Description

Automated fluid is provided and gathering-device

The field of the present invention relates to is liquid granting and gathering-device and system, more specifically say, relate to a kind of apparatus and method, its uses Weighing mechanism to replace cubing to collect the used liquid of some and provides the new liq of equal number, collects used liquid or provide new liq not need to clean this device also can both finish safely and effectively after each the use no matter be at that time.

Device with other machinery, electronics must regularly replace when using various liquid.Said apparatus comprises automobile, common mechanical, changer etc., and liquid comprises lubricating grease, refrigerant fluid, iknsulating liquid and other.Current way is, be used when surpassing service life at liquid, with they with do not emanate and packing less mode from device, collect huge tube or jar in.Not only same class and liquid not of the same race mixes, and various liquid mixes so also as machine oil and driving fluid.For example by the supply of different makers have different viscosities and additive-treated oil machine oil all is collected in the public huge waste liquid tank usually, like this, even other liquid (as cooling system conditioner and driving fluid) are arranged away, that causes is still one and has different viscosities and additive-treated oil mixed liquor.And various liquid all collect in packing less mode, in fact are exactly to allow used liquid continue to be subjected to the pollution of foul, dust, water etc., moreover, also increase the possibility that new, old liquid overflows and cause fire.

The compound of different waste liquids pumps or directly is injected in waste liquid carrier's the tube from tube or huge jar then.But for the liquid such as the machine oil of part recirculation, these used liquid to be sent to the circulating device of a used liquid, and used there liquid is cleaned and circulates.For various oil-based fluid such as machine oil, recirculator is filtered it, evaporates volatile matter, then the product that obtains is sold to each different ultimate user, for example sells to the fuel use of carrier as the bunker fuel cabin.Compare with the better quality of the higher price of fresh oil, the value of this recaimed oil is lower.In addition, the prescription teacher of lubricating oil will not buy this recaimed oil because their physics and chemical nature are lack of consistency, and this point partly is owing to comprising the cause of different additive in the oil of different makers.The oil that bigger problem was to use in being collected into the also packing less container of not emanating the time regular meeting by the pollution of other oil-based fluid such as hydraulic oil, driving fluid and foul, dust, grease even water and cooling system conditioner.Common used liquid is collected in unlimited basin and the tube.So not only make pollutants enter in the used liquid easily but also can not prevent fire, and the slip on overflowing liquid, if used liquid is gone in the surrounding environment, can also cause disaster to surrounding environment.

Used liquid to collecting with art methods not only has purifying problem, and also has and be used for collecting waste liquid and provide container and the cleaning of equipment and the security-related problem of new liquid.For example, the fresh oil container be delivered to the scene and with its inclusion clearancen after, container or be dropped, or had the oil vessel of license to clean commercial steam and acid is cleaned by one, be used for packing fresh oil into then again or be issued to the public service station or other are on-the-spot so that be used for collecting used liquid or other used products.Cleaning new with these, old liquid container is relevant, and with the storage of these containers with provide relevantly, because they are neither pressure container can not bear serious impact, therefore needs sizable expense, and they also can bring deletrious impact to environment.

People once did many trials and wished to provide simple and the recovery and the delivery system of the used liquid of actv..As authorizing the No.4 of Culpepper etc., 109,831 in the US Patent; Authorize the No.2 of Gray, 477,450; Authorize the No.2 of Tabet, 552,749; Authorize Dunn etc. 2,536, No. 492; Authorize Koester 2,612, No. 289; Authorize Kitajima 3,430, No. 730; Authorize Bauer 4,378, No. 026; And 4,095, No. 672 of authorizing Senese all once made every effort to address the above problem, but all can't meet the demands.

Except these problems, also have a problem to be, how to measure the quantity of from the liquid operative installations, collecting and providing to the liquid of this device.Administer the personnel of liquid changing or know the correct volume (for example from service manual) of the new liq that need to add in advance, or do not know, need to measure the volume of collected used liquid, add the new liq of same quantity then.

Because exist a large amount of different automobiles, the personnel that administer liquid changing often must consult the volume that handbook is determined required liquid.But the volume of required liquid sometimes, as crankcase oil, in fact with handbook on listed different, this is owing to added oil cooler and/or other changes on automotive engine and cooling system.Another problem is sometimes that the quantity of the used liquid of taking-up will be lacked than the new liq of needs because liquid loses in device.

Usually join the correct volume of the new liq in the liquid operative installations or measure, or measure with volumetric displacement meter with a container (as the liter bottle) with known volume.But rate of volume flow is haggled over expensive, and if the user can not determine that this installs the correct volume of required liquid, so this metering is otiose.

Therefore need one effectively, safety, apparatus and method simple, reliable, environmental sound collects from automobile, the machinery that uses liquid and the used liquid that comes out installing, and change the new liq of same quantity, and can know the precise volumes of required new liq in advance.

An object of the present invention is to provide a device, it can be collected used liquid reliably and the new liq of same quantity is provided to the liquid operative installations.

Another object of the present invention is will provide a kind of device so that replace cubing to collect used liquid and provide the new liq of same quantity to the automobile that uses liquid, machinery or install with weighing.

Another object of the present invention is that a kind of liquid changing device will be provided, and it can provide used liquid and new liq is provided to this device from the liquid operative installations, and employed mode is automatically and can prevents to overflow unexpectedly.

Another object of the present invention is that a kind of liquid changing device will be provided, and it utilizes vacuum to take out used liquid and utilizes the unreactable gas of compression to provide new liq.

It is that a low expense system with the environmentally safe of portable part (second one) and fixed part (first one) and cleaning will be provided that a purpose is arranged again.This system allows the recovery of used liquid and the granting of new liq directly to carry out in the portable part on the scene of automobile, mechanism or device, and with the used liquid of the turned letter of portable part and replenish new liq and be placed in the fixed part and carry out.So not only can be significantly or fully eliminate the cleaning of new liq tube or other new liq containers, but and can collect the used liquid stream of more recirculation, this liquid stream has more consistent physical/chemical value, and will be more valuable to the teacher that fills a prescription.Adopt another advantage of this system that to have two parts be portable part and fixed part to be, it can make the mode of new, old liquid at high speed, cleaning and safety change.Portable part preferably adopts above-mentioned weighting apparatus.

Consult Fig. 1-3 now, first embodiment of collection of automated fluid shown in it and dispensing apparatus 10 can be used to collect used liquid and also new liquid is provided to the liquid operative installations.Device 10 comprises storage tank row 12, and the storage tank or the container 16 that wherein have a storage tank that used liquid or container 14 to be used for collecting and store a used liquid and a new liq are used for storing and providing new liquid.Used and new wet tank 14 and 16 is the leak free pressure vessel.These storage tanks preferably have witness marking such as bar code sign and/or color-bar 17 as a means of the material of distinguishing in it, as the heavy shell machine oil of new 10-40, with the heavy shell machine oil of 10-40, new anti-freezer, with anti-freezer etc.Used the storage tank 14 of liquid can be under the vacuum that power is good to move to used liquid in the storage tank 14 that used liquid from liquid operative installations such as automobile as a means of providing.The new storage tank 14 and 16 with used liquid is preferably the pressure container of US Department of Transportation (D.O.T.) approval, and magnitude range is 20 to 30 gallons easily.

Storage tank row 12 are installed on the dolly 18.This dolly 18 has a storage tank back plate 20, and its upper surface is 22, and lower surface is 24.Storage tank row 12 are shelved on the upper surface 22.Weight sensing device such as load transducer 26 are positioned on the dolly 18, extension below lower surface 24.Preferably use 26, two of three load transducers in the back 27, one preceding 29, no matter like this ground surface G injustice how, the total weight of storage tank row 12 and interior material thereof will be carried by load transducer 26.This dolly 18 has two pairs of wheels 28 and 30 carrying wheel support spare 32.Wheel support spare 32 extends with storage tank bearing 34 oblique back.Handle 36 preferably extends back from the back of dolly 18.

Under the mobile status of Fig. 1, the storage tank bearing 34 of dolly 18 recedes, so dolly 18 rests on the ground G, and weight is by wheel 28 and 30 carryings.For dolly 18 can be turned to better, wheel 30 preferably can rotate.Under mobile status, storage tank row 12 rest on the storage tank bearing 34, and load transducer 26 does not contact with ground G.Consult Fig. 2, under the state of weighing, the weight of dolly 18 and storage tank row 12 and interior material thereof is carried and is not carried on wheel 28 and 30 by load transducer 26 fully.Load transducer 26 be used to determine said storage tank row 12 and any involved use within it liquid and new liq on weight, whether change.Telltale 38 as digital reader can illustrate data such as the weight from load transducer 26.In addition, telltale 38 if fluid density is known, can be transformed into volume (as liter) with the weight (as kilogram) that records.Because the measurement of load transducer 26, when using liquid to be extracted to use in the liquid tank 14, the numeral of telltale 38 can increase, and when new liq was in new liq storage tank 16 is be delivered to the liquid operative installations, the numeral of telltale can descend.When the reading on the telltale 38 reaches zero, the user just know some use liquid substituted by the new liq of equal number.

Consult Fig. 3, used liquid valve 40 to be connected to and used on the liquid tank 14, also have a new liq firing level 47 to be connected on the new liq jar 16.Used liquid valve 40 to have a pipe 41 to extend downwardly near using the bottom of liquid tank 14 so as to use liquid in it by using liquid valve 40 to be sucked out.Also being provided with second valve 43 of bringing mouth 39 into will use liquid container 14 to place under the vacuum so that be used for.There is a short tube 45 to stretch into one little section to using in the liquid container 14 and being used to and using liquid container 14 to place under the vacuum.Use liquid tank 14 to be essentially the scene that the state that vacuumizes is transported to automobile, therefore used liquid to be extracted in it soon.The short tube 44 that has a nitrogen to charge into valve 42 extend in the new liq jar 16 one little section.One import 49 is arranged on new liq firing level 47 and have a feed pipe 51 to extend downwardly into bottom near new liq jar 16.New liq jar 16 is filled with the band unreactable gas of pressure such as nitrogen and with the pressurization of the new liqs in the new liq container 16 and by feed pipe 49 and new liq firing level 47 new liq is displaced.Because new liq is to leave storage tank 16 in the bottom near storage tank 16 by feed pipe 49, the nitrogen quantity of staying when the new liq in the container 16 is discharged in the new liq jar 16 can be constant substantially, unless certainly the horizontal surface of the new liq in container 16 drops under the horizontal surface of import 53 of feed pipe 51, and this is under normal circumstances impossible.Stretch because the reduction of new liq horizontal surface in new liq jar 16, cause the pressure of unreactable gas and speed that new liq can be issued all can reduce.These characteristics will remind that the operator is that this is when being added to new liq in the new liq jar again.

Consult Fig. 4-6 now, shown device 10 is used to carry out the replacing of automotive engine 44 inner fluids.The use that has an end 48 that used liquid sebific duct 46 to be connected to use liquid tank 14 on the liquid valve 40, its other end 50 is placed to oil dip rod opening 52 interior and following the arriving in the catcher groove 54 of driving engine of driving engine 55, contacts with the used machine oil that contains within it.Telltale 38 can be reset to zero by pressing on/off on-off switch 60.Consult Fig. 4, telltale 38 is drawn out of in the catcher groove 54 of driving engine used oily 56 just, by using liquid line 46, using liquid valve 40 and entered into and be set to zero before using in the liquid tank 14.Used liquid tank 14 can be placed under the vacuum, as the vacuum of 50cm mercury column.Consult Fig. 5, used oil from catcher groove 54 removed after, just can will use liquid line 46 to pull out.Telltale 38 shows the readings (as 3.25) of an increase now, this reading point out since collect used oily 56 be stored in now and used the interior weight that makes the increase that load transducer 26 bears of liquid tank 14.Consult Fig. 6 now, an end 66 of a new liq sebific duct 64 is connected on the new liq firing level 47 of new liq jar 16.And its second end 68 can be placed in the pouring orifice 70 of driving engine 44.The unreactable gas of pressurization such as nitrogen, carbon dioxide, helium or other can provide power that fresh oil 72 is shifted out in new liq jar 16, by new liq firing level 47, with new liq sebific duct 64, enter in the driving engine 44 of automobile, enter into catcher groove 54 then backward.The employing unreactable gas helps anti-oxidation and new liq is stored in existing any potential fire hazard under the pressure.Greatly about 7.0 to 8.5kg/cm ²(100 to 120 pounds/sq in) just can work effectively, though other pressure also can work.

When collecting waste liq by the waste liq pipe, can the oil dip rod opening 52 of waste liq pipe by automobile do not inserted as shown in Figure 4, but on waste liq pipe 46, be equipped with a new annex 53, again this annex liquid thickly is bonded on the accessory 59 of the rapid release on the food tray 57 of a catcher groove 54 that is fixed on serviced automobile, shown in Fig. 4 b.

Along with the use of constant weight is crossed oil and 56 is removed, inserted etc. the fresh oil 72 of weight, the reading of telltale 38 descends and turns back to zero, points out the weight that the granting owing to fresh oil 72 disappears.If the user wishes used oily 56 to add more fresh oils 72 (determining that the horizontal surface of machine oil is lower when for example checking with oil dip rod) than what take away, the user can continue to add fresh oil 72 and makes the telltale reading drop to subzero (not shown) so.

Consult Fig. 7 now, shown device 10 is used to get rid of used radiator liquid 80 from the radiator 82 of automobile by its blowoff valve 84.Have the use using liquid sebific duct 86 to be connected to blowoff valve 84 and used liquid tank 14 on the liquid valve 40.Again, telltale 58 was set to zero before beginning to collect used radiator liquid 80, but along with using being drawn into of radiator liquid 80 to use in the liquid tank 14, the reading of telltale 58 will rise.Device 10 shown in Fig. 8 is used to replenish radiator 82 with new radiator liquid 88.There is a new liq sebific duct 90 to be connected on the new liq valve 42 of new flow container 16.Along with being collected of used radiator liquid 80, be issued etc. the new radiator liquid 88 of weight, the reading of telltale 58 can not descend and turn back to zero.

Though said apparatus 10 is used to change the machine oil and the radiator liquid of automobile, it also can be used to change any amount of liquid.For the purity of the liquid of keeping various used liquid of collecting and various new granting, storage tank row 12 best designated collections and provide the liquid of some appointment such as machine oil, radiator liquid and other liquid of specific grade and brand.The used liquid of collecting will pool together and be delivered to a recirculator of using liquid with identical used liquid.Because native system helps to prevent that different used liquid is mixed in together, the value of the used liquid of collecting is with much higher, because it can be become the product of high value by remanufacturing.In addition, because each used liquid to be used to store a kind of specific liquid respectively and only stored this kind liquid, so just no longer need the storage tank row 12 of washing equipment 10.

In order to make this device can be automatic more completely, used liquid valve 40 and new liq valve 42 to control with telltale 58, make when all used liquid have all been extracted out in using liquid container 14 when vacuum detector 62 detects the vacuum of using in the liquid tank and disappeared, used liquid valve 40 to close.Perhaps, in a schedule time, no longer can when load transducer 26 detects changes in weight (pointing out that all used liquid all are collected), can close when telltale 58 using liquid valve 40 to be set at.Equally, new liq valve available display 58 is controlled, and when telltale 58 reappears zero, just knows with the use of collecting that the identical new liq of weight of liquid was issued.
