In the utility model, which further includes the discharge chute being arranged below discharge apparatus.Discharge slips The sinter that the effect of slot mainly discharges discharge apparatus is concentrated, and is then discharged by discharge gate.When the vertical cooling furnace is used When circulating cooling system, the top of discharge chute is then connect with tower body bottom, enters the wind discharge device and discharge apparatus is located at row In the space for expecting chute and bottom of towe composition, while cold wind import is set on the side wall of discharge chute, circulating cooling wind is from cold wind Import enters discharge chute, then enters inside tower body via air inlet discharge device and sinter is cooled down.
In the utility model, in order to allow air-flow and material stream evenly, which, which further includes, is arranged on tower body Internal logistics air flow controller.Logistics air flow controller includes being arranged on support construction and the setting of bottom of towe center Square top plate on the support structure, top plate are flat-tope structure or cone structure.The side of top plate goes out compression ring, top plate equipped with shutter Bottom be equipped with logistics air flow controller air inlet.After adding logistics air flow controller, center material can be made outward Shunting can make air-flow evenly, reduce cooling dead zone with material stream.And top plate side shutter goes out the setting of compression ring, it can be with The resistance that inner ring air inlet discharge device enters cooling wind in tower is reduced, is more conducive to the uniformity of tower interior air-flow distribution.
In the utility model, in order to allow air-flow evenly, which further includes the edge being arranged in tower wall Air flow regulator and the central gas stream regulating device being arranged in the support construction exterior side wall of logistics air flow controller.Side The top and bottom of portion's air flow regulator and central gas stream regulating device are separately set from outside to inside in a circumferential direction There is multi-turn to wear stomata.After adding edge air flow regulator and central gas stream regulating device, edge cooling wind and center can be made Cooling wind can make air-flow more uniform to intermediate flow, it is therefore prevented that since air-flow is by the way that material path is short or edge Cooling air-flow caused by effect flows out too much from edge or center, and the intermediate material cooling wind so as to caused by is few and cools down not Good effect.
Preferably, which further includes multiple temperature elements, and position is located on the side wall of air inlet discharge device, And it extend into the inside of air inlet discharge device.Preferably, temperature element can be thermocouple temperature sensor.
Feed bin is a cylindrical or rectangular barrel-like structure, for buffering the heat sinter for holding conveyer transport and coming, material Orlop portion is fixedly connected on tower top.Material envelope cloth tube is a cylindrical or rectangular barrel-like structure, positioned at bin bottom, the upper end It being fixedly connected with bin bottom, lower end is stretched into below tower top, inside tower body, wherein, sinter can be from the bottom of feed bin It enters under the effect of gravity inside material envelope cloth tube, and can be free from material envelope cloth tube lower openings under gravity Outflow.Tower wall is a cylindrical or rectangular barrel-like structure, and the upper end is fixedly connected with tower top, and the weight of tower top is undertaken on tower wall one Week.Bottom of towe is located at tower wall lower end, is fixed with basis.Generally, hot air draft mouth is located at tower wall top or tower top, with tower wall or tower top It is fixedly connected, and with connect inside tower body, hot wind is across the charge level by bed of material top after the bed of material, into bottom of towe and tower wall shape Into tower body upper end non-material area, then using hot air draft mouth discharge;Preferably enter follow-up afterheat generating system.
Preferably, which also has self feed back discharge regulatory function.The sintering of corresponding region is detected by temperature element Ore deposit temperature after the sinter temperature of some circumferential position of detection reaches cooling effect, just normally opens region correspondence Air inlet discharge device below discharge apparatus, normal discharge is carried out, conversely, when the sinter in the region being allowed to cool down one section again Between, after sinter temperature reaches cooling effect, then carry out normal discharge.
Generally, the height for the tower body being made of tower top, tower wall and bottom of towe is usually 4-30 meters, preferably 5-25 meters, more preferably It is 6-20 meters, 8-15 meters further preferred.The overall diameter of tower body is generally 8-30 meters, preferably 9-27 meters, preferably 10-25 meters, preferably It is 11-22 meters, 12-20 meters more preferable.
