a filter

Abstract

The invention discloses a filter which comprises a cover body (1) and a cylinder body (2), and further comprises a filter screen (4) rotatably arranged in the cylinder body (2), and a scraping bar (3) in contact with the outer wall of the filter screen (4). The filter is provided with the scraping bar and the rotatable filter screen, the scraping power of the scraping bar is used for fully clearing attachments on the filter screen. The cleaning process is finished without dismantling the filter, the whole process is simple and convenient, and the risk of water leakage caused by dismantling the filter is eliminated.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a filter. Background technique [0002] The filter is usually installed behind the water meter of the water inlet pipe to filter the sediment and impurities generated in the pipe network, reduce the secondary pollution generated in the pipe network, avoid the damage caused by the sediment to the human body, and cause damage to hidden pipes, faucets, electrical appliances, etc. Active protection, is a reliable impurity filter. [0003] Such as figure 1 As shown, the filter screen in the filter is fixed on the filter screen support, the filter screen support is a cylindrical structure surrounded by grids, and the filter screen is wrapped on its outer wall, which is also arranged in a cylindrical shape. When the filter is working normally, the water flow enters from the water inlet on the top of the filter, and there is a partition between the water inlet and the water outlet, which...

Problems solved by technology

[0005] If it is used for a long time, more sediment will be produced, which will reduce the water output of the filter and no water will come out. It is difficult to wash the attachments from the filter with conventional flushing methods. At this time, the filter must be disassembled and cleaned.

Since the filter is easy to attach and precipitate, it needs to be disassembled frequently by the user. The operation process is very inconvenient, and there is a risk of water leakage during the disassembly process.
