Description

Technical Field

[0001] The present invention relates to the technical field of tantalum-cobalt alloy preparation, and in particular to a solid-liquid mixing and stirring device for preparing tantalum-cobalt alloy. Background Art

[0002] Tungsten-titanium-tantalum-cobalt cemented carbide, also known as general cemented carbide or universal cemented carbide, 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 mixed together through solid-liquid mixing equipment.

[0003] At present, the existing solid-liquid mixing and stirring equipment adds wet mixed powder and glue into it in a quantitative manner and then stirs and mixes them. Since the mixed powder contains moisture after wet grinding, this will increase the viscosity between the mixed powders, and thus increase the resistance of the solid-liquid mixing and stirring equipment to stir and disperse the mixed powders, making it difficult to ensure that the wet mixed powder and glue can be fully stirred and mixed. Summary of the invention

[0004] Based on this, it is necessary to provide a solid-liquid mixing equipment for the preparation of tantalum-cobalt alloy to address the problem that the existing solid-liquid mixing equipment for the preparation of tantalum-cobalt alloy has poor mixing effect and affects the quality of subsequent finished products.

[0005] A solid-liquid mixing and stirring device for preparing tantalum-cobalt alloy comprises a mixing drum, the top of which is fixedly connected to an electric stirrer, the bottom of which penetrates into the interior of the mixing drum, and a dispersed feeding mechanism is installed on the mixing drum.

[0006] Furthermore, the dispersed feeding mechanism includes a feeding barrel fixedly connected to and communicated with the top of the mixing barrel, the top of the feeding barrel is fixedly connected to a servo motor, the end of the servo motor output shaft is fixedly connected to an auger shaft, the bottom of the auger shaft passes through the feeding barrel and extends to the interior of the mixing barrel, the bottom of the auger shaft is fixedly connected to a screen, and the center point of the screen is staggered with the axis of the auger shaft.

[0007] In one of the embodiments, the mixed powder is quantitatively conveyed by an auger shaft and then broken up and separated by rotating a screen. This not only reduces the probability of mixed powder agglomeration inside the mixing drum, but also disperses the mixed powder to avoid the probability of mixed powder piling up and re-agglomeration, thereby improving the stirring and mixing effect of the electric agitator, thereby solving the problem of poor stirring and mixing effect of existing solid-liquid mixing and stirring equipment for the preparation of tantalum-cobalt alloys, which affects the quality of subsequent finished products.

[0008] Furthermore, the dispersed feeding mechanism also includes a quantitative spraying assembly, which includes a storage barrel fixedly connected to the surface of the mixing drum, the surface of the storage barrel fixedly connected and connected to a piston cylinder, the interior of the piston cylinder is slidably connected to a piston block, one end of the piston block is fixedly connected to a guide rod, one end of the guide rod passes through the piston cylinder and is slidably connected to a screen, the surface of the piston cylinder is fixedly connected and connected to a hose, the bottom of the hose is fixedly connected and connected to an atomizing nozzle, a first one-way valve is embedded and installed at the connection between the piston cylinder and the storage barrel and the interior of the hose, the blocking direction of the first one-way valve at the top is the same as the direction from the piston cylinder to the storage barrel, and the blocking direction of the first one-way valve at the bottom is the same as the moving direction from the atomizing nozzle to the hose.

[0009] In one of the embodiments, the quantitative spraying assembly can atomize and spray the glue onto the mixed powder inside the mixing drum under the rotation drive of the screen. This can not only spray the glue quantitatively to improve the contact uniformity between the mixed powder and the glue, but also the atomized spraying method can increase the contact area between the glue and the mixed powder, further improving the stirring and mixing effect of the glue and the mixed powder.

[0010] Furthermore, the dispersed feeding mechanism also includes a guide assembly, which includes a sliding frame fixedly connected to the lower surface of the piston cylinder, one end of the sliding frame is slidably connected to a U-shaped rod, the surface of the U-shaped rod is rotatably connected to a guide sleeve slidably connected to a hose, the surface of the guide sleeve is provided with a spring that is always in a compressed state, and the U-shaped portion of the U-shaped rod is arranged between the piston cylinder and the screen.

[0011] In one embodiment, the guide assembly can actively adjust the spraying angle of the atomizing nozzle under the driving force of the screen rotation, which further expands the contact area between the glue and the mixed powder, and also ensures that the atomizing nozzle can spray glue reciprocatingly.

[0012] Furthermore, an annular groove is provided on the surface of the screen, and one end of the guide rod is rotatably connected to a roller which is slidably connected to the annular groove.

[0013] In one embodiment, the annular groove can not only more stably rotate and adjust the guide rod through the roller, but also prevent the guide rod and the piston block from rotating, so as to improve the sliding sealing between the piston block and the piston cylinder.

[0014] Furthermore, the cross-sectional shape of the bottom of the screen is an arc shape, and the screening portion of the screen is arranged below the annular chute.

[0015] In one embodiment, this can increase the screening range of the screen for the mixed powder, and can also increase the range of rotating and throwing the mixed powder, so that the mixed powder is dispersed more evenly.

[0016] Furthermore, a bottle stopper is inserted into the top opening of the storage barrel, and an air hole is opened on the top of the bottle stopper.

[0017] In one embodiment, this can ensure that the air pressure inside and outside the storage barrel is balanced to ensure that the liquid can be normally adsorbed into the piston cylinder.

[0018] Furthermore, a second one-way valve is embedded in the air hole, and the blocking direction of the second one-way valve is the same as the direction from the storage barrel to the bottle stopper.

[0019] In one of the embodiments, under the premise that the outside air can be sucked into the storage barrel without affecting the negative pressure generated inside the storage barrel, this can prevent the normal circulation of air inside the storage barrel, effectively reducing the probability of the glue being cured or modified due to excessive contact with moisture, oxygen and other substances in the air.

[0020] Furthermore, the number of the springs is two, and the two springs are symmetrically distributed on both sides of the hose.

[0021] In one embodiment, this can improve the repositioning effect of the U-shaped rod.

[0022] Furthermore, the cross-sectional shape of the inner bottom wall of the feed barrel is an inverted cone, and the auger shaft is arranged at the lowest point of the inner bottom wall of the feed barrel; a scraper distributed in a ring is fixedly connected to the surface of the auger shaft, and the inner top wall, side wall and inner bottom wall of the feed barrel are all in contact with the scraper.

[0023] In one embodiment, this can not only preliminarily disperse the mixed powder to reduce the difficulty of subsequent screen rotation dispersion, but also reduce the probability of the mixed powder being retained inside the feed barrel to improve the effective processing rate of the mixed powder.

[0024] The solid-liquid mixing and stirring equipment for preparing tantalum-cobalt alloy quantitatively conveys the mixed powder through the auger shaft, and then breaks it up and separates it through the screen rotation. This can not only reduce the probability of agglomeration of the mixed powder passing through the mixing drum, but also disperse the mixed powder to avoid the probability of the mixed powder piling up and re-agglomerating, so as to improve the stirring and mixing effect of the electric stirrer, thereby solving the problem that the existing solid-liquid mixing and stirring equipment for preparing tantalum-cobalt alloy has poor stirring and mixing effect, which affects the quality of subsequent finished products.

[0025] The quantitative spraying assembly can spray the glue on the mixed powder inside the mixing drum in atomized form under the rotation drive of the screen, which can not only spray the glue quantitatively to improve the contact uniformity between the mixed powder and the glue, but also increase the contact area between the glue and the mixed powder by atomization spraying, further improving the mixing effect of the glue and the mixed powder;

[0026] The guide component can actively adjust the spraying angle of the atomizing nozzle under the driving force of the screen rotation, which further expands the contact area between the glue and the mixed powder, and also ensures that the atomizing nozzle can spray glue reciprocatingly.

[0043] Combine the following Figure 1 - Figure 8 The invention discloses a solid-liquid mixing and stirring device for preparing tantalum-cobalt alloy.

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

[0045] The dispersed feeding mechanism 300 can spray quantitative and dispersed mixed powder and glue into the mixing drum 100, and the electric stirrer 200 rotates and stirs the mixed powder and glue together to improve the formability and plasticity of the mixed powder.

[0046] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the dispersing feeding mechanism 300 includes a feeding barrel 310 fixedly connected and connected to the top of the mixing barrel 100, a servo motor 320 is fixedly connected to the top of the feeding barrel 310, an auger shaft 330 is fixedly connected to the end of the output shaft of the servo motor 320, the bottom of the auger shaft 330 passes through the feeding barrel 310 and extends to the inside of the mixing barrel 100, a screen 340 is fixedly connected to the bottom of the auger shaft 330, the center point of the screen 340 is staggered with the axis of the auger shaft 330, the mixed powder is quantitatively transported by the auger shaft 330, and then the screen 340 is rotated to break up and separate, which can not only reduce the mixing of the mixing barrel 100, but also reduce the mixing of the mixing barrel 100. The probability of the mixed powder inside agglomerating can be reduced, and the mixed powder can also be dispersed to avoid the probability of the mixed powder piling up and re-agglomerating, so as to improve the stirring and mixing effect of the electric stirrer 200, thereby solving the problem that the existing solid-liquid mixing and stirring equipment for preparing tantalum-cobalt alloy has poor stirring and mixing effect, which affects the quality of subsequent finished products; the cross-sectional shape of the inner bottom wall of the feed barrel 310 is an inverted cone, and the auger shaft 330 is arranged at the lowest point of the inner bottom wall of the feed barrel 310; the surface of the auger shaft 330 is fixedly connected with a scraper 370 distributed in an annular shape, and the inner top wall, side wall and inner bottom wall of the feed barrel 310 are all in contact with the scraper 370;

[0047] During the rotation of the auger shaft 330, the auger shaft 330 drives the scraper 370 to rotate synchronously and stir the mixed powder inside the feed barrel 310. This can not only preliminarily disperse the mixed powder to reduce the difficulty of subsequent rotation and dispersion of the screen 340, but also reduce the probability of the mixed powder being retained inside the feed barrel 310, thereby improving the effective processing rate of the mixed powder.

[0048] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the dispersed feeding mechanism 300 also includes a quantitative spraying assembly 350, which includes a storage barrel 351 fixedly connected to the surface of the mixing drum 100, the surface of the storage barrel 351 is fixedly connected and communicated with a piston cylinder 352, the interior of the piston cylinder 352 is slidably 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 passes through the piston cylinder 352 and is slidably connected to 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, and the connection between the piston cylinder 352 and the storage barrel 351 and the hose 356 is fixedly connected. The first one-way valve 357 is embedded in the inside of the tube 355. 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 barrel 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 quantitative spraying assembly 350 can atomize the glue and spray it on the mixed powder inside the mixing drum 100 under the rotation drive of the screen 340. This can not only spray the glue quantitatively to improve the contact uniformity between the mixed powder and the glue, but also the atomized spraying method can increase the contact area between the glue and the mixed powder, further improving the effect of stirring and mixing the glue and the mixed powder.

[0049] An annular groove 341 is provided on the surface of the screen 340, and one end of the guide rod 354 is rotatably connected to a roller 358 that is slidably connected to the annular groove 341. The annular groove 341 can not only more stably rotate and adjust the guide rod 354 through the roller 358, but also prevent the guide rod 354 and the piston block 353 from rotating, so as to improve the sliding sealing between the piston block 353 and the piston cylinder 352; the cross-sectional shape of the bottom of the screen 340 is an arc shape, and the screening part of the screen 340 is arranged below the annular groove 341, which can increase the screening range of the screen 340 for the mixed powder, and also increase the range of rotating and throwing out the mixed powder, so that the mixed powder is dispersed more evenly; storage A bottle plug 359 is inserted into the top opening of the barrel 351, and an air hole 3510 is opened on the top of the bottle plug 359, which can ensure the balance of air pressure inside and outside the storage barrel 351, so as to ensure that the liquid can be normally adsorbed into the piston cylinder 352; a second one-way valve 3511 is embedded in the air hole 3510, and the blocking direction of the second one-way valve 3511 is the same as the direction from the storage barrel 351 to the bottle plug 359. Under the premise that the external air can be sucked into the storage barrel 351 when the negative pressure is generated inside the storage barrel 351, this can prevent the normal circulation of air inside the storage barrel 351, and effectively reduce the probability of the glue being solidified or modified due to excessive contact with moisture, oxygen and other substances in the air;

[0050] Before use, the staff needs to inject a corresponding and quantitative amount of glue into the storage barrel 351. During the rotation of the screen 340, the screen 340 drives the roller 358 to move back and forth through the annular groove 341, and the roller 358 drives the guide rod 354 to move back and forth. The guide rod 354 drives the piston block 353 to move back and forth along the inside of the piston cylinder 352. During the movement of the piston block 353 toward the screen 340, the upper first one-way valve 357 is in a smooth state, and the lower first one-way valve 357 is in a blocked state. At this time, the glue inside the storage barrel 351 is sucked into the piston cylinder 352. 52, when the piston block 353 moves away from the screen 340, the upper first one-way valve 357 is in a blocked state, and the lower first one-way valve 357 is in a free state. The glue inside the piston cylinder 352 is squeezed into the hose 355, and the glue is atomized and sprayed on the mixed powder inside the mixing drum 100 through the atomizing nozzle 356. This can not only spray the glue quantitatively to improve the contact uniformity between the mixed powder and the glue, but also the atomizing spraying method can increase the contact area between the glue and the mixed powder, further improving the effect of stirring and mixing the glue and the mixed powder.

[0051] like Figure 4 , Figure 7 and Figure 8 As shown, the dispersed feeding mechanism 300 also includes a guide assembly 360, which includes a slide frame 361 fixedly connected to the lower surface of the piston cylinder 352, one end of the slide frame 361 is slidably connected to a U-shaped rod 362, the surface of the U-shaped rod 362 is rotatably connected to a guide sleeve 363 slidably connected to the hose 355, and the surface of the guide sleeve 363 is sleeved with a spring 364 that is always in a compressed state, and the U-shaped portion 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 reciprocatingly; the number of the 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 squeezes the 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 is away from the U-shaped rod 362, the spring 364 can also gradually reset the U-shaped rod 362, which enables the atomizing nozzle 356 to spray glue reciprocatingly.

[0053] Working principle: After the staff puts the wet-ground mixed powder into the feed barrel 310, the staff manually turns on the servo motor 320, which drives the auger shaft 330 to rotate. The auger shaft 330 spirally conveys a certain amount of mixed powder into the screen 340. At this time, the screen 340 can filter out the agglomerates in the mixed powder whose diameter is larger than the mesh aperture, so that the loose mixed powder passes through the screen 340 into the interior of the mixing barrel 100. At the same time, the auger shaft 330 drives the screen 340 to rotate during the rotation. The mesh 340 rotates, and the screen 340 drives the lumps retained inside it to rotate. The lumps collide with the inner wall of the screen 340 under the action of the rotating centrifugal force, which can break up the lumps, so that the mixed powder with smaller particle size can smoothly pass through the screen 340 into the mixing drum 100, and because the axis line of the auger shaft 330 intersects with the center point of the screen 340, this can increase the rotation radius of the screen 340, thereby increasing the rotation centrifugal force of the lumps, so as to increase the probability of the lumps being broken up.

[0054] It should be noted that the electric agitator 200, servo motor 320, auger shaft 330, first one-way valve 357 and second one-way valve 3511 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electric agitator 200 and the servo motor 320 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0055] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
