A copper-zinc alloy powder atomization device with a flow regulation structure

Abstract

The present invention discloses an atomization device for copper-zinc alloy powder with a flow regulation structure. The present invention relates to the technical field of alloy powder production. Due to the change in the flow rate of the alloy thin stream, the extrusion pressure changes. When the change in the extrusion pressure fluctuates unstably, the thin stream becomes intermittent, reducing the uniformity of powder particles during atomization. When the extrusion head of the liquid alloy receives the export pressure, the spring drives the spring to stretch, so that the elastic force generated when the spring stretches cooperates with the extrusion pressure of the liquid alloy. When the extrusion pressure of the liquid alloy decreases, the internal liquid alloy is extruded through the contraction and rebound of the spring. When the extrusion pressure of the liquid alloy increases, the extrusion head slides downward in the inner conduit, increasing the volume of the inner conduit, ensuring the smoothness of the thin stream when the liquid alloy thin stream is extruded, and avoiding fluctuations in the thin stream due to pressure changes during the extrusion of the thin stream, reducing the uniformity of the alloy powder.

Description

Technical Field

[0001] The present invention relates to the technical field of alloy powder production, and specifically to an atomization device for copper-zinc alloy powder with a flow regulation structure. Background Art

[0002] At present, an alloy powder atomization device is a device used to convert molten alloy liquid into fine alloy powder. Common types include gas atomization devices, water atomization devices, and centrifugal atomization devices. Among them, a gas atomization device melts alloy raw materials into a liquid state at high temperature, and then through a specific device, the liquid alloy flows out from a small hole at the bottom of the container to form a liquid stream. At the same time, high-speed and high-pressure gas jets onto the liquid stream at a certain angle from all around, and the powerful impact force breaks the liquid stream into fine droplets. These droplets quickly cool and solidify during flight, and finally form alloy powder.

[0003] When producing alloy powder by impinging a liquid alloy stream with air flow, due to the flow rate of the liquid alloy stream, the extrusion pressure changes. When the change of the extrusion pressure fluctuates unstably, the liquid stream becomes intermittent, reducing the uniformity of powder particles during atomization treatment. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An atomization device for copper-zinc alloy powder with a flow regulation structure, comprising:

[0005] A frame body, on the outer side of which an air pump is fixedly installed. Inside the frame body, a melting furnace is installed, and at the bottom of the melting furnace, a connecting pipe is fixedly installed.

[0006] An atomization mechanism, which is installed inside the frame body. The atomization mechanism is located obliquely below the frame body, and at the bottom of the atomization mechanism, a discharging mechanism is fixedly installed.

[0007] A guiding mechanism, which is used to control the flow of molten metal. The guiding mechanism is installed on the top of the atomization mechanism, and the top of the guiding mechanism is fixedly connected to the bottom end of the connecting pipe.

[0008] Wherein, the flow guiding mechanism comprises an outer cover tube, a fixing ring and a fixing orifice plate are fixedly installed at the bottom of the inner wall of the outer cover tube, the fixing orifice plate is located below the fixing ring, the inner wall of the fixing ring is fixedly connected with an inner conduit, an extrusion head is slidably installed at the bottom of the inner wall of the inner conduit, the inner diameter of the extrusion head gradually decreases from top to bottom, and a slide plate is fixedly installed at the bottom outside the extrusion head, which cooperates with the extrusion head through a spring, and when the liquid alloy thin stream is extruded, the spring is driven to stretch when the extrusion head is subjected to the extrusion pressure of the liquid alloy, so that the elastic force generated by the stretching of the spring cooperates with the extrusion pressure of the liquid alloy, and when the extrusion pressure of the liquid alloy is reduced, the internal liquid alloy is squeezed through the contraction and rebound of the spring, and when the extrusion pressure of the liquid alloy is increased, the extrusion head slides downward in the inner conduit to increase the volume of the inner conduit, thereby ensuring the stability of the thin stream when the liquid alloy thin stream is extruded, and avoiding the occurrence of the thin stream being compressed due to the pressure in the process of leading out the thin stream. The change causes the thin flow to fluctuate, causing the alloy thin flow to fluctuate when impacted by the airflow, thereby reducing the uniformity of the alloy powder. A sliding rod is fixedly installed on the top of the slide board, and the sliding rod is evenly installed along the center position of the extrusion head. The outer side of the sliding rod is slidably adapted to the inner wall of the fixed orifice plate, and a spring is fixedly installed between the fixed orifice plate and the slide board. The upper half of the inner wall of the inner conduit is a conical surface and the inner diameter gradually decreases from top to bottom. Through the coordination of the inner conduit and the inner diameter change of the extrusion head, during the extrusion of the liquid alloy, the air gap between the liquid alloys is squeezed to ensure the stability of the extruded alloy thin flow. At the same time, the inner conduit cooperates with the outer cover tube to form a double-layer structure to improve the thermal insulation effect and avoid the liquid alloy solidifying inside, which causes the extrusion pipeline to be blocked. A spacer ring is fixedly installed on the top of the outer side of the inner conduit, and the spacer ring is fixedly connected to the top of the inner wall of the outer cover tube, and the top of the inner conduit is fixedly connected to the bottom end of the connecting pipe.

[0009] Preferably, the atomization mechanism includes an atomization tank fixedly installed inside the frame body. The inner wall of the atomization tank is fixedly connected with a support frame, and the inner wall of the support frame is fixedly connected with an air duct. The outer side of the air duct is symmetrically provided with air inlet pipes, and the air inlet pipes penetrate through the atomization tank and extend to its outside. A connecting pipe is fixedly connected between the air inlet pipes. The end of the connecting pipe away from the air inlet pipes is fixedly connected with the air outlet end of an air pump through a pipeline. The inner side of the air duct is symmetrically provided with air outlet pipes, and the ends of the air outlet pipes close to each other are inclined downward. Through the air outlet pipes arranged obliquely downward on the inner side of the air duct, in cooperation with the elastic cushion cylinder and the jet head, the gas impacts the alloy fine stream obliquely downward, preventing the alloy fine stream from being washed towards the jet head on the other side by the gas on one side due to the fluctuation of the alloy fine stream during the impact process, which may cause damage to the jet head. At the same time, the obliquely downward impact air flow can drive the alloy powder and cooperate with the discharging mechanism to discharge the alloy powder. The inner wall of the air outlet pipe is slidably connected with a jet head, and an elastic cushion cylinder is fixedly connected to the outer side of the jet head. Through the cooperation of the elastic cushion cylinder and the jet head, during the jetting process, when the air pressure increases, the elastic cushion cylinder is deformed by the jet head, causing the jet heads to approach each other, approaching the alloy fine stream, and cooperating with the increased air pressure to increase the impact on the alloy fine stream and improve the uniformity of the alloy powder. The end of the elastic cushion cylinder away from the jet head is fixedly connected to the outer side of the air outlet pipe. The top of the atomization tank is fixedly installed with an exhaust pipe, and the top of the inner wall of the atomization tank is fixedly connected with a connecting gasket ring. The bottom of the connecting gasket ring is fixedly connected with an inner cover cylinder, and the inner cover cylinder is composed of a column cylinder and a conical cylinder, and the conical cylinder is located below the column cylinder.

[0010] Preferably, the discharging mechanism includes a fixed disk fixedly installed at the bottom of the atomization tank. The top of the fixed disk is fixedly connected with an inner retaining cylinder, and the outer side of the inner retaining cylinder is closely attached to the bottom of the inner wall of the atomization tank. The top of the inner wall of the inner retaining cylinder is fixedly connected with a corrugated ring plate. Through the cooperation of the corrugated ring plate and the screening ring plate, when separating the gas from the alloy powder, the impact force of the gas driving the powder on the screening ring plate is reduced by the blocking of the gas by the corrugated ring plate. At the same time, in cooperation with the corrugations on the inner wall of the corrugated ring plate, the gas between the screening ring plate and the corrugated ring plate fluctuates during flow, preventing the powder from blocking the screening ring plate. The end of the corrugated ring plate away from the inner retaining cylinder is inclined obliquely upward, and the inner wall of the corrugated ring plate is uniformly provided with corrugated grooves and protrusions from top to bottom.

[0011] Preferably, there is a gap between the end of the corrugated ring plate away from the inner stop cylinder and the inner cover cylinder, a hollow groove ring plate is fixedly connected to the bottom of the inner wall of the inner stop cylinder, hollow grooves are evenly provided on the outer side of the hollow groove ring plate, and a screening ring plate is fixedly connected to the outer side of the hollow groove ring plate, and screening holes are evenly provided on the surface of the screening ring plate, a material guide plate is fixedly connected to the bottom of the fixed plate, the top of the material guide plate is a conical surface with a downward depression at the center position, and a guide groove is provided at the center position of the bottom of the material guide plate, and a material guide pipe is fixedly connected to the guide groove at the bottom of the material guide plate.

[0012] The present invention provides a copper-zinc alloy powder atomization device with a flow regulating structure. It has the following beneficial effects:

[0013] 1. The copper-zinc alloy powder atomization equipment with a flow regulating structure drives the spring to stretch when the extrusion head is subjected to the extrusion pressure of the liquid alloy through the spring, so that the elastic force generated by the spring stretching cooperates with the extrusion pressure of the liquid alloy. When the extrusion pressure of the liquid alloy decreases, the internal liquid alloy is squeezed through the contraction and rebound of the spring. When the extrusion pressure of the liquid alloy increases, the extrusion head slides downward in the inner conduit to increase the volume of the inner conduit, thereby ensuring the stability of the liquid alloy thin flow when it is extruded, avoiding fluctuations in the thin flow due to changes in pressure during the process of exporting the thin flow, resulting in fluctuations when the alloy thin flow is impacted by airflow, and reducing the uniformity of the alloy powder.

[0014] 2. The copper-zinc alloy powder atomization equipment with a flow regulating structure, through the coordination of the inner diameter change of the inner conduit and the extrusion head, squeezes the air gap between the liquid alloys during the extrusion of the liquid alloy to ensure the stability of the extruded alloy flow. At the same time, the inner conduit and the outer cover tube cooperate to form a double-layer structure to improve the thermal insulation effect and avoid the liquid alloy solidifying inside, which may cause blockage of the extrusion pipeline.

[0015] 3. The copper-zinc alloy powder atomization equipment with a flow regulating structure uses an outlet pipe arranged obliquely downward on the inner side of the air guide pipe, in conjunction with an elastic cushion tube and a nozzle, to allow the gas to impact the alloy stream obliquely downward, thereby preventing the alloy stream from fluctuating during the impact process, causing the gas on one side to impact the alloy stream toward the nozzle on the other side, thereby damaging the nozzle. At the same time, the airflow impacting obliquely downward can drive the alloy powder and cooperate with the discharging mechanism to discharge the alloy powder.

[0016] Fourth, the copper-zinc alloy powder atomization equipment with a flow regulating structure cooperates with the nozzle through an elastic cushion tube. During the jetting process, when the air pressure increases, the elastic cushion tube is driven to deform through the nozzle head, so that the nozzle heads are close to each other and close to the alloy flow. In combination with the increased air pressure, the impact on the alloy flow is increased, thereby improving the uniformity of the alloy powder.

[0017] V. The atomization equipment for copper-zinc alloy powder with a flow rate adjustment structure, through the cooperation of the corrugated ring plate and the screening ring plate, when separating gas and alloy powder, by blocking the gas with the corrugated ring plate, reduces the impact force of the gas-driven powder on the screening ring plate. At the same time, in cooperation with the corrugations on the inner wall of the corrugated ring plate, the gas between the screening ring plate and the corrugated ring plate fluctuates when flowing, avoiding powder blockage of the screening ring plate.

Detailed Embodiments

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0028] The first embodiment is as follows Figures 1 to 5 shown, the present invention provides a technical solution: a copper-zinc alloy powder atomization device with a flow regulating structure, comprising:

[0029] A frame body 1, on the outer side of which an air pump 5 is fixedly installed, and a melting furnace 6 is installed inside the frame body 1, and a connecting pipe 7 is fixedly installed at the bottom of the melting furnace 6;

[0030] An atomization mechanism 2, which is installed inside the frame body 1, the atomization mechanism 2 is located obliquely below the frame body 1, and a discharge mechanism 4 is fixedly installed at the bottom of the atomization mechanism 2;

[0031] A diversion mechanism 3, which is used to control the flow of molten metal, the diversion mechanism 3 is installed on the top of the atomization mechanism 2, and the top of the diversion mechanism 3 is fixedly connected to the bottom end of the connecting pipe 7;

[0032] Among them, the diversion mechanism 3 includes an outer cover cylinder 31. At the bottom of the inner wall of the outer cover cylinder 31, a fixed collar 35 and a fixed orifice plate 36 are fixedly installed. The fixed orifice plate 36 is located below the fixed collar 35. The inner wall of the fixed collar 35 is fixedly connected to an inner conduit 33. At the bottom of the inner wall of the inner conduit 33, an extrusion head 39 is slidably installed. The inner diameter of the extrusion head 39 gradually decreases from top to bottom. Under pressure, the extrusion head 39 is driven to slide downward. While sliding, the extrusion head 39 drives a spring 38 and a slide bar 37 through a slide plate 34, stretching the spring 38. When the pressure of the molten alloy export decreases, the spring 38 contracts to drive the extrusion head 39 to move upward, compressing the molten alloy in the inner conduit 33. Moreover, at the bottom of the outer side of the extrusion head 39, a slide plate 34 is fixedly installed. At the top of the slide plate 34, a slide bar 37 is fixedly installed. The slide bars 37 are evenly installed along the center position of the extrusion head 39. The outer side of the slide bar 37 is slidably adapted to the inner wall of the fixed orifice plate 36. A spring 38 is fixedly installed between the fixed orifice plate 36 and the slide plate 34. The inner conduit 33 is connected to a communicating pipe 7, enabling the molten alloy to enter the inner conduit 33. Through the change in the inner diameter of the upper half of the inner wall of the inner conduit 33, the molten alloy is extruded, reducing the air gap between the molten alloy, and flowing downward under the action of its own gravity. At the same time, after the molten alloy enters the inside of the extrusion head 39, through the cooperation of the change in the inner diameter of the extrusion head 39 and the change in the inner diameter of the upper half of the inner conduit 33, the molten alloy is extruded again. Finally, under pressure, it is extruded by the extrusion head 39 to form a downward-impacting thin stream of molten alloy. The upper half of the inner wall of the inner conduit 33 is a conical surface and its inner diameter gradually decreases from top to bottom. At the top of the outer side of the inner conduit 33, a spacer ring 32 is fixedly installed. The spacer ring 32 is fixedly connected to the top of the inner wall of the outer cover cylinder 31. The top end of the inner conduit 33 is fixedly connected to the bottom end of the communicating pipe 7.

[0033] Second embodiment. On the basis of the first embodiment, please refer to Figure 6 As shown, the atomization mechanism 2 includes an atomization tank 21. The atomization tank 21 is fixedly installed inside the frame body 1. The inner wall of the atomization tank 21 is fixedly connected to a support frame 24. The inner wall of the support frame 24 is fixedly connected to an air guide pipe 25. By driving an inert gas with an air pump 5, the inert gas is introduced into the inside of the air guide pipe 25 through a pipeline and a connecting pipe 28, and then is introduced into a jet head 27 through the air outlet pipe of the air guide pipe 25 and is exported through the jet heads 27 on both sides. The exported air flow impacts the thin stream of molten alloy, causing the thin stream of alloy to be impacted into fine mist-like alloy under the impact of the air flow that collides on both sides. The air guide pipe 25 is symmetrically provided with air inlet pipes on the outside, and the air inlet pipes penetrate through the atomization tank 21 and extend to its outside. A connecting pipe 28 is fixedly connected between the air inlet pipes. One end of the connecting pipe 28 away from the air inlet pipe is fixedly connected to the air outlet end of the air pump 5 through a pipeline.

[0034] The inner side of the air guide pipe 25 is symmetrically provided with air outlet pipes, and the ends of the air outlet pipes close to each other are inclined downward. The inner wall of the air outlet pipe is slidably connected with a jet head 27. The outer side of the jet head 27 is fixedly connected with an elastic cushion cylinder 26. One end of the elastic cushion cylinder 26 far from the jet head 27 is fixedly connected with the outer side of the air outlet pipe. The top of the atomization tank 21 is fixedly installed with an exhaust pipe 23. During the impact process, the heat of the liquid alloy is absorbed by the low-temperature inert gas, so that the liquid alloy solidifies and becomes fine alloy powder. At the same time, during the atomization process, it is matched with the air outlet pipe of the inner cover cylinder 29 inclined downward, so that the air flow drives the alloy powder to move downward. The air flow and the alloy powder are separated by the feeding mechanism 4. The top of the inner wall of the atomization tank 21 is fixedly connected with a connecting gasket ring 22. The bottom of the connecting gasket ring 22 is fixedly connected with an inner cover cylinder 29. The inner cover cylinder 29 is composed of a column cylinder and a conical cylinder, and the conical cylinder is located below the column cylinder.

[0035] The third embodiment is based on the first and second embodiments. Please refer to Figures 7 to 8 As shown, the feeding mechanism 4 includes a fixed disk 42. The fixed disk 42 is fixedly installed at the bottom of the atomization tank 21. The top of the fixed disk 42 is fixedly connected with an inner retaining cylinder 41. The outer side of the inner retaining cylinder 41 is closely attached to the bottom of the inner wall of the atomization tank 21. The top of the inner wall of the inner retaining cylinder 41 is fixedly connected with a corrugated ring plate 43. During the process of the inert gas driving the alloy powder to move downward together, the gas and the alloy powder are blocked by the guiding disk 44, so that the guiding disk 44 absorbs the impact force of the alloy powder. Subsequently, the inert gas diffuses around. During the diffusion process, the gas passes through the empty slots of the empty slot ring plate 47 and the sieve holes of the sieve material ring plate 46. One end of the corrugated ring plate 43 far from the inner retaining cylinder 41 is inclined upward, and the inner wall of the corrugated ring plate 43 is uniformly provided with corrugated grooves and protrusions from top to bottom.

[0036] There is a gap between one end of the corrugated ring plate 43 far from the inner retaining cylinder 41 and the inner cover cylinder 29. The bottom of the inner wall of the inner retaining cylinder 41 is fixedly connected with an empty slot ring plate 47. The outer side of the empty slot ring plate 47 is uniformly provided with empty slots. The outer side of the empty slot ring plate 47 is fixedly connected with a sieve material ring plate 46. The surface of the sieve material ring plate 46 is uniformly provided with sieve holes. The bottom of the fixed disk 42 is fixedly connected with a guiding disk 44. It is led out through the gap between the sieve material ring plate 46 and the corrugated ring plate 43, and then enters the gap between the inner cover cylinder 29 and the atomization tank 21 through the gap between the corrugated ring plate 43 and the inner cover cylinder 29 and moves upward, and is led out by the exhaust pipe 23. Subsequently, the alloy powder slides down along the inclined surface at the top of the guiding disk 44 and is led out by the guiding pipe 45. The top of the guiding disk 44 is a conical surface sunken downward at the central position, and a guiding groove is opened at the central position of the bottom of the guiding disk 44. A guiding pipe 45 is fixedly connected at the guiding groove at the bottom of the guiding disk 44.

[0037] In use, workers put copper-zinc alloy materials into the melting furnace 6 in the required proportion for heating to melt the materials into a molten alloy solution. Subsequently, the molten materials are introduced into the diversion mechanism 3 through the connecting pipe 7. The diversion mechanism 3 controls the flow and export of the alloy solution, and guides the molten materials into the interior of the atomization mechanism 2 in a thin stream state. At the same time, the required inert gas is introduced into the atomization mechanism 2 through the pipeline by the air pump 5 to impact the thin stream of the molten metal, impact the molten metal into fine droplets, absorb the heat of the alloy melt, solidify it, and let it fall on the top of the discharging mechanism 4. The discharging mechanism 4 separates the gas from the metal powder and exports the metal powder.

[0038] In the diversion mechanism 3, it is connected to the connecting pipe 7 through the inner conduit 33, so that the molten alloy enters the inner conduit 33. Through the change in the inner diameter of the upper half of the inner conduit 33 wall, the molten alloy is squeezed, reducing the air gap between the molten alloys, and flowing downward under the action of its own gravity. At the same time, after the molten alloy melt enters the interior of the extrusion head 39, through the cooperation of the change in the inner diameter of the extrusion head 39 and the change in the inner diameter of the upper half of the inner conduit 33, the molten alloy is squeezed again, and finally extruded by the extrusion head 39 under pressure to form a downward-impacting thin stream of molten alloy. At the same time, the extrusion head 39 is driven to slide downward under pressure. While sliding, the spring 38 and the sliding rod 37 are driven by the sliding plate 34 to stretch the spring 38. When the pressure of the exported molten alloy decreases, the spring 38 contracts to drive the extrusion head 39 to move upward, compressing the molten alloy in the inner conduit 33.

[0039] In the atomization mechanism 2, the air pump 5 drives the inert gas, so that the inert gas is introduced into the interior of the air guide pipe 25 through the pipeline and the connecting pipe 28, and then introduced into the jet head 27 through the air outlet pipe of the air guide pipe 25 and exported through the jet heads 27 on both sides. The exported air flow impacts the thin stream of molten alloy, so that the alloy thin stream is impacted into fine mist-like alloy under the impact of the air flows that collide with each other on both sides. At the same time, during the impact process, the heat of the molten alloy is absorbed by the low-temperature inert gas to solidify the molten alloy into fine alloy powder. At the same time, during the atomization process, it is coordinated with the downwardly inclined air outlet pipe of the inner cover cylinder 29, so that the air flow drives the alloy powder to move downward, and the discharging mechanism 4 separates the air flow from the alloy powder.

[0040] In the discharging mechanism 4, during the process of the inert gas driving the alloy powder to move downward together, the guide plate 44 blocks the gas and the alloy powder, so that the guide plate 44 absorbs the impact force on the alloy powder. Subsequently, the inert gas diffuses around. During the diffusion process, the gas passes through the empty slots of the empty slot ring plate 47 and the sieve holes of the screening ring plate 46, and is discharged through the gap between the screening ring plate 46 and the corrugated ring plate 43. Subsequently, it enters the gap between the inner cover cylinder 29 and the atomization tank 21 through the gap between the corrugated ring plate 43 and the inner cover cylinder 29 and moves upward, and is discharged through the exhaust pipe 23. Subsequently, the alloy powder slides down from the inclined surface at the top of the guide plate 44 and is discharged through the guide pipe 45.

[0041] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
