Description
Technical field
The utility model belongs to machining equipment technical field, and system is filtered more particularly, to a kind of backpulsing cutting fluid
System.
Background technology
People are being machined, and such as this kind of metal of cutter, grinding machine is needed in product processing using a large amount of
Cutting oil, cutting fluid to cooling cutter and processing workpiece carry out cooling protection, cutting oil, cutting fluid be one in digital control processing
It is straight to recycle, but in use for some time, the impurity such as metal fragment will be contained in cutting oil, cutting fluid, and it is rotten
Discoloration is smelly, if the cutting after rotten is oily, cutting fluid is used further to processing cooling can reduce cooling effect, causes in digital control processing
The machining accuracy of the tool damage of the heart and influence processing workpiece, also results in processing workpiece discoloration, and smelly cutting oil, cuts
Cutting liquid can also influence workman's on production line healthy.So cutting oil, cutting fluid be accomplished by use for some time into
Row is changed, but the cutting discarded is oily, cutting fluid then directly pours into irrigation canals and ditches, and this can cause great environmental pollution.With
The continuous reinforcement of people's environmental consciousness, people are constantly exploring sump oil filtration system, and the cutting that will be discarded is oily, cutting fluid
Realize and reuse after filtering, common sump oil filtering is more to be carried out at sedimentation separation, filtering and absorption using sedimentation basin, filter cloth
Manage, and not only floor space is big, need constantly to change consumptive material for the facility in these methods, cost height, efficiency is low, after processing
Impurity easily causes secondary pollution with consumptive material, and filtering accuracy is not high, and such as vacuum types or other recoils regeneration filter core are because mistake
Filtering layer is extremely unstable, so precision can not ensure, particularly vacuum types filtering product, to accomplish high-precision by a very thin paper
Degree, is nearly impossible.
In order to solve the problem of prior art is present, people have carried out long-term exploration, it is proposed that miscellaneous solution
Scheme.For example, the applicant proposes a kind of sump oil no material consumption filter and its sump oil no material consumption filter method before this
[application number：CN201410025881.2], it includes the sump oil case for being used to deposit sump oil, and described sump oil case is connected with can be by dirt
Oil is separated into the rotary filter of absolute oil and impurity, described rotary filter and is provided with filter space, described sump oil case
Provided with for detecting the sump oil liquid level information in sump oil case and sump oil can be drained into filtering according to the sump oil liquid level information of detection
Dirty charge stock mechanism in space, described rotary filter is arranged in the filtering ponds body for placing absolute oil, and its feature exists
In, being provided with rotary filter side is used to clearing up and collect the deslagging device of impurity, described deslagging device by pipeline with
Refuse collector is connected, and described interior be provided with of pipeline is used to deliver combustion adjuvant and be compressed into after can combustion adjuvant be mixed with impurity
The block compression mechanism that feeds intake.In the structure, when the sump oil liquid level information in sump oil case reaches setting value, dirty charge stock mechanism
Sump oil is drained in filter space, sump oil is filtered into absolute oil and impurity by rotary filter, and absolute oil is flowed into filtering ponds body, miscellaneous
Matter is blocked in filter space, and impurity will be collected and fed into pipeline by deslagging device, and the compression mechanism that feeds intake is by combustion adjuvant and impurity
Be compressed into after mixing it is block form reusable fuel, seen off through refuse collector, realize the no material consumption filtering of sump oil with
Reuse and the impurity after filtering realizes twice laid.
Such scheme improves existing cutting oil filtrating machine consumptive material and wastes big, the problem of cost is high, with without secondary dirt
Dye, the advantages of no material consumption is filtered, but the program does not meet high-precision needs still, and filter efficiency has much room for improvement, and deposits
