Description

Technical Field

[0001] The utility model relates to the technical field of floating discs, and more specifically, to a floating disc for a storage tank that prevents clamping of the disc. Background Art

[0002] The internal floating disc in a storage tank is an energy-saving and environmental protection device that covers the liquid surface and rises and falls with the liquid level of the storage tank by buoyancy. To reduce the volatilization of the medium in the storage tank, reduce losses, save energy, and protect the environment, this internal floating disc is added to the storage tank. The storage tank installs the floating disc to seal the stored medium and reduce the medium temperature to achieve the effects of saving energy and protecting the environment. This device is widely used in petrochemical units, major oil companies such as Sinopec and PetroChina, refineries, port terminals, transportation, power plants, and the logistics departments of the military across the country.

[0003] A Chinese utility model patent with the application number CN202222475851.4 discloses a floating disc for a storage tank that prevents clamping of the disc, including a tank body. A base is provided at the inner bottom end of the tank body, and four sleeves are fixedly installed at the top end of the base. A return spring is fixedly installed at the inner bottom end of the four sleeves, and a slider is provided at the top end of the four springs. Although it solves the problem of the floating disc tilting after the oil in the storage tank rises, there will be a gap between the side surface of the floating disc and the storage tank, which will cause the volatilization of the liquid in the storage tank.

[0004] Therefore, it is very necessary to propose a floating disc for a storage tank that prevents clamping of the disc to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that there will be a gap between the side surface of the existing floating disc and the storage tank, which will cause the volatilization of the liquid in the storage tank.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A floating disc for a storage tank that prevents clamping of the disc, including a floating disc. A ring is fixedly connected to the outer side surface of the floating disc. An airbag is detachably arranged on the ring. A plurality of air pipes are symmetrically and fixedly connected to the inner side surface of the airbag. A one-way valve is fixedly connected to the middle of the air pipe. An air release mechanism is arranged on one of the air pipes.

[0008] Further, a plurality of upper clamping plates are symmetrically and rotatably connected to the upper end of the outer side surface of the ring, and a plurality of lower clamping plates are symmetrically and fixedly connected to the lower end of the outer side surface of the ring. A first arc-shaped sliding groove is formed on the outer side surface of the ring. A blocking rod is slidably connected in the first arc-shaped sliding groove. The blocking rod is used to temporarily fix the upper clamping plate to the ring, so as to form a limiting space for the airbag between the upper clamping plate and the lower clamping plate.

[0009] Furthermore, tube grooves for placing air pipes are symmetrically formed on the floating disc, and second arc-shaped sliding grooves are symmetrically formed at the upper end of the circular ring. An arc-shaped baffle for restricting the air pipe in the tube groove is slidably connected in the second arc-shaped sliding groove.

[0010] Furthermore, a second arc-shaped sliding groove communicating with the sinking groove is formed on the floating disc, and an arc-shaped rod is slidably connected in the second arc-shaped sliding groove. The arc-shaped rod located outside the second arc-shaped sliding groove is fixedly connected to the side surface of the arc-shaped baffle, and a spring is fixedly connected between the side surface of the arc-shaped baffle and the floating disc.

[0011] Furthermore, the air release mechanism includes an electric push rod fixedly connected to the air pipe and a plug rod fixedly connected to the output end of the electric push rod. A plug hole for inserting the plug rod is formed in the air pipe.

[0012] Furthermore, the plug rod is L-shaped.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, through the arrangement of the airbag, on the one hand, when disassembling the floating disc, the air in the airbag is released, thereby increasing the distance between both sides of the floating disc and the inner side surface of the storage tank. At the same time, when used in the storage tank, due to the elasticity of the airbag, it can also prevent being stuck in the storage tank.

[0015] 2. In the present utility model, through the cooperative arrangement among the upper clamping plate, the lower clamping plate and the stop rod, it is convenient to limit and install the airbag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , a floating disc for a storage tank that prevents clamping, including a floating disc 1. A ring 2 is fixedly connected to the middle position of the outer side surface of the floating disc 1. An airbag 5 is detachably arranged on the ring 2. A plurality of air pipes 6 are symmetrically and fixedly connected to the inner side surface of the airbag 5. A one-way valve 7 is fixedly connected to the middle of the air pipe 6 and is used to inflate the inside of the airbag 5 when installing the airbag 5. An air release mechanism is arranged on one of the air pipes 6 and is used to release the air in the airbag 5 when disassembling the airbag 5.

[0023] Specifically, as shown in Figure 1 and Figure 4 , a plurality of upper clamping plates 3 are symmetrically and rotatably connected to the upper end of the outer side surface of the ring 2, and a plurality of lower clamping plates 4 are symmetrically and fixedly connected to the lower end. Among them, the inner side surfaces of the upper clamping plates 3 and the lower clamping plates 4 are both arc-shaped. As shown in Figure 4 , a first arc-shaped sliding groove 11 is opened on the outer side surface of the ring 2. A stop rod 12 is slidably connected in the first arc-shaped sliding groove 11. The stop rod 12 is used to temporarily fix the upper clamping plate 3 to the ring 2, so that a limiting space for the airbag 5 is formed between the upper clamping plate 3 and the lower clamping plate 4. After the upper clamping plate 3 is temporarily fixed to the ring 2, by sliding the stop rod 12 to a position close to the hinged end of the upper clamping plate 3 and the ring 2, the rotation of the upper clamping plate 3 can be restricted. In addition, when the airbag 5 deflates, the upper clamping plate 3 and the lower clamping plate 4 are also at a distance from the inner side surface of the storage tank, preventing the airbag 5 from getting stuck.

[0024] Specifically, as shown in Figure 1 and Figure 2 , pipe grooves 10 for placing the air pipes 6 are symmetrically opened on the floating disc 1. During installation, the air pipes 6 are placed in the pipe grooves 10. Second arc-shaped sliding grooves 14 are symmetrically opened at the upper end of the ring 2. Arc-shaped baffles 16 for restricting the air pipes 6 in the pipe grooves 10 are slidably connected in the second arc-shaped sliding grooves 14. By pushing the arc-shaped baffles 16 to block the second arc-shaped sliding grooves 14, the up and down movement of the air pipes 6 can be restricted.

[0025] Specifically, as shown in Figure 1 and Figure 2As shown, in order to prevent the arc baffle 16 from shaking when moving, a second arc chute 14 connected to the sunken groove 13 is opened on the floating plate 1, and an arc rod 15 is slidably connected in the second arc chute 14. The arc rod 15 located outside the second arc chute 14 is fixedly connected to the side of the arc baffle 16, and a spring 17 is fixedly connected between the side of the arc baffle 16 and the floating plate 1. The setting of the spring 17 can give the arc baffle 16 a certain thrust to prevent the release of the restriction on the trachea 6.

[0026] Specific, combined Figure 1 As shown, the deflation mechanism includes an electric push rod 8 fixedly connected to the trachea 6 and a plug rod 9 fixedly connected to the output end of the electric push rod 8. A plug hole for plugging the plug rod 9 is opened on the trachea 6. The plug rod 9 is controlled to move up and down by the electric push rod 8, thereby realizing the opening and blocking of the plug hole, which is convenient for deflation of the airbag 5.

[0027] Specific, combined Figure 1 As shown, the plug rod 9 is L-shaped.

[0028] Installation method: outside the storage tank, first connect the one-way valve 7 through the air pump to fill the airbag 5 with air, then push the arc baffle 16 to compress the spring 17, and then align the air pipe 6 with the pipe groove 10 for installation. After the installation is completed, release the arc baffle 16. Under the action of the compression spring 17, it will cover the air pipe 6 to form a limit for the air pipe 6. Then rotate the upper clamping plate 3 so that the inner side of the upper clamping plate 3 fits the airbag 5. After the fit is completed, push the baffle 12 so that the baffle 12 fits the upper clamping plate 3 to complete the limit of the upper clamping plate 3, so that the upper clamping plate 3 and the ring 2 are in a relatively fixed state. After the installation is completed, put the floating plate 1 into the storage tank as a whole;

[0029] When the floating plate 1 is in use, the airbag 5 has a certain elasticity to prevent it from getting stuck in the storage tank;

[0030] When the floating plate 1 is disassembled, the electric push rod 8 is controlled to extend, driving the plug rod 9 to move upward to deflate the air bag 5.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
