Description

Technical Field

[0001] The invention relates to the technical field of powder metallurgy production, in particular to a method for producing titanium hydride powder from titanium sponge fine powder. Background Art

[0002] Titanium powder refers to titanium metal particles with a size of less than 1mm. Its performance combines the common properties of titanium metal and powder. Currently common titanium powder production processes include molten salt electrolysis, hydrogenation and dehydrogenation, atomization, etc. Among them, titanium powder prepared by hydrogenation and dehydrogenation has become the most common titanium powder production method due to its highest cost-effectiveness. Its main production steps include first hydrogenating the raw materials, then crushing and screening, and finally dehydrogenating the titanium powder with qualified particle size under high temperature and high vacuum.

[0003] There are two problems with such a titanium powder production process. First, a certain proportion of high-density lumps exist in the raw material sponge titanium, and hydrogen penetration is slow, requiring repeated hydrogenation and crushing. Large particles are returned for hydrogenation and crushing again, and the hydrogenation efficiency is low. Sponge titanium, as the raw material, will inevitably produce titanium fine powder during the crushing production process. The low price of titanium fine powder affects the overall profit of the enterprise. Compared with commercially available sponge titanium particles, titanium fine powder has a larger specific surface area and is easier to hydrogenate into hydrogenated titanium powder, with higher preparation efficiency, thereby increasing the added value of titanium fine powder. In order to be able to more efficiently produce and process titanium fine powder into hydrogenated powder, a method for producing hydrogenated titanium powder from sponge titanium fine powder is needed. Summary of the invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a method for producing titanium hydride powder from sponge titanium fine powder to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides a method for producing titanium hydride powder from titanium sponge fine powder, which adopts a fluidized tower and a recovery mechanism arranged on the right side of the fluidized tower, and comprises the following steps:

[0006] S1. First, the raw material titanium fine powder is fed into the fluidized bed tower through the feeding mechanism for reaction. When the raw material passes through the feeding mechanism, it is preheated to 380 degrees by the preheating channel, and then fed to the upper side of the filtering mechanism inside the fluidized bed tower;

[0007] S2. After the preheated raw materials are fed into the fluidized bed, hydrogen heated to 400 degrees is fed into the fluidized bed through the air inlet channel. The hot hydrogen contacts and reacts with the hot titanium fine powder inside the fluidized bed;

[0008] S3. The titanium hydride powder generated after the reaction is completed is in a fluidized state with the injection of hydrogen in the fluidized tower. Since the density of the titanium hydride powder is less than that of the titanium powder, the flow rate of the gas injection is controlled to ensure that the titanium hydride powder generated by the reaction is located in the loose phase area on the upper side of the fluidized tower, while the titanium powder is located in the dense phase area on the lower side of the fluidized tower;

[0009] S4. The connecting pipe of the recovery mechanism is arranged at the hinged position of the loose phase area and the dense phase area on the upper side of the right side surface of the fluidized tower, so that the fluidized titanium hydride powder in the loose phase area can enter the cyclone with the hydrogen, and then the cyclone can separate the powder and the gas, and cool the titanium hydride powder at the same time;

[0010] S5. The gas separated by the cyclone is recovered through the recovery channel at the top of the cyclone and waits for the next use;

[0011] S6. The powder separated by the cyclone enters the discharge pipe and is blocked by the first valve. Then, the first valve is opened to allow the material to fall between the first valve and the second valve. Then, the first valve is closed and the second valve is opened to allow the material to fall smoothly into the collection box.

[0012] The above steps use a fluidized tower and a recovery mechanism to complete the method of producing titanium hydride powder from fine titanium powder;

[0013] The fluidizing tower comprises a fluidizing tower shell, a feeding mechanism installed at the lower end of the left surface of the fluidizing tower shell, an air inlet channel connected to the lower end of the fluidizing tower shell, and an air inlet valve arranged at the middle position outside the air inlet channel;

[0014] A feed inlet is provided at the lower end of the left side surface of the fluidized tower shell, a limiting mechanism is provided on the outside of the feed inlet, and a filtering mechanism is provided on the inside of the feed inlet;

[0015] The filtering mechanism comprises a filter screen, two supporting plates arranged at the front and rear sides of the lower surface of the filter screen, an auxiliary plate welded to the left side of the upper surface of the filter screen, and a magnet embedded at the lower end of the left side surface of the auxiliary plate.

[0016] As a further improvement of the technical solution, the limiting mechanism includes limiting grooves symmetrically arranged on both sides and connecting plates welded to the left ends of the two limiting grooves, and the cross-section of the limiting groove is an L-shaped structure.

[0017] As a further improvement of the present technical solution, the feeding mechanism includes a feeding pipe, a preheating channel welded to the right side of the feeding pipe, and a limiting ring welded to the right end of the outer surface of the preheating channel.

[0018] As a further improvement of the present technical solution, the recovery mechanism includes a cyclone, a discharge pipe installed at the lower end of the cyclone, and a collecting box installed at the lower end of the discharge pipe. A recovery channel is provided on the upper surface of the cyclone, a connecting pipe for communicating with the fluidized tower shell is installed on the left side of the upper end of the outer surface of the cyclone, a first valve is provided on the upper side of the outer surface of the discharge pipe, and a second valve is provided on the lower side of the outer surface of the discharge pipe.

[0019] As a further improvement of the present technical solution, a notch for placing the auxiliary plate is provided on the lower surface of the feed port close to the inner side of the fluidizing tower shell, an iron sheet is embedded in the notch, and the support plate is welded to the lower ends of the front and rear surfaces inside the fluidizing tower shell.

[0020] As a further improvement of the technical solution, the preheating channel has an isosceles trapezoidal structure that is wider on the right and narrower on the left in a top view, and an electric heater is embedded in the preheating channel.

[0021] As a further improvement of the present technical solution, the limiting ring is slidably connected to the inside of the limiting groove, the limiting ring and the side surface of the limiting groove are both provided with threaded holes with corresponding positions, and a sealing ring is provided between the contact surface of the limiting ring and the limiting groove.

[0022] As a further improvement of the present technical solution, the collecting box is in a sealed state and is filled with argon in a slightly positive pressure state. After the hot fine powder enters the fluidized tower shell and before the hydrogen is introduced, 400-degree argon is introduced into the fluidized tower shell through the air inlet channel.

[0023] As a further improvement of the present technical solution, the fine powder fed by the feeding mechanism is 0-5 mm titanium fine powder screened out during the sponge titanium crushing process, the molar ratio of the amount of titanium fine powder added to the amount of hydrogen added is 1.8-2.2, and the hydrogenation time of the titanium fine powder is 1-5 hours depending on the amount of titanium fine powder in the liquefied state.

[0024] As a further improvement of the technical solution, after the reaction inside the shell of the fluidized tower produces titanium hydride powder, titanium fine powder is added at a rate of 10 kg / h and hydrogen is added at a rate of 2.6 L / s.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The method for producing hydrogenated titanium powder from sponge titanium fine powder uses a fluidized tower to react titanium fine powder with hydrogen, thereby increasing the contact area between titanium fine powder and hydrogen and accelerating the hydrogenation reaction efficiency.

[0027] 2.

[0045] S3, the titanium hydride powder generated after the reaction is completed is in a fluidized state with the injection of hydrogen in the fluidizing tower 1. Since the density of the titanium hydride powder is less than that of the titanium powder, the flow rate of the gas injection is controlled to ensure that the titanium hydride powder generated by the reaction is located in the loose phase area on the upper side of the fluidizing tower 1, while the titanium powder is located in the dense phase area on the lower side of the fluidizing tower 1;
