Technical Field
[0001] The invention relates to the technical field of alloy powder production, in particular to copper-zinc alloy powder atomization equipment with a flow regulating structure. Background Art
[0002] At present, alloy powder atomization equipment is a device used to convert molten alloy liquid into fine alloy powder. Common types include gas atomization equipment, water atomization equipment, and centrifugal atomization equipment. Among them, gas atomization equipment melts the alloy raw material into liquid at high temperature, and then uses a specific device to make the liquid alloy flow out from the small hole at the bottom of the container to form a liquid flow. At the same time, high-speed and high-pressure gas is sprayed from all sides at a certain angle to the liquid flow. The strong impact force breaks the liquid flow into fine droplets. These droplets quickly cool and solidify during the flight process, and finally form alloy powder; When producing alloy powder by impacting liquid alloy thin stream with air flow, the extrusion pressure changes due to the flow rate of the alloy thin stream. When the extrusion pressure changes unstably, the thin stream becomes intermittent, reducing the uniformity of the powder particles during atomization treatment. Summary of the invention

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.

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, and the inner wall of the outlet pipe is slidably connected with a nozzle, and the outer side of the nozzle is fixedly connected with an elastic cushion tube, which cooperates with the nozzle head through the elastic cushion tube.

The end of the elastic cushion tube away from the nozzle head is fixedly connected to the outer side of the outlet pipe, and an exhaust pipe is fixedly installed on the top of the atomizer tank, and a connecting gasket is fixedly connected to the top of the inner wall of the atomizer tank, and the bottom of the connecting gasket is fixedly connected to an inner cover tube, and the inner cover tube is composed of a column tube and a conical tube, and the conical tube is located below the column tube.
[0005] Preferably, the discharging mechanism includes a fixed plate, which is fixedly mounted on the bottom of the atomizer tank, and the top of the fixed plate is fixedly connected to an inner stopper, the outer side of the inner stopper is tightly fitted with the bottom of the inner wall of the atomizer tank, and the top of the inner wall of the inner stopper is fixedly connected to a corrugated ring plate, which cooperates with the sieve ring plate to block the gas through the corrugated ring plate when separating the gas and the alloy powder, thereby reducing the impact force of the gas-driven powder on the sieve ring plate, and at the same time, cooperate with the corrugations of the inner wall of the corrugated ring plate to make the gas between the sieve ring plate and the corrugated ring plate fluctuate when flowing, so as to avoid the sieve ring plate being blocked by the powder, and the end of the corrugated ring plate away from the inner stopper is inclined upward, and the inner wall of the corrugated ring plate is evenly provided with corrugated grooves and protrusions from top to bottom.

[0007] The present invention provides a copper-zinc alloy powder atomization device with a flow regulating structure. It has the following beneficial effects: 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 5. The copper-zinc alloy powder atomization equipment with a flow regulating structure cooperates with the sieve ring plate through the corrugated ring plate. When separating the gas and the alloy powder, the corrugated ring plate blocks the gas, thereby reducing the impact force of the gas-driven powder on the sieve ring plate. At the same time, the corrugations on the inner wall of the corrugated ring plate cause the gas between the sieve ring plates to fluctuate during flow, thereby preventing the powder from clogging the sieve ring plate.

The flow guiding mechanism 3 is installed on the top of the atomizing mechanism 2, and the top of the flow guiding mechanism 3 is fixedly connected to the bottom end of the connecting pipe 7; The guide mechanism 3 includes an outer cover tube 31, a fixing ring 35 and a fixing orifice plate 36 are fixedly installed at the bottom of the inner wall of the outer cover tube 31, and the fixing orifice plate 36 is located below the fixing ring 35. The inner wall of the fixing ring 35 is fixedly connected with the inner guide tube 33, and the bottom of the inner wall of the inner guide tube 33 is slidably installed with an extrusion head 39. 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, and the spring 38 and the slide bar 37 are driven by the slide plate 34 while sliding to stretch the spring 38. When the pressure of the liquid alloy is reduced, the extrusion head 39 is driven to move upward by the contraction of the spring 38 to compress the liquid alloy in the inner guide tube 33, and the slide plate 34 is fixedly installed at the bottom of the outer side of the extrusion head 39, and the slide bar 37 is fixedly installed on the top of the slide plate 34. The slide bar 37 is evenly installed along the center position of the extrusion head 39, and the outer side of the slide bar 37 is slidably adapted to the inner wall of the fixing orifice plate 36. A spring 38 is fixedly installed between the orifice plate 36 and the slide plate 34, which is connected to the connecting pipe 7 through the inner conduit 33, so that the alloy in the molten state enters the inner conduit 33. The inner diameter of the upper part of the inner wall of the inner conduit 33 changes, so that the liquid alloys are squeezed, the air gap between the liquid alloys is reduced, and the liquid alloys flow downward under the action of their own gravity. At the same time, after the liquid alloy melt enters the interior of the extrusion head 39, the inner diameter change of the extrusion head 39 cooperates with the inner diameter change of the upper part of the inner conduit 33 to squeeze the liquid alloy again. Finally, the extrusion head 39 extrude under pressure to form a thin stream of liquid alloy that impacts downward. The upper part of the inner wall of the inner conduit 33 is a conical surface and the inner diameter gradually decreases from top to bottom. A spacer ring 32 is fixedly installed on the top of the outer side of the inner conduit 33. The spacer ring 32 is fixedly connected to the top of the inner wall of the outer cover tube 31, and the top of the inner conduit 33 is fixedly connected to the bottom end of the connecting pipe 7.
[0016] The second embodiment is based on the first embodiment. Figure 6As shown, the atomization mechanism 2 includes an atomization tank 21, which is fixedly installed inside the frame 1, and the inner wall of the atomization tank 21 is fixedly connected to a support frame 24, and the inner wall of the support frame 24 is fixedly connected to an air guide pipe 25. The inert gas is driven by the air pump 5, so that the inert gas is introduced into the interior of the air guide pipe 25 through a pipeline and a connecting pipe 28, and then introduced into the nozzle head 27 through the air outlet pipe of the air guide pipe 25, and is exported through the nozzle heads 27 on both sides. The exported airflow impacts the liquid alloy flow, so that the alloy flow is impacted into a fine mist-like alloy under the impact of the airflows on both sides. The outer side of the air guide pipe 25 is symmetrically provided with an air inlet pipe, and the air inlet pipe passes through the atomization tank 21 and extends to the outside thereof. A connecting pipe 28 is fixedly connected between the air inlet pipes, and the connecting pipe 28 is fixedly connected to the air outlet end of the air pump 5 through a pipeline at one end away from the air inlet pipe.
[0017] An air outlet pipe is symmetrically arranged on the inner side of the air guide pipe 25, and the ends of the air outlet pipes close to each other are inclined downward, and the inner wall of the air outlet pipe is slidably connected to a nozzle 27, and an elastic cushion tube 26 is fixedly connected to the outer side of the nozzle head 27, and the end of the elastic cushion tube 26 away from the nozzle head 27 is fixedly connected to the outer side of the air outlet pipe, and an exhaust pipe 23 is fixedly installed on the top of the atomizing tank 21. During the impact process, the heat of the liquid alloy is absorbed by the low-temperature inert gas, so that the liquid alloy is solidified and turned into fine alloy powder. At the same time, during the atomization process, the air outlet pipe inclined downward is cooperated by the inner cover tube 29, so that the airflow drives the alloy powder to move downward, and the airflow and the alloy powder are separated by the discharging mechanism 4, and the top of the inner wall of the atomizing tank 21 is fixedly connected to a connecting gasket ring 22, and the bottom of the connecting gasket ring 22 is fixedly connected to an inner cover tube 29, and the inner cover tube 29 is composed of a column tube and a conical tube, and the conical tube is located below the column tube.
[0018] The third embodiment is based on the first and second embodiments. Figures 7 and 8 As shown, the discharging mechanism 4 includes a fixed plate 42, which is fixedly installed at the bottom of the atomizing tank 21, and the top of the fixed plate 42 is fixedly connected with an inner baffle tube 41, the outer side of the inner baffle tube 41 is tightly fitted with the bottom of the inner wall of the atomizing tank 21, and the top of the inner wall of the inner baffle tube 41 is fixedly connected with a corrugated ring plate 43. In the process of the inert gas driving the alloy powder to move downward together, the gas and the alloy powder are blocked by the guide plate 44, so that the impact force of the alloy powder on the guide plate 44 is absorbed, and then the inert gas diffuses to the surroundings. In the process of diffusion, the gas passes through the empty grooves of the empty groove ring plate 47 and the sieve holes of the sieve ring plate 46. The end of the corrugated ring plate 43 away from the inner baffle tube 41 is inclined upward, and the inner wall of the corrugated ring plate 43 is evenly provided with corrugated grooves and protrusions from top to bottom.
[0019] There is a gap between the end of the corrugated ring plate 43 away from the inner stop tube 41 and the inner cover tube 29, and a hollow groove ring plate 47 is fixedly connected to the bottom of the inner wall of the inner stop tube 41, and hollow grooves are evenly provided on the outer side of the hollow groove ring plate 47, and a sieve ring plate 46 is fixedly connected to the outer side of the hollow groove ring plate 47, and sieve holes are evenly provided on the surface of the sieve ring plate 46. A guide plate 44 is fixedly connected to the bottom of the fixed plate 42, and the powder is guided out through the gap between the sieve ring plate 46 and the corrugated ring plate 43, and then enters the gap between the inner cover tube 29 and the atomizing tank 21 through the gap between the corrugated ring plate 43 and the inner cover tube 29, moves upward, and is guided out by the exhaust pipe 23, and then the alloy powder slides on the inclined surface at the top of the guide plate 44 and is guided out by the guide pipe 45. The top of the guide plate 44 is a conical surface with a downward depression in the center position, and a guide groove is provided at the center position of the bottom of the guide plate 44, and a guide pipe 45 is fixedly connected to the guide groove at the bottom of the guide plate 44.
[0020] When in use, workers put the copper-zinc alloy material into the smelting furnace 6 according to the required proportion and heat it to melt the material and turn it into a molten alloy solution. Then, the molten material is introduced into the guide mechanism 3 through the connecting pipe 7. The flow outlet of the alloy solution is controlled by the guide mechanism 3, and the molten material is introduced into the interior of the atomizing mechanism 2 in a thin stream state through the guide mechanism 3. At the same time, the required inert gas is introduced into the atomizing mechanism 2 through the pipeline through the air pump 5 to impact the thin stream of the molten metal, impact the metal liquid into fine droplets, absorb the heat of the molten alloy, solidify it, and fall on the top of the discharging mechanism 4. The gas is separated from the metal powder by the discharging mechanism 4, and the metal powder is discharged.
[0021] In the flow guiding mechanism 3, the inner conduit 33 is connected to the connecting pipe 7 to allow the molten alloy to enter the inner conduit 33. The inner diameter of the upper part of the inner wall of the inner conduit 33 changes, so that the liquid alloys are squeezed to reduce the air gap between the liquid alloys and flow downward under the action of their own gravity. At the same time, after the liquid alloy melt enters the interior of the extrusion head 39, the inner diameter change of the extrusion head 39 cooperates with the inner diameter change of the upper part of the inner conduit 33 to squeeze the liquid alloy again. Finally, the extrusion head 39 extrude under pressure to form a thin stream of liquid alloy that impacts downward. At the same time, the extrusion head 39 is driven to slide downward under pressure. While sliding, the spring 38 and the slide bar 37 are driven by the slide plate 34 to stretch the spring 38. When the liquid alloy outlet pressure decreases, the spring 38 contracts and drives the extrusion head 39 to move upward to compress the liquid alloy in the inner conduit 33.
[0022] In the atomizing mechanism 2, the inert gas is driven by the air pump 5, so that the inert gas is introduced into the interior of the air guide tube 25 through the pipeline and the connecting tube 28, and then introduced into the nozzle 27 through the outlet pipe of the air guide tube 25, and discharged through the nozzles 27 on both sides. The discharged airflow impacts the liquid alloy flow, so that the alloy flow is impacted into a fine mist alloy under the impact of the airflows on both sides. At the same time, during the impact process, the heat of the liquid alloy is absorbed by the low-temperature inert gas, so that the liquid alloy is solidified and turned into fine alloy powder. At the same time, during the atomization process, the air outlet pipe inclined downwardly cooperates with the inner cover tube 29, so that the airflow drives the alloy powder to move downward, and the airflow and the alloy powder are separated by the discharging mechanism 4.
[0023] In the discharging mechanism 4, when the inert gas drives the alloy powder to move downward, the gas and the alloy powder are blocked by the guide plate 44, so that the impact force of the alloy powder on the guide plate 44 is absorbed, and then the inert gas diffuses to the surroundings. In the process of diffusion, the gas passes through the empty grooves of the empty groove ring plate 47 and the sieve holes of the sieve ring plate 46, and is discharged through the gap between the sieve ring plate 46 and the corrugated ring plate 43, and then enters the gap between the inner cover tube 29 and the atomizing tank 21 through the gap between the corrugated ring plate 43 and the inner cover tube 29, and moves upward, and is discharged by the exhaust pipe 23. Then, the alloy powder slides down the inclined surface at the top of the guide plate 44 and is discharged by the guide pipe 45.
