A mesh-belt crystallization furnace for preparing glass-ceramic plates using molten manganese alloy slag

Abstract

The present invention discloses a mesh-belt crystallization furnace for preparing microcrystalline glass plates by mixing molten manganese alloy slag. The mesh-belt crystallization furnace includes a roller kiln, a mesh belt, a release agent spraying device and a release agent drying device. The mesh belt is a continuous structure connected end to end and circulates around the roller kiln through a number of rollers. The release agent spraying device and the release agent drying device spray the release agent on the mesh belt and dry it. The arrangement of the mesh belt can effectively solve the problem that the softened glass liquid flows into the rollers and adheres to the rollers to cause the blocking rods, thereby significantly improving the continuity of the production process. The drying of the release agent is conducive to demoulding. On the other hand, by drying the release agent, the moisture content therein is reduced and the temperature of the release agent is increased to a certain extent, which can effectively prevent the temperature of the glass liquid from dropping on the side of the release agent due to the large temperature difference when the glass liquid contacts the release agent, thereby affecting the overall crystallization annealing uniformity of the glass liquid.

Description

Technical Field

[0001] The present invention relates to the technical field of industrial waste slag recycling equipment, in particular to a mesh belt type crystallization furnace for preparing microcrystalline glass plates by modulating molten manganese alloy slag. Background Art

[0002] The main components of manganese alloy slag are SiO2, Al2O3, CaO, MgO, MnO, etc., which have certain utilization value. Manganese alloy slag can be used in industry to manufacture microcrystalline glass plates. This method can not only recycle the effective components for reuse, but also reduce the stacking and treatment of solid waste, thereby reducing pollution to the environment. Therefore, it has good prospects.

[0003] The traditional production method of microcrystalline glass plates is mainly the water quenching sintering method. The commonly used crystallization sintering kilns are tunnel kilns and shuttle kilns. The crystallization process of the glass plates is the migration of solid-phase ions, and the deformation of the glass plates is relatively small. However, for microcrystalline glass plates directly prepared by mixing molten manganese alloy slag, the forming process is continuous and uninterrupted, so roller kilns are generally used for continuous production. When manganese alloy slag is used to prepare glass plates, it is a short-grain glass liquid, and the viscosity of the glass liquid changes greatly with temperature. When the traditional roller kiln is crystallized at high temperature, the glass liquid softens and flows due to the high crystallization temperature. The liquid flowing glass liquid will flow between the rods and adhere to the rollers, resulting in the phenomenon of sticking and blocking the rods. Therefore, it is necessary to design a special equipment that is suitable for the process of preparing microcrystalline glass plates with manganese alloy slag based on the process characteristics of manganese alloy slag. Summary of the Invention

[0004] In response to the above-mentioned problems, the technical purpose of the present invention is to provide a special equipment suitable for the process of preparing microcrystalline glass plates using manganese alloy slag, so as to overcome the various problems caused by traditional roller kilns when producing microcrystalline glass plates using manganese alloy slag as raw material.

[0005] The present invention is achieved through the following technical solutions:

[0006] A mesh-belt crystallization furnace for preparing microcrystalline glass plates by mixing molten manganese alloy slag comprises a roller kiln, a mesh belt, a release agent spraying device and a release agent drying device, wherein:

[0007] The roller kiln is provided with a forming channel for forming molten glass, wherein a plurality of rotatable rollers are provided in the forming channel, and the mesh belt is laid on the rollers and moves from the inlet side to the outlet side of the forming channel according to the rotation of the rollers;

[0008] The roller kiln is provided with a lower redirecting roller, a rotary channel and an upper steering roller. The lower redirecting roller is provided at the outlet side of the forming channel, and the upper redirecting roller is provided at the inlet side of the forming channel. The mesh belt is a continuous structure connected end to end. The mesh belt rotates continuously in the forming channel and the rotary channel under the action of the roller, the lower redirecting roller and the upper steering roller.

[0009] In the rotation direction of the mesh belt, the release agent spraying device is located on the upstream side of the release agent drying device; since the mesh belt is a continuous structure, the upstream side here refers to the positional relationship between the release agent spraying device and the release agent drying device with a shorter movement path.

[0010] The release agent spraying device is provided with a nozzle for spraying the release agent onto the side of the mesh belt contacting the glass liquid, and the release agent drying device is provided with a dryer for drying the release agent on the mesh belt.

[0011] The present invention provides a mesh-belt crystallization furnace for preparing microcrystalline glass plates by mixing molten manganese alloy slag. Compared with traditional roller kilns, the mesh-belt crystallization furnace of the present invention can effectively prevent the softened glass liquid from flowing into the rollers and sticking to the rollers to cause the blocking rods through the arrangement of the mesh belt, which can significantly improve the continuity of the production process and effectively match the uninterrupted production characteristics of microcrystalline glass plates prepared by manganese alloy slag. Therefore, it is particularly suitable as a special equipment for preparing microcrystalline glass plates with manganese alloy slag. In addition, before the mesh belt enters the forming channel, the glass liquid can be effectively prevented from sticking to the mesh belt during forming by spraying a release agent, which makes it difficult to separate. In addition, a release agent drying device is also specially provided. On the one hand, the drying of the release agent is conducive to demolding. On the other hand, the drying of the release agent reduces the moisture content therein and increases the temperature of the release agent to a certain extent. The beneficial effect is that it can effectively prevent the glass liquid from contacting the release agent side due to the large temperature difference, resulting in a temperature drop, affecting the overall crystallization annealing uniformity of the glass liquid, and thus causing the microcrystalline glass plate to have upper and lower stratification.

[0012] Furthermore, the release agent spraying device and the release agent drying device are located upstream of the mesh belt in the direction of rotation as it enters the forming channel. This arrangement further ensures the drying effect of the release agent and minimizes the temperature difference between the release agent and the molten glass when in contact, thereby more effectively preventing the undesirable phenomenon of stratification at the bottom of the molten glass, thereby improving the product quality of the microcrystalline glass sheet.

[0013] Furthermore, the rotary channel is equipped with return rollers that support the mesh belt as it moves within the rotary channel. This arrangement ensures smooth mesh belt movement. The speed of the mesh belt determines the forming time of the molten glass, thus improving the quality of the micro-ceramic glass sheet.

[0014] Furthermore, two upper redirecting rollers are provided and are spaced apart in the vertical direction, and two lower redirecting rollers are provided and are spaced apart in the vertical direction. The arrangement of two redirecting rollers facilitates the smooth movement of the mesh belt. Furthermore, the vertical spacing of the redirecting rollers can accommodate roller hearths of different heights. Specifically, the spacing depends on the height of the roller hearth, and more specifically, on the vertical spacing between the forming channel at the top and the rotary channel at the bottom of the roller hearth.

[0015] Furthermore, tensioning devices are provided on both sides of the forming channel for tensioning the mesh belt. This arrangement allows the mesh belt to be tensioned, which is beneficial for the flatness of the bottom surface of the glass forming process and the uniformity of its flow, thereby improving the quality of the glass-ceramic sheet.

[0016] Furthermore, the release agent spraying device includes a mud storage tank, a delivery pipe, a plunger pump, and a nozzle. The plunger pump delivers the release agent from the mud storage tank to the nozzle through the delivery pipe and controls the spray flow rate of the nozzle. By regulating the plunger pump, the spray flow rate of the nozzle can be controlled to meet the different release agent flow requirements under different production process conditions.

[0017] Furthermore, the release agent drying device is a combustion-type dryer that dries the release agent on the mesh belt by connecting to coal gas combustion. This release agent drying device is easy to set up, has low cost, and has a suitable drying effect, and is highly compatible with the crystallization furnace of the present invention.

[0018] Through the above arrangement, the present invention provides a mesh-belt crystallization furnace for preparing glass-ceramic plates by mixing molten manganese alloy slag, which has at least the following beneficial effects:

[0019] 1. Manganese alloy slag is mainly composed of SiO2, Al2O3, CaO, MgO, MnO, etc., which is short-grained glass liquid. The viscosity of the glass liquid changes greatly with temperature. When using a traditional roller kiln, due to the high crystallization temperature, the glass liquid softens and flows. The liquid glass liquid will flow between the rollers and stick to the rollers, resulting in the phenomenon of sticking and blocking the rollers. The design of the mesh belt roller kiln described in the present invention can effectively solve the above problem.

[0020] 2. The mesh-belt roller kiln of the present invention can be used to produce glass-ceramic sheets by tape casting, without the need for an edge stretcher. The forming speed and thickness are determined by the rotational speed of the rollers in the roller kiln. This makes the kiln easy to control and allows for continuous forming. It has high production efficiency and is particularly well-suited to the continuous production characteristics of the manganese alloy smelting industry.

[0021] 3. Through further optimization of the release agent spraying device, release agent drying device, tensioning device, etc., the problems of inconvenient demoulding and upper and lower stratification during glass liquid molding can be solved, which further plays a beneficial role in optimizing the process and improving product quality.

DETAILED DESCRIPTION

[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, left, and right" generally refer to the upper, lower, left, and right sides of the drawings; and "inner" and "outer" refer to the inner and outer sides relative to the outline of the component itself.

[0035] Example

[0036] like Figure 1 and Figure 2 As shown, this embodiment first provides a mesh-belt crystallization furnace for preparing microcrystalline glass plates by mixing molten manganese alloy slag, comprising a roller kiln 1, a mesh belt 2, a release agent spraying device 12 and a release agent drying device 3, wherein:

[0037] The roller kiln 1 is provided with a forming channel for forming glass liquid, and a plurality of rotatable rollers are provided in the forming channel. The mesh belt 2 is laid on the rollers and moves from the inlet side to the outlet side of the forming channel according to the rotation of the rollers. Figure 1 The forming channel is located at the upper part of the roller kiln 1, and a plurality of rollers are evenly laid on the bottom thereof. The rollers are actively rotated and drive the mesh belt 2 to move to one side. During the production process, there is molten glass on the mesh belt 2; the movement speed of the mesh belt 2 determines the forming time of the molten glass in the roller kiln 1. Therefore, the forming time of the molten glass can be flexibly controlled by controlling the rotation speed of the rollers.

[0038] The roller kiln is equipped with a lower redirecting roller, a rotary channel, and an upper steering roller. The lower redirecting roller is located at the exit side of the forming channel, and the upper redirecting roller is located at the entrance side of the forming channel. The mesh belt is a continuous structure connected end to end. Under the action of the rollers, the lower redirecting roller, and the upper steering roller, the mesh belt rotates continuously within the forming channel and the rotary channel. More specifically, there are two upper redirecting rollers, namely a first upper redirecting roller 4 and a second upper redirecting roller 5. The first upper redirecting roller 4 and the second upper redirecting roller 5 are arranged vertically in an upper and lower direction. The two lower redirecting rollers are provided with two lower redirecting rollers, namely a first lower redirecting roller 6 and a second lower redirecting roller 7. The first upper redirecting roller 4 and the first lower redirecting roller 6 are active redirecting rollers, while the second upper redirecting roller 5 and the second lower redirecting roller 7 are passive redirecting rollers.

[0039] The upper redirecting rollers and the lower redirecting rollers are respectively provided with two and are arranged at intervals in the upper and lower directions in the vertical direction. On the one hand, the arrangement of the two redirecting rollers is conducive to the smooth movement of the mesh belt. On the other hand, the vertical spacing of the redirecting rollers can adapt to the roller kilns 1 with different heights, that is, the size of the spacing depends on the height of the roller kiln 1. More specifically, the size of the spacing depends on the vertical spacing between the forming channel at the upper part of the roller kiln and the rotating channel at the lower part.

[0040] The release agent spraying device 12 is located upstream of the release agent drying device 3 in the direction of rotation. The release agent spraying device 12 includes a nozzle that sprays the release agent onto the surface of the mesh belt 2 that contacts the molten glass, while the release agent drying device 3 includes a dryer that dries the release agent on the mesh belt 2. Furthermore, the release agent spraying device 12 and the release agent drying device 3 are located upstream of the mesh belt 2 in the direction of rotation where it enters the forming channel. This arrangement further ensures the drying effect of the release agent and minimizes the temperature difference between the release agent and the molten glass when in contact, thereby more effectively preventing the undesirable phenomenon of stratification at the bottom of the molten glass, thereby improving the product quality of the microcrystalline glass sheet.

[0041] Combine Figure 2 The rotary channel is located at the bottom of the roller hearth kiln 1 and is equipped with return rollers 8 that support the mesh belt 2 as it moves within the rotary channel. This arrangement ensures smooth movement of the mesh belt 2. The speed of the mesh belt 2 determines the forming time of the molten glass, which helps improve the quality of the microcrystalline glass sheet.

[0042] The mesh belt 2 is a continuous structure connected end to end, and can be considered to encircle the roller hearth kiln 1. Tensioning devices are installed on both sides of the forming channel to tighten the mesh belt 2. This arrangement tightens the mesh belt 2, which promotes the flatness of the bottom surface of the molten glass forming process and the uniformity of its flow, thereby improving the quality of the glass-ceramic sheets.

[0043] In this embodiment, the release agent spraying device 12 includes a mud storage tank 10, a delivery pipe 11, a plunger pump 9 and a nozzle. The plunger pump 9 delivers the release agent from the mud storage tank 10 to the nozzle via the delivery pipe 11 and controls the spray flow rate of the nozzle. The spray flow rate of the nozzle is controlled by regulating the plunger pump 9 to match the different requirements for the release agent flow rate under different production process conditions. The mud storage tank 10, delivery pipe 11, plunger pump 9 and nozzle of the release agent spraying device 12 can be set separately from the roller kiln 1, which is more convenient to assemble on the one hand and easy to maintain and replace on the other hand.

[0044] The release agent drying device 3 is a combustion dryer, which dries the release agent on the mesh belt 2 by connecting to coal gas combustion. The release agent drying device 3 is easy to set up, has low cost, and has a suitable drying effect. It is highly compatible with the crystallization furnace described in this embodiment.

[0045] This embodiment provides a mesh-belt crystallization furnace for preparing glass-ceramics sheets using molten manganese alloy slag. Compared to conventional roller kilns, the mesh-belt crystallization furnace of this embodiment effectively prevents softened glass from flowing between rollers and sticking to them, resulting in blocking the rollers. This significantly improves the continuity of the production process and effectively matches the uninterrupted production characteristics of glass-ceramics sheets prepared using manganese alloy slag. Therefore, it is particularly suitable as a dedicated equipment for preparing glass-ceramics sheets using manganese alloy slag. Furthermore, before the mesh-belt 2 enters the forming channel, a release agent is sprayed on it to effectively prevent the glass from sticking to the mesh-belt 2 during forming and becoming difficult to remove. A release agent drying device is also provided. Drying the release agent not only facilitates demolding but also reduces its moisture content and increases its temperature to a certain extent. This beneficial effect is that it effectively prevents the glass from dropping in temperature on the side where it contacts the release agent due to a large temperature difference, which could affect the uniformity of the overall crystallization and annealing of the glass, and thus lead to the undesirable delamination of the glass-ceramics sheets.

[0046] like Figure 3 and Figure 4As shown, this embodiment further provides a high-temperature sidewall device for a glass-ceramic plate, comprising a sidewall structure 16, a power structure 14, a sidewall tensioning structure 13, and an adjustment structure 15. The sidewall structure 16 is a continuous flexible structure connected end to end, specifically a steel wire rope. The sidewall structure 16 is operatively connected to the power structure 14, the sidewall tensioning structure 13, and the adjustment structure 15, wherein:

[0047] The sidewall tightening structure 13 tightens the sidewall structure 16;

[0048] At least two adjustment structures 15 are provided and located on the same side of the roller kiln 1. The middle section of the sidewall structure 16 connecting the two adjustment structures 15 is a sidewall section 16a for preventing the glass liquid from spreading.

[0049] The power structure 14 drives the sidewall structure 16 to cyclically move among the power structure 14 , the sidewall tensioning structure 14 and the adjustment structure 15 .

[0050] More specifically, the sidewall structure 16 is a steel wire rope, which has certain flexibility, good high temperature resistance and wear resistance, and low cost.

[0051] The adjustment structure 15 is provided with a transverse distance adjustment structure 15b, which adjusts the connection point between the adjustment structure 15 and the sidewall structure 16 in the transverse distance of the roller hearth 1 in an adjustable manner. Through this arrangement, the distance between the sidewall segments 16a of the sidewall structure 16 on both sides of the roller hearth 1 can be controllably changed, that is, it can adapt to different widths of glass sheets. For example, by adjusting the transverse distance between the sidewall segments on both sides of the roller hearth 1, it can be changed from 1.2m to 1.25m, that is, the width of the formed glass sheet can be controlled from 1.2m to 1.25m. This arrangement can enhance the flexibility of the sidewall device.

[0052] In addition, the adjustment structure 15 is provided with an adjustment support. The adjustment structures 15 at corresponding positions on both sides of the roller kiln 1 share a common adjustment support. The adjustment support is provided with a guide rail. Under the action of the lateral adjustment structure 15b, the adjustment structure is configured to move laterally along the guide rail of the adjustment support or be fixed at a specific lateral position. This specific arrangement improves the flexibility of the sidewall device and further simplifies the structure.

[0053] The adjustment structure 15 is further provided with a driven bearing seat 15b, a driven shaft 15c, and a driven wheel 15d. The driven wheel 15d contacts the sidewall structure 16 and restricts the sidewall structure 16 from turning. The driven wheel 15d is connected to the driven bearing seat 15b via the driven shaft 15c. The driven bearing seat 15b is movable or fixed on the adjustment support via the lateral adjustment structure 15b.

[0054] The sidewall tensioning structure 13 includes two limiting wheels 13f, a tensioning wheel 13c, a tensioning frame 13a, a tensioning wheel support 13b, a tensioning counterweight 13d, a tensioning rope 13e and a limiting wheel support 13g.

[0055] The tensioning pulley 13c is located between the two limiting pulleys 13f. The sidewall structure 16 moves along the two limiting pulleys 13f and the tensioning pulley 13c. The position of the tensioning pulley 13c is variable, and the tension of the sidewall structure is increased or decreased by changing its position. The configuration of the limiting pulleys 13f and the tensioning pulley 13c is based on the purpose of allowing the tensioning pulley 13c to be variable and increase or decrease the tension of the sidewall structure by changing its position. Specifically, in this embodiment, the tensioning pulley 13c is suspended from the tensioning frame 13a via the tensioning pulley support 13b. The sidewall structure 16 is connected to the upper side of the tensioning pulley 13c and to the lower sides of the two limiting pulleys 13f. One end of the tensioning pulley support 13b is connected to the tensioning counterweight 13d via a tensioning rope 13e. By varying the weight of the tensioning counterweight 13d, the tension of the sidewall structure 16 can be quickly, conveniently, and flexibly controlled. It should be additionally explained that, in the present application, the meaning of connection includes not only physically fixed connection, but also non-fixed connection that can contact each other and produce physical effects.

[0056] In addition, the side guard tensioning structure 13 is arranged at the middle position between the two adjustment structures 15 along the length direction of the roller kiln 1. The side guard section 16a of the side guard structure 16 thus arranged has a more uniform tensioning effect.

[0057] The power structure 14 includes a power structure support 14a, a driving wheel 14b, a driving shaft 14c, a driving reversing wheel 14d, and a drive motor 14e. The power structure support 14a is connected to the side wall of the roller kiln 1 and supports other structures. The drive motor e drives the driving wheel 14b to rotate, and drives the driving reversing wheel 14d to rotate via the driving shaft 14c. The driving reversing wheel 14d contacts the sidewall structure 16, restricting the sidewall structure 16 from turning and providing a source of power for its movement.

[0058] For a single set of side guards, it is preferred that two power structures 14 be provided, with the two power structures 14 being located at the front and rear ends of the side guard section 16a along the length of the roller hearth kiln 1. This arrangement helps ensure the stability of the side guard structure's movement. In this embodiment, a single roller hearth kiln 1 is equipped with two sets of side guards, located on either side of the high-temperature crystallization section of the roller hearth kiln 1. Therefore, for a single roller hearth kiln 1, having four power structures 14 for the side guards is a preferred configuration.

[0059] In this embodiment, the adjustment structure 15 and the power structure 14 are fixedly connected to the roller kiln 1. In this way, the structural space occupied can be reduced, making the whole more compact.

[0060] This embodiment provides a high-temperature sidewall device for a microcrystalline glass plate, wherein the sidewall device is provided with a sidewall structure 16, a power structure 14, a sidewall tensioning structure 13, and an adjustment structure 15. The sidewall structure 16 is a continuous flexible structure connected end to end. The sidewall tensioning structure 13 is used to tighten the sidewall structure 16, and the sidewall structure 16 is in a tightened and taut state. Two adjustment structures 15 are provided, which are mainly used to cooperate with the sidewall structure 16 to form a stable sidewall segment 16a on one side of the high-temperature crystallization section of the roller kiln 1. The sidewall segment 16a directly contacts the high-temperature molten glass and prevents it from spreading. The other positions of the sidewall structure 16 do not directly contact the high-temperature molten glass. In addition, the power structure 14 drives the sidewall structure 16 to circulate between the power structure 14, the sidewall tensioning structure 13, and the adjustment structure 15, so that the sidewall structure 16 is continuously in a state of circulatory motion, so that the sidewall segment 16a in contact with the high-temperature molten glass is continuously in a changing state. For a certain position of the side guard structure 16, it is in a continuous cyclic motion process. When it acts as a side guard segment 16a to prevent the glass liquid from spreading, its temperature is high. Then it will move away from this position, thereby avoiding being in a high-temperature state for a long time. In this way, the problem of the side guard structure 16 being damaged due to being in a high-temperature state for a long time can be effectively solved, thereby significantly improving the reliability of the side guard device.

[0061] It should be noted that, due to space limitations, the present invention does not list all implementation plans. With reference to the above embodiments, it is easy for those skilled in the art to think of combining the technical features in different embodiments in a variety of ways, and the technical solutions obtained by such combinations obviously also belong to the technical content of the present invention. Similarly, modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, are also covered by the technical content recorded in the present invention.
