Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary equipment for sponge titanium production, and specifically relates to an automatic rust removal, pickling and titanium infiltration device and application thereof. Background Art

[0002] Titanium and titanium alloys are high-quality structural materials with the characteristics of light weight, high specific strength, good corrosion resistance, and excellent high and low temperature performance. They are widely used in aviation, aerospace, ocean, electricity, chemical industry, metallurgy, light industry, energy, environmental protection and other fields. In the production of sponge titanium, most of the large domestic titanium smelting enterprises adopt the process of magnesium reduction to prepare sponge titanium, among which the integrated reduction and distillation process realizes the closed-loop circulation of the raw material Mg-Cl2-MgCl2.

[0003] The reduction process with liquid magnesium is widely used in magnesium-titanium joint enterprises because it can save heat energy, shorten the reduction cycle and improve productivity. In the reduction process of this process, titanium tetrachloride and liquid magnesium are added to the reduction reactor to react to generate titanium and magnesium chloride, and the magnesium chloride is discharged through the guide pipe and the discharge pipe. In the distillation process, the reduction reactor (also serving as a distillation reactor) is connected to the channel heater. It can be connected before reduction or while hot after the reduction is completed. During the distillation process, the magnesium and magnesium chloride that are not discharged are distilled into the distillation reactor through the channel heater for the next reduction.

[0004] However, there are many problems that need to be solved in the actual use of the reactor. When the reactor is used for the first time, there is a lot of rust and foreign matter on the outer surface of the reactor after manufacturing. In the continuous high temperature environment of titanium production, the rust on the outside of the reactor is affected by water vapor and on-site chloride ions, and it is very easy to corrode. This will not only seriously affect the service life of the reactor, but also if the oxide scale falls into the steaming furnace, it is easy to cause the furnace wire of the steaming furnace to be grounded, thereby affecting the service life of the steaming furnace. At present, before the reactor is put into use, it is necessary to manually grind and remove rust and pickle the outside of the reactor, and remove rust and titanium infiltrate the inside. However, due to the large surface area inside and outside the reactor, the manual rust removal, pickling and titanium infiltration work is huge, and there are high safety risks in the operation process. For example, the operator may suffer health damage due to long-term contact with rust removal and pickling chemicals, and there is also a risk of falling when working at heights. In addition, manual operation is difficult to ensure the uniformity of the quality of rust removal and pickling, which may lead to incomplete rust removal or excessive pickling in some areas, affecting the subsequent titanium infiltration effect and the overall performance of the reactor.

[0005] In view of this, this invention is proposed. Summary of the invention

[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] like Figures 1 to 5 As shown, the automatic rust removal, pickling and titanium infiltration device provided in the embodiment of the present invention is mainly used to process cylindrical reactors of different diameters. The device includes a support frame 1, which has the following two functions: one is to carry the horizontally placed reactor A to be processed, and provide a reliable support foundation for the reactor A; the second is to be able to drive the reactor A to rotate around its central axis at a uniform speed according to a preset speed, so as to ensure that in the subsequent processing process, all parts of the reactor A can be evenly treated. On one side of the opening of the reactor A, a lifting mechanism 2 is provided, and the movable end of the lifting mechanism 2 can reciprocate in the vertical direction. By controlling the position of the movable end, it is ensured that the equipment subsequently installed thereon can process the inner and outer surfaces of the reactor A. At the same time, it can be applicable to various types of reactors with different diameter specifications, which expands the scope of application of the device. A movable track 3 parallel to the axis of the reactor A is fixedly arranged on the movable end of the lifting mechanism 2, and a rust removal mechanism 4, a pickling mechanism 5 and a titanium infiltration mechanism 6 (of course, other mechanisms can also be used according to actual needs) that can be removably arranged on the movable track 3 to reciprocate along the track, so that different operating mechanisms can be selected and installed according to needs; wherein, the rust removal mechanism 4 is responsible for removing the rust on the inner and outer surfaces of the reactor A; the pickling mechanism 5 uses a specific acidic solution to further clean and activate the surface of the reactor A; the titanium infiltration mechanism 6 diffuses the titanium element to the inner surface of the reactor A, so that the reactor A forms a titanium infiltration layer with special properties. In addition, the device is also equipped with a PCL control system, which is connected to the support frame 1, the lifting mechanism 2, the movable track 3, the rust removal mechanism 4, the pickling mechanism 5 and the titanium infiltration mechanism 6 through electrical lines, and it coordinates the operation of each component through a pre-written program (existing technology, no longer detailed description), accurately adjusts the working order, working time and working parameters of each mechanism, and realizes the full process of automated rust removal, pickling and titanium infiltration operations on the reactor A, ensuring the stability and consistency of the treatment effect.

[0044] In the embodiment of the present invention, four sets of support frames 1 are specially designed to ensure stable support and uniform rotation of the cylindrical reactor A. The four sets of support frames 1 are symmetrically distributed on both sides of the bottom along the axial direction of the reactor A. This symmetrical distribution provides a more balanced support force for the reactor A, preventing tilting or instability during the treatment process.

[0045] Specifically, each support frame 1 includes a support shell 11 with an inclined surface, and a roller 12 is movably mounted on the inclined surface of the support shell 11. At the same time, a sixth drive motor and a fourth transmission component are arranged inside the support shell 11. Among them, the sixth drive motor is used as a driving source, and its selection is based on a comprehensive consideration of multiple factors such as the weight of the reactor A, the required rotation speed, and the actual workload. The sixth drive motor is connected to the PCL control system, and the PCL control system can accurately control the start, stop, speed, and steering of the sixth drive motor and other operating parameters; the fourth transmission component is an important component connecting the sixth drive motor and the roller 12, and a variety of transmission methods can be adopted (the transmission components in the present invention can be selected according to actual conditions), such as chain drive, belt drive or gear drive, etc. Taking chain drive as an example, a sprocket is installed on the output shaft of the sixth drive motor, and the power is transmitted to the movably mounted on the inclined surface of the support shell 11 through the chain. The advantages of this transmission method are simple structure, low cost, and the ability to withstand large loads to a certain extent; if gear transmission is adopted, the power is transmitted through the meshing gears, which can achieve a more accurate transmission ratio and higher transmission efficiency; and the belt transmission can play a certain buffering and shock absorbing role between the motor and the roller, and has the characteristics of stable operation; the roller 12 is a component that is in direct contact with the reactor A, and its surface is specially treated to have high hardness and good wear resistance to ensure that it will not be damaged by friction with the reactor A during long-term operation, and at the same time ensure good friction, so that the reactor A can stably rotate with the rotation of the roller 12. Through the above settings, when the sixth drive motor is started, the roller 12 starts to rotate through the transmission of the fourth transmission component, and then drives the reactor A to rotate circumferentially around its central axis according to the set speed and direction, providing reliable rotation conditions for subsequent rust removal, pickling and titanium infiltration processes.

[0046] In the embodiment of the present invention, the lifting mechanism 2 is mainly composed of a fixed platform 21 (a roller with a brake can be provided at the bottom of the fixed platform to facilitate the movement of the entire lifting mechanism 2; or when the position of the lifting mechanism 2 is fixed, the mobile platform 3 is located inside or outside the reactor A by adjusting its height and the position of the reactor A), a seventh drive motor, a screw 22, a linear guide 23 and a screw nut 24. Among them, the seventh drive motor is installed in the fixed platform 21 and connected to the PCL control system, and its output shaft is connected to the screw 22 vertically arranged on one side of the fixed platform 21 through a coupling, and the screw nut 24 is screwed on the screw 22 and slidably connected to the linear guide 23 parallel to the screw 22. At the same time, the screw nut 24 is fixedly connected to the moving track 3. In order to ensure the reliability of the connection between the moving track 3 and the screw nut 24, it is preferred to set a reinforcing rib between the two, so as to form a stable lifting mechanism, which can realize accurate vertical lifting movement to meet the processing requirements of different height positions of the reactor.

[0047] In the embodiment of the present invention, in order to ensure the safety of the rust removal mechanism 4, the pickling mechanism 5 and the titanium infiltration mechanism 6 running on the moving track 3, a set of anti-collision limit mechanism 7 is specially set at both ends of the moving track 3. Each set of anti-collision limit mechanism 7 is mainly composed of the following parts: First, the limit block 71 is made of metal material and can withstand a certain impact force. Its main function is to physically block the mechanism that may exceed the range of the moving track 3 to prevent them from derailing or colliding with other components; second, a proximity sensor 72 connected to the PCL control system is installed near the limit block 71. The proximity sensor 72 can monitor the distance between the rust removal mechanism 4, the pickling mechanism 5 and the titanium infiltration mechanism 6 and the limit block 71 in real time, and timely feed back the monitored distance information to the PCL control system. The PCL control system can make judgments and processes in advance based on this information. When the mechanism approaches the limit block 71 and reaches a preset safety distance, corresponding measures can be taken, such as reducing the movement speed of the mechanism or stopping its movement to avoid collision. In addition, the anti-collision limit mechanism 7 also includes an elastic member 73, which is installed on the side of the limit block 71 close to the inside of the moving track 3. The elastic member 73 is usually made of a material with good elastic properties, such as a spring or an elastic rubber block. Its purpose is to play a buffering role when an accident occurs, that is, when the mechanism collides with the limit block 71, effectively absorb part of the impact force, further reduce the damage caused by the collision to the mechanism and equipment, and ensure the stability and safety of the entire system.

[0048] In the embodiment of the present invention, the structure and connection relationship of the rust removal mechanism 4 are as follows: Figure 3As shown, it includes a first frame 41, and a first driving motor is installed inside the first frame 41. The first driving motor is a power source for driving the rust removal mechanism 4 to move on the moving track 3, and its output shaft is connected to the first running wheel 42 through a first transmission component. The first running wheel 42 is installed at the bottom of the first frame 41, and its size and structure match the moving track 3 to ensure that it can run smoothly on the track during the movement. In addition, a first braking system is also installed on the first running wheel 42, and the braking system can brake the first running wheel 42 to cooperate with the rust removal operation. In addition, a second drive motor 43 and a first gearbox 44 are installed on the upper part of the first frame 41. The second drive motor 43 serves as another power source and is connected to the rust removal grinding wheel 45 through the first gearbox 44. The function of the first gearbox 44 is to adjust the speed and torque output by the second drive motor 43 to adapt to different rust removal work requirements, so that the rust removal grinding wheel 45 can perform rust removal operations on the reactor at a suitable speed and torque. The rust removal grinding wheel 45 is made of high hardness and wear-resistant materials, such as tungsten carbide or diamond, and can effectively remove rust on the surface of reactor A.

[0049] It is worth noting that the first drive motor, the first brake system, the second drive motor 43 and the first gearbox 44 are all connected to the PCL control system. The PCL control system can accurately control the start, stop and speed of the first drive motor, thereby realizing accurate control of the moving speed and position of the rust removal mechanism 4 on the moving track 3; at the same time, the PCL control system can control the braking operation of the first brake system according to actual conditions to ensure the safe operation of the rust removal mechanism 4; for the second drive motor 43 and the first gearbox 44, the PCL control system can adjust the speed and torque output of the second drive motor 43, and control the working state of the rust removal grinding wheel 45 through the speed change function of the first gearbox 44, and realize different degrees of rust removal operations on the reactor A according to different rust removal tasks.

[0050] In the embodiment of the present invention, the structure and connection relationship of the pickling mechanism 5 are as follows: Figure 4 As shown, it includes a second frame 51, a third drive motor is installed inside the second frame 51, and the output shaft of the third drive motor is connected to the second running wheel 52 installed at the bottom of the second frame 51 and matched with the moving track 3 through the second transmission component, and a braking system can also be set on the second running wheel 52 (similar to the rust removal mechanism 4, no longer detailed). And the third drive motor braking system is respectively connected to the PCL control system, and the PCL control system can control the speed and direction of the third drive motor, and then adjust the moving speed and moving direction of the pickling mechanism 5 on the moving track 3 to ensure that it can accurately reach the position where pickling is required.

[0051] Further, the pickling mechanism 5 is fixedly mounted with a first storage tank 53 on the upper part of the second frame 51. The first storage tank 53 is used to contain a rust removal medium, such as an acid solution. The first storage tank 53 is made of acid-resistant materials (such as polytetrafluoroethylene or metal lined with anti-corrosion materials) to ensure that the stored rust removal medium will not cause corrosion to it. The bottom of the first storage tank 53 is connected to the nozzle 55 through the first feed pipeline 54 to form a complete material conveying channel. The first feed pipeline 54 can be made of corrosion-resistant and bendable materials. The nozzle 55 is an atomizing nozzle or a fan-shaped nozzle, which can evenly spray the rust removal medium on the surface of the reactor A to achieve a better pickling effect. Moreover, the nozzle 55 is connected to the PCL control system, which can control the time of its opening and closing, adjust the flow rate and spraying angle of the nozzle 55, and realize accurate control of the pickling process, so that the pickling operation can be completed more accurately and efficiently.

[0052] In the embodiment of the present invention, the structure and connection relationship of the titanium infiltration mechanism 6 are as follows: Figure 5 As shown, it includes a third frame 61, which is the main structure supporting the entire titanium infiltration mechanism. It is similar to the first frame 41 and the second frame 51 in structure, and the materials are all made of high-strength metal, which provides a stable installation and bearing foundation for each internal component. A fourth drive motor is installed inside it, which is used as a power source to drive the titanium infiltration mechanism 6 to move on the moving track 3, and provides power support for the position adjustment during the entire titanium infiltration process. The output shaft of the fourth drive motor is connected to the third walking wheel 62 matching the moving track 3 through the third transmission component. The third walking wheel 62 is installed at the bottom of the third frame 61 and is equipped with a second braking system. The braking system can adopt electromagnetic braking, hydraulic braking or mechanical braking. The fourth drive motor and the second braking system are respectively connected to the PCL control system. The PCL control system is used to control the start, stop, speed and direction of the fourth drive motor, and then control the moving speed and direction of the titanium infiltration mechanism 6 on the moving track 3; for the second braking system, the PCL control system can issue braking instructions in time according to actual conditions to ensure the docking position.

[0053] Further, a fifth drive motor 63 and a second gearbox 64 are installed on the upper part of the third frame 61. The fifth drive motor 63 is used as a power source for driving the titanium powder brush roller 66. It is connected to the titanium powder brush roller 66 through the second gearbox 64 and the second feed pipe 65. The second gearbox 64 plays a role in adjusting the output speed and torque of the fifth drive motor 63. According to different titanium infiltration process requirements, the rotation speed and rotation torque of the titanium powder brush roller 66 are adjusted to achieve the best effect of the titanium infiltration process. The second feed pipe 65 is a key component for transporting the titanium water medium from the second storage tank 67 to the titanium powder brush roller 66. It is connected to the second gearbox 64 by a rotary seal. This sealed connection method ensures that the titanium water medium will not leak while the second gearbox 64 rotates. The end of the second feed pipe 65 away from the titanium powder brush roller 66 is connected to the second storage tank 67 through a connecting pipe. The second storage tank 67 is installed on the second gearbox 64 for accommodating the titanium water medium. A control valve is installed on the connecting pipe. The control valve can control the flow of the titanium water medium and is an important component for realizing material flow control during the titanium infiltration process. In addition, the fifth drive motor 63, the second gearbox 64 and the control valve are all connected to the PCL control system. For the fifth drive motor 63 and the second gearbox 64, the PCL control system can adjust the speed and torque output of the fifth drive motor 63, and accurately control the working state of the titanium powder brush roller 66 through the speed change function of the second gearbox 64. At the same time, the PCL control system can accurately control the flow rate of the titanium water medium through the control valve to ensure that the titanium water medium can be delivered to the titanium powder brush roller 66 in an appropriate amount, so that the titanium infiltration operation is accurately carried out according to the predetermined process requirements.

[0054] Preferably, the present invention is provided with a first liquid level sensor for monitoring the remaining amount of rust removal medium in the first storage tank 43, and a second liquid level sensor for monitoring the remaining amount of titanium water medium in the second storage tank 67, and both the first liquid level sensor and the second liquid level sensor are connected to the PCL control system, so that the first liquid level sensor and the second liquid level sensor can transmit the real-time monitored liquid level information to the PCL control system in the form of electrical signals. Based on the received information, the PCL control system, on the one hand, issues corresponding warning information when the liquid level is too low, prompting the operator to add the corresponding medium; on the other hand, it adjusts the working parameters of the rust removal mechanism 4 and / or the titanium infiltration mechanism 6 according to the change of the liquid level, so as to ensure the best treatment effect under the existing medium.

[0055] Based on the above automatic rust removal, pickling and titanium infiltration device, the rust removal, pickling and titanium infiltration operation of the reactor A (with a large amount of rust and foreign matter on the outer surface) which is used for the first time to produce titanium sponge after just being manufactured is taken as an example, and the operation process is as follows:

[0056] First, the reactor A is placed horizontally on the support frame 1 by means of a lifting device; then the height of the lifting mechanism 2 is adjusted and its position is moved so that the movable track 3 and the rust removal mechanism 4 and the pickling mechanism 5 installed thereon are located outside the reactor A; the support frame 1, the rust removal mechanism 4 and the pickling mechanism 5 are coordinated and controlled by the PCL control system to perform rust removal and pickling operations on the outside of the reactor A; finally, the lifting mechanism 2 is adjusted so that the movable track 3 and the rust removal mechanism 4 and the titanium infiltration mechanism 6 installed thereon are located inside the reactor A, and the support frame 1, the rust removal mechanism 4 and the titanium infiltration mechanism 6 are coordinated and controlled by the PCL control system to perform rust removal and titanium infiltration operations on the inside of the reactor A.

[0057] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
