Abstract
A slag feeding sealing device mainly resolves the problem of slag leakage between a feeding chamber and a cylinder when a cold slag discharger is in operation, and comprises a slag feeding assembly connected with the cylinder, a fixing ring is arranged at a connecting end of the cylinder with the slag feeding assembly and fixedly connected with a moving seal ring, one side of the moving seal ring matched with the fixing ring is a plane, and an annular groove is arranged on the other side of the moving seal ring. A fixed seal ring and a pressure cover are sequentially arranged at the connecting end of the slag feeding assembly with the cylinder, one side of the fixed seal ring is provided with a protrusion matched with the annular groove on the moving seal ring, the other side of the fixed seal ring is a plane, and the pressure cover and the moving seal ring are fixedly connected through a threaded connector. By means of a special design of the moving seal ring and the fixed seal ring which are mutually matched, slag leakage due to planar fit is avoided, and utilization of the slag feeding sealing device is facilitated.
Description
Technical field
The utility model relates to a kind of seal arrangement that is used for cold slag slagging machine, specifically a kind of slag input seal arrangement.
Background technique
Boiler is used widely in a lot of industries as a kind of energy conversion, and in order can the cinder that boiler is discharged to be lowered the temperature timely and to be transported, cold slag slagging machine is accompanied by boiler becomes equipment important in the commercial production.The place's ubiquity of being association of activity and inertia of traditional cold slag slagging machine rotary barrel and static feed space leaks the slag phenomenon; The slag temperature at feed space place is very high; Leaking slag brings very big hidden danger not only for site environment and production; Also the use to cold slag slagging machine brings adverse influence, needs a kind of seal arrangement to avoid leak slag phenomenon in actual use.
The model utility content
The purpose of the utility model is to provide a kind of slag input seal arrangement, and the sealing device can be avoided the leakage slag phenomenon of feed space and cylindrical shell junction effectively.
The technological scheme that its technical problem of the utility model solution is taked is: the slag input seal arrangement; Comprise the slag input assembly that is connected with cylindrical shell; It is characterized in that the connecting end of said cylindrical shell and slag input assembly is provided with a retaining ring, retaining ring is fixedly connected with a rotary packing ring; The side that said rotary packing ring cooperates with retaining ring is the plane, and the another side is provided with the groove of ring-type; Connecting end at itself and cylindrical shell on the slag input assembly is provided with stationary seal ring and gland successively, on the said stationary seal ring side be provided with rotary packing ring on the convexity that matches of annular recess, opposite side is the plane; Be fixedly connected through threaded connector between said gland and the rotary packing ring.
Adopt between said retaining ring and the said cylindrical shell and be welded to connect.
Compared with prior art; The utlity model has following outstanding beneficial effect: the mode that traditional plane is cooperated with the plane changes rotary packing ring and the mutual interlock of stationary seal ring into; Because fitting surface is provided with the groove and the convexity of mutual interlock, stops that effectively slag spills from fitting surface, has avoided leakage slag phenomenon; Thereby eliminated because of leaking the various hidden danger that slag brings, guaranteed the working life of cold slag slagging machine and the safety of production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 retaining ring, 2 rotary packing rings, 3 stationary seal rings, 4 glands, 5 slag input assemblies, 6 cylindrical shells.
Embodiment
As shown in Figure 1, the slag input seal arrangement comprises the slag input assembly 5 that is connected with cylindrical shell 6, and said cylindrical shell 6 is provided with a retaining ring 1 with the connecting end of slag input assembly 5, and retaining ring 1 is fixedly connected with a rotary packing ring 2; The side that said rotary packing ring 2 cooperates with retaining ring 1 is the plane, and the another side is provided with the groove of ring-type; Connecting end at itself and cylindrical shell 6 on the slag input assembly 5 is provided with stationary seal ring 3 and gland 4 successively, on the said stationary seal ring 3 side be provided with rotary packing ring 2 on the convexity that matches of annular recess, opposite side is the plane; Be fixedly connected through threaded connector between said gland 4 and the rotary packing ring 2.
Adopt between said retaining ring 1 and the said cylindrical shell 6 and be welded to connect.Welding can make its firm and reliable connection, beautiful shape.
During operation; Cylindrical shell 6 rotations; Driving retaining ring 1, rotary packing ring 2 and gland 4 rotates together; This moment, stationary seal ring 3 and the slag input assembly 5 between rotary packing ring 2 and gland 4 was actionless, and cylindrical shell 6 is rotary packing ring 2 and the occlusal surface that stationary seal ring 3 constitutes with the cooperation place of slag input assembly 5, has avoided the plane to cooperate the leakage slag phenomenon that causes.
Claims (2)
1. the slag input seal arrangement comprises the slag input assembly that is connected with cylindrical shell, it is characterized in that, the connecting end of said cylindrical shell and slag input assembly is provided with a retaining ring, and retaining ring is fixedly connected with a rotary packing ring; The side that said rotary packing ring cooperates with retaining ring is the plane, and the another side is provided with the groove of ring-type; Connecting end at itself and cylindrical shell on the slag input assembly is provided with stationary seal ring and gland successively, on the said stationary seal ring side be provided with rotary packing ring on the convexity that matches of annular recess, opposite side is the plane; Be fixedly connected through threaded connector between said gland and the rotary packing ring.
