Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer toFigures 1-5 , the present utility model provides a technical solution: a sample burning device for detecting sulfur elements in gold ore, including a furnace body 1. An intake three-way pipe 2 is provided at the intake port of the furnace body 1, and an exhaust three-way pipe 7 is provided at the exhaust port of the furnace body 1. One pipe orifice of the intake three-way pipe 2 is communicated with one pipe orifice of the exhaust three-way pipe 7 through a circulation pipe group, and an oxygen detector 61 for detecting the oxygen concentration inside it is provided on the circulation pipe group, so that oxygen circulates in the circulation pipe group and the furnace body 1, without the need to supplement new oxygen. Whether the sample is fully burned can be determined by detecting the change of oxygen concentration through the oxygen detector 61.

[0020] Further, another pipe orifice of the intake three-way pipe 2 is connected to an oxygen inlet pipe 3, and an intake three-way valve 21 is provided on the intake three-way pipe 2, which is convenient for adjusting the flow direction of oxygen.

[0021] Further, another pipe orifice of the exhaust three-way pipe 7 is connected to an exhaust pipe 8, and an exhaust three-way valve 71 is provided on the exhaust three-way pipe 7. The other end of the exhaust pipe 8 leads into an electrolytic cell, so that the discharged gas completely enters the electrolytic cell for reaction.

[0022] Further, the circulation pipe group includes a circulation air pump 5, a circulation pipe 4 connected to the intake three-way pipe 2, and an outlet pipe 6 connected to the exhaust three-way pipe 7. The circulation pipe 4 is communicated with the intake port of the circulation air pump 5, and the outlet pipe 6 is communicated with the outlet port of the circulation air pump 5. The circulation air pump 5 can control the circulation of oxygen in the circulation pipe 4, the outlet pipe 6 and the furnace body 1.

[0023] Further, the oxygen detector 61 is installed on the outlet pipe 6 for detecting the oxygen concentration inside it. The oxygen detector 61 detects the oxygen concentration at the outlet pipe 6. When the oxygen concentration is stable and no longer changes, it indicates that the sample is completely burned.

[0024] The furnace body 1 is a furnace body commonly used in sulfur detectors in the prior art.

[0025] The furnace body 1, the oxygen detector 61, the circulation air pump 5, the intake three-way valve 21 and the exhaust three-way valve 71 used in the present utility model are all common electronic components in the prior art. Their working methods and circuit structures are all well-known technologies and will not be elaborated here. The furnace body 1, the oxygen detector 61, the circulation air pump 5, the intake three-way valve 21 and the exhaust three-way valve 71 are all electrically connected to the sulfur detector main unit.

[0026] When in use:

[0027] After putting the magnetic boat containing the sample into the furnace body 1, control the furnace body 1 to burn the sample. The steps of introducing oxygen during the burning process are as follows:

[0028] 1. Adjust the intake three-way valve 21 and the exhaust three-way pipe 7 so that the movement track of oxygen is as Figure 3As shown in the figure, oxygen enters the interior of the furnace body 1 through the oxygen inlet pipe 3 to assist in burning the sample;

[0029] 2. After burning the sample for a period of time, adjust the intake three-way valve 21 and the outlet three-way pipe 7, and turn on the circulation air pump 5 and the oxygen detector 61 so that the movement track of oxygen is as Figure 4 shown. Oxygen enters the circulation pipe 4, the outlet pipe 6 and the furnace body 1 in sequence from the oxygen inlet pipe 3. Then, close the oxygen inlet pipe 3 through the external valve to stop the entry of new oxygen. At this time, oxygen circulates in the circulation pipe 4, the outlet pipe 6 and the furnace body 1, and the oxygen detector 61 detects the oxygen concentration at the outlet pipe 6. When the oxygen concentration is stable and no longer changes, it indicates that the sample has completely burned;

[0030] 3. After the sample has completely burned, first adjust the intake three-way valve 21 and the outlet three-way pipe 7 so that the movement track of oxygen is as Figure 5 shown in a. At this time, oxygen enters the circulation pipe 4 and the outlet pipe 6, and discharges the gas in the circulation pipe 4 and the outlet pipe 6. The discharged gas enters the electrolytic cell through the exhaust pipe 8;

[0031] 31. Then adjust the intake three-way valve 21 and the outlet three-way pipe 7 so that the movement track of oxygen is as Figure 5 shown in b. At this time, oxygen enters the furnace body 1 and discharges the gas remaining from the previous burning in the furnace body 1. The discharged gas enters the electrolytic cell through the exhaust pipe 8.

[0032] By adopting this method, part of the oxygen can be recycled, and the gas generated by burning can be completely discharged into the electrolytic cell for detection.

[0033] The utility model can adjust the movement track of oxygen during the burning of the sample, so that oxygen circulates in the circulation pipe group and the furnace body, which can ensure the complete combustion of the sample while reducing the amount of oxygen introduced, improve the detection result, help accurately calculate the sulfur content in the gold ore, and can also reduce the amount of oxygen introduced. It has simple operation and is convenient to use.
