[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0064] See also Figure 1-Figure 16 , the present invention provides two technical solutions:

[0065] Embodiment 1: A casting aluminum alloy refining treatment device includes a refining tank 1, and an equipment box 2 is arranged at the bottom of the refining tank 1, and a refining treatment mechanism is arranged inside the refining tank 1 for realizing the fusion of aluminum solution and refining agent and removing the generated impurities, and the refining treatment mechanism includes:

[0066] The processing box 3 is located inside the refining tank 1 and slides, and a pneumatic component 5 is provided at the bottom to realize the vertical lifting of the processing box 3, and a driving component 4 is provided at the top to realize the rotation of the internal components of the processing box 3;

[0067] The refining and desulfurizing section 6 is located inside the processing box 3 to achieve the mixing of the aluminum solution and the molten refining agent and the discharge of the generated impurities, including the use of a rotating bearing to rotate a rotating shaft 61 installed at the center of the processing box 3, the surface of the rotating shaft 61 is installed with a stirring plate 62 located inside the processing box 3, and the surface of the rotating shaft 61 is provided with a dredging unit 7 to achieve the lifting of the impurities caught in the holes and is located at the bottom side of the processing box 3, and when the rotating shaft 61 moves vertically upward, the pushing section 8 arranged inside removes the impurities concentrated on one side of the stirring plate 62, and the surface of the processing box 3 is provided with a discharge trough 63.

[0068] By providing a refining treatment mechanism, the pneumatic component 5 is used to drive the treatment box 3 to move deeper into the solution, and then the driving component 4 is used to rotate the stirring plate 62, so as to complete a more uniform treatment operation without the need for human operation and pressing. After the reaction is completed, the impurities are concentrated by the stirring plate 62, and the impurities are discharged during the subsequent vertical movement operation, thereby completing the automated refining treatment, and realizing the reaction operation and impurity removal operation more efficiently and completely, so that the quality of the refined product is guaranteed.

[0069] The surface of the refining tank 1 is respectively provided with discharge ports for impurities after the reaction, and the entry of the refining agent is measured by a delivery pump. After the refining agent is transferred, it enters the bottom of the processing box 3, and a liquid inlet groove 71 is opened at the bottom of the processing box 3 to balance the air pressure and realize the passage of the molten refining agent and the aluminum alloy solution. The liquid inlet groove 71 cannot pass impurity particles larger than its diameter. When the refining agent is dissolved in the aluminum alloy solution and has not yet reacted, the processing box 3 has moved to the bottom of the inner cavity of the refining tank 1 to contact it, and then the reaction of the refining agent and the aluminum alloy solution produces aggregated large-particle impurities and is located above the processing box 3, and the processing box 3 is located in the vertical direction. Movement does not produce rotation, and only the vertical movement operation is maintained.

[0070] When the processing box 3 moves to contact the bottom of the inner cavity of the refining tank 1, the gap between the two is very small, and no impurities fall into the gap between the two. Therefore, when removing the impurities, it is only necessary to remove the impurities on the top of the processing box 3. At the same time, the surface of the processing box 3 is in sliding contact with the inner wall of the refining tank 1, and the solution can flow without passing through the impurity particles.

[0071] See also Figure 1-Figure 4 In the embodiment of the present invention, the driving assembly 4 includes a driving motor 41 fixedly mounted on the top of the refining tank 1, and a driving shaft 42 is mounted on one end of the output shaft of the driving motor 41 through a coupling, and a sliding assembly 43 is provided between the driving shaft 42 and the rotating shaft 61 to achieve relative sliding;

[0072] The pneumatic assembly 5 includes a cylinder 51 installed in the equipment box 2 , and a piston rod 52 is slidably connected inside the cylinder 51 . The top end of the piston rod 52 extends into the interior of the refining tank 1 and rotates with the bottom end of the rotating shaft 61 .

[0073] The drive motor 41 is a three-phase asynchronous motor, the drive motor 41 is electrically connected to an external power supply, the cylinder 51 is connected to an external air circuit, and both the drive motor 41 and the cylinder 51 can be opened and closed by a person operating a control panel.

[0074] See also Figure 3 The sliding assembly 43 includes a slide bar 431 symmetrically mounted on the surface of the rotating shaft 61, and a slide groove 432 adapted to slide with the slide bar is opened on the inner side of the driving shaft 42, and the slide bar 431 and the slide groove 432 slide relative to each other and maintain the synchronous rotation operation of the rotating shaft 61 and the driving shaft 42.

[0075] See also Figure 15-16 In the embodiment of the present invention, the dredging unit 7 comprises:

[0076] The liquid inlet grooves 71 are located on the bottom side of the processing box 3 and are equidistantly arranged in a circle;

[0077] The dredging plate 72 is installed on the surface of the rotating shaft 61, and the top of the dredging plate 72 is equidistantly provided with placement grooves 73 corresponding to the liquid inlet groove 71. A support rod 74 is slidingly passed through the inside of the placement groove 73, and a dredging column 76 is installed on the top of the support rod 74. A resisting spring 75 is sleeved on the surface of the support rod 74, and the two ends of the resisting spring 75 are fixed to the opposite sides of the dredging column 76 and the placement groove 73. When the dredging column 76 moves to the bottom of the liquid inlet groove 71, the elastic force of the resisting spring 75 realizes the extension of the dredging column 76 into the inside of the liquid inlet groove 71.

[0078] By providing the dredging unit 7, when the dredging column 76 moves to the liquid inlet tank 71, the elastic force of the spring 75 enables the dredging column 76 to move into the liquid inlet tank 71, and pushes the impurities that are caught, and then cooperates with the sweeping of the stirring plate 62 to concentrate the impurities, which not only effectively avoids the problem of solution filtration blockage caused by impurity-caught holes, but also can more completely clean the impurities and reduce multiple reciprocating cleaning operations.

[0079] When the dredging column 76 moves to the liquid inlet groove 71, the elastic force of the supporting spring 75 enables the dredging column 76 to move into the liquid inlet groove 71 and push the stuck impurities. The dredging column 76 is in a truncated cone shape, and when the dredging plate 72 continues to rotate, the dredging column 76 is pressed into the inside of the placement groove 73, which on the one hand realizes the pushing and dredging of impurities, and on the other hand ensures the fluidity of the liquid inlet groove 71.

[0080] See also Figure 6-Figure 13 In the embodiment of the present invention, the pusher 8 comprises:

[0081] The control shaft 81, the top and bottom ends of the control shaft 81 are combined with a rotating assembly 83 to realize the rotation operation of the control shaft 81 after being pushed, and the main bevel gear 82 is installed inside the rotating shaft 61, and the control shaft 81 and the main bevel gear 82 are also connected by a sliding assembly 43 to realize the relative sliding of the control shaft 81 and the main bevel gear 82 and maintain the synchronous rotation operation of the control shaft 81 and the main bevel gear 82;

[0082] The push plate 84 and the surface of the main bevel gear 82 are provided with a traction assembly 9 to enable the push plate 84 to slide in the extension direction of the stirring plate 62, and a blocking assembly 85 is provided at the end face of the stirring plate 62 in the extension direction to realize the centralized operation of impurities before degreasing, and the push plate 84 and the stirring plate 62 are horizontally moved in the extension direction of the stirring plate 62 through a moving assembly 86.

[0083] The main bevel gear 82 is rotationally connected to the inside of the rotating shaft 61 through a connected bracket, and a slide groove 432 is provided inside the bracket connected to the main bevel gear 82, and a slide bar is installed on the surface of the control shaft 81, and the slide bar 431 and the slide groove 432 are adapted to slide.

[0084] See also Figure 6-Figure 7 In the embodiment of the present invention, the rotating assembly 83 includes:

[0085] The circular plate 831 is fixedly mounted on the upper inner side of the rotating shaft 61, and the control shaft 81 passes through the circular plate 831 and can rotate relative to the circular plate 831. The control shaft 81 extends to the upper side of the rotating shaft 61 and the extending end is connected with the abutment plate 832. The surface of the control shaft 81 is sleeved with a torsion spring 833, and the two ends of the torsion spring 833 are fixed to the opposite sides of the circular plate 831 and the abutment plate 832.

[0086] The hollow column 834 is fixedly mounted on the inner bottom of the rotating shaft 61 , and a spiral annular groove 835 is formed on the surface of the hollow column 834 . A control column 836 is mounted below the surface of the control shaft 81 , and the control column 836 slides inside the annular groove 835 .

[0087] The overall upward movement of the processing box 3 causes the rotating shaft 61 to drive the internal control shaft 81 to move upward synchronously until the abutment plate 832 on the control shaft 81 begins to contact the top of the inner side of the driving shaft 42. At this time, the driving motor 41 stops working and self-locks, while the cylinder 51 continues to push the processing box 3 upward, so that the control shaft 81 is abutted and moved downward. At this time, under the sliding control of the control column 836 and the annular groove 835, the control shaft 81 rotates to realize the subsequent pushing operation. During normal rotation operation, the hollow column 834 will contact the upper port of the annular groove 835 and maintain the overall rotation of the internal structure of the rotating shaft 61.

[0091] When the left rotating shaft 91 rotates, the reel wheel 94 on the left rotating shaft 91 is driven to reel in the reel rope 95, thereby driving the push plate 84 to drive the concentrated impurities to fall into the discharge trough 63, and at this time the right rotating shaft 92 is in the state of releasing the rope. The reel rope 95 is made of a good stainless steel material, which can withstand heat and has higher corrosion resistance than the aluminum alloy solution, and does not react with the aluminum alloy solution, and is flexible and can be bent and wound;

[0092] The winding rope 95 connected to the winding wheel 94 on the left rotating shaft 91 sequentially passes through the rotating shaft 61, the stirring plate 62 and the front plate 851 and extends to the inside of the concave groove 862, and is fixed to one side of the convex block 861 on the pushing plate 84 through the steering support of the support assembly 96.

[0096] By providing the baffle assembly 85, when the impurity removal is in the final stage and the impurity mass is not enough to push the baffle plate 852, the convex block 861 pushes the movable rack 854 to contact the flip gear 855 and realize the rotation of the flip gear 855, thereby opening the baffle plate 852 to continue to discharge the impurities, which can not only realize the operation of more complete discharge of impurities, but also avoid overflow from the discharge trough 63 when the refining agent is started to be injected, thereby realizing better subsequent refining and decontamination operations.

[0104] During operation, the refining agent is transferred to the surface of the aluminum solution through the delivery pump and is located below the processing box 3, and then the pneumatic component 5 is used to realize the rapid vertical downward movement of the processing box 3. At this time, the refining agent is pressed into the aluminum alloy solution, and then the refining agent is dissolved in the aluminum alloy solution and flows through the liquid inlet tank 71 below the processing box 3. At this time, the processing box 3 moves to the bottom of the inner cavity of the refining tank 1 to contact, and the refining agent is dissolved in the aluminum alloy solution and then reacts to achieve the aggregation of impurities. Then, by starting the driving motor 41, the driving shaft 42 drives the rotating shaft 61 and the stirring plate 62 to fuse the refining agent and the aluminum alloy solution;

[0105] The impurities generated after the reaction are located in the processing box 3, and the pneumatic assembly 5 is used to drive the processing box 3 to perform a reset operation and continue to move upward until the top of the abutting plate 832 contacts the top of the inner side of the driving shaft 42. When the rotation of the rotating shaft 61 causes the dredging column 76 to move to the liquid inlet groove 71, the elastic force of the abutting spring 75 enables the dredging column 76 to move into the liquid inlet groove 71, and pushes the clamped impurities to fall into the processing box 3;

[0106] Then, the impurity particles are concentrated in the groove of the stirring plate 62 through the rotation of the stirring plate 62, and then the impurities are driven to rotate to the discharge groove 63;

[0107] At this time, continuing to move the processing box 3 upward will drive the abutment plate 832 to abut against the top of the inner side of the driving shaft 42. At this time, the torsion spring 833 is compressed, and the control shaft 81 moves downward, and under the limit of the hollow column 834 and the annular groove 835, the control shaft 81 rotates, and the rotation of the control shaft 81 drives the rotation of the main bevel gear 82, and the main bevel gear 82 drives the secondary bevel gear 93 connected to the left rotating shaft 91 to rotate, and the winding wheel 94 on the left rotating shaft 91 performs the winding operation of the winding rope 95, so that the convex block 861 above the pushing plate 84 moves horizontally inside the concave groove 862 to complete the pushing operation, and the impurity abutment blocking plate 852 rotates around the turning shaft 853 as the center to complete the impurity removal operation;

[0108] When the impurities are discharged at the final stage, and the impurities are not enough to move the baffle plate 852, the convex block 861 moves the moving rack 854 to contact the flip gear 855 and realize the rotation of the flip gear 855, thereby opening the baffle plate 852 to continue to discharge the impurities;

[0109] After the impurities are removed, the pneumatic assembly 5 is driven to move downward, and the push plate 84 is reset under the reset function of the torsion spring 833, and then the next refining process is realized.
