Abstract
Description
Technical Field
[0001] The utility model relates to a glass kiln, in particular to a distribution channel of a glass kiln. Background Art
[0002] Meeting market demand for lightweighting requires solutions for glass temperature regulation in lightweight production. Half of the process of forming a glass bottle depends on glass temperature regulation, which is equivalent to the pre-forming of the gob; the other half is determined by the molding process. Reducing bottle weight requires uniform distribution of the glass during the molding process. The distribution manifold, as the glass conditioning system, is a crucial component of the glass furnace. The molten glass is further homogenized and cooled in the distribution manifold before being distributed to the various feed channels. Therefore, the design of the distribution manifold is crucial to the quality of the molten glass. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a distribution channel to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve its technical problems is: a distribution channel of a glass kiln, including a kiln pool and an upper space structure, the upper space structure is located above the kiln pool, the kiln pool includes an entrance area and a distribution area, the entrance area is located in the middle of the kiln pool, and the distribution area is located on both sides of the kiln pool, the kiln pool also includes a feed port and several discharge ports, the feed port is connected to the inlet area, and the discharge port is connected to the distribution area; the liquid depth of the inlet area is greater than the liquid depth of the distribution area, the inlet area and the distribution area are connected by a transition brick, and the transition brick includes an inclined surface.
[0005] The beneficial effects of the utility model are as follows: the utility model sets the depth of the glass liquid in the kiln pool in a stepped manner, so that the depth of the glass liquid is greater at the entrance, and when the glass liquid enters the distribution area from the entrance area, the glass bottles need to go through a climbing process, and the climbing process is utilized to leave impurities in the glass liquid at a low place, thereby improving the quality of the glass liquid; and the transition bricks adopt an inclined transition, which can slow down the erosion of the glass liquid on the bottom of the kiln pool.
[0006] As a further improvement to the above technical solution, the distribution area includes a left area and a right area, located on the left and right sides of the inlet area, respectively, and connected to the inlet area by a transition brick. By feeding from the center and then distributing to the left and right sides, the distribution channel can achieve better homogenization of the molten glass in the distribution channel, thereby improving the discharge quality of the molten glass.
[0007] As a further improvement of the above technical solution, a first discharge port is included in the left region. The distance between the first discharge port and the feed port is L1, the flow rate of the glass liquid in the kiln tank is V, and the residence time of the glass liquid in the left region is T1, where T1 = L1 / V, and 1 hour < T1 < 2 hours. By optimizing the distance of the supply channel, the risk of too short flow path of the glass liquid is reduced, and the optimal temperature at the inlet of the supply channel is achieved. At the same time, the glass liquid should also have sufficient residence time in the distribution channel to achieve a better homogenization effect.
[0008] As a further improvement of the above technical solution, the right region is mirror-symmetrical to the left region with the feed port as the center.
[0009] As a further improvement of the above technical solution, observation ports are provided on both the inlet region and the distribution region. By providing the observation ports, it is convenient to observe the operating conditions of each region inside the distribution channel. If any abnormality occurs, the kiln tank can be adjusted in time.
[0010] As a further improvement of the above technical solution, the kiln tank includes a kiln bottom structure. On the inlet region, a first paving brick is laid on the kiln bottom structure; on the distribution region, a second paving brick is laid on the kiln bottom structure; the installation height of the second paving brick is greater than that of the first paving brick; one side of the transition brick is connected to the first paving brick and the other side is connected to the second paving brick. By using two kinds of paving bricks with different heights, the construction of the kiln tank is facilitated. When the paving bricks are eroded, only the paving bricks need to be replaced, extending the service life of the kiln tank.
[0011] As a further improvement of the above technical solution, the transition brick includes a first step surface and a second step surface. The first paving brick overlaps on the first step surface, and the second paving brick overlaps on the second step surface. A first gap is formed between the first paving brick and the transition brick, and a second gap is formed between the second paving brick and the transition brick. The first gap is located on the first step surface, and the second gap is located on the second step surface. By using the two step surfaces and the two gaps, not only can the installation of the paving bricks be made more convenient and reliable, but also expansion joints can be reserved to ensure that the brick surface can expand in the horizontal direction. Moreover, a closed surface is formed in the vertical direction by the step surfaces to prevent the glass liquid from penetrating into the kiln bottom.
[0012] As a further improvement of the above technical solution, the upper space structure includes a crown area and a cover area, wherein the crown area is located above the inlet area, and the cover area is located above the distribution area; the height of the crown area is greater than that of the cover area, and a partition device is provided between the crown area and the cover area. The inlet area adopts a crown structure with a higher space, which helps to cool down the high-temperature glass liquid entering from the inlet; and the cover structure adopted in the downstream distribution area can reduce the heat dissipation of the space and play a role in energy saving; at the same time, the crown area and the cover area are separated by a partition device to separate the kiln pool into multiple independent spaces for separate temperature control, so that the temperature and air pressure between the various areas will not interfere with each other, and the temperature at each outlet is guaranteed to be as uniform as possible to meet production needs.
[0013] As a further improvement to the above technical solution, the hood area includes a temperature control system comprising a cooling duct, a smoke exhaust outlet, a heating gun, and a temperature measurement module. A fan is installed in the cooling duct. Direct air cooling, indirect cooling, and heating mechanisms are deployed in the hood area, enabling more precise and efficient temperature control.
[0014] As a further improvement to the above technical solution, the upper space structure is further provided with a laser level meter, which monitors the liquid level in the distribution channel. When the liquid level fluctuates significantly, manual intervention is required to ensure the stability of the liquid glass level, thereby ensuring the quality of the liquid glass.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

The preferred embodiments of the present invention are shown in the drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0026] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.
[0027] In the description of this utility model, unless otherwise expressly defined, terms such as "install," "connect," and "set" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meanings of these terms in this utility model based on the specific content of the technical solution. Furthermore, the various technical features of this invention may be combined interchangeably as long as they do not conflict with each other.
[0028] When producing glass products, raw glass materials are mixed in a specific proportion to form a batch. This is then melted in a furnace to form molten glass. The glass then flows through a flow channel, into a distribution channel, a feed channel, and finally into the molding machine. Temperature fluctuations during the flow of the molten glass, caused by factors such as the channel structure and flow rate, can cause streaks and severely impact the product's appearance. Furthermore, these temperature fluctuations can lead to factors such as crystallization, resulting in inconsistent glass density and composition, and a significant reduction in physical and chemical properties. Furthermore, because the molten glass is hotter when it exits the flow channel, it also contains a high concentration of impurities. These impurities typically settle to the bottom of the molten glass. Furthermore, because different molding temperatures are required for different material colors, the distribution channel must be capable of both cooling and heating, depending on the temperature requirements of the molding process.
[0029] To this end, the utility model provides an improved distribution channel, so that the glass liquid can be better homogenized and temperature-controlled in the distribution channel, thereby improving the quality of the glass liquid entering the molding machine and improving the molding quality of the glass products.
[0030] Reference Figures 1 to 6 A distribution channel of a glass kiln comprises a kiln pool 100 and an upper space structure 200, wherein the upper space structure 200 is located above the kiln pool 100. The kiln pool 100 comprises an inlet area 110 and a distribution area 120, wherein the inlet area 110 is located in the middle of the kiln pool 100 and the distribution area 120 is located on the left and right sides of the kiln pool 100. The kiln pool 100 also comprises a feed port 101 and several discharge ports 102, wherein the feed port 101 is connected to the inlet area 110, and the discharge ports 102 are connected to the distribution area 120. The liquid depth of the inlet area 110 is greater than the liquid depth of the distribution area 120. The inlet area 110 and the distribution area 120 are connected by a transition brick 300, wherein the transition brick 300 comprises an inclined surface.
[0031] The feed port 101 is connected to the furnace's flow hole. After the molten glass flows out of the flow hole, it reaches the inlet area 110 through the feed port 101. From there, it flows to the left and right, entering the distribution area 120. The molten glass flows, is homogenized, and has its temperature controlled in these two areas. Finally, it enters the feed channel through the discharge port 102 and enters the molding machine. As previously mentioned, impurities in the molten glass are primarily concentrated at the bottom. To reduce the amount of impurities that enter the molding machine, they need to be deposited in the inlet area. To this end, in the present invention, the liquid depth of inlet region 110 is set greater than that of distribution region 120. After the molten glass reaches inlet region 110 from feed port 101, it forms a sediment there. The molten glass then flows from inlet region 110 into distribution region 120. Because the liquid depth of inlet region 110 is greater than that of distribution region 120, the molten glass experiences a sloped transition as it enters distribution region 120. Since impurities have a greater specific gravity than the molten glass, they settle at the bottom of the molten glass. During this sloped transition, the vast majority of impurities are blocked by the transition bricks, allowing them to remain at the bottom of inlet region 110. Since impurities are prevented from entering distribution region 120, the quality of the molten glass flowing from discharge port 102 is improved. Furthermore, to reduce impurities from eroding the transition bricks 300 in dead corners, the transition bricks 300 are designed with a sloped transition. By cleverly setting the slope of the slope, a good transition effect is achieved, mitigating erosion of the molten glass on the bottom of the kiln tank.
[0032] See also Figure 1 It can be seen that the inlet area 110 is located in the middle of the kiln pool 100, and the distribution area 120 is divided into two parts, namely the left area and the right area. The left and right areas are basically mirror-symmetrical with each other with the inlet area 110 as the midpoint. The feed port 101 is located in the middle of the inlet area 110 and in front of the inlet area 110. The molten glass enters the inlet area 110 from the feed port 101 from the front to the back through the flow hole. After the molten glass hits the rear wall of the inlet area 110, it is divided to the left and right sides and then flows basically evenly to the distribution areas 120 on the left and right sides. By symmetrically arranging the distribution areas 120 on both sides of the inlet area 110, the uniformity of the molten glass in the distribution channel can be improved, and the discharge quality of the molten glass can be improved.
[0033] See also Figure 2 、 Figure 3As a further preferred embodiment, the kiln pool 100 includes a kiln bottom structure 130. First paving bricks 131 are laid on the kiln bottom structure 130 in the entrance area 110. Second paving bricks 132 are laid on the kiln bottom structure 130 in the distribution area 120. The second paving bricks 132 are installed at a greater height than the first paving bricks 131. One side of the transition brick 300 is connected to the first paving brick 131, and the other side is connected to the second paving brick 132. When constructing the kiln pool 100, the foundation of the kiln bottom structure 130 is first constructed. This foundation is the same for the entire kiln pool 100, facilitating construction. To create a height difference in the liquid level, the present invention employs paving bricks of varying heights on the base. The first paving brick 131 in the inlet area 110 is installed at a lower height than the second paving brick 132 in the distribution area 120. A transition brick 300 connects the first and second paving bricks 131, 132. Using two different paving brick heights facilitates kiln construction. When eroded, these bricks can simply be replaced, extending the kiln's service life.
[0034] In addition, since the glass liquid will pass through the first paving brick 131, the transition brick 300, and the second paving brick 132 in the working process, in order to improve the firmness of the installation, the transition brick 300 needs to play a good supporting role. To this end, the transition brick 300 includes a first step surface 310 and a second step surface 320. The first paving brick 131 overlaps the first step surface 310, and the second paving brick 132 overlaps the second step surface 320. At the same time, a first gap 301 is formed between the first paving brick 131 and the transition brick 300, and a second gap 302 is formed between the second paving brick 132 and the transition brick 300. The first gap 301 is located on the first step surface 310, and the second gap 302 is located on the second step surface 320. Figure 3, the first step surface 310 is located inside the transition brick 300, and the second step surface 320 is located outside the transition brick 300. The inclined surface is located between the two step surfaces. During construction, the edge of the first paving brick 131 is placed on the first step surface 310, and the edge of the second paving brick 132 is placed on the second step surface 320, so that the upper surface of the first paving brick 131 is connected to the bottom of the inclined surface, and the upper surface of the second paving brick 132 is connected to the top of the inclined surface. At the same time, there is a relatively obvious gap between the first paving brick 131 and the second paving brick 132 and the transition brick 300 in the horizontal direction, and this gap is used as a reserved expansion joint. Since during the working process, both the first paving brick 131 and the second paving brick 132 will be affected by the high temperature of the molten glass and thus expand, by reserving the first gap 301 and the second gap 302, the structural strength of the kiln tank can be improved, and the situation of cracking at the bottom of the kiln tank caused by the inconsistent expansion of the first paving brick 131 and the second paving brick 132 due to uneven heat absorption can be avoided. At the same time, by using the first step surface 310 and the second step surface 320, a good seal is formed between the transition brick and the paving brick, effectively preventing the molten glass from flowing from the gap to the foundation part of the kiln tank and causing erosion to the foundation part of the kiln tank, thereby improving the service life of the kiln tank.
[0035] At the same time, since the molten glass enters from the feed inlet 101 and then flows out from the discharge outlet 102 in the distribution channel, in order to make the molten glass have a better homogenization effect, it is necessary to optimize the overall residence time of the molten glass in the distribution channel. Therefore, the distance of each discharge outlet 1'02 from the feed inlet 101 is very important. First, it must be ensured that the molten glass has sufficient residence time in the distribution channel, and the time cannot be too long, because too long time will increase the energy consumption of the kiln furnace. Set the distance between the first discharge outlet and the feed inlet to be L1, the flow rate of the molten glass in the kiln tank to be V, and the residence time of the molten glass in the left area to be T1, T1 = L1 / V, where 1 hour < T1 < 2 hours. Through experience summary, optimization calculation and experimental verification, setting the residence time of the molten glass in the distribution channel to be 1 - 2 hours is a better solution.
[0036] See Figure 1 , further as a preferred embodiment, observation ports 103 are provided on both the inlet area 110 and the distribution area 120. By providing the observation ports 103, it is convenient to observe the operating conditions of each area inside the distribution channel. If any abnormality occurs, the kiln tank can be adjusted in time.
[0037] As mentioned above, in order to improve the quality of the glass liquid, the glass needs to be temperature controlled in the distribution channel. The temperature control of the glass liquid in the distribution channel is mainly achieved by the upper space structure 200 of the distribution channel. At the same time, in order to achieve a stable temperature control effect, the upper space of the glass liquid is usually divided into multiple separate spaces to facilitate separate heating control. For details, see Figure 4 - Figure 6 As a further preferred embodiment, the upper space structure 200 includes a crown area 210 and a cover area 220, the crown area 210 is located above the entrance area 110, and the cover area 220 is located above the distribution area 120; the height of the crown area 210 is greater than the height of the cover area 220, and a partition device 230 is also provided between the crown area 210 and the cover area 220.
[0038] The upper space structure 200 can divide the upper space of the kiln pool 100 into multiple separate spaces by properly setting the partition device 230, so that the temperature and air pressure of each space do not interfere with each other. Figure 4 The upper space of the entire distribution channel is divided into two cover areas 220 and one arch area 210 by two partition devices 230. Among them, the upper space of the inlet area 110 of the kiln pool 100 corresponds to the arch area 210, which adopts a high arch top structure. Figure 5 The arch area 210 includes a wall structure with an upper space and a arch structure located above the wall structure. The arch structure is in an arc shape. The upper space of the distribution area 120 of the kiln pool 100 corresponds to the cover area 220. The cover area 220 adopts a flat arch structure (or a cover structure). Figure 6 The cover plate area 220 also includes a wall structure in the upper space, but a cover plate structure is used on the upper part of the wall structure, and the spatial height of the cover plate structure is smaller than the high arch top structure in the arch area 210.
[0039] As mentioned above, since the temperature of the glass liquid is relatively high when it enters the inlet area 110, it generally needs to be cooled. The crown area with a high crown top structure has a better cooling effect due to its higher space. The distribution area 120 located downstream of the glass liquid has an upper space corresponding to the cover area 220. This area adopts a flat crown structure cover structure, which is not only safer and more stable, but the lower space above the glass liquid can help reduce the heat dissipation of the air and achieve energy-saving effects.
[0040] As a further preferred embodiment, the crown area 210 includes a temperature control system comprising a cooling duct, a smoke exhaust outlet, a heating gun, and a temperature measurement module. A fan is provided within the cooling duct. By configuring the crown area 210 with direct air cooling, indirect cooling, and heating mechanisms, the temperature control within the crown area can be more precise and efficient.
[0041] As will be appreciated, the cover plate area 220 is also equipped with a smoke exhaust outlet, a heating gun, and a temperature measurement module; thus, each area is equipped with an independent heater and heat dissipation channel, allowing for individual control and temperature adjustment based on usage. As previously mentioned, since the glass liquid in the inlet area 110 is at its highest temperature, a direct air cooling device is installed in the inlet area 210 to quickly control the glass liquid in this area to an appropriate temperature. For the downstream cover plate area 220, only a chimney is required for the smoke exhaust outlet. By adjusting the chimney opening size, the temperature control requirements can be met, reducing the production cost of the distribution channel.
[0042] As a further preferred embodiment, the upper space structure is further provided with a laser level meter, which monitors the liquid level in the distribution channel. When the liquid level fluctuates significantly, manual intervention is required to ensure the stability of the liquid glass level, thereby ensuring the quality of the liquid glass.
[0043] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
