Description

Technical Field

[0001] This utility model relates to the field of bio-organic fertilizer production technology, specifically a cooling device for bio-organic fertilizer production. Background Technology

[0002] In the production of bio-organic fertilizer, the cooling process is one of the key steps to ensure product quality. After high-temperature fermentation, the organic fertilizer material needs to be cooled to a suitable temperature before subsequent screening, packaging, and storage. This is to prevent secondary fermentation, mold growth, or nutrient loss due to excessively high temperatures. Therefore, a dedicated cooling device is required to cool the organic fertilizer material.

[0003] For example, a cooling device for the production and processing of granular bio-organic fertilizer, as disclosed in Chinese Patent Publication No. CN220582918U, includes a stirring drum. A support plate is fixedly installed at the bottom of the stirring drum. An air inlet pipe is connected to the center of the stirring drum, and a rotating column is rotatably connected to the bottom of the air inlet pipe. The rotating column is hollow, and its internal cavity communicates with the air inlet pipe. Spiral blades are fixedly connected to the surface of the rotating column, and ventilation chambers are formed inside the spiral blades. This invention utilizes spiral blades with ventilation holes, allowing for large-area contact between the spiral blades and the granular organic fertilizer. While rotating, external gas is introduced through the ventilation holes at the bottom of the spiral blades for cooling, resulting in rapid cooling. When all the organic fertilizer inside is discharged, a small amount of organic fertilizer may remain. At this point, a strong gas flow through the air inlet pipe can blow off the remaining organic fertilizer, eliminating the need for manual cleaning.

[0004] Although the above technical solution has the above technical advantages, its disadvantage is that the above solution only introduces external gas through the air vent at the bottom of the spiral blade for cooling. However, during the heat exchange process, the heat transferred from the material to the relevant parts of the equipment is difficult to be carried away quickly and fully by the airflow. The range of hot air collection is limited, and the heat is not completely discharged, which restricts the overall cooling effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for the production of bio-organic fertilizer, which solves the problem of slow heat dissipation when materials are transferred to relevant equipment components.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a cooling device for bio-organic fertilizer production, comprising a protective shell, a feeding hopper fixedly connected to the outer side of the protective shell, a telescopic cylinder fixedly connected to the bottom of the feeding hopper, a baffle fixedly connected to the bottom end of the telescopic cylinder, and a discharge hopper slidably connected to the outer wall of the baffle; further comprising: a material receiving box fixedly connected to the inner side of the protective shell, heat dissipation fins fixedly connected to the outer side of the material receiving box, an air guide pipe fixedly connected to the inner wall of the heat dissipation fins, an air guide shell fixedly connected to the bottom of the material receiving box, a dust cover fixedly connected to the bottom of the air guide shell, a drive motor fixedly connected to the bottom of the dust cover, a rotating component fixedly connected to the output end of the drive motor, a heat dissipation cover fixedly connected to the top of the dust cover, a centrifugal fan at the bottom of the rotating shaft rotating with the rotating shaft inside the air guide shell, drawing outside cold air into the air guide shell through the dust cover, and the cold air entering the air guide pipe through the air guide shell under the action of centrifugal force; when the airflow passes rapidly through the air guide pipe, the air guide pipe is in a negative pressure state.

[0007] The rotating component includes a rotating shaft, a centrifugal fan fixedly connected to the bottom of the rotating shaft, a feeding plate fixedly connected to the outer wall of the rotating shaft, a lifting plate fixedly connected to the top of the feeding plate, and an air suction fan fixedly connected to the top of the rotating shaft. The lifting plate can convey the material upward along the side wall of the receiving box, and the top of the lifting plate is inclined downward so that the material can fall smoothly after being conveyed to a certain height, increasing the contact area between the material and the air, and making the cooling more uniform.

[0008] Preferably, the outer wall of the discharge hopper is fixedly connected to the side wall of the protective shell, the heat dissipation fins are arranged linearly along the central axis of the receiving box, and both the feed hopper and the discharge hopper extend to the inner side of the receiving box. The bio-organic fertilizer to be cooled can enter the receiving box from the feed hopper outside the protective shell.

[0009] Preferably, the air guide pipes are arranged in a ring along the central axis of the heat dissipation fins, and the bottom end of the air guide pipes is fixedly connected to the top of the air guide shell. The heat of the high-temperature material in the material box is transferred to the heat dissipation fins on the outside. The heat absorbed by the heat dissipation fins causes the surrounding air to heat up and form hot air. This hot air is drawn into the air guide pipes under the action of negative pressure.

[0010] Preferably, the outer wall of the rotating shaft is rotatably connected to the center of the material receiving box, the bottom end of the rotating shaft is fixedly connected to the output end of the drive motor, the centrifugal fan is located inside the air guide shell, the suction fan is located inside the heat dissipation shroud, the top end of the rotating shaft is rotatably connected to the center of the heat dissipation shroud, and the suction fan at the top end of the rotating shaft rotates with the rotating shaft inside the heat dissipation shroud, generating an upward suction force. This suction force not only draws the air in the air guide pipe upward to assist its discharge, but also allows the hot air in the material receiving box to be discharged outside the device through the heat dissipation shroud.

[0011] Preferably, a horn cover is fixedly connected to the outer wall of the air guide pipe, and the horn cover is linearly arranged along the central axis of the air guide pipe. An air inlet is opened in the wall of the air guide pipe. The top end of the air guide pipe is fixedly connected to the bottom of the heat sink. The horn cover is in an outward expanding shape. Under the action of negative pressure in the air guide pipe, hot air in a larger range around the air inlet can be gathered and guided to the air inlet, further expanding the range of hot air collection and facilitating the discharge of heat from the heat sink fins.

[0012] The beneficial effects of this utility model are as follows:

[0013] (i) The device is equipped with heat dissipation fins. When the airflow passes through the air duct quickly, the air duct is under negative pressure. At the same time, the heat of the high-temperature material in the receiving box is transferred to the heat dissipation fins on the outside. The heat absorbed by the heat dissipation fins causes the surrounding air to heat up and form hot air. Under the action of negative pressure in the air duct, this hot air is drawn into the air duct and mixed with the rapidly flowing cold air in the air duct. They are then drawn upward together. Finally, the mixed gas carrying heat is discharged from the device through the heat dissipation cover. The horn cover is shaped to expand outward. Under the action of negative pressure in the air duct, it can gather and guide the hot air in a larger range around the air inlet to the air inlet, further expanding the range of hot air collection and facilitating the discharge of heat from the heat dissipation fins.

[0014] (ii) The device is equipped with a lifting plate that conveys the material upward along the side wall of the receiving box. The top of the lifting plate is tilted downward so that the material can fall smoothly after being conveyed to a certain height, increasing the contact area between the material and the air, making the cooling more uniform. At the same time, the suction fan rotates with the shaft inside the heat dissipation shroud, generating an upward suction force. This suction force not only draws the air in the air guide pipe upward to assist its discharge, but also allows the hot air in the receiving box to be discharged outside the device through the heat dissipation shroud.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-5This utility model provides a technical solution: a cooling device for bio-organic fertilizer production, including a protective shell 1, a feeding hopper 2 fixedly connected to the outer side of the protective shell 1, a telescopic cylinder 4 fixedly connected to the bottom of the feeding hopper 2, a baffle 5 fixedly connected to the bottom end of the telescopic cylinder 4, and a discharge hopper 3 slidably connected to the outer wall of the baffle 5. It also includes: a material receiving box 6 fixedly connected to the inner side of the protective shell 1, heat dissipation fins 7 fixedly connected to the outer side of the material receiving box 6, an air guide pipe 12 fixedly connected to the inner wall of the heat dissipation fins 7, and an air guide pipe 12 fixedly connected to the bottom of the material receiving box 6. The bottom of the air guide shell 8 is fixedly connected to a dust cover 9, and the bottom of the dust cover 9 is fixedly connected to a drive motor 10. The output end of the drive motor 10 is fixedly connected to a rotating component 11, and the top of the dust cover 9 is fixedly connected to a heat dissipation cover 13. The outer wall of the discharge hopper 3 is fixedly connected to the side wall of the protective shell 1. The heat dissipation fins 7 are linearly arranged along the central axis of the receiving box 6. Both the feed hopper 2 and the discharge hopper 3 extend to the inner side of the receiving box 6. The air guide pipe 12 is arranged in a ring along the central axis of the heat dissipation fins 7, and the bottom end of the air guide pipe 12 is connected to the air guide shell 8. The top is fixedly connected. After the drive motor 10 starts, its output end drives the rotating shaft 111 of the rotating component 11 to rotate. The centrifugal fan 112 at the bottom of the rotating shaft 111 rotates with the rotating shaft 111 inside the air guide shell 8, drawing in outside cold air through the dust cover 9 into the air guide shell 8. Under the action of centrifugal force, the cold air enters the air guide pipe 12 through the air guide shell 8. When the airflow passes through the air guide pipe 12 quickly, the air guide pipe 12 is in a negative pressure state. At the same time, the heat of the high-temperature material in the material receiving box 6 is transferred to the heat dissipation fins 7 on the outside. The heat dissipation fins 7 absorb the heat. The surrounding air is heated to form hot air. This hot air is drawn into the air duct 12 under the action of negative pressure. After mixing with the rapidly flowing cold air in the air duct 12, they are drawn upward together. Finally, the mixed gas carrying heat is discharged from the device through the heat dissipation cover 13. The horn cover 15 is shaped to expand outward. Under the action of negative pressure in the air duct 12, it can gather and guide the hot air in a larger range around the air inlet 14 to the air inlet 14, further expanding the range of hot air collection and facilitating the discharge of heat from the heat dissipation fins 7.

[0023] The rotating component 11 includes a rotating shaft 111, a centrifugal fan 112 fixedly connected to the bottom of the rotating shaft 111, a feeding plate 113 fixedly connected to the outer wall of the rotating shaft 111, a lifting plate 114 fixedly connected to the top of the feeding plate 113, and a suction fan 115 fixedly connected to the top of the rotating shaft 111. The outer wall of the rotating shaft 111 is rotatably connected to the center of the material receiving box 6, and the bottom end of the rotating shaft 111 is fixedly connected to the output end of the drive motor 10. The centrifugal fan 112 is located inside the air guide shell 8, the suction fan 115 is located inside the heat sink 13, and the top end of the rotating shaft 111 is rotatably connected to the center of the heat sink 13. A horn cover 15 is fixedly connected to the outer wall of the air guide pipe 12, and the horn covers 15 are linearly arranged along the central axis of the air guide pipe 12. An air inlet 14 is provided in the middle, and the top end of the air guide pipe 12 is fixedly connected to the bottom of the heat sink 13. When the rotating shaft 111 rotates, the feeding plate 113 rotates with it and sends the material at the bottom of the material receiving box 6 to the bottom of the lifting plate 114. The lifting plate 114 conveys the material upward along the side wall of the material receiving box 6, and the top of the lifting plate 114 is inclined downward so that the material can fall smoothly after being conveyed to a certain height, increasing the contact area between the material and the air, and making the cooling more uniform. During this process, the suction fan 115 at the top of the rotating shaft 111 rotates with the rotating shaft 111 inside the heat sink 13, generating an upward suction force. This suction force not only draws the air in the air guide pipe 12 upward to assist its discharge, but also allows the hot air in the material receiving box 6 to be discharged outside the device through the heat sink 13. When cold air flows in the air duct 12, it exchanges heat with the material receiving box 6 and the heat dissipation fins 7, absorbs the heat of the material and becomes hot air, and finally is discharged through the heat dissipation cover 13 together with the hot air in the material receiving box 6.

[0024] Working principle: When the device is started, the bio-organic fertilizer to be cooled enters the receiving box 6 from the feed hopper 2 outside the protective shell 1;

[0025] After the drive motor 10 starts, its output end drives the rotating shaft 111 of the rotating component 11 to rotate. The centrifugal fan 112 at the bottom of the rotating shaft 111 rotates with the rotating shaft 111 inside the air guide shell 8, drawing in outside cold air through the dust cover 9 into the air guide shell 8. Under the action of centrifugal force, the cold air enters the air guide pipe 12 through the air guide shell 8. When the airflow passes through the air guide pipe 12 quickly, the air guide pipe 12 is in a negative pressure state. At the same time, the heat of the high-temperature material in the material receiving box 6 is transferred to the heat dissipation fins 7 on the outside. The heat absorbed by the heat dissipation fins 7 makes the surrounding area... The air heats up to form hot air, which is drawn into the air duct 12 under the action of negative pressure. After mixing with the rapidly flowing cold air in the air duct 12, the hot air is drawn upward together. Finally, the mixed gas carrying heat is discharged from the device through the heat dissipation cover 13. The horn cover 15 is shaped to expand outward. Under the action of negative pressure in the air duct 12, it can gather and guide the hot air in a larger range around the air inlet 14 to the air inlet 14, further expanding the range of hot air collection and facilitating the discharge of heat from the heat dissipation fins 7.

[0026] At the same time, when the rotating shaft 111 rotates, the feeding plate 113 rotates with it and sends the material at the bottom of the receiving box 6 to the bottom of the lifting plate 114. The lifting plate 114 conveys the material upward along the side wall of the receiving box 6, and the top of the lifting plate 114 tilts downward so that the material can fall smoothly after being conveyed to a certain height, increasing the contact area between the material and the air, and making the cooling more uniform.

[0027] During this process, the suction fan 115 at the top of the rotating shaft 111 rotates with the rotating shaft 111 inside the heat sink 13, generating an upward suction force. This suction force not only draws the air in the air guide pipe 12 upward to assist its discharge, but also allows the hot air in the material receiving box 6 to be discharged outside the device through the heat sink 13. When the cold air flows in the air guide pipe 12, it exchanges heat with the material receiving box 6 and the heat sink fins 7, absorbing the heat of the material and becoming hot air, which is finally discharged through the heat sink 13 together with the hot air in the material receiving box 6.

[0028] When the telescopic cylinder 4 retracts, the baffle 5 moves upward, opening the discharge channel in the discharge hopper 3. Under the centrifugal force generated by the rotation of the feeding plate 113, the material in the receiving box 6 can be discharged through the discharge hopper 3.
