Abstract
The invention provides a coal as fired sampling machine, which comprises a mechanical sampler, a sample preparation system and a sampling control system, wherein the sampling control system segments and disassembles the operation process of the coal as fired sampling machine as required, the operation mode of the coal as fired sampling machine is redefined, and the mechanical sampler adopts different operation modes in different sampling processes, so that the operation time of the coal as fired sampling machine is shortened, and the electric energy consumption of the coal as fired sampling machine is reduced; and the mechanical sampler is a sampling head, and the sample preparation system comprises a primary feeder, a crusher, a divider, a material discarding machine, a collecting barrel,a secondary feeder and an electrical control device. The invention further provides a corresponding energy-saving operation method, the operation process of the coal as fired sampling machine is divided again, each movement of the sampling head is counted as one sampling process, each sampling process is divided into three stages, namely, judgment, material existence and material waiting, and then efficient and energy-saving operation of the coal as fired sampling machine is achieved.
Description
technical field [0001] The invention relates to the thermal automation technical field of a thermal power plant, in particular to a furnace coal sampling machine and an energy-saving operation method thereof, which can be applied to the control program of the furnace coal sampling machine of a thermal power plant. Background technique [0002] The operation mode of the existing furnace coal sampling machine is automatic operation with the opening of the coal conveying belt. The waste of electric energy. Generally, the energy-saving mode of the existing furnace coal sampling machine is to turn off the crusher to achieve a certain energy-saving effect. Specifically, only the first feeder and the crusher are stopped, while the second feeder and the waste belt are still in operation. There is still a lot of power loss in the sampling process. Contents of the invention [0003] In order to overcome the above-mentioned problems existing in the prior art, the object of the pres...
