Automatic coal blending system

Abstract

The invention discloses an automatic coal blending system which is used for blending a first kind coal and a second kind of coal with different burning points into blended coal with a required burning point in accordance with a preset proportion. The automatic coal blending system comprises a weighing unit, a blending unit and a control unit, wherein the weighing unit comprises two weighing mechanisms which are respectively used for weighing the coal; each weighing mechanism comprises a containing hopper and a weighing hopper, wherein the containing hoppers are used for containing the coal, and the weighing hoppers are used for weighing the coal; a discharge port of each weighing hopper extends to a corresponding transmission mechanism; a discharge mechanism and a weighing device are arranged on each weighing hopper; each weighing device is in signal connection with the control unit; and a driving charge motor is in signal connection with each control unit. The required coal is accurately weighed by the weighing devices composed of weighing sensors, so that the quantity of the coal in the weighing hopper can be monitored in real time, and the excessive problem does not easily occur. The whole system is electrically and mechanically controlled, therefore, the automatic coal blending system has the advantages of more accuracy and high efficiency, the labor intensity of workers is reduced, a large scale can be realized, and the requirements of all fields can be satisfied.

Description

technical field [0001] The invention relates to a coal blending system. Background technique [0002] In different industrial fields, specific coals with different combustion points are often required, which requires mixing and blending with coals with different combustion points, but this amount is quite large. In the prior art, manual weighing is generally used And mixed deployment, not only the labor cost of workers is high, but also the efficiency is extremely low, which cannot meet the demand. Contents of the invention [0003] The purpose of the present invention is to provide a coal blending system capable of large-scale and precise deployment of coal at the required combustion point. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A coal blending system, which is used to mix the first type of coal and the second type of coal with different combustion points into...
