A cooling device for organic fertilizer production

Abstract

This utility model discloses a cooling device for organic fertilizer production, including a cooling chamber, a feeding cylinder, and a discharging cylinder. A fixed frame is fixedly installed inside the cooling chamber, and a cooling mechanism for cooling the fertilizer is arranged inside the cooling chamber. A feeding mechanism for conveying fertilizer is arranged above the cooling chamber, and the discharge position of the feeding mechanism corresponds to that of the feeding cylinder. A dispersing mechanism is arranged on the feeding mechanism to ensure that the fertilizer is evenly cooled by the cooling mechanism. The cooling mechanism of this utility model is installed inside the cooling chamber, and the subsequent feeding mechanism can evenly convey the fertilizer to be cooled into the inside of the feeding cylinder. This allows the fertilizer to be quickly cooled by the cooling mechanism. The dispersing mechanism, located as the fertilizer falls, evenly spreads the falling fertilizer, ensuring that the fertilizer passes evenly through the inside of the cooling mechanism and preventing waste material from always passing through a fixed position, which would reduce cooling efficiency.

Description

Technical Field

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

[0002] Organic fertilizer refers to fertilizer mainly derived from plants or animals, formed through the accumulation, fermentation, and decomposition of biological matter, plant and animal waste, and plant residues. It not only contains abundant organic matter but also various essential nutrients for crop growth, such as nitrogen, phosphorus, potassium, and trace elements. Using organic fertilizer helps improve soil structure, enhances soil water and fertilizer retention capacity, and promotes soil microbial activity, thus playing a vital role in environmental protection and sustainable agricultural development.

[0003] In the production of organic fertilizer, to facilitate transportation and storage and prevent nutrient loss, the organic fertilizer needs to be processed into granular fertilizer through specific processes. However, directly packaging or storing granular organic fertilizer may not only lead to a decline in product quality but also pose safety hazards such as spontaneous combustion due to internal heat accumulation. Therefore, after the organic fertilizer granules are manufactured, their temperature needs to be reduced by a cooling device to ensure product quality and safety. Existing organic fertilizer cooling devices use water-cooled plates for cooling during production. However, this cooling method cannot ensure that the fertilizer is evenly cooled by the water-cooled plates, resulting in a decrease in cooling efficiency. To address this, we propose a cooling device for organic fertilizer production. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for organic fertilizer production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for organic fertilizer production, comprising a cooling chamber, a feed cylinder fixedly connected to the top of the cooling chamber, a discharge cylinder fixedly connected to the bottom of the cooling chamber, a fixed frame fixedly installed inside the cooling chamber, a cooling mechanism for cooling fertilizer inside the cooling chamber, a feeding mechanism for conveying fertilizer above the cooling chamber, the discharge position of the feeding mechanism corresponding to the feed cylinder, and a dispersing mechanism for uniformly cooling fertilizer by passing the fertilizer through the cooling mechanism on the feeding mechanism and at the position corresponding to the feed cylinder.

[0006] Furthermore, the cooling mechanism includes a water-cooled plate, a fixing block, a mounting plate, a mounting bracket, an inlet pipe, an outlet pipe, and a connecting pipe. The water-cooled plate is configured in multiple groups, and the interior of the water-cooled plate is a hollow tube. The multiple groups of water-cooled plates are fixedly connected by the fixing block. The top of the water-cooled plate is fixedly connected to the mounting plate, which overlaps the fixing bracket. The mounting plate has a locking groove. The two sides of the cooling chamber are fixedly connected to the inlet pipe and the outlet pipe by multiple groups of mounting brackets. The two sides of the water-cooled plate are connected to the inlet pipe and the outlet pipe by the connecting pipe.

[0007] Furthermore, the feeding mechanism includes a feeding pipe, conveying blades, a first drive motor, a feeding bin, and a discharging pipe. The first drive motor is fixedly installed on one side of the feeding pipe, and the output end of the first drive motor is fixedly connected to the conveying blades. The feeding bin is provided through the top of the feeding pipe, and the discharging pipe is fixedly connected to the bottom of the feeding pipe at the position corresponding to the feeding cylinder.

[0008] Furthermore, the bulk material mechanism includes an installation block, a second drive motor, a rotating shaft, a bulk material tray, a spreading plate, and a discharge chute. The installation block is fixedly installed on the top of the feeding pipe, and the second drive motor is fixedly installed on the top of the installation block. The output end of the second drive motor is fixedly connected to the rotating shaft. The bulk material tray is fixedly connected to the bottom of the rotating shaft and inside the feeding cylinder. Multiple spreading plates are fixedly installed on the top of the bulk material tray, and multiple discharge chutes are formed through the bulk material tray.

[0009] Furthermore, a guide plate is fixedly connected to the top of the water-cooled plate, and the top of the guide plate is arc-shaped.

[0010] Furthermore, the cooling chamber, feed cylinder, discharge cylinder, water-cooled plate, fixing block, mounting plate, connecting pipe, material distribution tray, and spreading plate are all made of stainless steel.

[0011] Compared with the prior art, the present invention has the following advantages: The cooling mechanism of the present invention is installed inside the cooling chamber, and the feeding mechanism thereafter can evenly transport the fertilizer that needs to be cooled into the inside of the feeding cylinder. This allows the fertilizer to be cooled quickly through the cooling mechanism. When the feeding mechanism is conveying the fertilizer down, the dispersing mechanism can evenly spread the falling fertilizer, so that the fertilizer can pass through the inside of the cooling mechanism evenly and there will be no excessive accumulation of waste material when it falls. This allows the cooling mechanism to be used more fully and avoids the situation where waste material always passes through the fixed position of the cooling mechanism, which would lead to a decrease in cooling efficiency.

[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a cooling device for organic fertilizer production, including a cooling chamber 1, a feed cylinder 2 fixedly connected to the top of the cooling chamber 1, a discharge cylinder 3 fixedly connected to the bottom of the cooling chamber 1, a fixed frame 4 fixedly installed inside the cooling chamber 1, a cooling mechanism 5 for cooling fertilizer inside the cooling chamber 1, a feeding mechanism 6 for conveying fertilizer above the cooling chamber 1, the discharge position of the feeding mechanism 6 corresponding to the feed cylinder 2, and a dispersing mechanism 7 for uniformly cooling fertilizer by passing through the cooling mechanism 5 on the feeding mechanism 6 and corresponding to the position of the feed cylinder 2.

[0019] The cooling mechanism 5 is installed inside the cooling chamber 1. The feeding mechanism 6 then evenly conveys the fertilizer that needs to be cooled into the feed cylinder 2, so that the fertilizer can be cooled quickly through the cooling mechanism 5. When the feeding mechanism 6 conveys the fertilizer down, the dispersing mechanism 7 can evenly spread the falling fertilizer, so that the fertilizer can pass through the interior of the cooling mechanism 5 evenly, and there will be no excessive accumulation of waste material when it falls. This allows the cooling mechanism 5 to be used more fully and avoids the waste material always passing through the fixed position of the cooling mechanism 5, which would reduce the cooling efficiency.

[0020] Please see Figure 1 and Figure 3 The cooling mechanism 5 includes a water-cooled plate 8, a fixing block 9, a mounting plate 10, a mounting bracket 12, an inlet pipe 13, an outlet pipe 14, and a connecting pipe 15. The water-cooled plate 8 is configured in multiple groups, and the interior of the water-cooled plate 8 is a hollow tube. The multiple groups of water-cooled plates 8 are fixedly connected by the fixing block 9. The top of the water-cooled plate 8 is fixedly connected to the mounting plate 10, which overlaps the mounting bracket 4. The mounting plate 10 is provided with a locking groove 11. The two sides of the cooling chamber 1 are fixedly connected to the inlet pipe 13 and the outlet pipe 14 by multiple groups of mounting brackets 12. The two sides of the water-cooled plate 8 are connected to the inlet pipe 13 and the outlet pipe 14 by the connecting pipe 15.

[0021] The multiple sets of water-cooled plates 8 are fixedly connected by fixing blocks 9 and installed on the fixing frame 4 by mounting plate 10 and locking groove 11. The liquid inlet pipe 13 is connected to the external water-cooling medium. The water-cooling medium then enters the interior of the water-cooled plate 8 through the connecting pipe 15. When the waste passes between the multiple sets of water-cooled plates 8, the fertilizer can be cooled down by the water-cooled plates 8.

[0022] Please see Figure 1 , Figure 2 and Figure 4 The feeding mechanism 6 includes a feeding pipe 16, a conveying blade 17, a first drive motor 18, a feeding bin 19, and a discharging pipe 20. The first drive motor 18 is fixedly installed on one side of the feeding pipe 16, and the output end of the first drive motor 18 is fixedly connected to the conveying blade 17. The feeding bin 19 is provided through the top of the feeding pipe 16, and the discharging pipe 20 is fixedly connected to the bottom of the feeding pipe 16 at the position corresponding to the feeding cylinder 2.

[0023] In this process, the fertilizer that needs to be cooled is placed into the inside of the feed hopper 19, and then the first drive motor 18 drives the conveying blades 17 to rotate, so that the fertilizer can be discharged into the inside of the feed cylinder 2 through the feed pipe 16 and the discharge pipe 20.

[0024] Please see Figure 1 and Figure 4 The bulk material mechanism 7 includes a mounting block 21, a second drive motor 22, a rotating shaft 23, a bulk material tray 24, a spreading plate 25, and a discharge chute 26. The mounting block 21 is fixedly installed on the top of the feeding pipe 16. The second drive motor 22 is fixedly installed on the top of the mounting block 21. The output end of the second drive motor 22 is fixedly connected to the rotating shaft 23. The bulk material tray 24 is fixedly connected to the bottom of the rotating shaft 23 and located inside the feeding cylinder 2. Multiple spreading plates 25 are fixedly installed on the top of the bulk material tray 24. Multiple discharge chute 26 are opened through the bulk material tray 24.

[0025] When the fertilizer falls, the second drive motor 22 drives the rotating shaft 23 and the distribution plate 24 to rotate, so that the fertilizer falls onto the distribution plate 24. Then, due to the rotation of the distribution plate 24, the fertilizer falls outward due to centrifugal force and the action of the spreading plate 25. Another part of the fertilizer falls through multiple sets of feeding troughs 26, so that the fertilizer can be evenly cooled by multiple sets of water cooling plates 8.

[0026] Please see Figure 1 and Figure 3 A guide plate 27 is fixedly connected to the top of the water-cooled plate 8. The top of the guide plate 27 is arc-shaped, which can prevent fertilizer from overlapping on the top of the water-cooled plate 8.

[0027] Please see Figures 1-4 The cooling chamber 1, feed cylinder 2, discharge cylinder 3, water cooling plate 8, fixing block 9, mounting plate 10, connecting pipe 15, material distribution tray 24 and spreading plate 25 are all made of stainless steel. The multiple sets of components made of stainless steel can prevent fertilizer from corroding and damaging the components.

[0028] In use, the cooling mechanism 5 is first installed inside the cooling chamber 1. Then, the feeding mechanism 6 evenly conveys the fertilizer to be cooled into the feed cylinder 2, allowing the fertilizer to be rapidly cooled by the cooling mechanism 5. During the downward flow of the fertilizer conveyed by the feeding mechanism 6, the dispersing mechanism 7 evenly spreads the falling fertilizer, ensuring it passes evenly through the cooling mechanism 5 and preventing excessive accumulation of waste material. This allows the cooling mechanism 5 to be used more efficiently and avoids a decrease in cooling efficiency caused by waste material constantly passing through a fixed position. Multiple sets of water-cooled plates 8 are fixedly connected by fixing blocks 9 and mounted on the fixing frame 4 via mounting plates 10 and locking slots 11. Finally, the liquid inlet pipe 13 connects to the external water-cooling medium. Subsequently, the cooling medium enters the interior of the water-cooled plate 8 through the connecting pipe 15. When the waste passes between multiple sets of water-cooled plates 8, the fertilizer can be cooled down by the water-cooled plates 8. The fertilizer that needs to be cooled is put into the interior of the feeding hopper 19. Then, the first drive motor 18 drives the conveying blades 17 to rotate, so that the fertilizer can be discharged into the interior of the feeding cylinder 2 through the feeding pipe 16 and the discharge pipe 20. When the fertilizer falls, the second drive motor 22 drives the rotating shaft 23 and the distributing plate 24 to rotate, so that the fertilizer falls onto the distributing plate 24. Then, due to the rotation of the distributing plate 24, the fertilizer can be expanded and fall outward due to centrifugal force and the action of the spreading plate 25. Another part of the fertilizer falls through multiple sets of feeding troughs 26, so that the fertilizer can be evenly cooled down by multiple sets of water-cooled plates 8.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
