Abstract

The utility model designs a turbine oil purifying device, belonging to lubricating system. The turbine oil purifying device is composed of a coacervation net, a bag filter, a blower fan and a pump. The turbine oil purifying device is characterized in that the bag filter 2 is formed into a closed body by a filter upper plate 7 and a filter lower plate 9 provided with holes through a middle meshed skeleton 8, and screw rods 10 are used to clamp and position the upper and the lower plates. A cover plate 6 is positioned on the filter upper plate 7, and a plurality of bag filters 2 are fixed on the cover plate 6 by the screw rods 10. A pump 5 is arranged on the ground of the outer side of the turbine oil purifying device, and the inlet of the pump 5 is connected with a flange arranged outside the turbine oil purifying device via a pipeline. The other end of the pump is connected with an impulse type automatic backflushing filter 4 which is fixed on the outer side plate of the turbine oil purifying device.

Description

Turbine oil purifying device

The utility model belongs to special filtration machinery, and specifically it is used in the lubrication system of Turbo-generator Set, isolates moisture content and various solid shape mechanical admixture from lubricant oil, is called the turbine oil purification plant.

Nozzle and check valve are arranged at the bag filter top of turbine oil purification plant at present, a cover on each bag filter, in the turbine oil purification plant of some tens of cover nozzles and check valve are arranged greatly, structure is very complicated, and its filtration facility is a kind of filtering tank that uses bronze filtering element (cartridge), huge benzene is heavy, the selling at exorbitant prices of bronze filter core is easily stopped up, and it is difficult to clean, replacing is many, and it is very inconvenient to use.

The purpose of this utility model then is the problem at above-mentioned existence, has designed a kind ofly to need not nozzle, check valve, and has adopted automatic backwashing filter to remove the turbine oil purification plant of mechanical admixture.

Technical solution of the present utility model:

The turbine oil purification plant is connected in parallel in the lubrication system, utilize the inner cohesion net of this device, bag filter, evaporation, exhaust facility, constantly get rid of small water droplet, usually the small water droplet of 0.01mm～0.03mm all can effectively be separated, and remove various mechanical admixtures with another kind of automatic backwash filtration facility, the turbine oil purification plant is characterized in that bag filter 2 forms closure by filter upper plate 7 and filter lower plate 9 with holes by middle mesh skeleton 8, by 10 pairs of upper and lower plates clamping location of screw rod, cover plate 6 is positioned on the filter upper plate 7, several bag filters 2 are fixed on the cover plate 6 by screw rod 10, and pump 5 is on ground, the turbine oil purification plant outside, and pump 5 inlets are linked to each other with the device body outer flange by pipeline, the other end and pulsed automatic backwashing filter 4 connect, and pulsed automatic backwashing filter 4 is fixed on the device outer panel.

The utility model advantage: the filtration facility of the removing mechanical admixture in the turbine oil purification plant has been used automatic back-flushing filtering device, obstruction on the removing filter screen that can go round and begin again automatically keeps filter screen clean for a long time, in service needn't the cleaning, and the low price several times, structure is light; Bag filter is being constructed get on to have disappeared nozzle, check valve structure, adopts horizontal screen subtype structure, is divided into some groups, every group of several bag filters, plane are consolidated on the surface plate with holes, and are affixed with casing again, make technology greatly simplify, cost further descends, and does not influence using effect.For other industry, separate from first liquid as need and to sneak into another kind of second liquid wherein insoluble, big proportion, this device also can be used.

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the utility model bag filter schematic representation; Fig. 3 is the utility model automatic backwash secondary cleaner schematic representation.

1 is the cohesion net among Fig. 1, the 2nd, and bag filter, the 3rd, blower fan, the 4th, automatic backwash secondary cleaner, the 5th, pump.

6 is that cover plate is a perforated flat plate among Fig. 2, the 7th, and filter upper plate, the 8th, mesh skeleton, the 9th, filter lower plate with holes, the 10th, screw rod.

11 is bypass valve among Fig. 3, the 12nd, and shielding can, the 13rd, cup-strainer core, the 14th, blowdown chamber, the 15th, housing.

Below in conjunction with accompanying drawing the utility model is further described:

The turbine oil that needs to purify comes from main fuel tank stream, upwards flow in the bottom that enters cohesion net 1 through stopcock, overflow into the cell of bag filter 2, bag filter 2 is to be immersed in the oil of this cell, oil enters its inner chamber all around with the bottom from bag filter 2, and overflow cell, and flow to the reservoir compartment by the perforated flat plate 6 on its filter upper plate 7.

Bag filter is upper and lower to be filter upper plate 7 and filter lower plate 9 with holes, the centre is a mesh skeleton 8, and play reinforcement and set off effect with two screw rods 10, some bag filters are fixing on the cover board by the screw rod that himself has, cover plate and purification plant housing inner gimbal link, and driving fit, oil can only overflow from filter upper plate 7 of bag filter own and corresponding with it perforated flat plate 6, to play the effect that coarse filtration and capillary adsorbed water drip.Purification plant is a casing, wherein be divided into some cells, and parts all are fixed in the corresponding cell, cohesion net 1 is forwardly tilting, and oil moves from bottom to top, overflows into the cell of bag filter 2, the adjacent room of these two cells (the figure special secondary school draws), be the oil of storing to come, squeeze into automatic backwash secondary cleaner 4, filter and flow back to main fuel tank by oil pump 5 from the overflow of bag filter cell.So circulation is carried out, and reaches standard-required.

Automatic backwash secondary cleaner 4 mainly is made up of with cup-strainer core 13 housing 15, shielding can 12, and housing 15 plays sealing and reaches and the effect of outer tube communications and liaison knot; Shielding can 12 makes the housing grease chamber divide upper and lower two-part, play oily conductance simultaneously to effect, and the sump oil that can avoid sinking refluxes again; Cup-strainer core 13 is this part main body, also divides upper and lower two halves, and first is an oil motor, and second is the blade type pulse pump of Periodic Rotating; Bypass valve 12 shields, make secondary cleaner whenever do not understand in the circulation of oil-break, concentrate and the water conservancy diversion dirts blowdown chamber 14.
