High-efficiency vertical suspension following current dryer
Technical field
The utility model relates to a kind of dryer for material drying, particularly a kind of high-efficiency vertical suspension following current dryer.
Background technology
Existing tower drier, generally comprises housing, feed pipe, reclaiming cone, exhaust duct, air inlet, multicomponent castor bean cone and lubricating substance comb basin.Feed pipe and exhaust duct are all arranged on the top of housing, and multicomponent castor bean cone and lubricating substance comb basin are arranged on the inside of housing from top to down, and reclaiming cone is arranged on the lower end of housing, and the below of reclaiming cone is provided with discharge nozzle, and air inlet is arranged on the bottom of housing.During work, in air inlet enters housing, it flows to as from below to up high-temperature hot-air, material passes through feed pipe by elevator and enters in housing, during from top to down through multicomponent castor bean cone and lubricating substance comb basin whereabouts, carry out heat exchange with high-temperature hot-air from below to up, make the moisture evaporation in material, the moisture evaporating is discharged from exhaust duct with high-temperature hot-air, material falls in reclaiming cone, through discharge nozzle, discharges.Humidity maximum while entering housing due to material, the temperature of high-temperature hot-air when air inlet enters housing is the highest, and material just meets with the high-temperature hot-air entering while dropping to bottom in above-mentioned dryer housing, is obviously unfavorable for the oven dry of material.In fact, material, when entering in housing, needs most the hot blast that temperature is the highest and carries out heat exchange with it, and reason is humidity of materials maximum now, and therefore the flow direction of above-mentioned material is contrary with the flow direction of high-temperature hot-air, is unfavorable for the oven dry of material, and drying efficiency is low.Meanwhile, due to multicomponent castor bean cone and lubricating substance comb basin being housed in above-mentioned dryer, not only complex structure, affects material and high-temperature hot-air and carries out heat exchange, and drying efficiency is low, and fault rate is high, putty phenomenon very easily occurs.

Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-efficiency vertical suspension of the utility model following current dryer.
The specific embodiment
In Fig. 1, a kind of high-efficiency vertical suspension following current dryer, contains main pipeline 8 and hot bellows 2.The interior bottom of main pipeline 8 is provided with upper cone 7, middle cone 6 and lower cone 5 successively.The end opening suitable for reading and middle cone 6 of lower cone 5 is identical and connected, and the end opening of the suitable for reading and upper cone 7 of middle cone 6 is identical and connected, and the endoporus of the suitable for reading and main pipeline 8 of upper cone 7 is identical, and on the endoporus that is arranged on main pipeline 8 suitable for reading of upper cone 7.Upper cone 7 is the cone structure larger than end opening suitable for reading, and middle cone 6 and lower cone 5 are suitable for reading than lower young cone structure.The upper end of hot bellows 2 is provided with air outlet, and the lower end of hot bellows 2 is provided with slag-drip opening, and the side of hot bellows 2 is provided with air inlet 3, and the air outlet of hot bellows 2 is connected with the end opening of lower cone 5.In hot bellows 2, be provided with wind deflector 4, this wind deflector 4 is provided with scum hole, and the slag-drip opening of hot bellows 2 is provided with the cone 1 of slagging tap.The bottom of main pipeline 8 is provided with feed pipe 12, and this feed pipe 12 is tilting on main pipeline 8, and the outlet 10 of this feed pipe 12 is positioned at the top suitable for reading of described upper cone 7.The tilting angle on main pipeline 8 of described feed pipe 12 can be 25 ° to 45 °.In order to improve further raising drying efficiency and to prevent that material is bonded on the inwall of feed pipe 12, described feed pipe 12 is provided with gas bypass import 11, to improve the temperature of feed pipe 12 inwalls.Described wind deflector 4 can be arc wind waveguide plate.For increasing heat insulation effect, the outer surface of described main pipeline 8 bottoms is provided with refractory material 9.For reducing the wearability of the mobile resistance of high-temperature hot-air and enhancing main pipeline 8 internal upper parts, the top of described main pipeline 8 is curved pipe, and its inside is provided with wear-resistant liner 13.The suitable for reading of described lower cone 5 can be connected with the end opening of middle cone 6 by transition conduit 14.Described lower end of slagging tap cone 1 can be provided with air valve.During above-mentioned high-efficiency vertical suspension following current dryer work, high-temperature hot-air enters from the air inlet 3 of hot bellows 2, while moving upward through lower cone 5, middle cone 6 and upper cone 7, first the wet stock entering with the outlet 10 of feed pipe 12 meets and carries out heat exchange, material moisture temperature the highest, high-temperature hot-air is now the highest, moisture in material is evaporated rapidly, therefore greatly improved drying efficiency.Meanwhile, the high-temperature hot-air that the gas bypass import 11 being provided with from feed pipe 12 enters, has further accelerated the evaporation of moisture in material, thereby is conducive to the raising of drying efficiency.The bore suitable for reading that middle cone 6 is less, make the high-temperature hot-air rising form high-speed and high-temperature air-flow, this high-speed and high-temperature air-flow not only promotes material and moves upward, realize forward flowing of material and high-temperature hot-air, and high-speed and high-temperature gas shock material fully disperses material, be suspended in completely in main pipeline 8 and carry out sufficient heat exchange with high-temperature hot-air, compared with existing skill, material is not hindered by any parts in motion process, not only be conducive to the raising of drying efficiency, and can avoid occurring putty phenomenon.The dust collection device that the material of drying enters downstream with high-temperature hot-air from main pipeline 8 outflows is collected.The material that in material, particle is larger falls into the cone 1 of slagging tap and concentrates discharge.Because above-mentioned high-efficiency vertical suspension following current dryer only consists of main pipeline 8, hot bellows 2, feed pipe 12 and three cones, therefore not only simple in structure, and also operation expense is low, and board running rate is high.
