Description

Technical Field

[0001] This utility model relates to the field of fused silica preparation technology, and in particular to a high-temperature sintering furnace for preparing high-purity fused silica. Background Technology

[0002] High-purity fused silica refers to high-purity silicon dioxide (SiO2) material produced through melting and cooling processes. Its purity can usually reach over 99.99%. This material has very low impurity content and excellent optical properties. A high-temperature sintering furnace is a device specifically used for high-temperature processing and sintering of materials. It can heat powdered or granular raw materials to their melting point or near their melting point in a high-temperature environment to achieve melting and bonding of the materials.

[0003] In the existing technology, quartz raw materials are placed in a reaction tank and then melted in a high-temperature sintering furnace. However, the lack of a stirring mechanism in the reaction tank results in some quartz raw materials not melting, which reduces the quality of high-purity fused quartz produced by the high-temperature sintering furnace. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some quartz raw materials do not melt when using existing equipment because the reaction tank in the high-temperature sintering furnace lacks a stirring mechanism. Therefore, this invention proposes a high-temperature sintering furnace for preparing high-purity fused quartz.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature sintering furnace for preparing high-purity fused silica, comprising an operation panel, a sintering furnace body fixedly mounted on the top of the operation panel, a horizontal plate fixedly mounted on the inner wall of the sintering furnace body, a heater fixedly mounted on the bottom of the inner wall of the sintering furnace body, a reaction tank fixedly mounted on the top of the horizontal plate, two drive motors fixedly mounted on one side of the outer wall of the reaction tank, drive rods fixedly mounted on one side of the outer wall of each of the two drive motors, multiple stirring plates fixedly mounted on the outer walls of each of the two drive rods, a temperature sensor fixedly mounted on one side of the inner wall of the reaction tank, and a controller fixedly mounted on one side of the outer wall of the sintering furnace body.

[0006] Preferably, two gas monitoring instruments are fixedly installed on the inner wall of the sintering furnace body, and four pressure relief pipes are fixedly inserted into the outer wall of the sintering furnace body.

[0007] Preferably, a pressure relief valve is fixedly installed on the outer wall of each of the four pressure relief pipes, and two blowers are fixedly installed on the top of the control panel.

[0008] Preferably, air ducts are fixedly installed on the top of both blowers, and the output ends of both air ducts are connected to the interior of the sintering furnace body. A cold water tank is fixedly installed on the top of the control panel.

[0009] Preferably, a cover plate is fixedly installed on the top of the cold water tank, and a cooling water pipe is fixedly inserted into the top of the cover plate, with the outer wall of the cooling water pipe connected to the interior of the sintering furnace body.

[0010] Preferably, a water pump is fixedly installed on the outer wall of the cooling water pipe, a transition box is fixedly installed on the top of the control panel, and the output end of the cooling water pipe is connected to the interior of the transition box.

[0011] Preferably, a water inlet pipe is fixedly inserted into one side of the outer wall of the cold water tank, and a connecting pipe is fixedly inserted into one side of the outer wall of the transition tank.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the heater is started by the controller, and in conjunction with the temperature sensor, the temperature inside the sintering furnace is raised to a suitable range to melt the raw material quartz. At the same time, the controller starts two drive motors, which drive two drive rods and multiple stirring plates to stir the raw material quartz in the reaction tank. This helps to improve the uniformity of the raw material and the heat transfer efficiency, ensuring that all raw materials can be heated evenly and melted at the appropriate temperature, thereby improving the quality of high-purity fused quartz produced by this high-temperature sintering furnace.

[0014] In this invention, two gas monitors are used to monitor the concentration of inert gas inside the furnace. When the concentration is outside the set range, two blowers are used to introduce inert gas into the furnace through two air ducts. At the same time, four pressure relief valves are opened to release the gas inside the furnace, ensuring stable gas pressure. Secondly, when the temperature inside the sintering furnace is higher than the set value, the water pump is turned on, allowing water from the cold water tank to flow through the cooling water pipes and through the interior of the sintering furnace, carrying away some of the heat until the temperature returns to the original set value. This ensures the quality of high-purity fused silica produced by the high-temperature sintering furnace. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a high-temperature sintering furnace for preparing high-purity fused silica, including an operation plate 1, a sintering furnace body 2 fixedly mounted on the top of the operation plate 1, a horizontal plate 3 fixedly mounted on the inner wall of the sintering furnace body 2, a heater 4 fixedly mounted on the bottom of the inner wall of the sintering furnace body 2, a reaction tank 5 fixedly mounted on the top of the horizontal plate 3, two drive motors 6 fixedly mounted on one side of the outer wall of the reaction tank 5, drive rods 7 fixedly mounted on one side of the outer wall of each of the two drive motors 6, and multiple stirring plates 8 fixedly mounted on the outer walls of each of the two drive rods 7. A temperature sensor 9 is fixedly installed on one side of the inner wall of the reaction tank 5. A controller 10 is fixedly installed on one side of the outer wall of the sintering furnace body 2. Two gas monitors 11 are fixedly installed on the inner surface of the sintering furnace body 2. Four pressure relief pipes 12 are fixedly inserted into the outer surface of the sintering furnace body 2. Pressure relief valves 13 are fixedly installed on the outer surface of each of the four pressure relief pipes 12. Two blowers 14 are fixedly installed on the top of the control panel 1. Air ducts 15 are fixedly installed on the top of each of the two blowers 14, and the output ends of the two air ducts 15 are connected to the interior of the sintering furnace body 2.

[0024] The overall effect of Embodiment 1 is as follows: raw quartz is placed in the reaction tank 5 and fixed on the horizontal plate 3 above the heater 4. The controller 10 is electrically connected to the heater 4, drive motor 6, four pressure relief valves 13, two blowers 14, and water pump 19. The controller 10 starts the heater 4 to heat the quartz raw material in the reaction tank 5 at a high temperature. In conjunction with the temperature sensor 9, the temperature inside the sintering furnace body 2 can be raised to a suitable range. At the same time, the controller 10 starts the two drive motors 6 installed on one side of the reaction tank 5, which drive the two drive rods 7 and multiple stirring plates 8 to stir the quartz raw material in the reaction tank 5, thereby improving the uniformity of the quartz raw material and heat transfer. The high-temperature sintering furnace ensures efficient heating and uniform melting of all raw materials at appropriate temperatures. Two gas monitors 11 monitor the atmosphere composition within the furnace body 2 in real time. When the concentration of inert gases such as argon is outside the set range, the controller 10 activates two blowers 14 and opens four pressure relief valves 13. This allows the inert gases connected to the blowers 14 to enter the furnace body 2 through two ducts 15. Simultaneously, the gases within the furnace body 2 are discharged through the four pressure relief pipes 12. This not only ensures that the concentration of inert gases such as argon is within the set range but also maintains the gas pressure within the furnace body 2, thereby improving the quality of high-purity fused silica produced by the furnace.

[0025] Example 2: As Figures 2-4 As shown, a cold water tank 16 is fixedly installed on the top of the control panel 1, a cover plate 17 is fixedly installed on the top of the cold water tank 16, a cooling water pipe 18 is fixedly inserted on the top of the cover plate 17, and the outer wall of the cooling water pipe 18 is connected to the interior of the sintering furnace body 2. A water pump 19 is fixedly installed on the outer wall of the cooling water pipe 18. A transition box 20 is fixedly installed on the top of the control panel 1, and the output end of the cooling water pipe 18 is connected to the interior of the transition box 20. A water supply pipe 21 is fixedly inserted on one side of the outer wall of the cold water tank 16, and a connecting pipe 22 is fixedly inserted on one side of the outer wall of the transition box 20.

[0026] The effect achieved by the entire embodiment 2 is that when the temperature inside the sintering furnace body 2 is higher than the original set temperature, the water pump 19 is turned on by the controller 10, so that the cold water in the cold water tank 16 flows along the cooling water pipe 18. The water supply pipe 21 is connected to an external water source to ensure that there is enough cold water. Then, it passes through the interior of the sintering furnace body 2 and takes away some heat. Then it returns to the transition box 20 and can be used for other processes through the connecting pipe 22, ensuring the recovery and utilization of heat energy until the temperature inside the sintering furnace body 2 returns to the original set value, thus ensuring the quality of high-purity fused silica prepared by the high-temperature sintering furnace.

[0027] Working principle: First, when the quartz raw material is placed in the reaction tank 5 and inside the sintering furnace body 2, the heater 4 is started by the controller 10. Under the action of the temperature sensor 9, the temperature inside the sintering furnace body 2 can be raised to the temperature required for melting quartz. When the temperature sensor 9 detects that the internal temperature is too high, the water pump 19 is turned on by the controller 10, so that the cold water in the cold water tank 16 flows along the cooling water pipe 18, carrying away some of the heat inside the sintering furnace body 2. Then, the water returns to the transition tank 20 and is used for other processes. Next, the two drive motors 6 are started by the controller 10, which drive the two drive rods 7 and multiple stirring plates 8 to stir the quartz raw material, thereby improving the uniformity and heat transfer efficiency of the quartz raw material. To ensure that the quartz raw material is heated evenly and melted at an appropriate temperature, two gas monitors 11 are activated. When the concentration of inert gases such as argon in the sintering furnace body 2 is outside the set range, the controller 10 starts two blowers 14, allowing the inert gases connected to the two blowers 14 to enter the sintering furnace body 2 through the two air ducts 15. At the same time, the controller 10 opens the pressure relief valves 13 installed on the four pressure relief pipes 12, allowing the gas in the sintering furnace body 2 to be discharged through the four pressure relief pipes 12. This not only ensures that the concentration of inert gases such as argon in the sintering furnace body 2 is within the set range, but also ensures the gas pressure in the sintering furnace body 2, thereby improving the quality of high-purity fused quartz produced by the high-temperature sintering furnace.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
