Description

Technical Field

[0001] The utility model belongs to the technical field of float glass production, and particularly relates to a tin bath for manufacturing float glass. Background Art

[0002] The forming of float glass is mainly completed in a tin bath. The tin bath is a trough for containing a floating medium, mainly composed of refractory materials and a steel shell. The refractory materials are in direct contact with the floating medium, molten tin. The periphery of the refractory materials is supported by the steel shell. For the existing float glass tin bath, after long-term use, the temperature inside the tin bath will rise higher and higher. Therefore, the steel shell of the tin bath must be effectively cooled to operate normally. The traditional cooling method generally blows air into the air duct under the steel shell through a blower, and cools the steel shell through multiple branch pipes. The air-cooling method has a poor cooling effect on the tin bath, cannot meet the use requirements, and requires a large amount of civil engineering work such as building a dedicated air duct and a fan room. At the same time, the cooling fan must have sufficient power. When the fan operates, on the one hand, the generated noise is relatively large, and on the other hand, the cooling air will cause a large amount of dust in the workshop, and the cooling fan is prone to failure, thereby increasing the temperature of the bottom steel plate of the trough.

[0003] For this reason, a float glass tin bath with the publication number of "CN218931943U" relates to the field of float glass, including a trough body and a cooling mechanism. The trough body is located inside the cooling mechanism. A support strip is fixedly connected to the inner wall of the cooling mechanism. A water-permeable box is arranged inside the cooling mechanism. The water-permeable box is located on the upper surface of the support strip. The water-permeable box is located above the trough body. A chiller is arranged on one side of the cooling mechanism. During use, the chiller respectively uses the first water supply pipe and the second water supply pipe to cooperate with the first communication pipe and the water delivery mechanism to convey the cooled liquid into the inside of the cooling mechanism to cool the trough body. The drainage box cooperates with the drain pipe and the return pipe to convey the used water back into the inside of the chiller, and the chiller cools the circulating cooling water to ensure that the temperature of the circulating cooling water will not rise higher and higher as much as possible, thereby replacing the traditional blower cooling method and being able to meet the cooling requirements of the tin bath.

[0004] However, for the above float glass tin bath, although the water pipe can convey the liquid inside the water collecting tank into the inside of the conical head and then spray the water out through the spray holes to cool the bottom of the trough body, the following obvious defects still exist during the use process: the above-mentioned method cools the float glass by spraying water on the glass, and since water marks will remain when water is directly sprayed on the surface of the float glass, it is necessary to dry and remove the water marks through a drying mechanism. The cooling of this kind of tin bath increases the technological process of the float glass and will affect the working progress of the float glass. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a tin bath for manufacturing float glass, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A tin bath for manufacturing float glass, including a tin bath, and an outer protection frame outside the tin bath for protecting the tin bath and collecting gas and cooling inside the tin bath in cooperation with a water tank. On both sides inside the outer protection frame, there are air outlet plate members for sucking external air and blowing it into the tin bath for cooling. At positions corresponding to both sides outside the tin bath of the air outlet plate members, there are evenly arranged air inlet hole grooves for allowing air to enter the tin bath. At positions corresponding to both sides of the top inside the outer protection frame on the upper end face of the air outlet plate members, there are high-pressure water spraying strip plates for spraying water to cool the incoming air and connected to the water tank through pipes. A water recovery tank for interconnecting and recovering water is opened at the bottom between the outside of the tin bath and the inside of the outer protection frame. One end of the water recovery tank is connected through a water pipe to a water return pump installed on one side outside the water tank.

[0007] Preferably, at positions corresponding to both sides outside the tin bath of the air outlet plate members, there are evenly arranged air outlet short pipes extending obliquely downward. The other side of the air outlet plate member is equally spaced and penetrated by filter cooling fans arranged on both sides outside the outer protection frame, which can make the external air first enter the inside of the outer protection frame for cooling with cold water and then enter the tin bath to cool the float glass.

[0008] Preferably, on the upper ends of both sides outside the tin bath, there are inclined surfaces for blocking and slowing down the falling of the sprayed water. Part of the falling water can be blocked from flowing into the tin bath through the air inlet hole grooves.

[0009] Preferably, a high-pressure water pump is provided inside the water tank through a partition. The output end of the high-pressure water pump is connected through a water pipe to the high-pressure water spraying strip plates on both sides inside the outer protection frame, spraying water to cool the incoming external gas and then entering the tin bath to cool the float glass.

[0010] Preferably, the water recovery tank is connected through a horizontal guiding pipe. The output end of the water return pump is connected to a water return pipe member, and the water return pipe member is connected through the side of the water tank to recover water, so that the water sprayed to cool the gas can be recovered.

[0011] Preferably, the input end of the high-pressure water pump is connected to a water suction pipe member. A water storage cavity is formed below the partition provided inside the water tank. One end of the water suction pipe member extends through to the bottom end inside the water storage cavity to realize the storage and recovery of water.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: For the tin bath for manufacturing float glass, through the cooperation of the air outlet plate members inside the outer protection frame, the inclined air outlet short pipes on the air outlet plate members, the air inlet hole grooves on both sides of the tin bath, the high-pressure water spraying strip plate, the filtering cooling fan, and the baffle plate, the filtering cooling fan can draw the external air into the cavities between the outer protection frame and both sides of the tin bath. And the water conveyed to the high-pressure water spraying strip plate is sprayed downward to cool the gas entering the cavity. The cooled gas enters the interior of the tin bath through the air inlet hole grooves, and then the float glass in the tin bath can be cooled in a wrapping manner, thus avoiding the problem that water marks remain on the glass after water spraying and cooling and need to be dried again. And by using the baffle plates at the upper ends of both sides outside the tin bath, the water sprayed downward can be blocked to one side, reducing the water sprayed on the surfaces of the float glass in the air inlet hole grooves on both sides outside the tin bath, and further improving the production efficiency of float glass.

[0013] Through the recovery water tank arranged at the bottom of the cavity between the outer protection frame and the tin bath, and the water return pump connected to the recovery water tank, and the water return pump is connected to the water storage cavity, the water sprayed by the high-pressure water spraying strip plate flows downward and enters the interior of the recovery water tank, and only enters the recovery water tank after filtering out impurities and foreign matters by the filter plate. At the same time, the water return pump pumps out the water and conveys it to the middle of the water storage cavity through the water return pipe member, thereby enabling the effective recycling of water and avoiding waste of water resources.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a tin bath for manufacturing float glass, including a tin bath 1, and an outer protection frame 3 outside the tin bath 1 for protecting the tin bath 1 and collecting gas and cooling the inside of the tin bath 1 in cooperation with a water tank 2. The outer protection frame 3 is used to protect the tin bath 1 and has an effect of heat preservation for the tin bath 1. The bottom of the outer protection frame 3 is provided with a horizontally installed bottom plate, and the tin bath 1 is also installed at the end of the horizontally installed bottom plate and is located inside the outer protection frame 3. On both sides inside the outer protection frame 3, there are air outlet plate members 4 for sucking external air and blowing it into the tin bath 1 for cooling, so that the air sucked by the filtration cooling fan 10 enters the air collection cavity inside the air outlet plate members 4 for collection. At positions corresponding to both sides outside the tin bath 1, the air outlet plate members 4 are evenly provided with air inlet hole grooves 5 for allowing air to enter the tin bath 1, so that the air in the air outlet plate members 4 enters the tin bath 1 through the air inlet hole grooves 5 after being output through the air outlet short pipes 9 to cool the float glass by air cooling. At positions corresponding to both sides of the top end inside the outer protection frame 3 on the upper end face of the air outlet plate members 4, there are high-pressure water spraying strip plates 6 for spraying water to cool the incoming air and connected to the water tank 2 through pipes, so that water is sprayed downward through the high-pressure water spraying strip plates 6 to cool and cool the incoming gas. A water recovery tank 7 for recovering water in a mutually communicating manner is opened at the bottom side between the outside of the tin bath 1 and the inside of the outer protection frame 3, and a strip-shaped filter plate for filtering water is provided at the port of the water recovery tank 7. The water recovery tank 7 is opened at both ends of the horizontally installed bottom plate and is designed as a communicating structure, which can recover the water sprayed downward on both sides to prevent it from entering the tin bath 1 through the air inlet hole grooves 5. One end of the water recovery tank 7 is connected through a water pipe to a water return pump 8 installed on one side outside the water tank 2, which can extract and recover the water cooled by the air to the water tank 2 for reuse.

[0021] The air outlet plate member 4 is evenly provided with air outlet short pipes 9 extending obliquely downward at positions corresponding to both sides outside the tin bath 1, and the air outlet ports of the air outlet short pipes 9 correspond to the air inlet hole grooves 5, which is beneficial for the cooled air to enter the tin bath 1 to cool the float glass. The front and rear ends of the outer protection frame 3 and the tin bath 1 are provided with feeding and discharging ports, which is beneficial for the input and output of the float glass. The other side of the air outlet plate member 4 is equidistantly penetrated by filter cooling fans 10 arranged on both sides outside the outer protection frame 3. The air inlet of the filter cooling fans 10 is provided with filter mesh plates, which can filter the dust of the externally entering air. The upper ends of both sides outside the tin bath 1 are provided with inclined surfaces for blocking and slowing down the falling of the sprayed water. The blocking plate 11 can block the downward sprayed water from the top, and reduce the water from entering the tin bath 1 through the air inlet hole grooves 5.

[0022] A high-pressure water pump 12 is arranged inside the water tank 2 through a partition, which can make the water pumped out by the high-pressure water pump 12 generate a large pressure and spray downward from the high-pressure water spraying strip plate 6 to cool the entering gas. The output end of the high-pressure water pump 12 is connected to the high-pressure water spraying strip plates 6 on both sides inside the outer protection frame 3 through a water pipe. The recovery water tank 7 is connected through a horizontal guiding pipe. The output end of the water return pump 8 is connected with a water return pipe member 13, and the water return pipe member 13 is connected through the side of the water tank 2 to recover the water. The input end of the high-pressure water pump 12 is connected with a water suction pipe member 14. A water storage cavity 15 is formed below the partition arranged inside the water tank 2. One end of the water suction pipe member 14 penetrates and extends to the bottom end inside the water storage cavity 15, which is convenient for pumping out the water inside the water storage cavity 15 and conveying it to be sprayed out from the high-pressure water spraying strip plate 6.

[0023] Specifically, when in use, first, start the filtering air cooler 10 by using an externally set controller. The filtering air cooler 10 sucks in external gas and filters dust, allowing the gas to enter the cavity formed between the outer protection frame 3 and both sides of the tin bath 1. At the same time, the high-pressure water pump 12 is started to pump out the water in the water storage cavity 15 through the water extraction pipe fitting 14. The pumped water is transported through a water pipe to the inside of the high-pressure water spraying strip plates 6 arranged on both sides inside the outer protection frame 3, and the water sprays downward from the high-pressure water spraying strip plates 6 to spray water on the incoming gas for cooling, so that the gas reaches a temperature suitable for cooling the float glass. And the blocking plates 11 arranged at the upper ends of both sides outside the tin bath 1 can block part of the sprayed water, preventing the water sprayed downward from hitting the outer side walls of the tin bath 1 and flowing into the float glass inside the tin bath 1 through the air inlet hole grooves 5. At the same time, the cooled gas enters from both sides inside the tin bath 1 through the air inlet hole grooves 5 to cool the float glass in the tin bath 1 by air cooling, avoiding the phenomenon of watermark residues on the float glass caused by water spraying cooling. Thus, there is no need to perform a drying treatment on the float glass for residual watermarks again, further improving the production efficiency of the float glass. And the water sprayed downward by the high-pressure water spraying strip plates 6 flows into the inside of the recovery water tank 7, and only enters the recovery water tank 7 after filtering out impurities and foreign objects by the filter plate. At the same time, the water pump 8 pumps out the water and transports it through the water return pipe fitting 13 to the middle of the water storage cavity 15, thereby enabling effective recycling of the water and avoiding waste of water resources.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
