[0028] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the utility model is further explained in detail below by combining with the drawings and specific embodiments.

The working process is as follows: the fly ash wet residue enters the drying cavity 1; since the drying unit, the screening unit and the crushing unit are communicated in sequence, the fly ash wet residue dried in the drying cavity 1 can directly reach the first screen 2 for screening; since the first screen 2 is arranged obliquely, the fly ash wet residue agglomerate larger than the screen hole diameter will slide to the second end of the first screen 2 under the action of gravity and enter the crushing cavity 3; under the action of the crushing cutter, the fly ash wet residue agglomerate is broken, and finally is transported back to the drying cavity 1 through the first feeding mechanism for the next round of processing, thereby realizing the integration of multiple processing links; the fly ash wet residue is processed in the units communicated with each other in the whole processing process, so that the fly ash wet residue will not leak or spill during the transfer process, and the environmental pollution and material waste caused by the leakage of fly ash wet residue are avoided. Meanwhile, the multiple processing links are integrated together, so that the fly ash wet residue does not need to be transferred frequently between different devices at different times, the interval between the processing links is reduced, the overall processing efficiency is improved, the fly ash wet residue can be processed quickly and efficiently, the efficiency of the whole processing process is greatly improved, and the land occupation of the equipment is reduced.
[0030] Preferably, the discharge port of the drying cavity 1 is arranged at the bottom of the drying cavity 1; further, the first screen 2 is arranged below the drying cavity 1, and the first end of the first screen 2 corresponds to the discharge port of the drying cavity 1 in the vertical direction, so that the fly ash wet residue discharged from the discharge port of the drying cavity 1 can directly fall onto the first screen 2 under the action of gravity.
