Description

Technical Field

[0001] The present invention relates to the field of metallurgical technology, and particularly to a slag basin for cooling high-titanium slag and a method for using the same. Background Art

[0002] In the process of producing titanium dioxide by the chlorination method using ilmenite as a raw material, high-titanium slag, as an important intermediate product, its cooling process has an important impact on subsequent production processes. By rapidly cooling the molten high-titanium slag, the content of rutile phase in the high-titanium slag can be effectively reduced, thereby improving the acidolysis rate of the titanium slag and further enhancing the efficiency of the entire production process. However, there are some problems to be solved urgently in the existing high-titanium slag cooling and demoulding technologies.

[0003] First of all, the slag basin, as a commonly used device for cooling high-titanium slag, is usually a casting or a welded part. When the molten high-titanium slag enters the slag basin, it will cause a strong thermal shock to the slag basin. This thermal shock will cause the temperature of the slag basin to rise rapidly, and then cause the deformation or cracking of the slag basin. Although laying a layer of high-titanium slag at the bottom of the slag basin in advance can slow down the thermal shock to a certain extent, this measure cannot effectively inhibit the deformation and cracking of the slag basin fundamentally. At present, the service life of the slag basin is short. Frequent replacement of the slag basin not only increases the production cost, but also affects the continuity of production.

[0004] Secondly, in the process of removing the high-titanium slag from the slag basin, the commonly used method at present is to place a pair of metal wedges at the edge of the slag basin to form wedge holes during the condensation of the molten high-titanium slag. Subsequently, a lifting fixture is placed at the wedge holes to lift the solidified high-titanium slag out of the slag basin. However, during the lifting process, the high-titanium slag near the wedge holes needs to bear a large stress, which makes the high-titanium slag prone to breakage or loss at the wedge holes. Once the wedge holes are damaged, the high-titanium slag needs to be broken before it can be removed from the slag basin, which not only increases the complexity of the operation, but also greatly reduces the production efficiency. It can be seen that the existing method of setting wedge holes for demoulding has low reliability and is prone to cause breakage of high-titanium slag and a decrease in production efficiency.

[0005] The problems of short service life of the slag basin and low demoulding reliability in the prior art seriously affect the production efficiency of the high-titanium slag cooling and removal links.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0007] One of the purposes of the present invention is to provide a slag basin for cooling high-titanium slag, aiming to solve at least one of the above technical problems in the prior art.

[0008] Another purpose of the present invention is to provide a method for using a slag basin for cooling high-titanium slag.

[0009] To achieve the above object of the present invention, the following technical solutions are specifically adopted:

[0010] A slag basin for cooling high-titanium slag according to a first aspect of the present invention includes a slag hopper and a hanging weight.

[0011] The slag hopper is in the shape of an ark with a large top and a small bottom, and the slag hopper has a double-layer structure; the hanging weight is arranged at the central position of the slag hopper.

[0012] A protective coating is provided on the surface of the hanging weight.

[0013] Further, the double-layer structure includes an inner layer and an outer layer.

[0014] The inner layer is made of heavy refractory bricks stacked, and the outer layer is composed of structural steel welded parts.

[0015] Further, lifting hooks and reinforcing ribs are provided on the outer wall of the structural steel welded parts.

[0016] Further, in the inner cavity of the slag hopper, the bottom size is 2000 - 3000 mm in length, 1000 - 2000 mm in width, and 800 - 1000 mm in height.

[0017] In the inner cavity of the slag hopper, the top size is 3500 - 4500 mm in length and 3000 - 4000 mm in width.

[0018] Further, the hanging weight is a metal casting and is composed of a lifting ring and a square platform.

[0019] The lifting ring is arranged above the square platform, and the square platform is in the shape of a truncated pyramid with a small top and a large bottom.

[0020] The top length of the square platform is 200 - 300 mm, the width is 150 - 200 mm, and the height is 600 - 800 mm.

[0021] The bottom length of the square platform is 600 - 800 mm and the width is 500 - 600 mm.

[0022] Further, the hanging weight is a metal casting and is composed of a lifting ring and a frustum of a cone.

[0023] The lifting ring is arranged above the frustum of the cone, and the frustum of the cone is in the shape of an inverted mushroom with a small top and a large bottom.

[0024] The lower diameter of the frustum of the cone is 600 - 800 mm, the upper diameter is 200 - 300 mm, and the height is 600 - 800 mm.

[0025] Further, the protective coating contains first high-titanium slag.

[0026] And / or, a second high-titanium slag layer is provided on the inner surface of the slag hopper.

[0027] And / or, the thickness of the second high-titanium slag layer is 100 - 300 mm.

[0028] Furthermore, the particle size of the first high-titanium slag is less than 100 mesh.

[0029] Furthermore, the particle size of the second high-titanium slag in the second high-titanium slag layer is less than 2 mesh.

[0030] In the second aspect of the present invention, a method for using the slag basin is provided. Molten third high-titanium slag is poured into the slag basin. After the upper surface layer of the third high-titanium slag solidifies, cooling water is poured from the hanging weight to accelerate cooling. After the third high-titanium slag is completely solidified, the third high-titanium slag is lifted from the hanging weight and broken, and then the hanging weight is removed.

[0031] Compared with the prior art, the present invention has at least the following beneficial effects:

[0032] The slag basin for cooling high-titanium slag provided by the present invention adopts a double-layer structure, which can effectively reduce the thermal impact force generated when the molten high-titanium slag enters, and avoid deformation or cracking caused by local stress concentration. At the same time, the hanging weight arranged in the center of the slag hopper enhances the overall structural stability, and the protective coating on its surface further provides heat insulation, corrosion resistance and wear resistance protection, significantly extending the service life of the slag basin. In addition, the design of the hanging weight abandons the traditional wedge-hole demoulding method, enabling the high-titanium slag to naturally form a stable connection structure during the condensation process, with uniform stress during lifting, reducing the risk of breakage and improving the reliability of demoulding. While extending the service life of the slag basin, the present invention significantly improves the reliability of high-titanium slag demoulding, providing a more efficient and stable solution for the cooling and removal of high-titanium slag.

[0033] The method for using the slag basin of the present invention accelerates the cooling process by pouring cooling water from the hanging weight after the upper surface layer of the high-titanium slag solidifies, significantly shortening the time for the high-titanium slag to change from the molten state to the completely solidified state and improving production efficiency. At the same time, this method uses the hanging weight for hoisting and removing the high-titanium slag, simplifies the demoulding operation, reduces the risk of high-titanium slag breakage caused by damage to the wedge hole, and reduces the manual operation intensity and production cost. The optimized cooling and demoulding methods not only improve the safety and reliability of demoulding, but also reduce the risk of equipment damage and production interruption, significantly improving the overall production efficiency of the high-titanium slag cooling and removal process, and providing efficient and stable technical support for titanium dioxide production.

Specific embodiments

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0040] In the following text, the terms "including", "having", and their cognates that can be used in various embodiments of the present invention are only intended to represent specific features, numbers, steps, operations, elements, components, or combinations of the foregoing items, and should not be construed as first excluding the existence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing items or increasing the possibility of one or more features, numbers, steps, operations, elements, components, or combinations of the foregoing items.

[0041] The first aspect of the present invention provides a slag basin for cooling high-titanium slag, including a slag hopper 10 and a hanging weight 20. The slag hopper 10 is in the shape of an ark with a large top and a small bottom, and the hanging weight 20 is arranged at the central position of the slag hopper 10. A protective coating 30 is provided on the surface of the hanging weight 20.

[0042] The slag pot for cooling high-titanium slag provided by the present invention adopts the structure of an ark-shaped slag hopper 10 with a larger upper part and a smaller lower part, which can effectively slow down the thermal impact force generated when the molten high-titanium slag enters, and avoid deformation or cracking caused by local stress concentration. At the same time, the hanging weight 20 arranged in the center of the slag hopper 10 enhances the overall structural stability, and the protective coating 30 on its surface further provides heat insulation, corrosion resistance and wear resistance protection, significantly extending the service life of the slag pot. In addition, the design of the hanging weight 20 abandons the traditional wedge-hole demoulding method, enabling the high-titanium slag to naturally form a stable connection structure during the condensation process. When lifted out, the force is evenly distributed, reducing the risk of breakage and improving the reliability of demoulding. The present invention not only extends the service life of the slag pot, but also significantly improves the reliability of high-titanium slag demoulding, providing a more efficient and stable solution for the cooling and removal of high-titanium slag.

[0043] The slag pot of the present invention adopts the structure of an ark-shaped slag hopper 10 with a larger upper part and a smaller lower part, and this design can effectively slow down the thermal impact force generated when the molten high-titanium slag enters the slag pot. Compared with the traditional slag pot, it avoids the problems of deformation or cracking caused by local stress concentration. In addition, the protective coating 30 arranged on the surface of the hanging weight 20 not only provides heat insulation protection, but also enhances the corrosion resistance and wear resistance of the hanging weight. These improvement measures work together to significantly extend the service life of the slag pot and reduce the frequent replacement and maintenance costs caused by slag pot damage.

[0044] The slag pot design of the present invention abandons the traditional demoulding method of setting wedge holes at the edge of the slag pot, and realizes the removal of high-titanium slag through the hanging weight 20. The hanging weight 20 is located in the center of the slag hopper 10, and its structural design enables the high-titanium slag to naturally form a stable connection structure during the condensation process, avoiding the problem of high-titanium slag breakage caused by stress concentration at the traditional wedge holes. During the lifting process, the force on the high-titanium slag is more evenly distributed, reducing the risk of breakage caused by excessive stress. In addition, the protective coating 30 on the surface of the hanging weight 20 further reduces the adhesion between the high-titanium slag and the hanging weight 20, making the demoulding process smoother, improving the reliability of demoulding, and reducing the decline in production efficiency caused by demoulding failure.

[0045] Furthermore, the slag hopper 10 has a double-layer structure; the double-layer structure includes an inner layer and an outer layer.

[0046] The inner layer is made of heavy refractory bricks stacked, and the outer layer is composed of structural steel welded parts. The inner refractory bricks have excellent high-temperature resistance and heat insulation performance, can withstand the high-temperature impact of molten high-titanium slag and slow down the heat conduction to the outside, protecting the outer structural steel components from the influence of high temperature; the outer structural steel components provide high-strength support for the slag hopper 10 to ensure its structural integrity when bearing the weight and stress of high-titanium slag during the cooling process. This double-layer structure gives full play to the advantages of refractory bricks and structural steel, effectively reducing the risk of deformation and damage caused by thermal shock, and significantly improving the service life and reliability of the slag hopper 10.

[0047] On the one hand, the heavy-duty refractory brick has good heat insulation performance, which can effectively slow down the thermal shock borne by the outer metal weldment; on the other hand, it has excellent erosion resistance and can resist the erosion of molten high-titanium slag, thus significantly improving the erosion resistance of the slag basin.

[0048] Furthermore, a lifting hook 111 and a reinforcing rib 112 are provided on the outer wall of the structural steel weldment. The lifting hook 111 provides a convenient connection for the hoisting and movement of the slag bucket. By performing the hoisting operation at the lifting lug 20, the solidified high-titanium slag can be quickly and stably lifted out of the slag bucket, while avoiding direct contact with the internal structure of the slag bucket and possible damage. This design not only improves the efficiency and safety of demoulding, but also reduces the risk of high-titanium slag breakage caused by improper hoisting.

[0049] The setting of the reinforcing rib 112 can significantly enhance the structural strength and stability of the outer wall of the slag basin. When the slag basin bears the high-temperature impact of molten high-titanium slag and the stress generated during the cooling process, the reinforcing rib 112 can effectively disperse the stress and prevent the outer wall from deforming or cracking. In addition, the reinforcing rib 112 can also improve the overall rigidity of the slag bucket, extend its service life, and ensure the reliability and stability of the slag bucket during long-term use.

[0050] The combination of the lifting hook 111 and the reinforcing rib 112 not only improves the hoisting and operating performance of the slag bucket, but also enhances its structural strength and durability. This design enables the slag basin to operate stably under complex working conditions of high temperature and high stress, while simplifying the operation process, reducing production costs, and improving production efficiency.

[0051] Furthermore, in the inner cavity of the slag bucket 10, the bottom size is 2000 - 3000 mm in length, 1000 - 2000 mm in width, and 800 - 1000 mm in height.

[0052] In the inner cavity of the slag bucket 10, the top size is 3500 - 4500 mm in length and 3000 - 4000 mm in width.

[0053] Furthermore, the lifting lug 20 is a metal casting and is composed of a lifting ring 21 and a square platform 22.

[0054] The lifting ring 21 is arranged above the square platform 22, and the square platform 22 is a frustum-shaped structure with a smaller top and a larger bottom. The lifting lug 20 adopts the frustum-shaped structure of the square platform 22. When the molten high-titanium slag solidifies, a connection structure matching the structure of the square platform 22 will be formed. During hoisting, the connection structure is in close contact with the lifting lug 20, and the solidified high-titanium slag can be stably lifted out of the slag bucket, thus significantly improving the reliability of demoulding.

[0055] The top length of the square platform 22 is 200 - 300 mm, the width is 150 - 200 mm, and the height is 600 - 800 mm.

[0056] The bottom length of the square platform 22 is 600 - 800 mm, and the width is 500 - 600 mm.

[0057] Further, the hanging weight 20 is a metal casting, composed of a lifting ring 21 and a frustum 23. The lifting ring 21 is arranged above the frustum 23. The frustum 23 has an inverted mushroom-like structure with a smaller upper part and a larger lower part. The lower diameter of the frustum 23 is 600 - 800 mm, the upper diameter is 200 - 300 mm, and the height is 600 - 800 mm.

[0058] Further, the protective coating 30 contains first high-titanium slag. Coating the surface of the hanging weight 20 with the protective coating 30 can effectively extend the service life of the hanging weight 20. At the same time, using an organic binder and first high-titanium slag to manufacture the protective coating 30 avoids the infiltration of metal ions, thereby preventing pollution to the high-titanium slag.

[0059] In the specific implementation process, the organic binder uses starch. Add starch to water and stir evenly to obtain a colloid. At the same time, crush the first high-titanium slag into a powder with a particle size less than 100 mesh. Mix the above colloid and high-titanium slag powder evenly to obtain a plastic dough. Coat the plastic dough evenly on the surface of the hanging weight 20 and dry it to obtain the protective coating 30.

[0060] In another implementation process, the organic binder is carboxymethyl cellulose. Dissolve carboxymethyl cellulose in water to obtain an adhesive. Subsequently, add first high-titanium slag powder with a particle size less than 100 mesh, mix evenly to obtain a plastic dough. Coat the plastic dough evenly on the surface of the hanging weight 20 and dry it to obtain the protective coating 30.

[0061] And / or, the inner surface of the slag bucket 10 is provided with a second high-titanium slag layer, which can not only further reduce the thermal shock borne by the slag bucket, but also enhance its erosion resistance, ensuring that the slag bucket has a long service life.

[0062] And / or, the thickness of the second high-titanium slag layer is 100 - 300 mm. In the specific implementation process, in order to further extend the service life of the slag bucket, lay granular second high-titanium slag with a thickness of 200 - 300 mm at the bottom of the slag bucket 10, and lay second high-titanium slag with a thickness of 100 - 200 mm on the wall of the slag bucket 10 to form the second high-titanium slag layer 40.

[0063] Further, the particle size of the first high-titanium slag is less than 100 mesh.

[0064] Further, the particle size of the second high-titanium slag is less than 2 mesh.

[0065] In the second aspect of the present invention, a method for using the slag pot is provided. Molten third high-titanium slag is poured into the slag pot. After the upper surface layer of the third high-titanium slag solidifies, cooling water is poured from the lifting weight 20 to accelerate cooling. After the third high-titanium slag is completely solidified, the third high-titanium slag is lifted from the lifting weight 20 and can be removed outside the slag bucket.

[0066] The method for using the slag pot of the present invention significantly shortens the time for the high-titanium slag to change from the molten state to complete solidification and improves production efficiency by pouring cooling water from the lifting weight 20 after the upper surface layer of the high-titanium slag solidifies, thereby accelerating the cooling process. At the same time, this method uses the lifting weight 20 for hoisting and removing the high-titanium slag, simplifies the demolding operation, reduces the risk of high-titanium slag breakage caused by damage to the wedge holes, and reduces the manual operation intensity and production cost. The optimized cooling and demolding methods not only improve the safety and reliability of demolding, but also reduce the risk of equipment damage and production interruption, significantly enhancing the overall production efficiency of the high-titanium slag cooling and removal processes, and providing efficient and stable technical support for titanium dioxide production.

[0067] Specifically, after the upper surface layer of the third high-titanium slag of the present invention solidifies, cooling water is poured from the lifting weight 20. This cooling method can quickly reduce the temperature of the high-titanium slag, enabling the internal heat to be rapidly conducted and dissipated. Compared with traditional natural cooling or single air cooling, the direct contact with cooling water significantly increases the cooling rate, shortens the time for the high-titanium slag to change from the molten state to complete solidification, and thus improves production efficiency.

[0068] After the high-titanium slag is completely solidified, the high-titanium slag is lifted and removed from the slag pot through the lifting weight 20. Since the lifting weight 20 is located at the center of the slag bucket 10 and the structure of the slag pot is optimized, the high-titanium slag can shrink uniformly during the condensation process, reducing adhesion to the inner wall of the slag bucket. The design of the lifting weight 20 enables the high-titanium slag to be evenly stressed when lifted out, further improving the safety and reliability of demolding and reducing the risk of high-titanium slag breakage or slag pot damage caused by improper demolding. Pouring water for cooling from the lifting weight 20 can not only quickly reduce the temperature of the high-titanium slag, but also cool the lifting weight 20 at the same time. Since the lifting weight 20 is a metal part with better heat conduction performance than the high-titanium slag, by virtue of the heat transfer effect of the lifting weight 20, the cooling process of the high-titanium slag can be accelerated, thereby shortening the cooling time and improving production efficiency. In addition, the cooling water can also penetrate downward through the protective coating 30 or the high-titanium slag laid on the four walls of the slag bucket 10 to cool the inside or the surroundings of the high-titanium slag, further shortening the cooling time and enhancing production efficiency.

[0069] The usage method of the present invention abandons the complex demolding method of setting wedge holes at the edge of the slag basin, and directly uses the lifting weight 20 for hoisting and removal. This design simplifies the operation process, reduces the cumbersome steps of crushing high-titanium slag due to damage to the wedge holes, reduces the manual operation intensity and production cost, and at the same time improves the continuity and stability of production.

[0070] By accelerating cooling and simplifying the demolding operation, the present invention not only shortens the cooling and removal time of high-titanium slag, but also reduces production interruptions caused by equipment damage or operation errors. This optimized usage method can significantly improve the overall production efficiency of the high-titanium slag cooling and demolding links, and provides more efficient and stable technical support for the industrial production of titanium dioxide by the chloride process.
