Background
In the production process of preparing the titanium-rich material by the electric furnace smelting method, a part of materials with fine particle sizes, namely titanium slag fine powder, can be produced in the crushing process of the titanium slag blocks. The fine powder has fine particle size (-160 meshes), high impurity content (CaO and SiO) 2 High content of the same) and the like, and cannot be used as raw materials for the production of the chlorination process. These fines are more and more stocked and are stacked in large quantities in the factory space, which on the one hand takes up more money and on the other hand increases the management costs, as well as being a serious waste of resources. How to recycle these fine powders is urgent.
The applicant has tried to adopt a method of granulating fine powder into normal titanium slag, but insufficient granulating strength affects the granularity of titanium slag, resulting in the quality of titanium slag being reduced and the titanium slag cannot be used as a raw material for the production of the chlorination process.

However, the patent returns the fine-fraction titanium-rich material to the furnace for temperature rising and remixing, so that the recovery cost is high, and the method is not suitable for large-scale recovery and utilization.

Detailed Description
The utility model provides a titanium slag fine powder recycling system, which is shown in figure 1 and comprises an electric furnace slag hole 1, a diversion trench 2, an operation platform 3 with a slag hole 4 and a slag basin 5, wherein one end of the diversion trench 2 is connected with the slag hole 1, the other end of the diversion trench is aligned with the slag hole 4 of the operation platform 3, and the slag basin 5 is positioned below the operation platform 3. After the electric furnace finishes smelting, the smelted high-temperature titanium slag liquid (the temperature is about 1650 ℃), flows out of a slag outlet of the electric furnace, flows along a diversion trench, flows downwards from a slag outlet of an operation platform to form a slag flow 6 which is collected in a slag basin 5, and slag discharging is finished. The operation platform 3 is used for workers to stand to operate slag discharging and other processes.
On the basis of the above, the recycling system provided by the utility model further comprises a titanium slag fine powder bin 7, a fine powder conveying device 8 and a powder gun 9 which are sequentially communicated, wherein a blowing opening 10 of the powder gun 9 is aligned with slag flow, titanium slag fine powder is blown to slag flow according to a proportion (about 5% of the weight of the high-temperature titanium slag liquid) in the process of flowing the high-temperature titanium slag liquid to a slag basin, and is uniformly mixed with the high-temperature titanium slag liquid, the titanium slag fine powder is melted by utilizing the heat of the high-temperature titanium slag liquid, and is bonded into a whole, and slag blocks are formed after cooling, and because the titanium slag fine powder is subjected to the high-temperature melting sintering process, the strength is increased, and therefore the slag blocks can be used as raw materials for production by a chlorination method after being crushed. The powder gun is aimed at slag flow blowing instead of the diversion trench or the slag basin, and is easy to adhere to the bottom and the side wall of the diversion trench after being melted if being aimed at the diversion trench blowing, so that the normal flow of high-temperature titanium slag liquid is affected, and the mixing uniformity with the slag liquid is affected if being aimed at the slag basin.
The blowing of the titanium slag fine powder can cause a large amount of dust to appear in the surrounding environment, so the recycling system provided by the utility model also comprises a dust cover and a dust removal fan connected with the dust cover; the dust cover covers the slag basin and the operation platform around the jetting opening, dust around the slag flow can be collected through the dust cover and the dust removing fan, and the influence on the environment is reduced.
In summary, the titanium slag fine powder recycling system provided by the utility model utilizes the heat of the high-temperature titanium slag liquid, and can improve the granularity of fine powder without relying on new energy media to provide heat as in the prior art, so as to obtain the raw material conforming to the production of the chlorination process. By using the system provided by the utility model, about 200 tons of titanium slag fine powder can be treated each month, the waste of resources is reduced, and meanwhile, the energy source is effectively saved and the production cost of titanium slag is reduced.
Preferably, the diversion trench is arranged obliquely downwards for facilitating the flow of the high-temperature titanium slag liquid.
Preferably, the powder gun is connected with a Roots blower 13, and the fine powder is blown outwards by wind power.
Preferably, the fine powder conveying device is a spiral conveying device, so that uniform conveying of solid powder is facilitated.
Preferably, the titanium slag fine powder recycling system further comprises a tractor 14 for conveying slag basins and a crushing device, wherein the crushing device is preferably a multi-stage roller mill crushing combined powder selecting system. When the amount of the materials in the slag basin is enough, the slag basin can be conveniently conveyed to a target position through the tractor, and then a new slag basin is replaced to continue slag tapping. After slag blocks are formed by cooling slag liquid in the slag basin, the slag blocks are crushed and screened through a multistage roller mill crushing and powder selecting system, so that raw materials meeting the production of a chlorination method are obtained, and the screened fine powder with insufficient granularity can be conveyed to the system for recycling.
The slag basin and the operation platform are kept at a proper distance, so that the fine powder has enough space to be sprayed on the slag flow, and the upper surface of the slag basin is preferably 50-100 cm away from the lower surface of the operation platform; the distance between the blowing opening and the upper surface of the slag basin is 20-40 cm.
