Description
Technical field
The present invention relates to a kind of cold pilger mill field, particularly relate to a kind of cold pilger mill discharge end waste oil and reclaim recycling method.
Background technology
Cold pilger mill utilizes annular distance shape to carry out the process equipment of cold conditions rolling to hollow forging (i.e. base pipe), and cold pilger mill has good cogging performance, and stock utilization is high, and precision and surface roughness are all better than drawn tube.Be rolled in production at cold pilger mill, all must smear rolled lubricating oil to the base pipe entering roll, be beneficial to the roll forming to steel pipe.
After steel pipe is sent into and is rolled out in cold pilger mill, the surface of steel pipe and inwall can be stained with the ROLLING OIL in cold pilger mill, ROLLING OIL in such cold rolled tube handset can be brought out by steel pipe, need normal operation cold pilger mill oiling being maintained to machine of staff's not timing, and the ROLLING OIL of taking out of is generally wasted and contaminated environment.And the subsequent processes technique of steel pipe requires to clean up the rolling wet goods on steel pipe.
Therefore, how to complete the collection of cold pilger mill discharge end waste oil, purification and cycling and reutilization, reduce loss and the waste of ROLLING OIL, ensure the normal operation of cold pilger mill, guarantee that institute's rolled steel tube obtains good surface quality and pipe inside and outside wall cleannes simultaneously, alleviate the labour intensity of downstream process staff and reduce the cost of follow-up washing steel pipes and manually become a production difficult problem.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is: how to provide a kind of and implement conveniently, the cold pilger mill discharge end waste oil can realize the collection of cold pilger mill discharge end waste oil, purifying and recycle reclaims recycling method, make it have simple to operate, the effect that fluid removal effect is good.Can effectively reclaim in cold pilger mill by ROLLING OIL that steel pipe leads out, both ROLLING OIL had been avoided to waste, the surface quality of simultaneously rolled steel tube being carried out to surface and inwall carries out pretreatment with clean, and the workload reducing downstream process washing steel pipes, with artificial, reduces the production cost of enterprise simultaneously.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of cold pilger mill discharge end waste oil reclaims recycling method, it is characterized in that, at cold pilger mill discharge end, degreasing unit is set, by removing rolled steel tube outer surface fluid except tubing and casing, by air compressor machine jet removal rolled steel tube inner surface fluid, then collect fluid by precipitation fuel tank and filter, precipitate after be back to oil storage space bottom cold pilger mill, carry out recovery cycling and reutilization.
In the present invention, eliminate the fluid of rolled steel tube outer surface and inner surface, fluid is removed clean, it is high that fluid recycles efficiency simultaneously.The jet removal of air compressor machine in the fluid of simultaneously inner surface, easy to operate, and removal effect is excellent.
Specifically, the present invention first obtains the cold pilger mill drain oil recovery equipment of following structure,
This device comprises cold pilger mill, it is oil storage space bottom cold pilger mill, milling train oil pump is provided with in oil storage space, milling train oil pump is connected with the ROLLING OIL shower nozzle being positioned at milling train head inlet pipe end position by oil pipe, it is characterized in that, the discharge end outer wall of described cold pilger mill is provided with a precipitation fuel tank, described precipitation fuel tank upper surface near the downward-sloping setting in cold pilger mill one end and and the exit position of discharging guide pin bushing above the lowest part correspondence that connects of cold pilger mill discharge end outer wall be provided with oil trap, described oil trap is connected with the filter being positioned at precipitation fuel tank internal by the oil inlet pipe of bottom, described filter comprises surface and is provided with the housing of filter eye and is positioned at the filter core of enclosure interior, the discharge end outer wall of the cold pilger mill of described precipitation fuel tank lower inside is provided with return port be communicated with the oil storage space bottom cold pilger mill, also degreasing unit is provided with above described precipitation fuel tank, described degreasing unit comprise one be fixed on the discharge end outer wall of cold pilger mill except tubing and casing, except tubing and casing just to discharging guide pin bushing outlet arrange and internal diameter is greater than rolled steel tube external diameter, in oil removing casing tube internal hole, interval is furnished with at least two interior installation annular grooves be arranged circumferentially and is provided with O-ring seals in interior installation annular groove, this O-ring seals internal diameter and rolled steel tube external diameter coupling, removing in tubing and casing to being arranged with oil leak hole between described adjacent installation annular groove, described degreasing unit also comprises and is positioned at the air nozzle and an oil removing piston that precipitation fuel tank arranges away from cold pilger mill one end position, described air nozzle is connected with air compressor machine by tracheae, described oil removing piston entirety is in column and external diameter is less than rolled steel tube internal diameter, oil removing outer surface of piston vertically interval is furnished with at least two and outward installs annular grooves and install in annular groove outside and be provided with O-ring seals, this O-ring seals external diameter and rolled steel tube internal diameter coupling,
Then when cold pilger mill works, after rolled steel tube exports out from discharging guide pin bushing, directly enter into except pulling out from the other end in tubing and casing, complete by the O-ring seals in tubing and casing and the fluid of rolled steel tube outer surface is removed, make fluid from flowing out to below except tubing and casing two ends and oil leak hole and being collected by oil trap; After rolled steel tube outer surface fluid is removed, can again oil removing piston be inserted into rolled steel tube endoporus from rolled steel tube one end, then the oil removing piston by air nozzle aligning rolled steel tube endoporus is jet, promote oil removing piston by air-flow forced and drive the fluid in rolled steel tube endoporus to move to the other end from rolled steel tube one end, realizing the removal of rolled steel tube inner surface fluid; Fluid is after rolled steel tube removal, because precipitation fuel tank upper surface is obliquely installed and is provided with oil trap at lowest part, fluid can be collected like this, and make fluid enter into the filter in precipitation fuel tank by oil trap, in precipitated oil box cavity, fully purification is precipitated after completing filtration, upper clear supernate is back in the oil storage space bottom cold pilger mill by return port, can be evacuated to ROLLING OIL shower nozzle again use by milling train oil pump; So just achieve the automatic collection of cold pilger mill discharge end waste oil, purification and cycling and reutilization.
