Description

AUTOMATIC FLUID DISPENSING AND COLLECTING DEVICE}

Mechanical, electrical, and other devices use a variety of liquids that must be replaced periodically. Such devices include automobiles, machinery, transformers, and the like, and the liquids include lubricants and greases, cooling liquids, insulating liquids and other types of liquids. In the practice of the present invention, after the liquids have been used beyond their useful life, the liquids are collected from the apparatus into the bulk drum or tank in an unseparated and unsealed manner. Different kinds of the same class of liquids are mixed and various different liquids, ie automobile oil and transmission oil, are mixed together in this way. For example, different viscosity and mixture packaging motor oils are typically collected in a common bulk used liquid tank by different manufacturers, and even different liquids (i.e. coolant and transmission liquid) are kept mixed to intersect different viscosity and additives. The mixture is mixed. The fact that the various liquids are collected in an unsealed way causes the used liquid to become more contaminated with dirt, dust, water, etc., increasing the likelihood of spillage of new and used liquids and the risk of fire.

The mixture of different used liquids is then popped out of the drum or bulk tank, or stored directly in the drum by the used liquid collector. In the case of partially renewable liquids, such as automotive oils, these used liquids are delivered to used liquid reclaimers that can purify and recycle used liquids. In the case of various oil based liquids, such as automotive oils, the reclaimer filters this liquid, breaks off the volatiles, and sells the resulting product to the shipper for use as a variety of end users, for example as ship bunker fuel. do. In contrast to new lubricant oil raw materials of relatively high price and high quality, the value of such recycled oil is cheap. Moreover, the lubricating oil prescriber does not purchase such reclaimed oils, in part because of their inconsistent physical and chemical properties due to the different oil additive containers contained in the oil of other manufacturers. A more serious problem is that while other oil based liquids, such as hydraulic liquids and transmission liquids, are often contaminated with contaminants, dust, grease and even water and coolants, while the used oil is collected in an unseparated and sealed container. Often used liquid is collected in open kinematics and drums. This not only allows other contaminants to enter the used liquid, but also protects against fire hazards, slippage by spilled liquids and environmental hazards that occur when the used liquid is exposed to the environment.

The resulting used liquid collected by the prior art methods suffers from purity issues as well as issues related to cleaning and safety of the containers and utensils used to collect and dispense new liquid. For example, after a new lubricant container is dispensed to a certain location and its contents empty, the container is discarded, or steam and acid are cleaned by a licensed oil container cleaner, then reused or collected with new oil. Dispensed to service stations or other locations for use in liquids or other used products. There are substantial costs and toxic environmental impacts associated with cleaning new and used liquid containers, as well as storing and dispensing such pressure containers or those containers that are not able to withstand severe impacts.

Many attempts have been made to more efficiently provide the used liquid recovery and distribution system. Attempts to solve the above problems include U.S. Pat. U.S. Patent No. 2,536,492 to Dunn et al., U.S. Patent No. 2,612,289 to Koester, U.S. Patent No. 3,430,730 to Kitajima, U.S. Patent No. 4,378,026 to Bauer, and Senes (Senese) US Patent No. 4,095,672, but all of these failed.

In addition to these problems, there is also a problem of how to measure the amount of liquid collected from and dispensed from the liquid using device. The person performing the liquid exchange knows in advance the exact volume of new liquid required (ie from the service manual) or measures the volume of collected used liquid and replenishes a similar amount of fresh liquid.

Due to the large number of different cars, the person performing the liquid exchange should consult the manual often to determine the volume of liquid required. However, sometimes the required volume of liquid, ie crankcase oil, is actually different from what is listed in the manual by adding oil coolant and / or other exchange fluids to automobiles and cooling systems. Another problem is that the loss of liquid into the device frequently occurs, so that the amount of used liquid removed may be less than the amount of fresh liquid required.

The correct volume of fresh liquid is replenished to the liquid utilization device by replenishing fresh liquid from a container having a known volume (i.e., a liter bottle of fresh liquid), or by using a volumetric flowmeter. Volumetric flowmeters are relatively expensive and will rarely be metered if the user does not know the exact volume of liquid required for the device.

Thus, an efficient, safe, simple, reliable and environmentally harmless device, the same amount of new liquid without knowing the precise volume of new liquid required and how to collect used liquids from liquid vehicles, machinery and devices. There is a need for a method for replacing used liquids.

Summary of the Invention

1 to 3, there is shown a first embodiment of an automatic liquid collection and dispensing apparatus 10 for collecting used liquid and dispensing fresh liquid to the liquid utilization device. Apparatus 10 includes a tank apparatus 12 having a used liquid tank or vessel 14 for collecting and storing used liquid and a new liquid tank or vessel 16 for storing and dispensing new liquid. . Used and fresh liquid tanks 14, 16 include sealed pressure tanks. Preferably, this tank has its contents, i.e. fresh 10-40 wt. Shell motor oil, used 10-40 wt. Visual indications such as bar code stamps and / or color strips 17 are provided to identify Shell motor oil, fresh antifreeze, used antifreeze, and the like. The used liquid tank 14 is positioned under vacuum to provide power and is suitable for moving the used liquid into the used liquid tank 14 from a liquid utilization device such as an automobile. New and used liquid tanks (14, 16) range in size from 20 to 30 gallons. It is preferably a pressure vessel certified by the Department of Transportation (D.O.T.).

The tank device 12 is conveyed to the cart 18. The cart 18 has a tank support plate 20 having an upper surface 22 and a lower surface 24. The tank device 12 is located on the upper surface 22. Weight sensing means, such as load cell 26, is located on cart 18 and extends below bottom surface 24. Three load cells 26, i.e. two rear load cells 27 and a front load cell 29, are used so that the total weight of the tank device 12 and its contents is independent of the non-uniform ground plane G. It is desirable to be able to be supported on the load cell 26. The cart 18 has a pair of wheels 28, 30 supported on the wheel support member 32. The wheel support member 32 is inclined rearward from the tank cradle 34.

In the driving mode of FIG. 1, the cart 18 is tilted rearward, such that the cart 18 is located on the ground G supported on the wheels 28, 30. The wheel 30 is preferably rotatable to better adjust the cart 18. In the travel mode, the tank device 12 is positioned against the tank cradle 34 and the load cell 26 is not in contact with the ground G. With reference to FIG. 2, the weight of the cart 18 and tank arrangement 12 and their contents are entirely supported on the load cell 26 and not on the wheels 28, 30. The load cell 26 is used to determine all the weight changes of the tank apparatus 22 and all used liquid and fresh liquid retained therein. Display means 38, such as a digital read, determines the data from the load cell 26 by weight. In addition, the display means 38 can convert the weight measurements (eg kilograms) into volumetric measurements (eg liters) if the density of the liquid is known. The display means 38 is increased when the used liquid is drawn into the used liquid tank 14 when measured by the load cell 26 and the new liquid tank 16 when new liquid is measured by the load cell 26. Decreases from) to the liquid utilization device. When zero reading is made on the display means 38, the user can see that a certain amount of used liquid has been replaced by an equal amount of new liquid.

Referring to FIG. 3, the used liquid valve 40 is connected to the used liquid tank 14, and the new liquid dispensing valve 47 is connected to the new liquid tank 16. The used liquid valve 40 has a pipe 41 extending downward to near the bottom of the used liquid tank 14 to allow the used liquid to be sucked from the used liquid valve 40 and used liquid valve 40. To get through. In addition, a second valve 43 with an inlet 39 is provided for applying a vacuum on the used liquid container 14. It includes a short stub pipe 45, which extends in a short path into the used liquid tank 14 and applies a vacuum to the used liquid tank 14. The used liquid tank 14 is dispensed into the position of the vehicle in a substantially evacuated vacuum state so that the used liquid can be sucked into it quickly. Nitrogen fill valve 42 includes a short stub pipe 44 that extends briefly into a fresh liquid tank 16. The new liquid dispensing valve 47 has an inlet 49 and a supply pipe 51 extending downwards near the bottom of the new liquid tank 16. The new liquid tank 16 carries a pressurized inert gas such as nitrogen, which pressurizes the new liquid in the new liquid tank 16, which feeds the liquid into the supply pipe 49 and the new liquid dispensing valve 47. Emit through. Since fresh liquid exits the tank 16 through the supply pipe 49 near the bottom of the tank 16, a large amount of nitrogen gas is depleted when the new liquid in the tank 16 is depleted. Remains substantially unchanged in the tank, nevertheless the level of fresh liquid in the tank 16 falls below the level of the inlet 53 of the feed pipe 51. However, this usually does not occur because the level of new liquid in the new liquid tank 16 drops, so that the inert gas pressure and the rate at which the new liquid is dispensed are also lowered. This feature reminds the operator that it is time to refill the new liquid tank 16 with new liquid.

4 to 6, the device 10 is shown to be used to change the oil of an automobile motor 44. One end 48 of the used liquid hose 46 is connected to the used liquid valve 40 on the used liquid tank 14. The other end 50 is located below and within the automotive oil sump 54 which is in contact with the used automotive oil 56 retained therein and in the retaining rod opening 52 of the automobile 55. The display device 38 can be reset to zero by operating the on / off switch 60. Referring to FIG. 4, the display device 38 immediately exits the automotive oil sump 54 into the used liquid tank 14 through the used liquid tube 46 and the used liquid valve 40 by the used oil 56. Before it is set to zero. The used liquid tank 14 is suitable for being placed in a vacuum, such as a 50 centimeter mercury vacuum. Referring to FIG. 5, the used liquid tube 46 is removed after the used oil 56 is removed from the oil sump 54. The display means 38 is an incremental reading (e.g. 3.25) indicating the increased weight obtained by being supported on the load cell 26 as a direct result of the weight of the collected used oil 56 stored in the used liquid tank 14 Is displayed. Referring to FIG. 6, one end 66 of the new liquid hose 64 is connected to a new liquid dispensing valve 47 on the new liquid tank 16 and located at the oil filling port 70 of the automobile 44. It has a second end 68 suitable for. Pressurized inert gas such as nitrogen, carbon dioxide, helium, etc., to power the new oil 72 leaves the new liquid tank 15 through the new liquid dispensing valve 47 and through the new liquid hose 64 through the vehicle 44. And into oil sump 54 again. By using an inert gas it oxidizes during storage of fresh liquid under pressure and prevents any potential fire hazards. Nitrogen at about 7.0㎏ / ㎠ to 8.5㎏ / ㎠ (100lbs / in ² to about 120lbs / in ²⁾ will effectively act as another, even if applied pressure.

Instead of collecting the waste liquid through the waste liquid tube inserted through the car door rod opening 52 as shown in FIG. 4, the waste liquid tube 46 is used to supply the oil of the vehicle to be serviced as shown in FIG. 4A. It can be fitted with a new attachment 53 which engages with a liquid seal with a quick disconnect fitting 59 fixed on the oil pan 57 of the sump 54.

After dispensing fresh oil 72 of the same weight as the removed used oil 56, the display means 38 is reduced back to zero indicating loss of weight due to the dispensing of fresh oil 72. If the user wants to fill new oil 72 more than the amount of oil 56 removed (for example, when the car oil level is lower than determined by inspecting the core rod), the user reduces the display means to below zero. Continue to replenish additional fresh oil 72 until it is shown (not shown).

Referring to FIG. 7, the device 10 is shown to be used to remove a used radiator liquid 80 from an automobile radiator 82 through an automobile exhaust valve 84. The used liquid hose 86 is connected to the discharge valve 84 and the used liquid valve 40 of the used liquid tank 14. Again, the display means 58 goes to zero before collecting the used radiator liquid 80 but is incremented upwards as the used radiator liquid 80 is sucked into the used liquid tank 14. FIG. 8 shows the apparatus 10 used to replenish the radiator 82 with fresh radiator liquid 88. The new liquid hose 90 is connected to a new liquid valve 42 of the new liquid tank 16. The display means 58 will be reduced back to zero again when a new radiator liquid 88 of the same weight as the collected used radiator liquid 80 is dispensed.

Although the apparatus 10 has been described above with reference to exchanging automotive oil and radiator liquids, the apparatus 10 may be used to exchange all many liquids. In order to maintain the purity of the various used liquids collected and the new liquids dispensed, the tank apparatus 12 is designed to collect and dispense certain designated liquids, namely automotive grades, radiator liquids, transformer liquids and other liquids of certain grades and brands. It is desirable to be. The collected used liquid is collected together with the same used liquid and distributed to the used liquid regenerator. Since the present system prevents different used liquids from mixing together, the value of used liquid collection is higher because the high value product can be reprocessed again. Moreover, since each used liquid container can be used to store only one particular liquid and this liquid, there is no need to clean the tank device 12 of the device 10.

In order to achieve more complete automation of the device, the used liquid valve 40 and the new liquid valve 42 can be controlled by the display means 58, so that the used liquid valve 40 has a vacuum detector 62 If it detects that it has been lost in the used liquid tank, it shuts off and signals that all used liquid has exited the used liquid tank 14. As a variant, the used liquid valve 40 may be set to shut off if the display means 58 stops detecting weight change for a predetermined time from the load cell 26 (when all used liquids have been collected). ). Similarly, the new liquid valve may be controlled by the display means 58 after the display is zero, indicating that a new liquid of the same weight as the collected used liquid has been dispensed.

9-12 show a variation of the automatic liquid collection and dispensing apparatus 100. In this arrangement, the used liquid tank 102 and the fresh liquid tank 104 are suspended from the weight scale 106. The used liquid valve 108 and the new liquid valve 110 are fitted to their respective use and new liquid tanks 102 and 104. The weight scale 106 is suspended from the retaining bracket 112 on the cart 114. The specific and all total weight changes occurring in the suspension tank, such as the liquid collected in the used liquid tank 102 and dispensed from the new liquid tank 104, are displayed by the weight scale 106. In this way, in order to use the system the weight scale is zeroed before use. After the specific weight of used liquid is collected in the used liquid tank 102 and the scale 106 shows the specific weight, the new liquid indicates that the same amount of new liquid as the collected used liquid has been dispensed and the weight scale is zero. May be dispensed from fresh liquid tank 104 until returned to.

10-12, one embodiment of the support bracket 112 is shown, with the scale 106 and its suspension tanks 102, 104 being shown in FIG. 10 in the travel mode (tanks 102, 104). Weight of the cart 114 is at least partially supported on the base 116 of the cart 114 so that the weight of the scale 106 is not applied) and the metering mode shown in FIG. 11 (tanks 102 and 104 and their contents). The weight is easily measured between the scales 106. In one simplified embodiment, the support bracket 112 includes a bracket tube portion 117 having a longitudinal slot 118 formed on its side. The bracket tube portion 117 is attached near the top of the cart 114. The slide 120 is sized to slide fit into the bracket tube portion 117 and has a pivot slider 122 at the distal end closer to the cart 114. Scale suspension ring 124 is located at the proximal end of the sliding portion, and scale 106 is suspended therefrom. 10 and 12, the slide portion 120 is pulled forward, mostly out of the bracket tube portion 117, such that the slide portion 120 is suspended downward so that the scale 106 and the tanks 102, 104 are oriented. Of weight is supported on the base 116 of the cart 114. Referring to FIG. 11, in the metering mode the sliding portion 120 is raised to a horizontal position and pushed into the bracket tube 117 so that the total weight of the tanks 102, 104 and their contents are detected by the scale. Of course, other devices may be used to raise and lower the tanks 102 and 104 to switch the system to a run mode and a weighing mode.

With reference to FIG. 13, after one or more liquid exchanges have been made in the position of the vehicle or machine, the device 10 can be slid back to the position of the optional fixed first system 120 and positioned at any desired location. Can be. The first system 120 includes a series of dedicated sealed used liquid containers 122 (only one of which is shown) for collecting the particular used liquid 124 from the used liquid tank 14, and the specific new liquid 128. It consists of a series of new liquid tanks 126 (only one of which is shown) to receive the water. The volume of the fixed used and fresh liquid tanks 122, 126 is substantially larger than the second used and fresh liquid tanks 14, 16, ie, in the range of 175 gallons to 250 gallons. The fixed used liquid tank 122 is connected to a vacuum source 130 such as a vacuum pump or a venturi which issues a vacuum via the vacuum line 132. Ideally, the pressure sensor 134 feeds back to the vacuum state in the first used liquid tank 122, thereby controlling the application of the vacuum from the vacuum source 130, whereby the first used liquid tank 122 is located in the first used liquid tank 122. Maintain a relatively constant vacuum. The first used liquid tank 122 has a used liquid inlet valve 136 in which a short stub pipe 138 extends into the fixed used liquid tank 122 and an inlet 140 connected to the first used liquid suction hose 142. ). The termination 144 of the used liquid hose 142 is suitable for hermetic attachment to the outlet 39 on the empty valve 43 of the used liquid tank 14. When the used liquid inlet valve 136 is opened, the vacuum in the upper space of the fixed used liquid tank 122 is thus transferred from the used used liquid tank 14 via its second used liquid supply tube 45. Vacuum. When the used liquid is removed from the mobile used liquid tank 14, the vacuum pressure in the mobile used liquid tank 14 becomes lower than the vacuum pressure of the fixed used liquid container 122, and the second used liquid tank 14 Or to receive additional used liquid at the location of the machine.

Fixed fresh liquid container 126 has a constant source of supplying inert gas to the container at a predetermined pressure. We maintain a pressure regulator piped to the new liquid tank 126 via pipe 150 to maintain a constant inert gas pressure in the fixed fresh liquid tank 126 regardless of the volume of fresh liquid 128 retained therein. It has been found that the nitrogen gas cylinder 146 with 148 is convenient and inexpensive. For example, a nitrogen gas pressure of 7.0 kg / cm 2 to 8.5 kg / cm 2 (100 lbs / in ² to 120 lbs / in ² ) is provided with a sufficient pressure so that the new liquid tank 126 fixed while refilling the liquid as described below. ) Fresh liquid 128 can be quickly transferred from the new liquid tank 16 to the movable fresh liquid tank 16. A new liquid outlet valve 152 is provided on a stationary new liquid container 126. The new liquid outlet valve 152 has a fixed new liquid supply tube 154, the open end of which extends near the bottom of the fixed fresh liquid tank 126. The first end 156 of the fixed fresh liquid supply hose 154 is connected to the valve 152 and has a coupler 158 at its free end, which coupler 158 is a valve of the movable fresh liquid tank 16. It is suitable for liquid-tight coupling with the inlet 51 on 47. When the movable fresh liquid tank 16 returns to the position of the stationary portion 120 of the system, the tank 16 remains filled with a predetermined amount of nitrogen gas, but at a lower pressure than the gas in the fixed fresh liquid tank 126. Is maintained. Due to the nitrogen gas pressure difference, the nitrogen gas is moved from the fixed new liquid tank 126 to the movable new liquid tank 16 until the gas pressure in the movable new liquid tank 16 becomes equal to the pressure in the fixed new liquid tank 66. Will continue to push). This feature will automatically load the desired amount of fresh liquid into the second new liquid tank 16 without the need to monitor it by accompaniment.

In order to provide special safety, the first used and new liquid tanks 122, 126 are preferably located in the safety tube 160, the safety tube 160 having an interior larger than the internal volume of the containers 122, 126. It has a volume and can therefore be useful for capturing the contents of used or new liquid tanks 122, 126 in the event of a leak.

When the fixed used liquid container 122 is full, the used liquid is evacuated from the container 122 via the first used liquid container supply tube 162 and the valve 164 via a hose (not shown), The used liquid carrier connects his truck to the hose and removes it back into a dedicated container to maintain separation of the particular used liquid stream. Next, the specific used liquid is transferred to the reclaimer in a conventional manner. In the case of depleted fixed fresh liquid tanks 126, they are discharged via fresh liquid outlet valves 152 or alternatively redrawn through individual openings (not shown).

Although only a pair of used liquid first and second containers and new liquid first and second containers are shown, any number of used and new liquid first and second containers can be provided to accommodate the needs of a car or machine user. have.
