Description

Technical Field

[0001] The utility model relates to a transfer bag with a safety protection design. 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 packages.

[0003] Most of the transfer bags are transported by hoisting, using gantry cranes or cranes. In this mode of transportation, the transfer bags of this structure are heavy and inconvenient to transport; and during work, since the transfer bags cannot be fixed, they will shake, which is a high risk and poses a huge safety hazard to the practitioners.

[0004] In order to meet the casting temperature requirements of molten aluminum, the temperature needs to be maintained during transportation in the transfer bag. The existing transfer bag uses gas to heat the surface of the molten aluminum from top to bottom. This open flame working method also has very high risks.

[0005] To this end, it is necessary to design a safety protection measure for the transfer bag to reduce the risk. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a transfer bag with a safety protection design, changes the heating and heat preservation method, and sets a safety insulation board, and finally replaces the transportation method, thereby improving safety.

[0007] In order to solve the above technical problems, the utility model solves them through the following technical scheme: a transfer bag with a safety protection design, comprising a furnace body with an electromagnetic induction coil wound around the outer wall, a protective cover arranged outside the furnace body, and a base arranged at the bottom of the protective cover.

[0008] In the above technical solution, the shield is provided with a heat insulation board, and the heat insulation board surrounds the furnace body in the middle. Among them, if the heat insulation board is made of metal or non-insulating board, it is necessary to keep a safe distance from the coil to prevent the heat insulation board from being induced to heat. Therefore, the minimum distance between the heat insulation board and the coil is L, L=0.5P, where P is the coil power. If the heat insulation board is an insulating board, such as epoxy board, etc., there is no need to consider the safety distance.

[0009] In the above technical solution, the base includes a bottom plate for supporting the furnace body and two support beams arranged below the bottom plate; the support beams are hollow so as to facilitate forklift insertion for transportation.

[0010] In the above technical solution, the protective cover includes a frame, the heat insulation board is installed on the side of the frame, the heat insulation board is provided with a mounting hole at the bottom and a ventilation hole at the top, and a fan is provided at the mounting hole.

[0011] In the above technical solution, the frame is a column with a regular polygonal cross section, and the heat insulation board is arranged on each face of the column.

[0012] In the above technical solution, a furnace cover is arranged above the furnace body, and a plurality of hanging rings are arranged on the furnace cover.

[0013] In the above technical solution, a heat-insulating layer is arranged between the furnace body and the coil.

[0014] In the above technical solution, a furnace nozzle is arranged on the furnace body, and the furnace nozzle protrudes outwards and extends out of the vertical space where the heat insulation board is located.

[0015] The utility model provides a transfer bag with a safety protection design, which cancels the temperature rise and heat preservation method of open flame heating and adopts the induction heating method of electromagnetic coil instead, thereby greatly reducing the safety risk; a protective shield is arranged on the transfer bag for heat insulation to prevent people from getting close and being accidentally scalded; finally, a heat insulation board is arranged to safely isolate the coil from the outside world to prevent other nearby parts from heating up under the influence of the electromagnetic induction coil.

[0021] 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.

[0022] See attached Figure 1 To Attachment Figure 3 As shown, the structure of the device is described in detail below. The device includes a furnace body 1 with an electromagnetic induction coil 2 wound around the outer wall, a shield is arranged outside the furnace body 1, and a bottom support 4 is arranged at the bottom of the shield. The coil 2 of the device makes the furnace body 1 made of metal material self-heat under the principle of electromagnetic induction to increase the temperature, so as to keep the aluminum liquid contained at a suitable temperature during transportation. The device adopts electromagnetic induction heating, thereby removing the existing gas heating method, eliminating open flames, and improving safety. In addition, the gas heating method has a large structure, resulting in a very heavy weight of the transfer bag and inconvenient transportation. The heating method is changed, so that the aluminum liquid in the furnace is heated from the bottom to the top, and a relatively stable temperature can be maintained, thereby avoiding the occurrence of cold materials and achieving the purpose of reducing material consumption. Because the occurrence of cold materials is avoided, there will be no or only a small amount of slag in the furnace. Because the furnace body 1 is heated by induction, the problem is higher than the aluminum liquid contained, so there will be no problem of slag agglomeration on the furnace wall, thereby improving the service life of the furnace body 1.

[0023] A shield is provided outside the transfer bag to insulate heat, so as to prevent accidental burns to personnel. At the same time, the shield and the base 4 cooperate to fix the transfer bag. During transportation, the entire transfer bag assembly 10 can be transported by a forklift.

[0024] The shield is provided with a heat insulation board, and the heat insulation board surrounds the furnace body 1 in the middle.

[0025] When the electromagnetic induction coil is working, it is not directional, but will have an effect on the surrounding area. It is necessary to prevent other objects from getting too close to it and being heated by the coil.

[0026] If the heat insulation board is made of metal or non-insulating board, it is necessary to maintain a safe distance from the coil to prevent the heat insulation board from being induced to heat. It is necessary to set a minimum spacing L to ensure safety. Objects outside the minimum spacing L will not be affected by the coil and will not heat up significantly, thus avoiding accidents. According to actual research and development results, the minimum spacing L is related to the working power of the coil. The specific correlation formula is: L=0.5P, where L is in cm and P is in kw. For example, when the power of the coil is 30kw, the minimum spacing L to ensure safety is 15cm. This device sets a heat insulation board at the minimum spacing, and objects outside the heat insulation board will not be affected by the coil and will not heat up significantly.

[0027] If the heat insulation board is an insulating board, such as an epoxy board, there is no need to consider the safety distance, as it will not be heated by the coil. The epoxy board has good heat resistance and moisture resistance, and can separate the furnace body 1 from the outside world to avoid accidental burns. In addition, in order to prevent other non-insulating board materials outside the heat insulation board from being heated, the same safety distance can also be set for the insulation board. Because there is a gap between the heat insulation board and the furnace body 1, this can prevent the coil 2 from heating other objects close to the outer wall of the furnace body 1.

[0028] In addition, epoxy boards also have high mechanical and dielectric properties, and good machinability, making them easy to produce and process.

[0029] The bottom bracket 4 includes a bottom plate 41 for supporting the furnace body 1 and two support beams 42 arranged below the bottom plate 41. The support beam 42 is hollow so that a forklift can be inserted into the middle to lift the bottom bracket 4 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.

[0030] The shield of the device includes a frame, which is installed above the base 4 and is covered outside the furnace body 1. The heat insulation board is installed on the side of the frame. The lower part of the heat insulation board is provided with a mounting hole for installing a fan, and the upper part is provided with an air vent. The function of the fan is to blow the 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 vent 44.

[0031] 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.

[0032] In this device, a heat-insulating layer 11 is provided between the furnace body 1 and the coil 2, which further improves the thermal efficiency and indirectly improves the safety.

[0033] The coil 2 of the device is wound around the middle and lower part of the furnace body 1, because the heat is transferred upward. In order to maximize the use of heat energy, the coil 2 is wound around the lower part, and the generated heat is concentrated in the lower part, and then transferred upward due to heat conduction.

[0034] In addition, a furnace cover 5 is provided above the furnace body 1 of the device, and the furnace cover 5 can be covered during transportation to prevent aluminum liquid from splashing out. A plurality of lifting rings 51 are provided on the furnace cover 5, and the furnace cover 5 can be lifted by a hanger 6 at the starting point and when transported to the destination, so as to facilitate pouring in or pouring out aluminum liquid. A furnace nozzle is provided on the furnace body 1 of the device, and the furnace nozzle protrudes outward and extends out of the vertical space where the heat insulation board is located. This arrangement makes it convenient to control the direction of aluminum liquid when pouring, thereby preventing workers from being scalded.

[0035] In addition, the frame of the device is a cylinder with a regular polygonal cross section, and the heat insulation board is arranged on each face of the cylinder. Alternatively, the cross section of the frame is circular, and the outer circumference is covered with an arc-shaped heat insulation board.
