Description
Technical field
The utility model relates to sheet glass production field, particularly relates to a kind of molten tin bath sheet glass and pollutes slowing device.
Background technology
In sheet glass floating process, molten tin bath is the former of splendid attire tin liquor.After the glass metal of melting enters molten tin bath, can floating in tin liquor, shakeout and be shaped.Because tin liquor is oxidizable, therefore the shielding gas mixed with nitrogen by hydrogen must be injected in molten tin bath when producing, in order to consume and starvation.And in actual use; always having a small amount of oxygen infiltrates in molten tin bath; make a small amount of tin liquor oxidized, and produce tin protoxide (SnO) gas, when the shielding gas temperature being mixed with tin protoxide gaseous constituent is down to after below 870 DEG C; tin protoxide gas can be condensed into the solid powdery of tin compound; be called tin ash, tin ash, once tin ash is shed on glass ribbon, will produce light distortion point; form points of contamination, affect the quality of product.So the normal mode adopting alternately pressurization decompression, carries out timing cleaning to molten tin bath at present, makes tin ash concentrate and comes off, cause the concentrated contaminated water of sheet glass.
Summary of the invention
The purpose of this utility model is to solve tin ash under prior art and easily drops on glass ribbon, needs the technical problem of carrying out continually cleaning, and provides a kind of molten tin bath sheet glass to pollute slowing device.
The purpose of this utility model is achieved by the following technical programs:
A kind of molten tin bath sheet glass pollutes slowing device, comprise sidewall, top cover and shell, wherein sidewall and top cover, inlet chamber is provided with between shell, inlet chamber is communicated with protection source of the gas by pipeline, described top cover is combined by one group of top cover brick and forms, each top cover brick is all connected with shell by suspension connecting piece, gap is left between top cover brick, inject for shielding gas, it is characterized in that between adjacent top cover block, being provided with main control of dust block, main control of dust block upper end is provided with the first open slot, align mutually in gap between first open slot and described adjacent top cover block, be communicated with, uniform one through hole is ranked first along its length bottom the first open slot, first through hole level runs through the first open slot, the first extension boss is respectively equipped with in its both sides, lower end along main control of dust block length direction.
Secondary control of dust block is provided with between described top cover brick and sidewall, secondary control of dust block side is provided with the second open slot, second open slot and the gap between described top cover brick and sidewall mutually concordant, be communicated with, uniform one through hole is ranked second along its length bottom second open slot, second through hole level runs through the second open slot, is provided with the second extension boss along secondary control of dust block length direction in its opposite side lower end.
Described main control of dust block is consistent with the material of top cover brick with the material of secondary control of dust block, is all that fire proof material brick is made, and wherein main control of dust block is I shape, secondary control of dust block is concave character type.
The beneficial effects of the utility model are that structure is simple, cheap for manufacturing cost, by accepting tin ash in molten tin bath, extending the cleaning period of molten tin bath, slow down the pollution that tin ash causes product.
Below just accompanying drawings and embodiment the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is that the utility model master cuts open structural representation;
Fig. 2 is the perspective view of main control of dust block;
Fig. 3 is the perspective view of secondary control of dust block.
Embodiment
As shown in Figure 1, a kind of molten tin bath sheet glass provided for the utility model pollutes slowing device, comprise sidewall 2, top cover 3 and shell 1, wherein sidewall 2 and top cover 3, inlet chamber 1a is provided with between shell 1, inlet chamber is communicated with protection source of the gas by pipeline 5, described top cover 3 is combined by one group of top cover brick 3a and forms, each top cover brick 3a is all connected with shell 1 by suspension connecting piece 4, gap is left between top cover brick 3, inject for shielding gas, the main control of dust block 6 of I shape is provided with between described adjacent top cover block 4, main control of dust block upper end is provided with the first open slot 6a, align mutually in gap between first open slot 6a and described adjacent top cover block 3a, be communicated with, uniform one through hole 6b is ranked first along its length bottom the first open slot 6a, first through hole 6b level runs through the first open slot 6a, the first extension boss 6c is respectively equipped with at its lower end both wings along main control of dust block 6 length direction, the secondary control of dust block 7 of concave character type is provided with between described top cover brick 3a and sidewall 2, secondary control of dust block 7 side is provided with the second open slot 7a, second open slot 7a and the gap between described top cover brick 3a and sidewall 2 mutually concordant, be communicated with, uniform one through hole 7b is ranked second along its length bottom second open slot 7a, second through hole 7b level runs through the second open slot 7a, is provided with the second extension boss 7c along secondary control of dust block length direction in its opposite side lower end.
When producing, shielding gas injects inlet chamber 1a through pipeline 5, shielding gas in inlet chamber can from the gap between top cover brick 3a, gap between top cover brick 3a and sidewall 2 enters the first open slot 6a of main control of dust block 6, in second open slot 7a of secondary control of dust block 7, inject in molten tin bath space from the first open slot 6a through the first through hole 6b again, inject in molten tin bath space from the second open slot 7a through the second through hole 7b, when shielding gas is from the first through hole 6b, when second through hole 7b injects molten tin bath, the shielding gas of low temperature can make the tin protoxide gas of high temperature condense into pressed powder at inlet place, when pressed powder comes off, by the first extension boss 6c, the stop of the second extension boss 7c, pressed powder would not be shed on sheet glass, thus greatly can extend the cycle that molten tin bath carries out timing cleaning.
