Oil mist separator vacuum waste oil collecting device
Technical field
The present invention relates to a kind of auxiliary device of FDY winding apparatus, specifically is a kind of oil mist separator vacuum waste oil collecting device.
Background technology
Along with China's polyester filament industrial expansion, developed into the breakthrough of quality by the increase of amount.Differential polyester filament products such as various thin dawn, super fine denier, fire-retardant, emulation silk, full-dull because its good performance and higher added value, become the leading product in market gradually.But in the production of traditional polyester filament, side-blown cooling forming technology is adopted in spinning, and its filament number only can reach about 1.0dtex, and lower, the less stable of quality of silk.Produce thinner quality, make its filament number reach below the 0.5dtex even reach 0.2dtex, will adopt spinning technique technology such as island method could produce, this technology, productive capacity is lower, subtracts the alkali number processing owing to employing simultaneously, and energy consumption and blowdown are higher.Therefore, adopt differential polyester filament products such as later-model EVO ring blowing apparatus thin dawn of production, super fine denier, fire-retardant, emulation silk, full-dull in enormous quantities.Adopt ring blowing cooling forming technology, produce thin dawn, super fine denier product, compare with cross air blow cooling forming technology; The quality of silk has obtained great lifting; Its cooling air quantity will reduce significantly, can cut down finished cost greatly, increase economic efficiency.
Yet an equipment is spun in 20 of FDY ring blowings, and each high temperature roller spare is to rely on mist of oil to carry bearing is lubricated in high-speed operation, and passes through negative pressure mist of oil ducting to the vacuum oil mist separator, carries out mist of oil and separates.But because oil mist separator is under the negative pressure state, make isolated lubricating oil be not easy to discharge oil mist separator, if untimely with the waste oil discharge, with the normal operation that has influence on a whole set of ring blowing FDY equipment.In order to address this is that, the equipment personnel carried out multiple trial, such as fast inserting is installed in the oil mist separator lower end; Plastic pipe with diameter 14mm is connected oil storage on the little Plastic Drum, fills through ten days oil storage kegs, necessary oil extraction; Pull out fast inserting during oil extraction, the waste oil in the oil storage keg is outwelled.Oil extraction is frequent, and plug causes joint gas leakage easily repeatedly, not only wastes time and energy, and the oil mist separator oil-collecting too much influences FDY ring blowing apparatus and normally moves.
Summary of the invention
The purpose of the utility model provides a kind of oil mist separator vacuum waste oil collecting device, solves FDY ring blowing oil mist separator and is under the negative pressure state, smoothly isolated lubricating oil is discharged, and assurance equipment normally moves, and produces stable.
A kind of oil mist separator vacuum waste oil collecting device is characterized in that being made up of catchment cup, vacuum blowdown valve, draining valve, valve, bend pipe and straight tube.One end on catchment cup top connects the vacuum blowdown valve, and the other end connects straight tube, connects valve and bend pipe on the straight tube, and the bottom of catchment cup connects draining valve.
Described catchment cup is characterized in that it being to adopt the transparent plastic material material, is convenient to observe oil-collecting situation and sealing.
Described straight tube is characterized in that diameter is 30mm.
Described valve is characterized in that it being to adopt ball valve.
The progressive effect of the utility model is:
1. simple, convenient.
2. good airproof performance can make the negative pressure of catchment cup and oil mist separator be consistent, and waste oil can flow in the catchment cup automatically, stops waste lubricating oil trapping phenomena in the oil mist separator, guarantees well-equipped operation.
3. with coordinative composition of equipments, good looking appearance, do not take up space.
Description of drawings
Fig. 1 is the scheme drawing of the utility model waste oil collecting device.
Wherein: 1 is collection cups; 2 is the vacuum blowdown valve; 3 is draining valve; 4 is straight tube; 5 is bend pipe; 6 is valve.
The specific embodiment
Further specify the technical scheme of the utility model through specific embodiment:
The vacuum waste oil collecting device of the utility model is to be connected on the oil mist separator of FDY ring blowing apparatus through bend pipe 5.During use, observe waste lubricating oil through transparent catchment cup 1 earlier and collect situation, when waste lubricating oil is collected fast expiring; Ball valve on the gathering-device 6 is closed; Be vacuum state in the catchment cup this moment, opens 2 pressure releases of vacuum blowdown valve, so that waste oil is discharged smoothly; Open the draining valve 3 of catchment cup bottom at last, waste lubricating oil is discharged smoothly.After the waste oil emptying, close draining valve and vacuum blowdown valve, open ball valve, proceed waste oil and collect.
Oil mist separator vacuum waste oil collecting device, simple, convenient; Good airproof performance can make the negative pressure of catchment cup and oil mist separator be consistent, and waste oil can flow in the catchment cup automatically, stops waste lubricating oil trapping phenomena in the oil mist separator, guarantees well-equipped operation.
