[0021] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0022] The utility model provides a kind of alloy liquid slag content detection device, including crucible 1, the bottom of crucible 1 is tapered, to be more convenient for alloy liquid to flow down, the bottom of crucible 1 is equipped with liquid outlet, and on-off valve 2 is connected on liquid outlet by bolt, on-off valve 2 selects electromagnetic valve, and on-off valve 2 is detachably connected with liquid outlet.

[0023] The end of on-off valve 2 away from crucible 1 is communicated with negative pressure cylinder 3, and negative pressure cylinder 3 includes cylinder body 31 and cylinder cover 32, and cylinder body 31 is sealingly matched with cylinder cover 32, and on-off valve 2 is communicated with cylinder cover 32 by pipeline. Negative pressure pump 4 is also communicated with cylinder cover 32, and negative pressure pump 4 can extract negative pressure cylinder 3 to negative pressure state.

[0024] Crucible 1 is internally provided with filter screen 12, and filter screen 12 selects micro ceramic filter screen, and filter screen 12 is arranged at the position of the bottom of crucible 1 being tapered, and filter screen 12 is arranged above liquid outlet, to filter alloy liquid in crucible 1, so that slag in alloy liquid is filtered out.

[0025] Mass sensor 6 is also installed below cylinder body 31 of negative pressure cylinder 3, to detect the mass of negative pressure cylinder 3. The utility model further includes fixing frame 5, and fixing frame 5 includes fixed bottom plate 51, and bottom plate 51 is arranged below mass sensor 6, so that mass sensor 6 can be placed on bottom plate 51, and support rod 52 is welded on bottom plate 51, and support rod 52 is vertically arranged, and support rod 52 is arranged outside negative pressure cylinder 3 and is arranged in parallel with the central axis of negative pressure cylinder 3.

[0026] Pull ring 53 is welded on the side wall of support rod 52, and pull ring 53 is arranged perpendicular to support rod 52, and pull ring 53 is coaxially arranged with negative pressure cylinder 3, and the upper end of crucible 1 is provided with outer flange 11 matched with pull ring 53, to be clamped with pull ring 53, so that crucible 1 can be fixedly arranged above negative pressure cylinder 3.

[0027] The electromagnetic sensor 13 is embedded in the sidewall of the crucible 1 and is arranged below the filter screen 12. The electromagnetic sensor 13 can detect the alloy liquid flowing through the filter screen 12. Since the slag and the alloy liquid have different conductivities, if the alloy liquid contains slag, the electromagnetic sensor 13 can output an electric frequency signal.

[0028] The output end of the electromagnetic sensor 13 and the mass sensor 6 is electrically connected with a control system 7. The control system 7 is a PLC programmed controller. The electromagnetic sensor 13 and the mass sensor 6 can output an electric frequency signal to the control system 7.

The control system 7 can output a display signal to the display screen 71 based on the electric frequency signal output by the electromagnetic sensor 13 and the mass sensor 6, so as to make feedback on the display screen 71.

[0029] Detection process: first, close the electromagnetic valve and open the negative pressure pump 4 to draw the negative pressure cylinder 3 to a negative pressure state.

[0030] Secondly, a certain mass of alloy liquid is injected into the crucible 1, and then the electromagnetic valve is opened to connect the negative pressure cylinder 3 with the crucible 1. Since the negative pressure cylinder 3 is in a negative pressure state, a certain pressure difference is formed between the negative pressure cylinder 3 and the crucible 1, so that the alloy liquid is squeezed into the negative pressure cylinder 3. In the process of being squeezed into the negative pressure cylinder 3, the alloy liquid is filtered by the filter screen 12, and the slag is filtered out. The filtered alloy liquid is detected by the electromagnetic sensor 13. If there is still slag, the display screen 71 will react.

[0031] Finally, after the alloy liquid in the crucible 1 flows into the negative pressure cylinder 3, the mass sensor 6 can detect the specific mass of the alloy liquid in the negative pressure cylinder 3, and then compare the mass value detected by the mass sensor 6 with the mass of the alloy liquid initially injected into the crucible 1, so as to obtain the amount of filtered slag and calculate the slag content in the alloy liquid. The calculation formula is as follows:

[0032]

[0033] Wherein, W is the slag rate, W0 is the mass of the alloy liquid injected into the crucible 1, and W1 is the mass of the alloy liquid filtered into the negative pressure cylinder 3.

[0034] In summary, the utility model discloses a filter screen 12 can filter out the slag in alloy liquid, and the quality of alloy liquid after filtering is detected through quality sensor 6, can obtain the quality of slag filtering out, and further obtain the slag content in alloy liquid.
