Description

Technical Field

[0001] The invention relates to the technical field of gold material production equipment, and in particular to a vibration screening device for producing cobalt-chromium-molybdenum alloy powder material and a use method thereof. Background Art

[0002] Alloys are substances with metallic properties that are synthesized by two or more metals and metals or non-metals through a certain method. The formation of alloys often improves the properties of the elements alone. For example, the strength of steel is greater than that of its main component iron. The physical properties of alloys, such as density, reactivity, Young's modulus, electrical conductivity and thermal conductivity, may be similar to those of the constituent elements of the alloy, but the tensile strength and shear strength of the alloy are usually very different from the properties of the constituent elements.

[0003] Cobalt-chromium-molybdenum alloy powder has fine particles, which are easily squeezed into each other to form agglomerates during the screening process. Screen blockage will slow down the speed at which materials pass through the sieve holes, or even prevent them from passing normally, resulting in reduced screening accuracy. Alloy powder that meets the particle size requirements cannot be effectively separated, affecting product quality. It will also increase the energy consumption and operating time of the equipment and reduce production efficiency. Summary of the invention

[0019] The present invention has the following beneficial effects:

[0020] (1)A vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials. The alloy powder to be screened is placed in the feeding box. The powder will enter the arc plate in the screening box from the feeding box. The driving motor is started, and the driving motor drives the rotating shaft to rotate. The rotating shaft drives the scraper to rotate. The scraper rotates to scrape up and throw out the powder on the arc plate. When the scraper leaves the arc plate, the powder will hit the impact block under the action of centrifugal force. The impact block will disperse the agglomerates in the powder. At this time, the powder will be distributed on the medium filter plate due to centrifugal force and impact force, ensuring that there are no agglomerated powders during the screening process, thereby improving the quality of the screened powder. During the rotation of the rotating shaft, several fan blades will also be driven to rotate. The fan blades will generate a suction force. The suction force will suck air through the suction pipe into several micro-filters on the side of the powder collection drawer. The dust in the screening box will move towards the powder collection drawer, sucking the smoke and dust and fine-particle alloy powder generated during the screening process into the powder collection drawer. As the negative pressure in the screening box increases, the suction force will pull the U-shaped box downward. When the ventilation holes on the U-shaped box leave the rectangular groove, the device is in a ventilation state at this time, and the smoke and dust powder in the device can be continuously collected into the powder collection drawer;

[0021] (2)A vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials. During the rotation of the scraper, it will contact the conical round rod. Due to the elastic force of the transmission spring being greater than that of the stirring spring, the conical round rod will drive the stirring rod to move towards the collection box. At this time, the stirring spring undergoes compressive deformation. The stirring of the stirring rod will continuously feed the powder in the feeding box into the screening box, preventing blockage and affecting the normal screening of the powder. When the stirring spring is compressed to its maximum state, the conical round rod will slide into the circular cavity under the action of the scraper. At this time, the transmission spring will also undergo compressive deformation. When the scraper leaves the conical round rod, the conical round rod and the stirring rod will respectively return to their original positions under the elastic forces of the transmission spring and the stirring spring, preparing for the next stirring;

[0022] (3)A vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials. During the rotation of the scraper, it will contact the T-shaped block. The T-shaped block will descend. At this time, the telescopic spring undergoes tensile deformation. The descent of the T-shaped block will drive the isosceles trapezoidal plate to descend. The isosceles trapezoidal plate will drive the L-shaped contact block to descend. The L-shaped contact block will drive the medium filter plate and the dust filter plate to rotate a small distance around the rotating rod and adjust the angle downward. At this time, the vibration spring II undergoes tensile deformation. When the vibration spring II is stretched to its maximum extent, the L-shaped contact block will no longer move. At this time, the isosceles trapezoidal plate will slide into the mating groove. At this time, the mating spring undergoes compressive deformation. When the isosceles trapezoidal plate leaves the L-shaped contact block, the vibration spring II will drive the medium filter plate and the dust filter plate to recover under the elastic force and hit the triangular block to vibrate, making the powder on the medium filter plate and the dust filter plate more dispersed;

[0023] (4) The present invention provides a vibration screening device for the production of cobalt-chromium-molybdenum alloy powder materials. During the continuous descent of the T-shaped block, the isosceles trapezoidal plate will pop out again under the elastic force of the matching spring, and the isosceles trapezoidal plate will contact the special-shaped rod, and under the action of the inclined surface of the special-shaped rod, the special-shaped rod will move away from the isosceles trapezoidal plate. The special-shaped rod will drive the medium-sized filter plate and the dust filter plate to move at the same time. At this time, the vibration spring close to the special-shaped rod will undergo compression deformation, and the vibration spring away from the special-shaped rod will undergo tensile deformation. When the isosceles trapezoidal plate scraper leaves After the T-shaped block is installed, the T-shaped block will rise under the action of the telescopic spring, and the T-shaped block will drive the isosceles trapezoidal plate to leave the special-shaped rod. At this time, the connecting block will drive the medium filter plate and the dust filter plate to shake left and right under the elastic force of the two vibration springs. The left and right shaking will cause the larger unqualified alloy particles on the medium filter plate to shake into the first cavity, and the qualified alloy powder that falls from the medium filter plate to the dust filter plate will enter the second cavity, and the remaining smaller particles of alloy powder will enter the powder collection drawer, completing the screening and collection of powders of different sizes.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] As the negative pressure in the screening box 1 becomes larger and larger, at this time, the suction force will pull the U-shaped box 605 downward. After the ventilation holes 606 on the U-shaped box 605 leave the rectangular groove 603, the device is in a ventilation state at this time, and the soot powder in the device can be continuously collected into the powder collection drawer 505 at this time.

[0043] As Figure 4As shown, two stirring mechanisms 7 are arranged in the discharge box 601, and the stirring mechanism 7 includes a stirring rod 701 slidably installed in the discharge box 601, and a rectangular slide bar 702 is slidably installed on the discharge box 601, the rectangular slide bar 702 penetrates the stirring rod 701 and the discharge box 601, and is slidably connected with the discharge box 601 and the stirring rod 701, a fixed sleeve 703 is fixed on the rectangular slide bar 702, and a stirring spring 704 is sleeved on the rectangular slide bar 702, the left end of the stirring spring 704 is fixedly connected to the fixed sleeve 703, and the right end of the stirring spring 704 is fixedly connected to the discharge box 601.

[0044] The stirring spring 704 is compressed and deformed, and the stirring of the stirring rod 701 causes the powder in the discharge box 601 to continuously enter the screening box 1, thereby avoiding blockage and affecting the normal screening of the powder.

[0046] During the rotation of the scraper 4 , it will contact the conical rod 707 . Since the elastic force of the transmission spring 706 is greater than the stirring spring 704 , the conical rod 707 will drive the stirring rod 701 to move towards the collecting box 508 .

[0047] like Figure 8 As shown, the vibration mechanism 8 in the screening box 1 includes a medium filter plate 801 and a dust filter plate 802 arranged in the screening box 1, a connecting block 803 is fixedly installed at the bottom of the medium filter plate 801, and the bottom end of the connecting block 803 is fixedly connected to the dust filter plate 802, and the left ends of the medium filter plate 801 and the dust filter plate 802 extend into the first cavity 509 and the second cavity 510 respectively, and a rotating rod 804 is rotatably installed in the screening box 1, the rotating rod 804 passes through the connecting block 803 and is slidably connected to the connecting block 803, and two vibration springs 805 are sleeved on the rotating rod 804, and the ends of the two vibration springs 805 that are close to each other are fixedly connected to the connecting block 803, and the ends of the two vibration springs 805 that are away from each other are fixedly connected to the screening box 1.

[0048] The connecting block 803 will drive the medium filter plate 801 and the dust filter plate 802 to shake left and right under the elastic force of the two vibration springs 805. The left and right shaking will cause the larger unqualified alloy particles on the medium filter plate 801 to shake into the first cavity 509, and the qualified alloy powder that falls from the medium filter plate 801 to the dust filter plate 802 will enter the second cavity 510, and the remaining smaller particles of alloy powder will enter the powder collection drawer 505, completing the screening and collection of powders of different sizes.

[0049] like Figure 6 As shown, a mating mechanism 9 is provided in the T-shaped block 608, and the mating mechanism 9 includes a mating groove 901 opened in the T-shaped block 608, a mating spring 902 is fixedly installed on the right inner wall of the mating groove 901, an isosceles trapezoidal plate 903 is fixedly installed on the left side of the mating spring 902, and the left end of the isosceles trapezoidal plate 903 extends to the outside of the mating groove 901, and an L-shaped contact block 904 is fixedly installed on the bottom of the dust filter plate 802.

[0050] The descent of T-shaped block 608 will drive the isosceles trapezoidal plate 903 to descend, the isosceles trapezoidal plate 903 will drive the L-shaped contact block 904 to descend, and the L-shaped contact block 904 will drive the medium filter plate 801 and the dust filter plate 802 to rotate a short distance around the rotating rod 804 at the same time and adjust the angle downward.

[0051] like Fig. 9 As shown, a special-shaped rod 905 is fixedly installed at the bottom of the connecting block 803, an I-shaped plate 906 is fixedly installed in the screening box 1, the I-shaped plate 906 passes through the dust filter plate 802 and is slidably connected to the dust filter plate 802, and two vibration springs 907 are fixedly installed on the top of the I-shaped plate 906, and the top ends of the two vibration springs 907 are fixedly connected to the two triangular blocks 507 respectively.

[0052] When the vibration spring 907 is stretched to the maximum extent, the L-shaped contact block 904 no longer moves. At this time, the isosceles trapezoidal plate 903 will slide into the matching groove 901. At this time, the matching spring 902 is compressed and deformed. When the isosceles trapezoidal plate 903 leaves the L-shaped contact block 904, the vibration spring 907 will drive the medium filter plate 801 and the dust filter plate 802 to recover under the action of elastic force and hit the triangular block 507 to vibrate, so that the powder on the medium filter plate 801 and the dust filter plate 802 is more dispersed.

[0053] like Figure 1 - Fig.10 As shown, a method for vibrating screening equipment for producing cobalt-chromium-molybdenum alloy powder material, the method steps are as follows:

[0054] S1: Break up the clumps and eliminate the smoke and dust;

[0055] S2: Prevent powder clogging;

[0056] S3: Up and down vibration powder screening;

[0057] S4: Left and right vibration classification, screening and collection.

[0058] Put the alloy powder to be screened into the feeding box 601. The powder will enter from the feeding box 601 onto the arc-shaped plate 501 in the screening box 1. Start the driving motor 2. The driving motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the scraper 4 to rotate. The rotating scraper 4 scrapes up the powder on the arc-shaped plate 501 and throws it out. When the scraper 4 leaves the arc-shaped plate 501, the powder will hit the impact block 502 under the action of centrifugal force. The impact block 502 will disperse the agglomerates in the powder. At this time, the powder will be distributed on the medium filter plate 801 due to centrifugal force and impact force, ensuring that there are no agglomerated powders during the screening process, thereby improving the quality of the screened powder. During the rotation of the rotating shaft 3, several fan blades 512 will also be driven to rotate. The fan blades 512 will generate a suction force. The suction force will suck air through the suction pipe 513 into several micro-filters 506 on the side of the powder collection drawer 505. The dust in the screening box 1 will move towards the powder collection drawer 505, sucking the smoke and dust and fine particle alloy powder generated during the screening process into the powder collection drawer 505. As the negative pressure in the screening box 1 increases, the suction force will pull the U-shaped box 605 downward. When the ventilation holes 606 on the U-shaped box 605 leave the rectangular groove 603, the device is in a ventilation state at this time, and the smoke and dust powder in the device can be continuously collected into the powder collection drawer 505; during the rotation of the scraper 4, it will contact the conical round rod 707. Since the elastic force of the transmission spring 706 is greater than that of the stirring spring 704, the conical round rod 707 will drive the stirring rod 701 to move towards the collection box 508. At this time, the stirring spring 704 undergoes a compressive deformation. The stirring of the stirring rod 701 will continuously feed the powder in the feeding box 601 into the screening box 1, preventing blockage and affecting the normal screening of the powder. When the stirring spring 704 is compressed to the maximum state, the conical round rod 707 will slide into the circular cavity 705 under the action of the scraper 4. At this time, the transmission spring 706 will also undergo a compressive deformation. When the scraper 4 leaves the conical round rod 707, the conical round rod 707 and the stirring rod 701 will respectively return to their original positions under the elastic forces of the transmission spring 706 and the stirring spring 704, preparing for the next stirring;

[0059] During the rotation of the scraper 4, it will contact the T-shaped block 608, and the T-shaped block 608 will drop. At this time, the telescopic spring 609 will be stretched and deformed. The drop of the T-shaped block 608 will drive the isosceles trapezoidal plate 903 to drop, and the isosceles trapezoidal plate 903 will drive the L-shaped contact block 904 to drop. The L-shaped contact block 904 will drive the medium filter plate 801 and the dust filter plate 802 to rotate a short distance around the rotating rod 804 at the same time and adjust the angle downward. At this time, the vibration spring 907 will be stretched and deformed. When the vibration spring 907 is stretched to the maximum extent, the L-shaped contact block 904 will no longer move. The isosceles trapezoidal plate 903 will slide into the matching groove 901, and the matching spring 902 will be compressed and deformed. When the isosceles trapezoidal plate 903 leaves the L-shaped contact block 904, the vibration spring 907 will drive the medium filter plate 801 and the dust filter plate 802 to recover and hit the triangular block 507 to vibrate, so that the powder on the medium filter plate 801 and the dust filter plate 802 is more dispersed; during the continuous descent of the T-shaped block 608, the isosceles trapezoidal plate 903 will pop out again under the elastic force of the matching spring 902, and the isosceles trapezoidal plate 903 will be 3 will contact the special-shaped rod 905, and under the action of the inclined surface of the special-shaped rod 905, the special-shaped rod 905 will move away from the isosceles trapezoidal plate 903. The special-shaped rod 905 will drive the medium filter plate 801 and the dust filter plate 802 to move at the same time. At this time, the vibration spring 805 close to the special-shaped rod 905 will be compressed and deformed, and the vibration spring 805 away from the special-shaped rod 905 will be stretched. After the scraper 4 of the isosceles trapezoidal plate 903 leaves the T-shaped block 608, the T-shaped block 608 will rise under the action of the telescopic spring 609, and the T-shaped block 608 drives The isosceles trapezoidal plate 903 leaves the special-shaped rod 905.
