Fig. 2 is the structural representation of the dreg scraper in the utility model;
Fig. 3 is the side-view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of rotary hearth furnace slag discharging device, it is characterized in that, described device comprises: material guide groove 6, discharge groove 2, drag for slag band 4 and drive the driving arrangement 1 dragging for slag band 4 cycle operation, be enclosed casing 8 from material guide groove 6 to discharge groove 2, describedly drag for slag band 4 and described driving arrangement 1 is arranged in described casing, described casing comprises horizontal section and tilting section, described horizontal section cross rotary hearth furnace inner and outer ring and by the inner and outer ring water sealed tank UNICOM of described material guide groove 6 with rotary hearth furnace, be provided with between described material guide groove 6 and described horizontal section and cut off gate valve 7, cut off gate valve 7 and can cut off connecting of water sealed tank and horizontal section when fault, the inclined slope of described tilting section is called draining slope 3, described discharge groove is positioned at below described draining slope 3, cycle operation drag for slag band 4 by draining slope 3 on the successive floor mop of slag charge received, described draining slope 3 is 58 degree with the angle of described horizontal section, 58 degree of angles can make in every kilogram of slag charge containing 5.2g water. it has been generally acknowledged that the larger draining effect of the gradient is better, through experiment test, when angle is greater than 58 degree, there will be the trend of draining deleterious, in every kilogram of slag charge, water content increases, be 6.0 when 59 degree, be 6.2 when 60 degree, continuation along with angle increases the water content of every kilogram of slag charge more than 6 grams.
