Boiler fire tube cleaning device

Abstract

The invention relates to a boiler fire tube cleaning device which comprises a transverse plate, a plurality of through holes are formed in the middle area of the transverse plate, a fire tube is inserted into each through hole in a penetrating mode, the transverse plate can move up and down in a reciprocating mode, and four spiral strips are arranged on the outer edge face of each fire tube. Four spiral strips on each fire tube are identical in rotating direction and spiral angle and are circumferentially and uniformly distributed around the axis of the fire tube, an annular block is rotationally connected into each through hole, bristles are uniformly distributed on the inner edge surface of each annular block along the circumference, the annular blocks can rotate when moving up and down in a reciprocating mode along with the transverse plate, and a plurality of shifting pieces capable of swinging up and down are hinged to the upper end and the lower end of each through hole. The shifting piece can impact the spiral strip when moving up and down along with the transverse plate; the reciprocating movement of the transverse plate is matched with the spiral strip, the spiral strip is knocked through the shifting piece while the annular block spirally cleans scale on the outer wall of the fire tube, vibration of the fire tube is achieved, soot is effectively prevented from being attached to the inner wall of the fire tube to form carbon deposition, the heat conduction efficiency of the fire tube is greatly improved, and the service life of the fire tube is greatly prolonged.

Description

technical field [0001] The invention relates to the field of fire tube boilers, in particular to a boiler fire tube cleaning device. Background technique [0002] Fire tube boiler, also known as shell boiler, its principle is to use the heat of flue gas generated by combustion to heat water, but after long-term use, carbon deposits will be formed in the fire tube used for heat transfer, and it will come into contact with water Scale will also adhere to the outer edge of the boiler. Scale and carbon deposits will affect the heat transfer of the fire tube, greatly increase the energy consumption of the boiler, and even block the pipeline so that it cannot be used normally; [0003] The fire pipes in the prior art often use serpentine or light pipes, and the heat transfer efficiency is low. There are some devices for cleaning the fire pipes in the prior art. To achieve cleaning, some even need to be cleaned in a stopped working state, and it is difficult to clean both the insi...
