Description
Technical field
The utility model relates to the central cooler technology of metallurgical briquetting, sintering art, particularly the seal arrangement between a kind of central cooler slewing frame and bellows.
Background technique
Between the circular cooler trolley slewing frame of China's metallurgical briquetting, sintering art and bellows, seal, what adopt at present is following two kinds of structures: the 1) contact seal of the flexible member such as rubber or composite material and rigid pipe composition; 2) hydraulic seal forming between the chassis sealing plate in insertion ring-type liquid bath and bellows.
Flexible sealing material has elasticity contact form and seals.Problem: because rubber material cracky, heat resistance deficiency, often initial stage sealing effect still can, long-time running is leaked out seriously, up to 30%～50%; Make that apparatus cools effect is undesirable, environment is poor, UTILIZATION OF VESIDUAL HEAT IN efficiency is low.Composite seal intensity and wear resistance are all better than rubber, but leak out in order to prevent, hermetic resistance is larger, and plant capacity consumption increases.
Liquid sealing, due to good sealing effect, highlights its sealing advantage.Cooling effect and the environment of equipment are stronger than contact seal.Deficiency is to have increased a set of plumbing and sewage disposal system, regularly removes in addition the wet silt material being deposited in tank, is subject to spatial constraints, and operation and maintenance are all more difficult than contact seal.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the seal arrangement between central cooler slewing frame and the bellows of good sealing effect.
The utility model is to realize like this.
According to the seal arrangement between central cooler slewing frame of the present utility model and bellows, comprise central cooler frame, the internal support roller being connected with central cooler upper rack and external support roller, the interior slewing frame and the outer slewing frame that by internal support roller and external support roller, support, the bellows that are connected with central cooler frame lower, be arranged on the seal arrangement between interior slewing frame and outer slewing frame and bellows, it is characterized in that described seal arrangement is interior seal groove and the external sealed groove of U shape by two cross sections that are separately positioned in central cooler frame, be arranged on the particle media in interior seal groove and external sealed groove, one end is fixedly connected with outer slewing frame with interior slewing frame respectively, interior annular sealing plate and outer ring-like sealing plate institute that the other end inserts respectively in the particle media of interior seal groove and external sealed groove form.
Described interior seal groove and the top of external sealed groove are that vertical shape structure or both sides are evagination concave inward structure.
Described particle media is that granularity is the ripe ball of haydite, glass bead, sintering or the sand grains that granularity is less than 6mm.
The degree of depth of described particle media in interior seal groove and external sealed groove is more than 500mm.
The utility model has the advantages that: because the utility model has adopted the seal arrangement of said structure, effectively improve the sealing effect between circular cooler trolley slewing frame and bellows, make that sealing configuration is more simple, good sealing effect.When the medium of selecting and its degree of depth at seal groove suitable, just can in medium, not occur pipeline and fluidization phenomenon reaching desirable sealing effect.The bulk cargo and the medium that fall into individually seal groove mix, and do not affect the work of medium.During final replacing medium, remove together, exempted the workload of removing bulk cargo in seal groove.

Fig. 1 is structure section schematic diagram of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1;
Fig. 3 is another embodiment's of the grooved that prevents that sealing medium from overflowing schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the seal arrangement between central cooler slewing frame of the present utility model and bellows,
According to the seal arrangement between central cooler slewing frame of the present utility model and bellows, comprise central cooler frame 11, the internal support roller 4 and the external support roller 10 that are connected with central cooler frame 11 tops, the interior slewing frame 1 supporting by internal support roller 4 and external support roller 10 and outer slewing frame 7, the bellows 5 that are connected with central cooler frame 11 bottoms, be arranged on the seal arrangement between interior slewing frame 1 and outer slewing frame 7 and bellows, it is characterized in that described seal arrangement is interior seal groove 3 and the external sealed groove 9 of U shape by two cross sections that are separately positioned in central cooler frame 11, be arranged on the particle media 6 of interior seal groove 3 and external sealed groove interior 9, one end is fixedly connected with outer slewing frame 7 with interior slewing frame 1 respectively, interior annular sealing plate 4 and outer ring-like sealing plate 8 that the other end inserts respectively in the particle media of interior seal groove 3 and external sealed groove 9 form.
This sealing is that the connected portion in the middle of the interior slewing frame 1 of central cooler and the bottom of outer slewing frame 7 and bellows arranges respectively interior seal groove 3 and external sealed groove 9, in groove, fill the granular sealing medium 6 of certain depth, and the interior annular sealing plate 2 and the outer ring-like sealing plate 8 that are fixed on slewing frame insert in the granular sealing medium 6 of seal groove separately, in order to realize the chassis of motion, return the sealing between framework and static bellows.
As shown in Figure 3, the top of interior seal groove 3 described in the utility model and external sealed groove 9 is that vertical shape structure or both sides are evagination concave inward structure.If seal groove degree of depth spatial margin is enough, can make straight trough; If seal groove degree of depth spatial margin is limited, both sides can be made in seal groove top is evagination concave inward structure, in case particle media, when sealing plate is offset, rises and overflows outside groove.
Described particle media 6 for granularity be the ripe ball of haydite, glass bead, sintering or the sand grains that granularity is less than 6mm.
The utility model adopts particle media 6 to realize sealing, and the resistance that the granule medium 6 getting up when accumulation forms is sufficiently more than the resistance of the bed of material, and most cooling airs just pass from the bed of material, can meet the requirement of process for cooling completely.Because particle media good fluidity, surface friction drag are little, thereby become the first-selection of sealing medium.
The degree of depth of described particle media 6 in interior seal groove 3 and external sealed groove 9 is more than 500mm.In it, the width of seal groove 3 and external sealed groove 9 is mainly considered the off-set wave momentum of sealing plate radial motion.
