Description

Technical Field

[0001] The invention belongs to the field of TFT-LCD glass substrates, and in particular to a flue control assembly device and a working method thereof. Background Art

[0002] In the production and manufacturing of substrate glass, the kiln is a key equipment in the entire process chain, and its stability and efficiency are directly related to the quality and output of glass products. The flue is an important part of the kiln exhaust system, and the rationality of the exhaust system design is very critical to determine the service life of the kiln.

[0003] Due to the coke and dust produced by chemical substances such as boric anhydride and alumina powder in the glass raw materials at high temperatures, and the limitation of the feeding port position, ultra-fine dust will also enter the flue gas during the feeding process and accumulate in the flue, resulting in the exhaust system being often blocked by coke and dust, and the flue gas cannot be discharged normally. The obstruction of flue gas not only affects the gas flow and heat exchange efficiency in the kiln, but also directly leads to the fluctuation of pressure in the furnace, seriously affecting the stability of kiln production and causing the temperature of the kiln glass liquid to fluctuate. The smooth discharge of smoke depends on the flue assembly, which mainly controls the flow rate and temperature of the kiln flue gas. At present, due to the influence of the flue structure, the smoke emission temperature is too high and cannot be accurately discharged according to the process temperature. Although the air supply system has been introduced to control the temperature of the flue, it is affected by the cross-sectional area of ​​the air inlet of the air supply system and the large-tonnage kiln, and it is impossible to effectively supply air and cool down, making it difficult to discharge the smoke, which in turn affects the stability of the subsequent smoke exhaust system.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0035] See also Figure 1 The present invention provides a flue control assembly device, including a flue box body, a flue cleaning unit and a flue cooling unit, wherein the flue cleaning unit and the flue cooling unit are both installed on the flue box body.

[0036] like Figure 2 As shown, the flue box includes a flue inlet, a flue outlet, a flue gate 9 and a flue small door 7. The flue inlet is arranged at the bottom of the flue box and is designed as a square structure. The kiln smoke enters the flue box from the flue box. The flue outlet is arranged at the top of the flue box and is movably connected to the flue box. A flue outlet flange 1 is arranged at the top of the flue outlet. Sealing cotton is used to seal the flue outlet and the flue box to ensure the normal discharge of smoke. The flue gate 9 is fixed to one side of the flue box by a limit block and opened in an emergency. The flue small door 7 is opened on the flue gate 9, which is usually closed and can be opened for flue cleaning when needed. A cleaning outlet 5 is arranged at the bottom of the flue box, and a cleaning port gate 4 is arranged in the cleaning outlet 5, which not only ensures sealing, but also ensures the smooth falling of crystals.

[0037] The flue cleaning unit is provided with a cleaning scraper 11, such as Figure 4 As shown, the top and bottom of the cleaning scraper 11 are both provided with grooves for guiding the flue cleaning unit to move along the inner wall of the flue. The cleaning scraper 11 is installed at one end of a connecting rod 12, and extraction cleaning is performed through the connecting rod 12. The connecting rod 12 is T-shaped, and a handle 13 is provided at the other end of the connecting rod 12. The handle 13 is connected to a manual drive mechanism 6, and the manual drive mechanism 6 is provided on the flue small door 7 and fixed by a butterfly nut, and is used to drive the cleaning scraper 11 to perform cleaning work. The cleaning scraper 11 is manually controlled to clean and scrape off dirt and crystals on the inner wall of the flue, and is placed in the working position after cleaning.

[0038] The flue cooling unit mainly includes a water cooling module and an air supply module. The water cooling module mainly includes a plurality of water cooling blocks arranged at the flue outlet, one side of the plurality of water cooling blocks is connected to the cooling water inlet 8, and the other side is connected to the cooling water outlet 2, and the cooling water inlet 8 and the cooling water outlet 2 are respectively arranged on two opposite sides of the flue box. When the flue gas flows through, the water cooling module will perform initial filtration and thermal deposition, and the cooling water will exchange heat with the high-temperature flue gas to reduce the flue gas temperature and ensure that the temperature of the flue gas is controlled within the usable range, so that the crystals are introduced into the box for aggregation. The cooled water is discharged from the cooling water outlet 2 for recycling.

[0039] like Figure 3 As shown, the air supply module mainly includes an air supply hole 3 arranged on the side of the flue box and a drainage hole arranged in the flue box. The flue air supply fan divides the air supply into two parts through the air inlet pipe. The air supply hole 3 is a strip structure, and a guide plate 10 is arranged inside the air supply hole 3. Figure 5 As shown, it not only ensures the output of effective air supply volume, but also ensures accurate position adjustment during the cooling control process. The drainage holes of the flue box can ensure that small particles of smoke parallel to the direction of the smoke collide with the position of the flue small door 7 during the discharge process, thereby generating gravity dust accumulation, thereby ensuring that the crystals fall smoothly into the flue box. The air supply holes 3 and drainage holes of the air supply module ensure the normal flow rate of the flue gas, so that the boride crystals in the flue gas are deposited in the flue box as required, which is convenient for cleaning.

[0040] The working method of the flue control assembly device of the present invention comprises:

[0041] The flue gas in the kiln continuously enters the flue box through the flue inlet. The water cooling module cools the flue gas through the circulating water in the water cooling block. The air supply module maintains a certain amount of air supply to ensure the normal flow rate and cooling effect of the flue gas. After cooling treatment by the water cooling module and the air supply module, the flue gas is discharged from the flue outlet.

[0042] After working for a period of time, open the flue door 7, use the cleaning scraper 11 in the flue cleaning unit to clean the inner wall of the flue, and after cleaning, close the flue door 7 and check whether the cleaning port gate 4 of the cleaning outlet 5 is well sealed.

[0043] Regularly check the working status of the water cooling module and the air supply module to ensure the accuracy of the cooling effect and the air supply volume, and to ensure the stable operation and safe production of the kiln system.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
