Technical Field

[0001] The utility model relates to the technical field of metal micropowder collection, in particular to a metal micropowder collection and filtering device. Background Art

[0002] The metal powder collection and filtration device is a device used to collect and filter metal powders. During the metal processing and manufacturing process, a large amount of metal powders are often generated. If these powders are scattered or discharged at will, they will cause harm to the environment and human health. Therefore, the metal powder collection and filtration device can effectively collect and filter these powders, thereby reducing pollution to the environment and harm to human health.

[0003] Patent number "CN110860940A" discloses a "metal powder collection device for screw production". This device is convenient because it uses a wide-mouthed, beveled hopper, and the largest area of metal powder falling from the top of the processing machine tool is collected. The outlet end of the hopper is facing the receiving box. The metal powder located on the inclined wall of the hopper can be quickly discharged through a vibration motor, and the discharge efficiency is high. There is only a distance of 5 cm between the two, which further makes the discharge more accurate. At the same time, four universal wheels are provided, and the specific work station of the collection device can be adjusted according to the specific discharge position. Due to the difference in the utilization rate of metal powder of different particle sizes, the above-mentioned device only achieves the effect of centralized collection of metal powder, and does not achieve the effect of graded storage, and the overall collection effect is poor. Utility Model Content

However, the existing device only achieves the effect of centralized collection of metal powders, but does not achieve the effect of graded storage.

[0005] The filter screen is installed on the top of the filter box, and the filter screen is installed on the top of the filter box.

[0006] Preferably, the isolation and collection mechanism includes a limiting scraper and a feed trough, the limiting mounting plate is located on the side outer wall of the protective filter and is fitted with a limiting scraper, the side outer wall of the limiting scraper is provided with a support shaft, and the support shaft is connected to the rotating shaft of the limiting fan, and the bottom inner wall of the limiting box at the position of the limiting scraper is provided with a feed trough.

[0007] Preferably, the filtering and screening mechanism includes a limiting screen plate, a limiting T-shaped block and a limiting T-shaped slot. A limiting screen plate is arranged inside the filter box, two groups of limiting T-shaped blocks are symmetrically arranged on the outer walls on both sides of the limiting screen plate, and two groups of limiting T-shaped slots are symmetrically opened on the side inner walls of the filter box.

[0008] Preferably, the limiting T-shaped block and the limiting T-shaped slot are slidably mounted, and a return spring is connected between the top outer wall of the limiting T-shaped block and the top inner wall of the limiting T-shaped slot.

[0009] Preferably, the top outer wall and the bottom outer wall of the limiting screen plate are both provided with protective plates, and the side outer walls of the protective plates are in contact with the side inner walls of the filter box.

[0010] Preferably, an auxiliary support plate is provided on the side outer wall of the filter box, the auxiliary support plate is arranged in an "L" shape, and a control motor is provided on the side inner wall of the auxiliary support plate.

[0011] Preferably, the control motor is connected to one end of the transmission shaft, and the other end of the transmission shaft passes through the outer wall of one side of the filter box and is rotatably installed on the inner wall of the other side of the filter box. The outside of the transmission shaft located inside the filter box is symmetrically arranged on a limit cam, and the limit cam is located directly below the limit screen plate.

[0012] Preferably, the limiting sieve plate is configured as a porous sieve plate structure, and the height of the protective plate is greater than the groove height of the limiting T-shaped groove.

When the metal powder collecting and filtering device is in use, the limiting screen plate, limiting T-shaped block, limiting T-shaped slot, return spring, protective plate, auxiliary support plate, control motor, transmission shaft and limiting cam are set, and the limiting screen plate is set as a porous filter structure. The rotation of the cam and the interference between the limiting screen plate enable the device to automatically filter the concentrated metal powder collected, so that the metal particles with larger particle sizes will accumulate above the limiting screen plate, and the metal particles with smaller particle sizes will automatically fall to the bottom of the filter box, so that the two can be distinguished and recycled through different treatment methods, without the need for subsequent additional screening process, thereby improving the overall utilization rate of the metal powder and having a good overall practical effect;

[0015] 2. When the metal powder collecting and filtering device is in use, the limiting fan in the suction and collection mechanism is linked to drive the limiting scraper in the isolation and collection mechanism to rotate, so that the limiting scraper will automatically scrape and collect the metal powder accumulated on the outer wall of the protective filter under negative pressure when rotating. On the basis of ensuring the cleanliness of the outer wall of the protective filter, the normal powder absorption effect of the device is guaranteed, and the overall practical effect is good.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-6 As shown, a metal powder collecting and filtering device comprises a supporting base 1 and a filter box 2: a filter box 2 is provided on the top outer wall of the supporting base 1, a suction and collecting mechanism 3 is provided inside the filter box 2, an isolation and collecting mechanism 4 is provided on the side of the suction and collecting mechanism 3, and a filtering and screening mechanism 5 is provided below the isolation and collecting mechanism 4, the suction and collecting mechanism 3 comprises a limit box 31, a driving motor 32, a driving shaft 33, a limit fan 34, a limit mounting plate 35 and a limit guide tube 36, a limit box 31 is provided on the side inner wall of the filter box 2 at the top position, a driving motor 32 is provided on the side inner wall of the limit box 31, the driving motor 32 is connected to one end of the driving shaft 33, and the other end of the driving shaft 33 is connected to the limit fan 34, a limit mounting plate 35 is provided on the side of the limit fan 34, and a placement groove is provided through the side outer wall of the limit mounting plate 35 at the position of the limit fan 34, and the placement groove is provided with a A protective filter is provided, and a limiting duct 36 is installed on the side outer wall of the limit box 31. The protruding end of the limiting duct 36 is arranged on the outside of the filter box 2, and a flange is provided on the outside of the limiting duct 36; when it is necessary to collect the residual silver powder processed on the processing table into the interior of the device, it is first necessary to install a docking hose on the limiting duct 36 through the flange, align the hose with the position of the silver powder to be collected, and then turn on the drive motor 32. When the drive motor 32 is turned on, it will automatically drive the drive shaft 33 to rotate and then drive the limiting fan 34 to rotate. It is noted here that the limiting fan 34 is set to be installed in reverse. When it rotates, it will draw the silver powder on the workbench into the inside of the hose through negative pressure extraction and then transport it to the inside of the device. Here, due to the installation of a protective filter inside the limit mounting plate 35, when the airflow carrying silver powder passes through the protective filter, the silver powder will be automatically isolated outside the protective filter.

[0025] The isolation and collection mechanism 4 includes a limiting scraper 41 and a feed trough 42. The limiting mounting plate 35 is located on the side outer wall of the protective filter and is fitted with the limiting scraper 41. The side outer wall of the limiting scraper 41 is provided with a support shaft, and the support shaft is connected to the rotating shaft of the limiting fan 34. The bottom inner wall of the limit box 31 at the position of the limiting scraper 41 is provided with a feed trough 42; when the above-mentioned limiting fan 34 rotates, it will also synchronously drive the support shaft to rotate and then drive the limiting scraper 41 to rotate. When the limiting scraper 41 rotates, it will automatically push the silver powder adhered to the negative pressure on the outside of the protective filter through the feed trough 42 through the inertial push to the top of the limiting screen plate 51, thereby achieving the effect of centralized collection.

[0026] The filtering and screening mechanism 5 includes a limiting screen plate 51, a limiting T-shaped block 52 and a limiting T-shaped slot 53. The limiting screen plate 51 is arranged inside the filter box 2. Two groups of limiting T-shaped blocks 52 are symmetrically arranged on the outer walls of both sides of the limiting screen plate 51. Two groups of limiting T-shaped slots 53 are symmetrically opened on the side inner walls of the filter box 2. The limiting T-shaped blocks 52 and the limiting T-shaped slots 53 are symmetrically installed. A reset spring 54 is connected between the top outer wall of the limiting T-shaped block 52 and the top inner wall of the limiting T-shaped slot 53. The top outer wall and the bottom outer wall of the limiting screen plate 51 are both provided with There is a protective plate 55, and the side outer wall of the protective plate 55 fits with the side inner wall of the filter box 2. The side outer wall of the filter box 2 is provided with an auxiliary support plate 56, and the auxiliary support plate 56 is set in an "L" shape. The side inner wall of the auxiliary support plate 56 is provided with a control motor 57. The control motor 57 is connected to one end of the transmission shaft 58. The other end of the transmission shaft 58 passes through the outer wall of one side of the filter box 2 and is rotatably installed on the inner wall of the other side of the filter box 2. The outside of the transmission shaft 58 located inside the filter box 2 is symmetrically provided with a limit cam 59. The limit The cam 59 is located just below the limiting sieve plate 51. When it is necessary to separate the silver powder accumulated above the limiting sieve plate 51 into large and small particles, the control motor 57 needs to be turned on first. The setting of the auxiliary support plate 56 here plays an auxiliary supporting role for the control motor 57. When the control motor 57 is turned on, it will automatically drive the transmission shaft 58 to rotate and then drive the limiting cam 59 to rotate. When the limiting cam 59 conflicts with the limiting sieve plate 51 during the rotation process, the limiting sieve plate 51 automatically moves upward due to the conflict, and the limiting sieve plate 51 moves to the The upward movement will automatically drive the limiting T-shaped block 52 to slide inside the limiting T-shaped groove 53. At this time, the return spring 54 is in a contracted state due to the interference of the limiting T-shaped block 52. When the limiting cam 59 does not interfere with the limiting screen plate 51 during the rotation process, the return spring 54 is no longer squeezed by the limiting T-shaped block 52 and will automatically push the limiting T-shaped block 52 to move down and reset, thereby driving the limiting screen plate 51 to reset. In this back and forth vibration process, the large particles of impurities in the metal micropowder are separated from the metal powder through the vibration of the limiting screen plate 51.

[0027] The limiting sieve plate 51 is set to a porous sieve plate structure, and the height of the protective plate 55 is greater than the slot height of the limiting T-shaped slot 53; the specific shape of the limiting sieve plate 51 is described here to facilitate the above-mentioned screening to be carried out smoothly, and the height of the protective plate 55 is set to be greater than the slot height of the limiting T-shaped slot 53, so that the above-mentioned limiting sieve plate 51 can always cover the limiting T-shaped slot 53 through the protective plate 55 during the up and down displacement process, thereby preventing metal powder from entering the inside of the limiting T-shaped slot 53.

[0028] When the present invention is in use, when it is necessary to collect the residual silver powder on the processing table into the interior of the device, it is first necessary to install a docking hose through the flange on the limiting conduit 36, align the hose with the position of the silver powder to be collected, and then start the driving motor 32. When the driving motor 32 is turned on, it will automatically drive the driving shaft 33 to rotate and then drive the limiting fan 34 to rotate. It is noted here that the limiting fan 34 is set to be installed in reverse. When it rotates, it will draw the silver powder on the workbench into the inside of the hose by negative pressure extraction and then transport it to the inside of the device. Here, due to the setting of the protective filter installed inside the limiting mounting plate 35, when the air flow carrying silver powder passes through the protective filter, the silver powder will be automatically isolated outside the protective filter; when the above-mentioned limiting fan 34 rotates, it will also synchronously drive the support shaft to rotate and then drive the limiting scraper 41 to rotate. When the limiting scraper 41 rotates, it will automatically push the silver powder adhered to the negative pressure outside the protective filter through the feed chute 42 to the top of the limiting screen plate 51 through the inertial push, thereby achieving the effect of centralized collection. When it is necessary to separate the silver powder accumulated above the limit screen plate 51 into large and small particles, the control motor 57 needs to be turned on first. The auxiliary support plate 56 here is provided to assist the control motor 57. When the control motor 57 is turned on, it will automatically drive the transmission shaft 58 to rotate and then drive the limit cam 59 to rotate. When the limit cam 59 conflicts with the limit screen plate 51 during the rotation process, the limit screen plate 51 automatically moves upward due to the conflict, and the limit screen plate 51 automatically moves upward. The movable limit T-shaped block 52 slides inside the limit T-shaped groove 53. At this time, the return spring 54 is in a contracted state due to the interference of the limit T-shaped block 52. When the limit cam 59 does not interfere with the limit screen plate 51 during the rotation process, the return spring 54 is no longer squeezed by the limit T-shaped block 52 and will automatically push the limit T-shaped block 52 downward to reset, thereby driving the limit screen plate 51 to reset. In this back-and-forth vibration process, the large particles of impurities in the metal micropowder are separated from the metal powder through the vibration of the limit screen plate 51.

[0029] It is noted here that the above-mentioned drive motor 32 and control motor 57 can be powered by existing technology. Whether it is powered by a power supply component or an external wire, it is all existing conventional operating technical means and will not be described in detail here.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
