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.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] In this technical solution, a feed additive pellet cooling device includes a support base 1 and a cooling drum 2. Support seats 11 are vertically installed on both sides of the top of the support base 1, and turntables 12 are installed on the opposite sidewalls of the two support seats 11. A fixed plate a7 is installed on the sidewall of one turntable 12, and a fixed plate b6 is installed on the sidewall of the other turntable 11. The cooling drum 2 is assembled between the fixed plate a7 and the fixed plate b6. Support plates 17 are installed on the inner walls of both the upper and lower sides of the cooling drum 2, and support frames 18 are installed on the sidewalls of the support plates 17. Cooling fins 19 are provided at the ends of the support frames 18. Ventilation holes 3 are evenly spaced on the outer surface of the cooling drum 2, and the inner diameter of the ventilation holes 3 is smaller than the outer diameter of the feed additive. An air exchange port 4 is opened on the outer wall of the cooling drum 2, and a fan assembly 5 is installed inside the air exchange port 4.

[0022] The support base 1, as the basic support structure of the equipment, must possess sufficient strength and stability to support the weight of the entire equipment and its internal materials. It can be welded from high-strength steel, and its bottom can be fitted with shock-absorbing rubber pads to reduce vibration and noise transmission during equipment operation. The support base 11 and the support base 1 are fixedly connected by bolts to ensure a secure installation. The turntable 12 is mounted on the opposite side wall of the support base 11 to support and rotate the cooling drum 2. The turntable 12 can be made of cast iron with a precision-machined surface to ensure accurate connection with the cooling drum 2 and smooth rotation.

[0023] The dimensions of the support base 1 can be determined according to the overall size of the equipment and the load-bearing requirements. For example, the length × width × height is 2000mm × 1500mm × 200mm; the support base 11 has a height of 1500mm and a cross-sectional dimension of 200mm × 200mm; the turntable 12 has a diameter of 500mm and a thickness of 30mm.

[0024] Fixed disks a7 and b6 serve to fix and support the cooling roller 2, and can be tightly connected to the turntable 12 by bolts. The cooling roller 2 can be assembled with fixed disks a7 and b6 by shaft hole fit. Shaft heads are provided at both ends of the cooling roller 2, which are interference fit with the shaft holes on the fixed disks, and torque is transmitted by key connection to ensure that the cooling roller 2 is stable and reliable during rotation.

[0025] Fixed disks a7 and b6 have a diameter of 450mm and a thickness of 25mm; cooling roller 2 has a length of 1200mm, an outer diameter of 800mm, a wall thickness of 10mm, a shaft head diameter of 80mm, and a length of 100mm.

[0026] A sealing structure is provided between the cooling roller 2 and the fixed plate to prevent leakage of feed additive particles; at the same time, a fine-tuning mechanism for the fixed plate can be provided to facilitate adjustment of the coaxiality of the cooling roller 2 during installation.

[0027] The support plate 17, used to support and fix the support frame 18 and cooling fins 19, can be made of 8mm thick steel plate and fixed to the inner wall of the cooling drum 2 by welding. The support frame 18 can be made of angle steel, with one end welded to the support plate 17 and the other end used to install the cooling fins 19. The cooling fins 19 can be made of aluminum heat sinks, which have good thermal conductivity and can effectively absorb and dissipate heat from the particles. The cooling fins 19 can be fixed to the support frame 18 by bolts or rivets, and an appropriate gap should be maintained between the cooling fins 19 to ensure smooth airflow.

[0028] The support plate 17 is 1000mm long and 100mm wide; the support frame 18 is made of ∠50×50×5 angle steel and is 200mm long; the cooling fins 19 are 150mm×100mm×2mm in size and the spacing between adjacent cooling fins 19 is 20mm.

[0029] Ventilation holes 3 are evenly distributed on the outer wall of the cooling drum 2, ensuring free airflow inside and outside the drum for effective cooling of the particles. The ventilation holes 3 can be circular, and their inner diameter should be determined based on the minimum size of the feed additive particles to ensure that particles do not leak out of the ventilation holes 3. The air vent 4 is used to install the fan assembly 5, and its size should be compatible with the fan assembly 5. A flange can be provided on the edge of the air vent 4, which is then fixedly connected to the housing of the fan assembly 5 with bolts.

[0030] Ventilation hole 3 has a diameter of 5mm, and the distance between adjacent ventilation holes 3 is 50mm; air exchange port 4 has a size of 300mm×300mm;

[0031] A filter screen is installed at the ventilation hole 3 to prevent debris from entering the cooling drum 2; at the same time, a sealing device can be added to the air exchange port 4 to prevent heat loss when the fan assembly 5 is not working.

[0032] In some technical solutions, a feed pipe 8 is installed at the upper end of one side support 11, and the feed pipe 8 is connected to the fixed plate b6. A controller 10 is installed on the side wall of the other side support 11.

[0033] The feed pipe 8 is used to convey feed additive granules into the cooling drum 2. It can be made of stainless steel, which is corrosion-resistant and does not easily leave residue. The feed pipe 8 can be welded to the fixed plate b6 to ensure a sealed connection. The controller 10 can be a PLC controller used to control the equipment's operating parameters, such as the speed of the drive motor and the wind speed of the fan assembly 5. The controller 10 is installed on the side wall of the support base 11 and should be equipped with a protective housing to prevent dust and moisture from entering and affecting its normal operation.

[0034] The feed pipe 8 has an inner diameter of 100mm and a length of 500mm; the controller 10 has an IP54 protection rating.

[0035] A spiral conveyor can be installed inside the feed pipe 8 to ensure uniform and stable feeding of particles; at the same time, a communication interface between the controller 10 and the host computer can be added to realize remote monitoring and control.

[0036] In some technical solutions, the top of the feed pipe 8 is equipped with a feed hopper 9.

[0037] The feed hopper 9 is used to facilitate the manual or mechanical pouring of feed additive granules into the feed pipe 8. Its shape can be a funnel, wider at the top and narrower at the bottom, and its material is the same as that of the feed pipe 8. The feed hopper 9 and the feed pipe 8 can be connected via a flange for easy disassembly and cleaning.

[0038] The feed hopper 9 has an upper diameter of 500mm, a lower diameter of 120mm, and a height of 300mm;

[0039] Anti-clogging devices, such as vibrating plates or stirring paddles, can be installed inside the feed hopper 9 to prevent particles from accumulating and clogging; at the same time, a viewing window can be added to the feed hopper 9 to facilitate observation of the feeding situation.

[0040] In some technical solutions, the fan assembly 5 includes an internal fan frame 47 assembled inside the air exchange port 4. A central seat 41 is assembled in the middle section of the internal part of the fan frame 47. Blades 42 are assembled around the central seat 41. A reinforcing rib 44 is installed at the end edge of the blade 42.

[0041] The fan bracket 47, serving as the support frame for the fan assembly 5, can be made of aluminum alloy, featuring light weight and high strength. The fan bracket 47 is bolted to the air vent 4, and its internal structure must ensure the installation accuracy and stability of the center seat 41 and the blades 42. The center seat 41, used to fix the blades 42, can be made of cast aluminum and connected to the fan motor shaft via a key or bolt connection. The blades 42 can be made of plastic or aluminum alloy, with their shape and angle optimized to improve airflow efficiency. Reinforcing ribs 44 enhance the structural strength of the blades 42 and can be fixedly connected to the blades 42 via welding or injection molding.

[0042] The fan bracket 47 measures 320mm × 320mm × 20mm; the center seat 41 has a diameter of 80mm and a thickness of 30mm; the blade 42 has a length of 150mm, a width of 50mm, and a thickness of 3mm; the reinforcing rib 44 has a width of 8mm and a thickness of 2mm.

[0043] Adding a shock-absorbing device to the fan bracket 47 reduces vibration and noise during fan operation; at the same time, an angle adjustment mechanism for the blade 42 can be set to facilitate adjustment of the air delivery direction according to actual needs.

[0044] In some technical solutions, the reinforcing rib 44 is formed from one end 43 to the other end 45, forming a raised reinforcing rib 44 from low to high, and one end 43 of the reinforcing rib 44 extends beyond the end edge of the blade body 42.

[0045] This design effectively enhances the structural strength of the blade tip 42, preventing deformation or breakage during high-speed rotation. The reinforcing rib 44 can be arc-shaped or trapezoidal, and its height and length should be optimized according to the size of the blade 42 and the stress conditions. The length of the reinforcing rib 44 extending beyond the edge of the blade tip 42 should be moderate; too long may increase air resistance, while too short will not achieve the desired reinforcement effect.

[0046] The height difference of the reinforcing rib 44 from one end 43 to the other end 45 is 10mm, and the length exceeding the end edge of the blade body 42 is 15mm.

[0047] The surface of the stiffener 44 is smoothed to reduce air resistance; at the same time, the influence of different shapes of stiffeners 44 on the performance of the blade 42 can be studied to further optimize the design of the stiffener 44.

[0048] In some technical solutions, the beginning of the blade 42 is provided with a chamfer 46, and the blade 42 is inclined.

[0049] The chamfer 46 at the beginning of blade 42 reduces air resistance when it enters, improving the fan's intake efficiency. The inclined design of blade 42 allows for axial and radial airflow, enhancing ventilation. The inclination angle of blade 42 should be precisely calculated and adjusted according to the fan's design airflow and pressure requirements.

[0050] The chamfer angle of the blade body 42 starting point 46 is 45°, and the tilt angle of the blade body 42 is 30°;

[0051] Wind tunnel tests were conducted on blades 42 with different tilt angles and chamfer dimensions to obtain the optimal design parameters for blades 42; at the same time, a drag-reducing coating can be applied to the surface of blades 42 to further reduce air resistance.

[0052] 1. Heat exchange principle

[0053] Conductive heat dissipation: The high-temperature particles are in direct contact with the cooling plate 19, and heat is transferred from the particles to the cooling plate 19 through thermal conduction. The cooling plate 19 is made of aluminum alloy, which has good thermal conductivity (the thermal conductivity of aluminum alloy is about 200W / m·K), and can quickly remove heat.

[0054] Convection cooling: The airflow generated by the fan assembly 5 enters the interior of the cooling drum 2 through the ventilation holes 3, where it undergoes convective heat exchange with the particles and the surface of the cooling fins 19. The inclined blades 42 (30°) create axial and radial airflow, enhancing the heat exchange effect. According to the convective heat transfer formula Q = hAΔT (where Q is the heat transfer capacity, h is the convective heat transfer coefficient, A is the heat transfer area, and ΔT is the temperature difference), the equipment improves cooling efficiency by increasing the heat transfer area (cooling fins 19) and increasing the convective heat transfer coefficient (high-speed airflow).

[0055] Radiative heat dissipation: The high-temperature particles and the surface of the cooling plate 19 also dissipate heat to the surrounding environment through thermal radiation, further assisting the cooling process.

[0056] 2. Mechanical transmission principle

[0057] The power of the drive motor 13 is transmitted to the drive gear 15 through the drive shaft 14. The drive gear 15 meshes with the drive chain 16, driving the fixed disk b6 to rotate, thereby causing the entire cooling drum 2 to rotate. This chain drive method features smooth transmission and high load-bearing capacity, making it suitable for long-term stable operation of the equipment.

[0058] The lubrication device (optional) between the turntable 12 and the support base 11 reduces rotational friction and lowers energy consumption. The fine machining treatment of the turntable 12 surface (surface roughness Ra≤1.6μm) ensures the rotational accuracy of the cooling roller 2.

[0059] 3. Structural Optimization Principles

[0060] Ventilation hole design: Ventilation holes 3 are evenly distributed on the outer wall of cooling drum 2, with a diameter of 5mm and a spacing of 50mm. This design ensures airflow while preventing particle leakage. A filter screen (optional) at the ventilation holes 3 further prevents debris from entering the drum and affecting the cooling effect.

[0061] Fan assembly optimization: The reinforcing rib 44 at the end of the blade 42 (10mm height difference, extending 15mm beyond the blade edge) enhances structural strength and prevents deformation during high-speed rotation. The curved design and smooth surface treatment of the reinforcing rib 44 reduce air resistance. The drag-reducing coating on the surface of the blade 42 (optional) further reduces wind resistance and improves fan efficiency.

[0062] Control System: The controller 10 adopts a PLC control system, which can precisely adjust the speed of the drive motor 13 and the airflow of the fan assembly 5 according to the particle characteristics and cooling requirements. The controller 10 can also realize remote monitoring and control through a host computer communication interface (optional configuration), which improves the intelligence level of the equipment.

[0063] 4. Sealing and Stability Principles

[0064] The sealing structure (optional) between the cooling roller 2 and the fixed disks a7 and b6 prevents particle leakage, ensuring the cleanliness and safety of the equipment. High-temperature resistant rubber sealing rings can be used as the sealing material, with an operating temperature range of -40℃ to 120℃, meeting the equipment's usage requirements.

[0065] The verticality adjustment structure of the support base 11 (optional configuration) ensures the installation level of the turntable 12, guarantees the coaxiality of the cooling roller 2 (coaxiality error ≤0.1mm), and reduces vibration and noise during equipment operation.
