Description

Technical Field

[0001] The present invention belongs to the technical field of mixing devices, and more specifically, relates to a raw material mixing device for the production and preparation of TC4 titanium alloy. Background Art

[0002] In the production process of TC4 titanium alloy products, the raw materials made by mixing various metal powders in a specific proportion are the basis for producing high-quality TC4 titanium alloy products. To ensure the uniform texture of the final product, it is a crucial production link to fully mix various metal powders to a uniform state.

[0003] During the mixing process of TC4 titanium alloy raw materials, common mixing devices are generally equipped with stirring blades to achieve the mixing operation; however, most existing mixing equipment aims to solve the problem of whether the mixing is uniform, and the uniformity of mixing is mainly restricted by the shape and size of the stirring blades. Therefore, many mixing equipment also aims to improve the mixing uniformity, usually by re-setting the shape and size of the stirring blades, or making the mixing barrel capable of rotating, tumbling, flipping and other actions. But when the mixing barrel is fixedly arranged, how to further improve the mixing uniformity of TC4 titanium alloy raw material powder by re-designing the stirring blades is a technical problem that needs to be solved urgently. For this reason, a raw material mixing device for the production and preparation of TC4 titanium alloy is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a raw material mixing device for the production and preparation of TC4 titanium alloy that can overcome or at least partially solve the above problems.

[0005] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a raw material mixing device for the production and preparation of TC4 titanium alloy, including a mixing barrel, and further including: a connecting shaft rotatably arranged in the mixing barrel, and a stirring assembly is installed on the connecting shaft; while the stirring assembly rotates following the connecting shaft, it performs irregular or regular up-and-down displacement, and when the stirring assembly moves up and down in the mixing barrel, it uses the disturbance area formed by itself to stir the inside of the mixing barrel, so that the materials in the mixing barrel are tumbled up and down disorderly.

[0006] Preferably, the stirring assembly includes a first connecting rod connected to the connecting shaft, a sleeve is slidably connected to the first connecting rod, a spiral blade is fixedly connected to the outer diameter of the sleeve, a spiral disturbance area is formed between adjacent spiral blades, a first fixing block is fixedly connected to the first connecting rod, and a first spring is sleeved on the first connecting rod between the first fixing block and the sleeve.

[0007] Preferably, the stirring assembly includes a second connecting rod connected to the connecting shaft. Mounting blocks are fixedly connected to both ends of the second connecting rod, and second sliders are slidably connected thereto. Multiple groups of first arm rods and second arm rods are rotatably connected to the mounting blocks and the second sliders respectively. One ends of the first arm rods and the second arm rods are rotatably connected to each other, so that a triangular outspread wing is formed between the first arm rods, the second arm rods and the second connecting rod, and a triangular disturbance area is formed. A second fixing block is fixedly connected to the second connecting rod. A second spring is sleeved on the second connecting rod between the second fixing block and the second slider. When the second slider moves upward, the triangular outspread wing extends towards the inner wall of the mixing barrel; when the second slider moves downward and resets, the second spring drives the triangular outspread wing to reset.

[0008] Further, wing plates are fixedly connected to the outer sides of the first arm rods and the second arm rods. Openings that can be opened when the triangular outspread wing extends and openings that can be closed when the triangular outspread wing resets are provided on the wing plates.

[0009] Further, a switching plate is slidably connected in the sandwich layer of the wing plate. The openings are respectively formed in the switching plate and the wing plate. A chute is formed in the wing plate, and hinge arm rods are connected between adjacent wing plates through the chute.

[0010] Further, a first slider is slidably connected to the second connecting rod. A plurality of telescopic rods are fixedly connected to the circumference of the first slider. One ends of the telescopic rods are rotatably connected to the connection points of the first arm rods and the second arm rods.

[0011] Further, third sliders are slidably connected to both sides of the first slider on the second connecting rod. A deflector is rotatably connected to the third slider. The deflector is rotatably connected to the adjacent first arm rod and second arm rod; when the second slider moves upward, a zigzag disturbance area is formed between the deflector and the telescopic rod; when the second slider moves downward and resets, a cross-shaped disturbance area is formed between the deflector and the telescopic rod.

[0012] Further, a second magnet is slidably connected to the end of the first connecting rod. The second magnet is in contact with one end of the sleeve. A telescopic cylinder is installed at the bottom of the mixing barrel. The telescopic end of the telescopic cylinder extends into the mixing barrel. A fourth magnet is installed on the telescopic end of the telescopic cylinder. The fourth magnet repels the second magnet.

[0013] Preferably, a third magnet is slidably connected to the end of the second connecting rod. The third magnet is in contact with the second slider. A telescopic cylinder is installed at the bottom of the mixing barrel. The telescopic end of the telescopic cylinder extends into the mixing barrel. A fourth magnet is installed on the telescopic end of the telescopic cylinder. The fourth magnet repels the third magnet.

[0014] Preferably, an upper mounting plate is fixedly connected to the upper opening of the mixing barrel. Flip covers are rotatably connected to both sides of the upper mounting plate. A first motor is mounted on the upper mounting plate, and the output end of the first motor is connected to a connecting shaft to drive the connecting shaft to rotate.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: during the up-and-down movement of the spiral blade, the present invention can improve the stirring effect on the material, making the material tumble up and down. Therefore, compared with the fixed stirring blades in the prior art, the material can be stirred better and faster, and the spiral blade moves up and down regularly or irregularly, thereby increasing the diversity of material flow, reducing dead zones, and making the material mixing more uniform.

[0016] When the third magnet slides upward, it pushes the second slider upward, which reduces the angle between the first arm and the second arm, thereby expanding the stirring range. The connection between the first arm and the second arm extends away from the second connecting rod, and thus the triangular outrigger extends outward. During the extension process, the randomness of stirring the material in the mixing barrel is increased, making the mixing effect faster and more uniform. At the same time, when the triangular outrigger extends and resets, it can make the material tumble up and down, improving the material mixing effect.

[0017] The movement of the first arm and the second arm will also cause the triangular disturbance area formed by the first arm, the second arm, and the second connecting rod to change continuously, increasing the diversity of material flow, reducing dead zones, and making the material mixing more uniform. Compared with the fixed stirring blades in the prior art, this device can arbitrarily change the size of the triangular outrigger and the size of the triangular disturbance area during the stirring process of the material.

[0018] The setting of the wing plate can increase the contact area between the first arm, the second arm and the material. The provided openable holes can adaptively change according to the change in the size of the triangular outrigger. Therefore, when the triangular outrigger is not extended, the holes are in a closed state, thereby enhancing the stirring effect on the material around the connecting shaft, enabling the material around the connecting shaft to be pushed outward by the wing plate, and thus improving the mixing uniformity. When the triangular outrigger extends, the holes open, thereby reducing the impact of the material on the wing plate, reducing the resistance on the wing plate, and avoiding factors such as structural deformation from affecting normal use.

[0019] When the second slider does not slide, a cross-shaped disturbance area is formed between the guide plates on both sides of the telescopic rod and the telescopic rod. The cross-shaped disturbance area can form intricate obstacles in space, and thus when rotating, it can have a better mixing effect on the material.

[0020] When the second slider moves upward, that is, the first arm rod and the second arm rod extend, the cross-shaped disturbance area changes into a zigzag disturbance area, forming multiple horizontally inclined barriers in space. On the one hand, it can improve the mixing effect of the materials, and on the other hand, it can also weaken the impact on the first arm rod and the second arm rod. More importantly, the cross-shaped disturbance area and the zigzag disturbance area change continuously. Therefore, compared with the fixed stirring blades in the prior art, this device can better achieve uniform mixing of the materials.

Detailed implementation manners

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0043] The following combines the attached Figure 1 - attached Figure 18 , and will detail the technical solutions provided by each embodiment of the present invention.

[0044] Embodiment 1: Refer to Figures 1 - 9 , a raw material mixing device for the production and preparation of TC4 titanium alloy, including a mixing barrel 1 equipped with legs 11. At the upper opening of the mixing barrel 1, an upper mounting plate 12 is fixedly connected. On both sides of the upper mounting plate 12, flaps 13 are rotatably connected. A first motor 14 is installed on the upper mounting plate 12, and a control box 141 for controlling the first motor 14 is also installed. The output end of the first motor 14 is connected to a connecting shaft 16 to drive the rotation of the connecting shaft 16. A feed valve 15 is installed on the mixing barrel 1, which can be used to discharge materials into the mixing barrel 1 through the feed valve 15. A discharge valve is provided at the bottom, which can be used to discharge the mixed materials. It also includes: a connecting shaft 16 rotatably arranged in the mixing barrel 1, and a stirring assembly is installed on the connecting shaft 16; while the stirring assembly rotates following the connecting shaft 16, it performs irregular or regular up and down displacements. When the stirring assembly moves up and down in the mixing barrel 1, it stirs the inside of the mixing barrel 1 by using the disturbance area formed by itself, so that the materials in the mixing barrel 1 are disorderly tumbled up and down;

[0045] The stirring assembly includes a first connecting rod 21 connected to the connecting shaft 16. A sleeve 26 is slidably connected to the first connecting rod 21. A spiral blade 27 is fixedly connected to the outer diameter of the sleeve 26. A spiral disturbance area is formed between adjacent spiral blades 27. A first fixing block 23 is fixedly connected to the first connecting rod 21. A first spring 24 is sleeved on the first connecting rod 21 between the first fixing block 23 and the sleeve 26. A first protective sleeve 25 is arranged between the first fixing block 23 and the sleeve 26. A second magnet 28 is slidably connected to the end of the first connecting rod 21. The second magnet 28 is in contact with one end of the sleeve 26. A telescopic cylinder 167 (the telescopic cylinder 167 uses a hydraulic cylinder or a pneumatic cylinder) is installed at the bottom of the mixing barrel 1. The telescopic end of the telescopic cylinder 167 extends into the mixing barrel 1. A fourth magnet 166 is installed on the telescopic end of the telescopic cylinder 167. The fourth magnet 166 repels the second magnet 28.

[0046] During the use of the device, the first motor 14 drives the connecting shaft 16 to rotate, thereby causing the first connecting rod 21 to rotate. During the rotation of the connecting shaft 16, the telescopic end of the telescopic cylinder 167 moves up and down reciprocally in an irregular or regular manner. When the telescopic end moves upward, it will cause the fourth magnet 166 to approach the second magnet 28, causing the fourth magnet 166 to generate a repulsion on the second magnet 28, causing the second magnet 28 to move upward on the first connecting rod 21. During the upward movement, it will push the sleeve 26 upward, causing the spiral blade 27 to move upward (it should be noted that not too much material will be added to the mixing barrel 1, so when the spiral blade 27 moves upward, the resistance of the material to the spiral blade 27 will not be very large and will not affect the upward movement of the spiral blade 27). The sleeve 26 is slidably connected to the first connecting rod 21 in a limited manner, so the sleeve 26 can rotate with the first connecting rod 21 to stir and mix the material in the mixing barrel 1;

[0047] During the up and down movement of the spiral blade 27, the stirring effect on the material can be improved, enabling the material to roll up and down. Therefore, compared with the fixed stirring blades in the prior art, the material can be stirred better and faster, and the irregular or regular up and down movement of the spiral blade 27 further increases the diversity of material flow, reduces dead zones, and makes the material mixing more uniform.

[0048] Example 2: Refer to Figures 1 - 9, a raw material mixing device for the production of TC4 titanium alloy, comprising a mixing barrel 1. At the upper opening of the mixing barrel 1, there is a fixedly connected upper mounting plate 12. On both sides of the upper mounting plate 12, there are rotatably connected flip covers 13. On the upper mounting plate 12, there is a first motor 14. The output end of the first motor 14 is connected to a connecting shaft 16 to drive the connecting shaft 16 to rotate. On the mixing barrel 1, there is a feed valve 15 through which materials can be discharged into the mixing barrel 1. At the bottom, there is a discharge valve for discharging the mixed materials. It further includes: a connecting shaft 16 rotatably arranged in the mixing barrel 1, and a stirring assembly is installed on the connecting shaft 16; while the stirring assembly rotates with the connecting shaft 16, it makes irregular or regular up and down displacements. When the stirring assembly makes up and down displacements in the mixing barrel 1, it stirs the inside of the mixing barrel 1 by using the disturbance area formed by itself, causing the materials in the mixing barrel 1 to tumble disorderly up and down;

[0049] The stirring assembly includes a second connecting rod 3 connected to the connecting shaft 16. At both ends of the second connecting rod 3, there are respectively fixedly connected mounting blocks 32 and slidably connected second sliders 34. On the mounting blocks 32 and the second sliders 34, there are respectively rotatably connected multiple groups of first arm rods 321 and second arm rods 322. The number of each group of the first arm rods 321 and the second arm rods 322 is 2, 3, 4, or 6, and the specific number can be set according to the actual production situation. One end of the first arm rod 321 and the second arm rod 322 is rotatably connected, so that a triangular outrigger wing is formed between the first arm rod 321, the second arm rod 322 and the second connecting rod 3, and a triangular disturbance area is formed. A second fixing block 341 is fixedly connected to the second connecting rod 3. A second spring 342 is sleeved on the second connecting rod 3 between the second fixing block 341 and the second slider 34. When the second slider 34 moves upward, the triangular outrigger wing extends towards the inner wall of the mixing barrel 1; when the second slider 34 moves downward and resets, the second spring 342 drives the triangular outrigger wing to reset; a third magnet 35 is slidably connected to the end of the second connecting rod 3, and the third magnet 35 is in contact with the second slider 34. A telescopic cylinder 167 is installed at the bottom of the mixing barrel 1, and the telescopic end of the telescopic cylinder 167 extends into the mixing barrel 1. A fourth magnet 166 is installed on the telescopic end of the telescopic cylinder 167, and the fourth magnet 166 repels the third magnet 35;

[0050] When the telescopic end of the telescopic cylinder 167 moves up and down reciprocally in a regular or irregular manner, the fourth magnet 166 repels the third magnet 35. When the third magnet 35 slides upward, it pushes the second slider 34 upward, which reduces the angle between the first arm rod 321 and the second arm rod 322, thereby expanding the stirring range. The connection between the first arm rod 321 and the second arm rod 322 extends away from the second connecting rod 3, thereby causing the triangular outrigger to extend outward. During the extension process, the randomness of the stirring of the materials in the mixing barrel 1 is increased, making the mixing effect faster and more uniform. At the same time, when the triangular outrigger extends and resets, it can cause the materials to roll up and down, improving the mixing effect of the materials;

[0051] The movement of the first arm rod 321 and the second arm rod 322 will also cause the triangular disturbance area formed by the first arm rod 321, the second arm rod 322, and the second connecting rod 3 to change continuously, increasing the diversity of material flow, reducing dead zones, and making the material mixing more uniform. Compared with the fixed stirring blades in the prior art, this device can arbitrarily change the size of the triangular outrigger and the size of the triangular disturbance area during the stirring process of the materials.

[0052] Wing plates 33 are fixedly connected to the outer sides of the first arm rod 321 and the second arm rod 322. The wing plates 33 are provided with openings 331 that can be opened when the triangular outrigger extends, and the openings 331 that can be closed when the triangular outrigger resets;

[0053] The setting of the wing plates 33 can increase the contact area between the first arm rod 321, the second arm rod 322 and the materials. The provided openings 331 that can open and close can change adaptively according to the change in the size of the triangular outrigger. Therefore, when the triangular outrigger is not extended, the openings 331 are in a closed state, thereby enhancing the stirring effect on the materials around the connecting shaft 16, enabling the materials located around the connecting shaft 16 to be pushed outward by the wing plates 33, thereby improving the mixing uniformity;

[0054] When the triangular outrigger extends, the openings 331 open, thereby reducing the impact of the materials on the wing plates 33, reducing the resistance received by the wing plates 33, and avoiding factors such as structural deformation from affecting normal use.

[0055] A switching plate 332 is slidably connected in the sandwich layer of the wing plate 33. The openings 331 are respectively opened on the switching plate 332 and the wing plate 33. A sliding groove 333 is opened on the wing plate 33. Adjacent wing plates 33 are connected by a hinge arm rod 334 through the sliding groove 333. One end of the switching plate 332 is rotatably connected to one end of the hinge arm rod 334 located in the sliding groove 333;

[0056] The opening and closing control of the opening 331 is that when the second slider 34 moves upward, the angle between the first arm 321 and the second arm 322 decreases, and the connection between the first arm 321 and the second arm 322 abuts against the middle part of the hinge arm 334, pushing the hinge arm 334 to slide in the slide slot 333 toward the connection between the first arm 321 and the second arm 322, thereby pulling the switching plate 332 to slide in the interlayer, so that the opening 331 on the switching plate 332 coincides with the opening 331 on the wing plate 33, thereby opening the opening 331;

[0057] When the first arm 321 and the second arm 322 are reset, the hinge arm 334 is also reset accordingly, so that the opening 331 on the switching plate 332 is offset from the opening 331 on the wing plate 33, so that the opening 331 is closed.

[0058] The second connecting rod 3 is slidably connected to a first slider 320, and a plurality of telescopic rods 323 are fixedly connected to the circumference of the first slider 320. One end of the telescopic rod 323 is rotatably connected to the connection between the first arm 321 and the second arm 322. The telescopic rod 323 can be used to enhance the stability between the first arm 321 and the second arm 322. At the same time, during the material mixing process, the telescopic rod 323 can also play an effect of stirring the material;

[0059] It should be supplemented that a corrugated protective sleeve is provided between the telescopic rod 323 and the telescopic end to prevent the material from getting stuck in the telescopic rod 323 .

[0060] The second connecting rod 3 is located on both sides of the first slider 320 and is slidably connected to the third slider 361. The third slider 361 is rotatably connected to the guide plate 36. The guide plate 36 is rotatably connected to the adjacent first arm 321 and the second arm 322. When the second slider 34 moves upward, a "川"-shaped disturbance zone is formed between the guide plate 36 and the telescopic rod 323.

[0061] When the second slider 34 moves downward to reset, a cross-shaped disturbance zone is formed between the guide plate 36 and the telescopic rod 323;

[0062] When the second slider 34 does not slide, a cross-shaped disturbance zone is formed between the guide plates 36 on both sides of the telescopic rod 323 and the telescopic rod 323. The cross-shaped disturbance zone can form an intricate barrier in space, thereby achieving a better mixing effect on the material when rotating.

[0063] When the second slider 34 moves upward, that is, the first arm 321 and the second arm 322 are extended, the M-shaped disturbance zone changes to a C-shaped disturbance zone, so that multiple horizontal barriers are formed in space, which can improve the mixing effect of the materials on the one hand, and reduce the impact on the first arm 321 and the second arm 322 on the other hand;

[0064] More importantly, the cross-shaped disturbance area and the grid-shaped disturbance area are continuously changing. Therefore, compared with the stirring blades fixedly arranged in the prior art, the device can better achieve uniform mixing of materials.

[0065] It should be added that dust-proof corrugated sleeves are provided between the mounting block 32 and the adjacent third slider 361, between the first slider 320 and the third sliders 361 on both sides, and between the second fixing block 341 and the adjacent third slider 361 to prevent dust from getting stuck. A second protective sleeve 343 is provided between the second fixing block 341 and the second slider 34. For the rotation or sliding parts of other structures, whether to set dust-proof sleeves can be selected according to actual situations.

[0066] In one embodiment, the driving spiral blade 27, the first arm 321, and the second arm 322 can be driven by the telescopic end of the telescopic cylinder 167 directly abutting against the sleeve 26 or the second slider 34.

[0067] Example 3: Refer to Figures 9 - 18 , a raw material mixing device for the production and preparation of TC4 titanium alloy, including a mixing barrel 1, and further including: a connecting shaft 16 rotatably arranged in the mixing barrel 1, a stirring blade assembly is installed on the connecting shaft 16, the stirring blade assembly includes a sleeve block 161 installed on the connecting shaft 16, an inclined plate 162 is installed on the sleeve block 161, and a stirring plate 163 is installed on the inclined plate 162; a disturbance assembly circumferentially arranged on the inner wall of the mixing barrel 1, which cooperates with the stirring blade assembly to stir the lower part of the mixing barrel 1; the disturbance assembly rotates around the mixing barrel 1 while revolving, and when the disturbance assembly is opposite to the driving assembly installed on the connecting shaft 16, the disturbance assembly makes a reciprocating radial movement in the vertical direction of the connecting shaft 16, causing radial disturbance of the raw material powder in the mixing barrel 1;

[0068] On the inner wall of the mixing barrel 1, there are symmetrically and fixedly connected limit rings 171. Between the two limit rings 171, there is an externally toothed ring 17 connected in a rotationally embedded manner. An opening groove is provided on the mixing barrel 1. A second motor is installed on the outer wall of the mixing barrel 1 at the opening groove. The control box 141 is also used to control the second motor. A gear 175 is installed on the output end of the second motor. The gear 175 meshes with the externally toothed ring 17. The disturbing component is installed on the inner diameter of the externally toothed ring 17. A planar toothed ring 172 is fixedly connected to the inner wall of the mixing barrel 1. The first connecting rod 21 is rotationally connected to the inner diameter of the externally toothed ring 17 through the support frame 2. The support frame 2 is fixedly connected to the inner diameter of the externally toothed ring 17. One end of the first connecting rod 21 is fixedly connected with a first bevel gear 22. There is a collision area 10 formed between the spiral blade 27 and the connecting shaft 16. The driving component includes three connecting columns 164 fixedly connected to the circumference of the connecting shaft 16. A first magnet 165 is installed at one end of the connecting column 164. The first magnet 165 repels the second magnet 28 on the first connecting rod 21. The rotation direction of the connecting shaft 16 is opposite to that of the externally toothed ring 17.

[0069] The second motor drives the gear 175 to rotate. The gear 175 meshes and drives the externally toothed ring 17 to rotate in the mixing barrel 1, so that while the first connecting rod 21 revolves around the mixing barrel 1, it meshes with the teeth on the upper surface of the planar toothed ring 172 through the first bevel gear 22, causing the first connecting rod 21 to rotate on its own axis, thereby realizing rotation on its own axis while revolving.

[0070] The spiral blade 27 rotates on its own axis in the mixing barrel 1, pushing the material towards the stirring blade assembly on the connecting shaft 16, thereby generating a collision area 10 in the mixing barrel 1, making the material mixing more uniform.

[0071] At the same time, when the first magnet 165 and the second magnet 28 are opposite to each other, the spiral blade 27 slides on the first connecting rod 21, and together with the rotating spiral blade 27, it causes the raw material powder in the mixing barrel 1 to generate a radial displacement, thereby improving the mixing effect.

[0072] In another embodiment, the second connecting rod 3 is rotationally connected to the support frame 2. At the same time, a second bevel gear 31 is installed at one end of the second connecting rod 3. The second bevel gear 31 meshes with the planar toothed ring 172, thereby realizing the expansion of the triangular outer wing in the direction perpendicular to the connecting shaft 16 and rotating on its own axis while revolving, so as to provide a mixing effect.

[0073] In another embodiment, referring to Figure 15 , the first connecting rod 21 and the second connecting rod 3 can be combined and arranged in the mixing barrel 1 to improve the randomness during the stirring of the material, thereby enhancing the mixing effect.
