Description

Technical Field

[0001] This utility model relates to melt purification technology in the preparation process of aluminum and aluminum alloys, specifically an integrated device for purifying aluminum melts. Technical Background

[0002] With the rapid development of industries such as electronics, aerospace, automobiles, photovoltaics, and powder metallurgy, the demand for high-end aluminum products has expanded rapidly. Today, the extreme control requirements of the electronics industry on the chemical composition of high-purity aluminum and high-quality aluminum alloys have made the quality control of aluminum and aluminum alloy melts extremely important, placing higher demands on the control of non-metallic and metallic trace elements and minute inclusions in the aluminum melt during the aluminum product manufacturing process.

[0003] Currently, aluminum alloy melt purification technology mainly employs granular refining agents and rotary refining degassing devices for impurity and degassing of molten aluminum. This process primarily involves two steps: first, the addition of granular refining agents. A rotating graphite rod with an inert gas jet function at the bottom stirs the molten aluminum to create a vortex, and then the granular refining agent is poured into the vortex through a conduit. Under the influence of the vortex, the granular refining agent is drawn into the interior of the molten aluminum. Second, refining and degassing. After the granular refining agent is poured in, the baffle is lowered to a designated depth in the molten aluminum, the vortex disappears, and the rotating graphite rod continues to rotate and jet until the set time is completed, thus completing the refining and degassing of the molten aluminum. However, existing equipment consists of smelting furnaces of ten or tens of tons, each with its own specific stirring and refining / degassing devices, resulting in a relatively fixed smelting environment. Furthermore, the granular refining agent is added continuously. Existing equipment is not suitable for the development of new products in the aluminum industry and cannot flexibly meet the needs of small crucibles under one ton or the refining of multiple varieties. Therefore, how to provide an integrated device for purifying aluminum melt to meet the needs of small crucible or multi-variety refining, as well as the combination or single use of gas and flux to meet the needs of different smelting environments and targeted selection, is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an integrated device for purifying aluminum melt, so as to solve the problems existing in various scenarios in actual production process and improve the process capability of purifying aluminum melt in production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated device for purifying aluminum melt includes a column, a working arm, and an operating console. The column is mounted on a moving platform via a rotary support, and the moving platform is equipped with a guide rail for mounting the rotary support. The working arm is connected to the column by a rotating shaft, which can adjust the tilt angle of the arm. A lifting motor is fixedly installed below the column to drive a chain to move the working arm up and down.

[0007] Preferably, the working arm is fixed with a feeding motor that feeds material in a screw manner, which adds the refining agent in the powder storage tank into the melt of the smelting crucible at a certain speed. A graphite baffle is also provided on the baffle lifting guide rail, and the graphite baffle is driven to move up and down by the baffle lifting motor to ensure that the refining agent falls into the melt.

[0008] Preferably, the mobile platform is used to carry the operation console and the rotating support, and the bottom of the mobile platform is equipped with lockable casters.

[0009] Preferably, the lifting device of the column can support the working cantilever to move up and down a distance of 1m.

[0010] Preferably, the pivot of the working arm can support a maximum tilt angle of 45°.

[0011] Preferably, the rotating support can support the column to rotate 180°, while the guide rail can support the column to move left and right by 0.2m.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model is equipped with a mobile platform, and the system shape and posture can be adjusted by columns and rotating supports to adapt to specific alloy smelting operation sites. It can use degassing or refining functions separately according to product process needs, achieving the effect of multiple uses in one machine, and meeting the refining needs of multiple small-equivalent crucible furnaces.

[0014] 2. This utility model integrates a rotary degassing system and a refining agent feeding system on the working arm, which can realize the integration of automatic powder feeding function on the simple degassing function, and at the same time improve the purity of the melt.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1 As shown, this utility model provides an integrated device for purifying aluminum melt, the core of which is a mobile rotary degassing system, mainly including a column 1, a working arm 2, a rotary support 3, an operation control console 4, and a mobile platform 5; the working arm 2 is equipped with a rotary degassing system and a refining agent feeding system; the working arm 2 and the column 1 are rotatably connected by a rotating shaft 2.1, and the column 1 is mounted on the mobile platform 5 via the rotary support 3; the mobile platform 5 is equipped with a guide rail 3.1 for mounting the rotary support 3. A lifting motor 1.1 is fixedly installed below the column 1, which can drive the chain 1.2 to move, causing the working arm 2 to rise and fall along the length of the column.

[0021] A graphite rotating shaft 2.2 is provided on the working cantilever 2. The lower end of the graphite rotating shaft 2.2 is provided with a graphite rotor nozzle 2.3, and the graphite rotor nozzle 2.3 is connected to the gas cylinder 2.10 through a gas pipe arranged inside the equipment. The graphite rotating shaft 2.2 is driven to rotate by a rotary motor 2.4, so that the graphite rotating shaft 2.2 can rotate around its own axis, thereby simultaneously driving the graphite rotor nozzle 2.3 to rotate around its axis as well, so that gas can be introduced into the melt through the graphite rotor nozzle 2.3 to realize the stirring and degassing of the melt. In addition, a feeding motor 2.6 is fixed on the working cantilever 2 to feed material by means of a screw push, adding the refining agent in the powder storage tank 2.5 into the melt of the smelting crucible at a certain speed. A graphite baffle 2.7 is also provided, which is located on the baffle lifting guide rail 2.8. The graphite baffle 2.7 is driven by the baffle lifting motor 2.9 to move up and down in the vertical direction to ensure that the refining agent falls into the melt and prevents the refining agent from falling into other places. The operation control console 4 is used to control the operation of each motor and the air supply system. The mobile platform 5 is used to support the operation control console 4 and the rotating support 3 system, etc. The mobile platform 5 is equipped with lockable casters 5.2 and a manual hydraulic lifting handle 5.1.

[0022] See Figure 2The working cantilever 2 can be lifted vertically upwards by a rotary motor 2.4. Specifically, the rotary motor 2.4, through a transmission mechanism (which can use bevel gears or a universal joint), lifts the working cantilever 2 upwards to form a certain angle with the column 1 and fixes it in that position. See [link to relevant documentation] Figure 3 The working cantilever 2 can be rotated around the axis of the column 1 by the rotating support 3.

[0023] Working Principle: This utility model is an integrated device for purifying aluminum melt. Before use, the refining agent is added to the powder storage tank 2.5 according to the required amount for the refining process. The user adjusts the position of the entire device by pushing the moving platform 5, depending on the specific conditions of the smelting site. Then, the position of the working cantilever 2 is adjusted manually by adjusting the rotating support 3, the rotating shaft 2.1, and the guide rail 3.1. Specifically, the user manually adjusts the rotating support 3 so that the column 1 connected to the rotating support 3 can rotate around its axis; the user manually pushes the working cantilever 2 to rotate around the column 1 via the rotating shaft 2.1; the user manually pushes the rotating support 3 to slide along the guide rail 3.1; finally, the working cantilever 2 is adjusted to the appropriate position. The control console 4 controls the lifting motor 1.1 to work, thereby adjusting the lifting and lowering of the working cantilever 2 to ensure that the graphite rotor nozzle 2.3 can penetrate deeply into the melt. During operation, the parameters of each motor and the gas flow rate are adjusted via the control cabinet 4. The rotary motor 2.4 simultaneously drives the graphite shaft 2.2 and the graphite rotor nozzle 2.3 to rotate around the axis of the graphite shaft 2.2. The gas cylinder 2.10 is switched on, allowing gas to pass through the graphite rotor nozzle 2.3 into the melt, achieving stirring and degassing of the melt. The baffle lifting motor 2.8 is controlled via the control console 4, driving the graphite baffle 2.7 to rise and fall to the discharge port. The feeding motor 2.6 is started, pushing the refining agent from the powder storage tank 2.5 into the vortex generated by the melt stirring, achieving refining of the melt. After degassing or refining, all motors are turned off via the control console 4. The working cantilever 2 is raised so that the graphite rotor nozzle 2.3 leaves the melt, and the melt residue on the rotor nozzle 2.3 is cleaned.

[0024] This invention allows for the separate use of degassing or refining functions, or for simultaneous degassing and refining, effectively improving the efficiency and effectiveness of melt purification.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions.
