Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy production, in particular to an aluminum alloy smelting and converter mechanism. Background Art

[0002] The smelting furnace and holding furnace in the aluminum alloy processing industry must convert the aluminum liquid (i.e. transfer the aluminum liquid from the smelting furnace to the holding furnace) and draw the aluminum liquid out of the holding furnace for casting during production. The entire process requires pouring out the aluminum liquid. Usually, the protective door of the smelting room is opened first, and then the smelting furnace and the holding furnace are rotated to pour out the aluminum liquid. Such operation steps are cumbersome and not conducive to the rapid transfer of aluminum liquid. When the smelting furnace and the holding furnace are rotated and poured out, once there is a lot of aluminum liquid inside, the aluminum liquid will flow out from the higher position of the top of the smelting furnace and the holding furnace. The impact of the aluminum liquid flowing out is large, which is prone to safety accidents and splashing and overflowing of the aluminum liquid. For this reason, we have introduced an aluminum alloy smelting and converter mechanism. Summary of the invention

[0034] 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.

[0035] See also Figure 1-11 , the present invention provides a technical solution:

[0036] Embodiment 1:

[0037] An aluminum alloy smelting and converter mechanism comprises a smelting room 1, wherein a smelting converter 8 and a heat preservation converter are arranged inside the smelting room 1. In the smelting converter 8, the aluminum alloy is first smelted into liquid, and the element content is detected. If the content is too low, trace elements are added, and if the content is too high, aluminum ingots are added. Qualified liquid enters the heat preservation converter. Therefore, the smelting mechanism is a continuous furnace, which is divided into two left and right furnaces. The right side is mainly for smelting, and the left side is mainly for heat preservation and storage. When in use, the liquid in the heat preservation furnace flows into a casting tank for casting, and then is used to manufacture aluminum plates for new energy vehicles.

[0038] Supports are provided on both sides of the smelting converter 8 and the insulation converter, and the rotating shafts 82 on both sides of the smelting converter 8 and the insulation converter are connected to the gear drive mechanism inside the support;

[0039] The gear drive mechanism includes two groups of driven gears 10 movably connected to the support through the gear shaft and a driving gear 9 meshed with the upper part between the two groups of driven gears 10;

[0040] When the motor 15 drives the rotating shaft 82, the driving gear 9 and the smelting converter 8 or the motor 15 drives the rotating shaft 82, the driving gear 9 and the insulation converter to rotate clockwise, the front and rear two sets of driven gears 10 can support the smelting converter 8 and the insulation converter through the driving gear 9.

[0041] A furnace body support ring 83 is fixed to the outer side of the smelting converter 8 and the heat-insulating converter, a rotating shaft 82 is fixed on the furnace body support ring 83 , and a driving gear 9 is fixed to the rotating shaft 82 .

[0042] The corresponding rotating shaft 82 passes through the driving gear 9 and the support and is connected to the motor shaft at the output end of the motor 15, and the motor 15 is fixed on the support.

[0043] The support is provided with a horizontal through groove for slidingly connecting the rack 11 , and the bottoms of the two sets of driven gears 10 extend into the horizontal through groove and then mesh with the upper end of the rack 11 .

[0044] The bottom of the gear drive mechanism is meshed with a rack 11 that is slidably connected to the inside of the support, and the rear end of the rack 11 is connected to a lifting protection door 2 provided at the opening 6 at the front end of the smelting room 1 through a guide wheel rope mechanism;

[0045] like Figure 2-3 As shown, the guide wheel rope mechanism includes a first guide wheel 12 movably connected inside the smelting room 1, a second guide wheel 13 movably connected and located below the first guide wheel 12, a third guide wheel 14 movably connected and located in front of the second guide wheel 13, a fourth guide wheel 17 movably connected and located in front of the top of the recessed window 3, a fifth guide wheel 18 movably connected inside the smelting room 1 and located behind the fourth guide wheel 17, a sixth guide wheel 16 movably connected and located below the fifth guide wheel 18, and a steel wire rope 5 fixedly connected to the rear end of the rack 11;

[0046] The steel wire rope 5 is fixedly connected to the top of the lifting protection door 2 after passing through the first guide wheel 12, the second guide wheel 13, the third guide wheel 14, the sixth guide wheel 16, the fifth guide wheel 18 and the fourth guide wheel 17 in sequence.

[0047] The front and rear driven gears 10 rotate counterclockwise, thereby driving the rack 11 to move forward in the horizontal through slot, and the lifting protection door 2 is pulled up through the wire rope 5 to leak out of the opening 6;

[0048] like Figure 1 ,2 As shown in FIGS. 3 and 5 , two groups of openings 6 are provided, and the openings 6 are respectively facing the front of the smelting converter 8 and the insulation converter. The openings 6 are located at the bottom of the recessed window 3 at the front end of the smelting room 1, and both sides of the lifting protection door 2 are slidably connected to the slide grooves 4 on the sides of the recessed window 3.

[0049] The upper and lower ends of both sides of the lifting protection door 2 are connected with extended protruding arms 201, and a roller 203 is movably installed in the U-shaped slot 202 at the end of the extended protruding arm 201 through a wheel axle. The extended protruding arm 201 is slidably connected in the slide groove 4, so that the roller 203 is close to the inner wall of the slide groove 4.

[0050] Such a configuration allows the lifting protection door 2 to remain smooth and stable when moving up and down, and when the tops of the smelting converter 8 and the insulation converter enter the transition trough 7 and are supported on the front baffle 72, the transition trough 7 installed on the lifting protection door 2 supports the tops of the smelting converter 8 and the insulation converter. This prevents the tops of the smelting converter 8 and the insulation converter from tilting excessively, thereby preventing the molten aluminum alloy liquid inside the smelting converter 8 and the insulation converter from flowing out;

[0051] like Figure 5 , 6 As shown in Figures 10 and 11, the rear end of the lifting protection door 2 is fixed with a transition material trough 7 through a liftable connecting piece, and the liftable connecting piece includes two groups of vertical connecting seats 206 fixed to the rear end of the lifting protection door 2, a T-shaped block 205 sliding in the T-shaped groove 208 inside the vertical connecting seat 206, a first spring 204 arranged at the bottom of the T-shaped groove 208 for supporting the T-shaped block 205, and an end cover 207 fixed on the top of the vertical connecting seat 206.

[0052] The front end of the T-shaped block 205 extends out of the T-shaped slot 208 and is connected to the transition material receiving slot 7. A rear baffle 71 is provided at the rear end of the transition material receiving slot 7, and a front baffle 72 is provided at the middle of the front end of the transition material receiving slot 7.

[0053] After the top of the smelting converter 8 and the insulation converter enter the transition receiving trough 7, the abutment plate 81 is located on the inner side of the front baffle 72, which can prevent the top of the smelting converter 8 and the insulation converter from being out of contact with the transition receiving trough 7, and avoid the molten aluminum alloy liquid from being unable to be poured into the transition receiving trough 7 due to excessive rotation of the smelting converter 8 and the insulation converter;

[0054] When the tops of the smelting converter 8 and the insulation converter just enter the transition receiving trough 7, the inclination of the smelting converter 8 and the insulation converter is insufficient to pour out most of the molten aluminum alloy liquid inside the smelting converter 8 and the insulation converter. At this time, the smelting converter 8 and the insulation converter need to continue to rotate clockwise;

[0055] As the smelting converter 8 and the holding converter continue to rotate clockwise, the tops of the smelting converter 8 and the holding converter press down the transition trough 7, causing the height of the transition trough 7 to decrease. At this time, the T-shaped block 205 connected to the transition trough 7 moves downward along the T-shaped slot 208, and the first spring 204 is in a compressed state until the inclination of the smelting converter 8 and the holding converter is sufficient, so that most of the molten aluminum alloy liquid inside the smelting converter 8 and the holding converter is poured into the transition trough 7;

[0056] After the smelting converter 8 and the heat-insulating converter rotate counterclockwise to reset, the first spring 204 exerts an elastic force on the T-shaped block 205, so that the T-shaped block 205 moves upward along the T-shaped slot 208, thereby realizing the upward movement and reset of the transition trough 7;

[0057] Since the T-shaped block 205 moves up and down along the T-shaped groove 208, the transition material receiving groove 7 moves up and down smoothly and stably.

[0058] A discharge hopper 73 is provided in the middle of the lower end of the transition receiving trough 7, and a sealing plate mechanism is provided in the discharge hopper 73, and the sealing plate mechanism is used to achieve the sealing of the discharge hopper 73;

[0059] The sealing plate mechanism includes two sets of opening and closing plates 74 symmetrically arranged inside the discharge hopper 73, and one side of the opening and closing plate 74 is movably connected to a groove 78 on the inner wall of the discharge hopper 73 through a connecting shaft 76. A second spring 77 located on the inner side of the connecting shaft 76 is also provided in the groove 78, and the top of the second spring 77 is connected to the lower end of the opening and closing plate 74; abutting ear plate 75 is provided at the top of the front end of the opening and closing plate 74.

[0060] like Figure 7 As shown, in the initial state, the opening and closing plates 74 are subjected to the elastic force of the second spring 77, and the two groups of opening and closing plates 74 rotate upward to a horizontal state, so that the two groups of opening and closing plates 74 seal the discharge hopper 73, so that after the smelting converter 8 and the insulation converter rotate clockwise, the transition receiving trough 7 can pre-accept the molten aluminum alloy liquid flowing out from the top of the smelting converter 8 and the insulation converter;

[0061] Until the top of the smelting converter 8 and the insulation converter enter the transition trough 7, Fig. 9 As shown, after the abutting plate 81 abuts against the upper end between the two sets of abutting ear plates 75, the abutting ear plates 75 drive the opening and closing plates 74 to rotate with the connecting shaft 76 as the center, so that the two sets of opening and closing plates 74 are in an open state, so that the molten aluminum alloy liquid in the transition trough 7 can be discharged through the discharge hopper 73;

[0062] By setting the transition trough 7, it is avoided that when there is a lot of molten aluminum alloy liquid inside the smelting converter 8 and the insulation converter, the smelting converter 8 and the insulation converter just start to rotate clockwise (such as Fig.10 position), so that the molten aluminum alloy flows out from a higher height position;

[0063] In this way, the molten aluminum alloy liquid can be first received by the transition receiving trough 7, and then discharged through the discharge hopper 73 at the bottom of the transition receiving trough 7, thereby reducing the height from which the molten aluminum alloy liquid flows out, thereby preventing the molten aluminum alloy liquid from flowing out from a higher height position, and preventing the molten aluminum alloy liquid from overflowing due to the huge impact force when entering the transfer trough 19.

[0064] After the gear drive mechanism drives the smelting converter 8 and the insulation converter to rotate clockwise, the rack 11 pulls up the lifting protection door 2 through the guide wheel rope machine and leaks out of the opening 6, and the tops of the smelting converter 8 and the insulation converter enter into the transition trough 7, and the transition trough 7 supports the tops of the smelting converter 8 and the insulation converter. At the same time, the abutment plate 81 on the tops of the smelting converter 8 and the insulation converter abuts against the sealing plate mechanism in the discharge hopper 73, so that the sealing plate mechanism opens, and the smelting converter 8 and the insulation converter pour the molten aluminum alloy liquid into the transition trough 7, and the molten aluminum alloy liquid is discharged through the discharge hopper 73.

[0065] Specifically, when in use, when the motor 15 drives the rotating shaft 82, the driving gear 9 and the smelting converter 8 or the motor 15 drives the rotating shaft 82, the driving gear 9 and the heat-insulating converter to rotate clockwise, the front and rear two sets of driven gears 10 rotate counterclockwise, thereby driving the rack 11 to move forward in the horizontal through groove, and the lifting protection door 2 is pulled up through the wire rope 5 to leak out of the opening 6;

[0066] At this time, the forklift 20 can move the transfer chute 19 into the smelting room 1 through the opening 6, so that the transfer chute 19 is located directly below the discharge hopper 73;

[0067] At the same time, after the top of the smelting converter 8 and the insulation converter enter the transition receiving trough 7, the molten aluminum alloy liquid in the smelting converter 8 and the insulation converter enters the transition receiving trough 7, and as the abutting plate 81 abuts against the upper end between the two sets of abutting ear plates 75, the abutting ear plates 75 drive the opening and closing plates 74 to rotate with the connecting shaft 76 as the center of the circle, so that the two sets of opening and closing plates 74 are in an open state, so that the molten aluminum alloy liquid in the transition receiving trough 7 can be discharged through the discharge hopper 73 and then fall into the transfer trough 19;

[0068] Then the forklift 20 moves the transfer tank 19 out of the smelting room 1;

[0069] When the motor 15 drives the rotating shaft 82, the driving gear 9 and the smelting converter 8 or the motor 15 drives the rotating shaft 82, the driving gear 9 and the heat-insulating converter to rotate counterclockwise, the rack 11 moves backward in the horizontal through groove and resets, and the rack 11 no longer tightens the wire rope 5. At this time, under the action of the gravity of the lifting protection door 2, the lifting protection door 2 blocks the opening 6 after it descends, thereby improving safety.

[0070] After the smelting converter 8 and the insulation converter rotate counterclockwise, the abutment plates 81 thereon no longer abut against the abutment ear plates 75. At this time, under the elastic force of the second spring 77, the two sets of opening and closing plates 74 rotate upward to a horizontal state, thereby achieving re-sealing of the discharge hopper 73 by the two sets of opening and closing plates 74.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
