Description

Technical Field

[0001] This utility model belongs to the field of glass tube production technology, and in particular relates to a glass tube atomizing device. Background Technology

[0002] High-temperature molded glass tubes need to be cooled slowly to avoid thermal stress cracking. By atomizing water or gas (such as compressed air) to form tiny droplets or mists, the cooling rate can be precisely controlled, reducing local temperature differences and preventing structural defects in the glass tube caused by sudden cooling or heating.

[0003] When spraying liquid onto the surface of a glass tube, traditional methods mostly involve using three nozzles arranged in a 120-degree array to atomize the liquid. This method has the following problems:

[0004] Uneven spraying: The atomized liquid is not evenly distributed on the surface of the glass tube, resulting in inconsistent coating thickness and affecting product performance (such as optical transmittance and conductivity).

[0005] Uncontrollable droplet size: Traditional nozzles may produce droplets that are too large or too small, resulting in particles, ripples, or uneven drying of the coating.

[0006] Airflow disturbance effects: High-speed airflow may cause the atomized liquid to deviate from the target area, resulting in waste or environmental pollution.

[0007] Therefore, there is an urgent need to design a glass tube atomizing device to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this invention is to provide a glass tube atomizing device that has the advantage of uniformly spraying the atomized liquid onto the glass tube, thus solving the problems mentioned in the background art.

[0009] To achieve the above objectives, the specific technical solution of the glass tube atomizing device of this utility model is as follows:

[0010] A glass tube atomizing device includes an atomizing box through which a glass tube passes to spray atomized liquid. The atomizing box is equipped with a nozzle that can spray atomized liquid. The atomizing box is also equipped with a flow equalization component. The atomized liquid sprayed from the nozzle is evenly distributed by the flow equalization component and then sprayed onto the glass tube. The flow equalization component can rotate around the glass tube to further evenly spray the atomized liquid onto the glass tube.

[0011] Furthermore, the flow equalization assembly includes a flow equalization ring, with a central cavity through which the glass tube passes, and multiple flow equalization holes are formed on the flow equalization ring.

[0012] Furthermore, the flow equalization orifices are hexagonal and have multiple rows, with the same number of orifices in each row, and each pair of adjacent rows of orifices are arranged in an alternating pattern.

[0013] Furthermore, a baffle group is provided inside the flow equalization hole, which divides the flow equalization hole into multiple baffles, making the cross-sectional area distribution of the airflow channel more uniform.

[0014] Furthermore, the baffle assembly includes three baffles, the central portions of which are connected to each other, and the angles between the three baffles are the same, so as to divide the flow equalization orifice into six orifices.

[0015] Furthermore, the two ends of each baffle are connected to the inner corners corresponding to the flow equalization holes.

[0016] Furthermore, the two ends of each baffle are connected to the middle of the corresponding side of the flow equalization hole.

[0017] Furthermore, a support plate is fixedly connected inside the atomizing box, and a rotating groove is opened on the support plate. A retaining ring is fixedly connected to the flow equalization ring, and the flow equalization ring is rotatably connected to the rotating groove on the support plate through the retaining ring.

[0018] Furthermore, the support plate has through holes through which the glass tube passes.

[0019] Furthermore, a toothed ring is fixedly connected to the end of the flow equalization ring away from the retaining ring. The toothed ring meshes with a gear, and a rotating shaft is fixedly connected to the gear. The rotating shaft is driven to rotate by a power source.

[0020] This invention has the following advantages: the rotation of the flow equalization ring enables the atomized liquid to dynamically cover the entire circumference, eliminating the unidirectional deposition effect. At the same time, the rotation of the flow equalization ring compensates for local flow deviations. The rotational motion can be automatically compensated by the time averaging effect, making the overall coating more uniform. It also self-adjusts the coverage range. The centrifugal force generated by the rotation can cause the atomized droplets to diffuse outwards, adapting to glass tubes of different diameters without the need to adjust the nozzle distance.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0029] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a glass tube atomizing device.

[0030] Most existing technologies use three nozzles arranged in a 120-degree arc to spray liquid onto a glass tube, which has the following problems:

[0031] Uneven spraying: The atomized liquid is not evenly distributed on the surface of the glass tube, resulting in inconsistent coating thickness and affecting product performance (such as optical transmittance and conductivity).

[0032] Uncontrollable droplet size: Traditional nozzles may produce droplets that are too large or too small, resulting in particles, ripples, or uneven drying of the coating.

[0033] Airflow disturbance effects: High-speed airflow may cause the atomized liquid to deviate from the target area, resulting in waste or environmental pollution.

[0034] Therefore, this glass tube atomizing device includes an atomizing box 3. The glass tube 1 is conveyed through the atomizing box 3 by the graphite wheel assembly 2 to spray atomized liquid. The atomizing box 3 is equipped with a nozzle 31, which can spray atomized liquid. The atomizing box 3 is equipped with a flow equalization component 32. The atomized liquid sprayed by the nozzle 31 is evenly distributed by the flow equalization component 32 and then sprayed onto the glass tube 1. The flow equalization component 32 can rotate around the glass tube 1 to further evenly spray the atomized liquid onto the glass tube 1.

[0035] By setting up the atomizing box 3, the airflow inside the box undergoes a laminar or vortex design to ensure that the atomized liquid evenly covers the surface of the glass tube 1, reducing spray dead corners. At the same time, the atomizing box 3 can collect excess atomized liquid, reducing evaporation waste and environmental pollution.

[0036] The laminar or vortex design in the atomizing box 3 is existing technology and is well known to those skilled in the art; therefore, this utility model will not elaborate further.

[0037] Preferably, the two side panels of the atomizing box 3 are glass plates, through which the atomization situation inside the atomizing box 3 can be observed. In other embodiments of this utility model, other plates may be used, as long as the atomization situation inside the atomizing box 3 can be observed.

[0038] By setting the flow equalization component 32 to be rotatable, directional deposition is eliminated. During static spraying, the fixed position of the nozzle 31 and the flow equalization hole 322 will cause the coating on the glass tube surface to appear as "stripes" and uneven. The rotation of the flow equalization ring 321 allows the atomized liquid to dynamically cover the entire circumference, eliminating the unidirectional deposition effect. At the same time, the rotation of the flow equalization ring 321 compensates for local flow deviations. Even if there are slight flow differences in a single flow equalization hole 322, the rotational motion can automatically compensate through the time averaging effect, making the overall coating more uniform and self-adjusting the coverage range. The centrifugal force generated by the rotation can cause the atomized droplets to diffuse outward, adapting to glass tubes 1 of different diameters without the need to adjust the distance of the nozzle 31.

[0039] Specifically, the flow equalization component 32 includes a flow equalization ring 321, with a central cavity through which the glass tube 1 passes. The flow equalization ring 321 has uniformly distributed flow equalization holes 322. By setting the flow equalization ring 321 to be annular, corresponding to the shape of the glass tube 1, uniform coating is ensured. Since the flow equalization ring 321 is annular, its inner diameter is smaller than its outer diameter, and thus the inner diameter of the flow equalization holes 322 is smaller than its outer diameter, thereby gradually refining the airflow through the flow equalization holes 322.

[0040] Furthermore, the flow equalization orifice 322 is hexagonal, and the flow equalization orifice 322 is arranged in multiple rows, with the same number of flow equalization orifices 322 in each row. Each pair of adjacent rows of flow equalization orifices 322 are arranged in an alternating pattern. The hexagonal shape of the flow equalization orifice 322 and the six-fold rotational symmetry of the hexagon make the airflow more isotropic, reduce directional bias, and avoid the "jet effect" caused by circular orifices or the corner vortices of square orifices.

[0041] Furthermore, a baffle group 323 is provided inside the flow equalization hole 322. The baffle group 323 divides the flow equalization hole 322 into multiple baffles, making the cross-sectional area distribution of the airflow channel more uniform. This avoids the local turbulence caused by uneven flow velocity within the flow equalization hole 322 when there is only the flow equalization hole 322. At the same time, the airflow path of each baffle is shorter and symmetrical, reducing boundary layer separation and making the overall flow velocity distribution closer to the ideal state. Moreover, the baffles optimize the droplet distribution. When the airflow passes through the small holes, it accelerates and produces a shearing effect on the droplets, further refining the particle size.

[0042] The baffle assembly 323 includes three baffles, the central parts of which are connected to each other and the angles between the three baffles are the same, so as to divide the flow equalization hole 322 into six holes, making the airflow cross-sectional area distribution more uniform.

[0043] Regarding the connection position between the baffle and the flow equalization hole 322 in the first embodiment, the two ends of each baffle are connected to the corresponding inner corners of the flow equalization hole 322, thereby symmetrically dividing the hexagonal flow equalization hole 322 into six identical fan-shaped holes, which is more conducive to uniform fluid distribution and reduces local eddies or flow deviation. At the same time, the baffles converge at the center point to form a radial support, which has high overall rigidity and strong resistance to deformation. It also conforms to the natural symmetry of the hexagon, further ensuring uniform flow.

[0044] In the second embodiment regarding the connection position of the baffle and the flow equalization hole 322, both ends of each baffle are connected to the middle of the corresponding side of the flow equalization hole 322. The baffle is perpendicular to the side, and the trapezoidal small hole formed is more conducive to flow in a specific direction, while avoiding the problem of central stress concentration.

[0045] Regarding the rotation method of the flow equalization ring 321, a support plate 33 is fixedly connected inside the atomizing box 3. A rotating groove is provided on the support plate 33. A retaining ring 34 is fixedly connected to the flow equalization ring 321. The flow equalization ring 321 is rotatably connected to the rotating groove on the support plate 33 through the retaining ring 34. The retaining ring 34 and the rotating groove ensure that the flow equalization ring 321 can rotate and limit the flow equalization ring 321. In other embodiments of this utility model, the flow equalization ring 321 can also be rotated by other means.

[0046] The support plate 33 has a through hole, through which the glass tube 1 passes through the support plate 33.

[0047] Furthermore, a gear ring 35 is fixedly connected to one end of the flow equalization ring 321 away from the retaining ring 34. The gear ring 35 meshes with a gear 41. A rotating shaft 42 is fixedly connected to the gear 41. The rotating shaft 42 is driven to rotate by a power source 4.

[0048] The preferred power source 4 is an electric motor.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
