Description
Technical field
The utility model relates to a kind of glass production line annealing furnace supplementary unit, especially a kind of D district pressure relief device of sheet glass annealing furnace.
Background technology
The sheet glass annealing furnace is one of visual plant during sheet glass is produced, and it mainly acts on is that glass ribbon 600 ℃ is cooled to 70 ℃ continuously, and with the stress control that produces in the process of cooling in allowed limits.Annealing furnace mainly is divided into heat preservation zone and (comprises A, B, the C district) and non-heat preservation zone (comprise the D district, the Ret district, the F district) two parts, the D district is positioned at the front end of non-heat preservation zone, be used to finish the transition between heat preservation zone and the non-heat preservation zone, what heat preservation zone adopted is the type of cooling that thermal radiation is conducted heat, thereby annealing atmosphere that need be stable, what the Ret district adopted is warm braw forced convection cooled glass (promptly directly with warm braw glass-blowing upper and lower surface), make inside, Ret district produce bigger positive pressure, cooling air has entered kiln body inside, C district by the D district under the effect of air pressure, and influenced the inner annealing atmosphere in C district, cause air turbulence, existing stable thermograde and the anneal environment of the glass ribbon that makes destroyed, temperature control system will produce continuous adjustment, is in a unsure state all the time, and glass quality is produced periodic influence.
The D district all mainly is made of annealing furnace, top frame and cover plate three parts all the time, when the Ret district is very big to the influence of C district, also can come the D district is carried out pressure release by the space of adjusting between the cover plate, but the size in space is not easy control, the pressure release effect is bad, still have a large amount of cooling airs and enter the C district, influence the annealing atmosphere in C district, and because D district temperature is higher, for a long time in this operation danger close.
The utility model content
It is bad in order to overcome existing annealing furnace D district's pressure release effect that the purpose of this utility model is exactly, unhandy defective, and a kind of D district pressure relief device of sheet glass annealing furnace is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of D district pressure relief device of sheet glass annealing furnace, the top frame that comprises lear D district and top, it is characterized in that: top frame is provided with valve seat, the valve seat top is provided with vavle shelf, vavle shelf is provided with one group of rotating shaft, is respectively equipped with a valve plate in each rotating shaft, and each rotating shaft two ends is connected with bearing support on the vavle shelf respectively, rotating shaft one end also is provided with the chuck handle, and the chuck handle is connected with handle bracket on the vavle shelf.
Described vavle shelf is the rectangular frame that is made of four girder steels, evenly is provided with one group of parallel shaft on the symmetrical girder steel of framework, and the rotating shaft in the framework is provided with the rectangle valve plate, and the rectangle valve plate is connected with the rotating shaft axis at the symmetry axis place.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
The normal section that described valve seat connects and composes for up and down two rectangular frames and a pair of trapezoidal web plate and a pair of swash plate is the valve seat of " funnel " shape, and valve seat adopts water conservancy diversion shape structure, avoids gas to produce turbulent phenomenon in exclusion process.
Described one group of valve plate connects and composes closure valve; The limit of adjacent two valve plates closely contacts when closed, and one group of valve plate constitutes the airtight valve of level.
The beneficial effects of the utility model are to have improved the pressure release ability, have reduced the influence of cooling air to the C district; Easy to operate, safe in utilization.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Fig. 1 is a front view of the present utility model;
