Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas production, in particular to a filter screen cleaning device for offshore oil platform pumps. Background Art

[0002] When the fluid flows through the pump body, it must first pass through the pump pre-filter to intercept and filter the impurities and suspended matter in the fluid, and then enter the pump chamber to be pressurized and output under the action of the centrifugal force of the high-speed rotation of the impeller. The pre-filter can prevent impurities from damaging the mechanical mechanism of the pump impeller, and at the same time protect the downstream equipment from impurity accumulation and blockage. Therefore, the cleaning of the filter in the pump pre-filter is a daily basic maintenance work of the offshore platform, which is of great significance to ensure the efficient, stable and continuous operation of the pump.

[0003] At present, the cleaning of offshore platform filters relies on brushes and flushing water, without special equipment. When cleaning, you need to find an unfixed place first, and then use a hose connected to a pressurized water source to connect the flushing gun head to flush the dirt and impurities on the inner and outer walls of the filter. This conventional method has low cleaning efficiency, and when cleaning a larger filter, two people are required to cooperate in the operation, which consumes manpower. When the flushing water pressure is high, the filter is easy to roll over and injure people. At the same time, there are also problems such as poor cleaning effect and easy pollution of the surrounding environment. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be clearly and completely described below through specific implementation methods.

[0022] like Figure 1-4As shown, the utility model is a pump filter cleaning device designed with a rectangular box structure, and an auxiliary structure is arranged in the box 1, the auxiliary structure includes a height-adjustable grille plate 2 (the grille plate 2 is connected to the support leg 8 by bolts and nuts, and the height of the grille plate 2 is adjusted by the depth of the bolts screwed into the nuts), the function of which is to keep the filter screen always above the dirty oil water and sludge impurities to prevent the washed filter screen from contacting with its dirt; the auxiliary structure also includes a detachable ring structure with double rods and a detachable disc structure with a single rod, the ring structure with double rods is convenient for the box 1 The filter is fixed in the forward direction (the basket filter opening is upward) inside to prevent tipping and movement, and is convenient for washing dirt and impurities on the inner wall. The disc-shaped structure with a single rod is convenient for hanging and fixing the filter in the reverse direction (the basket filter opening is downward) inside the box 1, which is convenient for washing dirt and impurities on the outer wall and making all the dirt and impurities on the bottom of the filter and the inner and outer walls fall into the box 1 under the action of gravity; a hinged movable door with a sealing rubber strip is set on the side of the box 1 to facilitate personnel to enter the box 1 to clean the dirty oil sludge impurities accumulated inside; a sewage discharge port with a valve is set at the bottom of the box 1 to control the discharge of dirty oil water for cleaning the filter. The filter cleaning device of this application can effectively prevent the splashing of dirty oil and water caused by cleaning the filter from polluting the environment, making the filter cleaning work more convenient and efficient.

[0023] Specifically, a pump filter cleaning device includes a box body 1, a grille plate 2, a sleeve double-rod annular support structure 3, a sleeve single-rod disc support structure 4, a sleeve rod 5, a hinged side door 6, a valve 7, and a support leg 8.
