Abstract
The utility model relates to a furnace gas circulating device for a roasting furnace. The furnace gas circulating device comprises a roasting furnace body, a centrifugal circulating fan and a heater, wherein the centrifugal circulating fan is arranged on one side of the roasting furnace body, an air pipe is arranged on the side of the roasting furnace; and the centrifugal circulating fan is fixedly connected with the roasting furnace by a connecting flange. The furnace gas circulating device has the advantages that the manufacturing cost is greatly reduced, the manufacturing difficulty is greatly lightened, the later maintenance is convenient, and the maintenance cost is reduced.
Description
Technical field:
The utility model relates to a kind of EGR, especially relates to a kind of roaster furnace atmosphere circulation device.
Background technology:
In roaster, be to guarantee the uniformity of roaster furnace gas, all adopt the endless form of furnace roof double suction fan, wind direction is from top to bottom in this endless form stove, through guipure, is sucked by the inlet scoop, both sides from double suction fan, the air channel of furnace side.This mode is owing to adopted double suction fan; Body of heater must be designed to the upper and lower covers formula, when blower fan is installed and keep in repair, all will open furnace upper cover, removes the airduct on the furnace roof; And the axle and the bearing life of blower fan are not long, have all increased cost and trouble for like this manufacturing cost and maintenance.
Summary of the invention:
The utility model technical problem to be solved provides a kind of manufacturing and the low roaster furnace atmosphere circulation device of maintenance cost.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: this roaster furnace atmosphere circulation device; Comprise roaster body, centrifugal circulating fan and heater; Said centrifugal circulating fan is arranged on roaster body of heater one side, and this furnace side also is provided with airduct, is fixedly connected through adpting flange between said centrifugal circulating fan and the roaster.
Compared with prior art, the usefulness of the utility model is: this roaster furnace atmosphere circulation device has alleviated manufacturing cost and manufacture difficulty greatly, has made things convenient for later maintenance, has alleviated maintenance cost.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structural representation.
Among the figure: 1, roaster; 2, airduct; 3, adpting flange; 4, centrifugal circulating fan; 5, heater.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
A kind of roaster furnace atmosphere circulation device shown in Figure 1 comprises roaster 1 body, centrifugal circulating fan 4 and heater 5, and said centrifugal circulating fan 4 is arranged on roaster 1 body of heater one side, and this furnace side also is provided with airduct 2; Be fixedly connected through adpting flange 3 between said centrifugal circulating fan 4 and the roaster 1; Be connected with roaster 1 through adpting flange 3, the adpting flange 3 that only need dismantle between centrifugal circulating fan 4 and the roaster 1 when installing and keeping in repair centrifugal circulating fan 4 gets final product.
Wind is sucked by centrifugal circulating fan 4 inlet scoops from top to bottom through workpiece in this roaster furnace atmosphere circulation device stove, through centrifugal circulating fan 4, again by passing through heater 5 again to burner hearth by a crosswind road; Alleviate manufacturing cost and manufacture difficulty greatly, made things convenient for later maintenance, alleviated maintenance cost.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
