Description

Technical Field

[0001] This utility model relates to the field of high-level guide channel technology, and in particular to a nickel chloride crystallization high-level guide channel. Background Technology

[0002] In the crystallization process of nickel chloride, the guide channel is a key piece of equipment for conveying crystal slurry or solution. It drives the material flow through the gravitational potential energy generated by the high elevation difference and is widely used in crystallization production systems in industries such as chemical and metallurgy. Nickel chloride crystals usually have a certain viscosity and contain suspended crystal particles. During the conveying process, the flow rate and flow state must be strictly controlled to avoid crystal breakage, sedimentation blockage, or impact on purity.

[0003] In certain special production environments, such as multi-story plants in large chemical industrial parks, mountainous plant areas, or specific process layouts, there is a significant height difference between the upstream and downstream equipment in nickel chloride crystallization processing, resulting in a substantial increase in the vertical drop of the flow path (in some scenarios, the drop can exceed 5 meters). To adapt to this large drop condition, the flow guidance system typically needs to be designed as a multi-stage series flow channel structure. By guiding the flow step by step, the vertical drop of a single stage is reduced, thereby minimizing kinetic energy loss and equipment wear caused by high-speed material impact.

[0004] To address the aforementioned issues, the industry has attempted to incorporate flow-blocking structures, such as fixed baffles or grids, within the flow channel. However, these structures are mostly rigidly fixed designs, making it impossible to flexibly adjust the flow-blocking intensity, and they are prone to creating dead zones for material accumulation at the corners. Therefore, this utility model proposes a novel solution. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-level guide channel for nickel chloride crystallization. This can solve the problem that the industry has tried to set up flow-blocking structures in the guide channel, such as fixed baffles and grids, but these structures are mostly rigid fixed designs, which cannot flexibly adjust the flow-blocking intensity and are prone to forming dead corners for material accumulation at the edges and corners.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-level guide channel for nickel chloride crystallization, comprising a first connecting pipe, a first guide channel fixedly connected to the upper end of the first connecting pipe, and a second guide channel fixedly connected to the right side of the first connecting pipe; A first flow deflector is fixedly connected to the right eccentric part of the first flow guide channel, and a second flow deflector is fixedly connected to the upper eccentric part of the second flow guide channel. A second connecting pipe is fixedly connected to the middle of the first guide channel; The inner wall of the second guide channel is provided with a guide channel, and a guide block is fixedly connected to the inner wall of the second guide channel.

[0007] Preferably, the second guide channel is inclined and disposed on the right side of the first guide channel.

[0008] Preferably, the interior of the first flow deflector is rotatably connected to a first rotating shaft, and a plurality of first flow deflectors are fixedly connected to the surface of the first rotating shaft.

[0009] Preferably, the interior of the second flow deflector is rotatably connected to a second rotating shaft, and a plurality of second flow deflectors are fixedly connected to the surface of the second rotating shaft.

[0010] Preferably, the guide groove is spiral-shaped.

[0011] Preferably, the guide block is spiral-shaped.

[0012] Preferably, both the first connecting pipe and the second connecting pipe are spherical.

[0013] Preferably, both the first flow barrier and the second flow barrier are cylindrical shells.

[0014] Preferably, a feed pipe is fixedly connected to the upper end of the first guide channel.

[0015] Preferably, a discharge pipe is fixedly connected to the right side of the second guide channel.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-level guide channel for nickel chloride crystallization addresses the issue of large drop in the flow path under special environments. It forms a multi-stage series structure through the first guide channel and the inclined second guide channel. Combined with the expansion and buffering effect of the spherical first and second connecting pipes, it can effectively reduce the flow velocity impact caused by single-stage drop. At the same time, the eccentrically set first and second flow-blocking hoods and the first and second flow-blocking plates inside the second flow-blocking hoods can dynamically contact and buffer the kinetic energy of the material, preventing crystal particles from breaking due to high-speed impact on the tank wall or turbulence, and significantly improving the particle size uniformity of the nickel chloride crystallization product.

[0017] 2. Compared with traditional rigid flow-blocking structures such as fixed baffles and grids, the first and second flow-blocking plates rotating around the first and second rotating shafts can automatically adjust their rotation speed according to the material flow rate. When the flow rate increases, the rotation speed of the flow-blocking plates increases, and the flow-blocking intensity increases accordingly. Conversely, it weakens, thus achieving adaptive flow-blocking for nickel chloride crystal materials with different flow rates and concentrations. This solves the problem that fixed structures cannot flexibly adapt to changes in working conditions. Attached Figure Description

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figures 1-6This utility model provides a technical solution: a high-level guide channel for nickel chloride crystallization, including a first connecting pipe 1, a first guide channel 2 fixedly connected to the upper end of the first connecting pipe 1, a second guide channel 4 fixedly connected to the right side of the first connecting pipe 1, a first flow-blocking shroud 7 fixedly connected to the eccentric part of the right side of the first guide channel 2, a second flow-blocking shroud 8 fixedly connected to the eccentric part of the upper end of the second guide channel 4, a second connecting pipe 6 fixedly connected to the middle part of the first guide channel 2, a guide channel 9 opened on the inner wall of the second guide channel 4, and a guide block 10 fixedly connected to the inner wall of the second guide channel 4.

[0025] The second guide channel 4 is inclined and set to the right side of the first guide channel 2.

[0026] The first flow deflector 7 is rotatably connected to a first rotating shaft 11, and a plurality of first flow deflectors 12 are fixedly connected to the surface of the first rotating shaft 11.

[0027] The second flow deflector 8 is rotatably connected to a second rotating shaft 13, and a plurality of second flow deflectors 14 are fixedly connected to the surface of the second rotating shaft 13.

[0028] The guide channel 9 is spiral-shaped.

[0029] The guide block 10 is spiral-shaped.

[0030] Both the first connecting pipe 1 and the second connecting pipe 6 are spherical.

[0031] Both the first flow barrier 7 and the second flow barrier 8 are cylindrical shells.

[0032] The upper end of the first guide channel 2 is fixedly connected to the feed pipe 3.

[0033] The discharge pipe 5 is fixedly connected to the right side of the second guide channel 4.

[0034] When using this device, the working principle of the nickel chloride crystallization high-level guide channel is based on the design of combining multi-stage flow guidance and dynamic flow obstruction. Through the synergistic effect of structured flow channel guidance and adjustable flow obstruction components, stable transportation of nickel chloride crystallization materials is achieved in scenarios with large drop.

[0035] Nickel chloride crystals first enter the first guide channel 2 through the feed pipe 3 and flow downward along the channel under the gravity generated by the high elevation difference. When the material flows through the middle of the first guide channel 2, some of the material passes through the spherical shell-shaped second connecting pipe 6. The spherical shell structure uses the volume expansion effect to reduce the local flow velocity and avoid the crystals from breaking due to concentrated impact.

[0036] The remaining material continues to flow to the right along the first guide channel 2. When it reaches the first flow-blocking shroud 7 at the right eccentric position, it will impact the first flow-blocking plate 12 inside the cylindrical shell. Since the first flow-blocking shroud 7 and the first rotating shaft 11 are eccentrically set, the impact force of the material drives multiple first flow-blocking plates 12 to rotate around the first rotating shaft 11. Through the dynamic contact between the plate and the material, the kinetic energy of the material is buffered, and the formation of fixed dead corners is avoided, effectively suppressing the generation of turbulence. At the same time, the flow-blocking intensity is adaptively adjusted by the rotation speed to adapt to the conveying of materials with different flow rates.

[0037] After being regulated by the first flow-blocking shroud 7, the material enters the second flow-guiding channel 4 through the spherical first connecting pipe 1. Because the second flow-guiding channel 4 is inclined, the material continues to flow to the right under the combined action of gravity and the inclined slope. When it flows through the second flow-blocking shroud 8 at the upper eccentric position, it impacts the second flow-blocking plate 14 on the surface of the second rotating shaft 13. Similarly, the eccentric rotation structure achieves secondary flow blocking, further reducing the flow velocity and stabilizing the flow state, forming a multi-level coordinated regulation with the first flow-blocking shroud 7.

[0038] Inside the second guide channel 4, the spiral guide channel 9 and the guide block 10 form a composite guiding structure. The guide channel 9 extends the flow distance through the spiral path, while the guide block 10 forms a lateral guiding force on the material, so that the material is smoothly propelled along the spiral trajectory, avoiding local deposition or eddies, and ensuring that the crystal particles are uniformly suspended. Finally, the material that has been controlled in multiple stages is discharged through the discharge pipe 5, completing the entire conveying process.

[0039] Furthermore, to address the issue of large drop in the flow path under special conditions, a multi-stage series structure is formed by the first flow guide trough 2 and the inclined second flow guide trough 4. Combined with the expansion and buffering effect of the spherical first connecting pipe 1 and the second connecting pipe 6, the flow velocity impact caused by the single-stage drop can be effectively reduced. At the same time, the first flow baffle 12 and the second flow baffle 14 inside the eccentrically arranged first flow baffle 7 and second flow baffle 8 can buffer the kinetic energy of the material through dynamic contact, preventing the crystal particles from breaking due to high-speed impact on the tank wall or turbulence, and significantly improving the particle size uniformity of the nickel chloride crystallization product.

[0040] Compared to traditional rigid flow-blocking structures such as fixed baffles and grids, the first flow-blocking plate 12 and the second flow-blocking plate 14, which rotate around the first rotating shaft 11 and the second rotating shaft 13, can automatically adjust their rotation speed according to the material flow rate. When the flow rate increases, the rotation speed of the flow-blocking plate increases, and the flow-blocking intensity increases accordingly. Conversely, it weakens, thus achieving adaptive flow blocking for nickel chloride crystal materials with different flow rates and concentrations. This solves the problem that fixed structures cannot flexibly adapt to changes in working conditions.

[0041] The multi-stage flow-blocking assembly, consisting of the first flow-blocking shroud 7 and the second flow-blocking shroud 8, works synergistically with the spiral flow-guiding structure formed by the flow-guiding channel 9 and the flow-guiding block 10 to effectively suppress turbulence and flow velocity fluctuations of materials during the conveying process. This ensures that nickel chloride materials containing suspended crystal particles are always in a stable flow state, reduces the risk of impurities being mixed in due to local disturbances, and guarantees the purity of the crystalline materials.

[0042] Structural description: First connecting pipe 1: It is spherical and connects the first guide channel 2 and the second guide channel 4, serving as a transition.

The first flow-blocking plate 12 inside can rotate around the first rotating shaft 11. It can dynamically contact and buffer the kinetic energy of the material, suppress turbulence, and adaptively adjust the flow-blocking intensity. The second flow-blocking shroud 8 is a cylindrical shell that is fixed to the eccentric position at the upper end of the second flow-guiding channel 4. The second flow-blocking plate 14 inside can rotate around the second rotating shaft 13 to achieve secondary flow blocking, further reduce the flow rate and stabilize the material flow state. The second connecting pipe 6 is spherical and located in the middle of the first guide channel 2. It is used to divert part of the material and reduce the local flow velocity by utilizing the volume expansion effect to avoid the concentrated impact of material causing crystal breakage. Guide channel 9: Spirally formed on the inner wall of the second guide channel 4, it guides the material flow by extending the flow distance and avoids local eddies and sedimentation; Guide block 10: It is fixed in a spiral shape to the inner wall of the second guide channel 4, forming a lateral guiding force on the material, and working with the guide channel 9 to make the material move smoothly along the spiral trajectory; First rotating shaft 11: provides rotational support for first flow-blocking plate 12, enabling the first flow-blocking plate 12 to rotate under material impact, thereby achieving dynamic flow blocking; First flow baffle 12: rotates around first rotating shaft 11 under material impact, buffers kinetic energy and suppresses turbulence through dynamic contact with the material, and adaptively adjusts flow baffle intensity according to flow rate changes; Second rotating shaft 13: provides rotational support for second flow-blocking plate 14, enabling second flow-blocking plate 14 to rotate under material impact, thereby achieving secondary dynamic flow blocking; Second baffle plate 14: Rotates around the second rotating shaft 13 under the impact of material, further buffering the kinetic energy of the material, reducing the flow velocity, and stabilizing the flow state; Feed pipe 3: Connected to the upper end of the first guide channel 2, serving as the inlet for nickel chloride crystal material to enter the device, conveying the material into the first guide channel 2; Discharge pipe 5: Connected to the right side of the second guide channel 4, serving as the final material outlet and discharging the material that has undergone multi-stage regulation.
