Abstract
The invention belongs to the technical field of metallurgical equipment and particularly relates to a sintering annular cooler pallet which comprises a set of separated type pallets which are sequentially arrayed in the circumferential direction of an annular cooler. The sintering annular cooler pallet is characterized in that each separated type pallet comprises a fan-shaped pallet body, a panel and a set of grates, wherein the fan-shaped pallet body is connected with a revolving frame of the annular cooler through two eccentric gudgeons,, the panel is arranged on a fan-shaped pallet body frame and the set of grates are connected with the panel through a set of pressing plates. According to the sintering annular cooler pallet, the structural defects of an original sintering annular cooler pallet are overcome. The pallet bodies are fan-shaped pallet bodies with eccentric shafts. An original triangle beam structure is cancelled and the ventilation area of the annular cooler is increased so that a sinter can be cooled more fully and sealing can be easier to achieve. In addition, the grates of the pallet are assembly type blind window grates. Therefore, when the pallet grates are damaged, the pallet does not need to be replaced integrally. Manpower and material resources are saved, and cost is saved.
Description
Technical field
The invention belongs to technical field of metallurgical equipment, especially relate to a kind of sintering ring cold machine trolley.
Background technology
Sintering circular-cooler is one of visual plant of SINTERING PRODUCTION technology, is used for heat of cooling sintering deposit.Chassis is one of vitals of sintering circular-cooler, is used for the carrying heat sinter.The conventional sintering central cooler all has quantity according to the difference of scale not to be waited, several chassis of profile unanimity, these chassis are that the cross section is the flat column structure of isosceles trapezoid, be arranged in order the structure that forms an approximate annulus along the central cooler circumferencial direction, each chassis links to each other by three corresponding on ball pivot and revolving body cantilevered corner beams, and along with revolving body rotates around the central cooler centre of gyration together, chassis upper surface carrying hot-bulb nodulizing also has the air vent that series of rules is arranged, the bottom feeds normal temperature air, and cold air carries out heat exchange and takes away the purpose that heat reaches the cooling sintering deposit by high-temp waste gas by air vent and hot-bulb nodulizing.During the central cooler ordinary production, its revolving body drags chassis by the ball pivot on three cantilevered corner beams and turns round around the central cooler centre of gyration along circular orbit, cooling section chassis level run, the unloading part chassis is suspension centre with the ball pivot, wheel is along the discharging flexible bend running, make chassis whole downward-sloping angled with horizontal plane, cooled sintering deposit is dumped in the dump skip on the chassis, chassis continuation curve along bend under the traction of ball pivot after the discharging moves ahead, make and continue chassis sub-level again to accept heat sinter and finish next cool cycles.In the sintering deposit cooling procedure, owing to be subjected to the steel plate above structural limitations three cantilevered corner beams not have air vent, the heat sinter on its top is relative less with the chance that cooling air carries out the direct heat exchange, thereby can influence the cooling effect of this part sintering deposit, the cooling effect that will make whole central cooler reduces because the one-to-one relationship of three cantilevered corner beams and chassis, several this influences progressively add up.In addition, the chassis of this kind structure since trolley body in the cooling section level, unloading part tilts, the sealing of central cooler can not be continuous, makes that thus the overall sealing effectiveness of central cooler is undesirable, air leak rate of air curtain is bigger than normal.Want the cooling effect that reaches desirable, just need to increase the air quantity of cooling blower, certainly will cause the increase of energy consumption like this, also can exert an influence to economic benefit of enterprises.Moreover the volume of three cantilevered corner beams itself has also tied up certain appearance material volume, has reduced the production capacity of equipment to a certain extent.
