Anti-blocking rapping device for coal dropping pipe of thermal power plant and using method thereof

Abstract

The invention discloses an anti-blocking rapping device for a coal dropping pipe of a thermal power plant and a using method thereof. The anti-blocking rapping device comprises the coal dropping pipe, an upper fixing ring, a lower fixing ring and a mounting frame, the coal dropping pipe is provided with the upper fixing ring, the lower fixing ring is arranged below the upper fixing ring, rubber mats are arranged on the inner wall of the upper fixing ring and the inner wall of the lower fixing ring, fixing bolts are arranged on one side wall of the upper fixing ring and one side wall of the lower fixing ring, the mounting frame is arranged between the upper fixing ring and the lower fixing ring, a sliding sleeve is arranged on the mounting frame, and an electric push rod is arranged at the top end of the sliding sleeve. The anti-blocking rapping device has the beneficial effects that by arranging the sliding sleeve and a hydraulic rod, in the working process of the device, the electric push rod pushes the sliding sleeve to move downwards, then the sliding sleeve drives a vibration mechanism to move downwards, a vibration ball can integrally beat the coal dropping pipe, the dredging effect of the coal dropping pipe is guaranteed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of anti-blocking and rapping devices, in particular to an anti-blocking and rapping device for coal falling pipes in thermal power plants and a method for using the same. Background technique [0002] Coal drop pipe is a general term for coal transportation pipelines in coal, ports, thermal power, coal dump stations, coal washing plants, coal-fired industrial boilers and other industries. Coal drop pipes generally include coal drop hoppers, downpipes, diversion troughs and other components. The longer coal drop pipe also needs to increase the air lock to reduce dust. When diverting, additional components such as diverting flap doors are added, and anti-blocking and rapping devices are required to dredge the coal falling pipe during use. [0003] During the use of the existing anti-blocking and rapping device for coal falling pipes in thermal power plants, since the installation position of the vibrator is ...

AI Technical Summary

Problems solved by technology

[0003] During the use of the existing anti-blocking and rapping device for coal falling pipes in thermal power plants, since the installation position of the vibrator is fixed and the coal falling pipe has a certain length, the vibration force of the vibrating machine will increase with the transmission distance during the working process of the device. increase and weaken, which affects the dredging effect of the device and reduces the practicability of the device. Secondly, during the use of the anti-blocking and rapping device of the coal falling pipe in the existing thermal power plant, due to the working environment of the coal falling pipe, the outer wall of the coal falling pipe The surface will be covered with coal dust, and when the device vibrates the coal falling pipe, the coal dust will permeate the atmosphere, which will affect the air quality and reduce the environmental protection of the device. In addition, the anti-blocking vibration of the existing thermal power plant coal falling pipe During the use of the beating device, it is impossible to adjust the vibration strength of the device, which will affect the working efficiency of the device and reduce the functionality of the device. Therefore, an anti-blocking and rapping device for coal falling pipes in thermal power plants is urgently needed to solve the existing problems
