Description

Technical Field

[0001] The utility model belongs to the technical field of emulsification equipment, and particularly relates to an emulsification device. Background Art

[0002] When preparing chemical reagents, the emulsification process is often used. Emulsification is a phenomenon in which a liquid is evenly dispersed in another immiscible liquid in the form of extremely tiny droplets. Emulsification is a liquid-liquid interface phenomenon. Two immiscible liquids, such as oil and water, are separated into two layers in a container, with the oil with a lower density in the upper layer and the water with a higher density in the lower layer. If an appropriate surfactant is added and stirred vigorously, the oil is dispersed in the water to form an emulsion. This process is called emulsification.

[0003] Temperature has a great influence on the quality of emulsification, but there is no strict limit on the temperature. If both oil and water are liquid, emulsification can be achieved by stirring at room temperature. The general emulsification temperature depends on the melting point of the high-melting-point substances contained in the two phases, and factors such as the type of emulsifier and the solubility of the oil phase and the water phase must also be considered. In addition, the temperature of the two phases must be kept nearly the same, especially for wax and fat oil phase components with a higher melting point (above 70°C). When emulsifying, the low-temperature water phase cannot be added to prevent the wax and fat from crystallizing and precipitating before emulsification, resulting in blocky or rough and uneven emulsions. Generally speaking, when emulsifying, the temperature of both the oil and water phases can be controlled between 75°C and 85°C; the emulsification temperature sometimes also affects the size of the emulsion particles. For example, when using fatty acid soap anionic emulsifiers and the primary soap method for emulsification, when the emulsification temperature is controlled at 80°C, the size of the emulsion particles is about 1.8-2.0μm, so general emulsification processing equipment needs to be heated for emulsification.

[0004] In the above-mentioned high-temperature emulsification heating, cooling after heating is an important step in the emulsification process, which is conducive to promoting the mixing of the oil phase and the water phase and helping to form a more stable emulsified system. Generally, the cooling temperature is between 20-30°C, but most of the existing emulsification cooling is natural static cooling. For example, the Chinese medicine multi-enzyme emulsification method with publication number CN1174774C mentioned many times that natural static cooling is required after emulsification, but the time required for natural static cooling is too long, which seriously prolongs the emulsification process time and is not conducive to improving production efficiency.

[0035] In order to replenish the loss of cooling water, a water-filled pipe is provided on the heat storage tank 5 to form a water replenishment pipe 51.

[0036] In order to enable the heat storage tank 5 to store thermal energy, the heat storage tank 5 is covered with a heat-insulating cotton layer (the heat-insulating cotton layer is not shown in the figure).

[0037] Brief description of the usage process:

[0038] When in use, water is filled into the heat storage tank 5 through the water supply pipe 51, and the main liquid (such as conventional emulsified water+oil) is injected into the emulsification tank 1 from the first injection port 10 and the second injection port 11 respectively; auxiliary materials such as activators are added through the auxiliary material pipe 13, and then an external vacuum pumping device is connected through the vacuum pipe 12, and then the valves on the discharge pipe 3, the first injection port 10, the second injection port 11, and the auxiliary material pipe 13 are closed, and then the emulsification tank 1 is evacuated to a vacuum using the external vacuum pumping device, and then the valve on the vacuum pipe 12 is closed, and then the emulsification tank 1 is in a vacuum state.

[0039] The heater 7 is started again, and the heater 7 heats the water in the heat storage tank 5 to the temperature required for emulsification. The water pump 15 then pumps the heated water to the spiral tube 4. The spiral tube 4 and the tank wall of the emulsification tank 1 exchange heat to heat the water in the emulsification tank 1 to the temperature required for emulsification. The water in the spiral tube 4 after the temperature exchange enters the cold storage tank 6 for storage.

[0040] Then connect the motor 21 to a power source, the motor 21 is powered on and works, driving the stirring shaft 22 to rotate, and the stirring shaft 22 drives the emulsifying paddle 24 and the crushing paddle 25 thereon to rotate along, the emulsifying paddle 24 is used to stir and emulsify the water in the emulsification tank 1, and the crushing paddle 25 is used to crush the blocky or deposited incompletely emulsified structures in the water.

[0041] During the emulsification process, the cooling fan 8 is powered on and made to work, and the cooling fan 8 cools the water in the cold storage tank 6. When the emulsification is completed, the temperature in the cold storage tank 6 is also cooled (emulsification and cooling are carried out simultaneously); the finished product after emulsification is cooled, which helps to form a more stable emulsification system.

[0042] When cooling down, the water pump is started to reverse and the cold water in the cold storage tank 6 is pumped to the spiral tube 4. The water in the emulsification tank 1 is cooled to the set temperature through heat exchange with the tank wall of the emulsification tank 1. The water in the spiral tube 4 after the temperature exchange enters the heat storage tank 5 for storage. In this way, part of the heat after emulsification in the emulsification tank 1 is recovered by the spiral tube 4 to the heat storage tank 5. In the next emulsification process, less resources can be consumed to heat the water in the heat storage tank 5, thereby achieving the purpose of saving resources. At the same time, because the water in the heat storage tank 5 and the cold storage tank 6 is recycled, water resources are further saved. It is only necessary to regularly replenish the water consumed by evaporation into the heat storage tank 5 through the water replenishment pipe 51.

[0043] When the amount of heating water required by the emulsification tank 1 is large, the cooling fan 8 can be turned off, and the connecting valve 14 can be opened to discharge the water containing residual heat in the cold storage tank 6 directly into the heat storage tank 5 due to gravity, and then transported to the spiral tube 4 after being heated by the heater 7, and then discharged into the cold storage tank 6 after heat exchange; after the emulsified product in the emulsification tank 1 is cooled, the valve on the discharge pipe 3 is opened, and the water is discharged through the discharge pipe 3 and collected.
