Shown in continuing to refer to figure 1, spareslots outlet tube road, spareslots return line 205, precoating tank export to diatomite
Check valve is mounted on pipeline between the entrance of filter.The effect of these check valves is so that liquid can only be according to predetermined
Direction one-way flow, the case where without opposite direction flowing.Specifically, the check valve of spareslots outlet tube road is
So that turbid flows to diatomaceous earth filter from spareslots.Check valve on spareslots return line 205 is so that clear liquid is from diatom
Native filter flows to spareslots.Precoating tank the check valve exported on the pipeline between the entrance of diatomaceous earth filter be so that
Liquid can only flow to diatomaceous earth filter from precoating tank.
The coating wastewater equipment for reclaiming of the utility model use process is as follows:
Before work, add 3.5m in precoating tank 3023Deionized water, diatomaceous earth filter 301 is switched to pre- smearing
Formula is then turned on precoating pump 304 and is recycled.In cyclic process, the diatomite particle of 20KG is added in precoating tank 302, silicon
Diatomaceous earth particle enters in diatomaceous earth filter 301 with liquid, is retained by the stainless steel filter bag of 200 mesh, and filter membrane is formed.With
The continuation of circulation, the filter membrane formed in stainless steel filter bag is more and more thicker, just becomes filter cake.When liquid in precoating tank 302
It is more and more limpider, when precoating tank nephelometer 303 shows 0.1NTU, it can terminate to precoat.
When work, diatomaceous earth filter 301 is switched to normal production model: first adding 40m in spareslots 2013Go
Ionized water is then turned on spareslots Pump for giving-out 203.Under the action of spareslots Pump for giving-out 203, liquid passes through major trough return line
106 flow into major trough, and the liquid level of major trough 101 rises.After starting cleaning, rinses the turbid got off and also stay in major trough.It is turbid
Liquid is flowed in spareslots 201 by major trough overflow passage 105, and since the position of major trough 101 is higher, turbid is in gravity
Under naturally flow in spareslots 201.Turbid further flows into diatomaceous earth filter 301 by diatomaceous earth filter 301 from spareslots
It is filtered.After filtration, the solid content of liquid drops to 0.01% weight percent hereinafter, becoming clear liquid, and clear liquid passes through
Eight bag filters 306, check valve 307 return major trough 101 via major trough return line 106, dilute tank liquor in major trough 101
Solid content.The processing flow of diatomaceous earth filter 301 is 40m3/ h, 101 liquid capacity of major trough are 46m3, then average
The higher liquid of solid content in time major trough 101 of processing in 1.15 hours.
The effect of pressure gauge 204 is: when pressure gauge 204 value be greater than 6bar, illustrate diatom in diatomaceous earth filter 301
Native filter cake has been saturated, and needs replacing diatomite.The effect of double nephelometers 305 is: when one of them turbidity be higher than 5NTU, that
Illustrate that 301 stainless steel filter bag of diatomaceous earth filter has leakage, causes diatomite particle to enter liquid back pipe, signal is anti-at this time
It is fed to spareslots Pump for giving-out 203, so that spareslots Pump for giving-out 203 is shut down to be overhauled.The diatomite particle size of 400 mesh is
38 μm, it is 10 μm of filter bags by being mounted on precision in eight bag filters 306, a small amount of diatomite particle can be carried out
Filter, to prevent the problem of diatomite particle pollutes major trough 101.The design of the equipment has fully considered and perfect diatom
Native filter 301 is applied to the defect of paint industry.
The coating wastewater equipment for reclaiming of the utility model can be applied to automobile electrophoresis tank, it is ensured that vehicle body upper steel plate thickness
The positions such as higher threshold reach the film thickness of requirement for anticorrosion, nor the film thickness that will cause other regions is exceeded, avoids
The exceeded consumption of electrophoresis raw materials for varnish.
The coating wastewater equipment for reclaiming of the utility model realizes the requirement of industrial effluent reusing, processed recycle-water
Water standard can achieve the requirement that substitution deionized water is rinsed electrophoresis vehicle body.
Above-described embodiment, which is available to, is familiar with person in the art to realize or using the utility model, be familiar with ability
The personnel in domain can in the case where not departing from the utility model thought of the utility model, to above-described embodiment make various modifications or
Variation, thus the protection scope of the utility model is not limited by above-described embodiment, and should meet claims to mention
