Abstract
Description
Technical Field
[0001] This application relates to the field of feed cooling technology, and more specifically, to a feed cooling device. Background Technology
[0002] In today's feed processing industry, after feed pelleting, the feed is often at a high temperature and needs to be cooled. Air cooling is a common method for feed cooling, which relies on a fan to introduce cool outside air and exchange heat with the hot feed to achieve cooling.
[0003] However, in common cooling box designs, the feed lacks an effective circulation mechanism within the box. Most cooling boxes rely solely on the natural fall of the feed or simple mechanical stirring, making it difficult to achieve sufficient circulation of the feed throughout the cooling space. This results in uneven distribution of the feed within the cooling box, with feed accumulating in some areas for extended periods and failing to fully contact the cold air, leading to insufficient cooling.

[0029] like Figure 1 and Figure 2As shown, this application provides a feed cooling device, including a cooling box 1 with a feed hopper 11 and an exhaust port 12 at the top and a discharge port 13 at the bottom. A discharge hopper 2 is fixed inside the cooling box 1, a discharge assembly 3 is provided at the bottom of the discharge hopper 2, and a feed cylinder 4 is fixed at the top of the discharge hopper 2. An opening 41 is provided on the lower side of the feed cylinder 4. A spiral lifting assembly 5 is rotatably arranged inside the feed cylinder 4. A drive motor 6 is provided at the top of the cooling box 1 to drive the spiral lifting assembly 5 to rotate. A guide assembly 7 is provided between the outer wall of the feed cylinder 4 and the inner wall of the cooling box 1. A cold air conveying assembly 8 is provided on the cooling box 1 to input cold air into the cooling box 1. In use, high-temperature feed enters the cooling box 1 through the feed hopper 11 at the top of the cooling box 1, falls from the guide assembly 7 onto the discharge hopper 2, and enters the bottom of the feed cylinder 4 through the opening 41. The drive motor 6 drives the spiral lifting assembly 5 inside the feed cylinder 4 to rotate, thus discharging the feed into the cooling box 1. The feed at the bottom of cylinder 4 is lifted upwards. When the feed is lifted to a certain height, it is thrown out from the top of cylinder 4 and falls again along the guide assembly 7. At this time, the cold air conveying assembly 8 inputs cold air into the cooling box 1. The cold air comes into full contact with the dispersed high-temperature feed, exchanges heat, and removes the heat from the feed to cool it. During the cooling process, the hot air that has absorbed the heat of the feed is discharged through the exhaust port 12 at the top of the cooling box 1. The fully cooled feed is finally discharged from the discharge port 13 at the bottom of the cooling box 1 through the discharge assembly 3 at the bottom of the discharge hopper 2. Compared with the prior art, this application lifts the feed at the bottom of the cooling box 1 and throws it out from the top of cylinder 4 by spiral lifting assembly 5. Combined with the guide assembly 7 and the cold air conveying assembly 8, the feed is fully circulated and evenly dispersed in the cooling box 1, avoiding feed accumulation and ensuring that the feed comes into full contact with the cold air, thereby improving the feed cooling effect.
[0030] like Figure 2 and Figure 3 As shown, the spiral conveying assembly 5 includes a rotating shaft 51 and spiral blades 52. The lower end of the rotating shaft 51 is rotatably connected to the discharge hopper 2, and the upper end of the rotating shaft 51 is rotatably connected to the cooling box 1. The upper end of the rotating shaft 51 extends to the outside of the cooling box 1 and is connected to the output shaft of the drive motor 6. The spiral blades 52 are fixed on the rotating shaft 51. The drive motor 6 drives the rotating shaft 51 to drive the spiral blades 52 to rotate, thereby lifting the feed.
[0031] like Figure 2As shown, the feeding assembly 7 includes multiple first feeding covers 71 and multiple second feeding covers 72. The multiple first feeding covers 71 are uniformly fixed on the outer wall of the feeding cylinder 4, and the multiple second feeding covers 72 are uniformly fixed on the outer wall of the feeding cylinder 4. The first feeding covers 71 are inclined downward toward the outer wall of the feeding cylinder 4, and the second feeding covers 72 are inclined downward toward the inner wall of the cooling box 1. The first feeding covers 71 and the second feeding covers 72 are staggered vertically. The lifted feed is thrown out from the top of the feeding cylinder 4 and slides down along the first feeding covers 71 and the second feeding covers 72. In the cooling box 1, the feed gradually diffuses from near the feeding cylinder 4 to the inner wall of the cooling box 1 through the second feeding covers 72, and then gradually gathers to the outer wall of the feeding cylinder 4 through the first feeding covers 71. Due to the staggered arrangement of the first feeding covers 71 and the second feeding covers 72, the feed is fully and evenly dispersed in the repetitive diffusion and gathering. The contact area between the evenly dispersed feed and the cold air is greatly increased, improving the heat exchange efficiency.
[0032] like Figure 2 As shown, the top of both the first guide cover 71 and the second guide cover 72 are uniformly fixed with multiple protrusions 9. The protrusions 9 allow the feed particles to be dispersed between the protrusions 9, which promotes the feed to be fully dispersed on the top of the guide cover, so that the feed can be more evenly contacted with the cold air during the subsequent cooling process, thereby further improving the cooling effect of the feed.
[0033] like Figure 1 and Figure 2 As shown, the cold air delivery assembly 8 includes a cold air delivery pipe 81, multiple annular cold air boxes 82, and multiple cold air connecting pipes 83. The multiple annular cold air boxes 82 are fixed to the outside of the cooling box 1 from top to bottom. Multiple cold air through holes 821 are evenly arranged on the side of the annular cold air box 82 closest to the cooling box 1, extending into the cooling box 1. Each annular cold air box 82 corresponds one-to-one with a first guide shroud 71, and is located below the first guide shroud 71. The multiple cold air connecting pipes 83 connect two adjacent annular cold air boxes 82. The cold air delivery pipe 81 connects to one of the annular cold air boxes... The cold air is connected to the cold air supply pipe 81 and connected to a cold air input source. The cold air is transported to one of the annular cold air boxes 82 through the cold air supply pipe 81. The cold air entering the annular cold air box 82 circulates between adjacent annular cold air boxes 82 through the cold air connecting pipe 83, so that each annular cold air box 82 is filled with cold air. Then, it enters the interior of the cooling box 1 through the cold air through hole 821. The feed that slides down from the second guide cover 72 meets the cold air entering from the annular cold air box 82. The cold air and the hot feed have a full heat exchange, which takes away the heat in the feed and cools the feed.
[0034] like Figure 1 and Figure 2As shown, an exhaust fan 10 is installed at the exhaust port 12. During the feed cooling process, hot air continuously accumulates in the cooling box 1. If it is not discharged in time, a hot air layer will form in the box, which will hinder the further heat exchange between the cold air and the feed and reduce the cooling efficiency. The exhaust fan 10 can quickly extract this part of the hot air to ensure that there is always enough space in the cooling box 1 for the cold air to enter and maintain the efficient cooling process.
[0035] like Figure 2 and Figure 3 As shown, the discharge assembly 3 includes a protective box 31, a discharge motor 32, and a baffle 33. The discharge port 21 of the discharge hopper 2 is located on the side. The protective box 31 is fixed to the bottom of the discharge hopper 2. The discharge motor 32 is fixed inside the protective box 31. The output shaft of the discharge motor 32 extends to the bottom of the protective box 31 and is connected to the baffle 33. The baffle 33 bends upward and movably fits against the outer wall of the protective box 31 and the bottom of the discharge hopper 2. The baffle 33 is adapted to the discharge port 21. When it is necessary to discharge the cooled feed, the discharge motor 32 drives the baffle 33 to rotate and gradually removes the obstruction of the discharge port 21 on the side of the discharge hopper 2. The cooled feed falls from the discharge port 21 by its own gravity and is finally discharged from the discharge port 13 of the cooling box 1. When it is necessary to stop discharging, the discharge motor 32 drives the baffle 33 to move back to the position adapted to the discharge port 21, closes the discharge port 21, and prevents the feed from continuing to flow out.
[0036] like Figure 2 and Figure 3 As shown, there are two discharge ports 21, which are symmetrically arranged. The arrangement of two discharge ports 21 can effectively improve the discharge efficiency.
[0037] like Figure 2 and Figure 3 As shown, the bottom of the discharge hopper 2 is provided with an annular limiting groove 22. The side of the baffle 33 is located in the annular limiting groove 22 and is slidably connected with the annular limiting groove 22. The annular limiting groove 22 supports the baffle 33 when it rotates, thereby enhancing the stability of the baffle 33 rotation.
[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
