Description
Technical field
The present invention relates to a kind of press filtration device for discharging 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 to existing vertical press filtration sheet frame group exists: 1. the material after the press filtration be prone to the press filtration plate on the filter press cloth adhesion, make push pedal be difficult to material is pushed away the press filtration plate; 2. the thrust that is produced during discharging is prone to make filter press cloth to produce deformation, has a strong impact on follow-up press filtration effect; 3. inconvenience is cleaned in the replacing that makes filter press cloth that fixedly installs of filter press cloth, also influences the press filtration effect.Designed a kind of press filtration device for discharging in the industry for this reason; Reel that its two ends that are included in press filtration plate top cover are provided with respectively and the filter press cloth that volume has on reel; The motor traction lower edge reel that described filter press cloth is provided with at press filtration plate two ends rolls, and makes material on filter press cloth, accomplish press filtration or discharging.Yet above-mentioned press filtration device for discharging is when reality is used, and filter press cloth can stretch elongated, so the motor that is provided with of press filtration plate two ends is with the identical distance that rolls when said filter press cloth is rolled, and the lax phenomenon of filter press cloth appears in regular meeting, and then influences the press filtration effect.Yet when regulating the degree of tightness of filter press cloth, not only increased the operating process of producing, and in case operation excessively, also can cause mechanical damage to filter press cloth or entire equipment through motor.
In order to reach the technique effect that mechanical part rebounds automatically; Chinese patent CN102182803A discloses a kind of stretcher that is used for tension band, and it comprises support housing (12) that limits spring cavity (16) at least in part and the arm (14) that attaches to said support housing (12) pivotly.One spring (18) is arranged in the spring cavity (16), and it is operably connected to arm (14) and support housing (12), with biasing arm, thereby arm is pivoted with respect to support housing.Spring (18) is a kind of round wire wind spring that does not load axial height (h) that has, and wherein, the height (H) that spring cavity (16) has is greater than the not loading axial height (h) of spring (18).Chinese patent CN 200946059 discloses a kind of pipe crimping device easy to use; Comprise shell body, rotating disk, axle core component, rotating disk spline assembly, water pipe and water inlet assembly; Said axle core component comprises rotating shaft, wind spring; Be characterized in that said spline assembly comprises the movable ratchet that is installed on said rotating disk sidewall, can make the resetting means of location, ratchet both sides and is arranged at the stop part on the said shell body inwall, said water pipe cooperates holding to make rotating disk stop to turn round to locate through said ratchet outer end and stop part pulling out the back.The present invention reaches the structure that stop part is set owing to be employed in the resetting means that ratchet is set on the rotating disk and the ratchet both sides are located on the inwall of shell body; Thereby in use; Both can be through the length of pipe location that cooperates holding to make to pull out of the ratchet on the rotating disk and stop part, and after using, can make in the automatic rollback pipe crimping of the water pipe of the pulling out device and collect, extremely easy to use; And simple in structure, install simple and easyly, can be widely used in the sprinkling irrigation operation in various places.Chinese patent CN201661230U discloses a kind of flexible screen window and has belonged to building element, the screen window that particularly can stretch.A kind of flexible screen window comprises window frame, it is characterized in that: the elasticity spool that it is wind spring that an end of window frame is being fixed an inner core, be tied with gauze on the spool, and the end that gauze exposes is equipped with hook, and the other end of window frame is provided with and buckles.Beneficial effect of the present invention: during use gauze drawn back and hang over just buckling on the window to hook and can fix by gauze, when not using take off hook, gauze is with the automatic rollback of elasticity spool.Gauze twists on the spool, can arbitrarily stretch out and withdraw the little printing opacity that do not influence of volume during withdrawal, safety easy to use.In sum, though above-mentioned patent document all adopts elastomeric element to realize automatic Telescopic, in the pressure filtering technique field; Also do not have any about utilizing the elastic mechanism technical information of flexible filter press cloth automatically; Its reason is that described filtering equipment is bulky, and filter press cloth is heavy; General elastic mechanism is difficult to drag wet heavy filter press cloth, and the technical parameter of the elastic mechanism of selecting for use to the filter press cloth of fixed dimension and weight is a large amount of limited number of time full size field tests of needs and definite.
