Embodiment Construction
[0014] The present invention will be described in further detail below by means of specific embodiments:
[0015] The reference signs in the drawings of the specification include: tin bath body 1, outlet bottom brick 2, tin liquid 3, gap 3a, gap 3b, linear motor 4, cavity 41, heat insulation layer 5, air injection hole 51, cooling pipe 6 , plate glass 7, intake pipe 8, leading screw 9.
[0016] Such as figure 1 The shown tin bath for producing glass includes a tin bath body 1 filled with tin liquid 3, and the right end of the tin bath body 1 is provided with a glass outlet. At the bottom of the tin bath body 1, a set of bottom bricks matched with each other is arranged, and an outlet bottom brick 2 is arranged on the lower side of the glass outlet. The tin blocking device is provided on the outlet bottom brick 2, and the tin blocking device includes a linear motor 4. The right side of the linear motor 4 is provided with a vertical lead screw 9, and the lead screw 9 is fixedl...

The invention discloses a tin bath for producing glass. The tin bath comprises a tin bath body, wherein the tin bath body is filled with tin liquor; one end of the tin bath is provided with a glass outlet opening; the bottom of the tin bath body is provided with one group of bottom bricks cooperating with one another; a tin baffling device is arranged at the glass outlet opening; the tin baffling device comprises a linear motor; a heat insulating layer enwraps the linear motor; the heat insulating layer is fixedly connected with the bottom bricks; the upper surface of the heat insulating layer at the top of the linear motor is lower than the liquid-level height of the tin liquor; the upper part of the linear motor is provided with a cavity; the top of the linear motor is provided with a plurality of gas jetting holes communicated with the cavity; the gas jetting holes upwards extend and run through the heat insulating layer; the linear motor is provided with a gas inlet pipe communicated with the cavity; the gas inlet pipe is communicated with a nitrogen compressor. The problem that air enters the tin bath through a gap between the heat insulating layer and sheet glass to result in oxidation caused to the tin liquor is solved.
Description
technical field [0001] The invention relates to the field of forming float glass. Background technique [0002] In the flat glass float process, the tin bath is a forming device used to contain molten tin liquid. The molten glass flows into the tin bath from the inlet end, floats on the tin liquid and spreads flat to form flat glass, and solidifies the formed flat glass. The glass ribbon leaves the tin bath from the exit end, and at the exit of the tin bath, in order to prevent the tin liquid from overflowing, the horizontal height of the upper plane of the bottom brick at the outlet must be higher than the tin liquid level, so the flat glass ribbon must first pass through the climbing section before it can move horizontally At this time, the flat glass ribbon has been hardened and formed, and climbing up will reduce the yield of flat glass. In the publication number CN104310760, the patent name is a tin blocking device for a flat glass horizontal outlet tin tank, which inc...
