[0002] Glass bottles are a widely used glass product, mainly used for storing liquid foods or beverages, and are widely used in fields such as food, beverage, chemical industry, and pharmaceutical industry.

As the temperature decreases during forming, the viscosity of the glass liquid gradually increases and hardens, and the unescaped bubbles are finally solidified in the glass. When the glass product is made, it may cause bubbles to remain inside the glass bottle, making the entire glass bottle look very turbid, with poor light transmittance, affecting the aesthetics and quality of the finished glass bottle, and unable to meet the needs of the public.

The shaft drives the stirring blades to rotate through a plurality of connecting parts to stir and homogenize the glass liquid in the reaction container, so that the bubbles in the glass liquid flow in a circular shape during the stirring and homogenization process. When the shaft rotates, it drives the short rod and the long rod to rotate, and guides the bubbles in the glass liquid to gather towards the center of the liquid surface in a circular shape through the bubble guiding inclined rod and the reinforcing inclined rod;

[0022] S3. According to the real-time liquid level of the glass liquid in the reaction container, a plurality of hollow balls at the bottom of the arc-shaped bottom plate move up and down through buoyancy, so that the E-shaped moving block slides in the moving groove, and the rotating rod is driven to rotate by the rotation of the shaft, so that the needles on the deepening rod pierce the bubbles gathered on the liquid surface;

While the shaft is rotating, under the action of the planetary speed increaser, the exhaust fan starts to work to pump air out of the reaction container, so that a negative pressure is generated inside the reaction container, the volume of the bubbles increases and they rise faster, the gas inside the bubbles bursts the bubbles, the bubbles float out of the surface of the glass liquid and then burst and disappear, and the gas enters the sealing cylinder;

[0024] S5. When the exhaust fan rotates, it drives the arc-shaped rotating block to rotate in the sealing cylinder. When the top inclined plane of the arc-shaped rotating block contacts the bottom inclined plane of the arc-shaped baffle, under the action of the dovetail slider and the dovetail chute, the arc-shaped baffle is pushed up by the arc-shaped rotating block, exposing the exhaust hole, so that the gas is discharged out of the air outlet cylinder;

[0026] The beneficial effects of the present invention:

[0027] 1. Heat the glass liquid in the reaction vessel through a heating component to clarify it, and drive the stirring component in the reaction vessel by a driving motor to stir and homogenize the glass liquid, gathering the bubbles in a ring shape towards the center of the liquid surface for elimination, so as to avoid affecting the appearance and quality of the finished glass bottle and meet the needs of the public.

[0028] 2. According to the real-time liquid level of the glass liquid in the reaction vessel, the hollow ball moves up and down through buoyancy, driving the arc-shaped bottom plate to move up and down, causing the E-shaped moving block to slide in the moving groove, and driving the rotating rod to rotate through the rotation of the shaft rod, so that the thorns on the deepening rod pierce the rising and gathering bubbles, further improving the defoaming efficiency.

[0029] 3. Exhaust air from the inside of the reaction vessel through an exhaust fan to create a negative pressure inside the reaction vessel, increasing the volume of the bubbles and accelerating their rise. The gas inside the bubbles bursts the bubbles. When the exhaust fan operates, it drives the arc-shaped rotating block to rotate in the sealing cylinder, causing the arc-shaped rotating block to push the arc-shaped baffle upwards when passing through the arc-shaped baffle, exposing the exhaust hole on one side, so that the extracted air flows from the exhaust hole into the inner cavity of the air outlet cylinder and is discharged outside the air outlet cylinder.

The reaction vessel 1 includes a vessel body, support legs arranged at the bottom of the vessel body, a sealing cover arranged at the top of the vessel body, a feed port arranged at the top of the sealing cover, and a discharge port arranged at one side of the bottom of the vessel body. And the number of the feed ports is not less than two. A driving motor 2 is installed at the bottom of the reaction vessel 1. A heating and stirring unit 3 is installed in the inner cavity of the reaction vessel 1. A buoyancy defoaming unit 4 is installed at the top of the heating and stirring unit 3. The buoyancy defoaming unit 4 can be a defoaming agent, and the defoaming agent will react with the gas in the bubble, converting the original bubble into a liquid, and these liquids can fill the bubbles in the glass liquid, thereby making the bubbles disappear. A gas extraction defoaming unit 5 is arranged at the top of the buoyancy defoaming unit 4. The gas extraction defoaming unit 5 can be a vacuum pump and a one-way valve. The glass liquid is placed in a vacuum environment, and the gas in the liquid bubble is extracted, thereby forming a low-pressure area, and the bubbles will gradually shrink and finally disappear.

[0046] The heating and stirring unit 3 includes a heating component 31 installed in the inner cavity of the reaction vessel 1 and a stirring component 32 installed in the wall body of the reaction vessel 1. The heating and stirring unit 3 is used to heat and stir the glass liquid before forming in the reaction vessel 1, so that the bubbles in the glass liquid float to the liquid surface.

[0047] The heating component 31 includes a heating cavity 311 opened in the wall body of the reaction vessel 1, a heater 312 installed in the heating cavity 311, a liquid passing port 313 opened at the top of the heating cavity 311, and a liquid discharge port 314 opened at the bottom of the heating cavity 311. After the heat exchange liquid is introduced into the heating cavity 311 through the liquid passing port 313, it is heated by the heater 312 to raise the temperature and clarify the glass liquid in the reaction vessel 1. After the defoaming work is completed, the heat exchange liquid is discharged from the liquid discharge port 314.

[0048] The stirring component 32 includes a shaft rod 321 connected to the output end of the driving motor 2 through a coupling, a plurality of connecting parts 322 connected to both sides of the shaft rod 321, and stirring blades 323 connected to the ends of the connecting parts 322 far away from the shaft rod 321. And the stirring blades 323 are arranged at an inclination of 45°, and a plurality of through holes are opened on the surface of the stirring blades 323 to reduce the resistance when stirring the glass liquid. When the shaft rod 321 rotates, the stirring blades 323 are driven to rotate simultaneously under the connection of the connecting parts 322, so as to stir and homogenize the heated glass liquid in the reaction vessel 1, and make the bubbles flow in a circular shape during the stirring and homogenizing process;

[0049] The stirring assembly 32 further includes short rods 324 connected to the front and back of the shaft rod 321, long rods 325 located at the bottom of the short rods 324 and connected to the shaft rod 321, bubble guiding inclined rods 326 connected to the ends of the short rods 324 away from the shaft rod 321, and reinforcing inclined rods 327 connected between the short rods 324 and the long rods 325. When the shaft rod 321 rotates, it drives the short rods 324 and the long rods 325 to rotate. The bubble guiding inclined rods 326 and the reinforcing inclined rods 327 guide the bubbles in the molten glass to gather in a circular shape towards the center of the liquid surface. The reinforcing inclined rods 327 reinforce the connection strength between the short rods 324 and the long rods 325 and improve the guiding force for the flow direction of the bubbles.

[0050] During use, heat exchange liquid is introduced into the heating chamber 311, and the heater 312 is turned on to heat the heat exchange liquid to a specified temperature. The molten glass to be defoamed and formed is added into the reaction vessel 1. The temperature of the molten glass is controlled so that the molten glass is clarified within the viscosity range where bubbles can be homogenized and eliminated. The drive motor 2 is turned on to drive the shaft rod 321 to rotate.

[0051] The shaft rod 321 drives the stirring blades 323 to rotate through a plurality of connecting parts 322 to stir and homogenize the molten glass in the reaction vessel 1, so that the bubbles in the molten glass flow in a circular shape during the stirring and homogenizing process. At this time, the flow direction of the bubbles is as Figure 11 shown. When the shaft rod 321 rotates, it drives the short rods 324 and the long rods 325 to rotate. The bubble guiding inclined rods 326 and the reinforcing inclined rods 327 guide the bubbles in the molten glass to gather in a circular shape towards the center of the liquid surface. At this time, the flow direction of the bubbles is as Figure 12 shown;

[0052] The molten glass in the reaction vessel 1 is heated and clarified by the heating assembly 31, and the drive motor 2 drives the stirring assembly 32 in the reaction vessel 1 to stir and homogenize the molten glass, gathering the bubbles in a circular shape towards the center of the liquid surface for elimination, avoiding affecting the appearance and quality of the finished glass bottle and meeting the needs of the public.

[0053] Example 2, referring to Figure 4 、 Figure 5 and Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the buoyancy defoaming unit 4 includes a buoyancy assembly 41 installed on the shaft rod 321. The buoyancy assembly 41 includes moving grooves 411 opened on the front and back of the shaft rod 321, and the moving grooves 411 are located at the top of the stirring assembly 32. The buoyancy assembly 41 further includes E-shaped moving blocks 412 slidably connected in the moving grooves 411 and connecting plates 413 connected to both sides of the E-shaped moving blocks 412, and threaded holes are opened in the connecting plates 413;

[0054] The buoyancy assembly 41 further includes a fixing bolt 414 threadedly connected to the inside of the connecting plate 413 through a threaded hole, and a fixing nut 415 threadedly connected to the fixing bolt 414. A gasket is installed between the fixing bolt 414 and the fixing nut 415 to reduce pressure and prevent loosening. The buoyancy assembly 41 also includes an arc-shaped bottom plate 416 connected to the bottom of the E-shaped moving block 412, and a plurality of hollow balls 417 connected to the bottom of the arc-shaped bottom plate 416. The hollow balls 417 are made of alumina and are heat-resistant. The alumina shell of the alumina hollow balls 417 has a relatively small density. Therefore, the repulsive force inside the hollow balls 417 in the molten glass is greater than the pressure of the external molten glass on the alumina shell, so that the alumina hollow balls 417 can be suspended in the molten glass. The buoyancy causes the hollow balls 417 to move up and down, driving the arc-shaped bottom plate 416 to move up and down, thereby causing the E-shaped moving block 412 to slide in the moving groove 411.

[0055] The buoyancy defoaming unit 4 further includes a defoaming assembly 42 installed on the buoyancy assembly 41. The defoaming assembly 42 includes a rotating rod 421 connected to the back of the E-shaped moving block 412, a plurality of deepening rods 422 connected to the bottom of the rotating rod 421, and a plurality of thorns 423 installed on the surface of the deepening rods 422. The defoaming assembly 42 is located within the interval of the angle between any stirring blade 323 and any short rod 324. When the E-shaped moving block 412 moves, it drives the rotating rod 421 to move, so that the bottom ends of the deepening rods 422 penetrate into the molten glass. When the shaft rod 321 rotates, the thorns 423 on the surface of the deepening rods 422 pierce the bubbles gathered on the liquid surface.

[0056] During use, according to the real-time liquid level of the molten glass in the reaction vessel 1, a plurality of hollow balls 417 at the bottom of the arc-shaped bottom plate 416 move up and down through buoyancy, driving the arc-shaped bottom plate 416 to move up and down, so that the E-shaped moving block 412 slides in the moving groove 411, thereby driving the rotating rod 421 connected to the E-shaped moving block 412 to move up and down, making the ends of a plurality of deepening rods 422 at the bottom of the rotating rod 421 penetrate into the molten glass. The rotation of the shaft rod 321 drives the rotating rod 421 to rotate, so that the thorns 423 on the deepening rods 422 pierce the bubbles gathered on the liquid surface;

[0057] According to the real-time liquid level of the molten glass, the buoyancy assembly 41 drives the defoaming assembly 42 to move up and down. During the rotation of the shaft rod 321, the defoaming assembly 42 pierces the rising and gathered bubbles, further improving the defoaming efficiency.

[0058] The remaining structure is the same as that of Embodiment 1.

[0059] Embodiment 3, refer to Figure 7 、 Figure 8 、 Figure 9 and Figure 10, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the air extraction and defoaming unit 5 includes a planetary speed increaser 51 installed above the shaft rod 321, and the planetary speed increaser 51 is connected to the inner wall of the reaction vessel 1 through a fixed rod to ensure the normal operation of the planetary speed increaser 51. The top end of the shaft rod 321 is connected to the input end of the planetary speed increaser 51. The air extraction and defoaming unit 5 further includes an exhaust fan 52 connected to the output end of the planetary speed increaser 51 and an air outlet cylinder 53 installed on the top of the reaction vessel 1, and the exhaust fan 52 is located inside the air outlet cylinder 53. The exhaust fan 52 is composed of a rotating shaft and fan blades. The fan blades are sleeved on the shaft wall of the rotating shaft. One end of the rotating shaft is connected to the output end of the planetary speed increaser 51. And a through hole is opened at the top of the air outlet cylinder 53. The reaction vessel 1 is evacuated by the exhaust fan 52, so that a negative pressure is generated inside the reaction vessel 1.

[0060] The air extraction and defoaming unit 5 further includes an exhaust assembly 54 installed inside the air outlet cylinder 53. The air extracted by the exhaust fan 52 is discharged outside the air outlet cylinder 53 through the exhaust assembly 54. The exhaust assembly 54 includes a connecting rod 541 connected to the top of the rotating shaft of the exhaust fan 52, a cross plate 542 connected to the top of the connecting rod 541, and an arc-shaped rotating block 543 connected to the end of the cross plate 542. And the cross-sectional view of the arc-shaped rotating block 543 is a right trapezoidal surface. The exhaust assembly 54 further includes a sealing cylinder 544 installed inside the air outlet cylinder 53. An exhaust channel is formed between the inner wall of the air outlet cylinder 53 and the outer wall of the sealing cylinder 544. The exhaust assembly 54 further includes exhaust holes 545 opened on both sides of the sealing cylinder 544, dovetail chute 546 opened on both sides of the exhaust holes 545, dovetail sliders 547 slidably connected in the dovetail chute 546, and an arc-shaped baffle 548 connected to the inner side of the dovetail slider 547. And the arc-shaped baffle 548 is provided with a bottom inclined plane adapted to the top inclined plane of the arc-shaped rotating block 543. When the exhaust fan 52 rotates, it drives the arc-shaped rotating block 543. When the top inclined plane of the arc-shaped rotating block 543 contacts the bottom inclined plane of the arc-shaped baffle 548, the arc-shaped baffle 548 is pushed up by the arc-shaped rotating block 543, thereby exposing the exhaust holes 545.

[0061] During the use process, while the shaft rod 321 rotates, under the speed increasing effect of the planetary speed increaser 51, the exhaust fan 52 starts to work to evacuate the reaction vessel 1, so that a negative pressure is generated inside the reaction vessel 1. The volume of the bubbles increases and the rising speed towards the liquid surface is accelerated. The gas in the bubbles bursts the bubbles. After the bubbles float out of the surface of the glass liquid, they burst and disappear, and the gas enters the sealing cylinder 544.

[0062] When the exhaust fan 52 rotates, it drives the connecting rod 541 at the top of the exhaust fan 52 to rotate synchronously. Through the connection of the cross plate 542, the arc-shaped rotating block 543 rotates in the sealing cylinder 544. When the top inclined plane of the arc-shaped rotating block 543 contacts the bottom inclined plane of the arc-shaped baffle 548, under the sliding action of the dovetail slider 547 and the dovetail chute 546, the arc-shaped baffle 548 is pushed upward by the arc-shaped rotating block 543, exposing the exhaust hole 545, and the gas is discharged outside the air outlet cylinder 53.

[0063] By using the exhaust fan 52 to evacuate the inside of the reaction vessel 1, a negative pressure is generated inside the reaction vessel 1, the volume of the bubbles increases and they rise faster. The gas inside the bubbles bursts the bubbles, further improving the defoaming efficiency. The air inside the reaction vessel 1 is discharged to the outside through the exhaust assembly 54.

[0064] The remaining structure is the same as that of the second embodiment.

The shaft rod 321 drives the stirring blades 323 to rotate through a plurality of connecting parts 322 to stir and homogenize the glass liquid in the reaction vessel 1, so that the bubbles in the glass liquid flow in a circular shape during the stirring and homogenization process. When the shaft rod 321 rotates, it drives the short rod 324 and the long rod 325 to rotate, and guides the bubbles in the glass liquid to gather towards the center of the liquid surface in a circular shape through the bubble-introducing inclined rod 326 and the reinforcing inclined rod 327.

[0068] S3. According to the real-time liquid level of the glass liquid in the reaction vessel 1, a plurality of hollow balls 417 at the bottom of the arc-shaped bottom plate 416 move up and down through buoyancy, so that the E-shaped moving block 412 slides in the moving groove 411. The rotation rod 421 is driven to rotate by the rotation of the shaft rod 321, so that the thorns 423 on the deepening rod 422 pierce the bubbles gathered on the liquid surface.

[0069] S4. While the shaft rod 321 rotates, under the action of the planetary speed increaser 51, the exhaust fan 52 starts to work to evacuate the inside of the reaction vessel 1, generating a negative pressure inside the reaction vessel 1. The volume of the bubbles increases and they rise faster. The gas inside the bubbles bursts the bubbles. After the bubbles float out of the surface of the glass liquid, they burst and disappear, and the gas enters the sealing cylinder 544.

[0070] S5. When the exhaust fan 52 rotates, it drives the arc-shaped rotating block 543 to rotate within the sealing cylinder 544. When the top inclined plane of the arc-shaped rotating block 543 comes into contact with the bottom inclined plane of the arc-shaped baffle 548, under the action of the dovetail slider 547 and the dovetail chute 546, the arc-shaped baffle 548 is pushed upward by the arc-shaped rotating block 543, exposing the exhaust hole 545, allowing the gas to be discharged outside the air outlet cylinder 53;

[0071] S6. Repeat S2 - S5 until the bubbles in the glass liquid are completely broken, discharge the glass liquid from the reaction vessel 1, and turn off the drive motor 2 and the heater 312.
