Description
Technical Field
[0001] The utility model belongs to the technical field of float glass production, and particularly relates to a fixing structure of a tin bath retaining wall. Background Art
[0002] The production process of float glass generally includes raw material crushing, weighing, mixing, melting, forming and annealing. The forming process of float glass is completed in a tin bath, which contains high-temperature tin liquid. The molten glass flows into the tin bath continuously from the inlet end and floats on the surface of the tin liquid with a larger specific gravity. After flattening, polishing, forming, cooling and other processes, it gradually cools and hardens along the length of the tin bath. Finally, it is lifted to the transition roller table at the outlet end of the tin bath, enters the annealing kiln through the transition roller table, and then completes the subsequent process. The forming principle of float glass is that the molten glass liquid produces flat glass of the required thickness and width under the combined action of its own gravity, surface tension, annealing roller traction and edge drawing machine pulling force.
[0003] As the glass moves backward in the tin bath, its temperature gradually decreases, causing the temperature of the tin liquid in contact with it to gradually decrease. The tin liquid with a temperature difference is easy to flow, causing a slight fluctuation in the liquid surface of the tin liquid, which in turn affects the flatness of the glass product. In the prior art, baffles can be set on both sides of the tin bath to reduce the backflow of the tin liquid.
[0004] Common retaining edges include a fixing rod and a graphite plate at the lower side of the inner end of the fixing rod, etc. The fixing rod passes out of the tin bath and is fixed to the outer wall of the tin bath through a fixing structure. The fixing structure is an adjustable structure to adjust the position of the retaining edge.
[0005] For example, the patent with application number CN202021438464.8 discloses a float glass tin bath, comprising a tin bath arranged in the front-to-back direction and a plurality of retaining ridges on the left and right side walls of the tin bath, the tin bath being divided into a wide section, a contraction section and a narrow section from front to back, and a plurality of retaining ridges on the same side being arranged at intervals front to back, the retaining ridges comprising a fixing rod arranged in the left-to-right direction and a graphite plate on the lower side of the inner end of the fixing rod and arranged in the left-to-right direction, the graphite plate being arranged vertically and located at the bottom of the tin bath, the fixing rod being fixed on the side wall of the tin bath; the retaining ridges being arranged on the wide section, and the graphite plates being divided into a contraction section and a narrow section from inside to outside; It is a narrow plate section, an inclined plate section and a wide plate section, the lower sides of the narrow plate section, the inclined plate section and the wide plate section are flush, the width of the narrow plate section is smaller than the width of the wide plate section; the narrow plate section is located below the glass and the distance between the narrow plate section and the glass is 15-25mm, and the length is 400-600mm; the width of the inclined plate section gradually increases from the narrow plate section to the wide plate section and it is located directly below the corresponding side of the glass; the wide plate section is located outside the corresponding side of the glass, its upper side is located above the tin liquid, and its outer end is against the inner wall of the corresponding side of the tin bath; the inner end of the fixing rod is fixedly connected to the upper side of the wide plate section. The fixing rod passes out of the side wall of the tin bath, and a fixing structure is provided on the outer wall of the tin bath, and the fixing structure is fixedly connected to the fixing rod, and a supporting structure for supporting the fixing rod is provided outside the tin bath. The fixing structure comprises a bracket, a ring sleeve arranged on the bracket along the left-right direction and a locking bolt on the ring sleeve, the bracket is fixedly connected to the outer wall of the tin bath, the ring sleeve is arranged on the fixing rod and is composed of two semicircular semi-cylinders; one end of the two semi-cylinders is hinged, and the other ends are respectively provided with sockets; the sockets are arranged along the left-right direction and a pin is inserted therein to fix the two semi-cylinders together; the locking bolt is threadedly connected to the ring sleeve and its inner end rests on the fixing rod; the supporting structure comprises a base, a supporting rod arranged on the base along the vertical direction and a supporting plate at the upper end of the supporting rod and arranged along the left-right direction, the supporting plate is a V-shaped plate or an arc plate that cooperates with the fixing rod and is open upward, and the outer end of the fixing rod is placed on the supporting plate.
[0006] When the applicant used the above-mentioned fixing structure to fix the tin bath retaining edge, the following problems were found:
