Description
Technical Field
[0001] This utility model belongs to the field of steel slag treatment technology, specifically a hydrocyclone for steel slag treatment. Background Technology
[0002] A hydrocyclone is a high-efficiency separation device based on the principle of centrifugal force for solid-liquid separation, liquid-liquid separation, or particle classification. It is widely used in mining, metallurgy, chemical industry, environmental protection, petroleum, food and other fields. Its core function is to generate centrifugal force through high-speed rotating fluid to separate substances of different densities or particle sizes.
[0003] In existing technology, steel slag slurry is introduced into the hydrocyclone through its tangential inlet under pressure, forming a high-speed rotating vortex. During this rotation, solid particles or high-density liquid in the slurry move towards the hydrocyclone wall due to centrifugal force and spiral downwards along the wall, eventually being discharged from the sand outlet. Low-density liquid or fine particles, on the other hand, move towards the center, forming an upward internal vortex that is discharged from the overflow outlet. However, long-term use and observation have revealed that during the separation of steel slag slurry using a hydrocyclone, slurry agglomeration occurs, leading to uneven centrifugal force and hindering efficient solid-liquid separation.
[0004] Therefore, this utility model provides a hydrocyclone for steel slag treatment. Utility Model Content

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 4 As shown in the figure, a hydrocyclone for steel slag treatment according to an embodiment of the present invention includes a cylindrical body 1; a conical body 11 is fixedly connected to the bottom of the cylindrical body 1; the conical body 11 has a conical structure; a feed pipe 12 is fixed to the middle of the side wall of the cylindrical body 1; a flow equalization component is provided in the middle of the inner side wall of the cylindrical body 1; the flow equalization component is connected to the feed pipe 12; a collecting pipe 13 is fixedly connected to the bottom of the conical body 11; a flow dividing component is provided in the middle of the inner side wall of the collecting pipe 13; the top of the collecting pipe 13... The cylindrical body 1 has a settling inlet 14; an overflow outlet 15 is provided at the top of the cylindrical body 1; a layering component is provided at the top of the overflow outlet 15; an agitator is provided at the bottom of the layering component; the agitator is located inside the conical body 11; the conical body 11, the collecting pipe 13, the settling inlet 14, the overflow outlet 15, and the cylindrical body 1 are connected; the steel slag slurry to be treated is injected tangentially into the uniform flow component at a certain pressure through the feed pipe 12 under the action of the pump. When the operator starts the uniform flow component, the uniform flow is activated. The component agitates the steel slag slurry inside, breaking up any clumps. The slurry then flows out of the equalizing component and along the inner wall of the conical cylinder 11. At this point, the slurry forms a high-speed rotating vortex inside the conical cylinder 11, generating a strong centrifugal force. Under this centrifugal force, the steel slag particles, due to their higher density, experience a greater centripetal force and are thrown towards the inner wall of the conical cylinder 11. The steel slag particles then move downwards along the inner wall of the conical cylinder 11, eventually passing through the sand settling port 1. 4. The liquid flows into the collection pipe 13 and is diverted and discharged by the diversion component, forming an underflow. Because the liquid has a lower density, it experiences less centrifugal force and mainly moves towards the center of the conical cylinder 11. An internal spiral vortex is formed at the center of the conical cylinder 11 and moves upward. It then flows into the stratification component through the overflow port 15 for stratification and discharge, forming an overflow. During the separation of steel slag slurry, the vortex drives the stirring component to rotate, causing the stirring component to stir the steel slag slurry inside the conical cylinder 11.
[0026] like Figures 1 to 3As shown, the flow equalization assembly includes a threaded pipe 2; the threaded pipe 2 is fixed on the inner wall of the cylindrical body 1; the conical body 11, the feed pipe 12, and the threaded pipe 2 are connected; multiple motors 21 are mounted on the top of the cylindrical body 1; the multiple motors 21 are arranged in a circular array on the top of the cylindrical body 1; a movable shaft 22 is fixed to the output end of the motor 21; multiple stirring rods 23 are fixed in the middle of the side wall of the movable shaft 22; the stirring rods 23 rotate inside the threaded pipe 2; the steel slag slurry to be treated is injected tangentially into the threaded pipe 2 through the feed pipe 12 at a certain pressure under the action of the pump. At this time, the operator starts multiple motors 21, which drive the movable shaft 22 to rotate. When the movable shaft 22 rotates, it drives multiple stirring rods 23 to rotate inside the threaded pipe 2. When the steel slag slurry flows inside the threaded pipe 2, it is dispersed by multiple rotating stirring rods 23. The dispersed slurry then passes through... The threaded tube 2 flows into the conical cylinder 11. At this time, the steel slag slurry flowing along the inner wall of the threaded tube 2 will quickly flow towards the inner wall of the conical cylinder 11 under the action of centrifugal force. This step, by setting the threaded tube 2, can guide the steel slag slurry to flow along the spiral path, reduce the "dead zone" or "short circuit" phenomenon in the flow field, and make the slurry more evenly distributed in the entire hydrocyclone. Moreover, the spiral structure of the threaded tube 2 will disturb the slurry, increase the turbulence of the slurry, and make the particles in the steel slag slurry more fully mixed with the liquid, reducing local concentration differences. The threaded tube 2, motor 21, movable shaft 22 and stirring rod 23 can break up the agglomerates by mechanical force, so that the steel slag particles are evenly dispersed in the liquid, eliminating the concentration gradient of the slurry, so that it reaches a uniform state before entering the conical cylinder 11, reducing the situation of unstable separation due to excessively high or low local concentration, and improving separation efficiency.
[0027] like Figures 1 to 3 As shown, the layered assembly includes a first overflow pipe 3; the first overflow pipe 3 is fixed to the top of the cylindrical body 1; the first overflow pipe 3 covers the outside of the overflow port 15; multiple connecting plates 31 are fixed to the bottom of the first overflow pipe 3; a second overflow pipe 32 is fixed to the middle of the side wall of the connecting plate 31; the second overflow pipe 32 is located inside the first overflow pipe 3; the cylindrical body 1, the conical body 11, the first overflow pipe 3 and the second overflow pipe 32 are connected; because the liquid has a lower density, it experiences less centrifugal force and will form an internal spiral vortex at the center of the conical body 11, moving upward and flowing into the first overflow pipe 3 or the second overflow pipe 32 according to different particle sizes. This step, by setting the first overflow pipe 3 and the second overflow pipe 32, can set multiple graded outlets at the top of the hydrocyclone, each outlet corresponding to a different separation particle size range, thereby achieving a finer separation effect and realizing multi-stage separation, improving separation accuracy.
[0028] like Figures 1 to 3As shown, the agitation assembly includes multiple elastic bands 4; the elastic bands 4 are fixed to the bottom of the connecting plate 31; the elastic bands 4 are made of deformable material; a load-bearing block 41 is fixed to the bottom of the elastic band 4; a fixing rod 42 is fixed to the bottom of the load-bearing block 41; both the load-bearing block 41 and the fixing rod 42 are located inside the conical cylinder 11; when the steel slag slurry forms a vortex inside the conical cylinder 11 due to centrifugal force, the vortex will drive the multiple elastic bands 4 to rotate, causing the elastic bands 4 to drive the load-bearing block 41 and the fixing rod 42 at the bottom to rotate. At this time, the fixing rod 42 will stir the steel slag slurry during the rotation. This step, by setting the elastic bands 4, the load-bearing block 41 and the fixing rod 42, can generate additional shear force on the steel slag slurry, break up particle agglomeration, make the particles more evenly dispersed in the liquid, and enhance the mixing effect. At the same time, the rotation of the elastic bands 4, the load-bearing block 41 and the fixing rod 42 can enhance the degree of vortex in the slurry, allowing more particles to be exposed to the action of centrifugal force, further improving the separation efficiency.
[0029] like Figure 2 and Figure 4 As shown, the diversion assembly includes a fixed shaft 5; the fixed shaft 5 is fixed to the inner wall of the collecting pipe 13; a diversion plate 51 is rotatably connected to the middle of the side wall of the fixed shaft 5; the diversion plate 51 is located below the sand settling port 14; multiple dispersing plates 52 are fixedly connected to the middle of the side wall of the diversion plate 51; when steel slag particles flow into the collecting pipe 13 through the sand settling port 14, they will fall onto the surfaces of the diversion plate 51 and the dispersing plates 52. At this time, the dispersing plates 52 will be subjected to the thrust of the falling steel slag particles. Because the diversion plate 51 and the fixed shaft 5 are rotatably connected, the multiple dispersing plates 52 will drive the diversion plate 51 to rotate on the fixed shaft 5. This step, by setting the fixed shaft 5, the diversion plate 51 and the dispersing plates 52, can reduce the deposition of steel slag particles in the sand settling port 14, so that the particles can be discharged smoothly, reducing the risk of blockage and improving the discharge efficiency. Moreover, this setting can disperse the scouring force of steel slag particles on the collecting pipe 13, reduce local wear, and extend the service life of the equipment.
[0030] like Figure 2 and Figure 3 As shown, an elastic ring 6 is fixed between the cylindrical body 1 and the threaded pipe 2; the elastic ring 6 is made of elastic material; this step, by setting the elastic ring 6, can absorb and buffer the vibration caused by uneven flow when the threaded pipe 2 is conveying steel slag slurry, and reduce the transmission of vibration to the cylindrical body 1 and surrounding equipment.
[0031] like Figure 1 and Figure 2 As shown, an observation window 7 is provided in the middle of the side wall of the conical cylinder 11; the observation window 7 is made of transparent material; by setting the observation window 7, the staff can directly observe the flow state of the steel slag slurry inside the hydrocyclone, including the vortex shape, flow velocity distribution, etc., and detect abnormalities in time.
[0032] like Figure 2 and Figure 4 As shown, the dispersing plate 52 is set in an arc shape. This step can more effectively disperse the steel slag particles through the unique arc design of the dispersing plate 52, achieving high-efficiency dispersing. Moreover, the arc-shaped dispersing plate 52 handles the particles more gently during the dispersing process, thus reducing wear and damage to the equipment, helping to extend the service life of the equipment and reduce maintenance costs.
[0033] Working principle: Under the action of the pump, the steel slag slurry to be treated is injected tangentially into the uniform flow assembly through the feed pipe 12 at a certain pressure. When the operator starts the uniform flow assembly, it agitates the steel slag slurry inside, breaking up any clumps. Subsequently, the steel slag slurry flows out of the uniform flow assembly and flows along the inner wall of the conical cylinder 11. At this time, the slurry forms a high-speed rotating vortex inside the conical cylinder 11, generating a strong centrifugal force. Under the action of centrifugal force, the steel slag particles, due to their higher density, are subjected to a greater centripetal force and are thrown towards the inner wall of the conical cylinder 11. At this time, the steel slag particles move downward along the inner wall of the conical cylinder 11. Finally, the slag flows into the collection pipe 13 through the sand outlet 14 and is diverted and discharged by the diversion component, forming an underflow. Because the liquid has a lower density and experiences less centrifugal force, it mainly moves towards the center of the conical cylinder 11, forming an internal spiral vortex that moves upwards. This vortex then flows into the stratification component through the overflow outlet 15 for stratified discharge, forming an overflow. During the separation of the steel slag slurry, the vortex drives the agitator to rotate, causing it to agitate the steel slag slurry inside the conical cylinder 11. The steel slag slurry to be treated is then pumped tangentially into the threaded pipe 2 through the feed pipe 12 at a certain pressure. The staff starts multiple motors 21, which drive the movable shaft 22 to rotate. The rotation of the movable shaft 22 drives multiple stirring rods 23 to rotate inside the threaded tube 2. As the steel slag slurry flows inside the threaded tube 2, it is dispersed by the rotating stirring rods 23. The dispersed slurry then flows through the threaded tube 2 into the conical cylinder 11. At this time, the steel slag slurry flowing along the inner wall of the threaded tube 2 will rapidly flow towards the inner wall of the conical cylinder 11 under the action of centrifugal force. Because the liquid has a lower density, it experiences less centrifugal force and forms an internal spiral vortex at the center of the conical cylinder 11, moving upwards and flowing into the first... Inside the overflow pipe 3 or the second overflow pipe 32, when the steel slag slurry forms a vortex inside the conical cylinder 11 due to centrifugal force, the vortex will drive multiple elastic bands 4 to rotate, causing the elastic bands 4 to drive the bottom load block 41 and the fixed rod 42 to rotate. At this time, the fixed rod 42 will stir the steel slag slurry during rotation. When the steel slag particles flow into the collection pipe 13 through the sand settling port 14, they will fall onto the surface of the diversion plate 51 and the dispersing plate 52. At this time, the dispersing plate 52 will be subjected to the thrust of the falling steel slag particles. Because the diversion plate 51 and the fixed shaft 5 are rotatably connected, the multiple dispersing plates 52 will drive the diversion plate 51 to rotate on the fixed shaft 5.
