Background technology

Because the different used emery wheel species of the material for processing part is also different, thus cooling for unlike material part with Lubricating system is also different.More and more extensive, the processing request more and more higher of part of existing graphite material class part application, mill Constantly change causes small grinding granule content more and more higher in grinding oil to add the abrasion of emery wheel to the amount of cutting, and reclaims grinding oil Quality worse and worse, have impact on the machining accuracy and surface roughness of part causes the amount of reprocessing or learies of processing part Increase, so as to add the use cost of equipment, the increase of environmental pollution, reduce production efficiency.Therefore, in filter type The filter aid that constant grinding oil is added when being recovered by filtration plays a part of being especially important.

Typically all used in existing technology on cellulose as the research of filter aid on the filter, it is necessary to first Film forming is precoated, is then further used, and the research that cellulose is used in graphite grinding particle occasion as filter aid does not almost have Have.

The content of the invention

The purpose of the present invention is to be helped in the recovery filtering of the grinding oil of the grinding of graphite material using cellulose The content of trickle graphite particle in filtering agent, control grinding oil, the usage cycles for improving grinding oil and the addition rationalized, are saved Equipment use cost simultaneously reduces the pollution to environment, improves production efficiency.

The invention provides following technical scheme：

Cellulose is ground the application of particle occasion in graphite, in the recovery filtering of the grinding oil of the grinding of graphite material Middle use cellulose does filter aid.

Cellulose adds the method addition in dirty oil without using the filter paper in precoat filtration machine or filter cloth directly as major ingredient, It is namely direct to add dirty oily hybrid filtering when adding cellulose；Comprise the following steps that：

Cellulose is quantitatively adding into the dirty fuel tank of filter by protected against explosion charger, dirty oil is by the dirty fuel tank Pipeline add in the dirty fuel tank, it is by the interior flow and elevator pump of the pipeline of the dirty fuel tank that cellulose and dirty oil is mixed Close, then cellulose is added in the filter with dirty oily mixture by the elevator pump and filtered.

It is preferred that, every 1000 liters of dirty oil is with containing 25.71-31.43 grams of cellulose in the mixed liquor of cellulose.

It is preferred that, average minute clock adds dirty oily 700 liters, intake cellulose 0.018-0.0212Kg, filtering surface per minute Filter effect is splendid when every square metre of filter paper of product or filter cloth need to add 100-200g celluloses.Namely mean if used 1 square metre of filter paper or filter cloth is filtered, and needs within every 10 minutes or so to change a filter paper or filter cloth that is filter Need paper feed or filter cloth once within every 10 minutes or so.

It is preferred that, the length of cellulose is 200um.Larger graphite particle can be wrapped up, it is not necessary to use special dirty oil Collecting box carries out preliminary treatment to remove large particulate matter to save equipment cost to dirty oil.

Advantages of the present invention：

Fiber have excellent disintegrate-quality, special economic saving, can be handled with the mode of environmental protection, harmless, reliably High efficiency, greatly improves making precision, by compared with other products, such as diatomite as filter aid, cellulose Consumption can reduce 70%.In practice this means that reducing consumption and substantially reducing sediment, while it is surplus to reduce sediment explanation The reduction of remaining filtrate, it means that reduce the loss of product in the moist filtering precipitate of processing.Because it is fiber knot Structure, jagged surface and macrovoid volume, can bring higher flow velocity.Filter run is longer simultaneously.The bullet of fiber Property reaction be that pressure increases sharply, the spot failure in their grafting filtering materials and by internal bond makes follow-up cleaning more simple It is single.It is soft and wear-resisting due to cellulose, pipeline and water pump is respectively obtained more preferable protection.Because cellulose can form many skies The porous filter cake in hole, and have good dredging property, it is ensured that the service life of high-throughput and filter, the earning rate of product, contracting In the cycle of short pressing, add the content of dry in filter residue.Fiber can prevent the stain of filter cloth or filter paper simultaneously, facilitate Follow-up cleaning.

Cellulose absorption property is strong, unit weight light, and fineness is uniform, and pH value neutrality is nontoxic, and mixing uniformity is good, can be remarkably reinforced The rigidity and intensity of product, settling volume can improve the chemical action such as the heat-resisting, wear-resisting of product, insulation, anti-aging up to 95% Performance, cellulose, which is added, can make filter cloth or filter paper smooth, and lightweight, intensity is good, reduce and cause flexible because humidity changes, Filtrate clarity can be improved in filter cloth or filter paper, and accelerates filtering velocity.

Embodiment
