Description

Technical Field

[0001] The utility model relates to the field of special metallurgy, in particular to a double-furnace smelting vacuum air atomization powder making system. Background Art

[0002] With the widespread application of 3D metal printing in various industries, the demand for spherical metal powder is increasing, and improving the production capacity of related products is becoming increasingly important. The time it takes to melt metal in induction furnaces of the same power generally does not vary significantly. If the waiting time for adding materials can be effectively shortened, productivity can be greatly improved.

[0003] Vacuum Inert Gas Atomization (VIGA) is an advanced equipment that crushes metal or alloy melt into spherical powder under vacuum and inert gas protection.

[0004] The traditional method for feeding a vacuum atomization powder production system involves opening the furnace lid to add the metal or alloy raw materials into the crucible in the vacuum furnace. The lid is then closed to induce vacuum for melting, and the molten metal is then transferred to the atomization device. The disadvantage of this method is that opening the lid, adding materials, closing the lid, and transferring the molten metal requires considerable man-hours, resulting in low production efficiency. Furthermore, these operations require manual labor, which impacts production efficiency and creates safety risks. Utility Model Content

[0005] The Summary of the Utility Model introduces a series of simplified concepts, which are simplifications of existing technologies in the field and are further described in detail in the Detailed Description of the Utility Model. The Summary of the Utility Model of this utility model is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] The technical problem to be solved by the utility model is to provide a double-furnace smelting vacuum air atomization pulverizing system which can improve the production efficiency of the vacuum air atomization pulverizing system and realize continuous pulverizing production.

[0007] In order to solve the above technical problems, the utility model provides a double-furnace smelting vacuum gas atomization powder making system, which consists of a vacuum melting device, an atomization device, a powder collecting device and a bracket;

[0008] a powder collecting device arranged on the ground below the support;

[0009] An atomizing device, wherein the feed end thereof is arranged in a sealed cavity on the bracket, and the powder discharge end thereof is sealedly connected to a powder collecting device;

[0010] The vacuum melting device includes: a first vacuum melting furnace and a second vacuum melting furnace symmetrically arranged on both sides of a sealed cavity, the first vacuum melting furnace and the second vacuum melting furnace are fixed on a first furnace cover and a second furnace cover respectively, the first furnace cover and the second furnace cover can alternately seal the sealed cavity, and the liquid outlet ends of the first vacuum melting furnace and the second vacuum melting furnace can alternately transport molten metal to the feed end of the atomization device.

[0011] Optionally, the double-furnace smelting vacuum air atomization powder making system can be further improved, wherein the first furnace cover is connected to the first pivot drive device on its right side;

[0012] a second furnace cover, the left side of which is connected to a second pivot drive device;

[0013] a first pivot drive device capable of driving the first furnace cover to rotate around the pivot within a specified plane to a specified angle to form a seal with the sealing cavity;

[0014] The second pivot drive device can drive the second furnace cover to rotate around the pivot in a specified plane to a specified angle to form a seal with the sealing cavity.

[0015] Optionally, the dual-furnace smelting vacuum air atomization powder making system can be further improved to include:

[0016] A manual button is electrically connected to the first pivot drive device and the second pivot drive device respectively, and is used to start the first pivot drive device and the second pivot drive device to rotate.

[0017] Optionally, the dual-furnace smelting vacuum air atomization powder making system can be further improved so that the first pivot drive device drives the first vacuum smelting furnace to rotate in a direction opposite to the direction in which the second pivot drive device drives the second vacuum smelting furnace to rotate.

[0018] Optionally, the dual-furnace smelting vacuum air atomization powder making system can be further improved to include:

[0019] A timer, which starts the melting start timer from the first vacuum melting furnace or the second vacuum melting furnace and sends a trigger signal to the manual button after reaching a specified time;

[0020] a manual button, electrically connected to the first pivot drive device and the second pivot drive device, respectively, for starting the first pivot drive device and the second pivot drive device to rotate;

[0021] The trigger signal is electrically conductive, that is, the manual button cannot be powered on if the specified smelting time is not reached, thereby significantly improving the metal smelting quality and production safety.

[0022] Optionally, the dual-furnace smelting vacuum air atomization powder making system can be further improved to include:

[0023] The PLC controller sends a trigger signal to control the first vacuum melting furnace and the second vacuum melting furnace to perform alternating melting and casting, that is, through calibration combined with PLC control, the first vacuum melting furnace and the second vacuum melting furnace can achieve continuous alternating melting and casting.

[0024] The working process of this utility model is as follows:

[0025] At least one of the two vacuum melting furnaces is charged. For example, after charging the first vacuum melting furnace, the pivot drive mechanism connected to the first vacuum melting furnace rotates, forming a sealed connection between the first furnace cover and the sealed chamber, providing a vacuum environment for melting, and then starting the melting process to obtain molten metal. Simultaneously, the second vacuum melting furnace is being charged.

[0026] The molten metal is transported to the atomizing device to complete the powder making, and then collected by the powder collecting device.

[0027] The vacuum environment is broken, causing the first furnace cover to separate from the sealed chamber and rotate to the initial filling station. Simultaneously, the pivot drive device connected to the second vacuum melting furnace is driven to rotate, forming a sealed connection between the second furnace cover and the sealed chamber. After providing a vacuum environment for melting, melting is started to obtain molten metal. At the same time, the first vacuum melting furnace is in the initial filling station and filling is carried out.

[0028] This cycle repeats itself to achieve uninterrupted production.

[0029] The utility model can at least achieve the following technical effects:

[0030] 1. The utility model adopts double-furnace smelting. When one vacuum melting furnace performs metal smelting and subsequent powder making, the other vacuum melting furnace performs filling and preparation, which reduces the waiting time of single-furnace melting and filling, and greatly improves the metal powder production efficiency.

[0031] 2. The utility model can control the double furnace smelting manually (manual button), semi-automatic (timer combined with manual button) or fully automatic (PLC control). No matter which control method is adopted, it avoids the safety hazards caused by manual operation and can greatly improve production safety.

[0032] 3. The utility model can realize continuous and uninterrupted powder production through the double-furnace smelting joint control method.

[0033] Accordingly, under the design principle of the present invention, the production efficiency can be further improved by increasing the number of vacuum melting furnaces, for example, designing three or even more vacuum melting furnaces to perform alternating melting and casting.
