Summary of the invention
For above many disadvantages, the present invention proposes the technical scheme that solves in-problem key element:
Flexible tube presser comprises that mainly filter assemblies, compression system, filter residue are discharged system, filtrate is discharged system, pipe-line system, filter residue induction system and control system, and comprehensively becomes the full-automatic Separation of Solid and Liquid integrated treatment of electromechanical integration complete set of equipments; Filter residue is discharged system's involving vibrations and mechanical deslagging assembly; Filter assemblies comprises a folded filter element; One folded filter element is arranged in parallel on the rack rail that is arranged on frame and can relatively moves along arranging fore-and-aft direction, and arranging fore-and-aft direction is also the squeeze force direction of compression system; Compression system is that the short transverse at filter assemblies arranges at least a cover and compresses assembly, and compressing assembly is to comprise pressing structure, rack rail, frame and thrust generating mechanism; Pressing structure comprises pressing plate and bearing plate assembly; This filter element comprises that position limiting structure before and after upper flange, screen pipe unit, filter chamber, filter chamber left and right position-limit mechanism, horizontal filtrate collects dish and mechanical deslagging assembly; Upper flange comprises hermetically-sealed construction and walking mechanism on filter chamber, and the guide wheel of walking mechanism is arranged on the upper flange left and right sides, guide wheel respectively with left and right upper spider guide rail engagement; Machinery deslagging assembly is to adopt cover push-and-pull clamping force balanced controls and filter chamber lower seal structure and expansion material shaking mechanism; The screen pipe unit of filter element is hung under upper flange; The vertical axis of the oval profile of the level cross-sectionn of the screen pipe unit of all filter elements all is parallel to each other, and this vertical axis and squeeze force direction are perpendicular; Push-and-pull clamping force balanced controls are opened the sealing gasket of filter chamber lower seal structure, and filter cake is discharged from the mouth of pipe of bottom, screen pipe unit;
Along in the screen pipe unit of the folded filter element between squeeze force direction pressing plate and last bearing plate assembly, push-and-pull clamping force balanced controls of clamping between every two adjacent screen pipe unit, these push-and-pull clamping force balanced controls comprise forward and backward swing bearing plate, back and forth executing agency, up and down push-and-pull lobe plate, running mechanism and trunnion axis; Back and forth executing agency adopts the fluid dynamic piston cylinder, the axis of trunnion axis be horizontal line and with the squeeze force perpendicular direction, the guide wheel of running mechanism is arranged on the trunnion axis left and right sides and support level axle, guide wheel group respectively with left and right lower bearing bracket guide rail engagement; The hinged forward and backward swing bearing plate of fore-and-aft direction difference around trunnion axis; Up and down push-and-pull lobe plate of clamping in forward and backward swing bearing plate, the pressure-bearing inclined-plane, front and back of up and down push-and-pull lobe plate meshes with the inside of forward and backward swing bearing plate respectively, the outside of forward and backward swing bearing plate respectively with the outside engagement of adjacent screen pipe unit, the outer basifacial level of forward and backward swing bearing plate press pig's tongue all with the sealing lip place outside engagement of the slag-drip opening of the lower flow passage of adjacent screen pipe unit; The hunting range of the angle ￠ of forward and backward swing bearing plate is that the intermeshing pressure angle of 10 °～135 ° up and down push-and-pull lobe plates 27 is 25 °～65 °; The left and right sides that up and down push-and-pull lobe plate centre bore is hinged on respectively trunnion axis is passed in the upper end of the piston rod of two fluid dynamic piston cylinders that are symmetrical set along the squeeze force direction, and push-and-pull lobe plate in up and down is fixed on the fixing sliding shaft sleeve of the upper end cover of fluid dynamic piston cylinder; Under the effect of fluid dynamic piston cylinder, push-and-pull lobe plate in up and down can move up and down along piston rod, and forward and backward swing bearing plate opens or closure thereby drive.Utilizing the push-and-pull clamping force balanced controls of the bearing plate of pressing structure is the critical component of flexible tube presser, these parts relate to the sealing of filter element filter chamber and exert pressure, owing to the screen pipe unit having adopted the multilayer porous disc, make the thickness of the middle part protuberance of screen pipe unit surpass the thickness of upper flange, make the liner of large-area middle bearing plate in design in the past inessential, and even can cancel, but the bottom of screen pipe unit dwindling sharply, or need this liner effect.This mechanism combines the balanced action of middle bearing plate and push-and-pull clamping force balanced controls, utilize the bearing plate of two swings to play the effect of liner and protuberance, satisfy the needs that pliable and tough screen pipe unit seals the uniform balance of needed transmission squeeze force and thrust; Push-and-pull clamping force balanced controls can be at suitable opportunity, the suitable height of protuberance with the swing bearing plate of liner between two screen pipe unit, bear keep suitable thrust to satisfy requirements of one's work.In the squeezing operation cycle, piston rod is fixed by trunnion axis, control element makes on pressurized fluid driven fluid dynamic piston cylinder and moves, push-and-pull lobe plate in up and down makes separately opened with certain angle of forward and backward swing bearing plate rotation, after swinging the bearing plate protuberance, the slag-drip opening place sealing lip of press filtration pipe unit reaches the purpose of closing filter chamber; The pressing plate reach, squeeze force moves down up and down push-and-pull lobe plate greater than the power of fluid drive fluid power piston cylinder, and the angle that the swing bearing plate opens is dwindled, and the effect of filter chamber transfiguration squeezing is satisfied in filter chamber attenuation simultaneously; Because the fluid driving force in the fluid dynamic piston cylinder that satisfies the needed sealed clamping power of filter chamber is constant all the time, up and down push-and-pull lobe plate and the pressure angle that swings between bearing plate are constant all the time, and sealed clamping power is also constant.Here should be noted that at up and down push-and-pull lobe plate and be in the limes superiors position, swing bearing plate because lever principle will produce strain, this rational strain can compensate the error of the depth of parallelism of two swing bearing plates of clamping screen pipe unit, the favourable specification requirement that reaches sealed clamping, the thickness that certainly swings bearing plate are the key parameters of controlling strain.
