The inner floating plate is a floating top cover floating on the liquid surface of the oil tank and rising and falling with the oil products. The use of this inner floating top cover to cover the liquid surface is currently recognized as the most ideal, most economical and simple method to reduce the evaporation loss of oil products. It can reduce the volatilization loss of the medium and prevent air pollution. The built-in floating plate can reduce the volatilization loss during the storage of oil, reduce safety hazards and reduce environmental pollution.

[0003] The floating blocks used in the existing single-disc storage tank inner floating plate are fixed by welding, which is not convenient for later maintenance and replacement, difficult to disassemble, and not convenient for adjustment when using different oil products. It is troublesome to use. At the same time, the air holes are embedded in the plane of the inner floating plate. Since the air holes are close to the material liquid surface, more volatile gases are taken back when the gas is discharged, causing waste. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a floating plate in a single-plate storage tank, including a plate body 1 with an opening at the top, a mounting frame 2 is fixedly installed inside the plate body 1, a buoy 3 is movably installed on the inner side of the mounting frame 2, a floating plate cover 4 is movably installed on the top of the plate body 1, a fixing bolt 5 connected to the mounting frame 2 is threadedly installed on the top of the floating plate cover 4, and an exhaust assembly 7 is fixedly installed on the top of the floating plate cover 4.

[0024] By providing a mounting frame 2 located inside the disc body 1, the buoy 3 is installed and limited in a corresponding manner and cooperates with the floating disc cover 4 to connect and press the disc body 1, so that the buoy 3 can be easily installed and disassembled, which is convenient for later repair and maintenance, and is also convenient for adjusting the buoyancy according to the oil product. By providing an exhaust component 7, when the pressure of the oil-gas mixture in the oil tank accumulates and rises to a threshold, the exhaust component 7 is lifted up to discharge outwards, and then the exhaust component 7 is dropped back and sealed again, so that part of the oil-gas mixture is adsorbed and recovered in contact with the liquid surface, effectively reducing the discharge of oil and gas to the outside, and improving energy saving and environmental protection.

[0025] like Figure 3 As shown, the mounting frame 2 includes an outer fixing ring 21, a docking ring 22 and an inner fixing ring 23. The outer fixing ring 21, the docking ring 22 and the inner fixing ring 23 are fixedly connected to the inner side of the disc body 1 from the outside to the inside in sequence. A connecting rib 24 arranged in a ring shape is fixedly connected between the outer fixing ring 21, the docking ring 22 and the inner fixing ring 23. A limiting groove 25 with a top opening is provided inside the outer fixing ring 21, the docking ring 22 and the inner fixing ring 23. The buoy 3 is movably connected to the inner side of the limiting groove 25. A connecting hole 26 is provided on the top of the outer fixing ring 21.

[0026] The buoy 3 is installed by being inserted into the limit slots 25 which are staggered between the outer fixing ring 21 and the docking ring 22 and between the docking ring 22 and the inner fixing ring 23, so that the buoy 3 can be flexibly installed and disassembled, which is convenient for adjusting the buoyancy according to the oil quality and facilitating subsequent repair and maintenance.

[0027] like Figure 5As shown, the exhaust assembly 7 includes an exhaust pipe 71, which is fixedly connected to the top of the floating plate cover 4, a fixing frame 72 is fixedly connected to the outer side of the exhaust pipe 71, a slide plate 73 is slidably connected to the inner side of the fixing frame 72, an inner sealing ring 74 is fixedly installed at the bottom of the slide plate 73, and an outer sealing ring 75 corresponding to the inner sealing ring 74 is fixedly installed on the upper part of the inside of the exhaust pipe 71.

[0028] When the accumulated pressure of the oil-gas mixture rises to a threshold value, the slide plate 73 is lifted up, so that the slide plate 73 drives the inner sealing ring 74 to slide upward along the fixed frame 72, so that the top of the exhaust pipe 71 is opened to discharge the leaked air. After that, the slide plate 73 drives the inner sealing ring 74 to slide down due to gravity, so that the inner sealing ring 74 fits the inner side of the outer sealing ring 75 for sealing. The oil and gas in the oil-gas mixture are blocked by the fan-shaped disk 76 during the stroke, so that part of the oil and gas return to the oil liquid surface for adsorption and recovery, thereby reducing the external discharge of oil and gas and improving energy saving.

[0029] like Figure 3 As shown, the limiting slot 25 is divided into symmetrically arranged sector areas by connecting ribs 24 .

[0030] The distances between the outer fixing ring 21 , the docking ring 22 and the inner fixing ring 23 are set equal.

[0031] The limiting groove 25 is divided into sector-shaped areas by connecting the ribs 24, so as to facilitate the balanced and stable installation and placement of the buoy 3.

[0032] like Figure 4 As shown, a pressing block 6 is fixedly installed at the bottom of the floating plate cover 4. The pressing block 6 is a sponge board, and the pressing block 6 is arranged to fit the top of the buoy 3.

[0033] The pressing block 6 is pressed on the top of the buoy 3 after being installed with the floating plate cover 4, thereby ensuring the position of the buoy 3 and ensuring the installation stability.

[0034] like Figure 2 As shown, exhaust passages are provided inside the disc body 1 and the floating disc cover plate 4, and the exhaust assembly 7 is connected to the exhaust passages.

[0035] The exhaust passage is connected to the exhaust component 7 so that the oil-gas mixture is discharged from the exhaust component 7 .

[0036] like Figure 4 As shown, a sealing strip 8 is movably engaged on the outer side of the disk body 1 .

[0037] The sealing strip 8 is provided to ensure the sealing effect of the disc body 1 in the oil tank.

[0038] The following is a detailed description of the working principle of the floating plate in the single-plate storage tank.

[0039] like Figures 1 to 5As shown, by selecting the corresponding buoy 3 according to the oil product, the buoy 3 is respectively inserted and installed above the limit slots 25 staggered between the outer fixing ring 21 and the docking ring 22 and between the docking ring 22 and the inner fixing ring 23, and after the buoy 3 is symmetrically installed, the floating plate cover 4 is inserted along the top of the plate body 1 so that the floating plate cover 4 is attached to the top of the mounting frame 2, so that the position of the floating plate cover 4 corresponds to the connection hole 26, and the floating plate cover 4 is connected to the plate body 1 by using the fixing bolts 5 to pass through the floating plate cover 4 and connect it to the connection hole 26. The connection is fixed, so there is no need to disassemble, maintain and adjust the float 3. When the gas pressure of the oil-gas mixture accumulates and rises to a threshold value during use, the slide plate 73 is lifted up, so that the slide plate 73 drives the inner sealing ring 74 to slide upward along the fixing frame 72, so that the top of the exhaust pipe 71 is opened to discharge the leaked gas. After that, the slide plate 73 drives the inner sealing ring 74 to slide down due to gravity, so that the inner sealing ring 74 fits the inner side of the outer sealing ring 75 for sealing. The oil and gas in the oil-gas mixture are blocked by the fan-shaped disk 76 during the stroke, so that part of the oil and gas flows back to the oil liquid surface for adsorption and recovery.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
