Description

TECHNICAL FIELD

[0001] The present application relates to the field of straw conveying, in particular to a conveying anti-blocking device for a front end of straw shallow carbonization. BACKGROUND

[0002] With the development of renewable energy, the resource utilization of agricultural waste such as straw is increasingly valued. The shallow carbonization technology is a process of preparing biochar by pyrolyzing straw at low temperature under oxygen-limited or oxygen-free conditions. In this process, the straw needs to be stably and continuously fed into the pyrolysis reactor through a conveying device.

[0004] For the above-mentioned cases, the following deficiencies still exist:

[0005] For example, after harvesting the straw, it is usually necessary to wash the straw to remove the soil on the straw. Due to the characteristics of the straw, such as being fluffy, strong in fiber and high in water content, after the straw is washed, the water content in the straw clumps is high, which causes the wet straw to be easily entangled, bonded and compacted between the spiral blade and the machine shell during the conveying of the straw, resulting in blockage, reduced conveying efficiency, and even equipment shutdown.

[0006] Therefore, the present application provides a conveying anti-blocking device for a front end of straw shallow carbonization to solve the above-mentioned problems. SUMMARY

[0024] Two first gears are fixedly connected to the ends of two crushing rollers, and the two first gears mesh with each other.

[0025] The second gear is fixedly connected to the end of the crushing roller at the corresponding position of the first rack;

[0026] An arc-shaped rack is fixedly connected to the side wall of the drive ring, and the arc-shaped rack is located below the side of the arc-shaped push plate.

[0027] Preferably, the push block sidewall annular array is fixedly connected with several teeth, and the drive ring sidewall annular array is fixedly connected with several rack plates, the rack plates being located below the side of the arc-shaped rack.

[0028] Preferably, the filter plate is slidably connected in the extrusion groove, and a spring is fixedly connected between the filter plate and the extrusion groove.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] I. This invention, by setting up a rotating shaft, a swastika plate, an L-shaped shovel plate, and an L-shaped tilting frame, enables the device to periodically stir and disperse the wet straw inside the machine casing during the conveying process. At the same time, it can shovel up the wet straw for compression to remove the moisture from the straw fibers. This helps to reduce the adhesion of the material and solves the problem of low transportation efficiency caused by the excessive moisture in the straw during the conveying process.

[0034] Second, this invention, by setting up a filter screen and a drainage pool, compresses the wet straw in the groove when the extrusion block is embedded in the extrusion groove. Under the extrusion pressure, the water in the straw is squeezed out and flows out through the pores of the filter plate. It then enters the hollow rotating shaft through the L-shaped guide shell. Under the action of gravity, the water flows along the hollow rotating shaft to the drainage pool for centralized storage or discharge, thereby ensuring that the squeezed water is discharged from the L-shaped shovel plate, avoiding the re-wetting of subsequent materials by water and improving the dehydration effect.

[0035] Third, this invention, by setting up crushing rollers, enables the dehydrated straw blocks to be crushed by opposing rotations after the extrusion and dewatering process, further refining them into loose particles. Simultaneously, by integrating blade holders into the sidewalls of the extrusion blocks and creating corresponding slots in the filter plate, long fibers are simultaneously cut during the extrusion process, solving the problems of long fiber entanglement and clumping after dewatering.

Detailed Implementation

[0045] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0046] like Figures 1 to 8The device shown is a conveying anti-clogging device for the front end of straw shallow carbonization, including a housing 1, with a double helical conveying blade 2 inside the housing 1, and further including: a rotating shaft 3, which rotates on the inner side wall of the housing 1, and a rotation drive mechanism on the outer side wall of the housing 1 for driving the rotating shaft 3 to rotate; swastika plates 4 symmetrically fixedly connected to the surface of the rotating shaft 3; four L-shaped shovels 5, which are respectively fixedly connected to the four ends of the swastika plates 4, and the side walls of the L-shaped shovels 5 are provided with extrusion grooves 6; four L-shaped tilting frames 7, whose top ends are respectively rotatably connected to the side walls of the four L-shaped shovels 5, and the bottom ends of the four L-shaped tilting frames 7 are fixedly connected to extrusion blocks 8 adapted to the extrusion grooves 6; and a tilting drive assembly, which drives the L-shaped tilting frames 7 to rotate the extrusion blocks 8, so that the extrusion blocks 8 enter the extrusion grooves 6 to compress the straw in the extrusion grooves 6 and remove moisture from the straw;

[0047] The flipping drive assembly includes: two push blocks 11, which are symmetrically fixedly connected to the shaft of the L-shaped flipping frame 7, and a torsion spring 13 is fixedly connected between the push blocks 11 and the side wall of the L-shaped shovel plate 5; and two drive rings 14, which are symmetrically fixedly connected inside the housing 1, and an arc-shaped push plate 15 is fixedly connected to the side wall of the drive rings 14 near the top.

[0048] Specifically, in existing technologies, after harvesting straw, it is usually necessary to wash the straw to remove the soil. Because straw is loose, fibrous, and has a high moisture content, the straw clumps remain highly moist after washing. This causes the wet straw to easily entangle, stick, and compact between the spiral blades and the casing 1 during the conveying process, forming blockages, reducing conveying efficiency, and even causing equipment shutdown. This technical solution can solve the above problems, and the specific operation is as follows:

[0049] Start the rotary drive mechanism to drive the rotating shaft 3 and the swastika plate 4 symmetrically fixed on it to rotate inside the machine housing 1. This causes the L-shaped shovels 5 fixed at the four ends of the swastika plate 4 to rotate accordingly. The rotating L-shaped shovels 5 continuously scoop up and push the straw material at the bottom of the machine housing 1 and continuously convey it along the axial direction of the machine housing 1. The straw inside the machine housing 1 is shoveled into the L-shaped shovels 5. As the side wall of the L-shaped shovels 5 rotates, the straw inside the L-shaped shovels 5 will enter the extrusion groove 6 under the action of gravity.

[0050] After the straw in the L-shaped shovel 5 enters the extrusion groove 6, the L-shaped shovel 5 and the L-shaped tilting frame 7 connected to it rotate together with the rotating shaft 3. As the L-shaped shovel 5 continues to rotate upward, the arc-shaped push plate 15 protruding on the drive ring 14 will come into contact with the push block 11 on the L-shaped tilting frame 7. Since the drive ring 14 is fixed, the arc-shaped push block 11 will block and push the push block 11 that has moved to this point. This pushing force forces the L-shaped tilting frame 7 to rotate around its hinge point with the L-shaped shovel 5. The elastic force generated by the deformation of the torsion spring 13;

[0051] The rotation of the L-shaped flipping frame 7 drives the compression block 8 at its bottom to move into the compression groove 6 opened on the L-shaped shovel plate 5. At this time, the wet straw in the compression groove 6 is strongly compressed by the compression block 8. Some of the moisture between the straw fibers is quickly removed under mechanical compression, which also helps to crush the formed clumps.

[0052] As the device continues to rotate, after the push block 11 passes the highest point of the arc-shaped push block 11, the two disengage. Then, the torsion spring 13, which had previously accumulated elastic potential energy through torsion, is quickly released, driving the push block 11 and the L-shaped tilting frame 7 connected to it to rotate in the opposite direction, causing the extrusion block 8 to exit from the extrusion groove 6 and return to its initial position, preparing for the shoveling action in the next work cycle.

[0053] After the L-shaped tilting frame 7 drives the extrusion block 8 out of the extrusion groove 6, the straw in the extrusion groove 6 is detached from the extrusion groove 6 under the action of gravity and falls back onto the wet straw in the machine casing 1. Then, the L-shaped shovel 5 that follows will stir and mix the dry and wet straw in the machine casing 1, diluting the wet straw in the machine casing 1. On the one hand, it helps to stir and disperse the straw in the machine casing 1, reducing the accumulation of straw. On the other hand, it reduces the overall humidity value of the wet straw in the machine casing 1, which helps to further reduce the accumulation of straw and reduce the conveying pressure.

[0054] As a further embodiment of the present invention, it also includes a filter plate 18, which is disposed in the extrusion groove 6; an L-shaped guide shell 21, one end of which is fixedly connected to the extrusion groove 6 and the other end is fixedly connected to the rotating shaft 3, the rotating shaft 3 having a hollow structure; and a drainage pool 22, which is fixedly connected to the outer side wall of the housing 1.

[0055] Specifically, when the extrusion block 8 is embedded in the extrusion groove 6, the wet straw in the groove is compressed. Under the extrusion pressure, the water in the straw is squeezed out and flows out through the holes of the filter plate 18, while the solid straw fibers are intercepted by the filter plate 18 in the extrusion groove 6, thus achieving solid-liquid separation.

[0056] The water seeping out from the filter plate 18 enters the hollow rotating shaft 3 through the L-shaped guide shell 21. Under the action of gravity, the water flows along the hollow rotating shaft 3 to the drainage pool 22 for centralized storage or discharge, thereby ensuring that the squeezed water is discharged from the L-shaped shovel plate 5, avoiding the re-wetting of subsequent materials by water and improving the dewatering effect.

[0057] It should be noted that the filter plate 18 is slidably connected in the extrusion groove 6, and a spring 20 is fixedly connected between the filter plate 18 and the extrusion groove 6. During the extrusion process, the filter plate 18 undergoes slight sliding under pressure, which serves to buffer and ensure uniform contact of the extrusion surface. The spring 20 provides a restoring force. After the extrusion block 8 leaves the extrusion groove 6, the filter plate 18 is instantly reset under the action of the spring 20, thereby causing the straw on the filter plate 18 to shake, which helps the straw to quickly detach from the filter plate 18 and reduces the amount of straw residue in the extrusion groove 6.

[0058] As a further embodiment of the present invention, it also includes two crushing rollers 23, which are symmetrically rotated and connected to the top of the L-shaped shovel plate 5; several blades 24, which are linearly arrayed and fixedly connected to the two crushing rollers 23; and a rotation drive assembly, which crushes the compressed and dehydrated straw by the crushing rollers 23 under the action of gravity after straw dehydration, thereby reducing the straw clumps generated after compression.

[0059] The rotary drive assembly includes two first gears 25, which are fixedly connected to the ends of two crushing rollers 23 respectively and mesh with each other; a second gear 26, and a first rack fixedly connected to the ends of the crushing rollers 23 at corresponding positions; and an arc-shaped rack 16 fixedly connected to the side wall of the drive ring 14, which is located below the side of the arc-shaped push plate 15.

[0060] Specifically, after the extrusion action is completed, the device continues to rotate. Then, the second gear 26, which is fixedly connected to the end of one of the crushing rollers 23, engages with the arc-shaped rack 16, which is fixedly mounted on the drive ring 14 and located below the arc-shaped push plate 15. The second gear 26 rotates along the stationary arc-shaped rack 16, thereby driving the crushing roller 23 to rotate. Since the ends of the two crushing rollers 23 are linked by a pair of meshing first gears 25, the two crushing rollers 23 begin to rotate towards each other.

[0061] At this time, the straw clumps that have just been released from the extrusion trough 6 and have been dehydrated fall between two opposing rotating crushing rollers 23 as the L-shaped shovel plate 5 moves. The blades 24 on the two crushing rollers 23 thoroughly break, tear, and refine the dense block structure formed by extrusion, resulting in loose material with smaller and more uniform particle size, thus reducing the straw clumps generated after compression.

[0062] As a further embodiment of the present invention, a number of teeth 12 are fixedly connected to the side wall of the push block 11 in an annular array, and a number of rack plates 17 are fixedly connected to the side wall of the drive ring 14 in an annular array, with the rack plates 17 located below the side of the arc-shaped rack 16.

[0063] Specifically, after the second gear 26 leaves the arc-shaped rack 16 plate, as the device continues to rotate, the L-shaped shovel 5 rotates to the top of the straw and begins to stir and shovel the straw. During this process, the push block 11 intermittently passes through several rack plates 17, and through the meshing of the teeth 12 with the rack plates 17, it drives the L-shaped flipping frame 7 to move, causing the extrusion block 8 to repeatedly flip outward. On the one hand, it further disperses the straw in the machine casing 1 and reduces accumulation. On the other hand, with the extrusion block 8 opening and closing, it acts like a broom to actively sweep the straw in the machine casing 1 into the L-shaped shovel 5, which helps to ensure that there is a sufficient amount of straw in the extrusion groove 6 each time compression occurs.

[0064] As a further embodiment of the present invention, a brush 9 is fixedly connected to the bottom side wall of the extrusion block 8. It is used to sweep away the straw remaining on the L-shaped shovel plate 5 and sweep the straw on the L-shaped shovel plate 5 into the extrusion groove 6.

[0065] As a further embodiment of the present invention, several blade holders 10 are fixedly connected to the side wall array of the extrusion block 8, and the filter plate 18 has a slot 19 corresponding to the position of the blade holder 10; the blade holder 10 forcibly cuts off the long strips of straw in the extrusion groove 6, thereby reducing the cutting pressure of the subsequent crushing roller 23.

[0066] As a further embodiment of the present invention, the rotary drive mechanism includes a motor 27, which is fixedly connected to the outer wall of the housing 1. The output shaft of the motor 27 is fixedly connected to a transmission gear 28, and the end of the rotating shaft 3 is fixedly connected to a third gear 29, which meshes with the transmission gear 28. Specifically, by setting the motor 27, the transmission gear 28 and the third gear 29, the power for the rotation of the rotating shaft 3 is increased.

[0067] The working principle of this invention is as follows: Start the rotary drive mechanism to drive the rotating shaft 3 and the swastika plate 4 symmetrically fixed on it to rotate inside the machine housing 1, thereby causing the L-shaped shovel plates 5 fixed at the four ends of the swastika plate 4 to rotate accordingly. The rotating L-shaped shovel plates 5 continuously scoop up and push the straw material at the bottom of the machine housing 1, and continuously convey it along the axial direction of the machine housing 1, shoveling the straw inside the machine housing 1 into the L-shaped shovel plates 5. During the rotation of the side wall of the L-shaped shovel plates 5, the straw inside the L-shaped shovel plates 5 will enter the extrusion groove 6 under the action of gravity.

[0068] After the straw in the L-shaped shovel 5 enters the extrusion groove 6, the L-shaped shovel 5 and the L-shaped tilting frame 7 connected to it rotate together with the rotating shaft 3. As the L-shaped shovel 5 continues to rotate upward, the arc-shaped push plate 15 protruding on the drive ring 14 will come into contact with the push block 11 on the L-shaped tilting frame 7. Since the drive ring 14 is fixed, the arc-shaped push block 11 will block and push the push block 11 that has moved to this point. This pushing force forces the L-shaped tilting frame 7 to rotate around its hinge point with the L-shaped shovel 5. The elastic force generated by the deformation of the torsion spring 13;

[0069] The rotation of the L-shaped flipping frame 7 drives the compression block 8 at its bottom to move into the compression groove 6 opened on the L-shaped shovel plate 5. At this time, the wet straw in the compression groove 6 is strongly compressed by the compression block 8. Some of the moisture between the straw fibers is quickly removed under mechanical compression, which also helps to crush the formed clumps.

[0070] As the device continues to rotate, after the push block 11 passes the highest point of the arc-shaped push block 11, the two disengage. Then, the torsion spring 13, which had previously accumulated elastic potential energy through torsion, is quickly released, driving the push block 11 and the L-shaped tilting frame 7 connected to it to rotate in the opposite direction, causing the extrusion block 8 to exit from the extrusion groove 6 and return to its initial position, preparing for the shoveling action in the next work cycle.

[0071] After the L-shaped tilting frame 7 drives the extrusion block 8 out of the extrusion groove 6, the straw in the extrusion groove 6 is detached from the extrusion groove 6 under the action of gravity and falls back onto the wet straw in the machine casing 1. Then, the L-shaped shovel 5 that follows will stir and mix the dry and wet straw in the machine casing 1, diluting the wet straw in the machine casing 1. On the one hand, it helps to stir and disperse the straw in the machine casing 1, reducing the accumulation of straw. On the other hand, it reduces the overall humidity value of the wet straw in the machine casing 1, which helps to further reduce the accumulation of straw and reduce the conveying pressure.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
