[0017] Reference Figure 1-2 The utility model proposes a TFT glass kiln smoke exhaust device, including a horizontal pipe 1 and a vertical pipe 2, wherein one end of the horizontal pipe 1 has a first inlet, and the other end of the horizontal pipe 1 has a first outlet connected to the middle of the vertical pipe 2, a second outlet at the top of the vertical pipe 2 is connected to the inlet of the first smoke exhaust pipeline 3, and a third outlet at the bottom of the vertical pipe 2 is connected to the inlet of the second smoke exhaust pipeline 4. A plug 5 is also adapted to slide in the vertical pipe 2, and the thickness of the plug 5 close to the first outlet is less than the diameter of the first outlet. A driving mechanism 6 is installed to drive the connected plug 5 to drive the plug 5 to slide between the second outlet and the third outlet.
[0018] The use process of the TFT glass furnace smoke exhaust device proposed in the utility model is as follows: in normal use, the plug 5 blocks the third outlet, and the first smoke exhaust pipe 3 is connected. Figure 4The fan in the first smoke exhaust pipeline 3 drives the smoke to enter through the first inlet of the horizontal pipe 1, and then is discharged through the first outlet of the horizontal pipe 1, the vertical pipe 2, the second outlet of the vertical pipe 2, and the first smoke exhaust pipeline 3. When the first smoke exhaust pipeline 3 is blocked or the fan fails, the driving mechanism 6 drives the plug to move to the top of the horizontal pipe 1, so that the second outlet is blocked and the third outlet is opened, and the fan in the second smoke exhaust pipeline 4 is started to drive the smoke to enter through the first inlet of the horizontal pipe 1, and then is discharged through the first outlet of the horizontal pipe 1, the vertical pipe 2, the third outlet of the vertical pipe 2, and the second smoke exhaust pipeline 4. For details, refer to Figure 3 .
[0019] It should be further explained that when the first smoke exhaust duct 3 and the second smoke exhaust duct 4 are switched on, the fan in the first smoke exhaust duct 3 is turned off, and the rotation speed of the fan blades of the fan gradually decreases until it stops completely, thereby causing the flow rate of the smoke through the first smoke exhaust duct 3 to gradually decrease, and the fan in the second smoke exhaust duct 3 is started, and the rotation speed of the fan blades of the fan gradually increases from zero until it reaches a specific speed, thereby causing the flow rate of the smoke through the second smoke exhaust duct 4 to gradually increase, and when the driving mechanism 6 drives the second outlet of the plug 5 to move toward the third outlet, the first channel connecting the first smoke exhaust duct 3 and the cross pipe 1 gradually narrows, so that the flow rate of the smoke entering the first smoke exhaust duct 3 can decrease when the fan speed decreases, and the second channel connecting the second smoke exhaust duct 3 and the cross pipe 1 gradually widens, so that the flow rate of the smoke entering the second smoke exhaust duct 4 can increase when the fan speed increases, so that the pressure in the furnace can be kept stable.
[0020] In the above embodiment, in order to guide the smoke entering the first smoke exhaust pipe 3, the top wall of the plug 5 has a first inclined surface, and the first inclined surface is inclined upward in the direction away from the first outlet toward the second outlet.
[0021] Similarly, in order to guide the smoke entering the second smoke exhaust pipe 4, the bottom wall of the plug 5 has a second inclined surface, and the second inclined surface is inclined downward in the direction away from the first outlet toward the third outlet.
[0022] It should be further explained that a slide groove 21 is provided on the vertical pipe 2 along its length direction, and a protrusion 51 that is adapted to slide with the slide groove 21 and extends to the outside of the vertical pipe 2 is provided on the outer wall of the plug 5 away from the first outlet, and the driving mechanism 6 is fixed on the outer wall of the vertical pipe 2 and is drivingly connected to the protrusion 51.
[0023] To prevent smoke from escaping through the chute 21 , the thickness between the two ends of the first slope and the second slope away from the first outlet is more than twice the length of the chute 21 , so that the plug 5 can block the chute 21 .
[0024] In addition to the above-mentioned blocking method, blocking parts for blocking the slide groove 21 may be fixed on both the first inclined surface and the second inclined surface, and the slide groove 21 may be blocked by the blocking part and the plug 5 .
[0025] The smoke exhaust device proposed in the utility model has the outlets of the first smoke exhaust pipe 3 and the second smoke exhaust pipe 4 connected to the inlet of the smoke exhaust main pipe, a first solenoid valve is installed in the first smoke exhaust pipe 3 and behind the outlet of the first fan, and a second solenoid valve is installed in the second smoke exhaust pipe 4 and behind the outlet of the second fan. The utility model also includes a control unit, which is controlled and connected with the driving mechanism 6, the first solenoid valve and the second solenoid valve. The control unit is also communicatively connected with a pressure detection unit for detecting the pressure in the glass kiln.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
