Description

Technical Field

[0001] This invention relates to the field of petrochemicals, and in particular to a process and equipment for plugging leaks in oil storage tanks. Background Technology

[0002] Steel welded storage tanks are widely used storage equipment in petrochemical production. Under various influences, oil tanks are prone to leakage. In such cases, leak-sealing devices are needed to fill the leaks and prevent further leakage. Among these methods, adhesive-based leak-sealing is the most widely used because it does not require open flames, thus ensuring oil depot safety. Adhesive-based leak-sealing involves using adhesives to directly or indirectly seal the leak points in oil tanks, pipelines, and other equipment. A key characteristic of this process is that radial pressure must be applied to the sealing plate or wedge during application.

[0003] Currently, the existing process typically involves constructing a cement pile foundation (or utilizing an existing cement pile foundation) next to the leak point in the tank. After the cement pile has fully cured, holes are drilled in the foundation, and a sealing plate or wedge is placed between the tank and the cement pile using metal components. The entire construction process is quite cumbersome, unsuitable for emergency repairs, and poses significant safety hazards.

[0004] Therefore, in order to overcome the shortcomings of existing technologies, it is necessary to develop a process and equipment for sealing leaks in oil storage tanks, which can be used to seal leaks in atmospheric pressure steel oil storage tanks. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a process equipment for plugging leaks in oil storage tanks, which effectively overcomes the defects of the prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0007] An oil storage tank leak sealing process equipment includes a retractable base, the base having a fixed end and a retractable end, and an adjustable magnetic adsorption component and a pressurizing leak sealing component respectively provided on one side of the fixed end and the retractable end.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the base includes a strip-shaped first base and a strip-shaped second base. The first base has a hollow cavity that extends along its length and through one end. One end of the second base extends into the hollow cavity from one end of the first base. The first base constitutes the fixed end, and the second base constitutes the telescopic end.

[0010] Furthermore, the first seat includes a strip-shaped first main body and a cover plate. The first main body has a hollow cavity inside. The first main body is hollow inside and has an open side. The cover plate is detachably installed on the open side of the first main body. The cavity between the first main body and the cover plate forms the hollow cavity.

[0011] Furthermore, the first seat is provided with the pressurized leak-sealing component at one end and the second seat is provided with the magnetic adsorption component at the other end of the first seat.

[0012] Furthermore, the aforementioned pressurized leak-sealing component includes a first screw and a first leak-sealing pressure block connected to one end of the first screw. One end of the first seat and the other end of the second seat are respectively provided with a first screw hole perpendicularly through them. The other end of the first screw passes through the corresponding first screw hole and is screwed together with each other.

[0013] Furthermore, the first main body and the cover plate are respectively provided with a first sliding groove along their respective length directions. The second seat is provided with a strip-shaped first guide hole that passes through both sides along its length direction. A first connecting rod that passes through the first sliding groove on the cover plate and the other end of the first main body is provided through the first guide hole. One end of the first connecting rod is connected to the magnetic adsorption component. The other end of the first connecting rod is provided with a threaded section and is screwed with a first locking nut.

[0014] Furthermore, the first seat is provided with a magnetic adsorption component at one end and the second seat is provided with a pressure sealing component at the other end of the first seat.

[0015] Furthermore, a second connecting rod is vertically inserted through one end of the first seat and the other end of the second seat, respectively. One end of the second connecting rod is connected to the magnetic adsorption component, and the other end of the second connecting rod is provided with a threaded section and screwed with a second locking nut.

[0016] Furthermore, the first main body and the cover plate are respectively provided with second sliding grooves along their respective length directions. The second seat is provided with strip-shaped second guide holes that pass through both sides along its length direction. The other end of the first main body is provided with a second screw hole. The pressure sealing component includes a second screw and a second sealing block connected to one end of the second screw. One end of the second screw passes through the second screw hole and is screwed together with it. The other end of the second screw passes through the second guide hole and the second sliding groove on the cover plate in sequence.

[0017] Furthermore, the aforementioned magnetic adsorption component includes a housing, a first permanent magnet block, and a second permanent magnet block. The housing has a cylindrical cavity in the middle region inside. The second permanent magnet block is installed in the cavity and can rotate along the axial direction of the cavity. One end of the cavity is externally encapsulated with a rotating component connected to one end of the second permanent magnet block. The housing has a mounting groove corresponding to the portion between the cavity and the base. The first permanent magnet block is embedded in the mounting groove.

[0018] The beneficial effects of this invention are: the structural design is simple and reasonable, and it can adapt to the sealing of leak points of different widths through the expansion and contraction of the base. At the same time, the adjustable magnetic adsorption component can facilitate the adsorption and removal of the entire equipment on the surface of the oil tank, making the operation very convenient.

Detailed Implementation

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] Example: Figure 1 , 5 As shown, the oil tank leak sealing process equipment of this embodiment includes a retractable base 1. The base 1 has a fixed end and a retractable end. One side of the fixed end and the retractable end is respectively provided with a magnetic adsorption component 2 with adjustable magnetic force and a pressure sealing component 3.

[0030] In this embodiment, the oil tank sealing equipment is used by adjusting the extension dimensions of the fixed and telescopic ends of the base 1 according to the location and size of the leak. Then, using the magnetic force of the magnetic adsorption component 2, the equipment can be adsorbed onto the steel oil tank. This magnetic force provides the radial pressure required for the sealing process. The pressurized sealing component 3 then tightly seals the leak on the surface of the oil tank. The magnetic force of the magnetic adsorption component 2 can be adjusted (it can be adjusted to either a magnetic or non-magnetic state). In the non-magnetic state, the equipment can be easily transferred and disassembled. In the magnetic state, it can effectively adhere to the surface of the oil tank, providing radial pressure to the pressurized sealing component 3. The overall structural design is simple and reasonable. It can adapt to sealing leaks of different widths through the extension and retraction of the base. At the same time, the adjustable magnetic adsorption component facilitates the adsorption and removal of the entire equipment on the surface of the oil tank, making operation very convenient.

[0031] In this embodiment, depending on the shape, size, and distribution of the leak points on the steel tank, multiple sets of the aforementioned process equipment can be used to tighten multiple plugging plates or plugs separately. Alternatively, multiple sets of the aforementioned process equipment can be used to increase the applied radial pressure on a specific plugging plate or plug.

[0032] In this embodiment, as Figure 4 As shown, the base 1 includes a strip-shaped first seat 11 and a strip-shaped second seat 12. The first seat 11 has a hollow cavity extending along its length and through one end. One end of the second seat 12 extends into the hollow cavity from one end of the first seat 11. The first seat 11 constitutes the fixed end, and the second seat 12 constitutes the telescopic end. The base 1 adopts a split-type structural design. When the size needs to be adjusted, the second seat 12 can be pulled relative to the first seat 11. The first seat 11 and the second seat 12 fit tightly, and the pulling direction is unidirectional, without any "jumping" outside the telescopic direction.

[0033] In a preferred embodiment, the first seat 11 includes a strip-shaped first body 111 and a cover plate 112. The first body 111 has a hollow cavity inside. The first body 111 is hollow inside and has an open side. The cover plate 112 is detachably installed on the open side of the first body 111. The cavity between the first body 111 and the cover plate 112 forms the hollow cavity.

[0034] In the above implementation scheme, in the first seat 11, the first main body 111 adopts a groove-shaped design, and the open side is assembled with the first main body 111 by bolts spaced around the edge of the cover plate 112. The structure of the first seat 11 is simple and easy to install, and it is also convenient to assemble the second seat 12.

[0035] In this embodiment, the pressure-sealing component 3 and the magnetic adsorption component 2 can include at least the following two forms:

[0036] 1) such as Figure 1 , 2 As shown in Figures 3 and 4, one end of the first seat 11 and the other end of the second seat 12 are respectively provided with the pressurized sealing component 3, and the other end of the first seat 11 is provided with the magnetic adsorption component 2.

[0037] In the above scheme 1), a magnetic adsorption component 2 is set in the middle of one side of the base 1, and a pressure sealing component 3 is distributed at each end of one side of the base 1, forming a "one suction and two sealing" design.

[0038] More specifically, the aforementioned pressurized leak-sealing component 3 includes a first screw 31 and a first leak-sealing pressure block 32 connected to one end of the first screw 31. One end of the first seat 11 and the other end of the second seat 12 are respectively provided with a first screw hole perpendicularly passing through them. The other end of the first screw 31 passes through the corresponding first screw hole and is screwed together with the first screw. In use, by turning the first screw 31, the first screw 31 can move the first leak-sealing pressure block 32, moving it closer to or further away from one side of the first seat 11 and the second seat 12. That is, when used on the surface of the oil storage tank, after being attracted and fixed by the central magnetic adsorption component 2, turning the two first screws 31 can bring the two first leak-sealing pressure blocks 32 closer to the two leak points for sealing.

[0039] It should be noted that the other end of the first screw 31 is provided with a square or hexagonal head to facilitate applying torque to rotate it.

[0040] Based on the above scheme 1), the first main body 111 and the cover plate 112 are respectively provided with first sliding grooves along their respective length directions. The second seat 12 is provided with strip-shaped first guide holes extending through both sides along its length direction. A first connecting rod a passes through the first sliding groove on the cover plate 112 and the other end of the first main body 111 through the first guide hole. One end of the first connecting rod is connected to the magnetic adsorption member 2, and the other end of the first connecting rod is provided with a threaded section and screwed with a first locking nut c. The first connecting rod is positioned at the other end of the first main body 111. During the extension and retraction of the second seat 12, the first connecting rod is in the first guide hole and can move relative to the first guide hole, ensuring that the first seat 11 and the second seat 12 can move and extend well relative to each other. Before adsorption, by tightening the first locking nut, the first locking nut and the magnetic adsorption member 2 are "clamped" at the other end of the first seat 11.

[0041] 2) such as Figure 5 As shown, the magnetic adsorption component 2 is provided at one end of the first seat 11 and the other end of the second seat 12, and the pressure sealing component 3 is provided at the other end of the first seat 11.

[0042] In the above scheme 2), a magnetic adsorption component 2 is set at each end of one side of the base 1, and a pressure sealing component 3 is set in the middle of one side of the base 1, forming a "two-adsorption and one-sealing" design.

[0043] More specifically, a second connecting rod b is vertically inserted through one end of the first seat 11 and the other end of the second seat 12. One end of the second connecting rod is connected to the magnetic adsorption component 2, and the other end of the second connecting rod has a threaded section and is screwed with a second locking nut. The second connecting rod is positioned at both ends of the first seat 11. During adsorption, the second locking nut d is tightened, so that the second locking nut, together with the magnetic adsorption component 2, clamps the two sides of the first seat 11. Then, the magnetic adsorption component 2 adsorbs the material, and the leak is sealed by the pressure sealing component 3.

[0044] Based on the above scheme 2), the other side of the first main body 111 and the cover plate 112 are respectively provided with second sliding grooves along their respective length directions. The second seat 12 is provided with strip-shaped second guide holes that penetrate both sides along its length direction. The other end of the first main body 111 is provided with a second screw hole. The pressure sealing component 3 includes a second screw 33 and a second sealing block 34 connected to one end of the second screw 33. One end of the second screw 33 passes through the second screw hole and is screwed together with it. The other end of the second screw 33 passes through the second guide hole and the second sliding groove on the cover plate 112 in sequence. The second screw 33 passes through the second screw hole at the other end of the first main body 111, and the two are screwed together with each other. The sealing tightness of the second sealing block 34 at the leak point can be adjusted by turning the second screw 33. Before sealing the leak, the second seat 12 is stretched and moved relative to the first seat 11 according to actual needs. The second screw 33 is always in the second guide hole, and the second screw 33 moves relative to the second guide hole during the movement of the second seat 12. This ensures that the first seat 11 and the second seat 12 can be well stretched and adjusted in size.

[0045] In a preferred embodiment, the magnetic adsorption component 2 includes a housing 21, a first permanent magnet block 22, and a second permanent magnet block 23. The housing 21 has a cylindrical cavity in the middle region inside. The second permanent magnet block 23 is installed in the cavity and can rotate along the axial direction of the cavity. One end of the cavity is externally encapsulated with a rotating component 24 connected to one end of the second permanent magnet block 23. The housing 21 has a mounting groove corresponding to the portion between the cavity and the base 1. The first permanent magnet block 22 is embedded in the mounting groove.

[0046] In the above implementation scheme, the magnetic force can be adjusted by operating the rotating component 24 to drive the second permanent magnet block 23 to rotate circumferentially in the cavity, as detailed below:

[0047] like Figure 6 As shown, the two ends of the first permanent magnet 22 are set to N pole and S pole respectively. After rotating the second permanent magnet 23, the S pole of one end of the second permanent magnet 23 is brought close to the N pole of the first permanent magnet 22, and the N pole of the other end of the second permanent magnet 23 is brought close to the S pole of the first permanent magnet 22. In this state, the magnetic lines of force of the first permanent magnet 22 and the second permanent magnet 23 are closed in the housing 21, forming a closed magnetic circuit. The magnetic flux outside the housing 21 is zero, and it is in a "non-magnetic" state.

[0048] like Figure 7As shown, the two ends of the first permanent magnet 22 are set to N pole and S pole respectively. After rotating the second permanent magnet 23 by a certain angle, the N pole of one end of the second permanent magnet 23 is close to the N pole of the first permanent magnet 22, and the S pole of the other end of the second permanent magnet 23 is close to the S pole of the first permanent magnet 22. In this state, the magnetic lines of force inside the housing 21 cannot be closed inside it. They must pass through the external medium to form a closed loop and form a closed magnetic path. The housing 21 shows magnetism to the outside and is in a "magnetic" state, so it can be attracted to the surface of the oil tank.

[0049] It should be further explained that: one end of the cavity is closed, and the other end is open, with a rotating component 24 positioned at the open end. The rotating component 24 includes a disc and a strip-shaped knob on one side of the disc. An annular groove can be formed on the inner wall of the cavity, and the second permanent magnet 23 is embedded in the annular groove. The annular groove is used for limiting and guiding, so that the second permanent magnet 23 will not easily detach from the cavity and can rotate and adjust its angle well in the annular groove with the drive of the rotating component 24. In addition, corresponding "ON" and "OFF" markings can be set on both sides of the surface of the housing 21 to indicate the two states of being magnetic or non-magnetic, which is convenient for operators to adjust.

[0050] It should be noted that: Figure 6 and Figure 7 The selected lines in the text all refer to magnetic field lines.

[0051] In this embodiment, both the first permanent magnet block 22 and the second permanent magnet block 23 are made of magnet steel.

[0052] In this embodiment, the ends of the first plugging block 32 and the second plugging block 34 that contact the leak point can be flat, spherical, or conical.

[0053] The entire process equipment utilizes magnetic force to attach the magnetic adsorption component 2 to the steel tank body, and uses magnetic force to provide the radial pressure required in the aforementioned leak repair process. It has a simple structure and is easy to use. It requires no external power source, is unaffected by the operating environment, can be activated at any time, and allows for timely repairs, preventing significant asset losses while also reducing safety hazards.
