Embodiment
As shown in Figure 1, the utility model is installed in the both sides outer wall of the big cover of molten tin bath B by at least 2 couples of gas barrier A, and every couple of gas barrier A installs in the two side external symmetry, mainly is distributed in the high-temperature zone in the molten tin bath groove, also can arrange at narrow section simultaneously.In time discharge in order to the dusty gas that space in the molten tin bath groove is contained highly volatiles such as SnO and SnS, avoid or reduce it, effectively reduced float glass surface imperfection odds at colder position condensation, gathering, the drippage in surface such as molten tin bath top cover; Gas barrier A one comprises that the gas exhaust duct of three ports and stationary installation assemble, wherein a port be arranged in this molten tin bath sidewall and with its groove in the space connect, two other port is fixedly installed in the outside of molten tin bath sidewall, and its port is separately installed with sealing cover or upper cover plate.
Below by two specific embodiments the utility model is described in further detail.
Embodiment 1:
As Fig. 2, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, gas barrier is provided with type pipe 1, a T type pipe 2 always; One port of straight type pipe 1 penetrates in the pilot hole of offering on the breastwork of molten tin bath sidewall 6 in advance 61, and the straight type pipe 1 that is inserted in the pilot hole 61 is communicated with space in the molten tin bath groove.The another port 11 of straight type pipe 1 is equipped with flange, and the contact surface welding of the big cover sidewall steel plate of this flange and molten tin bath outside surface is fixing.
T type pipe 2 is a Y-tube, and three ports respectively are furnished with flange, and the port that is positioned at horizontal transverse tube two ends is 21,22, the blind flange of the fixedly connected sealing usefulness of the flange of port 21; Be welded with the single head double-screw bolt in the through hole of port 22 flanges, fixedly connected with the flange of straight type pipe 1 port one 1 by the single head double-screw bolt; The vertical tube of vertical configuration is positioned at the middle part of this transverse tube, the port 23 of this vertical tube is a venting port, one rotation axis fixedly is housed on the ring flange of venting port, be installed with a upper cover plate 5 on the rotation axis, the size of upper cover plate 5, shape conform to venting port size, the shape of its port 23, and upper cover plate 5 turns opens or close;
When upper cover plate 5 rotarily opens, volatile dusty gas enters T type pipe 2 by straight type pipe 1 in the interior space of molten tin bath groove, and at this moment, port 21 places of T type pipe 2 are sealed by hard-wired blind flange, make its dusty gas enter vertical tube, discharge by the exhaust ports of port 23 again by transverse tube; When venting port was sealed in upper cover plate 5 rotations, gas barrier was in closing condition; When needing, the blind flange at port 21 places of T type pipe 2 can be opened, remove the impurity that stockpiles in the transverse tube, guarantee the unimpeded of its air-flow discharging; The big I manual regulation of the aperture of upper cover plate 5, with control free air delivery what.
Because gas is in the condition of high temperature in the molten tin bath groove, so straight type pipe 1 is all selected heat-resistant tube for use with T type pipe 2, its shape is the cylinder type hollow pipe, and the inside and outside diameter of pipe is identical, and port fixed flange model is also identical.
The vertical tube body top of T type pipe 2 is connected with the big cover sidewall 6 of molten tin bath by a stationary installation, and this stationary installation is made up of pipe clamp 3 and bearing 4, and bearing 4 is that a bucking ladder is planar, and the welding of the big cover sidewall steel plate of its bottom side and molten tin bath outside surface is fixing; Pipe clamp 3 is the steel pipe card, the head of steel pipe card is two curved splints that coincide with the tubular form of T type pipe 2 vertical tubes, its afterbody is two parallel block plates, offer screw in its end, fixedly connected with the top of bearing 4 by bolt, the head of steel pipe card is established the vertical tube of T type pipe 2 folder therebetween, thus with the vertical tube body of T type pipe 2 perpendicular to ground and be fixed on the big cover sidewall steel plate 6 of molten tin bath.
Embodiment 2:
As Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, the assembling of gas barrier and parts annexation are identical with embodiment 1, its difference is: the pilot hole 61 that present embodiment will be installed straight type pipe 1 is opened on the movable banding of being made up of metal shell 7, one port level of straight type pipe 1 penetrates in this pilot hole 61, the flange of the other end port one 1 is stuck in the outside surface of movable banding 7, and both contact position welding are fixing.Again the through hole on the flange of the flange of T type pipe 2 by its transverse tube port 22 and straight type pipe 1 port one 1 is aligned,, implement to be tightly connected by being welded on the single head double-screw bolt on port one 1 flange; The vertical tube body length of T type pipe is longer than the body length of embodiment 1; The stationary installation of fixedlying connected with it still is installed on the outside surface of the big cover sidewall steel plate 6 of molten tin bath of embodiment 1; Bearing 4 in this stationary installation is that a bucking ladder is planar, the big cover sidewall steel plate of its bottom side and molten tin bath outside surface riveted and fixed or be spirally connected fixing.
Principle of work of the present utility model is:
Upper cover plate 5 is controlled its aperture size by manual rotation, and when it was in opened condition, the dusty gas that groove contains highly volatiles such as SnO and SnS entered straight type pipe 1, through transverse tube, the vertical tube of T type pipe 2, is discharged into the atmosphere from port 23, at molten tin bath N
2+ H
2Under the well-off condition of mixed gas total amount, the dusty gas of discharging can account for 5～20% of the interior gas gross of molten tin bath groove, so both can guarantee the normal demand of the shielding gas amount in the groove, also can in time discharge the contaminated volatilization gas of molten tin bath outside the molten tin bath, suppress these volatilization gas effectively at colder position condensation, gathering, drippages in surface such as molten tin bath top covers, thereby reduced float glass surface imperfection odds; The quality and the output of float shaping have been improved.
