Detailed implementation mode

[0043] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a biomass alternative fuel feeding improvement device includes:

[0044] Fixed frame 1;

[0045] Three-stage feeding device 2, having three stages, namely upper-side feeding section 21, middle-side feeding section 22 and lower-side feeding section 23;

[0046] Material bin 3, fixed between the fixed frames 1, and the three-stage feeding device 2 is arranged in the material bin 3;

[0047] Discharge platform 5, arranged below the lower-side feeding section 23, corresponding to the discharge port 4;

[0048] Staggered feeding sawtooth unit 6, fixed on the feeding section;

[0049] Offset fork-type sawtooth bushing unit 7, symmetrically distributed in two groups, fixed at both ends of the feeding section.

[0050] In this embodiment, the upper-side feeding section 21, the middle-side feeding section 22 and the lower-side feeding section 23 have the same structure.

[0051] As a preferred embodiment, the axial center distance between the upper-side feeding section 21 and the middle-side feeding section 22 is 320 mm, and the axial center distance between the middle-side feeding section 22 and the lower-side feeding section 23 is 370 mm; the axial center height difference between the upper-side feeding section 21, the middle-side feeding section 22 and the lower-side feeding section 23 is 1300 mm; the axial center offset design effectively alleviates the problem of material accumulation in the front section of the lower-side feeding section 23.

[0052] In this embodiment, the upper-side feeding section 21 includes:

[0053] Feeding shaft assembly 211, rotatably arranged between the fixed frames 1, and connected to an external driving mechanism;

[0054] The adjusting assembly 212 is provided with two groups symmetrically distributed, fixed at both ends of the material feeding shaft assembly 211, and located in the material bin 3;

[0055] The positioning frame 213 is rotatably connected to the side of the adjusting assembly 212 and fixedly connected to the side wall of the material bin 3;

[0056] The moving assembly 214 is arranged between the two adjusting assemblies 212 on both sides and is slidably connected to the material feeding shaft assembly 211.

[0057] That is to say, during the rotation of the material feeding shaft assembly 211, the materials in the material bin 3 are scattered and fed under the action of the staggered material feeding sawtooth unit 6 and the offset fork-shaped sawtooth bushing unit 7. After being agitated by the upper side material feeding section 21 and the middle side material feeding section 22, the materials are agitated by the lower side material feeding section 23 and enter the discharge platform 5 through the discharge port 4 at the bottom of the material bin 3. The discharge platform 5 conveys the materials to the combustion furnace. Through the multi-section material feeding setting and by adjusting the axial distance between the material feeding sections under the design of the axial offset, the flow path of the materials during the material feeding process is changed, enabling the materials to transition more smoothly from one material feeding section to another during the flow process, effectively reducing the accumulation of materials caused by the unsmooth flow path.

[0058] In this embodiment, the material feeding shaft assembly 211 includes:

[0059] The rotating shaft section 2111 is rotatably connected to the fixed frame 1 and fixedly connected to the adjusting assembly 212;

[0060] The polygonal shaft body 2112 is coaxially arranged with the rotating shaft section 2111 and is fixed between the adjusting assemblies 212;

[0061] The outer shaft sleeve 2113 is arranged outside the polygonal shaft body 2112 and is fixed between the adjusting assemblies 212.

[0062] That is to say, driven by the rotating shaft section 2111, the polygonal shaft body 2112 and the outer shaft sleeve 2113 rotate synchronously, and at the same time drive the adjusting assembly 212 to rotate, thereby driving the staggered material feeding sawtooth unit 6 and the offset fork-shaped sawtooth bushing unit 7 to agitate the materials on the positioning frame 213 and convey the materials.

[0063] In this embodiment, the adjusting assembly 212 includes:

[0064] The fixed ring 2121 is fixed on the rotating shaft section 2111;

[0065] The adjusting ring surface 2122 is rotatably arranged in the fixed ring 2121, and continuous undulating blocks are provided on the opposite sides of the two ends of the adjusting ring surface 2122.

[0066] That is to say, when the fixed ring 2121 and the adjusting ring surface 2122 rotate along with the rotating shaft section 2111, the adjusting ring surface 2122 can rotate within the fixed ring 2121 to adjust the moving assembly 214, thereby adjusting the sawtooth distribution on the staggered feeding sawtooth unit 6, uniformly stirring the material, and effectively reducing the accumulation of the material.

[0067] In this embodiment, the moving assembly 214 includes:

[0068] A plurality of moving plates 2141 are annularly distributed, are slidably connected to the feeding shaft assembly 211, and are arranged between the adjusting assemblies 212;

[0069] A pushing shaft body 2142 is fixed to one end of the moving plate 2141 and is in contact with the adjusting ring surface 2122;

[0070] A telescopic connecting piece 2143 is fixed to the end of the moving plate 2141 opposite to the pushing shaft body 2142 and is fixedly connected to the fixed ring 2121, and the telescopic connecting piece 2143 and the pushing shaft body 2142 are arranged at intervals on the same end of the moving plate 2141.

[0071] That is to say, when the rotating shaft section 2111 drives the adjusting assembly 212 to rotate and simultaneously drives the moving assembly 214 to rotate through the polygonal shaft body 2112, at this time, the adjusting ring surface 2122 can rotate within the fixed ring 2121. Furthermore, under the relative action of the undulating blocks on the pushing shaft body 2142 and the adjusting ring surface 2122, the telescopic connecting piece 2143 is compressed and rebounds, so that the moving plate 2141 drives the corresponding sawteeth to slide on the polygonal shaft body 2112, comprehensively stir the material on the feeding arc surface 2132, effectively avoid the accumulation of the material, and the moving directions of two adjacent moving assemblies 214 are opposite under the action of the adjusting assembly 212.

[0072] In this embodiment, the staggered feeding sawtooth unit 6 includes:

[0073] A plurality of row-type staggered sawtooth arrangement units 61 are annularly distributed, correspond to the side edges of the polygonal shaft body 2112, and the sawteeth of two adjacent row-type staggered sawtooth arrangement units 61 are arranged in a staggered manner;

[0074] A plurality of column-type staggered sawtooth arrangement units 62 are linearly distributed, and the sawteeth on adjacent column-type staggered sawtooth arrangement units 62 are distributed in a staggered manner. The sawteeth of the column-type staggered sawtooth arrangement units 62 are arranged between the sawteeth of the row-type staggered sawtooth arrangement units 61. Among the sawteeth in the same row, the sawteeth of the row-type staggered sawtooth arrangement units 61 are fixedly connected to the outer shaft sleeve 2113, the sawteeth of the column-type staggered sawtooth arrangement units 62 are fixedly connected to the moving assembly 214, are slidably connected to the outer shaft sleeve 2113, and the connection modes of the sawteeth in adjacent rows are opposite.

[0075] As a preferred embodiment, the polygonal shaft body 2112 is an octagonal shaft body, and there are eight moving components 214 annularly distributed, corresponding to the sides of the octagonal shaft body, and slidably arranged on the sides of the octagonal shaft body. That is, the staggered feeding sawtooth unit 6 includes eight rows of row-type staggered sawtooth arrangement units 61 and thirteen columns of column-type staggered sawtooth arrangement units 62. The row-type sawteeth are arranged horizontally and crosswise, and the width of the row-type sawteeth is 120 mm and the height is 255 mm; in the column-type staggered sawtooth arrangement unit 62, the single-column staggered sawteeth are arranged in the same way, and the double-column staggered sawteeth are arranged in the same way, and the width of the column-type sawteeth is 10 mm and the height is 255 mm.

[0076] Taking the upward side of the polygonal shaft body 2112 as an example, among the sawteeth in the same row, the sawteeth located on both sides are the sawteeth in the row-type staggered sawtooth arrangement unit 61. Then, the sawteeth of the row-type staggered sawtooth arrangement unit 61 here are fixed on the outer shaft sleeve 2113, and the sawteeth of the column-type staggered sawtooth arrangement unit 62 located between the sawteeth of the row-type staggered sawtooth arrangement unit 61 are fixed on the moving component 214 and slidably connected to the outer shaft sleeve 2113. Furthermore, on the adjacent side, the sawteeth located on both sides are the sawteeth in the column-type staggered sawtooth arrangement unit 62. Then, the sawteeth of the column-type staggered sawtooth arrangement unit 62 here are fixed on the outer shaft sleeve 2113, and the sawteeth of the row-type staggered sawtooth arrangement unit 61 located between the sawteeth of the column-type staggered sawtooth arrangement unit 62 are fixed on the moving component 214 and slidably connected to the outer shaft sleeve 2113. Furthermore, under the action of the adjusting component 212, the sawteeth fixed on the moving component 214 and in the same column move closer to the sawteeth fixed on the outer shaft sleeve 2113 on both sides respectively, and then reset, moving back and forth, so as to fully stir the materials between the sawteeth fixed on the outer shaft sleeve 2113, effectively avoiding the problem of material accumulation between the sawteeth.

[0077] In this embodiment, the offset fork-type sawtooth shaft sleeve unit 7 includes:

[0078] A shaft sleeve 71, fixed on the outside of the adjusting component 212;

[0079] A plurality of offset fork-type sawteeth 72 are annularly distributed, arranged at intervals with the shaft sleeve 71, and fixedly connected to the side sawteeth of the staggered feeding sawtooth unit 6.

[0080] As a preferred embodiment, the offset fork-type sawtooth shaft sleeve unit 7 includes eight rows of offset fork-type sawteeth 72. The offset fork-type sawteeth 72 are all spaced 20 mm from the shaft sleeve 71. The offset fork-type sawteeth 72 have a height of 90 mm and a width of 200 mm. The design of the offset fork-type sawtooth shaft sleeve unit 7 effectively avoids the occurrence of material accumulation and winding at both ends of the shaft.

[0081] In a specific implementation, under the continuous rotation of the three-stage material-dispensing device 2, the material in the material chamber 3 is moved by the upper material-dispensing section 21, the middle material-dispensing section 22 and the lower material-dispensing section 23, and is transported to the discharge platform 5 through the discharge port 4 at the bottom of the material chamber 3, and is transported to the combustion furnace by the discharge platform 5. When the material passes through the material-dispensing section, the material-dispensing shaft assembly 211 rotates, and at the same time drives the adjustment assembly 212 and the moving assembly 214 to rotate, thereby driving the saw teeth in the staggered material-dispensing sawtooth unit 6 and the offset fork-type sawtooth shaft sleeve unit 7 to rotate, and the material on the feeding arc surface 2132 is shifted, and the material on the feeding arc surface 2132 is moved by the material-dispensing shaft assembly 21 During the process of rotating to move the material, the adjusting ring surface 2122 rotates in the fixed ring 2121. Under the relative action of the pushing shaft 2142 and the undulating block on the adjusting ring surface 2122, the telescopic connecting member 2143 is compressed and rebounded, so that the moving plate 2141 drives the corresponding saw teeth to slide on the polygonal shaft 2112, that is, the saw teeth in the same row are respectively close to the saw teeth fixed on the outer sleeve 2113 on both sides, and reset, and move back and forth, so that the material between the saw teeth fixed on the outer sleeve 2113 is fully moved, and the material accumulation problem between the saw teeth is effectively avoided.

[0082] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
