Abstract

The invention discloses a rotary multilayer porous crucible bracket, relates to a laboratory detection appliance, and solves the problem that a crucible used in a laboratory detection process is not easy to place and cannot meet the requirement of large-batch detection due to disorder placement. The rotary multilayer porous crucible bracket comprises a chassis, a vertical shaft, multiple layers ofcrucible trays arranged on the vertical shaft and a bracket cover. Each crucible tray comprises an annular tray surrounding edge and a tray body connected into the tray surrounding edge, the bottom surface of the tray body is higher than that of the tray surrounding edge, the upper surface of the tray body protrudes out of the tray surrounding edge, a rotating shaft sleeve hole is formed in the bottom of the tray body, a rotating shaft is arranged on the upper surface of the tray body, and a plurality of holes used for placing crucibles are formed in the tray body. The crucible tray on the bottommost layer is detachably connected with the chassis in a sealed mode, the crucible trays on the upper and lower layers are detachably connected in a sealed mode, and the crucible tray on the top layer is detachably connected with the bracket cover in a sealed mode. The device is beneficial to improving the stability and accuracy of detection work, and the practical design of the device is beneficial to enhancing laboratory management and facilitating laboratory operation.

Description

technical field [0001] The invention relates to a laboratory testing device, in particular to a rotary multi-layer porous crucible bracket. Background technique [0002] Graphite crucible has good thermal conductivity and high temperature resistance. During high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and rapid cooling. It has strong corrosion resistance to acid and alkaline solutions and has good chemical stability. Graphite crucibles for melting gold, silver, platinum and other precious metals and other alloys have high temperature resistance, good oxidation resistance and corrosion resistance, and long service life. Therefore, crucibles are often used in laboratory testing projects, but at present, crucibles are purchased in bulk, and they are also scattered in the laboratory. During project testing, a flat-bottomed plate is required to hold these crucibles. It is easy to knock over some crucible...
