DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0037] like Figure 1-Figure 7 As shown, the present invention provides a heat dissipation type smelting device for processing microalloyed low-oxygen copper rods, comprising a mounting frame 1, a heating assembly 2, a furnace assembly 4, a lifting assembly 6 and a stirring assembly 7;

[0038] The mounting frame 1 is used as a basic supporting structure, including a bottom plate 10, on which an arc-shaped slide housing 11 is provided, which is used to accommodate and guide the movement of the slider 40 of the furnace assembly 4, and a supporting frame 12 is also provided on the bottom plate 10, and a fixing frame 14 is provided on one side of the top of the supporting frame 12, which is used to install the second motor 63, and a second mounting plate 15 is provided on the top back of the supporting frame 12, and support arms 16 are symmetrically provided on both sides of the tail of the second mounting plate 15, and a pulley 17 is movably provided between the two supporting arms 16, which is used to guide the traction rope 31 of the traction device 3;

[0039] The heating assembly 2 is sleeved on the outside of the melting furnace assembly 4, and includes a ceramic insulation shell 20. The rotating shafts 22 symmetrically arranged on both sides of the outer wall of the ceramic insulation shell 20 are movably arranged on the support frame 12 through a pair of first bearing seats 23 so that it can rotate. The inner wall of the ceramic insulation shell 20 is provided with a resistance heating wire 21, and a material guide shell plate 24 is provided on one side of the top;

[0040] The furnace assembly 4 includes a slider 40 arranged in the arc-shaped chute shell 11, a bottom shell 41 is arranged on the top of the slider 40, a third mounting plate 43 is arranged on one side of the bottom shell 41, a handle 44 is arranged on the back of the third mounting plate 43, a motor 45 is arranged on the top, a gear 46 is arranged on the top of the transmission end of the motor 45, a movable groove 42 is opened on the bottom shell 41, a graphite crucible 47 is arranged above the bottom shell 41, and the graphite crucible 47 is movably arranged in the ceramic insulation shell 20, and casters 49 are arranged at the bottom of several supporting legs 48 below the outer wall, and the casters 49 are arranged in the movable groove 42, and the transmission teeth 411 on the outer driving ring 410 are meshed and connected with the gear 46, and the port of the arc-shaped chute shell 11 is symmetrically provided with card edges 18 on both sides to limit the movement range of the slider 40, and an electromagnetic induction heating device 5 is arranged on the top of the bottom shell 41, which is located below the graphite crucible 47;

[0041] The first mounting plates 13 symmetrically arranged on the inner walls of both sides of the support frame 12 are located above the rotating shaft 1 22. The lifting assembly 6 includes a pair of lead screws 60 movably arranged between the first mounting plates 13 and the top plate of the support frame 12 through a pair of second bearing seats 64. The sprocket wheels 61 symmetrically arranged on the upper ends of the two lead screws 60 are connected by a chain 62. The top of one of the lead screws 60 is connected to the transmission end of the second motor 63 arranged in the fixing frame 14.

[0042] The stirring assembly 7 includes a top cover 70, and the nuts 76 on the mounting ears 75 symmetrically arranged on both sides of the top cover 70 are threadedly arranged on the lead screw 60. After the transmission end of the motor 3 71 arranged on the top of the top cover 70 passes through the top cover 70, a pair of stirring frames 73 are symmetrically arranged on the rotating shaft 2 72 arranged on the top thereof, and a spiral stirring blade 74 is arranged between the two stirring frames 73.

[0043] Preferably, the slider 40 is made of wear-resistant and high-temperature resistant alloy material, and its surface is specially treated to have good hardness and wear resistance. It can slide frequently and for a long time in the arc-shaped slide slot shell 11 without being easily worn, thereby ensuring the smoothness and reliability of the movement of the furnace assembly 4.

[0044] When in use, the resistance heating wire 21 and the electromagnetic induction heating device 5 are first turned on to preheat the graphite crucible 47. During the preheating process, the processed copper and microalloy are precisely proportioned simultaneously;

[0045] After the preheating work is completed, the copper and microalloy with the correct proportion are placed in the graphite crucible 47, and then the power of the resistance heating wire 21 and the electromagnetic induction heating device 5 is increased. At the same time, the motor 45 is started, and the motor 45 drives the gear 46 to operate. The gear 46 drives the driving ring 410 to drive the plurality of casters 49 to rotate by meshing the transmission teeth 411, so that the graphite crucible 47 can be rotated, which makes the graphite crucible 47 evenly heated as a whole while further heating the graphite crucible 47;

[0046] After the copper and microalloy in the graphite crucible 47 are melted, the motor 2 63 can be started to rotate forward. The forward rotation of the motor 2 63 drives a lead screw 60 to rotate forward, and then the other lead screw 60 rotates synchronously through the cooperation of the sprocket 61 and the chain 62. At this time, the rotation of the two lead screws 60 drives the two screw nuts 76 to move downward synchronously, thereby driving the top cover 70 downward. When the top cover 70 completely covers the top of the graphite crucible 47, the motor 2 63 is turned off. Afterwards, the motor 3 71 can be turned on to drive the rotating shaft 2 72 to rotate, thereby prompting the stirring frame 73 and the spiral stirring blade 74 to stir the melt, which can not only fully mix the microalloy and copper components, but also avoid heat accumulation, disperse the heat, and make the heating more uniform;

[0047] Finally, when the smelting work is completed, the motor 2 63 is started in reverse to reverse the rotation, so that the stirring assembly 7 is raised and reset. Then, the charging barrel is placed in front of the device, and then the traction device 3 is started to reel in the traction rope 31. The traction rope 31 pulls the handle 44 through the hook 30, so that the slider 40 moves upward in the arc chute shell 11. The ceramic insulation shell 20 rotates around the rotating shaft 1 22 as the center under the inclination of the graphite crucible 47, so that the furnace assembly 4 is tilted as a whole, so that the molten liquid is poured out of the graphite crucible 47. The molten liquid will flow smoothly into the charging barrel along the guide shell plate 24.

[0048] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
