When the flow gate is adjusted, the above-mentioned particulate matter will fall onto the glass liquid in the glass flow channel, affecting the quality of subsequent glass products, such as CN202224405U. Utility Model Content

[0005] A technical problem to be solved by the present application is that, during the process of adjusting the flow channel gate, particles attached between the flow channel gate and the glass flow channel may fall onto the glass liquid inside the glass flow channel, thus affecting product quality.

[0012] In some embodiments, the cross-sectional area of ​​the air intake duct increases continuously in a direction from the first end of the air intake duct to the second end of the air intake duct.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] like Figure 1 and Figure 2 As shown, the float glass flow channel disclosed in the first embodiment of the present application includes a glass flow channel component 10, a flow control component 20 and a cleaning component 30. The glass flow channel component 10 has an opening 11. The flow control component 20 is movably arranged in the opening 11. The cleaning component 30 includes a cleaning structure 31, an air suction pipeline structure 32 and a negative pressure structure 33. The cleaning structure 31 is connected to the air suction pipeline structure 32, the negative pressure structure 33 is connected to the air suction pipeline structure 32, and the cleaning structure 31 is partially arranged between the flow control component 20 and the opening 11.

[0031] By applying the technical solution of the first embodiment, the smoke generated by the glass liquid in a high temperature environment first contacts the cleaning structure 31 when flowing out from the opening 11, because a cleaning structure 31 is provided between the flow control assembly 20 and the opening 11. Under the action of the negative pressure structure 33, the smoke is sucked into the cleaning structure 31, so it will not contact with the external cold air to generate particles attached to the flow control assembly 20, thereby preventing the particles from falling into the glass flow channel assembly 10. The technical solution of the first embodiment effectively solves the problem in the prior art that in the process of adjusting the flow channel gate, the particles attached between the flow channel gate and the glass flow channel will fall on the glass liquid inside the glass flow channel, affecting the product quality.

[0032] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the cleaning structure 31 includes a first collecting box 311 and a plurality of suction pipes 312. The first collecting box 311 is arranged on both sides of the flow control assembly 20, and the first collecting box 311 is connected to the glass flow channel assembly 10. The first ends of the plurality of suction pipes 312 are connected to the first collecting box 311, and the second ends of the plurality of suction pipes 312 are arranged between the flow control assembly 20 and the opening 11. The high-temperature flue gas is sucked into the first collecting box 311 under the action of the negative pressure structure 33, which prevents the high-temperature flue gas from flowing out from the gap between the flow control assembly 20 and the opening 11, causing the high-temperature flue gas to condense into particles attached to the flow control assembly 20. The plurality of suction pipes 312 are evenly distributed along the gap between the flow control assembly 20 and the glass flow channel assembly 10, ensuring that the high-temperature flue gas will not overflow from the gap. The connection between the intake pipe 312 and the first collecting box 311 is arranged away from the bottom surface of the first collecting box 311, and part of the particulate matter condensed from the smoke is deposited in the first collecting box 311, thereby preventing a large amount of particulate matter from accumulating on the side wall of the intake pipe 312, reducing the cleaning pressure on the staff, reducing the cleaning time, and improving work efficiency.

[0033] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the height of the second end of the air intake pipe 312 in the vertical direction is less than or equal to the height of the opening 11 in the vertical direction. The setting position of the air intake pipe 312 is set according to the contact position of the high-temperature flue gas and the cold air. The setting position of the air intake pipe 312 is lower than the contact position of the high-temperature flue gas and the cold air, thereby effectively avoiding the contact of the high-temperature flue gas with the cold air, and then preventing the high-temperature flue gas from condensing into particulate matter. The height difference between the second end of the air intake pipe 312 and the opening 11 is 0cm to 3cm. When the height difference is less than 0cm, the height of the second end of the air intake pipe 312 in the vertical direction is higher than the height of the opening 11 in the vertical direction, and part of the high-temperature flue gas will contact the cold air to produce particulate matter; when the height difference is greater than 3cm, the air intake pipe 312 extends into the opening too long, the total length of the air intake pipe 312 is large, and the cost increases.

[0034] like Figure 2 As shown, in the technical solution of the first embodiment, the cross-sectional shape of the air intake pipe 312 is rectangular. The rectangular air intake pipe 312 can effectively reduce the gap between adjacent air intake pipes 312, and prevent high-temperature smoke from overflowing from between adjacent air intake pipes 312. The gap between adjacent air intake pipes 312 is less than 1 cm. If the gap between adjacent air intake pipes 312 is greater than 1 cm, high-temperature smoke is likely to overflow.

[0035] like Figure 2As shown, in the technical solution of the first embodiment, the side length of the cross section of the air intake pipe 312 is 3 cm to 5 cm. When the cross section of the air intake pipe 312 is small, the high-temperature flue gas condenses on the inner wall of the air intake pipe 312 and easily blocks the air intake pipe 312. When the cross section of the air intake pipe 312 is large, the air intake pressure is small, which is not conducive to the negative pressure suction of the high-temperature flue gas.

[0036] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the air intake pipe 312 is an arc-shaped pipe section. The arc-shaped air intake pipe 312 can effectively prevent the particles attached to the inner wall of the air intake pipe 312 from accumulating at the corners; compared with the vertical pipeline, the arc-shaped air intake pipe 312 effectively prevents the particles in the air intake pipe 312 from falling into the glass flow channel assembly 10.

[0037] like Figure 1 As shown, in the technical solution of the first embodiment, the cleaning assembly 30 further includes an exhaust pipeline structure 34 and a second collection box 35. The exhaust pipeline structure 34 is connected to the negative pressure structure 33, and one end of the exhaust pipeline structure 34 away from the negative pressure structure 33 is connected to the second collection box 35. Under the action of the negative pressure structure 33, the high-temperature flue gas moves along the air intake pipeline structure 32, and the flue gas temperature is reduced to form particulate matter. Under the action of the negative pressure structure 33, the particulate matter moves along the inside of the air intake pipeline structure 32 to the negative pressure structure 33. Under the action of the negative pressure structure 33, the flue gas and particulate matter are discharged from the exhaust pipeline structure 34 and enter the second collection box 35. The second collection box 35 is detachably connected to the exhaust pipeline structure 34, so as to facilitate timely cleaning of the particulate matter in the second collection box 35.

[0038] like Figure 1 As shown, in the technical solution of the first embodiment, the glass runner assembly 10 further includes a glass runner structure 12 and a pressure detection structure 13, and the pressure detection structure 13 is arranged in the glass runner structure 12 and connected to the inner wall of the glass runner structure 12. The pressure detection structure 13 adopts a pressure sensor, and the pressure detection structure 13 is arranged to detect the internal air pressure of the glass runner structure 12, so as to avoid the fluctuation of the glass liquid level due to the large fluctuation of the internal air pressure of the glass runner structure 12, thereby affecting the quality of subsequent products.

[0039] like Figure 1 As shown, in the technical solution of the first embodiment, the float glass flow channel further includes a control component, which is connected to the pressure detection structure 13, and the control component is connected to the negative pressure structure 33. The pressure detection structure 13 transmits the detection result to the control component, and the control component adjusts the power of the negative pressure structure 33 according to the pressure fluctuation, thereby changing the suction pressure of the suction pipe 312 to avoid excessive pressure fluctuation in the glass flow channel structure 12.

[0040] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the cross-sectional area of ​​the intake pipe 312 is continuously increased in the direction from the first end of the intake pipe 312 to the second end of the intake pipe 312. The intake area is increased, and the overflow of high-temperature flue gas caused by the gap between adjacent intake pipes 312 is avoided. The difference between the technical solution of the third embodiment and the technical solution of the second embodiment is that an electric push rod is provided at the bottom of the cleaning structure 31, and the cleaning structure 31 can be moved in the vertical direction, so the intake pipe 312 can be moved in the vertical direction, thereby changing the distance that the intake pipe 312 extends into the opening 11. Glass liquids with different components have different volatilized flue gas components and different flue gas solidification points. The technical solution of the third embodiment can adjust the distance that the intake pipe 312 extends into the opening 11 according to the solidification points of flue gases with different components, and has stronger versatility.

[0041] From the above, it can be known that a float glass flow channel gate cleaning system (cleaning component 30) includes a cleaning device (cleaning structure 31) arranged on the flow channel cover brick, one end of the device extends to the top of the gap between the flow channel gate (flow control component 20) and the cover brick, and the other end is placed on the flow channel (glass flow channel component 10) cover brick; an air pipe (suction pipeline structure 32) and a negative pressure fan (negative pressure structure 33) and a tin ash collection box (second collection box 35) connected to the cleaning device, and a pressure sensor (pressure detection structure 13) is also arranged in the tin tank flow channel (glass flow channel component 10). The ash suction nozzle (suction pipe 312) of the cleaning device penetrates 1-2 cm into the gap or is parallel to the flow channel cover brick (opening 11). The section from the ash suction nozzle to the tin ash channel is arc-shaped and is connected to the tin ash channel through a thread. The ash suction nozzle is 20-30 cm long and less than 5 cm wide. An air pressure detection device (pressure detection structure 13) is provided at the junction of the gate plate (flow control component 20) under the flow channel cover brick. The frequency of the negative pressure fan is adjustable, and the maximum frequency makes the flow channel pressure fluctuation less than 1Pa. The adjustment frequency of the negative pressure fan is linked to the pressure measuring device (pressure detection structure 13), and the frequency of the negative pressure fan can be adjusted by the change of pressure. The pipe (intake pipeline structure 32) connected to the negative pressure fan and the dust cleaning device is detachable. A float glass flow channel gate cleaning system mainly comprises a tin ash suction device (cleaning structure 31) and a negative pressure collection device (negative pressure structure 33); wherein the tin ash suction device is placed flat on a cover plate brick and symmetrically arranged along the gate plate (flow control component 20); a suction pipe (air suction pipe 312) in the tin ash suction device is located inside or on a gap between the gate plate and the cover plate brick, and the suction pipe is spread along the gap; a pressure measuring device can test the air pressure change above the glass liquid; the tin ash suction device and the negative pressure device are connected through a pipeline (air suction pipeline structure 32), and the pipeline is connected to the tin ash suction device through a thread and can be disassembled; the negative pressure device controls the negative pressure through a fan, and the frequency of the negative pressure can be adjusted; a tin ash collecting device (a second collecting box 35) is connected to the negative pressure device and can be disassembled. The negative pressure device is turned on. Under negative pressure, the tin ash device can absorb the tin ash at the gate gap through the tin tube. Under negative pressure, the tin ash enters the pipeline through the tin ash channel and then enters the tin ash collecting device. When the negative pressure of the negative pressure device is large, the pressure measuring device can sense the change of the airflow above the glass liquid in the flow channel. When the pressure fluctuation is greater than 1Pa, the gate cleaning system will automatically adjust the frequency of the negative pressure device to make the air pressure fluctuation less than 1Pa. When the tin channel and the tin ash collecting device collect a lot of tin ash, they can be disassembled and cleaned, which is simple and convenient. This device can prevent the tin ash from peeling off during the up and down adjustment of the gate, thereby affecting the quality of the glass plate, and will not affect the state of the glass liquid attached to the flow channel, and is easy to disassemble.
