[0001] The present application relates to the technical field of tantalum-cobalt alloy preparation, and particularly relates to a solid-liquid mixing and stirring device for tantalum-cobalt alloy preparation. BACKGROUND

[0002] Tungsten-titanium-tantalum-cobalt hard alloy, also known as general hard alloy or universal hard alloy, is a high-temperature-resistant material composed of tungsten carbide powder, titanium carbide powder, tantalum carbide powder and metal cobalt powder. In order to improve the formability and plasticity of the powder, the mixed powder needs to be mixed with glue after wet grinding and stirred uniformly by a solid-liquid mixing and stirring device.

[0003] At present, the existing solid-liquid mixing and stirring device adds the wet mixed powder and glue into the device quantitatively and then stirs them uniformly. Since the mixed powder contains water after wet grinding, the viscosity between the mixed powder is increased, which increases the resistance of the solid-liquid mixing and stirring device to stir and disperse the mixed powder, and it is difficult to ensure that the wet mixed powder and glue can be fully stirred and mixed uniformly.

[0043] The present application will be described below with reference to the drawings. Figure 1 - Figure 8 A solid-liquid mixing and stirring device for preparing a tantalum-cobalt alloy is described.

[0044] In one embodiment, a solid-liquid mixing and stirring device for preparing a tantalum-cobalt alloy includes a stirring cylinder 100, a top of the stirring cylinder 100 is fixedly connected with an electric stirrer 200, a bottom of the electric stirrer 200 penetrates into an inside of the stirring cylinder 100, and the stirring cylinder 100 is provided with a dispersion feeding mechanism 300;

[0045] The dispersion feeding mechanism 300 can spray the quantitatively and dispersedly mixed powder and glue liquid into the stirring cylinder 100, and the electric stirrer 200 can rotate and stir the mixed powder and the glue liquid together to improve the formability and plasticity of the mixed powder.

[0046] As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the dispersion feeding mechanism 300 includes a feeding cylinder 310 fixedly connected and communicated with the top of the stirring cylinder 100, the top of the feeding cylinder 310 is fixedly connected with a servo motor 320, the end of the output shaft of the servo motor 320 is fixedly connected with an auger shaft 330, the bottom of the auger shaft 330 penetrates through the feeding cylinder 310 and extends to the inside of the stirring cylinder 100, the bottom of the auger shaft 330 is fixedly connected with a screen 340, the center point of the screen 340 intersects with the axis of the auger shaft 330, the mixed powder is quantitatively conveyed through the auger shaft 330, and then is separated and dispersed by the rotating screen 340, which not only can reduce the probability of caking of the mixed powder passing through the inside of the stirring cylinder 100, but also can disperse the mixed powder to avoid the probability of re-caking of the mixed powder accumulated together, so as to improve the stirring and mixing effect of the electric mixer 200, thereby solving the problem of poor stirring and mixing effect of the existing solid-liquid mixing and stirring equipment for preparing tantalum-cobalt alloy, which affects the quality of the subsequent finished product.

[0047] In the process of rotating the auger shaft 330, the auger shaft 330 drives the scraper 370 to rotate synchronously to stir the mixed powder in the inside of the feeding cylinder 310, which not only can preliminarily disperse the mixed powder to reduce the difficulty of subsequent rotation and dispersion of the screen 340, but also can reduce the probability of the mixed powder remaining in the inside of the feeding cylinder 310, so as to improve the effective processing rate of the mixed powder.

[0048] As shown in the drawings, Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the dispersion feeding mechanism 300 further comprises a metering spraying assembly 350, which comprises a storage cylinder 351 fixedly connected to the surface of the mixing drum 100, the surface of the storage cylinder 351 is fixedly connected and communicated with a piston cylinder 352, the inside of the piston cylinder 352 is slidingly connected with a piston block 353, one end of the piston block 353 is fixedly connected with a guide rod 354, one end of the guide rod 354 penetrates out of the piston cylinder 352 and is slidingly connected with the screen 340, the surface of the piston cylinder 352 is fixedly connected and communicated with a hose 355, the bottom of the hose 355 is fixedly connected and communicated with an atomizing nozzle 356, the communication between the piston cylinder 352 and the storage cylinder 351 and the inside of the hose 355 are both embeddedly installed with a first one-way valve 357, the blocking direction of the upper first one-way valve 357 is the same as the direction from the piston cylinder 352 to the storage cylinder 351, and the blocking direction of the lower first one-way valve 357 is the same as the moving direction from the atomizing nozzle 356 to the hose 355, the metering spraying assembly 350 can atomize and spray the glue on the mixed powder inside the mixing drum 100 under the rotary driving of the screen 340, which not only can quantitatively spray the glue to improve the contact uniformity of the mixed powder and the glue, but also can increase the contact area of the glue and the mixed powder in the atomizing spraying mode, further improving the effect of mixing and uniformity of the glue and the mixed powder.

[0049] The surface of the screen 340 is provided with an annular sliding groove 341, one end of the guide rod 354 is rotatably connected with a roller 358 slidingly connected with the annular sliding groove 341, the annular sliding groove 341 can not only more stably rotate and adjust the guide rod 354, but also can prevent the guide rod 354 and the piston block 353 from rotating to improve the sliding sealing property between the piston block 353 and the piston cylinder 352; the cross-sectional shape of the bottom of the screen 340 is arc-shaped, and the screening part of the screen 340 is arranged below the annular sliding groove 341, which can increase the screening range of the mixed powder by the screen 340 and also can increase the range of the mixed powder being rotated and thrown out, so that the dispersion of the mixed powder is more uniform; the top of the storage cylinder 351 is inserted with a bottle plug 359, the top of the bottle plug 359 is provided with an air hole 3510, which can ensure the balance of the air pressure inside and outside the storage cylinder 351 to ensure that the liquid can be normally absorbed into the piston cylinder 352; the inside of the air hole 3510 is embeddedly installed with a second one-way valve 3511, the blocking direction of the second one-way valve 3511 is the same as the direction from the storage cylinder 351 to the bottle plug 359, under the premise that the air outside can be sucked into the inside of the storage cylinder 351 without affecting the negative pressure generated in the inside of the storage cylinder 351, which can prevent the normal circulation of the air in the inside of the storage cylinder 351, effectively reducing the probability of the glue being solidified or modified due to excessive contact with water, oxygen and other substances in the air;

[0050] Before use, the staff needs to inject corresponding and quantitative glue into the storage barrel 351. During the rotation of the screen 340, the screen 340 drives the roller 358 to reciprocate through the annular sliding groove 341, the roller 358 drives the guide rod 354 to reciprocate, and the guide rod 354 drives the piston block 353 to reciprocate along the inside of the piston cylinder 352. During the movement of the piston block 353 to the direction close to the screen 340, the upper first one-way valve 357 is in an open state, and the lower first one-way valve 357 is in a blocking state. At this time, the glue in the storage barrel 351 is sucked into the piston cylinder 352. During the movement of the piston block 353 to the direction away from the screen 340, the upper first one-way valve 357 is in a blocking state, and the lower first one-way valve 357 is in an open state. The glue in the piston cylinder 352 is squeezed into the hose 355, and the glue is atomized and sprayed on the mixed powder in the stirring drum 100 through the atomizing nozzle 356. This not only can quantitatively spray glue to improve the uniformity of the contact between the mixed powder and the glue, but also can increase the contact area between the glue and the mixed powder by atomizing and spraying, further improving the effect of mixing and stirring the glue and the mixed powder.

[0051] As shown in Figure 4 , Figure 7 and Figure 8 , the dispersion feeding mechanism 300 further comprises a guide assembly 360, which comprises a sliding frame 361 fixedly connected to the lower surface of the piston cylinder 352. One end of the sliding frame 361 is slidingly connected with a U-shaped rod 362. The surface of the U-shaped rod 362 is rotatably connected with a guide sleeve 363 slidingly connected with the hose 355. The surface of the guide sleeve 363 is sleeved with a spring 364 always in a compressed state. The U-shaped part of the U-shaped rod 362 is arranged between the piston cylinder 352 and the screen 340. The guide assembly 360 can actively adjust the spraying angle of the atomizing nozzle 356 under the driving force of the rotation of the screen 340, which further expands the contact area between the glue and the mixed powder, and also ensures that the atomizing nozzle 356 can spray glue cyclically and reciprocally. The number of springs 364 is two, and the two springs 364 are symmetrically distributed on both sides of the hose 355, which can improve the resetting effect of the U-shaped rod 362.

[0052] During the rotation of the screen 340, the screen 340 continuously presses the circular arc surface of the U-shaped rod 362. The U-shaped rod 362 drives the hose 355 to rotate through the guide sleeve 363. The hose 355 drives the atomizing nozzle 356 to change the spraying range of the glue, which further expands the contact area between the glue and the mixed powder. When the screen 340 moves away from the U-shaped rod 362, the spring 364 can also gradually reset the U-shaped rod 362, which can make the atomizing nozzle 356 spray glue cyclically and reciprocally.

[0053] Working principle: when the worker puts the mixed powder after wet grinding into the feeding cylinder 310, the worker manually starts the servo motor 320, the servo motor 320 drives the auger shaft 330 to rotate, the auger shaft 330 spirally conveys the quantitative mixed powder into the screen 340, at this time the screen 340 can filter out the lumps in the mixed powder whose diameter is greater than the mesh aperture of the screen, so that the loose mixed powder passes through the screen 340 into the inside of the stirring cylinder 100, at the same time the auger shaft 330 drives the screen 340 to rotate in the process of rotation, the screen 340 drives the lumps retained in the inside to rotate, the lumps collide with the inner wall of the screen 340 under the action of the rotational centrifugal force, which can scatter the lumps, so that the mixed powder with smaller particle size can smoothly pass through the screen 340 into the stirring cylinder 100, and since the axis of the auger shaft 330 intersects with the center point of the screen 340, this can increase the rotational radius of the screen 340, and further increase the rotational centrifugal force of the lumps, so as to increase the probability of scattering the lumps.

[0054] It should be noted that the electric mixer 200, the servo motor 320, the auger shaft 330, the first one-way valve 357 and the second one-way valve 3511 in the above description are all relatively mature devices in the prior art, and the specific model can be selected according to actual needs, and the power supply of the electric mixer 200 and the servo motor 320 can be built-in power supply or mains power supply, and the specific power supply mode is selected as appropriate, which will not be described here.

[0055] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0056] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
