Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of water filters, in particular to a self-cleaning water filter.
[ background of the invention ]
The filter screens of the pre-filters are all sintered filter screens, and because the filter screens are long-term used elements, impurity flushing on the filter screens is a very important technical barrier in the process of filtering impurities in a pipeline. At present, most manufacturers adopt two flushing modes: the first is a positive washing mode, namely the direction and the flow of the product filtration are the same; the second is a reverse direction flush, which flushes from both the inside and outside of the screen.
Adopt above-mentioned two kinds of modes to wash impurity along the direction of former filtration water route, such washing mode has following drawback: the washing direction is the same as the filtering direction, and the washing efficiency is not high and is not thorough. The reason is as follows: because water route protector's filtration mode is through the interception of filter screen and separates the granule impurity in the running water, consequently most granule impurity all attaches to on the filter screen, when washing the direction the same with the filtration direction, these granule impurity on the filter screen receive the space protection of filter screen, can't openly wash, so wash unclean.
The invention is provided for overcoming the defects of the prior art.
[ summary of the invention ]

The invention can be realized by the following technical scheme:
the invention discloses a self-cleaning water filter, which comprises a shell, wherein an upper cover is in threaded connection with the upper part of the shell, an outer filter screen in threaded connection with the upper cover is fixed below the upper cover, an inner filter screen is also fixed inside the outer filter screen, filter holes are uniformly formed in the inner filter screen and the outer filter screen, a gap is formed between the inner filter screen and the outer filter screen, a water inlet penetrating through the upper cover is formed in the upper cover at the position of the inner filter screen, a water inlet pipe connected with a tap water pipe is fixed on the upper cover at the position of the water inlet, a valve I is fixed on the water inlet pipe, the water inlet pipe is also connected with the upper cover through a flushing pipe, the bottom of the flushing pipe is arranged in the gap between the inner filter screen and the outer filter screen, a valve II is fixed on the flushing pipe, and a water outlet pipe connected with the inner part of the shell, and a valve III is arranged on the water outlet pipe, a drain pipe is further fixed at the bottom of the shell, and a valve IV is fixed on the drain pipe. When the filter is used, the valve I and the valve III are opened, the valve II and the valve IV are closed, tap water of a tap water pipe enters the inner filter screen through the water inlet pipe, the tap water is filtered by the inner filter screen and then passes through the outer filter screen and then is discharged through the water outlet pipe for use, particle impurities in the tap water are remained on the inner wall of the inner filter screen, after the filter is used for a period of time, the valve I and the valve III are closed, the valve II and the valve IV are opened, the tap water enters a gap position between the outer filter screen and the inner filter screen through the flushing pipe, the tap water in the shell can not be discharged through the water outlet pipe and can only be discharged through the drain pipe, and the tap water is required to enter the inner filter screen through the filter holes in the inner filter screen from the gap position and then is discharged through the drain pipe after entering the gap position between the outer filter screen, when the running water passes through the filter holes in the inner filter screen, the running water washes the attached particle impurities on the inner wall of the inner filter screen, the particle impurities are discharged through the blow-off pipe after being separated from the inner filter screen, the self-cleaning of the filter screen of the filter can be effectively realized, after the impurities are discharged, the valve I and the valve III are closed, the valve II and the valve IV are opened, the service life of the filter can be effectively prolonged, the outer filter screen and the inner filter screen are cleaned after the outer filter screen is taken down from the upper cover through separating the upper cover from the shell, and the service life of the filter is further prolonged.
Preferably, a thread block is fixed below the upper cover, an external thread in threaded connection with the inner wall of the shell is arranged on the outer wall of the thread block, and an internal thread in threaded connection with the outer wall of the outer filter screen is arranged on the inner wall of the thread block.
Preferably, the bottom of the outer filter screen is fixed with a positioning pipe, and the positioning pipe is in interference fit with the sewage discharge pipe. Can effectively prevent particle impurities from reaching the position of the water outlet pipe between the positioning pipe and the sewage discharge pipe.
Compared with the prior art, the invention has the following advantages:
1. inside the interior filter screen was entered into from the clearance position between interior filter screen and the outer filter screen to the running water, when the running water passed through the filtration pore on the interior filter screen, the running water washed the adnexed granule impurity of interior filter screen inner wall, and granule impurity discharges through the blow off pipe after with interior filter screen separation, can effectively realize the self-cleaning of filter screen, can effectively prolong the life of filter.
2. Through separating upper cover and shell, take off the back with outer filter screen from the upper cover and wash outer filter screen and interior filter screen, further extension filter's life.
