Description

Tower drier

Technical field

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

Background technology

Iron ore becomes iron extract mine producation behind processing, wet concentration.Have a large amount of interstitial waters at the ore in sand form intergranular, if do not do processed, in transit, iron sand is prone to lose with current, causes loss of enterprises, and also pollutes environment in the way.When prior art is carried out processed to iron ore concentrate, adopt the dehydration of sedimentation basin deposition usually, perhaps adopt the filtering equipment filtering means dehydration.Wherein, the sedimentation basin deposition dehydrating is applied in small-sized ore dressing plant mostly, and suitable granularity is that 50 orders use with interior iron ore concentrate dehydration, though this method production cost is lower, the sedimentation time is long, and deviates from for being difficult to nature less than 50 purpose granularities; Generally adopt the filtering equipment dehydration than mammoth mill, the dehydration indexes of press filtration method is good, but equipment investment is big, and production cost is high, stops up, damages because of parts such as filter screen are easy again, need to shut down repairing, change part, thereby the production poor continuity.

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

Summary of the invention

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

Further, the defeated material of said rotation chamber 3 upper and lower sides also comprise a plurality of revolution support wheels, and said revolution support wheel is provided support by the supporting seat on the frame.

The present invention has advantage 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 dewatering, thermal current flows in interior fixedly drying chamber from bottom to top, and iron ore concentrate is indoor mobile from top to bottom at the defeated material of rotation, and heat exchange is evenly abundant, and dewatering efficiency is high;

3, novelty ground the defeated material of rotation chamber housing and in fixedly open the groove of a plurality of circulation hot gas on the face of cylinder of drying chamber housing; Thermal current can get in the defeated material of the rotation chamber through this groove; And be penetrated into the inside of mineral aggregate through the slit between the iron ore concentrate material; Thereby make that dehydration is more thorough, drying effect obviously improves.

Feed hopper 1, frame 2, the defeated material of rotation chamber 3, drive motors 4, discharging opening 5, interior fixedly drying chamber 6, heating stove 7, the defeated material of rotation 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 be discussed in more detail the present invention in conjunction with the accompanying drawings.

Like accompanying drawing 1, shown in 2, tower drier of the present invention comprises: feed hopper 1, frame 2, the defeated material of rotation 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 the defeated material of rotation chamber 3; The defeated material of rotation chamber 3 is the vertical type cylinder structure; It comprises the defeated material of rotation chamber housing 8, spiral pusher plate 10 and rotation fluted disc 11; The rotation fluted disc 11 defeated material of related whole rotation chamber 3 under the driving of drive motors 4 rotates; Iron ore concentrate in the defeated material of the rotation chamber 3 transports under the promotion of spiral pusher plate 10 from top to bottom, and discharges dryer through the discharging opening 5 of lower end; Interior fixedly drying chamber 6 is positioned at the defeated material of rotation 3 inside, chamber; Be the hollow circuit cylinder structure; It comprises interior fixedly drying chamber housing 12, heating stove 7 and exhaust outlet 13, and the bottom and the heating stove 7 of interior fixedly drying chamber housing 12 are affixed, and the hot gas of dry iron ore concentrate can flow therein from bottom to top; The interior fixedly top of drying chamber housing 12 links to each other with exhaust outlet 13, is used for thermal current is discharged dryer; It is characterized in that: the defeated material of rotation chamber housing 8 and in fixedly on the face of cylinder of drying chamber housing 12; Have the groove 9 of a plurality of circulation hot gas; And the groove 9 on the interior fixedly drying chamber housing 12 is downward-sloping setting, gets into groove 9 to prevent mineral aggregate, the setting that is inclined upwardly of the groove 9 on the defeated material of the rotation chamber housing 8; Help water vapour and discharge, prevent descending mineral aggregate effusion simultaneously.The defeated material of said rotation chamber 3 upper and lower sides also comprise a plurality of revolution support wheels 14, and said revolution support wheel 14 is provided support by the supporting seat on the frame 2 15.

The course of work of this tower drier is following:

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

2, with the iron ore concentrate material by the feed hopper 1 defeated material of the rotation chamber 3 of packing into, under the appendix of spiral pusher plate 10, mineral aggregate is moved along the helical orbit from top to down equably in the defeated material of rotation chamber 3;

3, thermal current enters in the defeated material of the rotation chamber 3 through the surface groove of interior fixedly drying chamber housing 12; Come in contact with descending mineral aggregate; And gasify the moisture in the mineral aggregate; Groove via on the defeated material of the rotation chamber housing 8 is discharged dryer, and the thermal current that does not see through interior fixedly drying chamber housing 12 is then discharged dryer by exhaust outlet 13;

4, discharge tower stove through the iron ore concentrate material of abundant processed through discharging opening 5.

Constantly inwardly fixedly feed intake the drying chamber from feed hopper, after oven dry, mineral aggregate is constantly discharged through discharging opening, realized lasting drying course, improved the operating efficiency of handling mineral aggregate the iron ore concentrate material.
