Abstract
The utility model is provided with a screen filter used in the farmland water-saving irrigation system in particular to a horizontal automatic backwashing screen filter basically includes a shell, a water inlet pipe, a water outlet pipe, a sewage discharge pipe and a filter cartridge with the property of backwashing which is arranged inside the shell. A ring platform is arranged at one end of the shell, and a flange and a block plate matched with the ring platform is arranged outside the shell. A water outlet is arranged on the shell; a filter cartridge is arranged inside the shell; whirl vanes are arranged on the end of the filter cartridge close to the water inlet pipe; a three-way is arranged on the other end of the shell. Double frame (inner and outer) nip-net type backwashing filter cartridge is adopted for the utility model, which can reduce the damage to the filter screen during backwashing and improve the lifetime of the filter screen. Then, the whirl vanes can make the water which flows into the filter cartridge circumrotate to reduce the impurity attaching to the filter screen, to be beneficial for the backwashing, to improve the stability of work and to reduce the happening of malfunction; during the process for removing the impurity, the work of the water pump is not needed to stop; the leading electromagnetic valve close to the water inlet and the sewage discharger mouth which is adopted to control the implementation of the backwashing, can realize uninterrupted irrigation, and is time-saving and effort-saving and improves the work efficiency; the anti-corrosion material is adopted for the whole filter shell, therefore, the filter shell has certain performance of anti-corrosion.
Description
Technical field
The utility model belongs to the granular membrane used in the farmland water-saving irrigation system, relates in particular to a kind of horizontal automatic backwash granular membrane.
Background technology
At present; the granular membrane of using in the farmland water-saving irrigation system is installed in the rearmost end of multistage filtering system more; for afterbody filters; basic structure mainly comprises housing; water inlet pipe; outlet pipe and the individual layer skeleton is arranged and filter cylinder that filter screen constitutes; its effect is extremely important; its main effect is in order to remove the insoluble substance in the water; assurance enters spray; the water that drip irrigation is irrigate system is clean water; but the water quality of farmland irrigation water is bad now; insoluble tangible impurity is more, and swirl vane is not installed at the water inlet pipe place, and impurity easily adheres to; all kinds of impurity often can accumulate on the filter screen; in the course of time, the water that can enter filter screen just reduces gradually, and the hydraulic pressure that acts on simultaneously on the filter screen constantly increases; if untimely filter screen is taken out manually cleaned; filter screen will deform, and filter screen also can be squeezed by hydraulic pressure and break when serious, if impurity enters in the pipeline; will cause great destruction to whole water-saving irrigation system, bring enormous economic loss.Individual layer skeleton cartridge structure destroys filter screen easily during backwash, generally not backwash, and necessary termination of pumping is regularly cleaned filter screen, not only increases the weight of workload, and often cleans filter screen, can make the filter screen serious wear, causes the certain economic loss.Conventional screen web filter housing adopts iron and steel to process, and easily gets rusty, and antiseptic property is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of and is beneficial to that backwash, working stability, fault rate are low, the horizontal automatic backwash granular membrane of long service life.
The utility model is a kind of granular membrane that utilizes anti-corrosion material to process to have the automatic backwash function, it comprises water inlet pipe, outlet pipe, blow-off pipe, housing and is installed in the interior filter cylinder that possesses the backwash characteristic of housing, it is characterized in that: an end outer wall of housing is provided with the ring platform, housing is provided with outward and encircles flange and the baffle plate that platform matches, on housing, be provided with delivery port near ring platform one end, also can change the delivery port that is made as filter with increasing interface, the other end of housing is provided with threeway, and its threeway also can link to each other with housing by reducing joint.Two other outlet of threeway has a reducing joint and a flange respectively, reducing joint and flange are connected to magnetic valve respectively again, magnetic valve is controlled by circuit, the water route is flowed to implementation control, thereby finish the automatic backwash function, be provided with the filter cylinder that possesses the backwash characteristic in the housing, filter cylinder adopts inside and outside two skeletons folder net formula backwash filter cylinders.That end of filter cylinder near threeway in housing is provided with swirl vane, and the current that enter in the net are rotated, and prevents that impurity is attached to above the net, help backwash, improve the service life of filter cylinder, thereby reach working stability, the good filter effect that fault rate is low.
Because of filter cylinder of the present utility model adopts inside and outside two skeleton folder net formula backwash filter cylinder, can not damage during backwash filter screen, improve the service life of filter cylinder, so help backwash.The utility model is a Combination Design, is beneficial to assembling, can be widely used in the filtration of farmland water-saving irrigation system.
