Description

Technical Field

[0001] This utility model relates to the field of copper alloy smelting technology, and in particular to a copper alloy smelting feeding device. Background Technology

[0002] Non-vacuum melting of copper alloys offers advantages such as low production costs and large product sizes, but solving the challenges of non-vacuum melting is crucial. Alloying by adding trace amounts of alloying elements can effectively improve the overall properties of copper. However, because the added alloying elements have a strong affinity for oxygen and a lower density than copper, they tend to float on the surface of the molten copper during melting, resulting in significant burn-off and difficulty in precise control. An existing copper alloy melting and feeding device (CN 222298522 U) involves inserting a graphite tube into the molten copper alloy to a fixed depth and then introducing inert gas. When alloying elements need to be added, alloy powder from the feeding tank is placed into the inlet pipe. The inert gas carries the alloy powder through small holes in the graphite tube and sprays it into the molten copper alloy, thus achieving the melting and feeding of the copper alloy. However, after the alloy powder is added to the feeding tank, the adsorption between alloy powder molecules makes it difficult for the powder to enter the graphite tube using only inert gas, affecting the efficiency of alloy powder addition. Utility Model Content

[0003] The purpose of this invention is to provide a copper alloy smelting and feeding device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

The charging mechanism includes a mounting frame fixed on the lifting assembly. A vent pipe and a graphite tube are disposed at the lower position of the mounting frame. The graphite tube is vertically downward and has through holes evenly distributed on its lower outer wall. The inlet end of the vent pipe is connected to an inert gas source. A molecular sieve and a charging hopper are disposed on the vent pipe. The molecular sieve is located between the charging hopper and the inlet end of the vent pipe. A sealing cover is installed at the upper end of the charging hopper.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-7 As shown, a copper alloy smelting feeding device includes a support mechanism disposed on one side of a smelting furnace. The support mechanism includes a rotating support assembly, a lifting assembly fixedly disposed on the rotating support assembly, and a feeding mechanism installed on the lifting assembly. After an inert gas is introduced, the feeding mechanism causes the alloy powder to be fed out and mixed with the gas as it flows through the gas and enters the molten liquid.

[0030] In this embodiment: the rotating support assembly includes a fixed frame 11, a support shaft 12 is vertically arranged on the fixed frame 11, a turntable is fixed to the upper end of the support shaft 12, a worm gear 13 is installed on the support shaft 12 inside the fixed frame 11, a worm 14 is meshed on one side of the worm gear 13, and a first power component 15 is connected to one end of the worm 14; the support shaft 12 is rotatably connected to the fixed frame 11, and the worm 14 is rotatably connected to the fixed frame 11. The first power component 15 drives the worm 14 to rotate, so that the worm 14 meshes with the worm gear 13 and drives the support shaft 12 and the lifting assembly to rotate as a whole, thereby moving the position of the feeding mechanism relative to the smelting furnace.

[0031] In this embodiment, the lifting assembly includes a vertical frame 21 fixed to the upper end of the turntable. A lead screw 22 and a guide post 23 are vertically arranged on the vertical frame 21. A crossbeam 25 is installed on the lead screw 22 and the guide post 23. A second power component 24 is connected to the upper end of the lead screw 22. The crossbeam 25 is fixedly connected to the mounting bracket 31. The lead screw 22 is rotatably connected to the vertical frame 21. The lead screw 22 is threadedly connected to the crossbeam 25. The crossbeam 25 is slidably connected to the guide post 23. The second power component 24 drives the lead screw 22 to rotate, so that the lead screw 22 pushes the crossbeam 25 to move up and down under the limit of the guide post 23, which facilitates the extraction or insertion of the graphite tube 34 into the molten liquid of the smelting furnace. The first power component 15 and the second power component 24 are existing servo motors or other power sources that can provide forward and reverse rotation. This is conventional technology and will not be described in detail here.

[0032] In this embodiment: the feeding mechanism includes a mounting frame 31 fixed on the lifting assembly. A vent pipe 32 and a graphite tube 34 are connected and pass through each other at the lower position of the mounting frame 31. The graphite tube 34 is vertically downward and has through holes evenly distributed on its lower outer wall. An inert gas source is connected to the air inlet end of the vent pipe 32. A switch valve is installed between the inert gas source and the vent pipe 32. A molecular sieve 35 and a feeding hopper 33 are installed on the vent pipe 32. The lower side of the feeding hopper 33 is cylindrical and the upper side is conical. The molecular sieve 35 is located between the feeding hopper 33 and the air inlet end of the vent pipe 32. The molecular sieve 35 absorbs and filters the moisture in the inert gas. A sealing cover 36 is installed at the upper end of the feeding hopper 33. A feeding assembly is installed inside the feeding hopper 33 to move the alloy powder inside the feeding hopper 33 downward when the inert gas moves from the vent pipe 32 to the graphite tube 34. The feeding assembly includes a rotating shaft 37 vertically positioned at the center of the feeding hopper 33. An impeller 38 is mounted on the rotating shaft 37 within a vent pipe 32. Agitating rods 39 are circumferentially spaced along the outer diameter of the rotating shaft 37 above the impeller 38, and auger blades 310 are positioned on the upper outer diameter of the rotating shaft 37. The rotating shaft 37 is rotatably connected to the vent pipe 32 and the feeding hopper 33. The outer diameter of the auger blades 310 is tangent to the inner diameter of the lower cylindrical section of the feeding hopper 33. At least two layers of agitating rods 39 are arranged axially along the rotating shaft 37, with the upper and lower layers of agitating rods 39 arranged crosswise. After the graphite tube 34 is inserted into the molten metal in the smelting furnace, the agitating rods 39 will... Inert gas is introduced into the vent pipe 32. As the gas moves from the vent pipe 32 to the graphite tube 34, it drives the impeller 38 on the lower side of the rotating shaft 37 to rotate. The impeller 38 drives the stirring rod 39 and the auger blade 310 on the rotating shaft 37 to rotate. The auger blade 310 conveys the alloy powder on the upper side of the feeding hopper 33 downwards. The stirring rod 39 diffuses the alloy powder on the lower side of the feeding hopper 33. Then, along with the flowing gas, the powder enters the graphite tube 34 and is injected into the molten liquid through the through hole on the lower side of the graphite tube 34. This improves the mixing effect of the alloy powder in the feeding hopper 33 with the inert gas in the vent pipe 32.

[0033] A viewing window is provided on the outer wall of the cone on the upper side of the feeding hopper 33. The upper end of the auger blade 310 extends into the cone on the upper side of the feeding hopper 33, which facilitates observation and confirmation when the auger blade 310 rotates with the rotating shaft 37 to stir and feed the alloy powder in the feeding hopper 33. A handle is fixed on the upper end of the sealing cover 36, and a sealing ring 361 is provided on the lower inner wall of the sealing cover 36. Locking buckles are evenly distributed around the circumference between the sealing cover 36 and the feeding hopper 33, so that the sealing cover 36 is fastened to the upper end of the feeding hopper 33, forming a sealed state inside the feeding hopper 33.

[0034] The working principle and usage process of this utility model are as follows: Alloy powder is added into the feeding hopper 33, and the sealing cover 36 is fastened to the upper end of the feeding hopper 33 by a lock. When alloy powder needs to be added into the melting furnace, the first power component 15 drives the worm gear 14 to rotate, so that the worm gear 14 meshes with the worm wheel 13, driving the support shaft 12 and the vertical frame 21 to rotate as a whole, moving the mounting bracket 31 on the crossbeam 25 above the melting furnace. Then, the second power component 24 drives the lead screw 22 to rotate, so that the lead screw 22 pushes the crossbeam 25 downward under the limit of the guide column 23, moving the graphite tube 3... 4. The material is inserted into the molten liquid in the smelting furnace. Then, inert gas is introduced into the vent pipe 32. As the gas moves from the vent pipe 32 to the graphite tube 34, it drives the impeller 38 on the lower side of the rotating shaft 37 to rotate. The impeller 38 drives the stirring rod 39 and the auger blade 310 on the rotating shaft 37 to rotate. The auger blade 310 conveys the alloy powder on the upper side of the feeding hopper 33 downwards. The stirring rod 39 diffuses the alloy powder on the lower side of the feeding hopper 33. Then, the powder enters the graphite tube 34 with the flowing gas and is injected into the molten liquid through the through hole on the lower side of the graphite tube 34.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
