Abstract

The utility model relates to a component, or an accessory, or a sintering member, or a special open or uncovered sintering device of a similar device, or other heat treatment device with the similar structure for an annular cable sintering machine. Rectangular lower right angle steel channel box bodies of a secondary oil immersed sealing device are arranged outside supporting racks of fixed slide ways on both sides of a machine body of a sintering machine, and both sides of the lower bottom of a sintering trolley are provided with right angle sliver-shaped upper angle steel channel slide cover plates. The utility model avoids air leakage on both sides between the slide plates of the trolley and the fixed slide way, and the secondary sealing on both sides obtains optimum effect. So that the utility model enhances the quality and the production capacity of sintered ores, and lowers the cost of sintered ores, etc.

Description

Sintering machine fuselage both sides secondary oil is invaded seal arrangement

The utility model relates to endless-strand sintering machine component, annex or sintering or distinctive device open type of similar devices or uncovered agglomerating plant; The heat treatment installation of other similar structure, particularly sintering machine fuselage both sides secondary oil is invaded seal arrangement.

Present metallurgy sintered system adopts down draft sintering technology fully, and the rated power of induced draft fan is from 500-6300KW, and the import air quantity of induced draft fan is from 1600-16000M ³/ min, the sealing of sintering machine fuselage bogie slide plate and ground way is to adopt the sealing of elasticity bogie slide plate oil lubrication sealing means substantially, ubiquity because the long-term periodical repair of using, assemblage gap, bogie slide plate and ground way wearing clearance are bigger, helical spring is insensitive, the oil lubrication sealing is relatively poor, thereby cause the sealing of bogie slide plate and ground way to leak out comparatively serious, the air leak rate of air curtain of sintering machine is generally 50-58%, have up to more than 60%, there is the wind more than 40% not pass through sinter bed, air leak rate of air curtain between bogie slide plate and the ground way accounts for more than 40%-60%, make induced draft fan do a large amount of idle works, cause and do not reach required sintering temperature, so influenced the intensity of sintering deposit, the quality and the output of sintering deposit have been reduced, the sintering temperature low power consuming is bigger, the unstable insufficient black smoke of fuel combustion is bigger, it is comparatively serious to have wasted a large amount of electric power resources and energy consumption, the cost of sintering deposit is higher, heat-energy losses is more, the heat energy utilization rate is lower, improve burning sintering temperature shortcomings such as comparatively difficulty is particularly outstanding especially, in order to overcome above-mentioned existing deficiency, the utility model has designed sintering machine fuselage both sides secondary oil and has invaded seal arrangement.

The purpose of this utility model provides avoids between bogie slide plate and the ground way both sides to leak out, and secondary seal gap, both sides is little, good seal, reduce the air leak rate of air curtain of sintering machine, improve sintering temperature, improve the quality and the output of sintering deposit, increase the intensity of sintering deposit, fuel combustion is fully stable, save the energy, reduce the sintering deposit cost, heat-energy losses is few, heat energy utilization rate height, sintering machine fuselage both sides secondary oil simple in structure is invaded seal arrangement.

The utility model is achieved in that in the outside of sintering machine fuselage both sides ground way supporting frame the secondary oil that is rectangle being installed invades sealed lower portion Steel Square tank body, the bottom side span perforation of invading sealed lower portion Steel Square tank body at secondary oil is equipped with oil filler pipe in the sealing, sintering pallet go to the bottom both sides fixedly the inside upper part of the outside of channel-section steel card spring slide plate and sintering pallet wheel hub right angle, the top steel tank slippery cover plate of rectangular long strip is installed, right angle, top steel tank slippery cover plate lower inside surface and secondary oil are invaded sealed lower portion Steel Square tank body upper outside face and are slipped mutually and contact.

The utility model has avoided the both sides between bogie slide plate and the ground way to leak out, the both sides secondary seal has reached optimum efficiency, reduced the air leak rate of air curtain of sintering machine, avoided induced draft fan to do a large amount of idle works, cause the sintering temperature that reaches required, the quality and the output of sintering deposit have been improved greatly, increased the intensity of sintering deposit, the sintering temperature highly energy-consuming is less, and it is less that abundant black smoke is stablized in fuel combustion, avoided wasting the consumption of a large amount of electric power resource and the energy, saved the energy, greatly reduced the cost of sintering deposit, heat-energy losses is less, the heat energy utilization rate is higher, it is obvious to improve the burning sintering temperature, and effective working efficiency of sintering machine is greatly improved, and economic benefit and social benefit effect are particularly outstanding especially significantly considerable, and volume simple and compact for structure is little, be easy to make and install, the maintenance maintenance is easy, change flexibly and fast, time saving and energy saving, be easy to apply advantage such as with low cost.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

To be described in further detail concrete structure of the present utility model and embodiment below in conjunction with accompanying drawing.

Referring to accompanying drawing 1, Fig. 2, Fig. 3, shown in Figure 4: as in the outside of sintering machine fuselage 1 both sides ground way 5 supporting frames 6 the secondary oil that is rectangle to be installed and to invade sealed lower portion Steel Square tank body 8, the bottom side span perforation of invading sealed lower portion Steel Square tank body 8 at secondary oil is equipped with oil filler pipe 7 in the sealing, sintering pallet 2 go to the bottom both sides fixedly the inside upper part of the outside of channel-section steel card 10 springs 3 slide plates 4 and sintering pallet 2 wheels 11 wheel shafts 12 right angle, the top steel tank slippery cover plate 9 of rectangular long strip is installed, right angle, top steel tank slippery cover plate 9 lower inside surface and secondary oil are invaded sealed lower portion Steel Square tank body 8 upper outside faces and are slipped mutually and contact.
