A new type of smoking cover for casting

Abstract

This utility model belongs to the field of casting technology, and specifically relates to a novel fume hood for casting, including a flue assembly. The end of the flue assembly is connected to a fume hood assembly, which includes fume hood bodies on both sides. The fume hood bodies on both sides are rotatably connected to the end of the flue assembly and are driven to rotate by a fume hood rotation drive, causing the fume hood bodies on both sides to rotate outwards and converge inwards. The fume hood bodies on both sides have corresponding notches for the passage of lifting equipment hooks. This utility model provides a novel fume hood for casting, where the fume hood bodies are rotatably connected. Without affecting normal lifting operations, the fume hood bodies are positioned at the top of the molten steel ladle, greatly improving the fume extraction effect. Furthermore, the rotating flue can also rotate, thus meeting the fume extraction needs of two casting stations.

Description

Technical Field

[0001] This utility model belongs to the field of casting technology, specifically relating to a novel fumigation hood for casting. Technical Background

[0002] During the steelmaking and casting process, a large amount of flue gas is generated. Since the molten steel ladle is not disconnected from the crane hook during the casting process, the dust collector flue in the current structure cannot be set at the top of the molten steel ladle (setting it at the top of the molten steel ladle would seriously affect the lifting and transportation of the crane hook). Therefore, the current structure generally adopts a side-suction dust collection structure, that is, the dust collection port is located on the side above the molten steel ladle. This method has a disadvantage: since the flue gas rises directly above the furnace opening, it is difficult for the side-suction type to suck up all the flue gas, and the smoke extraction effect is not ideal. Utility Model Content

[0003] This invention provides a novel fumigation hood for casting, which can solve the problems pointed out in the background art.

[0004] A novel fume hood for casting includes a flue assembly. The end of the flue assembly is connected to a fume hood assembly. The fume hood assembly includes fume hood bodies on both sides. The fume hood bodies on both sides are rotatably connected to the end of the flue assembly and are driven to rotate by the rotation of the fume hood, causing the fume hood bodies on both sides to rotate outwards and converge inwards. The fume hood bodies on both sides are provided with notches at corresponding positions for the passage of lifting hooks.

[0005] Preferably, the flue assembly includes a three-way flue at the end, through which the two ends of the three-way flue are rotatably connected to the smoke hoods on both sides.

[0006] Preferably, the two smoke hoods are symmetrically arranged and are rotatably connected to the three-way flue via a smoke hood pipe slewing support, and the smoke hood rotation drive is a geared motor.

[0007] Preferably, the flue assembly further includes a fixed flue and a rotary flue, wherein the rotary flue is rotatably connected to the end of the fixed flue and is driven to rotate by the rotation of the flue.

[0008] Preferably, the rotary flue is rotatably connected to the end of the fixed flue via a flue rotary support, and the flue rotation drive is a geared motor.

[0009] Beneficial effects: This utility model provides a novel fumigation hood for casting. The fumigation hood body is connected by a rotary mechanism. Without affecting normal hoisting, the fumigation hood body is placed at the top of the molten steel ladle, which can greatly improve the fumigation effect. In addition, the rotary flue can also rotate, thereby meeting the fumigation needs of two casting stations. Attached Figure Description

[0011] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0012] Example 1: As Figure 1-3 As shown in the figure, this utility model provides a novel fumigation hood for casting, including a flue assembly. The end of the flue assembly is connected to a fumigation hood assembly. The fumigation hood assembly includes two fumigation hood bodies 2 on both sides, which are horizontally arranged with the dust extraction port located at the bottom, corresponding to the upper opening of the ladle 5. The two fumigation hood bodies 2 on both sides are rotatably connected to the end of the flue assembly and are driven to rotate by a fumigation hood rotation drive 3, causing the two fumigation hood bodies 2 to rotate outwards and converge inwards. Rotating outwards means they are in an idle state, which does not affect the normal hoisting of the lifting equipment. Rotating inwards means they are in the fumigation working state, at which time they are located directly above the ladle 5 and can be used for fumigation operations. Since the ladle 5 is connected to the lifting equipment hook 6, the corresponding positions of the two fumigation hood bodies 2 are provided with notches 21. The notches 21 are used for the passage of the lifting equipment hook, i.e., avoiding the lifting equipment hook 6 and allowing it to pass through, so that the two do not interfere with each other.

[0013] Specifically, the flue assembly includes a three-way flue 11 at the end, through which the two ends of the three-way flue 11 are rotatably connected to the smoke hoods 2 on both sides. The two ends of the three-way flue 11 are located on the upper sides, and the smoke hoods 2 on both sides are symmetrically arranged. They are rotatably connected to the three-way flue 11 through smoke hood pipe rotatable supports 4. The smoke hood rotatable drive 3 is a geared motor.

[0014] Example 2: Combination Figure 1As shown, the flue assembly also includes a fixed flue 12 and a rotary flue 13. The rotary flue 13 is rotatably connected to the end of the fixed flue 12. The fixed flue 12 is vertically arranged, and the rotary flue 13 is rotatably connected to the top of the fixed flue 12 and is driven to rotate by the flue rotation drive 14. The end of the rotary flue 13 is connected to a three-way flue 11.

[0015] Specifically, the rotary flue 13 is rotatably connected to the end of the fixed flue 12 via the flue rotary support 15, and the flue rotary drive 14 is a geared motor.

[0016] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
