The conveying unit 3 includes a conveying member 31 extending along a feeding path L1 and suitable for conveying the object to be screened 1 , and two baffles 32 respectively connecting opposite sides of the conveying member 31 . The conveying member 31 is preferably a sloping plate extending obliquely downward along the feeding path L1, but not limited thereto, the conveying member 31 is formed on the feeding path L1 and extends transversely to the feeding path L1 perpendicular to the feeding path L1. The air outlets 30 of the baffles 32 . In addition, it should be noted that FIG. 2 is a cross-sectional view of FIG. 1 with the feeding path L1 as a section line, so that only one of the baffles 32 is shown in FIG. 2 .

The air supply unit 4 communicates with the air outlet 30 and is preferably a blower, but not limited to this, as long as it can communicate with the air outlet 30 to provide wind pressure. The air supply unit 4 provides a wind pressure in the direction of the air outlet 30 to blow up the unburned substances 11 , but not enough to blow up the gas G of the granular bottom slag 12 , thereby making the unburned substances 11 It leaves the feeding path L1 and is displaced along a projection path L2 that intersects the feeding path L1. It should be noted that the projection path L2 of the first embodiment will vary and deviate with the area and weight of each unburned object 11 , so the projection path L2 shown in FIG. 2 is not used. The trajectory shape of the shooting path L2 is limited as long as the unburned substances 11 can reach the guide unit 5 from the conveying member 31 .

The guide unit 5 is located on the projection path L2 and is adapted to catch the unburned objects 11 and move the unburned objects 11 along a guide path L3 intersecting with the projection path L2. The guide unit 5 includes a roller 51 which is spaced from the end of the conveying member 31 and rotates with an axis A extending laterally perpendicular to the guide path L3 as a rotation axis, and a roller 51 abutting on the outer peripheral surface of the roller 51 and away from the guide path L3. A guide member 52 of the conveying unit 3 extending along the guide path L3, a driving member 53 for driving the rotation of the drum 51, and a driving member 53 placed downstream of the guide member 52 and suitable for intercepting flying over the guide The intercepting nets 54 of the unburned materials 11 of the pieces 52 . The roller 51 and the end of the conveying member 31 are spaced to define a discharge space E which is located below the projection path L2 and is suitable for the passage of the granular bottom slag 12 and dust particles. The guide member 52 is preferably a slanted plate extending downward along the guide path L3, but not limited to this, as long as the unburned materials 11 can be transported. In addition, it should be noted that the feeding path L1 and the guiding path L3 shown in FIG. 2 are parallel to each other, but the first embodiment is not limited to this, as long as the unburned materials 11 can be transported by the conveying member 31 can be moved to the guide unit 5 .

When using the first embodiment, firstly, the object to be screened 1 absorbs a large amount of water through the operation of the humidifying unit 2, and is driven by its own gravity to slide on the conveying member 31 along the feeding path L1, and The baffles 32 can prevent the object to be screened 1 from falling to the outside of the two sides of the conveying member 31 during the moving process. Next, when the object to be screened 1 moves to the When the air outlet 30 is blown up by the wind pressure generated by the flow of the gas G, the unburned materials 11 are pushed by the gas G due to the large wind-receiving area. The granular bottom slag 12 can continue to move to the discharge space E along the feeding path L1 due to the small wind-receiving area, that is to say, The unburned materials 11 can be directly separated from the granular bottom slag 12 through this step, and move along a different path from the granular bottom slag 12, thereby completing the sorting operation of the unburned materials 11 . Finally, the unburned materials 11 cross the discharge space E along the projection path L2 and fall on the drum 51 . Because of the moisture content, the unburned materials 11 can produce particles attached to the outer peripheral surface of the drum 51 . Adhesion does not fall, and the roller 51 is pivoted in the direction of the arrow as shown in FIG. The unburned materials 11 on the guide member 52 can move along the guide path L3 and are transported to the storage area to complete the operation of being separated from the granular bottom slag 12 and stored separately. In addition, it should be noted that, since the projection path L2 is different due to the gravity of the unburned objects 11 themselves and the difference in the wind receiving area, the unburned objects 11 may not necessarily fall on the drum 51 , and of course it may Either directly on the guide 52 or directly on the intercepting net 54, both can be separated from the granular bottom slag 12.

Therefore, through the influence of the gas G provided by the air supply unit 4 to push the object 1 to be screened, the unburned materials 11 and the granular bottom slag 12 can be sorted out, and the The same moving path can facilitate collection and storage for subsequent reuse. In addition, the design of the roller 51 being driven by the driving member 53 to pivot automatically, It can drive the unburned materials 11 falling on the drum 51 to move on the guide member 52 , so as to avoid a large amount of the unburned materials 11 being stored on one end of the guide unit 5 and affecting the subsequent conveying.

Referring to FIG. 3 and FIG. 4 , it is a second embodiment of the unburnt sorting device of the present invention. The difference from the first embodiment is that the shape of the conveying unit 3 is different from that of the first embodiment. Furthermore, the paths of the gas G flowing are also different. The conveying unit 3 includes a conveying member 31 extending along the feeding path L1 and spaced from the drum 51 to define the discharge space E; The device 31 conveys the driving roller 33 of the object to be screened 1, and a driving belt 34 that connects the driving roller 33 and the guide unit 5 to the roller 51 and enables the driving roller 33 and the roller 51 to interlock with each other. The conveying member 31 is preferably a conveying belt, but not limited thereto. The discharge space E is located below the feed path L1 and the projection path L2, and defines a gas flow line L4 passing through the discharge space E and the feed path L1 (Fig. 4 does not depict the feed path L1 due to simplified illustration). intersection with the gas flow line L4). The air supply unit 4 can provide the gas G along the direction of the gas flow line L4 to push the object to be screened 1, and the wind pressure of the gas G is not enough to blow up the granular bottom slag 12, but can push the Unburnt 11. 4 does not show the intersection of the feeding path L1 and the projection path L2, and does not show the intersection of the projection path L2 and the guide path L3, to avoid visually confusing condition.

Therefore, the second embodiment can also complete the sorting operation of the unburned substances 11 and the granular bottom slag 12 through the pushing of the gas G, and the driving member 53 only needs to drive When the drum 51 is pivoted, the drive roller 33 can be driven to rotate, so that the object to be screened 1 can be conveyed actively and smoothly, thereby saving the additional cost of driving the conveying member 31 to operate.

To sum up, the unburned material sorting device of the present invention can sort the unburned material 11 and the granular bottom slag 12 from the to-be-screened material 1 through the operation of the air supply unit 4, and separate them along the The projecting path L2 and the feeding path L1 are conveyed to two places, thereby completing the sorting and storage. Therefore, a large number of objects to be screened 1 can be processed, and the unburned materials 11 and the granular bottom slag 12 can be sorted out in real time, thereby improving the operation efficiency and facilitating subsequent reuse, so the cost can be effectively achieved. purpose of the invention.
