Description

Tower drier

Technical field

The present invention relates to a kind of drying unit, particularly relate to a kind of tower drier for dry iron ore concentrate.

Background technology

Iron ore becomes iron extract mine producation after processing, wet concentration.At ore in sand form intergranular, have a large amount of Interstitial Waters, if do not do processed, in transit, iron sand easily outflows with water, and causes enterprises' loss, and also pollutes environment in way.When prior art is carried out processed to iron ore concentrate, conventionally adopt the dehydration of sedimentation basin precipitation, or adopt filtering equipment filtering means dehydration.Wherein, sedimentation basin deposition dehydrating is applied in small-sized ore dressing plant mostly, and to be 50 orders use with interior iron ore concentrate dehydration applicable granularity, although the method production cost is lower, the sedimentation time is long, and is difficult to nature and deviates from for being less than 50 object granularities; Relatively large ore dressing plant generally adopts filtering equipment dehydration, and the dehydration indexes of filter-pressing method is good, but equipment investment is large, and production cost is high, again because the parts such as filter screen easily stop up, damage, need to shut down repairing, change part, thereby continuous production is poor.

The present invention, in order to solve the problems of the technologies described above, provides a kind of novel vertical dryer, and this drying machine structure is simple, energy consumption is low, dewatering efficiency is high, and good drying effect.

Summary of the invention

For achieving the above object, the invention provides following technical scheme: a kind of tower drier, it comprises: feed hopper, frame, rotation conveying chamber, drive motors, discharging opening, interior fixedly drying chamber; Wherein, feed hopper is positioned at frame top, is funnel-form, and its lower ending opening joins with rotation conveying chamber; Rotation conveying chamber is vertical type cylinder structure, it comprises rotation conveying chamber housing, spiral pusher plate and rotation fluted disc, rotation fluted disc related whole rotation conveying chamber under the driving of drive motors rotates, the indoor iron ore concentrate of rotation conveying transports from top to bottom under the promotion of spiral pusher plate, and discharges dryer by the discharging opening of lower end; Interior fixedly drying chamber is positioned at rotation conveying chamber interior, for hollow circuit cylinder structure, it comprises interior fixedly drying chamber housing, heating stove and exhaust outlet, bottom and the heating stove of interior fixedly drying chamber housing are affixed, the hot gas of dry iron ore concentrate can flow therein from bottom to top, the interior fixedly top of drying chamber housing is connected with exhaust outlet 13, for thermal current is discharged to dryer; On the face of cylinder of rotation conveying chamber housing and interior fixedly drying chamber housing, have the groove of a plurality of circulation hot gas.

Further, described rotation conveying chamber 3 upper and lower sides also comprise a plurality of revolution support wheels, and described revolution support wheel is provided support by the supporting seat in frame.

The present invention has following advantages and effect:

1, tower drier of the present invention is simple in structure, easy to operate, can be widely used in the fields such as chemical industry, metallurgy;

2, in implementing the process of dehydration, thermal current flows from bottom to top in interior fixedly drying chamber, and conveying is indoor moves from top to bottom in rotation for iron ore concentrate, and heat exchange is evenly abundant, and dewatering efficiency is high;

3, on the face of cylinder of rotation conveying chamber housing and interior fixedly drying chamber housing, open innovatively the groove of a plurality of circulation hot gas, thermal current can enter in rotation conveying chamber by this groove, and by the gap between iron ore concentrate material, be penetrated into the inside of mineral aggregate, thereby make dehydration more thorough, drying effect obviously improves.

Accompanying drawing explanation

Fig. 1 is the structural representation of tower drier of the present invention;

Fig. 2 is the top view of tower drier of the present invention.

Feed hopper 1, frame 2, rotation conveying chamber 3, drive motors 4, discharging opening 5, interior fixedly drying chamber 6, heating stove 7, rotation conveying chamber housing 8, groove 9, spiral pusher plate 10, rotation fluted disc 11, interior fixedly drying chamber housing 12, exhaust outlet 13, revolution support wheel 14, supporting seat 15.

The specific embodiment

Now 1,2 elaborate the present invention by reference to the accompanying drawings.

As shown in accompanying

drawing

1,2, tower drier of the present invention comprises: feed hopper 1, frame 2, rotation conveying chamber 3, drive motors 4, discharging opening 5, interior fixedly drying chamber 6; Wherein, feed hopper 1 is positioned at frame 2 tops, is funnel-form, and its lower ending opening joins with rotation conveying chamber 3; Rotation conveying chamber 3 is vertical type cylinder structure, it comprises rotation conveying chamber housing 8, spiral pusher plate 10 and rotation fluted disc 11, rotation fluted disc 11 related whole rotation conveying chamber 3 under the driving of drive motors 4 rotates, iron ore concentrate in rotation conveying chamber 3 transports from top to bottom under the promotion of spiral pusher plate 10, and discharges dryer by the discharging opening 5 of lower end; Interior fixedly drying chamber 6 is positioned at rotation 3 inside, conveying chamber, for hollow circuit cylinder structure, it comprises interior fixedly drying chamber housing 12, heating stove 7 and exhaust outlet 13, bottom and the heating stove 7 of interior fixedly drying chamber housing 12 are affixed, the hot gas of dry iron ore concentrate can flow therein from bottom to top, the interior fixedly top of drying chamber housing 12 is connected with exhaust outlet 13, for thermal current is discharged to dryer; It is characterized in that: on the face of cylinder of rotation conveying chamber housing 8 and interior fixedly drying chamber housing 12, have the groove 9 of a plurality of circulation hot gas, and the groove 9 on interior fixedly drying chamber housing 12 is downward-sloping setting, to prevent that mineral aggregate from entering groove 9, the setting that is inclined upwardly of groove 9 on rotation conveying chamber housing 8, be conducive to water vapour and discharge, prevent descending mineral aggregate effusion simultaneously.Described rotation conveying chamber 3 upper and lower sides also comprise a plurality of revolution support wheels 14, and described revolution support wheel 14 is provided support by the supporting seat 15 in frame 2.

The course of work of this tower drier is as follows:

1, light heating stove 7 endogenous pyrogens, thermal current occurs to flow by interior fixedly drying chamber 6 from bottom to top;
