Abstract

A device for working with liquids in a metered fashion is described, said device not requiring an electrically driven pump. In a preferred exemplary embodiment, a cleaning liquid situated in a container underneath the working plane is employed. Arranged above a working basin forming the working plane is a storage container which, for filling, can be pivoted from the upright working position to a filling position below the level of the cleaning liquid in the container. After the storage container has been filled in this way, it is pivoted back to the working position. Leading from the point of the storage container which is lowest in this position is a delivery line which conveys the liquid out of the storage container into the cleaning tool, preferably a brush. The component to be cleaned is put into the working basin and cleaned using the brush. The cleaning liquid flowing away passes through a return line back to the first container.

Description

Device for working with liquids

The invention relates to a device for working with liquids as explained in the preamble of claim 1 Art.

From DE-PS 24 49 056 such a cleaning is already Known device used by components, in which the suction line is connected to the suction side of a pump and the discharge line is connected to its pressure side. At the start of work the pump is activated and pumps the cleaning liquid out of the container through the suction and the discharge line into the cleaning tool connected to the discharge line, which is either a brush or can be a brush or the like. Although this device has proven itself, it can only be used there where there is an electrical connection for the pump, which severely restricts its mobility, also is the Pump expensive.

The invention is therefore based on the object of designing a device of the type mentioned so that it can be electrically operated without an operated pump can work.

"f

The object is achieved by the features specified in the main claim.

The design according to the invention makes the function the pump is replaced by simple physical principles: the suction lift principle is used to fill the storage container and the force of gravity is used to transport the liquid into the discharge line. 10

Claim 2 describes a particularly advantageous way to move the storage container in height on the device hold.

Claim 3 describes a way to ensure

that the liquid completely filling the suction tube cannot flow back into the container, so that when the container is tilted, no air bubbles which impair the suction lifting effect are formed.
20th

Due to the configuration according to the dependent claims 4 to On the one hand, the amount of liquid flowing out of the storage container into the discharge line can be regulated.

On the other hand, this can, especially with the new ^!

after a fluid change it will be necessary to fill the suction line to the brim so that it can be filled can act as a suction cup.

An embodiment of the invention is based on the following the drawings explained in more detail. Show it

From Figures 1 and 2, a cleaning device designated as a whole by 1 can be seen. The cleaning device 1 consists

from a frame 3 which is movable on castors 2. The frame 3 5

has a frame base 3a on which a container 4 for cleaning fluid can be provided. The clear inside width of the frame 3 above the frame base 3a is expediently dimensioned so that the commercially available container sizes, especially barrels or cans, can be accommodated can be. A work basin 5 is arranged on the frame 3 above the container 4. The work basin 5 has the shape of a tub with a perforated Intermediate floor 6. Below the intermediate floor 6 is that

Working basin 5 provided with a return line 7, the 15th

opens into the container 4 just above its bottom. The return line 7 is marked with a not shown, Equipped with a filter screen that also acts as a flame protection screen. Above the work basin 5 is a lower

_{A storage container 8 is arranged on the} right extension 3b of the frame 3. A discharge line 9, which leads to the cleaning tool, in particular the paint brush or the brush, is connected to the lowest point of the storage container 8. The highest point of the storage container 8 is provided with an opening 11, the size of which can be varied by a regulating screw 13 seated on a pipe attachment piece 12. The storage container 8 and the container 4 are connected to one another via a suction line 14 which opens into the container 4 above the return line 7. The suction line 14 has a return valve 15 which is preferably arranged at the lower end opening into the container 4. The return valve 15 blocks the return flow in the direction of the container 4. The inlet of the return valve 15 is expediently covered by a sieve acting as a filter. In the storage container 8, the suction line 14 opens in the vicinity of the opening 11. At least part of the suction line 14 running between the storage container 8 and the container 4 is designed to be flexible.

The part of the vertical extension 3b on which the reservoir 8 is attached is via a hinge 16 with

the frame 3 connected. The joint 16 is designed in such a way, 5

that after loosening a tilt lock 17 from the fixed part the extension 3b of the reservoir 8 with the movable part in the direction of the arrow in the dashed line Filling position can be pivoted. The distance between

the hinge and the lower edge of the storage container 8 is 10

equal to or greater than the distance between the joint

16 and the normal level of the cleaning liquid in the container H. The distance between the axis 16 and the storage container 8 is expediently so great that the storage container 8 even then is still below the level 15

the cleaning liquid is when the container 4 an amount of cleaning liquid corresponding to the capacity of the storage container 8 has been withdrawn. The capacity of the reservoir 8 can be varied within wide limits _n, depending on the used cleaning liquid or, depending on the intended use.

The operation of the cleaning device according to the invention is as follows: On the frame base 3a is first the

₂ c container 4, filled with an appropriate cleaning liquid, provided, the return line 7 and the suction line H being housed in the container. Then the regulating screw 13 on the reservoir is loosened and the suction line 14, possibly with the aid of

QQ would take a funnel filled to the top with cleaning fluid. The check valve 15 prevents this cleaning liquid from running into the container 4. Then the opening 11 is completely closed by the regulating screw 13 and the storage container 8, after loosening the tilt lock 17, is pivoted into the filling position shown in dashed lines. The cleaning agent from the container H now runs through the suction line into the storage container 8 until it

is filled. Finally, the storage container 18 is again

pivoted into the working position and secured with the anti-tip device 17. The cleaning device is now ready for use. If the regulating screw 13 is now opened, b

the cleaning liquid thus runs out of the storage container 8 through the discharge line 9 under the action of gravity to the brush 10. By regulating the size of the opening 11, the flow rate or the flow rate of the Cleaning agent from the reservoir 8 can be regulated. The used cleaning agent runs through the perforated Intermediate floor 6 and the return line 7 back into the container 4. Since the return line 7 below the suction line opens into the container 4, it is ensured that not too much of the used cleaner in the next suction process is sucked in again. After the cleaning liquid from the storage container has been used up, the filling process can start start all over again.

The invention is not limited to what is described and drawn Embodiment limited.

When using the device according to the invention for filling "of Batteries will proceed as described above, with all Parts that come into contact with the liquid are made of acid-resistant material and the brush is through an appropriately designed filling valve is replaced. The batteries are placed in the work basin and can be filled on the spot.

Design changes are also conceivable: for example, the non-return valve in the suction line can pass through other unilateral blocking agents are replaced. Also the end of the suction line opening into the storage container can be secured with an appropriately designed backflow protection. Finally, the reservoir can instead of being swiveled, also lifted into the working and filling sections and hung or by hand

drive to be moved.

The device can be used except for cleaning agents and battery fluid can also be used for other liquids it is expedient to attach the tool or the fitting to the discharge line in an exchangeable manner.
