Abstract
The utility model relates to a general drying device for an intermittent type non strong adhesiveness high wet material and an ordinary moisture material. The utility model is composed of a forced jet bed drying device, an air inlet pipe, a combustion furnace, a changeover valve, a cyclone separator, an air exhaust pipe, a centrifugal fan, an air lock device, an electrical control cabinet, etc. The inner of the forced jet bed drying device is provided with a guide pipe which has the functions of rotation and arch breaking. The guide pipe enables the jet bed to be stably operated when the non strong adhesiveness high wet material is used. The airflow method is used for the material charging and discharging, and thus the utility model has the advantage of simple structure and failure is reduced. One cyclone separator is shared by dust collecting and material charging and thus the structure is compact. The complete machine has few machine processing components and the cost is low.
Description
The utility model belongs to drying plant.
Existing spouted bed drying equipment stops up when handling water content greater than 40% high moisture material easily, can not steady operation.
The purpose of this utility model is to provide a kind of high characteristics of spouted-bed dryer efficient that both can keep, and can be suitable for dry general humidity bulk granular material, is suitable for the batch (-type) high-efficiency energy-saving drying apparatus of dry non-strong viscosity high moisture material again.
The utility model is by forcing spray bed dryer 1 (following abbreviation drier), blast pipe 2, combustion furnace 3, switching valve 4, cyclone separator 5, exhaust duct 6, centrifugal blower 7, airlock 8 and electrical control cabinet to be formed.Rotary guide pipe 1-1 is arranged in the drier 1, the rotation transmission system 1-2 of guide pipe is arranged on the drier top, broken arch halberd 1-6 is arranged at the guide pipe bottom, the simplified 1-4 of drier is made up of cone and cylinder that steel plate is made, between dryer cartridge and the guide pipe annular tempering storehouse 1-5, dust flue 1-3 is arranged at dryer cartridge top, many siphunculus 1-7 is arranged at the simplified bottom of drier, inlet valve 1-8 is arranged at many siphunculus bottom, horizontal interface one end of many siphunculus connects discharge nozzle 1-9, and the other end connects blast pipe 2.Air intake valve 2-1 is arranged on the blast pipe, and the other end of blast pipe connects combustion furnace 3.One end of switching valve 4 links to each other with discharge nozzle 1-9 with dust flue 1-3, and the other end links to each other with cyclone separator 5.The cyclone separator bottom is an airlock 8.Cyclone separator links to each other with centrifugal blower 7 by exhaust duct 6.
Drying equipment is worked under negative pressure state.The oven dry medium that combustion furnace 3 produces enters drying system under the effect of centrifugal blower 7.Close the air intake valve 2-1 on the blast pipe 2 during charging, open inlet valve 1-8 simultaneously, the negative pressure that centrifugal blower 7 produces sucks wet stock, and 1-1 enters in the drier through guide pipe.After treating that a batch materials enters fully, close inlet valve 1-8, open air intake valve 2-1, system finishes the charging program, enters drying program.In drying program, the annular tempering storehouse 1-5 between simplified slowly moves to the guide pipe bottom to material via guide pipe and drier, is brought in guide pipe by the negative pressure hot blast again, and via guide pipe ejection suitable for reading, falls back to annular tempering storehouse again.So constantly circulation is arrived required moisture until dry materials.When the general humidity bulk granular material of drying, guide pipe does not rotate, and when dry high moisture material, guide pipe slowly runs, and this moment, the broken arch halberd 1-6 of guide pipe bottom forced broken arch, guaranteed the stable operation of spouted bed.In dry run, the dust process dust flue 1-3 and the switching valve 4 of being overflowed by drier enters cyclone separator 5 on a small quantity, discharged by airlock 8 again.Dry materials in the drier enters the discharge program behind predetermined moisture.This moment, the switching valve 4 of leaving behind cut off dust flue 1-3, opened discharge nozzle 1-9.Owing to no longer include negative-pressure air-flow in the guide pipe 1-1, after the material in the annular tempering storehouse 1-5 drops to the drier bottom, can not enter guide pipe again, and pump to cyclone separator 5, through airlock 8 dischargings by the negative-pressure air-flow among the discharge nozzle 1-9.Advantage of the present utility model and good effect:
1, spouted-bed dryer efficient height, advantage of low energy consumption have been kept;
2, enlarged the range of application of spouted-bed dryer, made water content also can use the spouted-bed dryer drying greater than 40% non-strong viscosity high moisture material;
3, adopt air-flow charging and discharging mode, rotatable parts are few, reduced equipment failure rate;
4, the shared cyclone separator of control of dust and discharge, compact conformation;
5, machined components is few, with high moisture material drying equipment such as the broken drier of cylinder relatively, cost greatly reduces.
Accompanying drawing is a structural representation of the present utility model:
1 forces spray bed dryer 2 blast pipes 3 combustion furnaces 4 switching valves 5 cyclone separators 6 exhaust ducts 7 centrifugal blowers 8 airlock 1-1 guide pipe 1-2 guide pipes to rotate many siphunculus of the broken arch of transmission system 1-3 dust flue 1-4 dryer cartridge 1-5 annular tempering storehouse 1-6 halberd 1-7 1-8 inlet valve 1-9 discharge nozzle 2-1 air intake valve
Embodiment:
Simplified diameter 900mm under the spouted-bed dryer, upper shell diameter 1500mm, guide pipe diameter 250mm; Cyclone separator diameter 800mm; The combustion furnace 750000kj/h that exerts oneself; Centrifugal blower air quantity 3215m
3/ h, total head 5057p
3Airlock volume 7L/n.
Treating capacity is 300kg/h during these drying plant drying brewex's grains; Treating capacity is 1000kg/h during drying wheat.
