Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of water filters, in particular to a backflushing type 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 object of the present invention is to overcome the above-mentioned drawbacks of the prior art and to provide a backflush water filter which allows an effective cleaning of the filter screen.
The invention can be realized by the following technical scheme:
the invention discloses a backflushing water filter, which comprises a shell, wherein a water inlet pipe connected with a tap water pipe is fixed on the upper end surface of the shell, a drain pipe is fixed on one side of the bottom of the shell, a valve is fixed on the drain pipe, an installation groove is arranged at the bottom of the shell, a filtering device is fixed in the installation groove, the filtering device comprises a sealing cover assembled with the installation groove, a water outlet pipe is fixed at the bottom of the sealing cover, a filter screen is also fixed on the sealing cover in the shell, a backflushing device is fixed in the filter screen, the backflushing device comprises a supporting plate and a connecting plate which are arranged on two sides in the filter screen, a supporting shaft is fixed at the top of the supporting plate, the supporting shaft is connected with the filter screen through a bearing, a water guide plate is also fixed between the supporting plate and the connecting plate, the cross section of the water guide plate is spiral, the water guide plate is characterized in that a water outlet penetrating through the connecting plate is formed in the connecting plate in the middle of the water guide plate, a connecting pipe is further fixed at the position of the water outlet on the lower end face of the connecting plate, the connecting pipe is sleeved with a water outlet pipe through a bearing, and a baffle is further vertically fixed on one side of the outer end face of the water guide plate. When the filter is used, tap water enters the shell through the water inlet pipe, passes through the filter screen and is discharged through the water outlet pipe for use, the connecting pipe is sleeved in the water outlet pipe, the water guide plate is fixed above the connecting plate, the supporting plate is fixed on the upper end surface of the water guide plate, the filtered water can reach the position of the water outlet pipe only through the water guide plate, the cross section of the water guide plate is spiral, the filtered water enters the inside of the water guide plate through the water inlet on the water guide plate, namely the track of the filtered water entering the innermost side of the water guide plate is spiral, the water collides with the water guide plate in the process of entering the most central position of the water guide plate, the water guide plate automatically rotates in the filter screen, the baffle fixed outside of the water guide plate rotates along with the water guide plate, and when the baffle rotates, the baffle pushes the water in the filter screen to reach the outside through the filter screen through the filter holes, promote water through the baffle and remove automatic erodeing the filter screen, avoid being attached to on the filter screen outer wall have particle impurity, a period of time back, particle impurity subsides the bottom in the shell, through opening valve on the blow off pipe, particle impurity passes through the blow off pipe and discharges, realizes water guide plate autogyration through the water guide plate structure to the baffle promotes the inside water of filter screen along with the water guide plate is washd back to the filter screen, can effectively avoid impurity to be attached to on the filter screen outer wall.
Preferably, a thread block is further fixed on the housing at the installation groove, and the sealing cover is in threaded connection with the thread block.
Compared with the prior art, the invention has the following advantages:
the water guide plate self-rotation is realized through the water guide plate structure, the baffle pushes the water inside the filter screen to perform backwashing on the filter screen along with the rotation of the water guide plate, and impurities can be effectively prevented from being attached to the outer wall of the filter screen.
