The invention discloses a powder trace weighing device and belongs to the technical field of sampling and weighing equipment. The invention mainly aims to make the operation of the sampling and weighing of coal and the like simple, save labor, improve working efficiency, avoid errors and improve the accuracy of analysis results. According to the main technical schemes of the invention, the weighing device comprises a moving mechanism, a driving mechanism, a discharging mechanism, a weighing mechanism and a controller; the driving mechanism is arranged on the moving mechanism and moves under the driving of the moving mechanism, so that the driving mechanism can be connected with the discharging mechanism; the discharging mechanism discharges powder in a sample bottle into a crucible under the driving of the driving mechanism; the weighing mechanism is used for weighing the weight of the powder in the crucible; and the controller is electrically connected with the lifting mechanism, the driving mechanism, the discharging mechanism and the weighing mechanism and is used for controlling the mechanisms to perform corresponding actions and recording the weighing result of the weighing mechanism. The powder trace weighing device of the invention is mainly used for sampling and weighing coal and the like.
Description
technical field [0001] The invention relates to the technical field of sampling and weighing equipment, in particular to a powder micro weighing device. Background technique [0002] At present, coal-related industries, such as power plants, coal plants or steel mills, generally settle accounts based on the weight of the coal after moisture has been removed, making the moisture content of a batch of coal an important factor affecting coal prices. Therefore, Before the coal can be settled, it is usually necessary to test the moisture content of the coal. [0003] In the prior art, a drying method is usually used to test the water content of coal, and the method includes sampling and weighing of coal. At present, laboratory personnel usually need to prepare sampling tools, sample containers, and weighing equipment for coal sampling and weighing according to the provisions of the laboratory items. Low, and prone to error, affecting the accuracy of the analysis results. Cont...
