Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a muffle furnace crucible placing device. Background Art

[0002] Muffle furnace is a commonly used testing and experimental equipment. The traditional processing method is to put the crucible into the muffle furnace without support or use a crucible stand to put it into the muffle furnace for processing. The traditional crucible stand usually has 6-8 holes, which takes up a large space for the vessel and has a small batch processing volume. After processing, the temperature in the muffle furnace is still very high, and it takes a long time to cool down before the crucible in the muffle furnace can be taken out. It is also very inconvenient to take and send, and the crucible stand needs to be supported by hand for taking and sending. This requires the crucible stand to be kept stable at all times to avoid tilting accidents, resulting in sample loss and experimental failure. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a muffle furnace crucible placing device, which overcomes the defects of the prior art, has a simple structure, is easy to use, can improve experimental efficiency, shorten experimental time, and ensure experimental safety.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A muffle furnace crucible placement device comprises a bottom crucible rack, the bottom crucible rack is provided with a bottom flat plate with a plurality of crucible placement holes, four bottom support columns are fixedly connected to the four corners of the bottom flat plate; the upper ends of the bottom support columns are hollow, and the lower ends are provided with universal wheels; the upper ends of the bottom support columns are plugged and connected to a top crucible rack, the top crucible rack comprises a top support column plugged and connected to the bottom support column, the upper end of the top support column is fixedly connected to the top flat plate with a plurality of crucible placement holes; a handle is provided on one side of the bottom flat plate.

[0006] Preferably, the upper end of the top support column is hollow, and a frame of a layer of crucible rack can be plugged and connected thereon, so as to better meet the requirements of batch experiments.

[0007] Preferably, the crucible placement holes are arranged in a honeycomb shape, so that the flat plate space can be utilized to the maximum extent and as many crucibles as possible can be placed.

[0008] Preferably, the crucible placement hole on the top plate can be configured to be suitable for placing a 30 mL or 50 mL crucible.

[0009] Preferably, the crucible placement hole on the bottom plate can be configured to be suitable for placing a 30 mL or 50 mL crucible.

[0010] In this way, different combinations can be made according to needs, and materials of the same or different qualities can be processed in batches at the same time.

[0011] Preferably, the handle is adapted to a pick-up and delivery handle. The time spent on cooling can be reduced by taking and placing the crucible frame body through the pick-up and delivery handle. At the same time, the frame body moves along a plane during taking and placing, avoiding the loss of experimental materials caused by tilting.

[0012] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model effectively solves the problem of batch experiments by arranging a multi-layer frame; by arranging a universal wheel, the crucible frame can be pushed into the muffle furnace or pulled out more easily; the cooperation of the handle and the take-and-feed handle can reduce the time consumed for cooling, and the crucible frame can be pulled out as a whole without waiting for the furnace cavity to be completely cooled, and the crucible frame and the sample can be placed outdoors together to accelerate cooling; at the same time, the frame body of the crucible frame moves along a plane when taking and placing, so as to avoid the loss of experimental materials caused by tilting.

[0014] In short, the utility model has a simple structure, is easy to use, can improve experimental efficiency, shorten experimental time, and ensure experimental safety. BRIEF DESCRIPTION OF THE DRAWINGS
