Abstract

The utility model discloses a float glass melting furnace. The float glass melting furnace comprises a feed port arranged on a melting furnace, small furnaces and exhausting devices arranged on the outer walls on the two sides of the melting furnace, and exhaust openings of the exhausting devices arranged between the feed port and the small furnaces and on the outer walls of the melting furnace. The exhausting device comprises a chimney and a chimney base for supporting the chimney, wherein a smoke flue communicated with the exhaust openings and the chimney is arranged inside the chimney base. The float glass melting furnace can utilize the suction force of the chimney to discharge part of dust from the chimney, so as to reduce the probability of dust falling into lattices to block the lattices, stabilize the melting quality and improve the production efficiency. The float glass melting furnace can reduce the temperature at the furnace crown and reduce the heat load of the furnace crown, so as to prolong the service life of the melting furnace. The float glass melting furnace is suitable for supporting when the float glass melting furnace uses solid fuel.

Description

Float glass smelting kiln

Technical field

The utility model relates to a kind of glass manufacturing apparatus, is a kind of float glass smelting kiln specifically.

Background technology

Float glass process results from late 1950s, advantages such as it obtains polishing and be shaped and gain the name because of glass metal swims in molten metal surface, and the glass surface that makes in this way is smooth, good product quality, output height, production cost are low, wide in variety; Float glass surface quality, physical strength and better heat stability have been widely used in fields such as automobile, steamer, aircraft at present.The glass furnace that is used for float forming technology is called float glass smelting kiln, float glass smelting kiln is compared with other sheet glass melting furnaces, there is not too big difference on the structure, belong to shallow pond transverse flame tank furnace, but on scale, float glass smelting kiln is much bigger, float glass smelting kiln day fusing amount can reach more than the 1000t in the world at present, but traditional float glass smelting kiln is at the kiln hood non air exit hole, when float glass smelting kiln uses solid fuel, cause the part dust in the melting furnaces proparea easily, proparea checker inner accumulated, this will make the temperature on arch top raise, thereby has increased the weight of the thermal load on arch top, the therefore work-ing life that can reduce melting furnaces, and the checker meeting of obstruction reduces refining quality, reduction productivity.

The utility model content

Goal of the invention: the purpose of this utility model be for solve the deficiencies in the prior art, provide a kind of can increase the service life, improve refining quality and improve to produce heroic lovers float glass smelting kiln.

Technical scheme: for addressing the above problem, a kind of float glass smelting kiln described in the utility model, comprise the dog-house that is located on the melting furnaces, be arranged in port and gas barrier on the exterior wall of melting furnaces both sides, having the venting hole that gas barrier is installed between described dog-house and the port and on the exterior wall at melting furnaces.Adopt this scheme, the part dust in the float glass smelting kiln can be discharged melting furnaces by venting hole and gas barrier.

Wherein, described port can have a plurality of, and described venting hole is at dog-house with between the port of close dog-house.

Described gas barrier comprises chimney and supports the chimney base of chimney that chimney base inside is provided with the flue that is communicated with described venting hole and chimney.

Beneficial effect: compared with prior art, the utility model has the advantages that the draft that utilizes chimney discharges the part dust from this chimney, enter checker, stop up the probability of checker, stablized refining quality, improved production efficiency thereby reduce dust; Can reduce the temperature on arch top, alleviate the thermal load on arch top, thereby can prolong the work-ing life of melting furnaces; Be applicable to carry out when float glass smelting kiln uses solid fuel supporting.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, the utility model float glass smelting kiln, comprise the dog-house 2 that is located on the float glass smelting kiln 1, be arranged in port 3 and gas barrier on the melting furnaces 1 both sides exterior wall, described port 3 can have a plurality of, between the port 3 of dog-house 2 and the most close dog-house 2 and on the exterior wall of melting furnaces 1, have the venting hole 4 that gas barrier is installed, gas barrier comprises chimney 6 and chimney base 5, chimney 6 and chimney base 5 vertical installations, one end of chimney base 5 is installed in the outside of venting hole 4, the other end is installed dust guard, is provided with the flue 7 that is communicated with venting hole 4 and chimney 6 in chimney base 5 inside.Part dust in the float glass smelting kiln is discharged melting furnaces through venting hole, flue and chimney successively.

The above only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
