Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical production equipment, specifically relating to a large-scale oil-water separation pharmaceutical production equipment. Background Technology

[0002] Chondroitin sulfate, as an important pharmaceutical raw material, faces numerous technical challenges in its production. This is particularly true for bovine chondroitin sulfate production, where the raw material gas conduit contains a large amount of oil, making traditional oil-water separation processes insufficient to meet pharmaceutical production requirements. Existing equipment has significant shortcomings in stirring efficiency, temperature control, and oil layer separation accuracy, resulting in product purity failing to meet pharmaceutical standards. Conventional stirring systems cannot effectively handle high-viscosity materials, uneven steam heating easily causes localized overheating, and the fixed depth of the oil extraction device is difficult to adapt to changes in the oil layer under different operating conditions. Furthermore, real-time monitoring methods during production are lacking, making precise control of key parameters impossible. These problems severely restrict the quality improvement and large-scale production of bovine chondroitin sulfate products. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] This invention provides a large-scale oil-water separation pharmaceutical production equipment to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A large-scale oil-water separation pharmaceutical production equipment includes a stainless steel tank with a cylindrical body and a conical bottom, the conical bottom having a discharge port; a high-torque stirring system including two motors driving a stirring shaft through a multi-stage speed change mechanism; a double-layer irregularly shaped stirring blade on the stirring shaft: the upper blade is perpendicular to the stirring shaft, and the lower blade forms an acute angle with the stirring shaft; a distributed steam system including multiple steam inlets located at the conical bottom of the tank and a tank jacket; a height-adjustable oil extractor that can dynamically adjust the oil extraction depth; and an online monitoring system including a temperature detection unit and a pH detection unit.

[0006] Furthermore, this application also proposes that in the double-layer irregularly shaped impeller, the upper impeller blade is an inclined flat plate type, the bottom impeller blade is an angled impeller type, and the two layers of impeller blades are arranged in a spatially staggered manner.

[0007] Furthermore, this application also proposes that a baffle plate be provided on the inner wall of the tank, and the installation direction is consistent with the flow direction of the liquid.

[0008] Furthermore, this application also proposes that the oil pumping unit is equipped with a real-time height adjustment mechanism to achieve dynamic control of the oil pumping depth.

[0009] Furthermore, this application also proposes that the pH detection unit of the online monitoring system includes a sleeve structure with a bottom groove.

[0010] Furthermore, this application also proposes a split pneumatic can lid, comprising two independently driven lids and a three-state control switch.

[0011] Furthermore, this application also proposes that a high-pressure sealing valve be installed at the discharge port and fastened with bolts.

[0012] Furthermore, this application also proposes that the tank body interlayer is provided with an insulation layer and symmetrically distributed sewage outlets.

[0013] Furthermore, this application also proposes that it includes a self-cleaning system comprising a spray pipe and a multi-angle spray ball located on the top of the tank.

[0014] Furthermore, this application also proposes that the transmission mechanism of the stirring system includes a multi-stage belt linkage device for the motor wheel and the reduction wheel.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. This solution enhances shear strength through dynamic superposition design, optimizes heat transfer efficiency through multi-dimensional steam distribution, and achieves precise oil extraction control through dynamic monitoring. It effectively solves the separation problem of high-oil feedstocks, significantly improves oil-water two-phase separation efficiency, and reduces residual oil in the finished product. The composite stirring mode ensures thorough emulsification of materials, the gradient heating system promotes phase separation, the dynamic oil extraction mechanism improves oil recovery rate, and the online monitoring system ensures the stability of process parameters, providing reliable equipment support for the large-scale production of bovine chondroitin sulfate.

[0017] 2. Through the combined design of irregularly shaped blades, a multi-directional composite flow field is formed within the tank's interlayer. The spatially staggered arrangement allows for the stepwise transfer of stirring energy, significantly improving the aggregation rate of oil particles and the formation rate of the separation interface. This effectively solves the technical problem of incomplete oil-water separation in the production of bovine chondroitin sodium. The synergistic effect of the directional flow guidance of the inclined flat blades and the shearing action of the angled blades, combined with the composite flow field formed by the spatially staggered arrangement, systematically improves the oil separation efficiency while avoiding secondary emulsification during the separation process.

[0018] 3. By using a directional baffle plate in the tank jacket, the fluid boundary layer maintains continuous flow, effectively reducing energy loss and preventing the separated oil layer from being re-dispersed. This solves the problem of low oil-water separation efficiency caused by the high oil content of bovine feedstock. The directional flow-guiding structure ensures that the oil droplet coalescence process is not disturbed by turbulence, allowing the separated oil layer to quickly float to the working area of ​​the pumping unit tank jacket, significantly improving oil recovery rate and the stability of the separation process.

[0019] 4. This solution achieves precise oil extraction under continuous operating conditions by dynamically tracking the oil layer interface, avoiding oil-water mixing contamination. This application solves the problem of difficult separation of bovine raw material oil by adjusting the extraction depth in real time to ensure that only the surface oil layer is extracted, preventing the mixing of raw materials and liquids that would lead to a decline in product quality, while ensuring the continuity of the production process.

[0020] 5. During the oil-water separation process, the double-layered irregularly shaped blades in the mixing system tank jacket continuously agitate the material, resulting in a laminar flow distribution of oil and water in the bottom region of the mixture. The pH detection unit tank jacket, through a slotted sleeve structure at the bottom, ensures that the detection probe only contacts the flowing liquid phase, preventing oil adhesion or solid impurities from interfering with the detection signal. The slotting direction of the sleeve structure is consistent with the flow direction of the liquid, further reducing fluid resistance.

[0021] Through the above technical solution, this application solves the problem of easy contamination of the tank jacket of the pH detection unit during the oil-water separation process, improves the accuracy of the detection data, and thus provides a reliable basis for precise control of reaction conditions, ultimately ensuring the efficiency of oil-water separation and product quality.

[0022] 6. During the production of bovine chondroitin sodium, when raw materials need to be added or equipment maintenance is required, a three-state control switch can be used to select a half-open mode, opening only one cover to prevent complete exposure of the tank and the entry of external contaminants. The two independently driven covers can achieve asymmetrical opening and closing. For example, during the oil-water separation stage, one cover can be kept fully closed to maintain stable internal pressure, while the other cover's opening is finely adjusted to coordinate with the oil extraction tank's interlayer operation. The pneumatic actuator uses closed-loop control, dynamically adjusting the cover's opening and closing status based on pH and temperature data fed back from the online monitoring system.

[0023] Through the above technical solution, this application achieves precise matching between the opening and closing action of the tank cover and tank body sandwich structure and the production process. While maintaining the sealing performance of the oil-water separation process, it improves operational flexibility, effectively reduces the mixing of external impurities during the raw material gas pipe processing, and ensures the purity of the separated liquid. The split structure also reduces the difficulty of equipment maintenance, and maintenance of a single cover does not require a complete shutdown of production.

[0024] 7. By combining the elastic sealing structure of the high-pressure sealing valve tank jacket with the detachable bolt fastening feature, the high-pressure sealing requirements of the separation process are guaranteed, while modular maintenance of key components is also achieved. This effectively solves the leakage problem at the discharge port caused by excessive oil content in the production of bovine chondroitin, avoids the loss of oil-water mixture and the resulting decrease in separation efficiency, and ensures the operational stability of the production equipment under high pressure, providing reliable infrastructure support for continuous production.

[0029] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] Furthermore, it should be understood in the description of this utility model that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Those skilled in the art will understand that, in the prior art, the production process of bovine chondroitin sulfate requires the processing of raw materials with high oil content, and traditional equipment struggles to achieve sufficient oil-water separation. Conventional stirring systems cannot handle high-viscosity materials, steam heating suffers from uneven temperature distribution, and static oil extraction devices cannot adapt to the dynamic changes in the stratification interface, resulting in high oil residue levels and affecting the stability of the final product quality.

[0035] To address these issues, the research and development process revealed that high oil-oil separation efficiency is limited by mixing uniformity, temperature control precision, and oil layer positioning capability. By analyzing material flow characteristics, a combined approach of enhancing shearing action and layered control was proposed. For high torque requirements, a dual-power synergistic drive scheme was adopted; to optimize the phase separation process, a multi-dimensional steam distribution pattern was designed; and a dynamic oil extraction control mechanism was constructed based on real-time monitoring data.

[0036] Therefore, this application proposes a production equipment including a stainless steel tank 11, which has a cylindrical body and a conical bottom, with a discharge port at the conical bottom; a high-torque stirring system 2, including two motors 21 driving a stirring shaft 23 through a multi-stage speed change mechanism, the stirring shaft 23 being equipped with double-layer irregularly shaped stirring blades, wherein the upper blades are perpendicular to the stirring shaft 23 and the lower blades form an acute angle with the stirring shaft 23; a distributed steam system, including multiple steam inlets 31 at the conical bottom of the tank 1 and a tank jacket 32; a height-adjustable oil extractor 4; and an integrated online monitoring system, including a temperature detection unit 51 and a pH detection unit 52.

[0037] The high-torque stirring system 2 refers to the use of two independent motors 21 connected by a gearbox or pulley system to form a superimposed power. Specifically, it can be achieved by combining an asynchronous motor 21 and a servo motor 21. The output torque is adjusted through a multi-stage speed change mechanism to adapt to the stirring requirements of materials with different viscosities. In the double-layer irregularly shaped stirring paddle, the upper blades are perpendicular to the stirring shaft 23 to generate radial flow, while the lower sharp-angled blades generate axial flow, forming a composite flow pattern. The distributed steam system achieves uniform heat conduction by setting an annular steam pipe at the conical bottom, with steam inlets 31 evenly distributed circumferentially, and a spiral guide plate installed in the tank jacket 32. The height-adjustable oil pump 4 uses a lifting mechanism driven by a servo motor 21, and achieves real-time tracking of the oil layer interface by feeding back position signals through an encoder. The temperature detection unit 51 of the online monitoring system uses a multi-point thermocouple matrix arrangement, and the pH detection unit 52 uses corrosion-resistant electrodes for online sampling.

[0038] Specifically, the cylindrical tank 1 promotes material settling through its conical bottom, while the dual-motor drive system 21 provides high torque output at low speeds, effectively breaking up oil agglomerates. Upper vertical blades generate horizontal vortices, while lower inclined blades create rising fluid, resulting in a three-dimensional mixing effect through double-layer stirring. The conical bottom steam inlet 31 directly acts on the sedimenting phase, and steam in the tank jacket 32 ​​maintains the overall temperature gradient. The pump 4 adjusts the suction depth based on online monitoring data, and temperature sensors and pH electrodes provide real-time feedback of process parameters. During operation, the material is fully emulsified under the combined stirring action, the steam system precisely controls the phase change temperature, and after dynamic monitoring of the oil-water interface, the pump 4 positions itself at the optimal separation position for continuous extraction.

[0039] Compared with existing technologies, traditional single-motor stirring systems are prone to insufficient power when dealing with high-viscosity materials, resulting in uneven mixing; conventional steam heating methods suffer from localized overheating, affecting phase separation; and fixed oil extraction devices cannot adapt to real-time changes in the stratification interface, causing fluctuations in oil recovery rates. This solution enhances shear strength through a power superposition design, optimizes heat transfer efficiency through multi-dimensional steam distribution, and achieves precise oil extraction control through dynamic monitoring.

[0040] Through the above technical solutions, this application effectively solves the problem of separating high-oil raw materials, significantly improves the efficiency of oil-water two-phase separation, and reduces the amount of residual oil in the finished product. The compound stirring mode ensures full emulsification of materials, the gradient heating system promotes the phase separation process, the dynamic oil extraction mechanism improves the oil recovery rate, and the online monitoring system ensures the stability of process parameters, providing reliable equipment support for the large-scale production of bovine chondroitin sulfate.

[0041] This application further proposes a double-layer irregularly shaped impeller in which the upper impeller 24 is an inclined flat plate and the bottom impeller 25 is an angled impeller, with the two layers of impellers arranged in a spatially staggered manner.

[0042] Among them, the inclined flat blade refers to a stirring component with a planar structure, whose mounting plane forms a non-perpendicular angle with the axis of the stirring shaft 23. Specifically, it can be welded from 5-8mm thick 304 stainless steel plate, and the material flow direction is controlled by changing the blade's tilt angle. The angled blade refers to a stirring component with a curved surface, whose blade tip forms a 30-60 degree angle with the axis of the stirring shaft 23. Specifically, it can be made from stamped 316L stainless steel plate, and the curved blade design enhances shear force. The spatially staggered arrangement means that the two layers of blades are not on the same plane in both the axial and circumferential directions. Specifically, this can be achieved by installing them with a 30-45 degree phase angle offset to avoid overlapping of the blade's movement trajectory.

[0043] Specifically, in the production of bovine chondroitin sodium, the oil-water separation of high-oil feedstock requires a specific flow field environment. Inclined flat-plate blades generate downward vortices during rotation, causing oil particles to aggregate downwards; angled blades generate radial shear flow at the bottom, disrupting the stability of the oil-water interface film. Because the two layers of blades are spatially misaligned, the axial flow generated by the upper blade and the radial flow from the lower blade create turbulence at their intersection, accelerating the collision and coalescence of oil particles while avoiding the flow field cancellation phenomenon caused by traditional coaxial blade arrangements.

[0044] Compared with existing technologies, conventional stirring devices use symmetrically distributed straight-plate impellers, resulting in a single vortex flow in the oil-water mixture and low separation efficiency. This solution, through the combined design of irregularly shaped impellers, creates a multi-directional composite flow field within the tank 1. The spatially staggered arrangement allows for a stepped transfer of stirring energy, significantly improving the aggregation rate of oil particles and the formation rate of the separation interface.

[0045] Through the above technical solution, this application effectively solves the technical problem of incomplete oil-water separation in the production of bovine chondroitin sodium. The synergistic effect of the inclined flat blade directional flow guidance and the oblique blade shearing action, combined with the composite flow field formed by the spatial misalignment arrangement, systematically improves the oil separation efficiency, while avoiding the secondary emulsification phenomenon formed during the separation process.

[0046] This application further proposes that the inner wall of the tank 1 is provided with a baffle 11, the installation direction of which is consistent with the flow direction of the liquid.

[0047] The baffle 11 is a plate-shaped flow-guiding structure fixed to the inner wall of the tank 1. It can be achieved by welding stainless steel plates or fixing with bolts, and its installation angle is parallel to the flow direction of the liquid generated by the stirring system 2. This structure reduces turbulent energy loss by adjusting the fluid trajectory. The liquid flow direction refers to the rotation direction of the material formed during the operation of the stirring system 2, which can be achieved by creating a spiral upward fluid pattern through the spatially staggered arrangement of double-layer irregularly shaped stirring paddles. The installation direction of the baffle 11 must be synchronized with the main fluid movement direction to avoid reverse impact.

[0048] Specifically, when the stirring system 2 drives the liquid to form a spiral flow, the baffles 11 are axially distributed along the inner wall of the tank 1, and their inclination angle matches the direction of the fluid motion vector formed by the stirring blades. During the rotation and ascent of the oil-water mixture, the baffles 11 continuously correct the fluid boundary layer motion state and suppress the swirling turbulence generated when the fluid contacts the tank wall. By controlling the consistency of the fluid motion trajectory, the oil phase substances are accelerated to accumulate under the action of centripetal force, forming a stable stratified interface.

[0049] Compared to existing technologies, traditional equipment lacks a flow guiding structure that matches the direction of the liquid flow. This results in irregular turbulence at the tank wall due to sudden changes in resistance, leading to secondary emulsification of oil droplets. This solution, through a directionally positioned baffle 11, maintains continuous flow in the fluid boundary layer, effectively reducing energy loss and preventing the separated oil layer from being re-dispersed.

[0050] Through the above technical solution, this application solves the problem of low oil-water separation efficiency caused by the high oil content of bovine raw materials. The directional flow guidance structure ensures that the oil droplet coalescence process is not disturbed by turbulence, and the separated oil layer can quickly float to the working area of ​​the oil pump 4, significantly improving the oil recovery rate and the stability of the separation process.

[0051] This application further proposes that the oil pump 4 be equipped with a real-time height adjustment mechanism to achieve dynamic control of the oil pumping depth.

[0052] The real-time height adjustment mechanism refers to a mechanical device that can instantly adjust the vertical position of the pumping unit 4. Specifically, it can be implemented using a lead screw drive driven by a stepper motor 21, which changes the suspension height of the pumping unit 4 by receiving control signals. The dynamic control of the pumping depth refers to adjusting the pumping position in real time according to changes in the oil layer interface. This can be achieved using a closed-loop control system linked to a level sensor and a controller, which generates adjustment commands by monitoring the height of the oil-water separation interface.

[0053] Specifically, during the oil-water separation process, as the thickness of the grease layer changes with the reaction state, the oil extractor 4 receives sensor signals through a real-time height adjustment mechanism, driving the lifting device to adjust the position of the oil extraction port. When the grease layer thickness decreases, the oil extractor 4 automatically rises to avoid extracting the lower layer of liquid; when the grease layer thickens, the oil extractor 4 synchronously descends to ensure sufficient extraction of the surface grease. The entire process is controlled in a closed loop by the controller, requiring no manual intervention.

[0054] Compared to existing technologies, traditional fixed oil pumping units require shutdown for repositioning, leading to reduced production efficiency, and manual judgment of oil layer thickness is prone to errors. This solution achieves precise oil pumping under continuous operation conditions by dynamically tracking the oil layer interface, avoiding oil-water mixing contamination.

[0055] Through the above technical solution, this application solves the problem of difficult separation of bovine raw oil. By adjusting the oil extraction depth in real time, it ensures that only the surface oil layer is extracted, preventing the mixing of raw materials and liquids that would lead to a decline in product quality, while also ensuring the continuity of the production process.

[0056] This application further proposes that the pH detection unit 52 of the online monitoring system includes a sleeve structure with a bottom groove.

[0057] The bottom-grooved sleeve structure refers to the tubular protective device that encloses the pH probe. Its bottom area has a groove, which can be made of corrosion-resistant stainless steel. The groove width can be set to millimeter-level gaps to allow the liquid to flow into the detection unit while preventing solid particles from entering. The groove at the bottom of the sleeve structure is positioned close to the bottom impeller 25 area of ​​the stirring system 2, ensuring that the detection unit directly contacts the dynamically mixed liquid environment.

[0058] Specifically, during the oil-water separation process, the double-layered irregularly shaped impellers of the stirring system 2 continuously agitate the material, resulting in a laminar flow distribution of oil and water in the bottom region of the mixture. The pH detection unit 52, through its bottom-grooved sleeve structure, ensures that the detection probe only contacts the flowing liquid phase, preventing oil adhesion or solid impurities from interfering with the detection signal. The groove direction of the sleeve structure is consistent with the flow direction of the liquid, further reducing fluid resistance.

[0059] Compared to existing technologies, traditional pH detection devices are directly exposed to the mixed solution, and the detection probe is easily coated with grease or blocked by solid particles, leading to distorted measurement data. This solution uses a bottom-grooved sleeve structure to form a physical isolation barrier while achieving real-time monitoring, ensuring the long-term stable operation of the detection unit.

[0060] Through the above technical solution, this application solves the problem that the pH detection unit 52 is easily contaminated during the oil-water separation process, improves the accuracy of the detection data, thereby providing a reliable basis for precise control of reaction conditions, and ultimately ensuring the oil-water separation efficiency and product quality.

[0061] This application further proposes a split-type pneumatic can lid 6, which includes two independently driven lids and a three-state control switch.

[0062] The split-type pneumatic can lid 6 refers to a can lid 6 divided into two independently operable lid bodies. This can be achieved using a pneumatic push rod and a separate hinge structure, with each lid body controlled by an independent power source for opening and closing. The three-state control switch refers to a control device with three states: fully open, half open, and fully closed. This can be achieved by using a solenoid valve and a pneumatic pressure sensor for linkage adjustment, controlling the range of motion of the lid body by switching the on / off state of the air passage.

[0063] Specifically, during the production of bovine chondroitin sodium, when raw materials need to be added or equipment maintenance is required, a three-state control switch can be used to select a half-open mode, opening only one cover to prevent complete exposure of the tank and the entry of external contaminants. The two independently driven covers can achieve asymmetrical opening and closing; for example, during the oil-water separation stage, one cover can be kept fully closed to maintain stable tank pressure, while the other cover's opening is finely adjusted to cooperate with the oil extractor 4. The pneumatic actuator uses closed-loop control, dynamically adjusting the cover's opening and closing status based on pH and temperature data fed back from the online monitoring system.

[0064] Compared to existing technologies, traditional can lids 6 are mostly integral structures, requiring complete exposure of the internal space of the can 1 when opened, which easily leads to grease oxidation and microbial contamination. The split design, however, allows for partial operation, reducing the risk of environmental interference. Conventional dual-state switches only support fully open or fully closed modes, failing to meet the process requirements of different stages in oil-water separation. Three-state control achieves precise regulation through an intermediate setting, avoiding energy waste caused by frequent switching.

[0065] Through the above technical solution, this application achieves precise matching between the opening and closing action of the can lid 6 and the production process, improving operational flexibility while maintaining the sealing performance of the oil-water separation process, effectively reducing the mixing of external impurities during the raw material gas pipe processing, and ensuring the purity of the separated liquid. The split structure also reduces the difficulty of equipment maintenance, and complete production shutdown is not required when inspecting a single lid.

[0066] This application further proposes installing a high-pressure sealing valve 71 at the discharge port, which is fastened with bolts.

[0067] Among them, the high-pressure sealing valve 71 refers to a sealing device capable of withstanding high-pressure conditions. Specifically, it can be implemented using a stainless steel gate valve with an elastic sealing ring. Its function is to prevent leakage of oil-water mixtures under high pressure. The bolted fastening connection refers to the rigid connection between components achieved through threaded fasteners. Specifically, it can be achieved using a flange and high-strength bolts in an assembly method. Its function is to ensure that the connection between the valve and the discharge port has pressure resistance stability and is easy to disassemble and maintain.

[0068] Specifically, in the oil-water separation process of pharmaceutical production, when material needs to be discharged from the discharge port at the conical bottom, the high-pressure sealing valve 71 forms a reliable sealing interface through pre-tightening force, preventing media leakage under high-pressure steam conditions. The bolted connection, through the planar contact of the flange and the axial tension of the bolts, forms a uniform sealing pressure distribution. In the production scenario of bovine chondroitin sulfate, this structure can cope with separation pressure fluctuations caused by high oil content in the gas pipeline feedstock, while also facilitating partial disassembly during equipment maintenance.

[0069] Compared to existing technologies, traditional equipment generally uses ordinary ball valves or butterfly valves for sealing, which are prone to sealing failure under high-pressure conditions, and welded connections cannot be used for local maintenance. This solution combines the elastic sealing structure of the high-pressure sealing valve 71 with the detachable characteristics of bolt fastening, ensuring both the high-pressure sealing requirements of the separation process and enabling modular maintenance of key components.

[0070] Through the above technical solution, this application effectively solves the problem of leakage at the discharge port caused by excessive oil content in the production process of bovine chondroitin, avoids the loss of oil-water mixture and the resulting decrease in separation efficiency, and at the same time ensures the operational stability of the production equipment under high pressure, providing reliable infrastructure support for continuous production.

[0071] This application further proposes that the tank interlayer 32 is provided with an insulation layer and symmetrically distributed sewage outlets.

[0072] The insulation layer refers to the heat-insulating structure covering the tank jacket 32, which can be implemented using polyurethane foam or rock wool filling. This reduces heat loss to maintain the temperature stability of the liquid inside the tank, ensuring the material remains within a suitable viscosity range during oil-water separation. The symmetrically distributed drain outlets are slag discharge channels symmetrically arranged on both sides of the bottom axis of the tank jacket 32. These can be connected to pipes via flange interfaces, balancing the discharge path of sediment within the tank jacket 32 ​​and preventing localized blockages or residue accumulation.

[0073] Specifically, the insulation layer wraps around the outside of the tank jacket 32, reducing heat loss to the external environment during steam heating, maintaining a uniform temperature of the liquid inside the tank, and promoting efficient separation of grease and liquid. Symmetrically distributed drain ports are located on both sides of the bottom of the tank jacket 32. During cleaning, valves can be opened simultaneously to discharge grease residue or dirt deposited in the tank jacket 32 ​​in a symmetrical direction, avoiding pressure imbalance or residue accumulation inside the tank jacket 32 ​​due to unilateral draining.

[0074] Compared to existing technologies, traditional tank jacket 32 ​​typically lacks insulation design, resulting in low steam heating efficiency and large temperature fluctuations. Furthermore, the drain outlets are often arranged on one side, making the tank jacket 32 ​​prone to blockage due to the single slag discharge path. This solution improves thermal energy utilization by adding an insulation layer and achieves uniform slag discharge through a symmetrical drain outlet design, significantly enhancing the stability of equipment operation.

[0075] Through the above technical solution, this application effectively solves the problem of material contamination caused by incomplete oil separation during the production of bovine chondroitin sulfate. By maintaining the temperature stability inside the tank, the probability of oil adhesion is reduced. At the same time, the symmetrical sewage discharge structure is used to improve the cleaning efficiency of the tank jacket 32, ensuring the long-term stable operation of the oil-water separation equipment.

[0076] This application further proposes that it also includes a self-cleaning system, comprising a spray pipe 8 located on the top of the tank and a multi-angle spray ball.

[0077] The spray pipe 8 refers to the liquid delivery pipe installed on the top of the tank 1. It can be made of stainless steel pipe with a branch interface structure, used to evenly distribute the cleaning medium to various areas inside the tank. The multi-angle spray ball refers to a spherical nozzle with multiple spray directions. It can be implemented using a hemispherical shell with nozzles at different tilt angles, used to expand the cleaning coverage. The combination of the spray pipe 8 and the spray ball solves the problem of oil residue on the inner wall of the tank 1 and the surface of the agitator components, avoiding cross-contamination caused by cleaning dead spots.

[0078] Specifically, the self-cleaning system activates after the oil-water separation process. Cleaning fluid is delivered to the top of tank 1 via spray pipe 8, where it is sprayed through multi-angle spray balls in different directions. The inclined nozzles on the spray balls ensure the water flow covers the inner wall of tank 1 and the surface of the agitator. The vertically downward water flow washes the conical bottom of tank 1, while the inclined water flow cleans the gap between the agitator shaft 23 and the baffle plate 11. This process removes grease and liquid residues adhering to the equipment surface without manual intervention.

[0079] In some specific embodiments, the spray pipes 8 can be arranged in a ring around the central axis of the tank top, and the nozzle angles of the spray balls can be set to different combinations of tilt angles between 30 degrees and 60 degrees. Quick-release interfaces can be configured at the connection points between the spray pipes 8 and the external water supply system to facilitate pipe separation during maintenance.

[0080] Compared with existing technologies, traditional oil-water separation equipment relies on manual high-pressure water jet washing or one-way spraying devices for cleaning, which results in low cleaning efficiency and repeated deposition of residues. This solution achieves full-coverage cleaning of the complex internal structure of the tank 1 through a three-dimensional spray pattern of multi-angle spray balls, and is particularly effective in removing stubborn grease deposits in the areas of the agitator and baffle 11.

[0081] Through the above technical solution, this application automatically completes the internal cleaning of the equipment during continuous production, avoiding downtime loss caused by manual cleaning, while eliminating the risk of oil residue contaminating subsequent production batches, and ensuring the purity and stability of bovine chondroitin sulfate products.

[0082] This application further proposes that the transmission mechanism of the stirring system 2 includes a multi-stage belt linkage device for the motor wheel and the reduction wheel.

[0083] The multi-stage belt linkage device refers to a phased power transmission structure composed of multiple pulleys and transmission belts. Specifically, it can be achieved by combining a three-stage V-belt pulley set with a trapezoidal tooth synchronous belt, adjusting the speed and torque output by progressively changing the transmission ratio. The motor pulley is the driving pulley directly connected to the output shaft of motor 21. Its diameter can be set to different sizes according to power requirements, such as a 150mm diameter cast iron wheel. The reduction pulley is the driven pulley connected to the input end of the reducer. Its diameter is larger than the motor pulley to achieve speed reduction and torque increase; for example, a 300mm diameter aluminum alloy wheel. Multi-stage linkage refers to two or more pulley sets connected in series to form a composite transmission path. This can be achieved by connecting motor 21 to the intermediate shaft and the intermediate shaft to the reducer, respectively.

[0084] Specifically, the transmission mechanism receives power from the dual motors 21 via the motor wheel, transmits it to the intermediate transition shaft via a first-stage belt, and then transmits the power to the input shaft of the reduction gear via a second-stage belt. This staged transmission method can achieve a high reduction ratio within a limited space, while the elastic deformation of the belt buffers impact loads. In the production process of bovine chondroitin, when the high-viscosity liquid causes a sudden change in stirring resistance, the flexibility of the belt drive system can automatically compensate for load fluctuations, avoiding mechanical damage to rigid transmission components due to overload.

[0085] Compared to existing technologies, traditional mixing equipment often uses single-stage gear reducers or direct-drive structures, which suffer from problems such as large size, difficult maintenance, or excessively high power transmission rigidity. In contrast, multi-stage belt-driven systems, through flexible transmission elements and graded reduction designs, achieve both flexibility and reliability in power transmission while maintaining a compact structure, making them particularly suitable for processing liquids containing high-viscosity oils.

[0086] Through the above technical solution, this application effectively solves the problem of unstable stirring power caused by excessive oil content in the production of bovine chondroitin, ensuring that the double-layer irregularly shaped stirring paddle continuously obtains balanced torque in viscous media, while reducing the maintenance frequency of the transmission system under high load conditions. This transmission structure, through a multi-stage buffer design, reduces the impact of sudden load changes on the motor 21, extending the service life of the equipment under continuous production conditions.
