Description

Technical Field

[0001] The utility model relates to the technical field of atomization powder-making equipment, and specifically relates to a spray disc structure for metal atomization powder-making. Background Technique

[0002] Atomization powder-making is generally divided into water atomization powder-making and gas atomization powder-making. In water atomization powder-making, first, an electric furnace or an induction furnace is used to melt metal raw materials into alloy liquid with qualified components (generally superheated by 100 - 150 °C), and then it is poured into a tundish located above the atomization nozzle. The alloy liquid flows out from the leakage hole at the bottom of the tundish and meets a high-speed air flow or water flow when passing through the nozzle, and is atomized into fine droplets. The atomized droplets quickly solidify into alloy powder in a closed atomization cylinder.

[0003] For example, the utility model with the application number CN202220786938.0 discloses an alloy powder gas atomization spray disc. This utility model can use a spray head to spray an inert gas on molten metal, atomize the molten metal to produce metal powder, and can conveniently and quickly adjust the angle between the spray head and the molten metal. By adjusting the angle of the spray head, the inert gas ejected by it can generate air flows with different intensities on the molten metal, so that different molten metals can be maximally atomized in the spray disc body, improving the powder output rate. However, the inner wall of the spray disc body is prone to adhesion of metal powder. Excessive accumulation is difficult to clean and affects the use effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a spray disc structure for metal atomization powder-making is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spray disc structure for metal atomization powder-making to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A spray disc structure for metal atomization powder-making, including a spray disc main body and a cleaning component.

The cleaning component is arranged outside the spray disc main body, and the cleaning component includes a fixed frame, a lead screw, a hand crank, a lead screw nut, a first scissors arm, a moving frame, a second scissors arm, a slider, a connecting piece, and a scraping ring. The lead screw is installed inside the fixed frame, and the right end of the lead screw penetrates through the right side of the fixed frame and is connected with a hand crank. The outside of the lead screw is connected with a lead screw nut, and the middle of the lead screw nut is connected with a first scissors arm through a rotating shaft. The other end of the first scissors arm is connected with a moving frame through a rotating shaft, and the middle of the first scissors arm is connected with a second scissors arm through a rotating shaft. The rear end of the second scissors arm is connected with a slider through a rotating shaft. A connecting piece is arranged at the rear end of the moving frame, and the end of the connecting piece penetrates through the through groove and is connected with a scraping ring.

[0007] Furthermore, an inlet hole is formed in the middle of the spray disc body, and an air storage cavity is arranged inside the spray disc body.

[0008] Furthermore, an air spray pipe is connected inside the air storage cavity, and a spray head is installed at the other end of the air spray pipe.

[0009] Furthermore, a fixing plate is installed at the top end inside the spray disc body, and electric telescopic rods are arranged on both sides of the fixing plate.

[0010] Furthermore, the output end of the electric telescopic rod is connected with a support arm, and the bottom of the support arm is rotationally connected with the spray head through a rotating shaft.

[0011] Furthermore, the top of the spray head is rotationally connected with a ring frame through a rotating shaft, and the spray disc body is fixedly connected with the ring frame.

[0020] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figure 1 and Figure 2 shown, a spray disc structure for metal atomization powder making includes a spray disc main body 1 and a cleaning assembly 11. Through grooves 10 are opened on both sides of the spray disc main body 1. The cleaning assembly 11 is arranged outside the spray disc main body 1, and the cleaning assembly 11 includes a fixed frame 1101, a lead screw 1102, a hand crank 1103, a lead screw nut 1104, a first scissors arm 1105, a moving frame 1106, a second scissors arm 1107, a slide block 1108, a connecting piece 1109 and a wall scraping ring 1110. The lead screw 1102 is installed inside the fixed frame 1101, and the right end of the lead screw 1102 penetrates through the right side of the fixed frame 1101 and is connected with the hand crank 1103. The outside of the lead screw 1102 is connected with the lead screw nut 1104, and the middle part of the lead screw nut 1104 is connected with the first scissors arm 1105 through a rotating shaft. The other end of the first scissors arm 1105 is connected with the moving frame 1106 through a rotating shaft, and the middle part of the first scissors arm 1105 is connected with the second scissors arm 1107 through a rotating shaft. The rear end of the second scissors arm 1107 is connected with the slide block 1108 through a rotating shaft. A connecting piece 1109 is arranged at the rear end of the moving frame 1106, and the end of the connecting piece 1109 penetrates through the through groove 10 and is connected with the wall scraping ring 1110. The fixed frame 1101 and the moving frame 1106 are parallel to each other, and the end of the second scissors arm 1107 far away from the slide block 1108 is rotatably connected with the fixed frame 1101 through a rotating shaft.

[0022] The specific operation is as follows. When the lead screw nut 1104 horizontally displaces along the outside of the lead screw 1102, it can change the crossing angle of the first scissors arm 1105 and the second scissors arm 1107, causing the moving frame 1106 to drive the wall scraping ring 1110 fixed to the connecting piece 1109 to scrape along the inner wall of the spray disc main body 1, thereby scraping off the adhered metal powder and ensuring the cleanliness of the inner wall of the spray disc main body 1.

[0023] As Figure 1 and Figure 3As shown in the figure, an inlet hole 2 is provided in the middle of the spray disc body 1, and an air storage cavity 3 is arranged inside the spray disc body 1. A spray gas pipe 4 is connected inside the air storage cavity 3, and the other end of the spray gas pipe 4 is provided with a spray head 5. A fixed plate 6 is installed at the top end inside the spray disc body 1, and electric telescopic rods 7 are arranged on both sides of the fixed plate 6. The output end of the electric telescopic rod 7 is connected with a support arm 8, and the bottom of the support arm 8 is rotationally connected with the spray head 5 through a rotating shaft. The top of the spray head 5 is connected with an annular frame 9 through a rotating shaft, and the spray disc body 1 is fixedly connected with the annular frame 9.

[0024] The specific operation is as follows. When the electric telescopic rod 7 extends outwards or retracts inwards, its outer end can drive the support arm 8 to rotate, causing the spray head 5 to rotate around the rotating shaft on the annular frame 9, so as to adjust the angle of the spray head 5, making the inert gas ejected by it generate airflows with different intensities on the molten metal falling at the inlet hole 2, ensuring the powder making effect and making it more flexible to use.

[0025] In summary, for the spray disc structure used for metal atomization powder making, during use, first, shake the hand crank 1103 to provide a rotational force for the lead screw 1102, so that the lead screw nut 1104 makes a horizontal rightward displacement along the outside of the lead screw 1102, causing the slider 1108 to slide at the chute on the surface of the moving frame 1106, and the connecting piece 1109 slides in the through groove 10, making the cross angle of the first shear arm 1105 and the second shear arm 1107 change, so as to adjust the scraping wall ring 1110 to the same height as the annular frame 9;

[0026] Then during operation, the molten metal falls into the spray disc body 1 through the inlet hole 2 under the influence of gravity. At this time, the inert gas in the air storage cavity 3 is sent to the spray head 5 through the spray gas pipe 4, and the spray head 5 sprays the molten metal at high pressure to atomize the molten metal into metal powder. During this period, by controlling the electric telescopic rod 7 to extend outwards or retract inwards, the support angle of the support arm 8 on the spray head 5 can be changed, making the angle of the spray head 5 adjustable, so as to ensure the powder making effect;

[0027] During powder making, some metal powder will adhere to the inner wall of the spray disc body 1. When powder making stops, by shaking the hand crank 1103, the lead screw nut 1104 makes a horizontal leftward displacement along the outside of the lead screw 1102. By changing the cross angle of the first shear arm 1105 and the second shear arm 1107, the moving frame 1106 and the scraping wall ring 1110 continuously descend vertically under the guiding action of the connecting piece 1109, so as to scrape off the metal powder adhering to the inner wall of the spray disc body 1, ensuring the cleanliness of the inner wall of the spray disc body 1 and preventing the metal powder from depositing on the inner wall of the spray disc body 1.

[0028] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
