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 technique, for heat of cooling sintering deposit.Chassis is one of vitals of sintering circular-cooler, for carrying heat sinter.Conventional sintering central cooler does not all have quantity not etc. according to the difference of scale, several chassis that profile is consistent, these chassis are that cross section is the flat column structure of isosceles trapezoid, be arranged in order the structure that forms an approximate annulus along central cooler circumferencial direction, each chassis is connected with triangular beam corresponding on revolving body by ball pivot, 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, bottom passes into normal temperature air, cold air carries out heat exchange by air vent and hot-bulb nodulizing and is taken away heat and reached the object of cooling sintering deposit by high-temp waste gas.When central cooler is normally produced, its revolving body drags chassis by the ball pivot on triangular beam and turns round around the central cooler centre of gyration along circular orbit, cooling section chassis level run, unloading part chassis is taking ball pivot as suspension centre, wheel moves along Orbit unloaded skip, make chassis entirety downward-sloping angled with horizontal plane, on chassis, cooled sintering deposit is dumped in dump skip, chassis after discharging continues the curve along bend under the traction of ball pivot and moves ahead, make chassis sub-level again, continue to accept heat sinter and complete next cool cycles.In sintering deposit cooling procedure, owing to being subject to the steel plate above structural limitations triangular beam there is no air vent, the heat sinter on its top is relative less with the chance that cooling air carries out direct heat exchange, thereby can affect the cooling effect of this part sintering deposit, because the one-to-one relationship of triangular beam and chassis, several this impacts progressively cumulative cooling effect that will make whole central cooler reduce.In addition, the chassis of this kind of structure is because trolley body is in cooling section level, and unloading part tilts, and the sealing of central cooler can not be continuous, makes thus the overall sealing effectiveness of central cooler undesirable, and 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 like this increase of energy consumption, also can exert an influence to the economic benefit of enterprise.Moreover the volume of triangular beam itself has also tied up certain appearance material volume, reduce to a certain extent the production capacity of equipment.
