Abstract
The utility model relates to a no-clean drilling fluid water loss instrument, and mainly solves the problem of the conventional drilling fluid water loss instrument that the cup body of the instrument is difficult to clean after use. The water loss instrument is characterized in that a plastic inner lining cup is arranged in the cup body; a seal ring is arranged between the lower surface along the upper opening of the plastic inner lining cup and the upper edge opening of the cup body; filter paper, a filter screen and a cup lid are arranged at the upper opening of the plastic inner lining cup in sequence; a guide pipe is arranged in the cup lid; one end of the pipe orifice of the guide pipe is communicated with the filter screen, and the other end thereof penetrates a hole formed on the cup body in a position near the cup opening and a hole on the side wall of an upper lid, and then extends out of the cup body; an annular space is formed between the inner side wall of the cup body and the plastic inner lining cup; an air inlet on the outer side wall of the cup body is communicated with the space; and the upper lid is tightly propped against the cup lid of the plastic inner lining cup through a compression bolt. The cup provided in the utility model can eliminate the trouble of cleaning the cup body after use.
Description
Technical field
The utility model relates to a kind of drilling fluid dehydration device, a kind ofly specifically exempts to clean the drilling fluid filter press.
Background technology
In order to detect the drilling fluid dehydration and to check that the content of tracer in the drilling fluid need be with a kind of drilling fluid dehydration device, the liquid in the drilling fluid is leached analyze.Existing drilling fluid filter press is by lower cover, cup, loam cake, filter paper and seal five parts and form.During operation, earlier filter paper is opened, put to lower cover, load onto cup and pour drilling fluid into, then fixed cover, feed source of the gas, drilling fluid flows out from the lower cover of drilling fluid filter press under pressure.This kind operation, drilling fluid directly contacts with cup, and because this drilling fluid filter press structure relative complex, volume is also bigger, and it is very difficult to clean the filter press cup behind the end-of-job, and is difficult for cleaning up, and whole operation is more loaded down with trivial details.
The utility model content
The technical problems to be solved in the utility model provide a kind of need not clean cup exempt to clean the drilling fluid filter press, this filter press is to put into the plastic inner lining cup in cup, avoid drilling fluid directly to contact with cup, behind the end-of-job, plastic inner lining cup and surplus drilling fluid are taken out together, needn't clean cup.
The technical solution of the utility model is: a kind ofly exempt to clean the drilling fluid filter press, the loam cake that is equipped with suitable for reading that comprises cup, on the sidewall of cup air inlet port is arranged, be built-in with the plastic inner lining cup, be equipped with sealing ring between the upper edge soffit of plastic inner lining cup and the upper edge hole of cup at described cup; And filter paper, filter screen and the bowl cover of being equipped with successively suitable for reading of plastic inner lining cup has conduit in the bowl cover, and the mouth of pipe one end of conduit communicates with filter screen, and the other end passes on the cup successively near stretching out outside the cup behind the hole at rim of a cup place and the hole on the loam cake sidewall; Between its inside wall of described cup and plastic inner lining cup annular space is arranged, the air inlet port on cup lateral wall space therewith communicates; Loam cake holds out against the bowl cover of plastic inner lining cup by hold-down bolt.
The beneficial effects of the utility model are: owing to adopt said structure, the plastic inner lining cup is set in cup, during the dehydration operation, cement is directly packed in the plastic inner lining cup, does not contact with cup, behind the end-of-job, plastic inner lining cup and surplus drilling fluid are taken out together, needn't clean cup; Compared with prior art, reduced lower cover part and corresponding link, thereby also reduced the certain operations link on the structure, volume also reduces relatively, can be placed directly on the workbench to operate.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing 1, this exempts to clean the drilling fluid filter press, comprise cup 1, plastic inner lining cup 3, liner cup bowl cover 8, cup loam cake 10, wherein cup 1 is built-in with plastic inner lining cup 3, be equipped with sealing ring 4 between the upper edge soffit of plastic inner lining cup 3 and the upper edge hole of cup 1,3 in sealing cup 1 inwall and plastic inner lining cup form annular space; And plastic inner lining cup 3 suitable for reading put filter paper 6 is arranged successively, filter screen 7 and bowl cover 8, conduit 5 is arranged on the bowl cover 8, two mouths of pipe, one end of conduit 5 communicates with filter screen 7, the other end is crossed on the cup 1 hole and the hole on loam cake 10 sides near the upper edge and is stretched to the outer measuring cup 2 of cup; Described cup 1 its inside wall and 3 in plastic inner lining cup have the ring packing space, and the air inlet port 11 on cup 1 lateral wall communicates in the space therewith; The loam cake 10 that is equipped with suitable for reading of cup 1 has hold-down bolt 9 on the loam cake 10.During use, pour drilling fluid into plastic inner lining cup 3 li, put filter paper 6, filter screen 7 and bowl cover 8 successively at rim of a cup, loam cake 10 is pressed on the bowl cover 8 of plastic inner lining cup 3 by housing pin 9, form annular seal space, gases at high pressure are entered in the toroidal cavity of cup 1 and plastic inner lining cup 3 by air inlet port 11, and the drilling fluid of 3 li in extruding plastic liner cup, and drilling fluid is flowed out in the graduated cylinder 2 by conduit 5 by filter paper 6 and filter screen 7.Behind the end-of-job, plastic inner lining cup 3 and surplus drilling fluid are taken out together, needn't clean cup.This filter press compared with the prior art, has reduced lower cover part and corresponding link, thereby has also reduced the certain operations link on the structure except that needn't cleaning, and volume also reduces relatively, can be placed directly on the workbench to operate.
