Description

Technical Field

[0001] This utility model relates to the technical field of metal powder processing equipment, specifically to a titanium alloy powder dispensing device. Background Technology

[0002] Titanium alloy powder is widely used in aerospace, biomedicine, and 3D printing manufacturing due to its excellent strength-to-weight ratio, corrosion resistance, and biocompatibility. However, titanium alloy powder, especially fine and ultrafine powder, has extremely high chemical reactivity and is highly susceptible to oxidation and even combustion and explosion in air, posing a serious threat to production safety and powder quality. Traditional powder dispensing operations are usually carried out in open workbenches or simple glove boxes, which presents significant problems:

[0003] 1. Poor safety: When titanium powder is handled manually, transferred, or weighed, the powder is exposed to the air, posing an extremely high risk of combustion and explosion, which seriously threatens the personal safety of operators and the safety of company property.

[0004] 2. Severe powder contamination: Oxygen and water vapor in the air react with titanium powder, causing oxidation and moisture absorption on the powder surface, which seriously affects the powder's flowability, sintering performance, and the mechanical properties and chemical composition of the final product, thus reducing product yield.

[0005] 3. Inconvenient operation and low efficiency: The simple glove box has poor sealing performance, consumes a lot of inert gas, and is difficult to maintain a low oxygen environment; in addition, it lacks a dedicated feeding, weighing, dispensing and tool transfer system, making the operation process cumbersome and inefficient. Utility Model Content

[0006] The purpose of this invention is to provide a titanium alloy powder dispensing device in order to address the shortcomings of existing technologies.

[0007] To achieve the above objectives, the technical solution of this utility model is to design a titanium alloy powder dispensing device, including a material tank, a weighing and feeding device, a vacuum chamber, a vacuum sealing machine, and a main frame. The material tank, weighing and feeding device, vacuum chamber, and vacuum sealing machine are arranged within the main frame. The material tank is connected to the weighing and feeding device. A feeding port is provided above the vacuum chamber, and the weighing and feeding device is connected to the feeding port. The vacuum sealing machine is connected to the vacuum chamber. A glove opening and an observation window are provided on one side of the vacuum chamber, and a first door is provided on the other side of the vacuum chamber. A displacement air inlet and a displacement air outlet are provided on the vacuum chamber. The weighing and feeding device is preferably a loss-in-weight or gain-in-weight feeder. The vacuum sealing machine is located inside or below the vacuum chamber and is connected to the vacuum chamber. The observation window can be a partially transparent window or a fully transparent window, and the glove opening is located on the side of the transparent window.

[0008] Furthermore, the vacuum chamber is equipped with a circulating exhaust port and a circulating air inlet, which are connected by a pipe. In the inert atmosphere environment inside the chamber, an external circulating purification device continuously circulates and purifies the protective gas, removing any trace amounts of oxygen and water vapor that may accumulate, maintaining the high purity of the atmosphere inside the chamber over a long period, and reducing the consumption of inert gas.

[0009] Furthermore, a transition chamber is connected to the outside of the first door, and a second door is provided on the outside of the transition chamber. The transition chamber is typically connected to a vacuum pump and also has vacuuming and inert gas replacement functions. The transition chamber is used for items (such as containers and tools to be packaged) to enter and exit the main vacuum chamber. During operation, the items are first placed in the transition chamber, the second door is closed, the transition chamber is evacuated, and then inert gas is introduced until the pressure equalizes with the main chamber. Finally, the first door is opened to move the items into the main chamber. This process greatly reduces air intrusion and inert gas loss caused by directly opening the main chamber door, improves operational efficiency, and maintains a stable environment within the main chamber.

[0010] Furthermore, the vacuum chamber is equipped with an oxygen monitoring interface. This interface connects to an oxygen analyzer to monitor the oxygen concentration inside the chamber in real time. This real-time monitoring ensures that the material distribution process is always conducted in a safe and qualified low-oxygen environment, guaranteeing powder quality and operational safety.

[0011] Furthermore, the vacuum chamber is equipped with a water monitoring interface. This interface is used to connect a water content analyzer to monitor the water vapor content in the chamber environment in real time. Real-time monitoring ensures that the material distribution process is always carried out in a safe and qualified low-moisture environment, guaranteeing powder quality and operational safety.

[0012] Furthermore, a feeding rack is provided on the main frame, and the feeding rack is connected to the material tank. The feeding rack provides a stable platform, facilitating operators to safely and accurately feed large packages of titanium alloy powder into the material tank.

[0013] Furthermore, a tool compartment is connected to the outside of the vacuum chamber. The tool compartment is an independent, small, sealed chamber, typically equipped with a vacuum pump and also capable of vacuuming and inert gas replacement, used to store the tools required for operation. When needed, tools can be sent into the main chamber or transition chamber via a connecting channel or a small pass-through window without opening the main chamber or transition chamber, improving the convenience of tool retrieval and environmental maintenance efficiency.

[0014] Furthermore, the vacuum chamber is equipped with shelves. The shelves are used to place empty containers (such as bottles and boxes) to be dispensed, dispensed containers, or other items that need to be temporarily stored in the chamber, keeping the interior space neat and tidy and facilitating operation.

[0015] Furthermore, pressure gauges are installed on the vacuum chamber, transition chamber, and tool compartment. These pressure gauges are used to monitor the pressure in each compartment.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. The core operation is completed in a sealed vacuum chamber. By evacuating the vacuum and replacing it with an inert gas, the titanium alloy powder is always kept in a low-oxygen or oxygen-free environment, which fundamentally eliminates the risk of oxidation, combustion or explosion of the powder when it comes into contact with air during the material distribution process, and greatly ensures the safety of operators and equipment.

[0018] 2. The inert gas or vacuum environment effectively isolates oxygen and water vapor, significantly reducing the degree of oxidation and moisture absorption of the powder during the material distribution process, ensuring the purity, flowability and sintering activity of the powder, thereby improving the performance and quality stability of the final product.

[0019] 3. The weighing and feeding device ensures the consistency and reliability of powder packaging weight.

[0020] 4. The design of the circulating exhaust port and air inlet allows connection to an external gas purification system to circulate, purify, and reuse the gas inside the chamber, significantly reducing the consumption of high-purity inert gas and operating costs. Attached Figure Description
