Example Embodiment

[0035] In the first embodiment, various types of iron-containing waste Y0 are four kinds of iron-containing waste materials, which are steelmaking sludge, desulfurization slag, gravity ash, and dust ash. After testing, the iron content of various iron-containing waste Y0 is 50% iron content in steelmaking sludge, 50% iron content in desulfurization slag, 20% iron content in gravity ash, and approximately 35% iron content in dust removal ash.

[0036] In step S12, the flow setting device 2 determines the batching flow of various iron-containing waste materials Y0 according to the iron content of the various iron-containing waste materials Y0 and the iron content of the vanadium-titanium smelting raw material Y1.

[0037] The batching flow rate of the various types of iron-containing waste Y0 refers to the batching flow rate corresponding to each of two or more unmixed iron-containing waste materials. In combination with Example 1, according to the production requirements, the iron content of the vanadium-titanium smelting raw material Y1 is about 40%, so the following batching flow plan can be determined: the flow rate of steelmaking sludge and desulfurization slag is 135 tons/hour, and gravity ash The flow rate is 75 tons/hour, and the dust removal ash flow rate is 90 tons/hour. The total iron-containing waste per hour is 435 tons, the total iron content is 181.5 tons, and the total iron content is 41.72%, which meets the production requirements. It should be pointed out that the batching flow plan takes into account the working capacity of the pre-mixing device 3, and other batching flow plans can also be determined within the allowable range of the working capacity of the pre-mixing device 3.

[0038] In step S13, the pre-mixing device 3 transports various iron-containing waste materials Y0 together according to the batching flow rate of various iron-containing waste materials Y0 to obtain pre-mixed raw materials.

[0039] In step S14, the stacking equipment 4 stacks the premixed raw materials in layers to obtain the vanadium-titanium smelting raw material Y1.

[0040] See image 3 , The second embodiment of the present invention provides a vanadium-titanium smelting raw material preparation device, including a detection device 1, a flow setting device 2, an electronic belt scale 30, a belt conveyor 31, and a stacker 40. See Figure 4 The working process of the vanadium-titanium smelting raw material preparation device is as follows:

[0041] In step S21, the detection device 1 detects the iron content of various iron-containing waste materials Y0.

[0042] In step S22, the flow setting device 2 determines the batching flow of various iron-containing waste materials Y0 according to the iron content of the various iron-containing waste materials Y0 and the iron content of the vanadium-titanium smelting raw material Y1.

[0043] In step S23, the electronic belt scale 30 transports various iron-containing waste materials Y0 to the belt conveyor 31 according to the batching flow rate of the various iron-containing waste materials Y0 to obtain pre-mixed raw materials.

[0044] The number of the electronic belt weigher 30 is determined according to the type and quantity of the iron-containing scrap Y0 in each type of iron-containing scrap Y0. For example, in the second embodiment, various types of iron-containing waste Y0 are steel-making sludge, desulfurization slag, gravity ash, and dust removal ash, a total of 4 types of iron-containing waste materials, so the number of electronic belt scales 30 is an integral multiple of 4, such as 4 Or 8. It should be pointed out that when the multiple is greater than 1, in order to facilitate uniform mixing, the electronic belt scales 30 are periodically arranged according to the types of iron-containing wastes, that is, the number of electronic belt scales for conveying the same type of electronic belt scales 30 is the same.

[0045] The number of electronic belt scales 30 can also be determined according to the number of different flow values in the batching flow of various iron-containing waste Y0. For example, in Example 2, the iron content of various types of iron-containing waste Y0 is 50% iron content in steelmaking sludge, 50% iron content in desulfurization slag, 20% iron content in gravity ash, and approximately 35 percent iron in dust removal ash. %. According to the production requirements, the iron content of the vanadium-titanium smelting raw material Y1 is about 40%. The following batching flow plans are determined: steelmaking sludge is 135 tons/hour, desulfurization slag flow is 135 tons/hour, and gravity ash flow is 75 tons/hour, the dust removal ash flow rate is 90 tons/hour, and there are 3 different flow values. Therefore, the number of electronic belt scales 30 is an integral multiple of 3, such as 3 or 6. It should be pointed out that when the batching flow values of two or more iron-containing wastes are similar, they can also be treated as the same flow value if the production requirements are met, and then use the above method to determine the number of electronic belt scales 30 , The principle is the same.

[0046] The number of belt conveyors 31 is determined according to site layout requirements, and is generally 2 to 4. The function of the belt conveyor 31 is to collect all kinds of iron-containing waste Y0 conveyed by the electronic belt scale 30 to obtain and transport the premixed raw materials. The specific method can be: all the belt conveyors 31 are connected in series to form a transportation line, and the electronic belt scale 30 conveys various types Belt conveyor 31 for ferrous waste Y0 to the starting position of the transportation line.

[0047] In step S24, the stacker 40 stacks the pre-mixed raw materials in layers to obtain the vanadium-titanium smelting raw material Y1.

[0048] The number of stackers 40 is determined according to site layout requirements, and is generally one or two. The stacker 40 obtains the pre-mixed raw materials from the belt conveyor 31 and stacks them in layers. Specifically, the layer stacking operation can be performed in a linear reciprocating manner.

[0049] See Figure 5 , The third embodiment of the present invention provides a vanadium-titanium smelting raw material preparation device, including a detection device 1, a flow setting device 2, an electronic belt scale 30, a belt conveyor 31, a stacker 40 and a mobile silo 5. In the third embodiment, a mobile silo 5 is added on the basis of the second embodiment. The working principles of other parts are the same as those in the second embodiment. For details, please refer to the description in the second embodiment and will not be repeated.

[0050] The number of mobile silos 5 is determined according to the number of electronic belt scales 30. Each mobile silo 5 has a corresponding electronic belt scale 30. The mobile silo 5 is responsible for loading various ferrous waste Y0 and supplying it to the electronic belt scale 30. The specific method may be: after the mobile bin 5 is loaded with the iron-containing waste to be conveyed by the electronic belt scale 30, it is moved to the top of the electronic belt scale 30, and the material is discharged by gravity.

[0051] See Image 6 , Which is a preferred equipment layout scheme of the third embodiment of the present invention, the scheme is provided with 10 electronic belt scales 30, 10 mobile silos 5, 3 belt conveyors 31 and 1 stacker 40. Of course, the number of the electronic belt scale 30 and the mobile bin 5 in the solution can be other values according to actual production conditions.
