Background technology
Oil conditioner also known as oil filter, vacuum oil purifier are a big class in oil conditioner.The reactor of vacuum oil purifier is
The significant components of vacuum oil purifier, the reactor of vacuum oil purifier have heating oil, oil in reserve, dehydration, degassing, mixing filter aid
Deng effect.For a long time, when adding filter aid into the reactor of vacuum oil purifier, needs are uncapped from the top of reactor tank body
It is artificial to add filter aid.Later, this utility model Crinis Carbonisatus understood the oil conditioner reactor of addition filter aid automatically, Patent No. ZL
2012 2 0295131.3, patent application day is on June 21st, 2012, and the technical scheme is successfully realized the effect in vacuum
Under, add automatically filter aid to the reactor of oil conditioner, in the technical scheme, due to the position of filter aid hopper it is relatively low, when
When the sump oil liquid level of reactor is higher, and the vacuum in reactor it is relatively low when, or during misoperation, it may appear that sump oil is from anti-
Answer kettle to blow back into the phenomenon in filter aid hopper, not only there is serious potential safety hazard, and just have a strong impact on the oil conditioner
Often work, for this purpose, the oil conditioner reactor of the existing automatic addition filter aid that has much room for improvement, prevents the dirt in oil conditioner reactor
Oil is blowed back in filter aid hopper.
The content of the invention
The purpose of this utility model:The vacuum oil purifier retort that a kind of oil does not flow backwards filter aid case is provided.
The technical solution of the utility model is:A kind of oil does not flow backwards the vacuum oil purifier retort of filter aid case, its feature
Be that tank body is hermetically sealed can, inlet valve is externally connected with tank body, be connected with air outlet valve, vacuum pumping valve, in tank at the top of tank body
The side wall of body is provided with liquid level control switch, manhole, liquidometer, is provided with retort heater in the bottom of the inside of tank body,
The bottom of tank body is connected with residual cake valve, delivery valve, compressed air air entraining valve, is externally provided with filter aid hopper, plus filter aid in tank body
Pipe one end is located at the lower of filter aid hopper, plus the other end of filter aid pipe passes through the case lid of filter aid hopper from the top of tank body
Into the bottom in tank body, be provided with filter aid pipe is added plus filter aid valve, filter aid hopper be provided with filter aid hopper and added
Hot device.
Described oil does not flow backwards the vacuum oil purifier retort of filter aid case, is additionally provided with vacuum tube and dissipates in filter aid hopper
Hot device, described vacuum tube radiator are exactly the vacuum tube of one end spiral plate-like, the vacuum tube of spiral plate-like and the oil vacuum cleaning
The vacuum tube of the vacuum pump of machine is communicated.
Oil described above does not flow backwards the vacuum oil purifier retort of filter aid case, the oil inlet pipe of the inlet valve described in which from
The bottom of tank body enters the top inner wall for arriving tank body again, is provided with oil-feed kuppe, on the top of tank body at the oil-out of oil inlet pipe
Portion is provided with observation window.
Filter aid:It is, in filter operation, in order to reduce filtration resistance, to increase filtering rate or obtain the filter of height clarification
Powdery or particulate matter that liquid is added, conventional filter aid have kieselguhr, perlite, cellulose, asbestos, graphite powder, sawdust,
Magnesium oxide, Gypsum Fibrosum, activated carbon, Emathlite etc..The filter aid that oil conditioner retort is added is preferred using powdery.
Oil-feed of the present utility model:When needing for sump oil to add the tank body of retort, inlet valve, vacuum pumping valve are opened,
Close other valves, sump oil is by negative pressure suction tank body, and the sump oil amount of suction is observed by liquidometer, closes inlet valve, takes out true
Empty valve just stops oil-feed.Sump oil can also be pumped in the tank body of retort using oil pump.
Automatic addition filter aid of the present utility model:When needing to add filter aid, the filter aid of appropriate powdery is stored
In filter aid hopper, tank body enters appropriate sump oil, opens charging valve, vacuum pumping valve, closes other valves, and negative pressure is by filter aid
It is drawn in tank body, after completing to add filter aid, closes charging valve, vacuum pumping valve;The filter aid that this utility model is used is work
Property hargil dry powder and perlite dry powder mixed powder, the mesh number of mixed powder is 100-300 mesh, and the gross weight of mixed powder is less than sump oil
The 1-10% of gross weight.It is to enter filter aid, retort from a high position at the top of the tank body of retort due to adding filter aid pipe in this utility model
Tank body in sump oil cannot flow backwards out.
Automatic stirring of the present utility model:When needing to be stirred the sump oil and filter aid in tank body, open into pressure
Contracting air cock, air outlet valve, make compressed air enter from the bottom of tank body, discharge from air outlet valve, under vacuum work state, also may be used
Remove from vacuum tube chain.After stirring terminates, close into compressed air valve.
Heating of the present utility model:When needing to heat the filter aid in filter aid hopper, drainage is directly initiated
In agent hopper, filter aid hopper heater is completed;When the sump oil in the tank body needed to retort is heated, directly initiate
Retort heater in the tank body of retort is completed, when the sump oil amount in the tank body of retort is less than liquid level control sensor
During control height, there is protective effect in liquid level control switch, make retort heater stop heating.
Fuel-displaced filtration of the present utility model:When the sump oil in the tank body of reactor carried out degassing, dehydration, plus filter aid,
After heating, flocculation etc., need sump oil in the tank body by reactor to discharge when filtering, open delivery valve, air cock, oil pump with go out
Fuel tap connects, in the presence of oil pump, after the sump oil in the tank body of reactor is extracted from delivery valve, into the filtration of lower operation
Process.
Residual cake valve of the present utility model is sunken to the dregs of fat of the bottom of the tank body of reactor for exclusion, or in cleaning reaction
The deslagging during tank body of kettle;Manhole is used to overhaul retort heater, liquid level control sensor etc.;Observation window is used for observing response
Situation in the tank body of kettle;At the top of the tank body of reactor, relief valve can also be set.
The beneficial effects of the utility model:Oil of the present utility model does not flow backwards the vacuum oil purifier retort of filter aid case,
The reactor for not only realizing the oil conditioner of vacuum oil purifier picks up from dynamic addition filter aid, and, automatic addition filter aid safety,
Reliable, sump oil is not flow backwards into filter aid hopper from reactor, eliminates serious potential safety hazard, with promotional value.
