[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-5 The utility model provides a technical solution: a slag treatment device for incineration of domestic waste, including an incinerator 1 and a slag discharge pipe 11, a guide pipe 16 fixedly connected to the upper end of the slag discharge pipe 11 is fixedly installed on the lower end surface of the incinerator 1, and the guide pipe 16 is communicated with the incinerator 1 and the inner cavity of the slag discharge pipe 11, a motor box 12 is fixedly installed on the outer end surface of the slag discharge pipe 11, an auger spiral blade 13 fixedly connected to the output shaft at the outer end of the motor box 12 is rotatably installed in the slag discharge pipe 11, a mounting sleeve 14 is fixedly installed on the periphery of the slag discharge pipe 11, and a waste heat recovery pipe 15 spirally sleeved on the periphery of the slag discharge pipe 11 is fixedly installed in the mounting sleeve 14.

[0023] Working principle: When the ash after burning in the incinerator 1 is guided to the slag discharge pipe 11 through the guide pipe 16, the motor inside the motor box 12 is started, and the auger spiral blade 13 can be driven to rotate in the slag discharge pipe 11 through its outer end output shaft, so as to achieve the effect of guiding the ash out of the slag discharge pipe 11;

[0024] A waste heat recovery pipe 15 is arranged outside the slag discharge pipe 11. Through an external water pump, low-temperature moisture can be guided into the waste heat recovery pipe 15, so that it can absorb the heat in the ash inside the slag discharge pipe 11, thereby achieving the effect of heating the moisture, which can not only improve the utilization rate of heat, but also cool the ash.

[0025] Example 2

[0026] A movable block 2 is inserted and installed in the guide tube 16, the upper end of the movable block 2 is conical, and a movable sleeve 20 is fixedly installed on the lower end surface of the movable block 2. A reciprocating screw 23 that is mutually sleeved with the inner cavity of the movable sleeve 20 is rotatably installed in the guide tube 16, and a convex block 22 that matches the outer thread of the reciprocating screw 23 is fixedly installed on the inner wall of the movable sleeve 20. A limiting sleeve 21 that matches the inner wall clearance is fixedly installed in the guide tube 16 through a connecting rod. The movable sleeve 20 and the reciprocating screw 23 are respectively inserted and It is rotatably installed in the limit sleeve 21, and a limit slide groove 24 is provided on the inner wall of the limit sleeve 21. A limit slider 25 that slides with the limit slide groove 24 is fixedly installed on the periphery of the movable sleeve 20.

The auger spiral blade 13 and the first rotating rod 26, the first rotating rod 26 and the second rotating rod 27, and the second rotating rod 27 and the reciprocating screw 23 are meshed and connected with each other through a bevel gear set.

[0027] When the auger spiral blade 13 rotates, the bevel gear set is meshed with each other between it and the first rotating rod 26, between the first rotating rod 26 and the second rotating rod 27, and between the second rotating rod 27 and the reciprocating screw 23, so that the rotating auger spiral blade 13 can drive the reciprocating screw 23 to rotate in the limiting sleeve 21. Under the restriction of the movement direction of the movable sleeve 20 by the sliding cooperation between the limiting slider 25 and the limiting groove 24 of the limiting sleeve 21, the rotating reciprocating screw 23 can drive the movable sleeve 20 and its upper end movable block 2 to move up and down through the threaded cooperation between it and the protrusion 22. When the movable block 2 moves upward to the upper side of the guide pipe 16, the ash inside the incinerator 1 can enter the guide pipe 16 through the gap between the two, and when it moves downward, the ash inside the guide pipe 16 can be pressed downward, thereby avoiding the ash from being blocked in the guide pipe 16.
