Technical Field

[0001] The invention relates to the technical field of pelletizers, in particular to a biomass pelletizer and a use method thereof. Background Art

[0002] Biomass pellet mill is a kind of equipment used to process biomass raw materials (such as wood chips, straw, rice husks, etc.) into biomass pellet fuel. The working principle of the pellet mill is to feed the biomass raw materials into the pellet mill, and after being squeezed and treated at high temperature between the roller and the die, the raw materials are formed into pellets in the die hole, and then cut into pellet fuel of the required length by the cutting device.

[0015] A biomass pellet granulator and a method for using the same, the method for using the biomass pellet granulator comprising the following steps:

[0016] Step 1: Start the motor, and the motor drives the screw rod to rotate. Because the square rod is stuck on the inner wall of the bearing shell, the screw rod can drive the threaded sleeve to descend during rotation, and the threaded sleeve drives the rotating plate to descend, and the rotating plate drives the moving block to descend. Due to the setting of the slide slot, the moving block drives the slider to move along the track of the slide slot during the falling process, and the moving block drives the rubber arc block to move during the horizontal movement process. The rubber arc block will come into contact with the cylinder during the movement process and squeeze the cylinder. In the process of downward movement, the threaded sleeve drives the fixed shell to move downward, and the fixed shell drives the heat conduction plate to move downward;

[0017] Step 2: When the threaded sleeve moves downward, the threaded sleeve drives the square rod to move downward. When the square rod moves downward to a certain position, the bearing shell is no longer blocked, so that the screw drives the threaded sleeve to rotate, and the threaded sleeve drives the square rod and the round rod to rotate. The round rod drives the stirring sleeve to rotate. At this time, the staff pours the material into the bearing shell through the hopper, and the stirring sleeve crushes the material. The crushed material enters the cylinder through the square groove. In the process of the round rod falling, the stirring sleeve is driven to fall, and the stirring sleeve drives the rotating sleeve to fall. The rotating sleeve drives the first air pressure plate to fall. In the process of the first air pressure plate falling, the air pressure inside the circular shell enters the inside of the annular bag through the air pipe, so that the annular bag expands. In the process of the annular bag expanding, the bearing shell is expanded outward, and in the process of the rotating sleeve falling, the rubber curved rod is driven to rotate and move downward. In the process of the rubber curved rod rotating and moving downward, the annular bag is squeezed.

[0018] Step 3: Because the square rod and the gear are clamped together, when the square rod rotates, the square rod can drive the tooth column to rotate in the opposite direction, the tooth column drives the inner gear sleeve to rotate in the opposite direction, the inner gear sleeve drives the connecting plate to rotate in the opposite direction, and the connecting plate drives the friction plate to rotate in the opposite direction, so that the rotation of the friction plate and the fixed shell is opposite, and the inner gear sleeve drives the vertical rod to rotate in the opposite direction, and the vertical rod drives the granulating roller to rotate in the opposite direction. When the slider moves to one end of the slide slot, the slider drives the cross sleeve to rotate as a whole, and the cross sleeve drives the cylinder to rotate, so that the granulating roller can rotate and rub in the opposite direction to the cylinder, so that the material moves outward through the granulating hole at the cylinder;

[0019] Step 4: When the moving block moves, the moving block drives the cross bar to move, and the cross bar drives the second air pressure plate to move. When the second air pressure plate moves inside the sealing shell, negative pressure will be generated. The negative pressure enters the negative pressure shell through the curved pipe, and the negative pressure enters the connecting pipe through the negative pressure shell. The negative pressure enters the arc sleeve through the connecting pipe. The negative pressure makes the two sliding plates inside the arc sleeve approach each other, and the sliding plate drives the arc rod to move. When the material moves to the outside through the granulation hole, the special-shaped blade driven by the arc rod cuts the material particles. In the process of the second air pressure plate moving, the second air pressure plate drives the rubber rope to move, the rubber rope is stretched, the rubber rope drives the ferrule to move downward, and the ferrule drives the special-shaped blade to move downward.

[0020] The present invention has the following beneficial effects:

[0021] 2. The present invention starts the motor, and the motor drives the screw rod to rotate. Because the square rod is stuck at the inner wall of the bearing shell, the screw rod can drive the threaded sleeve to descend during rotation, and the threaded sleeve drives the rotating plate to descend, and the rotating plate drives the moving block to descend. Due to the setting of the slide groove, the moving block drives the slider to move along the trajectory of the slide groove during the falling process, and drives the rubber arc block to move during the transverse movement of the moving block. The rubber arc block will come into contact with the cylinder during the movement process, squeeze the cylinder, enhance the stability of the cylinder, and improve the protection effect of the cylinder. In the process of downward movement of the threaded sleeve, it drives the fixed shell to move downward, and the fixed shell drives the heat conduction plate to move downward. In the process of downward movement of the heat conduction plate, the space capacity for loading materials inside the cylinder is expanded, thereby improving the granulation efficiency of the device.

[0022] (2) In the present invention, when the threaded sleeve moves downward, the threaded sleeve drives the square rod to move downward. When the square rod moves downward to a certain position, it no longer blocks the bearing shell, so that the screw rod drives the threaded sleeve to rotate, and the threaded sleeve drives the square rod and the round rod to rotate. The round rod drives the stirring sleeve to rotate. At this time, the staff pours the material into the bearing shell through the hopper, and the stirring sleeve crushes the material. The crushed material enters the inside of the cylinder through the square groove. In the process of the round rod falling, it drives the stirring sleeve to fall, and the stirring sleeve drives the rotating sleeve to fall. The rotating sleeve drives the first air pressure plate to fall. During the falling process of the first air pressure plate, the air pressure inside the circular shell enters into the annular bag through the air pipe, causing the annular bag to expand. During the expansion of the annular bag, the support shell expands outward, so that the granulating roller and the support shell fit more closely, thereby enhancing the extrusion and granulation effect of the granulating roller. In the falling process of the rotating sleeve, the rubber bending rod is driven to rotate and move downward. During the rotation and downward movement of the rubber bending rod, the annular bag is squeezed, so that the expansion effect of the annular bag is enhanced, thereby further improving the fitting effect between the granulating roller and the support shell.

[0023] (3) In the present invention, since the square rod and the gear are clamped together, when the square rod rotates, the square rod can drive the tooth column to rotate in the opposite direction, the tooth column drives the inner gear sleeve to rotate in the opposite direction, the inner gear sleeve drives the connecting plate to rotate in the opposite direction, and the connecting plate drives the friction plate to rotate in the opposite direction, so that the rotation of the friction plate and the fixed shell is opposite, thereby enhancing the friction effect between the friction plate and the fixed shell, so that the internal airflow of the fixed shell is heated, and the hot air flow is conducted through the heat conduction plate, thereby heating the crushed material, and accelerating the working efficiency of the material granulation. In addition, the inner gear sleeve drives the vertical rod to rotate in the opposite direction, and the vertical rod drives the granulating roller to rotate in the opposite direction. When the slider moves to one end of the slide groove, the slider drives the cross sleeve to rotate as a whole, and the cross sleeve drives the cylinder to rotate, so that the granulating roller can rotate and rub in the opposite direction to the cylinder, so that the material moves outward through the granulating hole at the cylinder, thereby further accelerating the extrusion granulation efficiency of the granulating roller.

[0024] (4) In the present invention, when the moving block moves, the moving block drives the cross bar to move, and the cross bar drives the second air pressure plate to move. When the second air pressure plate moves inside the sealed shell, negative pressure is generated. The negative pressure enters the negative pressure shell through the bent pipe, and then enters the connecting pipe through the negative pressure shell. The negative pressure enters the arc sleeve through the connecting pipe. The negative pressure makes the two sliding plates inside the arc sleeve approach each other, and the sliding plate drives the arc rod to move, so that the multiple arc sleeves move toward the round rod, and the multiple arc sleeves squeeze the cylinder. The fitting effect between the cylinder and the granulating roller is enhanced, and the extrusion granulating effect of the granulating roller is enhanced on the side. When the material moves to the outside through the granulating hole, the special-shaped blade driven by the arc rod cuts the material particles, and during the movement of the second air pressure plate, the second air pressure plate drives the rubber rope to move, the rubber rope is stretched, the rubber rope drives the ferrule to move downward, and the ferrule drives the special-shaped blade to move downward, thereby enhancing the stability of the special-shaped blade, preventing the special-shaped blade from shaking when the arc rod moves, enhancing the cutting effect of the special-shaped blade, and enhancing the granulation quality of the material.

[0054] Step 1: Start the motor 51, the motor 51 drives the screw rod 52 to rotate, because the square rod 561 is stuck on the inner wall of the bearing shell 54, so that the screw rod 52 can drive the threaded sleeve 53 to descend during its rotation, the threaded sleeve 53 drives the rotating plate 552 to descend, the rotating plate 552 drives the moving block 553 to descend, and due to the setting of the slide groove 556, the moving block 553 drives the slider 555 to move along the track of the slide groove 556 during its falling process, and the moving block 553 drives the rubber arc block 554 to move during its transverse movement, and the rubber arc block 554 will come into contact with the cylinder 579 during its movement, squeezing the cylinder 579, and the threaded sleeve 53 drives the fixed shell 557 to move downward during its downward movement, and the fixed shell 557 drives the heat conduction plate 578 to move downward;

[0055] Step 2: When the threaded sleeve 53 moves downward, the threaded sleeve 53 drives the square rod 561 to move downward. The square rod 561 moves downward to a certain position and no longer blocks the bearing shell 54, so that the screw rod 52 drives the threaded sleeve 53 to rotate. The threaded sleeve 53 drives the square rod 561 and the round rod 562 to rotate. The round rod 562 drives the stirring sleeve 563 to rotate. At this time, the staff pours the material into the inside of the bearing shell 54 through the hopper 2. The stirring sleeve 563 crushes the material. The crushed material enters the inside of the cylinder 579 through the square groove 5610, and the round rod 562 During the falling process, the stirring sleeve 563 is driven to fall, the stirring sleeve 563 drives the rotating sleeve 564 to fall, the rotating sleeve 564 drives the first air pressure plate 569 to fall, and during the falling process of the first air pressure plate 569, the air pressure inside the annular shell 566 enters into the annular capsule 567 through the air pipe 568, so that the annular capsule 567 expands, and during the expansion of the annular capsule 567, the bearing shell 54 expands outward, and during the falling process of the rotating sleeve 564, the rubber curved rod 565 is driven to rotate and move downward, and during the rotation and downward movement of the rubber curved rod 565, the annular capsule 567 is squeezed;

[0056] Step 3: Because the square rod 561 and the gear 571 are clamped together, when the square rod 561 rotates, the square rod 561 can drive the tooth column 572 to rotate in the opposite direction, the tooth column 572 drives the inner gear sleeve 573 to rotate in the opposite direction, the inner gear sleeve 573 drives the connecting plate 574 to rotate in the opposite direction, and the connecting plate 574 drives the friction plate 575 to rotate in the opposite direction, so that the rotation of the friction plate 575 and the fixed shell 557 is opposite, and the inner gear sleeve 573 drives the vertical rod 576 to rotate in the opposite direction, and the vertical rod 576 drives the granulating roller 577 to rotate in the opposite direction.

[0057] Step 4: When the moving block 553 moves, the moving block 553 drives the cross bar 581 to move, and the cross bar 581 drives the second air pressure plate 582 to move. When the second air pressure plate 582 moves inside the sealing shell 583, negative pressure is generated. The negative pressure enters the inside of the negative pressure shell 586 through the curved pipe 584, and the negative pressure enters the inside of the connecting pipe 587 through the negative pressure shell 586. The negative pressure enters the inside of the arc sleeve 588 through the connecting pipe 587, and the negative pressure causes the two sliding plates inside the arc sleeve 588 to move. 5811 approach each other, the sliding plate 5811 drives the arc rod 5816 to move, when the material moves to the outside through the granulation hole 5710, the special-shaped blade 5812 driven by the arc rod 5816 cuts the material particles, and during the movement of the second air pressure plate 582, the second air pressure plate 582 drives the rubber rope 5815 to move, the rubber rope 5815 is stretched, the rubber rope 5815 drives the ferrule 5814 to move downward, and the ferrule 5814 drives the special-shaped blade 5812 to move downward.

[0058] During use, because the square rod 561 and the gear 571 are clamped together, when the square rod 561 rotates, the square rod 561 can drive the tooth column 572 to rotate in the opposite direction, the tooth column 572 drives the inner gear sleeve 573 to rotate in the opposite direction, the inner gear sleeve 573 drives the connecting plate 574 to rotate in the opposite direction, and the connecting plate 574 drives the friction plate 575 to rotate in the opposite direction, so that the rotation of the friction plate 575 and the fixed shell 557 is opposite, which enhances the friction effect between the friction plate 575 and the fixed shell 557, so that the internal airflow of the fixed shell 557 is heated, and the hot airflow is conducted through the heat conduction plate 578. , thereby heating up the crushed material and accelerating the efficiency of material granulation, and the inner gear sleeve 573 drives the vertical rod 576 to rotate in the opposite direction, and the vertical rod 576 drives the granulating roller 577 to rotate in the opposite direction. When the slider 555 moves to one end of the slide groove 556, the slider 555 drives the cross sleeve 551 to rotate as a whole, and the cross sleeve 551 drives the cylinder 579 to rotate, so that the granulating roller 577 can rotate and rub in the opposite direction to the cylinder 579, so that the material moves outward through the granulating hole 5710 at the cylinder 579, thereby further accelerating the extrusion granulation efficiency of the granulating roller 577.

[0059] When the moving block 553 moves, the moving block 553 drives the cross bar 581 to move, and the cross bar 581 drives the second air pressure plate 582 to move. When the second air pressure plate 582 moves inside the sealing shell 583, negative pressure will be generated. The negative pressure enters the inside of the negative pressure shell 586 through the bent pipe 584, and the negative pressure enters the inside of the connecting pipe 587 through the negative pressure shell 586. The negative pressure enters the inside of the arc sleeve 588 through the connecting pipe 587. The negative pressure makes the two sliding plates 5811 inside the arc sleeve 588 approach each other, and the sliding plate 5811 drives the arc rod 5816 to move, so that the multiple arc sleeves 588 move toward the round rod 562, and the multiple arc sleeves 588 squeeze the cylinder 579, thereby enhancing the cylinder The fitting effect between 579 and the granulating roller 577 enhances the extrusion granulation effect of the granulating roller 577 from the side. When the material moves to the outside through the granulating hole 5710, the special-shaped blade 5812 driven by the arc rod 5816 cuts the material particles. In the movement of the second air pressure plate 582, the second air pressure plate 582 drives the rubber rope 5815 to move. The rubber rope 5815 is stretched, and the rubber rope 5815 drives the ferrule 5814 to move downward. The ferrule 5814 drives the special-shaped blade 5812 to move downward, thereby enhancing the stability of the special-shaped blade 5812 and preventing the special-shaped blade 5812 from shaking when the arc rod 5816 moves, thereby enhancing the cutting effect of the special-shaped blade 5812 and enhancing the granulation quality of the material.
