Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the best implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] First, refer to figure 2 The overall structure of the coal blending system involved in the present invention is introduced in detail. As shown in the figure, the coal blending system includes six raw coal silos T1-T6 arranged side by side, and each raw coal silo T1-T6 is filled with one kind of raw coal. Above the six raw coal silos T1-T6, there is a second raw coal conveyor belt P2 that can move horizontally with a reversible trolley not shown in the figure, and one end of the second raw coal conveyor belt P2 is connected to a storage tank for stacking on the ground. Various raw coals are lifted and transported to the first raw coal conveyor belt P1 on the second raw coal conveyor belt P2. The reversible trolley is driv...

Abstract

The invention relates to a coal distributing system which comprises a plurality of raw coal barrel bins, coal feeders, a barrel bin lower belt scale, a coal distribution conveying belt and a coal distributing control device, wherein the raw coal barrel bins are used for respectively storing different kinds of raw coal; and the coal feeders are arranged at the lower parts of all raw coal barrel bins along the axis directions of the raw coal barrel bins; each coal feeder is provided with a shell, a circular coal outlet, a coal distributor and a scraper; the shell is in an inverted cone platform shape, the upper part of the shell is opened, and the lower part is provided with a flat plate-shaped base plate; the circular coal outlet is arranged at the central part of the base plate; the coal distributor is conic and is arranged at the upper side of the coal feeder and arranged on a rod-shaped bracket which is fixedly installed on the shell so that the raw coal falling from the raw coal barrel bins uniformly slide to be near to the coal outlet along the conic surface; the scraper is in a curve shape extending along the flat-plate-shaped base plate and is arranged on a rotatable fixed bracket extending out from the coal outlet; and when the scraper rotates, the scraper is used for scraping the raw coal in the coal feeders into the coal outlet. According to the structure, the coal distributing system can realize precise coal distribution and has compact structure.

Description

technical field [0001] The present invention relates to a coal blending system, more specifically, it relates to a coal blending system that mixes different types of raw coal according to a designed coal blending plan to accurately prepare coal blending that meets the requirements of a power plant, and the coal blending system used in the coal blending system Coal feeder. Background technique [0002] At present, there are a large number of thermal power plants built in various parts of China. However, each power plant has different requirements for coal quality and types of coal used. If coal that does not meet the requirements of the thermal power plant is used, the boiler operation of the power plant will be unstable and the combustion efficiency will be reduced, resulting in increased energy consumption and serious pollutant emissions, which will greatly affect the operation and maintenance of the boiler and the economic benefits of the power plant. impact, sometimes ca...
