[0030] like Figure 3 and Figure 4 As shown, the pulverizing mechanism 6 includes a pulverizing chamber 603 fixedly installed in the mechanism housing 2, a first pulverizing roller 604 and a second pulverizing roller 605 are movably installed in the pulverizing chamber 603, a rotating shaft 608 is fixedly installed on the first pulverizing roller 604 and the second pulverizing roller 605, a linkage gear 601 is fixedly installed at the end of the rotating shaft 608, and the two groups of linkage gears 601 are meshed with each other, a first reducer 606 is connected to the rotating shaft 608, a first input shaft 609 is provided on the first reducer 606, a first bevel gear 607 is provided on the first input shaft 609 and the driving shaft 5, and the two groups of first bevel gears 607 are meshed with each other, a first feed port 602 is opened at the upper end of the pulverizing chamber 603, and the slag funnel 1 is connected to the pulverizing chamber 603 through the first feed port 602.

[0031] Specifically, after being decelerated by the first reducer 606, the driving shaft 5 can drive the rotating shaft 608 to rotate slowly. After the rotating shaft 608 rotates slowly, it will drive the first crushing roller 604 and the second crushing roller 605 to rotate slowly. During the slow rotation of the first crushing roller 604 and the second crushing roller 605, the larger ash will be crushed, and the crushed ash will fall into the cooling chamber 703.

[0036] Working principle: the ash produced by incineration is transported to the crushing cabin 603 through the slag hopper 1. After the ash is transported to the crushing cabin 603, the driving motor 4 can be started. After the driving motor 4 is started, the driving shaft 5 will be driven to rotate. Under the action of the first bevel gear 607, the driving shaft 5 can drive the first input shaft 609 to rotate. After being decelerated by the first reducer 606, the driving shaft 5 can drive the rotating shaft 608 to rotate slowly. After the rotating shaft 608 rotates slowly, it will drive the first crushing roller 604 and the second crushing roller 605 to rotate slowly. During the slow rotation of the first crushing roller 604 and the second crushing roller 605, the larger ash will be crushed, and the crushed ash will fall into the cooling cabin 703. When the ash falls into the cooling cabin 703, the driving shaft 5 will drive the movable shaft 710 to rotate under the action of the second bevel gear 705. After the movable shaft 710 rotates, it will drive the fan blades 706 to rotate.

The mud that falls to the bottom of the cooling chamber 703 will enter the extruder barrel 801 through the second feed port 802, and when the mud enters the extruder barrel 801, the drive shaft 5 will drive the second input shaft 808 to rotate under the action of the third bevel gear 809, and the driving shaft 5 will drive the extruding screw 803 at the end of the transmission shaft 806 to rotate slowly under the action of the second reducer 807. After the extruding screw 803 rotates slowly, it will squeeze the mud residue to move forward along the extruder barrel 801. The mud residue moving forward along the extruder barrel 801 will be discharged through the discharge hole 804 on the sealing end cover 805, so that the ash residue is squeezed into particles for discharge, thereby reducing the dust generated during transportation.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
