Description
Technical Field
The utility model relates to the technical field of float glass manufacturing, in particular to a tin bath with a tin flow circulation blind channel at the bottom of a tail end.
Background
The tin bath is an important device in the float glass manufacturing technology, the inlet end of the tin bath is connected with the melting furnace, and the outlet end of the tin bath is connected with the annealing furnace. The conventional tin bath body is a rectangular space formed by the bottom of the tin bath and the side walls, the tin bath body is filled with tin liquor, the glass ribbon floats on the tin liquor as a supporting and floating medium, the lower surface of the glass ribbon is contacted with the tin liquor, the purity of the tin liquor has great influence on the glass quality, and especially, tin ash is easily accumulated in a triangular area of the side walls at the outlet of the tin bath.
When the float glass ribbon with the narrow section of the tin bath is pulled by the roller way to advance, the tin liquid below the glass ribbon can be driven to flow towards the outlet end of the tin bath, and when the tin liquid flows to the outlet end of the tin bath and touches the end wall of the lip brick, the tin liquid sinks to flow back upwards, the tin ash in the middle area cannot flow to the edge part, and the tin ash is accumulated in the triangular area below the glass plate, so that defects such as glass tin dipping and the like are easily caused, and the yield and quality of the glass are affected. In practical operation, a worker is required to regularly stretch a long flat wood strip or a packing steel strip into the tin bath from two sides of the tin bath, and the long flat wood strip or the packing steel strip is drawn to drive tin liquid and tin ash to flow to the edges, and then the tin liquid and the tin ash are sucked into a small ear pond by a linear motor or collected into a large ear pond by a rotating wheel. Obviously, this manual method is inefficient, has poor results, can only partially reduce the number of tin defects under the ribbon, and can introduce additional contamination. In addition, some ash removal devices are proposed.
The utility model application publication No. CN219670354U discloses a device for blowing tin ash in the middle area to two sides by using a blowing pipe, and attempts to solve the problem that the tin ash in the middle does not flow. According to the method, the air blowing pipe is additionally arranged in a narrow space, so that the risk of surface scratch and even plate breakage caused by the fact that the glass belt touches foreign matters is greatly increased. The utility model application with publication number CN117623594A discloses a combination mode of a linear motor and a small ear pool, wherein each ear pool is provided with a linear motor, the electromagnetic force of the linear motor is utilized to attract tin liquid and floating tin ash into the small ear pool, and clean tin liquid is refluxed into a tin tank after filtration. The method has the advantages that the tin liquor flowing is short circuit circulation, the action range is limited, tin ash in the range of about 1 meter close to the side wall of the tin bath can only be attracted into the small lug pond, the width of the tin bath is usually more than 5 meters, so that the tin ash in the middle of the tin bath is at least more than 3 meters beyond the action range, the tin ash in a triangular area below the glass ribbon at the center position of the tin bath cannot be attracted by the electromagnetic force of the linear motor, and the tin ash in the middle of the tin bath is required to be brought to the side part by relying on natural tin liquor. In addition, the mechanical slag removing machine for the large lug pool is also provided, and tin ash is collected into the large lug pool by means of a graphite rotating wheel, so that the method has a smaller application range and has larger dependence on natural tin liquid flow. The utility model application with publication number CN218478675U discloses a device for cleaning tin ash by arranging a second linear motor, the second linear motor of the utility model has larger mechanical structure volume, occupies the place where the tail of the tin bath must be left, and brings great risk, and the place is an emergency station for handling the glass ribbon broken plate accident, and the importance of the second linear motor is not inferior to that of a fire-fighting channel and the second linear motor is not occupied. The utility model application of publication CN206799422U discloses a way to provide a deflector at the end of the tin bath in order to deflect the natural tin flow through the deflector from the middle to both sides, but since float glass production technology has been developed to be wide, the natural tin flow is particularly weak, so to speak, almost no flow is induced. Besides, there is a short circuit circulation between the inlet and the outlet of the small ear tanks on two sides, and the short circuit circulation can promote the cleaning of tin ash near the side wall to a certain extent, but in the scheme, the short circuit circulation between the inlet and the outlet of the small ear tanks is blocked by the guide plate, and clean tin liquid flowing out of the small ear tanks is forced to flow back to the upstream only, so that the cleaning effect of tin ash near the side wall is affected, and more importantly, the problem of cleaning tin ash near the center position of the wide tin tank cannot be solved in the same way. The application of the publication CN218841940U discloses another way to try to direct the natural tin flow to the edge, which is expected to improve the working effect of the large-ear pool mechanical slag-raking machine, but as mentioned before, the natural tin flow is already very weak and does not generate enough tin flow to direct the tin ash to the edge, and almost no flow is led. According to the design of lug pools at two sides of the large lug pool, the large lug pool does not have a tin liquid circulation loop, and only the graphite runner is used for collecting tin ash floating on the surface of the tin liquid at the edge.
How to achieve cleaning of tin ash near the center of a wide tin bath without adding additional equipment or instruments is a matter of urgent need in the art.

According to the utility model, the dark channel 6 is arranged at the bottom of the tin bath and forms a tin flow circulation channel with the tin liquid at the outlet end wall 3 of the tin bath, the filtered controlled tin liquid flow of the lug baths at two sides is guided to the vicinity of the central shaft of the tin bath 1 from the edge, and then the tin liquid flows out from the central position of the outlet end wall 3 of the tin bath from bottom to top, so that the tin liquid containing tin ash is driven to automatically flow to the edge, and the tin ash cleaning effect near the central position of the wide tin bath is enhanced.
As shown in fig. 1-3, the present utility model provides a first implementation manner of a tin bath with a tin flow circulation dark channel at the bottom of the tail end, in this embodiment, the dark channel 6 is in a bifurcated structure, and includes two branch channels 9 and a bus channel 10, wherein the inlets of the two branch channels 9 are respectively connected with the outlets of the small ear pools 2 at two sides, the outlets of the two branch channels 9 are both connected with the inlets of the bus channel 10, and the outlets of the bus channel 10 are communicated with tin liquid in the tin bath 1.
