Description

Furnace cover of zinc smelting furnace Technical Field The utility model belongs to the technical field of zinc melting furnaces, and particularly relates to a zinc melting furnace cover. Background The zinc melting furnace is mainly used for alloy preparation, surface pacing layer treatment, metal smelting and purification, and is mainly applied to the metallurgical and manufacturing industries. At present, when the zinc smelting furnace is used, more zinc steam is easy to precipitate on the furnace cover of the zinc smelting furnace, and precipitates left by condensation are easy to cause corrosion to the furnace cover due to accumulation of time. Disclosure of utility model In view of the defects and drawbacks existing in the prior art, the utility model aims to provide a zinc melting furnace cover, which solves the problems that more zinc vapor is easy to precipitate on the zinc melting furnace cover in the prior art, precipitates left by condensation are difficult to clean, and corrosion to the furnace cover is easy to cause due to accumulation of time. In order to solve the technical problems, the utility model adopts the following technical scheme that the furnace cover of the zinc melting furnace is arranged at the upper end of the furnace body of the zinc melting furnace and comprises a cover body, the upper end of the cover body is in an upward protruding arc shape, the lower end of the cover body is provided with a cover column which can be inserted into an inner cylinder of the zinc melting furnace, the outer side of the cover column is provided with a circle of first sealing ring which can be tightly attached to the inner cylinder of the zinc melting furnace, the outer side of the upper end of the first sealing ring is provided with a circle of second sealing ring which can be pressed on the upper end of the inner cylinder of the zinc melting furnace, the bottom end of the cover column is in a conical shape with a downward top, and the surface of the bottom end of the cover column is coated with XG-T-2 type paint or boron nitride paint. As a further improvement of the utility model, the bottom end of the cover column is provided with a rice-shaped shallow groove. As a further improvement of the utility model, the first sealing ring and the second sealing ring are both graphite sealing rings. As a further improvement of the utility model, one side of the cover body is provided with an obliquely upward supporting plate, the upper end of the middle part of the cover body is fixedly connected with a supporting rod, the supporting rod is fixedly connected with the supporting plate, one side of the upper end of the zinc smelting furnace body is fixedly provided with a hydraulic push rod, the upper end of the hydraulic push rod is connected with a motor capable of driving the supporting plate to rotate, and the upper end of an output shaft of the motor is fixedly connected with the supporting plate. As a further improvement of the present utility model, the support bar is gradually provided to be inclined downward from a side away from the center of the cover body to a side close to the center of the cover body.
