The process that adopts described multistage drying system to dry comprises following steps:

Step 11: from charging aperture input material particles, described material particles enters first tapered portion under the gravity effect.

Step 12: the top rotating shaft drives the cage whirligig rotation that connects on it, each support of this cage whirligig and on the dispersion tooth the rotation process in, with being distributed in the material particles dispersion of first tapered portion and whereabouts and kicking up, make material particles be well dispersed in drying chamber inside.

Step 13: the gas that input has uniform temperature humidity in axocoel, the unidirectional hole that this gas passes on the axle housing outwards sprays, mix mutually with the material particles that is dispersed in drying chamber inside and kicked up, make material particles under the effect of this gas, its surface is dried rapidly, with avoid between material particles be stained with sticking.

Step 14: the gear that the top rotating shaft drives on it is that rotate in the axle center with the top rotating shaft, and gear driven first gear rotates, first gear driven, second gear rotates.The rotation of first gear further drives first rotating shaft himself be that rotate in the axle center, the rotation of second gear further drive second rotating shaft himself being that rotate in the axle center, and switched in opposite.The bottom rotating shaft to be rotating with the direction of top rotating shaft switched in opposite, and to drive sealing device, first rotating shaft and second rotating shaft successively be that rotate in the axle center with the bottom rotating shaft.

Step 15: the impeller that first rotating shaft drives on it is that rotate in the axle center with first rotating shaft, and impeller is realized multidirectional rotation along with first rotating shaft is that rotate in the axle center with the bottom rotating shaft simultaneously.The impeller that second rotating shaft drives on it is that rotate in the axle center with second rotating shaft, and impeller is realized multidirectional rotation along with second rotating shaft is that rotate in the axle center with the bottom rotating shaft simultaneously.

Step 16: the material particles that passes cage whirligig whereabouts is further disperseed under the multidirectional rotation of each impeller of first impeller sets and second impeller sets is stirred, to avoid intergranular bonding.

Step 17: the material particles that passes first impeller sets and second impeller sets is assembled in second tapered portion bottom, and exports by discharging opening.

Step 18: enter described pusher transmission pipeline from described discharging opening outputting material, its inner feeding spiro rod rotates under extraneous driven by motor and pushes ahead material by each helical structure on it and pass conveying pipeline, thereby material is transferred to the charging aperture of tower type drying system.

Step 21: from each material charging aperture input material particles to be dried of described charging aperture, described material particles passes the material charging aperture, and along with this material charging aperture sidewall, drop in the pairing first order flow dividing structure.

Step 22: each flow dividing structure that described rotating shaft drives the shunting material channel that connects on it is that rotate in the axle center with the rotating shaft.Because the shunting grid of each flow dividing structure and horizontal plane maintain the inclination angle of 40 °～80 ° or 100 °～140 °, so described material particles under the rotary action of gravity effect and rotating shaft, is shunted grid downslide along each of flow dividing structure.Because forward flow dividing structure and reversed shunt structure are alternately arranged, and it is interlaced between adjacent forward shunting grid and the reversed shunt grid, thereby make the material particles that slides from the upper level flow dividing structure when entering the opposite flow dividing structure of next stage direction, shunted reorganization in the interlaced area of two flow dividing structures.

Step 23: the gas that has uniform temperature humidity from the input of the gas feed mouth of described charging aperture, the unidirectional hole that this gas passes on the axle housing outwards sprays, mix mutually with the material particles in the shunting that is dispersed in inner each flow dividing structure of tower drying chamber, make this material particles under the effect of gas, be dried.

Step 24: described material particles glides along flow dividing structure, in the downslide process, gone out the gas drying of ejection from unidirectional hole, then along the space bar with the terminal adjacent discharging opening of flow dividing structure fall to the corresponding apotheca of this flow dividing structure in, subsequently from being positioned at the material discharging opening output of apotheca bottom.

Step 25: the wind that has uniform temperature humidity and speed from the input of the air inlet of described rotation wind generation apparatus, described wind rotates in snail shape air channel delivered inside and along snail shape air channel, discharge from air outlet subsequently, the wind that discharge this moment is the rotation wind with certain speed and angle, this rotation wind rotates up along the inwall of tower drying chamber, and the material particles that will be bonded on the tower drying chamber inwall is swept down.

Step 26: the described drawing-in type transmission pipeline externally effect of bleeding of evacuator produces down low pressure, and pressure discharging opening on the housing sidewall and the discharging opening on the bottom are pumped to the material of tower type drying system inside in the conveying pipeline.

When the big and swabbing action of material surface viscosity is more weak, the fast screw rod of described control is rotated in the forward under extraneous driven by motor, material is pushed ahead, accelerate the flow velocity of material, when the less and swabbing action of material surface viscosity is strong, the reverse rotation under extraneous driven by motor of the fast screw rod of described control imposes resistance to material, slows down the flow velocity of material.

Externally bleeding of evacuator acts on and controls under the forward or counter-rotating effect of fast screw rod, and material transfers to the charging aperture of box type multi-stage drying system from tower type drying system.

Because the different conveying pipelines of described drawing-in type transmission pipeline connect different charging apertures, the material of transmission can the corresponding different layers that transfers to the box type multi-stage drying system.

Step 31:, material particles to be dried is input on the conveyer belt with the corresponding drying chamber of this charging aperture by each charging aperture of feed system.

Step 32: conveyer belt under the drive of transmission shaft, the side shifting backward from the front side of casing, in this process, material particles covers full conveyer belt gradually.

Step 33: the gear of conveyer belt and transmission shaft is meshing with each other, and moves to assigned position so that transmission shaft drives conveyer belt synchronously, and promptly each opening on the conveyer belt and corresponding sealed gate in the vertical direction are overlapping.

Step 34: the lifting motor of gate inside, following one deck top drive elevating lever with and go up the bottom gate that connects and rise, eject from this time one deck top gate is inner, pass on the driving-belt corresponding opening, rise and carry out the inclined-plane seal closure with respective upper gate with one deck.

Step 35: after treating each sealed gate closure, oven dry with uniform temperature humidity enters into dividing wall inside with gas from each air admission hole on dividing wall top, discharge by each pore on left side body of wall and the right side body of wall subsequently, so that gassy in each airtight relatively independent drying chamber, thereby oven dry material particles.After drying time finishes, by each steam vent on dividing wall top, utilize the above-mentioned pore on the body of wall again, each drying chamber gas inside is taken away.Because each drying chamber is relatively independent and airtight, and described sealing supplementary structure to be a kind of closed-in construction be separated into the interior zone that one group of inside is separate, not exchange information with dividing wall inside, and scope that should the zone is identical with the drying chamber scope, so air admission hole and steam vent by each interior zone top can carry out oven dry in various degree to the inner gas that injects different temperatures humidity of each drying chamber.

Step 36: in above-mentioned drying course, by the gas stirring system, the gas that will have certain pressure is gone out from the unidirectional hole on the conveyer belt, and the material on the conveyer belt is stirred in upset.

Step 37: after the end of waiting to bleed, the lifting motor of gate inside, following one deck top drive elevating lever with and go up the bottom gate that connects and descend, be separated from each other with respective upper gate with one deck, pass on the driving-belt corresponding opening, descend and be retracted to the corresponding hollow inside of one deck top gate down.

Step 38: this moment, each sealed gate was opened, and conveyer belt continues to move under the drive of transmission shaft, material particles is sent in the next drying chamber dries.

Step 39: will dry good material particles and output to each discharging opening place with the corresponding discharge system of this conveyer belt, thereby material particles is exported by conveyer belt.

Because the utility model has adopted the prebake system that material is carried out prebake, reduce its surperficial water content fast, can effectively avoid the surface to have between the full-bodied material particles that bonding is agglomerating mutually, thereby make material particles can inadherently mutually enter tower drying system, under its high temperature action, evenly dry, material particles after the oven dry is transferred into the box type multi-stage drying system lowers the temperature slowly step by step in having the multistage drying chamber of different temperatures humidity and dries, thereby makes that the water content of last material particles is stable and avoid surface checking.

Step 17: the material particles that passes first impeller sets 1041 and second impeller sets 1042 is assembled in second tapered portion, 1014 bottoms, and by discharging opening 1015 outputs.

Step 18: enter described pusher transmission pipeline 501 from described discharging opening 1015 outputting materials, its inner feeding spiro rod rotates under extraneous driven by motor and pushes ahead material by each helical structure on it and pass conveying pipeline, thereby material is transferred to the charging aperture 203 of tower type drying system 2.

According to Fig. 1, Fig. 4, Fig. 5 a～5h, Fig. 6, Fig. 7, Figure 13 c, 13d:

Step 21: from each material charging aperture 2035 inputs material particles to be dried of described charging aperture 203, described material particles passes material charging aperture 2035, and along with these material charging aperture 2035 sidewalls, drop in the pairing first order flow dividing structure 2050.

Step 22: each flow dividing structure 2050 that described rotating shaft 202 drives the shunting material channel 205 that connects on it is that rotate in the axle center with rotating shaft 202.

Because the shunting grid of each flow dividing structure 2050 and horizontal plane maintain the inclination angle of 40 °～80 ° or 100 °～140 °, so described material particles under the rotary action of gravity effect and rotating shaft 202, is shunted grid downslide along each of flow dividing structure 2050.
