Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glycerin delivery technology, specifically relating to a glycerin heating and stabilization system. Background Technology
[0002] Glycerin, also known as glycerol, is an organic compound. It is a colorless, odorless, transparent, viscous liquid, mainly used as an organic chemical raw material, and can also be used as an analytical reagent and a lubricating laxative.
[0003] Glycerin has a boiling point of around 290°C, so it often needs to be stored at low temperatures. However, when using glycerin, it is often required to be at room temperature or above room temperature. Therefore, glycerin often needs to be heated before use. However, glycerin has the characteristic that it will start to expand when the temperature rises to around 60°C-80°C. Directly heating the glycerin in the main oil tank is dangerous. Utility Model Content

[0008] Furthermore, the circulating oil tank is installed at a higher position than the main oil tank.
[0009] Furthermore, an overflow port is provided on the upper side wall of the circulating oil tank. The overflow port is connected to one end of the overflow return oil pipe, and the other end of the overflow return oil pipe is connected to the top of the main oil tank.

[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.
[0021] like Figure 1 As shown, this embodiment designs a glycerol heating and stabilization system, including a main oil tank 4, a circulating oil tank 6, and an oil-using device 10.
[0022] The main oil tank 4 is located in the glycerin usage area and is typically installed in a low-lying location such as a basement, while ensuring it remains in a low-temperature environment. An oil inlet is located on the side wall of the main oil tank 4, connected to a main oil inlet pipe 1, on which a main oil pump 2 is installed. A buoyancy switch 3 is installed inside the main oil tank 4 to control the start and stop of the main oil pump 2. When the buoyancy switch 3 detects that the glycerin level in the main oil tank 4 is too low, it activates the main oil pump 2, drawing glycerin from another tank into the main oil tank 4 for storage. Conversely, when the buoyancy switch 3 detects that the glycerin level in the main oil tank 4 is too high, it shuts off the main oil pump 2, thus stopping the flow of glycerin from the main oil inlet pipe 1 to the main oil tank 4.
[0023] In this application, a main oil delivery pipeline 13 and an overflow return oil pipeline 12 are provided between the main oil tank 4 and the circulating oil tank 6. A replenishment pump 5 is provided on the main oil delivery pipeline 13. Glycerin in the main oil tank 4 is pumped to the circulating oil tank 6 through the main oil delivery pipeline 13 via the replenishment pump 5.
[0024] In this application, a thermometer 7 and a heater 8 are installed inside the circulating oil tank 6. The thermometer 7 is electrically connected to a controller and is used to collect the temperature of the glycerin inside the circulating oil tank 6. The heater 8 is used to heat the glycerin. The controller is electrically connected to the heater 8 and controls the heating power of the heater 8 according to the glycerin temperature. An overflow port is provided on the upper side wall of the circulating oil tank 6. The overflow port is connected to one end of the overflow return oil pipe 12, and the other end of the overflow return oil pipe 12 is connected to the top of the main oil tank 4. When the glycerin in the circulating oil tank 6 is heated and expands, the glycerin can flow back to the main oil tank 4 from the overflow return oil pipe 12. The installation position of the circulating oil tank 6 is higher than the installation position of the main oil tank 4, so that the glycerin can flow into the main oil tank 4 under the action of gravity, and thus no power device such as a pump is required on the overflow return oil pipe 12.
[0025] In this application, a circulating oil supply pipeline 14 is provided between the circulating oil tank 6 and the oil-using device 10, and a circulating oil pump 9 is provided on the circulating oil supply pipeline 14. The heated glycerin in the circulating oil tank 6 can be pumped by the circulating oil pump 9 through the circulating oil supply pipeline 14 to the oil-using device 10, so that the glycerin can be used at the oil-using device 10; a circulating return oil pipeline 11 is provided between the oil-using device 10 and the main oil tank 4.
[0026] In this application, the oil supply device 10 or the oil outlet of the circulating oil supply pipeline 14 is provided with an oil return port, which is connected to one end of the circulating oil return pipeline 11, and the other end of the circulating oil return pipeline 11 is connected to the top of the main oil tank 4. The installation position of the oil supply device 10 is higher than the installation position of the main oil tank 4, so that glycerin can flow into the main oil tank 4 under the action of gravity, and the circulating oil return pipeline 11 does not need to be equipped with a pump or other power device.
[0027] In this embodiment, the glycerin heating and stabilization system primarily stores glycerin at low temperatures in the main oil tank 4. This low temperature can be maintained by placing ice blocks around the main oil tank 4 or by using electric cooling. A buoyancy switch 3 installed in the main oil inlet pipe 1 detects the glycerin level, facilitating control of the main oil pump 2 to replenish the main oil tank 4. After the glycerin in the main oil tank 4 is pumped into the circulating oil tank 6 by the replenishment pump 5, it is heated by the heater 8 in the circulating oil tank 6. The heated glycerin expands and, exceeding the overflow port, flows back to the main oil tank 4 through the overflow return pipe 12. The thermometer 7 in the main oil tank 4 measures the real-time temperature of the glycerin. Once the glycerin reaches the designated temperature, the circulating oil pump 9 delivers it to the oil-using device 10 via the circulating oil delivery pipe 14. Simultaneously, the glycerin at the oil-using device 10 is returned to the main oil tank 4 via the circulating oil return pipe 11, thus stabilizing the oil pressure at the oil-using device 10.
[0028] In this embodiment, the main oil tank 4 is reheated after being partially filled with a small-capacity circulating oil tank 6. This not only improves the heating efficiency of glycerin but also enhances the safety of heating glycerin. At the same time, the overflow return oil pipe 12 and the circulating return oil pipe 11 can reflux the glycerin, thereby releasing the pressure when the glycerin expands and improving the safety of using glycerin.
[0029] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
