[0001] This utility model relates to the field of glycerin storage technology, specifically to a safe storage device for refined glycerin. Background Technology

[0002] This utility model relates to the technical field of refined glycerin storage devices, which are specialized equipment for storing refined glycerin. Their main function is to provide safe, stable, and efficient glycerin storage conditions for industrial production and raw material supply. These devices typically possess corrosion resistance, high sealing capabilities, and temperature control to ensure that the chemical properties of the glycerin remain unchanged during storage, thereby maintaining its high purity and quality stability. Simultaneously, these devices are designed with convenient conveying and metering systems to meet the needs of different production stages and improve operational efficiency. The significance of refined glycerin storage devices lies in ensuring the safety and quality of glycerin storage while reducing losses during transportation and storage, laying the foundation for high-quality production of downstream products, and making them an indispensable and important piece of equipment in modern industry.

[0003] For example, a utility model entitled "A Multifunctional Glycerin Storage Tank" with publication number CN219770738U includes a storage tank body. Support legs are fixedly connected to both sides of the bottom end of the storage tank body. A support base plate is provided at the bottom end of the storage tank body. Fixed legs are fixedly connected to both sides of the top end of the support base plate. Hydraulic cylinders are fixedly connected inside the fixed legs. A sealing groove is fixedly connected to the middle position of the top end of the support base plate. A sealing tank cover is installed at the top end of the storage tank body. Cylinders are fixedly connected to both sides of the top end of the sealing tank cover. A drive motor is fixedly connected to the middle position of the top end of the sealing tank cover.

[0004] Existing technical solutions, due to their simple single-arm design and lack of internal flow-regulating structures, present technical problems such as difficulty in heat preservation during transportation, and significant impact on tank strength caused by the front and rear impacts of vehicles during transportation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a safe storage device for refined glycerin, which solves the technical problems of the lack of heat preservation and slow-flow structure in existing technical solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe storage device for refined glycerin, comprising a main tank and a tank cover, forming the main storage structure. A filling structure is installed on the tank cover, and a discharge structure is installed at the lower end of the main tank. An isolation and flow-slowing structure is fixedly installed inside the main tank. This structure reduces the impact force caused by fluid inertia during vehicle braking and starting, and prevents accidental combustion of refined glycerin during filling and discharging. A cryogenic preservation structure is fixedly installed outside the main tank to maintain its low temperature and prevent spontaneous combustion during long-distance transportation. A sensor detection unit is installed inside the main tank to facilitate monitoring of the liquid condition within the tank.

[0007] Preferably, the isolation and flow-slowing structure is a multi-layer flow-slowing component. Each layer of the flow-slowing component includes seven isolation chambers. The seven isolation chambers are regular hexagonal cross-section cylinders with closely spaced hexagonal planes. Circular flow-slowing orifices are opened on the adjacent walls of the seven isolation chambers. Flow-slowing orifices are also opened on the upper and lower walls of adjacent isolation chambers in the multi-layer flow-slowing component. The flow-slowing orifices are circular through holes. Through the multi-layer, multi-format isolation chamber structure, when the car brakes or moves, and during filling, the liquid needs to slowly pass through the flow-slowing orifices, which reduces the impact force and inertial load of the liquid to a certain extent, reduces internal energy, reduces the impact on the tank, and improves the overall strength of the equipment.

[0008] Preferably, the low-temperature holding structure includes a refrigeration unit, which is fixedly installed on the side wall of the main tank. The refrigeration unit is a compressor refrigeration device. The cold end of the refrigeration unit is provided with a cold pipe, which is spirally wound around the outer wall of the main tank. The refrigeration unit is fixedly installed on the side wall of the main tank. An outer shell is fitted around the cold pipe outside the main tank. An insulation sleeve is fixedly installed on the outer shell. By using the principle of compressor refrigeration, a conventional refrigeration unit is selected, with the cold end facing outward. An additional protective shell can be assumed. The cold pipe is wound around the outside of the main tank to form an outer layer of isolation and cooling, preventing the formation of internal heat accumulation and high temperature during long-distance transportation and storage, which could trigger chemical reactions or combustion.

[0009] Preferably, a buffer cover is provided between the main tank and the cryogenic holding structure. The buffer cover is filled with buffer oil and is fitted onto the main tank. An outer elastic pad, which is U-shaped, is fixedly installed inside the buffer cover. An inner elastic pad is fixedly installed outside the main tank and fitted onto the outer elastic pad. A rubber pad is fixedly installed between the main tank and the isolation and slow-flow structure. Through the inner damping buffer structure, the impact of external physical impacts on the tank is reduced, the impact of impacts generated during the internal liquid transportation process is reduced, and the impact resistance is improved.

[0010] Preferably, the sensor detection unit includes a temperature detection unit, a liquid level detection unit, and a pressure detection unit. The temperature detection unit is fixedly installed on the inner wall of the main tank to detect the internal side wall temperature, thereby inferring the operating status of the cooling pipe. If the side wall temperature is too high, it proves that the refrigeration unit has failed to achieve its intended performance, and the operator shall inspect and replace it. The liquid level detection unit is fixedly installed inside the main tank and coincides with the axis. When the liquid level is too high, the filling is stopped. The pressure detection unit is fixedly installed on the lower inner wall of the main tank. When the internal pressure increases abnormally, the operator can release the pressure in time to check the situation.

[0011] Preferably, the injection structure includes an injection pipe, which is fixedly installed on the upper end of the main tank. The injection pipe passes through the tank cover and is fixedly installed with a sealing cap. An upper solenoid valve is fixedly installed inside the injection pipe. The sealing cap is opened by opening the upper solenoid valve to inject refined glycerin.

[0012] Preferably, the discharge structure includes a discharge pipe, in which a centrifugal pump is fixedly installed. The input end of the centrifugal pump is connected to the lower wall of the main tank, and the output end of the centrifugal pump is connected to the outside of the main tank. A lower solenoid valve is provided on the output end of the centrifugal pump. The refined glycerin is discharged through the centrifugal pump and the lower solenoid valve. The centrifugal pump operates within a suitable range, which helps to improve the discharge speed.

[0013] Preferably, the lower wall of the main tank is fixedly equipped with vertical support legs, which consist of eight columns. The side wall of the main tank is fixedly equipped with horizontal support legs, which consist of four rectangular columns. The horizontal support legs are connected by reinforcing beams, which enables vertical storage, horizontal storage and horizontal transportation, improving the application scenario effect. Beneficial effects

[0014] This invention provides a safe storage device for refined glycerin. Through an isolation and slow-flow structure, it effectively reduces the inertial impact of fluid caused by vehicle braking or starting during transportation, lowering the risk to the tank. During filling and discharging, the slow-flow design prevents accidental combustion of the refined glycerin, significantly improving equipment safety. The low-temperature maintenance structure utilizes refrigeration technology with a refrigeration unit, employing spiral-wound cold pipes and a multi-layered insulation design to maintain a low-temperature environment, preventing spontaneous combustion or chemical reactions caused by temperature rises during transportation or storage, ensuring glycerin quality and storage safety. A multi-layered buffer device combined with rubber pads effectively absorbs external mechanical impacts and internal liquid inertial impacts, significantly improving the device's impact resistance and extending its service life. The sensor detection unit includes temperature, liquid level, and pressure detection, allowing for continuous monitoring of temperature, liquid level, and pressure changes within the tank, ensuring stable operation and providing timely warnings or appropriate measures in case of abnormalities, further improving efficiency and operational safety.

[0018] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Detailed description follows.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a safe storage device for refined glycerin, including a main tank 1 and a tank cover 2, forming the main storage structure. A filling structure is installed on the tank cover 2, and a discharge structure is installed at the lower end of the main tank 1. An isolation and flow-slowing structure is fixedly installed inside the main tank 1. This structure reduces the impact force caused by fluid inertia during vehicle braking and starting, and prevents accidental combustion of refined glycerin during filling and discharging. A low-temperature maintaining structure is fixedly installed outside the main tank 1 to maintain its low temperature and prevent spontaneous combustion during long-distance transportation. A sensor detection unit is installed inside the main tank 1 to facilitate monitoring of the liquid condition within the main tank 1.

[0020] In this embodiment, the isolation and slow-flow structure is further configured as a multi-layer slow-flow assembly. Each layer of the slow-flow assembly includes seven isolation chambers 3, which are hexagonal cross-section prisms. The hexagonal planes of the seven isolation chambers 3 are densely arranged, and circular slow-flow outlets are opened on the adjacent walls of the seven isolation chambers 3. Slow-flow outlets are opened on the upper and lower walls of the adjacent isolation chambers 3 of the multi-layer slow-flow assembly. The slow-flow outlets are circular through holes. Through the multi-layer and multi-format isolation chamber 3 structure, when the car brakes or moves, and during filling, the liquid needs to slowly pass through the slow-flow outlets, which reduces the impact force and inertial load of the liquid to a certain extent, reduces internal energy, reduces the impact on the tank, and improves the overall strength of the equipment.

[0021] This embodiment further configures the cryogenic holding structure to include a refrigeration unit 4, which is fixedly installed on the side wall of the main tank 1. The refrigeration unit 4 is a compressor refrigeration device. The cold end of the refrigeration unit 4 is provided with a cold pipe 5, which is spirally wound around the outer wall of the main tank 1. The refrigeration unit 4 is fixedly installed on the side wall of the main tank 1. An outer shell 6 is fitted around the cold pipe 5 outside the main tank 1. An insulation sleeve 7 is fixedly installed on the outer shell 6. By using the principle of compressor refrigeration, a conventional refrigeration unit 4 is selected, with the cold end facing outward. An additional protective shell can be assumed. The cold pipe 5 is wound around the outside of the main tank 1 to form an outer layer of isolation and cooling, preventing the formation of internal heat accumulation and high temperature during long-distance transportation and storage, which could trigger chemical reactions or combustion.

[0022] In this embodiment, a buffer cover 8 is further provided between the main tank 1 and the cryogenic holding structure. The buffer cover 8 is filled with buffer oil 9 and is fitted onto the outside of the main tank 1. An outer elastic pad 10 is fixedly installed inside the buffer cover 8. The outer elastic pad 10 is U-shaped. An inner elastic pad 11 is fixedly installed outside the main tank 1 and the outer elastic pad 10 is fitted onto the outside of the inner elastic pad 11. A rubber pad 12 is fixedly installed between the main tank 1 and the isolation and slow-flow structure. Through the inner damping buffer structure, the impact of external physical impact on the tank is reduced, the impact of the impact generated during the internal liquid transportation process is reduced, and the impact resistance is improved.

[0023] In this embodiment, the sensor detection unit is further configured to include a temperature detection unit 13, a liquid level detection unit 14, and a pressure detection unit 15. The temperature detection unit 13 is fixedly installed on the inner wall of the main tank 1 to detect the internal side wall temperature and thus infer the operating status of the cooling pipe 5. If the side wall temperature is too high, it proves that the refrigeration unit 4 has failed to achieve its intended performance, and the operator shall inspect and replace it. The liquid level detection unit 14 is fixedly installed inside the main tank 1 and coincides with the axis. When the liquid level is too high, the filling is stopped. The pressure detection unit 15 is fixedly installed on the lower inner wall of the main tank 1. When the internal pressure increases abnormally, the operator can release the pressure in time to check the situation.

[0024] In this embodiment, the injection structure is further configured to include an injection pipe 16, which is fixedly installed on the upper end of the main tank 1. The injection pipe passes through the tank cover 2 and is fixedly installed with a sealing cover 17. An upper solenoid valve 18 is fixedly installed inside the injection pipe. By opening the upper solenoid valve 18, the sealing cover 17 is opened to inject refined glycerin.

[0025] In this embodiment, the discharge structure is further configured to include a discharge pipe 19, in which a centrifugal pump 20 is fixedly installed. The input end of the centrifugal pump 20 is connected to the lower inner wall of the main tank 1, and the output end of the centrifugal pump 20 is connected to the outside of the main tank 1. A lower solenoid valve 21 is provided on the output end of the centrifugal pump 20. The refined glycerin is discharged through the centrifugal pump 20 and the lower solenoid valve 21. The operating speed of the centrifugal pump 20 is within a suitable range, which helps to improve the discharge speed.

[0026] In this embodiment, a vertical support leg 22 is fixedly installed on the lower wall of the main tank 1. The vertical support leg consists of eight columns. A horizontal support leg 23 is fixedly installed on the side wall of the main tank 1. The horizontal support leg 23 consists of four rectangular columns. A reinforcing beam 24 connects the horizontal support legs 23, which enables vertical storage, horizontal storage, and horizontal transportation, improving the application scenario effect.

[0027] Its detailed connection methods are well-known technologies in this field; such as Figure 1-2 As shown, place the equipment in a suitable location according to your needs, and you can choose between vertical or horizontal storage. If transportation is required, it can be adjusted to a horizontal position and secured to the transport vehicle; check the equipment's inlet, outlet, and sealing to ensure that all components are intact and undamaged; connect the equipment's refrigeration system, solenoid valves, and sensor monitoring system to the power supply to ensure that each system is operating normally.

[0028] Open the sealing cap 17 of the injection pipe 16, while ensuring the injection equipment is connected to the main tank 1; open the upper solenoid valve 18 inside the injection pipe 16 to inject refined glycerin into the main tank 1. During the injection process, the liquid level detection unit 14 monitors the liquid level in real time to prevent liquid overflow; when the liquid level detection unit 14 detects that the liquid has reached the specified height, the system will issue an alarm and automatically close the upper solenoid valve 18; after the injection is completed, close the sealing cap 17 of the injection pipe 16 to ensure overall sealing.

[0029] Start the refrigeration unit 4 to maintain the equipment at a low temperature through compressor cooling. Ensure the cooling pipe 5 is running; its operation can be monitored by the temperature detection unit 13. The outer casing 6 and insulation layer will further reduce the impact of heat conduction. The sensor detection unit will continuously monitor changes in temperature, pressure, and liquid level inside the equipment to ensure the storage environment meets safety requirements. During long-term storage, it is necessary to periodically check the equipment's sealing, the refrigeration unit's operating status, and sensor feedback information to prevent abnormal situations.

[0030] If transportation is required, the equipment will be adjusted to a horizontal position and secured using horizontal support legs 23 and reinforcing crossbeams 24. The outer buffer cover 8 reduces vibration and impact during transportation; the internal isolation and flow-slowing structure effectively reduces liquid impact caused by braking or starting the vehicle during transportation, preventing internal structural damage or safety hazards; the refrigeration unit 4 operates continuously during transportation, maintaining a safe low temperature to prevent spontaneous combustion or other risks caused by temperature increases during transit.

[0031] When discharge is required, connect the discharge pipe 19 to the output device, such as a storage tank or production equipment, and check the sealing of the connection. Start the centrifugal pump 20 in the discharge structure and open the lower solenoid valve 21 at the same time. The centrifugal pump 20 will discharge the refined glycerin from the main tank 1 at a certain speed. During the discharge process, the remaining liquid height can be observed through the liquid level detection unit 14, and the discharge can be ensured to be smooth through pressure detection.

[0032] Shutting down the equipment: After the discharge is completed, close the lower solenoid valve 21 of the discharge pipe 19 and stop the pump. Then check whether the outlet of the discharge pipe 19 is clean.

[0033] Cleaning and maintenance: After emptying the equipment, clean the main tank 1 and related components with appropriate cleaning agents and methods, and replace or repair damaged parts in a timely manner; when not in use, the equipment should be sealed and stored to ensure that the external environment is dry and clean, and avoid direct sunlight to extend the service life of the equipment.
