Abstract

The invention relates to the technical field of boiler grates, in particular to a sealing structure for a boiler reciprocating grate. The sealing structure can discharge ash, reduce the number of times of shutdown and ensure continuous operation of a boiler during operation and comprises the reciprocating grate, side sealing plates are arranged on the left side and the right side of the reciprocating grate, a front sealing plate is arranged below the front end of the reciprocating grate, a manhole door is arranged at the side part of the front sealing plate, and a manhole door plate is arranged at the manhole door. The sealing structure is characterized in that a movable ash discharging door plate is arranged at the bottom of the front sealing plate, the movable ash discharging door plateis connected with one end of a transmission shaft, the other end of the transmission shaft penetrates through a front wall and a sealing housing fixed on the front wall and is provided with a rotatinghandle, a positioning sleeve is installed on the outer wall of the sealing housing, internal threads are arranged in the positioning sleeve, a through hole is formed in the rotating handle, a bolt matched with the positioning sleeve is installed at the through hole, and end sealing plates are not arranged at the front ends and the rear ends of the side sealing plates.

Description

technical field [0001] The invention relates to the technical field of boiler grates, in particular to a sealing structure for boiler reciprocating grates. Background technique [0002] At present, the sealing structure of the front end of the reciprocating grate of the boiler adopts a structure in which the manhole door and the side seal are not connected, such as figure 1 As shown, the manhole door is used as ash release for the ash leakage in the front seal when the furnace is shut down. In this way, if the ash is not released for a long time, due to the reciprocating movement of the grate during operation, the front seal will leak ash and the grate will be firmly stuck, causing the boiler to shut down. . Contents of the invention [0003] In order to solve the problem that existing boilers need to be frequently shut down to release ash, which affects the operating efficiency of the boiler, the present invention provides a sealing structure for the reciprocating grate...
