Description

Technical Field

[0001] This utility model relates to the field of atomization device technology, and in particular to a copper powder preparation water atomization device with recycling function. Background Technology

[0002] Copper powder is a key raw material for powder metallurgy and 3D printing; and high-pressure water atomization is a common process for preparing copper powder. Optimizing it can help meet the relevant needs of 3D printing.

[0003] The steps for producing copper powder by high-pressure water atomization are as follows: First, the copper solution is superheated to about 50 degrees Celsius and injected into the guiding mechanism; then, the water injection mechanism is activated, and the copper solution falls and breaks into several copper droplets under the action of high-pressure water; next, the copper droplets enter the atomization container through the guiding mechanism, and the atomization container contains a cooling medium; at this time, the copper droplets fall into the cooling medium and gradually solidify into copper powder.

[0004] In existing technologies, in order to achieve a vacuum environment inside the atomizing container, an exhaust pipe is usually installed on one side of the atomizing container to lead out the air inside the atomizing container. However, in actual use, the exhaust pipe will discharge the inert gas in the atomizing tower container along with the air to the outside, which generally leads to unnecessary waste of inert gas.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0074] Example 1

[0075] As attached Figure 1-4 As shown in the figure, this embodiment discloses a copper powder preparation water atomizing device with recycling function, which is used to recycle the inert gas in the atomizing container 3. It mainly includes a mounting base 1, a support frame 2, a filter plate 9, an atomizing container 3, a guiding mechanism 4, a water injection mechanism 5, and an inert gas circulation mechanism 7. In use, first operate the controller (not shown in the figure) to keep the copper powder extraction component 37 closed; then, inject an appropriate amount of cooling medium into the atomizing container 3; then, press the corresponding button on the controller to start the inert gas circulation mechanism 7; the air in the atomizing container 3 is gradually drawn to the exhaust gas treatment unit 72, which separates the inert gas from the extracted air and directly delivers it to the atomizing container 3, thereby forcing out the air in the cooling medium, including oxidizing gases; the inert gas is generally nitrogen, which leaves the cooling medium in the form of bubbles after entering the cooling medium, and is drawn out along with other air; then, it re-enters the exhaust gas treatment unit 72; after a period of time, the environment inside the atomizing container 3 gradually becomes a vacuum environment; then, copper solution is injected; at this time, the controller... The water injection mechanism 5 is activated, and the water injection mechanism 5 can continuously spray high-pressure water towards the copper droplet outlet through the guide mechanism 4 to prepare to break the copper solution located at the copper droplet outlet (not shown in the figure) into several copper droplets. These copper droplets are immersed in the cooling medium in the atomizing container 3 through the copper droplet outlet, and the copper droplets are gradually cooled into copper powder of different particle sizes. During this process, the inert gas circulation mechanism 7 continues to work. After a period of time, the corresponding button in the controller is pressed to change the state of the copper powder outlet component 37 to open. At this time, the cooling medium and copper powder will enter the support frame 2 together. However, the copper powder will remain on the filter plate 9, and the cooling medium will enter the cooling medium collection chamber 11 through the filter plate 9 and the cooling medium guide hole (not shown in the figure). Finally, the copper powder on the filter plate 9 is removed, thus completing one copper powder preparation process.

That is, other production lines of the corresponding enterprise produce nitrogen and store it in the gas storage container; when the copper powder preparation production line needs to use nitrogen, the gas storage container containing nitrogen is transported to the copper powder preparation production line; and, in the prior art, the nitrogen in the gas storage container is sent into the atomizing container 3, and the nitrogen in the atomizing container 3 is then directly discharged to the outside. However, this embodiment, by setting up an exhaust gas treatment unit 72, can recycle the nitrogen discharged from the atomizing container 3; at the same time, it also eliminates the step of transporting the gas storage container, which improves the efficiency of the staff to a certain extent.

An atomizing container 3 is fixedly installed on the top end of the support frame 2, and the bottom end of the inner wall of the atomizing container 3 is provided with... A copper powder outlet component 37 is provided, which is located on the bottom wall of the atomizing container 3. A copper droplet outlet is provided at the top of the atomizing container 3, and a guide mechanism 4 is provided above the copper droplet outlet. The bottom end of the guide mechanism 4 is fixedly connected to the top of the atomizing container 3. A water injection mechanism 5 is provided on the side of the guide mechanism 4, with its water outlet end passing through the side of the guide mechanism 4. An inert gas circulation mechanism 7 has its suction end passing through one side of the atomizing container 3, and its gas supply end passing through the other side of the atomizing container 3. An exhaust gas treatment unit 72 is provided in the inert gas circulation mechanism 7. Compared with the prior art, this utility model realizes the recycling of inert gas, avoids unnecessary consumption of inert gas to a certain extent, and reduces the preparation cost of copper powder. Therefore, it has high practicality.

[0078] Furthermore, the exhaust gas treatment unit 72 can be an air separation device, abbreviated as ASU; wherein, the air separation device can improve the purity of nitrogen, that is, it can improve the purity of nitrogen separated from the air discharged from the atomizing container 3, thereby reducing the probability of copper powder oxidation.

The left and right sides of the inner wall of the atomizing chamber 31 have air inlets 32 and air outlets 33, respectively. The top of the inner wall of the atomizing chamber 31 has a copper droplet outlet. The bottom wall of the atomizing chamber 31 is mainly composed of a first inclined plate 34, a second inclined plate 35, and a bottom plate 36.

The second inclined plate 35 and the first inclined plate 34 are symmetrically arranged on the left and right sides of the bottom plate 36. When the copper powder discharge component 37 is in the open state, the copper powder in the atomizing container 3 can be smoothly discharged under the action of the first inclined plate 34 and the second inclined plate 35, reducing the probability of copper powder accumulation and thus improving the collection efficiency of copper powder in this embodiment.

[0080] In a specific application scenario, as shown in the appendix Figure 3 As shown, the inert gas circulation mechanism 7 includes an extraction pipe 71, an air delivery pipe 73, and the aforementioned waste gas treatment unit 72. The extraction pipe 71 has an extraction end, the outer wall of which is fixedly connected to the inner wall of the air outlet 33 in the atomizing container 3. The waste gas treatment unit 72 is located at the end of the extraction pipe 71 furthest from the atomizing container 3. The air delivery pipe 73 has an air delivery end, the outer wall of which is fixedly connected to the inner wall of the air inlet 32 ​​in the atomizing container 3. The waste gas treatment unit 72 is located at the end of the air delivery pipe 73 furthest from the atomizing container 3. The exhaust gas treatment unit 72 separates nitrogen from the air drawn from the exhaust pipe 71 and delivers it directly to the air supply pipe 73. A portion of the air supply pipe 73 is vertically installed inside the atomizing container 3. The exhaust gas treatment unit 72 is electrically connected to the aforementioned controller. In use, the air supply pipe 73 is usually located below the water surface of the cooling medium. The air supply pipe 73 delivers nitrogen into the atomizing container 3, and the nitrogen enhances the heat exchange efficiency through bubble stirring. In this process, an inert atmosphere barrier can be formed, which can also achieve the purpose of rapid cooling and anti-oxidation protection of copper powder to a certain extent.

[0082] In a specific application scenario, as shown in the appendix Figure 1 Appendix Figure 3 and appendix Figure 4As shown, the guiding mechanism 4 mainly includes a connecting seat 41 and a leaking crucible 45. The connecting seat 41 is fixedly installed at the top of the atomizing container 3. The bottom end of the connecting seat 41 has a copper solution outlet 46, which is located directly above the copper droplet outlet. The top end of the connecting seat 41 has an installation cavity 44 that communicates with the copper solution outlet 46. The leaking crucible 45 is installed in the installation cavity 44 and is adapted to the installation cavity 44. In addition, the connecting seat 41 has a guiding cavity 42 on the side near the water injection mechanism 5. The guiding cavity 42 communicates directly or indirectly with the copper solution outlet 46. There are two guiding cavities 42, which are located on the left and right sides of the connecting seat 41. Of course, this embodiment has two sets of water injection mechanisms 5. In use, the water injection mechanism 5 can spray high-pressure water into the guide cavity 42, which will move to the copper solution outlet 46, thereby achieving the purpose of breaking the copper solution into several copper droplets.

[0083] Furthermore, the connecting seat 41 is also provided with a guide nozzle 43 inside; specifically, there are several guide nozzles 43, which are obliquely opened inside the connecting seat 41. The guide nozzles 43 are located between the copper solution outlet 46 and the guide cavity 42, that is, the guide cavity 42, the guide nozzles 43 and the copper solution outlet 46 are interconnected. This design allows the copper solution to fully contact the high-pressure water, thereby achieving a more uniform and efficient atomization effect; at the same time, it is beneficial to prepare copper powder with a more uniform particle size distribution in this embodiment.

[0084] In a specific application scenario, as shown in the appendix Figure 4 As shown, the water injection mechanism 5 includes a water injection pipe 51, a high-pressure water pump 52, and a guide pipe 53. The end of the water injection pipe 51 near the connecting seat 41 passes through the guide cavity 42, meaning that a portion of the outer wall of the water injection pipe 51 is fixedly connected to the inner wall of the guide cavity 42. The high-pressure water pump 52 is located at the end of the water injection pipe 51 away from the connecting seat 41. The bottom end of the high-pressure water pump 52 is connected to the top end of the atomizing container 3, and the high-pressure water pump 52 is electrically connected to the aforementioned controller. A guide pipe 53 is located on the side of the high-pressure water pump 52 away from the water injection pipe 51. In use, the end of the guide pipe 53 away from the high-pressure water pump 52 is connected to an external water source.

[0085] In a specific application scenario, as shown in the appendix Figure 3As shown, a support box 8 is fixedly installed at the top of the mounting base 1. There is a certain distance between the outer wall of the support box 8 and the inner wall of the aforementioned support frame 2. The top of the support box 8 is open, and a through hole (not shown in the figure) is provided at the bottom. This through hole is located directly above the cooling medium guide hole in the mounting base 1. Several filter plates 9 of different mesh sizes are arranged from bottom to top on the left and right sides of the inner wall of the support box 8. This design allows for the grading and screening of copper powder, separating and collecting copper powder of different particle sizes, thereby obtaining copper powder with a more precise particle size distribution that better meets specific needs. Of course, the sides of the filter plates 9 can be detachably connected to the inner wall of the support box 8. This design facilitates the installation, disassembly, and replacement of the filter plates 9, and allows for adjustment of the mesh size of the filter plates 9 or cleaning and maintenance as needed, thereby improving the flexibility and efficiency of copper powder collection.

[0086] Example 2

In addition to the components in the aforementioned embodiment 1, it also includes a cooling medium circulation mechanism 6. Specifically, the cooling medium circulation mechanism 6 is provided with a liquid extraction end, which passes through the interior of the mounting base 1. The cooling medium circulation mechanism 6 is also provided with a liquid delivery end, which passes through the interior of the atomizing container 3. That is, the liquid delivery end of the cooling medium circulation mechanism 6 is located in the atomizing chamber 31, and the liquid extraction end of the cooling medium circulation mechanism 6 is located in the cooling medium collection chamber 11.

[0088] Further, the cooling medium circulation mechanism 6 includes a first liquid extraction pipe 61, a first reflux pump 62, and a first liquid delivery pipe 63; specifically, the inlet end of the first liquid extraction pipe 61 is located in the cooling medium collection chamber 11; the outlet end of the first liquid extraction pipe 61 is provided with the first reflux pump 62, and a portion of the outer wall of the first liquid extraction pipe 61 is fixedly connected to the inner wall of the cooling medium collection chamber 11; the upper side of the first reflux pump 62 is provided with the first liquid delivery pipe 63, and the outlet end of the first liquid delivery pipe 63 passes through the atomization chamber 31; a cooling medium inlet 38 is opened on the right side of the inner wall of the atomization chamber 31, and the inner wall of the cooling medium inlet 38 is connected to a portion of the outer wall of the first liquid delivery pipe 63, as shown in the attached figure. Figure 3 As shown; normally, the first reflux pump 62 is electrically connected to the aforementioned controller.

[0089] Furthermore, as shown in the appendix Figure 2 and appendix Figure 3 As shown, part of the bottom wall structure of the cooling medium collection chamber 11 is a slope 12, that is, from the side of the cooling medium collection chamber 11 close to the first liquid extraction pipe 61 to the side away from the first liquid extraction pipe 61, the distance between the bottom wall and the top wall of the cooling medium collection chamber 11 gradually decreases. This design can use gravity to allow the cooling medium to be smoothly transported to the atomizing chamber 11 by the cooling medium circulation mechanism 6, which improves the effect of recycling the cooling medium to a certain extent.

[0090] In a specific application scenario, as shown in the appendix Figure 2 and appendix Figure 3 As shown, the cooling medium circulation mechanism 6 also includes a second extraction pipe 64, a second reflux pump 65, and a second delivery pipe 66. The inlet end of the second extraction pipe 64 is located in the cooling medium collection chamber 11, and the outlet end of the second extraction pipe 64 is equipped with the second reflux pump 65. A portion of the outer wall of the second extraction pipe 64 is fixedly connected to the inner wall of the cooling medium collection chamber 11.

Normally, the second reflux pump 65 is electrically connected to the aforementioned controller. At regular intervals, the operator uses the controller to draw the cooling medium from the cooling medium collection chamber 11 to the external cooling medium storage container 67, thereby preventing excessive cooling medium in the cooling medium collection chamber 11 from causing the copper powder preparation to fail.

[0091] This embodiment takes into account one situation, and the specific solution is as follows: A liquid level sensor (not shown in the figure) is installed on the side wall of the cooling medium collection chamber 11. The liquid level sensor is electrically connected to the aforementioned controller. The operator can obtain the current status of the cooling medium in the cooling medium collection chamber 11 in real time through the controller. Several counting sensors (not shown in the figure) are installed on the side of the inner wall of the support frame 8. The number of counting sensors corresponds to the number of filter plates 9. The sensors are electrically connected to the aforementioned controller. The operator can obtain the current amount of copper powder on each filter plate 9 in real time through the controller, and then decide whether to remove the copper powder according to the corresponding situation. To a certain extent, this can prevent the copper powder on the filter plate 9 from overflowing to the top of the mounting base 1.

[0092] This embodiment also considers a scenario, specifically as follows: A vacuum gauge (not shown in the figure) is installed on the inner wall of the atomization chamber 31, and this vacuum gauge is electrically connected to the aforementioned controller; a gas guide branch pipe (not shown in the figure) is inserted through the middle of the gas supply pipe 73, and the inlet end of the gas guide branch pipe is connected to an external nitrogen storage container (not shown in the figure). In use, the vacuum gauge transmits the vacuum level in the atomization chamber 31 to the controller in real time; then, if the operator determines, based on the vacuum level obtained by the controller, that the nitrogen in the atomization chamber 31 alone is insufficient to meet the current requirements for copper powder preparation, the operator replenishes nitrogen to the gas supply pipe 73 through the external nitrogen storage container and the gas guide branch pipe. This is existing technology, and the relevant details will not be elaborated further.
