[0035] The bottom of the inner wall of the furnace tube 2 is in contact with a moving block 8, a cushion plate 9 is placed on the top of the moving block 8, a card slot for placing the cushion plate 9 is opened on the top of the moving block 8, a sample container 10 is arranged on the top of the cushion plate 9, a connecting bolt 18 is threadedly penetrated through the side part of the moving block 8, and a threaded hole 19 for mating with the penetration of the connecting bolt 18 is opened on the side part of the cushion plate 9.

[0036] Before the measurement work, the moving block 8 is moved so that the moving block 8 can move inside the furnace tube 2 and move to the pipe orifice of the furnace tube 2. Subsequently, the sample container 10 can be taken out from the inside of the furnace tube 2, and the slag filter is placed. Then, the sample container 10 is placed in the cushion plate 9, and the moving block 8 is moved to the middle end inside the furnace tube 2. Then, the connecting pipe 4 is inserted into the flange plate 1, and the heater 7 is started to melt the slag. During this process, the measurement results are displayed and predicted through the measuring camera 13 and the imaging system 12, thus completing the measurement work. The connection between the cushion plate 9 and the moving block 8 through the connecting bolt 18 and the threaded hole 19 can ensure the stable setting position of the cushion plate 9.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, in Embodiment 2, in order to horizontally and stably drive the moving block 8 and the sample container 10 to facilitate the filling of slag, as shown in Figure 1 and Figures 3-4 Figure 4, a synchronous driving mechanism is arranged between the moving block 8 and the lower support plate 3. The synchronous driving mechanism includes a driving screw 14, the driving screw 14 is rotatably arranged at the lower ends of the two flange plates 1, a vertical plate 15 is threadedly sleeved on the rod wall of the driving screw 14, a first magnetic block 16 is fixedly arranged at the top of the vertical plate 15, the first magnetic block 16 is in contact with the pipe wall of the furnace tube 2, a second magnetic block 17 is fixedly embedded at the bottom of the moving block 8, and the first magnetic block 16 and the second magnetic block 17 are arranged in cooperation;

[0039] The end of the driving screw 14 passes through the flange 1 and is fixedly provided with a rotating plate 24. A positioning block 25 is slidably inserted into the interior of the rotating plate 24. A plurality of circumferentially symmetrically arranged positioning grooves are formed at the lower end of the side wall of the flange 1.

[0041] Before the slag needs to be filled into the sample container 10, the positioning block 25 can be pulled through the pulling hole 27, so that the positioning block 27 is pulled out of the positioning groove, and the rotating plate 24 is rotated. At this time, the driving screw 14 rotates to make the vertical plate 15 move horizontally. At this time, under the magnetic cooperation of the first magnet 16 and the second magnet 17, the vertical plate 15 moves and the moving block 8 moves simultaneously. At the same time, through the sliding cooperation of the guide plate 29 and the guide groove 30, the movement of the moving block 8 can be guided and supported. When the sample placement is completed and the moving block 8 and the sample container move to the designated position inside the furnace tube 2, the positioning block 27 is released. Under the elastic recovery of the spring 26, the positioning block 25 rebounds and is inserted into the positioning groove to fix the position of the driving screw 14 and ensure the fixed measurement position of the moving block 8 and the sample container 10.

[0042] Embodiment 3

[0043] On the basis of Embodiments 1-2, in order to enable the sample container 10 to be stably arranged inside the backing plate 9, as Figures 1-2 and Figure 5 shown, a placement groove 20 is formed at the top of the backing plate 9. Two symmetrically arranged clamping plates 21 are slidably arranged on the inner wall of the placement groove. A driving groove is formed at the top of the backing plate 9. A sliding groove is communicated between the driving groove and the placement groove. The end of the clamping plate 21 passes through the sliding groove and is inserted into the driving groove. A bidirectional lead screw 22 is rotatably arranged in the driving groove. The clamping plate 21 is threadedly sleeved on the outer side of the bidirectional lead screw 22. The end of the bidirectional lead screw 22 passes through the backing plate 9 and is fixedly provided with a rotating block 23.

[0044] After the sample container 10 is placed inside the placement groove 20, the rotating block 23 can be driven, so that the bidirectional lead screw 22 drives the two clamping plates 21 to move. At this time, the two clamping plates 21 approach each other under the sliding limit of the sliding groove and clamp the sample container 10 to ensure the stable melting of the slag in the furnace tube 2 and ensure the measurement stability and measurement accuracy.
