Momentum impact hammer

Abstract

The invention discloses a momentum impact hammer, which solves the problem of poor dredging effect of the existing device, and the characterized of impact hammer comprises a left support, a right support, a cylinder body, a connecting rod, a hammer body, the left and right supports are connected by connecting rods. The cross-section of the hammer body is slightly smaller than that of the cylinderbody, which is an integral rod shape. Comprises end head, grooves I, grooves II, arc-shaped hammer head. The arc-shaped hammer head is provided with an impact surface. The end head is covered with buffer pad, the groove I is provided with Y-shaped sealing ring, and the groove II is provided with wear-resistant belt. Momentum impact hammer has the advantages of simple structure, low manufacturing cost, convenient installation, quick maintenance, direct use of a hammer body for vibration strike, large vibration strike momentum, and a strong hammer body, which is not easy to break, can be betterused for vibrating strike on a hopper, and is especially suitable for dredging the raw coal hopper of a thermal power plant. Ihe invention can also be widely used in chemical, fertilizer, food, ceramics, glass, cement, pharmaceutical, plastic, fuel and other powder processing industries.

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
