Description

Technical Field

[0001] This invention relates to the field of straw carbonization fertilizer production technology, specifically to an integrated equipment for straw carbonization, granulation, and fertilizer production. Background Technology

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. Agricultural production generates a large amount of straw, which is traditionally disposed of by burning. This method pollutes the air and yields little benefit. Straw carbonization is an effective alternative. Straw carbonization involves drying or sun-drying the straw, crushing it, and then processing it in a charcoal-making device through crushing, dry distillation, and cooling to produce charcoal. To shorten the preparation process and reduce complexity, existing straw carbonization systems utilize integrated carbonization and granulation machines, combining carbonization and granulation into one process to improve fertilizer production.

[0003] The invention with application number CN202123019193.X discloses an integrated machine for straw carbonization, granulation, and fertilizer production. An air pump draws external air into a heating cylinder, where heating rods generate heat. This heat is transferred to a heat-conducting ring, and then the air, carrying heat, enters the crushing assembly through contact with the heating rods and the heat-conducting ring. The air, carrying water vapor, is discharged from the feeding cylinder, thus preheating and drying the straw during processing, improving its dryness.

[0004] The above-mentioned device uses hot air to dry the straw during the crushing process. The straw passes through the drying components for a very short time, which is insufficient for drying. The straw is crushed quickly, and the crushing is completed before the straw is completely dry. This results in incomplete drying of the straw, reduced drying efficiency, and low quality of carbonized fertilizer.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems by designing an integrated equipment for straw carbonization, granulation, and fertilizer production.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A straw carbonization, granulation, and fertilizer production integrated equipment includes a carbonization machine body and a crushing cylinder. The crushing cylinder is positioned above the carbonization machine body, and support legs are installed at the four corners of the carbonization machine body. A drying chamber is connected to the top of the crushing cylinder, and a feed inlet is provided at the top of the drying chamber. Two heating rollers are rotatably connected inside the drying chamber, and the two heating rollers are located below the feed inlet. Two hollow rotating cylinders are rotatably connected inside the drying chamber, and the two hollow rotating cylinders are located directly below the two heating rollers. Air outlets are provided around the hollow rotating cylinders, and both ends of the hollow rotating cylinders extend through the crushing cylinder. A rotary joint is connected to one end of the hollow rotating cylinder. A fixed support plate is installed on one side of the drying chamber, and a hot air fan is installed on the fixed support plate. The air outlet of the hot air fan is connected to a U-shaped air conveying pipe, and both ends of the U-shaped air conveying pipe are connected to air supply pipes. One end of the air supply pipe is connected to the rotary joint.

[0008] Furthermore, a motor bracket is installed on one side of the drying chamber, and two drive motors are installed on the motor bracket. The output end of the drive motor is fixedly connected to one end of the heating roller. The other end of the heating roller extends through the drying chamber. A drive gear is installed at the end of the heating roller extending through the drying chamber, and a driven gear is installed at the other end of the hollow rotating drum. Two auxiliary gears are installed on the drying chamber, and the auxiliary gears mesh with the drive gear and the driven gear, respectively.

[0009] Furthermore, a feed hopper is installed on the top of the drying chamber, and the feed hopper is connected to the feed inlet. A power push rod is installed on the drying chamber, and the power push rod is located on one side of the feed hopper. A rotating bracket is installed on the telescopic end of the power push rod, and a pressing plate is installed on one end of the rotating bracket. The pressing plate is located directly above the feed hopper.

[0010] Furthermore, two electric heating plates are installed inside the drying oven. The two electric heating plates are inclined, and the distance between the two electric heating plates is greater than the distance between the two hollow rotating cylinders.

[0011] Furthermore, there are two of each of the drive motor, heating roller, and hollow rotating drum. The two drive motors drive the two heating rollers to rotate relative to each other, and the gap between the two heating rollers is the same as the gap between the two hollow rotating drums.

[0012] Furthermore, the size of the feed hopper is the same as the size of the feed inlet, and the size of the pressing plate is the same as the size of the feed inlet.

[0013] Compared with existing technologies, this technical solution has the following beneficial effects: Two heating rollers rotate in opposite directions to compress the straw, while the heating rollers generate heat to dry the straw. The compression ensures full contact between the straw and the heating rollers, allowing for thorough drying. This also slows down the descent of the straw. Two hollow rotating drums rotate in opposite directions, blowing hot air through the straw. The straw passes between the two hollow drums, and the hot air hits the surface of the straw, heating and drying it. The hot air fills the entire drying chamber, and the slow descent of the straw ensures thorough heating and drying, improving the drying, carbonization, and fertilizer production effects. Hot air continuously blows out from the air outlet to prevent straw from entering the hollow rotating drums through the outlet. The pressing plate can be rotated and moved by rotating the rotating bracket. When putting straw in, the pressing plate can be rotated away from the feeding hopper to make it easier to put the straw into the feeding hopper. After the straw is put into the feeding hopper, the pressing plate is positioned directly above the feeding hopper by rotating the rotating bracket. The pressing plate presses the straw in the feeding hopper downwards, making it easier for the straw to enter the drying box. The straw can be heated by an electric heating plate. Some straw that does not pass between the two heating rollers and the hollow drum falls onto the electric heating plate, which improves the drying effect. The electric heating plate is set at an angle, which can guide the straw. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] This invention provides, for example Figure 1-5 The illustrated straw carbonization, granulation, and fertilizer production integrated equipment includes a carbonization machine body 1 and a crushing cylinder 2. The crushing cylinder 2 is positioned above the carbonization machine body 1. Support legs 3 are installed at the four corners of the carbonization machine body 1. A drying chamber 4 is connected to the top of the crushing cylinder 2. A feed inlet 5 is provided at the top of the drying chamber 4. Two heating rollers 6 are rotatably connected inside the drying chamber 4, located below the feed inlet 5. Two hollow rotating cylinders 7 are rotatably connected inside the drying chamber 4, located directly below the two heating rollers 6. Air outlets 23 are provided around the hollow rotating cylinders 7. Both ends of the hollow rotating cylinders 7 extend through the crushing cylinder 2. A rotary joint 8 is connected to one end of the hollow rotating cylinders 7. A fixed support plate 9 is installed on one side of the drying chamber 4. A hot air blower 10 is installed on the fixed support plate 9. The air outlet of the hot air blower 10 is connected to a U-shaped air conveying pipe 11. Both ends of the U-shaped air conveying pipe 11 are connected to air supply pipes 12. One end of the air supply pipe 12 is connected to the rotary joint 8.

[0018] During operation, straw enters the drying chamber 4 through the feed inlet 5. Two heating rollers 6 rotate relative to each other, simultaneously starting their operation. The straw passes between the two heating rollers 6, which compress it. The heating rollers 6 generate heat to dry the straw. This compression ensures full contact between the straw and the heating rollers 6, effectively drying the straw and slowing its descent. Meanwhile, two hollow rotating drums 7 rotate relative to each other, and the hot air blower 10 starts operating. The hot air generated by the hot air blower 10 passes through a U-shaped air duct 11, an air supply pipe 12, and a rotating connector. The straw is fed into the hollow rotating drum 7. The hot air inside the hollow rotating drum 7 is blown out through the air outlet 23. The straw passes between the two hollow rotating drums 7. The hot air blows on the surface of the straw, heating and drying it. At the same time, the hot air can fill the entire drying box 4. The straw falls slowly, which can fully heat and dry the straw, improving the straw drying effect, carbonization effect, and fertilizer production effect. The hot air continues to blow out from the air outlet 23 to prevent the straw from entering the hollow rotating drum 7 through the air outlet 23. After drying, the straw enters the crushing drum 2 for crushing and then enters the carbonization machine body 1.

[0019] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 5 A motor bracket 13 is installed on one side of the drying chamber 4. Two drive motors 14 are installed on the motor bracket 13. The output end of the drive motor 14 is fixedly connected to one end of the heating roller 6. The other end of the heating roller 6 extends through the drying chamber 4. A drive gear 15 is installed at one end of the heating roller 6 extending out of the drying chamber 4. A driven gear 16 is installed at the other end of the hollow rotating drum 7. Two auxiliary gears 17 are installed on the drying chamber 4. The auxiliary gears 17 mesh with the drive gear 15 and the driven gear 16 respectively.

[0020] When the drive motor 14 starts working, the output directions of the two drive motors 14 are opposite. The two drive motors 14 drive the two heating rollers 6 to rotate relative to each other. When the heating rollers 6 rotate, they drive the drive gear 15 to rotate. The drive gear 15 meshes with the auxiliary gear 17. The drive gear 15 drives the auxiliary gear 17 to rotate. The auxiliary gear 17 meshes with the driven gear 16. The auxiliary gear 17 drives the driven gear 16 to rotate. The driven gear 16 drives the hollow drum 7 to rotate.

The drying chamber 4 is equipped with a power push rod 19, which is located on one side of the feed hopper 18. A rotating bracket 20 is installed on the telescopic end of the power push rod 19. A pressing plate 21 is installed on one end of the rotating bracket 20, which is located directly above the feed hopper 18.

[0022] The pressing plate 21 can be rotated and moved by rotating the rotating bracket 20. When putting straw in, the pressing plate 21 can be rotated away from the feeding hopper 18 to facilitate the putting of straw into the feeding hopper 18. After the straw is put into the feeding hopper 18, the pressing plate 21 is positioned directly above the feeding hopper 18 by rotating the rotating bracket 20. The power push rod 19 starts to work. The telescopic end of the power push rod 19 retracts and drives the pressing plate 21 to descend through the rotating bracket 20. The pressing plate 21 squeezes the straw in the feeding hopper 18 downwards, making it easier for the straw to enter the drying box 4.

[0023] Refer to the instruction manual appendix Figure 2 The drying oven 4 is equipped with two electric heating plates 22, which are inclined and the distance between the two electric heating plates 22 is greater than the distance between the two hollow rotating cylinders.

[0024] After passing through the hollow rotating drum 7, the straw falls onto the electric heating plate 22. The electric heating plate 22 starts to work and can heat the straw. Some straw that did not pass between the two heating rollers 6 and the hollow rotating drum 7 falls onto the electric heating plate 22. The drying effect is improved by the electric heating plate 22 being inclined, which can guide the straw.
