Description

Technical Field

[0001] This utility model belongs to the field of glycerin delivery technology, specifically relating to a heat-stable glycerin dispensing 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℃, therefore it often needs to be stored at low temperatures. However, glycerin is usually required at room temperature or above room temperature for use. Therefore, glycerin often needs to be heated before use. However, glycerin has the characteristic of expanding when the temperature rises to around 60℃-80℃. Directly heating glycerin in the main fuel tank poses a danger. Furthermore, during use, excess glycerin often needs to be refluxed. If heated glycerin is directly refluxed into the main fuel tank, it will disrupt the temperature balance within the main fuel tank. Utility Model Content

[0004] The purpose of this invention is to provide a heat-stable glycerin dispensing system to solve the problems existing in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A thermally stable glycerin dispensing system includes a main oil tank, a circulating oil tank, and an oil-using device. A main oil delivery pipeline is provided between the main oil tank and the circulating oil tank, and a replenishment pump is installed on the main oil delivery pipeline. A circulating oil delivery pipeline and a circulating return pipeline are provided between the circulating oil tank and the oil-using device, and an oil supply pump is installed on the circulating oil delivery pipeline. A heater for heating glycerin and a partition are provided inside the circulating oil tank. The partition divides the interior of the circulating oil tank into two interconnected chambers at the top. A stirring oil passage for circulating glycerin between the two chambers is provided, and a stirring pump is installed on the stirring oil passage. An overflow pipeline is also connected between the main oil tank and the circulating oil tank.

[0007] Furthermore, an oil inlet is provided on the side wall of the main oil tank, a main oil inlet pipe is connected to the oil inlet, and a main oil pump is provided on the main oil inlet pipe.

[0008] Furthermore, a buoyancy switch is installed inside the main oil tank, which is used to control the start and stop of the main oil inlet pump.

[0009] Furthermore, a thermometer is installed inside the circulating oil tank, and the thermometer is electrically connected to a controller to collect the temperature of the glycerin inside the circulating oil tank; the controller is electrically connected to a heater and controls the heating power of the heater according to the temperature of the glycerin.

[0010] Furthermore, the replenishing pump is an additive pump; a liquid level sensor is also installed in the circulating oil tank; the additive pump is electrically connected to the controller, and the controller controls the additive pump according to the liquid level in the circulating oil tank.

[0011] Furthermore, the heater is an electric heater.

[0012] Furthermore, the circulating oil tank is installed at a higher position than the main oil tank.

[0013] Furthermore, the stirring pump is an electric stirring pump, the stirring blades of which extend into the circulating oil tank. The electric stirring pump is electrically connected to a controller, which controls the operating power of the electric stirring pump according to the glycerin temperature.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This solution uses a circulating oil tank to dispense glycerin from the main oil tank, and then heats the dispensed glycerin, which not only improves the heating efficiency of the glycerin, but also improves the safety of heating the glycerin.

[0016] 2. In this solution, an additive pump is installed between the circulating oil tank and the main oil tank. The liquid level sensor can monitor the liquid level in the circulating oil tank in real time and link it with the additive pump for control. Once the liquid level is lower than the set level, the additive pump can be started. The additive pump can add oil in small amounts and multiple times, which can effectively reduce the fluctuation of the overall oil temperature in the circulating oil tank caused by oil replenishment, thereby achieving the purpose of continuous and stable temperature control.

[0017] 3. The temperature sensor installed in the circulating oil tank can monitor the oil temperature in real time, which facilitates the control of parameters such as the heating power of the heater, the filling speed of the additive pump, and the stirring speed of the agitator pump.

[0018] 4. The stirring pump located at the bottom of the circulating oil tank can accelerate the mixing of glycerin in the circulating oil tank, thereby making the oil temperature more uniform throughout the circulating oil tank. Attached Figure Description

[0023] 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.

[0024] like Figure 1 As shown, this embodiment designs a thermally stable glycerin dispensing system, including a main oil tank 4, a circulating oil tank 6, and an oil dispensing device 10.

[0025] 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.

[0026] In this application, a main oil delivery pipeline 13 is provided between the main oil tank 4 and the circulating oil tank 6. A replenishment pump 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 by the replenishment pump. The replenishment pump is an additive pump 5, which meets the need for small-volume refueling. A liquid level sensor 11 is also provided in the circulating oil tank 6. The additive pump 5 is electrically connected to the controller, and the controller controls the additive pump 5 according to the liquid level in the circulating oil tank 6.

[0027] In this application, a circulating oil supply pipeline 14 and a circulating return pipeline 15 are provided between the circulating oil tank 6 and the oil-using device 10. An oil supply pump 9 is installed on the circulating oil supply pipeline 14. The circulating oil tank 6 is equipped with a heater 8 for heating glycerin and a partition 17. The partition 17 divides the interior of the circulating oil tank 6 into two interconnected chambers. A stirring oil passage for circulating glycerin between the two chambers is provided, and a stirring pump 12 is installed on the stirring oil passage. An overflow pipeline 16 is also connected between the main oil tank 4 and the circulating oil tank 6. The stirring pump 12 is electrically connected to a controller, which controls the operating power of the electric stirring pump 12 according to the glycerin temperature. The overflow pipeline 16 is used to return glycerin in the circulating oil tank 6 that exceeds the designed liquid level to the main oil tank 4.

[0028] In this application, a thermometer 7 is installed inside the circulating oil tank 6. The thermometer 7 is electrically connected to a controller and is used to collect the temperature of glycerin inside the circulating oil tank 6. The controller is electrically connected to a heater 8 and controls the heating power of the heater 8 according to the temperature of glycerin. The heater 8 can be an electric heater 8, thereby changing the amount of heat generated by controlling the current of the electric heater 8.

[0029] In this application, the installation position of the circulating oil tank 6 is higher than that of the main oil tank 4.

[0030] In this embodiment, the glycerin dispensing 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 the control of the main oil inlet pump 2 to replenish oil to the main oil tank 4 via the main oil inlet pipe 1. After the glycerin in the main oil tank 4 is pumped into the circulating oil tank 6 by the replenishment pump, it is heated by the heater 8 in the circulating oil tank 6. The replenishment pump can be a feed pump 5, which enables the addition of small amounts of glycerin, thus preventing excessive glycerin addition to the circulating oil tank 6 per unit time and affecting the stability of the oil temperature within the circulating oil tank 6. The real-time temperature of glycerin is measured by thermometer 7 in the circulating oil tank 6. Once the glycerin is heated to the specified temperature, it is pumped by oil supply pump 9 through circulating oil delivery pipeline 14 to oil consumption device 10. Simultaneously, the glycerin in oil consumption device 10 can be returned to the circulating oil tank 6 through circulating return pipeline 15, thereby stabilizing the oil pressure at oil consumption device 10. The stirring pump 12 in the circulating oil tank 6 can stir the glycerin, thereby ensuring a uniform oil temperature throughout the circulating oil tank 6.

[0031] In this embodiment, glycerin in the main oil tank 4 is dispensed into a circulating oil tank 6, and then the dispensed glycerin is heated. This not only improves the heating efficiency of the glycerin but also enhances safety during heating. Furthermore, a level sensor 11 monitors the level in the circulating oil tank 6 in real time and coordinates with the addition pump 5 for control. Once the level falls below the set level, the addition pump 5 is activated, replenishing the oil in small, frequent amounts, effectively reducing fluctuations in the overall oil temperature within the circulating oil tank 6 and achieving continuous and stable temperature control. A temperature sensor located in the circulating oil tank 6 monitors the internal oil temperature in real time, facilitating the control of parameters such as the heating power of the heater 8, the dispensing speed of the addition pump 5, and the stirring speed of the stirring pump 12. The stirring pump 12, located at the bottom of the circulating oil tank 6, accelerates the mixing of the glycerin in the circulating oil tank 6, resulting in a more uniform oil temperature throughout the tank.

[0032] 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.
