Description

Technical Field

[0001] The utility model relates to the technical field of ilmenite reduction, in particular to an ilmenite reduction device capable of automatically adding a reducing agent. Background Art

[0002] There are two methods for smelting ilmenite: sulfuric acid method and chlorination method. The two methods differ only in the treatment of titanium ore: sulfuric acid method can use lower-grade ilmenite ore, and can also make the cost of producing ferrous sulfate low, but it is too polluting, the by-products are difficult to handle, and it consumes a lot of sulfuric acid; the chlorination method uses higher-grade ore and higher costs, but it is less polluting, has fewer by-products, and chlorine can be recycled. However, both methods convert titanium ore into pure titanium dioxide, and then react pure titanium dioxide with pure chlorine and coke at high temperature to generate titanium tetrachloride and carbon monoxide, which are reduced to sponge-like titanium metal with metal calcium, magnesium or sodium.

[0034] like Figure 1 As shown, the top of the first storage tank 15 is provided with an airbag rod 151 for pressing and squeezing the reducing agent, the liquid outlet of the airbag rod 151 is connected to the inside of the housing 1 through a release tube 152, and the liquid inlet of the airbag rod 151 is connected to the inside of the first storage tank 15;

[0035] like Figure 1 As shown, a shaft rod 153 is transversely provided on the top of the shell 1, and a second gear 154 is sleeved on the shaft rod 153 which is perpendicular to and meshes with the first gear 132. A support member for supporting the rotation of the shaft rod 153 is provided on the shell 1, and the support member is a support rod 156 which is sleeved with the shaft rod 153 for limited rotation. One end of the shaft rod 153 extends to above the first storage tank 15 and is provided with a cam 155 for intermittently squeezing the airbag rod 151 during rotation.

[0036] The working principle of the above-mentioned ilmenite reduction device with automatic addition of reducing agent is as follows: ilmenite powder is added into the housing 1 through the feed pipe 11. After the addition is completed, the motor 131 is turned on to make the stirring rod 13 stir the ilmenite powder at a uniform speed, and the first gear 132 on the stirring rod 13 drives the second gear 154 to rotate, so that the shaft rod 153 drives the cam 155 to rotate, and the cam 155 squeezes the airbag rod 151 every time it rotates one circle to quantitatively pass the reduced hydrogen in the first storage tank 15 into the housing 1;

[0037] Furthermore, according to the quality of the introduced ilmenite powder and the degree of reduction, the rotation speed of the motor 131 can be adjusted to control the number of squeezing times of the airbag rod 151, that is, to control the amount of reduced hydrogen introduced.

[0038] Example 2

[0039] This embodiment is different from Embodiment 1 in that Figure 3 to Figure 6As shown, the top of the shell 1 is provided with a second storage tank 16 for storing a solid reducing agent, i.e., coke, and the bottom of the second storage tank 16 is provided with six discharge holes 163 communicating with the inside of the shell 1, and the bottom of the second storage tank 16 is provided with a rotating plate 161, and the rotating plate 161 is provided with docking holes 169 that are rotatably docked with the six discharge holes 163 one by one, and the shell 1 is provided with a driving mechanism for driving the rotating plate 161 to rotate;

[0042] The working principle of this embodiment is different from that of the first embodiment in that when solid reducing agent needs to be added, the shaft rod 153 drives the driving rod 165 to rotate, thereby driving the hinge rod 164 to rotate, and then controlling the central axis 162 to reciprocate forward and reverse, so that the docking hole 169 and the discharge hole 163 are intermittently docked, so that the solid reducing agent falls into the shell 1 and is combined with hydrogen for reduction;

[0043] And according to the quality and reduction degree of the ilmenite introduced, the nut 167 can be loosened to adjust the socket position of the screw 166 and the slide rail 168, and then the nut 167 can be tightened to fix the screw 166 and adjust the rotation amplitude of the central axis 162, thereby adjusting the docking degree between the docking hole 169 and the discharge hole 163, thereby controlling the amount of solid reducing agent added.
