Description

Technical Field

[0001] This utility model relates to the field of electric crucible furnace technology, and more specifically, to an energy-saving rotary electric crucible furnace. Background Technology

[0002] A crucible furnace is the simplest type of smelting equipment, mainly used for melting non-ferrous metals with relatively low melting points, such as copper, aluminum, and their alloys. In this type of furnace, the alloy is melted inside the crucible, and the heat is transferred to the furnace charge through the crucible. The furnace charge and combustion products do not come into direct contact, so the chemical composition of the alloy is almost unaffected by the furnace atmosphere, and the temperature of the molten alloy is relatively uniform.

[0003] For example, the existing patent CN202010884680.3 discloses a rotatable and tiltable crucible furnace. It points out that during metal smelting, operators typically manually move the molten metal into a mold. During this process, molten metal can splash onto the operator's body, posing a safety hazard. Furthermore, after the metal raw material is processed, it needs to be melted and held at a specific temperature in the crucible furnace before use. The traditional use of a single crucible furnace with a single furnace chamber has disadvantages: simultaneous melting and production results in large temperature fluctuations in the metal raw material within the furnace and crucible, leading to high impurity levels. For companies with high product quality requirements, the metal raw material cannot be degassed and slag removed in a timely manner, resulting in a high scrap rate.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an energy-saving rotary electric crucible furnace to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An energy-saving rotary electric crucible furnace includes a base and a furnace body. The furnace body is connected to the base via an adjustment mechanism. The adjustment mechanism includes two symmetrically arranged side frames. The side frames are close to each other and have mounting seats connected to the bottom of the furnace body. The top of the mounting seats has symmetrically arranged side plates on both sides. The side frames are far apart and have rotating shafts that are movably connected to the side frames.

[0008] Preferably, the adjustment mechanism includes a horizontal block located at the top of the side frame, and the top of the horizontal block is provided with a drive mechanism for driving the rotating shaft.

[0009] Preferably, the drive mechanism includes a housing, one end of the rotating shaft extends into the housing, a worm gear is fitted inside the housing, a worm is provided on the top of the worm gear and meshes with it, and one end of the worm is connected to the output end of the drive motor inside the housing.

[0010] Preferably, the bottom of the first side frame and the second side frame are provided with a base plate that is connected to the base, and the base plate is connected to the base by bolts.

[0011] Preferably, the base is movably connected to a chassis, and the top of the chassis is provided with a sliding groove for the base to rotate. The number of crucible furnace bodies is two.

[0012] Preferably, the base has a fixed shaft in the middle that is movably connected to the chassis, and the outer surface of the base has a toothed groove, and the top of the chassis has a gear that meshes with the toothed groove.

[0013] Preferably, the shaft of the gear is connected to the output end of the forward and reverse motor on the chassis.

[0014] The beneficial effects of this utility model are as follows: Through the design of the adjustment mechanism and the drive mechanism, the rotating shaft drives the crucible furnace body to rotate, thereby pouring the molten metal inside the crucible furnace body out from the inside and pouring the molten metal into the designated position. The automatic operation can reduce workers' contact with the crucible furnace body, reduce the occurrence of processing accidents when pouring molten metal, and improve protection performance. Moreover, the worm gear and worm have a self-locking function, which prevents the crucible furnace body from resetting itself, thereby improving the stability when pouring molten metal. The design of the chassis and the slide can drive the base to rotate circumferentially, so that the two sets of crucible furnace bodies can alternately melt and heat the molten aluminum.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] According to an embodiment of the present invention, an energy-saving rotary electric crucible furnace is provided.

[0023] Example 1;

[0024] like Figure 1-3 As shown, the energy-saving rotary electric crucible furnace according to an embodiment of the present invention includes a base 1 and a crucible furnace body 2. The crucible furnace body 2 is connected to the base 1 through an adjustment mechanism. The adjustment mechanism includes a side frame 1 3 and a side frame 2 symmetrically arranged. The side frame 1 3 and the side frame 2 4 that are close to each other are provided with a mounting seat 5 that is connected to the bottom of the crucible furnace body 2. The top two sides of the mounting seat 5 are provided with symmetrically arranged side plates 6. The side of the two sets of side plates 6 that are far apart from each other are provided with a rotating shaft 7 that is movably connected to the side frame 1 3 and the side frame 2 4.

[0025] Example 2;

[0026] like Figure 1-3 As shown, the adjustment mechanism includes a horizontal block 8 located at the top of the side frame 3. The top of the horizontal block 8 is provided with a drive mechanism for driving the rotating shaft 7. The drive mechanism includes a housing 9. One end of the rotating shaft 7 extends into the housing 9. A worm gear 10 is sleeved inside the housing 9. The top of the worm gear 10 is provided with a worm 11 that meshes with it. One end of the worm 11 is connected to the output end of the drive motor 12 inside the housing 9. The bottom of the side frame 3 and the side frame 4 is provided with a base plate 13 connected to the base 1. The base plate 13 is connected to the base 1 by bolts.

[0027] Example 3;

[0028] like Figure 1-3 As shown, a base 14 is movably connected to the bottom of the base 1. A groove for the base 1 to rotate is provided on the top of the base 1. There are two sets of crucible furnace bodies 2. A fixed shaft is provided in the middle of the base 1 and is movably connected to the base 14. A toothed groove 15 is provided on the outer surface of the base 1. A gear 16 that meshes with the toothed groove 15 is provided on the top of the base 14. The axis of the gear 16 is connected to the output end of the forward and reverse motor on the base 14.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In practical applications, when it is necessary to pour out the molten metal inside the crucible furnace body 2, the drive motor 12 is started to drive the worm gear 11 to rotate. Through the meshing transmission between the worm gear 11 and the worm wheel 10, the rotating shaft 7 is driven to rotate. The rotating shaft 7 drives the side plate 6, the mounting base 5, and the crucible furnace body 2 to rotate, thereby pouring out the molten metal inside the crucible furnace body 2. When one crucible furnace body 2 is used for melting, after melting, it is degassed, slag removed, and then rotated to the side of the equipment for production. At this time, the other crucible furnace body 2 can be driven by the forward and reverse motors to rotate the gear 16. The gear 16 meshes with the tooth groove 15 on the outer surface of the base 1 to rotate it 180°, so that it can continue to melt. The two are used alternately, so that they can melt alternately.

[0031] In summary, by utilizing the above-mentioned technical solution of this utility model, through the design of the adjustment mechanism and the drive mechanism, the rotating shaft 7 drives the crucible furnace body 2 to rotate, thereby pouring the molten metal inside the crucible furnace body 2 out from the inside and pouring the molten metal into the designated position. The automatic operation can reduce worker contact with the crucible furnace body 2, reduce processing accidents when pouring molten metal, and improve protection performance. Moreover, the worm gear 10 and the worm 11 have a self-locking function, which prevents the crucible furnace body 2 from resetting itself, thereby improving the stability when pouring molten metal. The design of the chassis 14 and the slide groove can drive the base 1 to rotate circumferentially, so that the two sets of crucible furnace bodies 2 can alternately melt and heat the molten aluminum.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
