Technical Field

[0001] This utility model relates to the field of ethyl oleate preparation technology, and in particular to an ethyl oleate preparation device with adsorption function. Background Technology

[0002] Ethyl oleate is a common fatty acid ester, typically prepared by the esterification reaction of oleic acid and ethanol. It is widely used in pharmaceuticals, cosmetics, and as a solvent for oils and fats. Its preparation primarily involves the esterification reaction of oleic acid and ethanol under the action of a catalyst. The preparation of ethyl oleate usually involves equipment such as a reaction vessel, heating system, condenser, and separator.

[0003] In the prior art, some impurities are usually involved in the preparation process of ethyl oleate, especially after the esterification reaction. If the impurities inside the ethyl oleate are not removed in time, the color, odor and purity of the prepared ethyl oleate will be affected, which will greatly affect the quality of the finished ethyl oleate. Therefore, this application proposes an ethyl oleate preparation device with adsorption function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies in the preparation of ethyl oleate, which often involves the presence of impurities, especially after the esterification reaction. If these impurities are not removed in time, they will affect the color, odor, and purity of the prepared ethyl oleate, thus significantly impacting the quality of the final product. Therefore, this invention proposes an ethyl oleate preparation device with adsorption function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An apparatus for preparing ethyl oleate with adsorption function includes a reaction vessel and an adsorption box. The top of the adsorption box has a feeding port, and the bottom of the reaction vessel is fixedly connected to a liquid outlet pipe. The apparatus also includes:

[0007] A connecting pipe, the bottom end of which is fixedly connected to the liquid outlet pipe, and the top end of which is fixedly connected to the top of the adsorption box, and a water pump is fixedly installed on the connecting pipe;

[0008] An infusion tube, the top end of which is fixedly connected to the bottom end of the adsorption box, and a valve is fixedly installed on the infusion tube;

[0009] A purification box, wherein the left side of the purification box is fixedly connected to the right end of the infusion tube, and the right side of the purification box is fixedly connected to the drain tube.

[0010] An activated carbon filter screen, the bottom end of which penetrates through the top of the purification chamber and extends into the interior of the purification chamber;

[0011] A sealing plate is placed on top of the purification chamber and mates with the top of the activated carbon filter.

[0012] The mounting assembly is located on the top of the purification chamber and cooperates with the sealing plate.

[0013] As a preferred embodiment of this utility model, an installation hole is provided on the top inner wall of the purification box, and the bottom end of the activated carbon filter passes through the installation hole and is slidably connected to the inner wall of the installation hole.

[0014] In a preferred embodiment of this utility model, a rubber ring is fixedly installed at the bottom of the sealing plate, and the bottom of the rubber ring is in contact with the top of the purification box.

[0015] As a preferred embodiment of this utility model, positioning rods are fixedly installed on the front and rear sides of the sealing plate, and positioning sleeves are fixedly installed on the front and rear sides of the purification box. The bottom end of the positioning rod passes through the corresponding positioning sleeve and is slidably connected to the inner wall of the positioning sleeve.

[0016] As a preferred embodiment of this utility model, the installation assembly includes two screws, two nuts, a pressure plate, and a threaded sleeve. The bottom end of the left screw is rotatably connected to the top of the purification box. The nuts are threaded onto the corresponding screws. The two nuts are fixedly connected to the left and right sides of the pressure plate, respectively, with the bottom of the pressure plate engaging with the top of the sealing plate. The bottom end of the threaded sleeve is fixedly installed on the top of the purification box, and the bottom end of the right screw is threaded into the threaded sleeve.

[0017] In a preferred embodiment of this utility model, two elastic blocks are fixedly installed at the bottom of the pressure plate, and the bottom ends of the two elastic blocks are in contact with the top of the sealing plate.

[0018] Beneficial effects:

[0019] 1. After ethyl oleate is prepared in the reaction vessel, it is discharged through the outlet pipe. Then, the water pump is started and connected to the pipe to transport the ethyl oleate into the adsorption tank. At this time, an appropriate amount of adsorbent is added into the adsorption tank through the feed port. Here, the adsorbent adsorbs the moisture and impurities inside the ethyl oleate. Finally, the adsorbed ethyl oleate is discharged into the purification tank through the delivery pipe and undergoes a second adsorption treatment through the activated carbon filter. Finally, it is discharged through the drain pipe to the next process. This method can achieve efficient adsorption treatment during the preparation of ethyl oleate, ensuring the purity, color and odor of ethyl oleate, and guaranteeing the quality of the finished ethyl oleate product.

[0020] 2. By rotating the pressure plate, the right-side screw can be rotated to the top of the threaded sleeve. Then, by rotating both screws simultaneously and engaging the threaded connection between the screws and the two nuts, the two nuts and the pressure plate can be moved downwards, thereby pressing and fixing the sealing plate with the pressure plate. The screw-on connection between the right-side screw and the threaded sleeve ensures the stability of the pressure plate pressing the sealing plate. This method facilitates the disassembly and assembly of the activated carbon filter, making it easy to maintain the activated carbon filter.

[0021] This invention achieves efficient removal of impurities and moisture from ethyl oleate after esterification through a simple structure, avoiding impact on the color, odor, and purity of the prepared ethyl oleate, thus improving the quality of the finished product and demonstrating strong practicality.
