Description

Technical Field

[0001] The utility model mainly relates to the technical field of powder manufacturing, in particular to a spray disc device for automatic water-gas atomization powder making in powder metallurgy. Background Art

[0002] In the process of alloy powder manufacturing, the alloy metal liquid needs to be atomized into fine particle powder under the action of high-pressure water flow or high-pressure air flow. Common air flows are compressed air, high-pressure nitrogen and argon. Atomized powder has a high balling rate and a large bulk density. The compression performance varies depending on the shape of the powder. In industry, air is often used to atomize aluminum and copper powders; nitrogen is used to atomize high-speed steel powders; argon is used to atomize high-temperature alloys; and high-pressure water is used to atomize copper, nickel, cobalt and other metals or alloys that are not easily oxidized. Atomization powder making has become the basis of new technologies in powder metallurgy.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] If there are impurities in the liquid sprayed by the current spray disc, the water outlet will be blocked, resulting in the inability to spray the spray hole, and during use, the distance of the spray disc spraying the liquid is limited. After searching, for example, patent application number CN202321186218.1 discloses a spray disc for atomizing furnace for refining powders, which includes: a spray disc body, a joint is fixedly installed in the middle of the top of the spray disc body, a fixed seat is fixedly installed inside the joint, a spring is fixedly installed in the middle of the fixed seat, a pressure plate is fixedly installed on the top of the spring, a through head is arranged around the bottom of the pressure plate, a water outlet is opened around the middle of the inside of the spray disc body, a socket is fixedly installed in the middle of the spray disc body, a screw head is fixedly installed inside the socket, and a limiting disk is fixedly installed at the bottom of the screw head. In the utility model, the pressure plate slides downward on the top of the fixed seat, so that the through-head arranged around the bottom of the pressure plate can slide inside the water outlet, and the dirt blocking the water outlet can be poked out, so that the water outlet remains unobstructed, and through the setting of the spring, after being pressed, the pressure plate will rebound to the top of the fixed seat to prevent the water outlet from being blocked. Although the application can rebound the pressure plate through the setting of the spring, the force of the spring is relative. When the pressure plate rebounds, it is easy to cause the pressure plate to move back and forth due to excessive force, causing impact damage to the pressure plate. The elasticity of the spring needs to gradually disappear before the pressure plate can be returned to its original position, and the spring is easy to get stuck, resulting in the pressure plate being unable to rebound; secondly, although the spray distance of the liquid has been lengthened, the lengthened distance is fixed, and the length of the liquid spray distance cannot be adjusted.
