Description
Technical Field
The utility model relates to a cold sediment ware technical field specifically is a cold sediment ware entry seal structure.
Background
The structure of the inlet of the slag cooler of the existing circulating fluidized bed boiler is shown in figure 1, only one cover plate 3 is arranged at the inlet of a slag discharging pipe 1 and the inlet of a slag cooler 2 for sealing, and a certain gap is formed between the cover plate 3 and the slag discharging pipe 1 and is set for the requirement of expansion of the slag discharging pipe 1. The slag discharging pipe 1 of the boiler can move downwards due to the expansion of the boiler during the operation of the boiler, the inside of the slag discharging pipe 1 is in positive pressure, the temperature of the discharged high-temperature ash exceeds 900 ℃, and a part of the discharged high-temperature ash is fine ash, so that the gap is easily sprayed with fire and ash outwards.
Disclosure of Invention
In order to solve the problem that the clearance of the inlet of the existing slag cooler is easy to be sprayed with fire and ash, the utility model provides a sealing structure for the inlet of the slag cooler, which can effectively realize the sealing of the clearance.
The technical scheme is as follows: the utility model provides a cold sediment ware entry seal structure, its includes cold sediment ware and scum pipe, the entrance of cold sediment ware is provided with into the sediment fill, scum pipe bottom stretches into in advancing the sediment fill, the opening part of advancing the sediment fill is provided with the round apron, the apron inboard with leave the clearance between the scum pipe outer wall, its characterized in that, be provided with round high temperature resistant filler on the apron, high temperature resistant filler outside is provided with the seal box, the seal box upper end with scum pipe outer wall welding, the seal box lower extreme is located the apron below and with it does not weld to advance between the scum pipe outer wall.
Adopt the utility model discloses afterwards, increased seal box and high temperature resistant filler, constituted labyrinth seal structure with original apron together, thin ash or flame can not outwards spout in the clearance, the effectual clearance department of having solved sealed not tight problem.
Drawings
FIG. 1 is a schematic diagram of a prior art structure;
fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
See fig. 2, a cold sediment ware entry seal structure, it includes cold sediment ware 2 and scum pipe 1, the entrance of cold sediment ware 2 is provided with into sediment fill 4, scum pipe 1 bottom stretches into in the sediment fill 4, the opening part of advancing sediment fill 4 is provided with round apron 3, leave the clearance between 3 inboard and the scum pipe 1 outer wall of apron, be provided with round high temperature resistant filler 5 on the apron 3, high temperature resistant filler 5 outside is provided with seal box 6, seal box 6 upper end and scum pipe outer wall welding, seal box 6 lower extreme be located apron 3 below and with advance the sediment fill 4 outer walls between not welded, the seal box can follow the removal when the scum pipe takes place to expand downwards, can not play the restriction.
The ash and slag discharged from the slag discharge pipe 1 can be blocked by the high-temperature-resistant filler 5 and the sealing box 6 when reaching the gap, and cannot be sprayed out, so that a good sealing effect is achieved.
