Description
Technical Field
The invention relates to a vibration excitation filler mixing device and a filler mixing method of a spectrum sample, in particular to special equipment for mixing multiple component analysis samples in batches on a mixer and automatically filling the samples into an end hole of a carbon rod for a test before spectrum analysis of a trace powdery sample in the geological mineral industry, belonging to the technical field of spectrum analysis test equipment of the powdery mineral sample.
Background
When geological mineral departments perform geological investigation and analyze mineral components by using a spectrometry, a plurality of small mineral samples are usually collected in the field in advance, then crushed and ground in a laboratory to obtain powder, a proper amount of catalyst is added to carry out material mixing treatment on the sample, the treated sample powder is filled into a carbon rod with a certain structure, finally, the sample is subjected to a spectrometry test, and the elemental components and the content of the minerals are obtained through the spectrometry. In the process of treating a test sample, ground mineral powder is usually required to be placed in a crucible, and after a proper amount of powdery catalyst is added, the ground mineral powder and the crucible are uniformly mixed; these mixed samples were then filled into the machined holes of the test carbon rod (as shown at B in fig. 1). To meet the needs of spectroscopic testing, multi-component experimental samples are typically required and processed by lot classification.
The automatic stirring and mixing device is characterized in that an eccentric shaft is arranged at the upper end of a main vibration motor and penetrates through an upper chassis to be connected with a crucible tray, an output shaft is arranged at the lower end of the main vibration motor, a rotating motor is arranged at the central part of the main vibration motor and the inclined chassis fixed on an inclined bracket, the lower bottom part of the inclined bracket is fixed on a base, supporting springs are uniformly distributed between the upper chassis and the rotating tray, the crucible tray is positioned between the upper chassis and the rotating tray, a plurality of crucible fixing holes are uniformly formed in the disc surface of the crucible tray, a transparent cover plate is covered on the disc surface of the crucible tray, and a fastening handle is arranged at the center of the center to press and connect the transparent cover plate and the crucible tray into a whole. The device can be used for stirring and mixing various powder materials filled in the crucible, and has the advantages of high stirring speed and good stirring effect; the defects are that: after the materials are mixed, the powder in the crucible is required to be poured out, and then the powder is manually filled into the carbon rod, so that the automatic filling cannot be realized. Therefore, a great deal of labor is needed to process the test piece before the spectrum analysis test is carried out, so that time and labor are wasted, and the filling compaction effect is poor; in addition, the inclination angle of the inclined bracket described in the proposed structural scheme is fixed, and experiments show that the inclined bracket cannot be suitable for efficient stirring and mixing of the multi-component mineral powder with different granularity.
The chinese patent application (mixing, stirring or dispersing method) and apparatus therefor (201180047615.4) a method of mixing, stirring or dispersing materials, the apparatus comprising a housing and a container having a mixing chamber into which a rod-shaped element extends. The rod-shaped element is connected to a membrane, which is a component of the wall of the container, at the inlet into the mixing chamber. For processing the contents of the mixing chamber, the rod-shaped element is moved together with the membrane by the drive means. In order to avoid an unexpected failure of the diaphragm, the number of revolutions of the drive is counted within the scope of the method, and the drive is switched off when the maximum number of revolutions allowed for the load-carrying capacity of the diaphragm and the load-carrying variable resulting therefrom are reached. The equipment or the method is only suitable for mixing mass materials with the same components, and the residual materials in the equipment are more, so that the equipment needs to be cleaned when the components of the materials to be mixed change.
Since a plurality of batches of test pieces with different components (namely, carbon rods filled with mineral powder mixture in a cavity at one end) are usually required in the geological survey spectral analysis, the mass of the mineral powder mixture filled in each test piece is small, and the weight of the mineral powder mixture is usually only a few grams. In order to improve the spectral analysis test efficiency of mineral powder, reduce the test cost, save manpower, etc., the invention provides an automatic mixing and packing integrated device for spectral analysis samples, which is particularly necessary and has great significance.
