Description

Technical Field

[0001] The present invention relates to the technical field of nickel-based welding material granulation, and specifically, it is an efficient granulation device for nickel-based welding material processing. Background Art

[0002] Nickel-based welding materials are welding materials with nickel or nickel alloy as the matrix, having excellent high-temperature resistance and corrosion resistance. During the processing, granulation is a key step in making the mixed raw materials into particles, aiming to improve the fluidity, wire feeding stability and melting uniformity of the welding materials. The evenness of the raw material mixture before granulation directly affects the consistency of the particle composition. If the nickel-based metal powder, additives and binders are unevenly distributed, it will lead to internal structural defects and composition segregation in the particles, thereby reducing the mechanical properties and welding quality of the welding materials. Therefore, ensuring the full and even dispersion of the raw materials through an efficient mixing device is the core prerequisite for ensuring the performance stability and processing efficiency of nickel-based welding materials.

[0003] The existing equipment for mixing raw materials during the granulation of nickel-based welding materials usually adopts a powerful mixer. This equipment drives a plurality of stirring rollers through two independently rotating rotating shafts to continuously and rapidly mix the nickel-based metal powder, additives and binders added into the mixing cylinder body. And the mixing cylinder body is also driven by a separate power device and continuously rotates. At the same time, the mixing cylinder body itself is in an inclined state. Through the cooperation of the above actions, the nickel-based metal powder, additives and binders can be quickly mixed.

[0004] Although the above equipment can effectively mix the nickel-based metal powder, additives and binders, there are still the following problems: First, although the above equipment simultaneously and rapidly mixes the nickel-based metal powder, additives and binders through the mixing cylinder body, two rotating shafts and a plurality of stirring rollers, since the two rotating shafts are in an eccentric position in the mixing cylinder body, the two rotating shafts and a plurality of stirring rollers cannot cover the internal area of the mixing cylinder body for comprehensive mixing, thus affecting the mixing evenness and mixing efficiency of the nickel-based metal powder, additives and binders; In addition, the above equipment usually adopts the method of directly feeding materials through an input pipe to add the nickel-based metal powder or additives and binders. When a large amount of additives and binders are input into the mixing cylinder body, agglomeration and adhesion phenomena will occur in this part, resulting in an increase in the mixing workload, and in severe cases, the additives and binders will not be separated and evenly mixed. Summary of the Invention

Detailed implementation mode

[0029] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments in terms of specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0030] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 , a high-efficiency granulating device for nickel-based welding materials processing, including an inclined base 1. Support blocks 11 are symmetrically installed on the left and right of the inclined surface of the inclined base 1. A mixing cylinder 2 is rotatably installed between the two support blocks 11 through a limiting sleeve 111. A rotary power assembly 21 is jointly arranged between the right support block 11 and the mixing cylinder 2. A mixing and stirring mechanism 3 is jointly arranged between the tops of the two support blocks 11 and the mixing cylinder 2. A discharge assembly 22 is arranged between the bottom of the mixing cylinder 2 and the inclined base 1.

[0031] An annular receiving box 23 is arranged on the mixing cylinder 2. A plurality of through holes are uniformly opened at the bottom of the receiving box 23. An annular opening 231 is opened at the top of the receiving box 23. A feeding port 24 and a powder inlet 25 are sequentially arranged on the front and back of the sealing cover 31.

[0032] The present invention ensures that the nickel-based metal powder, additives and adhesives are fully and evenly mixed by the synchronous rotation of the mixing drum 2 and the mixing and stirring mechanism 3, thereby ensuring the quality of the nickel-based welding material raw materials after mixing. At the same time, the discharging component 22 can facilitate the discharging of the mixed nickel-based welding material raw materials, and the continuous rotation of the mixing drum 2 drives the containing box 23 to add additives and adhesives, which can further improve the uniformity of the mixing of the additives and adhesives with the nickel-based metal powder during the mixing process.

[0033] Specifically, first, the nickel-based metal powder is introduced through the powder inlet 25, and then the rotating power component 21 is controlled to drive the mixing drum 2 to rotate. During the rotation of the mixing drum 2, the mixing and stirring mechanism 3 is controlled to first stir the added nickel-based metal powder, and then additives and adhesives are continuously added through the feeding port 24. As the additives and adhesives are added, some additives and adhesives will accumulate in the containing box 23. During the rotation of the containing box 23 with the mixing drum 2, the additives and adhesives in the containing box 23 will be evenly sprinkled on the stirred nickel-based metal powder, thereby ensuring that the nickel-based metal powder and the additives and adhesives are more quickly and evenly mixed. After the addition of the additives and adhesives is completed, the additives and adhesives are further mixed with the nickel-based metal powder through the mixing and stirring mechanism 3. After the mixing is completed, the mixed nickel-based welding material raw material is discharged through the discharging component 22.

[0034] It should be noted that during the process of mixing additives and adhesives with nickel-based metal powder, the inside of the mixing barrel 2 needs to be heated. Therefore, a heating element for heating the inside of the mixing barrel 2 is provided in the support block 11. This heating element and heating method are relatively common and widely used in existing equipment, so they will not be elaborated on.

[0035] See also Figure 1 , Figure 2 , Figure 5 and Figure 8 The rotating power assembly 21 includes an avoidance groove opened in the right support block 11, and a motor 211 is installed on the right side of the right support block 11 through a motor box. A horizontal shaft 212 that penetrates the support block 11 is installed at the output end of the motor 211, and a driving bevel gear 213 is fixed at one end of the horizontal shaft 212 close to the mixing barrel 2, and a driven bevel gear 214 that meshes with the driving bevel gear 213 is fixed at the bottom of the mixing barrel 2.

[0036] The rotary power assembly 21 is used to drive the mixing cylinder 2 to rotate continuously. By the continuous rotation of the mixing cylinder 2, it can prevent the nickel-based metal powder, additives and binder from adhering to the side wall of the mixing cylinder 2, and can improve the mixing effect of the nickel-based metal powder, additives and binder. Specifically, after the nickel-based metal powder is introduced through the powder inlet 25, the first motor 211 is controlled to drive the horizontal shaft 212 to rotate. As the horizontal shaft 212 rotates, the horizontal shaft 212 will continuously drive the driving bevel gear 213 to rotate, so that the driving bevel gear 213 cooperates with the driven bevel gear 214 to drive the mixing cylinder 2 to rotate continuously. As the mixing cylinder 2 rotates continuously, the nickel-based metal powder in the mixing cylinder 2 will rotate accordingly. When the nickel-based metal powder rotates to a certain extent, the nickel-based metal powder will fall due to the inclined state of the mixing cylinder 2, thereby improving the evenness of the dispersion of the nickel-based metal powder.

[0037] Refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 8 The mixing and stirring mechanism 3 includes a closed cover 31 fixed between two support blocks 11. The connecting shafts 311 are symmetrically and rotatably installed on the left and right sides of the closed cover 31. The stirring rollers 312 are staggeredly arranged at the lower ends of the connecting shafts 311. An automatically adjustable plowing component 32 is arranged between the lower side of the stirring roller 312 on the connecting shaft 311 and the mixing cylinder 2. A turning component 33 capable of vertically reciprocating is installed at the top of the closed cover 31 and behind the connecting shaft 311. The pushing components 34 for pushing the additives and binder accumulated in the accommodating box 23 and passing through the through holes are evenly arranged circumferentially at the bottom of the closed cover 31.

[0038] A power structure for driving the connecting shaft 311 is arranged between the two support blocks 11 and the closed cover 31; the power structure includes a mounting plate 313 fixed on the side of the support block 11 away from the limit sleeve 111. The second motor 314 is installed on the top of the mounting plate 313 through a motor base. The output end of the second motor 314 is provided with a transmission shaft 315. The output end of the transmission shaft 315 is fixed with a driving pulley. The top of the connecting shaft 311 penetrates through the closed cover 31 and is installed with a driven pulley. A transmission belt is connected between the driving pulley and the corresponding driven pulley.

[0039] Through the mutual cooperation of the plowing component 32 and the turning component 33, the nickel-based metal powder, additives and binder in the mixing cylinder 2 are fully and evenly mixed, so that the additives can cooperate with the binder to complete the coating of the nickel-based metal powder under heating conditions. And by the way of adding the additives and binder through the cooperation of the accommodating box 23 and the pushing component 34, it can further ensure the evenness of the addition of the additives and binder, and enable the additives and binder to be mixed with the nickel-based metal powder more quickly after feeding.

[0040] Specifically, during the process of the mixing cylinder 2 rotating and mixing the nickel-based metal powder, additives and adhesives are continuously added to the feeding port 24. During the addition of additives and adhesives, the additives and adhesives will first fall into the accommodating box 23. At this time, the accommodating box 23 rotates together with the mixing cylinder 2. During the rotation of the accommodating box 23, part of the additives and adhesives will fall into the nickel-based metal powder in the lower mixing process through the through holes. As the accommodating box 23 rotates, the pushing member 34 will continuously push the additives and adhesives, which can not only prevent the additives and adhesives from agglomerating and being unable to pass through the through holes, but also ensure more uniform mixing of the nickel-based metal powder, additives and adhesives by simultaneously feeding the additives and adhesives at multiple locations.

[0041] During the mixing process of the nickel-based metal powder, additives and adhesives, the control motor two 314 drives the transmission shaft 315 to rotate. As the transmission shaft 315 rotates, the transmission shaft 315 will synchronously drive the driving pulley and the driven pulley to rotate through the transmission belt. As the driven pulley rotates, the connecting shaft 311 will continuously drive the stirring roller 312 to mix the nickel-based metal powder, additives and adhesives in the mixing cylinder 2. And during the mixing of the three, the turning member 33 and the plowing member 32 can improve the mixing effect and efficiency of the nickel-based metal powder, additives and adhesives.

[0042] Refer to Figure 3 、 Figure 7 and Figure 8 As shown in FIGS. and, the pushing member 34 includes a connecting block 341 fixed to the bottom of the closing cover 31 and having an overall arc shape. The bottom of the connecting block 341 is fixed with an arc-shaped mounting sleeve 342. An arc-shaped plate 343 is slidably connected to the arc-shaped mounting sleeve 342 along the circumferential direction of the closing cover 31. A compression spring is connected between the arc-shaped plate 343 and the arc-shaped mounting sleeve 342. A plurality of moving and pushing structures are uniformly arranged on the arc-shaped plate 343 and the arc-shaped mounting sleeve 342 along the circumferential direction of the closing cover 31. A transmission member 344 is rotatably mounted on the arc-shaped mounting sleeve 342. A plurality of trigger push rods 345 for pushing the transmission member 344 are uniformly arranged on the inner circumference of the accommodating box 23.

[0043] The moving and pushing structure includes a receiving push rod 346 slidably penetrating the arc-shaped plate 343. A wedge-shaped guiding block 347 is fixed in the arc-shaped mounting sleeve 342. A guiding inclined surface is provided on the wedge-shaped guiding block 347. A wedge-shaped pushing plate 348 is fixed to the bottom of the receiving push rod 346. A tension spring is connected between the wedge-shaped pushing plate 348 and the arc-shaped plate 343.

[0044] The transmission member 344 is composed of a rotating shaft, a connecting rod and a receiving push plate. A receiving pull rod is installed at the position of the rotating shaft corresponding to the arc-shaped plate 343. A through groove is formed in the connecting rod. The receiving pull rod slides in the through groove, and the size of the through groove is larger than the size of the receiving pull rod.

[0045] The pushing component 34 is used to push the additive and the binder accumulated in the containing box 23, so as to prevent the additive and the binder from accumulating and agglomerating in the containing box 23. At the same time, through the pushing mode of the additive and the binder in the containing box 23 by multiple wedge-shaped pushing plates 348 set at fixed points, the additive and the binder can fall centrally at multiple positions, so as to cooperate with the continuous feeding mode of the additive and the binder during the rotation of the containing box 23, and improve the uniformity of the feeding of the additive and the binder.

[0046] Specifically, during the rotation of the containing box 23, the trigger push rod 345 will rotate together with the containing box 23. When the trigger push rod 345 rotates to the position of the transmission part 344, the transmission part 344 will push the pushed plate, so as to drive the overall rotation of the transmission part 344 through the rotation of the pushed plate, so that the transmission part 344 drives the pulled rod to move through the connecting rod, and further makes the arc-shaped plate 343 move against the rotation direction of the containing box 23. During the movement of the arc-shaped plate 343, the receiving push rod 346 will be pushed downward by the guiding inclined surface of the wedge-shaped guiding block 347, so as to drive the wedge-shaped pushing plate 348 to move downward through the receiving push rod 346. The wedge-shaped pushing plate 348 will push and press downward the additive and the binder accumulated in the containing box 23, so as to prevent the additive and the binder from accumulating and agglomerating, and ensure that the additive and the binder pass through the through hole. At the same time, through the wedge-shaped design of the wedge-shaped pushing plate 348, the situation that the additive and the binder remain on the wedge-shaped pushing plate 348 can be avoided.

[0047] Refer to Figure 6 、 Figure 8 and Figure 9 As shown in FIGS.

[0048] The plowing component 32 includes a limiting groove 321 opened at the lower end of the connecting shaft 311. A pressure-receiving rod 322 is slidably connected in the limiting groove 321 along the axial direction of the connecting shaft 311. A return spring is connected between the pressure-receiving rod 322 and the limiting groove 321. A ball is arranged at the bottom of the pressure-receiving rod 322. An arc-shaped coordination groove 323 is opened at the bottom of the mixing cylinder 2. A plow blade 324 is hinged to the side surface of the connecting shaft 311. A transmission structure is connected between the plow blade 324 and the pressure-receiving rod 322.

[0049] The plowing component 32 can automatically adjust the angle of the plow blade 324, so that the plow blade 324 can fully and evenly mix the nickel-based metal powder, additive and binder at the bottom position of the mixing cylinder 2, and can spirally guide the nickel-based metal powder, additive and binder during the process of adjusting the angle of the plow blade 324, thereby further improving the mixing effect of the nickel-based metal powder, additive and binder. At the same time, the closing plate 326 can prevent the nickel-based metal powder, additive or binder from getting stuck in the limiting groove 321 and the arc-shaped groove 325.

[0050] Specifically, when the connecting shaft 311 continuously drives the stirring roller 312 to rotate, the stirring roller 312 can continuously mix the nickel-based metal powder, additive and binder. And during the mixing process of the nickel-based metal powder, additive and binder, the mixing cylinder 2 also rotates, and the coordination groove 323 will rotate together with the mixing cylinder 2. When the coordination groove 323 rotates below the pressure rod 322, the pressure rod 322 will move downward under the elastic force of the return spring and make the ball get stuck in the coordination groove 323. At this time, the ball will cooperate with the pressure rod 322 to remove the residual nickel-based metal powder, additive or binder in the coordination groove 323. During the process of the ball cooperating with the pressure rod 322 to remove the nickel-based metal powder, additive and binder, the pressure rod 322 will move downward and drive the closing plate 326 and the telescopic block 327 to move downward. As the telescopic block 327 moves downward, the telescopic block 327 will drive the plow blade 324 to rotate through the fixing rod 328, and after the rotation of the plow blade 324 is completed, the section away from the pressure rod 322 changes from the original upward tilt to the downward tilt. When the plow blade 324 rotates along with the connecting shaft 311, the plow blade 324 will continuously mix the nickel-based metal powder, additive and binder.

[0051] Refer to Figure 3 、 Figure 4 and Figure 8 As shown in FIGS.

[0052] The turning component 33 includes a positioning sleeve 331 fixed to the bottom of the closing cover 31. A nested rod 332 is vertically slidably connected to the positioning sleeve 331. An installation rod 333 is fixed to the bottom of the nested rod 332. A plurality of turning shovel plates 334 are uniformly fixed to the side of the installation rod 333 along the axis direction of the mixing cylinder 2. A guiding structure for driving the turning shovel plates 334 to reciprocate up and down is connected between the installation rod 333 and the inner side wall of the mixing cylinder 2.

[0053] The turning member 33 can turn the part with relatively less nickel-based metal powder, additive and binder. At the same time, the position where the turning member 33 turns the nickel-based metal powder, additive and binder is located at a position that cannot be reached by the plowing member 32 and the stirring roller 312. The nickel-based metal powder, additive and binder are turned comprehensively by the turning member 33, and the nickel-based metal powder, additive and binder on the front side will continue to be mixed as the mixing cylinder 2 rotates. Thus, the mixing range and mixing effect are improved by the provided turning member 33.

[0054] Specifically, when the mixing cylinder 2 rotates, the mixing cylinder 2 will drive the nickel-based metal powder, additive and binder to the position of the mounting rod 333. When the nickel-based metal powder, additive and binder come into contact with the turning shovel plate 334, all three will turn upward along the upper surface of the turning shovel plate 334, so as to achieve the preliminary mixing effect of the turning shovel plate 334. When the track guiding rod 336 moves to the bending section position, the bending section will drive the track guiding rod 336 to move up and down reciprocally. As the track guiding rod 336 moves up and down reciprocally, the mounting rod 333 and the turning shovel plate 334 will move up and down reciprocally together. Due to the up and down reciprocating movement of the turning shovel plate 334, the turning shovel plate 334 shovels the contacting nickel-based metal powder, additive and binder to move up and down synchronously, so that the nickel-based metal powder, additive and binder that continuously rotate with the mixing cylinder 2 are mixed more evenly.

[0055] Refer to Figure 3 , the discharging assembly 22 includes an inclined channel 221 opened on the mixing cylinder 2 and the limiting sleeve 111. A blocking block 222 is slidably connected in the inclined channel 221 along its axial direction. The blocking block 222 is connected to the limiting sleeve 111 through a locking member 223. An outlet 224 is opened in the inclined base 1. The locking member 223 is composed of a positioning pin that slidably penetrates through the blocking block 222 and the limiting sleeve 111 and positioning holes provided on the blocking block 222 and the limiting sleeve 111. The discharging assembly 22 is used for discharging after the nickel-based metal powder, additive and binder are mixed. Specifically, when the nickel-based metal powder, additive and binder are mixed, the positioning pin is removed. At this time, the blocking block 222 will slide down along the inclined channel 221 under the action of gravity until it slides into the outlet 224. Subsequently, as the mixing cylinder 2 continues to rotate, the mixed nickel-based metal powder, additive and binder will fall into the outlet 224 along the inclined channel 221. At this time, it is only necessary to use the collection box at the position of the outlet 224 for quick collection.

[0056] The working steps of the present invention are as follows: In the first step, first, nickel-based metal powder is introduced through the powder inlet 25. Subsequently, the motor 1 211 is controlled to drive the horizontal shaft 212 to rotate. The horizontal shaft 212 continuously drives the driving bevel gear 213 to rotate. Then, the driving bevel gear 213 cooperates with the driven bevel gear 214 to drive the mixing cylinder 2 to continuously rotate. When the mixing cylinder 2 rotates, the nickel-based metal powder therein rotates accordingly. When the powder body rotates with the mixing cylinder 2 to the high position and then naturally drops, automatic mixing is performed.

[0057] In the second step, during the rotation of the mixing cylinder 2, additives and binders are continuously added through the feeding port 24. The additives and binders first fall into the accommodating box 23 that rotates synchronously with the mixing cylinder 2. Part of the materials are evenly sprinkled into the nickel-based metal powder below through the through holes. At the same time, the push rod 345 is triggered to rotate with the accommodating box 23 and trigger the transmission member 344, so that the arc plate 343 is driven to move in the direction opposite to the rotation direction of the mixing cylinder 2 through the transmission member 344. During the movement of the arc plate 343, the push rod 346 will be pushed by the inclined surface of the wedge-shaped guide block 347, driving the wedge-shaped push plate 348 to press down, preventing material agglomeration and accelerating the feeding through the through holes, and achieving multi-point synchronous mixing.

[0058] In the third step, when the additives and binders are mixed with the nickel-based metal powder, the motor 2 314 is controlled to drive the transmission shaft 315 to rotate. The driving pulley and the driven pulley are driven through the transmission belt, so that the connecting shaft 311 drives the stirring roller 312 to stir the mixture. When the mixing cylinder 2 rotates, the coordination groove 323 will rotate with the mixing cylinder 2 to the lower part of the pressure rod 322. At this time, the return spring will push the pressure rod 322 to move downward. At the same time, the ball removes the residual materials in the groove, and the telescopic block 327 is linked to drive the plow blade 324 to rotate through the fixed rod 328, changing the angle of the plow blade 324 to continuously turn over the mixture.

[0059] In the fourth step, during the mixing of the nickel-based metal powder, additives and binders, when the mixing cylinder 2 drives the materials to the installation rod 333, the turning shovel plate 334 will throw the materials upward. And when the trajectory guide rod 336 reciprocates up and down with the bent section, the installation rod 333 will drive the turning shovel plate 334 to move synchronously, and drive the materials to turn over up and down, further improving the uniformity of the materials.

[0060] In the fifth step, after the nickel-based metal powder, additives and binders are mixed, the positioning pin is removed, and the blocking block 222 slides along the inclined channel 221 to the discharge port 224 under the action of gravity. The mixing cylinder 2 continues to rotate, and the mixture falls into the discharge port 224 along the inclined channel 221, and the collection is quickly completed through the collection frame.

[0061] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
