Description

Technical Field

[0001] The invention relates to the technical field of biomass pellet fuel, in particular to a biomass pellet fuel rapid prototyping machine. Background Art

[0002] Biomass briquette fuel uses agricultural and forestry waste as raw materials, and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned. Biomass briquette fuel is mostly a block fuel produced by processing stem crops, peanut shells, bark, sawdust, and solid waste (furfural residue, edible fungus residue, etc.). Its advantage is that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters. The complete set of equipment for biomass briquette fuel molding processing includes a feeding system, a molding system, a discharging system, and a power distribution system. The main production equipment from raw materials to products includes loaders, crushers, conveyor belts, briquetting machines, granulators, dryers, packaging machines, etc.

[0003] After searching, the patent publication number CN218047796U discloses a patent named "biomass briquetting pellet integrated machine". The technical problem to be solved is that the crushed biomass straw, forestry waste and other raw materials still contain some raw materials that are not completely crushed. They need to be filtered and screened separately before being injected into the pellet forming machine. This leads to low efficiency of biomass briquetting pellet forming and fails to achieve the effect of integrated production. By adding a raw material filtering device on the basis of the biomass briquetting pellet forming machine, the continuous rotation of two sets of extrusion rollers can synchronously drive three sets of first baffles and three sets of second baffles distributed at equal angles to rotate synchronously. , and the first baffle and the second baffle plate squeeze the filter plate, so that the filter plate can perform reciprocating lifting and sliding in the vertical direction inside the molding bin, and when the squeezing roller rotates at a sufficient rate, the filter plate will produce an up and down vibration effect, thereby accelerating the screening of the raw materials, and the screened raw materials will quickly roll into the two groups of storage boxes for collection, the filtration efficiency is high, and the effect of integrated particle molding is achieved; but there are still the following drawbacks that need to be solved: part of the raw material powder agglomerates and remains inside the granulation hole, resulting in the exported biomass fuel particles being incomplete and unqualified, and affecting the subsequent production of biomass fuel particles.

[0027] In the present invention, a material filter assembly is placed inside the feed hopper 2, and the material filter assembly is composed of a filter cover 3 and an expansion frame 4. The outer side of the bottom end of the filter cover 3 is fixedly connected to the expansion frame 4. The feed hopper 2 is partially located at the top of the body 1. The material filter assembly is composed of the filter cover 3 and the expansion frame 4. The introduced biomass raw material particles can be screened, and the large particles therein can be intercepted to avoid affecting the molding effect of the biomass particle fuel, and the biomass particle fuel can be evenly introduced into the body 1.

[0028] A driving motor 10 is fixedly installed on the upper end of the outer wall of the other end of the body 1, and a driving bevel gear 11 is fixedly installed on the output end of the driving motor 10.

[0029] A shunt pipe 15 is fixedly connected to the middle of the bottom end of the flow guide pipe 14, and a flow regulating valve 16 is arranged on the outer side of the circumference of the shunt pipe 15.

[0030] Each group of the first cleaning pipe 25 and the second cleaning pipe 26 are both located on the outside of the bottom end of the aggregate cover 20 and the outside of the top end of the isolation cover 24, and each group of the first cleaning pipe 25 and the second cleaning pipe 26 are both located on the outside of the circumference of the first forming roller 17 or the second forming roller 18. A plurality of nozzles 30 with equal distances are fixedly installed on the circumference of the first cleaning pipe 25 and the second cleaning pipe 26, and each nozzle 30 is perpendicular to the first forming roller 17 and the second forming roller 18, and the outlet end of each nozzle 30 is rectangular. The first forming roller 17 and the second forming roller 18 are cleaned by the plurality of nozzles 30 of the first cleaning pipe 25 and the second cleaning pipe 26 of the two groups. The forming roller 18 sprays high-pressure airflow around its circumference, and the airflow sprayed from the first cleaning pipe 25 quickly impacts the outer circumferential walls of the first forming roller 17 and the second forming roller 18 and the inside of the forming groove, so that the biomass raw material particles bonded thereto are cracked, reduced in size, and fall off. Then, the airflow sprayed from the second cleaning pipe 26 quickly impacts the outer circumferential walls of the first forming roller 17 and the second forming roller 18 and the inside of the forming groove again, flushing away the remaining biomass raw material particles under high pressure. The biomass raw material residues after the two impacts fall on the top of the isolation cover 24, and are introduced from the slag discharge port 6 into the storage bag sleeved by the plug-in 8, where they are collected and recycled.

[0031] The two sides of the aggregate cover 20 are in the shape of an inner concave arc, and the aggregate cover 20 is wide at the top and narrow at the bottom. The outlet end of the aggregate cover 20 is located at the top between the first forming roller 17 and the second forming roller 18, and the bottom end of the aggregate cover 20 is in contact with the circumferential outer wall of the first forming roller 17 and the second forming roller 18. The screened biomass raw material particles are introduced into the body 1 through the feed hopper 2, and the biomass raw material particles are first diverted and guided to the middle and upper ends of both sides of the aggregate cover 20 by the distribution table 21. The biomass particle fuel is guided from the bottom end of the aggregate cover 20 to the top between the first forming roller 17 and the second forming roller 18, and then the biomass raw material particles are extruded and formed, and the vibration motor 23 works at the bottom end of the distribution table 21, and its vibration helps the biomass raw material particles fall from the top of the distribution table 21 and both sides of the aggregate cover 20;

[0032] The material distribution platform 21 is inverted V-shaped, and a support plate 22 is fixedly installed on the upper ends of the inner walls on both sides of the bottom end of the material distribution platform 21, and a vibration motor 23 is fixedly installed on the top of the support plate 22;

[0033] The isolation cover 24 is in a concave arc shape, and the top ends of the two isolation covers 24 are respectively attached to the first forming roller 17 and the second forming roller 18;

[0034] The lower ends of the outer walls on both sides of the machine body 1 are fixedly installed with an insertion frame 7, and the slag discharge port 6 is located on the inner side of the insertion frame 7. A plug-in 8 is slidably inserted inside the insertion frame 7, and a storage bag is sleeved inside the plug-in 8. By sliding the plug-in 8 and the insertion frame 7, the storage bag for collecting biomass raw material slag can be replaced in time;

[0035] An air cavity 28 is formed between the bottom end of the discharge plate 27 and the bottom end of the machine body 1 , and the discharge plate 27 is provided with a plurality of inclined air holes 29 at equal distances.

[0036] Working principle: The bottom of the material collecting cover 20 is attached to the circumferential outer wall of the first forming roller 17 and the second forming roller 18, and the tops of the two isolation covers 24 are attached to the first forming roller 17 and the second forming roller 18 respectively. The screened biomass raw material particles are introduced into the body 1 through the feed hopper 2. The biomass raw material particles are first diverted and directed to the middle and upper ends of both sides of the material collecting cover 20 by the material dividing table 21. The biomass particle fuel is guided from the bottom of the material collecting cover 20 to the top between the first forming roller 17 and the second forming roller 18. The driving motor 10 works to make the rotating active bevel gear 11 drive the driven bevel gear 32 to rotate, thereby rotating the second forming roller 18. At the same time, the first forming roller 17 is rotated through the meshing of the two transmission gears 19, so that the first forming roller 17 and the second forming roller 18 are simultaneously The effect of the opposite rotation is to extrude and form the biomass raw material particles. Since each nozzle 30 is perpendicular to the first forming roller 17 and the second forming roller 18, and the outlet end of each nozzle 30 is rectangular, the airflow ejected from the first cleaning pipe 25 quickly impacts the outer circumference wall of the first forming roller 17 and the second forming roller 18 and the inside of the forming groove, so that the bonded biomass raw material particles are cracked, reduced in size and fall off. Then the airflow ejected from the second cleaning pipe 26 quickly impacts the outer circumference wall of the first forming roller 17 and the second forming roller 18 and the inside of the forming groove again, and the remaining biomass raw material particles are washed away with high pressure. The biomass raw material residues after the two impacts fall on the top of the isolation cover 24, and are introduced from the slag discharge port 6 into the storage bag sleeved by the plug-in 8, and are collected and recycled.

[0037] The gas outlet of the shunt pipe 15 is controlled by the flow regulating valve 16, and the high-pressure gas discharged from the shunt pipe 15 is distributed inside the air cavity 28, and the gas is discharged from the multiple inclined air holes 29 of the discharge plate 27, which not only helps to promote the discharge of biomass fuel particles, but also takes away the heat emitted by the biomass fuel particles in time, so that the biomass fuel particles can be bagged after being discharged and collected, without worrying about the potential safety hazards caused by the accumulation of heat due to the accumulation of biomass fuel particles.
