Description

Technical Field

[0001] This utility model relates to the technical field of glass melt unloading devices, specifically to a high-temperature glass melt unloading device for a tank furnace. Background Technology

[0002] In the glass manufacturing industry, the tank furnace is a key piece of equipment for melting glass raw materials, and its operating efficiency and stability directly affect the quality of glass products and production costs. For tank furnaces with a daily design capacity of 15 to 20 tons, efficient and environmentally friendly melting technology is the core to improving both capacity and quality. Oxygen-fired technology, as an advanced heating method, significantly improves thermal efficiency through the complete combustion of pure oxygen and fuel, and effectively reduces emissions of harmful gases such as nitrogen oxides, making it an important way to achieve a green glass melting process.

[0003] However, during the long-term operation of a tank furnace, as the furnace age increases (usually 4 years), the refractory materials inside the furnace gradually wear down, and impurities accumulated in the molten glass also affect product quality. At this point, a cold repair of the tank furnace is necessary to restore its working performance. During the cold repair process, safely and efficiently draining the remaining high-temperature molten glass from the furnace becomes an extremely challenging task. Traditional methods often suffer from complex operations, high safety risks, and incomplete drainage, which not only prolongs downtime and increases maintenance costs but may also cause secondary pollution to the environment.

[0004] Therefore, it is particularly important to design a high-temperature molten glass unloading device for tank furnaces that can meet the daily high-efficiency melting requirements while facilitating the safe discharge of molten glass during cold repairs. This device must possess high stability and reliability to ensure that molten glass does not leak during unloading, thus preventing injury to operators or fires and other safety accidents.

[0028] Please see Figures 1-3As shown, this utility model is a high-temperature molten glass unloading device for a bath furnace, including a secondary beam supporting steel structure 1 fixedly installed on the third floor. A high-temperature bath furnace 2 is fixedly installed on the upper end of the secondary beam supporting steel structure 1. A bath furnace throat pipe 3 is provided on the side end of the high-temperature bath furnace 2. A bottom sealing component 4 is fixedly installed on the bottom sealing component 4. An unloading component is provided below the bottom sealing component 4. The unloading component includes an unloading hopper 6 fixedly installed on the third floor. A stainless steel unloading pipe 5 is fixedly connected to the lower outlet of the unloading hopper 6. The outlet of the stainless steel unloading pipe 5 extends to the receiving box on the first floor of the factory building.

[0029] In an optional embodiment, the pool bottom sealing assembly 4 is provided with a heating gun for melting and solidifying the sealing port glass.

[0030] It should be noted that the solidified glass sealing the opening is melted using a heat gun, and the opening is then opened with a steel rod to allow the molten red glass to flow down.

[0031] In an optional embodiment, the discharge hopper 6 is a trumpet-shaped stainless steel discharge pipe.

[0032] It should be noted that the trumpet-shaped discharge pipe ensures complete material collection.

[0033] In an optional embodiment, a bottom baffle 8 is provided at the lower outlet of the stainless steel unloading pipe 5.

[0034] It should be noted that the bottom baffle 8 blocks the stainless steel unloading pipe 5 when the unloading assembly is not in use.

[0035] In an optional embodiment, two sets of symmetrically distributed water pipe supports 11 are fixedly arranged on the outer periphery of the unloading hopper 6. Spray water pipes 9 are fixedly installed on the water pipe supports 11 through water pipe collars 13, and high-pressure water guns 14 are installed at the outlet of the spray water pipes 9.

[0036] It should be noted that the high-pressure water gun 14 rapidly cools the high-temperature molten glass (typically ≥1200℃) using a high-pressure water flow (working pressure 8-15MPa), inducing thermal stress in the glass due to the sudden temperature change, causing it to shatter and break into smaller pieces, thus preventing large glass fragments from accumulating and clogging the pipes. The impact force of the high-pressure water flow directly acts on the molten glass flow, further breaking the glass pieces into smaller particles, improving subsequent recycling efficiency. The continuous high-pressure water flow washes the inner wall of the unloading pipe, reducing the adhesion of high-viscosity molten glass and preventing residue accumulation.

[0037] In an optional embodiment, the high-pressure water gun 14 has a rotary structure and the spray angle is adjustable.

[0038] It should be noted that the rotating sprayer allows for flexible adjustment of the spray angle, ensuring that the unloading hopper 6 is thoroughly sprayed.

[0039] In an optional embodiment, an annular spray pipe 12 is fixedly installed at the inlet edge of the unloading hopper 6. Two sets of cooling water pipes 7 are connected to the annular spray pipe 12, and a number of spray nozzles arranged in an annular array are provided on the inner side of the annular spray pipe 12.

[0040] It should be noted that the annular spray pipe 12 is used for initial cooling of the inlet area of ​​the unloading hopper 6, while the high-pressure water gun 14 extends along the pipe to cover the area, ensuring temperature control and crushing effect throughout the process.

[0041] In an optional embodiment, both the spray pipe 9 and the cooling water pipe 7 are fixedly equipped with a water volume regulating valve 10 for controlling the spray water volume.

[0042] It should be noted that the water pressure can be adjusted from 30 to 250 L / min by the water flow regulating valve 10, which can be adapted to different glass liquid properties and unloading speed requirements, and optimize the cooling and crushing effect.

[0043] In an optional embodiment, the inner walls of the stainless steel unloading pipe 5 and the unloading hopper 6 are coated with a silicon carbide or silicon nitride wear-resistant coating.

[0044] It should be noted that the wear-resistant coating effectively improves the service life of the pipe.

[0045] In an optional embodiment, the stainless steel unloading pipe 5 and the unloading hopper 6 are provided with a double-layer heat insulation structure on their outer layers.

[0046] It should be noted that the double-layer heat insulation structure improves the heat insulation performance of the stainless steel unloading pipe 5 and the unloading hopper 6, preventing burns.

[0047] The working principle of this utility model is as follows: On the cement floor of the third floor at the bottom of the furnace, corresponding to the bottom sealing component 4, a funnel-shaped unloading hopper 6 is welded to the ground. The stainless steel unloading pipe 5 at the bottom of the unloading hopper 6 leads directly to the receiving box on the first floor of the factory. When the furnace 2 needs to be unloaded for cold repair, the bottom sealing component 4 of the unloading port is opened, a special heating gun is placed on it, the solidified glass at the sealing port is melted, and the sealing port is opened with a steel rod so that the red glass liquid flows down.

[0048] At the top of the bell mouth, a ring-shaped spray pipe 12 and a spray water pipe 9 are installed respectively. Each water pipe is equipped with a flow regulating valve 10 to control the water volume. As the red glass liquid flows down from the bell mouth, the high-pressure water gun 14 sprays high-pressure water continuously to cool it. After passing through a long unloading pipe from the third floor to the first floor, when the red glass enters the receiving box at the bottom, the cylindrical red glass is shattered and crushed in time, preventing the unloaded red glass from accumulating at the bottom and causing blockage of the entire stainless steel unloading pipe. The glass material is separated from the water and collected in the receiving box, thus ensuring the safe, orderly and continuous unloading of the furnace until the furnace is empty.

[0049] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
