Description

Technical Field

[0001] The invention relates to the technical field of petrochemical industry, in particular to a splash-proof disassembly device for a slag discharge port of a vertical oil tank valve. Background Art

[0002] In the petrochemical industry and other industries, the valve slag outlet and filter of the vertical oil tank need to be regularly deslagging and cleaned in daily work. If the slag is not discharged in time, some hard impurities may damage the sealing surface of the valve, causing the valve to be unable to close tightly and causing internal seepage. Excessive impurities will also cause the pipeline flow to decrease, the flow rate to increase, and the static electricity to increase. During the maintenance process, when disassembling the plug and blind plate, splashing often occurs when the plug or blind plate is about to be removed, which not only causes environmental pollution, but also may cause oil stains to splash on personnel.

[0003] At present, in order to solve the problem of splashing at the slag outlet, some methods are to add a small valve to the slag outlet, but this also increases the leakage point, increasing the difficulty and danger of daily management. Moreover, the existing protective measures often cannot effectively collect splashing, and are difficult to adapt to different equipment and work scenarios. In addition, there is a lack of effective solutions for the sealing problem during maintenance. When the maintenance tools are inserted into the slag outlet area, oil leakage is likely to occur, further increasing environmental pollution and safety risks.

[0004] To this end, we propose a vertical oil tank valve slag outlet anti-splashing disassembly device to solve the above problems. Summary of the invention

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

[0015] In the above-mentioned vertical oil tank valve discharge port anti-splashing disassembly device, a material guide plate is provided at the upper end of each side anti-leakage plate, and a plurality of second oil leakage holes are symmetrically opened on each material guide plate, and both ends of each material guide plate are connected to the side connecting plate, and the angle between each material guide plate and the side anti-leakage plate is 40°-70°.

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

[0021] 2. The sliding connection of the sliding sleeve in the long maintenance hole makes the maintenance tool smoother during insertion and movement, reduces friction resistance, and is convenient for maintenance personnel to perform delicate operations. The sliding sleeve in the long maintenance hole ensures the sealing of the maintenance tool when entering the slag outlet area, reduces the possibility of oil leakage, and thus reduces the risk of personnel contacting oil. The sealing gasket is fixedly connected to the inner wall of the cylinder of the sliding sleeve, which can effectively fill the gap between the maintenance tool and the sliding sleeve to prevent oil leakage from the long maintenance hole. Good sealing performance can ensure that a relatively closed space is formed inside the anti-splash cover, better play the role of anti-splash, and avoid oil spills from causing harm to the environment and personnel.

[0022] 3. The structural design of the device is easy to install and disassemble. The load-bearing drawer is connected to the wedge-shaped slide slot by sliding, which is convenient for pulling out to clean the oil, without affecting the continuity of maintenance work. Part of the oil will flow into the load-bearing drawer through the second oil leakage hole on the guide plate and the first oil leakage hole on the bottom plate, avoiding the accumulation of oil on the ground or other equipment, further reducing the adverse impact on the environment.

[0023] 4. The card slot frame and the push frame are used together. The height of the card slot frame is adjustable and can be applied to different equipment or scenarios, which increases the versatility and applicability of the device. After maintenance, the card slot frame can be easily removed for flushing and cleaning to keep the device clean and in good working condition.

[0024] In summary, the present invention has an ingenious structure, can effectively prevent splashing, avoid environmental pollution and personal injury, and designs such as long maintenance holes facilitate maintenance operations and ensure sealing; the card slot frame is height-adjustable and has strong applicability, and the load drawer is convenient for cleaning oil stains, thereby improving overall maintenance efficiency.
