Description

Technical Field

[0001] This utility model relates to the field of oil storage tank drainage technology, and in particular to an oil storage tank drainage device. Background Technology

[0002] As a key facility in the oil extraction, transportation, storage, and refining process, oil storage tanks undertake the long-term storage of crude oil, refined oil products, and various petrochemical products. During the use of oil storage tanks, water accumulation is unavoidable. This water mainly comes from two aspects: first, external environmental factors, such as rainwater seeping in through gaps in the tank's breather valve, manhole, etc., or condensation formed by water vapor in the air on the inner wall of the tank; second, the moisture carried by the petroleum products themselves, especially crude oil, which inevitably mixes with a certain amount of free water during extraction and transportation. Therefore, if water accumulates inside the storage tank, it is necessary to drain the oil storage tank.

[0003] Modern oil tank drainage devices can basically meet people's needs, but there are still some problems, as follows: When the device is in use, it needs to be connected to the oil tank. The connection between the device and the oil tank needs to be simple and quick to prevent the device from falling off. Utility Model Content

[0004] The purpose of this invention is to provide a drainage device for oil storage tanks, which solves the problem that existing drainage devices for oil storage tanks are difficult to connect to oil storage tanks.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drainage device for an oil storage tank, including a base; A base plate is installed at the top of the base, a telescopic structure is installed at the top of the base plate, a housing is installed at the top of the telescopic structure, and a water pump is installed inside the housing. A water outlet pipe is installed on one side of the shell, a conduit is installed on the other side of the shell, a connecting structure is installed on one side of the conduit, and a connecting pipe is installed on one side of the connecting structure. The connection structure includes a second flange installed on one side of the conduit, and a first flange installed on one side of the second flange, with a positioning block installed inside the second flange.

[0006] In use, the first flange and the second flange are first engaged to connect the conduit to the connecting pipe on the oil storage tank. After connecting the conduit to the connecting pipe on the oil storage tank, the water pump works to generate suction, which draws out the water inside the oil storage tank and sends it through the conduit to the outlet pipe, and then the water is discharged through the outlet pipe.

[0007] Furthermore, the telescopic structure includes a second telescopic rod installed at the top of the base plate, a first telescopic rod installed at the top of the second telescopic rod, a connecting rod installed inside the first and second telescopic rods, and a positioning screw installed at one end of the second telescopic rod. The telescopic structure can adjust the height of the device.

[0008] Furthermore, the second telescopic rod has a sliding groove inside, and the bottom end of the first telescopic rod has a slider. The second telescopic rod and the first telescopic rod form a sliding structure, and the first telescopic rod can slide inside the second telescopic rod.

[0009] Furthermore, the positioning screw and the second telescopic rod form a threaded connection, and the positioning screw is symmetrically distributed about the central axis of the connecting rod, so that the positioning screw can fix the first telescopic rod.

[0010] Furthermore, a valve structure is installed on one side of the conduit. The valve structure includes a valve body installed on one side of the conduit, a rotating shaft installed inside the valve body, valve plates installed on both sides of the rotating shaft, and a handle installed at the top of the rotating shaft. The valve structure can seal the conduit.

[0011] Furthermore, a connecting block is installed at the top of the positioning block, a filter screen is installed on the inner side of the connecting block, a fixing screw passes through one side of the first flange, and a nut is installed on one side of the fixing screw. The filter screen can filter the water entering the conduit.

[0012] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the nut are threadedly connected, and the fixing screw and the nut can connect the first flange and the second flange together.

[0013] The advantages of the oil storage tank drainage device provided by this utility model are: the device can be connected to the outlet pipe of the oil storage tank through the connecting structure; the height of the device can be adjusted through the telescopic structure, so that the device can drain oil storage tanks of different heights; and the opening and closing of the conduit can be controlled through the valve structure.

[0014] By installing a second flange on one side of the conduit, the second flange and the first flange form a snap-fit ​​structure. The first flange and the second flange fit together to connect the conduit to the connecting pipe on the oil storage tank. The fixing screws and nuts form a threaded connection, which can be used to fix the first flange and the second flange together, ensuring stability. At the same time, the filter screen inside the second flange can filter the passing water to prevent impurities from entering the conduit. The connecting block and positioning block on the outside of the filter screen form a snap-fit ​​structure, which facilitates the removal and replacement of the filter screen when the flange is disassembled. This achieves the purpose of facilitating the connection of the oil storage tank drainage device to the oil storage tank.

[0015] A valve body is installed on the outside of the conduit. The handle at the top of the valve body can be rotated. By grasping the handle and rotating it, the shaft can be rotated, which in turn rotates the valve plate. The rotation of the valve plate can control the opening and closing of the conduit. When the valve plate is parallel to the valve body, the conduit can be opened. When the valve plate is perpendicular to the valve body, the conduit can be closed. This achieves the purpose of making it easy to control the opening and closing of the conduit in the oil storage tank drainage device. Attached Figure Description
