Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of ethylene glycol butyl ether purification technology, and more specifically, to an ethylene glycol butyl ether purification apparatus. Background Technology

[0002] Ethylene glycol butyl ether is a colorless and transparent liquid with a mild odor. It has good solubility, is miscible with a variety of organic solvents, and also has a certain solubility in water. Ethylene glycol butyl ether is an important organic chemical raw material, widely used in coatings, inks, cleaning agents, and many other fields. However, during its production and storage, some impurities are often mixed in. These impurities affect the performance and quality of ethylene glycol butyl ether. Therefore, purification equipment is needed to purify ethylene glycol butyl ether to reduce the impurities it carries.

[0003] In existing technologies, ethylene glycol butyl ether purification devices typically employ distillation to purify ethylene glycol butyl ether. However, when the boiling points of impurities are close to those of ethylene glycol butyl ether, simple distillation is insufficient to achieve good separation results. Furthermore, the distillation process consumes a large amount of energy, leading to high energy costs. Utility Model Content

A driving component for driving the stirring shafts to rotate is provided inside the movable frame. Multiple stirring rods are mounted on the lower part of the outer side of the stirring shafts. The stirring rods rotate synchronously with the stirring shafts. The transmission wheel is sleeved on the stirring shaft and rotates synchronously with the stirring shaft. The two transmission wheels are connected by a belt drive.

[0007] The transmission mechanism includes a transmission plate, a U-shaped frame, and a transmission gear. The transmission plate is mounted on the upper side of the movable frame and moves synchronously with the movable frame.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0031] like Figures 1-5The illustration shows an ethylene glycol butyl ether purification apparatus according to an embodiment of this disclosure. It includes a processing chamber 1, a frame 2, a baffle 3, a feed pipe 4, a toothed plate 5, a moving frame 6, a stirring mechanism, and a transmission mechanism. Compared to existing technologies where simple distillation is insufficient to achieve good separation when the impurities and ethylene glycol butyl ether have similar boiling points, and where distillation consumes a large amount of energy leading to high energy costs, this embodiment achieves simultaneous purification of ethylene glycol butyl ether and the adsorbent through the cooperation of the frame 2, baffle 3, and feed pipe 4. The feed is purified by adsorption instead of distillation. The adsorption process is simple and easy to operate. It can be carried out at room temperature without the need for complex equipment and high-temperature conditions, thus reducing energy costs. It has a good effect on removing trace impurities and enhances the purification effect of ethylene glycol butyl ether. Through the cooperation of the moving frame 6, the stirring mechanism and the transmission mechanism, the uniform stirring of ethylene glycol butyl ether and the adsorbent in the stirring area is achieved, which enhances the adsorption effect of the adsorbent on impurities in ethylene glycol butyl ether and further improves the purification effect of ethylene glycol butyl ether.

[0032] like Figure 2 As shown, the frame 2 is set inside the processing box 1. The baffle 3 is inserted into one of the two sides of the processing box 1 and abuts against the inner wall of the frame 2. The space above the baffle 3 in the frame 2 forms a stirring zone. A sealing strip is installed on the lower side of the inner wall of the frame 2. The sealing strip is U-shaped. A U-shaped sealing groove is opened on the outer side of the baffle 3. The sealing strip can seal the frame 2 and the baffle 3 through the sealing groove, thereby ensuring the sealing effect between the frame 2 and the baffle 3. Feed pipes 4 are set on both sides of the processing box 1. Ethylene glycol butyl ether and adsorbent are transported to the stirring zone through the feed pipes 4. The adsorbent can adsorb the impurities carried in the ethylene glycol butyl ether, thereby realizing the adsorption and purification of ethylene glycol butyl ether.

[0033] like Figure 1 and Figure 2 As shown, the toothed plate 5 is mounted on the upper side of the processing box 1 via a T-shaped plate, and the movable frame 6 is slidably disposed inside the processing box 1 via a slide rail 7. A stirring mechanism is rotatably mounted on the lower side of the movable frame 6, as shown in the figure. Figure 3 As shown, the stirring mechanism includes a stirring shaft 101, a stirring rod 102, and a transmission wheel 103. The stirring mechanism can stir the ethylene glycol butyl ether and the adsorbent inside the stirring zone, thereby accelerating the adsorption speed of the adsorbent on the impurities carried in the ethylene glycol butyl ether and improving the working efficiency.

[0034] like Figure 2 As shown, the transmission mechanism is installed on the upper side of the movable frame 6, as... Figure 3As shown, the transmission mechanism includes a transmission plate 201, a U-shaped frame 202, and a transmission gear. A movable opening is provided on the upper side of the processing box 1. The width of the movable opening is adapted to the width of the transmission plate 201. When the transmission mechanism drives the movable frame 6 to move, the transmission plate 201 moves inside the movable opening, thereby enabling the transmission mechanism to drive the movable frame 6 to move horizontally. In this embodiment, the driving components are all forward and reverse motors. The transmission mechanism can drive the movable frame 6 and the stirring mechanism to move horizontally, thereby achieving uniform stirring of ethylene glycol butyl ether and adsorbent in the stirring area, and enhancing the adsorption effect of the adsorbent on impurities carried in ethylene glycol butyl ether.

[0035] like Figure 1 and Figure 2 As shown, a mounting frame 8 is inserted into the processing box 1. Two handles are installed on the mounting frame 8. The mounting frame 8 is fixed to the processing box 1 by bolts. The interior of the mounting frame 8 is provided with two sets of filter layers 9. The filter layer 9 is composed of multiple filter screens. The pore size of the multiple filter screens decreases from top to bottom. The filter layer 9 inside the mounting frame 8 can filter and separate ethylene glycol butyl ether and the adsorbent after adsorbing impurities, thereby realizing the stripping of the adsorbent remaining in ethylene glycol butyl ether.

[0036] Working principle:

[0037] Workers pour the ethylene glycol butyl ether (EDE) and adsorbent to be purified into two feed pipes 4, respectively. The EEDE and adsorbent flow into the stirring zone inside the frame 2 through the feed pipes 4. The adsorbent adsorbs impurities carried in the EEDE. Then, the reversible motor located on the moving frame 6 is started. The reversible motor drives one side of the stirring shaft 101 to rotate. The stirring shaft 101 drives the other side of the stirring shaft 101 to rotate via the transmission wheel 103 and transmission belt. The stirring shaft 101 drives the stirring rod 102 to rotate, and the stirring rod 102 stirs the EEDE and adsorbent in the stirring zone. During the stirring process, the reversible motor located inside the transmission mechanism is started. The reversible motor drives the rotating shaft to rotate, and the rotating shaft drives the transmission gear 203 to crawl along the toothed plate 5. The transmission gear 203... The rotating shaft drives the U-shaped frame 202 to move horizontally. The U-shaped frame 202 drives the moving frame 6 to slide back and forth along the slide rail 7 via the transmission plate 201. The moving frame 6 drives the stirring mechanism to uniformly stir the ethylene glycol butyl ether and adsorbent in the stirring area, which accelerates the adsorption speed of the adsorbent on the impurities carried in the ethylene glycol butyl ether and realizes the purification of ethylene glycol butyl ether. After purification, the operator pulls the spring positioning pin to release the positioning pin between the positioning plate and the baffle 3. Then, the operator pulls the baffle 3 out of the processing box 1. After being pulled out, the purified ethylene glycol butyl ether flows into the installation frame 8. When the ethylene glycol butyl ether flows through the filter layer 9, the filter screen inside the filter layer 9 filters the adsorbent remaining in the ethylene glycol butyl ether, thereby realizing the filtration and separation of ethylene glycol butyl ether and adsorbent.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
