[0003] Currently, when zinc furnaces are in use, a lot of zinc vapor condensation residue tends to accumulate on the furnace cover, which is not only difficult to clean, but also prone to corrosion of the furnace cover over time. Utility Model Content

[0004] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a zinc furnace cover that solves the problem that the zinc furnace cover in the existing technology is prone to the accumulation of a lot of zinc vapor condensation residue, which is not only troublesome to clean, but also easy to cause corrosion of the furnace cover over time.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a zinc furnace cover, installed on the upper end of the zinc furnace body, including a cover body, the upper end of the cover body is an upwardly convex arc shape, the lower end of the cover body is provided with a cover post that can be inserted into the inner cylinder of the zinc furnace, the outer side of the cover post is provided with a first sealing ring that can be tightly fitted with the inner cylinder of the zinc furnace, the outer side of the upper end of the first sealing ring is provided with a second sealing ring that can be pressed against the upper end of the inner cylinder of the zinc furnace, the bottom end of the cover post is a cone shape with the tip pointing downwards, and the surface of the bottom end of the cover post is coated with XG-T-2 type coating or boron nitride coating.

[0006] As a further improvement of this utility model, the bottom end of the cap post is provided with a shallow groove in the shape of a cross.

[0007] As a further improvement of this utility model, both the first sealing ring and the second sealing ring are made of graphite.

[0008] As a further improvement of this utility model, a support plate with an upward angle is provided on one side of the cover, and a support rod is fixedly connected to the upper part of the middle of the cover. The support rod is fixedly connected to the support plate. A hydraulic push rod is fixed on one side of the upper end of the zinc furnace body. A motor that can drive the support plate to rotate is connected to the upper end of the hydraulic push rod, and the upper end of the output shaft of the motor is fixedly connected to the support plate.

[0010] As a further improvement of this utility model, the cover body and the cover post are integrally manufactured.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. By installing a cover post at the lower end of the furnace cover, and a first sealing ring that can fit tightly against the inner cylinder of the zinc furnace on the outer side of the cover post, and a second sealing ring that can press against the upper end of the inner cylinder of the zinc furnace on the outer side of the upper end of the first sealing ring, the sealing effect of the furnace cover is improved, reducing the penetration of zinc vapor in the gaps of the furnace cover and reducing the condensation and deposition of zinc vapor. The second sealing ring can press against the furnace body of the zinc furnace, so that the furnace cover and the furnace body of the zinc furnace are tightly sealed in the vertical pressing direction, further reducing the penetration and leakage of zinc vapor.

[0013] The bottom surface of the cap column is coated with XG-T-2 type paint or boron nitride paint, which is non-wetting to molten zinc liquid, preventing zinc vapor from condensing and adhering, and is especially suitable for high-temperature zinc liquid (such as 435-465℃) environments, thus extending the service life of the equipment.

[0014] By designing the bottom of the cap column as a cone with the tip pointing downwards, it facilitates the flow of zinc vapor condensate, reduces zinc condensation and deposition on the cap column, and reduces corrosion and cleaning difficulty.

[0015] 2. By setting shallow grooves at the bottom of the cap column, the condensate of zinc vapor can flow downwards, reducing the condensation and deposition of zinc on the cap column, thus reducing corrosion and cleaning difficulty.

[0016] 3. By using graphite sealing rings for both the first and second sealing rings, graphite can withstand high-temperature environments above 500℃, does not react with zinc liquid or vapor, and has no wetting effect on zinc vapor, effectively reducing zinc dross adhesion.

[0017] 4. By gradually tilting the support rod downwards, a downward force is applied to the cover, making the cover fit more tightly and firmly onto the zinc furnace body.

[0018] 5. By making the cover and the cap column as one piece, the connection is smoother and easier to clean later. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0026] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0027] This utility model discloses a zinc furnace cover. (Refer to...) Figure 1 , Figure 2 and Figure 3 A zinc furnace cover is installed on the upper part of the zinc furnace body 10, which can be raised, lowered and rotated. It includes a cover body 1, the upper end of the cover body 1 is an upwardly convex arc shape, and the lower end of the cover body 1 is provided with a cover post 2 that can be inserted into the inner cylinder of the zinc furnace. The cover body 1 and the cover post 2 are made in one piece, and the connection is smoother, which facilitates later cleaning.

[0028] A first sealing ring 3 is attached to the outer side of the cover column 2 to fit tightly against the inner cylinder of the zinc furnace. A second sealing ring 4 is attached to the outer side of the upper end of the first sealing ring 3 to press against the upper end of the inner cylinder of the zinc furnace. Both the first sealing ring 3 and the second sealing ring 4 are made of graphite. By using graphite for both the first sealing ring 3 and the second sealing ring 4, graphite can withstand high-temperature environments above 500℃, does not react with zinc liquid or vapor, and has no wetting effect on zinc vapor, effectively reducing zinc dross adhesion.

[0029] like Figure 2 and Figure 4 As shown, the bottom of the cover column 2 is a cone shape with the tip pointing downwards, which facilitates the flow of zinc vapor condensate, reduces zinc condensation and deposition on the cover column 2, and reduces corrosion and cleaning difficulty. In addition, the bottom of the cover column 2 has shallow, cross-shaped grooves 5, which further facilitate the flow of zinc vapor condensate, reducing zinc condensation and deposition on the cover column 2, and reducing corrosion and cleaning difficulty. Furthermore, the bottom surface of the cover column 2 is coated with XG-T-2 type paint or boron nitride paint, which is non-wetting to molten zinc, preventing zinc vapor condensation and adhesion, making it particularly suitable for high-temperature zinc liquid environments and extending equipment lifespan.

[0030] like Figure 1As shown, one side of the cover 1 is fixedly connected to an upwardly inclined support plate 6. A support rod 7 is fixedly connected to the upper middle part of the cover 1, and the support rod 7 is fixedly connected to the support plate 6. A hydraulic push rod 8 is fixed to one side of the upper end of the zinc furnace body 10. The upper end of the hydraulic push rod 8 is connected to a motor 9 that can drive the support plate 6 to rotate. The upper end of the output shaft of the motor 9 is fixedly connected to the support plate 6. The support rod 7 is gradually inclined downward from the side away from the center of the cover 1 to the side closer to the center of the cover 1. This provides a downward force to the cover 1, making the cover 1 more tightly and firmly cover the zinc furnace body 10.

[0031] This invention improves the sealing effect of the furnace cover by setting a cover post 2 at the lower end of the furnace cover, and attaching a first sealing ring 3 to the outside of the cover post 2 so as to fit tightly with the inner cylinder of the zinc furnace. A second sealing ring 4 is attached to the outer side of the upper end of the first sealing ring 3 so as to press against the upper end of the inner cylinder of the zinc furnace. This reduces the penetration of zinc vapor in the gaps of the furnace cover and reduces the condensation and deposition of zinc vapor. The second sealing ring 4 can press against the furnace body 10 of the zinc furnace, so that the furnace cover and the furnace body are tightly pressed and sealed in the vertical pressing direction, further reducing the penetration and leakage of zinc vapor.
