Description

Technical Field

[0001] This invention relates to the technical field of equipment for processing bio-organic fertilizer, specifically to a bio-organic fertilizer granulation equipment and its granulation method. Background Technology

[0002] In the processing of bio-organic fertilizer, appropriate granulation equipment is often required to granulate the fertilizer. Currently, the main equipment used for granulation of bio-organic fertilizer includes disc granulators and screw extruders. Because traditional disc granulators have poor adaptability to high-moisture materials, and because bio-organic fertilizer has relatively high looseness, screw extruders are currently more commonly used for granulation.

[0003] Most existing screw extrusion granulators for bio-organic fertilizer granulation use conventional screw extrusion granulators. These typically include a fixed housing with guide holes and a feeding screw rotatably positioned within the guide holes of the fixed housing. Driven by an external drive mechanism, the feeding screw rotates and extrudes the material entering the guide holes of the fixed housing, causing the material to be extruded into granules after passing through the forming die holes. While the forming efficiency is high, the particle size variation of the material is relatively large, resulting in insufficient granulation uniformity. Furthermore, significant tearing occurs when the material breaks, causing the ends of the granules to easily become loose and fragmented, leading to a high breakage rate in the formed material.

[0004] Therefore, the research objective of this invention is to design a bio-organic fertilizer granulation equipment and granulation method that can effectively ensure the uniformity of material granulation and significantly reduce the breakage rate of granulated material without affecting the granulation efficiency of the material. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a bio-organic fertilizer granulation equipment and granulation method, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A bio-organic fertilizer granulation device, comprising:

[0008] A fixed housing is provided, with at least one corresponding guide hole inside the fixed housing. A hopper communicating with the guide hole is provided on the upper side of the fixed housing. An extrusion screw is rotatably installed at the guide hole. The extrusion screw is driven by a corresponding drive mechanism. An end cover plate with multiple discharge guide holes on its periphery is fixedly installed at the end of the fixed housing.

[0009] The molding assembly includes a molding cover plate that can be oscillatingly mounted on the outside of the end cover plate. The molding cover plate is driven by a corresponding oscillating drive mechanism. The outer end face of the end cover plate is provided with a first molding groove that communicates with the discharge guide hole. The inner end face of the molding cover plate is provided with a second molding groove that is adapted to the first molding groove.

[0010] A multi-functional cutting assembly includes a spring sheet that can be movably inserted into an end cover plate on the upper side of the first forming groove. The inner ends of the spring sheets extend through to the connection between the discharge guide hole and the first forming groove. The outer ends of the spring sheets are respectively fixed with corresponding magnetic metal plates. The magnetic metal plates are respectively fixedly installed to the outer side of the end cover plate by corresponding elastic elements.

[0011] The cutting drive mechanism includes a plurality of magnets fixedly embedded in the forming cover plate, each magnet facing the magnetic metal plate.

[0012] When the forming cover plate swings downwards to fit against the outer end face of the end cover plate, the magnets attract and drive the corresponding magnetic metal plates, the elastic element is compressed, and the spring plate moves away from the connection between the discharge guide hole and the first forming groove; when the forming cover plate swings upwards to move away from the end cover plate, the elastic element restores its deformation and drives the spring plate to return to the connection between the discharge guide hole and the first forming groove, so as to cut the formed spherical material.

[0013] The first forming groove and the second forming groove are both spherical grooves. When the forming cover plate swings downward to fit against the outer end face of the end cover plate, the first forming groove and the second forming groove combine to form an integral spherical forming cavity.

[0014] After the elastic element recovers its deformation to drive the spring sheet to cut the formed spherical material, the subsequently extruded material drives the end of the spring sheet forward, and the end of the spring sheet swings forward to push the formed spherical material away from the first forming groove for dropping.

[0015] The molding cover plate inside the second molding groove is respectively provided with corresponding limiting grooves. The limiting grooves are respectively fixedly installed with arc panels extending into the second molding groove through corresponding buffer rubber parts. After the material is squeezed to fill the spherical molding cavity formed by the second molding groove and the first molding groove, the buffer rubber parts are squeezed to the arc panels located in the corresponding limiting grooves.

[0016] When the molding cover plate swings upward to leave the end cover plate, the buffer rubber component resets and forms an outward driving force on the arc panel to push the molded material away from the second molding groove.

[0017] The drive mechanism includes a drive motor and a reducer that is driven to the output shaft end of the drive motor. The extrusion screw is driven to the output shaft end of the reducer. The swing drive mechanism uses a set of drive cylinders.

[0018] The extrusion end of the extrusion screw can be rotatably mounted to the center of the end cover plate.

[0019] The elastic element is a magnetic metal helical spring, which is fixedly installed to the outside of the end cover plate via a corresponding connecting plate.

[0020] A method for granulating bio-organic fertilizer, based on the aforementioned bio-organic fertilizer granulation equipment, includes the following specific steps:

[0021] S1, the organic fertilizer material enters the guide hole of the fixed housing through the feeding hopper, and the extrusion screw rotates to transport the organic fertilizer material and press it into the discharge guide hole of the end cover plate in a squeezed state.

[0022] S2, the forming cover plate swings downwards to fit against the outer end face of the end cover plate, the magnet attracts and drives the corresponding magnetic metal plate, and the spring sheet leaves the junction of the discharge guide hole and the first forming groove.

[0023] S3, organic fertilizer material is squeezed into the first forming tank and the second forming tank to form granular material;

[0024] S4, the forming cover plate swings upward to leave the end cover plate, the elastic element restores its deformation to drive the spring plate, so that it returns to the connection between the discharge guide hole and the first forming groove, so as to cut the formed spherical material;

[0025] S5, the cut granular material rolls out through the first forming trough for output.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1) Based on an end cover plate with numerous discharge guide holes at its periphery, this invention further adds a forming component, a multi-functional cutting component, and a cutting drive mechanism. The cutting drive mechanism includes several magnets fixedly embedded in the forming cover plate of the forming component. This allows for simultaneous material forming and output, as well as drive control of the cutting drive mechanism, through the flipping of the forming cover plate. During the forming process, the forming cover plate swings downwards to abut against the outer end face of the end cover plate, creating a corresponding forming space between the first and second forming grooves. At this time, the magnets attract and drive the corresponding magnetic metal plates, causing the corresponding spring plates to leave the connection between the discharge guide holes and the first forming groove, facilitating material extrusion. As the material continues to be extruded, it effectively fills the space between the first and second forming grooves for thorough granulation. After granulation, the forming cover plate swings upwards to leave the end cover plate, and the elastic element recovers its deformation, driving the corresponding spring plates back to their original positions at the connection between the discharge guide holes and the first forming groove, thus cutting the formed spherical material.

[0028] In this way, the material can be granulated in a reasonable manner and the granulation uniformity can be effectively ensured, while the breakage rate of the granulated material can be significantly reduced.

[0029] 2) After the elastic element of the present invention recovers its deformation to drive the corresponding spring sheet to cut the shaped spherical material, the subsequently extruded material will drive the end of the spring sheet forward. At this time, the end of the spring sheet will swing forward to push the shaped spherical material away from the first forming groove for dropping, and can also block the subsequently output material to prevent it from leaving the first forming groove. After the dropping is completed, the forming cover plate can swing downward again to fit against the outer end face of the end cover plate, so as to quickly repeat the granulation process of bio-organic fertilizer, thereby effectively ensuring the granulation efficiency of the material.

[0030] 3) The molding cover plate inside the second molding groove of the present invention is respectively provided with corresponding limiting grooves. Arc-shaped panels extending into the second molding groove are fixedly installed outwards within the limiting grooves via corresponding buffer rubber components. After the material is squeezed to fill the spherical molding cavity formed by the second molding groove and the first molding groove, the buffer rubber components are squeezed until the arc-shaped panels are located within the corresponding limiting grooves. This generates a reaction force on the material during the granulation process between the first and second molding grooves, thereby assisting in improving the granulation effect. When the molding cover plate swings upwards to leave the end cover plate, the buffer rubber components reset and generate an outward driving force on the arc-shaped panels, pushing the shaped material away from the second molding groove. This prevents the material from being fixedly embedded in the second molding groove, thus preventing subsequent material discharge from proceeding normally and effectively improving the practical effect of the present invention.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Example 1:

[0040] refer to Figure 1-6 A bio-organic fertilizer granulation device, comprising:

[0041] A fixed housing 1 is provided, and at least one corresponding guide hole 101 is provided inside the fixed housing 1. A feeding hopper 102 communicating with the guide hole 101 is provided on the upper side of the fixed housing 1. An extrusion screw 2 is rotatably installed at the guide hole 101. The extrusion screw 2 is driven by a corresponding driving mechanism 3. An end cover plate 4 with a plurality of discharge guide holes 401 on its periphery is fixedly installed at the end of the fixed housing 1.

[0042] The molding assembly 5 includes a molding cover plate 501 that can be oscillatingly mounted on the outside of the end cover plate 4. The molding cover plate 501 is driven by a corresponding oscillating drive mechanism 502. The outer end face of the end cover plate 4 is provided with a first molding groove 402 that communicates with the discharge guide hole 401. The inner end face of the molding cover plate 501 is provided with a second molding groove 5011 that is adapted to the first molding groove 402.

[0043] The multi-functional cutting assembly 6 includes a spring sheet 601 that is movably inserted into the end cover plate 4 on the upper side of the first forming groove 402. The inner end of the spring sheet 601 extends through to the connection between the discharge guide hole 401 and the first forming groove 402. The outer end of the spring sheet 601 is fixedly connected to a corresponding magnetic metal plate 602. The magnetic metal plate 602 is fixedly installed to the outer side of the end cover plate 4 by a corresponding elastic element 603.

[0044] The cutting drive mechanism 7 includes a plurality of magnets fixedly embedded in the forming cover plate 501, and the magnets are respectively facing the magnetic metal plate 602.

[0045] When the forming cover plate 501 swings downward to fit against the outer end face of the end cover plate 4, the magnets attract and drive the corresponding magnetic metal plates 602, the elastic element 603 is compressed, and the spring plate 601 moves away from the junction of the discharge guide hole 401 and the first forming groove 402; when the forming cover plate 501 swings upward to move away from the end cover plate 4, the elastic element 603 restores its deformation and drives the spring plate 601 to return to the junction of the discharge guide hole 401 and the first forming groove 402, so as to cut the formed spherical material.

[0046] Based on the end cover plate 4 with a plurality of discharge guide holes 401 at its periphery, the present invention further adds a forming component 5, a multi-functional cutting component 6 and a cutting drive mechanism 7. The cutting drive mechanism 7 includes a plurality of magnets fixedly embedded in the forming cover plate 501 of the forming component 5, so that the forming cover plate 501 can be flipped to simultaneously adapt to the forming and output of materials, as well as drive and control the cutting drive mechanism 7. During the molding process, the molding cover plate 501 swings downwards to abut against the outer end face of the end cover plate 4, forming a molding space between the first molding groove 402 and the second molding groove 5011. At this time, the magnets attract and drive the corresponding magnetic metal plates 602, and the corresponding spring plates 601 move away from the junction of the discharge guide hole 401 and the first molding groove 402 to facilitate the extrusion and output of the material. As the material is continuously extruded and output, it can effectively fill the space between the first molding groove 402 and the second molding groove 5011 for sufficient granulation and molding. After granulation and molding, the molding cover plate 501 swings upwards to abut against the end cover plate 4, and the elastic element 603 restores its deformation to drive the corresponding spring plates 601, causing them to return to the junction of the discharge guide hole 401 and the first molding groove 402 to cut the spherical material after molding. In this way, the material can be reasonably granulated and the granulation uniformity of the material can be effectively ensured, and the breakage rate of the granulated material can be significantly reduced.

[0047] The first molding groove 402 and the second molding groove 5011 are spherical grooves with a 1 / 2 spherical shape. When the molding cover plate 501 swings downward to fit against the outer end face of the end cover plate 4, the first molding groove 402 and the second molding groove 5011 combine to form an integral spherical molding cavity.

[0048] After the elastic element 603 recovers its deformation to drive the spring sheet 601 to cut the shaped spherical material, the subsequently extruded material drives the end of the spring sheet 601 forward, and the end of the spring sheet 601 swings forward to push the shaped spherical material away from the first forming groove 402 for dropping.

[0049] After the elastic element 603 of the present invention recovers its deformation to drive the corresponding spring sheet 601 to cut the shaped spherical material, the subsequently extruded material will drive the end of the spring sheet 601 forward. At this time, the end of the spring sheet 601 will swing forward to push the shaped spherical material away from the first forming groove 402 for discharge, and can also block the subsequently output material to prevent the subsequently output material from leaving the first forming groove 402. After the discharge is completed, the forming cover plate 501 can swing downward again to fit against the outer end face of the end cover plate 4, so as to quickly repeat the granulation process of bio-organic fertilizer, thereby effectively ensuring the granulation efficiency of the material.

[0050] The molding cover plate 501 on the inner side of the second molding groove 5011 is respectively provided with corresponding limiting grooves. The limiting grooves are respectively fixedly installed with arc panel 9 extending into the second molding groove 5011 through corresponding buffer rubber parts 8. After the material is squeezed and fills the spherical molding cavity formed by the second molding groove 5011 and the first molding groove 402, the buffer rubber parts 8 are squeezed to the arc panel 9 located in the corresponding limiting groove.

[0051] When the molding cover plate 501 swings upward to leave the end cover plate 4, the buffer rubber component 8 resets and forms an outward driving force on the arc panel 9 to push the molded material away from the second molding groove 5011.

[0052] The molding cover plate 501 on the inner side of the second molding groove 5011 of the present invention is respectively provided with corresponding limiting grooves. Arc-shaped panels 9 extending into the second molding groove 5011 are fixedly installed outwards within the limiting grooves via corresponding buffer rubber parts 8. After the material is squeezed and fills the spherical molding cavity formed by the second molding groove 5011 and the first molding groove 402, the buffer rubber parts 8 are squeezed until the arc-shaped panels 9 are located within the corresponding limiting grooves. This creates a reaction force on the material during the granulation process between the first molding groove 402 and the second molding groove 5011, thereby assisting in improving the granulation effect. When the molding cover plate 501 swings upwards to leave the end cover plate 4, the buffer rubber parts 8 reset and generate an outward driving force on the arc-shaped panels 9, pushing the shaped material away from the second molding groove 5011. This prevents the material from being fixedly embedded in the second molding groove 5011, thus preventing subsequent material discharge from proceeding normally and effectively improving the practical effect of the present invention.

[0053] The drive mechanism 3 includes a drive motor 301 and a reducer 302 that is driven to the output shaft end of the drive motor 301. The extrusion screw 2 is driven to the output shaft end of the reducer 302. The swing drive mechanism 502 adopts a set of drive cylinders.

[0054] The extrusion end of the extrusion screw 2 is rotatably mounted to the center of the end cover plate 4. The elastic element 603 is a magnetic metal helical spring, which is fixedly mounted to the outside of the end cover plate 4 via a corresponding connecting plate 10.

[0055] Example 2:

[0056] A method for granulating bio-organic fertilizer, based on the bio-organic fertilizer granulation equipment described in Embodiment 1 above, includes the following specific steps:

[0057] S1, the organic fertilizer material enters the guide hole 101 of the fixed housing 1 through the feeding hopper 102, and the extrusion screw 2 rotates to transport the organic fertilizer material and press it into the discharge guide hole 401 of the end cover plate 4 in a squeezed state.

[0058] S2, the forming cover plate 501 swings downward to fit against the outer end face of the end cover plate 4, the magnet drives the corresponding magnetic metal plate 602 to be attracted, and the spring plate 601 leaves the junction of the discharge guide hole 401 and the first forming groove 402.

[0059] S3, organic fertilizer material is squeezed into the first forming tank 402 and the second forming tank 5011 to form granular material;

[0060] S4, the forming cover plate 501 swings upward to leave the end cover plate 4, the elastic element 603 restores its deformation to drive the spring plate 601, so that it returns to the connection between the discharge guide hole 401 and the first forming groove 402, so as to cut the formed spherical material.

[0061] S5, the cut granular material rolls out through the first forming groove 402 for output.

[0062] In the granulation process of the bio-organic fertilizer according to Example 2 of the present invention, the granulation efficiency is relatively high, and it can effectively ensure the uniformity of material granulation and effectively reduce the breakage rate of the granulated material, thereby effectively ensuring the quality of the granulated bio-organic fertilizer.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
