Description

A kind of adjustable filter press exchange system of precision

Technical field

It the utility model is related to filter press equipment technical field, more particularly to a kind of adjustable filter press commutation system of precision System.

Background technology

It is well known that filter press is a kind of common solid-liquid separating equipment, just it is applied to Chemical Manufacture in 18 beginnings of the century, extremely The present is still widely used for the industries such as chemical industry, pharmacy, metallurgy, dyestuff, food, brewing, ceramics and environmental protection.Specifically, press filtration It is to utilize a kind of special filter medium to machine, applies certain pressure to object so that one kind machinery that liquid dialysis comes out Equipment.Its major function of filter press is：The solids extract in mixed liquor is come out, realizes the effect of solid and liquid separation.

In general, if filter press is classified according to filter type, four major classes are broadly divided into：Chamber-type press filter (chamber Pressure filter) " and " belt filter press (belt pressure filter), membrane pressure filter, plate and frame filter press； Wherein, plate and frame filter press structure includes：Suspension beam type, side bar suspension；

Introduction brief once is done to the main construction of a type of traditional suspension beam type filter press below：

Traditional suspension beam type filter press (by taking traditional suspension beam type filter press as an example) is mainly made of five major parts：That is 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), Pulling plate part (such as：Pulling car, moment of torsion limiter reversing arrangement), hydraulic part and electric control system.

Wherein, on above-mentioned rack section；Rack section is the basic components of filter press, and both ends are thrust plate and compression Head, the girders of both sides connect the two persistent, and girder is supporting filter plate, filter frame and pressure strip.Thrust plate：It connects with bearing Connecing and one end of filter press is seated on ground, be charging hole among the thrust plate of filter press, there be four holes at four angles, and upper two The hole at angle is cleaning solution or squeezing gas feed, and lower two corners are outlet (undercurrent structure or filtrate (liquid) pressure strip：To press Tight filter plate filter frame, the roller of both sides roll to support compression plate on the track of girder.Girder：It is supporting member.

Above-mentioned filter press compresses mode and mainly uses electronic compression mode.(configuration is advanced by motor for above-mentioned hold-down mechanism Overload protective device) composition such as retarder, gear pair, screw and fixing nut.During compression, motor rotates forward, drive retarder, Gear pair, makes screw be rotated in Fixed Nut, promotes pressure strip to compress filter plate, filter frame.When thrust is increasing, electricity Machine load current increases, and when greatly to the current value of protector setting, reaches maximum thrust, motor is cut off the power, and stops turning It is dynamic, since screw and Fixed Nut have reliable self-locking helical angle, it can reliably ensure the impaction state in the course of work, retract When, motor reversal, when the briquetting on pressure strip, retracts stopping when pressing travel switch.At this moment, motor power is cut off, is compressed Action is completed；Pulling car advance is then carried out, drives filter plate to retract successively and carries out cake discharge operation, moment of torsion is spacing in the process Device reversing arrangement needs constantly to implement commutation processing to the pulling car of pulling plate part.

On filtration fraction：Filtration fraction be by be arranged in a certain order on girder filter plate, be clipped between filter plate Filter cloth, membrane (membrane type by) filter plate form, filter plate, filter cloth (with membrane filter plate) it is spaced, it is only to form several Vertical filter element -- filter chamber.When filtering starts, slurry enters each under the promotion of feed pump through the feed inlet on thrust plate In filter chamber, and the pressure produced by means of feed pump is filtered.Due to the effect of filter cloth, stay in solid and filter cake formed in filter chamber, Filtrate is discharged by water nozzle (free flow) or liquid valve (undercurrent).

It will be apparent that the pulling car commutation process of analysis conventional suspension beam type filter press is understood：Pulling plate motor is main moves Force driving device, its by main chain drive drive sprocket rotate, while drive sprocket rotate coaxially be connected with driven sprocket with And torque limiter (torque plate and inner side electronic section of the torque limiter primary outer are formed), it is clear that when pulling plate is small Chinese herbaceous peony into when, can first hit first piece of filter plate, be subject to reaction force；At this time, reaction force will be converted into torsion by main chain The amount of teetertottering (i.e. longitudinal force) of square disk；Again because torque plate, which will rock, touches tradition machinery formula sensor；This opportunity Tool formula sensor will experience contact switch touching signal, and then realized and inverted by signal feedback control pulling plate motor；With Post-tensioning board motor inverts, and pulling car drives first piece of filter plate to retract, and realizes that cake discharge operation (continuously sequentially opens plate to unload successively Cake, each only opening and mobile a piece of filter plate)；After pulling car is retracted in place, commutate further through hitting, and then pulling plate motor Rotate forward again, then drive pulling car advance prepare to implement second piece of filter plate cake discharge (and so on, constantly successively to filter plate Cake discharge is carried out, until whole cake discharges are completed).

It will be apparent, however, that the mechanical commutation mode of traditional filter press still remains technological deficiency；Analysis conventional suspension beam type Understood in the pulling car commutation process of filter press：Illustrate traditional exchange system (its tool of Fig. 1 and Fig. 2 referring to Fig. 1 and Fig. 2 Body illustrates pulling plate motor 1, main chain 2,5 structure of drive sprocket 3, torque plate 4 and sensor, while further illustrates pulling car The structure such as A and filter plate B, repeats no more as other structures)；After torque plate 4 is subject to longitudinal force, torque plate displacement touching machinery Formula sensor (i.e. sensor 5 in Fig. 1), i.e., hit mechanical sensor by torque plate, and then triggers the anti-of pulling plate motor 1 To movement, adjusted so as to fulfill the travel directions of trolley；In the process, with the axial for Z-direction of torque plate 4, same water Z axis vertical direction in plane is X-direction, and the Z axis vertical direction in same perpendicular is Y direction, at this time mechanically Sensor sensing torque plate realizes triggering pulling plate motor 1 especially by the displacement of sensing Z-direction)；It is it will be apparent that above-mentioned The traditional exchange system triggering precision being made of simple structures such as sensors is unadjustable.

To sum up, how to overcome the technological deficiency in conventional art is those skilled in the art's technical problem urgently to be resolved hurrily.
