Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, specifically to a pharmaceutical raw material oil storage tank. Background Technology

[0002] In the pharmaceutical, food, and fine chemical industries, the storage stability of raw material oils (such as volatile oils from traditional Chinese medicine and pharmaceutical excipient oils) is crucial. These raw materials are extremely sensitive to temperature, requiring maintenance within specific process temperature ranges to prevent solidification or decomposition, while also avoiding localized overheating that could lead to oxidation and deterioration. Therefore, modern storage tanks are generally equipped with jacketed temperature control systems.

[0003] However, existing jacketed temperature-controlled storage tanks have several significant technical bottlenecks in practical applications. First, traditional jacketed systems rely solely on the circulation of external heat transfer medium. The heat transfer medium in the jacket is mostly in a laminar or natural convection state, resulting in low heat transfer efficiency and a significant temperature gradient easily forming in the vertical direction of the tank. This leads to uneven heating of the material in the inner tank, seriously affecting the uniformity of the quality of the crude oil.

[0004] Secondly, to achieve mixing, some equipment installs mechanical agitators inside the material. However, this not only increases the complexity of the tank structure and requires dynamic sealing, thus introducing the risk of leakage, but the sealing point between the agitator shaft and the tank body is also a potential source of contamination, failing to meet the high requirements of sterility and cleanliness in pharmaceutical production. Furthermore, mechanical agitation consumes a huge amount of energy in high-viscosity oils and is difficult to achieve uniform and gentle mixing throughout the entire tank area. Therefore, in-depth research was conducted to address these issues, leading to this case study. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical raw material oil storage tank, comprising an inner tank and an outer tank. The inner tank is mounted inside the outer tank via a bracket. A temperature controller is installed on the inner side of both the inner and outer tanks. The temperature controller comprises multiple fitted rings, each fitted ring having a convex rotating annular groove. An inductor winding wire is installed inside the convex rotating annular groove. A convex annular block is installed inside the convex rotating annular groove. Multiple ball grooves are formed on the convex rotating annular groove. A supporting ball is installed on the inner side of the ball groove. A repulsive arc magnet is installed on the convex ring block. Multiple angular arc blocks are installed on the convex ring block. A temperature control box is installed on the outer side of the outer tank. An electric heater is installed inside the temperature control box. Heating liquid is installed inside the temperature control box. A dredging pump is installed on the temperature control box and the outer tank. An L-shaped reflux pipe is installed on the outer tank and connected to the temperature control box. A feeding dredging pipe and a discharging dredging pipe are installed on the inner tank and the outer tank.

[0006] Preferably, temperature control sensors are installed on the inner sides of the outer tank and the inner tank respectively, and hydrophobic ventilation filters are installed on the feeding pipe and the unloading pipe.

[0007] Preferably, a central controller is installed on the outside of the outer tank, and the central controller is electrically connected to the temperature control sensor, the electric heater, the drainage pump and the inductor winding wire respectively.

[0008] Preferably, the inner wall of the inner tank is coated with a food-grade anti-corrosion coating, and the interlayer space between the outer tank and the inner tank is filled with heat-insulating material.

[0009] Preferably, an emergency vent pipe is provided at the bottom of the outer tank, and a solenoid valve is installed on the emergency vent pipe.

[0010] Preferably, there are multiple sets of rings, which are evenly distributed along the axial direction of the inner tank.

[0011] This utility model provides a pharmaceutical raw material oil storage tank. It offers the following advantages: First, by using a magnetically driven temperature controller to generate an upward rotating vortex within the jacket, it achieves efficient and dead-angle-free circulation of the heat transfer medium, completely eliminating the temperature gradient of traditional tanks and ensuring extremely uniform heating of the raw material oil, thus greatly improving product quality and stability. Second, this mixing method eliminates the need for a mechanical stirring shaft extending into the tank, fundamentally eliminating the risks of dynamic seal leakage and cleaning contamination, resulting in a safer and more hygienic structure that fully complies with GMP standards for pharmaceutical production. Third, the central controller enables coordinated intelligent control of electric heating, fluid circulation, and magnetic agitation, achieving precise, dynamic, and energy-efficient temperature regulation. Finally, the introduction of safety designs such as emergency venting significantly enhances the inherent safety of the equipment under extreme operating conditions. In summary, this equipment integrates efficient temperature uniformity, aseptic protection, intelligent control, and proactive safety, effectively addressing many pain points of existing technologies.

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0018] Please see Figure 1-3 In the pharmaceutical, food, and fine chemical industries, existing jacketed temperature-controlled storage tanks for storing pharmaceutical raw oils have significant drawbacks: First, the heat transfer medium inside the traditional jacket has poor fluidity, easily forming temperature gradients, leading to uneven heating of the raw oil and affecting its quality; second, the internal mechanical stirring device used to achieve material mixing poses a risk of dynamic seal leakage and has many cleaning dead zones, making it difficult to meet aseptic process requirements, while also consuming a lot of energy; third, the system lacks sufficient intelligence and lacks coordinated and precise control of heating, cooling, and fluid disturbance; fourth, under extreme fault conditions, the high-temperature heat transfer oil in the jacket cannot be quickly emptied, posing a safety hazard. Therefore, this application protects the pharmaceutical raw material oil storage tank. The liquid inside the temperature control box 11 is diverted to the bottom of the inner side of the outer tank 2 by the diversion pump 14. The liquid is then diverted back to the inner side of the temperature control box 11 by the L-shaped return pipe 15, which is higher than the liquid level. The liquid inside the temperature control box 11 is heated by the electric heater 12. The temperature range between the inner and outer tanks 2 is controlled by heating the liquid 13. The inductor winding 5 in the inner wall of the ring 3 is energized to generate magnetism. The magnetism drives the repulsive arc magnet 9 on the convex ring block 6. The magnetism drives the multiple angle arc blocks 10 to rotate stably. The convex ring block 6 drives the multiple angle arc blocks 10 on it to generate a rotating upward water flow. This creates a rotating upward effect on the water flow between the inner and outer tanks 2, thereby achieving a stable mixing effect. In summary, the heating fluid 13 is heated by an external temperature control box 11, and then pumped into the bottom of the jacket between the outer tank 2 and the inner tank 1 by a diversion pump 14. After the liquid level in the jacket rises, it automatically overflows back to the control box through an L-shaped return pipe 15, forming a continuous heat medium circulation loop, thereby providing a stable base temperature for the raw material oil in the inner tank 1. To achieve precise and uniform temperature field control within the jacket, the core of the system lies in its unique temperature controller: when the central controller receives signals from the temperature control sensors on the walls of the inner and outer tanks 2, it can energize the inductor winding 5 inside the ring 3, causing it to generate a rotating magnetic field. This magnetic field interacts with the repulsive arc magnet 9 on the convex ring block 6, driving the ring block to rotate with low resistance in the convex rotating ring groove 4 through the support ball 8, and driving the angled arc block 10 on it to rotate synchronously, continuously pushing the heating fluid 13 to generate a rotating upward vortex, completely avoiding local overheating or underheating, and achieving efficient and uniform heat exchange.

[0019] Furthermore, the supplementary processes and principles ensure the safety, hygiene, and intelligence of the equipment: the central controller can coordinate the management of the electric heater 12, the diversion pump 14, and the magnetic drive system based on preset programs, and can even be expanded to control the refrigeration unit to achieve bidirectional precise temperature control; the food-grade anti-corrosion coating on the inner tank 1 wall and the insulation material filling the interlayer together ensure the purity of the raw oil and reduce heat loss; in an emergency, the controller can activate the emergency drain pipe solenoid valve at the bottom to quickly drain the high-temperature liquid in the interlayer, forming the final safety guarantee, thus constituting a complete system integrating intelligent temperature control, efficient mixing, safety protection, and compliant cleaning.

[0020] 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.
