[0053] By providing a movable blocking structure, it is possible to prevent particles from entering the drain box 21 when the storage box 22 is replaced, thereby preventing the use of the drain box 21 and the storage of the storage box 22 from being affected.

[0058] In the embodiment of the present invention, when in use, the breaking structure rotates, thereby driving the first rotating rod 13 to rotate through the second transmission bevel gear 16, and then driving the first transmission bevel gear 15 on the second rotating rod 14 to rotate, and then indirectly driving the cleaning structure to engage and connect;

[0059] By setting the transmission structure, it is convenient to transmit the force generated by the breaking up structure to the cleaning structure during use, thereby facilitating the cleaning of the surface of the filter plate 9.

[0060] like Figure 3 、 Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the scattering structure includes a third rotating rod 7 and scattering blades 8, the third rotating rod 7 is movably installed in the middle of the processing tank 1, the scattering blades 8 are arranged in a conical array on the surface of the third rotating rod 7, and the rear end of the third rotating rod 7 is fixedly installed with a driving bevel gear 17.

[0070] The dripping water will pass through the filter plates 9 at different levels, so that the particles contained therein are filtered out, and the clean absorption liquid falls into the absorption liquid tank 4, thereby completing the recovery of the absorption liquid and making it recyclable;

[0071] When the third rotating rod 7 rotates, it drives the active bevel gear 17 to rotate, which in turn indirectly drives the second transmission bevel gear 16 on the first rotating rod 13 to rotate, and then indirectly drives the second rotating rod 15 on the first transmission bevel gear 14 to rotate, and finally rotates the driven bevel gear 11 on the top of the rotating shaft 10, thereby rotating the scraper 18 and rotating the particles on the top of the filter plate 9 to the through hole 19, and then enter the slag discharge pipe 20, and finally enter the storage box 22, and then the water contained therein will pass through the filter screen provided on its surface, so that the water contained therein will fall to the lower end of the drain tank 21, and then be pumped back to the absorption liquid tank 4 by the return pipe 23, thereby avoiding the accumulation of particles and affecting the filtering effect of the absorption liquid;

[0072] When the storage box 22 is full, the lower end of the sealing block 28 is squeezed out during replacement, so that the sealing block 28 moves inward under the action of the spring 27 on the guide rod 26, so that the inner end of the sealing block 28 is inserted into the slot 24, thereby blocking the lower end of the slag discharge pipe 20, thereby preventing particulate matter from entering the drain box 21 during replacement and affecting subsequent cleaning.
