Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The biomass energy particle processing and feeding device provided by the embodiment of the invention, as shown in fig. 1 to 7, comprises a conveying cylinder 100, a central shaft 200, auger blades 300 and cleaning pieces 400.
The conveying cylinder 100 is fixed on the ground, the conveying cylinder 100 is provided with a feeding side and a discharging side, and materials move from the feeding side of the conveying cylinder 100 to the discharging side of the conveying cylinder 100; specifically, the feed side of the delivery cartridge 100 is provided with a feed hopper 110, the discharge side of the delivery cartridge 100 is provided with a discharge hopper 120, and the discharge hopper 120 is in communication with an external pellet maker 500.
The center shaft 200 is rotatably mounted in the transfer cylinder 100 about its own axis and is coaxial with the transfer cylinder 100.
Auger blade 300 is rotatably mounted within transfer drum 100 and extends helically about the axis of central shaft 200 in a first rotational direction from hopper 110 to discharge hopper 120 for transferring material entering from hopper 110 to discharge hopper 120; the side of auger blade 300 facing hopper 110 is for pushing material movement, defining a front face, and the side of auger blade 300 facing discharge hopper 120 is defined a back face.
The cleaning member 400 is slidably installed axially along the central shaft 200 to the central shaft 200, and the cleaning member 400 is positioned between two rings of the auger blade 300 and alternatively contacts the front or rear surface of the auger blade 300, i.e., the width of the cleaning member 400 in the axial direction of the central shaft 200 is smaller than the distance between the front and rear surfaces of the auger blade 300 adjacent thereto.
The biomass energy particle processing and feeding device is provided with a first rotating mode and a second rotating mode, and in the first rotating mode, the cleaning piece 400 is stationary relative to the conveying cylinder 100 and is positioned at one end, close to the feed hopper 110, of the conveying cylinder 100; in the second rotation mode, the cleaning member 400 is attached to the front surface of the auger blade 300 under the obstruction of the material on the inner wall of the delivery cylinder 100, and cleans the front surface of the auger blade 300 and the inner wall of the delivery cylinder 100. By actively selecting different rotation modes, whether the cleaning member 400 is operated or not can be selected, and the cleaning member 400 does not need to be operated passively in the delivery cartridge 100, so that the operation is controllable.
In this embodiment, the biomass energy particle processing and feeding device further 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 surface of the auger blade 300; wherein the second rotation mode and the third rotation mode are sequentially performed. 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 cleaning member 400 is adjusted to move in different directions to clean different sides of the auger blade 300. When the cleaning piece 400 moves towards the discharge hopper 120, more materials adhere to the inner wall of the conveying cylinder 100, the resistance of the cleaning piece 400 to movement is larger, and the positive pressure on the auger blade 300 is larger when the cleaning piece 400 is attached to the front surface of the auger blade 300; when the cleaning member 400 moves toward the feeding hopper 110, the cleaning member 400 has cleaned the inner wall of the conveying cylinder 100 once, so that the resistance to the movement of the cleaning member 400 is small, and the positive pressure on the auger blade 300 is small when the cleaning member is attached to the back surface of the auger blade 300. When the auger blade 300 is used for conveying materials, the front surface of the auger blade 300 is mainly contacted with the materials and plays a role in pushing the materials, and the front surface of the auger blade 300 is easier to adhere to the materials, so that the front surface acting force of the cleaning piece 400 on the auger blade 300 is larger, and the cleaning effect of the cleaning piece is improved; the back of the auger blade 300 is not easy to adhere to the material, and the cleaning member 400 does not need to exert a great force on the material. The actual working condition of the auger blade 300 is conformed to improve the cleaning efficiency.
In this embodiment, the first rotation mode is: the central shaft 200 and the auger blade 300 both rotate along the second rotation direction, and the rotation speeds are the same; since there is no relative rotation between the central shaft 200 and the auger blade 300, the cleaning member 400 does not move in the axial direction of the central shaft 200. The second rotation mode is: the central shaft 200 is stationary and the auger blade 300 rotates in a second rotational direction; auger blade 300 extends helically from hopper 110 to hopper 120 about the axis of central shaft 200 in a first rotational direction, and auger blade 300 rotates in a second rotational direction relative to central shaft 200, so that the front face of auger blade 300 pushes cleaning member 400 toward the end adjacent to hopper 120. The third rotation mode is: the central shaft 200 and the auger blade 300 both rotate along the second rotation direction, and the rotation speed of the central shaft 200 is greater than that of the auger blade 300, so that the central shaft 200 drives the cleaning member 400 to rotate and the cleaning member 400 moves towards one end close to the feeding hopper 110 under the pushing of the back surface of the auger blade 300. Wherein the first rotational direction is opposite to the second rotational direction.
In some other embodiments, the first rotation mode is: the central shaft 200 and the auger blade 300 both rotate along the second rotation direction, and the rotation speeds are the same; the second rotation mode is: the central shaft 200 rotates in the first rotation direction, the auger blade 300 rotates in the second rotation direction, and the front surface of the auger blade 300 pushes the cleaning member 400 to move toward the hopper 120 at a faster speed because the central shaft 200 and the auger blade 300 rotate in opposite directions. The third rotation mode is: the central shaft 200 and the auger blade 300 both rotate along the second rotation direction, and the rotation speed of the central shaft 200 is greater than that of the auger blade 300; wherein the first rotational direction is opposite to the second rotational direction.
In this embodiment, the cleaning member 400 includes at least two cleaning rings 410 and cleaning blocks 420, the cleaning blocks 420 are fixedly connected through the connecting block 440, the connecting block 440 is slidably mounted on the central shaft 200 along the axial direction of the central shaft 200, the cleaning blocks 420 can slide between two rings of blades of the auger blade 300, and the cleaning blocks 420 contact the front or back of the auger blade 300 at the same time. The cleaning ring 410 is coaxial with the delivery cylinder 100 and is slidably connected with the cleaning block 420 along the radial direction of the central shaft 200, and an elastic member 430 is connected between the cleaning ring 410 and the cleaning block 420, wherein the elastic member 430 urges the cleaning ring 410 to contact with the inner wall of the delivery cylinder 100. When the cleaning ring 410 moves from one end of the feed hopper 110 of the conveying cylinder 100 to one end of the discharge hopper 120 of the conveying cylinder 100, the cleaning block 420 is abutted against the front surface of the auger blade 300 under the action of the resistance of the materials attached to the inner wall of the conveying cylinder 100 and/or the friction resistance of the inner wall of the conveying cylinder 100, and the cleaning block 420 cleans the front surface of the auger blade 300 under the rotation of the auger blade 300; when the cleaning ring 410 moves from the end of the discharge hopper 120 of the delivery cylinder 100 to the end of the feed hopper 110, the cleaning block 420 is abutted against the back surface of the auger blade 300 by the resistance action of the additive on the inner wall of the delivery cylinder 100 and/or the friction resistance action of the inner wall of the delivery cylinder 100, and the cleaning block 420 cleans the back surface of the auger blade 300 when rotating along with the central shaft 200.
In this embodiment, the two sides of the cleaning block 420 around the central axis 200 are inclined surfaces, and when the cleaning block 420 rotates relative to the auger blade 300, the inclined surfaces of the cleaning block 420 guide the materials attached to the auger blade 300 to separate from the auger blade 300.
In this embodiment, a biomass energy particle processing and feeding device further includes a driving mechanism, where the driving 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 center shaft 200 stationary in a stopped state.
According to the biomass energy particle processing and feeding device, materials entering from the feed hopper 110 are conveyed to the discharge hopper 120 through rotation of the auger blade 300 in the conveying cylinder 100 along the second steering direction, and then enter the external particle preparation machine 500 through the discharge hopper 120. During the conveying process, the materials remain on the inner wall of the conveying cylinder 100 and the surface of the auger blade 300, which affects the conveying efficiency of the materials. During the material conveying process, the central shaft 200 and the auger blade 300 adopt a first rotating mode, so that the cleaning member 400 is kept stationary at a position close to one end of the feeding hopper 110, and the material conveying is prevented from being influenced. When the inner wall of the conveying cylinder 100 and the materials on the auger blade 300 need to be cleaned, the central shaft 200 and the auger blade 300 adopt a second rotation mode, and the front surface of the auger blade 300 pushes the cleaning piece 400 to move towards one end close to the discharge hopper 120; and under the resistance action of the materials attached to the inner wall of the conveying cylinder 100 and/or the friction resistance action of the inner wall of the conveying cylinder 100, the cleaning block 420 is in butt joint with the front surface of the auger blade 300, the cleaning block 420 cleans the front surface of the auger blade 300 under the rotation of the auger blade 300, and meanwhile the cleaning ring 410 cleans the inner wall of the conveying cylinder 100. The cleaning piece 400 moves to one end, close to the discharge hopper 120, of the conveying cylinder 100, and then the central shaft 200 and the auger blade 300 adopt a third rotation mode, and the back surface of the auger blade 300 pushes the cleaning piece 400 to move to one end, close to the feed hopper 110; and the cleaning block 420 is abutted against the back surface of the auger blade 300 under the resistance action of the attached material on the inner wall of the delivery cylinder 100 and/or the friction resistance action of the inner wall of the delivery cylinder 100, the cleaning block 420 cleans the back surface of the auger blade 300 when rotating along with the central shaft 200, and the cleaning ring 410 cleans the inner wall of the delivery cylinder 100 again. Because the auger blade 300 always rotates along the second direction of rotation in the second rotation mode and the third rotation mode, the cleaned material can be conveyed in a direction approaching the discharge hopper 120.
And because the cleaning piece 400 is more to the material that is close to the delivery hopper 120 one end when removing, the inner wall of transport cylinder 100 remains, and the resistance that the cleaning piece 400 axially removes along center pin 200 is great, and the positive pressure is great to it when cleaning piece 400 and the front butt of auger blade 300, can make the front of auger blade 300 obtain better cleaning performance. When the cleaning member 400 moves towards one end close to the feeding hopper 110, the cleaning member 400 cleans the inner wall of the conveying cylinder 100 once, and the central shaft 200 drives the cleaning member 400 to move towards one end close to the feeding hopper 110 along a spiral track around the central shaft 200 in the third rotation mode, so that the resistance of the cleaning member 400 to axially move along the central shaft 200 is small, the positive pressure of the cleaning member 400 is small when the cleaning member 400 is abutted against the back surface of the auger blade 300, the back surface of the auger blade 300 does not play a main pushing role on materials, and residual materials are small, so that the cleaning member 400 is not required to clean the material with large positive pressure, the actual working condition of the auger blade 300 is met, and the cleaning efficiency is improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
