Description

Technical Field

[0001] The invention relates to the technical field of impurity removal of titanium sponge products, and in particular to an air separation device for removing impurities from titanium sponge products. Background Art

[0002] Sponge titanium is a sponge-like titanium produced by the metallothermic reduction method. It is the main raw material for making industrial titanium alloys. It is divided into five grades from WHTiO to MHTi4 according to the purity. Sponge titanium production is the basic link of the titanium industry. It is the raw material for titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, put it in a sealed stainless steel tank, fill it with argon gas, and react with magnesium metal to obtain "sponge titanium". This porous "sponge titanium" cannot be used directly, and it must be melted into liquid in an electric furnace before it can be cast into titanium ingots.

[0003] Application No. CN218691582U discloses a rice winnowing machine, comprising a feed hopper, a winnowing box, a bellows and a discharge hopper, wherein the feed hopper is arranged at the top of the winnowing box and is connected to the winnowing box, one end of the winnowing box is connected to the bellows, the other end of the winnowing box is provided with an exhaust port, the discharge hopper is arranged at the bottom of the winnowing box and is connected to the winnowing box, a feed regulating part for regulating the feed flow rate is provided at the bottom of the feed hopper, an impurity separation device for separating rice from impurities is provided in the winnowing box, the feed regulating part is connected to the impurity separation device through a downwardly inclined slide, the density of rice falling is reduced by adjusting the feed flow rate of rice, and it is ensured that dust, husks, rice stalks and leaves and other debris in the rice are fully separated from the rice, and heavy debris such as stones or clods of earth mixed in the rice are separated by the impurity separation device, so as to further reduce impurities in the rice, the winnowing efficiency is high, the winnowing effect is good, and the structure is simple and ingenious.

[0004] Since sponge titanium is easily stuck to the leather on the conveyor belt during production and transportation, and sponge titanium still contains some high-iron materials, the purity of the titanium element product is not high enough, thus affecting the product quality. When the existing air separator is used to select sponge titanium, the sponge titanium must slide in the curved air duct to allow a longer air selection time, resulting in the efficiency of air selection and material collection being not high enough, slowing down the subsequent processing time of sponge titanium, especially the coarse material.

The upper conductor 470 for parallel connection of the upper end of the spiral conductor 4211 is embedded in the lower conductor 46, and an upper contact 4701 electrically connected to the upper conductor 470 is arranged on the bottom surface of the gasket ring 411; the lower conductor 46 also includes a lower parallel bar 461 embedded in the lower conductor 461 and a lower connecting bar 462 connecting the lower parallel bar 461 and one of the poles of the battery 48; the upper conductor 47 also includes an upper parallel bar 471 for parallel connection and an upper connecting bar 472 connecting the upper parallel bar 471 and the other pole of the battery 48;

[0057] Working principle of the present invention:

[0058] The fan 320 and the vibration motor 2010 are started by the supporting controller, and the sponge titanium material to be processed is put into the vibrating screen feed box. The vibration motor 2010 drives the vibrating screen mesh 201 to vibrate, and the sponge titanium material is initially screened. The upper part of the sponge titanium material enters the material drop pipe 31 through the material discharge pipe 22. The fan 320 blows air along the Z-shaped air duct 32. The heaviest coarse material part will not be affected by the wind, and thus directly falls vertically along the material drop pipe 31 into the coarse material collection In the storage box 30, the high-speed air duct 321 closest to the fan 320 blows the heavier flakes into the flake storage barrel 33, and then the high-speed air duct 321 is connected to the medium-speed air duct 322. Since it is farther away from the fan 320, the wind speed is reduced and only the fine flakes can be blown into the fine flake storage barrel 34. Finally, the medium-speed air duct 322 is connected to the low-speed air duct 323 farthest from the fan 320. The low-speed air duct 323 blows the finest titanium sponge material and leather impurities including those stuck to the conveyor belt into the filter sack 35;

[0059] The sponge titanium material that has been partially screened by the vibrating screen mesh 201 enters the screened material discharge pipe 40, and is adsorbed by the magnetic rod 42 that is slidably inserted therein to contain the iron-containing high-iron material, while the sponge titanium material that does not contain iron continues to slide obliquely downward into the iron-removing material storage box 401. If it is necessary to collect the adsorbed high-iron material on the magnetic rod 42, the electric cylinder 45 is controlled by the matching controller to extend the air rod 450 to the highest point, and the upper contact 4701 is electrically connected to the upper end of the spiral conductor 4211, and the lower parallel bar 461 is electrically connected to the lower end of the spiral conductor 4211. When the current from the battery 48 is turned on, a magnetic field is formed at the spiral conductor 4211 that offsets the magnetic rod 42, thereby causing the high-iron material on the magnetic rod 42 to fall off and enter the high-iron material storage box 41.

[0060] In addition, it should be noted that the components involved in the present invention, such as the vibration motor 2010, the fan 320, the battery 48, the spiral wire 4211, the lower wire 460, the upper wire 470 and the controller, are all universal standard parts or components known to the technical personnel in this field, and their structures and principles are all known to the technical personnel in this field through technical manuals or through conventional experimental methods.
