[0023] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0024] like Figure 1 As shown, this embodiment provides a mobile sorting and processing device for preparing different types of RDF (Regenerative Thermal Discharge). The device includes: a housing 1, a primary screen 3, a primary blower 4, a primary lightweight material collection bin 5, a primary conveyor belt 6, a crushing bin 7, a deodorizing agent spraying device 14, a secondary screen 9, a secondary blower 12, a secondary lightweight material collection bin 13, a secondary conveyor belt 10, and a tertiary conveyor belt 11.

[0025] The top of the housing 1 has a feed inlet 2. A primary screen 3 is located inside the housing 1, below the feed inlet 2. The primary screen 3 is inclined and is a vibrating screen; vibration causes the waste material to move freely on the screen. A primary blower 4 is located on the lower side of the primary screen 3. The primary blower 4 includes a blower body and an air duct, with the air outlet of the air duct facing the corresponding screen direction. A primary lightweight material collection bin 5 is located on the higher side of the primary screen 3. When the primary blower 4 is working, it blows air to initially dry the waste and blows lightweight materials (such as plastic film, paper, etc.) from the waste material into the lightweight material collection bin 5 on the opposite side for collection. The lightweight material collection bin 5 is an integral structure with the housing 1 and has a door; opening the door allows the collected material to be removed.

[0026] The primary conveyor belt 6 is positioned below the primary screen 3, with one end inside the housing and the other end outside. The crushing chamber 7 is located below the primary screen 3 and the primary blower 4. The crushing chamber 7 is positioned lower than the primary conveyor belt 6, and a first guide baffle 16 is installed between the primary conveyor belt 6 and the crushing chamber 7 to facilitate the falling of waste into the crushing chamber 7. After the construction waste is screened by the primary screen 3, the initial removal of ash and soil is achieved. This ash and soil falls through the screen mesh and is conveyed out by the primary conveyor belt 6. The remaining construction waste is then conveyed by the primary screen 3 to the crushing chamber 7 below for crushing. The crushing chamber 7 has an upper opening and a lower opening. A dual-shaft shear crusher 8 is installed inside the crushing chamber 7. The dual-shaft shear crusher 8 includes two cooperating crushing rollers positioned at the same height and arranged in parallel. The surface of the crushing rollers has serrated protrusions, and the crushing rollers are driven to rotate by a motor. After the waste enters the crushing chamber 7, it is crushed by the dual-shaft crushing rollers.

[0027] A deodorizing agent spraying device 14 is installed on the housing 1, and its spraying range corresponds to the area above the crushing chamber 7. The deodorizing agent spraying device 14 includes a storage tank, a spraying pipe, and nozzles. The storage tank is connected to the spraying pipe via a pipe, and the spraying pipe is positioned above the crushing chamber 7 with multiple nozzles evenly distributed. During the crushing process, the deodorizing agent in the storage tank is evenly sprayed through the nozzles of the spraying pipe and falls into the crushing chamber 7 to treat the odor generated by the crushed waste.

[0028] The secondary screen 9 is located below the crushing chamber 7. The secondary screen 9 is inclined and is a vibrating screen. The secondary blower 12 is located on the lower side of the secondary screen 9; the secondary lightweight material collection chamber 13 is located on the higher side of the secondary screen 9. The mesh size of the secondary screen 9 is larger than that of the primary screen 3. The secondary blower 12 and the primary blower 4 have the same structure and working principle. The waste crushed in the crushing chamber 7 falls onto the secondary vibrating screen 9. The secondary blower 12 blows out the lightweight material produced after crushing and collects it into the second lightweight material collection chamber 13 on the opposite side. The second lightweight material collection chamber 13 is an integral structure with the housing 1 and also has a door; opening the door allows the collected material to be removed.

[0029] The secondary screen 9 separates large-diameter, high-calorific-value materials such as bamboo and wood from other small-diameter particles in the waste. The secondary conveyor belt 10 is positioned below the secondary screen 9, with one end inside the housing and the other end outside. The tertiary conveyor belt 11 is positioned below the secondary screen 9 and the secondary blower 12, with one end inside the housing and the other end outside. The tertiary conveyor belt 11 is positioned lower than the secondary conveyor belt 10, and a second guide baffle 17 is installed between the two conveyors to facilitate the falling of small-diameter waste particles into the tertiary conveyor belt 11. After screening by the secondary screen 9, large-diameter, high-calorific-value materials such as bamboo and wood remain on the screen and continue to be conveyed by vibration and gravity, eventually falling onto the tertiary conveyor belt 11 and being transported out by the tertiary conveyor belt 11 for the preparation of high-calorific-value fuel rods; while small-diameter particles fall through the screen mesh onto the secondary conveyor belt 10 and are transported out by the secondary conveyor belt 10.

[0030] The bottom of the housing 1 is equipped with wheels 15, which makes the entire device movable and convenient for operation in different decoration sites.

[0031] Furthermore, in this embodiment, a side door is also provided on the side of the box 1 at the position corresponding to the primary screen 3 and the secondary screen 9. Opening the side door allows for easy adjustment of the screen's tilt angle and replacement with screens of other aperture sizes, thereby adapting to the needs of different types of waste sorting.

[0032] In this embodiment, the housing 1 is equipped with two-stage screening modules (including a first-stage screening module and a second-stage screening module). The first-stage screening module consists of a first-stage screen 3, a first-stage blower 4, a first-stage lightweight material collection bin 5, and a first-stage conveyor belt positioned below the first-stage screen 3. The second-stage screening module consists of a second-stage screen 9, a second-stage blower 12, a second-stage lightweight material collection bin 13, and a second-stage conveyor belt 10 positioned below the second-stage screen 9. However, this is not a limitation. In other embodiments, more screening modules can be added according to the needs of other types of waste sorting. For example, the housing may have three or four screening modules. When more screening modules are set, the upper-level screening modules and the lower-level screening modules are staggered left and right. For example, the first-stage screening module is as follows: Figure 1 As shown, the second-stage screening module is located on the left side of the housing. Figure 1The first-stage screening module is located on the right side of the box, the third-stage screening module is located on the left side of the box (similar to the first-stage screening module), and the fourth-stage screening module is located on the right side of the box (similar to the second-stage screening module). The material falling through the mesh of the screen in the screening module is conveyed out by the conveyor belt below, while the lightweight material blown out by the blower is collected by the lightweight material collection bin. The material conveyed at the end of the screen is then processed by the next screening module. The material conveyed at the end of the screen of the last screening module is conveyed out by the bottom conveyor belt (similar to the bottom conveyor belt 11 in this embodiment).

[0033] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
