Ceramic filter is a kind of solid-liquid separating equipment, in the equipment course of work, its filter medium filter plate will pass through suction strainer, drains, discharging, four continuous courses of work of backwash, moves in circles, and finished the cyclic process of above-mentioned four actions by distributing valve control rotor in a revolution.
Some circle ceramic filtering plates are housed as filter medium on the main shaft of ceramic filter, each circle is equipped with 12 filter plates, main shaft drive filter plate rotates in the feed chute of going forward side by side when work, the material that needs dehydration is housed in the hopper, and filter plate has passed through filter cake formation, cake dewatering, has peeled off and washed four-stage in a revolution.When dehydration, the water in the material is discharged after the filter plate micropore enters inside from the filter plate outside.When flushing, water outwards oozes out by micropore from filter plate inside, so the stage can be described as backwash again.After filter cake on filter plate was stripped from, the filter plate surface still had remaining material, and the micropore on the part filter plate has blocked situation, adopts the method for backwash like this, just can remove surface residues material and mediation micropore.
Glassware for drinking water during backwash has certain pressure, form the press water of 0.06Mpa to 0.08Mpa by filtration, decompression and constant-voltage system, enter the filter plate inner chamber by pipeline, distributing valve, under differential pressure action, outwards flow through the filter plate micropore, wash out material residual on the filter plate and mediation filter plate micropore, thereby reach the purpose of cleaning and ensureing filter efficiency.
In the job applications of reality, particularly after ceramic filter moves a period of time, often contained some become branch's fouling on filter plate in the material, stopped up the filter plate micropore, even backwash is arranged, also can't remove, so that the stopping state of ceramic filter can aggravate along with the lengthening of service time, therefore must regularly handle the fouling tendency material to these fouling tendency materials.
Summary of the invention
In order to overcome the scale formation of filter plate micropore, the utility model provides a kind of automatic mixing acid device of wash water, it is controlled automatically by microsystem, make the proportioning of acid, water in the mixed process realize control automatically, mixed acid solution is provided in the counter-flushing pipeline by certain flow automatically, mix once more with water in the counter-flushing pipeline according to the hydraulic pressure situation, finally reach the fouling tendency material in the dissolving filter plate micropore, the purpose of mediation filter plate micropore.
By its technical scheme of automatic mixing acid device that the utility model proposes be: on the position line at round center is crossed at the stainless steel drum top of a sealing, lead to and be furnished with into concentrated acid pneumatic ball valve and flanged fitting, water inlet pneumatic ball valve and flanged fitting, liquid level gauge, measuring pump in the bucket successively, wherein advancing concentrated acid pneumatic ball valve and flanged fitting is connected with the concentrated acid bucket by the concentrated acid pipe, water inlet pneumatic ball valve and flanged fitting are connected with running water pipe, the entrance point of measuring pump gos deep in the bucket, and its outlet is connected with counter-flushing pipeline.In addition, advancing sour ball valve, water intake ball valve, liquid level gauge and measuring pump all has circuit to link to each other with the Control System of Microcomputer of this device.
The utility model is made up of complex acid part, confession acid moieties and control system, complex acid part mainly by the stainless steel drum, advance concentrated acid pneumatic ball valve and flanged fitting, water inlet pneumatic ball valve and flanged fitting, liquid level is taken into account associated pipe and is constituted, and links to each other with control system.By giving the predefined value of control system, reach the quantitative control of into acid and water inlet, in drum, to obtain the diluted acid of certain proportioning.
The acid moieties that supplies of the present utility model mainly is made of pressure sensor in measuring pump, the counter-flushing pipeline and associated pipe, measuring pump has circuit to link to each other with control system with pressure sensor, when the pressure in the counter-flushing pipeline reached predefined force value, control system started measuring pump and supplies acid work.
Control system of the present utility model is made up of microcomputer and other electronic devices and components, is known technology.
Use this device, have the following advantages:
1, complex acid concentration is accurate, and its concentration can suitably be adjusted at any time, has stopped the instability and the fault phenomenon of artificial complex acid.
2, cleaning performance is good, cooperates other cleaning ways can thoroughly dredge the filter plate micropore, in time recovers the filter plate serviceability.
3, safe and reliable, stop potential safety hazard, reduced the labour intensity of artificial complex acid.
