Abstract
The utility model discloses a device for recovering hot dust of secondarily-dried fertilizer. The device comprises a drum used for secondarily-dried fertilizer, and a drum driving device, wherein the feeding end of the drum is provided with a feeding mechanism and a hot air inlet, the discharging end of the drum is provided with an air inlet and a discharging nozzle, the feeding mechanism is located on the end face of the drum, the hot air inlet and the air inlet are formed in the upper portion of the drum, the discharging nozzle is formed in the lower portion of the drum, the air inlet is connected with a settling chamber through an air inlet pipeline, an air blower used for blowing air into the drum is installed on the air inlet pipeline, air blown in through the air inlet pushes hot dust generated by the secondarily-dried fertilizer in the drum to the discharging nozzle, and the hot dust is conveyed by the discharging nozzle to a feeding port of a granulator. According to the device for recovering the hot dust of the secondarily-dried fertilizer, due to the fact that the air blower used for blowing air into the drum is additionally arranged on the air inlet pipeline, air flow on the tail portion of the drum is slowed down, pressure of hot dust for entering the pipeline and intensity of the settling chamber are reduced, and the labor intensity for cleaning the settling chamber is reduced.
Description
Technical field
The utility model relates to fertilizer dust recovery technology field, relates in particular to a kind of hot dust retracting device of redrying fertilizer.
Background technology
In chemical production field, fertilizer needed to do dry processing before entering lower one granulating working procedure, to meet the needs of working condition.In the situation that fertilizer primary drying is not up to standard, need redrying, because the dust fabric that redrying fertilizer produces is more, general manufacturer can increase a pipeline at drying drum end dust fabric is introduced in expansion chamber and reached dust fabric is recycled.Because dried dust fabric is the floating thing with heat, make to enter the pressure of pipeline and the strength increase of expansion chamber, also strengthened the labour intensity of cleaning expansion chamber simultaneously.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of hot dust retracting device of redrying fertilizer, reached hot dust has directly been recycled, reduced the labour intensity of cleaning expansion chamber.
The hot dust retracting device of a kind of redrying fertilizer the utility model proposes, comprise the cylinder for redrying fertilizer, and drum drive, cylinder is arranged on drum rotating and supports, inner wall of rotary drum is provided with spiral plate, cylinder feed end is provided with feeding mechanism and hot blast import, cylinder discharge end is provided with air inlet and blanking mouth, feeding mechanism is positioned on the end face of cylinder, hot blast import and air inlet are positioned at cylinder top, blanking mouth is positioned at cylinder below, air inlet is connected with expansion chamber by intake stack, on intake stack, be provided with towards the air blast that is blown into air in cylinder, the hot dust that the air that air inlet is blown into produces the redrying fertilizer in cylinder is pushed into blanking mouth place, blanking mouth is transported to hot dust by conveying mechanism the charging aperture of comminutor.
Preferably, described feeding mechanism is the feeding screw with charging aperture and discharging opening, at feeding screw discharge port end, extruding disk is installed, and extruding disk is provided with extruded hole.
Preferably, described cylinder is connected as one by least two cylinder joint head and the tail, and each cylinder joint is equipped with spiral plate, and the spiral plate rotation direction in each cylinder joint is consistent.
Preferably, described conveying mechanism is connected with the charging aperture of comminutor by classified screening device.
Preferably, conveying mechanism comprises conveyer belt, and described conveyer belt is placed in pipeline.
The hot dust retracting device of a kind of redrying fertilizer that the utility model provides; by increasing by one to the air blast that is blown into air in cylinder on intake stack; slow down the Air Flow of cylinder afterbody; make hot dust automatically freely pass to conveyer belt below blanking mouth; through tape transport, after classifying screen, enter immediately comminutor hot side material again; be convenient to granulation, conveyer belt is placed in pipeline, in order to avoid hot dust pollutes working environment.The utility model has reached and has reclaimed the hot dust that redrying fertilizer produces, and reduces pressure and expansion chamber intensity that hot dust enters pipeline, reduces the labour intensity of cleaning expansion chamber.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hot dust retracting device of a kind of redrying fertilizer that the utility model proposes.
The specific embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the hot dust retracting device of a kind of redrying fertilizer that the utility model proposes.
With reference to Fig. 1, the hot dust retracting device of a kind of redrying fertilizer the utility model proposes, comprise the cylinder 1 for redrying fertilizer, and drum drive 2, cylinder 1 is arranged on drum rotating and supports, cylinder 1 inwall is provided with spiral plate 3, cylinder 1 feed end is provided with feeding mechanism 4 and hot blast import 5, cylinder discharge end is provided with air inlet 6 and blanking mouth 7, feeding mechanism 4 is positioned on the end face of cylinder 1, described feeding mechanism 4 is the feeding screw with charging aperture and discharging opening, at feeding screw discharge port end, extruding disk 41 is installed, extruding disk 41 is provided with extruded hole.Hot blast import 5 and air inlet 6 are positioned at cylinder 1 top; blanking mouth 7 is positioned at cylinder 1 below; air inlet 6 is connected with expansion chamber 9 by intake stack 8; on intake stack 8, be provided with towards the air blast 10 that is blown into air in cylinder 1; the hot dust that the air that air inlet 6 is blown into produces the redrying fertilizer in cylinder 1 is pushed into blanking mouth 7 places, and blanking mouth 7 is transported to hot dust by conveying mechanism 11 charging aperture of comminutor.Described conveying mechanism 11 is connected with the charging aperture of comminutor by classified screening device 12, and conveying mechanism 11 comprises conveyer belt, and described conveyer belt is placed in pipeline.
The hot dust retracting device of a kind of redrying fertilizer that the utility model provides; by increasing by one to the air blast 10 that is blown into air in cylinder 1 on intake stack 8; slow down the Air Flow of cylinder 1 afterbody; make hot dust automatically freely pass to blanking mouth 7 conveyer belt below; through tape transport, after classifying screen, enter immediately comminutor hot side material again; be convenient to granulation, conveyer belt is placed in pipeline, in order to avoid hot dust pollutes working environment.The utility model has reached and has reclaimed the hot dust that redrying fertilizer produces, and reduces pressure and expansion chamber 9 intensity that hot dust enters pipeline, reduces the labour intensity of cleaning expansion chamber 9.
