Description

Technical Field

[0001] This utility model relates to the field of metal powder recovery devices, and in particular to a metal powder inert gas protected recovery device. Background Technology

[0002] Metal powders are widely used in metal processing, 3D printing, and other fields. However, the recycling of metal powders faces many challenges. On the one hand, many metal powders are chemically reactive and easily undergo oxidation reactions with oxygen in the air, leading to powder deterioration, affecting their subsequent performance, and wasting resources.

[0003] Traditional recycling devices often lack effective filtration and separation structures, causing powder to accumulate during the recycling process. This not only affects recycling efficiency but also makes it difficult to effectively separate powders of different particle sizes, thus reducing the quality of the recycled powder.

[0004] Therefore, it is necessary to propose a metal powder inert gas protection and recovery device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a metal powder inert gas protection recovery device to solve the problem that traditional recovery devices often lack effective filtration and separation structures, and powder tends to accumulate during the recovery process, which not only affects the recovery efficiency but also makes it difficult to effectively separate powders of different particle sizes, thus reducing the quality of the recovered powder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal powder inert gas protection and recovery device, comprising a recovery chamber and a gas storage tank, wherein the recovery chamber and the gas storage tank are circulatedly connected by a pipeline; The top of the recovery chamber is detachably connected to a top cover, the top of the top cover is provided with a powder inlet, the bottom of the top cover is fixed with a filter inner cylinder, and an outer cylinder is provided on the outside of the filter inner cylinder; The bottom end of the inner cylinder of the filter screen is threadedly connected to a bottom cover. A column is fixed to the top of the bottom cover. Multiple conical covers are arranged along the height direction of the column. The tips of the conical covers are arranged upwards, and the bottom end of the powder inlet is connected to the inner cylinder of the filter screen. A gap is left between the outer side of the conical cover and the inner wall of the inner cylinder of the filter screen.

[0007] Preferably, both the inner and outer cylinders of the filter extend into the recovery chamber, and the bottom end of the inner cylinder of the filter is connected to the interior of the recovery chamber.

[0008] Preferably, the gas storage tank is fixed to one side of the recovery chamber, the recovery chamber is connected to the top of the gas storage tank through a first pipe, and a first pump body is provided on the first pipe, the recovery chamber is connected to the bottom of the gas storage tank through a second pipe, and a filter mechanism is provided on the second pipe, and a second pump body is provided between the filter mechanism and the recovery chamber.

[0011] Preferably, the filtration mechanism includes a housing, a filter screen is provided inside the housing, and a flow control valve is provided at the connection between the first pipe, the second pipe and the recovery chamber.

[0012] The technical effects and advantages of this utility model are as follows: 1. The conical hood effectively disperses the powder, preventing it from piling up in one place. The dispersed powder splashes onto the inner cylinder of the filter screen, making full use of the filter mesh and improving filtration efficiency. At the same time, the multiple conical hoods increase the powder's movement path, slowing down its descent and ensuring more thorough filtration, thus guaranteeing the purity of the filtered powder.

[0013] 2. The bottom of the inner cylinder of the filter screen is connected to the inside of the recovery chamber. The powder filtered by the inner cylinder of the filter screen enters the recovery chamber for collection. The discharge port connected to the bottom of the recovery chamber can smoothly discharge the collected powder, which facilitates subsequent processing and realizes the rapid transfer of recovered powder, improving the continuity of the overall workflow.

[0014] 3. A second pump located between the filtration mechanism and the recovery chamber provides sufficient power for gas recirculation, ensuring smooth gas circulation and enabling efficient recycling of inert gas, thus reducing the consumption cost of inert gas. Furthermore, the housing is designed with a detachable connection, facilitating later opening by personnel to clean the collected powder, achieving secondary powder recovery.

[0019] This utility model provides, for example Figures 1-3 The device shown is a metal powder inert gas protection and recovery device, which includes a recovery chamber 1 and a gas storage tank 2. The recovery chamber 1 and the gas storage tank 2 are connected by a pipeline. The gas storage tank 2 is fixed to one side of the recovery chamber 1 to provide inert gas to the device.

[0020] The top of the recovery chamber 1 is detachably connected to a top cover 6, the top of the top cover 6 is provided with a powder inlet 7, the bottom of the top cover 6 is fixed with a filter inner cylinder 10, and an outer cylinder 9 is provided on the outside of the filter inner cylinder 10. The bottom end of the filter inner cylinder 10 is threadedly connected to a bottom cover 11. A column 12 is fixed to the top of the bottom cover 11. Multiple conical covers 13 are arranged along the height direction of the column 12. The tips of the conical covers 13 are arranged upwards, and the bottom end of the powder inlet 7 is connected to the inside of the filter inner cylinder 10. A gap is left between the outer side of the conical cover 13 and the inner wall of the filter inner cylinder 10.

[0021] Both the inner cylinder 10 and the outer cylinder 9 of the filter screen extend into the recovery chamber 1, and the bottom end of the inner cylinder 10 of the filter screen is connected to the inside of the recovery chamber 1. The bottom end of the recovery chamber 1 is connected to the outlet 8.

[0022] When metal powder enters the inner cylinder of the filter screen 10 from the powder inlet 7, it first falls onto the conical cover 13. The conical cover 13 can disperse the powder and prevent it from accumulating in one place. The dispersed powder splashes onto the inner cylinder of the filter screen 10. The filter holes of the inner cylinder of the filter screen 10 filter the powder. Larger powder particles remain in the inner cylinder of the filter screen 10, while smaller powder particles are discharged. They are blocked by the inner wall of the outer cylinder 9 and eventually fall into the recovery chamber 1, and are subsequently discharged from the outlet 8.

[0023] Gas storage tank 2 is fixed to one side of recovery chamber 1. Recovery chamber 1 is connected to the top of gas storage tank 2 via a first pipe, and a first pump body 4 is installed on the first pipe. Recovery chamber 1 is connected to the bottom of gas storage tank 2 via a second pipe, and a filter mechanism 3 is installed on the second pipe. A second pump body 5 is installed between filter mechanism 3 and recovery chamber 1. Filter mechanism 3 includes a housing, and a filter screen is installed inside the housing. It should be noted that gas storage tank 2 can be connected to a gas input system to replenish gas in a timely manner.

[0024] The first pump 4 pumps the inert gas from the gas storage tank 2 into the recovery chamber 1, maintaining an inert gas environment in the recovery chamber 1 to prevent the metal powder from oxidizing and deteriorating during the recovery process, thus ensuring the quality of the metal powder. The second pump 5 provides power for the gas return flow, drawing the gas from the recovery chamber 1 back to the gas storage tank 2. The drawn-back gas first passes through the filter mechanism 3, which filters the gas returning from the recovery chamber 1 to the gas storage tank 2, removing fine powder carried in the gas and preventing powder from entering the gas storage tank 2 and causing pollution. The powder is blocked by the filter screen inside the box. It should be noted that the box is designed to be detachable, making it easy for personnel to open it later and clean the powder collected inside.

[0025] An auxiliary handle 14 is fixedly connected to the bottom end of the bottom cover 11. The auxiliary handle 14 facilitates the disassembly and installation of the bottom end cover 11 and makes it easier for operators to apply force. When personnel need to process the powder inside the filter inner cylinder 10, they can open the top cover 6, pull out the top cover 6 and the filter inner cylinder 10, and rotate the bottom end cover 11 to allow the powder inside the filter inner cylinder 10 to flow out.

[0026] A flow control valve 15 is installed at the connection between the first pipe, the second pipe and the recovery chamber 1, which can adjust the gas flow rate according to actual needs, so that the gas circulation speed matches the powder recovery speed, thereby improving the flexibility and stability of the device operation.
