Problems solved by technology

[0002] At present, the measurement of total iron in iron ore mainly adopts titanium trichloride-potassium dichromate volumetric method. Sodium tungstate indicator, titanium trichloride solution, potassium dichromate, sodium diphenylamine sulfonate indicator and potassium dichromate are currently transferred between various platforms in hand-held flasks. The solution is heated to boiling, and then the flask needs to be cooled. During this process, the flask needs to be transferred from the heating platform to other stations. It is inconvenient to hold it manually, the workload is large, and it is not safe and the detection efficiency is low.

Embodiment 1

[0041] refer to figure 1 , a rotary iron ore analysis device, including a rotary table, a fixed table 1 and a flask 3, a weighing platform 4, a cooling platform 6 and a heating platform 7 are arranged at intervals on the circumference of the rotary table, and the rotary table is fixed on the base 5 On the side, the flask 3 is placed on the weighing platform 4 of the rotary workbench, the fixed workbench 1 is horizontally fixed above the flask 3 through the support column 2, and the fixed workbench 1 is fixed with a plurality of reagent dropping bottles 8 containing titration reagents and a The sample box 9 for holding the iron ore sample, the lower opening of the reagent dropping bottle 8 and the sample box 9 are all located above the opening of the flask 3, and the fixed workbench 1 is also fixed with a flask clamping mechanism, which is tightened and closed. The flask 3 is lifted, the rotary table rotates one or more stations, and the flask clamping mechanism makes the flask...

Embodiment 2

[0068] refer to Figure 10, the left clamp arm 14 and the right clamp arm 15 are respectively sleeved with a plurality of free-rotating rings 24, the left clamp arm 14 and the right clamp arm 15 swing relatively, and are clamped on the upper side of the V-shaped bottleneck of the flask 3, the flask When the V-shaped neck of the bottle 3 is squeezed and slides upwards, the ring 24 rotates with the rise of the flask 3, preventing the large sliding friction force between the flask 3 and the left clamp arm 14 and the right clamp arm 15, reducing the Friction, making it easier for flask 3 to rise.

[0069] refer to Figure 11 , the upper opening of the reagent drop bottle 8 is sealed with a capsule 16. Even if there is a certain gap between the distribution shaft 18 and the reagent drop bottle 8 due to processing, the negative pressure produced by the capsule 16 can ensure that the reagent will not fall freely. It can fall from the dispensing groove 19, further ensuring the accur...

Embodiment 3

[0071] refer to Figure 12 , a cooling fan 28 is installed on the cooling platform 6 of the rotary table, and the flask 3 is placed on the upper side of the cooling fan 28. When cooling is required, the cooling fan 28 works to cool the solution in the flask 3 rapidly and improve detection efficiency. Other structures are with embodiment 1.

Abstract

The invention relates to a rotary iron ore analyzing device, which belongs to the field of chemical analysis equipment of iron ores. A weighing platform (4), a heating platform (7) and a cooling platform (6) are at least arranged at the periphery of a rotary workbench, wherein a flask (3) is placed on one platform of the rotary workbench; an arc-shaped left clamping arm (14) and an arc-shaped right clamping arm (15) are arranged at two sides of the flask (3) and are connected with a clamping arm driving mechanism; the clamping arm driving mechanism is used for driving the left clamping arm (14) and the right clamping arm (15) to swing oppositely so as to be tightly clamped and also used for lifting the flask (3) so as to enable the bottom of the flask (3) to be apart from the rotary workbench; a fixing workbench (1) is fixed above the flask (3); a plurality of reagent dropping bottles (8) in which different indicators are contained are fixed on the fixing workbench (1); the flask is always positioned below each reagent dropping bottle; and the flask does not need to be moved during the dropping of various reagents and the adding of water. The rotary iron ore analyzing device realizes improvement in analysis detection efficiency, and is high in degree of automation as well as safe and convenient to operate.
