Description

Technical Field

[0001] The invention relates to a glass furnace, in particular to a distribution channel of a glass furnace. Background Art

[0002] In response to the market demand for lightweighting, it is necessary to provide solutions for lightweight production in terms of glass temperature regulation. Half of the factors in the molding of a glass bottle depend on the glass temperature regulation, which is equivalent to the pre-molding of the droplets; the other half is determined by the molding process. The premise for reducing the weight of the bottle is that the glass is evenly distributed during the molding process. The distribution channel, as a glass regulation system, is an important part of the glass furnace. The molten glass liquid is further homogenized and cooled in the distribution channel, and then distributed to each feeding channel. Therefore, the design of the distribution channel is crucial to the quality of the glass liquid. Summary of the invention

[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 to the technical problem solved by the present invention 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, 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 entrance area, and the discharge port is connected to the distribution area; the liquid depth of the entrance area is greater than the liquid depth of the distribution area, the entrance 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 present invention are as follows: the present invention sets the depth of the molten glass in the kiln pool in a stepped manner, so that the depth of the molten glass is greater at the entrance, and when the molten glass enters the distribution area from the entrance area, the glass bottle needs to have a climbing process, and the climbing process is utilized to retain impurities in the molten glass at a low place, thereby improving the quality of the molten glass; and the transition bricks adopt an inclined transition, which can slow down the erosion of the molten glass on the bottom of the kiln pool.

[0006] As a further improvement of the above technical solution, the distribution area includes a left area and a right area, the left area and the right area are respectively located on the left and right sides of the inlet area, and the left area and the inlet area are connected by a transition brick. The distribution channel feeds from the middle and then distributes to the left and right sides, so that the glass liquid can be better homogenized in the distribution channel, thereby improving the discharge quality of the glass liquid.

[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 bath 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 feeder channel, the risk of too short a flow path of the glass liquid is reduced, and the optimal temperature at the inlet of the feeder channel is achieved. At the same time, the glass liquid also needs to 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 bath can be adjusted in time.

[0010] As a further improvement of the above technical solution, the kiln bath 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 paving bricks with different heights, the construction of the kiln bath is facilitated. When the paving bricks are eroded, only the paving bricks need to be replaced, which extends the service life of the kiln bath.

[0011] As a further improvement of the above technical solution, the transition brick includes a first stepped surface and a second stepped surface. The first paving brick is lapped on the first stepped surface, and the second paving brick is lapped on the second stepped 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 stepped surface, and the second gap is located on the second stepped surface. By using the two stepped 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 stepped 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, 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 the height 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 coming 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 divide 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 the production needs.

[0013] As a further improvement of the above technical solution, the arch area includes a temperature control system, which includes a cooling air duct, a smoke exhaust outlet, a heating gun and a temperature measurement module, and a fan is provided in the cooling air duct. In the arch area, direct air cooling, indirect cooling and heating mechanisms are configured, so that the temperature control of this area can be more accurate and efficient.

[0014] As a further improvement of the above technical solution, the upper space structure is also provided with a laser liquid level meter. The laser liquid level meter is used to monitor the liquid level in the distribution channel. When the liquid level fluctuates greatly, human intervention is required to ensure the stability of the liquid level of the glass liquid, thereby ensuring the quality of the glass liquid.

At the same time, the various technical features in the invention can be combined interchangeably without conflicting with each other.

[0021] When producing glass products, glass raw materials are mixed into batch materials in a certain proportion, melted into glass liquid in the kiln, and passed through the flow hole, successively entering the distribution channel and the supply channel, and finally reaching the molding machine. During the flow of glass liquid, the temperature changes due to the channel structure, flow rate changes and other reasons, resulting in streaks, which seriously affect the appearance quality of the product. At the same time, the change in glass temperature causes factors such as crystallization, resulting in inconsistent glass density and composition, and it is very easy to reduce the physical and chemical performance indicators. At the same time, because the temperature of the glass liquid is high when it flows out of the flow hole, there are also many impurities. Usually, the impurities in the glass liquid coming out of the flow hole are basically precipitated at the bottom of the glass liquid. In addition, since different materials require different molding temperatures, according to the temperature requirements of the molding process, the distribution channel needs to have the ability to cool down and heat up.

[0022] To this end, the present invention provides an improved distribution channel, so that the molten glass can be better homogenized and temperature controlled in the distribution channel, thereby improving the quality of the molten glass entering the molding machine and improving the molding quality of the glass products.

[0023] Reference Figure 1 to Figure 6 A distribution channel of a glass kiln includes 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 includes 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 includes a feed port 101 and a plurality of discharge ports 102, wherein the feed port 101 is connected to the inlet area 110, and the discharge port 102 is 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, and the inlet area 110 and the distribution area 120 are connected by a transition brick 300, and the transition brick 300 includes an inclined surface.

[0024] The feed port 101 is connected to the flow hole of the kiln. After the glass liquid flows out of the flow hole, it reaches the inlet area 110 from the feed port 101, and then flows to the left and right sides from the inlet area 110 and enters the distribution area 120. The glass liquid flows, is homogenized, and temperature-controlled in the inlet area 110 and the distribution area 120, and finally enters the feed channel from the discharge port 102, and finally enters the molding machine. As mentioned above, since impurities in the glass liquid are mainly concentrated at the bottom, in order to reduce the impurities from finally entering the molding machine, the impurities need to be precipitated in the inlet area. To this end, in the present invention, the liquid depth of the inlet area 110 is set to be greater than the liquid depth of the distribution area 120. After the glass liquid reaches the inlet area 110 from the feed port 101, a precipitate will be formed in the inlet area 110, and then the glass liquid will diffuse from the inlet area 110 to the distribution area 120. Since the liquid depth of the inlet area 110 is greater than the liquid depth of the distribution area 120, the glass liquid will have a climbing process when entering the distribution area 120. Since the specific gravity of the impurities is greater than the specific gravity of the glass liquid, they will be deposited at the bottom of the glass liquid. During the climbing process, most of the impurities will be blocked on the transition bricks, so that the impurities can be retained at the bottom of the inlet area 110. Since the impurities do not enter the distribution area 120, the quality of the glass liquid flowing out of the discharge port 102 can be improved. In addition, in order to reduce the dead angle erosion of the impurities on the transition bricks 300, the transition bricks 300 are provided with a slope transition. By cleverly setting the slope of the slope, a good transition effect can be achieved, slowing down the erosion of the glass liquid on the bottom of the kiln pool.

[0025] 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 the inlet area 110 as the middle boundary. The feed port 101 is located in the middle of the inlet area 110 and in front of the inlet area 110. The glass liquid enters the inlet area 110 from the feed port 101 from the front to the back from the flow hole. After the glass liquid hits the rear pool wall of the inlet area 110, it is divided to the left and right sides, and then basically evenly flows 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 uniform effect of the glass liquid in the distribution channel can be improved, and the discharge quality of the glass liquid can be improved.

[0026] See also Figure 2 , Figure 3As a further preferred embodiment, the kiln pool 100 includes a kiln bottom structure 130, and a first paving brick 131 is laid on the kiln bottom structure 130 in the entrance area 110; a second paving brick 132 is laid on the kiln bottom structure 130 in the distribution area 120; the installation height of the second paving brick 132 is greater than the installation height of the first paving brick 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 part of the kiln bottom structure 130 is first made, and the foundation part is the same for the entire kiln pool 100, so that it is convenient for construction. In order to achieve the effect of the height difference of the liquid, the present invention lays paving bricks of different installation heights on the base part, and the installation height of the first paving brick 131 in the inlet area 110 is lower than the installation height of the second paving brick 132 in the distribution area 120. At the same time, the first paving brick 131 and the second paving brick 132 are connected by the transition brick 300. The use of two paving bricks of different heights can facilitate the construction of the kiln pool. When the paving bricks are eroded, they only need to be replaced, which prolongs the service life of the kiln pool.

[0027] 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. See FIG. 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 glass liquid 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 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 glass liquid 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.

[0028] At the same time, since the glass liquid in the distribution channel enters from the feed port 101 and then flows out from the discharge port 102, in order to make the glass liquid have a better homogenization effect, it is necessary to optimize the overall residence time of the glass liquid in the distribution channel. Therefore, the distance of each discharge port 102 from the feed port 101 is very important. First, it is necessary to ensure that the glass liquid has sufficient residence time in the distribution channel, but not too long, as too long a time will increase the energy consumption of the kiln. Set the distance between the first discharge port and the feed port as L1, the flow rate of the glass liquid in the kiln tank as V, and the residence time of the glass liquid in the left area as T1, T1 = L1 / V, where 1 hour < T1 < 2 hours. Through experience summary, optimization calculation and experimental verification, setting the residence time of the glass liquid in the distribution channel to 1 - 2 hours is a better solution.

[0029] 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.

[0030] 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 , further as a 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.

[0031] The upper space structure 200 can divide the upper space of the kiln pool 100 into multiple separate spaces by reasonably arranging 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. The upper space of the inlet area 110 of the kiln pool 100 corresponds to the arch area 210, and the arch area 210 adopts a high arch top structure, see Figure 5 The arch area 210 includes a wall structure with an upper space and an arch structure located above the wall structure, and the arch structure is in an arc shape; and the upper space of the distribution area 120 of the kiln pool 100 corresponds to the cover area 220, and the cover area 220 adopts a flat arch structure (or a cover structure), see Figure 6 The cover plate area 220 also includes a wall structure of 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.

[0032] As mentioned above, since the temperature of the molten glass 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 higher space and thus a better cooling effect. The distribution area 120 located downstream of the molten glass has an upper space corresponding to the cover area 220. This area adopts a cover structure with a flat crown structure, which is not only safer and more stable, but the shorter space above the molten glass can help reduce the heat dissipation of the air and achieve an energy-saving effect.

[0033] As a further preferred embodiment, the crown area 210 includes a temperature control system, which includes a cooling air duct, a smoke exhaust outlet, a heating gun, and a temperature measurement module, and a fan is provided in the cooling air duct. In the crown area 210, direct air cooling, indirect cooling, and heating mechanisms are configured, so that the temperature control of this area can be more accurate and efficient.

[0034] It can be understood that the cover plate area 220 is also provided with a smoke exhaust outlet, a heating gun and a temperature measuring module; thus, each area is provided with an independent heater and a heat dissipation channel, and each area can be individually controlled and temperature-adjusted according to the usage. As mentioned above, since the glass liquid temperature in the inlet area 110 is the highest, in order to quickly control the glass liquid in this area at a suitable temperature, a direct air cooling device will be configured on the vent area 210. As for the downstream cover plate area 220, it is only necessary to reserve a chimney for the smoke exhaust outlet, and the temperature adjustment requirements can be met by adjusting the opening size of the chimney, thereby reducing the production cost of the distribution channel.

[0035] 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 greatly, human intervention is required to ensure the stability of the liquid level of the glass liquid, thereby ensuring the quality of the glass liquid. The preferred embodiments of the present invention are specifically described above, 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 invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
