Description

Technical Field

[0001] The present invention relates to the technical field of particle processing, and in particular to a biomass fuel particle processing device. Background Art

[0002] In the related technology, biomass combustion pellets are block or granular fuels made from agricultural waste or forestry residues through physical compression. The core component is biomass energy, which is softened and bonded by lignin under high temperature and high pressure to form a high-density, low-water content solid fuel. In the biomass fuel pellet industry, due to fierce market competition, cost control has always been the key.

[0003] In the prior art, when extruding biomass fuel pellets, most of the time, the pressure roller and the ring die are selected to work together: after the raw materials enter the pellet machine, the pressure roller rotates under power drive, and squeezes the material into the die hole of the ring die. The high temperature generated by friction softens the lignin and bonds the material to form dense pellets. Usually, when the pellets are extruded, the scraper that moves relative to the ring die will shovel off the pellet strips. However, the existing scraper does not cut off the pellet strips when it contacts them. The uniform relative movement of the scraper and the ring die causes the pellet strips to be broken laterally instead of being cut accurately. In addition, the pellet debris continues to accumulate on the scraper surface to form a gelatinization layer, which directly reduces the sharpness of the blade, resulting in serious damage to the end face of the finished pellets. A large amount of pellet debris is generated when breaking, which reduces the quality of the finished product and increases the processing cost. At the same time, the pellets with rough fracture surfaces are easy to break during transportation; therefore, it does not meet the existing needs. In this regard, we propose a biomass fuel pellet processing device. Summary of the invention

[0004] The present invention provides a biomass fuel particle processing device, which can allow a scraper to automatically switch states, actively cut particle strips, shrink and hide to keep sharp when not cutting, thereby improving the shear force on the particle strips, improving the quality of the finished product and reducing the processing cost. It solves the problem mentioned in the above background technology that the existing scraper does not cut off the particle strips when it contacts the particle strips, resulting in serious damage to the cross-section of the finished particle, and a large amount of particle debris is generated when it is broken, which reduces the quality of the finished product and increases the processing cost.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and easy to understand, the specific implementation methods of the present disclosure are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure. However, the present disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present disclosure, so the present disclosure is not limited by the specific embodiments disclosed below.

[0031] In the description of the present disclosure, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure. The terms "first" and "second" are used to distinguish one element from another, and do not have order or importance. In addition, when the following description refers to the drawings, the same figure numbers in different drawings represent the same or similar elements, which are not elaborated in the present disclosure.

[0032] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0033] According to some embodiments of the present disclosure, a biomass fuel particle processing device is provided, referring to Figure 1-Figure 10 As shown in, the biomass fuel particle processing device includes a casing 10, a fixed disk 150 is fixedly arranged on the top of the casing 10, a center frame 120 is rotatably mounted on the fixed disk 150, a plurality of pressure rollers 130 are rotatably mounted on the center frame 120, a ring die 110 is arranged on the fixed disk 150, a plurality of partition blocks 112 are arranged in a circular array on the outer side of the ring die 110, a plurality of scabbards 220 are connected to the outer side of the center frame 120, a cutting knife 210 for cutting particle strips is slidably mounted on the scabbard 220, a trigger block 260 is slidably mounted on the side of the scabbard 220, a knife outlet assembly is arranged inside the scabbard 220, when the trigger block 260 conflicts with the partition block 112, the knife outlet assembly drives the cutting knife 210 to extend quickly and cut the particle strip, and an energy storage mechanism is also arranged in the knife outlet assembly to increase the instantaneous shear force of the cutting knife 210.

[0034] During the rotation of the scabbard 220, the cutting knife 210 has two states. In the first state, the scabbard 220 is located between two partition blocks 112. At this time, the trigger block 260 is relaxed and does not contact the partition block 112. Therefore, in the first state, the cutting knife 210 is retracted in the scabbard 220. In the second state, the trigger block 260 conflicts with one of the partition blocks 112. At this time, the knife-out assembly is triggered. Therefore, in the second state, the cutting knife 210 extends to cut the particles.

[0035] In this way, the cutting knife 210 is normally hidden in the scabbard 220, so the knife tip is not easily stuck by debris, thereby maintaining sharpness, making the particle cross section smoother, improving the qualified rate of biomass fuel particle products, reducing the generation of debris, and reducing processing costs.

[0036] In addition, in combination with the prior art, a reduction motor 20 is installed at the bottom of the casing 10, and the output shaft of the reduction motor 20 is connected to the center frame 120. A drive motor 140 is installed on the center frame 120, and the drive motor 140 is transmission-connected to the pressure roller 130. A dust cover 40 is fixedly installed on the fixed plate 150, and a feed port 30 is installed on one side of the dust cover 40, and a discharge port 50 is provided on the other side of the dust cover 40. The difference is that a connecting arm 250 is connected between the center frame 120 and the scabbard 220.

[0037] Furthermore, a dust plate 240 is installed on the side of the scabbard 220 adjacent to the ring die 110, and the dust plate 240 is slidably fitted with the outer wall of the ring die 110. A push plate 230 is installed on the end of the scabbard 220 away from the cutting knife 210 to push the cut particles. The dust plate 240 slides closely against the outer wall of the ring die 110 to prevent debris from entering the scabbard 220; the push plate 230 pushes the finished particles out after cutting to prevent accumulation and blockage.

[0038] Specifically, see Figure 3 The ring die 110 is provided with a plurality of die holes 111, which are located between two adjacent partition blocks 112 and in the middle of the ring die 110. The die holes 111 avoid the positions of the dustproof plate 240 and the trigger block 260.

[0039] Through the above technical scheme, when the biomass fuel particle processing device provided by the present invention is in use, a partition block 112 is set on the outside of the ring mold 110, and a cutting knife 210 and a scabbard 220 are set, so that when the center frame 120 rotates, the scabbard 220 and the partition block 112 rotate relative to each other, so that the trigger block 260 periodically conflicts with the partition block 112, and the cutting knife 210 is automatically extended for cutting by the transmission of the knife-out assembly. Compared with the traditional technology, the cutting knife 210 in this scheme is normally hidden in the scabbard 220, so the knife end is not easily stuck by the debris, thereby keeping it sharp, and when the cutting knife 210 is extended, it no longer cuts at a uniform speed. The instantaneous shear force can be increased by energy storage release, the particles are better cut off, and the particle cross-section is smoother, which further improves the qualified rate of biomass fuel particles, reduces the generation of debris, and reduces the processing cost.

[0040] It should be noted that the cutting knife 210 and the scabbard 220 are both arranged in an arc shape, the reduction motor 20 and the driving motor 140 are both existing products, the output shaft of the driving motor 140 is equipped with gears, and the plurality of pressure rollers 130 are also respectively equipped with gears, and the driving motor 140 is connected to the pressure rollers 130 through gears. In addition, a belt can also be selected for transmission. The setting of the pressure roller 130 is an existing technology and will not be described in detail here.

[0041] In some embodiments, a knife assembly is provided inside the scabbard 220. When the trigger block 260 contacts the partition block 112, the knife assembly drives the cutting knife 210 to extend quickly and cut the particle strip. Figure 6 As shown in , the knife ejection assembly includes a first chamber 330 and a second chamber 350 opened inside the scabbard 220, a driving piston 320 is slidably installed inside the first chamber 330, a bevel column 310 is connected to the top of the driving piston 320, the bevel of the bevel column 310 is in contact with the trigger block 260, a knife ejection spring 340 is installed between the bottom of the driving piston 320 and the first chamber 330, a knife ejection piston 360 is connected to the end of the cutting knife 210, the knife ejection piston 360 is slidably installed in the second chamber 350, and the second chamber 350 is connected to the first chamber 330.

[0042] When the trigger block 260 is squeezed, the trigger block 260 moves the squeezing ramp column 310, causing the driving piston 320 to move downward, compressing the gas in the first chamber 330, causing the gas to enter the second chamber 350, thereby pushing the knife piston 360 to move, thereby realizing the action of extending the cutting knife 210 out of the scabbard 220.

[0043] In this embodiment, in order to solve the problem that the end surface of the particle forms burrs and cracks due to uneven force and the roughness increases significantly due to the lack of instantaneous shear force, Figure 7The energy storage mechanism is configured as follows: a ramp block 450 is installed on the side of the trigger block 260, an air receiving seat 410 is connected to the side of the second chamber 350, one side of the air receiving seat 410 is the first chamber 330, the other side of the air receiving seat 410 is connected to an air pipe 370, the other end of the air pipe 370 is connected to the second chamber 350, a valve plate 420 is slidably installed in the middle of the air receiving seat 410, a vent hole 430 is opened on the valve plate 420, and a pressure spring 440 is installed at the bottom of the valve plate 420.

[0044] The inclined surface block 450 intermittently contacts the valve plate 420 . When the inclined surface block 450 contacts the valve plate 420 , the pressure spring 440 is compressed, and the vent hole 430 is communicated with the air pipe 370 and the first chamber 330 .

[0045] In order to increase the instantaneous shear force, a valve plate 420 is arranged at the air receiving seat 410. When the trigger block 260 is not triggered and in the early stage of triggering, the inclined block 450 on the trigger block 260 does not contact the top of the valve plate 420. Therefore, the valve plate 420 is lifted up by the pressure spring 440, so that the solid part of the valve plate 420 blocks the air hole of the air receiving seat 410, thereby preventing the gas from entering the second chamber 350 and continuing to be compressed; in the later stage of triggering the trigger block 260, the inclined block 450 contacts the top of the valve plate 420, so that the valve plate 420 moves downward, and the air vent 430 is connected with both sides, so that the compressed gas quickly enters the second chamber 350, so that the cutting knife 210 can be unsheathed more quickly.

[0046] In other embodiments, a knife assembly is provided inside the scabbard 220. When the trigger block 260 contacts the partition block 112, the knife assembly drives the cutting knife 210 to extend quickly and cut the particle strip. Figure 8 As shown in the figure, the knife-discharging assembly includes a rotating sleeve 321 and a rotating shaft 351 rotatably mounted inside the scabbard 220, a contact plate 311 is integrally arranged on the rotating sleeve 321, the contact plate 311 contacts the trigger block 260, a first bevel gear 331 is fixedly mounted on the end of the rotating sleeve 321, a second bevel gear 341 is fixedly mounted on the rotating shaft 351, the second bevel gear 341 meshes with the first bevel gear 331, a transmission gear 361 is symmetrically mounted on the rotating shaft 351, a rack plate 371 is arranged on the cutting knife 210, and the transmission gear 361 meshes with the rack plate 371.

[0047] Specifically, a torsion spring is installed at one end of the rotating sleeve 321 away from the first bevel gear 331 , and the other end of the torsion spring is connected to the inner wall of the scabbard 220 for resetting.

[0048] When the trigger block 260 is squeezed, the trigger block 260 squeezes the contact plate 311 to rotate the rotating sleeve 321, so that the first bevel gear 331 drives the second bevel gear 341 to rotate, and the rack plate 371 moves, so that the cutting knife 210 is automatically unsheathed.

[0049] In this embodiment, in order to solve the problem that the end surface of the particle forms burrs and cracks due to uneven force and the roughness increases significantly due to the lack of instantaneous shear force, Fig. 9 The energy storage mechanism is configured as follows: a sleeve plate 421 is fixedly mounted on the top of the cutting knife 210, a movable plate 411 is fixedly mounted on the bottom of the rack plate 371, an empty slot 431 is opened inside the sleeve plate 421, the movable plate 411 is slidably plugged into the empty slot 431, a return spring 441 is installed between the movable plate 411 and the empty slot 431, a blocking block 461 is slidably mounted on the inner wall of the scabbard 220, the blocking block 461 is configured as a sliding block with an inclined surface at one end and a blocking spring 471 installed at the other end, fixed columns 451 are fixedly mounted on both sides of the sleeve plate 421, and the blocking block 461 intermittently conflicts with the fixed column 451.

[0050] The inner wall of the scabbard 220 is provided with a slide groove, the blocking block 461 is slidably installed in the slide groove, the blocking spring 471 is also installed in the slide groove, and the bevel tip of the blocking block 461 is rounded, and the fixed column 451 is set as a high-temperature resistant rubber column with a dome at the end. After the fixed column 451 and the blocking block 461 are in conflict to a certain extent, the fixed column 451 breaks through the blocking block 461, so that the cutting knife 210 is instantly unsheathed from the scabbard 220 to cut the strips of particles. When resetting, due to the conflict between the fixed column 451 and the bevel of the blocking block 461, the blocking block 461 naturally retracts and does not block the resetting.

[0051] In order to better cut the particles, a movable plate 411 and a sleeve plate 421 are added between the rack plate 371 and the cutting knife 210. In the early stage of the operation of the knife output assembly in this embodiment, the fixed column 451 is blocked by the blocking block 461, so that the movable plate 411 moves into the sleeve plate 421, but the sleeve plate 421 does not move. Energy is compressed and stored in the early stage of the stroke. In the later stage of the operation of the knife output assembly, the fixed column 451 breaks through the blocking block 461. The release of elastic potential energy makes the cutting knife 210 unsheathed more quickly, thereby increasing the instantaneous shear force.

[0052] The instantaneous shear force of the cutting blade 210 is significantly improved, so that the biomass combustion particles are subjected to more uniform force, the cut is smooth, the debris and dust generated by cutting are reduced, the quality of the finished product is improved, and the processing cost is reduced.

[0053] In some embodiments of the present disclosure, reference Figure 10-12As shown in , a screening ring 160 is installed on the outside of the fixed plate 150 by bolts, and the screening ring 160 is arranged as a circular track with a plurality of screening holes, and a spiral elastic slide 610 is installed below the screening ring 160, and the width of the spiral elastic slide 610 corresponds to the screening ring 160, and flexible cloth covers 630 are installed on both sides of the spiral elastic slide 610, and the top of the flexible cloth cover 630 is fixedly connected to the bottom of the screening ring 160, and the end of the spiral elastic slide 610 is connected to the slag outlet 60, and an elastic cloth 620 is installed at the connection between the spiral elastic slide 610 and the slag outlet 60, and the top of the elastic cloth 620 is connected to the bottom of the screening ring 160.

[0054] Among them, a turntable 510 is rotatably installed on the top of the casing 10, a striking wheel 520 is rotatably installed on the side of the turntable 510, a fixing rod 530 is fixedly installed on the side of the fixing plate 150, a vibration block 560 is fixedly installed on the bottom of the screening ring 160, a knocking hammer 540 is rotatably installed on the fixing rod 530, the knocking hammer 540 is in contact with the vibration block 560, and a torsion spring 550 for storing force and resetting is installed on the fixing rod 530, and both ends of the torsion spring 550 are respectively engaged with the knocking hammer 540 and the fixing plate 150.

[0055] Specifically, after the torsion spring 550 accumulates force, it drives the striking hammer 540 to periodically strike the screening ring 160 to prevent the screen holes from being blocked.

[0056] Furthermore, the elastic cloth 620 is configured as a rubber band or other heat-resistant elastic cloth to increase the shaking of the spiral elastic slide 610. The flexible cloth cover 630 is configured as a dustproof elastic cloth or plastic cloth, which can shake with the spiral elastic slide 610 and cover the dust.

[0057] Through the above technical solution, when the biomass fuel particle processing device provided by the present disclosure is in use, the reduction motor 20 rotates with the turntable 510, and when the striking wheel 520 on the turntable 510 contacts the knocking hammer 540 on the fixed plate 150, the torsion spring 550 is charged, and when the striking wheel 520 and the knocking hammer 540 are offset, the torsion spring 550 is released to drive the knocking hammer 540 to hit the vibration block 560, and the vibration block 560 transmits the vibration energy to the screening ring 160 through a rigid connection, so that the screening ring 160 generates high-frequency vibration, so that the debris powder on the screening ring 160 falls onto the spiral elastic slide 610 and slides out from the slag outlet 60.
