Embodiment 1

[0033] like figure 1 As shown, it is a method of setting a dumper at the end of a coal unloading ditch provided in this embodiment. The implementation object of the transformation method in this embodiment is a traditional thermal power plant. On the basis of the coal unloading ditch, a new coal unloading method of the dumper is transformed, which includes the following steps:

[0034] Firstly, extend the railway line on the upper part of the slot coal unloading ditch. The general slot coal unloading railway line is narrower than the railway line used by the dumper. Therefore, it is necessary to widen the railway line while extending the railway line. The commonly used way of widening is mostly in the form of railway curves, that is, the extended railway track is bent and expanded outwards compared with the original one, so as to realize the widening of the railway line. The size of the widening can be processed according to the railway track parameters required by the actual...

Embodiment 2

[0046] This embodiment provides a coal unloading system for a power plant, including the method for arranging a dumper at the end of a coal unloading ditch described in Embodiment 1 above, and has all its technical advantages, which will not be repeated here.

Abstract

The invention provides a method for arranging a car dumper at the end of a coal-unloading ditch and a coal-unloading system for a power plant. The method for arranging the car dumper at the end of thecoal-unloading ditch comprises the steps of prolonging a railway line on the upper portion of the seam-like coal-unloading ditch; arranging the car dumper on the prolonged railway line; prolonging abelt-type conveyor to the lower side of the car dumper device. Based on seam-like coal unloading of an original thermal power plant, by prolonging the railway line on the upper portion of the seam-like coal-unloading ditch, installation of the car dumper device is achieved, the original belt-type conveyor is utilized to continue to convey coals dumped by the car dumper, it is achieved that the wayof coal unloading through a traditional seam-like coal-unloading ditch is transformed into the way of coal unloading through the car dumper, the coal-unloading device and the unloading railway line in the original power plant are effectively utilized, and the cost for transformation of the power plant is greatly saved.

Description

technical field [0001] The invention relates to the technical field of dumpers, in particular to a method for installing a dumper at the end of a coal unloading ditch and a coal unloading system for a power plant. Background technique [0002] In thermal power plants, coal is generally used as a raw material for power generation, so coal needs to be transported to power generation devices. [0003] The old coal transportation method of the power plant mostly adopts the slot type coal unloading ditch, and the coal unloading machine is used to dump the coal from the train into the coal unloading ditch, and then the impeller coal feeder unloads the material to the belt conveyor. However, the spiral coal unloader cannot clean the coal at the bottom of the train car, and it needs to manually clean up the remaining coal at the bottom of the car, which increases the amount of manual operation and poses safety risks. [0004] In view of the above problems, in the prior art, dumpers...
