Description

Technical Field

[0001] This invention belongs to the field of metal powder processing technology, specifically a metal powder processing and grinding process. Background Technology

[0002] In the industrial production process of metal powder, ball mill grinding is the core link to realize the transformation of granular metal into powder. The typical processing path is as follows: first, the block metal is processed into granular raw materials of a preset size by crushing equipment, and then the granular metal is put into the inside of the ball mill. During the rotation of the ball mill, the grinding balls and metal particles are impacted, squeezed and rubbed to complete the grinding and refinement of the metal particles, and finally metal powder with the target particle size is obtained.

[0003] In existing technologies, ball mill drums are generally equipped with a baffle structure. Several arc-shaped grooves are evenly distributed on the baffle, allowing qualified metal powder with the required particle size to pass through the grooves into the discharge area of ​​the drum and then be discharged smoothly through the discharge port. However, coarse particles that do not meet the size requirements are blocked by the baffle in the grinding area and continue to be ground by the balls. During the grinding process, some coarse metal particles with a particle size close to but not fully meeting the size requirements of the arc-shaped grooves are easily embedded in them as the drum rotates. These embedded particles are difficult to detach on their own, and as the grinding time increases, the number of embedded particles accumulates, causing blockage inside the arc-shaped grooves. This significantly reduces the effective channels for qualified powder to pass through the baffle. When the arc-shaped grooves become blocked, the flow rate of qualified metal powder into the discharge area through the arc-shaped grooves decreases significantly, affecting the grinding efficiency of the metal powder. Therefore, we propose a metal powder processing and grinding technology. Summary of the Invention

Crushing block metal into granular raw materials of a preset size using crushing equipment; S2. The granular raw material is put into the ball mill for grinding. The grinding and refining of the metal particles is achieved by the impact, compression and friction between the grinding balls inside the drum and the metal particles during the rotation process. S3. The refined metal particles pass through the arc-shaped groove in the partition, and the unblocking mechanism clears the metal particles that are blocking the arc-shaped groove. S4. The refined metal particles are discharged outward through the discharge port.

[0006] Preferably, the ball mill in step S2 includes a base frame, a rotating drum rotatably mounted above the base frame, and two sets of sieve plates installed inside the rotating drum. The sieve plates have multiple sets of arc-shaped grooves inside, and the rotating drum has a clearing mechanism inside, the clearing mechanism including: A fixed plate is installed inside the rotating drum, and an mounting plate is provided on one side of the fixed plate. Multiple sets of scrapers are evenly distributed on the mounting plate along the length of the mounting plate to clear metal particles in the arc groove. Multiple sets of connecting rods are slidably arranged inside the fixed plate, and a movable plate is fixedly provided at one end of each connecting rod; An arc-shaped protrusion is provided on one side of the sieve plate.

[0007] Preferably, two sets of connecting springs are fixedly provided between the fixed plate and the movable plate, and an upper plate and a lower plate are fixedly provided at one end of the scraper block.

[0008] Preferably, the scraper block is slidably provided with an adjustment plate for adjusting according to the width of different arc grooves; The upper plate is internally connected to a screw rod via threads, and a rubber sleeve is fitted onto the top of the screw rod.

[0009] Preferably, a bracket is fixedly installed on the base frame, and the end of the fixing plate is fixed to the bracket.

[0010] Preferably, the end of the support is provided with a cleaning component, which includes a connecting frame fixed to the end of the support, a recessed frame slidably disposed on the connecting frame, and brush strips fixedly disposed at both ends of the recessed frame for sweeping away powder adhering to the surface of the sieve plate, the inside of the arc groove, and the surface of the scraper and the adjusting plate.

[0011] Preferably, a vibration motor is fixedly installed on the top of the brush bar, and a mounting spring is fixedly installed between the recess and the connecting frame.

[0012] Preferably, the cleaning component includes a pipe fixed to the end of the support, and an installation pipe is fixedly provided at the end of the pipe. Multiple sets of nozzles are evenly opened on the installation pipe along its length for blowing away and cooling the metal powder adhering to the surface of the sieve plate and accumulated inside the arc groove.

[0013] Preferably, the support has a hollow interior and a connector is fixedly installed on the top of the support.

[0014] Preferably, the base frame is provided with bearing seats at both ends, and the rotating drum is provided with an inlet and a discharge port at both ends.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention uses a designed unblocking mechanism to push the mounting plate to move through the arc-shaped convex plate, which drives the scraper to enter the arc-shaped groove, and cleans the coarse metal particles embedded and blocked in the arc-shaped groove in real time, so as to avoid the blockage of the arc-shaped groove and the obstruction of the discharge of qualified powder, and ensure the continuous smooth flow of the screening channel. The adjustment plate in the scraper can be adjusted by the screw to adapt to the width of the arc-shaped groove of different specifications, increasing the versatility of the equipment.

[0016] (2) The present invention uses a cleaning component consisting of a connecting frame, a brush bar, a vibrating motor, a recessed frame, and a mounting spring. The brush bar vibrates under the action of the vibrating motor, which can clean the metal powder attached to the scraper and the surface of the adjustment plate above the brush bar. This prevents the metal powder attached to the scraper and the surface of the adjustment plate from entering the arc groove with the scraper and falling into the arc groove, causing the powder to block the arc groove. At the same time, the vibrating motor can also shake off the metal powder attached to the brush bar itself and the mounting plate and other surrounding components on the unblocking mechanism through vibration, thereby improving the unblocking effect of the unblocking mechanism in the subsequent unblocking process.

[0017] (3) The present invention uses a cleaning component consisting of an installation pipe, a connector, a blower, and a pipe. The external ambient temperature airflow is blown onto the surface of the screen plate and the arc groove through the blower evenly distributed on the installation pipe. This can remove the metal powder remaining in the screen plate and the arc groove after the operation of the unblocking mechanism, avoid accumulation and blockage, and ensure the continuous smooth flow of the screening channel. In addition, the ambient temperature air blown out of the equipment (lower than the temperature inside the rotating drum) can reduce the heat generated by grinding friction inside the rotating drum, prevent the low melting point metal powder from softening and agglomerating, and ensure the uniformity of the metal powder particle size.

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0020] Example 1 Please see Figures 1-10 This invention provides a technical solution: a metal powder processing and grinding process, comprising the following steps: S1. Crushing block metal into granular raw materials of a preset size using crushing equipment; S2. The granular raw material is put into the ball mill for grinding. The grinding and refining of the metal particles is achieved by the impact, compression and friction of the grinding balls inside the rotating drum 102 during the rotation. S3. The refined metal particles pass through the arc-shaped groove 106 in the partition plate. The unblocking mechanism clears the metal particles that are blocked in the arc-shaped groove 106. The unblocking mechanism uses the movement of its own components to clean the metal particles blocked in the arc-shaped groove 106, ensuring that the arc-shaped groove 106 is unobstructed. This allows qualified refined metal particles to pass through the arc-shaped groove 106 smoothly, avoiding obstruction of qualified metal powder discharge due to blockage of the arc-shaped groove 106, which would affect the grinding efficiency. S4. The refined metal particles are discharged outward through the discharge port 104; The ball mill in step S2 includes a base frame 100, a rotating drum 102 rotatably mounted above the base frame 100, and two sets of sieve plates 105 installed inside the rotating drum 102. The rotating drum 102 rotates at a low speed, and when the rotating drum 102 rotates, it drives the internal sieve plates 105 to rotate synchronously. In the finely ground metal powder, particles with the required particle size can enter the subsequent discharge stage through the arc-shaped grooves 106, while coarse particles with the required particle size are blocked by the sieve plates 105 in the grinding area and continue to be ground. The sieve plates 105 have multiple sets of arc-shaped grooves 106 inside. The rotating drum 102 is equipped with a clearing mechanism, which includes: A fixed plate 203 is installed inside the rotating drum 102. A mounting plate 204 is provided on one side of the fixed plate 203. Multiple sets of scraper blocks 202 are evenly distributed on the mounting plate 204 along its length. The scraper blocks 202 are evenly distributed along the length of the mounting plate 204 and can correspond to multiple sets of arc grooves 106 on the screen plate 105, ensuring that each arc groove 106 can be cleared. During clearing, the scraper blocks 202 move towards the arc groove 106 and then penetrate into the interior of the arc groove 106 to scrape and clear the metal particles stuck and blocked inside the arc groove 106. Multiple sets of connecting rods 207 are slidably arranged inside the fixed plate 203. One end of the connecting rod 207 is fixedly provided with a movable plate 205, and the other end of the connecting rod 207 is fixedly connected to the scraper block 202. An arc-shaped protrusion 201 is provided on one side of the sieve plate 105. The arc-shaped protrusion 201 rotates with the rotation of the sieve plate 105. When the arc-shaped protrusion 201 rotates, one end of the arc-shaped groove 106 in the sieve plate 105 is aligned with the scraper block 202. At this time, the left protrusion of the arc-shaped protrusion 201 drives the mounting plate 204, the movable plate 205, the scraper block 202 and other structures to move closer to the arc-shaped groove 106 (the connecting spring 206 is compressed by the pressure of the movable plate 205). Subsequently, multiple sets of scraper blocks 202 enter the corresponding arc. The groove 106 clears the metal particles that are stuck and blocked. When the other end of the arc groove 106 in the screen plate 105 rotates to the point where it is almost out of alignment with the scraper 202, the protrusion in the arc convex plate 201 begins to decrease. Then, the mounting plate 204, scraper 202 and other structures move away from the arc groove 106. At this time, the scraper 202 disengages from the interior of the arc groove 106 and returns to its original position (the connecting spring 206 begins to reset). Multiple sets of L-shaped columns are fixedly arranged between the arc convex plate 201 and the screen plate 105.

[0021] Example 2 Please refer to Example 1. Figures 1-10Two sets of connecting springs 206 are fixedly installed between the fixed plate 203 and the movable plate 205. The connecting springs 206 facilitate the quick reset of the scraper block 202 to its original position after it is dislodged from the arc groove 106. One end of the scraper block 202 is fixed to the mounting plate 204. One end of the scraper block 202 is respectively fixed with an upper plate 209 and a lower plate 210. An adjusting plate 208 is slidably installed inside the scraper block 202 to adjust the width of the arc groove 106 according to different dimensions. When the width of the arc groove 106 on the screen plate 105 in different rotating drums 102 is different, the screw 213 is turned upward to loosen it, and then the adjusting plate 208 is moved away from the scraper block 202. At this time, the adjusting plate 208 moves from the inside to the outside of the scraper block 202. Then, when the adjusting plate 208 moves to the appropriate position, it stops moving. At this time, the width of the scraper block 202 and the width of the part extending to the outside of the scraper block 202 are added together to get the width of the arc groove 106. At this time, it can be adjusted according to the width of different arc grooves 106, increasing the versatility of the equipment. The upper plate 209 is internally connected to a screw 213 via threads, and the working end of the screw 213 extends to the surface of the adjusting plate 208. A rubber sleeve 212 is fitted on the top of the screw 213. The rubber sleeve 212 can cover the exposed part of the top of the screw 213 to prevent powder from adhering to the top of the screw 213 and causing wear during the subsequent rotation of the screw 213. A bracket 200 is fixedly installed on the base frame 100, and the end of the bracket 200 extends into the interior of the rotating drum 102. The end of the fixing plate 203 is fixed on the bracket 200. The bracket 200 is fixed to the base frame 100 by welding, bolt connection or other means. The bracket 200 provides a solid installation base for the fixing plate 203, so that the fixing plate 203 remains stationary during the rotation of the rotating drum 102 and the operation of the unblocking mechanism, and will not rotate with the rotating drum 102.

[0022] Example 3 Please refer to Example 2. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10The end of the support 200 is provided with a cleaning component, which includes a connecting frame 300 fixed to the end of the support 200. A recessed frame 303 is slidably disposed on the connecting frame 300. Brush strips 301 are fixedly disposed at both ends of the recessed frame 303. Multiple sets of bristles are provided on the top and sides of the brush strips 301. The bristles on the top contact the surfaces of the scraper 202 and the adjusting plate 208 above, sweeping the powder on the surfaces of the scraper 202 and the adjusting plate 208. The multiple sets of bristles on the sides contact the surface of the sieve plate 105 and the inside of the arc groove 106, sweeping the powder on the surface of the sieve plate 105 and the inside of the arc groove 106. This is used to remove the powder adhering to the surface of the sieve plate 105, the inside of the arc groove 106, and the surfaces of the scraper 202 and the adjusting plate 208. The brush strips 301 can... The scraper 202 removes some remaining powder accumulated inside the arc-shaped groove 106 and on the surface of the sieve plate 105 after being scraped by the scraper, further increasing the cleaning effect inside the arc-shaped groove 106. In conjunction with the vibration motor 302, it vibrates and shakes off some powder adhering to the surface of the brush strip 301, scraper 202 and adjusting plate 208. At the same time, the vibration force of the vibration motor 302 is also transmitted to some surrounding components connected to it, causing some powder adhering to the support 200, mounting plate 204 and other structures to fall off due to vibration. Cleaning these components can remove metal powder adhering to the scraper 202 and adjusting plate 208, as well as powder adhering to the brush strip 301 and other components connected to it. A vibration motor 302 is fixedly installed on the top of the brush strip 301, and a mounting spring 304 is fixedly installed between the recessed frame 303 and the connecting frame 300. The mounting spring 304 can squeeze the brush strip 301 towards the screen plate 105, so that the brush strip 301 can make closer contact with the screen plate 105 and the interior of the arc groove 106, thereby increasing the cleaning effect.

[0023] In this embodiment, bearing seats are provided at both ends of the base frame 100, and inlet 101 and discharge port 104 are provided at both ends of the rotating drum 102. The ends of inlet 101 and discharge port 104 pass through the interior of the bearing seats. Inspection cover 103 is provided on the rotating drum 102. By opening the inspection cover 103, the interior of the rotating drum 102 can be inspected. When adjusting according to the width of the arc groove 106, the position of the adjusting plate 208 can be adjusted by rotating the screw 213 after opening the inspection cover 103, or the position of the adjusting plate 208 can be adjusted by rotating the screw 213 outside the equipment before the screen plate 105 is installed inside the rotating drum 102.

[0024] Example 4 Please refer to Example 3. Figure 11 and Figure 12The cleaning component includes a pipe fixed to the end of the bracket 200. An installation pipe 400 is fixedly installed at the end of the pipe. Multiple sets of nozzles 402 are evenly distributed along the length of the installation pipe 400 to blow away and cool the metal powder accumulated on the surface of the sieve plate 105 and inside the arc groove 106. A connector 401 connects to an external blower, which generates strong air, which is delivered to the nozzles 402. Strong air is blown through the nozzles 402 into the sieve plate 105 and the arc groove 106, removing the powder accumulated on the surface of the sieve plate 105 and inside the arc groove 106. Simultaneously, the nozzles 402 blow out ambient temperature air from outside the equipment. When the rotating drum 102 rotates, the grinding balls (such as steel balls) located inside the rotating drum 102... The grinding ball and the metal particles, as well as the grinding ball and the inner wall of the rotating drum 102, will continuously rub against each other. During the friction process, mechanical energy will be converted into heat energy, causing the inside of the rotating drum 102 to heat up. At this time, the temperature inside the rotating drum 102 will increase. The air blown out through the nozzle 402 is at room temperature, which is lower than the temperature inside the rotating drum 102. This will cool down the sieve plate 105, the powder, and the inner wall of the rotating drum 102, preventing the internal temperature from being too high and changing the physical properties of the metal powder. For example, it may cause local softening or agglomeration of low melting point metals (such as aluminum and zinc), affecting the uniformity of powder particle size. This can clean the powder accumulated on the surface of the sieve plate 105 and inside the arc groove 106, and at the same time cool down the inside of the rotating drum 102, reducing the adverse effects caused by the temperature increase. The bracket 200 has a hollow interior and a connector 401 is fixedly installed on the top of the bracket 200. The connector 401, the bracket 200, the pipe and the installation pipe 400 are connected.

[0025] Working principle and usage process of this invention: In use, the rotating drum 102 rotates, causing the two sets of screen plates 105 inside to rotate synchronously. During the rotation of the screen plates 105, the arc-shaped protrusion 201 on one side rotates synchronously. When the protruding part of the arc-shaped protrusion 201 contacts the mounting plate 204 (the rear end of the arc-shaped groove 106 located on the screen plate 105 near the back is aligned with the mounting plate 204), it pushes the mounting plate 204 to move closer to the arc-shaped groove 106. The mounting plate 204 drives the scraper 202, connecting rod 207, and movable plate 205 to move synchronously. At this time, the connecting spring 206 is compressed by the movable plate 205. Subsequently, scraper 202 enters the arc-shaped groove 106 to scrape and clear the unqualified coarse particles stuck in the arc-shaped groove 106. Then, as the screen plate 105 continues to rotate, scraper 202 continues to clear the metal particles blocking the middle area of ​​the arc-shaped groove 106. When the left protruding part of the arc-shaped convex plate 201 disengages from the movable plate 205 (one end of the arc-shaped groove 106 located on the front of the screen plate 105 no longer aligns with the mounting plate 204), the connecting spring 206 between the fixed plate 203 and the movable plate 205 releases its elastic potential energy, causing the movable plate 205 to move away from the screen plate 105. The direction of movement resets, thereby moving the scraper 202, mounting plate 204, connecting rod 207, and movable plate 205. At this time, the scraper 202 disengages from the arc groove 106 and returns to its initial position, completing one unblocking cycle and ensuring the arc groove 106 is unobstructed. Simultaneously, the brush strip 301 in the end cleaning component of the bracket 200 contacts the surfaces of the scraper 202 and adjusting plate 208. The brush strip 301 cooperates with the vibration motor 302 to vibrate the scraper 202, adjusting plate 208, and surrounding components, shaking off the metal powder on their surfaces. The vibration also shakes off the metal powder adhering to the surface of the brush strip 301 itself. In conjunction with the vibration motor 302, 301 can also remove the metal powder accumulated on the surface of the sieve plate 105 and inside the arc groove 106 (after being scraped off by the scraper 202). The removed metal powder enters the discharge area (located in the right side area of ​​the sieve plate 105) along with the qualified powder. The mounting spring 304 between the recessed frame 303 and the connecting frame 300 ensures that the brush strip 301 is always in contact with the surface of the sieve plate 105 (the mounting spring 304 in a compressed state generates a restoring force outward), thereby driving the recessed frame 303 to move closer to the sieve plate 105, so that the brush strip 301 is in close contact with the surface of the sieve plate 105, improving the cleaning effect. When clearing the arc groove 106 of different widths, the rubber cylinder 212 is removed, and the screw 213 is turned upwards to loosen it, thus releasing the fixing of the adjusting plate 208. Then, the adjusting plate 208 is moved to the back of the equipment to a suitable position, and then the screw 213 is turned downwards to tighten it, thus fixing the adjusting plate 208. When clearing the metal particles blocking the arc groove 106, the adjusting plate 208 and the part of the adjusting plate 208 extending to the outside of the scraper 202 together form a width consistent with the arc groove 106 of different widths. At this time, the adjusting plate 208 and the scraper 202 work together to clear the metal particles blocking the arc groove 106. After the unblocking mechanism unblocks the blockage, it blows air through multiple nozzles 402 on the installation pipe 400 to the metal powder inside the rotating drum 102, the sieve plate 105 and other surfaces, with a temperature lower than that inside the rotating drum 102. This not only blows away the metal powder accumulated on the surface of the sieve plate 105 and in the arc groove 106, but also cools down the temperature inside the rotating drum 102.

[0026] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
