The method of determining the content of the element to be tested is to measure the fluorescence emission intensity generated by the atomic vapor of the element to be tested under the excitation of radiation energy.

The rotating frame 42 is rotatably connected to the fixed frame 21. The rotation of the support column 3 drives the rotating frame 41 to rotate, drives the rotating frame 42 hinged thereto through a pin shaft to rotate, thereby driving the crushing plate 4 hinged thereto through a pin shaft to rotate and rotate itself at the same time. The crushed solid waste heavy metals fall onto the outer surface of the frustum 31 through the filter screen 5. The rotation of the support column 3 drives the frustum 31 to rotate, grinding the crushed solid waste heavy metals;

[0040] When it is necessary to continue metering the solid waste heavy metals entering the dissolution tank 11, the ground solid waste heavy metals enter the dissolution tank 11 through the slide plate 6. When the solid waste heavy metals entering the dissolution tank 11 reach a certain amount, start the hydraulic cylinder 61. The telescopic movement of the telescopic rod of the hydraulic cylinder 61 drives the partition plate 62 fixedly installed therewith to rise and fall. When the partition plate 62 contacts the slide plate 6, it blocks the solid waste heavy metals. When the solid waste heavy metals are dissolved, start the water pump 7.
