Hopper bin wall vibrating air hammer

Abstract

The invention discloses a hopper bin wall vibrating air hammer. The hopper bin wall vibrating air hammer solves the problem that an existing device is ineffective in removing coal blockage failure and is characterized by further comprising a left supporting seat, a right supporting seat and a hammer. Air inlet holes, air inlet channels and circular bosses with grooves are arranged on the left supporting seat and the right supporting seat, the circular bosses and a cylinder body are in a threaded connection, first sealing rings are arranged on the circular bosses on the left supporting seat and the right supporting seat, and first rubber blankets are arranged on the end surfaces of the circular bosses; two to three grooves are arranged in a piston, second sealing rings are arranged in the grooves, and impact resistant second rubber blankets are arranged on both sides of the grooves; and third sealing rings and the like are arranged on the connecting portion of the right supporting seat and a piston rod. The hopper bin wall vibrating air hammer is simple in structure and low in manufacturing cost. The whole device is installed outside the hopper bin wall, so examination and maintenance are fast and convenient; the hopper bin wall vibrating air hammer is particularly suitable for dredging of a thermal power plant raw coal hopper, and can effectively solve the phenomena of coal flourishing, arch-forming and coal blockage in operation, and can also be widely applied to powder processing industries such as chemical engineering, fertilizer, food, ceramic, glass, cement, pharmacy, plastic and fuel.

Description

technical field [0001] The invention belongs to a dredging device in the conveying process of solid granular materials, more precisely, it belongs to an air hammer for clearing the clogging of a hopper and smoothing the material conveying. Background technique [0002] For a long time, the frequent blockage of coal in the raw coal bunker has been a very important problem that plagues the normal operation of thermal power plants, especially in cloudy and rainy days when the surface moisture of the coal is high, which not only seriously affects the safe operation of the boiler, but also causes certain economic losses. The loss will also pose a threat to the personal safety of workers, which not only affects safety but also affects economy. Common clogging phenomena in raw coal bunkers mainly include jamming, arching, agglomeration, and adhesion. [0003] There are certain deficiencies in the existing methods, which can only alleviate the problem to a certain extent or solve t...

AI Technical Summary

Problems solved by technology

[0003] There are certain deficiencies in the existing methods, which can only alleviate the problem to a certain extent or solve the problem in a short time, and cannot fundamentally eliminate the coal blocking fault, especially for wet coal and viscous coal. Great inconvenience caused by production

For example: the warehouse wall vibrator or the warehouse wall exciter uses high-frequency vibration instead of manual knocking. The disadvantage is that the efficiency is not high, and the arch bridge formed by the material cannot be damaged. It may tear the coal bunker weld seam, loosen the anti-blocking coal liner on the hopper wall, and cause damage to the coal bunker; the air cannon has a small action area, which is easy to form rat holes, and the application effect is not good
