[0002] Biochar-based fertilizer is a new type of fertilizer made by combining biochar with organic or inorganic fertilizers. It has advantages such as improving soil structure and increasing fertilizer utilization.
[0003] The existing technology has the following problems:
[0004] In the production process of biochar-based fertilizer, the raw materials are first precisely conveyed to the disc granulator by an auger conveyor for granulation. The granules are then conveyed to the screening mechanism for screening to ensure that the product has a uniform particle size. However, since the particles have a high moisture content during the granulation process, they need to be dried in order to further improve the product's storage and performance. Traditional drying methods, such as static drying or hot air drying, are inefficient, resulting in a long drying time and uneven temperature control, which affects the overall quality of the particles and production efficiency. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1-5 As shown, a granulation and screening integrated device for biochar-based fertilizer includes a base plate 1, a disc granulator 2 installed on the top rear side of the base plate 1, a screening machine 3 installed on the top front side of the base plate 1, a drying mechanism 4 set on the top edge of the base plate 1, an auger conveyor 5 installed on the top left side of the base plate 1, a hopper 6 installed on the top of the auger conveyor 5, and a striking mechanism 7 set on the outer left side of the hopper 6.
[0027] The drying mechanism 4 includes a mounting frame 41, the bottom of which is fixedly connected to the top of the base plate 1. An annular guide rail 42 is fixedly connected to the inner bottom wall of the mounting frame 41. Two protrusions 43 are fixedly connected inside the annular guide rail 42. A hot air blower 44 is installed inside the annular guide rail 42. A rotating rod 45 is fixedly connected to the top of the hot air blower 44. A sleeve rod 46 is slidably connected to the outside of the rotating rod 45. A placement frame 47 is fixedly connected to the top of the sleeve rod 46. Two sliding rods 48 are fixedly connected to the bottom of the placement frame 47. A spring 49 is sleeved on the outside of the sliding rod 48. A roller 410 is installed at the bottom end of the spring 49. A ring 411 is slidably connected to the outside of the two sliding rods 48. An air inlet pipe 412 is fixedly connected to the right side of the outside of the mounting frame 41.
[0028] It should be noted that when the granulated particles need to be dried, the hot air blower 44 is started, and external air enters the mounting frame 41 through the air inlet pipe 412. The rotation of the hot air blower 44 drives the rotating rod 45 to rotate, which in turn drives the sleeve rod 46 to rotate. The sleeve rod 46 then drives the placement frame 47 to rotate, which in turn drives the sliding rod 48, placement frame 47, and other components to rotate around the annular guide rail 42 via the ring 411. During the rotation, the roller 410 contacts the protrusion 43 inside the annular guide rail 42. Since the height of the protrusion 43 is higher than other parts of the annular guide rail 42, the roller... When the roller 410 is lifted, it causes the slide bar 48 to move upward, and the spring 49 is stretched, which in turn causes the placement frame 47 to move upward. When the roller 410 passes the protrusion 43, the slide bar 48 and the placement frame 47 move downward under the elastic force of the spring 49. This process is repeated, causing the particles in the placement frame 47 to continuously tumble up and down, so that they can fully contact the hot air and achieve uniform drying. (Four fixing blocks are fixed on the outside of the rotating rod 45, and the sleeve rod 46 has a matching sliding groove inside, so that the sleeve rod 46 can be driven to rotate by the rotating rod 45, and can also slide on the outside of the rotating rod 45.)
[0029] The striking mechanism 7 includes a mounting plate 71. The right side of the mounting plate 71 is fixedly connected to the left side of the outside of the hopper 6. A moving groove 72 is opened on the top of the mounting plate 71. A motor 73 is fixedly connected inside the mounting plate 71. A gear 74 is fixedly connected to the output end of the motor 73. A gear frame 75 is meshed on the outside of the gear 74. A striking rod 76 is fixedly connected to the right side of the gear frame 75.
[0030] It should be noted that when the motor 73 is started, the motor 73 drives the gear 74 to rotate. Since the gear 74 is half toothed and half toothless, when the toothed part of the gear 74 meshes with the teeth on one side of the gear frame 75, the gear frame 75 moves to the right in the moving groove 72, causing the striking rod 76 to strike the hopper 6. When the teeth of the gear 74 mesh with the teeth on the other side of the gear frame 75, the gear frame 75 moves to the left, and the striking rod 76 leaves the hopper 6. This cycle continues, and the striking rod 76 repeatedly strikes the hopper 6 to prevent the material in the hopper 6 from clumping and to speed up the feeding rate.
[0031] like Figure 4 As shown, one end of the spring 49 is fixedly connected to the bottom of the placement frame 47, and the other end of the spring 49 is fixedly connected to the top of the ring 411.
[0032] It should be noted that the spring 49 provides elastic force for the up-and-down movement of the placement frame 47, so that the placement frame 47 can be smoothly lifted and lowered when it encounters the protrusion 43, ensuring the turning effect of the particles.
[0033] like Figure 3 As shown, the outer side of the ring 411 is rotatably connected to the inside of the mounting frame 41.
[0034] It should be noted that the ring 411 must be able to rotate stably within the mounting frame 41, thereby enabling other components to function normally.
[0035] like Figure 4 As shown, the two rollers 410 and the two protrusions 43 are symmetrically distributed.
[0036] It should be noted that both rollers 410 are in contact with the protrusion 43 simultaneously.
[0037] like Figure 5 As shown, gear 74 is half toothed and half toothless.
[0038] It should be noted that the gear 74 is designed to enable the reciprocating motion of the gear frame 75 when it rotates, thereby allowing the striking rod 76 to periodically strike the hopper 6 to prevent material from clumping.
[0039] like Figure 5 As shown, the outer side of the toothed frame 75 is slidably connected to the inside of the moving groove 72.
[0040] It should be noted that the moving groove 72 limits the movement of the toothed frame 75, ensuring that the toothed frame 75 can move in the correct direction and that the striking rod 76 accurately strikes the hopper 6.
[0041] like Figure 1 As shown, the striking rod 76 and the hopper 6 are in contact.
[0042] It should be noted that the striking rod 76 can effectively transmit the striking force to the hopper 6, thereby preventing the material from clumping.
[0043] The working principle of this utility model is as follows: In the production process of biochar-based fertilizer, the material is first stored in the silo 6. During the material conveying process in the silo 6, the striking mechanism 7 is activated, and the motor 73 drives the gear 74 to rotate. The gear 74 meshes with the toothed frame 75 to drive the striking rod 76 to reciprocate to strike the silo 6 to prevent the material from clumping. The material is conveyed to the disc granulator 2 for granulation by the auger conveyor 5. The granulated particles enter the screening machine 3 for screening. Particles that meet the requirements are conveyed to the drying mechanism 4 as finished products. Particles that do not meet the requirements are returned for re-granulation, thereby realizing the continuous production of biochar-based fertilizer. When the drying mechanism 4 is working, the hot air blower 44 generates hot air. At the same time, the rotating rod 45 and the sleeve rod 46 drive the placement frame 47 to rotate around the annular guide rail 42. Under the action of the protrusion 43 and the spring 49, the particles in the placement frame 47 continuously tumble up and down, making full contact with the hot air to achieve uniform drying.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
