5 Samplers ¹

7 The present invention relates to a sampler for separators,

8 For example, light liquid separators according to the generic term of the main

9 claim.

11 Light liquid separators, especially petrol separators, are now much—

12 times in use, These are often older facilities,

13 which are not usually equipped with sampling devices.

14 are permitted. However, such sampling is now mostly permitted by the authorities

15 to ensure the functionality and quality of the

to be able to check the light liquid separator again and again. The product

17 removal takes place in the drainage area or in the outlet of the separator, because only

The separation result can be reliably checked there.

20 Such separators are usually installed underground in a fixed location, with the

21 retrofitting such separators with a sampling facility

22 possibility for already installed systems is very complex and often even

23 subsequent earthworks required.

25 For example, for newly installed separators, Dywidag supplies

ze light liquid separators (coalescence separators) with a permanently installed

27 Suction line for sampling. The suction end of this suction line is connected to

28 coupled to the separator outlet, while the discharge end is slightly below

29 below the level of the closure plane, i.e. the cover or the cover

30 kels. To take a sample, only the lid needs to be removed.

31 and a pump must be coupled to the extraction end.

32 Such quick couplings are widely used, for example, in the

33 ten irrigation technology known.

35 Dywidag supplies foot-operated piston pumps for sampling, each of which

36 are comparatively expensive. For sampling, this pump is used by

37 provided to an operator. It can therefore be assumed that this sampling is carried out at a large number of individual separators, each with the

&igr; same pump, thus separating the pump from a separator

2 must be transported to the next separator.

4 The present invention now aims, starting from this known state

β of the technology aims to improve the possibility of taking samples at such

6 separators as simple and inexpensive as possible. Furthermore, the

7 The invention aims to design the sampler in such a way that it is as

8 space-saving, especially in the immediate area of the separator, storage

9 bar, so that it can be refilled even after a long period of non-use.

10 to be available in a ready-to-use condition.

12 To solve this problem, the sampler according to the invention is for

13 separators according to the characterizing features of the main claim

&kgr;. Because the pump is a hand piston pump with double

is formed by an effective pump piston, a simple mass article can be produced

ie very low costs for its production. Such a hand-

17 piston pump consists essentially only of the pump cylinder, the

is double-acting pump piston and a piston connected to the

19 Handle. Such hand piston pumps can be easily made from

20 plastic, as is the case in a preferred embodiment of the

21 present invention corresponds

23 By replacing known, relatively expensive foot piston pumps with a

24 Hand piston pump, as proposed according to the invention, a

25 such a reduction in the cost of the sampler that each liquid sample

26 separators can be assigned their own pump. This allows

27 already in the soil, but not yet with a sampling

28 separators provided with a sampling option can be retrofitted

29 possibility at reasonable cost, whereby the fact that this pump is only comparatively rarely activated, due to the fact that such

31 Checks are usually carried out only at long intervals, one of the

32 type pump is also subject to significantly less wear, although this

33 ensures a sufficiently long service life. For the training of the pro-

34 user, it is still assumed that the operator of a waste-3s separator in accordance with the currently applicable provisions has the possibility of removing

36 possibility for an official inspection, whereby practically

37 objective verification should be possible at any time. With the inventive

&igr; The use of a hand piston pump is recommended for this check.

2 possibility of implementation at very low cost.

4 Apart from the advantages associated with the use of a hand piston pump for the manufacture

5 The low costs associated with the design and use of this pump allow

6 due to the fact that such a hand piston pump is usually

7 can be designed to be quite small, a protected housing or storage of this pump can be achieved. According to the invention, the pump is

9 rer non-operating position by at least one housing part in the area of

10 suction connection, which protects the particularly sensitive

11 inlet opening into the interior of the pump in the usually quite long outside

12 operating times. Alternatively, due to the small construction

13 The design of such a hand pump can also be such that the pump can be stored completely in a housing with at least one removable cover, whereby the housing can, for example, have the shape of a quiver that can be closed on all sides, with which the pump can be easily stored in the separator itself or in the area of a withdrawal or suction line and is thus available at any time for inspection or sampling. If a plurality of separators are on re-

20 relatively limited space, such a

21 protected sampler can naturally also be stored at any

22 other place, whereby the cover or

23 the housing is closed on all sides and ensures at all times that the

24 Samplers immediately in a condition suitable for use

25 finds.

27 For easy storage or securing of the pump in its protected

28 or in a housing state, preferably the

29 Housing or housing part has a fastening or suspension element.

30, wherein according to a particularly preferred embodiment of the

31 sampler according to the invention has the features of claim 3.

32 By using a housing wall or a removable cover

33 penetrating chain, this housing part or the removable cover

34 secured to this chain when the pump is in use, so that a loss during

35 operation of the pump is largely excluded. In addition, the eyelet fixed at one end of the chain provides a simple

37 Fastening of the housing with the pump inside, for example

38 on a hook in the area of the extraction or suction line of the

&igr; scheiders. As explained above, protection in the area of

2 suction connection of the pump if it is not in use for longer periods.

3 drive is particularly important. For this purpose and for proper

4 Locking of the housing part to the pump cylinder is the inventive

5 appropriate samplers further preferably according to the characteristic features

6 len of claim 4. Such locking projections and/or

7 -Recesses can be in the form of a bayonet lock

8, which allows the connecting elements to be connected with each other in a simple

&bgr; connecting parts can be easily fixed together and at the same time

10 Any seals required can be easily accommodated

13 In order to ensure a good seal in the case of a housing that does not completely accommodate the pump,

µm appropriate safety of the interior of the pump cylinder, in particular

is protected against the ingress of dirt in the area of the operating handle

ie or the actuating device of the pump piston, to be used as far as possible

i7, the sampler according to the invention is also designed according to the

is further developed with the characterizing features of claim 5.

29 can.

si For a particularly simple and cost-effective production of the housing parts

32 or the fully enclosed housing or quiver for the

33 Hand piston pump, the design is preferably according to the characteristics

34 of claim 9. This results in the use of an all-

35 sided closed housing in the form of a simple tube, that its

36 diameter only slightly exceeds the outer diameter of the pump cylinder

37 or the dimensions of the manual operating handle of the pump piston.

38. The suction hose is generally flexible enough to fit into a tight
