Technical Field

[0001] This utility model relates to the field of bio-organic fertilizer processing technology, and in particular to a bio-organic fertilizer rapid sterilization and drying device. Background Technology

[0002] Bio-organic fertilizer is an organic fertilizer made from organic solid waste (including organic garbage, straw, human, animal and poultry manure, oilseed cake, agricultural by-products and solid waste generated from food processing) through microbial fermentation, deodorization and complete decomposition. The processing of bio-organic fertilizer includes fermentation, batching, crushing, mixing, granulation, spheroidizing, sterilization and drying, cooling, screening, coating and packaging. Rapid sterilization and drying equipment is required in the sterilization and drying process.

[0003] Uneven distribution of fertilizer within the drying chamber affects the uniform transfer of heat, causing some fertilizer to fail to receive sufficient heat and thus fail to achieve the expected sterilization effect. Some pathogens or harmful microorganisms may survive, which not only affects the quality of the fertilizer.

[0004] Therefore, in response to the problem that the fertilizer is unevenly distributed in the drying chamber, which affects the uniform transfer of heat and makes it impossible for some fertilizer to receive enough heat, thus failing to achieve the expected sterilization effect, a rapid sterilization and drying device is needed to solve the above problems. Utility Model Content

[0005] To address the problem in existing technologies where fertilizer distribution within the drying chamber is uneven, affecting heat transfer and preventing some fertilizer from receiving sufficient heat to achieve the desired sterilization effect, this application provides a rapid sterilization and drying device for bio-organic fertilizers. A first motor drives a rotating rod, which in turn drives a rotating shaft via a transmission assembly. The rotating rod and shaft then drive a stirring plate. During stirring, a hot air furnace is activated, sending hot air through a conveying pipe into the rotating block. The rotating block then uses the hot air outlet for sterilization and drying, resulting in more uniform heat transfer, faster moisture evaporation, increased sterilization and drying speed, shorter sterilization and drying time, and improved production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rapid sterilization and drying device for bio-organic fertilizer includes: a heating barrel serving as the drying body; a protective box fixedly connected to the right end of the heating barrel; a first motor fixedly connected to the right end of the protective box; a rotating rod fixedly connected to the drive end of the first motor through the protective box; a rotating shaft connected to the rotating rod via a transmission assembly; stirring plates fixedly connected to the outer walls of both the rotating rod and the rotating shaft; rotating blocks rotatably connected to the outer walls of both the rotating rod and the rotating shaft; a conveying pipe fixedly connected to the opposite end of the rotating block; a hot air furnace fixedly connected to the bottom end of the conveying pipe; the bottom end of the hot air furnace fixedly connected to the top end of the protective box; and an anti-clogging component provided at the bottom end of the heating barrel.

[0008] As a further improvement of this utility model, the transmission assembly includes gears located on the outer wall of the rotating rod and gears located on the outer wall of the rotating shaft, and the gears are meshed together.

[0009] As a further improvement of this utility model, the inner walls of the rotating rod and the rotating shaft are provided with air outlets, and the inner walls of the rotating rod and the rotating shaft are provided with air inlets corresponding to the positions of the rotating blocks.

[0010] As a further improvement of this utility model, the outer walls of both the rotating rod and the rotating shaft are rotatably connected to the inner wall of the heating barrel.

[0012] As a further improvement of this utility model, a discharge port is fixedly connected to the bottom end of the heating barrel, and a control valve is provided on the outer wall of the discharge port.

[0013] As a further improvement of this utility model, the anti-blocking component includes a connecting frame fixedly connected to the bottom of the heating barrel, a sliding rod slidably connected to the inner wall of the connecting frame, a limiting plate fixedly connected to the bottom end of the sliding rod, a spring provided between the limiting plate and the inner wall of the connecting frame, a plurality of insert rods fixedly connected to the outer wall of the sliding rod, a connecting plate fixedly connected to the front end of the connecting frame, a second motor fixedly connected to the front end of the connecting plate, the drive end of the second motor passing through the connecting plate and fixedly connected to a rotating roller, and a cam fixedly connected to the rear end of the rotating roller.

[0030] Reference Figure 1 - Figure 3Example 1: A rapid sterilization and drying device for biological organic fertilizer, comprising: a heating tank 1 serving as the drying body; a protective box 2 fixedly connected to the right end of the heating tank 1; a first motor 3 fixedly connected to the right end of the protective box 2; a rotating rod 4 fixedly connected to the driving end of the first motor 3 passing through the protective box 2; a rotating shaft 6 connected to the rotating rod 4 via a transmission assembly; stirring plates 7 fixedly connected to the outer walls of both the rotating rod 4 and the rotating shaft 6; rotating blocks 9 rotatably connected to the outer walls of both the rotating rod 4 and the rotating shaft 6; and a fixed connection at one end of each rotating block 9. A conveying pipe 10 is provided, and a hot air furnace 11 is fixedly connected to the bottom end of the conveying pipe 10. The bottom end of the hot air furnace 11 is fixedly connected to the top end of the protective box 2. An anti-blocking component is provided at the bottom end of the heating barrel 1. Air outlets 8 are provided on the inner walls of the rotating rod 4 and the rotating shaft 6. Air inlets 12 are provided on the inner walls of the rotating rod 4 and the rotating shaft 6 at the positions corresponding to the rotating block 9. The outer walls of the rotating rod 4 and the rotating shaft 6 are rotatably connected to the inner wall of the heating barrel 1. A feeding port 13 is fixedly connected to the top end of the heating barrel 1. A cover plate 14 is threadedly connected to the outer wall of the feeding port 13.

[0031] Specifically, the bio-organic fertilizer is poured into the heating tank 1 through the feeding port 13. Then, the cover plate 14 is lifted and fitted tightly into the feeding port 13. At this point, the heating tank 1 is started to heat. The heating tank 1 is generally made of heat-resistant materials such as stainless steel or aluminum, and has an external insulation layer to reduce heat loss. The internal space is heated directly by heating pipes. Then, the first motor 3 is turned on, and the motor's drive end rotates, causing the rotating rod 4 to rotate. As the rotating rod 4 rotates, the transmission assembly causes the rotating shaft 6 to rotate as well. During the rotation of the rotating rod 4 and the rotating shaft 6... The stirring plate 7 stirs the bio-organic fertilizer in the heating tank 1. At the same time, the hot air furnace 11 is turned on. The hot air furnace 11 heats the air through the electric heating element, and then the hot air is discharged by the internal fan. The hot air enters the rotating block 9 through the conveying pipe 10, and then enters the interior of the rotating shaft 6 and the rotating rod 4 through the air inlet 12. Finally, it is discharged from the air outlet 8 to sterilize and dry the bio-organic fertilizer. This design allows the heat to be transferred more evenly, greatly accelerates the evaporation of moisture, effectively improves the sterilization and drying speed, and thus shortens the entire sterilization and drying time, significantly improving production efficiency.

[0032] Reference Figure 1 and Figure 4The bottom of the heating barrel 1 is fixedly connected to a discharge port 15. A control valve 16 is provided on the outer wall of the discharge port 15. The anti-blocking component includes a connecting frame 17 fixedly connected to the bottom of the heating barrel 1. A slide rod 18 is slidably connected to the inner wall of the connecting frame 17. A limit plate 20 is fixedly connected to the bottom of the slide rod 18. A spring 21 is provided between the limit plate 20 and the inner wall of the connecting frame 17. Multiple insert rods 19 are fixedly connected to the outer wall of the slide rod 18. A connecting plate 22 is fixedly connected to the front end of the connecting frame 17. A second motor 23 is fixedly connected to the front end of the connecting plate 22. The drive end of the second motor 23 passes through the connecting plate 22 and is fixedly connected to a rotating roller 24. A cam 25 is fixedly connected to the rear end of the rotating roller 24. One end of the spring 21 is connected to the limit plate 20, and the other end of the spring 21 is connected to the inner wall of the connecting frame 17.

[0033] Specifically, starting from the feeding stage, the control valve 16 is opened, and the sterilized and dried bio-organic fertilizer will be discharged from the feeding port 15 into the heating tank 1. At this time, the second motor 23 is started, and the motor drives the rotating roller 24 to rotate. The rotating roller 24, in turn, drives the cam 25 connected to it to rotate together. When the cam 25 rotates to the point where the convex surface faces upward, it will push the limiting plate 20 upward. The limiting plate 20 moves under force, which in turn drives the slide rod 18 to move synchronously. When the slide rod 18 moves, the insertion rod 19 connected to one end of it moves accordingly. The insertion rod 19 will poke the organic fertilizer that is being discharged, thus... The operation can effectively avoid material blockage during the discharge process, prevent material accumulation, ensure continuous production, greatly reduce downtime caused by blockage, and significantly improve production efficiency. As the cam 25 continues to rotate, when the convex surface leaves the contact position with the limit plate 20 and rotates to the point where the round surface faces upward, the spring 21 installed between the limit plate 20 and the fixed position of the equipment will play a role, pushing the limit plate 20 back to its original position. At the same time as the limit plate 20 resets, it also drives the slide rod 18 to reset, preparing for the next cam 25 pushing operation.

[0034] Example 2: As one of the optimized structural designs of Example 1, such as Figure 1 and Figure 2 As shown, the transmission assembly includes gears 5 located on the outer wall of the rotating rod 4 and on the outer wall of the rotating shaft 6, and the gears 5 are meshed together.

[0035] Specifically, when the rotating rod 4 starts to rotate, it will drive the right gear 5 connected to it to rotate synchronously. Since the right gear 5 and the left gear 5 mesh with each other, the rotation of the right gear 5 drives the left gear 5 to rotate as well. The left gear 5 is closely connected to the rotating shaft 6, so when the left gear 5 rotates, the rotating shaft 6 also rotates. The rotation of the rotating rod 4 and the rotating shaft 6 causes the stirring plate 7 fixed on them to move together, thereby fully stirring the biological organic fertilizer in the heating tank and ensuring that the fertilizer is heated evenly during the drying and sterilization process.

[0036] Working Principle: First, the bio-organic fertilizer is placed into the heating tank 1 through the feeding port 13. After placement, the cover plate 14 is lifted to align with the feeding port 13. The heating tank 1 is then activated to heat the fertilizer. The heating tank 1 is typically made of heat-resistant materials such as stainless steel or aluminum, and may be equipped with an external insulation layer to prevent heat loss. The interior of the heating tank 1 is directly heated by heating pipes. Then, the first motor 3 is activated, causing the drive end to rotate, which in turn rotates the rotating rod 4. The rotating rod 4 rotates, driving the right gear 5, which in turn rotates the left gear 5, which in turn rotates the rotating shaft 6. The rotation of the rotating rod 4 and shaft 6 simultaneously drives the stirring plate 7 to stir the bio-organic fertilizer. While stirring, the hot air furnace 11 is turned on, sending hot air through the conveying pipe 10 into the rotating block 9. The rotating block 9 then sends the hot air through the air inlet 12 into the rotating shaft 6 and rotating rod 4. The hot air is then discharged through the air outlet 8, thus stimulating the bio-organic fertilizer. The fertilizer undergoes sterilization and drying to ensure more uniform heat transfer, accelerate moisture evaporation, increase sterilization and drying speed, shorten sterilization and drying time, and improve production efficiency. The hot air furnace 11 heats the air through electric heating elements, and then uses an internal fan to exhaust the hot air. When feeding, the control valve 16 is opened so that the sterilized and dried organic fertilizer is discharged from the feeding port 15 into the heating tank 1. At this time, the second motor 23 is started to drive the rotating roller 24 to rotate. When the rotating roller 24 rotates, it drives the cam 25 to rotate. When the cam 25 rotates to the convex surface, it will push the limit plate 20. When the limit plate 20 moves, it drives the slide rod 18 to move. When the slide rod 18 moves, it drives the insert rod 19 to poke the organic fertilizer to avoid blockage, effectively prevent material accumulation, ensure continuous operation, reduce downtime caused by blockage, and improve production efficiency. When the cam 25 rotates to the circular surface, the spring 21 will bounce the limit plate 20. When the limit plate 20 is bounced, it drives the slide rod 18 to reset.
