Rapping device

Abstract

The invention discloses a rapping device. The rapping device comprises a rapping hammer capable of rotating, a hammer lifting module, a hammer falling module and a driving module; the hammer lifting module includes a rotating part, a swing arm and a return part; the rotating part can rotate; the swing arm is arranged on the rotating part in a swing manner; the return part normally drives the swing arm to locate in a hammer lifting position suitable for driving the rapping hammer to rotate; when the hammer lifting module rotates to a first position, the swing arm in the hammer lifting position drives the rapping hammer to rotate so as to lift up the rapping hammer; the hammer falling module is opposite to the swing arm; when the hammer lifting module rotates to a second position, the hammer falling module pushes the swing arm from the hammer lifting position to enable the rapping hammer to fall down; and the driving module is in transmission connection with the rotating part. According to the rapping device, the lifting and fall rapping of the rapping hammer can be realized, and the return part is provided for enabling the hammer lifting module to stably drive the rapping hammer, so that the working stability of the rapping device is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a rapping device. Background technique [0002] In related technologies, various furnaces in industrial production produce a large amount of high-temperature flue gas. In order to recover this part of waste heat, waste heat boilers are widely used now. However, the flue gas of industrial furnaces generally contains a large amount of smoke and dust, which is harmful to boilers. The heat transfer and operation of the boiler have a serious impact, so the dust accumulation inside the boiler and the pipeline directly affects the operating efficiency of the boiler. Currently operating waste heat boilers generally use compressed air soot blowers or mechanical vibrating machines to remove dust. The soot blower consumes a lot of power during use, which reduces the overall energy-saving effect. At the same time, it needs to blow a large amount of compressed air or steam into the furnace, ...

AI Technical Summary

Problems solved by technology

The soot blower consumes a lot of power during use, which reduces the overall energy-saving effect. At the same time, it needs to blow a large amount of compressed air or steam into the furnace, especially for the flue gas used for acid production, because the concentration of sulfur dioxide is reduced. It has a very adverse effect on the acid production; the long-axis mechanical rapping machine is driven by a motor through a reducer to rotate a long shaft. Many hammers are hung on the shaft at different angles. The hammers rotate with the shaft and naturally fall to strike the pipe wall to achieve clean Ash purpose; due to the small rapping force, the rapping frequency does not match the natural frequency of the pipe wall, mechanical rapping cannot cause the maximum effective vibration of the pipe wall, and the cleaning effect is not good. At the same time, due to the poor environmental conditions of the factory, the long axis is easy to The deformation caused the rapping machine to not operate normally, so the long-axis mechanical rapping machine has not been widely used
