[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] Due to insufficient stirring of the glass liquid and uneven proportioning, streaks appear, which affects product quality.

[0031] The disclosed embodiment of the present application provides a glass liquid stirring tank, comprising: a stirring tank 10, a bracket 30, a lifting mechanism 40 and a rotating stirring mechanism 50; a heating part 20 is provided on the side wall 13 of the stirring tank 10, and the heating part 20 is located between the notch of the stirring tank 10 and the tank bottom 11; the bracket 30 has a workbench 31, and the workbench 31 is arranged at a distance from the notch of the stirring tank 10; the lifting mechanism 40 is arranged on the end surface of the workbench 31 away from the stirring tank 10, and the lifting mechanism 40 includes a first driving member 41 and a lifting member 42, and the first driving member 41 drives the lifting member 42 away from or close to the workbench 31; the rotating stirring mechanism 50 is connected to the lifting member 42, and the rotating stirring mechanism 50 includes a second driving member 51 and a stirring member 52; one end of the stirring member 52 is transmission-connected to the second driving member 51, and the other end extends into the stirring tank 10 and corresponds to the position of the heating part 20, and the other end of the stirring member 52 is provided with a stirring part 521;

[0032] The lifting member 42 of the lifting mechanism 40 drives the rotary stirring mechanism 50 to lift and lower, so that the stirring portion 521 lifts and lowers between the slot and the slot bottom 11 , and the second driving member 51 of the rotary stirring mechanism 50 drives the stirring member 52 to rotate.

[0033] It can be understood that the stirring tank 10 has an accommodating space and can be a rectangular structure for temporarily containing molten glass, and cooperates with the lifting mechanism 40 and the rotating stirring mechanism 50 so that the glass can be evenly heated and mixed in the stirring tank 10.

[0034] The heating unit 20 is installed on the side wall 13 of the stirring tank 10, and is used to heat the glass liquid in the stirring tank 10, so that the glass liquid in the stirring tank 10 maintains a certain temperature, which helps to make the components of the glass liquid mix more evenly during the stirring process. The heating unit 20 can be a resistance wire embedded in the side wall 13 of the stirring tank 10, or a heating plate set on the inner side wall 13 of the stirring tank 10, or an electric heating brick, which generates heat through electric current to keep the glass liquid at a desired temperature.

[0035] The support 30 is used to support the frame of the entire equipment structure, and is usually made of a strong high temperature resistant material, such as a metal material, and can be stainless steel. The support 30 can be arranged adjacent to the stirring tank 10 so that the workbench 31 is placed above the stirring tank 10.

[0036] One possible implementation method is that the bracket 30 includes a plurality of legs and a workbench 31. The legs are fixedly arranged on both sides of the mixing tank 10. The upper end of the legs is fixedly provided with a workbench 31. The workbench 31 has a load-bearing capacity and is used to install a lifting mechanism 40 and a rotating stirring mechanism 50, etc.

[0037] The lifting mechanism 40 is arranged on the workbench 31, the first driving member 41 can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, and the lifting member 42 is a workpiece that is transmission-connected to the first driving member 41 and can be lifted and lowered under the driving action of the first driving member 41. For example, a nut arranged on a lead screw 43 of an electric cylinder, when the motor is started and drives the lead screw 43 to rotate along its own axis, the nut reciprocates along the length direction of the lead screw 43.

[0038] The rotary stirring mechanism 50 includes a second driving member 51 and a stirring member 52. The second driving member 51 can be a motor, which is fixed on the lifting member 42 and connected to one end of the stirring member 52 through a coupling. The other end of the stirring member 52 extends to the inside of the stirring tank 10 and corresponds to the position of the heating part 20. The stirring part 521 at the end of the stirring member 52 can be an integral spiral, or it can be formed by a plurality of stirring blades arranged at intervals along the circumference of the stirring member 52. The stirring member 52 can rotate under the drive of the motor so that the stirring part 521 stirs the glass liquid.

[0039] During the operation, the glass liquid to be fully stirred flows into the stirring tank 10. At this time, the heating part 20 is started, and the local area of ​​the stirring tank 10 where the heating part 20 is provided is heated and heated. The first driving member 41 drives the lifting member 42 to move up and down, so that the stirring member 52 stirs at different depths in the stirring tank 10. At the same time, the second driving member 51 drives the stirring member 52 to rotate, and the spiral blades of the stirring part 521 rotate accordingly to fully mix the glass liquid.

[0040] Since the stirring part 521 can both rotate and rise and fall in the heating area formed by the electric heating of the heating part 20, it can ensure that the glass liquid in the stirring tank 10 can be evenly mixed at all heights, thereby avoiding the occurrence of streak defects and improving product quality.

[0041] In some embodiments, the mixing tank 10 is a long strip containing tank, including a side wall 13, a tank bottom 11 and an upper cover 12, which together enclose a containing space, and the mixing tank 10 is provided with an inlet 14 at one end along the length direction and an outlet 15 at the other end;

[0042] The slot is arranged opposite to the slot bottom 11, the upper cover 12 is arranged on the slot and covers the slot, the upper cover 12 is provided with an escape opening 121, and the opening diameter of the escape opening 121 is larger than the stirring part 521;

[0043] The glass liquid flows into the heating part 20 from the inlet 14 , and flows out from the outlet 15 after being stirred by the stirring element 52 .

[0044] It can be understood that the containing space is used to contain the glass liquid to be fully stirred, and the glass liquid enters the stirring tank 10 from the inlet 14, and after being heated and stirred, flows into the molding equipment through the outlet 15. The side wall 13, the tank bottom 11 and the upper cover 12 of the stirring tank 10 are all built with refractory bricks, and the refractory bricks can be silica bricks, aluminosilicate bricks or fused high zirconium bricks.

[0045] The upper cover 12 is provided with an escape opening 121, which enables the stirring part 521 to move up and down, rotate and stir in the stirring tank 10 without touching the upper cover 12. At the same time, the escape opening 121 provides an escape space for the stirring part 521 to be raised and lowered, so as to maximize the lifting range of the lifting part, thereby fully stirring the glass liquid.

[0046] In some embodiments, a portion of the tank bottom 11 close to the outlet 15 is inclined toward the upper cover 12 to form an inclined slope and reduce the opening size of the outlet 15 .

[0047] It can be understood that since the outlet 15 has an inclined slope, the outflow speed of the glass liquid is slowed down, the residence time of the glass liquid in the stirring tank 10 is increased, and the stirring time of the glass liquid is extended.

[0048] In some embodiments, the side wall 13 of the stirring tank 10 is built with refractory bricks, and the heating part 20 is an electric heating brick, which is mixed with the refractory bricks and is located in the middle of the side wall 13 .

[0049] It is understandable that the refractory bricks may be fused high-zirconium bricks, which are resistant to high temperatures, corrosion, and thermally stable, and also have high mechanical strength, thus being able to extend the service life of the stirring tank 10 .

[0050] The electric heating bricks are made of tin oxide electrode bricks. Tin oxide has good conductivity and high temperature resistance, and can maintain structural stability at high temperatures.

[0051] Among them, tin oxide electrode bricks can be used as electrodes and built together with refractory bricks on the side wall 13 of the stirring tank 10. The glass liquid near the electrode bricks is heated by electric current to achieve the effect of local precise heating. Since the positions of the stirring part 521 and the heating part 20 correspond to each other, the glass liquid in the stirring tank 10 can be locally heated and stirred, thereby improving the accuracy of the heating area in the stirring tank 10, saving energy and also achieving the effect of uniformly stirring the glass liquid.

[0052] In some embodiments, there are at least two groups of electric heating bricks, each group of electric heating bricks is arranged on opposite side walls 13, and each group of electric heating bricks is at least two pieces arranged in parallel, so that the two groups of electric heating bricks arranged oppositely form a heating area; the electric heating bricks are provided with a wiring part for connecting cables to supply power and heating through the cables.

[0053] It can be understood that in order to improve the heating efficiency of the glass liquid in the stirring tank 10 and accurately heat the stirring area of ​​the stirring part 521, the electric heating bricks are arranged into at least two groups. The electric heating bricks can be tin oxide electrode bricks, and are relatively arranged to completely cover the stirring area of ​​the stirring part 521, so that the stirring area can be accurately heated, providing temperature guarantee for uniform mixing of the glass liquid, thereby eliminating streak defects.

[0054] The electric heating bricks can be arranged in such a way that when the side wall 13 is built, the electric heating bricks are mixed with the refractory bricks and built together. A groove of appropriate size can also be pre-cut on the side wall 13 of the built stirring tank 10 to accommodate the electric heating bricks. The depth and width of the groove can be determined according to the specifications of the electric heating bricks to ensure that the surface of the electric heating bricks after installation is flush with the inner side wall 13 of the stirring tank 10. The electric heating bricks are fixed in the groove using refractory cement or other high temperature resistant materials to ensure the stability of the electric heating bricks under high temperature conditions.

[0055] A high temperature resistant cable is used to connect the wiring part of the electric heating bricks, and the two groups of electric heating bricks are respectively connected to an external power supply, and are also connected to a current and voltage regulating device to adjust the heating power according to actual needs.

[0056] A plurality of assembly holes may also be provided on the side wall 13 of the stirring tank 10. The assembly holes are arranged longitudinally from the tank bottom 11 to the slot mouth. Temperature sensors are installed through the assembly holes. The temperature sensors are used to detect the temperature of the glass liquid at different heights in the stirring tank 10, and the heating power of the electric heating bricks is automatically adjusted through a control system such as a PLC to maintain the temperature of the glass liquid.

[0057] For example, by arranging two groups of tin oxide electrode bricks relatively on the side wall 13 of the stirring tank 10 and connecting them through high-temperature resistant cables to heat the glass liquid, uniform heating of the glass liquid can be achieved, and the heating efficiency can be improved. At the same time, the structure of the heating system is simplified, and the stability and safety are enhanced. Combined with the lifting, lowering and rotating stirring of the stirring part 521, the glass liquid can be stirred fully and evenly, achieving the effect of eliminating streaks.

[0058] In some embodiments, the stirring portion 521 is a spiral stirring belt having an end surface extending along the circumference of the stirring member 52 .

[0059] It can be understood that the spiral stirring belt has an end surface extending along the circumference of the stirring element 52, and the end surface is divided into an upper end surface and a lower end surface that are arranged opposite to each other.

[0060] In the process of the stirring part 521 reciprocatingly rising and falling and rotating and stirring, when the stirring part 521 is raised, the upper end surface of the spiral stirring belt can lift the glass liquid at the bottom 11 of the stirring tank 10 to the groove mouth; when the stirring rod is lowered, the lower end surface of the spiral stirring belt can rotate and press the glass liquid at the groove mouth of the stirring tank 10 toward the bottom 11 of the tank, thereby achieving a sufficient stirring effect and mixing the glass liquid evenly.

[0061] In some embodiments, the stirring portion 521 is detachably connected to the end of the stirring member 52 .

[0062] It is understandable that during long-term use, condensation will be attached to the stirring part 521, which may be due to impurities in the glass liquid, incompletely melted raw materials or sediments after cooling. The presence of condensation affects the quality of the glass liquid, and the stirring part 521 needs to be cleaned regularly. Therefore, the stirring part 521 and the stirring member 52 are set to be detachably connected. The detachable connection method can be to respectively set internal and external thread structures at the connection position of the stirring part 521 and the stirring member 52, and the two are detachably connected through the internal and external thread structures.

[0063] The detachable connection method can also be that a flange structure is respectively provided on the stirring part 521 and the stirring element 52, and the two are connected at the connecting position through the flange structure, and mounting holes are respectively provided on the flange structure, and the detachable connection between the stirring part 521 and the stirring element 52 is realized by bolts passing through the mounting holes.

[0064] As the first driving member 41 drives the stirring member 52 to rise, the stirring portion 521 is allowed to escape from the stirring tank 10 at the position of the avoidance opening 121. The stirring portion 521 can be removed for maintenance and condensate cleaning, and a new stirring portion 521 can be directly replaced to work in the stirring tank 10 to avoid streak defects caused by the inclusion of condensate in the glass liquid.

[0065] In some embodiments, the lifting mechanism 40 also includes a screw 43, which is vertically arranged on the workbench 31. The driving end of the first driving member 41 is transmission-connected to the screw 43 so that the screw 43 can rotate along its axis. The lifting member 42 is assembled on the screw 43 through a threaded structure and moves between the upper and lower ends of the screw 43 as the screw 43 rotates.

[0066] It is understandable that the lifting mechanism 40 may be a ball screw 43 , and the first driving member 41 may be a motor. The lifting member 42 may be assembled on a nut on the ball screw 43 .

[0067] A fixing frame 80 is provided on the outer side of the lead screw 43. The fixing frame 80 is arranged on the workbench 31. The lead screw 43 is vertically assembled in the fixing frame 80 and can rotate in the fixing frame 80. Two upper and lower opposite end faces of the fixing frame 80 are respectively provided with bearing seats. Both ends of the lead screw 43 are respectively assembled in the bearing seats to realize the smooth rotation of the lead screw 43. A first driving member 41 is installed at the upper end of the fixing frame 80. The first driving member 41 can be a servo motor. The output end of the servo motor is connected to one end of the lead screw 43 to drive the lead screw 43 to rotate. The nut assembled on the lead screw 43 rises or falls following the forward rotation or reverse rotation of the lead screw 43.

[0068] In some embodiments, a mounting frame 60 is further included. The mounting frame 60 is fixedly connected to the lifting member 42 , and at least one rotating stirring mechanism 50 is installed on the mounting frame 60 .

[0069] It can be understood that the mounting frame 60 is fixedly mounted on the lifting member 42, and the fixed mounting method can be welding or bolt connection. The mounting frame 60 moves synchronously with the lifting member 42 when the lead screw 43 rises or falls, so as to realize the movement of the mounting frame 60 relative to the workbench 31. One implementation method is that the mounting frame 60 is set at the lower end of the workbench 31, and the mounting frame 60 moves closer to or away from the workbench 31 following the movement of the lifting member 42.

[0070] At least one spiral stirring mechanism is installed on the mounting frame 60, and multiple spiral stirring mechanisms can also be installed at intervals. With the increase of spiral stirring mechanisms, the glass liquid can be stirred fully and evenly. One implementation method is that the second driving member 51 of the rotating stirring mechanism 50 is arranged on the upper side of the mounting frame 60, that is, away from the side of the stirring tank 10, and the stirring member 52 is arranged on the lower side of the mounting frame 60, that is, close to the side of the stirring tank 10 and one end of the stirring part 521 extends into the stirring tank 10, and the stirring member 52 is connected to the second driving member 51 in transmission connection. The transmission connection method can be to use a coupling to achieve the transmission connection.

[0071] In some embodiments, a heat-insulating layer 70 is further included, which is wrapped around the outer side of the stirring tank 10 , and the heat-insulating layer 70 also includes a heat-insulating sub-layer 71 , which is placed above the avoidance opening 121 and covers the gap between the stirring element 52 and the avoidance opening 121 .

[0072] It is understandable that the insulation layer 70 is arranged outside the glass liquid stirring tank 10 to ensure the internal temperature of the stirring tank 10 is stable and reduce heat loss. The material of the insulation layer 70 can be aluminum silicate fiber blanket, perlite, microporous calcium silicate, ceramic fiber, rock wool, etc.

[0073] Alumina silicate fiber blanket is a lightweight, flexible refractory material with excellent thermal insulation and high temperature resistance, and the maximum operating temperature can reach 1260°C. It can significantly reduce the heat loss of the mixing tank 10, improve energy efficiency, and facilitate installation and maintenance. Perlite is a natural mineral that forms a lightweight, porous structure after expansion treatment and has good thermal insulation properties. It can effectively isolate the influence of the external environment on the internal temperature of the mixing tank 10, and its lightweight characteristics reduce the overall weight of the mixing tank 10.

[0074] Microporous calcium silicate is a microporous structure material with calcium silicate as the main component, which has excellent thermal insulation performance and high temperature resistance. It can provide efficient thermal insulation effect, reduce heat loss, and has a certain mechanical strength, which is suitable for a variety of environments.

[0075] Ceramic fiber is a high temperature resistant material made of high purity alumina and silica with very low thermal conductivity. It not only provides efficient thermal insulation, but also has good chemical stability and thermal shock resistance, making it suitable for long-term use under high temperature conditions.

[0076] Rock wool is a fiber material drawn from natural rocks such as basalt after melting, and has good thermal insulation and fire resistance. It can effectively reduce heat loss, and its fire resistance provides additional safety for the mixing tank 10.

[0077] By providing the heat insulation layer 70, the heat loss of the stirring tank 10 can be reduced, thereby reducing energy consumption and improving energy utilization efficiency. The heat insulation layer 70 can also maintain the stability of the temperature inside the stirring tank 10. It can also reduce the temperature difference between the inside and outside of the stirring tank 10, which helps to reduce the damage to the equipment caused by thermal stress, thereby extending the service life of the stirring tank 10. The heat insulation layer 70 can not only prevent the external environment temperature from affecting the inside of the stirring tank 10, but also reduce the risk of scalding of the staff.

[0078] The heat-insulating sublayer 71 is made of rock wool or aluminum silicate fiber blanket. The heat-insulating sublayer 71 can be easily moved to cover the gap between the stirring element 52 and the avoidance opening 121 to prevent heat loss.
