Description
Technical field
The present invention relates to filter press equipment technical field, particularly relate to a kind of suspension beam type filter press and midway stopping automatic reduction method.
Background technology
Filter press is a kind of conventional solid-liquid separating equipment, is just applied to Chemical Manufacture in 18 beginnings of the century, is still widely used in chemical industry, pharmacy, metallurgy, dyestuff, food so far, brewages, pottery and the industry such as environmental protection.Specifically, filter press its be utilize a kind of special filter medium, certain pressure is applied to object, makes liquid dialysis a kind of plant equipment out.Its major function of filter press is: make solids extract in mixed liquor out, realizes the effect that solid, liquid is separated.
In general, if filter press, according to filter type classification, is mainly divided into four large classes: chamber-type press filter (chamberpressurefilter) and belt filter press (beltpressurefilter), membrane pressure filter, plate and frame filter press; In addition, above-mentioned plate and frame filter press structure specifically comprises: suspension beam type and side bar suspension;
Concise and to the point introduction is done to a kind of major constituents of traditional suspension beam type filter press of type below once:
Tradition suspension beam type filter press is primarily of five major part compositions: i.e. rack section (such as: thrust plate assembly, girder, pressure strip assembly, oil cylinder seat assembly), filtration fraction (such as: filter plate, diaphragm plate, filter cloth), arm-tie part (such as: pulling car, moment of torsion stop reversing arrangement), hydraulic part and electric control system.
Wherein, about above-mentioned rack section; Rack section is the basic components of filter press, and two ends are thrust plate and hold-down head, and the two connects persistent by the crossbeam of both sides, and crossbeam is in order to support filter plate, filter frame and pressure strip.A, thrust plate: it is connected with bearing and is seated on ground by one end of filter press, charging hole in the middle of the thrust plate of filter press, four angles also have four holes, and the hole of upper two jiaos is cleaning solution or squeezing gas feed, and lower two jiaos is outlet (undercurrent structure or filtrate (liquid).B, pressure strip: in order to compress filter plate filter frame, the roller of both sides rolls on the track of crossbeam in order to support compression plate.C, crossbeam: be supporting member.
Above-mentioned filter press compresses mode and mainly adopts electronic compression mode.Mechanical compaction: hold-down mechanism is made up of motor (overload protective device that configuration is advanced) decelerator, gear pair, screw mandrel and hold-down nut etc.During compression, motor rotates forward, and drives decelerator, gear pair, screw mandrel is rotated in Fixed Nut, promotes pressure strip and filter plate, filter frame is compressed.When thrust is increasing; motor load electric current increases, and when the large current value to protector setting, reaches maximum thrust; motor is cut off the electricity supply; stop operating, because screw mandrel and Fixed Nut have reliable self-locking helical angle, reliably can ensure the impaction state in the course of work; when returning; motor reversal, when the briquetting on pressure strip, returns stopping when pressing travel switch.At this moment, cut off motor power, compression action completes; Carry out pulling car advance subsequently, drive filter plate to return successively and carry out cake discharge operation, moment of torsion stop reversing arrangement needs constantly to implement commutation process to the pulling car of arm-tie part in the process.
About filtration fraction: filtration fraction by by the filter plate of certain sequential arrangement on girder, be clipped in filter cloth between filter plate, barrier film (barrier film type has) filter plate forms, filter plate, filter cloth (with membrane filter plate) alternately, define several independently filter elements--filter chamber.When filtering beginning, slip is under the promotion of feed pump, and the charging aperture on thrust plate enters in each filter chamber, and the pressure borrowing feed pump to produce filters.Due to the effect of filter cloth, solid is stayed in filter chamber and forms filter cake, filtrate is discharged by water nozzle (free flow) or liquid valve (undercurrent).Plate drawing system adopts that reciprocating drawing-plate mechanism efficiency is high, good corrosion resistance, working stability.Filter cloth washing device is independently running gear, and moved horizontally and vertical lift by motor driver, complete the cleaning to filter cloth, automaticity is high, and cleaning performance is good.
Obviously, the pulling car structure of analysis conventional suspension beam type filter press and process known: pulling car forms primarily of two shock hooks of pulling car main body and its end face that (two shock hooks all become crotch-shaped, be separately positioned on the end face of pulling car main body, and oppose in left and right sides; Namely left shock hook and right shock hook is respectively); In addition, arm-tie motor is main Power Drive Unit, and it drives drive sprocket to rotate by main chain, drive sprocket coaxial rotation is connected with driven sprocket and torque limiter simultaneously, obviously when pulling car advances, left shock hook first can clash into first piece of filter plate, is subject to reaction force; Now, reaction force will realize reversion (namely now first piece of filter plate is between left shock hook and right shock hook, and two shock hook clamping filter plates realize retreating cake discharge) by sensor equipment FEEDBACK CONTROL arm-tie motor; I.e. arm-tie motor reversal subsequently, pulling car drives first piece of filter plate to return, and realizes cake discharge operation; After pulling car is return and is put in place, again by clashing into commutation, and then arm-tie motor rotates forward again, drives pulling car to advance subsequently and prepares to implement cake discharge (the like to second piece of filter plate, constantly successively cake discharge is carried out to filter plate, until all cake discharge completes).
But, obviously, traditional suspension beam type filter press when arm-tie, if need in the middle of stop directly making arm-tie car (i.e. pulling car) reduce initial position time, this function cannot be realized.Stop terminating arm-tie action because original arm-tie bassinet structure cannot complete midway, so after all filter plates all can only execute the operation of arm-tie cake discharge by arm-tie car, could stop the action of end arm-tie, then get back to initial position.
To sum up, the technological deficiency how overcome in conventional art is those skilled in the art's technical problems urgently to be resolved hurrily.
