2, apparatus of the present invention dependable performance, cost is lower, and the scale and corrosion product analytical sample processed can reach the analysis requirement of experiment fully.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
The automatic preparation facilities of a kind of power plant scale and corrosion product analytical sample, as shown in Figure 1, base 13 and be packed in the square set 1 on base, be fixedly mounted with motor 2 at the cantilever tip middle part, motor shaft 3 straight down, the upper millstone 5 of bottom and horizontal positioned is affixed, at the upper millstone center to having the blanking hole 4 that connects upper millstone between edge, be shaped with on hemispherical and grind agate particle 6 at the upper millstone lower surface, below upper millstone by with the affixed crossbeam 10 of support vertical beam, being fixedly mounted with lower millstone 9, upper surface at lower millstone is shaped with hemispherical lower grinding agate particle 7, having the powder leakage hole 8 that connects lower millstone near lower millstone edge, be fixedly mounted with 120 purpose screen clothes 11 by support vertical beam level below lower millstone, be placed with electronic scale 14 below screen cloth, be provided with the weight readings circuits for triggering in electronic scale, circuits for triggering output triggers stopping modular with motor and is connected by wire 12.
In specific embodiment of the invention, described upper millstone adopts the agate material, and its diameter is 25-30cm, the mill that thickness is 5-8cm, and described lower millstone is identical with the upper millstone material, measure-alike.
In specific embodiment of the invention, through repetition test, for can being reached, polished scale and corrosion product analyzes the desired standard of experiment, the diameter of the hemispherical upper grinding agate particle that described upper millstone lower surface is shaped with is 2.5-3.0mm, the diameter of the hemispherical lower grinding agate particle that described lower millstone upper surface is shaped with is 3.0-3.5mm, and, it is 2.0-2.5mm that described upper grinding agate particle protrudes the upper millstone lower surface, every distance between the agate particle in twos is 0.5-1mm, it is 1.0-1.2mm that described lower grinding agate particle protrudes the lower millstone upper surface, every distance between the agate particle in twos is 1-1.5mm.
