Description

Technical Field

[0001] The invention relates to the technical field of metal smelting, and more specifically to a simple gas cooling and protection device for metal smelting. Background Art

[0002] In the processing of aluminum alloy, smelting and casting are the first production process. In this production process, the staff should add alloy elements to the remelted aluminum ingots and electrolytic aluminum liquid to prepare them into alloys. Then, the alloy is loaded into the furnace, and fuel is added to heat the furnace to melt the aluminum ingot and aluminum liquid alloy. After the aluminum alloy is melted, a certain amount of residue will be produced. The staff needs to clean up the residue and then stir it. In this process, the staff also needs to test the molten aluminum liquid, adjust its chemical composition, dilute and supplement it, so that the ratio of aluminum and other alloy elements meets the standard. After that, the staff needs to remove the slag, guide the furnace and clean the furnace again to make the aluminum alloy purer. After the aluminum alloy is melted and cleaned, it will be subjected to chloride salt refining and argon rotary blowing refining process to improve the quality of the aluminum alloy liquid. The refined aluminum alloy liquid must also be tested and processed online, and then it can be formed into a billet, and then aluminum alloy products are produced after casting.

[0003] When melting and casting aluminum alloys, production personnel are required to be in close contact with high-temperature molten aluminum at all times. In addition, there is a risk of molten aluminum bubbling or splashing due to operational negligence and equipment failure during the production process, which seriously threatens the safety of workers and equipment. Currently, most protective devices are cooling protection through gas spraying. Although it can slow down the bubbling of molten aluminum, it cannot prevent the bubbling of molten aluminum due to insufficient contact between the cooling gas and the molten aluminum, which can still threaten the safety of workers and equipment.

[0030] See also Figure 4A protective shell 410 is fixedly connected to the outside of the drying box 8, a gear ring 2 411 is fixedly connected to the outside of the protective shell 410, the gear ring 2 411 is meshed with the gear 408, the protective shell 410 is fixedly connected to the connecting ring 403, and a plurality of openings are provided at one end of the protective shell 410 close to the cooling box 405.

[0031] Specifically, the motor can control the rotation of the rotating shaft 406, and the rotation of the rotating shaft 406 drives the gear 408 to rotate. Since the gear 408 is meshed with the gear ring 2 411 and the gear ring 402, and the gear ring 2 411 and the gear ring 402 are fixed in position, the rotation of the gear 408 will drive the motor to rotate around the drying box 8, and then drive the cooling box 405 to rotate around the drying box 8. The rotation of the cooling box 405 around the drying box 8 will synchronously drive the rotating ring 404 to rotate, so that the motor can simultaneously rotate the cooling box 405 around the drying box 8, and perform gas jet cooling on the drying box 8, so that the cooling box 405 can be more evenly gas-jet cooled, thereby reducing the bubbling of the liquid in the drying box.

[0032] See also Figure 3 and Figure 4 The cooling box 405 is fixedly connected to one end of the connecting ring 403 near the connecting ring 403 with a connecting pipe 409, and the connecting pipe 409 penetrates the rotating ring 404. A groove is provided on the protective shell 410, and a rotating ring 2 412 is slidably connected to the groove. The rotating ring 2 412 is provided with an opening 1, and the opening 1 is fixedly connected to the connecting pipe 409.

[0033] The gear 408 is slidably connected to the connecting ring 403 , the gear 408 is rotatably connected to the rotating ring 404 , and one end of the gear 408 away from the connecting ring 403 is fixedly connected to the rotating shaft 406 .

[0034] Specifically, when the cooling box 405 rotates around the drying box 8, it will drive the connecting pipe 409 to rotate synchronously, and the connecting pipe 409 is fixedly connected to the rotating ring 2 412, so that the rotation of the connecting pipe 409 will drive the rotating ring 2 412 to rotate, and then drive the connecting pipe 2 413 and the rotating ring 3 414 to rotate synchronously. During the rotation of the rotating ring 2 412 and the rotating ring 3 414, a gap will be generated between the protective shell 410, and part of the cooling gas discharged from 10 can enter the cavity between the rotating ring 2 412 and the rotating ring 3 414 through the gas, and cool the drying box 8 through heat exchange in the cavity. At the same time, the synchronous rotation of the rotating ring 2 412 and the connecting pipe 409 will not affect the cooling gas from entering the cooling box 405 through the rotating ring 3 414.

[0035] See also Figure 6 The secondary protection component 6 includes a second shell 601 fixedly connected to the processing box 9, an end of the second shell 601 close to the drying box 8 is fixedly connected to an electric telescopic rod 602, and an end of the electric telescopic rod 602 away from the second shell 601 is fixedly connected to a pressing plate 603. An opening 2 is provided on one side of the second shell 601, and the opening 2 is fixedly connected to the feed port 7.

[0036] Specifically, when the sensor at the dry box 8 senses that the liquid in the dry box 8 is about to overflow, the electric telescopic rod 602 will be controlled to drive the pressing plate 603 to move downward to cover the dry box 8. When the sensor in the dry box 8 senses that the temperature of the liquid in the dry box 8 drops to the required level, the electric telescopic rod 602 will be controlled to drive the pressing plate 603 to move upward, so that the pressing plate 603 no longer covers the dry box 8, and the cooling box 405 will be controlled to stop spraying cooling gas synchronously.

[0037] See also Figure 7 The processing box 9 includes a top cover 901 fixedly connected to the protection box 4, an air suction box 902 is fixedly connected to the inner side of the top cover 901, the air suction box 902 is fixedly connected to the protection box 4, a filter is arranged inside the air suction box 902, and a connecting plate 903 is fixedly connected to one end of the air suction box 902 close to the drying box 8, and a plurality of openings are arranged on the connecting plate 903.

[0038] Specifically, the waste generated after cooling will flow between the connecting plate 903 and the top cover 901 through the opening three on the connecting plate 903, and the air suction box 902 in the top cover 901 can absorb the waste gas between the top cover 901 and the connecting plate 903 and discharge it after filtering, thereby reducing the pollution of the waste gas to the environment.

[0039] See also Figure 5 A plurality of jet pipes 415 are fixedly connected to one end of the cooling box 405 close to the drying box 8. The jet pipes 415 are arranged in a stepped manner and inclined upward. An infrared emitter 416 is provided at one end of each jet pipe 415 away from the connecting pipe 409. The infrared emitter 416 is fixedly connected to the cooling box 405 and is located directly above the jet pipe 415.

[0040] Specifically, the infrared transmitter 416 can emit infrared rays, which are reflected by the infrared reflection ring on the housing 401, so that the jet tube 415 can remain in place without retracting or extending. When the infrared rays emitted by the infrared transmitter 416 cannot receive the reflected signal due to being blocked by an object, the infrared transmitter 416 will control the jet tube 415 below to retract. When the infrared transmitter 416 receives the reflected signal, the infrared transmitter 416 will control the jet tube 415 to extend until the jet tube 415 extends to the end.

[0041] Working principle of the present invention: the motor can control the rotation of the rotating shaft 406, and the rotation of the rotating shaft 406 drives the gear 408 to rotate. Since the gear 408 is meshed with the gear ring 2 411 and the gear ring 402, and the positions of the gear ring 2 411 and the gear ring 402 are fixed, the rotation of the gear 408 will drive the motor to rotate around the drying box 8, and then drive the cooling box 405 to rotate around the drying box 8. The rotation of the cooling box 405 around the drying box 8 will synchronously drive the rotating ring 404 to rotate, so that the motor can simultaneously rotate the cooling box 405 around the drying box 8, and perform gas jet cooling on the drying box 8, so that the cooling box 405 can perform gas jet cooling more evenly, thereby reducing the liquid in the drying box. Bubbling occurs in the body, and the cooling box 405 rotates around the drying box 8, which will drive the connecting pipe 409 to rotate synchronously, and the connecting pipe 409 is fixedly connected to the rotating ring 2 412, so that the rotation of the connecting pipe 409 will drive the rotating ring 2 412 to rotate, and then drive the connecting pipe 2 413 and the rotating ring 3 414 to rotate synchronously, and in the process of the rotation of the rotating ring 2 412 and the rotating ring 3 414, a gap will be generated between the protective shell 410, and part of the cooling gas discharged from 10 can enter into the cavity between the rotating ring 2 412 and the rotating ring 3 414 through the gap, and cool the drying box 8 through heat exchange in the cavity, and the exhaust gas after heat exchange will pass through the protective shell 410 The opening at the upper end flows to the processing box 9, and the synchronous rotation of the rotating ring 2 412 and the connecting pipe 409 will not affect the cooling gas entering the cooling box 405 through the rotating ring 3 414. When the sensor at the drying box 8 senses that the liquid in the drying box 8 is about to overflow, the electric telescopic rod 602 will be controlled to drive the pressing plate 603 to move downward to cover the drying box 8. When the pressing plate 603 descends to the infrared transmitter 416, the infrared rays emitted by the infrared transmitter 416 will be blocked. At this time, the infrared transmitter 416 will control the jet pipe 415 below to retract, so that the pressing plate 603 will not be blocked by the jet pipe 415 when it descends. At the same time, when the pressing plate 603 When it descends to the point where it no longer blocks the infrared rays at the infrared emitter 416, the jet pipe 415 will extend again to continue to perform gas cooling on the drying box 8. At this time, the jet pipe 415 will spray cooling gas on the upper surface of the pressing plate 603, so that the cooling gas can cool the pressing plate 603 through heat exchange, and then cool the liquid in the drying box 8. When the sensor in the drying box 8 senses that the temperature of the liquid in the drying box 8 has dropped to the required level, the cooling box 405 will be controlled to synchronously stop spraying cooling gas and retract into the interior of the cooling box 405. At the same time, the suction box 902 will be controlled to drive the connecting plate 903 to move upward, so that the connecting plate 903 no longer covers the drying box 8 tightly.
