Description

Technical Field

[0001] This utility model belongs to the field of brazing material processing technology, specifically relating to a vacuum dispersion device for paste-like brazing materials. Background Technology

[0002] The paste-like brazing material undergoes vacuum dispersion during stirring to effectively remove air bubbles generated during the stirring process. The material is uniformly dispersed in a vacuum environment, preventing oxidation or bubble formation that could affect product quality. Paste-like brazing materials are prone to bubble formation during preparation, impacting the quality of the weld joint. Vacuum technology helps the paste-like brazing material coat the welding surface better, improving weld quality. Metal powder, flux, and a portion of the organic carrier are added to a mixing tank and stirred at low speed to form a preliminary paste. Vacuum dispersion is then initiated, and the vacuum pump is started while stirring continues for a period of time to remove air bubbles.

[0003] During vacuum dispersion, the metal powder, flux, and organic carrier are not mixed evenly, resulting in agglomeration or stratification. To avoid this phenomenon, the dispersion time needs to be increased, which affects the production efficiency. Utility Model Content

[0005] This utility model provides the following technical solution: a vacuum dispersion device for a paste-like brazing material, comprising a vacuum dispersion body, a dispersion cylinder on the vacuum dispersion body, a dispersion chamber for vacuum dispersion of the material on the dispersion cylinder, a stirring shaft rotatably connected inside the dispersion chamber, a plurality of stirring blades fixedly installed on the stirring shaft, a transverse feeding assembly between every two stirring blades, the transverse feeding assembly comprising a transverse dispersion feeding cylinder, a feeding plate and a transverse dispersion shaft, a plurality of transversely distributed transverse dispersion stirring plates fixedly connected to the outside of the transverse dispersion shaft, the transverse dispersion stirring plates being perpendicular to the stirring blades.

[0006] The transverse dispersion feeding cylinder is fixedly connected to the vacuum disperser body, and the transverse dispersion feeding cylinder has several feed holes.

[0007] The feeding disc is fixedly connected to the front end of the transverse dispersing and feeding cylinder, and the transverse dispersing and feeding cylinder has an open hole.

[0008] The transverse dispersion and positioning cylinder is hollow inside, and the open hole is connected to the inside of the transverse dispersion and positioning cylinder.

[0009] The transverse dispersion feeding cylinder is equipped with a motor for driving the transverse dispersion shaft to rotate, and the center line of the transverse dispersion shaft coincides with the center line of the transverse dispersion feeding cylinder.

[0010] The feed hole is opposite to the outer wall of the transverse dispersion shaft, and the transverse dispersion stirring plate is located between every two feed holes.

[0011] The paste-like brazing material is located inside the dispersion cavity and is in contact with the outer wall of the transverse dispersion and positioning cylinder.

[0012] The beneficial effects of this utility model are:

[0013] The transverse feeding assembly includes a transverse dispersing feeder, a feeding disc, and a transverse dispersing shaft. When the material is processed inside the vacuum disperser, the stirring shaft acts on the material, and the transverse dispersing feeder, which is distributed laterally, allows the material to enter. The rotation of the transverse dispersing shaft drives the transverse dispersing and stirring blades to process the material, increasing the dispersion space of the material and avoiding agglomeration, thereby improving the efficiency of paste brazing material production.

[0021] In this embodiment: a dispersion cylinder 11 is provided on the vacuum disperser body 1. The dispersion cylinder 11 has a dispersion chamber 12 for vacuum dispersion of materials. A stirring shaft 2 is rotatably connected inside the dispersion chamber 12. Several stirring blades 21 are fixedly installed on the stirring shaft 2. When the vacuum disperser body 1 is started, the stirring shaft 2 drives the stirring blades 21 to rotate, so that the paste brazing material is vacuum dispersed while being stirred, effectively removing air bubbles generated during the stirring process. The transverse feeding assembly 3 includes a transverse dispersion feeding cylinder 31, a feeding plate 33, and a transverse dispersion shaft 34. Several transversely distributed transverse dispersion stirring plates 341 are fixedly connected to the outside of the transverse dispersion shaft 34. The transverse dispersion stirring plates 341 and the stirring blades 21 are connected to each other. 1. Vertically distributed, when the material is processed inside the vacuum disperser 1, the stirring shaft 2 acts on the material, and it passes through the transversely distributed dispersing feed cylinder 31, which is fixedly connected to the vacuum disperser 1. The transverse dispersing feed cylinder 31 has several feed holes 311, and the feeding plate 33 is fixedly connected to the front end of the transverse dispersing feed cylinder 31. The transverse dispersing feed cylinder 31 has an open hole 331, which allows the material to enter. The material enters through the open hole 331 and the feed hole 311. The transverse dispersing shaft 34 rotates, driving the transverse dispersing stirring plate 341 to process the material, increasing the dispersion space of the material, avoiding agglomeration, and thus improving the efficiency of paste brazing material production.

[0022] The interior of the transverse dispersion feeding cylinder 31 is hollow, and the open hole 331 is connected to the interior of the transverse dispersion feeding cylinder 31; when the material is stirred in the dispersion chamber 12, it can come into contact with the outside of the feeding plate 33, which is beneficial to improve the stirring effect.

The material enters through the feed hole 311 and is stirred by the transverse dispersion stirring plate 341. After the work is completed, the transverse dispersion shaft 34 is in a stationary state, and the material is discharged from the feed hole 311.

[0025] The paste-like brazing material is located inside the dispersion chamber 12 and is in contact with the outer wall of the transverse dispersion feeding cylinder 31. When the material is stirred inside the dispersion chamber 12, it can come into contact with the outside of the transverse dispersion feeding cylinder 31, which helps to improve the stirring effect.

[0026] The working principle and usage process of this utility model are as follows: When the vacuum disperser 1 is started, the stirring shaft 2 drives the stirring blades 21 to rotate, so that the paste-like brazing material is vacuum dispersed while being stirred, effectively removing air bubbles generated during the stirring process. The transverse feeding assembly 3 includes a transverse dispersion feeding cylinder 31, a feeding plate 33, and a transverse dispersion shaft 34. Several transversely distributed transverse dispersion stirring blades 341 are fixedly connected to the outside of the transverse dispersion shaft 34. The transverse dispersion stirring blades 341 are distributed perpendicularly to the stirring blades 21. When the material is being processed inside the vacuum disperser 1, the stirring shaft 2 acts on the material. Furthermore, the transversely distributed dispersing feed cylinder 31 is fixedly connected to the vacuum disperser body 1. The transversely distributed dispersing feed cylinder 31 has several feed holes 311. The feeding plate 33 is fixedly connected to the front end of the transversely distributed dispersing feed cylinder 31. The transversely distributed dispersing feed cylinder 31 has an open hole 331, which allows materials to enter into it. The materials enter through the open hole 331 and the feed holes 311. The transversely distributed shaft 34 rotates to drive the transversely distributed stirring plate 341 to process the materials, increasing the dispersion space of the materials and avoiding agglomeration, thereby improving the efficiency of paste brazing material production.
