a decoking tool

Abstract

The invention relates to the field of removal tools, and discloses a decoking tool. The decoking tool comprises a handheld part (1), a coke removal rod (2) and a connecting part connected with the handheld part (1) and the coke removal rod (2). The connecting part comprises elastic connecting pieces and fixed pieces. The elastic connecting pieces are elastically connected with the handheld part (1) and the coke removal rod (2). The fixed pieces are fixedly connected between the handheld part (1) and the coke removal rod (2). By means of the technical scheme, when large coke blocks fall on the end of the coke removal rod, the fixed pieces are broken, and the coke removal rod moves in the falling direction of the large coke blocks; and at this moment, due to the fact that the elastic connecting pieces are arranged between the handheld part and the coke removal rod, the elastic connecting pieces can be bent along with the coke removal rod, the handheld part cannot be upwarped, and therefore the personal safety of workers can be guaranteed.

Description

technical field [0001] The invention relates to a removal tool, in particular to a decoking tool for beating the coke blocks coked on the inner wall of a boiler furnace to remove the coke blocks. Background technique [0002] In coal-fired boilers in thermal power plants, when the coal contains a lot of ash, coking will occur on the inner wall of the boiler furnace, especially at the burners of each layer. If the coke is not removed in time, the boiler will deteriorate. In severe cases, the furnace needs to be shut down for decoking. [0003] In the past, coking rods were used for decoking operations, and the coking rods were rod-shaped members made of steel. The process of decoking operation is: the furnace of the boiler is generally a cuboid, and a plurality of burners are arranged vertically on the four corners of the cuboid (that is to say, a plurality of burners are arranged at different heights, generally in a The upper, middle and lower burners are set on the corner...

AI Technical Summary

Problems solved by technology

However, when the coke block is knocked upwards at the burner below, if the large coke block falls and hits the second end of the coke-beating stick, the first end of the coke-beating stick will be tilted upwards, and the raised coke stick will be tilted upwards. The scorching stick will cause damage to the face and jaw of the staff. At the same time, the scorching stick will fall off from the staff's hand and fall into the furnace, causing the slag crusher to get stuck, seriously affecting the normal work in the furnace
