Description

Technical Field

[0001] The utility model relates to a high energy efficiency ratio transfer bag with excellent heat preservation effect. Background Art

[0002] At present, most of the short-distance transportation of molten aluminum at home and abroad is carried out in the form of transfer bags. When the molten aluminum is transported, the temperature drops greatly, about 20-50 degrees per 100 meters, so it needs to be insulated. Most of the transfer bags are transported by hoisting, using gantry cranes or cranes. In this mode of transportation, the transfer bag of this structure is heavy and inconvenient to transport; and during work, because the transfer bag cannot be fixed, it will shake, which is high risk and poses a huge safety hazard to practitioners.

[0003] The original pouring ladle has no insulation layer. After the molten aluminum is taken out of the furnace, the heat loss is large and the temperature drops quickly. In order to meet the casting temperature requirements of the molten aluminum, the temperature of the molten aluminum in the insulation furnace can only be increased. The existing insulation method is to use gas to heat the surface of the molten aluminum from top to bottom. This method has low thermal efficiency, high energy consumption, uneven heating, low bottom temperature, and the molten aluminum is easy to oxidize and absorb air, which affects the quality of the casting and is prone to cold material. The slag will agglomerate with the furnace wall, causing damage to the transfer ladle furnace body. Utility Model Content

[0018] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The device discloses a high energy efficiency transfer bag with excellent heat preservation effect. Compared with the existing transfer bag, which uses gas to heat the surface of molten aluminum from top to bottom in an inefficient way, the device uses electromagnetic induction to directly heat the furnace body, and then with a designed insulation layer, it can reduce heat loss, thus having the advantages of low energy consumption and high energy efficiency. The heating method is changed so that the molten aluminum in the furnace can maintain a relatively stable temperature from the bottom to the top, thereby avoiding the occurrence of cold materials and achieving the purpose of reducing material consumption.

[0020] Because the occurrence of cold material phenomenon is avoided, there will be no or only a small amount of slag in the furnace. And because the furnace body is heated by induction, the problem of slag agglomeration on the furnace wall will not occur, thereby improving the service life of the furnace body 3.

[0021] The device has excellent heating capacity, and the heating components are directly wound around the outer wall of the furnace body 3. Therefore, when transporting the same unit volume of molten aluminum, the transfer bag of the device is smaller in volume and lighter in weight. The cost of raw materials is reduced, and the processing difficulty is reduced.

[0022] See attached Figure 1 To Attachment Figure 4 As shown, the structure of the device is described in detail below. The transfer bag assembly 2 of the device includes an internal furnace body 3, a protective cover 4 arranged outside, and a bottom support 5 located at the bottom. A thermal insulation layer 33 is first designed on the outer wall of the furnace body 3, and then a coil 32 for induction heating is wound. After the coil 32 is energized, due to the principle of electromagnetic induction, the furnace body 3 made of metal is self-heated to increase the temperature, thereby keeping the aluminum liquid at a suitable temperature during transportation.

[0023] The bottom bracket 5 includes a bottom plate 51 for supporting the furnace body 3 and two support beams 52 arranged below the bottom plate 51. The support beam 52 is hollow so that a forklift can be inserted into the middle to lift the bottom bracket 5 for transportation. Compared with the existing transportation method, the present device adopts a simpler and more reliable forklift transportation method, which is fast and has fewer safety hazards.

[0024] The shield 4 is installed above the base 5 and covers the outside of the furnace body 3. The shield 4 includes a frame 41 and a partition 42 attached to the frame 41. A mounting hole 43 is provided at the lower part of the partition 42 for installing a fan, and an air hole 44 is provided at the upper part. The function of the fan is to blow low-temperature gas from the outside onto the coil for cooling; the air flow blows from the fan to the coil, upward along the outer wall of the furnace body, and finally leaves from the air hole 44.

[0025] An upper cover plate is arranged above the frame to cover the space between the top of the heat insulation plate and the outer wall of the furnace body, and at the same time prevent the furnace body from shaking relative to the frame.

[0026] The coil of the device is wound around the middle and lower part of the furnace body 3, because the heat is transmitted upward. In order to maximize the use of thermal energy, the coil 32 is wound around the lower part, and the generated heat is concentrated in the lower part, and then transmitted upward due to heat conduction.

[0027] The function of the partition 42 is to separate the furnace body 3 from the outside to avoid accidental scalding. There is a gap between the partition 42 and the furnace body 3, which can prevent the coil 32 from heating other objects close to the outer wall of the furnace body 3.

[0028] In addition, a furnace cover 21 is provided above the furnace body 3 of the device, and the furnace cover 21 can be covered during transportation to prevent aluminum liquid from splashing out. A plurality of lifting rings 22 are provided on the furnace cover 21, and the furnace cover 21 can be lifted by the hanger 1 at the starting point and when transported to the destination, so as to facilitate pouring in or out of aluminum liquid.

[0029] The furnace body 3 of the device is provided with a furnace nozzle 31, which protrudes outward and extends out of the vertical space where the partition 42 is located. The furnace nozzle 31 is provided to facilitate the control of the direction of the aluminum liquid during pouring.

[0030] The frame 41 of the device is a cylinder with a regular polygonal cross section, and each face of the cylinder is provided with the partition 42. Alternatively, the cross section of the frame 41 is circular, and the outer circumference is covered with an arc-shaped partition 42.

[0031] The partition plate 42 of the device is an epoxy plate, which has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good machinability.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view.
