Description
Technical field
The invention belongs to and be used for the metallurgical mine industry is carried out cooling operations to the sintered balls nodulizing rotary forced-air cooler.
Background technology
Rotary forced-air cooler is one of equipment of sintered balls nodulizing cooling operations.No. 00224627.9 utility model patent document of China discloses a kind of novel rotary forced-air cooler, and the outstanding problem that this eedle exists traditional drum wind central cooler has carried out improving preferably, makes the rotary forced-air cooler technology reach a new level.Novel rotary forced-air cooler comprises double-deck chassis, parts such as air channel, supply air system go in ring.Novel rotary forced-air cooler finds to also have some unsatisfactory places through operation after a while:
One, the chassis backbar is that cross section is leg-of-mutton beam, and three limits of beam all are blind plates, only plays the effect of supporting chassis.During work, all filled mineral aggregate on trolley grating plate and the three cantilevered corner beam inclined-planes, cold wind is forced to blast the bed of material down from trolley grating plate and is carried out heat exchange, because wind always can be along the resistance minimum, and the both sides process of zone three cantilevered corner beams that the approach distance is the shortest, after carrying out heat exchange with mineral aggregate, enter atmosphere from bed of material end face, because three cantilevered corner beams are blind plates, the upper area on perspective plane, three cantilevered corner beam bases just has only less air quantity to enter, even forming the cooling dead band, red sometimes material all can not get cooling.Cold wind is higher through the regional wind speed directly over the grate plate, and the dust of being heaved is also bigger, and is also very big to the surrounding enviroment contamination by dust.
Two, the joint portion of chassis and ducting system is the air channel sealing plate, has ventilating opening above, and the wind of ducting system just can enter chassis from ventilating opening.After the central cooler cooling operations, chassis enters discharge zone, the beginning discharging.At this moment annular passage is sealed dams, and the sealing plate ventilating opening stops air intake.Chassis slowly tilts along the discharging bend, and the bed of material is discharged into the discharge chute from slowly landing downwards of trolley grating plate.When chassis falls to grate plate, during through the sealing plate ventilating opening, the material on the grate plate just can be fallen in the ventilating opening pipe from the inboard, air port, slowly accumulate, and progressively press in the wind channel tube, at last the ventilation mouth of pipe is stopped up, make the sealing plate of ventilation partially or completely lose draught effect.
Three, static seal device is the contact unit static sealing apparatus, it is to seal as a unit seal area with every single chassis, utilize the special-shaped beam of the front and back grate plate function that supports chassis, and the lower floor plane that inside and outside side seal plate and trolley body are set between special-shaped beam is formed, central cooler has several chassis just to set up the plurality of units seal area, forms a contact unit static sealing apparatus system that is made up of a plurality of unit seal area on the whole.During cooling operations, cold wind enters chassis from seal area inboard, unit, enters the bed of material through the trolley body grate plate again, after heat exchange, enters atmosphere from charge level.Wind is after entering chassis, because unit static sealing apparatus all defines the altitude range of a sealing at the chassis four direction, only accomplishes to make special-shaped soffit plate to contact with chassis lower floor surface plate in monolateral position of special-shaped beam and compresses.All the other of special-shaped beam on one side and three parts such as medial and lateral sealing plate all keep certain interval with chassis lower floor surface plate, therefore, all there is the sealed against leakage problem in the four direction between the special-shaped beam of layer plane and inner seal plate and outside sealing plate and front and back grate plate function under the trolley body.And in cooling procedure, powder on the chassis can scatter on lower floor's flat board of chassis from the grate plate slit every now and then, especially the cooling stage in early stage after chassis when filling with substance and charging, the material that scatters is a high temperature, still 700～800 ℃ red ore deposit, these high temperature mineral aggregates also can be by wind around flat board, directly be adjacent to caulking gum spare, rubber parts is burnt, when the rubber parts scaling loss is serious, sealing is just destroyed, leaks out and will take place.
Four, go in ring the air channel when air-supply, the water in its water seal can produce vibration or resonance because of the influence of wind in the air channel, especially in fan starting and stopping process, during air generation surge, can cause water attack or judder.If vibration evokes spray, will be brought into chassis by the high velocity air in the air channel, perhaps because vibration, when liquid level is lower than the side plate bottom, wind will climb over the side plate bottom, is being with water outwards to spray and leakage from the liquid bath both sides, and operation produces harmful or destructive influences to equipment.
The present invention has further improved the sealing property of equipment by above improvement, has reduced energy consumption, has reduced pollution.
