Abstract
The invention discloses an automatic filter with a rotational flow device, belongs to water treatment equipment, and in particular relates to filters for treating circulating water. The automatic filter with the rotational flow device comprises a barrel body, a water inlet, a water outlet, a filter screen and a blowdown pipe and is characterized in that the water inlet and the water outlet are respectively formed in two ends of the horizontal barrel through tapered transitional areas, and the filter screen is installed in the barrel body through a filter screen fixing plate; a water inlet guide plate and a water outlet guide plate which are composed of three uniformly distributed blades are respectively arranged in the tapered transitional areas of the two ends of the barrel body, and the guide plates are fixed on the tapered transitional areas through support frames. The automatic filter with the rotational flow device has the beneficial effects that the filter is provided with the rotational flow device, therefore particle impurities and suspended solids in water are hovered and deposited outside the filter screen of the inner wall of the barrel body under the action of centrifugal force and can be discharged from a discharge outlet along the circumferential tangent line of the barrel wall, the blocking of the stainless steel filter screen is reduced, the filtering efficiency of the filter screen is improved, and the service life of equipment is prolonged.
Description
Technical field
The invention belongs to water treatment facilities, the filter that particularly cycle for the treatment of water uses.
Background technology
In the processing of cycling use of water, conventionally use differential pressure filter and backwash filter, the direct impact filtration net of these filters impure current in service, particle in water and suspension are subject to the pressure of current for a long time, rest in stainless steel filter mesh and produce caulked, block stainless steel screen pack, filter effect declines, and mechanical cleaning difficulty.
Summary of the invention
Exist particle in water and suspension to be subject to for a long time the pressure of current in order to overcome existing differential pressure filter, rest in stainless steel filter mesh and produce caulked, block stainless steel screen pack, filter effect declines, and the deficiency of mechanical cleaning difficulty, the invention provides a kind of automatic filter with swirl-flow devices, should not only can reduce the phenomenon that particle in water and suspension block stainless steel screen pack with the automatic filter of swirl-flow devices.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic filter with swirl-flow devices, comprise cylindrical shell, water inlet, delivery port, screen pack, blow-off pipe, it is characterized in that: the cylindrical shell two ends that level is installed are installed with respectively water inlet and delivery port by conical transition zone, screen pack is arranged in cylindrical shell by screen pack fixed head, the water inlet deflector, the water outlet deflector that are made up of three equally distributed blades are housed respectively in the conical transition zone at cylindrical shell two ends, and described deflector is fixed on conical transition zone by bracing frame.
Described blow-off pipe is arranged in the tangential direction of cylindrical shell excircle, and the blow-off pipe port of export is connecting blowoff valve by flange.
Described water inlet is equipped with respectively with on delivery port sidewall the ball valve that is being connected pressure-measuring pipe, and the pressure-measuring pipe other end is connecting the Pressure gauge and the differential pressure controller that are arranged on electric cabinet, and electric cabinet is connected with the blowoff valve of sewage draining exit.
Described deflector is equipped with eddy flow spreader towards water inlet one side, and spreader axis and tubular axis are same straight line, and the blade on deflector and spreader axis angle are 40-60 degree.
Blade on described deflector and spreader axis angle are 45 degree.
In in the present invention in cylindrical shell, be provided with the deflector with eddy flow spreader facing to the position of water inlet and delivery port center line, shunting effect is more conducive to well form stable eddy flow, has improved the anti-impact force of deflector to current, has extended the service life of equipment.When filter work, water flow rotary flows, and the granule foreign in water and suspension hover and are deposited on outside cylinder inboard wall screen pack under the effect of centrifugal force, have reduced the obstruction of stainless steel filtering net, have improved the filter efficiency of filter.
Filter blow-off pipe is arranged on the tangent to periphery position of cylindrical shell, so after sewage draining exit is opened, first current do tangent to periphery direction eddy flow along cylinder inboard wall and form the circumference fluid under oblique under the effect of deflector, water flow rotary along inwall and is passed downwards in the effect of deflector, the particle and the impurity that suspend are discharged at sewage draining exit along barrel tangent to periphery with current, this structure has shortened blowing time and has reduced water for cleaning and improved the efficiency of blowdown, has reached the object that scrubbing is cleaned automatically.
Owing to being provided with respectively the Pressure gauge that connects differential pressure controller at intake-outlet, when equipment operation, the liquid that contains solid phase impurity enters the internal screen of filter by water inlet, along with the continuation of filter process, solid phase impurity in liquid is trapped within the outer surface of screen pack, when impurities accumulation is when a certain amount of, causes that screen pack both sides pressure reduction increases, filtration resistance increases, and filter efficiency declines.In the time that the pressure differential of screen pack both sides reaches setting value, differential pressure controller provides signal to switch board, and switch board sends command adapted thereto, and blowdown motor-driven valve is opened automatically, and dirt is discharged system from sewage draining exit.After blowdown a period of time, motor-driven valve valve-closing.In the time that the pressure differential of filter element both sides reaches again setting value, repeat above operation, can realize filter process automation.
The invention has the beneficial effects as follows that filter installed swirl-flow devices and made granule foreign and suspension in water hover and be deposited on outside cylinder inboard wall screen pack under the effect of centrifugal force, when granule foreign deposits to after certain volume, can set and realize Automatic Control by pressure reduction and time, also can carry out blowdown by manual control, granule foreign also can be discharged at sewage draining exit along barrel tangent to periphery, reduce the obstruction of stainless steel filtering net, improve the filter efficiency of filter, extend the service life of equipment, reduced the operation and maintenance cost of equipment.
