Description
One, technical field
The utility model relates to the purifier of iundustrial oil, particularly the anti-vavuum pump fueling injection equipment of vacuum oil-filter.
Two, background technology
Vacuum filter Shan machine is that iundustrial oil purifies, the special equipment of regeneration, is widely used in the every profession and trade.Existing vacuum oil-filter mainly comprises filter, heater, vacuum separation tank, vavuum pump, oil drain pump, oil inlet pipe, oil exit pipe, exhaust tube, valve and control system etc., connect by pipeline therebetween, as lubricating oil, insulating oil, turbine oil, compressor oil, refrigerator wet goods iundustrial oil, in use because of make moist, water inlet, oxidation and particle contamination etc. are former thereby the quality of oil is descended, need through purify, the regeneration back recovers oily quality.Pending oil is in vacuum oil-filter, well cuts is sloughed in filtration through filter, heater via adds deep fat, in the deep fat under the vacuum state of unevaporated moisture in vacuum separation tank, produce low-temperature boiling and become gas, add deep fat and enter vacuum separation tank, carry out Oil-gas Separation in vacuum separation tank, the gas of separating is extracted out from exhaust tube by vavuum pump; The oil of separating by oil drain pump, becomes absolute oil after filtering through filter again and discharges, and re-uses, thereby has realized purification, the regeneration of vacuum oil-filter to iundustrial oil.
But in the vacuum separation tank of existing vacuum oil-filter, be by being arranged at the liquid level control switch output signal at tank body housing middle part, carrying out liquid automatic control by electric control system controls magnetic valve oil inlet quantity to the control of oil level.Existing vacuum separation tank mainly contains following weak point:
1, when processed fluid water content was hanged down than big or fluid heating-up temperature, a large amount of foams of generation rose rapidly in the vacuum separation tank, form foam oil.Foam oil is because density is low, thereby liquid level control switch is difficult for detecting true oil level, and the foam oil of rising is easy to be extracted out and produced fuel injection event by vavuum pump.
When 2, tank level control system broke down, the liquid level control in the vacuum separation tank was malfunctioning or oil-feed is malfunctioning, also the vavuum pump oil spout will take place.
The vavuum pump generation oil spout of vacuum oil-filter, heavy then damage vavuum pump, light contaminated environment and waste oily resource then.Therefore, avoiding vavuum pump generation oil spout, is one of important measures of guaranteeing vacuum oil-filter safety, reliability service.Application number is that 96208342.9 Chinese patent discloses " a kind of automatic control self check high-efficiency vacuum oil filter ", this patent disclosure one " labyrinth type foam automatic controller ", this labyrinth type foam automatic controller is made up of steam inlet pipe, exhaust tube, housing, Lv Droplets net, dividing plate, oil return pipe, the foam electronic sensor that disappears etc., and this labyrinth type foam automatic controller mainly has the following disadvantages:
1, complex structure is made comparatively difficulty.
2, its oil return pipe connects with vacuum separation tank, and foam or fluid very easily enter the right chamber of labyrinth type foam automatic controller from oil return pipe, and cause the vavuum pump oil spout.
3, the air inlet pipe of labyrinth type foam automatic controller is arranged on tank base, and its drawback is: if labyrinth type foam automatic controller is contained in position more than the vacuum separation tank top, just increase the volume of entire machine, and outward appearance is inharmonious.As being provided with and vacuum separation tank top almost parallel, then the left chamber of labyrinth type foam automatic controller and air inlet pipe are easily amassed oil and can't be got rid of.
Three, summary of the invention
The purpose of this utility model is the weak point at existing vacuum oil-filter, a kind of anti-vavuum pump fueling injection equipment of vacuum oil-filter is provided, it is simple in structure, easy to maintenance, can prevent the vavuum pump oil spout effectively, can prolong the service life of vavuum pump, guarantee the characteristics such as safe and reliable operation of vacuum oil-filter.
The purpose of this utility model is achieved in that a kind of anti-vavuum pump fueling injection equipment of vacuum oil-filter, be arranged on the vacuum separation tank and the exhaust tube between the vavuum pump of vacuum oil-filter, the utility model mainly comprises: housing, steel wire, inflation magnetic valve, liquid level sensor, draining valve etc., it is simple in structure.Be arranged on left side in the anti-vavuum pump fueling injection equipment housing with the tank connected exhaust tube of vacuum separation, and stretch into bottom at steel wire; The exhaust tube that is connected with vavuum pump is arranged on the right side of housing, and stretches into above steel wire; Steel wire is arranged in the interior big portion space of anti-vavuum pump fueling injection equipment housing, to gas and oil mixture or the foam type oil of extracting out from vacuum separation tank, the effect of separation oil and gas and elimination foam is arranged; Draining valve is arranged on the bottom of housing, so that the discharge of anti-vavuum pump fueling injection equipment oil, liquid level sensor is arranged on the middle part of anti-oil spout device case, and the upper end that reaches corresponding to steel wire above liquid level sensor is provided with the inflation magnetic valve.Vacuum oil-filter is in operation, when oil level in preventing the vavuum pump fueling injection equipment or foam oil level rise to liquid level sensor, liquid level sensor just sends signal, passes the signal to the electric-control system of vacuum oil-filter, the following equipment of complete machine electric control system controls by lead:
(1) vavuum pump is shut down.After vavuum pump shuts down, just stop vacuum separation tank and anti-vavuum pump fueling injection equipment housing are bled, thereby the blocking-up oil level continues to rise and enters vavuum pump
(2) open the inflation magnetic valve.After the inflation magnetic valve is opened, just charge into air in anti-vacuum fueling injection equipment housing, vacuum reduces rapidly, and the vacuum separation tank inner foam is eliminated.
(3) send signal by manually opening the draining valve of anti-vavuum pump fueling injection equipment, in time discharge oil wherein.After manually closing draining valve, restart vavuum pump, vacuum oil-filter resumes operation.
The utility model is in operation vacuum oil-filter after adopting technique scheme, can prevent the vavuum pump oil spout effectively, thereby protect the safety of vavuum pump, has prolonged the service life of vavuum pump, guarantees the safe and reliable operation of vacuum oil-filter.And that the utility model also has is simple in structure, reliable operation, characteristics such as easy and simple to handle, easy to maintenance.The utility model can be widely used in purification, the regeneration of various vacuum oil-filters to various iundustrial oils, is the device of desirable anti-vavuum pump oil spout.
