Description

Technical Field

[0001] This invention relates to the field of petrochemical technology, and in particular to a splash-proof disassembly device for the slag discharge port of a vertical oil tank valve. Background Technology

[0002] In industries such as petrochemicals, the valves, slag discharge ports, and filters of vertical oil tanks require regular slag removal and cleaning during daily operation. If slag is not removed in a timely manner, some hard impurities may damage the valve's sealing surface, causing the valve to fail to close tightly and resulting in internal leakage. Excessive impurities can also reduce pipeline flow, increase flow velocity, and increase static electricity. During maintenance, when disassembling plugs and blind flanges, splashing often occurs just before removal, causing environmental pollution and potentially resulting in oil splattering on personnel.

[0003] Currently, some methods to address the splashing problem at the slag discharge port involve adding small valves. However, this increases the number of potential leak points, making daily management more difficult and dangerous. Furthermore, existing protective measures are often ineffective at collecting splashes and are ill-suited to different equipment and working conditions. In addition, there is a lack of effective solutions for sealing issues during maintenance; inserting maintenance tools into the slag discharge port area can easily lead to oil leaks, further increasing environmental pollution and safety risks.

[0004] To address this issue, we propose a vertical oil tank valve slag discharge port anti-splash disassembly device. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a splash-proof disassembly device for the slag discharge port of a vertical oil tank valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A splash-proof disassembly device for a vertical oil tank valve discharge port includes a splash-proof cover, on which a maintenance elongated hole is provided, and a sliding sleeve is slidably connected inside the maintenance elongated hole. A sealing gasket is installed between the inner wall of the maintenance elongated hole and the sliding sleeve.

[0008] The splash shield has two symmetrically arranged mounting cavities and two movable slots, and each movable slot is connected to the mounting cavity corresponding to its position. Each mounting cavity is slidably connected to a pusher frame, and each pusher frame is equipped with a locking mechanism on its side wall, and the locking mechanism is located in the movable slot corresponding to its position. The splash shield is slidably connected to a slot frame, and the slot frame is locked onto the two pushers.

[0009] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, a support tray is slidably connected to the inner bottom wall of the anti-splash cover, the upper end face of the support tray is provided with an inclined surface, and a handle is installed on the side wall of the support tray.

[0010] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, the lower end face of the bearing tray is symmetrically equipped with multiple wedge-shaped strips, and the inner bottom wall of the anti-splash cover is symmetrically provided with multiple wedge-shaped sliding grooves, and each wedge strip is slidably connected in the wedge-shaped sliding groove at the corresponding position.

[0011] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, multiple limiting frames are symmetrically installed on the inner side wall of each installation cavity, each limiting frame has a limiting groove, and multiple limiting blocks are symmetrically installed on each pushing frame. Each limiting block is slidably connected in the corresponding limiting groove.

[0012] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, the locking mechanism includes a threaded column, which is fixedly connected to the side wall of the push frame. The threaded column passes through the moving groove and is threadedly connected to a locking nut.

[0013] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, the anti-splash cover is symmetrically provided with multiple through holes, and each through hole is connected to the corresponding mounting cavity. The slot frame includes two symmetrically arranged side connecting plates. Each side connecting plate has multiple U-shaped snap-fit ​​brackets installed at its upper end, and each U-shaped snap-fit ​​bracket passes through the corresponding through hole and is snapped onto the push frame.

[0014] The lower ends of the two side connecting plates are connected to a base plate, and the base plate is evenly provided with first oil leakage holes. Two side leak-proof plates are symmetrically installed on the side walls of the two side connecting plates, and each side leak-proof plate is connected to the base plate.

[0015] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, each of the side leak-proof plates is provided with a guide plate at its upper end, and each of the guide plates is symmetrically provided with multiple second oil leakage holes, and both ends of each guide plate are connected to the side connecting plate, and the included angle between each guide plate and the side leak-proof plate is 40°-70°.

[0016] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, each of the U-shaped clamping frames includes a connecting vertical frame, and the connecting vertical frame is vertically set on the side connecting plate. A horizontal connecting frame is horizontally set at the upper end of the connecting vertical frame, and an adjusting height frame is vertically set at the end of the horizontal connecting frame away from the connecting vertical frame. The adjusting height frames pass through the corresponding through holes and are clamped on the pushing frame.

[0017] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, each of the above-mentioned adjusting brackets has a contact slot at its lower end, and the contact slot is engaged with the push frame.

[0018] In the above-mentioned vertical oil tank valve slag discharge port anti-splash disassembly device, the sliding sleeve includes a cylinder, and the cylinder is located in the maintenance elongated hole, and the sealing gasket is fixedly connected to the inner side wall of the cylinder. Limiting rings are installed at both ends of the cylinder, and the limiting rings are in contact with the side wall of the anti-splash cover.

[0019] Compared with existing technologies, the beneficial effects of the present invention are as follows:

[0020] 1. The splash guard can be directly placed over the slag discharge port to effectively block splashes that may occur during maintenance, prevent oil from splashing into the surrounding environment, and reduce environmental pollution; after the splashes are blocked by the splash guard, they will not splash onto the maintenance personnel, reducing the risk of injury and protecting the safety of the maintenance personnel.

[0021] 2. The sliding connection of the sliding sleeve within the maintenance elongated hole allows for smoother insertion and movement of maintenance tools, reducing frictional resistance and facilitating precise operations by maintenance personnel. The sliding sleeve within the maintenance elongated hole ensures a tight seal when the maintenance tool enters the slag discharge area, reducing the possibility of oil leakage and thus lowering the risk of personnel contact with oil. The sealing gasket is fixedly connected to the inner wall of the cylindrical sliding sleeve, effectively filling the gap between the maintenance tool and the sliding sleeve to prevent oil leakage from the maintenance elongated hole. The excellent sealing performance ensures that a relatively enclosed space is formed inside the splash guard, better fulfilling its splash-proof function and preventing oil spills from causing harm to the environment and personnel.

[0022] 3. The device's structural design facilitates installation and disassembly. The support drawer is slidably connected to the wedge-shaped groove via wedge-shaped strips, making it easy to pull out for oil cleaning without affecting the continuity of maintenance work. Some oil will flow into the support drawer through the second oil drain hole on the guide plate and the first oil drain hole on the bottom plate, preventing oil from accumulating on the ground or other equipment and further reducing adverse environmental impact.

[0023] 4. The card slot frame and the push frame work together. The height of the card slot frame is adjustable, which can be used for different equipment or applicable scenarios, increasing the versatility and applicability of the device. After maintenance, the card slot frame can be easily removed for rinsing and cleaning, keeping the device clean and in good working condition.

[0024] In summary, the present invention has an ingenious structure that effectively prevents splashing, avoids environmental pollution and personal injury, and the design of the maintenance elongated hole facilitates maintenance operations and ensures sealing; the height of the card slot frame is adjustable, making it highly adaptable, and the carrying drawer is easy to clean of oil stains, thus improving overall maintenance efficiency.

[0038] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0039] Example

[0040] Reference Figure 1-10 A vertical oil tank valve slag discharge port anti-splash disassembly device includes an anti-splash cover 1, which forms a closed space to effectively block the spread of slag discharge port splashes to the surrounding area, preventing environmental pollution and personnel injury. The anti-splash cover 1 has a maintenance elongated hole 7, and a sliding sleeve 6 is slidably connected inside the maintenance elongated hole 7. A sealing gasket 8 is installed between the inner wall of the maintenance elongated hole 7 and the sliding sleeve 6. The sealing gasket 8 is made of high-temperature resistant silicone. For some high-temperature oil tank valve slag discharge port environments, the high-temperature resistant silicone sealing gasket can withstand higher temperatures without losing its sealing performance. It has excellent heat resistance and stability, and can work for a long time at high temperatures while maintaining good flexibility and sealing effect. The sliding sleeve 6 includes a cylinder 602, and the cylinder 602 is located inside the maintenance elongated hole 7. The sealing gasket 8 is fixedly connected to the inner side wall of the cylinder 602. Limiting rings 601 are installed at both ends of the cylinder 602, and the limiting rings 601 are in contact with the side wall of the anti-splash cover 1.

[0041] The splash guard 1 has two symmetrically arranged mounting cavities 10 and two movable slots 4, and each movable slot 4 is connected to the mounting cavity 10 corresponding to its position. Each mounting cavity 10 is slidably connected to a pusher frame 12, and each pusher frame 12 is equipped with a locking mechanism on its side wall. The locking mechanism is located in the movable slot 4 corresponding to its position. The locking mechanism includes a threaded post 9, which is fixedly connected to the side wall of the pusher frame 12. The threaded post 9 passes through the movable slot 4 and is threadedly connected to a locking nut 5.

[0042] The splash shield 1 is slidably connected to a slot frame 3, which is locked onto two push frames 12. The push frames 12 and the slot frame 3 cooperate to fix the splash shield 1. The position can be adjusted according to the actual situation to adapt to different installation requirements. Multiple limit frames 11 are symmetrically installed on the inner side wall of each installation cavity 10. Each limit frame 11 has a limit groove. Multiple limit blocks 14 are symmetrically installed on each push frame 12. Each limit block 14 is slidably connected in the corresponding limit groove. The limit frame 11 cooperates with the limit block 14 on the push frame 12 through the limit groove to restrict the movement direction of the push frame 12, prevent the push frame 12 from deviating, and ensure the stability of the device.

[0043] The splash guard 1 has multiple symmetrically arranged through holes 15, each of which communicates with a corresponding mounting cavity 10. The slot frame 3 includes two symmetrically arranged side connecting plates 304. Each side connecting plate 304 has multiple U-shaped clips installed at its upper end, and each U-shaped clip passes through the corresponding through hole 15 and is clipped onto the push frame 12. The lower ends of the two side connecting plates 304 are connected to a base plate 305, and the base plate 305 has evenly spaced first oil leakage holes 309. Two side leak-proof plates 306 are symmetrically installed on the side walls of the two side connecting plates 304. Each side leak-proof plate 306 is connected to the base plate 305. Each U-shaped clip bracket includes a connecting vertical frame 301, and the connecting vertical frame 301 is vertically set on the side connecting plate 304. A horizontal connecting frame 302 is horizontally set at the upper end of the connecting vertical frame 301. An adjusting height frame 303 is vertically set at the end of the horizontal connecting frame 302 away from the connecting vertical frame 301. The adjusting height frames 303 pass through the corresponding through holes 15 and are locked on the push frame 12. A contact slot 308 is opened at the lower end of each adjusting height frame 303, and the contact slot 308 is locked on the push frame 12.

[0044] Each side leak-proof plate 306 has a guide plate 307 at its upper end. Each guide plate 307 has multiple second oil leakage holes 310 symmetrically opened on it. Both ends of each guide plate 307 are connected to the side connecting plate 304. The included angle between each guide plate 307 and the side leak-proof plate 306 is 40° to 70°.

[0045] A support tray 2 is slidably connected to the inner bottom wall of the splash shield 1. The upper end face of the support tray 2 is provided with a slope 18. The slope 18 on the upper end face of the support tray 2 is designed to allow splashed oil to flow smoothly, making it easy to collect the oil and preventing the oil from flowing randomly inside the splash shield 1. A handle 16 is installed on the side wall of the support tray 2. Multiple wedge strips 17 are symmetrically installed on the lower end face of the support tray 2. Multiple wedge grooves 13 are symmetrically provided on the inner bottom wall of the splash shield 1, and each wedge strip 17 is slidably connected in the corresponding wedge groove 13. The wedge strip 17 and the wedge groove 13 are slidably connected, which facilitates installation and disassembly and makes it easy to clean the collected oil.

[0046] When maintenance is required on the slag discharge port of the oil tank valve, first cover the slag discharge port with the anti-splash cover 1, loosen the locking nut 5, move the locking nut 5 away from the anti-splash cover 1, and move the position of the push frame 12 by the locking nut 5 and the threaded post 9 until it is adjusted to a suitable position and then stop. Tighten the locking nut 5 to firmly fix the push frame 12 and the slot frame 3, so that the slot frame 3 is stably installed at the slag discharge port. The height of the slot frame 3 can be adjusted according to different equipment or applicable scenarios to ensure that the slot frame 3 is locked at the slag discharge port and fits snugly against the slag discharge port.

[0047] A maintenance elongated hole 7 is provided on the anti-splash cover 1. A sliding sleeve 6 is slidably connected inside the maintenance elongated hole 7. The sliding sleeve 6 consists of a cylinder 602 and limiting rings 601 at both ends. A sealing gasket 8 is fixedly connected to the inner wall of the cylinder 602 to ensure the sealing when maintenance tools enter the slag discharge port area through the sliding sleeve 6, preventing oil leakage. During maintenance, if oil splashes, it will be blocked by the anti-splash cover 1. Some oil will flow into the carrying tray 2 through the second oil leakage hole 310 on the guide plate 307 and the first oil leakage hole 309 on the bottom plate 305, avoiding environmental pollution and oil splashes on personnel.

[0048] After maintenance, move the card slot bracket 3 away from the through hole 15 to remove the card slot bracket 3, so that the card slot bracket 3 can be rinsed and cleaned.

[0049] The splash guard 1 has a support tray 2 inside. The upper surface of the support tray 2 is inclined 18, which allows splashed oil and other contaminants to flow into the support tray 2 along the inclined surface. The support tray 2 is slidably connected to the wedge-shaped groove 13 on the inner bottom wall of the splash guard 1 via a wedge-shaped strip 17 on its lower surface, which facilitates installation and disassembly. The oil can be cleaned by pulling the support tray 2 out of the splash guard 1.
