Description

Technical Field

[0001] This utility model relates to the field of atomized aluminum powder technology, specifically to an atomized aluminum powder settling chamber. Background Technology

[0002] Atomized aluminum powder is a material produced by converting molten aluminum into powder using atomization technology. Specifically, atomized aluminum powder is produced by atomizing molten aluminum into fine droplets using atomization equipment (such as water atomization and gas atomization), and then rapidly cooling and solidifying it into powder in air. This method produces aluminum powder with uniform particle size, good distribution, high purity, and high activity. Water atomization uses water as a medium, resulting in lower cost, but relatively lower powder purity. Gas atomization uses inert gases such as nitrogen or argon as a medium, producing high-purity aluminum powder. Currently, gas atomization equipment is mostly used to prepare atomized aluminum powder. The resulting atomized aluminum powder needs to be collected in a settling chamber. Commonly used atomized aluminum powder settling chambers have simple structures, including a cylinder with cooling water pipes and a collection chamber. These chambers have low collection efficiency and cannot achieve complete recovery of the atomized aluminum powder. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an atomized aluminum powder settling chamber that can perform three-stage settling of atomized aluminum powder to achieve comprehensive recovery of atomized aluminum powder.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A settling chamber for atomized aluminum powder includes a settling chamber body and a cooling layer located outside the settling chamber body. The settling chamber body has three interconnected cavities inside, namely a first settling chamber, a second settling chamber, and a third settling chamber. The lower ends of the first settling chamber, the second settling chamber, and the third settling chamber are respectively provided with a discharge chamber and a discharge port. The first settling chamber is provided with a feed port, and the third settling chamber is provided with an air outlet.

[0006] A first baffle and a second baffle are arranged one above the other between the first and second settling chambers, with a gap between the first and second baffles; a third baffle and a fourth baffle are arranged one above the other between the second and third settling chambers, with a gap between the third and fourth baffles; a fifth baffle is installed in the first, second, and third settling chambers.

[0007] Furthermore, a vibrator is installed on the outer side of the discharge chamber.

[0008] Furthermore, the first baffle, the second baffle, the third baffle, and the fourth baffle are all... The shape is such that the first and third baffles are located at the upper part of the interior of the settling chamber body, and the second and fourth baffles are located at the bottom of the interior of the settling chamber body.

[0009] Furthermore, the left and right sides of the fifth baffle are disposed on the settling chamber body, and there are gaps between the upper and lower ends and the settling chamber body.

[0010] Furthermore, cooling water inlets connected to the cooling layer are provided on both sides of the lower end of the settling chamber body, and cooling water outlets connected to the cooling layer are provided at the upper end of the settling chamber body.

[0011] Furthermore, the first baffle, second baffle, third baffle, fourth baffle, and fifth baffle are all hollow structures and are connected to the cooling layer.

[0012] Furthermore, the lower ends of the first and third baffles, the upper ends of the second and fourth baffles, and both ends of the fifth baffle are conical.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The atomized aluminum powder settling chamber provided by this utility model includes three settling chambers, which can perform three-stage settling of atomized aluminum powder. Each settling chamber is equipped with a baffle. The fifth baffle is set opposite to the feed inlet. When the atomized aluminum powder enters the settling chamber, it can collide with the baffle immediately and decelerate, effectively achieving the settling of the atomized aluminum powder under the action of gravity. The atomized aluminum powder that has not been settled continues to collide with the first and second baffles through the gaps between the upper and lower ends of the fifth baffle, which can further decelerate the atomized aluminum powder. Under the action of the three-stage settling chamber, the atomized aluminum powder can be fully recovered, reducing the waste of atomized aluminum powder.

[0015] (2) In this utility model, the first baffle, the second baffle, the third baffle, and the fourth baffle are all The atomized aluminum powder, upon impacting the baffle, can bounce back to an adjacent baffle, thus achieving secondary deceleration. This, to some extent, extends the movement path of the atomized aluminum powder, allowing for more thorough cooling and improving its settling efficiency. Furthermore, the baffle is designed as... The shape allows atomized aluminum powder to accumulate on the surface of the baffle.

[0016] (3) The present invention is equipped with a vibrator on the discharge chamber. Through the action of the vibrator, all the atomized aluminum powder on the inner wall of the discharge chamber can be discharged, preventing the atomized aluminum powder from accumulating on the inner wall of the discharge chamber.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, this embodiment provides an atomized aluminum powder settling chamber, including a settling chamber body 1. The settling chamber body 1 has three interconnected cavities: a first settling chamber 2, a second settling chamber 3, and a third settling chamber 4. Each of the first, second, and third settling chambers 2, 3, and 4 has a discharge chamber 5 at its lower end. Each discharge chamber 5 has a discharge port 17 at its lower end. A vibrator 6 is installed on the outer surface of the discharge chamber 5. During the atomized aluminum powder settling process, the vibrator 6 is activated to prevent the atomized aluminum powder from accumulating on the inner wall of the discharge chamber 5, achieving complete discharge. A first baffle 7 and a second baffle 8 are provided between the first settling chamber 2 and the second settling chamber 3. Both the first baffle 7 and the second baffle 8 are... Shaped, and positioned vertically. The inflection point of the baffle is located in the second settling chamber 3. The first baffle 7 is located at the upper end of the settling chamber body 1, and the second baffle 8 is located on the inner bottom surface of the settling chamber body 1, with a certain gap between the first baffle 7 and the second baffle 8. The second settling chamber 3 and the third settling chamber 4 are separated by the third baffle 9 and the fourth baffle 10. The shape and installation method of the third baffle 9 are the same as those of the first baffle 7, and the shape and installation method of the fourth baffle 10 are the same as those of the second baffle 8. In this embodiment, the first baffle 7, the second baffle 8, the third baffle 9, and the fourth baffle 10 are all installed vertically. A fifth baffle 11 (e.g., ...) is also installed in the first settling chamber 2, the second settling chamber 3, and the third settling chamber 4. Figure 2 As shown, the left and right sides of the fifth baffle 11 are set on the settling chamber body 1, and the upper and lower ends are separated from the settling chamber body 1 by gaps.

[0023] A feed inlet 12 is provided on the side of the first settling chamber 2 without a baffle, and an air outlet 13 is provided on the side of the third settling chamber 4 without a baffle. A cooling layer 14 is provided on the outer surface of the settling chamber body 1. The cooling layer 14 is water-cooled. Figure 2As shown, cooling water inlets 15 connected to the cooling layer 14 are provided on both sides of the lower end of the settling chamber body 1, and cooling water outlets 16 connected to the cooling layer 14 are provided at the upper end of the settling chamber body 1.

[0024] In this embodiment, a base 19 is provided below the discharge port 17, and a support frame 18 is installed on the base 19 to support the settling chamber body 1. A collection chamber 20 is provided on the base 19, located directly below the discharge port 17. The atomized aluminum powder discharged from the discharge port 17 directly enters the collection chamber 20 for centralized collection. The lower ends of the first baffle 7 and the third baffle 9, the upper ends of the second baffle 8 and the fourth baffle 10, and both ends of the fifth baffle 11 are all designed as conical to prevent the atomized aluminum powder from accumulating on the baffles.

[0025] In the process of using the atomized aluminum powder settling chamber provided in this embodiment, air (or inert gas) and atomized aluminum powder enter the first settling chamber 2 from the feed inlet 12. The cooling layer 14 outside the settling chamber body 1 cools the atomized aluminum powder. At the same time, the aluminum powder is decelerated by hitting the fifth baffle 11. Under the action of gravity, the atomized aluminum powder moves downward into the discharge chamber 5 and is finally discharged from the discharge outlet 11 into the collection chamber. The atomized aluminum powder that is not collected by the first settling chamber 2 continues to move forward with the air through the gaps above and below the fifth baffle 11. Part of it impacts the first baffle 7 and the second baffle 8 and is intercepted. The remaining part enters the second settling chamber 3 through the gap between the first baffle 7 and the second baffle 8. In the second settling chamber 3, it continues to be cooled by the cooling layer 14 and impacts the fifth baffle, the third baffle 9, and the fourth baffle 10, where it is slowed down and settling again. After settling in the second settling chamber 3, the air contains only a small amount of atomized aluminum powder. The air and the small amount of atomized aluminum powder continue to settle in the third settling chamber 4. The settled atomized aluminum powder enters the collection chamber below the device, and the remaining air is discharged from the air outlet 13.

[0026] Example 2

[0027] The atomized aluminum powder settling chamber provided in this embodiment is based on Embodiment 1, with the first baffle 7, second baffle 8, third baffle 9, fourth baffle 10, and fifth baffle 11 designed as hollow structures, and the cooling layer 14 connected to the hollow baffles. When collecting atomized aluminum powder using the settling chamber provided in this embodiment, cooling water can be introduced into the first baffle 7, second baffle 8, third baffle 9, fourth baffle 10, and fifth baffle 11. When the atomized aluminum powder impacts the baffles, it is decelerated and rapidly cooled, accelerating its settling rate.

[0028] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
