Description

Technical Field

[0001] This utility model relates to a high-efficiency stirred nitrate separation reactor for a salt and nitrate workshop. Background Technology

[0002] In salt and nitrate production workshops, the nitrate separation reactor is the core equipment for achieving salt and nitrate separation, and its cooling efficiency directly affects the quality of nitrate crystallization and production energy consumption. Traditional nitrate separation reactors generally adopt jacketed or coiled cooling structures, and the cooling medium (such as water or chilled liquid) flows through the heat exchange chamber in a static or low-flow-rate state.

[0003] Static or low-disturbance cooling can lead to local overheating or undercooling, resulting in uneven heat dissipation and failure to dissipate reaction heat in a timely manner. This affects the uniformity of nitrate crystal growth and particle size distribution, and reduces product purity. In view of this, this utility model proposes a high-efficiency stirred nitrate precipitation reactor for a salt and nitrate workshop to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency stirred nitrate reactor for a salt and nitrate workshop to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency stirred nitrate separation reactor for a salt and nitrate workshop includes a reaction tank, the reaction tank being provided with a heat dissipation sidewall, and a discharge pipe being provided at the bottom end of the reaction tank;

[0007] An annular sealing shell is provided on the heat dissipation sidewall, and a heat dissipation cavity is provided between the annular sealing shell and the heat dissipation sidewall. The annular sealing shell is provided with a sealing ring, which is sleeved at the discharge pipe. A rotating ring is sleeved on the outer wall of the sealing ring, and multiple sets of disturbance plates are provided on the rotating ring. The rotating ring rotates about the axis of the sealing ring, so that the multiple sets of disturbance plates are displaced in the heat dissipation cavity to disturb and accelerate heat dissipation.

[0008] As an improvement to the above technical solution, the outer wall of the sealing ring is provided with two sets of limiting rings, the two sets of limiting rings are symmetrically arranged, and the rotating ring is rotatably arranged between the two sets of limiting rings.

[0009] As an improvement to the above technical solution, the heat dissipation sidewall is provided with two sets of reinforcing rings, and the two sets of reinforcing rings are arranged symmetrically.

[0010] A connecting ring is provided between the multiple sets of disturbance plates, and the connecting ring is rotatably disposed between the two sets of reinforcing rings.

[0011] As an improvement to the above technical solution, a driving assembly is provided at the bottom of the annular sealing housing;

[0012] The rotating ring is provided with an external gear ring, which is coaxially arranged with the rotating ring. The drive component cooperates with the external gear ring, so that the rotating ring rotates around the axis of the sealing ring.

[0013] As an improvement to the above technical solution, the drive assembly includes a drive rod, which is rotatably mounted on an annular sealed housing. A drive gear and a drive wheel are respectively provided at both ends of the drive rod. The drive gear meshes with an external gear ring, and the drive wheel is connected to an external motor shaft via a belt.

[0014] As an improvement to the above technical solution, the side wall of the annular sealing shell is provided with multiple sets of liquid inlet pipes, which are connected to the heat dissipation cavity;

[0015] The bottom end of the annular sealed housing is provided with multiple sets of liquid outlet pipes, which are connected to the heat dissipation cavity.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting a rotatable disturbance plate to forcibly agitate the cooling liquid in the heat dissipation cavity, the liquid thermal boundary layer is effectively broken, the turbulence between the cooling liquid and the heat dissipation sidewall is enhanced, and the heat transfer coefficient is greatly improved. This significantly accelerates the heat removal efficiency of the material in the reaction tank. Furthermore, the forced convection effect of the disturbance plate can significantly improve the heat exchange rate of the cooling liquid. Under the premise of achieving the same cooling effect, the cooling liquid flow requirement can be reduced or the cooling time can be shortened, thereby reducing system energy consumption and improving energy utilization efficiency.

[0020] The efficient dynamic heat dissipation mechanism can accurately and quickly control the temperature of the material inside the reaction vessel, ensuring that the salt precipitation reaction takes place within the optimal temperature range. This effectively avoids problems such as uneven crystal growth and impurity encapsulation caused by local overheating or temperature fluctuations, thereby improving the purity and particle size uniformity of nitrate crystals.

[0033] 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.

[0034] Example:

[0035] like Figure 1-11As shown, this embodiment proposes a high-efficiency stirred nitrate separation reactor for a salt and nitrate workshop, including a reaction tank 10, the reaction tank 10 is provided with a heat dissipation sidewall 14, and the bottom end of the reaction tank 10 is provided with a discharge pipe 13.

[0036] An annular sealing shell 20 is provided on the heat dissipation sidewall 14. A heat dissipation cavity 21 is provided between the annular sealing shell 20 and the heat dissipation sidewall 14. A sealing ring 22 is provided on the annular sealing shell 20. The sealing ring 22 is sleeved on the discharge pipe 13. A rotating ring 30 is sleeved on the outer wall of the sealing ring 22. Multiple sets of disturbance plates 70 are provided on the rotating ring 30. The rotating ring 30 rotates about the axis of the sealing ring 22, so that the multiple sets of disturbance plates 70 are displaced in the heat dissipation cavity 21 to disturb and accelerate heat dissipation.

[0037] In this embodiment, when the nitrate precipitation process is carried out in the salt and nitrate workshop, the material is introduced into the reaction tank 10 for reaction processing, and at the same time, cooling liquid is introduced into the heat dissipation cavity 21 so that the cooling liquid comes into contact with the heat dissipation side wall 14. Then, the rotating ring 30 is controlled to rotate around the axis of the sealing ring 22, so that multiple sets of disturbance plates 70 are displaced in the heat dissipation cavity 21 to disturb the cooling liquid.

[0038] By setting a rotatable disturbance plate 70 to forcibly agitate the cooling liquid in the heat dissipation cavity 21, the liquid thermal boundary layer is effectively broken, the turbulence between the cooling liquid and the heat dissipation side wall 14 is enhanced, the heat transfer coefficient is greatly improved, and the heat removal efficiency of the material in the reaction tank 10 is significantly accelerated. In addition, the forced convection effect of the disturbance plate 70 can significantly improve the heat exchange rate of the cooling liquid. Under the premise of achieving the same cooling effect, the cooling liquid flow requirement can be reduced or the cooling time can be shortened, reducing system energy consumption and improving energy utilization efficiency.

[0039] The efficient dynamic heat dissipation mechanism can accurately and quickly control the material temperature inside the reaction vessel 10, ensuring that the salt precipitation reaction takes place within the optimal temperature range. This effectively avoids problems such as uneven crystal growth and impurity encapsulation caused by local overheating or temperature fluctuations, thereby improving the purity and particle size uniformity of nitrate crystals.

[0040] Specifically, the outer wall of the sealing ring 22 is provided with two sets of limiting rings 23, the two sets of limiting rings 23 are symmetrically arranged, and the rotating ring 30 is rotatably arranged between the two sets of limiting rings 23.

[0041] In this embodiment, the rotating ring 30 is axially clamped by two sets of symmetrically arranged limiting rings 23, which effectively restricts the displacement freedom of the rotating ring 30 along the axis of the sealing ring 22, ensuring that the rotating ring 30 always maintains a stable axial position during operation and preventing axial movement caused by vibration or load changes.

[0042] Specifically, the heat dissipation sidewall 14 is provided with two sets of reinforcing rings 17, and the two sets of reinforcing rings 17 are symmetrically arranged;

[0043] A connecting ring 50 is provided between the multiple sets of disturbance plates 70, and the connecting ring 50 is rotatably disposed between the two sets of reinforcing rings 17.

[0044] In this embodiment, two sets of symmetrically arranged reinforcing rings 17 are directly integrated into the heat dissipation sidewall 14 to form a high-strength annular support frame, providing a stable rotation reference for the connecting ring 50. This design significantly enhances the local deformation resistance of the heat dissipation sidewall 14, effectively resists the radial load and vibration impact generated during the operation of the rotating component, and ensures the mechanical stability of the overall structure during long-term operation.

[0045] Specifically, a drive assembly 60 is provided at the bottom of the annular sealing housing 20;

[0046] The rotating ring 30 is provided with an outer gear ring 40, which is coaxially arranged with the rotating ring 30. The drive assembly 60 cooperates with the outer gear ring 40, so that the rotating ring 30 rotates around the axis of the sealing ring 22.

[0047] In this embodiment, the outer gear ring 40 and the rotating ring 30 are coaxially integrated to ensure that the driving torque is evenly distributed along the circumference of the rotating ring 30. The driving component 60 acts directly on the outer gear ring 40 to form a rigid transmission chain, eliminating energy loss and motion lag in the intermediate transmission links, and realizing high-precision, low-vibration synchronous driving of the rotating ring 30.

[0048] Specifically, the drive assembly 60 includes a drive rod 62, which is rotatably mounted on the annular sealing housing 20. A drive gear 61 and a drive wheel 63 are respectively provided at both ends of the drive rod 62. The drive gear 61 meshes with the external gear ring 40, and the drive wheel 63 is connected to the external motor shaft via a belt.

[0049] In this embodiment, the drive rod 62 serves as the core transmission shaft, and integrates power input and output functions with the drive wheel 63 through the drive gears 61 at both ends. The drive gears 61 are rigidly meshed with the external gear ring 40, and the motor torque is transmitted to the rotating ring 30 without slippage.

[0050] The drive wheel 63 is connected to an external motor via belt drive, enabling a smooth transition from high-speed motor power to low-speed, high-torque operation. This design ensures that the disturbance system achieves the optimal speed to match fluid resistance.

[0051] Specifically, the side wall of the annular sealing housing 20 is provided with multiple sets of liquid inlet pipes 24, and the liquid inlet pipes 24 are connected to the heat dissipation cavity 21;

[0052] The bottom end of the annular sealing housing 20 is provided with multiple sets of liquid outlet pipes 25, which are connected to the heat dissipation cavity 21.

[0053] In this embodiment, the liquid inlet pipe 24 is used to introduce cooling liquid into the heat dissipation cavity 21, and the liquid outlet pipe 25 is used to export cooling liquid from the heat dissipation cavity 21.

[0054] Of course, the coolant is introduced into the inlet pipe 24 through the pump body, and the hot coolant can be transported to external cooling equipment (such as cooling towers and heat exchangers) for cooling. After cooling, it is pumped back into the inlet pipe 24 to form a complete closed-loop cooling cycle system.

[0055] By providing multiple sets of inlet pipes 24 on the sidewalls of the annular sealed housing 20 and multiple sets of outlet pipes 25 at the bottom, which are connected to the heat dissipation cavity 21, a forced circulation coolant passage is formed. This design enables the coolant to be continuously and controllably introduced into the heat dissipation cavity 21 from the inlet pipes 24, flow through the heat dissipation sidewall 14 for heat exchange, and then be efficiently discharged from the outlet pipes 25, completing a complete circulation process.

[0056] Specifically, the top of the reaction vessel 10 is provided with multiple sets of feed pipes 11;

[0057] The top of the reaction vessel 10 is provided with a stirring shaft 16, the stirring shaft 16 is provided with stirring blades 15, and the reaction vessel 10 is provided with a drive motor 12, which is connected to the stirring shaft 16 in a transmission manner.

[0058] In this embodiment, the feed pipe 11 facilitates the introduction of materials into the reaction tank 10. Of course, the drive motor 12 drives the stirring shaft 16 to rotate, which facilitates the stirring blades 15 to stir the materials, thereby improving the reaction efficiency.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
