A tempered glass production and processing device

Abstract

The present invention relates to a production and processing device for tempered glass. When removing air bubbles from molten glass during the production process, in the first stage, the inner liquid cylinder is first controlled to be in a dynamic state of swinging back and forth continuously, so that the molten glass inside it is constantly oscillated, which is convenient for assisting and accelerating the overflow of some air bubbles. At the same time, with the cooperation of the suction pipe, air bubbles can be effectively adsorbed outward, forming a certain micro-negative pressure state above the molten glass, effectively ensuring the discharge of air bubbles. At the same time, with the setting of the semi-sealed ball rod, in the second stage, after each oscillation, the inner liquid cylinder is controlled to reset and be in a sealed state. At this time, some air bubbles overflow. Due to the high temperature of the molten glass, the gas will continuously expand, causing the bottom of the contact ball to gradually deform upward and pushing the colored solution to move upward to the part of the semi-sealed ball rod outside the pair-hole long cover. At this time, the staff can control the inner liquid cylinder to rotate again, unsealing the exhaust hole, and at the same time making the suction pipe suck air outward, effectively removing the overflowing air.

Description

Technical Field

[0001] A processing device related to the present invention, particularly a production and processing device for tempered glass applied to the field of tempered glass. Background Art

[0002] The normal production process of flat glass is as follows: raw materials are melted at high temperature to form glass liquid; when the glass liquid cools to a temperature range suitable for mechanical processing, it is rolled to form a flat shape; and then it is annealed after cooling. For tempered glass, an additional strengthening step needs to be added at the end of the above process. Specifically, after obtaining ordinary glass of a determined size, it is heated to near the glass softening point of about 650°C - 700°C, and then high-pressure air flows are blown on both sides of the glass simultaneously to rapidly cool it, forming a stress layer. However, when the raw materials are melted at high temperature to form glass liquid, air often exists inside, forming bubbles. When these bubbles are not removed, it is easy to cause small holes inside the finished product, affecting the strength of the glass. In the prior art, generally, clarifying agents are used to discharge the vast majority of bubbles in the glass liquid. However, the decomposition of the clarifying agents brings some bubbles with even smaller sizes. These bubbles do not combine with the bubbles decomposed from the glass raw materials and are thus difficult to be discharged.

[0003] To solve the above problems, the Chinese utility model patent CN201620206215.3 specification discloses "Bubble Absorption System for Glass Liquid and Glass Production Line", which uses a temperature control device to control the temperature of the glass liquid in the absorption tank and controls the gas pressure in the gas space above the absorption tank through an air inflation and pressurization device, so as to facilitate the control of the temperature, pressure, and atmosphere environment in the absorption tank, making the remaining bubbles in the glass liquid easier to be absorbed (such as chemical absorption and / or physical absorption) in the glass liquid, and facilitating the improvement of the quality of glass products.

[0004] However, in the above method, during the air inflation and pressurization process, it is very easy for the gas to enter the glass liquid due to improper control of temperature, pressure, and atmosphere environment, resulting in an increase in the amount of bubbles. Summary of the Invention

[0005] Aiming at the above prior art, the technical problem to be solved by the present invention is that in the prior art, the method of removing bubbles by air inflation and pressurization is very likely to cause gas backflow, resulting in an increase rather than a decrease in the amount of bubbles in the glass liquid.

[0006] To solve the above problems, the present invention provides a production and processing device for tempered glass, which includes a bottom plate. A plurality of pairs of brackets are fixedly connected to the upper end of the bottom plate. The upper end of each pair of brackets is connected with a double-layer cylinder. The left and right ends of the double-layer cylinder are respectively connected with a liquid inlet pipe and a liquid discharge pipe. The liquid inlet pipe and the liquid discharge pipe fixedly penetrate through the upper end of the bracket and communicate with the inside of the double-layer cylinder. The double-layer cylinder includes an outer shell, an inner liquid cylinder located inside the outer shell, and a lower convex platform fixedly connected to the lower end of the inner liquid cylinder. A plurality of uniformly distributed exhaust holes are drilled at the upper end of the inner liquid cylinder. An air suction pipe is fixedly connected to the upper end of the outer shell. The air suction pipe communicates with the inside of the outer shell. A pre-rotation long hole is drilled at the lower end of the outer shell. The lower convex platform penetrates through the pre-rotation long hole. Positioning plates are fixedly connected to the edges of the front and rear upper ends of the bottom plate. Electric push rods are installed at one end of the two positioning plates close to each other. A middle moving bar is fixedly connected between the extending ends of the two electric push rods. The middle moving bar is located directly below a plurality of double-layer cylinders. Two pairs of position control components are fixedly connected between the front and rear ends of the lower convex platform and the middle moving bar.

[0007] In the above production and processing device for tempered glass, the double-layer cylinder is constantly in a dynamic state of swinging back and forth, causing the glass liquid inside it to oscillate continuously, which is convenient for assisting and accelerating the overflow of some bubbles. At the same time, with the cooperation of the air suction pipe, it can effectively adsorb bubbles outward, forming a certain micro-negative pressure state above the glass liquid, effectively ensuring the discharge of bubbles.

[0008] As a further improvement of the present application, the opening cross-section of the pre-rotation long hole is 30-60°, the transverse span of the lower convex platform is smaller than the cross-sectional span of the inner liquid cylinder, and the cross-sectional span of the lower convex platform is 1 / 3-1 / 2 of the transverse span of the pre-rotation long hole.

[0009] As a further improvement of the present application, the air suction pipe includes an air-gathering cover fixedly connected to the upper end of the outer shell and a guide pipe fixedly connected to the upper end of the air-gathering cover. The air-gathering cover has a shape like a chime bell.

[0010] As a further improvement of the present application, the position control component includes two fixed rope columns respectively fixedly connected to the left and right ends of the middle moving bar and a pull rope fixedly connected to the outer end of the lower convex platform. The lower end of the pull rope is sleeved on the fixed rope column.

[0011] As a further improvement of the present application, the pull rope is a non-elastic structure, and when the lower convex platform maintains a vertical state, the pull ropes on the two pairs of position control components are both in a vertical state.

[0012] As another improvement of the present application, a pair-hole long cover is also fixedly connected to the upper end of the outer shell. A plurality of exhaust holes are located in the middle of the upper end of the inner liquid cylinder. A plurality of semi-sealed ball rods respectively corresponding to the plurality of exhaust holes are fixedly connected to the pair-hole long cover. The upper end of the semi-sealed ball rod fixedly penetrates through the pair-hole long cover and extends outside the pair-hole long cover. The lower end of the semi-sealed ball rod abuts against the exhaust hole.

[0013] As another improvement supplement of the present application, the semi-sealed ball rod includes a contact ball contacting the exhaust hole and an extension rod fixedly connected to the upper end of the contact ball. The upper end of the extension rod extends outside the hole length cover, and the extension rod is communicated with the contact ball. The contact ball includes a fixed ball shell and a moving arc plate fixedly connected to the lower end of the fixed ball shell. The contact part of the semi-sealed ball rod and the exhaust hole is located on the fixed ball shell.

[0014] As another improvement supplement of the present application, the contact ball is saturated and filled with a colored solution. The moving arc plate is a high-temperature resistant elastic sealing structure, and the fixed ball shell is a hard structure.

[0015] As another improvement supplement of the present application, the part of the extension rod located inside the hole length cover is an elastic structure, and the part of the extension rod located at the upper end of the hole length cover is a hard structure.

[0016] In summary, when removing bubbles, in the first stage, first control the inner liquid cylinder to be constantly in a dynamic state of swinging back and forth, so that the internal glass liquid oscillates continuously, which is convenient for assisting and accelerating the overflow of some bubbles. At the same time, with the cooperation of the suction pipe, bubbles can be effectively adsorbed outwards, forming a certain micro-negative pressure state above the glass liquid, effectively ensuring the discharge of bubbles. At the same time, with the setting of the semi-sealed ball rod, in the second stage, after each oscillation, control the inner liquid cylinder to reset and be in a sealed state. At this time, some bubbles overflow. Due to the high temperature of the glass liquid, the gas will continuously expand, causing the bottom of the contact ball to gradually deform upwards, and pushing the colored solution to move upwards to the part of the semi-sealed ball rod outside the hole length cover. At this time, the staff can control the inner liquid cylinder to rotate again, unseal the exhaust hole, and at the same time make the suction pipe suck air outwards, effectively removing the overflowing air.

Specific embodiments

[0029] The following will describe the two embodiments of the present application in detail with reference to the accompanying drawings.

[0030] The first embodiment:

[0031] Figure 1 As shown, a tempered glass production and processing device includes a bottom plate 1, and a plurality of pairs of brackets 2 are fixedly connected to the upper end of the bottom plate 1. A double-layer cylinder 4 is connected to the upper end of each pair of brackets 2. The left and right ends of the double-layer cylinder 4 are respectively connected with a liquid inlet pipe 31 and a liquid discharge pipe 32. The liquid inlet pipe 31 and the liquid discharge pipe 32 fixedly penetrate through the upper end of the bracket 2 and are communicated with the inside of the double-layer cylinder 4.

[0032] Please refer to Figures 2-3 , the double-layer cylinder 4 includes an outer shell 41, an inner cylinder 42 located inside the outer shell 41, and a lower convex platform 43 fixedly connected to the lower end of the inner cylinder 42. A plurality of uniformly distributed exhaust holes 401 are drilled in the upper end of the inner cylinder 42.

[0033] Please refer to Figure 4The air intake pipe 52 is fixedly connected to the upper end of the outer shell 41, and the air intake pipe comprises a gas collecting cover 51 fixed to the upper end of the outer shell 41 and an air guide pipe 52 fixedly connected to the upper end of the gas collecting cover 51. The gas collecting cover 51 is a bell-shaped structure, and the air intake pipe is directly connected to the external air intake device. When the air intake device is working, a certain micro-negative pressure can be presented in the inner liquid cylinder 42, so that the overflowed air is discharged in time, and at the same time, the bubbles in the glass liquid can be assisted to overflow upward, thereby achieving the effect of removing bubbles; the air intake pipe is communicated with the inside of the outer shell 41, and a pre-rotation long hole is cut out at the lower end of the outer shell 41. The lower boss 43 runs through the pre-rotation long hole, and the edges of the front and rear upper ends of the bottom plate 1 are fixedly connected to a positioning plate 61. An electric push rod 62 is installed at one end of the two positioning plates 61 close to each other. A middle moving bar 63 is fixedly connected between the elongated ends of the two electric push rods 62. The middle moving bar 63 is located just below the multiple double-layer cylinders 4, and two pairs of position control components are fixedly connected between the front and rear ends of the lower boss 43 and the middle moving bar 63.

[0034] When the lever 43 is in the upright position, the pull rope 71 is in the upright position, and the pull rope 71 is in the upright position, so that the lever 43 is in the upright position and the pull rope 71 is in the upright position.

[0035] like Figure 5 The cross-section of the opening of the pre-rotation long hole is 30-60°, the lateral span of the lower boss 43 is smaller than the cross-sectional span of the inner liquid cylinder 42, and the cross-sectional span of the lower boss 43 is 1 / 3-1 / 2 of the lateral span of the pre-rotation long hole, so that the rotation amplitude of the inner liquid cylinder 42 is limited, which can make the internal glass liquid discharge dynamic, and at the same time not easily make the turbulence amplitude too large, effectively preventing air from entering the glass liquid due to excessive oscillation amplitude.

[0036] In the above-mentioned tempered glass production and processing equipment, the double-layer cylinder 4 is constantly in a back-and-forth swinging state, causing the glass liquid inside to continuously vibrate, which is convenient for assisting and accelerating the overflow of some bubbles. At the same time, with the action of the suction pipe, it can effectively adsorb bubbles to the outside, so that a certain micro-negative pressure state is formed above the glass liquid, effectively ensuring the discharge of bubbles.

[0037] Second implementation method:

[0038] This embodiment adds the following content on the basis of the first implementation manner, specifically as follows

[0039] As Figures 6-7 shown, a hole-aligning long cover 8 is also fixedly connected to the upper end of the outer shell 41. A plurality of exhaust holes 401 are located in the middle of the upper end of the inner liquid cylinder 42. As Figure 8 , a plurality of semi-sealed ball rods 9 respectively corresponding to the plurality of exhaust holes 401 are fixedly connected to the hole-aligning long cover 8. The upper ends of the semi-sealed ball rods 9 fixedly penetrate through the hole-aligning long cover 8 and extend outside the hole-aligning long cover 8. The lower ends of the semi-sealed ball rods 9 are in contact with the exhaust holes 401.

[0040] It should be noted that one end of the hole-aligning long cover 8 is fixedly connected and communicated with the gas-accumulating cover 51.

[0041] When the inner liquid cylinder 42 rotates, the relative positions of the exhaust holes 401 continuously change, causing the exhaust holes 401 to continuously repeat the process of being sealed by the semi-sealed ball rods 9 and the mouth parts being partially separated from the semi-sealed ball rods 9. When separated, the gas inside the inner liquid cylinder 42 can overflow.

[0042] Please refer to Figure 9 , the semi-sealed ball rod 9 includes a contact ball in contact with the exhaust hole 401 and an extension rod 92 fixedly connected to the upper end of the contact ball. The upper end of the extension rod 92 extends outside the hole-aligning long cover 8, and the extension rod 92 is communicated with the contact ball. The contact ball includes a fixed ball shell 911 and a moving arc piece 912 fixedly connected to the lower end of the fixed ball shell 911. The fixed ball shell 911 is a rigid structure. The contact part of the semi-sealed ball rod 9 and the exhaust hole 401 is located on the fixed ball shell 911, effectively ensuring the relatively stable contact between the semi-sealed ball rod 9 and the exhaust hole 401, and it is not easy to generate a gap with the exhaust hole 401 due to reasons such as air pressure. The contact ball is saturated with a colored solution filled. The moving arc piece 912 is a high-temperature-resistant elastic sealing structure. When the semi-sealed ball rod 9 is in contact with the mouth part of the exhaust hole 401 and the inside of the inner liquid cylinder 42 is in a sealed state, after the bubbles in the glass liquid inside the inner liquid cylinder 42 gradually overflow, the gas in the empty space inside the inner liquid cylinder 42 will gradually increase. Due to the high temperature of the glass liquid, the gas will continuously expand. As Figure 10 , the moving arc piece 912 gradually deforms upward and pushes the colored solution to move upward to the part of the semi-sealed ball rod 9 outside the hole-aligning long cover 8. At this time, the staff can control the electric push rod 62 to work and at the same time make the suction pipe suck air outwards, effectively removing the overflowing air.

[0043] The part of the extension rod 92 located inside the hole-aligning long cover 8 is an elastic structure, so that when the middle moving bar 63 pulls the lower convex platform 43 to rotate continuously, the extension rod 92 can adaptively deform to a certain extent, making the semi-sealed ball rod 9 not easily affect the rotation of the inner liquid cylinder 42 with the lower convex platform 43. The part of the extension rod 92 located at the upper end of the hole-aligning long cover 8 is a rigid structure.

[0044] Compared with the first embodiment, the exhaust device connected to the suction pipe does not need to work continuously, which can effectively ensure the stability of the glass liquid and prevent the glass liquid from forming small particles that are dispersed into the air and escape outward due to continuous negative pressure adsorption.

[0045] In summary, when removing bubble, first stage is controlled earlier in that liquid cylinder 42 is constantly in the dynamic of swinging back and forth, its internal glass liquid is constantly concussed, be convenient to assist and accelerate part bubble to overflow, cooperate the effect of suction pipe simultaneously, can effectively outwards adsorb bubble, make above the glass liquid, form certain micro-negative pressure state, effectively guarantee the discharge of bubble, cooperate the setting of half-sealed ball rod 9 simultaneously, second stage, after each concussion, liquid cylinder 42 resets and is in sealed state in the control, now, part bubble overflows, due to the high temperature of glass liquid, gas can constantly expand, make the resistance ball bottom gradually upwards deformation, and push colored solution and make it move upwards to half-sealed ball rod 9 and be positioned at the part outside the long cover 8 of hole, now, liquid cylinder 42 is rotated again in staff's controllable interior, vent 401 is unsealed, make suction pipe outwards air-breathing simultaneously, effectively remove the air that overflows.

[0046] During specific implementation, those skilled in the art may select an appropriate implementation method according to actual needs.

[0047] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
