Description
Technical field
The present invention relates to a kind of discharge device for filter pressing and method of work thereof of auto-tensioning filter press cloth, belong to the technical field of sludge press filtration.
Background technology
The deficiency that the mode of carrying out discharging for existing vertical filtrating-pressing plate frame group exists: the 1. filter press cloth adhesion of the material after press filtration easily and on filter press plate, makes push pedal be difficult to material to push away filter press plate; 2. the thrust produced during discharging easily makes filter press cloth produce deformation, has a strong impact on follow-up press filtration effect; 3. being fixedly installed of filter press cloth makes the replacing of filter press cloth clean inconvenience, also affects press filtration effect.Devise in the industry a kind of discharge device for filter pressing for this reason, the reel that its two ends being included in filter press plate top cover are arranged respectively and the filter press cloth rolled up on reel, described filter press cloth rolls along reel under the motor that filter press plate two ends are arranged draws, and makes material on filter press cloth, complete press filtration or discharging.But above-mentioned discharge device for filter pressing is when reality uses, filter press cloth can stretch elongated, therefore the motor that arranges of filter press plate two ends with identical roll distance described filter press cloth is rolled time, often there will be the phenomenon that filter press cloth is lax, and then affect press filtration effect.But when regulating the degree of tightness of filter press cloth by motor, not only add the operating process of production, and once operation excessively, also can cause mechanical damage to filter press cloth or whole equipment.
In order to reach the technique effect that mechanical part rebounds automatically, Chinese patent CN102182803A discloses a kind of stretcher for tension band, and it comprises the support housing (12) limiting spring cavity (16) at least in part and the arm (14) attaching to described support housing (12) pivotly.One spring (18) is arranged in spring cavity (16), and it is operably connected to arm (14) and support housing (12), with biasing arm, thus makes arm relative to support housing pivotable.Spring (18) is that one has the round wire wind spring not loading axial height (h), wherein, what the height (H) that spring cavity (16) has was greater than spring (18) does not load axial height (h).Chinese patent CN 200946059 discloses a kind of pipe-reeling device easy to use, comprise shell body, rotating disk, axle core component, rotating disk spline assembly, water pipe and water inlet component, described axle core component comprises rotating shaft, wind spring, be characterized in the stop part that described spline assembly comprises the movable ratchet being installed on described rotating disk sidewall, the resetting means that ratchet both sides can be made to locate and is arranged on described shell body inwall, described water pipe is located with stop part coordinating holding to make rotating disk stop turning round by described ratchet outer end after pull-out.The utility model arranges ratchet and the resetting means that ratchet both sides can be made to locate and the structure arranging stop part on the inwall of shell body owing to adopting on rotating disk, thus in use, both with the coordinating holding of stop part, the length of pipe of pull-out was located by the ratchet on rotating disk, and after using, the water pipe automatic rolling of pull-out can be made again to return in pipe-reeling device collect, extremely easy to use, and structure simple, install simple and easy, can be widely used in the sprinkling irrigation operation in various place.Chinese patent CN201661230U discloses a kind of flexible screen window and belongs to building element, the screen window that particularly can stretch.A kind of flexible screen window, comprises window frame, it is characterized in that: it is the elastic reel of wind spring that one end of window frame is fixed wtih an inner core, and spool is tied with gauze, and hook is equipped with in one end that gauze exposes, and the other end of window frame is provided with and buckles.The beneficial effects of the utility model: pulled open by gauze during use and just can fix by gauze hanging over buckling on window, when not using, hook is taken off, gauze is with the automatic rollback of elastic reel.Gauze twists on spool, can arbitrarily stretch out and retract, and during retraction, volume is little does not affect printing opacity, safety easy to use.In sum, although above-mentioned patent document all adopts elastomeric element to realize automatic telescopic function, but in pressure filtering technique field, also do not have any technical information about utilizing elastic mechanism automatic telescopic filter press cloth, its reason is, described filtering equipment is bulky, and filter press cloth is heavy, general elastic mechanism is difficult to drag wet heavy filter press cloth, and for fixed dimension and weight filter press cloth selected by the technical parameter of elastic mechanism need a large amount of limited number of time full size field test and determine.
