Example Embodiment

[0016] Reference figure 1 , An energy-saving dryer used in chemical production, including a drying box 1, a spin-drying barrel 2, a dehumidification fan 3, a driving device 4, a suction tube 5, a suction fan 6, and a cyclone 7.
[0017] The drying box 1 has a first partition and a second partition. The first partition and the second partition divide the drying box 1 from top to bottom into a dehydration box 11, a drying box 12 and a receiving box 13, and the dehydration box 11 The drying box 12 and the receiving box 13 communicate with each other through a first opening on the first partition and a second opening on the second partition. A number of heaters 14 are provided on the inner wall of the drying box 12, and the bottom of the receiving box There is a discharge port, and a receiving funnel is arranged under the drying box 1. The outlet of the receiving funnel is connected to the inlet of the cyclone separator 7 through the suction pipe 5, and the outlet of the cyclone separator 7 is connected to the suction fan 6 through the air pipe. The air inlet is in communication, and the air outlet of the suction fan is in communication with the inlet in the first rotating shaft 21.
[0018] The spin-drying bucket 2 is of a truncated cone shape. The top of the spin-drying bucket 2 is provided with a centrifugal disk, which has a cone shape. The side wall of the spin-drying bucket 2 is composed of a water filtering structure 21 at the upper part and a steel plate structure 22 at the lower part. The lower end of the spin-drying barrel 2 is provided with a discharge port. The spin-drying barrel 2 is arranged in the drying box 1 and rotatably cooperates with the first opening and the second opening. The upper end of the spin-drying barrel 2 is provided with a first rotating shaft 23, and the lower end A second rotating shaft 24 is provided. The drying bucket 2 is movably connected to the drying box 1 through a first rotating shaft 23 and a second rotating shaft 24. The first rotating shaft 23 extends out of the drying box 1, and the first rotating shaft 21 has an inlet inside. The driving device 4 drives the first rotating shaft 23 to drive the spin-drying barrel 2 to rotate. The drying box 1 is provided with a feeding funnel. The discharge pipe of the feeding funnel extends into the feeding port in the first rotating shaft 23. A plurality of supporting legs are arranged around the lower end of the drying box 1, and the lower ends of the supporting legs are opened outward.
[0019] There is a water outlet on the side wall of the dehydration box 12 near the first partition plate, a dehumidification opening is opened on the side wall of the drying box 12, a discharge opening is opened at the bottom of the receiving box 13, and the dehumidification opening is connected to the dehumidification through a wind pipe. Fan 3 is connected.
[0020] When working, add the materials that need to be dried into the feeding funnel, and then from the feeding funnel to the spin-drying bucket 2 through the feed port, enter the spin-drying bucket 2 and then fall onto the centrifuge plate. Due to the effect of the centrifuge plate, the material Transported to the side wall of the spin-drying barrel 2, because the spin-drying barrel 2 is in the shape of a truncated cone, under the action of centrifugation, the material moves down along the side wall of the spin-drying barrel 2, and the material is first dehydrated during the downward movement. After dehydration, it is dried. After drying, it is discharged from the discharge port at the bottom of the spin-drying barrel 2 and falls into the drying box 1 after being discharged, and is sucked into the cyclone 7 through the discharge port of the drying box 1.
[0021] The first partition and the second partition divide the drying box 1 from top to bottom into a dehydration box 11, a drying box 12, and a receiving box 13. The spin-drying barrel 2 is in the shape of a truncated cone, and the top of the spin-drying barrel 2 is provided with a centrifuge. The plate and the spin-drying bucket 2 are arranged in the drying box 1 and connected to the drying box 1 in rotation, and the driving device 4 drives the spin-drying bucket 2 to rotate. Through the above-mentioned optimized design of the dryer, the dehydration, drying and collection of the materials are integrated, saving operation time and steps, and saving a lot of energy. The dried material is sucked out by the suction fan 6 and collected in the cyclone 7 to further separate the dried material from the humid air. Feeding through the feeding funnel is convenient and fast, and the feeding efficiency is greatly increased. The drying box 1 is provided with support legs to prop up the drying box 1 to facilitate the removal of dry materials from the lower end of the drying box 1. The centrifugal disc is set into a cone shape, which makes the material distribution more even. The air outlet of the suction fan 6 is connected with the inlet, which can further utilize the waste heat and achieve the effect of energy saving.
[0022] The basic principles and main features and advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the foregoing embodiments. The foregoing embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have Various changes and improvements, these changes and improvements fall within the scope of the claimed invention.
