Description

Technical field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to a rapping device with variable rapping quality for an electrostatic precipitator. [Background Technology]

[0002] The traditional rapping device includes a base, a hammer head and a hammer arm, wherein the hammer arm is hinged on the base, and the hammer head is installed at the lower part of the hammer arm. The mass of the hammer head and the length of the hammer arm are determined at the beginning of the design and generally cannot be changed. This makes the rapping mass and arm length of the rapping device immutable, and thus cannot provide a variable rapping force. The rapping device of the traditional structure is used in a wide range of occasions. At present, it is mainly used in electrostatic precipitators. In actual use of electrostatic precipitators, the rapping device is often required to provide a variable rapping force. The mass of the hammer head and the length of the hammer arm of the traditional rapping device are determined at the beginning of the design, and can only provide a specific rapping force. It cannot be arbitrarily changed according to actual needs. It is very easy to cause the rapping force to be too large or too small, and it is impossible to meet the rapping requirements well. Therefore, it is urgent to solve the above technical problems. [Utility Model Content]
