Abstract
The utility model discloses a throat for glass melting furnaces, which belongs to separating devices for glass metal. The utility model is mainly formed by that two side posts support a bridge cross beam. The footwall of the utility model is a step kiln weir, and a slope is arranged at the output of the utility model. The utility model can effectively prevent floating slag and sediments getting into a working tank, and the utility model has a good effect of clarifying and defoaming. The utility model has the advantages that the structure is simple, the cost of manufacturing is low, the service life is long, and the effect of separating the glass metal. The utility model can offer the glass metal with homogenisation, purity, and high quality for glass products.
Description
The utility model relates to a kind of cell furnace dog-hole, belongs to the glass metal separating device of cell furnace.
Cell furnace is the special-purpose Thermal Equipment that glass industry is produced, mainly bear founding of glass, the melting pool that the admixtion that exactly will be mix by material side drops into cell furnace forms glass metal through heat, flow into work pool after with glass metal clarification, homogenizing, deliver to feeding machine by the glass metal separating device, provide glass metal even, pure, transparent and that be suitable for being shaped for producing glasswork through the material road.According to " silicate industry thermal process and equipment " (China Construction Industry Press, in December, 1980 first version) record: dog-hole is common a kind of glass metal separating device, and it is mainly by placing two lateral columns and gap bridge crossbeam at the bottom of the melting pool to constitute.The cavity entrance shape of dog-hole is inclined to one side rectangular through holes, be communicated with melting pool and work pool, the scum silica frost that the gap bridge crossbeam of dog-hole can block glass metal surface in the melting pool enters work pool, but the impurity sediment in the glass metal easily enters work pool with glass metal by dog-hole, until feeding machine, like this, the glass metal that contains the impurity sediment will directly influence the quality product of glasswork; At present, the dog-hole width that is used for cell furnace is generally 300mm～500mm, the width of large tank furnace used dog-hole also only reaches 600mm, like this, place, flow liquid hole is the eck of a deflation, when glass metal when the melting pool of big section flows to dog-hole than light section, flow velocity increases, and has aggravated the erosion corrosion to dog-hole; Simultaneously, glass metal fails to be convened for lack of a quorum and rapid turbulent flow occurs, and this also is a reason that influences the glasswork quality.
The purpose of this utility model provides a kind of cell furnace dog-hole device, and it can separate the impurity sediment in the glass metal, can slow down the erosion corrosion of glass metal to dog-hole again, for feeding machine provides even, pure, clarifying high-quality glass metal.
The purpose of this utility model is achieved through the following technical solutions:
The cell furnace dog-hole, it mainly is made of gap bridge crossbeam of two lateral columns supports, and the dog-hole diapire is a stepped appearance weir.The cavity entrance shape of the dog-hole of Gou Chenging is one and is rectangular partially through hole like this, the melting pool and the work pool that are communicated with cell furnace, the gap bridge crossbeam can block the scum silica frost on the glass metal surface in the melting pool, the stepped appearance weir can stop the impurity sediment of glass metal, only allow the interior top-quality middle level of melting pool glass metal enter work pool, supply to produce used in glass products until feeding machine by dog-hole.Done a slope in the exit of dog-hole, made glass metal slowly rise to work pool along the slope, can further glass metal have been clarified homogenizing, discharged bubble and blub in the glass metal, for feeding machine provides high-quality glass metal by dog-hole.
According to the cell furnace dog-hole that the utility model proposes, also have following technical characterictic:
The height of the stepped appearance weir of cell furnace dog-hole is 200mm～500mm, can stop the impurity sediment in the glass metal in the melting pool to pass through dog-hole effectively, has and separates effect preferably.
The gradient on the slope in cell furnace dog-hole exit is 25 °～75 °, and glass metal slowly can further be clarified homogenizing in the uphill process along the slope, and the bubble eliminated preferably in the glass metal and the clarifying effect of blub are arranged.
The width of cell furnace dog-hole is 600mm～1000mm, increases the cross-sectional area of dog-hole, can slow down the erosion corrosion of glass metal to dog-hole, has also weakened the turbulent flow of glass metal stream simultaneously, provides homogenizing purified glass metal for producing glasswork.
Diapire of the present utility model is a stepped appearance weir, can stop the impurity sediment in the glass metal to pass through dog-hole effectively, and do a slope, can further glass metal be clarified in the exit of dog-hole, discharge bubble and blub in the glass metal, for feeding machine provides high-quality glass metal.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is an A-A sectional view of the present utility model.
The utility model will be further described below in conjunction with accompanying drawing:
With reference to accompanying drawing, the utility model is to support a gap bridge crossbeam 4 by two lateral columns 8,9 to constitute, the diapire of dog-hole 2 is stepped appearance weirs 1, the cavity entrance shape of the dog-hole 2 of Gou Chenging is an inclined to one side rectangular through holes like this, be communicated with the melting pool 5 and the work pool 7 of cell furnace, done a slope 3 in the exit of dog-hole 2.To drop in the melting pool 5 of cell furnace by the admixtion that material side mixes, form glass metal through heat.The gap bridge crossbeam 4 of dog-hole 2 can block the glass metal surface scum, stepped appearance weir 1 can stop the impurity sediment in the glass metal, only allow melting pool 5 interior top-quality middle level glass metals by dog-hole 2, slope 3 along the exit of dog-hole 2 slowly rises to work pool 7 again, glass metal further can be clarified homogenizing, discharge bubble and blub in the glass metal.Provide evenly purified high-quality glass metal for making used in glass products through material road 6 to feeding machine again.The height of stepped appearance weir 1 can stop the impurity sediment in the glass metal to pass through dog-hole 2 at 200mm～500mm, has and separates effect preferably.The gradient on slope 3 is controlled at 25 °～75 °, and glass metal is all had clarifying effect preferably, all can discharge bubble and blub in the glass metal effectively.The width of cell furnace dog-hole is made 600mm～1000mm, increased the cross-sectional area of dog-hole 2, can slow down flow velocity by the glass metal of dog-hole 2, alleviate erosion corrosion to dog-hole 2, prolong the life-span of dog-hole 2, also weakened simultaneously the turbulent phenomenon of glass metal stream, provide homogenizing purified high-quality glass metal for producing glasswork.Established solid basis for making high-quality glasswork.
