Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzles, and in particular to an atomizing nozzle for preparing alloys. Background Technology

[0002] With the rapid development of modern industry, the demand for high-performance alloy materials is constantly increasing. Alloy powder, as an important basic material, is widely used in aerospace, automotive manufacturing, and electronics industries. In the preparation process of alloy powder, atomization technology is one of the key steps. As the core component of atomization technology, the performance of the atomizing nozzle directly affects the quality of the alloy powder and production efficiency.

[0003] Traditional atomizing nozzles have some limitations. For example, their fixed nozzle structure makes them unadjustable to different process requirements, resulting in uneven spraying. Furthermore, existing atomizing nozzles often use threaded connections for fixing, which can easily lead to rotation or even falling off, reducing the nozzle's applicability and stability.

[0004] Therefore, it is necessary to propose an atomizing nozzle for alloy preparation to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an atomizing nozzle for alloy preparation, addressing some limitations of traditional atomizing nozzles. For example, the fixed nozzle structure prevents adjustment according to different process requirements, leading to uneven spraying. Furthermore, existing atomizing nozzles often use threaded connections for fixing, which can easily result in rotation or even falling off, reducing the nozzle's applicability and stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an atomizing nozzle for preparing alloys, comprising:

[0007] spray nozzle;

[0008] A nozzle, which is fixed to the bottom end of the nozzle head;

[0009] The nozzle has a first chamber and a second chamber inside, with the second chamber located above the first chamber, and the bottom radius of the first chamber gradually decreasing.

[0010] The first chamber is equipped with a retractable extrusion head, the top of which extends into the second chamber. The top of the extrusion head is provided with an air delivery groove, and the bottom of the air delivery groove is connected to the second chamber.

[0011] A connecting block is provided on one side of the nozzle, and a liquid inlet is opened on one side of the connecting block. The liquid inlet is connected to the interior of the second chamber.

[0012] Preferably, the nozzle has an air inlet at its top, and the air inlet is connected to the interior of the second chamber.

[0013] Preferably, the second chamber is provided with filter cotton, and a lower pressure plate is fixed to the top of the extrusion head;

[0014] A spring is provided on the outside of the extrusion head, and the spring is located between the lower pressure plate and the bottom of the second chamber.

[0015] The second chamber has a sliding groove on its inner side, and a slider is fixed on the outer side of the lower pressure plate;

[0016] The slider is slidably fitted inside the sliding groove.

[0017] Preferably, a delivery pipe is connected between the inlet and the first chamber.

[0018] Preferably, the first chamber and the nozzle are connected.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. When external gas is input into the second chamber, the gas pressure will squeeze the pressure plate down, thereby driving the extrusion head to move downward in the first chamber. Through the extrusion action, the pressure and flow rate of the liquid in the first chamber are changed, and the space inside the first chamber is reduced. At the same time, some gas can enter the interior of the first chamber through the gas delivery groove of the extrusion head and mix with the alloy liquid, increasing the speed and pressure of the alloy liquid ejected from the nozzle.

[0021] 2. After the gas enters the first chamber through the air inlet 4, it can enter the interior of the extrusion head 9 through the air delivery groove 10, thereby creating a certain air pressure around the lower end of the extrusion head 9 to assist in the atomization of the liquid. The filter cotton installed inside the second chamber can filter out impurities in the input gas, ensuring that the alloy mixture liquid entering the nozzle is pure, thereby improving the atomization effect and the quality of the final alloy powder.

[0026] This utility model provides, for example Figures 1-3 An atomizing nozzle for preparing alloys is shown, comprising:

[0027] The nozzle 1 and the nozzle 2 are fixed to the bottom end of the nozzle 1.

[0028] The nozzle 1 has a first chamber 6 and a second chamber 7 inside. The second chamber 7 is located above the first chamber 6. The bottom radius of the first chamber 6 gradually decreases. The nozzle 1 has an air inlet 4 at the top. The air inlet 4 and the second chamber 7 are connected.

[0029] The air inlet 4 is used to introduce gas into the second chamber 7. A connecting block 3 is provided on one side of the nozzle 1, and a liquid inlet 5 is opened on one side of the connecting block 3. The liquid inlet 5 is also connected to the inside of the second chamber 7 and is used to introduce the alloy liquid into the second chamber 7.

[0030] The first chamber 6 is connected to the nozzle 2, which is the final outlet after the alloy liquid and gas are mixed in the first chamber 6.

[0031] The first chamber 6 is equipped with a retractable extrusion head 9. The top of the extrusion head 9 extends into the second chamber 7. An air delivery groove 10 is opened at the top of the extrusion head 9. The bottom of the air delivery groove 10 is connected to the inside of the second chamber 7.

[0032] A connecting block 3 is provided on one side of the nozzle 1, and a liquid inlet 5 is provided on one side of the connecting block 3. The liquid inlet 5 is connected to the interior of the second chamber 7.

[0033] The first chamber 6 is located inside the nozzle 1 at the bottom, with its bottom radius gradually decreasing to form a cone-like structure. This design helps the liquid to accelerate rapidly after entering the first chamber 6 and form a high pressure at the bottom, thereby providing power for the subsequent atomization process.

[0034] The second chamber 7 is equipped with filter cotton 8, and the top of the extrusion head 9 is fixed with a lower pressure plate 12.

[0035] A spring 13 is provided on the outside of the extrusion head 9, and the spring 13 is located between the bottom end of the lower pressure plate 12 and the second chamber 7.

[0036] When external gas is introduced into the second chamber 7, the gas pressure will squeeze the pressure plate 12 down, thereby driving the extrusion head 9 to move downward in the first chamber 6. The extrusion action changes the pressure and flow rate of the liquid in the first chamber 6 and reduces the space inside the first chamber 6. At the same time, some gas can enter the interior of the first chamber 6 through the gas delivery groove 10 of the extrusion head 9 and mix with the alloy liquid, increasing the speed and pressure of the alloy liquid ejected from the nozzle 2.

[0037] The function of spring 13 is to provide elastic support for extrusion head 9, enabling it to extend and retract when subjected to external force, and return to its original position after the external force is removed.

[0038] The second chamber 7 is located above the first chamber 6 and has a relatively large internal space. The filter cotton 8 installed inside the second chamber 7 can filter out impurities in the input gas, ensuring the purity of the alloy mixture entering the nozzle 2, thereby improving the atomization effect and the quality of the final alloy powder.

[0039] The inner side of the second chamber 7 is provided with a sliding groove 15, and a slider 14 is fixed on the outer side of the lower pressure plate 12. The slider 14 is slidably engaged in the sliding groove 15. The sliding groove 15 is used to cooperate with the slider 14 fixed on the outer side of the lower pressure plate 12, so that the lower pressure plate 12 can slide up and down along the sliding groove 15, thereby realizing the extension and retraction movement of the extrusion head 9.

[0040] A liquid inlet 5 and the first chamber 6 are connected by a liquid delivery pipe 11, which is used to transport alloy liquid.
