Description

Technical Field

[0001] The invention relates to the technical field of titanium carbonitride production, and in particular to a device and a method for rapidly producing titanium carbonitride. Background Art

[0002] Titanium carbonitride is a metal compound, a titanium-based compound, usually composed of titanium, carbon and nitrogen. It is a common cemented carbide material, which is widely used in cutting tools, wear-resistant coatings and parts under high temperature and high pressure environments due to its excellent mechanical properties and chemical stability.

[0003] Common preparation methods for titanium carbonitride powder include solid phase method, gas phase method and liquid phase method. The most efficient of these methods is the solid phase method, which is to mix titanium and carbon powders, and then mix them with ammonia or nitrogen to prepare them at high temperature; however, in the prior art, the material and gas are mixed by filling the reactor with an ammonia or nitrogen atmosphere, and then fully stirring so that the material and gas can be fully mixed. However, this method makes the contact time between the material and the gas too short and the contact area with the gas is limited, which ultimately leads to poor mixing efficiency and even some materials are difficult to contact with the gas, resulting in a large difference in powder production rate, and ultimately the reaction time is forced to be extended.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] Example 1: Please refer to Figure 1-2 A device for rapidly producing titanium carbonitride comprises a reactor body 1, a storage cylinder 2 is arranged inside the reactor body 1, a heating mechanism is arranged inside the reactor body 1, a stirring component 3 and a nitrogen atmosphere control component 4 are arranged inside the reactor body 1, the stirring component 3 is used to mix and stir the raw materials, and the ammonia atmosphere control component is responsible for filling ammonia into the reactor and controlling the ammonia content.

[0040] Specifically, a controller is provided inside the reactor, and the heating mechanism is electrically connected to the controller to ensure that the heating mechanism maintains the material at a set reaction temperature.

[0041] A material leakage hole is provided at the bottom of the storage cylinder 2, and a material lifting component 5 is slidably connected between the reactor body 1 and the storage cylinder 2. The material lifting component 5 includes a sliding plate 51, and a feeding hole 52 is provided on the sliding plate 51. The inside of the feeding hole 52 is rotatably connected to a first rotating shaft 53, and a one-way plate 54 is fixedly connected to the outer end of the first rotating shaft 53. The inner wall of the feeding hole 52 is fixedly connected to a limit plate 55;

[0042] The chamber between the reactor body 1 and the storage cylinder 2 is divided into two upper and lower sections, namely the feeding area and the feed area. The ammonia atmosphere control component includes a two-way air pump 41. The two-way air pump 41 is located at the bottom of the feed area and is used to blow the material falling from the leakage hole to mix the ammonia with the material. The one-way plate 54 is in an open state near the feed area and in a closed state near the feeding area, so that the material mixed with the ammonia is transported to the inside of the storage cylinder 2.

[0043] See also Figure 3-5 A driving component 6 is provided on the material lifting component 5, and the driving component 6 includes a support plate 61 fixedly connected to the inner wall of the reactor body 1, a rotating hole is opened on the support plate 61, and a driven shaft 63 is rotatably connected to the rotating hole, and the end of the driven shaft 63 is rotatably connected to the inner wall of the reactor body 1, and the side end of the support plate 61 is rotatably connected to an arc-shaped rack plate 62, and a swivel 64 is fixedly connected between the sliding plate 51 and the rack plate 62, and the swivel 64 slides on the outer end of the support plate 61, and a driving gear 65 is fixedly sleeved on the driven shaft 63, and the driving gear 65 is meshed with the rack plate 62. When the driven shaft 63 rotates, the sliding plate 51 rotates accordingly.

[0044] Specifically, in this embodiment, the top of the storage cylinder 2 is open, a feed pipe and an air inlet pipe are provided on the top of the reactor body 1, and a storage box 10 is fixedly connected to the bottom of the reactor body 1.

[0045] Initially, after the reactor body 1 is evacuated by a vacuum pump, an inert gas such as argon (Ar) or helium (He) can be filled into the reactor according to demand, and then ammonia is filled into the reactor body 1. Ammonia contains nitrogen and hydrogen, which can provide a nitrogen source during the reaction process. At the same time, its reducing property helps to remove oxygen from titanium oxide (TiO2) and reduce unnecessary oxidation by-products. When using ammonia, the hydrogen content is relatively high, which can effectively avoid the occurrence of oxidation reactions.

[0046] Subsequently, the two-way air pump 41 is turned on. A pair of pipes 42 are provided on the two-way air pump 41. When one of the pipes 42 is in the blowing state, the other is in the suction state. The ends of the two pipes are detachably connected with filter screens to prevent materials from being sucked into the two-way air pump 41 during suction.

[0047] See also Fig. 9 A pair of partitions 43 are fixedly connected between the reactor body 1 and the storage cylinder 2, and the pipeline 42 is fixedly passed through one side of the partition 43. The partition 43 can prevent the material from entering the middle position of the bottom of the reactor body 1, and it is difficult to fall down later.

[0048] When the mixed material falls from the leakage hole, the two-way air pump 41 starts to blow air, and the airflow will fully mix and react with the falling material. At the same time, the driven shaft 63 will also drive the driving gear 65 to rotate, and the driving gear 65 will drive the rack plate 62 to rotate, so that the sliding plate 51 starts to rotate downward through the swivel 64, and the airflow breaks the one-way plate 54, so that the material and the gas pass through the feeding hole 52 and come to the top of the one-way plate 54; then the driven shaft 63 is rotated in the opposite direction to make the sliding plate 51 rotate upward, slowly conveying the material to the highest point, and falling parabolically into the top of the storage tube 2, and so on. The cycle is repeated, and the material on the top will eventually fall down and mix with the gas again, which prolongs the contact time between the material and the gas, and also makes the reaction complete, so that each part of the material can be fully and quickly mixed with the ammonia gas, which speeds up the reaction rate and improves the reaction efficiency.

[0049] The stirring component 3 includes a reduction motor 31 fixedly connected to the top of the reactor body 1 , the output end of the reduction motor 31 is fixedly connected to a driving shaft 32 , and the outer end of the driving shaft 32 is fixedly connected to a stirring rod 33 .

[0050] A first bevel gear 66 is fixedly sleeved on the outer end of the driving shaft 32 , and a second bevel gear 67 is fixedly sleeved on the end of the driven shaft 63 . The first bevel gear 66 and the second bevel gear 67 are meshingly connected.

[0051] The reduction motor 31 is turned on and electrically connected to the controller to control its forward and reverse rotation. When it rotates forward, it drives the drive shaft 32 to rotate. When the drive shaft 32 passes through the first bevel gear 66 and the second bevel gear 67, the driven shaft 63 rotates, so that the sliding plate 51 can descend. When the sliding plate 51 descends to the lowest point, the reduction motor 31 is controlled to reverse and the sliding plate 51 rises, thereby realizing the reciprocating up and down rotation of the sliding plate 51, intermittently lifting the mixed gas material to the top of the storage cylinder 2, and completing the full mixing of the material and the gas.

[0052] In an embodiment further provided by the present invention, a dredging component 7 is provided on the leakage hole, and the dredging component 7 includes a dredging plate 71 slidably connected to the inside of the leakage hole, the dredging plate 71 is an L-shaped structure, and an arc-shaped baffle plate 72 is fixedly connected to the dredging plate 71. During the up and down movement of the dredging plate 71 and the arc plate, the material in the leakage hole intermittently falls.

[0053] Since the material is heated during the reaction process, part of the material may become soft and have a certain elasticity. Therefore, when the material falls, a dredging plate 71 needs to be set. The dredging plate 71 is provided with an arc plate, which can not only block the material above when the dredging plate 71 falls, but also effectively slide the material down to one side of the dredging plate 71 under the action of the arc surface, so that when the dredging plate 71 rises, it automatically slides on the dredging plate 71, and finally not only completes the dredging of the leakage hole, but also accelerates the falling of the material.

[0054] See also Figure 6-7 In an embodiment further provided by the present invention, a throwing component 8 is provided on the dredging component 7, and the throwing component 8 includes a sealing plate 81 slidably connected to the outer end of the dredging plate 71, and a fixing plate 82 is slidably connected to the sealing plate 81. An elastic member 83 is fixedly connected between the sealing plate 81 and the dredging plate 71, and a wedge block 84 is fixedly connected to the side end of the sealing plate 81. The inclined surface of the wedge block 84 contacts the inner wall of the leakage hole. When the dredging plate 71 falls, the sealing plate 81 is quickly moved by the elastic member 83 to throw the material out.

[0055] Specifically, the elastic member 83 includes a telescopic tube 831, on which a return spring 832 is sleeved. The purpose of the return spring 832 is that when the dredging plate 71 is in the material leakage hole, it is in a contracted state and enters a power storage mode; when the dredging plate 71 moves downward, under the action of the return spring 832, the sealing plate 81 is pushed, and the material on its side is pushed out, so that the material can be thrown out in a parabolic state. The dispersion degree of the falling material is improved, the material and the ammonia are fully mixed, and the effect of mixing the material and the gas is improved.

[0056] See also Figure 8 In the solution further provided by the present invention, a reciprocating component 9 is arranged on the throwing component 8, and the reciprocating component 9 includes a protective tube 91 fixedly connected to the bottom of the storage tube 2, and a bidirectional screw rod 92 is arranged inside the protective tube 91. The bottom of the driving shaft 32 movably penetrates into the interior of the protective tube 91 and is fixedly connected to the bidirectional screw rod 92. The outer end of the bidirectional screw rod 92 is threadedly sleeved with a movable sleeve 93, and the outer end of the dredging plate 71 is fixedly connected with a driving rod 94. The end of the driving rod 94 is provided with a first electromagnet, and the first electromagnet is initially magnetically connected to the movable sleeve 93.

[0057] The outer end of the protective tube 91 is provided with a movable groove 95, and the outer end of the driving rod 94 is fixedly sleeved with a protective plate 96, which slides on the inner wall of the protective tube 91 and is responsible for blocking the movable groove 95 when the driving rod 94 moves.

[0058] Specifically, a boss is disposed on the outside of the protective tube 91 , and the boss will wrap the protective tube 91 so that the material is located on the boss, thereby preventing the material from being accumulated at the bottom all the time.

[0059] Turn on the reduction motor 31, the reduction motor 31 drives the driving shaft 32 to rotate, and the bidirectional screw 92 rotates accordingly, driving the external movable sleeve 93 to reciprocate up and down, thereby driving the dredging plate 71 to dredge the leakage hole up and down. In actual use, the stirring rod 33 can be selected to stir and rotate the material for a period of time. After the set time is reached, the first electromagnet can be turned on so that the first electromagnet can move the dredging plate 71 through the driving rod 94.

[0060] See also Fig. 9 A discharge component 11 located inside the storage box 10 is also provided at the bottom of the reactor body 1. The discharge component 11 includes a fixed base 111. The top of the fixed base 111 is inclined and fixedly connected to a hydraulic cylinder 112. A blocking plate 113 is fixedly connected to the top of the hydraulic cylinder 112. A discharge port is opened at the bottom of the reactor body 1, and the blocking plate 113 slides on the discharge port.

[0061] When the material and the gas are mixed, the two-way air pump 41 can be closed and the hydraulic cylinder 112 can be opened to drop the obtained material into the storage box 10. The blocking plate 113 is arranged in an inclined manner to facilitate the falling of the material.

[0062] Embodiment 2: Embodiment 2 differs from Embodiment 1 in that the following technical features are added:

[0063] See also Fig.10 In this embodiment, a pair of dredging components 7 and material throwing components 8 are provided, and another set of dredging components 7 and material throwing components 8 have the same structure as those in the first embodiment and are symmetrically positioned.

[0064] Specifically, in this embodiment, another set of material lifting components 5 is provided, and the structure is the same as that of the first embodiment.

[0065] What is different from the first embodiment is that the sliding plate 51 and the support plate 61 in this embodiment are magnetically connected, specifically: the side end of the sliding plate 51 is fixedly connected to the second electromagnet, and the support plate 61 is embedded with an iron block. When it is necessary to clear the material on the right side, the first electromagnet and the second electromagnet on the left side can be disconnected first, and after the rack plate 62 rotates to the right side, the second electromagnet and the first electromagnet on the right side can be turned on.

[0066] When the reaction runs to the set time, for example: 10-40 minutes, it can be adjusted according to needs. The pair of pipes of the two-way air pump 41 can be put into the opposite state. In the embodiment, the left side is in the blowing state and the right side is in the suction state; then in this embodiment, the left side is in the suction state and the right side is in the blowing state. At the same time, the rack plate 62 is adjusted to the right position through the controller, and the same operation as in Example 1 is performed again.

[0067] In this way, the filter will not be blocked and the purpose of automatic cleaning can be achieved.

[0068] A method for rapidly producing titanium carbonitride comprises the following steps:

[0069] Turn on the reduction motor 31, which is electrically connected to the controller to control its forward and reverse rotation. When the mixed material falls from the leakage hole, the two-way air pump 41 starts to blow air, and the airflow will fully mix and react with the falling material. At the same time, the driven shaft 63 will also rotate with the driving gear 65, and the driving gear 65 will rotate with the rack plate 62, so that the sliding plate 51 starts to rotate downward through the rotating ring 64, and the airflow breaks open the one-way plate 54, so that the material and gas pass through the feeding hole 52 and come to the top of the one-way plate 54; then the driven shaft 63 is rotated in the opposite direction to rotate the sliding plate 51 upward, slowly conveying the material to the highest point, and falling parabolically above the storage tube 2.

[0070] When the material falls, the dredging plate 71 moves up and down. When the dredging plate 71 is located at the upper part, it can not only block the material above, but also effectively make the material slide down to the side of the dredging plate 71 under the action of the arc surface, so that when the dredging plate 71 rises, it automatically slides on the dredging plate 71. When the dredging plate 71 is located at the lower part, the leakage hole can be dredged.

[0071] Moreover, when the dredging plate 71 moves downward, the sealing plate 81 is thrusted by the return spring 832, and the material on its side is pushed out forcefully, so that the material can be thrown out in a parabolic state, thereby improving the dispersion of the falling material and allowing the material to be fully mixed with the ammonia.

[0072] When the reaction runs to the set time, a pair of pipes of the two-way air pump 41 can be put into the opposite working state. Through the controller, when it is necessary to dredge the material on the right side, the first electromagnet and the second electromagnet on the left side can be disconnected first. After the rack plate 62 rotates to the right side, the second electromagnet and the first electromagnet on the right side can be turned on, so that the sliding plate 51 on the right side starts to work reciprocatingly.

[0073] When the material and the gas are mixed, the two-way air pump 41 can be closed and the hydraulic cylinder 112 can be opened to drop the obtained material into the storage box 10. Since the blocking plate 113 is arranged in an inclined manner, it is convenient for the material to fall.

[0074] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
