Description

Technical Field

[0001] The utility model relates to the technical field of floating discs, in particular to a sealing mechanism for a fully liquid-contacted inner floating disc. Background Art

[0002] The floating plate is an energy-saving and environmentally friendly device that is covered on the liquid surface and rises and falls with the liquid level of the storage tank through buoyancy. In order to reduce the volatilization of the medium in the storage tank, reduce losses, save energy, and protect the environment, this internal floating plate is added to the storage tank. The storage tank saves energy and protects the environment by installing a floating plate to seal the stored medium and reduce the temperature of the medium. However, the existing floating plate may deviate during the lifting process. For example, a Chinese patent discloses "a high-compensation fully liquid-connected floating plate", and its application number is: "202320459830.5". It supports the oil-resistant and anti-aging film through a support plate. The oil-resistant and anti-aging film covers the oil and gas volatilization range and plays a sealing role. The metal elastic plate group has edge compensation under various working conditions, smooth up and down transportation, good centering, and strong static conductivity.

One end of the tank body 1 is fixedly connected with a retraction box 8 for retracting the steel wire rope 9. The steel wire rope 9 is located on the side surface of the guide wheel 11 to reduce friction. The steel wire rope 9 and the conveying hose 4 both pass through the top plate 2. The right surface of the tank body 1 is fixedly connected with a support plate 7 for supporting the retraction box 8. The retraction box 8 is fixedly connected to the upper surface of the support plate 7. The front surface of the tank body 1 is fixedly connected with an inlet and outlet pipe 5 for adding or discharging liquid into or out of the tank body 1. The side surface of the inlet and outlet pipe 5 is provided with a valve 6 for controlling the on and off of the inlet and outlet pipe 5. The inlet and outlet pipe 5 is connected with the tank body 1, and the valve 6 is located directly in front of the tank body 1.

[0025] Working principle: The floating plate 12 interacts with the liquid in the tank body 1 through the float 16 on its lower surface to achieve the function of rising and falling with the liquid level. When the liquid level rises, the float 16 is acted upon by the buoyancy and drives the floating plate 12 to rise; conversely, when the liquid level drops, the floating plate 12 drops, and the side surface of the floating plate 12 is fixed with a limit block 14, and the limit block 14 slides in the limit groove 13 on the inner wall of the tank body 1, ensuring the stability of the floating plate 12 during the lifting process and preventing it from deflecting or tilting. The floating plate 12 is connected to the retraction box 8 through a wire rope 9. When the liquid level rises but the buoyancy is small, the motor inside the retraction box 8 is started to rotate and retract the wire rope 9; when the floating plate 12 drops, the retraction box 8 releases the wire rope 9, allowing the floating plate 12 to drop freely, which can maintain the smooth movement of the floating plate 12. 9 slides on the side surface of the guide wheel 11, and the rotation of the guide wheel 11 reduces the friction between the wire rope 9 and the support frame 10, making the movement of the wire rope 9 smoother. The support frame 10 provides a stable support for the guide wheel 11 to ensure that it will not shift or deform during operation. The air cooler 3 generates cold air and transports the cold air to the cavity 15 inside the floating plate 12 through the delivery hose 4. The cold air circulates in the cavity 15 to reduce the temperature of the floating plate 12 and its surrounding environment. Since the floating plate 12 is in direct contact with the liquid in the tank body 1, the cooling effect of the cold air on the floating plate 12 will be indirectly transmitted to the liquid, thereby achieving cooling of the liquid in the tank body 1. The inlet and outlet pipes 5 are used to add or discharge liquid into the tank body 1, and the valve 6 controls the on and off of the inlet and outlet pipes 5, which is convenient for filling, draining or sampling the tank body 1.
