[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1 to 13As shown, a refining agent adding device for aluminum liquid refining and purification includes a mixing box 1, a storage cylinder 2, a recovery box 4 and a filter assembly. A support 13 is provided at the bottom end of the mixing box 1. A plurality of storage cylinders 2 connected to the inner cavity of the mixing box 1 are evenly distributed on the upper end of the mixing box 1. The plurality of storage cylinders 2 are arranged along the same horizontal line and are spaced at a fixed distance from each other. A discharge valve 24 is provided at the bottom end of the storage cylinder 2 to discharge the material in the storage cylinder 2 into the mixing box 1 through the discharge valve 24. The filter assembly is arranged inside the storage barrel 2; the recovery box 4 and the storage barrel 2 are arranged respectively correspondingly, and each storage barrel 2 corresponds to a recovery box 4. The bottom end of the recovery box 4 is provided with an inclined bottom plate 42, and the upper and lower sides of the recovery box 4 are provided with through holes 1 41 and through holes 2 43. Through hole 1 41 is located at the top of the recovery box 4, and through hole 2 43 is located at the bottom of the bottom plate 42. Through holes 1 41 and through holes 2 43 are arranged along the same vertical line. The outer wall of the storage barrel 2 is tightly arranged on the inner wall of through hole 1 41 and through hole 2 43, and the lower end of the storage barrel 2 is supported on the upper end of the mixing box 1 to achieve limited fixation. The filter assembly is connected to the lifting mechanism for transmission, which is used to drive the filter assembly to rise and fall along the axial direction of the storage barrel 2. The filter assembly includes a conical filter barrel 74, and the upper circumference of the storage barrel 2 is evenly distributed with a number of discharge slots 21 connected to the recovery box 4. By raising and lowering the filter cartridge 74, the refining agent can be screened, and the refining degree of qualified particles is screened and stored at the bottom of the storage cylinder 2, while the agglomerated large particle refining agent is screened in the storage cylinder 2 at the upper end of the filter cartridge 74. As the filter cartridge 74 rises, the large particle refining agent is squeezed out from the discharge trough 21 and reaches the recovery box 4 for recovery.

[0038] Such a design can filter and separate the materials stored in the storage barrel 2 in real time, and recycle the unqualified large particle refining agent again, thereby avoiding the agglomerated materials from clogging the discharge pipe 51, and also ensuring the uniformity of the discharge particles and the effect of aluminum liquid refining.

[0039] Example 2

[0040] Furthermore, the filtering assembly includes a rotating shaft 7, the lifting mechanism is a cylinder 91, a frame 9 is provided at the upper end of the mixing box 1, the cylinder 91 is arranged on the frame 9, the end of the piston rod 92 of the cylinder 91 is connected to a mounting seat 93, and the upper end of the rotating shaft 7 is arranged on the mounting seat 93.

[0041] The connection between the rotating shaft 7 and the mounting seat 93 can be fixed or movable.

[0042] As one preferred mode, in this embodiment, the rotating shaft 7 and the mounting seat 93 are movably connected, a plurality of openings are evenly distributed on the mounting seat 93, a limiting ring 71 is arranged at the upper end of the rotating shaft 7, the rotating shaft 7 is rotatably arranged on the inner wall of the mounting seat 93 through a bearing 94, and the bottom end of the limiting ring 71 is arranged close to the upper end surface of the mounting seat 93. A rotating mechanism for driving the rotating shaft 7 to rotate is also included. In this case, the rotating shaft 7 can be lifted and lowered by the lifting mechanism while rotating, so as to achieve efficient screening. At the same time, when the filter cartridge 74 rotates, the large-particle refining agent screened at the upper end of the filter cartridge 74 can be rotated and dispersed, making it easier to flow out from the discharge trough 21 to the recovery box 4.

[0043] The rotating mechanism includes a rotating motor 8, a bearing seat 81 and a fixed shaft 82. An L-shaped connecting block 95 is provided at the upper end of the frame 9. One end of the connecting block 95 is fixedly connected to the bearing seat 81. The bearing seat 81 is fixed to the frame 9 through the connecting block 95. A plurality of fixed shafts 82 are rotatably provided inside the bearing seat 81 through a bearing 2 87. One of the fixed shafts 82 is connected to the rotating motor 8 for transmission. A sprocket 83 is provided on the fixed shaft 82. A plurality of sprockets 83 are connected for transmission through a chain 84. A plug-in shaft 85 is provided at the end of the fixed shaft 82.

The convex strip 86 is slidably fitted in the sliding groove 73 to achieve sliding limit of the fixed shaft 82 and the rotating shaft 7. The upper end of the storage barrel 2 is provided with a through hole 3 23, and the rotating shaft 7 extends into the storage barrel 2 through the through hole 3 23. With this design, the cylinder 91 is extended and retracted to realize the lifting and lowering of the rotating shaft 7. At the same time, the rotating shaft 7 is lifted and lowered relative to the fixed shaft 82, and the rotating motor 8 is started to drive the fixed shaft 82 to rotate and drive the rotating shaft 7 to rotate, which has the functions of rotating and lifting the rotating shaft 7, thereby realizing the rotary screening of the filter barrel 74 and the function of extruding the large particle refining agent from the discharge trough 21 after lifting and lowering.

[0044] Furthermore, a plurality of arc-shaped blades 75 are evenly distributed on the circumference of the filter cartridge 74, and the outer diameter of the blades 75 is smaller than the outer diameter of the filter cartridge 74, that is, in the top view direction, as shown in FIG. Fig.12 As shown, the maximum outer diameter of the filter cartridge 74 is larger than the outermost diameter of the blades 75, so that when the filter cartridge 74 slides and rises and falls in the storage cylinder 2, the blades 75 will not interfere with the inner wall of the storage cylinder 2, and when the filter cartridge 74 rotates, it drives the blades 75 to rotate, so that large particles of material can be more easily dispersed by rotation and squeezed out from the discharge trough 21.

[0045] In the present invention, a discharge pipe 51 is provided at the bottom end of the recovery box 4, and a discharge valve 2 54 is provided on the discharge pipe 51. The ends of several discharge pipes 51 are connected to the discharge main pipe 5, and the discharge main pipe 5 is connected to the crushing box 52. Such a design can recover and store the refining agent in each recovery box 4, and discharge it into the crushing box 52 through the respective discharge valves 2 54 for crushing.

[0046] Furthermore, a limiting groove 12 is provided on one side of the mixing box 1 , and the discharge pipe 51 in the middle position is cooperatively arranged in the limiting groove 12 , so as to strengthen the limiting of the recovery box 4 .

[0047] Furthermore, a discharge hose 53 is provided on one side of the crushing box 52, and the discharge hose 53 is connected to a pump body. The discharge hose 53 is used to connect to the storage barrel 2 or the mixing box 1, so that the crushed refining agent can be circulated into the storage barrel 2 again, or passed into the mixing box 1 to achieve recycling.

[0048] Furthermore, a discharge joint 14 is provided on one side of the bottom end of the mixing box 1, and a discharge main pipe 15 is provided on one side of the mixing box 1. The discharge main pipe 15 is connected to a pump body, and the discharge main pipe 15 leads to the inside of the smelting furnace to realize the discharge of the refining agent.

[0049] Furthermore, a feed port 1 22 is provided at the upper end of the storage barrel 2, and the refining agent is fed in through the feed port 1 22, and a feed port 2 11 is provided at the upper end of the mixing box 1. When the discharge hose 53 discharges the material, the discharge hose 53 can be connected to the feed port 1 22 or the feed port 2 11 to realize the discharge. When the materials of multiple recycling boxes 4 are put into the crushing box 52 together for proportioning and crushing, the crushed mixed material can be directly connected to the feed port 2 11 through the discharge hose 53, and passed into the mixing box 1 for stirring again before discharge; when the materials of multiple recycling boxes 4 are discharged and crushed in turn, the crushed materials are connected to the feed port 1 22 of the corresponding storage barrel 2 through the discharge hose 53 to realize recycling, and are filtered again through the filter cartridge 74 before storage.

[0050] It can be seen that the present invention provides a new discharging method, that is, the material after screening by the filter cartridge 74 is divided into qualified material and unqualified material, the qualified material enters the mixing box 1 for mixing and then discharged, and the unqualified material returns to the recovery box 4; the large particle material in the recovery box 4 has two crushing methods, the first is that each material is crushed in turn in the crushing box 52, and then passed into the corresponding storage cylinder 2 for filtering and screening again to repeat the above steps; the second is that each material is crushed together in the crushing box 52 after proportioning, and directly passed into the mixing box 1 for discharge after mixed crushing. Accordingly, in order to ensure the uniformity of the particle size after mixed crushing of multiple materials, one of the storage cylinders 2 and the recovery box 4 can be used as a spare, and materials are not stored at ordinary times. After multiple materials are mixed and crushed in the crushing box 52, they are passed into the spare storage cylinder 2 and the recovery box 4 for filtering to ensure the particle size of the materials.

[0051] Reference Figure 4 A stirring motor 3 is provided at the bottom of the stirring box 1, and a stirring claw 31 is connected to the output shaft of the stirring motor 3. Through the design of the stirring claw 31, the refining agents in multiple storage barrels 2 can be mixed and stirred evenly before discharging.
