Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer production, in particular to granulation equipment and a granulation method for fermented sheep manure. Background Art

[0002] A large amount of feces will be produced during sheep breeding. Sheep manure itself is rich in organic matter. How to effectively utilize it as a resource is a problem that needs to be solved urgently. Sheep manure is aerobic fermented to produce organic fertilizer, which is finally returned to the field. It is a very effective utilization channel. The existing organic fertilizer granulation equipment mainly includes disc granulation and drum granulation. The disc granulator is generally composed of a granulating disc, a driving device, a disc inclination adjustment mechanism, a frame, a feeding pipe, a liquid sprayer, and a hanging plate. The fertilizer fine particles are placed on a disc with a certain inclination, and a certain amount of adhesive solution is sprayed into the fine particles. The disc can form the fine particles of fertilizer into spherical particles during rotation; the principle of drum granulation is that the material relies on surface tension, an appropriate amount of liquid phase, the extrusion force generated by the rolling of the materials, and the correct movement direction of the material in the granulator. The small particles are taken as the core, and the large particles are absorbed and attached to the small particles during rolling and bonded into balls. Therefore, both disc granulation and drum granulation require the adjustment of moisture and the addition of a binder to form granules. For herbivorous animals such as sheep, their feces contain a large amount of plant fiber, which makes it difficult to form, and thus it is difficult to use disc granulation and drum granulation methods for granulation. In addition, the spherical organic fertilizer particles made by disc granulation and drum granulation have a high degree of compaction and slow fertilizer release, which is not conducive to the utilization of organic fertilizer efficiency. In addition, in the existing disc granulation and drum granulation processes, the temperature rise is small, which is not enough to kill the residual pathogens in the organic fertilizer. Summary of the invention

[0003] The purpose of the present invention is to provide a granulation device and a granulation method for fermented sheep manure to solve the above problems existing in the prior art.

[0004] In order to solve the above technical problems, the technical solution of the present invention is:

[0005] The present invention provides a granulation device for fermenting sheep manure, comprising a feed hopper, a granulation chamber and a power transmission mechanism, wherein the feed hopper is arranged above the granulation chamber and is communicated with the granulation chamber; a pressure roller assembly, a die plate and a throwing plate are sequentially arranged in the granulation chamber from top to bottom, the pressure roller assembly comprises a first pressure roller and a second pressure roller connected by a central axis, the first pressure roller and the second pressure roller are symmetrically installed above the die plate, and a set distance is reserved from the upper surface of the die plate, and both ends of the central axis are installed on the inner wall of the granulation chamber through a gap adjustment device, the gap adjustment device comprises a first adjustment block, a second adjustment block, a first adjustment bolt and a second adjustment bolt, the first adjustment block and the second adjustment block are both hollow structures and are respectively fixed on the inner wall of the granulation chamber, and the upper ends of the first adjustment block and the second adjustment block are respectively processed with a first through hole and a second through hole, The first through hole and the second through hole are respectively communicated with the hollow structure part, the upper end of the first adjusting bolt is cooperated with the first nut, and the lower end is fixedly connected to one end of the central axis after passing through the first through hole, the upper end of the second adjusting bolt is cooperated with the second nut, and the lower end is fixedly connected to the other end of the central axis after passing through the second through hole, the die plate is provided with a keyway and a die hole, an angle-adjustable cutter is installed between the die plate and the throwing plate, a discharge hopper is provided below the granulation chamber, and the discharge hopper is correspondingly provided with the throwing plate, an annular plate body is horizontally provided at the bottom of the throwing plate, and the inner side of the annular plate body is connected to the bottom of the throwing plate, so that the movement direction of the granular material rolling down from the throwing plate is changed to a horizontal direction; the power transmission mechanism is respectively connected to the throwing plate and the die plate to drive the throwing plate and the die plate to rotate.

[0006] Furthermore, the power transmission mechanism includes a motor, a coupling, a gear box and a main shaft which are connected in sequence, the main shaft is connected to the throwing disc and the mold disc respectively, and the main shaft, the throwing disc and the mold disc are coaxially arranged.

[0007] The motor drives the gearbox through the coupling, and the gearbox drives the main shaft to rotate, and then drives the die plate to rotate through the main shaft. The rotation of the die plate drives the fermented sheep manure material in the granulation chamber to move, and the fermented sheep manure material transmits power to the roller assembly, thereby driving the first roller and the second roller to rotate around the central axis. Since the first roller and the second roller are fixed inside the granulation chamber through the central axis, when the die plate rotates, the first roller and the second roller simultaneously realize the revolution relative to the die plate. The rotation of the first roller and the second roller, as well as the revolution relative to the die plate, can realize the extrusion of the fermented sheep manure material in the granulation chamber. Under the extrusion, the sheep manure material is formed and falls through the die hole on the die plate. The formed sheep manure material is cut to a fixed length by a cutter under the die plate to obtain a semi-column (a cylindrical granule with the same particle height and diameter) or a flat columnar granule.

[0008] The cut particles fall on the throwing disc. Since the throwing disc is in the shape of a cone and rotates continuously, the particles falling on the surface of the throwing disc roll down on the surface of the throwing disc, and are thrown to the discharge hopper under the action of the friction force on the surface of the throwing disc, and then flow out from the discharge hopper.

[0009] The position of the discharge hopper is determined according to factors such as the rotation speed of the cutter and the throwing disc to ensure that the granular material thrown from the throwing disc falls into the discharge hopper.

[0010] The hollow structure of the first adjustment block and the second adjustment block is used to accommodate the two ends of the central axis. By adjusting the length of the first adjustment bolt and the second adjustment bolt between the central axis and the nut, the height of the central axis in the adjustment block is adjusted, thereby adjusting the distance between the pressure roller and the mold plate.

[0011] Furthermore, threaded holes are processed on the mold plate and the main shaft, and the threaded holes cooperate with bolts to fix the mold plate on the main shaft.

[0012] Furthermore, the cutter cuts the formed sheep manure material into fixed lengths to obtain cylindrical granules or flat columnar granules with the same particle height and diameter.

[0013] Furthermore, the distance between the first pressing roller and the second pressing roller and the surface of the mold plate is 0.1-1 mm.

[0014] Furthermore, the cutter is mounted on the side wall of the granulation chamber by bolts. A blade is processed on the cutter, and when the formed columnar material is cut, the powder discharge rate of the particles can be reduced.

[0015] Furthermore, the number of the cutters is 1-3.

[0016] Furthermore, the ratio of the height to the diameter of the die hole is 4 to 5. The compression ratio of the die plate can be adjusted by adjusting the ratio of the height to the diameter of the die hole.

[0017] The present invention also provides a method for granulating fermented sheep manure, which uses the granulating device for fermented sheep manure and comprises the following steps:

[0018] The motor drives the gearbox through the coupling, and the gearbox drives the main shaft to rotate, and then drives the die plate to rotate through the main shaft. The rotation of the die plate drives the fermented sheep manure material in the granulation chamber to move, and the fermented sheep manure material transmits power to the pressing roller assembly, and then drives the first pressing roller and the second pressing roller to rotate around the central axis. Since the first pressing roller and the second pressing roller are fixed inside the granulation chamber through the central axis, when the die plate rotates, the first pressing roller and the second pressing roller simultaneously realize the revolution relative to the die plate. The rotation of the first pressing roller and the second pressing roller and the revolution relative to the die plate can realize the extrusion of the fermented sheep manure material in the granulation chamber. Under the extrusion action, the sheep manure material is formed and falls through the die hole on the die plate, and the formed sheep manure material is cut to a fixed length by the cutter under the die plate to obtain cylindrical granules or flat columnar granules with the same particle height and particle diameter. During the extrusion process, the temperature of the sheep manure material can reach above 60°C, thereby further killing the pathogens in the sheep manure.

[0019] The cut granular materials fall on the throwing disc and rotate continuously. The granular materials falling on the surface of the throwing disc roll downward on the surface of the throwing disc and are thrown toward the discharge hopper under the action of the friction force on the surface of the throwing disc. The horizontally arranged annular plate can change the movement direction of the granular materials rolling down from the throwing disc to the horizontal direction, so as to throw the granular materials horizontally to the discharge hopper for discharge; wherein, the position of the discharge hopper is determined according to the rotation speed of the cutter and the throwing disc, so as to ensure that the granular materials thrown from the throwing disc fall into the discharge hopper.

[0020] Compared with the prior art, the beneficial technical effects of the present invention are:

[0021] 1. The granulation equipment and granulation method of fermented sheep manure of the present invention are aimed at granulating materials after sheep manure fermentation, with high efficiency and good effect, and the particles are semi-column or flat columnar, which has lower density and faster fertilizer release than the existing round granular organic fertilizer, and is conducive to the use and promotion of organic fertilizer.

[0022] 2. The fermented sheep manure granulation equipment and granulation method of the present invention are designed for sheep manure fermentation granulation, and a small compression ratio die plate is designed. Under the premise of molding, the particle density can be reduced, thereby accelerating the release of the particle fertilizer effect.

[0033] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 3 As shown, the granulation equipment for fermented sheep manure of this embodiment 1 includes a feed hopper 4, a granulation chamber 5 and a power transmission mechanism, wherein the feed hopper 4 is arranged above the granulation chamber 5 and is communicated with the granulation chamber 5.

[0036] The granulation chamber 5 is provided with a pressure roller assembly, a die plate 7 and a throwing plate 18, wherein the pressure roller assembly is located above the die plate 7, and the throwing plate 18 is located below the die plate 7. A cutter 8 is provided between the throwing plate 18 and the die plate 7, and the cutter 8 is processed with a blade and fixed to the side wall of the granulation chamber 5 by bolts. The number of the cutters 8 is 1-3, such as 1, 2 or 3. The installation angle of the cutter 8 is adjustable, so as to adjust the particle discharge length. A base frame 11 is provided below the granulation chamber 5.

[0037] like Figure 2 As shown, the die plate 7 is provided with a keyway 13 and a die hole 12, the ratio of the height h of the die hole to the diameter d of the die hole is 4-5, the thickness of the die plate is T, the number of the die holes 12 is 280-310, such as 280, 290, 295, 300, 305 or 310, etc., the throwing plate 18 is truncated cone-shaped, and an annular plate body is horizontally arranged at the bottom, and the inner side of the annular plate body is connected to the bottom of the throwing plate 18, so that the movement direction of the granular material rolling down from the throwing plate 18 is changed to a horizontal direction, so as to facilitate the horizontal throwing of the granular material to the discharge hopper 10 for discharge.

[0038] Specifically, the pressing roller assembly includes a first pressing roller 6 and a second pressing roller connected by a central axis. The first pressing roller 6 and the second pressing roller are symmetrically installed above the mold plate 7, and a set distance is reserved from the upper surface of the mold plate 7. The distance is 0.1-1mm, such as 0.1mm, 0.5mm or 1mm.

[0039] In addition, the two ends of the central axis are mounted on the inner wall of the granulation chamber 5 through a gap adjustment device 9. The gap adjustment device 9 includes a first adjustment block 15, a second adjustment block, a first adjustment bolt and a second adjustment bolt 16. The first adjustment block 15 and the second adjustment block are both hollow structures and are respectively fixed on the inner wall of the granulation chamber 5. The upper ends of the first adjustment block 15 and the second adjustment block are respectively processed with a first through hole and a second through hole, and the through holes are connected to the hollow structure part; the first adjustment bolt passes through the first through hole, and its lower end is fixedly connected to one end of the central axis, and its upper end is matched with the first nut; the second adjustment bolt 16 passes through the second through hole, and its lower end is fixedly connected to the other end of the central axis, and its upper end is matched with the second nut. The first adjustment block 15 and the second adjustment block are fixed on the cavity wall of the granulation chamber 5, and the two end shaft heads of the central axis can move vertically in the adjustment block. By changing the vertical position of the adjustment bolt, the vertical height of the pressure roller shaft in the adjustment block can be adjusted, thereby realizing the vertical height change of the pressure roller and adjusting the gap between the pressure roller and the die plate 7.

[0040] Meanwhile, a discharge hopper 10 is arranged below the granulation chamber 5 , and the discharge hopper 10 is arranged corresponding to the throwing plate 18 .

[0041] In this embodiment 1, the power transmission mechanism includes a motor 1, a coupling 2, a gear box 3 and a main shaft 17 connected in sequence. The main shaft 17 is respectively connected to the throwing plate 18 and the mold plate 7, and the main shaft 17, the throwing plate 18 and the mold plate 7 are coaxially arranged. The mold plate 7 and the main shaft 17 are both machined with threaded holes 14, and the threaded holes 14 cooperate with bolts to fix the mold plate 7 on the main shaft 17.

[0042] When the granulation equipment of fermented sheep manure of the present embodiment 1 is in use, the motor 1 drives the gear box 3 to move through the coupling 2, and the gear box 3 drives the main shaft 17 to rotate, and then drives the die plate 7 to rotate through the main shaft 17. The rotation of the die plate 7 drives the fermented sheep manure material in the granulation chamber 5 to move, and transmits power to the roller assembly through the fermented sheep manure material, thereby driving the first roller 6 and the second roller to rotate around the central axis. Since the first roller 6 and the second roller are fixed inside the granulation chamber 5 through the central axis, when the die plate 7 rotates, the first roller 6 and the second roller are simultaneously realized relative to the die plate 7. The rotation of the first roller 6 and the second roller, as well as the revolution relative to the die plate 7, can realize the extrusion of the fermented sheep manure material in the granulation chamber 5. Under the extrusion, the sheep manure material is formed and falls through the die hole 12 on the die plate 7. The cutter 8 below the die plate 7 is used to cut the formed sheep manure material to a fixed length to obtain a semi-column (a cylindrical granule with the same particle height and particle diameter) or a flat columnar granule. During the extrusion process, the temperature of the sheep manure material can reach above 60°C, which can further kill the pathogens in the sheep manure.

[0043] The cut granular material falls on the throwing disc 18. Since the throwing disc 18 is truncated cone-shaped and rotates continuously, the granular material falling on the surface of the throwing disc 18 rolls downward on the surface of the throwing disc 18, and is thrown toward the discharge hopper 10 under the action of the friction force on the surface of the throwing disc 18, and then flows out from the discharge hopper 10.

[0044] The position of the discharge hopper 10 is determined according to factors such as the rotation speed of the cutter 8 and the throwing disc 18 to ensure that the granular material thrown from the throwing disc 18 falls into the discharge hopper 10 .

[0045] Example 2

[0046] The granulation method of fermented sheep manure in this embodiment 2 adopts the granulation equipment of fermented sheep manure, and comprises the following steps:

[0047] The motor 1 drives the gear box 3 through the coupling 2, and the gear box 3 drives the main shaft 17 to rotate, and then drives the die plate 7 to rotate through the main shaft 17. The rotation of the die plate 7 drives the fermented sheep manure material in the granulation chamber 5 to move, and the fermented sheep manure material transmits power to the roller assembly, thereby driving the first roller 6 and the second roller to rotate around the central axis. Since the first roller 6 and the second roller are fixed inside the granulation chamber 5 through the central axis, when the die plate 7 rotates, the first roller 6 and the second roller are simultaneously realized relative to the die plate 7. The rotation of the first roller 6 and the second roller and the revolution relative to the die plate 7 can realize the extrusion of the fermented sheep manure material in the granulation chamber 5. Under the extrusion action, the sheep manure material is formed and falls through the die hole 12 on the die plate 7, and the formed sheep manure material is cut to a fixed length by the cutter 8 under the die plate 7 to obtain cylindrical granules or flat columnar granules with the same particle height and particle diameter. During the extrusion process, the temperature of the sheep manure material can reach above 60°C, thereby further killing the pathogens in the sheep manure.

[0048] The cut granular material falls on the throwing disc 18 and rotates continuously. The granular material falling on the surface of the throwing disc 18 rolls downward on the surface of the throwing disc 18 and is thrown toward the discharge hopper 10 under the action of the friction force on the surface of the throwing disc 18. The horizontally arranged annular plate can change the movement direction of the granular material rolling down from the throwing disc 18 to a horizontal direction, so as to throw the granular material horizontally into the discharge hopper 10 for discharge; wherein, the position of the discharge hopper 10 is determined according to the rotation speed of the cutter 8 and the throwing disc 18, so as to ensure that the granular material thrown from the throwing disc 18 falls into the discharge hopper 10.

[0049] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
