The purpose of this utility model is to solve that existing discal filter filter element backwash effect is poor, complex structure and duty can't guarantee, and then provide a kind of safe and reliable to operation, backwash effect is obvious, and wrinkle disk piece filter simple in structure.
Its basic system of the utility model comprises housing, gland, water inlet, delivery port, blow-off pipe and base, the two ends that it is characterized in that housing are connected with delivery port with gland respectively, its water inlet and blow-off pipe are positioned on the outer wall of housing, and water inlet and blow-off pipe all with in the housing communicate, and base is positioned at the bottom of housing, be provided with filter core in the housing, backwash control device and center framework, the upper end of filter core is provided with the backwash control device, its backwash control device is successively by spring, guide post and last pressure slide block are formed, the filter core lower end links to each other with base, base is fixed in the end in the housing, its filter core integral body is socketed in the outside of center framework, center framework is to be fixed in central circular by many to become the support bar combination of circumferential arrangement to form, the bottom of center framework is fixed in the base, an all nested center pull rod in the every support bar in center framework upper end, center pull rod one end is connected presses on the slide block, last pressure slide block center is connected on the guide post, one end of guide post is fixed on the gland, gland and last the pressure between the slide block are provided with spring, and its spring housing is connected on the outside of guide post.
Center pull rod and backwash control device have been set up in the utility model inside; its backwash control device is successively by spring; guide post and the last slide block of pressing are formed; center pull rod one end is fixed on presses slide block; its center pull rod self is nested in the support bar; can stretch freely; it is too many to guarantee that the filter screen of wrinkle in backwash or disc can not depart from center framework; play spacing effect; guarantee to get back to smoothly on the support bar after backwash is finished, protected the filter screen or the disc of wrinkle, improved the service life of the filter screen or the disc of wrinkle; cost when having reduced the filtration system operation; overall structure is simple, and backwash process is simple, and effect is obvious.
