Description
Technical Field
The utility model relates to a pipeline mediation field, concretely relates to coal breakage pipeline pull throughs.
Background
The economic benefit of coal-fired thermal power plants is increasingly close to the cost of raw coal, and the requirement on the cost of the raw coal is increasingly high, so that the diversity of coal types also becomes a normal state. Because of different coal types, the moisture content in some raw coals is higher, so that the raw coals are easy to harden, the fluidity is poorer, and the blockage fault is easy to cause in a raw coal bin or a coal dropping pipe.
Sludge coupling power generation is a new base point of urban environment-friendly markets in future, dried and concentrated sludge is directly mixed into a raw coal bunker and is sent into a hearth for combustion, and the method is a scientific efficient environment-friendly solution for urban sewage and waste. However, the sludge mixed in the coupling power generation is unstable due to the concentrated index, and the technology of mixing the sludge into the raw coal bunker is still to be improved, so that the sludge is mixed, the coal blockage fault in the raw coal bunker is frequent, the coal blockage position is usually at the interface of a cone section and a straight column section of the raw coal bunker, and the coal falling resistance of the straight column section is the friction force of a coal falling pipe, so that the resistance is relatively small, and the pipe is not easy to block coal. For a raw coal bunker with a slope, the downward leakage resistance of raw coal is relatively large, and the coal covering is easy to be carried out on the position of the junction surface of a downward slope section and a straight cylinder section of the coal bunker under the action of stress among the raw coal, namely, no coal is arranged below the junction surface.
In the prior art, after the coal blockage fault occurs, the manual beating mode is usually adopted to dredge the coal blockage, however, the manual beating mode often has the following defects:
1. aiming at coal blockage at a specific part, the problem of high-altitude operation is firstly faced when the raw coal bin is knocked manually, and due to the fact that the position of the raw coal bin is high, a maintainer knocks the raw coal bin forcefully at a high place, and certain personal safety hazards exist.
2. Knocking at the same position for a plurality of times for a long time easily leads to the deformation of the raw coal bunker, so that the knocked part is sunken in the coal bunker and is easily ground to be thin by coal flow, and the equipment has potential safety hazards.
3. Under the condition that the coal blockage situation is complex, the knocking operation can reach more than 8 hours, the working strength is high, and the labor cost is greatly improved.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
