Description

Technical Field

[0001] The utility model relates to the technical field of dioxolane production, in particular to a dioxolane temporary storage device. Background Art

[0002] 1,3-Dioxolane is an organic compound with the chemical formula C3H6O2. It is a colorless, transparent liquid that is soluble in water, ethanol, ether, and acetone. It is an excellent organic solvent and is often used as a solvent for oils and fats, an extractant, an electrolytic solvent for lithium batteries, and a chlorine-based solvent stabilizer.

[0003] At present, after the reaction of dioxolane in the reaction vessel is completed, a series of subsequent processes such as distillation, rectification, dehydration, and concentration are required to prepare dioxolane with higher purity. However, in the chemical production process, the supply of reactants and the generation rate of products are affected by many factors and are prone to fluctuations. At this time, the liquid temporary storage tank can greatly reduce the impact of such fluctuations, play a buffering role, and make the reaction system run more smoothly.

[0004] After the reaction of dioxolane in the reactor is completed, it is transferred to a temporary storage box for storage through a suction pump. The storage temperature of dioxolane needs to be kept within a low range. When the temperature is high, it will convert from liquid to gas. If the staff does not store it, at the same time, if the external environment temperature is too high, it will also interfere with the temporary storage of dioxolane. Utility Model Content

[0008] This device can keep dioxolane in a lower temperature range during temporary storage in the temporary storage box, greatly reducing the probability of converting from liquid to gas. At the same time, if the ambient temperature is too high, it can effectively absorb heat to maintain the ambient temperature within a certain range without large fluctuations. Combined with a thermal insulation shell, it minimizes the impact of the external environment on the dioxolane inside the temporary storage box, and the temporary storage effect of dioxolane is good.

The input end of the air pump is connected to the suction shell whose main body is cylindrical. A plurality of suction holes connected to the input end of the air pump are arranged on the circumference of the suction shell. The output end of the air pump is connected to the second water tank.

[0010] The above solution can minimize the impact of the surrounding high temperature environment on the dioxolane in the temporary storage box through the heat extraction component and the thermal insulation shell.

[0011] Furthermore, a cooler is provided in the second water tank.

[0012] The above solution cools the water in the second water tank by means of a cooler.

The input end of the air pump 31 is connected to the suction shell 32 whose main body is cylindrical. A plurality of suction holes 33 connected to the input end of the air pump 31 are arranged on the circumference of the suction shell 32.

[0025] The workflow of this utility model:

[0026] First, the dioxolane after the reaction in the reactor is injected into the temporary storage box 11 through a suction pump. During the initial installation, a heat-insulating shell 12 is provided on the outside of the temporary storage box 11. The heat-insulating shell 12 can effectively reduce the impact of external high temperature on the storage process of the dioxolane, and at the same time cooperate with the heat suction component to maintain the ambient temperature within a certain range without large fluctuations. While the heat is being insulated, the delivery pump 21 works to inject the water in the first water tank 22 into the cavity inside the water-cooling chamber 13, and then the dioxolane inside the temporary storage box 11 can be cooled, and the temperature is transferred to the water-cooling liquid. When the temperature of the dioxolane inside the temporary storage box 11 After the temperature drops to a value range pre-set in the controller, the first temperature sensor 15 immediately feeds back a signal to the controller, and the controller immediately stops water cooling. During the water cooling process, the heated water source can be promptly extracted through the output pump 23, and then injected into the heat exchanger 24 for cooling. After cooling, it can be recycled again into the first water tank 22. In this way, the dynamic flow of the water-cooling liquid can be achieved, thereby achieving a better cooling effect on the dioxolane in the temporary storage box 11. When the dioxolane is needed later, the controller immediately controls the transfer pump 14 to work to achieve automatic transfer of the dioxolane, and then other processing and preparation processes can be carried out;

At the same time, if the ambient temperature is too high, the heat can be effectively absorbed to maintain the ambient temperature within a certain range without large fluctuations. In combination with the thermal insulation shell 12, the influence of the external environment on the dioxolane inside the temporary storage box 11 is minimized, and the temporary storage effect of the dioxolane is good.

[0028] In some embodiments, a stirring assembly is provided in the temporary storage box 11, and the stirring assembly includes a motor, a rotating shaft, a stirring rod, etc.; this embodiment is not shown in the figure; the stirring assembly can reduce the probability of the substance in the dioxolane precipitating at the bottom of the temporary storage box 11, and the subsequent transfer and discharge is more thorough.
