Abstract
Description
Technical Field
[0001] This invention relates to the field of water atomization powder production technology, specifically a processing device for processing silver-coated copper powder. Background Technology
[0002] Silver-coated copper powder possesses excellent electrical conductivity and is widely used in additive manufacturing and other applications. In actual silver-coated copper powder manufacturing, the copper material must first be powdered. This typically involves heating the copper into a molten state, then using an atomizing nozzle of a metal atomizing powder-making device to impact and pulverize the copper. The tundish in this powder-making device is responsible for heating and maintaining the temperature of the molten copper and discharging it. Currently, tundishes used in silver-coated copper powder processing often use a direct pouring method for molten copper discharge, resulting in rapid oxidation of the copper within the tundish and the generation of a large amount of oxide slag. It is neither convenient for slag removal nor can it achieve gas protection without affecting copper liquid discharge and powder making. Furthermore, due to the low liquid level, the discharge speed of the copper liquid tail material is too slow, resulting in the copper liquid cooling too quickly and adhering to the inner wall of the guide pipe, affecting the water atomization powder making effect. At the same time, in order to contact the copper liquid earlier and reduce the temperature drop when the copper liquid is discharged, the traditional water atomizing nozzle is usually close to the end of the guide pipe. When the nozzle is blocked, it is very easy for the atomized water to be sprayed directly into the guide pipe, causing the guide pipe to shrink and break due to cold, and directly affecting the atomized particle size of the copper liquid.
[0003] Therefore, we propose a processing device for processing silver-coated copper powder. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] This invention employs a gas-shielding device that uses pneumatic purging in conjunction with a slag-collecting shell to isolate oxide impurities or floating impurities in molten copper. This effectively prevents the upper layer of slag from clogging the guide pipe during actual copper atomization, which would also affect the water atomization particle size and the quality of the finished copper powder. The structure utilizes a baffle bowl to prevent the molten copper discharged from the inlet pipe from directly impacting floating impurities into the guide pipe. The structure is simple and reasonable, effectively reducing the slag content of the molten copper inside the tundish heating elements. The gas-shielding device can provide inert gas protection by supplying helium, further reducing the slag content in the inlet pipe. This system reduces the oxidation level of the molten copper, decreases the amount of oxide slag, and lowers the overall oxide slag content. Simultaneously, it works in conjunction with the inlet control system to regulate the inlet flow. During normal inlet flow, the heating sleeve can be opened without affecting venting. When copper tailings need to be discharged through the guide pipe, the heating sleeve can be closed to utilize air pressure and accelerate the discharge speed. This prevents the copper tailings from adhering to the inner hole of the guide pipe and dripping, as the discharge pressure decreases with the drop in copper tailings level, leading to wall adhesion and dripping. In this case, the copper temperature drops, affecting the quality of water atomization powder production.
[0019] The nozzle protective sleeve can be used to protect the guide pipe and prevent water from being sprayed directly onto the guide pipe due to blockage or deformation of the nozzles in the water atomizing powder maker. This would cause a sudden drop in the temperature of the guide pipe and lead to problems such as cold shrinkage cracks. The protective sleeve can be used to shield and protect the pipe. The protective sleeve, which can rotate at all angles, can be used in conjunction with a micro switch for detection and control prompts, so that staff can be informed in time and carry out maintenance work in a timely manner.

[0032] Example 1: Please refer to Figures 1 to 10 As shown:
[0033] This invention provides a technical solution: a processing device for processing silver-coated copper powder, comprising an intermediate ladle heating element 1, with a slag collecting element 2 installed inside the intermediate ladle heating element 1, characterized in that: the slag collecting element 2 is used to isolate waste slag; a gas-holding device 3 is installed on the intermediate ladle heating element 1; the gas-holding device 3 is used to fill with inert gas for oxidation resistance; a liquid inlet control element 4 is installed on the gas-holding device 3; the liquid inlet control element 4 is used to seal the intermediate ladle heating element 1; a nozzle protection element 5 is installed at the bottom of the intermediate ladle heating element 1; the nozzle protection element 5 is used to prevent the intermediate ladle heating element 1 from shrinking due to cold; the intermediate ladle heating element 1 includes: a mounting shell 101 and an indicator light 1011, the mounting shell 101 has a flange at the bottom; the mounting shell 101 has threads at the top; the inner side of the flange at the bottom of the mounting shell 101 is an arc-shaped spherical surface; the indicator light 1011 is fixedly installed on the side of the flange at the bottom of the mounting shell 101.
[0034] The intermediate ladle heating element 1 further includes: a heating inner liner 102, a guide pipe 103, and a stop cup 104. The heating inner liner 102 is fixedly installed inside the mounting shell 101. An electric heating wire is provided inside the heating inner liner 102. The heating inner liner 102 is used to heat the molten copper. The guide pipe 103 is fixedly installed at the bottom of the heating inner liner 102, and the guide pipe 103 is fixedly installed at the bottom of the mounting shell 101. The stop cup 104 is fixedly installed on the inner side of the heating inner liner 102, and the bottom of the stop cup 104 is provided with a ring of through holes. The stop cup 104 is used to reduce the impact of the molten copper. The slag collecting element 2 includes: a slag collecting shell 201 and a furnace hook hole 2011. The slag collecting shell 201 is sleeved inside the heating inner liner 102. The slag collecting shell 201 is located in... The inner side of the mounting shell 101 is sloping, and the bottom of the slag collection shell 201 has a through groove. Two furnace hook holes 2011 are provided on the slag collection shell 201. A through hole is provided in the middle of the slag collection shell 201. The gas-proof device 3 includes: a gas-proof cover 301, a sliding shaft 302, an air inlet pipe 303, an air jet ring 304, and a hollow floating shell 3041. The gas-proof cover 301 has a handle. The gas-proof cover 301 is threaded onto the mounting shell 101. The sliding shaft 302 is slidably inserted into the gas-proof cover 301, and the sliding shaft 302 has graduation lines. The air inlet pipe 303 is slidably inserted into the gas-proof cover 301. A helium pump is connected to the external air inlet pipe 303. The bottoms of the sliding shaft 302 and the air inlet pipe 303 are fixed. A jet ring 304 is installed, and the jet ring 304 and the slag collection shell 201 are concentric. An inclined air outlet groove is provided on the outer side of the jet ring 304. The jet ring 304 is connected to the air inlet pipe 303. The air outlet groove on the jet ring 304 is used to sweep away floating slag. A ring of hollow floating shells 3041 is fixedly installed at the bottom of the jet ring 304. Each ring of hollow floating shells 3041 has a hollow structure. Each ring of hollow floating shells 3041 is used to float on the surface of the copper liquid. The gas-holding device 3, through pneumatic sweeping, in conjunction with the slag collection shell 201, can be used to isolate oxide impurities or floating impurities in the copper liquid. This effectively prevents the upper layer of floating slag from clogging the guide pipe 103 during actual copper liquid atomization discharge, and also avoids affecting... The particle size of the atomized copper powder affects the quality of the finished product. This structure uses a stop bowl 104 to prevent the copper liquid discharged from the inlet pipe 401 from directly impacting floating impurities to the guide pipe 103. The structure is simple and reasonable, which can effectively reduce the slag content of the copper liquid inside the tundish heating element 1. The floating air jet ring 304 is easy to adapt to the liquid level and is more suitable for continuous liquid feeding. Helium is supplied through the helium pump connected to the air inlet pipe 303 and air is sprayed from the inclined air outlet groove on the air jet ring 304. This facilitates the blowing of floating slag or oxide slag outward by wind power and collects it in the inner ring above the slag collection shell 201. Subsequently, when the liquid level in the heating inner liner 102 drops or is emptied, the slag or oxide impurities can be isolated by the slag collection shell 201.
[0035] The gas-proof device 3 further includes: a stop post 305, which is fixedly installed on the bottom of the gas-proof cover 301 by a bracket, and the top of the stop post 305 is a conical structure; the stop post 305 is located in the middle of the jet ring 304; the gas-proof device 3 further includes: a heating sleeve 306, which is fixedly installed on the gas-proof cover 301, and an electric heating wire is provided on the inner side of the heating sleeve 306; the top of the heating sleeve 306 is a conical inclined structure; a ring of through holes is opened on the heating sleeve 306; the liquid inlet control component 4 includes: a liquid inlet pipe 401, a liquid inlet hopper 4011, and a liquid inlet connecting rod 402, with the liquid inlet hopper 4011 fixedly installed on the liquid inlet pipe 401; the liquid inlet pipe 401 is slidably sleeved on the heating sleeve 306. The inlet pipe 401 is located above the stop post 305; two inlet connecting rods 402 are fixedly installed on the inlet hopper 4011; the inlet pipe 401 is used to discharge copper liquid; the inlet control component 4 also includes: an electromagnet 403, a sleeve shell 404, and a support spring 405, with an electromagnet 403 fixedly installed on each of the two inlet connecting rods 402; two sleeve shells 404 are fixedly installed on the gas cover 301, and an electromagnet 403 is slidably inserted into each of the two sleeve shells 404; support springs 405 are respectively provided on the outer side of the two electromagnets 403, and one end of each support spring 405 is fixedly connected to the bottom of the two inlet connecting rods 402, and the other end of each support spring 405 is fixedly connected to the sleeve shell 402. On the 04th, the gas-insulating device 3 can also be used to provide inert gas protection by supplying helium, reducing the oxidation level of the copper liquid discharged from the inlet pipe 401 and reducing the amount of oxide slag. Simultaneously, in conjunction with the inlet control device 4, the inlet can be controlled. During normal inlet pipe 401 inlet flow, the heating sleeve 306 can be opened without affecting venting. Conversely, when copper liquid tailings need to be discharged through the guide pipe 103, the heating sleeve 306 can be closed to utilize air pressure and accelerate the tailings discharge speed. This prevents copper liquid from adhering to the inner hole of the guide pipe 103 and dripping due to the decrease in discharge pressure and speed as the copper liquid level drops. At this time, the copper liquid temperature... Lowering the pressure will affect the quality of water atomization powder production, but the structure is simple to control. When the copper liquid is discharged in the early stage of the inlet pipe 401, the helium gas sprayed by the jet ring 304 can overflow from a ring of holes on the heating sleeve 306. However, after the copper liquid is poured out of the copper smelting furnace, when the last tail material in the heating inner liner 102 is discharged, the electromagnet 403 can be controlled to magnetically attract the sleeve 404 and compress the support spring 405. At this time, the bottom of the inlet hopper 4011 will stop the heating sleeve 306, and the bottom of the inlet pipe 401 will also be sealed against the stop post 305. At this time, the gas pressure sprayed by the jet ring 304 can only be discharged from the guide pipe 103, and can maintain rapid discharge, avoiding continuous dripping of droplets for a long time. The structure is simple and reliable to control.
[0036] In Example 2, based on Example 1, the nozzle protective component 5 includes: a protective sleeve 501, a pressing ring 502, and a micro switch 503. The outer side of the protective sleeve 501 has a spherical arc surface structure. The protective sleeve 501 is fitted onto the bottom of the mounting housing 101. The pressing ring 502 is fixedly installed on the protective sleeve 501. A ring of micro switches 503 is fixedly installed on the bottom of the mounting housing 101, and the ring of micro switches 503 is located above the pressing ring 502. The protective sleeve 501 is located outside the guide tube 103. The ring of micro switches 503 is electrically connected to the indicator light 1011. The nozzle protective component 5 includes: an impact protective ring 504, which... The protective ring 504 is fixedly installed at the bottom of the protective sleeve 501. The impact protective ring 504 is located above the ring of nozzles of the water atomizing powder maker. The nozzle protection component 5 can be used to protect the guide pipe 103 and prevent water from being sprayed directly onto the guide pipe 103 due to blockage or deformation of the ring of nozzles of the water atomizing powder maker. This would cause the temperature of the guide pipe 103 to drop suddenly and cause problems such as cold shrinkage cracks. The protective sleeve 501 provides shielding protection. At the same time, the protective sleeve 501, which can rotate at all angles, can be used in conjunction with the micro switch 503 for detection and control prompts, so that the staff can be informed in time and carry out maintenance work in a timely manner.
[0037] The working principle of this embodiment is as follows: First, the flange at the bottom of the mounting shell 101 is bolted onto the metal atomizing powder maker. The heating inner liner 102 and the electric heating wires in the heating sleeve 306 are then turned on for heating. At this time, molten copper can be added to the inlet hopper 4011. The molten copper discharged from the inlet pipe 401 flows into the stop bowl 104, which then stops the molten copper from overflowing through the through-hole at the bottom of the stop bowl 104 and from above it. As a large amount of molten copper is discharged from the inlet pipe 401, the discharge rate of the guide pipe 103 is relatively low. Slowly, at this moment, the copper liquid level inside the heating inner liner 102 rises rapidly. As the copper liquid submerges the slag collecting shell 201, because the bottom of the slag collecting shell 201 has a sloping structure, it can prevent slag or dross from being blocked at the bottom of the slag collecting shell 201, thus not affecting the slag's floating. Together with the hollow floating shell 3041, it floats on the surface of the copper liquid. At this time, the height of the jet ring 304 can be observed through the scale line on the sliding shaft 302. Helium is supplied through the helium pump connected to the air inlet pipe 303, and jets are emitted from the sloping air outlet groove on the jet ring 304, facilitating the passage of floating slag or oxide dross. The wind blows outwards and gathers on the inner ring above the slag collection shell 201. Subsequently, when the liquid level in the heating inner liner 102 drops or is emptied, the slag collection shell 201 can isolate slag or oxide impurities. The molten copper discharged from the guide pipe 103 can be atomized and pulverized by water droplets sprayed from a ring of nozzles in the water atomizer. During the initial discharge of molten copper from the inlet pipe 401, helium gas ejected from the jet ring 304 can be discharged through a ring of through holes on the heating sleeve 306. However, after the molten copper in the copper smelting furnace has been completely poured out, the final tailings in the heating inner liner 102 can be controlled... The electromagnet 403 magnetically attaches to the housing 404 and compresses the support spring 405. At this time, the bottom of the liquid inlet hopper 4011 will stop the heating sleeve 306, and the bottom of the liquid inlet pipe 401 will also be sealed against the stop post 305. At this time, the air pressure ejected by the jet ring 304 can only be discharged from the guide pipe 103, and can maintain rapid discharge to avoid continuous dripping of liquid droplets for a long time. The structure control is simple and reliable. When it is necessary to clean the slag collection shell 201, manually rotate and remove the gas cover 301, insert the furnace hook into the two furnace hook holes 2011, and then lift out the slag collection shell 201.
[0038] If the nozzle of the water atomizing powder maker is blocked or other factors, causing the sprayed water column to impact the impact protection ring 504, it can be stopped by the protective sleeve 501. At the same time, once the protective sleeve 501 is impacted, it will tilt and squeeze the micro switch 503 on the opposite side. At this time, the indicator light 1011 will light up to indicate that the staff should check it in time.
