[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] See Figures 1 to 6 .

[0022] A polymeric ethylene glycol recovery device includes a base frame 1, with a collection box 2 connected to the top of the base frame 1. Specifically, limiting angle plates 41 are connected to the four corners of the base frame 1, and four slots 42 corresponding to the four limiting angle plates 41 are opened below the collection box 2. The limiting angle plates 41 are inserted into the slots 42 corresponding to themselves.

[0023] A shelf is placed on top of the collection box 2. Specifically, steps 31 are connected to both the left and right sides of the collection box 2, and the shelf is placed on top of the two steps 31. The shelf includes an outer frame 3 and a shelf body 4 integrated with the outer frame 3. The shelf body 4 is located inside the outer frame 3. Several filter frames 5 are detachably connected to the outer frame 3. The filter frames 5 are located below the shelf body 4, and the bottom plate of the filter frames 5 has filter holes 6. Specifically, horizontal sliding grooves 11 are opened on both the front and rear sides of the base frame 1. The front and rear sides of the filter frames 5 are respectively connected to screw assemblies corresponding to the two horizontal sliding grooves 11. The screw assembly includes two vertical screws 12 arranged on the left and right sides. The upper ends of the two vertical screws 12 pass through the horizontal sliding grooves 11 and are threaded with nuts 13. A liquid outlet pipe 7 is connected to the bottom of the collection box 2. More specifically, two filter frames 5 are detachably connected to the outer frame 3 of this utility model.

[0024] Preferably, the filter frame 5 is connected to two limiting plates 21 arranged front and back on both the left and right sides. The upper end of the limiting plate 21 passes between the outer frame 3 and the shelf 4 and is located above the shelf 4.

[0025] Instructions for use: When using this utility model, first, the polymer residue needs to be placed in a woven bag. It is best to have a small hole at the bottom of the woven bag. Then, place the woven bag with the small hole on the support frame 4 (the support frame 4 will bear the weight), and the woven bag should be directly above the filter frame 5 (see reference). Figure 1 With the design of the limiting plate 21, it is easy to observe whether the woven bag is located in front of the filter frame 5. After the woven bag is placed on the shelf 4 for a period of time, due to the influence of gravity, the ethylene glycol in the polymerization residue flows out from the small hole at the bottom of the woven bag and falls into the filter frame 5. It is then filtered by the filter hole 6 of the filter frame 5 and collected in the collection box 2. The ethylene glycol in the collection box 2 can be discharged through the liquid outlet pipe 7. Preferably, a valve can be installed on the liquid outlet pipe 7. The present invention can easily separate the ethylene glycol by means of the above method. In addition, the filter frame 5 is connected by a detachable connection structure, which is convenient for subsequent disassembly and cleaning.
