Ethyl acetate has excellent solubility and rapid drying properties, and is widely used as a solvent, food flavoring agent, cleaning and degreasing agent, and in the production of coatings, adhesives, artificial leather, inks, and other products. Furthermore, ethyl acetate can be produced through the esterification reaction of acetic acid and ethanol, and it is easily hydrolyzed; in the presence of water at room temperature, it will gradually hydrolyze to produce acetic acid and ethanol.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a device for decolorizing ethyl acetate using molecular sieves, including a main component 1, a limiting component 2 provided on the main component 1, a decolorizing component 4 provided inside the main component 1, a lifting component 3 provided on the decolorizing component 4, and the lifting component 3 being located above the main component 1.

[0025] The main component 1 includes a decolorizing tank 11, which has an installation groove and a discharge hole. The limiting component 2 includes a gear ring 21, an adjusting gear 22, an extension member 23, a limiting member 24, and a drive gear 26. The gear ring 21, the adjusting gear 22, and the drive gear 26 are all rotatably mounted on the decolorizing tank 11. The adjusting gear 22 and the drive gear 26 are both meshed with the gear ring 21. The extension member 23 is mounted on the adjusting gear 22, and the limiting member 24 is mounted on the extension member 23.

[0026] Specifically, during the decolorization process, the decolorization component 4 can be first placed on the main component 1. To prevent the decolorization component 4 from shifting or detaching during the decolorization process, a toothed ring 21 and an adjusting gear 22 can be placed on the decolorization tank 11. Since the toothed ring 21 can rotate around the surface of the decolorization tank 11 and the adjusting gear 22 can rotate on its own axis, and the two mesh, rotating the toothed ring 21 can drive the adjusting gear 22 to rotate. Since the adjusting gear 22 is provided with an extension 23 and a limiting member 24, the limiting member 24 can be placed directly above the decolorization component 4 by rotating the adjusting gear 22, thereby limiting the decolorization component 4 and preventing it from detaching. In use, the toothed ring 21 can be rotated by rotating the drive gear 26.

[0027] In this embodiment, the limiting component 2 also includes an A motor 25, which is located above the decolorizing tank 11, and the output end of the A motor 25 is connected to the drive gear 26.

[0028] Specifically, in order to enable automated rotation during use, an A motor 25 is installed on the decolorization tank 11, and the output end of the A motor 25 is connected to the drive gear 26. Thus, by starting the A motor 25, the drive gear 26 can be rotated.

[0029] In this embodiment, the decolorization component 4 includes a mounting plate 41, a B-screw 42, and a molecular sieve 43. The mounting plate 41 is disposed in the mounting groove, the B-screw 42 is disposed on the mounting plate 41, and the molecular sieve 43 is disposed on the B-screw 42.

[0030] Specifically, during the decolorization process, the mounting plate 41 can be placed in the mounting groove, and a B screw 42 can be installed on the mounting plate 41. The B screw 42 is composed of multiple screws of different diameters. At this time, multiple molecular sieves 43 can be threaded onto the B screw 42 to complete the setting of the molecular sieves 43.

[0031] In this embodiment, the lifting assembly 3 includes an A lead screw 33, a fixed rod 34, and a lifting component 35. The fixed rod 34 is fixedly mounted on the decolorizing tank 11, the lifting component 35 is slidably sleeved on the fixed rod 34, the A lead screw 33 is rotatably mounted on the mounting plate 41, and the lifting component 35 is threaded onto the A lead screw 33.

[0032] Specifically, when it is necessary to replace the molecular sieve 43, the lifting component 35 can be moved up and down by rotating the lead screw 33. Since the lifting component 35 is set on the mounting plate 41, when the lifting component 35 rises, it will drive the mounting plate 41 to rise together, thereby driving the decolorization component 4 to rise as a whole. After rising to a certain height, the molecular sieve 43 can be replaced.

[0033] In this embodiment, the lifting assembly 3 also includes a B motor 31 and a rotating component 32. The rotating component 32 is mounted on the A lead screw 33, and the B motor 31 is mounted on the rotating component 32. The output end of the B motor 31 passes through the rotating component 32 and is connected to the A lead screw 33.

[0034] Specifically, in order to automate the rotation of lead screw A 33, a rotating component 32 can be installed on lead screw A 33, and a motor B 31 can be installed on the rotating component 32. The output end of motor B 31 is connected to lead screw A 33, so that the rotation of lead screw A 33 can be controlled by starting motor B 31.

[0035] In this embodiment, the main component 1 also includes a support member 12 and a valve 13. The valve 13 is disposed in the unloading trough, and the support member 12 is disposed at the lower end of the decolorization tank 11.

[0036] Specifically, during use, the entire device can be supported by the support member 12, and after the decolorization operation is completed, the ethyl acetate can be discharged through the valve 13.

[0037] In this embodiment, the decolorizing tank 11 is provided with a plurality of snap rings 14, and the inner diameter of the plurality of snap rings 14 increases sequentially from bottom to top.

[0038] Specifically, in use, since the diameters of the multiple molecular sieves 43 decrease sequentially from top to bottom, in order to support the multiple molecular sieves 43, multiple retaining rings 14 are provided in the decolorization tank 11, and the inner diameters of the multiple retaining rings 14 increase sequentially from bottom to top, so that the molecular sieves 43 can be placed on the retaining rings 14.

[0039] The working principle and usage process of this utility model are as follows: When decolorizing ethyl acetate, the decolorizing component 4 can be set inside the main component 1 first. Then, the decolorizing component 4 can be limited by the limiting component 2 to prevent the position of the decolorizing component 4 from shifting during the subsequent decolorization process. Then, the ethyl acetate can be decolorized by the decolorizing component 4. When the molecular sieve 43 needs to be replaced after long-term use, the height of the decolorizing component 4 can be adjusted by the lifting component 3. At this time, the molecular sieve 43 can be replaced quickly and conveniently, which facilitates the subsequent decolorization process.

[0040] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
