Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence analysis sample preparation equipment, in particular to a grinder for fluorescence analysis sample preparation. Background Technique

[0002] Sample preparation by grinding and pressing tablets is a commonly used sample preparation method for X-ray fluorescence spectrometry. The general sample preparation steps are as follows: after the sample is broken, it is dried, processed to a certain particle size by a grinding device, and finally pressed into a stable round tablet by a tablet pressing device. The method of making cuttings powder from massive cuttings is to grind the cuttings. At present, the common method is to use an ordinary mortar and grind it manually. The grinding effect is low, the noise is large, and it is extremely easy to generate dust pollution.

[0003] The utility model patent with the patent application number "201822258156.6" discloses a geological logging cutting grinding device, which grinds the cuttings by using the grinding teeth through the rotation of the grinding rod, improving the grinding efficiency of the cuttings. Although this device replaces manual grinding with machine grinding, it cannot adjust the particle size of the cutting samples. In addition, the metal grinding teeth and the grinding rod are extremely easy to contaminate the samples, affecting the fluorescence analysis results. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model

A control panel is provided on the front side of the machine housing. A rotating grinding disk is provided in the grinding chamber. The rotating grinding disk is slidably and sealingly fitted with the inner wall of the grinding chamber. One end of the rotating grinding disk is assembled and connected to the main shaft. A chamber cover is hinged to one end of the grinding chamber. A fixed grinding disk is provided on the inner side of the chamber cover. A feeding chute is installed on the side of the chamber cover. The discharging end of the feeding chute penetrates through the center position of the fixed grinding disk. The chamber cover and the grinding chamber body are assembled and fixed through a lock. A horizontal adjustment mechanism is provided in the machine housing. A driving mechanism is provided on the moving end of the horizontal adjustment mechanism. The output end of the driving mechanism is assembled and connected to the main shaft. Both the rotating grinding disk and the fixed grinding disk are zirconia grinding disks. An aggregate chute is provided at the bottom of the grinding chamber.

[0006] The above horizontal adjustment mechanism includes a lead screw module, a guide member and a moving seat. The lead screw module is arranged in the machine housing. The guide members are symmetrically arranged on both sides of the lead screw module. The moving seat is installed on the moving end of the lead screw module and is connected to the guide member.

[0007] The above guiding member includes a guide rail and a slider. The guide rails are symmetrically arranged on both sides of the lead screw module. The slider is slidably sleeved on the guide rail and fixedly connected to the moving seat.

[0008] The above driving mechanism includes a frame arranged on the moving seat. A driving motor is installed on the frame. A speed reducer is installed below the driving motor. The input end of the speed reducer is connected to the output end of the driving motor through a pulley and a belt. The output end of the speed reducer is connected to the main shaft.

[0009] The utility model provides a grinding machine for fluorescence analysis sample preparation, which has the following beneficial effects: for the grinding machine for fluorescence analysis sample preparation, both the rotating grinding disc and the fixed grinding disc are zirconia grinding discs, with strong abrasion resistance and can effectively avoid sample contamination. The rotating grinding disc and the fixed grinding disc are used in cooperation, and the gap between the two grinding discs is used to realize the grinding operation of rock samples, with low noise and no generation of a large amount of dust. At the same time, when rock chip samples with different particle sizes are required, the horizontal adjustment mechanism can finely adjust the horizontal positions of the driving mechanism and the rotary grinding disc, and then adjust the gap between the rotating grinding disc and the fixed grinding disc, so as to obtain rock chip samples with different particle sizes, which is convenient for the subsequent smooth progress of fluorescence analysis operations.
