[0026] The adjusting component 3 also includes a feeding component 36 installed on the side of the tower body 1 and located at the upper end of the housing 37. The feeding component 36 includes a conduit 361 fixedly connected to the upper end of the side of the tower body 1. A feed pipe 362 is installed at the upper end of the conduit 361. A cylinder 363 is installed on the side of the conduit 361 away from the tower body 1. A push plate 364 for sealing the feeding end of the tower body 1 is installed on the extended side of the cylinder 363. The push plate 364 is slidably connected to the inside of the conduit 361. The side of the tower body 1 is provided with a discharge groove that engages with the cover 39. The edge of the cover 39 is provided with... It has a sealing gasket, and the cover shell 39 is slidably connected to the inside of the shell 37; the conveying component 4 includes a receiving shell 41 installed at the bottom of the shell 37 near the end of the tower body 1, and an auger 42 is rotatably connected to the bottom of the receiving shell 41.

After each link is reset, the guide tube 361, feed pipe 362, push plate 364, and cylinder 363 cooperate to fill the tower body 1 with new packing 27.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The first three-way valve 21 is located on the upper side of the first mesh plate 28, and the second three-way valve 23 is located on the upper side of the second mesh plate 29. The second three-way valve 23 is equipped with a filter screen near the inner side of the tower body 1. By switching the direction of the first three-way valve 21 and the second three-way valve 23, the direction of introduction of anhydrous ethanol heavy liquid and anhydrous ethanol clear liquid can be switched to another set of tower bodies 1, thereby facilitating the user to replace the packing 27 in the original tower body 1.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user introduces the heavy liquid of anhydrous ethanol for extraction into a set of towers 1 through the heavy liquid feed pipe 22 and the first three-way valve 21, and introduces the clear liquid of anhydrous ethanol into the same set of towers 1 through the clear liquid feed pipe 24 and the second three-way valve 23. The heavy liquid anhydrous ethanol and the clear liquid anhydrous ethanol pass through the packing 27 and undergo compound transfer. The extraction is repeated multiple times to obtain anhydrous ethanol. The clear liquid anhydrous ethanol that has passed through the packing 27 is discharged through the clear liquid discharge pipe 25, and the heavy liquid anhydrous ethanol that has passed through the packing is discharged through the heavy liquid discharge pipe 26. When the packing 27 needs to be replaced, this is existing technology, so the specific principle will not be described in detail. The first three-way valve 21 and the second three-way valve 23 are reversed. At this time, the clear liquid anhydrous ethanol and the heavy liquid anhydrous ethanol are injected into another set of towers 1.

[0032] The hydraulic cylinder assembly 38 on the side of the original tower body 1 is activated. The hydraulic cylinder assembly 38 causes the cover shell 39 to separate from the side of the tower body 1. At this time, the inner side of the tower body 1 is connected to the inside of the shell 37. The first motor 32 and the second motor 44 are then activated. The first motor 32 drives the connecting column 34 and the adjusting plate 35 to rotate through the bevel gear assembly 33. The adjusting plate 35 moves the packing 27 and gradually sweeps the packing 27 into the shell 37. The packing that has entered the shell 37 and is located to the right of the cover shell 39 falls into the receiving shell 41. The second motor... 44 drives the auger 42 to rotate, and the rotating auger 42 discharges the packing 27 that has fallen into the receiving shell 41 through the discharge pipe 43. After the packing 27 has been discharged, the links are reset. The horizontal position of the push plate 364 is adjusted by the cylinder 363 to connect the feed pipe 362 and the guide pipe 361 with the inside of the tower body 1. The new packing 27 is introduced into the tower body 1 between the first mesh plate 28 and the second mesh plate 29 through the feed pipe 362 and the guide pipe 361. Then the links are reset to keep the tower body 1 in a closed state.
