Description

Technical Field

[0001] The utility model belongs to the technical field of TFT liquid crystal glass manufacturing, and in particular relates to an auxiliary device for cleaning coke in a flue of a glass kiln and a glass kiln. Background Art

[0002] At present, in the production and manufacturing of TFT glass, due to the high content of boron in the glass components, the volatilization amount of boron in the glass production is large, which leads to a high content of boron in the flue gas. In actual production operations, the flue discharges the exhaust gas after combustion in the furnace, and the high-temperature flue gas cools down rapidly in the flue. The particulate matter in the exhaust gas condenses to form smoke slag and easily adheres to the inner wall of the smoke pipe. The smoke slag accumulates and condenses on the inner wall of the flue for a long time, which may cause the flue to be blocked. Based on this, it is necessary to clean the flue from time to time to dredge the flue.

[0003] At present, due to the long flue pipe and many turns, it is impossible to confirm the specific location of the blockage. It is necessary to open the flange section by section to check the flue. Each time the flange is opened, it will affect the furnace pressure. If the flange opening operation time is long, it will also have a greater impact on the process. The flue inspection port has a greater impact on the furnace pressure. Frequent opening and inspection is not conducive to daily process control and is prone to frequent defects. Therefore, in summary, in the current production and manufacturing of TFT glass, the flange needs to be opened many times during the cleaning operation of the smoke residue in the flue, which has a greater impact on the furnace pressure and is not conducive to daily process control.

[0037] How to provide a flue auxiliary device which is convenient for observing the coking state in the flue, convenient for cleaning the coke, and has little influence on the furnace pressure during the inspection and cleaning of the coke.

[0038] like Figure 1 As shown, the utility model provides an auxiliary device for decoking the flue of a glass kiln, comprising a device body, which can be installed on the decoking port 6 of the flue 1 to be decoked, so as to inspect the flue 1 to be decoked; the device body comprises an observation port assembly and a plugging assembly arranged thereon; wherein: the observation port assembly comprises a mounting seat 2 and an observation port 8 opened on the mounting seat 2, and the observation port 8 can form a decoking observation channel with the decoking port 6; the plugging assembly can be installed / removed on the mounting seat 2, so as to block / open the observation port 8; the plugging assembly can make the observation port 8 in a blocked or blocked and observed state when installed on the mounting seat 2; at least a part of the plugging assembly is a transparent structure. Based on this, in some embodiments, the utility model mounts the mounting seat 2 on the decoking port 6 for the flue, and then slides and installs the plugging assembly on the mounting seat 2, so as to block the decoking port 6 of the flue or observe it under the blocked state. The utility model is an auxiliary device for cleaning coke in a flue of a glass kiln, and can be installed at multiple bends in the flue, so as to facilitate observation of the coking state in all areas inside the flue, thereby avoiding blind spots and causing flue blockage.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the mounting base 2 is provided with slide rails 7 on the upper and lower sides of the observation port 8, respectively, and the blocking component is a plate-like structure, and the blocking component can be located between the two slide rails 7 and slide along the slide rails 7. The blocking component of the utility model is a plate-like structure, which is slidably installed between the two slide rails 7 along the length direction, and then the observation port 8 is blocked or opened by sliding.

This operation can reduce the fluctuation of the furnace pressure and improve the stability of the entire process. Through experimental tests, it is found that: during the coke clearing work, compared with the prior art, the fluctuation of the furnace pressure in the prior art is ±80Pa, and after adopting the auxiliary device for coke clearing of the flue of a glass kiln furnace of the utility model, the coke clearing operation can achieve a fluctuation of the furnace pressure of ±5Pa. Therefore, by adopting the auxiliary device of the utility model, the influence of the cleaning process on the furnace pressure can be greatly reduced, and the daily process control is optimized.
