The primary air-blowing device 4 is arranged on the lower side of the primary screen 3. The primary air-blowing device 4 includes a blower body and a wind guiding pipe, and the air outlet of the wind guiding pipe faces the corresponding screen direction. The primary light material collection bin 5 is arranged on the higher side of the primary screen 3. When the primary air-blowing device 4 works, the blown air preliminarily dries the waste and blows the light materials (such as plastic films, paper sheets, etc.) in the waste raw materials into the light material collection bin 5 on the opposite side for collection. The light material collection bin 5 and the box body 1 are of an integral structure, and the light material collection bin 5 is provided with a bin door, and the collected materials can be taken out by opening the bin door.

[0026] The first-level conveyor belt 6 is arranged below the first-level sieve 3. One end of the first-level conveyor belt 6 is inside the box body, and the other end is outside the box body. The crushing bin 7 is arranged at the lower position between the first-level sieve 3 and the first-level air-blowing device 4. The height position of the crushing bin 7 is lower than that of the first-level conveyor belt 6, and a first guiding baffle 16 is arranged between the first-level conveyor belt 6 and the crushing bin 7 to facilitate the garbage to fall into the crushing bin 7. After the decoration garbage is screened by the first-level sieve 3, the ash in it is preliminarily removed. These ashes fall through the mesh holes of the sieve and are conveyed out through the first-level conveyor belt 6, and the remaining decoration garbage is conveyed by the first-level sieve 3 to the lower crushing bin 7 for crushing treatment. The crushing bin 7 has an upper opening and a lower opening. A double-shaft shearing crusher 8 is arranged in the crushing bin 7. The double-shaft shearing crusher 8 includes two mutually cooperating crushing rolls arranged at the same height position and in parallel. The surface of the crushing roll is provided with serrated protrusions, and the crushing roll is driven by a motor to rotate. After the garbage enters the crushing bin 7, it is crushed by the double-shaft crushing rolls.

[0027] The deodorant spraying device 14 is arranged on the box body 1, and the spraying range of the deodorant spraying device 14 corresponds to the upper position of the crushing bin 7. The deodorant spraying device 14 includes a liquid storage tank, a spraying pipeline, and nozzles. The liquid storage tank is connected to the spraying pipeline through a pipeline. The spraying pipeline is arranged above the crushing bin 7 and is evenly distributed with a plurality of nozzles.

The second-level air-blowing device 12 is arranged on the lower side of the second-level sieve 9; the second-level light material collection bin 13 is arranged on the higher side of the second-level sieve 9. The mesh holes of the second-level sieve 9 are larger than those of the first-level sieve 3. The second-level air-blowing device 12 and the first-level air-blowing device 4 have the same structure and the same working principle. The garbage crushed by the crushing bin 7 falls onto the second-level vibrating sieve 9. The second-level air-blowing device 12 is used to blow out the light materials generated after crushing and collect them into the second light material collection bin 13 on the opposite side. The second light material collection bin 13 is an integral structure with the box body 1. The second light material collection bin 13 is also provided with a warehouse door, and the collected materials can be taken out by opening the warehouse door.

[0029] The secondary screen 9 screens large particle size and high calorific value materials such as bamboo and wood in the garbage from other small particle size particles. The secondary conveyor belt 10 is arranged below the secondary screen 9. One end of the secondary conveyor belt 10 is inside the box body, and the other end of the secondary conveyor belt 10 is outside the box body. The tertiary conveyor belt 11 is arranged at the lower position between the secondary screen 9 and the secondary air blowing device 12. One end of the tertiary conveyor belt 11 is inside the box body, and the other end of the tertiary conveyor belt 11 is outside the box body.

After the secondary screen 9 screens, large particle size and high calorific value materials such as bamboo and wood remain on the screen and are continuously conveyed through vibration conveying and gravity, and finally fall onto the tertiary conveyor belt 11 and are conveyed out by the tertiary conveyor belt 11 for preparing high calorific value fuel rods; while the small particle size particles fall from the screen holes and fall onto the secondary conveyor belt 10 and are conveyed out along with the secondary conveyor belt 10.

[0030] Wheels 15 are arranged at the bottom of the box body 1, so that the whole device can be moved, which is convenient for operating at different decoration sites.

[0031] Furthermore, in this embodiment, side doors are correspondingly arranged on the side surface of the box body 1 at positions corresponding to the primary screen 3 and the secondary screen 9. Opening the side doors can facilitate adjusting the inclination angle of the screen and replacing the screen with other apertures, so as to adapt to the garbage classification requirements of other different types.

[0032] In this embodiment, two-stage screening modules (including the first-stage screening module and the second-stage screening module) are arranged in the box body 1, that is, the primary screen 3, the primary air blowing device 4, the primary light material collection bin 5 and the primary conveyor belt arranged below the primary screen 3 constitute the first-stage screening module; the secondary screen 9, the secondary air blowing device 12, the secondary light material collection bin 13 and the secondary conveyor belt 10 arranged below the secondary screen 9 constitute the second-stage screening module. However, it is not limited thereto. In other embodiments, more screening modules can also be set according to the garbage classification requirements of other types. For example, three-stage screening modules or four-stage screening modules are provided in the box body. When more screening modules are set, the upper-stage screening module and the lower-stage screening module are arranged in a left-right staggered manner. For example, the first-stage screening module is arranged on the left side of the box body as Figure 1 shown, and the second-stage screening module is as Figure 1The one shown is arranged on the right side of the box body. The third-stage screening module is arranged on the left side of the box body (similar to the first-stage screening module), and the fourth-stage screening module is arranged on the right side of the box body (similar to the second-stage screening module). The materials falling through the mesh holes of the sieve in the screening module are conveyed out through the conveyor belt below. The light materials blown by the air blowing device are collected through the light material collection bin. The materials conveyed at the end of the sieve are then processed by the next-stage screening module. The materials conveyed at the end of the sieve of the last-stage screening module are conveyed out through the conveyor belt at the bottom (similar to the conveyor belt 11 at the bottom in this embodiment).
