Description

Technical Field

[0001] This utility model relates to the field of triacetylglycerol production technology, and specifically to a distillation and separation device for triacetylglycerol production. Background Technology

[0002] Triacetin is generally used as a fixative. It is a colorless, odorless, oily liquid, miscible with most organic solvents such as ethanol, ether, benzene, and chloroform, soluble in acetone, and insoluble in mineral oil. It is slightly soluble in water. At 25°C, its solubility in water is 5.9 g / 100 ml. It is soluble in alcohols, ethers, benzene, chloroform, and castor oil, but insoluble in linseed oil. It can dissolve nitrocellulose, cellulose acetate, acrylic resin, and polyvinyl acetate. It also has some solubility in natural rosin, but is immiscible with polyvinyl chloride, polystyrene, and chlorinated rubber. Distillation is a unit operation process that separates the entire mixture by evaporating the lower-boiling-point components due to their different boiling points, followed by condensation. It is a combination of evaporation and condensation unit operations.

[0003] A distillation apparatus for producing triacetylglycerol, disclosed in CN213049463U, exhibits the following defects during use:

[0004] This invention, when heating the raw liquid inside the distillation tank, uses a power source motor to drive a spiral lifting rod inside the mixing tube to rotate. The spiral lifting rod sucks up the raw liquid from the bottom of the distillation tank and discharges it from the top of the mixing tube, achieving circulation and mixing of the raw liquid inside the distillation tank. This results in more uniform and comprehensive heating of the raw liquid inside the distillation tank during the heating process, improving the accuracy of the distillation separation product. However, in actual use, the gas produced by the heated mixture may still contain some liquid, which enters the collection tank along with the gas, affecting the actual distillation separation effect of the device. Therefore, we propose a distillation separation device for the production of triacetylglycerol. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a distillation and separation device for the production of triacetylglycerol, which solves the problem that, during actual use, the gas generated by the heated mixture may still contain some liquid, which enters the collection tank along with the gas, affecting the actual distillation and separation effect of the device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A distillation and separation device for the production of triacetin includes a processing chamber with a through hole on the top surface. A fixed cover is fixedly installed on the top surface of the processing chamber. Several partitions are fixedly installed inside the fixed cover. The partitions are staggered on both sides of the inner wall of the fixed cover. A fixing hole is opened on the top surface of the fixed cover. A first connecting pipe with a U-shaped structure is fixedly installed inside the fixing hole.

[0008] Preferably, a fixing plate is fixedly installed on the outer wall of the processing box, and a first snap-fit ​​hole is opened on the top surface of the fixing plate. A condenser box is snapped into the inside of the first snap-fit ​​hole, and a second snap-fit ​​hole is opened on the top surface of the condenser box. The condenser box is fixedly installed together with the first connecting pipe through the second snap-fit ​​hole.

[0009] Preferably, the top surface of the condenser box has a connecting pipe, and the outer wall of the connecting pipe is fitted with a top cover.

[0010] Preferably, the bottom surface of the processing box has a through hole, a sealing ring is fixedly installed inside the through hole, a connecting seat is snapped into the through hole, a heat-conducting shell is fixedly installed on the top surface of the connecting seat, and a plurality of heating resistors are sleeved inside the heat-conducting shell.

[0011] Preferably, the outer wall of the heat-conducting shell is provided with a plurality of snap-fit ​​grooves, and a stirring blade is snapped into the inside of the snap-fit ​​grooves. A fixing box is fixedly installed on the bottom surface of the processing box, and a drive motor is sleeved inside the fixing box. The output end of the drive motor is fixedly installed together with the connecting seat.

[0012] Preferably, the outer wall of the processing box is provided with a second connecting pipe, the second connecting pipe is connected to the processing box, the outer wall of the second connecting pipe is provided with a through hole, and the outer wall of the second connecting pipe is provided with a shut-off valve, which is snapped onto the outer wall of the second connecting pipe through the through hole.

[0013] In summary, the present invention has the following main advantages:

[0014] 1. By setting up a baffle, the gas movement trajectory can be changed after the gas enters the fixed cover, increasing the duration of the gas inside the fixed cover. This allows the gas to come into contact with the baffle, and the moisture will remain on the outer wall of the baffle, thus achieving simple removal of moisture contained in the evaporated gas.

[0015] 2. By setting a heating resistor, the heat-conducting shell can be heated directly. Compared with bottom heating, it can ensure more uniform heating and avoid excessive temperature difference between the upper and lower liquids, which would affect the actual distillation efficiency. The design of the stirring blade can increase the stirring area and further ensure uniform heating of the internal liquid, thus ensuring the efficient operation of the device. The design of the drive motor can serve as the driving device, driving the internal stirring blade to rotate on its own. Attached Figure Description
