Description

Technical Field

[0001] This utility model relates to the field of silver powder processing technology, and in particular to a centrifugal sedimentation device for silver powder processing. Background Technology

[0002] Silver powder, also known as aluminum powder, is typically added to paint as a special pigment to prepare silver powder paint. Centrifugal sedimentation machines are frequently used in the processing of silver powder. These machines utilize a high-speed rotating motor to generate significant centrifugal force, causing mixtures of different densities and sizes to settle and separate at different speeds. However, existing centrifugal devices used in silver powder processing still have some problems:

[0003] Existing centrifugal devices for silver powder processing cannot adjust the centrifugal speed during use; they can only rotate at a single speed to centrifuge the silver powder. However, in actual centrifugation, a single speed is insufficient to centrifuge multiple substances of different densities, resulting in poor centrifugation efficiency when centrifuging multiple mixtures. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a centrifugal sedimentation device for silver powder processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centrifugal precipitation device for silver powder processing includes a processing chamber. A frustum-shaped shell is welded to the inner wall of the middle part of the processing chamber, and a rotating shaft is rotatably mounted in the middle of the frustum-shaped shell. A fixed disc is welded to the top outer wall of the rotating shaft, and a centrifuge cylinder is fixed to the top of the fixed disc by bolts. A feed pipe is connected to the top axis of the centrifuge cylinder, and a sealing cover is fixed to the top of the processing chamber. Arc-shaped baffles are welded to the inner walls of all four sides of the processing chamber, and a discharge pipe is connected to one inner wall of the frustum-shaped shell. A driven gear is welded to the bottom outer wall of the rotating shaft, and a driving gear meshes with one side of the driven gear. A first servo motor is connected to the bottom axis of the driving gear.

[0007] As a further embodiment of this utility model: a feeding hopper is provided in the middle of the sealing cover, and the bottom of the feeding hopper is inserted into the inner wall of the top of the feeding pipe, and the inner wall size of the feeding pipe is adapted to the outer wall size of the bottom of the feeding hopper.

[0008] As a further improvement of this utility model: support legs are welded to the four corners of the bottom of the processing box, and heat dissipation slots are evenly distributed through the outer walls on both sides of the processing box.

[0009] As a further embodiment of this utility model: a first synchronous pulley is fixed to the bottom outer wall of the rotating shaft, and a synchronous belt is engaged with the outer wall of the first synchronous pulley. A second synchronous pulley is provided on the other side of the synchronous belt, and a second servo motor is connected to the bottom axis of the second synchronous pulley.

[0010] As a further improvement of this utility model: the bottom outer wall of the sealing cover is fixed with an annular slide rail, and an electric slider is slidably inserted into the inner wall of the annular slide rail. The bottom of the electric slider is fixed with a double-layer rubber scraper by screws.

[0011] As a further improvement of this utility model: the size of the annular slide rail is adapted to the inner wall size of the processing box, and the outer wall of the double-layer rubber scraper is in close contact with the inner wall of the processing box.

[0012] As a further embodiment of this utility model: the ratio of the effective number of teeth of the driving gear to the effective number of teeth of the driven gear is 3:1, and the ratio of the effective number of teeth of the second synchronous pulley to the effective number of teeth of the first synchronous pulley is 3:1.

[0013] Compared with the prior art, the present invention provides a centrifugal sedimentation device for silver powder processing, which has the following beneficial effects:

[0014] 1. The centrifugal sedimentation device for silver powder processing designed in this paper uses a driven gear and a driving gear that mesh with each other at the bottom of the centrifuge cylinder to achieve rapid rotation and centrifugation of the mixture. When the centrifugation effect is not good during the centrifugation of multiple mixtures, a second servo motor can be started to drive the first synchronous pulley for auxiliary processing, realizing a second-stage acceleration of the centrifuge cylinder, so that the centrifuge device can further meet the centrifugation requirements of mixtures with different densities.

[0015] 2. The centrifugal sedimentation device for silver powder processing designed in this paper utilizes an electric slider to drive a double-layer rubber scraper to rotate during the centrifugation process to facilitate subsequent sedimentation. This cleans and scrapes the inner wall of the processing chamber, reduces the contamination of the mixture after centrifugation, and improves the sedimentation effect.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1:

[0024] A centrifugal precipitation apparatus for silver powder processing, in this embodiment, as follows: Figure 1-4 As shown, the processing box 1 includes a frustum shell 2 welded to the inner wall of the middle part of the processing box 1, and a rotating shaft 3 rotatably mounted in the middle of the frustum shell 2. A fixed disc 4 is welded to the outer top of the rotating shaft 3, and a centrifuge cylinder 5 is fixed to the top of the fixed disc 4 by bolts. A feed pipe 6 is connected to the top axis of the centrifuge cylinder 5, and a sealing cover 8 is fixed to the top of the processing box 1. Arc-shaped baffles 7 are welded to the inner walls of the four sides of the processing box 1, and a discharge pipe 10 is connected to the inner wall of one side of the frustum shell 2. A driven gear 13 is welded to the outer bottom of the rotating shaft 3, and a driving gear 14 is meshed and driven on one side of the driven gear 13. A first servo motor 15 is connected to the bottom axis of the driving gear 14.

[0025] By setting a driven gear 13 and a driving gear 14 meshing with each other at the bottom of the centrifuge cylinder 5, it can be made to rotate quickly to achieve centrifugation of the mixture. When the centrifugation effect is not good during the centrifugation of multiple mixtures, the second servo motor 19 can be started to drive the first synchronous pulley 16 for auxiliary processing, realizing the secondary acceleration of the centrifuge cylinder 5, so that the centrifuge device can further meet the centrifugation requirements of mixtures with different densities.

[0026] The sealing cover 8 is provided with a feeding hopper 9 in the middle, and the bottom of the feeding hopper 9 is inserted into the top inner wall of the feeding pipe 6. The inner wall size of the feeding pipe 6 is adapted to the bottom outer wall size of the feeding hopper 9. Support legs 11 are welded to the four corners of the bottom of the processing box 1, and heat dissipation slots 12 are evenly distributed through the outer walls on both sides of the processing box 1.

[0027] The bottom outer wall of the rotating shaft 3 is fixed with a first synchronous pulley 16, and the outer wall of the first synchronous pulley 16 is engaged with a synchronous belt 17. The other side of the synchronous belt 17 is provided with a second synchronous pulley 18, and a second servo motor 19 is connected to the bottom axis of the second synchronous pulley 18.

[0028] The bottom outer wall of the sealing cover 8 is fixed with an annular slide rail 20, and an electric slider 21 is slidably inserted into the inner wall of the annular slide rail 20. The bottom of the electric slider 21 is fixed with a double-layer rubber scraper 22 by screws.

[0029] During the centrifugation process of silver powder, in order to facilitate the subsequent precipitation process, the electric slider 21 drives the double-layer rubber scraper 22 to rotate during the centrifugation process, thereby cleaning and scraping the inner wall of the processing box 1, reducing the impurities in the mixture after centrifugation, and improving the precipitation effect.

[0030] In this embodiment, the centrifugal sedimentation device is first assembled. After assembly, the sealing cover 8 is fixed to the top of the processing box 1, and the feed hopper 9 is aligned with the inner wall of the feed pipe 6. After that, the mixture to be centrifuged is poured into the feed hopper 9. The first servo motor 15 at the bottom is started first, and the first servo motor 15 drives the drive gear 14 to rotate, thereby meshing and driving the driven gear 13 to rotate, realizing the rotation of the rotating shaft 3, thereby driving the rotation of the top centrifugal cylinder 5 to centrifuge the mixture. During the centrifugation process, the electric slider 21 is started to drive the double-layer rubber scraper 22 to rotate, thereby cleaning the centrifuged material on the inner wall of the processing box 1, which facilitates subsequent sedimentation and reduces the interference of stratification. When a single speed cannot meet the centrifugation requirements of multiple mixtures, the second servo motor 19 is started to drive the first synchronous pulley 16 to rotate, thereby achieving a two-stage acceleration process for the centrifugal cylinder, thereby improving the centrifugation effect.

The effective number of teeth of the driving gear 14 is 3:1 to the effective number of teeth of the driven gear 13, and the effective number of teeth of the second synchronous pulley 18 is 3:1 to the effective number of teeth of the first synchronous pulley 16.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
