High-corrosion resistance aluminum alloy filter and process thereof

Abstract

The invention relates to a high-corrosion resistance aluminum alloy filter and a process thereof. The filter is used for seawater desalination in environments like a ship and an offshore drilling platform. The high-corrosion resistance aluminum alloy filter comprises a shell composed by a barrel and a top cover, wherein the top cover is an aluminum-magnesium-silicon alloy cast part and at least comprises an upper liquid inlet branch pipe, a round head and bolt pressing plates uniformly distributed around the round head, the barrel is a series-5 aluminum-magnesium alloy barrel, a barrel flange is arranged at an interconnecting part of the barrel and the top cover, the barrel flange is a low pressure precision cast part and is provided with a lower liquid inlet branch pipe, the circumference of the flange is provided with bolt fixing plates arranged relative to the bolt pressing plates, an O-shaped ring recess is arranged on a contact surface of the barrel flange and the top cover, the lower liquid inlet branch pipe is in butt joint with the upper liquid inlet branch pipe, the bolt pressing plates are in fixed connection with the bolt fixing plates. The invention also relates to a process for the high-corrosion resistance aluminum alloy filter. According to the invention, the filter provided by the invention can be used in a seawater corrosion environment, and production efficiency is improved by 2 to 3 times.

Description

technical field [0001] The invention relates to a filter, especially a high-corrosion-resistant aluminum alloy filter and its technology, which are used in seawater desalination treatment, ships, offshore drilling platforms and other environments. technical background [0002] In the water desalination filtration method, such as the membrane method, the filter is an indispensable unit. The traditional conventional filter has such factors as corrosion resistance, small flow rate, inconvenient replacement of the filter element, and high cost, which are difficult to meet the requirements of modern engineering. demand. The most important technical problem is the housing material of the filter. At present, carbon steel and austenitic stainless steel materials for containers are widely used as filter housing materials. Poor, the above-mentioned two kinds of materials are mainly used in filters such as seawater desalination, ships and offshore drilling platforms are obviously lim...
