[0027] The following is for reference. Figure 1 and Figure 2 This invention describes a bulk feed drying silo according to an embodiment of the present invention.

[0028] like Figure 1 and Figure 2 As shown, the feed bulk drying bin according to an embodiment of the present invention includes a drying main bin 100, a drum screen 200, and a vibrating screen plate 300.

[0029] The drying main chamber 100 has an inner cavity. From front to back, the drying main chamber 100 includes a feeding chamber 110, a warming chamber 120, a high-heat chamber 130, and a discharge chamber 140. A warm air duct 121 is installed on the warming chamber 120, connected to a warm air source. A high-heat air duct 131 is installed on the high-heat chamber 130, also connected to a high-heat air source. A drum screen 200 is located on the upper side inside the warming chamber 120, with its front and rear ends respectively... As the drum inlet 201 and drum outlet 202, the drum motor 240 drives the drum screen 200 to rotate around the drum shaft 230. The drum shaft 230 is inclined from the upper front side to the lower rear side. The drum wall of the drum screen 200 is distributed with screen holes 211. The vibrating screen plate 300 is located below the drum screen 200. The vibrating screen plate 300 is controlled to vibrate by the vibrator 310. The vibrating screen plate 300 has a screen plate inclined surface 320, which is inclined from the upper front side to the lower rear side.

[0030] For example, such as Figure 1 and Figure 2 As shown, the drying main chamber 100 has an inner cavity and includes, from front to back, a feeding chamber 110, a warming chamber 120, a high-heating chamber 130, and a discharging chamber 140. Feed can be processed sequentially through the feeding chamber 110, warming chamber 120, high-heating chamber 130, and discharging chamber 140 via a conveyor line 160 or other conveying devices. The warming chamber 120 is equipped with a hot air duct 121, which is connected to a hot air source to inject warm air into the chamber for heating. The high-heating chamber 130 is equipped with a high-heat air duct 131, which is connected to a high-heating air source to inject high-heat air into the chamber for heating. The drum screen 200 is located on the upper side inside the heating chamber 120. The front and rear ends of the drum screen 200 serve as the drum inlet 201 and the drum outlet 202, respectively. The drum motor 240 drives the drum screen 200 to rotate around the drum shaft 230, which is inclined from the upper front to the lower rear. The drum wall of the drum screen 200 has screen holes 211 distributed on it. The vibrating screen plate 300 is located below the drum screen 200. The vibrating screen plate 300 is controlled to vibrate by the vibrator 310. The vibrating screen plate 300 has a screen plate inclined surface 320, which is inclined from the upper front to the lower rear.

[0031] In actual operation, the feed enters the drying main chamber 100 from the feeding chamber 110, first entering the warming chamber 120 for preheating with warm air. After entering the drum screen 200 from the drum inlet 201, the rotation of the drum screen 200 causes the feed to tumble, and simultaneously the feed slides along the inclined drum screen 200 towards the high-heat chamber 130. During the tumbling process of the drum screen 200, small particles of feed pass through the sieve holes 211 and fall onto the vibrating screen plate 300 below, while large particles of feed are discharged from the drum outlet 202 along the drum screen 200.

[0032] Through the above processing method, the feed is preheated in the heated chamber 120 to evaporate the moisture in the feed first, avoiding clumping caused by direct heating and drying. In addition, the feed is screened by the drum screen 200, which processes large feed particles, and the vibrating screen plate 300 processes small feed particles. This not only makes the feed dry more thoroughly, but also further avoids feed clumping.

[0033] In some embodiments of this utility model, the warm air injected by the warm air source is 50~60°C, while the high-temperature air injected by the high-temperature air source is 90~150°C.

[0034] In some embodiments of this utility model, support rings are provided at both the front and rear ends of the roller mesh 200, and the inner sidewall of the support ring is connected to the roller shaft 230 through a support frame to ensure that the structural strength of the roller mesh 200 on the roller shaft 230 is sufficient and reliable.

[0035] In some embodiments of this utility model, the roller screen 200 includes a mesh cylinder wall 210 and a support frame 220. The screen holes 211 are located on the mesh cylinder wall 210, and the support frame 220 is connected to the inner side wall of the mesh cylinder wall 210. The mesh cylinder wall 210 plays the role of strengthening the cylinder structure of the roller screen 200.

[0036] In some embodiments of this utility model, a rotating plate 221 is provided inside the drum mesh 200. The rotating plate 221 is connected to the support frame 220 and can rotate with the drum mesh 200. In this way, during the rotation of the drum mesh 200, in addition to using the friction between the inner wall of the drum mesh 200 and the feed to turn the feed, the rotating plate 221 can also turn the feed, ensuring that the feed is more fully heated and dried.

[0037] In some embodiments of this utility model, a suspension 250 is provided on the upper side of the inner wall of the drying main chamber 100. The suspension 250 is connected to the drum shaft 230 through a bearing 251, so that the drum mesh 200 can work suspended in the drying main chamber 100 without occupying the space on the lower side of the heating chamber 120, making the structure more compact.

[0038] In some embodiments of this utility model, the vibrating screen plate 300 is provided with vent holes, so that warm air can be blown upward from the lower side of the vent holes onto the fine particle feed on the vibrating screen plate 300.

[0039] In some embodiments of this invention, a transfer chamber 150 is provided between the warm chamber 120 and the high-heat chamber 130. A transfer device 151 is installed inside the transfer chamber 150. The transfer inlet 152 of the transfer device 151 is located below the transfer chamber 150, and the transfer outlet 153 of the transfer device 151 is located above the high-heat chamber 130. That is, the feed processed by the drum screen 200 and the vibrating screen plate 300 is first concentrated in the transfer chamber 150. Then, the transfer inlet 152 of the transfer chamber 150 sucks in the feed and sends it to the upper part of the high-heat chamber 130 for spraying. This is more conducive to the processing of the feed in the high-heat chamber 130, further ensuring more thorough drying of the feed.

[0040] In some embodiments of this utility model, reference is made to Figure 3 The transfer device 151 adopts either a screw feeding device or an exhaust pipe device. The screw feeding device uses a feeding screw to convey feed, while the exhaust pipe device uses a fan to draw in feed and then convey it.

[0041] In some embodiments of this utility model, a stirrer 400 is provided inside the high-heat chamber 130. The stirrer 400 includes a stirring motor 420 and a vertical stirring shaft 410. The stirring motor 420 drives the vertical stirring shaft 410 to rotate. Stirring rods 440 are distributed on the vertical stirring shaft 410, and an arc-shaped stirring plate 450 is provided on the stirring rods 440. The two ends of the arc-shaped stirring plate 450 are connected to the ends of the stirring rods 440 and the outer wall of the vertical stirring shaft 410, respectively. After the stirring motor 420 drives the vertical stirring shaft 410 to rotate, it drives the stirring rods 440 and the arc-shaped stirring plate 450 to rotate together, stirring the feed to improve the feed drying efficiency. The structure of the stirring rods 440 and the arc-shaped stirring plate 450 ensures that the arc-shaped stirring plate 450 has sufficient structural strength to stir the feed. In particular, the arc-shaped stirring plate 450 can be designed to be larger to improve the stirring efficiency.

[0042] In some embodiments of this invention, a spiral auger blade 460 is also provided on the outer wall of the vertical stirring shaft 410. The spiral auger blade 460 has a spiral blade surface 461, which can guide the feed upward. In this way, when the stirring motor 420 drives the vertical stirring shaft 410 to rotate, it also drives the spiral auger blade 460 to rotate. The spiral blade surface 461 can bring the feed concentrated around the vertical stirring shaft 410 to the upper surface, where it comes into contact with hot air for drying.

[0043] Other components and operations of the drying apparatus according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
