The central shaft 200 is rotatably installed in the delivery cylinder 100 around its own axis and is coaxial with the delivery cylinder 100 .

The auger blade 300 is rotatably installed in the conveying cylinder 100, and spirally extends from the feed hopper 110 to the discharge hopper 120 around the axis of the central axis 200 along the first rotation direction, for conveying the material entering from the feed hopper 110 to the discharge hopper. At the hopper 120 : the side of the auger blade 300 facing the feed hopper 110 is used to push the material to move, which is defined as the front side, and the side of the auger blade 300 facing the outlet hopper 120 is defined as the back side.

The cleaning part 400 is axially slidably installed on the central shaft 200 along the central axis 200. The cleaning part 400 is positioned between the two circles of blades of the auger blade 300, and alternatively contacts the front or the back of the auger blade 300, that is, the cleaning part The width of 400 in the axial direction of the central axis 200 is smaller than the distance between the front and back of the adjacent auger blade 300 .

The biomass energy particle processing and feeding device has a first rotation mode and a second rotation mode. In the first rotation mode, the cleaning member 400 is stationary relative to the delivery cylinder 100 and is located in the delivery cylinder 100 near the end of the feed hopper 110; In the rotation mode, the cleaning element 400 is attached to the front of the auger blade 300 under the obstruction of the material on the inner wall of the conveying cylinder 100 , and cleans the front of the auger blade 300 and the inner wall of the conveying cylinder 100 . By actively selecting different rotation modes, it is possible to choose whether the cleaning element 400 works, and the cleaning element 400 does not need to work passively in the delivery cylinder 100 , so it is controllable.

In this embodiment, the biomass energy particle processing and feeding device also has a third rotation mode; in the third rotation mode, the cleaning member 400 moves in a second direction opposite to the first direction and cleans the back side of the auger blade 300 Cleaning; wherein, the second rotation mode and the third rotation mode are performed sequentially. Wherein, the second rotation mode and the third rotation mode are performed sequentially. By switching different rotation modes of the central shaft 200 and the auger blade 300 , the movement of the cleaning member 400 in different directions is adjusted to clean different sides of the auger blade 300 . When the cleaning part 400 moves toward the discharge hopper 120, there are more materials adhered to the inner wall of the conveying cylinder 100, and the resistance of the cleaning part 400 to move is relatively large. and when the cleaning part 400 moves toward the feed hopper 110, since the cleaning part 400 has already cleaned the inner wall of the conveying cylinder 100 once, the resistance of the cleaning part 400 to move is small, and when it is attached to the back side of the auger blade 300, it will The positive pressure of the auger blade 300 is small. When the auger blade 300 is conveying materials, the front of the auger blade 300 is mainly in contact with the material and plays a role in promoting the material. The front of the auger blade 300 is more likely to adhere to the material. The front side of the blade 300 has a greater force, which is conducive to improving its cleaning effect; and the back of the auger blade 300 is not easy to adhere to the material, so the cleaning part 400 does not need to exert a large force on it. Conform to the actual working conditions of the auger blade 300 to improve cleaning efficiency.

In this embodiment, the first rotation mode is: both the central shaft 200 and the auger blade 300 rotate along the second rotation direction, and the rotation speed is the same; since there is no relative rotation between the central shaft 200 and the auger blade 300, the cleaning member 400 Movement in the axial direction of the center shaft 200 does not occur. The second rotation mode is: the central shaft 200 is stationary, and the auger blade 300 rotates along the second rotation direction; the auger blade 300 spirally extends from the feed hopper 110 to the discharge hopper 120 along the first rotation direction around the axis of the central shaft 200 , and the auger blade 300 rotates in a second direction relative to the central axis 200 , so the front of the auger blade 300 pushes the cleaning member 400 to move toward the end close to the discharge hopper 120 . The third rotation mode is: the central shaft 200 and the auger blade 300 both rotate along the second rotational direction, and the rotational speed of the central shaft 200 is greater than the rotational speed of the auger blade 300, so that the central shaft 200 drives the cleaning part 400 to rotate and the cleaning part 400 Pushed by the back side of the auger blade 300, it moves toward the end near the feed hopper 110. Wherein, the first rotation direction is opposite to the second rotation direction.

Since the central axis 200 is opposite to the rotation direction of the auger blade 300, the front side of the auger blade 300 pushes the cleaning part 400 to move toward the discharge hopper 120 at a faster speed. The third rotation mode is: both the central shaft 200 and the auger blade 300 rotate along the second rotation direction, and the rotation speed of the central shaft 200 is greater than the rotation speed of the auger blade 300 ; wherein, the first rotation direction is opposite to the second rotation direction.

In this embodiment, the cleaning element 400 includes a cleaning ring 410 and a cleaning block 420. There are at least two cleaning blocks 420.

An elastic member 430 is connected between the cleaning ring 410 and the cleaning block 420. The elastic member 430 promotes the cleaning ring 410 and the inner wall of the delivery cylinder 100 touch. When the cleaning ring 410 moves from one end of the feeding hopper 110 of the conveying cylinder 100 to one end of the discharging hopper 120 of the conveying cylinder 100, under the resistance effect of the material attached to the inner wall of the conveying cylinder 100 and/or the frictional resistance of the inner wall of the conveying cylinder 100, the The cleaning block 420 abuts against the front of the auger blade 300, and the cleaning block 420 cleans the front of the auger blade 300 under the rotation of the auger blade 300; When moving, the cleaning block 420 abuts against the back of the auger blade 300 under the resistance of the material attached to the inner wall of the delivery cylinder 100 and/or the frictional resistance of the inner wall of the delivery cylinder 100. When the cleaning block 420 rotates with the central shaft 200 Clean the back of the auger blade 300.

In this embodiment, the two sides of the cleaning block 420 around the central axis 200 are inclined surfaces. When the cleaning block 420 and the auger blade 300 rotate relative to each other, the inclined surface of the cleaning block 420 guides the materials attached to the auger blade 300 and the auger. Dragon Blade 300 breaks away.

In this embodiment, a biomass energy particle processing and feeding device further includes a drive mechanism, the drive mechanism includes a first motor 130 and a second motor 140, the first motor 130 is used to drive the auger blade 300 to rotate, and the second motor 140 is used to drive the central shaft 200 to rotate. The second motor 140 is a reversible motor, and the second motor 140 keeps the central shaft 200 stationary in a stopped state.

A biomass energy particle processing and feeding device of the present invention, through the rotation of the auger blade 300 along the second turning in the conveying cylinder 100, the material entering from the feed hopper 110 is transported to the discharge hopper 120, and then the material passes through the The discharge hopper 120 enters the external granule preparation machine 500 . During the material conveying process, there will be residual material on the inner wall of the conveying cylinder 100 and the surface of the auger blade 300, which will affect the conveying efficiency of the material. During the material conveying process, the central shaft 200 and the auger blade 300 adopt the first rotation mode, so that the cleaning member 400 remains stationary near one end of the feeding hopper 110 to prevent it from affecting the material conveying. When the material on the inner wall of the conveying cylinder 100 and the auger blade 300 needs to be cleaned, the central shaft 200 and the auger blade 300 adopt the second rotation mode, and the front of the auger blade 300 pushes the cleaning part 400 toward the discharge hopper One end of 120 moves; and under the resistance of the material attached to the inner wall of the delivery cylinder 100 and/or the frictional resistance of the inner wall of the delivery cylinder 100, the cleaning block 420 abuts against the front of the auger blade 300, and the cleaning block 420 is placed on the auger blade 300. The front of the auger blade 300 is cleaned under the rotation of the cleaning ring 410, and the inner wall of the delivery cylinder 100 is cleaned simultaneously. When the cleaning part 400 moves to the end of the delivery cylinder 100 close to the discharge hopper 120, the central shaft 200 and the auger blade 300 adopt the third rotation mode, and the back side of the auger blade 300 pushes the cleaning part 400 toward the feeding hopper 110. One end moves; and under the resistance effect of the material attached to the inner wall of the delivery cylinder 100 and/or the frictional resistance of the inner wall of the delivery cylinder 100, the cleaning block 420 abuts against the back of the auger blade 300, and the cleaning block 420 rotates with the central shaft 200 At the same time, the back side of the auger blade 300 is cleaned, and the cleaning ring 410 cleans the inner wall of the delivery cylinder 100 again. Since in the second rotation mode and the third rotation mode, the auger blade 300 always rotates along the second rotation direction, the cleaned material can be transported toward the direction close to the discharge hopper 120 .

And because the cleaning part 400 moves toward the end close to the discharge hopper 120, the material remaining on the inner wall of the conveying cylinder 100 is more, the resistance of the cleaning part 400 to move axially along the central axis 200 is relatively large, and the front side of the cleaning part 400 and the auger blade 300 The positive pressure on the auger blade 300 can be better cleaned when contacting. When the cleaning part 400 moves toward the end close to the feeding hopper 110, since the cleaning part 400 has cleaned the inner wall of the conveying cylinder 100 once, and in the third rotation mode, the central shaft 200 will drive the cleaning part 400 around the central shaft 200 along a spiral trajectory Moving toward the end close to the feed hopper 110, the resistance of the cleaning part 400 to move axially along the central axis 200 is small, and the positive pressure on the cleaning part 400 is small when it abuts against the back of the auger blade 300, while the auger blade 300 The back side does not play a major role in propelling the material, and there is less residual material, so there is no need for the cleaning part 400 to clean it with a greater positive pressure, which meets the actual working conditions of the auger blade 300 to improve cleaning efficiency.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
