Description

Technical Field

[0001] The present invention belongs to the technical field of metal powder production, and specifically relates to an automatic powder grinding device for metal powder production. Background Art

[0002] Metal powder is an aggregate of tiny particles made from metals or alloys by physical, chemical, or mechanical methods. Its particle size is usually in the range of micrometers to nanometers, and it has specific shapes, particle size distributions, and physical and chemical properties. It is widely used in high-tech industries such as 3D printing, powder metallurgy, coating preparation, and electronic devices.

[0003] The production of metal powder mainly includes atomization method, mechanical crushing method, reduction method, electrolysis method, etc. In mechanical grinding, usually, grinding media (steel balls, ceramic balls) in a ball mill are thrown when the drum rotates, generating an impact force (the instantaneous pressure can reach 5 - 10 GPa) on metal particles to directly break the metal material to prepare metal powder. However, the metal block and the grinding media are located in the grinding cavity. As the cavity continuously rotates, the media continuously impacts the metal block, gradually forming metal powder. As the metal is gradually broken, some of the fine particles that have reached the standard will be further broken due to continuous retention, resulting in a deterioration of the particle size distribution and an obvious bimodal distribution phenomenon, seriously affecting the fluidity and powder spreading uniformity of the powder. At the same time, the retention effect will increase the oxidation risk of the powder and affect the quality of the metal powder. Therefore, an automatic powder grinding device for metal powder production is proposed. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides an automatic powder grinding device for metal powder production, which solves the problem that the fine particles that have reached the standard are further broken due to continuous retention during the process of preparing metal powder by the existing ball mill, affecting the quality of the metal powder.

[0005] To achieve the above object, the present invention provides the following technical solution: An automatic powder grinding device for metal powder production, including a base, and further including:

[0006] A protection component, which is fixedly installed on the top of the base;

[0007] A grinding component, which is movably arranged inside the protection component;

[0008] A cleaning component, which is fixedly installed inside the protection component, and air is injected into the cleaning component through an air injection pump;

[0009] Among them, the protection component includes a protection cavity fixedly installed on the top of the base;

[0010] The grinding assembly includes a grinding cavity movably sleeved inside the protective cavity. Rectangular through slots are annularly and arrayedly formed on the outer part of the grinding cavity, and alloy screens are installed in the rectangular through slots. The alloy screens are installed on the grinding cavity through docking members;

[0011] An overhaul and replacement opening for replacing alloy screens with different mesh numbers is formed on the outer part of the protective cavity;

[0012] Metal blocks and grinding media are injected into the grinding cavity. The metal blocks are impacted by the media to form metal powder. Qualified metal particles enter the protective cavity through the alloy screens and are discharged and collected through the discharge ports.

[0013] Preferably, the grinding assembly further includes a first transmission wheel and a second transmission rod installed outside the grinding cavity through a docking support frame. The first transmission wheel and the second transmission rod are located at both ends of the alloy screen;

[0014] A transmission member is externally connected to the first transmission wheel and the second transmission rod. The transmission member is located outside the alloy screen.

[0015] Preferably, both ends of the transmission member are in contact with the outer part of the docking support frame. The docking support frame supports the transmission member to make the arc of the transmission member consistent with that of the alloy screen.

[0016] Preferably, support members are annularly and arrayedly arranged on the outer part of the transmission member. The support members are in contact with the outer part of the alloy screen. A notch for storing metal powder is formed between two adjacent support members.

[0017] Preferably, an arc-shaped rack is fixedly installed on the inner wall of the cleaning assembly. The arc-shaped rack is located at the right side of the bottom of the grinding cavity;

[0018] Driving gears are fixedly installed at both ends of the first transmission wheel. The driving gears rotate with the grinding cavity to the arc-shaped rack and engage with it, and drive the transmission member and the support members to rotate along the arc-shaped rack.

[0019] Preferably, the cleaning assembly includes a fixed diversion cavity fixedly installed on the inner wall of the protective cavity. The arc-shaped rack is fixedly installed on the inner wall of the fixed diversion cavity;

[0020] One end of the fixed diversion cavity is open. A driving circular plate is sleeved at the opening of the fixed diversion cavity to make the fixed diversion cavity form a sealed cavity. A limiting member for limiting the driving circular plate is arranged inside the fixed diversion cavity. The driving circular plate is fixedly connected to the grinding cavity through a docking member.

[0021] Preferably, an exhaust cavity is fixedly installed between the two docking support frames. A communication pipe is connected to the outside of the exhaust cavity. One end of the communication pipe is connected to the transmission circular plate, so that the exhaust cavity is communicated with the fixed shunt cavity;

[0022] The gas injection end of the gas injection pump is communicated with the inside of the fixed shunt cavity.

[0023] Preferably, the outside of the exhaust cavity is in contact with the inner wall of the transmission member. The middle of the transmission member is made of a woven fabric material. Exhaust holes are distributed on the inner arc surface of the exhaust cavity.

[0024] Preferably, an arc-shaped plugging member is fixedly installed inside the fixed shunt cavity. The arc-shaped plugging member is used to plug the communication pipe. Both the arc-shaped plugging member and the arc-shaped rack are located at the right side of the bottom of the grinding cavity.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the present invention, the metal block is gradually made into a powder form by the continuous impact of the medium. As the grinding cavity continues to rotate, the alloy screen is successively located at the bottom of the grinding cavity. At this time, the qualified metal powder enters the inside of the protective cavity through the alloy screen. Since the grinding cavity and the alloy screen continue to rotate, the grinding medium and the metal block inside are turned over. The qualified metal powder has a smaller particle size and fits more closely to the inner walls of the grinding cavity and the alloy screen. In this process, the phenomenon of material accumulation is avoided, and at the same time, it is ensured that the qualified metal powder can pass through the alloy screen normally and is discharged through the discharge port for collection, avoiding the retention of the qualified metal powder in the grinding box;

[0027] In the present invention, the support member is in contact with the outside of the alloy screen. During the rotation of the grinding cavity and the alloy screen, the grinding medium and the metal block roll inside. The grinding medium and the metal block impact each other, and at the same time, they will impact the alloy screen. Thus, the alloy screen is supported by the support member, improving the strength of the alloy screen and avoiding the deformation of the alloy screen caused by the impact of the grinding medium and the metal block;

[0028] In the present invention, the grinding cavity drives the transmission gear, the first transmission wheel and the transmission member to rotate. The transmission gear rotates to the bottom of the grinding cavity and meshes with the arc-shaped rack, so that the transmission gear drives the first transmission wheel and the transmission member to rotate under the action of the arc-shaped rack. During the rotation of the transmission member, since the support member contacts the alloy screen, the stability of the alloy screen is improved. At the same time, the qualified metal powder in the grinding cavity falls into the notch between two adjacent support members on the inner circle of the transmission member through the alloy screen, and is transported to the inside of the protection cavity through the rotation of the transmission member. Since the transmission member is arc-shaped, the metal powder falls between two adjacent support members on the inner arc surface of the transmission member. As the transmission member continues to rotate, the support member located on the inner arc surface rotates to the outer arc surface. During this process, the distance between two adjacent support members on the outer arc surface is greater than the distance between two adjacent support members on the inner arc surface, so that it is convenient for the metal powder to break away from the transmission member.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] As Figures 1 to 11 shown, the present invention provides an automatic powder grinding device for metal powder production, including a base 1, and further including:

[0043] A protection component 2, which is fixedly installed on the top of the base 1;

[0044] A grinding component 5, which is movably arranged inside the protection component 2;

[0045] A cleaning component 6, which is fixedly installed inside the protection component 2, and air is injected into the inside of the cleaning component 6 through an air injection pump 4;

[0046] Among them, the protection component 2 includes a protection cavity 21 fixedly installed on the top of the base 1;

[0047] The grinding component 5 includes a grinding cavity 51 movably sleeved inside the protection cavity 21. Rectangular through grooves are annularly arranged on the outside of the grinding cavity 51, and alloy screens 52 are installed in the rectangular through grooves. The alloy screens 52 are installed on the grinding cavity 51 through docking members;

[0048] An overhaul and replacement port 23 for replacing different meshes of the alloy screen 52 is arranged on the outside of the protection cavity 21;

[0049] Metal blocks and grinding media are injected into the grinding cavity 51, and the metal blocks are impacted by the media to form metal powder. The qualified metal particles pass through the alloy screen 52 and enter the protection cavity 21 and are discharged and collected through the discharge port 22.

[0050] According to the particle size of the metal powder particles, an alloy sieve mesh 52 with an appropriate mesh number is selected. The metal block and the grinding medium are injected into the grinding cavity 51. The grinding cavity 51 is driven to rotate by a motor. The metal block is gradually made into a powder form by the continuous impact of the medium. As the grinding cavity 51 continues to rotate, the alloy sieve mesh 52 is successively located at the bottom of the grinding cavity 51. At this time, the qualified metal powder enters the interior of the protective cavity 21 through the alloy sieve mesh 52. Since the grinding cavity 51 and the alloy sieve mesh 52 continue to rotate, the grinding medium and the metal block inside are turned over. The qualified metal powder with a smaller particle size fits more closely to the inner walls of the grinding cavity 51 and the alloy sieve mesh 52. During this process, the phenomenon of material accumulation is avoided, and at the same time, it is ensured that the qualified metal powder can pass through the alloy sieve mesh 52 normally and is discharged through the discharge port 22 for collection, preventing the qualified metal powder from staying in the grinding box.

[0051] The specific working principle of the ball mill will not be elaborated here.

[0052] As Figures 3 - 6 shown, the grinding assembly 5 further includes a first transmission wheel 53 and a second transmission rod 58 installed outside the grinding cavity 51 through a docking support frame 55. The first transmission wheel 53 and the second transmission rod 58 are located at both ends of the alloy sieve mesh 52;

[0053] The outside of the first transmission wheel 53 and the second transmission rod 58 is externally connected with a transmission member 57, and the transmission member 57 is located outside the alloy sieve mesh 52;

[0054] Both ends of the transmission member 57 are in contact with the outside of the docking support frame 55. The transmission member 57 is supported by the docking support frame 55 to make the arc of the transmission member 57 consistent with that of the alloy sieve mesh 52;

[0055] The outside of the transmission member 57 is provided with support members 56 arranged in an annular array. The support members 56 are in contact with the outside of the alloy sieve mesh 52, and a storage metal powder notch is formed between two adjacent support members 56.

[0056] By the contact between the support members 56 and the outside of the alloy sieve mesh 52, during the rotation of the grinding cavity 51 and the alloy sieve mesh 52, the grinding medium and the metal block roll inside, and the grinding medium and the metal block impact each other. At the same time, they will impact the alloy sieve mesh 52. Thus, the alloy sieve mesh 52 is supported by the support members 56, improving the strength of the alloy sieve mesh 52 and preventing the deformation of the alloy sieve mesh 52 caused by the impact of the grinding medium and the metal block.

[0057] As Figure 10 With Figure 11 shown, an arc-shaped rack 59 is fixedly installed on the inner wall of the cleaning assembly 6. The arc-shaped rack 59 is located at the right side of the bottom of the grinding cavity 51;

[0058] Both ends of the first driving wheel 53 are fixedly equipped with driving gears 54. The driving gears 54 rotate with the grinding cavity 51 and engage with the arc-shaped rack 59 at the arc-shaped rack 59, and drive the transmission member 57 and the support member 56 to rotate along the arc-shaped rack 59.

[0059] The grinding cavity 51 drives the driving gear 54, the first driving wheel 53 and the transmission member 57 to rotate. The driving gear 54 rotates to the bottom of the grinding cavity 51 and engages with the arc-shaped rack 59, so that the driving gear 54 drives the first driving wheel 53 and the transmission member 57 to rotate under the action of the arc-shaped rack 59. During the rotation of the transmission member 57, since the support member 56 contacts the alloy screen 52, the stability of the alloy screen 52 is improved. At the same time, the qualified metal powder in the grinding cavity 51 falls into the notch between two adjacent support members 56 on the inner circle of the transmission member 57 through the alloy screen 52. As the transmission member 57 continues to rotate, the qualified metal powder in the notch is transported to the inside of the protection cavity 21 through the rotation of the transmission member 57;

[0060] At the same time, since the transmission member 57 is arc-shaped, the metal powder falls between two adjacent support members 56 on the inner arc surface of the transmission member 57. As the transmission member 57 continues to rotate, the support member 56 located on the inner arc surface rotates to the outer arc surface. During this process, the distance between two adjacent support members 56 on the outer arc surface is greater than the distance between two adjacent support members 56 on the inner arc surface, so that it is convenient for the metal powder to break away from the transmission member 57.

[0061] As Figures 9 - 11 shown, the cleaning assembly 6 includes a fixed diversion cavity 61 fixedly installed on the inner wall of the protection cavity 21, and the arc-shaped rack 59 is fixedly installed on the inner wall of the fixed diversion cavity 61;

[0062] One end of the fixed diversion cavity 61 is open. The fixed diversion cavity 61 is sleeved at the opening of the fixed diversion cavity 61 through a transmission circular plate 63, so that the fixed diversion cavity 61 forms a sealed cavity. A limiting member 62 for limiting the transmission circular plate 63 is arranged inside the fixed diversion cavity 61, and the transmission circular plate 63 is fixedly connected to the grinding cavity 51 through a docking member 64;

[0063] An exhaust cavity 511 is fixedly installed between the two docking support frames 55. A communication pipe 512 is connected to the outside of the exhaust cavity 511. One end of the communication pipe 512 is connected to the transmission circular plate 63, so that the exhaust cavity 511 is communicated with the inside of the fixed diversion cavity 61;

[0064] The gas injection end of the gas injection pump 4 is communicated with the inside of the fixed diversion cavity 61;

[0065] The outside of the exhaust cavity 511 is in contact with the inner wall of the transmission member 57. The middle part of the transmission member 57 is made of a woven fabric material. Exhaust holes are distributed on the inner arc surface of the exhaust cavity 511;

[0066] Inside the fixed flow - dividing cavity 61, an arc - shaped plugging member 65 is fixedly installed. The arc - shaped plugging member 65 is used to plug the connecting pipe 512. Both the arc - shaped plugging member 65 and the arc - shaped rack 59 are located at the right - hand side near the bottom of the grinding cavity 51.

[0067] The air injection pump 4 continuously injects air into the fixed flow - dividing cavity 61. When the grinding cavity 51 rotates to drive the transmission gear 54 to mesh with the arc - shaped rack 59 and drives the transmission member 57 to rotate, the arc - shaped plugging member 65 plugs the air inlet of the exhaust cavity 511 inside the rotating transmission member 57. At this time, gas cannot enter the inside of the exhaust cavity 511. At this time, the qualified metal powder in the grinding cavity 51 falls into the notch between two adjacent support members 56. At the same time, as the grinding cavity 51 continues to rotate, the transmission gear 54 disengages from the arc - shaped rack 59. At this time, the transmission member 57 rotates to the upper end of the grinding cavity 51, and at the same time, the exhaust cavity 511 communicates with the fixed flow - dividing cavity 61. Gas enters the exhaust cavity 511 and is discharged through the air holes distributed on the inner arc surface. The gas passes through the transmission member 57 to clean the alloy screen 52. Since the support members 56 are in contact with the outside of the alloy screen 52, the gas is guided by two adjacent support members 56, so that the gas can only pass through the alloy screen 52, realizing back - blowing of the alloy screen 52 to avoid the phenomenon of blockage of the alloy screen 52.

[0068] The working principle and usage process of the present invention:

[0069] According to the particle size of the metal powder particles, an alloy screen 52 with a suitable mesh number is selected. The metal block and the grinding medium are injected into the grinding cavity 51. The grinding cavity 51 is driven to rotate by the motor. The metal block is gradually made into powder form by the continuous impact of the medium. As the grinding cavity 51 continues to rotate, the alloy screen 52 is successively located at the bottom of the grinding cavity 51. At this time, the qualified metal powder enters the inside of the protection cavity 21 through the alloy screen 52. Since the grinding cavity 51 and the alloy screen 52 continue to rotate, the grinding medium and the metal block inside are turned over. The qualified metal powder with a smaller particle size fits more closely to the inner walls of the grinding cavity 51 and the alloy screen 52. During this process, the phenomenon of material accumulation is avoided, and at the same time, it is ensured that the qualified metal powder can pass through the alloy screen 52 normally and is discharged through the discharge port 22 for collection, avoiding the retention of qualified metal powder in the grinding box.

[0070] Due to the external contact between the support members 56 and the alloy screen 52, during the rotation of the grinding cavity 51 and the alloy screen 52, the grinding medium and the metal block roll inside, and the grinding medium and the metal block impact each other and will also impact the alloy screen 52. Thus, the support members 56 support the alloy screen 52, improving the strength of the alloy screen 52 and avoiding the deformation of the alloy screen 52 caused by the impact of the grinding medium and the metal block.

[0071] The grinding cavity 51 drives the transmission gear 54, the first transmission wheel 53 and the transmission member 57 to rotate. The transmission gear 54 rotates to the bottom of the grinding cavity 51 and meshes with the arc-shaped rack 59, so that the transmission gear 54 drives the first transmission wheel 53 and the transmission member 57 to rotate under the action of the arc-shaped rack 59. During the rotation of the transmission member 57, since the support member 56 contacts the alloy screen 52, the stability of the alloy screen 52 is improved. At the same time, the qualified metal powder in the grinding cavity 51 falls into the notch between two adjacent support members 56 on the inner circle of the transmission member 57 through the alloy screen 52. As the transmission member 57 continues to rotate, the qualified metal powder in the notch is transported to the inside of the protection cavity 21 by the rotation of the transmission member 57;

[0072] At the same time, since the transmission member 57 is arc-shaped, the metal powder falls between two adjacent support members 56 on the inner arc surface of the transmission member 57. As the transmission member 57 continues to rotate, the support member 56 located on the inner arc surface rotates to the outer arc surface. During this process, the distance between two adjacent support members 56 on the outer arc surface is greater than the distance between two adjacent support members 56 on the inner arc surface, so as to facilitate the metal powder to break away from the transmission member 57;

[0073] The air injection pump 4 continuously injects air into the fixed flow distribution cavity 61. When the grinding cavity 51 rotates and the transmission gear 54 meshes with the arc-shaped rack 59 to drive the transmission member 57 to rotate, the arc-shaped sealing member 65 seals the air inlet of the exhaust cavity 511 in the rotating transmission member 57. At this time, the gas cannot enter the inside of the exhaust cavity 511. At this time, the qualified metal powder in the grinding cavity 51 falls into the notch between two adjacent support members 56. At the same time, as the grinding cavity 51 continues to rotate, the transmission gear 54 disengages from the arc-shaped rack 59. At this time, the transmission member 57 rotates to the upper end of the grinding cavity 51. At the same time, the exhaust cavity 511 is communicated with the fixed flow distribution cavity 61, and the gas enters the exhaust cavity 511 and is discharged through the air holes distributed on the inner arc surface. The gas passes through the transmission member 57 to clean the alloy screen 52. Since the support member 56 contacts the outside of the alloy screen 52, the gas is guided by two adjacent support members 56, so that the gas can only pass through the alloy screen 52 to perform back blowing on the alloy screen 52 to avoid the phenomenon of blockage of the alloy screen 52.
