Description

Technical Field

[0001] The utility model relates to the technical field of flat glass testing, and particularly relates to a physical simulation system of a glass melting furnace with a thermal power composite melting simulation system. Background Art

[0002] Flat glass is a high energy-consuming and high-emission industry, and fuel accounts for about 35% of the total cost of glass production. In order to achieve energy conservation and carbon reduction, the use of thermal power composite melting technology can significantly reduce the energy consumption of glass melting, and can increase the glass production capacity under specific conditions. The thermal power composite melting technology is still in the experimental exploration stage in the field of flat glass. If a physical melting furnace is used to study the thermal power composite melting system, the investment cost is too high and energy waste will be caused.

[0003] Physical simulation uses the similarity principle. In a small-scale model similar to the prototype of the melting furnace, a simulation liquid similar to the properties of high-temperature glass liquid is used to establish a physical simulation device to explore the influence of different schemes on the operating state of the melting furnace.

[0004] In view of this situation, there is currently a physical simulation device for glass liquid flow on the market, such as the Chinese patent with the publication number CN204434457U. The physical simulation device for glass liquid flow includes a feeding tank, a main liquid tank and a liquid storage tank. The main liquid tank includes a melting part, a necking part, a cooling part and a flow channel. The melting part is provided with an infrared thermal radiation heating device. The simulation liquid enters the main liquid tank from the feeding tank, and sequentially passes through the melting part, the necking part, the cooling part and the flow channel to enter the liquid storage tank, realizing the simulation of the glass liquid flow. By changing the parameters of different links to carry out process optimization experiments, the influence of process parameters on the glass liquid flow is intuitively studied, providing a reference basis for production practice.

[0005] Although the physical simulation device for glass liquid flow has many advantages as above, in the actual use process, the inventor found that its heating device still has deficiencies. Specifically, the heating device can only simulate single flame heating, which has certain limitations. In the actual production process, in order to save energy and reduce emissions, more exploration of the combination of flame heating and auxiliary electric heating is needed to achieve the purpose of reducing the energy consumption of glass melting and increasing the glass production capacity.

[0006] Therefore, based on the above deficiencies, there is an urgent need to design a physical simulation system of a glass melting furnace with a thermal power composite melting simulation system, which is used to simulate the matching relationship between auxiliary electric heating and flame heating, guide and optimize the determination of the thermal power composite melting scheme, and provide a reference basis for production practice. Content of the Utility Model

[0007] In order to solve the deficiencies of the prior art, the utility model provides a physical simulation system of a glass melting furnace with a thermal power composite melting simulation system.

[0008] It adopts the following technical solution:

[0009] A physical simulation system of a glass melting furnace with a thermal power composite melting simulation system, including a simulation pool for containing simulation liquid. The simulation pool successively includes a feeding port, a melting pool, a necking, a cooling pool and a liquid storage pool. A thermal radiation device for simulating flame heating is arranged on the upper side of the melting pool. An electric heating device for simulating electric heating is arranged on the bottom plate of the melting pool. The electric heating device includes a group of electrodes evenly distributed, and the magnitude of the current passing through each electrode can be independently adjusted.

[0010] Furthermore, through holes corresponding to and sliding-sealedly matched with each electrode are arranged on the bottom plate; each electrode is respectively connected with a telescopic adjusting device;

[0011] The telescopic adjusting device includes a sleeve fixedly connected to the bottom plate at the upper end. The electrode is slidably matched in the sleeve. The lower part of the electrode has a flange. A spring with elastic limit is arranged between the flange and the upper end of the sleeve. A threaded through hole is arranged at the lower end of the sleeve. The threaded through hole is connected with an adjusting bolt. The end of the stud of the adjusting bolt extends into the sleeve and presses against the bottom end of the electrode. By rotating the adjusting bolt, the length of the electrode extending into the melting pool can be changed.

[0012] Furthermore, the thermal radiation device includes a cover plate. A group of evenly distributed infrared thermal radiation lamps are arranged on the lower surface of the cover plate, and the brightness of each infrared thermal radiation lamp can be independently adjusted.

[0013] Furthermore, a group of evenly distributed measuring components are also arranged on the cover plate. Each measuring component includes a temperature probe for measuring the temperature in the simulation pool and a potential probe for measuring the potential in the simulation pool.

[0014] Furthermore, the measuring component also includes a guide sleeve. The temperature probe and the potential probe are fixedly connected in the guide sleeve. A guide hole slidably matched with the guide sleeve is arranged on the cover plate, and the guide sleeve can move up and down along the guide hole.

[0015] Furthermore, a convex platform for forming a limit with the upper surface of the cover plate is arranged on the guide sleeve.

[0016] Furthermore, the liquid storage pool is communicated with the feeding port through a conduit. A peristaltic pump is arranged on the conduit, and the peristaltic pump makes the simulation liquid in the liquid storage pool flow into the feeding port through the conduit.

[0017] Furthermore, hollow interlayers for reducing heat exchange are arranged on both the pool wall and the pool bottom of the simulation pool.

[0018] The beneficial effects of the utility model compared with the prior art:

[0019] In the solution of this application, the simulation pool successively includes a feeding port, a melting pool, a necking section, a cooling pool and a liquid storage pool. The simulation pool realistically reflects the structure of the glass melting furnace. The thermal radiation device and the electric heating device respectively simulate flame heating and electric heating. By adjusting the parameters of the thermal radiation device and the electric heating device, the matching relationship between the simulated auxiliary electric heating and the flame heating is realized, guiding and optimizing the determination of the thermal-electric composite melting plan, and providing a reference basis for production practice;

[0020] The setting of the cover plate facilitates the laying of infrared radiation lamps on the one hand, enabling a more uniform arrangement of a number of infrared radiation lamps above the melting area, achieving a better heating effect, making the simulated flame heating closer to the actual flame heating, and improving the authenticity of the simulation effect. On the other hand, it has a heat insulation effect, reducing the exchange between the thermal radiation device and the outside cold air, enabling more of the heat energy provided by the thermal radiation device to be transferred to the simulated liquid, which is beneficial to the heating control of the simulated liquid; In addition, the brightness of a single infrared thermal radiation lamp can be independently adjusted, so that the amount of heat energy provided by a single infrared thermal radiation lamp is different, facilitating the heating control of different areas of the simulated liquid;

[0021] By setting the electric heating device to electrically heat the simulated liquid, the electric heating device is set as a number of electrodes, and the number of electrodes are evenly laid on the bottom plate so that the electrodes heat the simulated liquid more evenly, achieving a better heating effect; The magnitude of the current passing through a single electrode can be independently adjusted to control the amount of electrical energy provided by the electrode, facilitating the electric heating control of different areas of the simulated liquid;

[0022] The setting of the telescopic adjustment device enables the electrodes to extend above the bottom plate or retract into the bottom plate. When electric heating is required in some areas, the telescopic adjustment device is adjusted to make the electrodes in the areas where electric heating is required extend above the bottom plate. When electric heating is not required in some areas, the telescopic adjustment device is adjusted to make the electrodes in the areas where electric heating is not required retract into the bottom plate. In this way, independent heating of the areas where electric heating is required is achieved, and at the same time, the influence of the electrodes in the areas where electric heating is not required on the flow of the simulated liquid is reduced, improving the authenticity of the simulation effect and being beneficial to the simulation of the thermal-electric composite melting;

[0023] The setting of the hollow layer separates the simulation pool from the external environment. During the heating process of the simulated liquid, the heat loss in the simulation pool is reduced, making the simulation pool closer to the real glass melting furnace, improving the authenticity of the simulation effect, and being beneficial to the simulation of the thermal-electric composite melting.

Detailed implementation manners

[0031] To make the present invention more clearly understood, the following further describes a physical simulation system of a glass melting furnace with a thermal power composite melting simulation system according to the present invention with reference to the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] As Figures 1 to 3 shown, a physical simulation system of a glass melting furnace with a thermal power composite melting simulation system includes a simulation pool 1 for containing simulation liquid. The simulation pool 1 is sequentially divided into a feeding port 11, a melting pool 12, a throat 13, a cooling pool 14 and a liquid storage pool 15 from left to right. The liquid storage pool 15 is communicated with the feeding port 11 through a conduit 16. A peristaltic pump 17 is arranged on the conduit 16. The peristaltic pump 17 makes the simulation liquid in the liquid storage pool 15 flow into the feeding port 11 through the conduit 16, so that the simulation liquid can be recycled, saving resources and increasing the continuity of the simulation at the same time.

[0033] A thermal radiation device 2 for simulating flame heating is provided above the melting pool 12, and an electric heating device 3 for simulating actual electric heating is provided on the bottom plate 121 of the melting pool 12. By adjusting the parameters of the thermal radiation device 2 and the electric heating device 3, the matching relationship between the simulated auxiliary electric heating and the flame heating is realized, guiding and optimizing the determination of the thermal power composite melting scheme, and providing a reference basis for production practice.

[0034] In order to reduce the heat loss in the simulation pool 1 during the heating of the simulation liquid and make the simulation pool 1 closer to the real glass melting furnace, a hollow interlayer 1a for reducing heat exchange is provided on both the pool wall and the pool bottom of the simulation pool 1.

[0035] The electric heating device 3 includes a group of electrodes 31 evenly distributed, and each electrode 31 is respectively connected to a regulator (not shown in the figure) that can control the magnitude of the current, so that the magnitude of the current passing through each electrode 31 can be independently adjusted.

[0036] Preferably, the electrode 31 has an up and down telescopic function. The electrode 31 can extend into the melting pool 12 to independently heat the simulation liquid in the melting pool 12, and can also retract the electrode 31 into the bottom plate 121 of the melting pool 12 according to needs, reducing the influence on the flow of the simulation liquid, improving the authenticity of the simulation effect, and being beneficial to the simulation of the thermal power composite melting. The structure for realizing the above functions is as Figure 3 、 Figure 5As shown in the figure, through holes 122 which are in sliding and sealing fit with each electrode 31 are provided on the bottom plate 121. The electrode 31 and the through hole 122 are adapted in cross-sectional shape, both being circular. Its sealing structure is realized, for example, by a high-temperature resistant sealing ring 33 provided in the hole wall groove of the through hole 122 to achieve sealing fit with the peripheral surface of the electrode 31. A telescopic adjusting device 32 is connected to the lower part of each electrode 31 respectively. The telescopic adjusting device 32 includes a sleeve 321. The upper end of the sleeve 321 passes through the hollow interlayer 1a and is fixedly connected to the bottom plate 121, and the sleeve 321 is coaxially communicated with the corresponding through hole 122. The inner hole size of the sleeve 321 is larger than the size of the through hole 122. The lower end of the electrode 31 passes through the through hole 122 and is in sliding fit in the sleeve 321. Among them, a flange 311 which has a clearance fit with the inner wall of the sleeve 321 is provided at the lower part of the electrode 31. A spring 322 is provided between the upper end surface of the flange 311 and the upper end of the sleeve 321. The spring 322 is sleeved on the rod body of the electrode 31 with a clearance, and is elastically in contact with the upper surface of the flange 311 at one end and in contact with the limiting surface where the upper end of the sleeve 321 is located at the other end. A threaded through hole 323 is provided at the lower end of the sleeve 321. The axis of the threaded through hole 323 coincides with the axis of the sleeve 321. An adjusting bolt 324 is connected to the threaded through hole 323. The stud end of the adjusting bolt 324 extends into the sleeve 321 and presses against the bottom end of the electrode 31. By screwing in the adjusting bolt 324, the electrode 31 can be pressed to extend into the melting pool 12. By screwing out the adjusting bolt 324, under the elastic action of the spring 322, the electrode 31 can be retracted from the melting pool 12.

[0037] Combined Figure 3 、 Figure 4 、 Figure 6 As shown in the figure, the thermal radiation device 2 includes a cover plate 21. The cover plate 21 is clamped on the top surface of the simulation pool 1. The cover plate 21 has downward edges around it, making its opening face downward. A group of evenly distributed infrared thermal radiation lamps 22 are provided on the lower surface of the cover plate 21. The brightness of each infrared thermal radiation lamp 22 can be independently adjusted. A group of evenly distributed measuring components 23 are also provided on the cover plate 21. Each measuring component 23 includes a temperature probe 231 for measuring the temperature in the simulation pool and a potential probe 232 for measuring the potential in the simulation pool. The temperature probe 231 and the potential probe 232 are both vertically arranged.

[0038] In some embodiments, the measurement assembly 23 further includes a guide sleeve 233. The temperature probe 231 and the potential probe 232 are both fixedly connected within the guide sleeve 233. Correspondingly, a guide hole 24 corresponding to the guide sleeve 233 is provided on the cover plate 21. The guide sleeve 233 and the guide hole 24 form a guiding fit, and the guide sleeve 233 together with the temperature probe 231 and the potential probe 232 move up and down along the guide hole 24, so as to measure the temperature and potential distribution in different regions of the simulation pool 1, and correspondingly adjust the thermal radiation device 2 or the electric heating device 3 in different regions, making the distribution of temperature and potential more reasonable, which is beneficial to the simulation of thermal-electric composite melting.

[0039] In addition, in order to prevent the guide sleeve 233 from falling out of the guide hole 24, a boss 234 is provided on the upper part of the guide sleeve 233 to form a limit with the upper surface of the cover plate 21.

[0040] In some embodiments, the simulation pool 1 is transparent. For example, it can be made of a transparent acrylic plate (plexiglass). The transparent simulation pool 1 is convenient for observing the flow of the simulation liquid. At the same time, a tracer can be added to the simulation liquid, and the tracer flows along with the flow of the simulation liquid, making it easier to observe the specific flow of the simulation liquid.

[0041] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the embodiments here. And these obvious changes or variations derived from the essence of the present invention still fall within the protection scope of the present invention.
