Description

Technical Field

[0001] The invention belongs to the technical field of waste recycling, and in particular relates to a production line for processing biomass pellet fuel. Background Art

[0002] Biomass pellets are made by cold compacting and molding biomass straw, forestry waste and other raw materials through the pressure rollers and ring dies of the biomass pellet machine at room temperature. They are easy to transport and store, and are also beneficial to reducing the emission of greenhouse gas carbon dioxide and the consumption of primary energy.

[0003] However, the existing biomass pellet machines have the following problems during use:

[0004] Existing biomass pellets are generally squeezed by rollers on biomass straw and forestry waste in a ring die, and then the biomass material in the initial powder state is gradually pressed into biomass pellets of the required diameter through the evenly distributed holes on the ring die;

[0005] Although the existing ring die is made of rigid material, due to its own manufacturing characteristics, the outer wall of the ring die must be evenly distributed with biomass pellet forming holes. At the same time, during the production process, the roller constantly squeezes the biomass material and the ring die. The ring die is in the aforementioned uneven interaction force environment for a long time, and its outer wall is inevitably deformed and damaged to varying degrees, which causes the pore size of the biomass pellets in the ring die to change, affecting the final forming of the biomass pellet machine, and even clogging the ring die, which ultimately causes damage to the biomass pellet machine;

[0006] 2. When the ring die and the pressure roller are producing new and old biomass pellets, some of the old biomass pellets remain on the inner wall of the ring die aperture channel. Especially when the outer wall of the ring die is deformed, it is very easy for the old residues to affect the molding effect of the new biomass pellets, thereby affecting the processing efficiency of the biomass pellets and increasing the operating burden of the biomass pellet machine.

In the initial state, the outer wall of the flat column is tangent to the outer wall of the ring die.

[0050] The working method of the production line for biomass pellet fuel processing, the specific steps are as follows:

[0051] S1: First, through the linkage between the gears in the speed control unit, the control accuracy of the bearing base in the main unit is improved and the inertia generated during its operation is reduced, which is also conducive to increasing the output torque of the main motor;

[0052] S2: Then, the material plate gear and the top ring gear are meshed, so that the inner gear and the outer gear move relative to each other, and then the leveling column rotates while revolving, so as to repair the ring mold that moves relative to it after deformation;

[0053] S3: Finally, through the meshing effect between the annular gear and the linkage gear, the crank slider structure composed of the crank, the coupling plate and the sliding block is controlled to drive the cleaning seat to reciprocate on the fitting seat, and then the flexible brush head is continuously moved in and out of the shaping hole, so as to complete the cleaning operation of the residue in the shaping aperture.

[0054] The present invention has the following beneficial effects:

[0055] 1. The present invention uses a leveling column that is tangent to the outer wall of the ring die that has not been deformed in the initial state to assist in repairing the outer wall of the ring die that has been deformed during the operation, thereby improving the operating capacity and service life of the ring die in a long-term environment of different interaction forces. Specifically, the elastic force of the telescopic spring can be used to provide the leveling column with a reverse force for repairing the ring die until the ring die is tangent to the leveling column again. Through the coordinated cooperation of multiple leveling columns, the repair efficiency of the leveling column on the ring die is improved, thereby ensuring the production efficiency of the biomass pellet machine.

[0056] 2. The present invention controls the crank to drive the coupling plate to rotate through the meshing transmission between the annular gear and the linkage gear. At this time, the sliding block drives the cleaning seat to do reciprocating motion under the joint action of the coupling plate and the fitting seat, thereby enabling the elastic column to enter the corresponding shaping hole. In this process, the elastic action of the rubber column drives the flexible brush head to remove the residual biomass material in the shaping hole. The flexible brush head not only reduces the damage to the shaping hole, but also improves the freedom of movement of the brush head. At the same time, it also cooperates with the elastic action of the rubber column and the reciprocating motion of the cleaning seat to enhance the cleaning effect of the residue in the shaping aperture.

[0057] 3. The present invention uses the interaction between the elastic ball and the ring die to cause the outer wall of the ring die to vibrate slightly intermittently during operation, thereby assisting the flexible brush head in the dredging unit to loosen and remove the residual biomass material in the shaping hole of the ring die, which is beneficial to improving the cleaning degree of the shaping hole by the dredging unit, thereby improving the winding property of the ring die and indirectly increasing the service life of the biomass pellet machine.

[0078] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0079] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0080] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0081] Reference Figure 1 , Figure 4 and Figure 6 It can be seen that the production line for biomass pellet fuel processing includes a reduction box 1, which is divided into an upper part and a lower part, and the upper and lower parts are detachably installed by bolts, a speed regulating unit 2 is arranged inside the box, a main unit 3 is arranged at one side of the top of the box, a dredging unit 4 is arranged inside the main unit 3, a trimming unit 5 is arranged inside the main unit 3, and the trimming unit 5 is located outside the dredging unit 4;

[0082] Reference Figure 1 and Figure 2 It can be seen that a rectangular shielding seat 11 is provided at the bottom of the reduction box 1 for heat dissipation and moisture-proofing of the reduction box 1, a heat dissipation bracket 12 is provided at the middle position inside the lower half of the reduction box 1, a shock-absorbing plate 13 is provided at the junction of the upper and lower parts of the reduction box 1 away from the main unit 3, a bearing ring 14 is provided at the other side of the top of the reduction box 1, a main motor 15 that penetrates the reduction box 1 and is rotatably installed with the shock-absorbing plate 13 in the middle of the bearing ring 14, an external connecting frame 16 fixedly connected to the reduction box 1 is provided on the outer wall of the main motor 15 to assist the bearing ring 14 in limiting the freedom of the main motor 15, and a material receiving platform 17 is provided at one end of the reduction box 1 close to the main unit 3;

[0083] Reference Figure 2It can be seen that the speed regulating unit 2 includes: a main shaft 21, which is fixedly mounted on the output shaft end of the main motor 15 and is rotatably mounted with the heat dissipation bracket 12; a main gear 22, which is fixedly mounted on the outer wall of the main shaft 21; a primary gear 23, which is rotatably mounted on the end of the heat dissipation bracket 12 close to the main shaft 21 through a rotating shaft, and is meshed with the main gear 22; a reduction gear 24, which is coaxially mounted with the primary gear 23 and is at the bottom end of the primary gear 23; a secondary gear 25, which is rotatably mounted at the middle position of the heat dissipation bracket 12 through a rotating shaft, and is at the same horizontal height as the primary gear 23, but does not mesh with each other; a transmission gear 26, which is coaxially mounted with the secondary gear 25, and is at the bottom end of the secondary gear 25, and is meshed with the reduction gear 24; a sub-gear 27, which is arranged at one end of the heat dissipation bracket 12 away from the main shaft 21, and is at the same horizontal height as the secondary gear 25, and the two are meshed; a sub-shaft 28, which is rotatably mounted on the end of the heat dissipation bracket 12 away from the main shaft 21, and is coaxially fixedly connected with the sub-gear 27.

[0084] First, the protective seat 11 is used to prevent the reduction box 1 from directly contacting the bottom surface or other working surface (i.e., a space is reserved between the reduction box 1 and the working surface). On the one hand, it is beneficial to the heat dissipation of the reduction box 1, and improves the working stability of the speed regulating unit 2, the main unit 3, the dredging unit 4 and the trimming unit 5. On the other hand, it prevents the reduction box 1 from being corroded and damaged by moisture, and improves the service life of the reduction box 1.

[0085] Then, by the cooperation of the bearing ring 14 and the damping plate 13, the stability of the main motor 15 on the vertical working surface is improved, and the vibration effect of the main motor 15 on the speed regulating unit 2 is reduced. At the same time, by the installation of the external connecting frame 16, the operation stability and the convenience of later maintenance of the main motor 15 are improved; by laying the material receiving platform 17, a stable and feasible closed working space is provided for the discharge of the main unit 3, and by the spaced installation of the heat dissipation bracket 12 in the reduction box 1, it is further beneficial to the temperature control of the various components of the speed regulating unit 2 during operation;

[0086] Finally, the main gear 22 driven by the main shaft 21 causes the primary gear 23 to drive the reduction gear 24 to rotate synchronously. At this time, the transmission gear 26, under the meshing action of the reduction gear 24, synchronously drives the secondary gear 25 and the sub-gear 27 to engage with each other, and then the sub-shaft 28 synchronously follows the sub-gear 27 to rotate. That is, through the three-stage transmission between the aforementioned gears, it is beneficial to create a transmission operating environment with stable transmission, small vibration amplitude and low noise, and at the same time it is beneficial to increase the service life of the reduction box 1.

[0087] Reference Figure 1 , Figure 3 Figure 4It can be seen that the main unit 3 includes: a dust cover 31, which is detachably mounted on the top of the reduction box 1 near the material receiving platform 17 by bolts; a heat conducting component 32, which is composed of two cylindrical parts of different diameters and is arranged inside the dust cover 31, and a part of the structure passes through the dust cover 31 and is connected to the outside; a granulating chamber 33, which is detachably mounted on the end of the dust cover 31 away from the reduction box 1 by a connecting plate and bolts, and the granulating chamber 33 has an upper part and a lower part, and the upper and lower parts are also connected by bolts; a discharge port 34, which is fixedly mounted on the lower half of the granulating chamber 33, and is close to the middle position of the outer wall on one side of the material receiving platform 17; a material dial motor 35, which is fixedly mounted on the lower half of the granulating chamber 33 through a mounting seat, and is away from the middle position of the outer wall on one side of the material receiving platform 17;

[0088] The top cover 36 is mounted on the top of the granulating chamber 33; the top ring gear 37 is rotatably mounted on the bottom wall of the top cover 36; the feed tray gear 38 is rotatably mounted on the upper half of the granulating chamber 33 through a rotating shaft, and is fixedly connected to the output shaft of the feed tray motor 35, and is meshed with the top ring gear 37; the bearing base 39 is fixedly mounted on the top of the secondary shaft 28, and penetrates the top of the reduction box 1 and is coaxially mounted with the dust cover 31;

[0089] Reference Figure 4 and Figure 8 It can be seen that a connecting rod 381 is evenly arranged at the bottom end of the top ring gear 37, an internal gear 382 is installed at the middle position of the outer wall of the connecting rod 381, and the outer wall of the lower end of the connecting rod 381 is fixedly connected to the sleeve rod 51, and an external gear 383 meshing with the internal gear 382 is installed on the inner wall of the upper half of the granulation chamber 33, and a guide ring 384 is commonly arranged at the junction of the upper and lower parts of the granulation chamber 33, and a ring die 385 is installed on the top of the bearing base 39, and shaping holes 386 are evenly opened on the outer wall of the ring die 385; a cross rod 361 is installed through the middle position of the top cover 36, and a cross plate 362 is fixedly installed at one end of the cross rod 361 close to the reduction box 1, and a pressure roller 363 is symmetrically installed on the bottom surface of the cross plate 362, and the pressure roller 363 is a through groove type.

[0090] When the speed regulating unit 2 completes the speed regulation (at this time, the countershaft 28 drives the bearing base 39 to rotate synchronously under the action of the counter gear 27):

[0091] The ring die 385 rotates synchronously with the bearing base 39. At the same time, the material plate gear 38, under the action of the material plate motor 35, synchronously drives the top ring gear 37 meshing with it to rotate. Then, the connecting rod 381, under the action of the top ring gear 37, synchronously drives the internal gear 382 to rotate (the internal gear 382 continuously moves relative to the external gear 383 at different positions during the rotation process, and promotes the intermittent rotation of the external gear 383). The guide ring 384 provides a stable auxiliary guide for the connecting rod 381 during the movement, so as to avoid vibration of the connecting rod 381 during the movement that destroys the precise meshing of the internal gear 382 and the external gear 383.

[0092] When biomass straw or forestry waste is introduced into the ring die 385 through an external conduit (at this time, the ring die 385 rotates synchronously under the action of the bearing base 39):

[0093] The cross bar 361 drives the cross plate 362 and the pressure roller 363 thereon to move inside the ring die 385 in the opposite direction to the rotation direction of the ring die 385, and through the mutual extrusion between the pressure roller 363 (and the through-groove type pressure roller 363 can effectively relieve the pressure inside the granulation chamber 33, reduce the damage of the pressure roller 363 and the ring die 385, and improve the winding performance and stability of both) and the ring die 385, the cross bar 361 can be driven to rotate by an external motor, so that the biomass straw and forestry waste pass through the shaping hole 386 until they are pressed into biomass particles, and finally flow to the receiving platform 17 through the discharge port 34;

[0094] In this process, the dust cover 31 is set to prevent the dust generated during the operation of the pressure roller 363 and the ring die 385 from flowing to the outside in large quantities, cut off the contact channel with the operators, and reduce the probability of the operators suffering from pneumoconiosis. At the same time, the excessive temperature and pressure in the granulation chamber 33 are assisted to be cleared through the heat conduction component 32 (in specific implementation: the opening and closing of the heat conduction component 32 and the external flow channel can be controlled by an external one-way valve) to ensure the stable operation of the biomass pellet machine.

[0095] Reference Figure 5 and Figure 6It can be seen that the dredging unit 4 includes: two fitting seats 41, which are symmetrically slidably arranged on the inner wall of the ring mold 385, and the fitting seats 41 are evenly distributed with holes consistent with the shaping holes 386 on the vertical section; the ring gear 42 is fixedly installed in the middle position of the top of the ring mold 385; the linkage gear 43 is rotatably installed on the top horizontal section of each fitting seat 41 through a rotating shaft, and meshes with the ring gear 42; the crank 44 is rotatably installed in the middle position of the top of each linkage gear 43; the coupling plate 45 is rotatably installed on the end of the crank 44 away from the linkage gear 43; the sliding block 46 is rotatably installed on the end of the coupling plate 45 away from the linkage gear 43 through a rotating shaft, and is slidably installed between the horizontal section of the fitting seat 41; the cleaning seat 47 is slidably installed on the vertical section of the fitting seat 41, and is fixedly connected to the sliding block 46 through a pin shaft;

[0096] Reference Figure 6 and Figure 7 It can be seen that elastic columns 471 are evenly arranged on the end face of the vertical section of the cleaning seat 47 close to the inner wall of the ring die 385, and the position distribution of the elastic columns 471 is completely consistent with the position distribution of the shaping holes 386. At the same time, the diameter of the elastic columns 471 is smaller than the diameter of the shaping holes 386, and its length is greater than the sum of the thickness of the inner and outer walls of the ring die 385 and the thickness of the vertical section of the fitting seat 41. Rubber columns 472 are evenly installed on the outer wall of each elastic column 471, and a flexible brush head 473 is installed at one end of the rubber column 472 away from the axis of the elastic column 471, and the cross-section of the flexible brush head 473 is an isosceles trapezoid.

[0097] When the ring die 385 rotates:

[0098] At this time, the ring gear 42 drives the linkage gear 43 to rotate under the action of the ring mold 385, and then controls the crank 44 to drive the coupling plate 45 to rotate, and the sliding block 46 drives the cleaning seat 47 under the action of the coupling plate 45 to perform stable reciprocating motion under the stable guidance of the fitting seat 41;

[0099] At the same time, the evenly distributed elastic columns 471 follow the movement of the cleaning seat 47, intermittently reciprocate into or out of the shaping hole 386, and fully and effectively remove the residual biomass material in the shaping hole 386 through the flexible brush head 473 (in the dynamic process of the flexible brush head 473 entering and exiting the shaping hole 386, the elastic force of the rubber column 472 and the elastic column 471 releases the contact freedom of the flexible brush head 473, so that the flexible brush head 473 can fully contact the residues at various positions in the shaping hole 386, which is beneficial to enhance the cleaning ability of the flexible brush head 473. At the same time, the material limitations of the elastic column 471, the rubber column 472 and the flexible brush head 473 prevent the ring mold 385 from being damaged by the overly rigid material and the ring mold 385 when it is deformed, resulting in an increase in production costs);

[0100] In the specific implementation process, the speed of the ring mold 385, the module of the ring gear 42 and the linkage gear 43, and the running trajectory of the crank 44 slider structure composed of the crank 44, the coupling plate 45 and the sliding block 46 can be calculated to achieve coordination and unity among the three, thereby achieving targeted coordination between the flexible brush head 473 and the shaping hole 386.

[0101] Reference Fig. 9 , Fig.10 and Fig.11 It can be seen that the trimming unit 5 includes: three sleeve rods 51, which are evenly arranged inside the main unit 3; four receiving bins 52, which are evenly arranged on the outer wall of each sleeve rod 51; a baffle 53, which is fixedly installed at one end of each receiving bin 52 close to the axis of the sleeve rod 51; a partition 54, which is slidably installed at one end of each receiving bin 52 away from the axis of the sleeve rod 51; three movable columns, which are evenly distributed inside each receiving bin 52, are both slidably installed with the baffle 53 and fixedly installed with the partition 54;

[0102] Leveling column 56, four groups of movable columns are distributed on each sleeve rod 51, among which three groups of movable columns are provided with leveling column 56, and the leveling column 56 is fixedly installed at one end of the movable column away from the axis of the sleeve rod 51, and the outer wall of the leveling column 56 is sleeved with a rubber layer; two sealing rings 57 are set in a group, symmetrically arranged on the opposite surfaces of the baffle and the partition 54, and slidably installed with the outer wall of the movable column; telescopic spring 58 is sleeved on the outer wall of the movable column between the opposite surfaces of the baffle and the partition 54; elastic ball 59 is evenly arranged at one end of another group of movable columns away from the axis of the sleeve rod 51 through a clamping seat and an elastic line;

[0103] As can be seen from reference 8, the top of the ring die 385 is lower than the bottom of the guide ring 384, and there is a cross solid distribution band on the outer wall of the ring die 385 to strengthen the structural strength of the ring die 385. The outer wall of the flat column 56 in the initial state is tangent to the outer wall of the ring die 385.

[0104] When the connecting rod 381 rotates synchronously with the top ring gear 37:

[0105] At this time, the inner gear 382 at different positions continuously moves relative to the outer gear 383 during rotation, and then the sleeve rod 51 drives the accommodating chamber 52 to rotate under the action of the outer gear 383. During this process, the leveling column 56 (the rubber layer on the outside of the leveling column 56 prevents the leveling column 56 made of rigid material from directly contacting the outer wall of the ring die 385, reduces the probability of secondary damage to the ring die 385, and improves the repair integrity of the deformed outer wall of the ring die 385 by the leveling column 56) continuously contacts and squeezes the outer wall of the ring die 385 (only for the deformed ring die 385), and through the elastic force of the telescopic spring 58, provides strong support for the repair of the leveling column 56, and releases the degree of freedom of the leveling column 56, thereby improving the repair practicability of the leveling column 56 (avoiding the leveling column 56 in a fixed position, because the leveling column 56 in a fixed position can only repair one type of ring die 385, which causes certain limitations on its operating range);

[0106] The partition plate 54 improves the movement stability of the movable shaft 55 and the leveling column 56 in the accommodation chamber 52, which is conducive to improving the stable repair of the ring die 385 by the leveling column 56 and reducing the probability of the ring die 385 being damaged again;

[0107] Through the interaction between the elastic ball 59 and the ring die 385, the outer wall of the ring die 385 vibrates slightly intermittently during operation, thereby assisting the flexible brush head 473 in the dredging unit 4 to loosen and remove the residual biomass material in the shaping hole 386 of the ring die 385.

[0108] The working principle of the biomass pellet fuel processing production line provided by the present invention is as follows: Step 1: First, the main gear 22 and the primary gear 23 are meshed and driven, so that the transmission effect between the reduction gear 24 and the transmission gear 26 is realized between the secondary gear 25 and the auxiliary gear 27, and then the bearing base 39 drives the ring die 385 to rotate;

[0109] Step 2: Then, the material tray gear 38 and the top ring gear 37 are meshed, so that the inner gear 382 and the outer gear 383 move relative to each other, and then the leveling column 56 rotates while revolving, so as to repair the ring mold 385 that moves relative to it after deformation;

[0110] Step 3: Finally, through the meshing effect between the annular gear 42 and the linkage gear 43, the crank 44 slider structure composed of the crank 44, the coupling plate 45 and the sliding block 46 is controlled to drive the cleaning seat 47 to reciprocate on the fitting seat 41, and then the flexible brush head 473 is continuously entered and exited from the shaping hole 386, so as to complete the cleaning operation of the residue in the aperture of the shaping hole 386.

[0111] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0112] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
