[0003] During the smelting process, there will be aluminum ash of aluminum oxide on the surface of the aluminum liquid. If these aluminum ash is not removed, it will cause the strength and toughness of the parts to decrease during the process of making aluminum alloy from aluminum liquid in the later period.

[0037] In the specific operation process, first, the recovery container is placed in front of the furnace door of the aluminum melting furnace, then the operator enters the inside of the control room 11, and moves the vehicle body 1 in front of the furnace door through the control room 11, then opens the furnace door, and then starts the first cylinder 2 and the second cylinder 21 through the control room 11, drives the load frame 22 to pop out through the first cylinder 2 and the second cylinder 21, and drives the load cylinder 3 to pop out through the load frame 22, drives the first electric telescopic rod 33 to pop out through the load cylinder 3, drives the first extension frame 34, the support plate 35 and the slagging plate 36 to pop out through the first electric telescopic rod 33, and drives the second extension frame 63, the extrusion plate 64 and the edge 65 to pop out through the second electric telescopic rod 62, thereby ensuring that the extrusion plate 64 and the slagging plate 36 correspond to the height of the furnace door;

[0038] Then control the first electric telescopic rod 33 to start through the control room 11, and the first electric telescopic rod 33 pops out towards the furnace pool after starting, and in the process of popping out, the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to move towards the furnace pool, and the support plate 35 drives the slagging plate 36 to move towards the furnace pool;

[0039] Then control the first cylinder 2 to return, so that the load frame 22 is limited by the second cylinder 21 and pulled by the first cylinder 2, so that the load frame 22 drives the load cylinder 3 to tilt towards the furnace pool, so that the load cylinder 3 drives the first electric telescopic rod 33, the first extension frame 34 and the support plate 35 to tilt towards the furnace pool, so that the support plate 35 drives the slagging plate 36 to enter the aluminum liquid in the furnace pool, and then the first electric telescopic rod 33 is controlled to return through the control room 11, and the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to return, and the support plate 35 drives the slagging plate 36 to return, and the slagging plate 36 performs slagging operation on the aluminum ash in the aluminum liquid in the process of returning, so that the aluminum ash is gradually close to the furnace door under the driving of the slagging plate 36;

[0040] Specifically, in the process of returning and slagging of the slagging plate 36, the second electric telescopic rod 62 is started through the control room 11, so that the second electric telescopic rod 62 drives the second extension frame 63 to move towards the direction of the slagging plate 36, so that the second extension frame 63 drives the extrusion plate 64 and the edge 65 to move towards the direction of the slagging plate 36, until the extrusion plate 64 drives the edge 65 to be clamped into the inside of the slagging plate 36, so that the slagging plate 36 is wrapped with the aluminum ash scraped away by the slagging plate 36 under the cooperation of the extrusion plate 64 and the edge 65;

[0041] After the aluminum dregs are wrapped by the dregs scraping plate 36, the extrusion plate 64 and the edge 65, the first cylinder 2 is controlled to be ejected and restored to the state of being flush with the second cylinder 21, and then the load frame 22 is controlled to be restored to the horizontal state, so that the load frame 22 drives the load cylinder 3 to be restored to the horizontal state, so that the load cylinder 3 drives the first electric telescopic rod 33 and the second electric telescopic rod 62 to be restored to the horizontal state, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to be restored to the horizontal state, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the dregs scraping plate 36 to be restored to the horizontal state, thereby making the dregs scraping plate 36, the extrusion plate 64 and the aluminum dregs separate from the aluminum liquid;

[0042] Further, after the dregs scraping plate 36, the extrusion plate 64 and the aluminum dregs separate from the aluminum liquid, the first electric telescopic rod 33 and the second electric telescopic rod 62 are controlled to be retracted synchronously, so that the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the dregs scraping plate 36 to be retracted synchronously, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to be retracted synchronously, so that the dregs scraping plate 36 and the extrusion plate 64 drive the aluminum dregs to move towards the direction of the recovery container, and after the dregs scraping plate 36 and the extrusion plate 64 move above the recovery container, the second electric telescopic rod 62 is controlled to be retracted alone, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to be retracted, and during the retraction of the extrusion plate 64, the closed state with the dregs scraping plate 36 is released, that is, the aluminum dregs wrapped by the dregs scraping plate 36 and the extrusion plate 64 can directly fall into the recovery container.

[0043] It should be noted that the dregs scraping plate 36 and the extrusion plate 64 are cuboids, and the initial state of the first extension frame 34 and the dregs scraping plate 36 is horizontal, which is used to cooperate with the furnace door of the rectangular aluminum melting furnace, so that the amount of dregs scraped by the dregs scraping plate 36 is maximized.

[0044] Embodiment two:

[0045] The motor 23 is fixed inside one side of the load frame 22, the motor 23 is controlled by the control chamber 11, the output shaft of the motor 23 is fixed with the load cylinder 3, the end of the dregs scraping plate 36 away from the control chamber 11 is fixed with the flow guide frame 4, the end of the dregs scraping plate 36 close to the control chamber 11 is fixed with the filtrate plate 5, the surface of the filtrate plate 5 is provided with filter holes, the surface of the extrusion plate 64 close to one end of the flow guide frame 4 is fixed with the flow guide plate 7, the bottom length of the flow guide frame 4 is longer than the bottom length of the flow guide plate 7, and the top point of the flow guide frame 4 is higher than the top point of the flow guide plate 7;

[0046] In the specific operation process, on the basis of example one, when the extrusion plate 64 and the edge 65 are clamped into the inside of the residue scraping plate 36 and drive the aluminum ash away from the surface of the aluminum liquid, the motor 23 can be started through the control chamber 11, the load cylinder 3 is driven to rotate through the motor 23, and then the load cylinder 3 drives the first electric telescopic rod 33 and the second electric telescopic rod 62 to rotate synchronously to the vertical state, the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the residue scraping plate 36 to rotate synchronously to the vertical state, the second electric telescopic rod 62 drives the second extension frame 63, the extrusion plate 64 and the edge 65 to rotate synchronously to the vertical state, and the flow guide frame 4 is rotated to the upper side of the filtrate plate 5;

[0047] Specifically, after the residue scraping plate 36 and the extrusion plate 64 are rotated to the vertical state, the aluminum ash is located above the filtrate plate 5, and then the aluminum liquid mixed in the aluminum ash is filtered out under the filtration of the filtrate plate 5 and falls into the aluminum liquid of the furnace pool again, thereby reducing the time of the aluminum ash entering the aluminum ash refining machine for refining the aluminum liquid in the subsequent period;

[0048] Further, during the filtration of the aluminum liquid, the motor 23 can be controlled to continuously reverse or rotate in one direction, so that the aluminum ash repeatedly slides under the wrapping of the residue scraping plate 36, the extrusion plate 64 and the edge 65, and in the sliding process, the filtration effect of the aluminum liquid is improved, the time and energy consumption of the aluminum ash for refining the aluminum liquid in the later period are further reduced, and the process is carried out in the molten aluminum furnace, without worrying about dust raising and aluminum liquid spatter;

[0049] When the aluminum liquid is filtered, the first electric telescopic rod 33 and the second electric telescopic rod 62 can be controlled to return through the control chamber 11, the first electric telescopic rod 33 drives the first extension frame 34, the support plate 35 and the residue scraping plate 36 to return, the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return, the residue scraping plate 36 and the extrusion plate 64 drive the aluminum ash to move synchronously towards the direction of the recovery container, and the residue scraping plate 36 and the extrusion plate 64 stop above the recovery container, at this time, the motor 23 drives the load cylinder 3 to overturn, the load cylinder 3 drives the residue scraping plate 36 and the extrusion plate 64 to overturn, and the filtrate plate 5 is located above the flow guide frame 4, then the first air cylinder 2 and the second air cylinder 21 are controlled to return, the load frame 22 moves towards the recovery container, the load frame 22 drives the load cylinder 3 to move towards the recovery container, and then under the linkage of the load cylinder 3, the extrusion plate 64 and the residue scraping plate 36 enter the inside of the recovery container;

[0050] At this time, according to the operation steps of the embodiment, the second electric telescopic rod 62 is controlled to return, so that the second electric telescopic rod 62 drives the second extension frame 63 to return, so that the second extension frame 63 drives the extrusion plate 64 and the edge plate 65 to separate from the slag plate 36, so that the extrusion plate 64 and the slag plate 36 are in the closed state, so that the filtered aluminum ash can directly enter the recovery container, and the splash and dust generated when the aluminum ash enters the recovery container are reduced under the blocking of the recovery container, the slag plate 36 and the extrusion plate 64, and the waste of molten aluminum is reduced.

[0051] It should be noted that when facing the cylindrical molten aluminum furnace, when the furnace door of the cylindrical molten aluminum furnace is larger than the area of the filter plate 5, according to the operation steps of the embodiment, the first air cylinder 2 and the second air cylinder 21 are started at the same time, the load frame 22 is ejected, and the load cylinder 3 is adjusted in height to ensure that the load cylinder 3 drives the first electric telescopic rod 33, the first extension frame 34, the support plate 35 and the slag plate 36 to be higher than the cylindrical molten aluminum furnace, and then the first electric telescopic rod 33 is controlled to start alone, so that the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to move towards the cylindrical molten aluminum furnace, so that the support plate 35 drives the slag plate 36 to move above the cylindrical molten aluminum furnace;

[0052] Then, the motor 23 is controlled to start, so that the motor 23 drives the load cylinder 3 to rotate, and then the load cylinder 3 drives the slag plate 36 to rotate to the vertical state, at this time, by controlling the rotation angle of the motor 23, the flow guide frame 4 is located above the filter plate 5, and then the first air cylinder 2 and the second air cylinder 21 are controlled to return at the same time, so that the first air cylinder 2 and the second air cylinder 21 drive the load frame 22 to return and descend, so that the load frame 22 drives the load cylinder 3 to descend, and then the load cylinder 3 drives the slag plate 36 to descend, and the slag plate 36 drives the filter plate 5 to descend and enter the inside of the cylindrical molten aluminum furnace;

[0053] When the filter plate 5 enters the inside of the cylindrical molten aluminum furnace, the aluminum ash inside can be salvaged, and the molten aluminum in the aluminum ash is filtered out during the salvaging process, and then the first electric telescopic rod 33 is controlled to return, and then the first electric telescopic rod 33 drives the first extension frame 34 and the support plate 35 to return, and the support plate 35 drives the slag plate 36 and the filter plate 5 to return, after the slag plate 36 and the filter plate 5 are moved to the above of the recovery container, the second air cylinder 21 is controlled to return, so that the load frame 22 is inclined towards the direction of the second air cylinder 21, and then the end of the load frame 22 close to the slag plate 36 is lifted, and then the slag plate 36 drives the filter plate 5 to incline towards the direction of the second air cylinder 21, so that the aluminum ash salvaged on the surface of the filter plate 5 can enter the recovery container, thereby improving the versatility of the present application, and without turning over the cylindrical molten aluminum furnace to cooperate with the salvaging, the salvaging efficiency of the aluminum ash is improved.

[0054] Example three:

[0055] The inner side of the edge 65 close to the guide frame 4 is fixed with a positioning rod 66, the outer side of the positioning rod 66 is fixed with a plurality of limiting blocks 67, the outer side of the positioning rod 66 is rotatably connected with a plurality of material loosening rods 68, and each material loosening rod 68 is located on the inner side of a group of limiting blocks 67, and the inner wall of the edge 65 located below the material loosening rod 68 is fixed with a limiting rod 69;

[0056] In the specific operation process, on the basis of example one, when the extrusion plate 64 and the edge 65 are clamped into the inside of the first extension frame 34, the material loosening rod 68 is inclined under the guidance of the guide frame 4, and then the material loosening rod 68 enters the inside of the slag scraping plate 36 and the extrusion plate 64 in an inclined state, and when the slag scraping plate 36 and the extrusion plate 64 are completely closed, the guide frame 4 abuts against the guide plate 7;

[0057] Subsequently, the control chamber 11 controls the motor 23 to start, the control motor 23 drives the load cylinder 3 to overturn, the load cylinder 3 links the slag scraping plate 36 and the extrusion plate 64 to overturn, and the guide frame 4 is located below the filtrate plate 5, and when it is needed to put the aluminum ash into the recovery container, the control chamber 11 controls the second electric telescopic rod 62 to return alone, so that the second electric telescopic rod 62 drives the second extension frame 63 and the extrusion plate 64 to return, and the extrusion plate 64 drives the edge 65 to return;

[0058] During the return process of the extrusion plate 64 and the edge 65, the guide frame 4 and the guide plate 7 gradually move away, so that the guide frame 4 and the guide plate 7 are in a state of being disengaged, that is, the slag scraping plate 36 and the extrusion plate 64 are in a state of being disengaged, and then the interval gap between the guide frame 4 and the guide plate 7 serves as a discharge port, so that the aluminum ash can fall into the inside of the recovery container through the interval gap between the guide frame 4 and the guide plate 7;

[0059] During the aluminum ash discharging process, the second electric telescopic rod 62 is controlled to be repeatedly and slightly ejected and returned, so that the extrusion plate 64 drives the guide plate 7 to repeatedly move back and forth in the inside of the slag scraping plate 36, and during the back and forth movement, the interval between the guide frame 4 and the guide plate 7 changes repeatedly, thereby avoiding the aluminum ash from being blocked in the gap between the guide frame 4 and the guide plate 7, and ensuring the smoothness of the aluminum ash discharging;

[0060] At the same time, with the repeated movement of the extrusion plate 64 in the inside of the slag scraping plate 36, the extrusion plate 64 drives the positioning rod 66 and the material loosening rod 68 to move repeatedly in the inside of the slag scraping plate 36, and the material loosening rod 68 deflects repeatedly along the inclined surface of the guide frame 4 under the pressure of the aluminum ash and its own gravity, thereby further ensuring the smoothness of the aluminum ash discharging;

[0061] Further, when the distance between the guide frame 4 and the guide plate 7 changes repeatedly, the loose material rod 68 is located above the distance between the guide frame 4 and the guide plate 7, which hinders the discharge of aluminum ash, reduces the speed of the discharge of aluminum ash, in turn reduces the potential energy of the falling of aluminum ash, and further reduces the impact force of the aluminum ash into the recycling container, thereby reducing the probability of splashing of molten aluminum and dust generation.

[0062] It should be noted that the height limiting rod 69 as a limiting structure limits the loose material rod 68, ensuring that the loose material rod 68 will not be clamped outside the slagging plate 36 when the slagging plate 36 and the extrusion plate 64 are clamped.
