DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] like Figure 1-4 As shown, the utility model provides a self-tightening floating roof primary sealing device, including a tank wall 1, a floating roof 2 is installed on the inner side of the tank wall 1, a sealing belt 3 is installed on the outer side of the floating roof 2, a filling material 4 is installed inside the sealing belt 3, and connecting mechanisms 5 are installed on both the upper and lower sides of the sealing belt 3.

[0024] The right end of the sealing belt 3 is fixedly connected to the left side of the floating roof 2 , the inner wall of the tank wall 1 is in contact with the protrusion 515 , and the inner wall of the tank wall 1 is in contact with the top of the support plate 57 .

[0025] The filling material 4 can be sponge or other materials with a certain degree of elasticity. The lower end of the sealing belt 3 is also symmetrically provided with four screw holes 511.

[0026] Through the connecting mechanism 5, the support plate 52 and the receiving plate 510 can drive the floating roof 2 to move, and then squeeze the sealing belt 3 and the filling material 4, so that the sealing belt 3 and the filling material 4 will be deformed after being compressed. At this time, the sealing belt 3 and the filling material 4 can block the gap between the floating roof 2 and the inner wall of the tank. At the same time, the sealing belt 3 and the matching support plate 57 realize double sealing. At the same time, the shapes of the sealing belt 3 and the filling material 4 after extrusion will change, which can be applicable to tanks of different specifications, thereby improving applicability.

[0027] like Figure 3-4As shown, the connecting mechanism 5 includes a fixing plate 51, the bottom end of the fixing plate 51 is fixedly connected to the upper left side of the floating roof 2, a supporting plate 52 is installed on the upper end of the fixing plate 51, and screw holes 53 are symmetrically opened on both sides of the upper end of the supporting plate 52, and screw holes 53 are internally threadedly connected to screw rods 54, and screw holes 55 are symmetrically opened on both sides of the right end of the supporting plate 52, and screw holes 55 are internally threadedly connected to screw rods 56, and a supporting plate 57 is installed in the middle of the upper end of the supporting plate 52, and the bottom of the supporting plate 57 is in the middle. A screw hole 58 is provided in the middle, and a screw rod 59 is connected to the inner thread of the screw hole 58; a receiving plate 510 is fixedly connected to the left side of the lower end of the floating roof 2; screw holes 511 are symmetrically provided on the front and rear sides of the lower end of the receiving plate 510, and screw holes 512 are connected to the inner threads of the screw holes 511; screw holes 513 are symmetrically provided on both sides of the right end of the receiving plate 510, and screw holes 514 are connected to the inner threads of the screw holes 513; and a plurality of groups of protrusions 515 are fixedly installed on the outer wall of the sealing belt 3.

[0028] The support plate 52 and the receiving plate 510 are both in an “L” shape, and the right end of the support plate 52 is fixedly connected to the upper left side of the floating roof 2 .

[0029] The fixing plate 51 is also symmetrically provided with screw holes 1 53 , and the middle of the upper end of the support plate 52 is also provided with screw hole 3 58 .

[0030] The left side of the floating roof 2 is symmetrically provided with a second screw hole 55 and a fifth screw hole 513, and the support plate 57 is arc-shaped.

[0031] The upper end of the fixing plate 51 is fixedly connected to the lower end of the supporting plate 52 , and the bottom end of the receiving plate 510 is fixedly connected to the lower end of the sealing belt 3 .

[0032] The support plate 57 is made of a material with certain bending properties. The top of the support plate 57 is a free end. The top of the support plate 57 will abut against the tank wall 1 of the storage tank, and the support plate 57 will bend to a certain extent, thereby ensuring the sealing with the tank inner wall. At the same time, the protrusion 515 arranged on the sealing belt 3 abuts against the tank wall 1 of the storage tank. By providing multiple protrusions 515, the force on the inner wall of the storage tank can be increased, thereby avoiding large friction resistance.

[0033] The working principle of the self-tightening floating roof primary sealing device is described in detail below.

[0034] like Figure 1-4As shown, when the self-tightening floating roof primary sealing device is used, the support plate 52 can be placed on the fixing plate 51, and then the screw 1 54 and the screw 2 56 can be inserted into the screw hole 1 53 and the screw hole 2 55 in turn and tightened, so that the support plate 52 can be fixed, and then the bottom end of the support plate 57 is aligned with the screw hole 3 58 on the support plate 52, and then the screw 3 59 is inserted into the screw hole 3 58 and tightened, so that the support plate 57 wall is fixed, and the top of the support plate 57 is in contact with the inner wall of the tank wall 1; and when in use, the position of the floating roof 2 changes with the liquid oil in the storage tank. The sealing belt 3 moves with the floating roof 2, and during the movement of the sealing belt 3, it is necessary to ensure that the gap between the floating roof 2 and the inner wall of the tank can be effectively sealed. At the same time, the sealing belt 3 is made of flexible material and is corrosion-resistant and wear-resistant. At the same time, the filling material 4 can be sponge or some other materials with a certain degree of elasticity. The filling material 4 is deformed under the extrusion of the supporting plate and the fixing plate 51, and its maximum cross-section in the horizontal direction becomes larger, so that the sealing belt 3 can stably abut against the inner wall of the tank, thereby ensuring the airtightness of the tank.

[0035] 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.
