Description

Technical Field

[0001] The present application relates to the technical fields of additive manufacturing and powder metallurgy, and in particular to an electrostatic suppression device for an EIGA argon circulation system based on dynamic humidity compensation. Background Art

[0002] In the EIGA process of preparing metal powder for 3D printing, recycling atomizing gas (typically argon or nitrogen) can significantly reduce production costs. However, after repeated use, the recycled gas gradually loses moisture, becoming overly dry. This dry atomizing gas causes electrostatic adsorption between metal powder particles, forming agglomerates. This affects powder flowability and spreading uniformity, thereby reducing the density and mechanical properties of the 3D printed part. Furthermore, agglomerated powder can lead to an increase in satellite particles, disrupting the optimized particle size distribution and impacting the stability of the SLM or EBM process.

[0003] Traditional humidification devices generally choose to install an atomizing nozzle on the circulating gas pipeline to atomize deionized water to humidify the gas in the circulating gas pipeline. However, traditional humidification devices can easily lead to uneven humidification if they continue to humidify for a long time, which may cause local over-humidification or insufficient humidification. Summary of the Invention

[0005] The present application provides an EIGA argon circulation system static suppression device based on dynamic humidity compensation, which adopts the following technical solutions: An electrostatic suppression device of an EIGA argon circulation system based on dynamic humidity compensation includes a circulating gas pipeline, a first connecting pipe, a second connecting pipe and an atomizing assembly, wherein the first connecting pipe and the second connecting pipe are arranged on one side of the circulating gas pipeline, the first connecting pipe is provided with an air inlet part, and the second connecting pipe is provided with a water supply part, the atomizing assembly is arranged between the first connecting pipe and the second connecting pipe, the atomizing assembly is connected to both the first connecting pipe and the second connecting pipe, one end of the atomizing assembly away from the first connecting pipe and the second connecting pipe is connected to the circulating gas pipeline, both ends of the circulating gas pipeline are connected to a metal powder printing device, and the atomized gas enters the metal powder printing device via the circulating gas pipeline, the atomizing assembly includes an adjusting part and an atomizing nozzle, both ends of the adjusting part are respectively connected to the first connecting pipe and the second connecting pipe, one end of the atomizing nozzle is connected to the adjusting part, and the other end is connected to the circulating gas pipeline, and the adjusting part is used to adjust the atomizing spray amount.

[0006] By adopting the above technical solution, argon gas enters the atomizing assembly through the first connecting pipe, and deionized water enters the atomizing assembly through the second connecting pipe. Argon gas and deionized water are sprayed out from the atomizing nozzle through the regulating member. The regulating member can adjust the spray volume in real time according to the change of air pressure. The spray humidifies the gas in the circulating gas pipeline, improves the humidity stability of the atomizing gas, optimizes the powder performance, and reduces the possibility of the atomizing gas causing electrostatic adsorption between metal powder particles.

[0008] By adopting the above technical solution, when the air pressure increases, the regulating block approaches the atomizing nozzle, the distance between the regulating block and the regulating slope is shortened, and the spray volume is reduced. When the air pressure decreases, the regulating block moves away from the atomizing nozzle, the distance between the regulating block and the regulating slope is increased, and the spray volume is increased, so that the spray volume entering the circulating gas pipeline can be adaptively changed in real time with the gas pressure.

[0015] Optionally, the guide strips are arranged in an "n" shape.

[0016] By adopting the above technical solution, the “n”-shaped guide groove allows the gas and deionized water entering the atomizing nozzle to maintain a moderate flow rate.

The sterilization component is provided in the water tank and is used to sterilize the deionized water in the water tank. The second filter is provided at one end of the second connecting pipe located in the water tank and is used to filter impurities in the deionized water.

[0022] By adopting the above technical solution, the sterilizing element sterilizes the deionized water in the water tank, and after sterilization, the deionized water enters the second connecting pipe through the second filter, thereby improving the purity of the deionized water.

[0023] Optionally, a dew point detector and a control component are provided outside the circulating gas pipeline, the dew point detector and the control component are electrically connected, and the dew point detector is used to monitor the dew point of the gas outside the circulating gas pipeline.

[0041] The implementation principle of the electrostatic suppression device of the EIGA argon circulation system based on dynamic humidity compensation in the embodiment of the present application is as follows: argon gas enters the first connecting pipe 2, passes through the first filter 51, the pressure reducing valve 52 and the solenoid valve 53 in sequence, and enters the first installation pipe 42. At the same time, deionized water passes through the second filter 64 and the second connecting pipe 3 and enters the first installation pipe 42. The gas pressure drives the regulating block 43 to approach or move away from the atomizing nozzle 46, thereby adjusting the gap between the regulating block 43 and the atomizing nozzle 46, and controlling the amount and pressure of deionized water entering the atomizing nozzle 46. The solenoid valve 53 and the pressure reducing valve 52 can cooperate to control the gas pressure of the argon gas entering the first installation pipe 42. Through the control component 12, the dew point detector 11, the solenoid valve 53 and the pressure reducing valve 52, the spray in the circulating gas pipeline 1 is controlled in real time, thereby improving the real-time performance of the spray and adapting the spray size, thereby improving the humidity stability of the atomizing gas and optimizing the powder performance.
