Description

Technical Field

[0001] The utility model relates to the technical field of material metallurgy, in particular to a heat-insulating ladle structure for cast iron pieces. Background Art

[0002] Casting is a metal heat treatment process that humans mastered relatively early. Casting is a method of pouring liquid metal into a casting cavity that adapts to the shape of the part, and then waiting for it to cool and solidify to obtain a part or blank. Ladles are used for pouring operations in the foundry. After receiving the molten metal in front of the furnace, they are transported to the casting mold by a crane for pouring. There are many types of ladles, including iron ladles, steel ladles, teapot ladles, and ductile iron ladles.

[0003] However, according to the common ladle insulation structure on the market, generally only simple lightweight refractory bricks are set inside the cylinder as an insulation layer, which provides limited heat resistance and cannot effectively reduce the rate of heat conduction from the inside of the ladle to the outside, resulting in the molten iron being prone to temperature loss during transportation and waiting. At the same time, it is also unable to prevent the external environment from cooling the ladle. In summary, the temperature of the molten metal drops, which in turn affects the quality of the casting and the casting efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the single insulation layer of the traditional ladle has poor insulation effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an insulating ladle structure for cast iron parts, including a ladle cylinder, the inner wall of the ladle cylinder is provided with a high-temperature resistant lining layer, the outer wall of the high-temperature resistant lining layer is fixedly installed with a first insulating layer, the outer wall of the first insulating layer is fixedly installed with a plurality of fan-shaped vertical cylinders, the outer wall of the fan-shaped vertical cylinders is fixedly installed with a second insulating layer, and the outer wall of the second insulating layer is fixedly installed with an outer wall.

[0006] The front and rear sides of the top of the ladle cylinder are both provided with pouring gates, the left and right sides of the top of the ladle cylinder are both fixedly installed with positioning plates, and the top of the positioning plates is provided with a through hole.

[0007] An end cover is movably mounted on the top of the ladle cylinder, a heater is fixedly mounted on the middle portion of the top of the end cover, and a plurality of molybdenum alloy electric heating tubes are fixedly mounted on the bottom of the heater.

[0008] L-frames are fixedly installed on both sides of the top of the end cover, a vertical rod is fixedly installed on the bottom of the L-frame, and a limit plate is fixedly installed on the bottom of the vertical rod.

[0009] A cylinder cover is fixedly installed on the middle part of the outer wall of the ladle cylinder, and support rods are fixedly installed on the left and right sides of the cylinder cover.

[0010] A fixing plate is fixedly mounted on one end of the support rod, and positioning holes are provided on both sides of the front side of the fixing plate.

[0011] A sealing plug is fixedly installed on the bottom of the end cover.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model realizes the function of improving the thermal insulation performance of the ladle through the mutual cooperation between the overall structures. Therefore, the double insulation layer and the air insulation layer can be used to isolate and reflect the heat of the casting liquid layer by layer, thereby increasing the durability of the casting ladle and reducing the heat loss of the casting liquid to the outside. At the same time, it can also avoid the cooling effect of the external environment on the casting ladle, thereby ensuring the temperature stability of the casting liquid during transportation and waiting. At the same time, it also reduces the frequency of reheating of the casting liquid, reduces heating energy consumption, and solves the problem of poor thermal insulation effect of the single insulation layer of the traditional casting ladle.

[0014] 2. The utility model facilitates the cooperation with the vertical rod to ensure the verticality of the end cover and the ladle cylinder through the arrangement of the positioning plate and the through hole, thereby ensuring that when the end cover closes the top opening of the ladle cylinder, the end cover can close the gate, thereby achieving the purpose of reducing the heat dissipation of the pouring liquid. Through the structural design of the heater and the molybdenum alloy electric heating tube, and through the mutual cooperation between the structures, the function of heating the pouring liquid is realized, thereby heating the pouring liquid to be poured, thereby achieving the purpose of compensating for the temperature loss of the pouring liquid during transportation and waiting.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 4 As shown, the utility model provides an insulation ladle structure for cast iron parts, including a ladle cylinder 1, the inner wall of the ladle cylinder 1 is provided with a high temperature resistant inner lining layer 2, the outer wall of the high temperature resistant inner lining layer 2 is fixedly installed with a first insulation layer 3, the outer wall of the first insulation layer 3 is fixedly installed with a plurality of fan-shaped vertical cylinders 4, the outer wall of the fan-shaped vertical cylinders 4 is fixedly installed with a second insulation layer 5, and the outer wall of the second insulation layer 5 is fixedly installed with an outer wall 6

[0024] Among them, through the structural design of the first insulation layer 3, the fan-shaped vertical tube 4, and the second insulation layer 5, and through the mutual cooperation between the structures, the function of multi-layer insulation is realized, which can effectively reduce the heat transfer from the inside of the ladle to the outside, thereby ensuring the stability of the pouring liquid temperature.

[0025] A pouring port 7 is provided on both the front and rear sides of the top of the ladle cylinder 1 , and a positioning plate 8 is fixedly installed on both the left and right sides of the top of the ladle cylinder 1 , and a through hole 9 is opened on the top of the positioning plate 8 .

[0026] Among them, the positioning plate 8 and the through hole 9 are conveniently matched with the vertical rod 14 to ensure the verticality of the end cover 10 and the ladle barrel 1, thereby ensuring that when the end cover 10 closes the top opening of the ladle barrel 1, the end cover 10 can close the gate 7, thereby achieving the purpose of reducing the heat dissipation of the pouring liquid.

[0027] An end cover 10 is movably mounted on the top of the ladle cylinder 1 , a heater 11 is fixedly mounted on the middle portion of the top of the end cover 10 , and a plurality of molybdenum alloy electric heating tubes 12 are fixedly mounted on the bottom of the heater 11 .

[0028] Among them, the end cover 10 is used to facilitate closing the top opening of the ladle cylinder 1, thereby limiting the casting liquid and preventing the casting liquid from splashing out of the ladle cylinder 1 during transportation, thereby increasing the safety of the ladle. Through the structural design of the heater 11 and the molybdenum alloy electric heating tube 12, and through the mutual cooperation between the structures, the function of heating the casting liquid is realized, thereby heating the casting liquid to be poured, thereby achieving the purpose of compensating for the temperature loss of the casting liquid during transportation and waiting.

[0029] An L-frame 13 is fixedly mounted on both sides of the top of the end cover 10 , a vertical rod 14 is fixedly mounted on the bottom of the L-frame 13 , and a limit plate 15 is fixedly mounted on the bottom of the vertical rod 14 .

[0030] Among them, the L-frame 13 is used to provide additional space for the end cover 10 to descend, thereby ensuring that the end cover 10 completely closes the gate 7 when in use. The vertical rod 14 is used to limit the end cover 10, further ensuring the sealing of the ladle when in use. The limiting plate 15 is used to limit the stroke of the end cover 10, avoiding excessive movement of the end cover 10 from the ladle barrel 1, causing the molybdenum alloy electric heating tube 12 to collide with buildings or machinery in the external environment, further improving the safety of the ladle when in use.

[0031] A cylinder cover 16 is fixedly mounted through the middle portion of the outer wall of the ladle cylinder 1 , and support rods 17 are fixedly mounted on both the left and right sides of the cylinder cover 16 .

[0032] The ladle body 1 is fixed and protected by the barrel cover 16 to avoid damage to the ladle body 1 caused by external environmental interference during transportation.

[0033] A fixing plate 18 is fixedly mounted on one end of the support rod 17 , and positioning holes 19 are formed on both sides of the front surface of the fixing plate 18 .

[0035] A sealing plug 20 is fixedly mounted through the bottom of the end cover 10 .

[0036] The sealing plug 20 facilitates closing the waist opening of the ladle cylinder 1, and the multi-stage insulation layer is used to improve the performance of preventing the heat loss of the pouring liquid.

[0037] The working principle and usage process of the utility model: When using this device, pour the casting liquid through the top opening of the ladle cylinder 1, and close the top opening of the ladle cylinder 1 through the end cover 10. During this period, the vertical rod 14 cooperates with the through hole 9 to ensure that the end cover 10 rises and falls vertically, and the end cover 10 is limited by the top opening of the ladle cylinder 1. As the end cover 10 descends, the waist opening of the ladle cylinder 1 is closed by the sealing plug 20, and the connection between the ladle cylinder 1 and the gate 7 is closed by the end cover 10. The internal heat is blocked by the first insulation layer 3, and the first insulation layer 3 and the second insulation layer 5 are separated and supported by the fan-shaped vertical cylinder 4. At the same time, it provides additional space to form an air barrier to reduce heat transfer, and isolates the gas in the external environment through the second insulation layer 5, and at the same time blocks the heat of the air barrier. During the transportation of the ladle, the heater 11 heats the casting liquid through the molybdenum alloy electric heating tube 12.

[0038] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention.
