Description

Technical Field

[0001] The present application relates to the technical field of aluminum liquid purification, and in particular to an explosion-proof air release device for an aluminum liquid impurity removal device. Background Art

[0002] When processing aluminum materials, the aluminum ingots are first melted into aluminum liquid, and then sent to a purification box for purification to remove impurities in the aluminum liquid, improve the purity of the aluminum liquid, and obtain high-quality aluminum alloy materials.

[0003] Typically, various impurity removal methods are used when purifying molten aluminum. These include using refining agents, activated carbon, and other components within the purification chamber to adsorb and separate impurities. Alternatively, ventilation is used, such as introducing oxygen into the chamber. This oxygen reacts with impurities in the molten aluminum, converting them into easily removable oxides. Purification chambers are primarily used to contain the molten aluminum and provide a reaction space. These chambers are fitted with a lid. This refining process, which involves introducing air into the molten aluminum, results in elevated pressure within the chamber. Furthermore, the high temperature within the chamber exacerbates this high pressure, posing a safety hazard.

[0004] Regarding the above-mentioned related technologies, if the problem is solved by opening a vent on the purification box, it may cause excessive deflation; if the problem is solved manually, not only will the operation be delayed and troublesome, but there will also be safety hazards. Therefore, a method that is both safe and can solve the overpressure problem in a timely manner is needed. Utility Model Content

[0005] In order to discharge gas in time when the air pressure exceeds a preset value during the aluminum liquid impurity removal process, the present application provides an explosion-proof air venting device for an aluminum liquid impurity removal device.

In a natural state, the pressure relief cover covers the pressure relief pipe and can close the pipe opening of the pressure relief pipe.

[0008] By adopting this technical solution, the pressure relief pipe, mounting base, and pressure relief cover work together to allow gas to be safely released through the pressure relief pipe when internal pressure rises abnormally during the aluminum liquid processing process, preventing the device from exploding.

[0016] By adopting the above technical solution, the cooperation between the thread and the fixing nut realizes the firm fixation of the counterweight block, preventing the counterweight block from falling off or loosening during use. This fixing method is convenient and fast.

[0017] Optionally, the upper surface of the pressure relief pipe is arranged to be inclined downward in a direction away from the counterweight rod, and the pressure relief cover is inclined to cover the pressure relief pipe.

[0018] By adopting the above technical solution, the inclined design of the pressure relief pipe and the pressure relief cover is conducive to the smooth discharge of gas and impurities, reducing the risk of blockage.

[0021] Optionally, a positioning seat is provided on the side wall of the pressure relief pipe, and a positioning piece is provided on the positioning seat.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses an explosion-proof air release device for aluminum liquid impurity removal device. Figure 1 The explosion-proof air release device is mainly installed on the box cover 102 above the purification box 101. It includes a pressure relief pipe 1, a mounting seat 2 and a pressure relief cover 3. The pressure relief pipe 1 is arranged on the upper surface of the box cover 102, the mounting seat 2 is arranged on the side wall of the pressure relief pipe 1, and the pressure relief cover 3 is rotatably arranged on the mounting seat 2. In the natural state, the pressure relief cover 3 covers the pressure relief pipe 1 and can close the pipe opening of the pressure relief pipe 1; when the air pressure in the purification box 101 increases to exceed the preset value, the air pressure can push the pressure relief cover 3 upward, so that the pressure relief cover 3 rotates along the mounting seat 2, that is, it can open the pipe opening at the upper end of the pressure relief pipe 1 for pressure relief. With this design, when the pressure in the purification box 101 exceeds the preset value, the pressure relief pipe 1 can be automatically opened, thereby ensuring the safety inside the purification box 101.

[0036] Reference Figure 1 and Figure 2 In this embodiment, the pressure relief pipe 1 is preferably configured as a circular tube, preferably made of a high-strength, high-temperature-resistant alloy material, such as stainless steel. The lower end of the pressure relief pipe 1 is fixed to the box cover 102 by welding or other means, and the pressure relief pipe 1 is connected to the space inside the purification box 101.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the mounting base 2 includes two mounting plates 21 and a rotating shaft 22 rotatably disposed between the two mounting plates 21. The mounting plate 21 is preferably configured in an L-shape, the lower end of which can be fixed to the side wall of the pressure relief pipe 1 by screws or welding, and the two mounting plates 21 are disposed in parallel. The rotating shaft 22 is rotatably connected to the two mounting plates 21 at both ends, and can be rotatably connected by bearings or other means. In order to facilitate material acquisition and reduce device costs, the rotating shaft 22 is preferably a screw. Both mounting plates 21 are provided with openings for the rotating shaft 22 to pass through. The rotating shaft 22 is limited at both ends by threaded nuts, and the rotating shaft 22 is rotatably connected to the two mounting plates 21.

[0038] Reference Figure 1 and Figure 2In this embodiment, a connecting rod 31 is welded to the upper surface of the pressure relief cover 3. One end of the connecting rod 31 extends out of the pressure relief cover 3 and is fixedly connected to the rotating shaft 22 by welding or other means. The connection point is preferably located at the midpoint of the rotating shaft 22. When the air pressure in the purification box 101 exceeds a preset value, the gas can drive the pressure relief cover 3 to flip upward along the rotating shaft 22 to relieve pressure.

[0039] Reference Figure 1 and Figure 2 In this embodiment, a counterweight rod 4 is welded and fixed to the side wall of the rotating shaft 22. The counterweight extends away from the connecting rod 31. This counterweight reduces the force exerted on the pressure relief cover 3, thereby adjusting the preset air pressure. Furthermore, a counterweight block 41 can be provided on the counterweight rod 4. Multiple counterweight blocks 41 can be provided, facilitating adjustment of the preset air pressure. A fixing member 5 is also provided on the counterweight rod 4 for securing the counterweight block 41.

[0040] Reference Figure 2 In this embodiment, the counterweight 41 can be made of a nut with a larger inner diameter, which can be quickly installed on the counterweight rod 4; the outer side of the counterweight rod 4 is provided with a thread, and the fixing member 5 includes two fixing nuts 51, which are respectively provided on both sides of all the counterweights 41, and the fixing nuts 51 are threadedly connected to the counterweight rod 4, so that the counterweight 41 can be restricted from sliding along the length direction of the counterweight rod 4 through the two fixing nuts 51, thereby fixing the counterweight 41; when the counterweight needs to be adjusted, it is only necessary to unscrew the outer fixing nut 51 to adjust the counterweight 41 placed on the counterweight rod 4, thereby changing the weight of the entire counterweight structure, and then adjusting the force required to push the pressure relief cover 3 upward, that is, the preset value of the air pressure can be adjusted. In other embodiments, the fixing member 5 can also be in the form of a pin or a buckle to restrict the sliding of the two sides of the counterweight 41 to fix the counterweight 41.

[0041] Reference Figure 1 and Figure 3 In an optional embodiment, the upper surface of the pressure relief pipe 1 is arranged to be inclined downward in a direction away from the counterweight rod 4, that is, the upper surface of the pressure relief pipe 1 is an inclined surface, and the pressure relief cover 3 is correspondingly arranged as an elliptical cover and is inclined to cover the pressure relief pipe 1. During the impurity removal process of the aluminum liquid in the purification box 101, impurities may be attached to the air after the bubbles burst upward. When the pressure relief cover 3 is lifted, some of the impurities will condense into liquid and adhere to the pressure relief cover 3. When the impurities are finally condensed into solids, they will accumulate on the upper surface of the pressure relief pipe 1, making it impossible to seal the pressure relief pipe 1. Therefore, with this inclined setting, impurities on the surface of the pressure relief pipe 1 can flow along the inclined surface and out of the upper surface of the pressure relief pipe 1, reducing the possibility of impurities accumulating on the surface of the pressure relief pipe 1.

[0042] Reference Figure 1 and Figure 3In an optional embodiment, in order to facilitate the collection and cleaning of impurities, the explosion-proof air release device also includes a slag collecting box 6, and a slag storage tank is provided on the upper surface of the slag collecting box 6. The slag collecting box 6 is arranged on the side of the pressure relief pipe 1 away from the counterweight rod 4, that is, on the side of the pressure relief pipe 1 with a lower surface height. The side of the slag collecting box 6 close to the pressure relief pipe 1 is arranged into an arc surface to increase the contact area with the pressure relief pipe 1, so that the liquid condensed on the slag collecting pipe can be collected by the slag collecting box 6 after flowing and dripping along the surface of the slag collecting pipe.

[0043] Reference Figure 1 and Figure 3 In an optional embodiment, a recess 12 is further provided on the side wall of the pressure relief pipe 1 facing away from the counterweight rod 4, and the side wall of the slag collecting box 6 can be recessed into the recess 12. The recess 12 facilitates positioning of the slag collecting box 6 and allows impurities on the pressure relief pipe 1 to flow directly into the slag storage tank, thereby improving collection efficiency.

[0044] Further optionally, a positioning seat 11 is welded and fixed to the side wall of the pressure relief pipe 1. Two positioning seats 11 can be symmetrically provided, so that when the slag collecting box 6 is embedded in the embedding groove 12, the side walls of the slag collecting box 6 at both ends respectively abut against the side walls of the positioning seat 11. The positioning seat 11 is provided with a positioning member 7 for fixing the positioning seat 11 to the slag collecting box 6. The positioning seat 11 and the positioning member 7 can limit the movement of the slag collecting box 6 during use, thereby improving the stability of the equipment.

[0045] The positioning member 7 can be a positioning rod 71. In other embodiments, the positioning member 7 can also be a structure such as a latch. Specifically, the positioning rod 71 includes a first rod and a second rod bent at the end of the first rod. The first rod is rotatably mounted on the positioning seat 11. It can be achieved by providing an annular groove on its side wall, or by positioning with a bearing or nut. The second rod is located on the side of the positioning seat 11 close to the slag collecting box 6. It is vertically connected to the first rod to form a bent portion. A slot 61 for the positioning rod 71 to be inserted is correspondingly provided on the side wall of the slag collecting box 6. A landing groove is also provided in the slag collecting box 6. After the positioning rod 71 is inserted along the slot 61, the user releases the hand. Under the action of gravity, the bent portion of the positioning rod 71, i.e., the second rod, can be rotated and fall into the landing groove, thereby limiting the movement of the slag collecting box 6 relative to the positioning seat 11.

[0046] Further optionally, since the impurities are difficult to clean after solidification, an inner box 8 can be set in the slag collecting box 6. The inner box 8 is made of high-temperature resistant metal material, and a ring edge 81 is fixed at its upper end. When in use, impurities flow into the inner box 8 and solidify. When there are many impurities, it is only necessary to remove the inner box 8 upwards through the ring edge 81 for replacement.

[0047] The implementation principle of the explosion-proof air release device for a molten aluminum impurity removal device according to the embodiment of the present application is as follows: before use, an appropriate counterweight 41 is first set on the counterweight rod 4 according to the preset air pressure value. During use, the pressure relief cover 3 is closed on the upper end of the pressure relief pipe 1. When the air pressure in the purification box 101 is too high, the pressure difference between the inside and outside causes the pressure relief cover 3 to be pushed upward, and the gas is discharged from the upper end of the pressure relief pipe 1. After the pressure relief is completed, the pressure relief cover 3 is closed again on the pressure relief pipe 1 under the action of gravity.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
