DETAILED DESCRIPTION

[0015] like Figure 1 to Figure 2 A vertical partition silo dryer is shown, characterized in that: a feed port 11 is arranged on the outer wall of the silo 3, an air supply duct 2 is arranged on the outer wall of the silo 3, the air supply duct 2 is connected to a hot air source 1, and hot air enters the silo 3 through the air supply duct 2, and a silo support plate 10 supported by a pressure spring is arranged at the bottom of the silo 3, and the silo support plate 10 is controlled to open and close by the weight of the material, thereby controlling the discharge of the material in the silo 3.

[0016] A middle tube 5 is arranged in the silo 3, and the bottom of the middle tube 5 is connected with the feed port 11. A plurality of positive pressure partitions 4 and negative pressure partitions 7 are arranged in the silo 3, and the positive pressure partitions 4 are connected with the air supply duct 2, and the negative pressure partitions 7 are connected with the middle tube 5. After the hot air enters the positive pressure partition 4, it passes through the material and is sucked into the middle tube 5 by the negative pressure partition. The height of the positive pressure partition 4 and the negative pressure partition 7 is 3 / 4 of the height of the silo 3, and the positive pressure partition 4 and the negative pressure partition 7 are made of ventilation material. A silo bottom support plate 9 is arranged at the bottom of the middle tube 5, and a discharge port 8 is arranged below the silo bottom support plate 9 for material discharge, and the silo bottom support plate 9 and the discharge port 8 are opened and closed by manual control.

[0017] An elevator 6 is arranged in the middle cylinder 5 , and the elevator 6 lifts the materials at the bottom of the middle cylinder 5 and pours them into the silo 3 for drying. A dehumidification fan 12 is arranged on the top of the middle cylinder 5 .

[0018] A hot air source outlet is provided at the lower part of the middle tube 5, and the hot air source outlet is connected to the air inlet of the fan, and the air outlet of the fan is connected to the hot air source 1 to provide a circulation operation of the hot air.

[0019] In the embodiment, the material is poured into the middle tube 5 through the feed port 11. At this time, the silo support plate 10 is in a closed state. The fan and the elevator 6 are started. The elevator 6 lifts the material at the bottom of the middle tube 5 and pours it into the silo 3. Because the height of the positive pressure partition 4 and the negative pressure partition 7 is 3 / 4 of the height of the silo 3, the material will accumulate in the silo 3 and exceed the height of the partition. Then, it will flow to the remaining space of the silo 3 and finally fill up the silo 3. The silo support plate 10 supported by the pressure spring allows the material to slide to the bottom of the middle tube 5, be lifted by the elevator and backfilled into the silo 3, and the fan sends the hot air into the air supply duct 2 through the hot air source 1, and flows into the positive pressure partition 4, and then into the silo 3, and then flows into the middle tube 5 through the negative pressure partition 7, and finally flows back to the fan through the negative pressure channel provided at the bottom of the middle tube 5, forming a hot air circulation operation to dry the material in the silo 3.

[0020] After the material is dried, the bottom support plate 9 and the discharge port 8 are manually opened in sequence, and the dried material flows out of the middle cylinder 5 through the discharge port 8. During the drying operation, the dehumidification fan 12 is periodically used according to the baking process requirements. The dehumidification fan 12 can discharge the moisture generated in the middle cylinder 5 to achieve the purpose of drying.

[0021] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
