Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0012] As shown in the figure, an anti-clogging spray filter for self-elevating platform includes high-pressure water device 1, compressed air device 2, upper end cover 3, water inlet 4, filter 5, submersible lift pump 6, sewage discharge System 7, lower end cover 8 and water outlet 9. The upper end cover 3 of the filter 5 is connected with the high-pressure water device 1 and the compressed air device 2 through the valve pipeline, the lower end cover 8 of the filter 5 is connected with the sewage system 7 through the valve pipeline, and the water inlet 4 of the filter 5 is connected with the submersible lifting The pumps 6 are connected, and the water outlet 9 of the filter 5 is connected to the platform water supply system.
[0013] The water inlet 4 and the water outlet 9 are located in the middle of the main body of the filter 5. The main body of t...

The invention discloses an anti-blocking purging filter used for self-elevating platform and belongs to the technical field of ocean engineering. The anti-blocking purging filter comprises a high pressure water device, a compressed air device, an upper end cover, a water inlet, a filter, a submersible lift pump, a drainage system, a lower end cover and a water outlet, wherein the upper end cover of the filter is connected with the high pressure water device and the compressed air device through valves and pipes, the lower end cover of the filter is connected with the drainage system through valves and pipes, the water inlet of the filter is connected with the submersible lift pump, and the water outlet of the filter is connected with a platform water supply system. The water inlet and the water outlet are positioned at the middle of a main body of the filter, the main body of the filter is a hollow cylinder, and a filtering element is arranged in the hollow cylinder. A valve opening is formed on the lower end cover and connected with the drainage system, and the diameter of the valve opening is half of that of the main body of the filter. In case of blocking, the filter is directly and automatically cleaned and dredged through the high pressure water device and the compressed air device without needing to dismount, which is convenient and practical.
Description
technical field [0001] The invention relates to an anti-clogging jetting filter, mainly an anti-clogging jetting filter used for a self-elevating platform, and belongs to the technical field of marine engineering. Background technique [0002] At present, during the production and operation of offshore jack-up platforms, they often encounter harsh sea conditions, and seawater turbidity occurs, which has a great impact on the seawater lifting system of the platform, and the filter is often blocked. However, it is very difficult to dismantle and repair the filter, which not only affects production and life, but also brings major safety hazards to platform firefighting. Once a fire occurs, the supply of firefighting water will not be guaranteed, which is an urgent problem to be solved. Contents of the invention [0003] It is an object of the present invention to provide an anti-clogging spray filter for jack-up platforms. [0004] The problem to be solved by the present in...
