Abstract

PURPOSE:To automate the device and to save manpower by grinding a sample, removing the metal component therefrom by a sieving machine and cleaning a sample grinding mill and sieving machine before handling the next sample. CONSTITUTION:The sample in a sample holder 1 is charged into a hopper 4 and is compressed and ground by a grinding rod 7 in a grinding vessel 6. The sample after the grinding is introduced into the sieving machine 13, where the metal component in the sample is removed. This sample is charged into a sample spoon 14. A washing water nozzle 2 and a compressed air nozzle 3 are disposed in a hopper 4. Washing and drying are executed by the water and air spouting operations thereof after the end of the sample treating operation. Further, the sieving machine 13 are cleaned by a compressed air nozzle 11. A controller 15 makes the sequence control of the operations of the respective devices mentioned above.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for removing metal components in the analysis of slag generated in iron-making furnaces and steel-making furnaces.

[Prior art] In recent years, as a component analysis method for iron ore, blast furnace slag, converter slag, electric furnace slag, etc., a flux is added to the sample and melted.
A method of analyzing the melt using a fluorescent X-ray analyzer has come into widespread use. This sample manufacturing process is divided into sample crushing → metal bone removal → weighing → melting material addition → melting → cooling → bead removal. Sodium borate or the like is used as the melting material, and melting is performed at 1050 to 1200°C using an electric furnace or the like. It is done by heating. Use a platinum crucible for melting, 0.5g
A glass bead is produced by melting the sample. We aim to obtain uniform samples by automating the above steps as much as possible. In Japanese Patent Application Laid-open No. 51-74689, steps after weighing in the above steps are automated, but sample crushing and metal removal are not automated.

[Problems to be Solved by the Invention] As mentioned above, complete automation of all processes has not been achieved in glass bead production. The object of the present invention is to solve the above-mentioned problems and to propose a fully automated metal removal device for slag analysis.

[Means for Solving the Problems] The metal removal device for slag analysis according to the present invention has a sample crusher, a sieve machine, and a spoon as main components, and includes a fume gas used for cleaning the sample crusher and the sieve machine, This is a metal removal device for slag analysis, which is equipped with a fountain device and a control device to automatically perform these operations.

[Function] The metal content removal device for slag analysis in the present invention crushes the sample with a sample crusher, removes the metal content from the sample with a sieve machine, and removes the metal content from the sample with a jet or fountain device before applying it to the next sample. Clean the crusher and sieve machine.

[Embodiment] FIG. 1 is an explanatory diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing a time sequence of the present invention.

In Figure 1, the sample (approximately 5 to 1
0gr) is charged into the hopper 4, and by opening the charging stopper 5 disposed at the connection between the hopper and the grinding container 6, the sample is charged into the grinding container. The sample is compressed and crushed by the crushing container and the crushing rod 7 by driving the crushing container. After crushing, the sample is placed in the discharge stopper 8.
(by opening the opening diameter 5 to 10 degrees), the sample is introduced through the discharge shoe made of soft resin pipe 10 into the sieve 13 (60 mesh sieve) driven by an electromagnetic vibrator. The metal content inside is removed and the sample spoon 14 (capacity 0.5 to Igr) is loaded.

On the other hand, before the next sample reaches each device, they need to be cleaned.

A cleaning water nozzle 2 and a compressed air nozzle 3 are installed in the hopper.
It will be cleaned and dried using a fumarole process. At this time, the discharge chute is moved from the upper part of the sieving machine to the upper part of the exhaust/drainage chute 12 by a discharge chute moving device 9 driven by a hydraulic drive. Fountain, hopper by fumarole work,
The input stopper, grinding container, grinding rod, discharge stopper, and discharge chute are cleaned. Further, the sieving machine is cleaned by a compressed air nozzle 11. In order to sequentially control the operations of the above-mentioned devices by the controller 15, signals from the controller are issued as shown in FIG. In FIG. 2, A is the sample holder 1, B is the input stopper 5, C is the crushing container 6, D is the discharge stopper 8, E is the discharge chute moving device 9, F is the sieving device 13, and G
indicates the sample spoon 14, H indicates the compressed air nozzle 3, ■ indicates the compressed air nozzle 11, and J indicates the controller 1 of the cleaning water nozzle 2.
This is an operation command signal based on 5.

In FIG. 2, the sample holder 1 is reversed (sample is loaded) at a, and returned to its original position at b. The input stopper 5 opens at a for sample input, closes at b, opens at C for cleaning, and closes at d. The crusher starts at step a and stops after crushing the sample and cleaning the equipment. The discharge stopper 8 opens at a after the grinding is finished, and closes after the washing is finished. After the discharge is completed, the discharge chute 10 moves to the upper part of the exhaust/drainage chute 12 at a, and returns to the upper part of the sieving machine 13 at b. The sieving machine 13 starts sieving by vibration at a, stops at b, reverses at C to remove metals, and returns to its original position at d. The sample spoon 14 starts moving at a, moves onto a crucible (not shown) at b, turns over at C and puts the sample into the crucible, returns at d, starts moving at e, and moves at f. Return to original position. After the compressed air nozzle 3 finishes spouting the cleaning water, it starts blowing at a point,
End with b. The compressed air nozzle 11 starts moving at a, moves to the top of the sieving machine 13 at b, starts blowing at C, and d
End with "e", start moving with "e", and return to the original position with "f". After the pulverization is completed, the cleaning water nozzle 2 starts spouting water at point a and ends at point b.

[Effects of the Invention] As described above, according to the present invention, by automating the metal removal device in slag analysis, labor can be saved and a uniform sample can be obtained.
