Description

Technical Field

[0001] This utility model relates to the field of distillation equipment technology, and more specifically, to an improved distillation apparatus for separating organic matter in the production process of orthoesters. Background Technology

[0002] In the production of orthoesters, the organic matter separation system is a crucial step in ensuring product quality and purity. Distillation, as the primary separation technology, plays a vital role in this process, and commonly used separation methods are mainly based on the differences in boiling points between the components.

[0003] For example, Chinese patent CN219815323U proposes a new type of distillation equipment. This device moves the scraper up and down by activating the extension and retraction of the electric push rod, which can scrape off impurities on the inner wall of the distillation tank. However, during use, there is a drawback that the raw materials react slowly inside the distillation column, resulting in low working efficiency. Utility Model Content

[0013] Several stirring rods are installed on the rotating roller.

[0014] Furthermore, the above solution includes a circular body shape for the stirring rod to reduce the adhesion of impurities.

[0015] Furthermore, the above scheme is further improved by using a filter cylinder with filter holes on all four sides for the rotating roller, and the bottom end of the filter cylinder is connected to the drain pipe, so that the liquid is filtered through the filter cylinder first and then discharged through the drain pipe, thereby improving the purity of the collected liquid.

[0016] Furthermore, the above solution includes a scraper assembly installed on the stirring assembly that contacts the inner wall of the lower chamber to clean impurities from the inner wall of the lower chamber.

[0017] Furthermore, the above-described solution includes a plurality of support rods disposed on the stirring rod;

[0019] Furthermore, the cleaning assembly includes a lead screw that is vertically rotatably mounted in the upper cavity and a guide rod that is fixedly mounted.

[0020] The top of the lead screw extends to the outside of the distillation tank and is connected to a servo motor;

[0021] A limit block is installed at the bottom of the guide rod;

[0022] Furthermore, a movable ring is fitted around the lead screw and guide rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0035] See attached document Figure 1 As shown, an improved distillation apparatus for an organic matter separation system in a crude ester production process includes a distillation tank 1, which is equipped with a raw material pipe 11, a drain pipe 12, a steam pipe 13, and a slag discharge pipe 14. The distillation tank 1 has an upper chamber and a lower chamber. A cleaning component 2 is installed in the upper chamber to scrape off impurities adhering to the inner wall of the upper chamber, and a stirring component 3 is installed in the lower chamber to stir the raw material entering the lower chamber.

[0036] In practical use, the raw material liquid enters the lower chamber through the raw material pipe 11. With the action of the stirring component 3, the raw material liquid forms a dynamic liquid film flow rather than a static state, which increases the gas-liquid interface renewal frequency, promotes molecular diffusion, and thus accelerates the distillation efficiency. After distillation, the liquid is discharged through the drain pipe 12, and the vapor is discharged through the steam pipe 13. The steam pipe 13 is connected to the condenser to cool and purify the vapor. After distillation, water is injected into the distillation tank 1. Then, the cleaning component 2 is activated to scrape off the impurities adhering to the inner wall of the upper chamber, which are finally discharged through the slag discharge pipe 14.

[0037] Regarding the specific structure of the stirring component 3 in the above scheme, please refer to the appendix. Figure 1 As shown:

[0038] The stirring assembly 3 includes a rotating rod 31 that is horizontally rotatably disposed in the lower cavity and a rotating roller 32 that is vertically disposed in the lower cavity;

[0039] Among them, a main gear 33 is installed on the rotating rod 31, and a driven gear 34 that meshes with the main gear 33 is installed on the rotating roller 32 so that the rotating rod 31 rotates and the rotating roller 32 moves synchronously.

[0040] Among them, one end of the rotating rod 31 extends to the outside of the distillation tank 1 and is connected to the drive motor 35 so that the drive motor 35 operates to rotate the rotating rod 31, and the drive motor 35 provides driving force to the rotating rod 31.

[0041] In addition, several stirring rods 36 with a circular main body are installed on the rotating roller 32, so that during the implementation process, the drive motor 35 operates to rotate the rotating rod 31, and finally the stirring rods 36 carry out stirring action in the lower cavity.

[0042] Considering the functionality of the stirring component 3, therefore, refer to the appendix. Figure 4 and attached Figure 5 As shown:

[0043] The rotating roller 32 is a filter cylinder with filter holes on all four sides, and the bottom end of the filter cylinder is connected to the drain pipe 12 so that the liquid is filtered through the filter cylinder before being discharged through the drain pipe 12; this design can improve the purity of the collected liquid.

[0044] In addition, considering that there are also a small amount of impurities in the fluid inside the lower cavity, in order to clean the impurities from the lower cavity wall, the following steps are taken, referring to the attached document. Figure 6 As shown:

[0045] The stirring assembly 3 is equipped with a scraper assembly 4 that contacts the inner wall of the lower cavity. Specifically, the scraper assembly 4 includes several support rods 41 set on the stirring rod 36. The support rods 41 are divided into left and right groups, and each group is connected to a vertical plate 42 on its outer side. A rubber plate 43 that contacts the inner wall of the lower cavity is installed on the outer side of the vertical plate 42. With this design, the scraper assembly 4 can move with the stirring assembly 3, so that the rubber plate 43 continuously contacts the inner wall of the lower cavity, thereby scraping off the impurities attached to the inner wall of the lower cavity.

[0046] Regarding the specific structure of cleaning component 2 in the above scheme, please refer to the appendix. Figure 1 and attached Figure 2 As shown:

[0047] Cleaning component 2 includes a lead screw 21 that is vertically rotatably mounted in the upper cavity and a guide rod 22 that is fixedly mounted.

[0048] The top of the lead screw 21 extends to the outside of the distillation tank 1 and is connected to a servo motor 23 so that the servo motor can operate to make the lead screw 21 rotate.

[0049] Among them, a limiting block 24 for limiting the range of motion is installed at the bottom end of the guide rod 22;

[0050] Furthermore, a movable ring 25 is connected to the outside of the lead screw 21 and the guide rod 22 through a mating mechanism;

[0051] In addition, a rubber ring 26 is provided on the outside of the moving ring 25 to contact the inner wall of the upper cavity, so that the servo motor 23 operates, causing the lead screw 21 to rotate, and finally causing the moving ring 25 to move vertically along the direction of the guide rod 22, thereby allowing the rubber ring 26 to complete the scraping action of the impurities attached to the inner wall of the upper cavity.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
