Description
Technical Field
The utility model relates to a coal storage silo technical field particularly, relates to a hydraulic hammer for freezing material breakage.
Background
The storage bin is widely applied to coal and power generation enterprises, mines, stone plants and the like, and has huge storage. The structure form determines the natural defect that unsmooth blockage is easy to occur at the blanking opening, and particularly, the phenomena of wall adhesion and frozen blockage in different degrees commonly occur in the wet material or northwest cold areas.
The frozen wall is formed by gradually freezing a wet mud material on the inner wall of the blanking port at a low temperature, and after the wet mud material is gradually thickened, the blanking is more unsmooth and slower, and finally the frozen mud material is blocked. The freezing blockage is firm, the traditional manual dredging is usually very little in effect, and even the effect of detonator blasting is only partial material collapse and cannot be thoroughly solved. The serious influence is brought to the normal production, and the safety accident is very easy to cause by the dredging work; if the wall-sticking frozen plug is required to be dredged and cleaned, knocking and digging from the upper part of the material downwards is ineffective, and the most effective mode is that the frozen material is smashed and cleaned by using a machine with enough force to smash the frozen material from bottom to top.
At present, no special machine for crushing frozen materials in a storage bin exists, and the traditional storage bin blockage dredging machine mainly comprises an air gun, a loosening machine and a rotary blockage removing machine; the air cannon blows materials by taking compressed air as a medium, mainly plays a role in loosening fluffy materials in a small range, and is ineffective in freezing the materials; the loosening machine has the function of scraping and sweeping materials through the continuous reciprocating motion of the rake teeth, so that the effect of preventing the materials from being stuck on the wall is achieved, but for the condition that the materials are frozen and stuck into large blocks and are frozen and blocked in a storage bin which does not work for a long time, the rake teeth of the loosening machine are insufficient in structure and strength to crush and clean the frozen materials; the rotary blockage removing machine is used for scraping and sweeping through the rotation of the steel rod, the material is scraped and swept, the wall sticking prevention effect is achieved, the material is frozen and stuck to be a large block and a blocked situation for a long-time non-working bin, and the steel rod structure and the force of the rotary blockage removing machine cannot crush and clean the frozen material.
Therefore, the existing dredging machinery can not effectively and quickly crush and clean the materials frozen into blocks in the storage bin.
An effective solution to the problems in the related art has not been proposed yet.
