The pressurizing machine 54 is fixed on the bearing frame 1 and is connected with the pressurizing ring pipe 52 through a pipeline. Under the action of the air blowing mechanism 2, the air flow conveys the materials into the conveying inner pipe 51, then enters the discharging pipeline 6 through the conveying inner pipe 51, and under the action of the external pressurizing machine 54, the space between the conveying inner pipe 51 and the external pressurizing pipe 53 is continuously pressurized through the pressurizing ring pipe 52.
In this embodiment, the inner conveying pipe 51 is provided with a plurality of unidirectional air injection ports 511 distributed in a ring shape. When the pressurizing machine 54 continuously pressurizes the space between the inner conveying pipe 51 and the outer pressurizing pipe 53 through the pressurizing ring pipe 52, the unidirectional gas injection ports 511 on the inner conveying pipe 51 are changed from a closed state to an open state, so that the unidirectional gas injection ports 511 continuously carry out gas flow conveying on the inner wall of the inner conveying pipe 51, the gas flow intensity of the unidirectional gas injection ports 511 is far smaller than that of the gas flow output by the gas blowing mechanism 2 to the conveying channel 5, normal conveying of materials is not affected, and direct contact between the materials and the inner conveying pipe 51 is avoided.
In this embodiment, a fixed gear 512 is disposed on the inner conveying pipe 51 between the outer pressurizing pipe 53 and the discharging pipe 6, and the fixed gear 512 is meshed with a transmission gear 513 on a rotating motor 514. Under the drive of the rotating motor 514, the transmission gear 513 drives the fixed gear 512 to rotate, and then drives the conveying inner pipe 51 to rotate, and under the continuous conveying of the airflow of the unidirectional air injection port 511, the inner wall of the conveying inner pipe 51 forms a protective air layer to protect the conveyed materials, so that the materials are effectively prevented from adhering to the inner wall of the conveying inner pipe 51 and accumulating.
In the specific implementation, firstly, when the crushed dry materials are conveyed, under the action of the rotating handle 32, the rotating shaft 31 drives the adjusting disc 33 to rotate, so that the inclination angle of the adjusting disc 33 is close to the horizontal, at the moment, the rotating cambered surface 362 in the guide surface 36 is overlapped with the fixed cambered surface 361, and then when the materials are conveyed by the feed inlet 4, the materials uniformly fall into the feed pipeline 3 under the action of the dispersing cambered surface 41, under the action of the air blowing mechanism 2, the materials are blown into the conveying channel 5, the partially agglomerated materials fall onto the adjusting disc 33, under the action of the reciprocating mechanism 35, the dispersing blades 34 rotate back and forth to disperse the agglomeration, And drives the cleaning member 335 to move between the gaps of the spiral springs 333 to clean the materials clamped between the gaps, and simultaneously the air flow in the feeding pipeline 3 positioned at the lower part of the adjusting disc 33 is guided by the guide surface 36 to blow upwards from the bottom of the adjusting disc 33 to blow up the scattered materials on the adjusting disc 33, and the materials are blown into the conveying channel 5 under the blowing of the top air flow, in the process, if the crushing degree of the materials is high, the individual is small, the spiral springs 333 are released through the central shaft 331, the whole length of the spiral springs 333 is further prolonged, the total number of turns is increased, the gaps are reduced, and then the corresponding cleaning member 335 is manually installed, so that the cleaning member 335 can move in the gap between the spiral springs 333 to clean the material clamped between the gaps, so as to ensure the circulation of air flow, if the crushing degree of the material is low, the spiral springs 333 are retracted through the central shaft 331, the cleaning member 335 of the inner ring is removed before retraction, the whole length of the spiral springs 333 is shortened, the total number of turns is reduced, the gap is increased, the blocking of the air flow in the air blowing mechanism 2 is reduced, the blowing force of the material is enhanced, and the dispersed material is rapidly conveyed into the conveying channel 5; When the crushed wet materials are conveyed, under the action of the rotating handle 32, the rotating shaft 31 drives the adjusting disc 33 to rotate, so that the inclination angle of the adjusting disc 33 is increased, the adjusting disc 33 is in an inclined state, the higher end of the adjusting disc 33 corresponds to the dispersing cambered surface 41 at the bottom of the feed inlet 4, the rotating cambered surface 362 in the guide surface 36 is connected with the fixed cambered surface 361, the materials uniformly fall into the feed pipeline 3 and onto the adjusting disc 33 under the action of the dispersing cambered surface 41 when the materials are conveyed by the feed inlet 4, the back of the air flow self-adjusting disc 33 of the air blowing mechanism 2 flows to the conveying channel 5, and the scattered materials are directly blown into the conveying channel 5, The upper part of the material self-adjusting disc 33 which is partially agglomerated rolls downwards, meanwhile, in the rolling process, the scattering blades 34 rotate back and forth to scatter the agglomeration and drive the cleaning piece 335 to move between the gaps of the spiral springs 333 to clean the material clamped between the gaps, then under the continuous blowing of the air flow in the feeding pipeline 3 to the adjusting disc 33, the agglomerated material is scattered and blown into the conveying channel 5 in the falling process, and under the action of the flow guiding surface 36, part of the air flow is converged at the lower end of the adjusting disc 33 and blown out, under the cooperation of the scattering blades 34, the material at the lower end of the adjusting disc 33 is scattered and discharged, and similarly, according to the crushing degree of the material, Namely, the size of the material is adjusted by the spiral spring 333 in the adjusting disc 33, when the material enters the inner conveying pipe 51, the inner conveying pipe 51 is driven to rotate by the rotating motor 514, meanwhile, the pressurizing machine 54 continuously pressurizes the space between the inner conveying pipe 51 and the outer pressurizing pipe 53 through the pressurizing ring pipe 52, a protective air layer is formed on the inner wall of the inner conveying pipe 51 under the action of the unidirectional air injection port 511, the material in conveying is protected, the material is effectively prevented from being adhered to the inner wall of the inner conveying pipe 51, accumulation is caused, the materials with different crushing degrees are conveyed into different extrusion forming devices, and the materials are extruded into biomass particles with different specifications.
