Description
Technical field
What the bypass filtration device of band backwash of the present invention related to is a kind of shunting sedimeter that has backwashing function.Be applicable to liquid filtering field, particularly water, wet goods liquid filtering.
Background technology
The main key technology of liquid filtering is the impurity discharging, design of main at present employing shunting or backwash design, adopt shunting along flushing and two kinds of technical schemes of backwash, realize automation easily along flushing, but wash not thorough, impurity embeds to form in the filter mesh and stops up, and backwash needs a plurality of valve controls, and fault rate is higher.
Summary of the invention
The present invention seeks to provides a kind of bypass filtration device with backwash at above-mentioned sufficient again part, and the impurity in the liquid is filtered, and will combine along flushing and recoil dual mode, and flushing liquid filters the impurity that produces.The bypass filtration apparatus structure of band backwash is simple, easy to operate, easier realization automation control, and impurity is rinsed well thoroughly, can not cause filter mesh to stop up, and can improve the filter filter effect.
The bypass filtration device of band backwash takes following scheme to realize: the bypass filtration device of band backwash comprises control valve, filter flask, filter core and blowoff valve; Control valve is contained in filter flask top, and filter core is housed in the filter flask, and blowoff valve is equipped with in the filter flask bottom.
Control valve has valve body, is provided with piston cylinder in valve body, is provided with inlet, liquid outlet in valve body one side, valve body top is provided with valve head, and the valve head inner chamber is equipped with swivel nut, and screw rod is housed in the swivel nut, piston is equipped with in the screw rod bottom, and piston is contained in the piston cylinder, can take action up and down along the piston cylinder inwall.The valve head inner chamber is provided with the swivel nut positioning boss, and the swivel nut periphery is provided with locating slot, matches with the swivel nut positioning boss, and piston can only upper and lowerly be taken action, and can not rotate.Knob or stepper motor are equipped with in the screw rod top, can manually control or control automatically.Stepper motor adopts commercially available stepper motor.
Filter core is equipped with in the piston cylinder bottom, between piston cylinder and the filter core seal washer is housed, and piston cylinder one side is connected with inlet, and piston cylinder top one side is jagged to be connected with liquid outlet.
Filter core comprises filter screen bracket, filter core lid, filter membrane or screen pack, and filter membrane or screen pack are housed in the filter screen bracket, and the filter core lid is equipped with at the filter screen bracket two ends.Filter membrane adopts commercially available hollow-fibre membrane or planar film.As adopt screen pack, and in the screen pack filtrate or medicament can be housed, filtrate can adopt commercially available filtrate KFD, active carbon, wheat aluminite and mineralization ball etc., and medicament adopts commercially available disinfectant, antisludging agent etc.
Bottom, filter screen bracket bottom is contained in the filter flask bottom by the filter core lid, and adopts the sealing ring sealing, and the filter screen bracket bottom communicates with blowoff valve, and blowoff valve adopts commercially available stop valve, magnetic valve etc.Operation principle:
During operate as normal, piston is at the top of piston cylinder, liquid enters in the filter core by inlet and piston cylinder, flow into filter flask from the filter core side by filtrate, medicament, screen pack or hollow-fibre membrane, transfer out by liquid outlet again, being filtered impurity is retained in the filter core, open blowoff valve, impurity is flushed away (during suitable the flushing), filter flask bottom also can with the less demanding utensil of impurity is connected, when this utensil uses, can realize the discharging of impurity by blowoff valve, for example link to each other with water closet, can make full use of water resource, reach the water saving purpose.
When the needs backwash, rotary screw or drive piston by stepper motor, make descent of piston to piston cylinder bottom with the capping of filter core top, liquid enters the liquid outlet of valve body by the breach of liquid-inlet and piston cylinder top one side at this moment, enters filter flask again, enter in the filter core by filter screen or filter membrane outside, open blowoff valve, the impurity trapped in the filter core is recoiled from the blowoff valve discharging, promptly realize backwash.Stepper motor can be controlled automatically by Programmable Logic Controller.
The bypass filtration device of band backwash is reasonable in design, simple for structure, the reliability height filters the impurity in the liquid, and impurity screening is washed, to combine along flushing and backwash dual mode, the impurity flushing is more thorough, can not cause filter mesh to stop up, and is easy to realize automatic control, impurity in the liquid is carried out the filter efficiency height, the operational reliability height.
