Description

Technical Field

[0001] This invention relates to the field of gold material production equipment technology, specifically to a vibration screening device for the production of cobalt-chromium-molybdenum alloy powder materials and its usage method. Background Technology

[0002] An alloy is a substance with metallic properties synthesized from two or more metals and metals or nonmetals through a certain method. The formation of alloys often improves the properties of the elemental form; for example, the strength of steel is greater than that of its main constituent element, iron. The physical properties of an alloy, such as density, reactivity, Young's modulus, electrical conductivity, and thermal conductivity, may be similar to those of its constituent elements. However, the tensile strength and shear strength of an alloy are usually quite different from the properties of its constituent elements.

[0003] Cobalt-chromium-molybdenum alloy powder particles are fine and easily aggregate during screening. Screen blockage slows down the material's passage through the screen holes or even prevents it from passing through normally, resulting in reduced screening accuracy. This makes it impossible to effectively separate alloy powder that meets the particle size requirements, affecting product quality. It also increases the energy consumption and operating time of the equipment, reducing production efficiency. Summary of the Invention

[0014] Furthermore, the method for using a vibration screening device for producing cobalt-chromium-molybdenum alloy powder materials comprises the following steps:

[0015] S1: Breaks up clumps and eliminates smoke and dust;

[0016] S2: Prevents powder from clogging;

[0017] S3: Up-and-down vibrating powder sieving;

[0018] S4: Left and right vibration sorting and sieving collection.

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

[0020] (1) The present invention provides a vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials. The alloy powder to be screened is placed in a feeding box. The powder enters the arc plate inside the screening box from the feeding box. The drive motor is started, and the drive motor drives the rotating shaft to rotate. The rotating shaft drives the scraper to rotate. The rotating scraper scrapes up the powder on the arc plate and throws it out. When the scraper leaves the arc plate, the powder will impact the impact block under the action of centrifugal force. The impact block will break up the clumps in the powder. At this time, the powder will be dispersed on the medium filter plate due to centrifugal force and impact force, ensuring that there are no clumps of powder during the screening process, thereby improving the efficiency. The high-quality screening of powder, during the rotation of the shaft, also drives several fan blades to rotate. The fan blades generate suction force, which is used to draw air through the suction pipe to several micro-filter holes on the side of the powder collection tray. The dust in the screening box moves closer to the powder collection tray, and the smoke and fine alloy powder particles generated during the screening process are sucked into the powder collection tray. As the negative pressure in the screening box increases, the suction will pull the C-shaped box downward. After the ventilation holes on the C-shaped box leave the rectangular groove, the device is in a ventilation state. At this time, the smoke and dust powder in the device can be continuously collected into the powder collection tray.

[0021] (2) The present invention provides a vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials. During the rotation of the scraper, it will come into contact with the conical rod. Since the elastic force of the transmission spring is greater than that of the stirring spring, the conical rod will drive the stirring rod to move closer to the collection box. At this time, the stirring spring will undergo compression deformation. The stirring of the stirring rod will cause the powder in the discharge box to continuously enter the screening box, avoiding blockage and affecting the normal screening of the powder. When the stirring spring is compressed to the maximum state, the conical rod will slide into the circular cavity under the action of the scraper. At this time, the transmission spring will also undergo compression deformation. When the scraper leaves the conical rod, the conical rod and the stirring rod will be reset under the action of the elastic force of the transmission spring and the stirring spring, respectively, to prepare for the next stirring.

[0022] (3) The present invention provides a vibration 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 and the T-shaped block will descend. At this time, the extension spring will be stretched and deformed. 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 around the rotating rod for a short distance and adjust the angle downward. At this time, the vibration spring will be stretched and deformed. When the vibration spring is stretched to the 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 will be compressed and deformed. When the isosceles trapezoidal plate leaves the L-shaped contact block, the vibration spring will drive the medium filter plate and the dust filter plate to recover under the action of elasticity and hit the triangular block to vibrate, so that the powder on the medium filter plate and the dust filter plate is more dispersed.

[0023] (4) In the vibrating 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 spring. The isosceles trapezoidal plate will contact the irregular rod and, under the action of the inclined surface of the irregular rod, drive the irregular rod to move away from the isosceles trapezoidal plate. The irregular rod will drive the medium filter plate and the dust filter plate to move simultaneously. At this time, the vibration spring one near the irregular rod will undergo compression deformation, and the vibration spring one away from the irregular rod will undergo tensile deformation. When the scraper of the isosceles trapezoidal plate leaves After the T-shaped block is in place, it will rise under the action of the telescopic spring. The T-shaped block will drive the isosceles trapezoidal plate away from the irregular rod. At this time, the connecting block will cause the medium filter plate and the dust filter plate to sway left and right under the elastic force of the two vibration springs. The left and right swaying will cause the larger unqualified alloy particles on the medium filter plate to fall into the first chamber. The qualified alloy powder that falls from the medium filter plate to the dust filter plate will enter the second chamber. The remaining smaller alloy powder particles will enter the powder collection drawer, thus completing the screening and collection of powders of different sizes.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 - Figure 10 As shown, this invention is a vibrating screening device for the production of cobalt-chromium-molybdenum alloy powder materials, including a screening box 1, a drive motor 2 fixedly mounted on the front of the screening box 1, a rotating shaft 3 rotatably mounted inside the screening box 1, the rotating shaft 3 penetrating the screening box 1, the front end of the rotating shaft 3 being fixedly connected to the output shaft of the drive motor 2, and a scraper 4 fixedly sleeved on the rotating shaft 3, and further including:

[0040] The anti-clogging mechanism 5 includes an arc-shaped plate 501 fixedly installed inside the screening box 1, an impact block 502 fixedly installed on the top inner wall of the screening box 1, the impact block 502 having several impact grooves 503, the arc-shaped plate 501 having several filter holes 504, a powder collection tray 505 slidably installed inside the screening box 1, the front of the powder collection tray 505 extending outside the screening box 1, the back inner wall of the powder collection tray 505 having several micro filter holes 506, and triangular blocks 507 fixedly installed on the front and back inner walls of the screening box 1 respectively. A collection box 508 is fixedly installed on the left side of the screening box 1. The collection box 508 has a first cavity 509 and a second cavity 510. Both the first cavity 509 and the second cavity 510 are connected to the screening box 1. A bellows 511 is fixedly installed on the back of the screening box 1. The end of the rotating shaft 3 extends into the bellows 511 and is rotatably connected to the bellows 511. Several fan blades 512 are fixedly installed on the rotating shaft 3. A suction pipe 513 is fixedly installed on the outer wall of the bellows 511. The bottom end of the suction pipe 513 is connected to the screening box 1 and is close to several micro filter holes 506.

[0041] like Figure 4 and Figure 5 As shown, a sealing mechanism 6 is provided on the top of the screening box 1. The sealing mechanism 6 includes a discharge box 601 fixedly installed on the top of the screening box 1. A closing plate 602 is hinged to the top of the discharge box 601. A rectangular groove 603 is provided at the bottom of the closing plate 602. Several through holes 604 are provided at the top of the closing plate 602. The several through holes 604 communicate with the rectangular groove 603. A U-shaped box 605 is slidably installed in the rectangular groove 603. The outer wall of the U-shaped box 605 has... Several ventilation holes 606 are provided. A sealing spring 607 is fixedly installed on the bottom inner wall of the U-shaped box 605. The top end of the sealing spring 607 is fixedly connected to the top inner wall of the rectangular groove 603. A T-shaped block 608 is slidably installed on the arc plate 501. The T-shaped block 608 penetrates the arc plate 501. A telescopic spring 609 is fixedly installed on the outer wall of the arc plate 501. The bottom end of the telescopic spring 609 is fixedly connected to the T-shaped block 608. The T-shaped block 608 penetrates the telescopic spring 609.

[0042] As the negative pressure inside the screening box 1 increases, the suction will pull the U-shaped box 605 downward. After the ventilation hole 606 on the U-shaped box 605 leaves the rectangular groove 603, the device is in a ventilation state. At this time, the dust and powder inside the device can be continuously collected into the powder collection tray 505.

[0043] like Figure 4As shown, two agitation mechanisms 7 are provided inside the feeding box 601. The agitation mechanism 7 includes an agitation rod 701 slidably installed inside the feeding box 601. A rectangular slide rod 702 is slidably installed on the feeding box 601. The rectangular slide rod 702 passes through the agitation rod 701 and the feeding box 601 and is slidably connected to the feeding box 601 and the agitation rod 701. A fixing sleeve 703 is fixedly sleeved on the rectangular slide rod 702. An agitation spring 704 is sleeved on the rectangular slide rod 702. The left end of the agitation spring 704 is fixedly connected to the fixing sleeve 703, and the right end of the agitation spring 704 is fixedly connected to the feeding box 601.

[0044] The stirring spring 704 is compressed and deformed, and the stirring rod 701 stirs the powder in the discharge box 601 to continuously enter the screening box 1, so as to avoid blockage and affect the normal screening of powder.

[0045] like Figure 7 As shown, a circular cavity 705 is provided inside the stirring rod 701. A transmission spring 706 is fixedly installed on the top inner wall of the circular cavity 705. A conical rod 707 is fixedly installed at the bottom end of the transmission spring 706. The bottom end of the conical rod 707 extends into the screening box 1.

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

[0047] like Figure 8 As shown, a vibration mechanism 8 is provided inside the screening box 1. The vibration mechanism 8 includes a medium filter plate 801 and a dust filter plate 802 disposed inside the screening box 1. A connecting block 803 is fixedly installed at the bottom of the medium filter plate 801. The bottom end of the connecting block 803 is fixedly connected to the dust filter plate 802. 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. A rotating rod 804 is rotatably installed inside the screening box 1. The rotating rod 804 passes through the connecting block 803 and is slidably connected to the connecting block 803. Two vibration springs 805 are sleeved on the rotating rod 804. 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 far apart from each other are fixedly connected to the screening box 1.

[0048] Under the elastic force of the two vibrating springs 805, the connecting block 803 causes the medium filter plate 801 and the dust filter plate 802 to sway left and right. The swaying causes the larger unqualified alloy particles on the medium filter plate 801 to fall into the first chamber 509. The qualified alloy powder that falls from the medium filter plate 801 onto the dust filter plate 802 will enter the second chamber 510, and the remaining smaller alloy powder particles will enter the powder collection tray 505, thus completing the screening and collection of powders of different sizes.

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

[0050] The descent of the T-shaped block 608 will cause the isosceles trapezoidal plate 903 to descend, which in turn will cause the L-shaped contact block 904 to descend. The L-shaped contact block 904 will cause the medium filter plate 801 and the dust filter plate 802 to rotate a short distance around the rotating rod 804 and adjust their angle downwards.

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

[0052] When the second vibration spring 907 is stretched to its maximum extent, the L-shaped contact block 904 stops moving. At this time, the isosceles trapezoidal plate 903 slides into the mating groove 901. The mating spring 902 undergoes compression deformation. After the isosceles trapezoidal plate 903 leaves the L-shaped contact block 904, the second vibration spring 907 will drive the medium filter plate 801 and the dust filter plate 802 to recover under the action of elasticity 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 - Figure 10 As shown, a method for a vibratory screening device used in the production of cobalt-chromium-molybdenum alloy powder materials is described, and the method steps are as follows:

[0054] S1: Breaks up clumps and eliminates smoke and dust;

[0055] S2: Prevents powder from clogging;

[0056] S3: Up-and-down vibrating powder sieving;

[0057] S4: Left and right vibration sorting and sieving collection.

[0058] The alloy powder to be screened is placed into the feeding box 601. The powder enters the arc-shaped plate 501 inside the screening box 1 from the feeding box 601. The drive motor 2 is started, which drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the scraper 4 to rotate. The rotating scraper 4 scrapes up and throws the powder on the arc-shaped plate 501. When the scraper 4 leaves the arc-shaped plate 501, the powder will collide with the impact block 502 under the action of centrifugal force. The impact block 502 will break up the clumps in the powder. At this time, the powder will be dispersed and distributed in a medium-sized area due to centrifugal force and impact force. On the filter plate 801, no lumps of powder are present during the sieving process, thus improving the quality of the sieved powder. During the rotation of the rotating shaft 3, several fan blades 512 also rotate, generating suction force. This suction force, through the suction pipe 513, draws air into several micro-filter holes 506 on the side of the powder collection tray 505. Dust inside the sieving box 1 moves closer to the powder collection tray 505, drawing in the fumes and fine alloy powder particles generated during the sieving process. As the negative pressure increases, the suction pulls the U-shaped box 605 downwards. After the ventilation hole 606 on the U-shaped box 605 leaves the rectangular groove 603, the device is in a ventilated state, allowing for continuous collection of dust and powder into the powder collection tray 505. During the rotation of the scraper 4, it comes into contact with the conical rod 707. Because the elastic force of the transmission spring 706 is greater than that of the agitation spring 704, the conical rod 707 drives the agitation rod 701 to move closer to the collection box 508. At this time, the agitation spring 704 undergoes compression deformation. The stirring rod 701 stirs the powder in the feed box 601 to continuously enter the screening box 1, avoiding blockage and affecting the normal screening of the powder. When the stirring spring 704 is compressed to the maximum state, the conical 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 be compressed and deformed. When the scraper 4 leaves the conical rod 707, the conical rod 707 and the stirring rod 701 will be reset under the elastic force of the transmission spring 706 and the stirring spring 704 respectively, preparing for the next stirring.

[0059] During the rotation of scraper 4, it will contact T-block 608, causing T-block 608 to descend. At this time, the extension spring 609 will undergo tensile deformation. The descent of T-block 608 will drive the isosceles trapezoidal plate 903 to descend, which in turn will drive the L-shaped contact block 904 to descend. The L-shaped contact block 904 will then drive the medium filter plate 801 and the dust filter plate 802 to rotate a short distance around the rotating rod 804 and adjust their angle downwards. At this time, the vibration spring 907 will undergo tensile deformation. When the vibration spring 907 is stretched to its maximum extent, the L-shaped contact block 904 will no longer move. When the isosceles trapezoidal plate 903 slides into the mating groove 901, the mating spring 902 undergoes compression deformation. After the isosceles trapezoidal plate 903 leaves the L-shaped contact block 904, the vibration spring 907, under its elastic force, causes the medium filter plate 801 and dust filter plate 802 to recover and impact the triangular block 507, causing vibration and further dispersing the powder on the medium filter plate 801 and dust filter plate 802. 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 mating spring 902. 3 will come into contact with the irregular rod 905, and under the action of the inclined surface of the irregular rod 905, it will move the irregular rod 905 away from the isosceles trapezoidal plate 903. The irregular rod 905 will drive the medium filter plate 801 and the dust filter plate 802 to move simultaneously. At this time, the vibration spring 805 close to the irregular rod 905 will undergo compression deformation, and the vibration spring 805 away from the irregular rod 905 will undergo tensile deformation. When the scraper 4 of the isosceles trapezoidal plate 903 leaves the T-block 608, the T-block 608 will rise under the action of the telescopic spring 609, and the T-block 608 will drive... When the isosceles trapezoidal plate 903 moves away from the irregular rod 905, the connecting block 803 will cause the medium filter plate 801 and the dust filter plate 802 to sway left and right under the elastic force of the two vibration springs 805. The left and right swaying will cause the larger unqualified alloy particles on the medium filter plate 801 to fall into the first chamber 509. The qualified alloy powder that falls from the medium filter plate 801 onto the dust filter plate 802 will enter the second chamber 510. The remaining smaller alloy powder particles will enter the powder collection tray 505, thus completing the screening and collection of powders of different sizes.
