Description

A fully liquid-connected internal floating plate

Technical Field

The invention relates to the technical field of floating plates, in particular to a fully liquid-connected internal floating plate.

Background Art

The fully liquid-contacted internal floating plate is installed inside the storage tank through an installation shaft. A top cover made of special lightweight material is placed according to the cross-sectional size of the storage tank. It can move up and down as the number of objects inside increases or decreases, playing a limiting role as an internal floating plate; the internal floating plate floats on the liquid surface, leaving no evaporation space for the liquid phase, which can reduce evaporation losses by 95% to 98%; in addition, the floating plate blocks the air and the stored liquid, reducing air pollution while reducing the degree of fire hazards; finally, since there is no gas space on the liquid surface, the vibration generated during transportation is reduced, preventing the stored liquid from hitting the inner wall of the tank or increasing the internal pressure, reducing the corrosion of the tank top and tank wall, and extending the service life of the tank.

The existing fully liquid-contacted internal floating plate contacts the inner wall of the storage tank by the edge of the floating plate during use, thereby achieving a barrier to the liquid in the storage tank and achieving a sealing effect to solve the problem of liquid volatilization. However, the current fully liquid-contacted internal floating plate contacts the edge of the storage tank when the storage tank is not filled, resulting in friction between the outer side of the floating plate and the edge of the storage tank during the liquid filling process. Over time, this will cause increased wear on the edge of the floating plate, resulting in extended wear of the seal at the edge of the floating plate, and further reduced sealing effect. Therefore, we urgently need a fully liquid-contacted internal floating plate to solve the above problems.

A hydraulic cylinder 84 is fixedly installed on the circular groove 81 and located outside the placement through hole 82. A collar 85 is fixedly installed on the output end of the hydraulic cylinder 84. The push-out plate 83 is also fixedly connected to the collar 85, and a sealing ring 86 is fixedly installed on the collar 85.

A support column 9 is fixedly installed on the floating plate 1 3 .

The collar 85 is made of a soft material and can be pushed outwards, so that the sealing ring 86 can be tightly sealed with the inner wall of the tank, and the collar 85 is in close contact with the inner wall of the circular groove 81. When the collar 85 reaches the push-out limit, the collar 85 is still located in the circular groove 81.

When the fully liquid-connected internal floating plate is working, when the storage tank starts to be filled with liquid, the support column 9 is located in the storage tank and contacts the bottom wall of the storage tank, separating the floating plate from the bottom wall of the storage tank. When the liquid gradually increases, the floating plate moves upward with the liquid. When the floating plate moves to the predetermined liquid level in the storage tank, the driving block 62 in the linear guide rail 61 in the installation barrel 1 moves downward and moves the connecting plate 63 downward, so that the water inlet hole 64 on the connecting plate 63 contacts the liquid, and the liquid continuously flows into the installation barrel 1 through the water inlet hole 64. , the liquid level in the installation barrel 1 continues to rise and enters the water tank 69 through the transmission pipe 68.

When the water in the water bag 103 props up the water bag 103, the moving plate 106 in the L-shaped partition 101 will slide through the slide rail. When the moving plate 106 moves, the driving slider 108 on the ejector rod 107 docks with the driving guide rail 105 and slides outward. When the ejector rod 107 moves outward, the driving motor 79 drives the transmission rod 710 to drive the hydraulic cylinder 1 711 to flip upward and drive the ejector rod 2 75 to move upward. When the bottom end of the ejector rod 2 75 fits the inner wall of the slide rail 1 72, the ejector rod 107 drives the driving slider 108 to move and limits the bottom end of the ejector rod 2 75.

When the ejection rod 75 moves upward, the triangular plate 77 on the ejection rod 75 will push out the ejection plate 83 placed in the through hole 82. When the ejection plate 83 is pushed out, the collar 85 will be pushed out, and the collar 85 will be pushed out in cooperation with the hydraulic cylinder 84. When the collar 85 is pushed out, the sealing ring 86 will be in tight contact with the inner wall of the storage tank to complete the sealing.
