Technical Field
[0001] The utility model belongs to the technical field of reduction furnaces, and particularly relates to a reduction furnace sight glass with a guide ring. Background Art
[0002] The sight glass of the reduction furnace can be called the "window of the reduction furnace". It is one of the key components of the reduction furnace and can provide direct visual information about the operation of the furnace. However, during long-term operation, especially after 40 hours, substances such as silicone oil may be produced in the furnace. These substances will adhere to the sight glass, making it impossible to observe the situation in the furnace, which will have a serious impact on the operation and safety of the reduction furnace. In addition, fogging and discharge may occur during the operation of the reduction furnace, further increasing the challenge of keeping the sight glass clear.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
[0025] like Figure 1 and Figure 2 As shown, the reduction furnace sight glass with a guide ring of this embodiment includes a sight glass body 1, the sight glass body 1 is provided with a sight glass hole 11, a sight glass cover 2 is connected to the sight glass body 1, and a transparent sight glass sheet 3 is installed in the sight glass cover 2; a guide ring 4 for blocking silicon powder and silicone oil is installed in the sight glass hole 11 of the sight glass body 1.
[0026] A guide ring 4 is provided in the sight glass hole 11 of the utility model, and the guide ring 4 can effectively guide the gas flow entering the sight glass hole 11 from the reduction furnace, reduce the eddy current and dead zone generated by the gas in the sight glass hole 11, thereby effectively blocking the silicone oil and other substances carried by the gas from adhering to the transparent sight glass lens 3, ensuring that the sight glass can remain clear during normal operation.
[0027] The guide ring 4 of the utility model can effectively guide the flow, so that the "eyes" of the reduction furnace always remain clear. The unique design of the guide ring 4 prevents it from causing unnecessary interference to the gas flow in the furnace, ensuring that the gas flows freely in the furnace.
[0028] In the selection of materials, we fully considered the extreme environment such as high temperature and high pressure in the reduction furnace. The guide ring 4 device is made of stainless steel material, which has excellent corrosion resistance and can maintain stable structure and function in harsh environment.
[0029] In order to facilitate the disassembly and assembly of sulfur, three locking screws 41 with a diameter of 6 mm are threadedly connected on the guide ring 4, and one end of the locking screw 41 is pressed against the inner wall of the sight glass hole 11. When the locking screw 41 is pressed against the inner wall of the sight glass hole 11, the guide ring 4 is stably installed to ensure that the guide ring 4 guides the gas at a determined position. The outer diameter of the guide ring 4 is 80 mm, and the inner diameter of the guide ring 4 is 45 mm. The thickness of the guide ring 4 is 15 mm.
[0030] Furthermore, a plurality of air holes 12 for purging the transparent sight glass 3 are provided in the sight glass hole 11, and the air holes 12 are located on the side of the guide ring 4 close to the transparent sight glass 3. By introducing gas into the air holes 12 to purge and isolate the transparent sight glass 3, the gas entering from the reduction furnace is reduced from reaching the transparent sight glass 3, and silicone oil is further prevented from accumulating on the transparent sight glass 3. Hydrogen is introduced into the air holes 12. A plurality of air holes 12 are evenly distributed along the circumference of the sight glass hole 11. In the utility model, air holes 12 are provided in the entire radial circle of the sight glass hole 11, and the purge gas flow is evenly distributed on the transparent sight glass 3, so that the low-temperature hydrogen is protected by a reasonable layout to improve the purging effect on the transparent sight glass 3.
[0031] Furthermore, the transparent lens 3 is coated with an anti-fog coating or an anti-stick coating on one side facing the lens hole 11. An anti-fog coating or an anti-stick coating is added to the surface of the transparent lens 3 to reduce the effect of silicone oil adhesion and atomization on the transparent lens 3. At the same time, the durability and stability of the coating are tested and verified to ensure its effect and reliability during use.
[0032] The transparent lens 3 is made of high temperature glass or ceramic. The present invention uses high temperature resistant and anti-adhesion materials as the surface material of the transparent lens 3, such as high temperature glass, ceramic and other materials, to reduce the effect of silicone oil adhesion and atomization on the transparent lens 3.
[0033] Furthermore, a monitoring system is installed on the reduction furnace. The utility model introduces an advanced monitoring system and a safety system, which can promptly issue an alarm or take other safety measures when the viewing mirror cannot be observed normally, thereby ensuring the safe operation of the reduction furnace.
[0034] On the basis of adding the guide ring 4, it is also necessary to formulate a maintenance plan for regularly cleaning the transparent sight glass 3, and use appropriate cleaning agents and tools to remove silicone oil and other pollutants on the surface of the transparent sight glass 3 to ensure the clarity and observation effect of the transparent sight glass 3.
[0035] By adding the guide ring 4 and improving the design of the sight glass purge hole, the operation of the reduction furnace has been significantly improved:
[0036] First, the clarity of the transparent sight glass 3 has been greatly improved. After adding the guide ring 4, even if silicon powder is generated in the reduction furnace, the silicone oil cannot be blown along the viewing hole wall to the transparent sight glass 3, thereby effectively avoiding the problem of silicone oil accumulation on the transparent sight glass 3. This improvement allows the sight glass to remain clear during normal operation for up to 100 hours, and the operation of the furnace can be observed at any time. Previously, the transparent sight glass 3 would affect observation after 40 hours due to the adhesion of silicone oil. This improvement greatly improves the operator's ability to grasp the operation of the reduction furnace.
[0037] Second, after the technical transformation, the phase deficiency rate of the reduction furnace has been effectively reduced from the original 40% to 32.72%. This reduction in figures indicates that the efficiency of the reduction furnace has been improved during operation, and it also means that the waste in the production process has been reduced.
[0038] Third, through the improvement, the monthly average abnormal material ratio of the reduction furnace has also been significantly reduced. It has dropped from the original 6.5% to 5.57%. This reduction in the ratio can reduce the loss of abnormal materials by up to 75 tons per month. Calculated at 15,000 yuan per ton, the loss can be reduced by 1.125 million yuan per month. Not only has the economic loss been reduced, but the stability and reliability of the production process have also been enhanced.
[0039] In summary, the utility model improves and optimizes the design of the reduction furnace, not only improving its operating efficiency and safety, but also beautifying its operating process and results. These improvements not only bring economic benefits, but also enhance the operator's ability to master the operation of the reduction furnace.
[0040] The implementation method of the viewing mirror of the utility model comprises the following steps:
[0041] S1: Prepare materials: First, you need to prepare the material of the guide ring 4, and you can choose stainless steel, which is corrosion-resistant and wear-resistant. The material of the transparent lens 3 can also be selected from high temperature resistant, corrosion-resistant, and highly transparent materials, such as quartz glass, polycarbonate, etc.
[0042] S2: Designing the guide ring 4: According to the shape and size of the interior of the reduction furnace sight glass, the shape and size of the guide ring 4 are designed. The guide ring 4 can effectively guide the airflow and prevent silicon powder and silicone oil from adhering to the sight glass.
[0043] S3: Processing the guide ring 4: Use mechanical processing or CNC machine tools and other equipment to process the guide ring 4 into a designed shape and size. The guide ring 4 should have a smooth surface to prevent airflow from being obstructed.
[0044] S4: Install the guide ring 4: Install the processed guide ring 4 inside the reduction furnace sight glass to adapt to different air flow directions and speeds.
[0045] S5: Adjusting the guide ring 4: After the installation is completed, the guide ring 4 is debugged and adjusted to ensure that it can effectively guide the airflow and prevent the silicone powder and silicone oil from adhering to the transparent sight glass 3.
[0046] In all implementation processes, the guide ring 4 is an indispensable structure because it can effectively prevent silicon powder and silicone oil from adhering to the sight glass. The above is a most preferred solution. If other materials or other shapes of guide rings 4 are used, the utility model can also be implemented. For example, other metal materials can be used instead of stainless steel, and other shapes of guide rings 4 can also be designed to adapt to different internal shapes and sizes of reduction furnaces.
[0047] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
