[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please refer to Figures 1 to 3 This utility model provides a solvent treatment device for a flexographic printing plate washing machine, including a filtration mechanism 3, a three-way control valve 2, a vacuum pump 4, and a distillation mechanism 1;

[0036] The two inlet ports of the three-way control valve 2 are connected to the filter mechanism 3 and the vacuum pump 4, respectively, and the outlet port of the three-way control valve 2 is connected to the distillation mechanism 1.

[0037] In use, the solvent mixed with flexographic material enters the filtration mechanism 3, which removes undissolved flexographic material and other impurities from the solvent. The filtered solution then enters the distillation mechanism 1 through the three-way control valve 2. The three-way control valve 2 connects the vacuum pump 4 to the distillation mechanism 1, which evacuates the interior of the distillation mechanism 1 to improve its distillation efficiency. The distillation mechanism 1 is then used to separate the dissolved flexographic material through distillation, thereby recovering the solvent mixed with the flexographic material.

[0038] In this embodiment, the filtration mechanism 3 includes a filter tank and a filter screen 35. The top of the filter tank is provided with a feed inlet, and the bottom of the filter tank is connected to a three-way control valve 2. The filter screen 35 is installed inside the filter tank, and the filter screen 35 is used to filter undissolved flexographic material and other impurities.

[0039] In this embodiment, the filter vessel includes an upper vessel body 31, a lower vessel body 32, and a lifting cylinder 34;

[0040] An annular connecting plate 33 is provided on the outer wall of both the bottom opening of the upper vessel body 31 and the top opening of the lower vessel body 32.

[0041] Two sets of lifting cylinders 34 are provided, which are arranged oppositely on the annular connecting plate 33 on the lower vessel body 32. The piston rod on the lifting cylinder 34 is connected to the annular connecting plate 33 on the upper vessel body 31.

[0042] The inner wall of the lower vessel 32 is provided with an annular protrusion, and the filter screen 35 is disposed on the annular protrusion;

[0043] In use, the upper vessel 31 is moved upward by lifting cylinder 34, thereby separating the upper vessel 31 and the lower vessel 32. At this time, it is easy to remove the filter screen 35 in the lower vessel 32 for replacement or maintenance, making it more convenient to use.

[0044] In this embodiment, sealing grooves are provided at the bottom of the upper vessel body 31 and the top of the lower vessel body 32. When the upper vessel body 31 and the lower vessel body 32 are combined, the sealing grooves form a sealing cavity. A sealing ring is installed in the sealing cavity. The sealing ring ensures good airtightness when the upper vessel body 31 and the lower vessel body 32 are combined.

[0045] In this embodiment, the distillation mechanism 1 includes a distillation kettle 11, a heating assembly 12, a connecting pipe 13, a condenser pipe 14, and a drain pipe 15;

[0046] Heating assembly 12 is installed inside distillation vessel 11;

[0047] One end of the bottom of the connecting pipe 13 is connected to the top of the distillation vessel 11, and the other end of the bottom of the connecting pipe 13 is connected to the condenser 14 and the drain pipe 15 in sequence.

[0048] A control valve is installed on the drain pipe 15;

[0049] After the solvent is heated in the distillation vessel 11, the generated hot vapor enters the condenser 14 and is condensed into liquid, which is then discharged from the drain pipe 15, thus realizing the distillation of the solvent.

[0050] In this embodiment, the heating component 12 is an electric heating tube.

[0051] In this embodiment, the bottom of the distillation vessel 11 is provided with multiple support legs 16.

[0052] In this embodiment, a discharge pipe 17 is provided at the bottom of the distillation vessel 11.

[0053] The working principle of this utility model is as follows:

[0054] Solvent containing flexographic material enters the filtration mechanism 3, where undissolved flexographic material and other impurities are removed. The filtered solution then enters the distillation mechanism 1 through the three-way control valve 2. The three-way control valve 2 connects the vacuum pump 4 to the distillation mechanism 1, which evacuates the interior of the distillation mechanism 1 to improve its distillation efficiency. The distillation mechanism 1 is then used to separate the dissolved flexographic material through distillation, thereby enabling the recovery of the solvent containing the flexographic material.
