Description

Technical Field

[0001] The present invention relates to the technical field of new energy fuel pulverization, and in particular to a new energy fuel pulverization and pressurization device. Background Art

[0002] New energy fuels refer to those energy sources that can replace traditional fossil fuels. They are renewable, clean and environmentally friendly. There are many types of new energy fuels, including biomass fuels, solar fuels and hydrogen fuels. Biomass fuels are combustible substances converted from plant or animal waste, solar fuels are combustible substances that convert solar energy into chemical energy through photochemical reactions, and hydrogen fuel is a clean energy source composed of hydrogen molecules.

[0003] When producing new energy fuels, it is necessary to crush the raw materials, and the raw materials are often crushed with the help of a crushing device so that the raw materials can be processed in the next step. For example, a biomass fuel crusher with a patent publication number of CN117654688B can perform secondary crushing of biomass through crushing mechanisms such as a driving motor, a rotating rod and a crushing knife, and can grind biomass into powder through stirring mechanisms such as a servo motor, a stirring paddle and a steel ball, so that biomass can be processed into micron fuel, thereby improving the combustion efficiency of biomass fuel and avoiding incomplete combustion of large-particle biomass fuel;

[0004] However, the above-mentioned biomass fuel crusher crushes the biomass raw materials by a crushing knife and then grinds the biomass by a steel ball. When the steel ball grinds the raw materials after the secondary crushing, the raw materials fall from top to bottom through the set microporous filter plate. However, when the raw materials that are not fully ground by the steel ball sink to the bottom, that is, when they are on the upper surface of the microporous filter plate, the contact between the steel ball and the raw materials on the upper surface of the microporous filter plate is not as good as the collision effect between the raw materials above the microporous filter plate and the steel ball. This may cause the raw materials that sink to the bottom to be insufficiently ground and easily clog the microporous filter plate, which not only affects the falling of the raw materials, but also affects the crushing effect of the raw materials.

[0016] Compared with the existing technology, the advantages of this new energy fuel crushing and pressurizing device are:

[0017] 1. The raw materials are preliminarily crushed by two crushing rollers. The preliminarily crushed raw materials fall into the grinding barrel under the action of gravity, and the steel balls in the grinding barrel cooperate with the stirring rod and the stirring blades to crush the raw materials for the second time. The crushed raw materials fall into the guide bin one through the filter plate two, and fall into the guide bin two along the guide bin one, and finally fall out from the filter plate one. The staff can collect the filtered raw materials to complete the secondary crushing and secondary filtration of the raw materials, improve the filtering and crushing effect of the raw materials, and cooperate with the subsequent turning of the guide bin two to put the raw materials remaining on the filter plate one into the grinding barrel again for grinding, which can further improve the crushing effect of the raw materials;

[0018] 2. When the raw material is subjected to secondary ball milling, the connecting shaft 1 rotates with the stirring rod, which can make the disc rotate and the transmission gear 2 rotate. The teeth on the transmission gear 2 continuously move the connecting piece 1 and the connecting piece 2, driving the connecting shaft to rotate back and forth continuously, thereby driving the connecting rod and the insertion rod to continuously rotate back and forth in an arc-shaped trajectory as a whole. The sliding rod follows the insertion rod to move back and forth along the inside of the arc-shaped limit frame 1, which can limit the position of the insertion rod and prevent the insertion rod from shrinking into the connecting rod, thereby driving the cleaning roller to continuously knock on the bottom surface of the guide bin 2, so as to generate vibration and improve the filtering effect of the raw material. When the cleaning guide bin 2 flips to guide the material, the cleaning roller can also knock and vibrate the bottom surface of the guide bin 2 to promote the raw material to fall into the grinding barrel;

[0019] 3. After the raw materials are filtered for the second time, the motor 2 drives the stirring rod to reverse, and cooperates with the ratchet, the limit block, the transmission shaft and the transmission belt 3 to drive the long axis to rotate, so that the turntable rotates 180°, and cooperates with the movable rod 2 and the movable rod 1 to drive the movable block to slide, so that the transmission gear 2 is away from the connecting piece 1 and the connecting piece 2, so that the cleaning roller stops knocking the guide bin 2, and drives the disc away from the transmission gear 1, so that the rotating shaft 3 stops rotating, and in the process of the movement of the movable block 1, the L-shaped connecting rod moves with the movable block 1, and cooperates with the slope to make the transmission rack move down along the vertical rod, thereby driving the toggle gear to rotate counterclockwise, so that the connecting shaft rotates, driving the connecting rod and the plug rod to rotate with the connecting shaft as the center axis, so that the cleaning roller moves along the bottom surface of the filter plate 1, and the filter plate 1 can be cleaned and dredged to avoid the blockage of the filter plate 1 caused by larger raw materials, affecting the falling of the raw materials and the filtering effect.

[0020] 4. When the movable block slides, the connecting block moves with it, driving the roller 2 to move. The long plate rotates counterclockwise with the shaft connected to the bearing plate as the central axis, so that the roller 1 and the cover plate move horizontally to block the raw material above the filter plate 1. At the same time, when the cleaning roller moves to clean and dredge the filter plate 1, it can drive the arc-shaped limit frame 2 to move horizontally as a whole, thereby driving the horizontal rack to move, and cooperate with the transmission gear 3 and the oblique rack to move upward, so that the oblique guide plate moves up, and cooperates with the cover plate to seal the raw material in the guide bin 1 and at the upper end surface of the filter plate 1 to prevent leakage in the subsequent process of pouring the raw material back into the grinding barrel.

[0021] 5. When the motor 3 drives the rotating shaft 1 to rotate and the guide bin 2 is turned over, the arc-shaped rack rotates with the rotating shaft 1 and moves in a circular trajectory, which can drive the auxiliary gear to rotate, and cooperate with the reciprocating screw to rotate and move with the collar, so that the baffle slides into the guide bin 1 to block the guide bin 1, so that after the guide bin 2 is turned over, the raw materials falling from the filter plate 2 can be continuously received to prevent them from slipping out of the guide bin 1;

[0022] In summary, the present invention realizes secondary filtration and secondary crushing of raw materials, and the raw materials that are not fully crushed after the secondary filtration can be put into grinding again, which effectively improves the crushing effect, and the leakage of raw materials can be well avoided during the adding process. The auxiliary mechanism is used to knock and vibrate the material guide bin 2 to promote the filtering effect. When the raw materials are added again, the material guide bin 2 can also be vibrated to promote material feeding, and at the same time, the filter plate 1 can be cleaned and unblocked to avoid the blockage of the filter plate 1 caused by larger raw materials, which affects the falling of the raw materials and the filtering effect.

[0046] When in use, the new energy fuel raw material to be crushed is placed in the crushing bin 3, and falls between the two crushing rollers 4 along the two baffles 5, and at the same time, the motor 1 is started to drive one of the rotating gears 7 to rotate, so that the other rotating gear 7 rotates in the opposite direction, thereby driving the two crushing rollers 4 to rotate, and the rotation directions are opposite, so that the raw material can be initially crushed, and the raw material after preliminary crushing falls into the grinding barrel 1 under the action of gravity, and before that, steel balls are put into the grinding barrel 1 through the feeding port 10, and at this time, the stirring rod 8 and the stirring blade 9 are driven by the forward rotation of the motor 2 to rotate, and the steel balls and the raw materials are stirred, so that the steel balls continuously collide with the raw materials, and the raw materials can be secondary crushed, and the crushed raw materials fall into the guide bin 1 6 through the filter plate 2 71, and fall into the guide bin 2 32 along the guide bin 1 6, and finally fall out from the filter plate 1 33, and the staff can collect the filtered raw materials to complete the secondary crushing and secondary filtering of the raw materials, wherein the larger raw materials that are not fully crushed filtered out by the filter plate 1 33 are still in the guide bin 2 32;

[0047] When the raw material is subjected to secondary ball milling, the connecting shaft 13 installed in the protective shell 14 rotates with the stirring rod 8, driving the bevel gear 2 17 to rotate, thereby driving the connecting shaft 2 15 to rotate, and cooperates with the transmission belt 1 20 to drive the connecting shaft 3 19 to rotate, and then cooperates with the transmission belt 2 22 to drive the rotating shaft 2 39 to rotate, and then drives the transmission gear 1 40 to rotate, and cooperates with the tooth groove to drive the disc 44 to rotate, and the transmission gear 2 43 rotates with the rotating shaft 3 42, so that each tooth on the transmission gear 2 43 continuously moves the connecting piece 1 53 and the connecting piece 2 54, driving the connecting shaft 48 to rotate back and forth continuously, thereby driving the connecting rod 55 and the insertion rod 76 to continuously rotate back and forth in an arc-shaped trajectory as a whole. In this process, the sliding rod 57 follows the insertion rod 76 to reciprocate along the inside of the arc-shaped limit frame 1 56, which can limit the position of the insertion rod 76 and prevent the insertion rod 76 from shrinking into the connecting rod 55, so that the cleaning roller 64 can be driven to continuously knock on the bottom surface of the guide bin 2 32, so that vibration is generated, thereby improving the filtering effect of the raw material;

[0048] After the raw materials are filtered for the second time, the stirring rod 8 is driven by the motor 2 to reverse, and the rotating shaft 2 39 can be reversed in the same way. When the motor 2 drives the rotating shaft 2 39 to rotate forward, the limit block 26 can move in a circular trajectory with the rotating shaft 2 39, and will not drive the ratchet 24 to rotate. When the motor 2 drives the rotating shaft 2 39 to reverse, the limit block 26 engages with the inner wall of the ratchet 24, which can drive the ratchet 24 to rotate, thereby driving the transmission shaft 27 to rotate, and cooperates with the motor 3 to drive the rotating shaft 1 38 to rotate, and cooperates with the transmission belt 3 28 to drive the long shaft 29 to rotate, thereby driving the turntable 60 to rotate 180 °, so that one end of the movable rod 2 59 moves in a semicircular trajectory, and the other end of the movable rod 2 59 rotates with the movable rod 1 58, and can drive one end of the movable rod 1 58 to move horizontally, drive the movable block 41 to slide, drive the transmission gear 2 43 away from the connecting piece 1 53 and the connecting piece 2 54, so that the cleaning roller 64 stops knocking the guide bin 2 32, and drives the disc 44 away from the transmission gear 1 40, releases the engagement, and stops the rotation of the shaft 3 42. In the process of moving the movable block 1 41, the L-shaped connecting rod 50 moves with the movable block 1 41, thereby driving the ramp block 49 to move horizontally. Figure 7 , so that the transmission rack 46 moves down along the vertical rod 45, thereby driving the toggle gear 47 to rotate counterclockwise, so that the connecting shaft 48 rotates, driving the connecting rod 55 and the insertion rod 76 to rotate with the connecting shaft 48 as the center axis, so that the cleaning roller 64 moves along the bottom surface of the filter plate 33, and the filter plate 33 can be cleaned and unblocked to prevent larger raw materials from clogging the filter plate 33 and affecting the falling of the raw materials.

[0049] Reference Figure 5-Figure 7 The shielding mechanism includes a connecting block 75, a long plate 70 and two slide grooves 74. The connecting block 75 is fixedly installed at the outer wall position of the movable block 41. The two slide grooves 74 are arranged on the upper surface position of the guide bin 32. The long plate 70 is rotatably connected to the outer wall position of the bearing plate 30 through an axle rod. The outer wall of the connecting block 75 is rotatably connected with a roller 2 72. A supporting spring 3 is fixedly installed between the outer wall of the long plate 70 and the outer wall of the guide bin 32. The two slide grooves 74 are slidably connected with T-shaped sliding blocks 73. The upper ends of the two T-shaped sliding blocks 73 are fixed. A cover plate 68 is fixedly installed, one end of the cover plate 68 is rotatably connected to a roller 1 69, and the roller 1 69 is in conflict with one end of the long board 70, and the roller 2 72 is in conflict with the other end of the long board 70. A return spring is installed between the inner wall of the slide groove 74 and the outer wall of the T-shaped sliding block 73. The friction between the roller 1 69, the cover plate 68 and the long board 70 makes it easier to push the cover plate 68 to move when the long board 70 rotates. At this time, the support spring 3 is compressed, and subsequently, under the action of the elastic force of the support spring 3, the long board 70 can be assisted to return to its initial position.

[0050] Reference Figure 5 , Fig.12 and Fig.14The material guiding mechanism comprises a fixed plate 61, which is fixedly mounted on the outer wall of the material guiding bin 2 32, and a transverse rack 62 is slidably connected to the inner wall of the fixed plate 61, and a transmission gear 3 65 is rotatably connected to the inner wall of the fixed plate 61 and located below the transverse rack 62 through an axle rod, and the transmission gear 3 65 is meshed with the transverse rack 62, and an oblique rack 66 is meshed with the transmission gear 3 65, and an oblique guide plate 67 is fixedly connected to the outer wall of the oblique rack 66 near the upper end, and the oblique guide plate 67 is slidably connected to the material guiding bin 2 32, and an arc-shaped limit frame 2 63 is fixedly connected to the upper end surface of the transverse rack 62, and the arc-shaped limit frame 2 63 is slidably connected to the cleaning roller 64, and when the cleaning roller 64 continuously strikes the bottom surface of the material guiding bin 2 32, one end of the cleaning roller 64 can move along the arc-shaped limit frame 2 63, so that the arc-shaped limit frame 2 63 does not affect the movement of the cleaning roller 64.

[0051] Specifically, when the movable block 41 slides, the connecting block 75 moves with it, driving the roller 2 72 to move. Fig.10, thereby driving the long plate 70 to rotate counterclockwise with the shaft connected to the carrying plate 30 as the central axis, so that the roller 1 69 and the cover plate 68 are translated, so that the cover plate 68 slides to the upper end of the guide bin 2 32 and is located above the filter plate 1 33 through the T-shaped sliding block 73 and the sliding groove 74, and blocks the raw materials above the filter plate 1 33. At the same time, when the cleaning roller 64 moves to clean and dredge the filter plate 1 33, it can drive the arc-shaped limit frame 2 63 to move horizontally as a whole, thereby driving the horizontal rack 62 to move, and then driving the transmission gear 3 65 to rotate, driving the oblique rack 66 The guide plate 11 in the feeding port 10 is inserted into the guide bin 32 and fits into the outer wall of the guide plate 11 and is in contact with the outer wall of the guide plate 11. The guide plate 11 in the feeding port 10 is inserted into the guide bin 32 and fits into the outer wall of the guide plate 11. At this time, the motor 2 is reversed again, so that the turntable 60 rotates 180 degrees again. After rotating 180 degrees, the motor 2 stops rotating immediately and starts to rotate forward, so that the movable block 41 moves to the initial position, the transmission gear 2 43 moves and the disk 44 moves to the initial position. The ramp block 49 moves to the initial position laterally at the same time, driving the transmission rack 46 to move upward, thereby driving the connecting rod 55, the insertion rod 76 and the sliding rod 57 to move to the initial position, and the tooth groove on the disk 44 re-engages with the transmission gear 1 40. Since the transmission gear 1 40 has been moved twice by 1 When reversed by 80°, its relative position remains unchanged, so it can re-engage with the disc 44 smoothly. At this time, the motor 2 rotates forward, and the cleaning roller 64 can knock and vibrate the bottom surface of the guide bin 2 32 to promote the raw materials to fall into the grinding barrel 1. Since the movable block 41 moves to the initial position, the cover plate 68 and the inclined guide plate 67 can be driven to move to the initial position to release the blockage of the raw materials. At this time, the raw materials can slide along the guide plate 11 and enter the grinding barrel 1 from the feeding port 10, and the raw materials staying on the filter plate 33 are ground again to improve the grinding effect of the raw materials.

[0052] Reference Figure 3-Figure 4The blocking mechanism includes an arc-shaped rack 37 and a reciprocating screw 35. The arc-shaped rack 37 is fixedly connected to the outer wall of the rotating shaft 38. The reciprocating screw 35 is rotatably connected to the bottom surface of the guide bin 6. A collar 36 is sleeved on the outside of the reciprocating screw 35, and a threaded groove matching the reciprocating screw 35 is opened on the inner wall of the collar 36. A baffle 34 is fixedly connected to the outer wall of the collar 36, and the baffle 34 is slidably connected to the guide bin 6. The end of the reciprocating screw 35 away from the guide bin 6 is fixedly connected to an auxiliary gear 77, and The auxiliary gear 77 is meshed with the arc-shaped rack 37, and a threaded groove matching the reciprocating screw 35 is provided on the inner wall of the collar 36. Since the collar 36 is connected to the baffle 34, one end of the baffle 34 is slidably connected to the guide bin 6, and one end of the baffle 34 is initially inserted into the outer wall of the guide bin 6, the collar 36 can be limited so that the collar 36 cannot rotate. When the reciprocating screw 35 rotates, the collar 36 can be driven to move with the cooperation of the thread, and then the baffle 34 can be driven to move.

[0053] Specifically, when the motor three drives the rotating shaft 1 38 to rotate and the material guide bin 2 32 is flipped, the arc-shaped rack 37 rotates with the rotating shaft 1 38 and moves in a circular trajectory, which can drive the auxiliary gear 77 to rotate, thereby driving the reciprocating screw 35 to rotate, and then driving the ring 36 to move, so that the baffle 34 slides into the material guide bin 1 6 to block the material guide bin 1 6, so that after the material guide bin 2 32 is flipped, the raw materials falling from the filter plate 2 71 can be continuously received to prevent them from sliding out of the material guide bin 1 6. After the material guide bin 2 32 is flipped back to its initial position, the baffle 34 slides out accordingly to release the blockage, so that the raw materials can continue to slide into the material guide bin 2 32 for secondary filtration.

[0054] It is further explained that the above-mentioned fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or one-piece forming and other conventional means well known to those skilled in the art.
