Technical Field

[0001] This utility model relates to the field of slag preparation technology, specifically to an efficient preparation device for high-fluorine synthetic slag. Background Technology

[0002] In the steelmaking process, slag formation is a crucial step. Good slag performance is of great significance for removing impurities from steel, controlling the temperature of molten steel, and protecting the furnace lining. With the continuous development of the steel industry, higher requirements have been put forward for steel quality and production efficiency. The high-fluorine synthetic slag material high-efficiency preparation device has emerged in response to the comprehensive background of the development needs of the steel industry, the problems of traditional preparation technology, and related technological progress.

[0003] However, existing high-efficiency preparation devices for high-fluorine synthesis slag still have some problems in use:

[0004] First, in existing preparation devices, due to unreasonable design of the stirring blades or uneven stirring speed, various raw materials cannot be fully and evenly mixed, which affects the stability and performance of the slag material and thus affects the effect of the preparation device in preparing slag material.

[0005] Secondly, the preparation of high-fluorine synthetic slag will generate waste gas containing harmful gases such as fluorine. The existing preparation equipment lacks a structure for waste gas treatment, and the waste gas is discharged directly without treatment, causing environmental pollution and reducing the practicality of the preparation equipment. Utility Model Content

[0006] In order to solve the problems of existing preparation devices being unable to fully and uniformly mix raw materials and the environmental pollution caused by waste gas generated during the preparation process, the purpose of this utility model is to provide an efficient preparation device for high-fluorine synthesis slag.

[0008] Preferably, the waste gas adsorption assembly includes multiple support plates, and the corresponding support plates are symmetrically fixedly installed in the inner cavity of the exhaust pipe.

[0010] 1.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides an efficient preparation device for high-fluorine synthesis slag, including a reactor body 1. The upper surface of the reactor body 1 is connected to a feed pipe 5, which facilitates the addition of raw materials into the reactor body 1. A sealing cover 4 is hinged to one side of the upper surface of the feed pipe 5. When no material is being fed, the sealing cover 4 can be closed to prevent gas leakage from the reactor body 1. The lower surface of the reactor body 1 is connected to a discharge pipe 6, which is used to discharge the prepared slag. The outer surface of the discharge pipe 6 is provided with a control valve 7, which can control the discharge speed and discharge volume of the slag, facilitating operation according to production needs.

[0019] The upper surface of the reactor body 1 is connected to an exhaust pipe 8, which provides a channel for the exhaust gas generated during the reaction process, ensuring stable gas pressure inside the reactor body 1 and preventing the accumulation of exhaust gas from affecting the reaction. A rectangular array of support rods 9 are fixedly connected to the upper surface of the exhaust pipe 8, providing support. A conical wind cap 10 is fixedly connected to the upper surface of the support rods 9, which utilizes wind pressure to improve exhaust efficiency while preventing rainwater and debris from entering the exhaust pipe 8. An exhaust gas adsorption component 3 is installed inside the exhaust pipe 8, effectively removing harmful substances from the exhaust gas, such as fluorine-containing gases, thus preventing environmental pollution and achieving compliant emissions. A linkage stirring mechanism 2 is installed inside the reactor body 1, enhancing the stirring effect of the raw materials, ensuring thorough mixing, improving the stability and performance of the slag material, and achieving efficient preparation of the slag material.

[0020] The linkage stirring mechanism 2 includes a support shell 22, which is fixedly installed on the upper surface of the reactor body 1. An AC asynchronous motor 21 is fixedly installed on the upper surface of the support shell 22. The support shell 22 protects and supports the AC asynchronous motor 21. The output end of the AC asynchronous motor 21 passes through the support shell 22 and is fixedly connected to a drive gear 26, so that the output end of the AC asynchronous motor 21 can drive the drive gear 26 to rotate. Multiple driven gears 23 are meshed on the outer surface of the drive gear 26. The multiple driven gears 23 are arranged in a ring array. The number of teeth of the driven gears 23 and the drive gear 26 are the same, so that the rotation of the drive gear 26 can drive the multiple driven gears 23 to rotate synchronously.

[0021] Furthermore, a vertical rod 25 is fixedly connected to the lower surface of the driven gear 23, which facilitates the rotation of the driven gear 23 to drive the vertical rod 25 to rotate. The bottom end of the vertical rod 25 passes through the reactor body 1 and is rotatably connected to the inner cavity of the reactor body 1. Stirring blades 24 are fixedly sleeved at equal intervals on the outer surface of the vertical rod 25. The rotation of the vertical rod 25 drives multiple stirring blades 24 to rotate synchronously, realizing multi-directional stirring, improving the uniformity and intensity of stirring, ensuring thorough mixing of raw materials, improving the compositional stability and performance of the slag material, and achieving efficient preparation of the slag material.

[0022] The vertical rod 25 is made of stainless steel, which ensures the strength and corrosion resistance of the vertical rod 25. The stirring blade 24 is made of stainless steel, which is wear-resistant and corrosion-resistant. The inner cavity of the reactor body 1 is made of stainless steel, which can prevent the reactor body 1 from being corroded in complex chemical environments such as high fluorine, extend the service life of the reactor, and ensure the safety and stability of the reaction process.

[0023] The exhaust gas adsorption component 3 includes multiple support plates 35, which are symmetrically fixedly installed in the inner cavity of the exhaust pipe 8 to provide support for silica gel 34, activated alumina 33, molecular sieve 32 and activated carbon fiber 31.

[0024] Correspondingly, the upper surface of the support plate 35 is movably provided with silica gel 34, activated alumina 33, molecular sieve 32, and activated carbon fiber 31. Silica gel 34 preferentially adsorbs moisture in the exhaust gas, reducing the humidity of the exhaust gas. Activated alumina 33 further dries the exhaust gas, removing some acidic or alkaline gases and pollutants such as fluorides. Molecular sieve 32 selectively adsorbs specific pollutants in the exhaust gas according to the size and shape of the molecules. Activated carbon fiber 31 finely adsorbs various organic pollutants and some inorganic pollutants, ensuring that the exhaust gas treated by the above adsorption materials reaches a higher purification standard and achieves compliant emission. The silica gel 34, activated alumina 33, molecular sieve 32, and activated carbon fiber 31 all have damping movement through one side of the exhaust pipe 8, which facilitates replacement after the adsorption material is saturated, ensuring that the exhaust gas adsorption component 3 continues to work effectively.

[0025] Working principle: First, open the hinged sealing cover 4 on the feed pipe 5, and add the various raw materials required for preparing high-fluorine synthesis slag into the reactor body 1 through the feed pipe 5. After the addition is completed, close the sealing cover 4.

[0026] Then, the AC asynchronous motor 21 in the linkage stirring mechanism 2 is started. The output end of the AC asynchronous motor 21 drives the drive gear 26 to rotate. The rotation of the drive gear 26 drives the driven gear 23 to rotate synchronously. The rotation of the driven gear 23 drives the vertical rod 25 to rotate accordingly.

[0027] The vertical rod 25 rotates, driving the stirring blades 24 to rotate and stir the raw materials in the reactor body 1. Multiple stirring blades 24 work at different levels and in different directions, so that the raw materials are fully mixed, ensuring the stability and performance of the slag material composition and achieving efficient preparation.

[0028] Under stirring, the raw materials react in the reactor body 1 to generate high-fluorine synthesis slag.

[0029] Waste gas containing harmful gases such as fluorine generated during the reaction is discharged through the exhaust pipe 8 connected to the upper surface of the reactor body 1. The conical wind cap 10 uses wind pressure to improve exhaust efficiency and prevents rainwater, debris and other substances from entering the exhaust pipe 8.

[0030] During the exhaust process, the exhaust gas adsorption component 3 plays a role, passing through silica gel 34, activated alumina 33, molecular sieve 32, and activated carbon fiber 31 in sequence. Silica gel 34 first adsorbs the moisture in the exhaust gas to reduce the humidity. Activated alumina 33 further dries the exhaust gas and removes some acidic or alkaline gases as well as pollutants such as fluorides. Molecular sieve 32 selectively adsorbs specific pollutants in the exhaust gas, and activated carbon fiber 31 performs fine adsorption on various pollutants. Through a series of adsorption processes, the exhaust gas is ensured to meet emission standards.

[0031] Meanwhile, since silica gel 34, activated alumina 33, molecular sieve 32 and activated carbon fiber 31 all have damping activity through one side of the exhaust pipe 8, it is convenient to replace the adsorption material after it becomes saturated, ensuring that the waste gas treatment is continuously effective.

[0032] After the reaction is complete, open the control valve 7, and the prepared slag material can be discharged through the discharge pipe 6.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
