Description

Technical Field

[0001] This utility model patent relates to the field of powder screening equipment processing technology, and mainly relates to a metal powder screening device. Background Technology

[0002] After metal is atomized and powdered, it needs to be screened by a grading and screening device. Most existing grading and screening devices have two or more screens. Large metal powder particles will remain on the screens, while small metal powder particles will fall through the screens and fall onto screens with smaller apertures for further screening. Using multi-stage screens can separate metal powders of different particle sizes. Although grading and screening can be performed, the screening efficiency is low and it is easy to cause filter clogging. To address this, we propose a metal powder screening device. Utility Model Content

[0004] To achieve the above objectives, the following technical solution is provided: A metal powder screening device includes a support frame, a screening mechanism connected to the top of the support frame, the screening mechanism including a rotating motor connected to one side of the top of the support frame, a large gear connected to the drive end of the rotating motor, a rotating shaft connected to one side of the large gear, and a spiral blade connected to the outer wall of one side of the rotating shaft. A screening assembly is rotatably connected to one side of the rotating shaft. The screening assembly includes a fixed cylinder connected to one side of the top of the support frame, a first screening cylinder rotatably connected to one side of the fixed cylinder, and a second screening cylinder connected to one side of the first screening cylinder. One end of the second screening cylinder is rotatably connected to the support frame, and an internal gear is connected to the inner wall of one end of the second screening cylinder. A small gear is meshed with one side of the internal gear, and a bracket is rotatably connected to one side of the small gear. The small gear meshes with the large gear.

[0005] The top of the support is connected to a guide box, which is located at the bottom of the screening component.

[0006] Furthermore, the top of the fixed cylinder is provided with a feed inlet, and a rotating shaft is rotatably connected to one side inside the fixed cylinder.

[0007] Furthermore, a fixing ring is fixed at the end of the second screening cylinder away from the first screening cylinder, one side of the fixing ring is rotatably connected to a bracket, and one side of the inner wall of the fixing ring is connected to an internal gear.

[0008] Furthermore, the second screening cylinder has multiple discharge ports on the side away from the first screening cylinder.

[0009] Furthermore, multiple baffles are fixed inside the guide box, and the guide box and the multiple baffles form multiple feeding chambers. The bottom of the feeding chamber is provided with a feeding port on the side away from the rotating motor. The multiple feeding chambers correspond to the first screening cylinder, the second screening cylinder and the discharge port, respectively.

[0010] Furthermore, the bottom upper surface of the support is connected to multiple storage boxes of different sizes, and each storage box corresponds to a discharge port.

[0011] Furthermore, the fixed cylinder, the first screening cylinder, and the second screening cylinder are connected to form a screening chamber. The fixed cylinder, the first screening cylinder, the second screening cylinder, and the guide box are inclined, and the height of the fixed cylinder is less than that of the first screening cylinder, and the height of the first screening cylinder is less than that of the second screening cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention provides a metal powder screening device. Metal powder can be added at any time through the feed inlet. A rotating motor drives a large gear and a rotating shaft to rotate, thereby rotating the spiral blades and conveying the metal powder. The large gear drives a small gear to rotate, which in turn drives an internal gear, a first screening cylinder, and a second screening cylinder to rotate. When the powder entering the sieve holes rotates to the top, the powder falls due to gravity, preventing the metal powder from clogging the sieve holes. The first screening cylinder, the second screening cylinder, and the discharge port can perform multi-stage screening of the metal powder. Furthermore, since the rotation direction of the first and second screening cylinders is opposite to the rotation direction of the rotating shaft and the spiral blades, the conveying and screening speed of the metal powder can be improved.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0020] For an example, please refer to... Figure 1-3 The metal powder screening device includes a support 10, with a screening mechanism 20 connected to the top of the support 10. The screening mechanism 20 includes a rotating motor 21 connected to one side of the top of the support 10, a large gear 22 connected to the drive end of the rotating motor 21, a rotating shaft 23 connected to one side of the large gear 22, and a spiral blade 24 connected to the outer wall of one side of the rotating shaft 23. A screening assembly 25 is rotatably connected to one side of the rotating shaft 23. The screening assembly 25 includes a fixed cylinder 251 connected to one side of the top of the support 10, a first screening cylinder 252 rotatably connected to one side of the fixed cylinder 251, and a second screening cylinder 253 connected to one side of the first screening cylinder 252. One end of the second screening cylinder 253 is rotatably connected to the support 10, and the inner wall of one end of the second screening cylinder 253 is connected to an internal gear 26. One side of the internal gear 26 is meshed with a small gear 27, and one side of the small gear 27 is rotatably connected to the support 10. The small gear 27 is meshed with the large gear 22.

[0021] The top of the bracket 10 is connected to the guide box 40, which is located at the bottom of the screening component 25.

[0022] It should be noted that in this embodiment, both the first screening cylinder 252 and the second screening cylinder 253 are provided with multiple sieve holes, and the sieve holes on the first screening cylinder 252 are smaller than those on the second screening cylinder 253, which can realize the screening of metal powders of different sizes. By rotating the motor 21, the large gear 22 and the rotating shaft 23 are driven to rotate, thereby causing the spiral blade 24 to rotate, realizing the conveying of metal powder. The large gear 22 drives the small gear 27 to rotate, thereby driving the internal gear 26, the first screening cylinder 252 and the second screening cylinder 253 to rotate. When the powder entering the sieve hole rotates to the top, the powder falls down due to gravity, avoiding the metal powder from clogging the sieve hole. Since the rotation direction of the first screening cylinder 252 and the second screening cylinder 253 is opposite to the rotation direction of the rotating shaft 23 and the spiral blade 24, the conveying rate of metal powder can be improved.

[0023] For an example, please refer to... Figure 3 The top of the fixed cylinder 251 is provided with a feed inlet 2511, and the inside of the fixed cylinder 251 is rotatably connected to a rotating shaft 23.

[0024] It should be noted that in this embodiment, the operator can add metal powder at any time through the feed inlet 2511.

[0025] For an example, please refer to... Figure 2-3 The second screening cylinder 253 has a fixing ring 2531 fixed at one end away from the first screening cylinder 252. The fixing ring 2531 is rotatably connected to the bracket 10 on one side, and the inner wall of the fixing ring 2531 is connected to the internal gear 26.

[0026] For an example, please refer to... Figure 2-3 The second screening cylinder 253 has multiple discharge ports 2532 on the side away from the first screening cylinder 252.

[0027] Multiple baffles 41 are fixed inside the guide box 40. The guide box 40 and the multiple baffles 41 form multiple feeding chambers. The bottom of the feeding chamber is provided with a feeding port 42 on the side away from the rotating motor 21. The multiple feeding chambers correspond to the first screening cylinder 252, the second screening cylinder 253 and the discharge port 2532 respectively.

[0028] It should be noted that in this embodiment, the first screening cylinder 252 can screen out smaller powders, and the second screening cylinder 253 can screen out larger powders. Powders not screened out by the first screening cylinder 252 and the second screening cylinder 253 are discharged from the second screening cylinder 253 through the discharge port 2532. The baffle 41 can divide the guide box 40 into multiple feeding chambers, so that different powders screened out enter different feeding chambers.

[0029] For an example, please refer to... Figure 1-3 The bottom upper surface of the support 10 is connected to multiple storage boxes 30 of different sizes, and each storage box 30 corresponds to a discharge port 42.

[0030] The fixed cylinder 251, the first screening cylinder 252, and the second screening cylinder 253 are connected to form a screening chamber. The fixed cylinder 251, the first screening cylinder 252, the second screening cylinder 253, and the guide box 40 are inclined. The height of the fixed cylinder 251 is less than that of the first screening cylinder 252, and the height of the first screening cylinder 252 is less than that of the second screening cylinder 253.

[0031] It should be noted that in this embodiment, the fixed cylinder 251, the first screening cylinder 252 and the second screening cylinder 253 are inclined to prevent the metal powder from sliding quickly to the discharge port 2532 and to avoid the powder from being incompletely screened. The guide box 40 is inclined to facilitate the screening of the powder to slide to the discharge port 42 and fall into the corresponding storage box 30.

[0032] The specific operation method of this utility model is as follows:

[0033] The aforementioned metal powder screening device first introduces metal powder through the feed inlet 2511. Then, the rotating motor 21 drives the large gear 22 and the rotating shaft 23 to rotate, thereby rotating the spiral blade 24 and conveying the metal powder. The large gear 22 drives the small gear 27 to rotate, which in turn drives the internal gear 26, the first screening cylinder 252, and the second screening cylinder 253 to rotate. When the powder entering the sieve holes rotates to the top, the powder falls due to gravity, preventing the metal powder from clogging the sieve holes. The metal powder is screened as it passes through the first screening cylinder 252 and the second screening cylinder 253, and the screened metal powder falls into the guide box 40. The powder that is not screened by the first screening cylinder 252 and the second screening cylinder 253 is discharged from the second screening cylinder 253 through the discharge port 2532. Since the rotation direction of the first screening cylinder 252 and the second screening cylinder 253 is opposite to the rotation direction of the rotating shaft 23 and the spiral blade 24, the conveying rate of the metal powder can be improved.

[0034] The above embodiments merely illustrate the implementation methods of this application. However, those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
