shortcomings of the existing technologies, in order to solve the technical problems of low droplet collision accuracy, unstable effect, and poor product quality in the preparation of glass microspheres, meet the needs of precise industrial production, and improve the performance and yield of glass microspheres, it is necessary to invent a high-temperature melting microdroplet collision device and method. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A high-temperature molten microdroplet collision device includes a collision box, wherein a plurality of lifting components are arranged in a ring in the inner cavity of the collision box, and two sets of collision components are symmetrically arranged on the lifting components.

[0008] The collision assembly includes a crucible, a first rigid tube fixedly installed at the bottom of the crucible, a telescopic flexible tube fixedly installed at one end of the first rigid tube, a second rigid tube fixedly installed at one end of the telescopic flexible tube, a nozzle fixedly installed at one end of the second rigid tube, and an adjustment assembly for adjusting the nozzle angle is provided at the bottom of the crucible.

[0009] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, the bottom of the collision box is provided with several support rods arranged in a ring and fixedly installed, and a discharge pipe is fixedly installed in the middle of the bottom end of the collision box, and a valve is provided on the discharge pipe.

[0010] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, the top of the collision box is provided with a box cover, and a hand handle is fixedly installed on the top of the box cover.

[0011] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, the lifting assembly includes:

[0012] Linear motors are fixedly installed on the inner surface of the collision box;

[0013] A horizontal plate is fixedly mounted on the slider of a linear motor, and crucibles are fixedly mounted on both ends of the horizontal plate.

[0014] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, the adjustment component includes:

[0015] Square plates are fixedly installed at both ends of the bottom of the crucible;

[0016] A rotating shaft is rotatably connected to a square plate via a bearing, and a second rigid tube is fixedly installed between the two sets of rotating shafts.

[0017] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, a servo motor is fixedly installed on the outer side of a group of square plates, and the output shaft of the servo motor is fixedly connected to the rotating shaft.

[0018] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, an electric heating element is fixedly installed on the inner surface of the crucible to heat the inner cavity of the crucible.

[0019] As a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, the crucible is provided with a lid on top to enable the crucible cavity to be in a sealed environment.

[0020] In a preferred embodiment of the high-temperature molten microdroplet collision device of the present invention, an air inlet pipe is fixedly installed in the middle of the pot lid to inject air into the crucible.

[0021] A method for collision of high-temperature molten microdroplets includes the following specific steps:

[0022] S1. Open the box lid by holding the lever, put the glass raw materials into each crucible, close the lid, and connect the air inlet pipe to the external air pump.

[0023] S2 activates the electric heating element to heat the glass raw material in the crucible until it is completely melted and forms high-temperature molten droplets;

[0024] S3. According to the preparation requirements, adjust the lifting height of the linear motor to drive the horizontal plate and crucible to lift and lower, and determine the height of the droplet collision; at the same time, make the servo motor drive the rotating shaft to rotate, so that the rotating shaft drives the second rigid tube and nozzle to rotate, and adjust the spray angle of the nozzle so that the symmetrically set nozzles are aligned with the preset collision point.

[0025] S4. After adjustment, start the external air pump. The air pump injects air into the crucible through the air inlet pipe. Under the action of air pressure, the molten droplets in the crucible pass through the first rigid tube, the telescopic flexible tube, and the second rigid tube in sequence, and finally spray out from the nozzle. The droplets sprayed from different nozzles collide precisely in the collision chamber to form glass microspheres.

[0026] The beneficial effects of this invention are:

[0027] By incorporating adjustment components, the droplet collision angle can be precisely controlled, solving the problems of low collision accuracy and inaccurate angle control in existing devices. Simultaneously, by incorporating lifting components, the droplet collision height can be flexibly adjusted, adapting to the preparation needs of glass microspheres of different specifications and addressing the poor versatility of existing devices. Based on the above, the synergistic effect of the overall structure improves the yield of glass microspheres and optimizes their structure and performance, solving the problems of low yield and poor microsphere performance in existing devices.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] This embodiment is a high-temperature molten microdroplet collision device. Please refer to [link / reference]. Figures 1-6 The device includes a collision chamber 10, the inner cavity of which is provided with several lifting components arranged in a ring, and two sets of collision components are symmetrically arranged on the lifting components. Several support rods 11 are fixedly installed in a ring at the bottom of the collision chamber 10. The support rods 11 are used to support the entire device, ensure the stability of the device during operation, and avoid the impact of device shaking on the droplet collision accuracy. A discharge pipe 12 is fixedly installed in the middle of the bottom end of the collision chamber 10, and a valve is provided on the discharge pipe 12. After the molten microdroplets are cooled and solidified after the collision, the valve can be opened to discharge the finished glass microbeads through the discharge pipe 12 for easy collection and subsequent processing. The top of the collision chamber 10 is provided with a box cover 13, and a hand handle 14 is fixedly installed on the top of the box cover 13. The hand handle 14 makes it easy for the operator to open or close the box cover 13. The box cover 13 can seal the inside of the collision chamber 10, reduce the interference of the external environment on the droplet collision process, and prevent the high-temperature molten droplets from splashing and causing safety hazards.

[0039] The collision assembly includes a crucible 30, a first rigid tube 40, a telescopic flexible tube 41, a second rigid tube 42, and a nozzle 43;

[0040] A first rigid tube 40 is fixedly installed at the bottom of the crucible 30, communicating with the inner cavity of the crucible 30 for conveying molten droplets within the crucible 30. A telescopic flexible tube 41 is fixedly installed at one end of the first rigid tube 40. The telescopic flexible tube 41 is telescopic and flexible, allowing adjustment of the nozzle 43 angle using an adjustment component, preventing obstruction of droplet delivery during angle adjustment. A second rigid tube 42 is fixedly installed at one end of the telescopic flexible tube 41, fixing the nozzle 43 to ensure its stability and precise droplet ejection. A nozzle 43 is fixedly installed at one end of the second rigid tube 42, ejecting molten droplets at a preset speed and flow rate to achieve precise droplet collision. An adjustment component is provided at the bottom of the crucible 30 for adjusting the nozzle 43 angle, allowing flexible adjustment of the nozzle 43's ejection angle to meet different collision requirements. To meet the requirements of the collision scene; an electric heating element 31 is fixedly installed on the inner surface of the crucible 30 to heat the inner cavity of the crucible 30. The electric heating element 31 is controlled by an external controller and powered by mains electricity. The heating temperature can be precisely adjusted according to the melting requirements of the glass raw materials to ensure that the raw materials can be fully melted and to maintain the stable state of the molten droplets, preventing the droplets from cooling and solidifying; a lid 32 is provided on the top of the crucible 30 to keep the inner cavity of the crucible 30 in a sealed environment, reducing the contact between the molten droplets and air, preventing the droplets from oxidizing, and reducing heat loss, thus saving energy; an air inlet pipe 33 is fixedly installed in the middle of the lid 32 to inject air into the crucible 30. The air inlet pipe 33 is connected to an external air pump, which is controlled by a controller. The air inlet pressure can be adjusted as needed to provide power for the delivery of molten droplets by injecting air, ensuring that the droplets can be smoothly and uniformly ejected from the nozzle 43 through the pipe.

[0041] The lifting assembly includes: a linear motor 20 and a horizontal plate 21;

[0042] Several linear motors 20 are fixedly installed on the inner surface of the collision box 10. The linear motors 20 are controlled by an external controller and powered by an external mains power supply, which can precisely control the lifting height of the slider. The horizontal plate 21 is fixedly installed on the slider of the linear motor 20, and crucibles 30 are fixedly installed at both ends of the horizontal plate 21. The horizontal plate 21 is driven to lift and lower by the linear motor 20, which in turn drives the crucibles 30 and the collision components to lift and lower as a whole, so as to achieve precise adjustment of the droplet collision height and adapt to the preparation needs of glass microspheres of different specifications.

[0043] The adjustment assembly includes: a square plate 50, a rotating shaft 51, and a servo motor 52;

[0044] Square plates 50 are fixedly installed at both ends of the bottom of the crucible 30. The square plates 50 are used to install the rotating shaft 51 and the servo motor 52, which serve to fix and support them. The rotating shaft 51 is rotatably connected to the square plate 50 through bearings, and a second rigid tube 42 is fixedly installed between the two sets of rotating shafts 51. The rotating shaft 51 can drive the second rigid tube 42 to rotate synchronously, thereby driving the nozzle 43 to adjust its angle. A servo motor 52 is fixedly installed on the outer side of one set of square plates 50, and the output shaft of the servo motor 52 is fixedly connected to the rotating shaft 51. The servo motor 52 is controlled by an external controller and powered by an external mains power supply. It can precisely control the rotation angle of the rotating shaft 51, thereby achieving precise control of the spray angle of the nozzle 43 and ensuring that the droplets sprayed from multiple nozzles can collide accurately.

[0045] A method for collision of high-temperature molten microdroplets includes the following specific steps:

[0046] S1, open the box cover 13 by holding the lever 14, put the glass raw materials into each crucible 30, cover the pot cover 32, and connect the air inlet pipe 33 to the external air pump;

[0047] S2, activate the electric heating element 31 to heat the glass raw material in the crucible 30 until the raw material is completely melted and forms high-temperature molten droplets;

[0048] S3, according to the preparation requirements, adjust the lifting height of the linear motor 20 to drive the horizontal plate 21 and crucible 30 to lift and lower, and determine the height of the droplet collision; at the same time, make the servo motor 52 drive the rotating shaft 51 to rotate, so that the rotating shaft 51 drives the second rigid tube 42 and the nozzle 43 to rotate, adjust the spray angle of the nozzle 43, and make the symmetrically arranged nozzles 43 aligned with the preset collision point.

[0049] S4. After adjustment, start the external air pump. The air pump injects air into the crucible 30 through the air inlet pipe 33. Under the action of air pressure, the molten droplets in the crucible 30 pass through the first rigid pipe 40, the telescopic flexible pipe 41, and the second rigid pipe 42 in sequence, and finally spray out from the nozzle 43. The droplets sprayed from different nozzles collide precisely in the collision box 10 to achieve the formation of glass microspheres.

[0050] Specifically, firstly, the lid 13 is opened using the hand lever 14, and the glass raw material is placed into each crucible 30. The lid 32 is then closed, and the air inlet pipe 33 is connected to the external air pump. The connections of all components are checked for secureness. Next, the device is started using the external controller. The controller activates the electric heating elements 31 to heat the glass raw material in the crucible 30 until it completely melts and forms high-temperature molten droplets. During heating, the temperature of the electric heating elements 31 can be adjusted by the controller to maintain a stable molten state of the droplets. Then, according to the preparation requirements, the lifting height of the linear motor 20 is adjusted by the controller, causing the horizontal plate 21 and crucible 30 to rise and fall, determining the height of droplet collision. Simultaneously, the servo motor 52 is activated by the controller, driving the rotating shaft 51 to rotate. The rotating shaft 51 then drives the second rigid tube 42 and the nozzle 43 to rotate. Adjust the spray angle of nozzle 43 so that the symmetrically arranged nozzles 43 are aligned with the preset collision point. After adjustment, start the external air pump through the controller. The air pump injects air into the crucible 30 through the air inlet pipe 33. Under the action of air pressure, the molten droplets in the crucible 30 pass through the first rigid pipe 40, the telescopic flexible pipe 41, and the second rigid pipe 42 in sequence, and finally spray out from the nozzle 43. The droplets sprayed from different nozzles collide precisely in the collision box 10 to form glass microspheres. During the collision process, the parameters of the linear motor 20, servo motor 52, electric heating element 31 and air pump can be adjusted in real time through the controller to ensure stable collision effect. After the collision is completed, turn off all electrical components. After the molten droplets cool and form glass microspheres, open the valve on the discharge pipe 12 to collect the finished glass microspheres through the discharge pipe 12, completing one preparation process.
