Lofting device of rocking furnace

Abstract

The invention discloses a lofting device of a rocking furnace. The lofting device comprises a top cover, a connecting assembly arranged at the bottom of the top cover and a lofting mechanism, the lofting mechanism comprises at least one group of first lofting assembly and second lofting assembly which are arranged at intervals in the axial direction; the first lofting assembly comprises at least two first clamping plates which are arranged in parallel at intervals to form at least one first lofting accommodating position; the second lofting assembly comprises at least two second clamping plates which are arranged in parallel at intervals to form at least one second lofting containing position, the first lofting containing position and the second lofting containing position are provided with a first limiting piece and a second limiting piece respectively, and the arrangement directions of the first lofting containing position and the second lofting containing position are different so that the projections of the first lofting containing position and the second lofting containing position in the axial direction can intersect. The crossed part of the axial projection is matched with the first limiting piece and the second limiting piece to form a plurality of lofting spaces; the lofting device is firm in lofting, a plurality of sample tubes can be placed, the lofting device can adapt to the sample tubes of different sizes and specifications, and the working efficiency and the equipment utilization rate are improved.

Description

technical field [0001] The invention relates to the technical field of swing furnaces, in particular to a setting-out device of a swing furnace. Background technique [0002] Swing furnace is a special high-temperature equipment specially developed for colleges and universities, scientific research institutes and industrial and mining enterprises to sinter, melt, analyze and detect metal, non-metal and other compound materials in atmosphere or vacuum state. The system is integrated with the box-type furnace body. In the furnace body, resistance wires are generally used as heating elements, and corundum tubes or quartz glass tubes are used to cross the middle of the furnace body as the furnace chamber. The heating elements and the furnace chamber are parallel and evenly distributed outside the furnace chamber. When using the swing furnace, the chemical sample is first sealed in a quartz test tube (the sealing method is generally to melt a cylindrical quartz glass plug inside ...

AI Technical Summary

Problems solved by technology

At present, the common swing furnace lofting device is generally a high temperature resistant stainless steel round rod. When in use, there are generally two ways to fix the quartz test tube: one is to tie the quartz test tube to the stainless steel round rod with iron wire. This method depends on the length of the rod. And the size of the test tube, you can fix multiple quartz test tubes at a time, but the disadvantage is that it is time-consuming and laborious (need to wind multiple layers of iron wire), and it is difficult to judge whether it is fixed firmly (whether it will be loose during the swing process), and if you use too much force during the binding process, It is easy to crush the relatively thin and fragile quartz test tube, resulting in waste of chemical samples; the second is to penetrate the end of the stainless steel round rod into the quartz test tube, withstand the quartz plug inside the test tube, and then place the other end of the test tube against the furnace wall , so as to fix the quartz test tube. Although this method is relatively reliable and time-saving and labor-saving, the disadvantage is that only one quartz test tube can be fixed at a time, and the efficiency is extremely low, and the diameter of the stainless steel rod must not be greater than the inner diameter of the quartz test tube. Fixable quartz cuvettes are limited in size
