Description

Technical Field

[0001] The invention relates to the field of melting furnaces, in particular to a glass melting furnace. Background Art

[0002] A glass melting furnace is a device for melting glass. The melting part of the glass melting furnace consists of a glass melting pool, front and rear gables, and a large arch. In the process of making molten glass, the melting part of the glass melting furnace is in an environment of high temperature, alkaline steam, and flying materials for a long time. The surface of the large arch refractory material will be chemically eroded to form a low eutectic. With long-term erosion or temperature fluctuations, the erosion products (arch droplets) on the surface of the large arch refractory material will flow down along the surface of the brick material, and part of them will slowly flow down along the rear gable until they fall onto the glass liquid in the glass melting pool, causing defects such as stones, nodules, and glass tendons in the manufactured glass, thus affecting the quality of the glass.

[0003] In addition, the melting part built in a cold state needs to be baked under a strict heating system, and the temperature rises from room temperature to above 1500℃. During the heating process, the refractory materials in various parts of the melting part expand to the surroundings. In order to prevent the expansion of the refractory materials in various parts of the melting part during the heating process, they are squeezed and crushed, and appropriate expansion joints need to be reserved according to the expansion coefficient of each refractory material. After the melting part is heated and baked, the expansion joints of the arch and gable cannot be completely closed. In the process of making glass liquid, with the continuous scouring and erosion of the internal flame and alkaline gas, the mud and brick materials at the expansion joints of the arch and gable are also easily burned or eroded. When the impurities generated by the burning or erosion of the mud and brick materials flow along the gable to the glass liquid in the glass melting pool, it will cause defects such as stones, nodules, and glass tendons in the manufactured glass, thereby affecting the quality of the glass.

[0004] At present, there are no effective measures to prevent the problem of crown drips flowing along the gable to the molten glass, and impurities generated at the gable and large crown expansion joints flowing along the gable to the molten glass. However, the resulting quality defects will affect the yield of glass products. Summary of the invention

[0005] Based on this, it is necessary to provide a glass melting furnace to address the problem of low yield of glass products.

[0006] A glass melting furnace comprises a glass melting part, wherein the glass melting part comprises a melting pool, a large arch and four walls connected to the large arch, wherein:

The rear gable wall is provided with at least one first flow-blocking brick layer protruding along the circumference of the rear gable wall on one side close to the feeding port.

[0009] In the specific process of manufacturing molten glass in the above-mentioned glass melting furnace, the glass melting part is in an environment of high temperature, alkaline steam and flying materials for a long time. On the one hand, this environment causes chemical corrosion on the surface of the large arch refractory material to form a low eutectic. On the other hand, the mud and brick materials at the expansion joints reserved in the large arch and gable according to the expansion coefficient of each refractory material are also easily burned or corroded. The present invention provides at least one first baffle brick layer protruding along the circumference of the rear gable on one side of the rear gable close to the feeding port, so that the low eutectic formed on the surface of the large arch refractory material and the impurities generated at the expansion joints are gathered in the first baffle brick layer when they flow along the rear gable toward the ground, thereby preventing the low eutectic and impurities from flowing along the rear gable into the molten glass, which may cause defects such as stones, nodules and glass ribs in the manufactured glass, thereby improving the yield of glass products. In addition, the design and construction of the first baffle brick layer provided on the rear gable is simple and low in cost, and can effectively solve the problem of eutectic and impurities flowing along the gable into the molten glass.

[0010] In one of the embodiments, the orthographic projection of the first baffle brick layer on the rear gable is a "human" shape, and the tip of the first baffle brick layer faces the arch.

[0011] In one embodiment, the first baffle brick layer includes a plurality of first baffle bricks, and two adjacent first baffle bricks are overlapped.

[0012] In one embodiment, the overlapping width of two adjacent first baffle bricks is in the range of 20 mm to 30 mm.

[0013] In one embodiment, there are two first baffle brick layers, which are vertically opposite to each other, and a height of an upper first baffle brick layer protruding from the rear gable is less than a height of a lower first baffle brick layer protruding from the rear gable.

[0015] In one of the embodiments, the vertical distance between the upper first baffle brick layer and the lower first baffle brick layer ranges from 600 mm to 1500 mm.

[0016] In one embodiment, it further comprises a cooling portion and a connecting portion, wherein the connecting portion comprises a small arch, a narrow channel and at least one partition wall, wherein:

[0017] The cooling part is spaced apart from the glass melting part and is located on a side of the rear gable away from the feeding port, and the cooling part covers at least a portion of the connecting part;

[0018] An arched hole is opened on the rear gable, and the small arch is arranged on the edge of the rear gable close to the arched hole;

[0019] One end of the narrow channel is connected to the molten pool, and the other end of the narrow channel passes through the arched hole and is connected to the cooling part;

[0020] At least one of the partition walls is arranged in the small arch along the arrangement direction of the hanging wall and the rear gable;

[0034] The technical solution provided by the embodiments of the present invention is described below in conjunction with the accompanying drawings.

[0035] like Figure 1 As shown, an embodiment of the present invention provides a glass melting furnace 10 for melting and manufacturing glass. The glass melting furnace 10 includes a glass melting part, which is used to heat the batch material at a high temperature to form a uniform, pure, transparent glass liquid that meets the molding requirements. The glass melting part includes a melting pool, a large arch 100, and four walls connected to the large arch 100. In the specific setting, the large arch 100 is generally built with silica bricks, wherein:

[0036] The large arch 100 and the four walls form a melting space, and the melting pool is located in the melting space, and the melting pool is used to place the glass liquid;

[0037] The four walls include relative hanging walls and a rear gable 200. A feeding port is provided on the hanging wall. On one side of the rear gable 200 close to the feeding port, at least one first baffle brick layer 210 protruding circumferentially along the rear gable 200 is provided. In specific settings, the wall connected to the rear gable 200 among the four walls is called a breast wall. The number of layers of the first baffle brick layer 210 can be two, three, four or more.

[0038] In the process of manufacturing glass liquid, the glass melting part of the glass melting furnace 10 is in a high temperature, alkaline steam and flying material environment for a long time. On the one hand, this environment causes the surface of the refractory material of the arch 100 to be chemically corroded to form a low eutectic. On the other hand, the mud and brick materials at the expansion joints reserved in the arch 100 and the gable according to the expansion coefficient of each refractory material are also easily burned or corroded. In the present invention, at least one first baffle brick layer 210 protruding along the circumference of the rear gable 200 is provided on one side of the rear gable 200 close to the feeding port. The low eutectic formed on the surface of the refractory material of the large arch 100 and the impurities generated at the expansion joints are gathered in the first baffle brick layer 210 when flowing along the rear gable 200 toward the ground, so as to prevent the low eutectic and impurities from flowing into the molten glass along the rear gable 200 and causing defects such as stones and nodules in the manufactured glass, thereby improving the yield of glass products. In addition, the design and construction of setting the first baffle brick layer 210 on the rear gable 200 is simple and low in cost, which can effectively solve the problem of eutectic and impurities flowing into the molten glass along the rear gable 200.

[0039] In order to make better use of the first baffle brick layer 210, in a preferred embodiment, the orthographic projection of the first baffle brick layer 210 on the rear gable 200 is a "human" shape, and the tip of the first baffle brick layer 210 faces the arch 100. Through the above arrangement, after the eutectic and impurities flow along the rear gable 200 to the first baffle brick layer 210, the eutectic and impurities will slowly flow down from the tip of the first baffle brick layer 210 to both sides of the tip, flow along both sides of the tip to the joint between the rear gable 200 and the breast wall, and then flow along the joint to the ground, which more effectively solves the problem of the eutectic and impurities flowing to the glass liquid along the rear gable 200, and improves the yield rate of glass products.

[0040] In order to enable the first baffle brick layer 210 to better bear the low eutectic formed on the surface of the large arch 100 refractory material and the impurities generated at the expansion joint, a preferred implementation manner is that the first baffle brick layer 210 includes a plurality of first baffle bricks 211, and two adjacent first baffle bricks 211 are arranged in an overlapping manner. In the specific arrangement, in addition to using low-cost silicon bricks, the first baffle bricks 211 can also use corundum bricks, white jade bricks, zircon bricks, etc. with good corrosion resistance. Through the above-mentioned arrangement, when the low eutectic formed on the surface of the refractory material of the large arch 100 and the impurities generated at the expansion joints flow along the rear gable 200 to the first baffle brick layer 210, the first baffle bricks 211 overlapping each other can prevent the low eutectic and impurities from leaking into the molten glass from the brick joints between two adjacent first baffle bricks 211, thereby making the low eutectic formed on the surface of the refractory material of the large arch 100 and the impurities generated at the expansion joints better gathered in the first baffle brick layer 210, thereby better ensuring the effectiveness of the first baffle brick layer 210 in preventing the low eutectic and impurities from flowing into the molten glass.

[0041] In order to better prevent the low eutectic and impurities accumulated in the first baffle brick layer 210 from leaking into the glass liquid along the brick joints between the two adjacent first baffle bricks 211, specifically, the overlapping width of the two adjacent first baffle bricks 211 ranges from 20mm to 30mm. In specific settings, the overlapping width of the two adjacent first baffle bricks 211 can be any value between 22mm, 25mm, 28mm and 20mm-30mm. The inventor has repeatedly found that when the first baffle brick layer 210 built in a cold state rises from room temperature to above 1500°C, the refractory material will expand in all directions, but when the overlapping width of the two adjacent first baffle bricks 211 is set to 20mm-30mm, the first baffle bricks 211 due to high temperature expansion are caused to move away from each other or get close to each other. This range can well ensure that the first baffle bricks 211 are still in an overlapping state.

[0042] In order to better prevent the low eutectic formed on the surface of the refractory material of the large arch 100 and the impurities generated at the expansion joint from flowing into the molten glass along the rear gable 200, a preferred implementation manner is that the number of the first baffle brick layers 210 is two, and the two first baffle brick layers 210 are arranged opposite to each other in the vertical direction, and the height of the upper first baffle brick layer 210 protruding from the rear gable 200 is less than the height of the lower first baffle brick layer 210 protruding from the rear gable 200. Through the above-mentioned arrangement, when the low eutectic formed on the surface of the refractory material of the large arch 100 and the impurities generated at the expansion joint flow along the rear gable 200 to the upper first baffle brick layer 210, the height of the lower first baffle brick layer 210 protruding from the rear gable 200 is greater than the height of the upper first baffle brick layer 210 protruding from the rear gable 200, so that the lower first baffle brick layer 210 can receive the part of the upper first baffle brick layer 210 that overflows from the upper first baffle brick layer 210 due to carrying too much low eutectic and impurities, thereby preventing the low eutectic and impurities from overflowing from the upper first baffle brick layer 210 and then dripping into the glass liquid when excessive accumulation on the upper first baffle brick layer 210 occurs, thereby more effectively solving the problem of eutectic and impurities flowing to the glass liquid along the rear gable 200 and improving the yield of glass products.

[0043] In order to better prevent the low eutectic formed on the surface of the large arch 100 refractory material and the impurities generated at the expansion joint from overflowing from the upper first baffle brick layer 210, specifically, the height range of the upper first baffle brick layer 210 protruding from the rear gable 200 is 60mm-120mm, and the height range of the lower first baffle brick layer 210 protruding from the rear gable 200 is 100mm-150mm. In the specific setting, the height of the upper first baffle brick layer 210 protruding from the rear gable 200 can be 65mm, 70mm, 80mm, 90mm, 95mm, 100mm, 110mm, 115mm and any value between 60mm-120mm, and the height of the lower first baffle brick layer 210 protruding from the rear gable 200 can be 100mm, 110mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm and any value between 100mm-150mm. After repeated research, the inventors found that when the height range of the upper first baffle brick layer 210 protruding from the rear gable 200 is set to 60-120mm, it can be ensured that most of the low eutectic and impurities are gathered in the upper first baffle brick layer 210 and will not overflow downwards, and when the height range of the lower first baffle brick layer 210 protruding from the rear gable 200 is set to 100mm-150mm, on the one hand, it can be ensured that the eutectic and impurities overflowing from the upper first baffle brick layer 210 are gathered on the lower first baffle brick layer 210 and will no longer drip into the glass liquid; on the other hand, it can also prevent the first baffle brick 211 in the lower first baffle brick layer 210 from breaking and falling into the glass liquid when it protrudes too much from the rear gable 200.

[0044] In order to more conveniently allow the lower first baffle brick layer 210 to receive the eutectic and impurities overflowing from the upper first baffle brick layer 210, specifically, the vertical spacing range between the upper first baffle brick layer 210 and the lower first baffle brick layer 210 is 600mm-1500mm. In specific settings, the vertical spacing between the upper first baffle brick layer 210 and the lower first baffle brick layer 210 can be 700mm, 800mm, 900mm, 1050mm, 1150mm, 1300mm, 1450mm and any value between 600mm-1500mm.

[0045] In order to cool the molten glass, a preferred embodiment further comprises a cooling part and a connecting part, wherein the connecting part comprises a small arch, a narrow channel and at least one partition wall, wherein:

[0046] The cooling part is spaced apart from the glass melting part and is located on the side of the rear gable 200 away from the feeding port, and the cooling part covers at least a part of the connecting part;

[0047] An arched hole 220 is opened on the rear gable 200, and a small arch is arranged at the edge of the rear gable 200 close to the arched hole 220. When specifically arranged, the small arch is built from the edge of the arched hole 220 away from the hanging wall to the connected cooling part;

[0048] One end of the narrow channel is connected to the molten pool, and the other end of the narrow channel is connected to the cooling part through the arch hole 220. In the specific setting, the outer side of the glass liquid circulation area surrounded by the molten pool and the narrow channel is provided with pool wall bricks, and the pool wall bricks on the surrounding sides are higher than the glass liquid surface. When the low eutectic formed on the surface of the large arch 100 refractory material and the impurities generated at the expansion joints slowly flow down along the surrounding walls, since the glass liquid circulation area facing the hanging wall and the left and right breast walls has the corresponding molten pool wall, the low eutectic and impurities will flow along the hanging wall and the breast wall to the surrounding of the molten pool wall and will not flow into the glass liquid. However, the part of the narrow channel passing through the arch hole 220 has no setting to block the low eutectic and impurities in the width direction. At this time, the first flow-blocking brick layer 210 is set on the side of the rear gable 200 close to the feeding port, which effectively prevents the low eutectic formed on the surface of the large arch 100 refractory material and the impurities generated at the expansion joints from flowing into the glass liquid in the narrow channel along the rear gable 200, thereby improving the yield rate of glass products.

[0049] At least one partition wall is arranged in the small arch along the arrangement direction of the hanging wall and the rear gable 200. In specific arrangement, the number of the partition walls can be 2, 3, 4 or more;

[0050] At least one second baffle brick layer protruding along the circumference of the partition wall is provided on one side of the partition wall close to the glass melting part. In specific configuration, the second baffle brick layer may have two, three, four or more layers.

[0051] In the process of conveying the molten glass to the cooling part of the above-mentioned glass melting furnace 10, the partition wall prevents the gas in the melting part and the gas in the cooling part from flowing, but one side of the partition wall is affected by the gas in the melting part, and the other side of the partition wall is affected by the gas in the cooling part. Condensate is easily formed on the side of the partition wall affected by the gas in the melting part. In the present invention, at least one second baffle brick layer protruding along the circumference of the partition wall is provided on the side of the partition wall close to the glass melting part, so that the condensate is gathered in the second baffle brick layer, and the condensate is prevented from flowing along the partition wall into the molten glass, resulting in defects such as stones and nodules in the manufactured glass, thereby improving the yield of the glass products. In addition, the design and construction of the second baffle brick layer provided on the partition wall is simple and low in cost, and can effectively solve the problem of condensate flowing along the partition wall into the molten glass.

[0052] In order to make better use of the second baffle brick layer, specifically, the orthographic projection of the second baffle brick layer on the partition wall is a "human" shape, and the tip of the second baffle brick layer faces the small arch. Through the above arrangement, after the condensate flows along the partition wall to the second baffle brick layer, the condensate slowly flows down from the tip of the second baffle brick layer to both sides of the tip, and the condensate flows along both sides of the tip to the joint between the small arch and the partition wall, and then flows along the joint to the ground, which more effectively solves the problem of condensate flowing along the partition wall to the glass liquid, and improves the yield rate of glass products.

[0053] In order to make the second baffle brick layer better able to carry condensate, specifically, the second baffle brick layer includes a plurality of second baffle bricks, and two adjacent second baffle bricks are arranged in an overlapping manner. In the specific arrangement, the overlapping width range of two adjacent second baffle bricks is 20mm-30mm, which can well ensure that when the second baffle bricks expand due to high temperature, whether they move away from each other or get close to each other, the second baffle bricks are still in an overlapping state; the number of second baffle brick layers can also be set to two layers, and the two second baffle brick layers are arranged opposite each other in the vertical direction, and the height of the upper second baffle brick layer protruding from the rear gable 200 is less than the height of the lower second baffle brick layer protruding from the rear gable 200, and the lower second baffle brick layer can bear the part of the upper second baffle brick layer that overflows from the upper second baffle brick layer due to carrying too much condensate; in order to better prevent the condensate from overflowing from the upper second baffle brick layer, the height range of the upper second baffle brick layer protruding from the rear gable 200 is set to 60mm-120mm, The height range of the lower second baffle brick layer protruding from the rear gable 200 is set to 100mm-150mm. On the one hand, it can ensure that most of the condensate is in the upper second baffle brick layer, and on the other hand, the lower second baffle brick layer can ensure that the condensate overflowing from the upper second baffle brick layer is gathered on the lower second baffle brick layer, and it can also prevent the second baffle bricks in the lower second baffle brick layer from breaking and falling into the glass liquid when the second baffle bricks in the lower second baffle brick layer protrude too much from the partition wall; in order to more conveniently allow the lower second baffle brick layer to receive the condensate overflowing from the upper second baffle brick layer, the vertical spacing range of the upper second baffle brick layer and the lower second baffle brick layer can be set to 600mm-1500mm; in addition to the low-cost silica bricks, the second baffle bricks can also use corundum bricks, white jade bricks, zircon bricks, etc. with good corrosion resistance.

[0054] The idea of ​​designing a baffle brick layer on the rear gable 200 and the partition wall of the present invention can be applied to melting furnace structures with gables and partition walls designed for float glass, ultra-thin electronics, high-aluminum glass, photovoltaic glass, and one kiln with multiple lines.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
