Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme is further described.
Refering to Fig. 1, this dual-effect refrigeration and the structure of extra accuracy filter plant equipment and work process it is:
One-level coarse filtration is filtered to three grades of essences:
Dirty liquid input to coarse filter device R1 of band slag is done coarse filtration by pumping P via pipeline L8 and is processed by the dirty liquid in lathe dirty fuel tank M；
Dirty liquid after coarse filter device R1 processes does essence filtration treatment by pipeline L9 input to fine filtering apparatus R2, concrete, the dirty liquid after coarse filter device R1 processes carries out essence filtration treatment by pumping P4 via the dirty liquid district T4 belonging to pipeline L13 suction fine filtering apparatus R2；
When control valve V1 is opened; dirty liquid in dirty liquid district T4 is by filter pump P1, pipeline L and pipeline L2; suction superfinishing filter vat F1 does superfinishing and filters and carry out backwash; in order to promote the service life of filter element, before superfinishing filter vat F1 carries out automatic backwash, control valve V1 is automatically switched off; control valve V2 automatically opens up; entering superfinishing filter vat F2 via pipeline L3 and carry out superfinishing filtration, a preparation and a use designs, it is to avoid shut down cause shutdown to treat work is lost.
Scrape oil slick to process:
When in bucket, cutting fluid contains the oil slick such as substantial amounts of track oil and will effectively cause the rotten damage of cutting fluid, produce stench etc., this device devises scrapes oil slick device, this is scraped oil slick device and includes fuel tank, oil slick relief area T1 and oil slick concentration zones T2 it is divided in fuel tank, oil slick relief area T1 is for being concentrated to relief area by oil slick in case, oil slick concentration zones T2 is entered back into after assembly, oil slick concentration zones T2 arranges oil slick self-fractionating pump P3, for oil slick is scraped, and be emitted in oil slick recycling bin C, take out after expiring and reclaim.
Dual-effect refrigeration processes:
The refrigeration modes that the present embodiment provides uses double-compressor design, compressor Y1 and compressor Y2, coolant in compressor Y1 enters coolant in plate heat exchanger B1 via pipeline Y1-1, coolant is gone out again by pipeline Y1-2, thus reach the purpose of equilibrium temperature, coolant in compressor Y2 enters coolant via pipeline Y2-1, then goes out coolant via pipeline Y2-2, thus reaches the purpose of main shaft equilibrium temperature.
After superfinishing filter vat F1, superfinishing filter vat F2 filtration, clean liquid is respectively via pipeline L10 and pipeline L11, plate heat exchanger B1 is entered again via pipeline L10-1, start refrigeration, liquid after refrigeration enters lathe or T3 liquid case via pipeline L10-2 and pipeline L12-1 the most respectively, axis system refrigeration is to use special fuel reserve tank T5, again with pumping P5 via pipeline L16 suction plate heat exchanger B2, after plate changes refrigeration, sent into main shaft S by pipeline L17 again.
The embodiment of the present invention also uses two kinds of fuel system, illustrates below in conjunction with filter process:
nullPower save mode: superfinishing filter vat F1、Clean fluid suction lathe after refrigeration after superfinishing filter vat F2 filters uses，For reaching energy-conservation，Employing direct type designs，Directly enter B1 refrigeration machine metal plate swap-in mouth via L10 and L11 pipeline through L10-1 pipeline，Liquid after refrigeration is sent by L10-2 again，Via L12 pipeline, superfinishing filter vat F1 filtration and the clean oil suction lathe after refrigeration are used，When (predeterminable time) before backwash，Control valve V1、V2 opens，Allow: superfinishing filter vat F1、Superfinishing filter vat F2 filters to avoid the lathe liquid that breaks to cause workpiece and tool damage to produce waste product simultaneously，Time can set according to demand，Now: superfinishing filter vat F1、The clean liquid that superfinishing filter vat F2 filters out is sent into lathe by pipeline L10 and L11 via pipeline L12 and is used，Setting control time one arrives，Superfinishing filter vat F1 backwash，Superfinishing filter vat F2 filters，This design can ensure that lathe continues feed flow，Thus production cost can be saved.
Equipment carries out backwash, and superfinishing filter vat F1, superfinishing filter vat F2 recoil, and control valve V3, V4 open, and band slag waste liquid is first via pipeline L4, L5, then enters essence filter vat R2 via pipeline L6 and try again recovery, reaches the purpose of environmental protection and energy saving.
High stable fuel system: for ensureing that fuel feeding is stable or pressure, can additional lathe solution feed pump P2, send into lathe via pipeline L7 and use.Concrete, when using this fuel system, the clean liquid filtered out be directly from superfinishing filter vat F1, superfinishing filter vat F2 via pipeline L10, L11, the import of plate heat exchanger B1 is entered again via pipeline L10-1, fluid after refrigeration is sent by pipeline L10-2 again, again via pipeline L12, superfinishing filter vat F1 is filtered and in clean oil suction clean fuel tank T3 after refrigeration, then sent into lathe M by lathe solution feed pump P2 and pipeline L7 and use.
Above-mentioned detailed description of the invention; it is only technology design and the architectural feature of the explanation present invention; purpose is the stakeholder being familiar with technique can be implemented according to this; but above said content is not limiting as protection scope of the present invention; every any equivalence change made according to the spirit of the present invention or modification, all should fall under the scope of the present invention.
