Description

Technical Field

[0001] The utility model relates to the field of preparation of metal alloy powders, and particularly to a device for preparing a thermally sprayed self-bonding metal alloy powder. Background Technique

[0002] Thermal spraying is an important method for preparing metal alloy coatings and improving the service performance of metal materials by using metal alloy powders as raw materials. During the preparation process of metal alloy powders, metal raw materials need to be put into a grinding device for grinding to form powders, and then mixed to form metal alloy powders. Therefore, a device for preparing a thermally sprayed self-bonding metal alloy powder is required.

[0003] According to the publicly disclosed patent 202222817361.8, a metal atomization device for TC4 titanium alloy powder includes an atomization tank. The top surface of the atomization tank is provided with an openable cover body. The lower surface of the atomization tank is fixedly installed with a powder collection chamber. The side of the powder collection chamber is provided with a vacuum pump suction pipe. The inner wall of the atomization tank is provided with a plasma torch. The bottom surface of the inner wall of the atomization tank is provided with a discharge port. The inner wall of the discharge port is fixedly connected with a discharge baffle. The top surface of the discharge baffle is slidably connected with a sealing barrier element. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. By setting the sealing barrier element and rotating the rotatable rod to misalign the first discharge hole and the second discharge hole, the solid position of the barrier baffle covers the position of the first discharge hole on the discharge baffle, separating the atomization tank from the powder collection chamber to solve the problems of substances and oxygen in the air corroding and oxidizing the metal powder, and the powder collection chamber and the atomization tank being in a communicating state and unable to be separated. During use, the traditional device for preparing a thermally sprayed self-bonding metal alloy powder only uses two jet heads installed opposite to each other to atomize the metal liquid entering the alloy powder atomization spray box. During the atomization process of the metal liquid, some metal liquid is prone to incomplete atomization, and the atomized metal powder cannot be screened. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0005] To achieve the object of the present utility model, the technical solution adopted by the present utility model is: to design a device for preparing a thermally sprayed self-bonding metal alloy powder, including an alloy powder atomization spray box, an external surface of the alloy powder atomization spray box is fixedly connected with a hexagonal protective sleeve, an outer surface of the hexagonal protective sleeve is provided with two groups of inclined panels at different angles, and a gas supply pipe and a jet head are connected to each of the two groups of inclined panels at different angles through a pipe joint, and a top end of the alloy powder atomization spray box is integrally formed with an alloy liquid injection port.

[0006] Preferably, a bottom end of the alloy powder atomization spray box is connected with a sieve box through a support plate, a top end of the sieve box is hermetically connected to a discharge port of the alloy powder atomization spray box and is communicated with an interior thereof.

[0007] Preferably, two sides inside the sieve box are fixedly connected with vibration motors, a sieve mesh is connected above the vibration motors through a carrier plate, and a door panel is movably installed outside the sieve box.

[0020] Embodiment 1: A device for preparing self-bonding metal alloy powder for thermal spraying, see Figures 1 to 3 , including an alloy powder atomization spray box 1. A hexagonal protective sleeve 11 is fixedly connected to the outside of the alloy powder atomization spray box 1. Two groups of inclined panels 12 with different angles are arranged on the outer surface of the hexagonal protective sleeve 11. An air supply pipe 14 and a jet head 15 are connected to each of the two groups of inclined panels 12 with different angles through a pipe joint 13. An alloy liquid injection port 16 is integrally formed at the top of the alloy powder atomization spray box 1. Each group of inclined panels 12 has three. Two of the groups of inclined panels 12 are fixedly connected to the outer surface of the hexagonal protective sleeve 11 at intervals. One group of pipe joints 13 forms a 60-degree angle with the installation surface of one group of inclined panels 12, and the other group of pipe joints 13 forms a 30-degree angle with the installation surface of the other group of inclined panels 12. One end of the air supply pipe 14 is hermetically connected to one end of the pipe joint 13, and one end of the jet head 15 is hermetically connected to the other end of the pipe joint 13. The other end of the jet head 15 is located inside the alloy powder atomization spray box 1. By arranging two groups of jet heads 15 with different angles in the alloy powder atomization spray box 1, the metal liquid in the alloy powder atomization spray box 1 can be stratified and atomized, avoiding the phenomenon that some of the metal liquid is not thoroughly atomized during the atomization process, and can atomize the metal liquid entering the alloy powder atomization spray box 1 in all directions, improving the uniformity of the metal alloy powder preparation device during the preparation process.

[0021] Specifically, see Figure 1 and Figure 3, the bottom end of the alloy powder atomization spray box 1 is connected to a sieve box 21 through a support plate 2. The top end of the sieve box 21 is hermetically connected to the discharge port of the alloy powder atomization spray box 1 and is communicated with its interior. Vibration motors 22 are fixedly connected to both sides inside the sieve box 21. Above the vibration motors 22, a sieve mesh 24 is connected through a carrier plate 23. A door panel 25 is movably installed outside the sieve box 21. When the atomized metal alloy powder enters the interior of the sieve box 21, the vibration motors 22 will cause vibration inside the sieve box 21, so as to screen the metal powder falling on the sieve mesh 24, thereby improving the efficiency in the preparation of alloy powder.
