Rolling equipment and method for producing microcrystalline glass with circulating cooling function

Abstract

The present invention discloses a rolling device and method for producing microcrystalline glass with a circulating cooling function, which relates to the technical field of glass production and includes a micro-vibration generating mechanism. The micro-vibration generating mechanism moves with the flow of coolant in the cavity of a rolling roller and generates a vibration force. The present invention transports coolant into the rolling roller through a circulating cooling component. After the coolant enters the cavity in the rolling roller, it flows from one end of the rolling roller close to a driving motor to one side of a coolant return pipe, and drives the micro-vibration generating mechanism to generate a vibration force. The vibration force is transmitted from the rolling roller to the glass liquid rolled by the rolling roller, so that the glass liquid is evenly rolled and formed at a faster speed under the influence of the micro-vibration force, which helps to more quickly roll the glass liquid into a microcrystalline glass semi-finished product, and can further improve the structural uniformity of the microcrystalline glass plate after rolling during the rolling process, while improving the flatness of the surface of the microcrystalline glass after rolling, further improving the quality of the finished product.

Description

Technical Field

[0001] The present invention relates to the technical field of glass production, and in particular to a rolling device and method for producing microcrystalline glass with a circulating cooling function. Background Art

[0002] There are several production processes for microcrystalline glass, and there are currently two main processes, one is the sintering method, and the other is the calendering production process. The calendering method is that the glass liquid is directly formed by a calendering machine and enters the crystallization kiln, without quenching and then heating, saving a lot of fuel and labor. The specific production process is: 1. The glass raw materials are weighed as required and poured into the mixer; 2. The mixed glass batch is added to the glass melting furnace; 3. The melted glass liquid enters the calendering machine for forming; 4. The formed glass plate enters the crystallization kiln for crystallization; 5. The crystallized microcrystalline plate passes through a thickness setting machine, a polishing machine, a bridge cutting machine and other cold processing to become the product required by the user.

[0003] In the prior art, in order to control the temperature of the molten glass during calendering, a coolant is usually introduced into the calendering roller to cool the calendering roller and the molten glass to a certain extent, so that the molten glass during calendering is controlled within a certain temperature range, so that better quality microcrystalline glass can be calendered, such as the calendering roller proposed in a production method of a grind-free and polish-free black transparent microcrystalline glass plate disclosed in the patent document with publication number "CN102603193A", but this calendering roller needs to be provided with water inlet and outlet holes at both ends of the roller; there is also a scheme in which a water inlet and outlet are provided at one end, such as a four-roller microcrystalline glass calender disclosed in the patent document with publication number "CN220149451U", but the above two schemes do not take into account the stability of the sealing connection structure between the calendering roller and the inlet and outlet pipes during continuous rotation, and local overflow is prone to occur when used for a long time.

[0004] Based on the above search and in combination with the prior art, it is found that the prior art only considers controlling the temperature of the molten glass, but it cannot improve the efficiency of calendering. When the calendering efficiency cannot be improved, the molten glass will accumulate (one side of the molten glass will inevitably be in a pile during calendering) on ​​one side of the calendering roller. When the temperature of the molten glass drops, slight condensation may occur in a certain area (especially the edge and the center position that first contacts the calendering roller), which is not conducive to improving the quality of microcrystalline glass. It may even lead to a decline in quality due to uneven distribution of internal materials or uneven surface due to micro-condensation. Therefore, a calendering device and method for producing microcrystalline glass with a circulating cooling function is needed. Summary of the invention

[0032] Second

[0033] A method for rolling microcrystalline glass production is applied to the above-mentioned rolling equipment for microcrystalline glass production with circulating cooling function, comprising the following steps:

[0034] First, start the drive motor and the circulation pump. The drive motor drives the calendering rollers to rotate through the reducer, and the two calendering rollers rotate synchronously and in opposite directions.

[0035] At the same time, the circulating pump transports the coolant in the cooling water tank to the coolant inlet pipe through the water delivery pipe and the first connecting pipe, and finally enters the cavity of the calendering roller through the coolant inlet pipe from the end of the coolant inlet pipe close to the driving motor;

[0036] The cooling liquid fills the cavity of the calendering roller and cools the calendering roller, thereby controlling the temperature of the calendering roller, thereby cooling the glass liquid while calendering, which is beneficial to improving the quality of the finished product of microcrystalline glass;

[0037] As the coolant flows from one end close to the driving motor to the other end close to the coolant return pipe in the cavity of the calendering roller, the coolant impacts the driven impeller. When the driven impeller is impacted, it rotates in the opposite direction to the rotation direction of the calendering roller, and drives the vibration bump to hit the vibration reed, so that the vibration reed generates vibration force.

[0038] The vibration force of the vibrating reed is transmitted to the molten glass through the calendering roller, so that the molten glass is evenly calendered at a faster speed under the influence of the micro-vibration force, which helps to calender the glass liquid more quickly. In addition, the structural uniformity of the calendered microcrystalline glass plate can be further improved during the calendering process, and the flatness of the surface of the calendered microcrystalline glass can be improved, thereby further improving the quality of the finished product.

[0039] The coolant after impacting the driven impeller is collected in the coolant return pipe and led out to the return cover, and finally flows back to the cooling water tank through the second connecting pipe, thus completing the recycling of the coolant.

[0040] In summary, the technical effects and advantages of the present invention are as follows:

[0041] 1. In the present invention, the cooling liquid is transported into the calendering roller by the circulating cooling assembly, so that the temperature of the calendering roller and the glass liquid is reduced. By controlling the flow rate, water inlet temperature, water outlet temperature and water flow rate of the cooling liquid, the temperature of the calendering roller and the glass liquid is controlled, thereby improving the quality of the calendered finished product;

[0042] At the same time, after the coolant enters the cavity inside the calendering roller, it flows from the calendering roller close to the end of the driving motor to the side of the coolant return pipe, and drives the micro-vibration generating mechanism to move, thereby generating a vibration force. The vibration force is transmitted from the calendering roller to the microcrystalline glass calendering body calendered by the calendering roller, so that the glass liquid is evenly calendered and formed at a faster speed under the influence of the micro-vibration force, which helps to more quickly calender the glass liquid into a microcrystalline glass semi-finished product, and in the calendering process, it can further improve the structural uniformity of the microcrystalline glass plate after calendering, and at the same time improve the flatness of the surface of the microcrystalline glass after calendering, thereby further improving the quality of the finished product.

[0043] 2. In the present invention, through the arrangement of the driven impeller, the vibrating reed and the striking vibration protrusion, when the driven impeller is impacted, it generates a rotation in the opposite direction to the rotation direction of the calendering roller, and drives the striking vibration protrusion to hit the vibrating reed, so that the vibrating reed generates a vibration force, and the vibration force of the vibrating reed is transmitted to the calendered glass liquid through the calendering roller, so that the glass liquid is affected by the micro-vibration force and is uniformly calendered into shape at a faster speed, thereby helping to calender the glass liquid into shape more quickly, and in the calendering process, it can further improve the structural uniformity of the microcrystalline glass plate after calendering, and at the same time improve the flatness of the surface of the microcrystalline glass after calendering, ultimately achieving the effect of further improving the quality of the finished product.

[0044] 3. In the present invention, by setting the sealing joint pipe fittings, the water supply pipe and the recovery pipe are connected with the coolant inlet pipe and the coolant return pipe respectively through the first connecting pipe, the reflux cover and the second connecting pipe, so that the coolant inlet pipe and the coolant return pipe can rotate synchronously with the calendering roller, and are used in conjunction with the first sealing connecting shaft and the second sealing connecting shaft, so that the sealing effect is better and more stable, and the stability of the sealing structure of the end connection is improved, so that after long-term use, there will be no local leakage when the coolant enters and is discharged, and the effect is good in actual use.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example: Reference Figure 1-Figure 8 The present invention provides a rolling device for producing microcrystalline glass with a circulating cooling function, comprising a device housing 1, to which two rolling rollers 2 distributed up and down are rotatably connected, and a driving motor 3 and a reducer 4 for driving the two rolling rollers 2 to rotate synchronously in opposite directions are installed on one side of the device housing 1;

[0057] A cavity is provided in the calendering roller 2, and an opening connecting the cavity with the outside is provided at one end of the calendering roller 2 away from the driving motor 3. A coolant inlet pipe 14 is provided in the calendering roller 2, and one end of the coolant inlet pipe 14 extends to a side of the calendering roller 2 close to the driving motor 3 and there is a gap between the coolant inlet pipe 14 and the inner wall of the calendering roller 2 for the coolant to enter the cavity of the calendering roller 2. A coolant reflux pipe 15 is provided at the opening of the calendering roller 2;

[0058] A micro-vibration generating mechanism is installed in the cavity of the calendering roller 2. The micro-vibration generating mechanism moves with the flow of the coolant in the cavity of the calendering roller 2 and generates a vibration force. The vibration force is transmitted from the calendering roller 2 to the micro-ceramic glass calendered body calendered by the calendering roller 2.

[0059] Among them, the end of the calendering roller 2 away from the driving motor 3 is equipped with a sealing joint pipe fitting that is rotatably connected to the coolant inlet pipe 14 and the coolant return pipe 15, and the sealing joint pipe fitting is fixed to the equipment housing 1;

[0060] A circulating cooling assembly is installed on the other side of the equipment housing 1. The circulating cooling assembly delivers coolant into the coolant inlet pipe 14 through a sealed joint pipe, and recovers the coolant at a coolant return pipe 15.

[0061] Based on the above structure, after the driving motor 3 is started, the driving motor 3 drives the calendering rollers 2 to rotate through the reducer 4, and the two calendering rollers 2 rotate synchronously and oppositely, so as to calender the glass liquid coming out of the kiln;

[0062] During calendering, the circulating cooling component delivers cooling liquid into the calendering roller 2, thereby reducing the temperature of the calendering roller 2 and the glass liquid. By controlling the flow rate, water inlet temperature, water outlet temperature and water flow rate of the cooling liquid, the temperature of the calendering roller 2 and the glass liquid is controlled, thereby improving the quality of the calendered finished product.

[0063] At the same time, after the coolant enters the cavity in the calendering roller 2, it flows from the calendering roller 2 close to the driving motor 3 to the side of the coolant return pipe 15, and drives the micro-vibration generating mechanism to move, thereby generating a vibration force. The vibration force is transmitted from the calendering roller 2 to the microcrystalline glass calendering body (i.e., the glass liquid during calendering) calendered by the calendering roller 2, so that the glass liquid is evenly calendered and formed at a faster speed under the influence of the micro-vibration force, which helps to more quickly calender the glass liquid into a microcrystalline glass semi-finished product (plate shape), and in the calendering process, it can further improve the structural uniformity of the microcrystalline glass plate after calendering, and at the same time improve the flatness of the surface of the microcrystalline glass after calendering, thereby further improving the quality of the finished product.

[0064] Furthermore, the micro-vibration generating mechanism includes:

[0065] A driven impeller 16, which is rotatably sleeved on the outside of the coolant inlet pipe 14 and driven to rotate by the water flow between the outer wall of the coolant inlet pipe 14 and the inner wall of the cavity of the calendering roller 2;

[0066] A vibration reed 17, wherein the vibration reed 17 is in an oblique Z shape on the cross section of the calendering roller 2, one end of the vibration reed 17 is fixed to the inner wall of the cavity of the calendering roller 2, and the other end of the vibration reed 17 extends toward the peripheral side close to the driven impeller 16;

[0067] The striking bump 18 is a protrusion with a circular cross section. The striking bump 18 is fixed to the peripheral side of the driven impeller 16, and when the striking bump 18 and the vibration reed 17 are in the same position, the striking bump 18 strikes the vibration reed 17 and causes the vibration reed 17 to vibrate.

[0068] Through the arrangement of the driven impeller 16, the vibrating reed 17 and the striking protrusion 18, when the driven impeller 16 is impacted, it rotates in the opposite direction to the rotation direction of the calendering roller 2, and drives the striking protrusion 18 to hit the vibrating reed 17, so that the vibrating reed 17 generates a vibration force, and the vibration force of the vibrating reed 17 is transmitted to the calendered glass liquid through the calendering roller 2, so that the glass liquid is affected by the micro-vibration force and is evenly calendered into shape at a faster speed, thereby helping to more quickly calender the glass liquid into shape, and in the calendering process, it can further improve the structural uniformity of the microcrystalline glass plate after calendering, and at the same time improve the flatness of the surface of the microcrystalline glass after calendering, ultimately achieving the effect of further improving the quality of the finished product.

[0069] Furthermore, the driven impeller 16 is a vortex impeller with high kinetic energy conversion efficiency (other impeller bodies suitable for this embodiment that flow with the coolant and have high power conversion efficiency may also be used), the maximum diameter of the driven impeller 16 is smaller than the inner diameter of the cavity of the calendering roller 2, the driven impeller 16 and the coolant inlet pipe 14 are coaxially arranged with the calendering roller 2, and the rotation direction of the driven impeller 16 is opposite to the rotation direction of the calendering roller 2, so that the driven impeller 16 can better rotate with the impact of the coolant, and the impact bump 18 can impact the vibration reed 17 faster, so as to improve the stability of the vibration force generated;

[0070] In order to ensure the continuous generation of vibration force, multiple vibration reeds 17 and vibration bumps 18 can be provided and distributed in a circular array along the axis of the calendering roller 2, so that multiple vibration reeds 17 and multiple vibration bumps 18 cooperate to generate continuous and uninterrupted vibration force.

[0071] In order to ensure that the vibration force can cover the entire area of ​​the calender roller 2 and make the vibration force consistent, multiple groups of vibration generating mechanisms are provided, and the multiple groups of vibration generating mechanisms are sequentially arranged and distributed along the calender roller 2, and the spacing between the multiple groups of vibration generating mechanisms increases sequentially from the output end of the coolant inlet pipe 14 to the side of the coolant return pipe 15;

[0072] In addition, by designing the shape of the vibration reed 17, the end of the vibration reed 17 close to the driven impeller 16 is inclined to one side, and the inclined side wall of the vibration reed 17 is tangent to the arc wall of the vibration protrusion 18. The contact length between the vibration protrusion 18 and the vibration reed 17 is less than one third of the overall length of the vibration reed 17. This can reduce the impact wear of the vibration protrusion 18 and the vibration reed 17 when they are in contact, and can reduce the interaction force between the two, so that the driven impeller 16 encounters less resistance when rotating, thereby ensuring smooth rotation.

[0073] Furthermore, the coolant inlet pipe 14 is plugged and fixed to the coolant return pipe 15 and the inner side of the calendering roller 2 through the support rod, and the coolant return pipe 15 is fixed to the inner side of the opening of the calendering roller 2;

[0074] Sealing joint fittings include:

[0075] A return cover 9, the outer wall of which is fixed to the equipment housing 1, and the return cover 9 is rotatably sleeved on the outer side of the coolant return pipe 15 through a first sealing connection shaft 19, and the return cover 9 is sealed and communicated with the coolant return pipe 15;

[0076] A first connecting pipe 10, the first connecting pipe 10 is fixedly passed through the side wall of the return cover 9 away from the coolant return pipe 15, and the first connecting pipe 10 is rotatably sealed and connected to one end of the coolant inlet pipe 14 through a second sealing connecting shaft 20;

[0077] The second connecting pipe 11 is fixed to one side of the return cover 9 and communicated with the return cover 9 .

[0078] Further, the circulating cooling component includes:

[0079] A cooling water tank 5, which is arranged on a side of the device housing 1 away from the drive motor 3;

[0080] A circulating pump 6 is fixed to the upper end of the cooling water tank 5, a water inlet of the circulating pump 6 is connected to the cooling water tank 5 through a pipeline, and a water outlet of the circulating pump 6 is located above the circulating pump 6;

[0081] A water supply pipe 7, the lower end of the water supply pipe 7 is fixed and connected to the water outlet end of the upper end of the circulation pump 6, and the upper part of the water supply pipe 7 is fixed and connected to the coolant inlet pipe 14;

[0082] The recovery pipe 8 , the upper part of the recovery pipe 8 is fixed and communicated with the coolant return pipe 15 , and the lower end of the recovery pipe 8 is fixed and communicated with the cooling water tank 5 .

[0083] By setting the sealing joint pipe fittings, the water supply pipe 7 and the recovery pipe 8 are connected with the coolant inlet pipe 14 and the coolant return pipe 15 respectively through the first connecting pipe 10 and the reflux cover 9 and the second connecting pipe 11, so that the coolant inlet pipe 14 and the coolant return pipe 15 can rotate synchronously with the calendering roller 2, and are used in conjunction with the first sealing connecting shaft 19 and the second sealing connecting shaft 20. The sealing effect is more stable, and the stability of the sealing structure of the end connection is improved, so that after long-term use, there will still be no local leakage when the coolant enters and is discharged, and the effect is good in actual use.

[0084] In addition, in order to further facilitate the later maintenance of the equipment, the calendering roller 2 is configured as an assembleable roller body in the present invention, such as Figure 4-Figure 5 As shown, it includes a long cylindrical main roller body and a detachable roller head 13, wherein both the main roller body and the detachable roller head 13 are provided with shaft columns, which are rotatably connected to the equipment housing 1 through a support bearing 12, and the shaft column of the main roller body is also transmission-connected to the output end of the reducer 4, and an installation and maintenance port 21 adapted to the detachable roller head 13 is provided at one end of the main roller body close to the detachable roller head 13, so as to install the detachable roller head 13 and internal components, and subsequently disassemble the detachable roller head 13 to disassemble or repair the components inside the roller body, and the detachable roller head 13 and the main roller body are fixed by a connection method commonly used in the prior art and applicable to the present embodiment, such as fixing by bolts.

[0085] The present invention also provides a method for rolling production of microcrystalline glass, which is applied to the above-mentioned rolling equipment for producing microcrystalline glass with a circulating cooling function, and comprises the following steps:

[0086] First, the driving motor 3 and the circulating pump 6 are started, and the driving motor 3 drives the calendering roller 2 to rotate through the reducer 4, and the two calendering rollers 2 rotate synchronously and oppositely;

[0087] At the same time, the circulating pump 6 transports the coolant in the cooling water tank 5 to the coolant inlet pipe 14 through the water delivery pipe 7 and the first connecting pipe 10, and finally enters the cavity of the calendering roller 2 through the coolant inlet pipe 14 from the end of the coolant inlet pipe 14 close to the driving motor 3;

[0088] The cooling liquid fills the cavity of the calendering roller 2 and cools the calendering roller 2, thereby controlling the temperature of the calendering roller 2, thereby cooling the glass liquid while calendering, which is beneficial to improving the quality of the finished product of the microcrystalline glass;

[0089] As the coolant flows from one end close to the driving motor 3 to the other end close to the coolant return pipe 15 in the cavity of the calendering roller 2, the coolant impacts the driven impeller 16. When the driven impeller 16 is impacted, it rotates in the opposite direction to the rotation direction of the calendering roller 2, and drives the vibration bump 18 to hit the vibration reed 17, so that the vibration reed 17 generates a vibration force.

[0090] The vibration force of the vibrating reed 17 is transmitted to the calendered glass liquid through the calendering roller 2, so that the glass liquid is evenly calendered and formed at a faster speed under the influence of the micro-vibration force, thereby helping to calender the glass liquid more quickly, and in the calendering process, the structural uniformity of the calendered microcrystalline glass plate can be further improved, and the flatness of the surface of the calendered microcrystalline glass can be improved, thereby further improving the quality of the finished product;

[0091] The coolant after impacting the driven impeller 16 is collected in the coolant return pipe 15 and led to the return cover 9, and finally flows back to the cooling water tank 5 through the second connecting pipe 11, completing the recycling of the coolant;

[0092] It should be further explained that in order to ensure that the coolant can be recycled, the present invention should also be provided with a filter for filtering the coolant, a refrigerator for cooling the coolant after use and other mechanisms (not shown in the figures). The filter and the refrigerator are both existing equipment commonly used in the prior art and suitable for this embodiment to ensure the effect of circulating cooling.

[0093] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
