Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of feed processing equipment, and more specifically, to a feed cooling device for assisting in turning over feed during feed processing. Background Technology

[0002] In feed processing, feed that has undergone high-temperature pelleting or extrusion needs to be cooled to reduce its moisture and temperature to storage standards. This is a crucial step in ensuring the shelf life and nutritional value of the feed. Currently, commonly used feed cooling devices mostly employ fixed bed layers or single ventilation structures, which generally suffer from poor cooling effects and low efficiency.

[0003] In actual production, high-temperature feed is prone to forming "dead zones" due to uneven packing density during the cooling process, resulting in the outer layer of feed being over-cooled while the inside remains at a high temperature, leading to incomplete cooling. At the same time, the feed in a static state has a limited contact area with cold air, resulting in low heat exchange efficiency. This not only prolongs the cooling cycle but also causes some nutrients to be lost due to continuous high temperatures.

[0004] To address this issue, some manufacturers have compensated by increasing fan power or extending cooling time. However, this not only significantly increases energy consumption but also easily leads to feed pellet breakage, affecting product quality. Therefore, the industry urgently needs new devices that can improve cooling uniformity and efficiency through auxiliary turning structures to achieve the dual goals of energy saving, consumption reduction, and product quality improvement. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a feed cooling device for auxiliary turning in feed processing, which solves the technical problem in the prior art that poor cooling effect leads to increased time cost in the feed production process and affects production efficiency.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a feed cooling device for assisting in turning over feed during feed processing, comprising:

[0007] A cooling box and a rotating cover, wherein the rotating cover is rotatably connected inside the cooling box and is driven to rotate by electricity;

[0008] The infeed and discharge assembly is disposed on both sides outside the cooling box;

[0009] A tilting drying assembly is disposed within the cooling box and the rotating hood;

[0010] The rotating drying assembly includes several turning racks, the rotating cover has diffusion holes on its surface, a docking circular plate is fixedly connected to the outside of the cooling box, the docking circular plate is rotatably fitted inside one end of the rotating cover, and an air inlet pipe is provided on the docking circular plate.

[0011] As a further technical solution, a side air intake shroud is installed on the outside of the cooling box, one end of which is located inside the cooling box, and the side air intake shroud is connected to the air intake pipe.

[0012] As a further technical solution, a dispersion hole is provided at the bottom of the side air intake hood, an air collection hood is provided on the inner surface of one side of the cooling box, an air intake hole is provided at the bottom of the air collection hood, and a suction pipe is provided on the outer side of the air intake hood.

[0013] As a further technical solution, the feeding and discharging assembly includes a feeding hood, which is fixed to one side of the cooling box and is connected to the interior of the cooling box. One end of the feeding hood extends outward, and a pushing auger is installed in the extended portion of the feeding hood.

[0014] As a further technical solution, the top of the feed hood is provided with an inlet, which is located directly above the push auger, and the side of the cooling box is provided with an outlet, which is equipped with a cover that is flipped by electric power.

[0015] As a further technical solution, the material turning frame has an overall L-shaped structure, and the surface of the material turning frame has a hollow structure.

[0016] As a further technical solution, the bottom of the cooling box has a semi-circular structure, and the end face of the material turning frame slides against the inner wall of the cooling box.

[0017] As a further technical solution, a sliding hopper is provided on one side of the cooling box, and the sliding hopper is located below the discharge port.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the turning and drying assembly solves the problem of poor performance of traditional cooling devices through dynamic turning and three-dimensional air supply. The L-shaped turning rack rotates with the rotating hood, continuously lifting the feed and increasing the contact area with cold air; the side air inlet hood and diffuser holes work together to form a multi-dimensional airflow, which, together with the suction pipe, accelerates heat and moisture exchange and avoids local overheating or uneven cooling. This design significantly shortens the cooling time, reduces nutrient loss, and the perforated turning rack reduces feed adhesion, improving cooling uniformity and efficiency.

[0020] 2. In this disclosure, the feeding and discharging components solve the problem of feed conveying blockage through continuous conveying and precise control. The auger smoothly pushes the feed into the cooling box, preventing accumulation; the cover flips to control the opening and closing of the discharge port, and together with the tipping frame, it achieves orderly discharge; the sliding hopper guides the feed for smooth collection. The reasonable layout of the inlet and outlet ensures smooth connection between feeding and discharging, adapts to the continuous production rhythm, reduces manual intervention, and improves overall production efficiency.

[0032] like Figures 1-3 As shown, it illustrates a feed cooling device for assisting in turning over feed in one embodiment of the present disclosure, comprising:

[0033] The cooling box 1 and the rotating cover 2 are rotatably connected inside the cooling box 1 and are driven to rotate by electricity.

[0034] Feeding and discharging components 4 are disposed on both sides outside the cooling box 1;

[0035] A flip-drying assembly 3 is disposed within the cooling box 1 and the rotating cover 2;

[0036] The rotating drying assembly 3 includes several turning racks 3-1. The rotating cover 2 has diffusion holes 3-2 on its surface. A docking circular plate 3-3 is fixedly connected to the outside of the cooling box 1. The docking circular plate 3-3 is rotatably fitted inside one end of the rotating cover 2. An air inlet pipe 3-4 is provided on the docking circular plate 3-3. A side air inlet cover 3-5 is installed on the outside of the cooling box 1. One end of the side air inlet cover 3-5 is located inside the cooling box 1. The side air inlet cover 3-5 is connected to the air inlet pipe 3-4. A dispersion hole 3-6 is provided at the bottom of the side air inlet cover 3-5. A gas collecting cover 3-7 is provided on one side surface of the cooling box 1. An air inlet hole 3-8 is provided at the bottom of the gas collecting cover 3-7. A suction pipe 3-9 is provided on the outside of the gas inlet cover.

[0037] In some examples, a rotating drying assembly 3 is designed to achieve continuous turning and cooling of the feed. This assembly includes a rotating hood 2, which is rotatably mounted inside a cooling box 1 via bearings and driven by a motor. Diffuser holes 3-2 are evenly distributed on the surface, allowing airflow into the interior. A connecting circular plate 3-3 on the outer side of the cooling box 1 is fixed by welding, with a raised ring on its edge rotating and fitting into an opening at one end of the rotating hood 2 to ensure a tight seal during rotation. An air inlet pipe 3-4 at the center of the connecting circular plate 3-3 is connected to an external air source. A side air inlet hood 3-5 on the outer side of the cooling box 1 is fixed by a bracket, with one end extending into the interior of the cooling box 1 and connected to the air inlet pipe 3-4 via a flexible hose. Dispersion holes 3-6 at the bottom are arranged in an array to evenly blow airflow onto the feed. A gas collecting hood 3-7 on one side surface of the cooling box 1 is fixed by clips, with the bottom air inlet 3-8 facing the rotating hood 2. An outer suction pipe 3-9 connects the gas collecting hood 3-7 to a negative pressure device. A turning rack 3-1 inside the rotating hood 2 is welded to the hood body.

[0038] During operation, the rotating hood 2 drives the turning frame 3-1 to rotate, continuously turning and lifting the feed to fully expose it to the airflow. Simultaneously, external cold air enters the side air intake hood 3-5 through the air intake pipe 3-4 and is blown onto the feed inside the rotating hood 2 through the diffuser holes 3-2. The air intake holes 3-8 on the surface of the rotating hood 2 also introduce some airflow. The hot airflow carrying moisture is drawn into the air collection hood 3-7 through the air intake holes 3-8 and discharged through the suction pipe 3-9, forming an airflow circulation. The spiral structure of the turning frame 3-1 propels the feed while turning, the rotating seal of the connecting circular plate 3-3 ensures stable airflow delivery, and the dispersion holes 3-6 ensure even airflow distribution. This component combines mechanical turning with airflow drying to achieve continuous turning and efficient drying of the feed, improving cooling and drying efficiency.

[0039] like Figures 1-3 As shown in the figure, the feeding and discharging assembly 4 in this embodiment includes a feeding hood 4-1, which is fixed to one side of the cooling box 1 and is connected to the interior of the cooling box 1. One end of the feeding hood 4-1 extends outward, and a pusher auger 4-2 is installed in the extended part of the feeding hood 4-1. An inlet 4-3 is opened at the top of the feeding hood 4-1, which is located directly above the pusher auger 4-2. An outlet 4-4 is opened on one side of the cooling box 1, and a cover 4-5 that is electrically driven to flip is provided in the outlet 4-4.

[0040] In some examples, to achieve sufficient feeding and orderly discharge of feed, a feeding / discharging assembly 4 is designed. This assembly includes a feeding hood 4-1 welded and fixed to one side of the cooling tank 1, communicating with the interior of the cooling tank 1. The extended pusher auger 4-2 is rotatably connected via bearings and driven to rotate by a motor. The blades are in contact with the inner wall of the feeding hood 4-1. The top inlet 4-3 is located directly above the pusher auger 4-2 for easy feed feeding. The outlet 4-4 on one side of the cooling tank 1 communicates with the interior. A cover 4-5 is rotatably connected to the edge of the outlet 4-4 via a pin and is driven to flip by a motor, enabling the opening and closing of the outlet 4-4.

[0041] During operation, feed is poured in through inlet 4-3 and falls onto the auger 4-2. The rotating auger pushes the feed into the cooling tank 1 smoothly and continuously, preventing feed accumulation and blockage. After the feed has cooled and dried, the motor drives the cover 4-5 to flip and open the outlet 4-4. The feed is then discharged from the outlet 4-4 by the pusher 3-1. After discharge, the cover 4-5 flips back to close the outlet 4-4, ensuring the cooling tank 1 is airtight. The continuous pushing of the auger 4-2 ensures sufficient feeding, the design of the inlet 4-3 prevents feed spillage, and the flipping control of the cover 4-5 enables precise opening and closing of the outlet 4-4. This component, through mechanical pushing and flipping control, achieves efficient feed feeding and orderly discharge, ensuring continuous and stable operation of the device.

[0042] For example, such as Figure 3 As shown, the flipping rack 3-1 has an overall L-shaped structure, and the surface of the flipping rack 3-1 has a hollow structure.

[0043] In some examples, the L-shaped feed turner 3-1 enhances the turning effect on the feed. The vertical section lifts the feed at the bottom upwards, while the horizontal section pushes the feed forward. The perforated surface reduces the contact area with the feed, reducing adhesion, while facilitating airflow to ensure full contact between the feed and the cooling airflow, improving cooling and drying efficiency. It also reduces the resistance when the feed turner 3-1 rotates, making the rotation smoother.

[0044] For example, such as Figure 3 As shown, the bottom of the cooling box 1 has a semi-circular structure, and the end face of the turning frame 3-1 slides against the inner wall of the cooling box 1.

[0045] In some examples, the semi-circular structure at the bottom of the cooling tank 1 slides against the end face of the tipping frame 3-1, preventing feed from accumulating at the bottom. The semi-circular design allows the feed to naturally gather towards the center as the tipping frame 3-1 rotates. The sliding of the tipping frame 3-1 against the inner wall scrapes away residual feed, ensuring that all feed is turned over and processed. At the same time, it enhances the structural stability of the cooling tank 1 and makes the airflow more uniform inside.

[0046] For example, such as Figure 1As shown, a sliding hopper 5 is provided on one side of the cooling box 1, and the sliding hopper 5 is located below the discharge port 4-4.

[0047] In some examples, the hopper 5 below the discharge port 4-4 is inclined to guide the discharged feed smoothly down. After being discharged from the discharge port 4-4, the feed falls onto the hopper 5 and slides along the inclined surface to the collection device, preventing feed from scattering and reducing waste and cleanup work. The hopper 5 makes the discharge process more orderly, adapts to different collection methods, and improves the practicality of the device.

[0048] In actual use: High-temperature feed is poured into the feed hood 4-1 through the inlet 4-3, and the auger 4-2 pushes it smoothly into the cooling box 1. The rotating hood 2 drives the L-shaped turning frame 3-1 to rotate, continuously turning and lifting the feed to prevent it from piling up and forming cooling dead zones. The air inlet pipe 3-4 sends cold air into the side air inlet hood 3-5, which is then blown evenly onto the feed through the dispersion hole 3-6 and the diffusion hole 3-2. The hot and humid airflow is drawn in by the air collection hood 3-7 through the air inlet hole 3-8 and discharged through the suction pipe 3-9 to form a circulation. After cooling is completed, the cover 4-5 flips open the outlet 4-4, and the turning frame 3-1 pushes the feed out through the sliding hopper 5. The entire process achieves continuous turning and efficient heat exchange without the need for mid-process shutdown.
