Technical Field

[0001] The utility model relates to the technical field of aluminum water refining and filtering, in particular to a refining and filtering device. Background Art

[0002] Molten aluminum refers to molten aluminum, which usually becomes a liquid state under high temperature conditions. This is a stage in the production and refining process of aluminum, which involves heating solid aluminum to a high enough temperature to melt it to form liquid aluminum to ensure that the final aluminum product has the required purity and properties. Molten aluminum is the main material for the production of aluminum rods. Molten aluminum needs to be refined and filtered before use to ensure that the final aluminum product has the required purity and properties.

[0003] For example, the Chinese patent with publication number CN217149281U, an aluminum refining filter box, includes a filter box body, a partition is arranged in the filter box body, the partition divides the filter box body into two left and right areas, the left side is the filter area, and the right side is the sedimentation area; a support platform is arranged in the filter area, and a filter component is installed on the support platform, the filter component includes a first filter component and a second filter component, the first filter component is installed on the support platform, and the second filter component is located above the first filter component; the second filter component includes a restraining frame and a plurality of corundum balls arranged in the restraining frame, the edge of the restraining frame is in contact with the side of the filter area, and the bottom of the restraining frame is installed on the first filter component; a connecting hole is arranged at the bottom of the partition, and the filter area is connected with the sedimentation area through the connecting hole, and a feed inlet and a discharge port are arranged on the filter box body.

[0004] In the above scheme, the staff uses the first filter component, the second filter component and the filter box to filter and precipitate the solid particles in the molten aluminum. However, the molten aluminum also contains various impurities and gases, such as iron oxide, hydrogen and oxygen, resulting in the following disadvantages: filtration and precipitation can only filter the solid particles in the molten aluminum, and the oxides and gases in the molten aluminum cannot be removed, resulting in poor aluminum refining effect, which in turn affects the quality and performance of aluminum rod production. Utility Model Content

[0005] The utility model aims to provide a refining and filtering device to solve the problem that the refining effect of molten aluminum is not good and the quality and performance of aluminum rod production are affected.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a refining and filtering device, including a box body, both sides of the inner wall surface of the box body are provided with slide grooves, an aluminum liquid filter screen is slidably arranged between the two slide grooves, two fixing strips are fixed to the top surface of the aluminum liquid filter screen, a hook hole is provided on one side of the fixing strip, an air inlet hole is provided on one side of the inner wall surface of the box body, and an air inlet pipe is fixed to the inside of the air inlet hole.

[0007] Preferably, a discharge hole is opened on one side of the box body, the inside of the discharge hole is connected to and fixed with a discharge pipe, and one end of the discharge pipe away from the box body is connected to and fixed with a valve.

[0008] Preferably, a base is provided below the box body, rotating shafts are fixed on both sides of the box body, a sleeve plate is movably sleeved on the outer circular wall of the rotating shaft, the bottom surface of the sleeve plate is fixed to the top surface of the base, and one side of the base is an inclined surface.

[0009] Preferably, both sides of the box body are provided with limiting grooves, and the top surface of the base is hinged with two limiting shafts, and the limiting shafts are inserted into the limiting grooves.

[0010] Preferably, a pad is placed on the inclined surface of the base, and the top surface of the pad fits with the bottom surface of the box.

[0011] Preferably, the top surface of the box body is rotatably connected with a mounting cover via a hinge.

[0012] Compared with the prior art, a refining and filtering device using the above technical solution has the following beneficial effects:

[0013] 1. During use, the staff will pour the molten aluminum that needs to be refined and filtered into the box. When the molten aluminum enters the box, the molten aluminum filter will filter it for the first time to remove solid impurities in the molten aluminum. After the molten aluminum filter has been filtered for many times, the staff can use the fixing bar and the hook hole to pull out the molten aluminum filter to clean its surface to prevent clogging. The filtered molten aluminum will accumulate inside the box. Then the staff will connect the air inlet pipe to nitrogen or argon and inject nitrogen or argon into the molten aluminum in the box. Nitrogen or argon will react with the oxides and gases in the molten aluminum, thereby removing the gas and impurities in the molten aluminum, improving the molten aluminum refining effect and facilitating the production of high-quality aluminum bars.

[0014] 2. During use, after the aluminum liquid is filtered and refined, the staff can open the valve to discharge the aluminum liquid in the box through the discharge pipe, so that the staff can discharge the aluminum liquid in the box conveniently. When discharging the aluminum liquid in the box, the staff can use the base to tilt the box at a certain angle, so that the aluminum liquid in the box is close to the discharge pipe, so that the aluminum liquid can be discharged more thoroughly. The staff can use the insertion of the limit shaft and the limit groove to limit the box above the base, so as to prevent the box from tilting on the top surface of the base when in use, thereby improving the safety of the device;

[0015] 3. During use, when the box is tilted for discharging, the pad supports the bottom of the box to further prevent the risk of the box being skewed. After the staff puts the molten aluminum into the box, they can close the installation cover to keep the molten aluminum in a closed environment in the box, thereby reducing the entry of external gas into the box and further reducing the gas impurities in the molten aluminum.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, a refining and filtering device comprises a box body 1, both sides of the inner wall surface of the box body 1 are provided with slide grooves 2, an aluminum liquid filter screen 3 is slidably arranged between the two slide grooves 2, two fixing strips 4 are fixed to the top surface of the aluminum liquid filter screen 3, one side of the fixing strip 4 is provided with a hook hole 5, one side of the inner wall surface of the box body 1 is provided with an air inlet hole 6, the inside of the air inlet hole 6 is connected and fixed with an air inlet pipe 7, the air inlet pipe 7 is made of graphite material, one side of the box body 1 is provided with a discharge hole 8, the inside of the discharge hole 8 is connected and fixed with a discharge pipe 9, and the end of the discharge pipe 9 away from the box body 1 is connected and fixed with a valve 10.

[0023] During use, the staff pours the molten aluminum that needs to be refined and filtered into the box body 1. When the molten aluminum enters the box body 1, the molten aluminum filter 3 will perform an initial filtration on it to remove solid impurities in the molten aluminum. After the molten aluminum filter 3 has been filtered for multiple times, the staff can use the fixing bar 4 and the hook hole 5 to clean the surface of the molten aluminum filter 3 to prevent clogging. The filtered molten aluminum will accumulate inside the box body 1. Then the staff will connect the air inlet pipe 7 to nitrogen or argon gas, and inject nitrogen or argon gas into the molten aluminum in the box body 1. The nitrogen or argon gas will react with the oxides and gases in the molten aluminum, thereby removing the gases and impurities in the molten aluminum, improving the molten aluminum refining effect, and facilitating the production of high-quality aluminum rods. After the molten aluminum is filtered and refined, the staff can open the valve 10 to discharge the molten aluminum in the box body 1 through the discharge pipe 9, thereby facilitating the staff to discharge the molten aluminum in the box body 1.

[0024] like Figure 2-Figure 4 As shown, a base 11 is provided at the bottom of the box body 1, and a rotating shaft 12 is fixed on both sides of the box body 1. A sleeve 13 is movably sleeved on the outer circular wall of the rotating shaft 12. The bottom surface of the sleeve 13 is fixed to the top surface of the base 11. One side of the base 11 is an inclined surface. Limiting grooves 14 are provided on both sides of the box body 1. Two limiting shafts 15 are hinged on the top surface of the base 11, and the limiting shafts 15 are inserted into the limiting grooves 14.

[0025] During use, when the staff is discharging the molten aluminum in the box body 1, they can use the base 11 to tilt the box body 1 at a certain angle, so that the molten aluminum in the box body 1 is close to the discharge pipe 9, allowing the molten aluminum to be discharged more thoroughly. The staff can use the insertion of the limit shaft 15 and the limit groove 14 to limit the box body 1 above the base 11, thereby preventing the box body 1 from tilting on the top surface of the base 11 when in use, thereby improving the safety of the device.

[0026] like Figure 2-Figure 4 As shown, a pad 16 is placed on the inclined surface of the base 11, the top surface of the pad 16 is in contact with the bottom surface of the box body 1, and the top surface of the box body 1 is rotatably connected to a mounting cover 17 through a hinge.

[0027] During use, when the box 1 is tilted for discharging, the pad 16 supports the bottom of the box 1 to further prevent the risk of the box 1 being skewed. After the staff puts the molten aluminum into the box 1, they can close the installation cover 17 to make the molten aluminum in a closed environment in the box 1, thereby reducing the outside gas from entering the box 1, and further reducing the gas impurities in the molten aluminum.
