Description

Technical Field

[0001] The utility model belongs to the field of glass processing equipment, and in particular relates to an alkali-resistant and high-temperature-resistant microbubble device for manufacturing flexible ultra-thin glass. Background Art

[0002] Bubbling technology is widely used in the glass kiln processing process. By introducing gas into the bottom layer of liquid glass in the kiln, rising bubbles are formed. The bubbles drive the liquid glass to flow and absorb small bubbles in the liquid glass, thereby improving the glass melting effect and quality.

[0003] The prior art has a technical solution that uses a vortex tube to generate high-temperature gas suitable for bubbling and low-temperature gas suitable for cooling equipment to achieve a high-temperature resistant effect. However, the continuously generated low-temperature gas has the defect of excessively cooling the equipment, resulting in the high-temperature gas entering the glass kiln being too low in temperature, affecting the glass melting efficiency.

[0004] The utility model designs an alkali-resistant and high-temperature-resistant microbubble device for manufacturing flexible ultra-thin glass to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for manufacturing alkali-resistant and high-temperature-resistant microbubbles for flexible ultra-thin glass comprises a vortex tube, a cooling sleeve and a pressure tube, wherein the cooling sleeve is wrapped around the upper end of the vortex tube, the pressure tube is installed at the lower end of the vortex tube, a vent pipe is connected between the cooling sleeve and the pressure tube, an end cover is installed on the top of the cooling sleeve, a nozzle connected to the upper end of the vortex tube is installed on the end cover, an air inlet, a first air outlet and a second air outlet are respectively provided on the vortex tube, a pressure control valve is installed in the second air outlet, and a baffle mechanism for adjusting the opening and closing state according to temperature changes is installed at the connection between the cooling sleeve and the vent pipe.

[0007] As a preferred solution, the cooling sleeve is provided with a cooling cavity surrounding the outside of the vortex tube, and a cavity located between the cooling cavity and the ventilation pipe. The baffle mechanism includes a fixed baffle and a movable baffle arranged in the cavity. The fixed baffle and the movable baffle block the cooling cavity and the ventilation pipe. The fixed baffle and the movable baffle are respectively provided with a first through hole and a second through hole. The first through hole and the second through hole are staggered and not connected. A temperature sensing control component in contact with the movable baffle is installed in the cavity.

[0008] As a preferred solution, the temperature sensing control component includes a bimetallic strip installed on the end cover, the bimetallic strip extends into the cavity, a moving baffle is rotatably connected to the cavity, a lever in contact with the top of the bimetallic strip is installed on the moving baffle, and a counterweight block is installed at the bottom of the moving baffle.

[0009] As a preferred solution, when the bimetallic strip is deformed by heat, the moving baffle will rotate and the first through hole will be connected with the second through hole.

[0010] As a preferred solution, the fixed baffle is arranged close to the ventilation pipe, and a ventilation groove connected to the first through hole is arranged on the side of the fixed baffle close to the ventilation pipe.

[0011] As a preferred solution, the second air outlet is always connected to the cooling chamber.

[0012] As a preferred solution, the upper end of the vortex tube discharges hot air flow, and the lower end discharges cold air flow.

[0013] Compared with the existing technology, the advantages of the utility model are:

[0014] 1. The baffle mechanism designed in the utility model adjusts its opening and closing state as the temperature changes. Therefore, when the equipment is in a safe temperature range, the low-temperature gas generated by the vortex tube will not cool the upper end of the vortex tube and the nozzle, avoiding excessive cooling of the high-temperature gas generated by the vortex tube and introduced into the glass kiln. Therefore, while maintaining the cooling of the equipment to achieve the high-temperature resistance function, it is avoided that the equipment introduces too low temperature gas into the glass kiln to affect the glass processing process.

[0015] 2. The bimetallic strip designed in the utility model has the characteristic that the degree of bending increases with increasing temperature. When the temperature is still rising due to too little low-temperature gas, the area connected between the first through hole and the second through hole will continue to increase, thereby increasing the flow rate of the low-temperature gas.

[0016] 3. The nozzle designed by the utility model is installed on the end cover, which has the advantages of independent setting and easy disassembly and assembly, thereby reducing the cost of replacing the entire equipment due to high temperature and other corrosion phenomena that cause the equipment to be unable to work stably.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] A device for manufacturing alkali-resistant and high-temperature-resistant microbubbles for flexible ultra-thin glass, such as Figure 1 and Figure 2 As shown, it includes a vortex tube 1, a cooling jacket 2 and a pressure tube 3, the cooling jacket 2 is wrapped around the upper end of the vortex tube 1, the pressure tube 3 is installed at the lower end of the vortex tube 1, and a vent pipe 4 is connected between the cooling jacket 2 and the pressure tube 3. The upper end of the vortex tube 1 discharges hot air flow, and the lower end discharges cold air flow;

[0025] An end cover 5 is installed on the top of the cooling sleeve 2, and a nozzle 6 connected with the upper end of the vortex tube 1 is installed on the end cover 5. The vortex tube 1 is installed below the glass kiln through a bracket, and the nozzle 6 extends into the glass kiln. An air inlet 7, a first air outlet 8 and a second air outlet 9 are respectively provided on the vortex tube 1, the cooling sleeve 2 and the pressure tube 3. A pressure control valve is installed in the second air outlet 9. A baffle mechanism 10 for adjusting the opening and closing state according to temperature changes is installed at the connection between the cooling sleeve 2 and the ventilation pipe 4.

[0026] After the high-pressure gas introduced from the air inlet 7 passes through the vortex tube 1, the high-temperature gas is discharged from the port connecting the vortex tube 1 and the nozzle 6, and is introduced into the glass furnace through the nozzle 6 to form floating bubbles in the liquid glass. The port connecting the vortex tube 1 and the pressure pipe 3 discharges low-temperature gas, which is stored in the pressure pipe 3 and the ventilation pipe 4. If the baffle mechanism 10 is triggered due to excessive temperature to connect the cooling sleeve 2 and the ventilation pipe 4, the low-temperature gas is passed into the cooling sleeve 2 for cooling. If excessive low-temperature gas is stored in the pressure pipe 3 and the ventilation pipe 4, causing the pressure to rise, the pressure control valve in the second air outlet 9 opens and discharges excess low-temperature gas.

[0027] like Figures 2 to 4As shown, the cooling sleeve 2 is respectively provided with a cooling cavity 11 surrounding the outside of the vortex tube 1, and a cavity 12 located between the cooling cavity 11 and the vent pipe 4, the baffle mechanism 10 includes a fixed baffle 13 and a moving baffle 14 arranged in the cavity 12, the fixed baffle 13 and the moving baffle 14 block between the cooling cavity 11 and the vent pipe 4, the fixed baffle 13 and the moving baffle 14 are respectively provided with a first through hole 15 and a second through hole 16, the first through hole 15 and the second through hole 16 are staggered and not connected, the second air outlet 9 is always connected to the cooling cavity 11, and a temperature sensing control component in contact with the moving baffle 14 is installed in the cavity 12.

[0028] like Figure 3 As shown, the temperature sensing control component includes a bimetallic strip 17 installed on the end cover 5, the bimetallic strip 17 extends into the cavity 12, the moving baffle 14 is rotatably connected to the cavity 12, a lever 18 in contact with the top of the bimetallic strip 17 is installed on the moving baffle 14, and a counterweight block 19 is installed at the bottom of the moving baffle 14.

[0029] like Figure 5 As shown, the fixed baffle 13 is arranged closely to the ventilation pipe 4 , and a ventilation groove 20 connected to the first through hole 15 is arranged on the side of the fixed baffle 13 close to the ventilation pipe 4 .

[0030] like Figure 2 and Figure 3 As shown, in the initial state, the first through hole 15 and the second through hole 16 are staggered and not connected. When the temperature of the structures such as the vortex tube 1 and the end cover 5 is too high, the bimetallic strip 17 bends due to the different thermal expansion coefficients in the high temperature environment. The top of the bimetallic strip 17 pushes the lever 18 and drives the moving baffle 14 to rotate. The rotation of the moving baffle 14 will cause the first through hole 15 to be connected with the second through hole 16. The low-temperature gas in the pressure pipe 3 and the vent pipe 4 is passed into the cooling chamber 11 to cool the surrounding components. After the ambient temperature drops, the bimetallic strip 17 recovers, and the moving baffle 14 reverses and resets itself due to the counterweight block 19. According to the characteristic that the bimetallic strip 17 bends more as the temperature increases, when the temperature is still rising due to too little low-temperature gas, the area connected between the first through hole 15 and the second through hole 16 will continue to increase, thereby increasing the flow rate of the low-temperature gas.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
