Description
Technical field
The present invention relates to the Separation of Solid and Liquid field, be specifically related to a kind of tightening mechanism for opening and closing of filter press.
Background technology
Well-known filter press need compress filter plate to form airtight filter chamber, so that carry out the press filtration of suspension.Press filtration needs to draw back filter plate after finishing, with the filter cake in the removal filter chamber.Compress filter plate and finish, draw back filter plate and finish, also can hold a concurrent post, save complicated drawing-plate mechanism by hold-down mechanism with special drawing-plate mechanism with hold-down mechanism.Hold-down mechanism is by being fixed on bearing plate on the bearing, can forming with respect to the pressure plate of bearing plate back and forth movement and the transmission device that drives the pressure plate motion.The main effect of transmission device is to drive pressure plate to compress the most filter plates that are arranged between bearing plate and the pressure plate, forms airtight filter chamber, and this requires transmission device to produce very big thrust reposefully.Hold-down mechanism can also the double as drawing-plate mechanism, draws back the filter plate of bunchiness, and it is high-speed that this needs transmission device to produce.Common transmission device has hydraulic cylinder type and electric screw formula.Hydraulic cylinder type promotes pressure plate with piston rod and compresses filter plate, is convenient to realize that high pressure compresses and draws back at a high speed.Existing problems are can not latched position after compressing, and owing to hydraulic system leakage needs ftercompction, increase the wearing and tearing of energy consumption and hydraulic pump during use.The electric screw formula promotes pressure plate and compresses filter plate with the mode of screw rod with pushing, can latched position after compressing, need not ftercompction.But the speed of service of electric screw formula is slow, compress filter plate after screw rod bear pressure, poor stability, bearing capacity is little, only is used for the filter press than small dimension in the past, can not adapt to the needs of big specification filter press and long stroke.Needing under the big situation of stroke, it also is that defective to be overcome is arranged that above-mentioned hydraulic cylinder type and electric screw formula hold-down mechanism take up room greatly.
In order to realize that high pressure compresses, long stroke draws back and closed filter plate, reduces the shared space of hold-down mechanism simultaneously fast, a kind of improved hold-down mechanism changes bearing plate movably into, with 4 long stroke fast hydraulic pressure cylinders come and go mobile bearing plate with draw back, closed filter plate, with an other cover Driven by Hydraulic Cylinder detent mechanism bearing plate is located behind the closed filter plate.Compress filter plate with 2～4 high pressure Driven by Hydraulic Cylinder pressure plate in addition.The advantage of this hold-down mechanism is and can opens and closes filter plate by long fast stroke that the minimizing that takes up room, but structure and control system complexity cause cost to increase and maintenance workload strengthens.
Summary of the invention
The objective of the invention is to avoid the shortcoming of above-mentioned hold-down mechanism, create a kind of compact conformation, economic and practical tightening mechanism for opening and closing, with the long stroke that adapts to big specification filter press draw back filter plate, closed filter plate fast, compress filter plate, the needs of locking filter plate position.
A kind of tightening mechanism for opening and closing that is used for filter press provided by the invention, it comprise the bearing plate of fixed-site, relatively the bearing plate back and forth movement pressure plate, have the transmission mechanism of prime mover, the screw pair that driven by transmission mechanism with screw rod and nut.Described screw pair is arranged in the both sides of bearing plate and pressure plate in pairs, and the two ends of screw rod connect with bearing plate and pressure plate respectively.Described pressure plate can be under screw pair drives back and forth movement.When starting tightening mechanism for opening and closing, or draw back filter plate, or closed filter plate, and compress filter plate in the mode of drawing over to one's side, compress filter plate after screw rod bear pulling force, the stop position of pressure plate is constant by the screw pair locking.
One embodiment of the present invention is that described transmission mechanism and the nut combinations that is driven by it rotation are integral, and is installed on the pressure plate, and the screw flight end is meshed with nut, and the other end and the bearing plate of screw rod are fixedly connected.When starting the rotation of transmission mechanism drive nut, nut and transmission mechanism move along the screw axis direction together with pressure plate.
Two of embodiment of the present invention are that described transmission mechanism is installed on the bearing plate, and nut is fixed on the pressure plate.The screw flight end is meshed with nut, and the other end of screw rod connects with transmission mechanism.When starting the transmission mechanism drive screw turns, nut moves along the screw axis direction together with pressure plate.
According to the present invention, the transmission mechanism of conjugate spirals pair is mutually chain guaranteeing its synchronous operation with mechanical interlocking device (for example travelling gear or driving-chain), or with separately synchronous prime mover, or with servo techniques to guarantee its synchronous operation.
The invention has the advantages that and integrate the function of drawing back filter plate, closed filter plate, compressing filter plate and locking filter plate position; The stroke that opens and closes filter plate is big, and speed is fast; Screw rod bears pulling force after compressing filter plate, and bearing capacity is big; Simple and compact for structure.
