[0001] The utility model relates to the technical field of material supply channels, and more specifically to the technical field of a high-efficiency homogenizing material supply channel with the function of self-adjusting the flow of glass liquid. Background Art
[0002] In the glass manufacturing process, the forehearth plays a key role in homogenizing and cooling the glass liquid from melting to the molding machine. The size and structural design of the forehearth are the core of the forehearth.
[0003] The existing inner width of the feed channel is 660mm, and the inner width of the feed channel is reduced to 560mm from the front end of the material basin; the inner height of the feed channel is 180mm, and the inner height of the feed channel is sunken to 278mm from the front end of the material basin. The inner curvature chamfer R150 of the groove brick remains unchanged. This structure does not cause the glass liquid to flip horizontally or up and down, and the height and inner curvature chamfer are uniform. The glass liquid flow is single and the homogenization performance is poor. The structure does not have the ability to adjust the homogenization performance and energy-saving performance. During use, the homogenization and energy-saving effects are poor. Utility Model Content
[0004] The purpose of the utility model is to solve the above technical problems and provide a highly efficient homogenizing feed channel with self-adjusting glass liquid flow. By optimizing the design of the feed structure, the flow direction of the glass liquid is changed, the homogenizing performance is better, and the energy saving is improved.
[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0006] The utility model provides a high-efficiency homogenizing material supply channel with self-adjusting glass liquid flow, comprising a head material channel brick assembly, a middle material channel brick assembly, and a tail material channel brick assembly which are arranged in sequence according to the flow direction of the glass liquid, the material channel width of the head material channel brick assembly is smaller than the material channel width of the middle material channel brick assembly, the material channel width of the middle material channel brick assembly is larger than the material channel width of the tail material channel brick assembly, an expansion groove brick with a gradually increasing material channel width is connected between the head material channel brick assembly and the middle material channel brick assembly, and a contraction groove brick with a gradually decreasing material channel width is connected between the middle material channel brick assembly and the tail material channel brick assembly.
[0007] Specifically, the structure of the feed channel affects the flow of the glass liquid. The old feed channel has a single structure, and the horizontal and vertical liquid flows remain unchanged, making it difficult to achieve the glass liquid homogenization effect. Special consideration is given to achieving the homogenization effect by changing the horizontal and vertical structures. This solution sets an expansion trough brick at the entrance of the feed channel and a contraction trough brick in the middle of the feed channel, which can expand the lateral liquid flow of the glass liquid and make the mixing more uniform. The chamfers of the feed channel trough bricks are changed in many places, and the chamfers are slow, which reduces the static layer of glass liquid entering the forming flow and causing streak defects.
[0008] In one embodiment, an end slot brick with a zoom function is provided at the end of the tail channel brick assembly.
[0009] Specifically, an end slot brick with a zoom function is arranged at the tail, which can expand the lateral flow of the glass liquid flow and make the mixing more uniform.
[0010] In one embodiment, the first material channel brick assembly includes at least one No. 3 groove brick, and arc chamfers are arranged on both sides of the bottom of each No. 3 groove brick.
[0011] In one embodiment, the intermediate material channel brick assembly includes multiple No. 7 groove bricks of the same depth, at least one sunken No. 9 groove brick, and at least one rising No. 8 groove brick, the depth of the No. 7 groove brick is greater than the depth of the No. 8 groove brick and less than the depth of the No. 9 groove brick.
[0012] In one embodiment, a No. 10 trough brick is added on the upper side of the sunken trough brick and the rising trough brick.
[0013] In one embodiment, the inlet height of the end slot brick is higher than the outlet height of the shrinkage slot brick.
[0014] Specifically, at least one sinking trough brick and at least one rising trough brick are arranged in the middle of the feed channel, and the entrance height of the terminal trough brick at the tail is increased to change the height of the glass liquid.
[0015] In one embodiment, the tail channel brick assembly includes at least two No. 2 channel bricks.
[0016] In one embodiment, the shrinkage groove bricks include groove brick No. 6, groove brick No. 4, groove brick No. 5 and groove brick No. 4, which are arranged in sequence according to the flow direction of the molten glass.
[0017] In one embodiment, the size of the No. 10 groove brick is 880*400*150 mm.
[0018] In one embodiment, a No. 11 expansion joint compression brick is provided between the shrinkage groove brick and the middle material channel brick assembly to prevent material leakage.
[0019] The beneficial effects of the utility model are as follows:
[0020] 1. The newly designed channel structure dimensions solve the following problems: changes in the horizontal and vertical glass flow, deep glass in the cooling section, thin glass layer in the homogenizing section, and fewer flame intervals, thereby increasing the mixed convection of the glass liquid and achieving a significant homogenizing effect; at the same time, it also increases the heat demand of the glass liquid, achieving energy saving; at the same time, due to the change in chamfer and the sinking and rising in the middle, the cooling is achieved, the glass flow increases and decreases, and the change range of the fixed layer is small, achieving the purpose of improving the quality of the glass liquid and easy control of the molding temperature. The implementation of this project is of great significance to improving the quality of the glass liquid and the qualified rate of products.
[0021] 2. The self-adjusting flow and flipping action helps to mix the glass liquid in the feed channel, increases the contact opportunities of glass liquid in different areas, avoids local overheating or cooling caused by glass liquid staying in certain areas of the feed channel for too long, maintains the uniformity of glass liquid temperature, and thus improves the homogenization efficiency. The uniformity of ring cutting has been improved from the original C- to B+. After 3 months of operation, no crystallization or streak defects have occurred.
[0022] 3. Improve production flexibility: It can automatically adjust the flow state of glass liquid according to production needs, so that the forehearth can adapt to different production conditions and product specifications. This forehearth design can adapt to different glass formulas and production processes, and has good versatility and adaptability.
[0023] 4. Glass liquid with good homogenization effect helps to improve material utilization, reduce scrap rate and reduce production cost. Enhance production stability: Self-adjusting flow reduces fluctuations in the production process and improves the stability and predictability of the entire production process. And the product yield rate is increased from the original 92% to 94%. Calculated at 3,000 yuan / ton per ton of product and 105 tons per day, the annual increase in qualified rate income is about 2.268 million yuan.
[0024] 5. By replacing the newly designed feeding structure: the self-adjusting flow reduces the dependence on external adjustment means, so that the production process can automatically adjust the liquid flow function through the material channel, and the optimized flow state reduces the demand for additional energy, for example, by reducing the demand for heating or cooling, thus achieving energy saving and consumption reduction. The natural gas consumption of a single material channel is reduced from 16m3 / ton to 10.5m3 / ton. Energy saving of about 34% is achieved. Natural gas is priced at 3.2 yuan / m 3 Calculation shows that the cost saving is RMB 17.6 / ton and the monthly saving is RMB 665,000 per year.
[0025] 6. Preliminary estimates show that the comprehensive value generated is: an additional revenue of approximately RMB 2.9 million per year. In summary, this patented technology of efficient homogenizing feeder with self-adjusting glass liquid flow has brought significant benefits to glass product production through its innovative structural design, especially in improving product quality, optimizing production processes and reducing production costs.

[0064] A No. 11 expansion joint compression brick 4 is arranged between the shrinkage groove brick 5 and the middle material channel brick assembly 3 to prevent material leakage.
[0065] Example 5
[0066] like Figures 5 to 13 As shown, this embodiment provides all the trough brick structures starting from the forehearth entrance, and the process and structural dimensions are as follows:
[0067] S1. From the head channel brick assembly 1, it includes a No. 3 groove brick with the following structure: the inner width of the No. 3 groove brick is 460mm, with an arc R100 chamfer on both sides, an inner height of 180mm, a length of 500mm, the side thickness of the No. 3 groove brick is 140mm, and the bottom thickness of the brick is 150mm.
[0068] S2, expand slot brick 2, which is a slot brick No. 6, with the following structure:
[0069] The length of the back is 50mm, and the other dimensions are the same as those of the No. 3 groove brick (inner width 460mm, with arc R100 chamfers on both sides, inner height 180mm, length 500mm, the side thickness of the No. 3 groove brick is 140mm, and the bottom thickness of the brick is 150mm);
[0070] The length of the front is 50mm, the inner width of the No. 6 groove brick is 600mm, there are R150 chamfers on both sides, the inner height is 180mm, the length is 500mm, the thickness of the two sides of the brick is 140mm, and the bottom thickness of the brick is 150mm.
[0071] The middle length is 400mm, the inner width of the No. 6 groove brick transitions from 460 to 600mm, and there are arcs on both sides that transition from R100 to R150 chamfers. The inner height is 180mm, the thickness of the bricks on both sides is 140mm, and the bottom thickness of the brick is 150mm.
[0072] Note: The transition from No. 3 groove brick to No. 6 groove brick is from the middle part of No. 6 groove brick. The changes are:
[0073] The inner width of the No. 6 groove brick transitions from 460 to 600mm, and the two sides have a transition from R100 to R150 chamfer. This structure expands the glass horizontally and increases the vertical depth, so that the glass liquid can be mixed horizontally and vertically at the same time, which is very good for cooling and homogenization.
[0074] S3, the structure of the intermediate channel brick assembly 3 is as follows:
[0075] S31, passing through four No. 7 slot bricks: No. 7 slot brick length 500mm, same as No. 6 slot brick 50mm length, 4 pieces. This section belongs to the cold section, which is obviously homogenized. The glass liquid in this section has a large amount and a slow flow rate, which plays a good role in the internal homogenization process.
[0076] S32, to the ninth slot brick:
[0077] The rear length is 145mm, the inner width of the No. 9 groove brick is 600mm, there are R150 chamfers on both sides, the inner height is 180mm, the thickness of the two sides of the brick is 140mm, and the bottom thickness of the brick is 150mm.
[0078] The front length is 200 mm, the inner width of the ninth groove brick is 598 mm, there are arcs R150 chamfers on both sides, the inner height is 130 mm, there is a 100 mm empty space on the upper side, the thicknesses of both sides of the brick are 141 mm respectively, the thickness of the lower bottom of the brick is 100 mm, and there is a 100 mm empty space in the upper 100 mm height.

[0080] Note: This section belongs to the second cold section. The sinking in this section continues during the temperature drop. The inner height of the brick is 180 mm and it sinks by 50 mm, and the rest remains basically unchanged. It belongs to the sinking process.
[0081] S33. To the eighth groove brick, it is the reverse of the ninth groove brick.
[0082] The back is 50 mm. The inner width of the eighth groove brick is 600 mm, there are arcs R150 chamfers on both sides, the inner height of the brick is 130 mm, there is a 100 mm empty space on the upper side, the thicknesses of both sides of the brick are 140 mm respectively, and the thickness of the lower bottom of the brick is 100 mm.
[0083] The front is 295 mm. The inner width of the eighth groove brick is 600 mm, there are arcs R150 chamfers on both sides, the inner height of the brick is 180 mm, the thicknesses of both sides of the brick are 140 mm respectively, and the thickness of the lower bottom of the brick is 150 mm.
[0084] The middle length is 150 mm. The inner width of the eighth groove brick symmetrically transitions from 600 mm to 600 mm (330 mm at the center on the left side and 270 mm on the right side), there are arcs R150 chamfers on both sides, the inner height of the brick rises from 130 mm with a 100 mm empty space on the upper side to 180 mm, the thicknesses of both sides of the brick are 140 mm respectively, and the thickness of the lower bottom of the brick transitions from 100 mm to 150 mm.
[0085] Note: The change of this brick is that it rises in the middle section of the eighth groove brick after coming out of the ninth groove brick. Mainly, the original brick thickness of 100 mm becomes 150 mm, the inner height sinks by 50 mm from 130 mm and becomes the normal 180 mm, sinking by 50 mm, and the rest remains basically unchanged. It belongs to the sinking process.
[0086] The total length of the eighth groove brick is 495 mm, with a 5 mm expansion joint left.
[0087] From the ninth groove brick to the eighth groove brick is the method of sinking the liquid flow hole. And a space separating brick, the material channel gate brick of the tenth groove brick with dimensions 8880*400*150 mm, is added above the ninth groove brick and the eighth groove brick. Here, the material channel gate brick has the function of separating the flame space and reducing the heat diffusion between regions.
[0088] After the No. 8 groove brick, put a No. 7 groove brick for transition and equalization.
[0089] S4, then go to the shrinkage groove brick 5, which is the No. 6 groove brick used in reverse.
[0090] Change the liquid flow from 600mm width to 460mm width, and the chamfer from 150mm to 100mm. Control the flow rate of the glass liquid. Leave a 10mm expansion joint in the middle from the No. 7 groove brick to the No. 6 groove brick, and use No. 11 expansion joint compression bricks 330*115*65 on both sides and the bottom to prevent leakage.
[0091] Then move to No. 4 groove brick, No. 5 groove brick, and No. 4 groove brick.
[0092] S5, tail channel brick assembly 6, including two No. 2 slot bricks with unchanged flow rate, unchanged chamfer 100mm, unchanged inner width 460mm and brick thickness 150, and unchanged height 180mm.
[0093] Note: The size conversion brick of No. 6 groove brick is used upside down, the liquid flows horizontally, shrinks, increases the fluidity of the glass, and the longitudinal chamfer R changes from 150mm to 100mm, which increases the height of the glass liquid and makes the glass liquid shallower. This brick belongs to the second cold stage, which increases the flow rate of the glass liquid and reduces the cooling rate. The glass liquid is shallow, such as natural gas heating, and the heat permeability is better.
[0094] The process from No. 6 slot brick to No. 2 slot brick in step S4 and step S5 belongs to the second homogenization and cooling stage.
[0095] S6, to the end slot brick 7, is a No. 1 slot brick and a material basin, the No. 1 slot brick is the size conversion brick of the No. 6 slot brick, the specific structure is as follows:
[0096] The length of the back is 50mm, the width of the No. 1 groove brick changes from 460mm of the No. 6 groove brick to 360mm, the chamfer changes from 100mm to 50mm, the height changes from 180mm to 130mm, the space height is reduced, the brick thickness changes from 150mm to 200mm, and the glass liquid is homogenized again. The steps here further block the generation of stripes. Due to the change in the depth of the glass liquid, the homogenization temperature of the glass liquid increases. The length of the front is 450mm, and the inner cavity width of the No. 1 groove brick gradually transitions from 360mm to 560mm, the chamfer remains unchanged at 50mm, and the brick thickness remains unchanged at 200mm. The side bricks of the No. 1 groove brick are thick and 500mm long. They are trapezoidal cut corner structures for easy installation of the basin. The lower bottom is 300mm, the upper bottom is 200mm, and 20mm*40mm*330 is cut off.
[0097] The rear length of the No. 1 slot brick is 50mm, and the width is changed from 460mm of the No. 6 slot brick to 360mm. The lateral liquid flow is contracted and the flow rate is faster. The chamfer of the No. 1 slot brick is changed from R100mm to R50mm, and the height is changed from 180mm to 130mm. The space height is reduced, and the liquid flow is changed vertically, so that the glass liquid flows faster and the glass liquid is shallower. Compared with the old material channel structure, it is easier to transfer heat to the glass liquid when the homogenization section is heated. The thickness of the No. 1 slot brick is changed from 150mm to 200mm, and the glass liquid is homogenized again. The steps here further prevent the generation of stripes. Due to the change in the depth of the glass liquid, the homogenization temperature of the glass liquid increases.
[0098] In order to solve the problem, after the cold repair of the kiln, a high-efficiency homogenizing feeder with self-adjusting glass liquid flow was redesigned to make the feeder achieve better homogenizing performance, energy saving, and improve the glass qualification rate and product qualification rate.
