Description

Technical Field

[0001] This utility model relates to the field of floating roof technology, specifically to a floating roof drainage structure with a ball. Background Technology

[0002] A floating roof is a floating cover that floats on the surface of liquid in a storage tank or in wastewater treatment, rising and falling with the liquid. The upper surface of the floating roof is exposed to the external environment, while the lower surface is in contact with the liquid surface in the storage tank. During tank cleaning or rainfall, liquid may accumulate on the upper surface of the floating roof, and excessive accumulation can affect its safe operation. Due to the environment in which the floating roof is located, manual cleaning is difficult, and rapid cleaning would consume significant manpower and resources. However, leaving the pipes open for extended periods is detrimental to VOC (volatile organic compound) treatment.

[0003] Given the aforementioned problems, it is necessary to install a device to address the issue of liquid discharge from the surface of the floating roof and to minimize the evaporation of oil and gas caused by opening pipes. Utility Model Content

[0004] This utility model provides a floating roof drainage structure with a ball, which solves the problem of liquid accumulation on the upper surface of the floating roof. The technical solution is as follows:

[0005] A floating sphere drainage structure includes an upper fixed plate, a lower fixed plate, a side wall, a limiting component, and a hollow metal sphere. The upper fixed plate is provided with a guide pipe, and the lower fixed plate is provided with a return pipe, the guide pipe extending into the return pipe. A side wall is provided between the upper and lower fixed plates, the side wall being located outside the return pipe. The guide pipe is open at both ends, the return pipe is open at the upper end and closed at the lower end, and the lower fixed plate has an opening in the area between the return pipe and the side wall. The hollow metal sphere floats at the top opening of the guide pipe, and the movement range of the hollow metal sphere is limited by the limiting component, the limiting component being fixedly installed on the upper fixed plate.

[0006] The upper fixing plate and the lower fixing plate are respectively fixedly installed on the upper and lower surfaces of the floating table body by welding.

[0007] A sealing gasket is provided at the upper opening of the guide tube, and the hollow metal ball is pressed on top of the sealing gasket.

[0008] The diameter of the guide tube is smaller than the diameter of the hollow metal sphere, and its length is smaller than the height of the sidewall.

[0009] The length of the return pipe is less than the height of the sidewall, and the diameter is greater than the diameter of the guide pipe.

[0010] The limiting component includes limiting posts and limiting plates. Multiple limiting posts are provided and are evenly arranged along the same circumference. The diameter of the circumference is slightly larger than the diameter of the hollow metal sphere. The lower end of the limiting post is fixedly installed on the upper fixing plate, and the limiting plate is provided on the limiting post.

[0011] The distance between adjacent limiting posts is less than the diameter of the hollow metal sphere.

[0012] The limiting piece has openings at both ends and passes through two opposing limiting posts.

[0013] The upper end of the limiting post is threaded for installing a nut that locks the limiting plate.

[0014] The average density of the hollow metal sphere is less than that of the liquid.

[0015] The floating disc drainage structure with a ball has a better anti-liquid accumulation effect through the design of the annular cavity structure. The present invention has a simple structure and is easy to install and disassemble. Attached Figure Description

[0020] like Figure 1 As shown, the floating disc drainage structure with a ball includes an upper fixed plate 1, a lower fixed plate 2, a side wall 3, a limiting component, and a hollow metal ball 7. The upper fixed plate 1 is provided with a guide pipe 5, and the lower fixed plate 2 is provided with a return pipe 4. The guide pipe 5 extends into the return pipe 4. A side wall 3 is provided between the upper fixed plate 1 and the lower fixed plate 2, and the side wall 3 is located outside the return pipe 4. The guide pipe is open at both ends, the return pipe 4 is open at the upper end and closed at the lower end, and the lower fixed plate 2 is provided with an opening in the area between the return pipe 4 and the side wall 3. The hollow metal ball 7 floats at the top opening of the guide pipe 5, and the movement range of the hollow metal ball 7 is limited by the limiting component, which is fixedly installed on the upper fixed plate 1. The average density of the hollow metal ball 7 is less than the density of the liquid.

[0021] Combination Figures 2 to 4As shown, the ball-bearing floating disk drainage structure is installed at the through hole on the floating disk body 100. The upper fixing plate 1 and the lower fixing plate 2 are respectively fixedly installed on the upper and lower surfaces of the floating disk body 100 by welding. The side wall 3 is circular, surrounds the inner side of the through hole, and is located between the upper fixing plate 1 and the lower fixing plate 2. The upper end of the side wall 3 is fixedly connected to the upper fixing plate 1, and the lower end is fixedly connected to the lower fixing plate 2.

[0022] A circular guide tube 5 is provided in the middle of the upper fixing plate 1, and the guide tube 5 is designed with openings at both the upper and lower ends. A sealing gasket 6 is provided at the upper opening 14 of the guide tube 5, and the hollow metal ball 7 is pressed on top of the sealing gasket 6. The diameter of the guide tube 5 is smaller than the diameter of the hollow metal ball 7, and the length is smaller than the height of the side wall 3.

[0023] A circular return pipe 4 is provided in the middle of the lower fixed plate 2. The upper end of the return pipe 4 is open and the lower end is closed. The length of the return pipe 4 is less than the height of the side wall 3, and the diameter is greater than the diameter of the guide pipe 5. The lower end of the guide pipe 5 extends into the upper opening of the return pipe 4 and forms an annular cavity through the upper fixed plate 1, lower fixed plate 2, return pipe 4, guide pipe 5 and side wall 3. It has a return-flow channel. The liquid reaches the lower opening 15 of the guide pipe 5 from the upper opening 14, enters the space between the return pipe 4 and the side wall 3 through the gap 16 between the guide pipe 5 and the return pipe 4, and then flows out from the openings 17 around the return pipe 4.

[0024] The limiting component includes limiting posts and limiting plates 13. Multiple limiting posts are evenly arranged along the same circumference, the diameter of which is slightly larger than the diameter of the hollow metal sphere. The lower ends of the limiting posts are fixedly mounted on the upper fixing plate 1. The spacing between adjacent limiting posts is smaller than the diameter of the hollow metal sphere 7, preventing the hollow metal sphere 7 from exiting through the gaps between adjacent limiting posts. In this embodiment, four limiting posts are provided: a first limiting post 8, a second limiting post 10, a third limiting post 9, and a fourth limiting post 11 arranged sequentially.

[0025] The upper end of the limiting post is threaded for installing a nut. The two ends of the limiting plate 13 are provided with openings, which pass through two opposing limiting posts. The top of the limiting post containing the limiting plate 13 is locked by a nut 12. In this embodiment, the limiting plate 13 is movably mounted on the first limiting post 8 and the third limiting post 9. Thus, the hollow metal sphere 7 floats within the space formed by the limiting posts, the limiting plate 13, and the upper fixing plate 1, covering the upper opening of the guide pipe 5.

[0026] When liquid accumulates on the upper surface of the floating roof, the hollow metal ball 7 floats up, guiding the liquid through the channel between the upper and lower fixed plates into the lower part of the floating roof. When there is no liquid accumulation on the upper surface of the floating roof, the hollow metal ball 7 falls down, covering the opening of the guide pipe 5 to form a seal. A channel is formed between the upper and lower fixed plates. When liquid accumulates above the floating roof, it can be guided to the lower part of the floating roof by the floating metal ball. After the liquid on the upper surface of the floating roof is drained, a liquid seal is formed at this position to prevent gas from escaping from the lower part of the floating roof. When the liquid disappears and the liquid seal function is no longer available, the gas generated in this channel will be blocked by the sealing space formed between the hollow metal ball and the upper fixed plate.
