As shown in fig. 1 to 13, the present invention provides a two-stage waste drying and incineration disposal system, which includes an incineration apparatus 10 and a residue disposal apparatus 20.

The incineration device 10 comprises a first bracket 11, a hollow blade shaft 12, a cylinder 13, a hollow blade 14, a kiln head cover 15, a kiln tail cover 16, a rotary joint 17 and a first motor 18. The hollow blade shaft 12 is obliquely arranged on the first bracket 11, and the hollow blade shaft 12 has a first cavity 121 extending in the axial direction inside and a second cavity 122 located at the periphery of the first cavity 121. The cylinder 13 is sleeved outside the hollow blade shaft 12 along the extending direction of the hollow blade shaft 12. The barrel 13 includes a drying section 131 and an incineration section 132, the incineration section 132 being located below the drying section 131.

A plurality of hollow blades 14 are provided at intervals on the hollow blade shaft 12 located at the drying section 131. The hollow blades 14 communicate with the second cavities 122 inside the corresponding hollow blade shafts 12 through the first ducts 100 and also communicate with the first cavities 121 inside the corresponding hollow blade shafts 12 through the second ducts 110. The pressurized heat medium enters the second cavity 122 in the hollow blade shaft 12 from the heat medium rotary joint 17 at the one end, gradually flows to the hollow blade 14 through the first pipeline 100, then flows back to the first cavity 121 through the second pipeline 110, and finally is discharged from the rotary joint 16. This achieves internal heating of the waste from the inside.

The kiln hood 15 is sleeved at one end of the cylinder body 13 close to the drying section 131, and the kiln hood 15 is provided with a feeding hole 151 communicated with the inside of the cylinder body 13. An igniter 163 is arranged in the kiln tail cover 16, the kiln tail cover 16 is sleeved at one end of the cylinder body 13 close to the burning section 132, and a discharge hole 161 communicated with the inside of the cylinder body 13 is formed in the kiln tail cover 16. The rotary joint 17 is arranged at one end of the hollow blade shaft 12 and is rotatably connected with the first bracket 11 through a bearing seat. The first motor 18 is arranged on the first bracket 11 and drives the hollow blade shaft 12 to rotate through the transmission of the gear set.

The residue processing device 20 includes a screw feeder 21 and a second motor 22. The spiral feeder 21 is obliquely arranged, the lower end of the spiral feeder 21 is positioned below the kiln tail cover 16 and is communicated with the discharge hole 161 on the kiln tail cover 16, the lower end of the spiral feeder 21 is provided with a water storage tank 211, and the upper end of the spiral feeder is provided with a slag hole 212. The second motor 22 is used for controlling the rotation of the feeding shaft 213 in the screw feeder 21, and the feeding shaft 213 is provided with a spiral blade 214 along the extending direction.

The residue falling from the discharge port 161 of the kiln tail cover 16 enters the lower end of the screw feeder 21 through the discharge port 161 and is mixed with the water in the water storage tank 211. The design of the water storage tank 211 prevents the residues from generating dust when falling out, and improves the working environment. After the residue is mixed with water, the residue moves upward by the rotation of the feed shaft 213 and the screw blade 214, the moisture adhered to the residue flows back to the water storage tank 211 through the gap between the screw blade 214 and the housing, and the residue falls out from the slag outlet 212 when moving to the upper end of the screw feeder 21.

The waste heat recovery device sends the waste heat of the residue in the screw feeder 21 into the barrel 13 through the kiln tail cover 16, and promotes the drying and burning of the waste in the barrel 13. The dried waste is introduced into the incineration section 132 and incinerated by the ignition of the igniter 163 in the kiln tail cover 16, and the residue after incineration of the waste falls out from the discharge port 161 by gravity.

In one embodiment, the interior of the barrel 13 has a first jacket 133 for containing a thermal medium.

Both the heat medium inlet 162 and the heat medium outlet 152 communicate with the first jacket 133 through the cavity.

After passing through the pressurizing device, preferably a pressure pump, the pressurized heat medium enters the first jacket 133 of the cylinder 13 from the heat medium inlet 162 of the kiln tail cover 16 and moves towards the kiln head cover 15. The heat medium entering the first jacket 133 first passes through the incineration stage 132, and the incineration of the waste in the incineration stage 132 further adds heat to the heat medium in the first jacket 133. The heat medium then enters the drying section 131 to exchange heat with the waste in the drying section 131, thereby drying the waste in the drying section 131 in an external heating manner. The external heating mode of the first jacket 133 is combined with the internal heating mode of the hollow blade shaft 12 and the hollow blade 14, so that the drying effect of the waste is better, and the subsequent incineration of the waste is facilitated.

The heat medium enters the cavity at the kiln tail hood 16 from the heat medium inlet 162, is diffused to the whole third cavity 31, further diffuses to the fourth cavity 32 through the first through hole 41 on the guide cylinder 40, then passes through the second through hole 134 on the first jacket 133 at the kiln tail hood 16, and finally enters the first jacket 133, so as to exchange heat with the material in the cylinder 13. The heat medium which completes the heat exchange passes through the reverse path and finally flows out from the heat medium outlet 152 on the kiln head cover 15. The guide cylinder 40 guides the flow of the heat medium, and the heat medium is uniformly diffused to the third cavity 31 and the fourth cavity 32 after being guided by the guide cylinder 40, so that the speed of the heat medium entering and exiting the first jacket 133 is more stable, and the waste is more uniformly dried.

In one embodiment, the driving device 60 includes a fixed frame 61, a dial pin 62, a third motor 63, a shift blade 64, and a shift fork 65. The fixing frame 61 is sleeved on the cylinder 13, and the plurality of shifting pins 62 are uniformly distributed on the fixing frame 61 along the circumferential direction of the fixing frame 61 and are detachably connected with the fixing frame 61. A groove 66 is formed between the fixed frame 61 and the two adjacent shifting pins 62, the third motor 63 is fixedly connected with one end of the shifting fork 65, and the shifting fork blade 64 is detachably connected with the other end of the shifting fork 65. The fork blade 64 can be inserted into and removed from the groove 66.

When the shifting fork 65 is inserted into the groove 66, the barrel 13 is driven to rotate through the fixing frame 61, the shifting fork 65 continues to rotate under the action of the third motor 63, leaves the groove 66, and continues to be inserted into the next groove 66 after one circle of rotation, so that the barrel 13 is driven to continuously rotate.
