2, apparatus of the present invention dependable performance, cost is lower, and the scale and corrosion product analytical sample processed can reach analysis design mothod requirement completely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Be further described the embodiment of the present invention below in conjunction with accompanying drawing, 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 the square set 1 be packed on base, motor 2 is fixedly mounted with in the middle part of cantilever tip, motor shaft 3 straight down, the upper millstone 5 of bottom and horizontal positioned is affixed, the blanking hole 4 of through upper millstone is had between upper millstone center to edge, upper millstone lower surface be shaped with hemispherical on grind agate particle 6, lower millstone 9 is fixedly mounted with by the crossbeam 10 affixed with support vertical beam in the below of upper millstone, hemispherical lower grinding agate particle 7 is shaped with at the upper surface of lower millstone, the powder leakage hole 8 of through lower millstone is being had near lower millstone edge, 120 object screen clothes 11 are fixedly mounted with by support vertical beam level in the below of lower millstone, electronic scale 14 is placed with below screen cloth, weight readings circuits for triggering are provided with in electronic scale, circuits for triggering output is triggered stopping modular with motor and is connected by wire 12.
In specific embodiment of the invention, described upper millstone adopts agate material, and its diameter is 25-30cm, and thickness is the mill of 5-8cm, and described lower millstone is identical with upper millstone material, measure-alike.
In specific embodiment of the invention, through repetition test, standard required by analysis design mothod is reached in order to enable the scale and corrosion product be polished, 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 upper millstone lower surface, every distance between two between agate particle is 0.5-1mm, it is 1.0-1.2mm that described lower grinding agate particle protrudes lower millstone upper surface, every distance between two between agate particle is 1-1.5mm.
In specific embodiment of the invention, described blanking hole is upper diameter is 3cm, lower diameter be 2cm to conical blanking hole, described blanking hole has two, is positioned at same by the center of circle diametrically; The cylindric powder leakage hole of described powder leakage hole to be diameter be 1cm, the horizontal centre of blanking hole and powder leakage hole is apart from being 10cm, and described powder leakage hole has 8, lays respectively at by the center of circle and is in 4 of miter angle diametrically; In process of lapping, scale and corrosion product is come between upper lower millstone by blanking hole, and in the process of grinding, scale and corrosion product is pushed to mill edge rotate the drive of centrifugal force at upper millstone while pulverizing under gradually, is finally fallen by powder leakage hole.
