Slurry collector

Field of the invention

The invention relates to a water collecting ring according to the preamble of claim 1. 5

PRIOR ART Water-collecting rings are used for the extraction of water and drilling mud in wet drilling. Such water-collecting rings have a housing with an outer and an inner Sing, which are arranged concentrically. At the top 10 the rings are connected by a cover, whereby a cavity is formed between the rings. At the bottom the cavity is open and the edges of the rings are provided with sealing lips. On the outer ring, a suction connection is arranged which can be connected to a suction hose. Water and drilling sludge are therefore collected directly on site at the drilling site in the water collecting ring and can, for example, be sucked off by a wet-dry vacuum cleaner (NT vacuum cleaner). The water collecting ring automatically absorbs itself after switching on the NT vacuum cleaner to the ground and keeps the environment of the drilling site clean from soiling. However, the inner and outer ring must have a certain distance, so that in the cavity 20 formed between the rings, a sufficiently large collecting volume and a sufficient suction effect are present. However, this distance prevents the water collecting ring from being usable in bores which are made a short distance from laterally adjacent walls

The sealing lip of the inner ring has a plurality of passage openings, 25 so that the water or the drilling mud can be sucked into the cavity formed by the two rings. The passage openings are arranged relative to the suction in a fixed position. This results in the disadvantage that if the suction port is not at the lowest point during use of the water collecting ring, the water can be sucked through the through holes of the inner 30 sealing ring when it has dammed and has reached the passage opening Thus, the function of the water ammelrings at positions 24/05/2012 14:39

Object of the invention

It is therefore an object of the invention to provide a water collecting ring, which is suitable for 10 overhead wells. An additional object is to propose a water collecting ring, which is also useful in drilling, which is performed at a short distance to adjacent walls, floors or ceilings or corners become. Another object is to show a water collecting ring whose function is less affected by the days of the suction port relative to the direction of gravity than in the prior art.

description

According to the invention the object is achieved in a water collecting ring according to the preamble of claim 1 characterized in that on the cover a sealing ring 20 is arranged which projects into the passage opening and fluid-tight with the Hohlkembohrer can cooperate, which can be passed through the water collecting ring. The sealing ring is designed to retain the cooling water needed in Kembohrungen within the water collecting ring. As an additional effect, the sealing of the first sealing lip is reinforced by the sealing ring since outside air must overcome the barrier of the sealing ring and the first sealing lip. Especially when the water collecting ring is firmly sucked on ceilings, the additional sealing effect is advantageous because in this position the weight of a connected suction hose acts directly on the water collecting ring. The sealing ring may be fixed to the inside or the outside of the cover. A determination on the outside is ever preferred because the sealing ring is easier to reach in this position. 24/05/2012 14:39

Conveniently, the first sealing lip piece is longer than the second sealing lip piece. As a result, the second Dichtiippenstück extend in the region of the bulge and the passage formed, regardless of which end of the first sealing lip piece he is provided; is always in the area of the bulge respectively. the suction connection. This position of the passage allows a particularly effective removal of the cooling water. 10 15 20

In a particularly preferred embodiment, at least a first sealing lip piece and a second Dichtiippenstück are arranged on the edge of the inner wall, wherein the sum of the lengths of the Dichtlippenstücke is shorter than the length of the edge of the inner wall. Between the at least one first and second sealing piece, a passage is thereby formed in a simple manner, through which cooling water from the passage opening on the inner wall can pass into the intermediate space. As a result, on the one hand an internal pressure between the inner wall and the outer wall is constructed, which is less than the external pressure. As a result, the water collection ring is securely held on ceilings. On the other hand, a passage is formed between the first and second Dichtiippenstück, which serves as an overflow for the cooling water. The overflow is of particular importance if, despite a further cooling water passage, the liquid level in the water collecting ring between inner wall and core drill increases in the case of ceiling bores. The passage between the first and the second sealing lip piece is dimensioned in such a way that even larger amounts of cooling water can be transported away and the water collection ring still reliably held by the oppressive on the ceiling 25

Advantageously, the length of the edge of the inner wall exceeds the sum of the length of the sealing lip pieces by at least 5 mm, preferably by 8 mm and particularly preferably by 10 mm and at most by 25 mm, preferably by 20 mm and particularly preferably by 15 mm. Thereby, a passage between the sealing lips pieces, preferably between the first and second Dichtiippenstück, formed which is dimensioned such that on the one hand sufficient suction is built and on the other hand, no backflow of cooling water builds up in the through hole

In a preferred embodiment, the sealing ring is made of an elastic plastic, in particular a polyester-urethane rubber. This plastic is 24/05/2012 14:40

3500-16731 4 24.052012 due to its mechanical and chemical resistance especially suitable for the present application.

Conveniently, at least one cooling water passage is provided on the inner wall. Therefore, a connected wet-dry vacuum not only sucks air, 5 in the space to create a negative pressure, but also simultaneously sucks off the cooling water of Hohlkembohrers.

Advantageously, the at least one liquid passage in the region of the suction connection is arranged on the inner wall. The cooling liquid therefore only has to travel a short distance in the intermediate space in order to be sucked out of the water collecting ring.

In a further preferred embodiment, the sealing ring is arranged interchangeably on the cover. This feature is necessary so that the sealing ring is exchangeable with other inner diameters for sealing rings. If a hollow core with another core diameter is to be used, then only the sealing ring is to be exchanged and not the entire water collecting ring. Even if the sealing ring is worn, it can be quickly replaced by a new one.

In a particularly preferred embodiment, a screw ring is screwed onto the cover for holding the sealing ring and the sealing ring between the screw ring and cover can be clamped. A ring gear is a cost-effective solution for producing a releasable connection between the sealing ring and the cover. A ring with an external or internal thread can be produced in one piece with the cover, onto which the ring screw can be screwed with an internal or external thread. The sealing ring can be jammed between the screw ring and the cover. 25 Preferably, the screw ring is held with a bayonet lock on the cover. This allows a particularly rapid connection with a defined clamping of the sealing ring.

In a further particularly preferred embodiment, the housing is made of a transparent material, in particular a transparent plastic. 30 The user of the water collecting ring is therefore constantly during a core drilling 24/05/2012 14:40

Advantageously, the outer wall has a bulge, such that the distance between the edges of the inner and outer wall in the region of the bulge ver-5 is greater. As a result, the intermediate space in the region of the bulge has a larger partial volume. Due to the increased partial volume in the area of the bulge, the volume of the space between the inner wall and the outer wall in the rest of the water collecting ring can be reduced without the suction power of the water collecting ring would suffer. The distance between the inner wall and the outer wall can therefore be reduced. This has the advantage that the water collecting ring can also be used for example in corners of two adjacent building walls and the borehole is providable at a short distance to the adjacent building wall. The distance of the borehole from the adjacent building wall is limited only by the distance between the inner wall and the outer wall first sealing lip piece longer than the second sealing lip piece. As a result, the second sealing lip piece can extend in the region of the bulge and the passage formed, regardless of which end of the first sealing lip piece it is provided, is always in the region of the bulge, respectively. the suction connection. This position of the passage allows a particularly effective removal of the cooling water.

It proves to be advantageous if the second Dfchüippenstück along the edge of the inner wall in the region between the ends of the first Dichtlippenstücks is displaced This displacement causes the passage to the position of the water collecting ring relative to the vertical is adaptable. Depending on whether the exhaust port is rotated clockwise or counterclockwise, the port can be moved with it. This is especially useful when the water collecting ring needs to be twisted relative to the vertical to allow easy access to the suction port even in confined spaces. It is also conceivable that the second sealing lip piece is arranged between the two ends of the first sealing lip piece such that a passage is formed on both sides. This arrangement may be advantageous if the suction connection is arranged substantially vertically on a building wall It is also conceivable that the inner wall 24/05/2012 14:41

This aspect ratio of the first sealing lip piece to the second sealing lip piece causes the passage does not shift into a Be-rich range in which it is too far away from the suction for effective suction would.

Because the suction connection is advantageously arranged on the bulge, the suction effect in the region of the bulge, in which the cooling water collects, is greatest. To increase the suction effect, it is advantageous if the suction connection 15 takes the lowest possible funct depending on the position to the vertical so the effect of gravity to support the suction is maximally utilized

Advantageously, the inner wall has the shape of a ring to keep the distance to a drill or core drilling which are necessarily round, as small as possible over the entire circumference 20.

In a further preferred embodiment, the outer wall has substantially the shape of a ring, wherein the ring is widened in the region of the bulge. As a result, the inner wall in ring shape can be arranged concentrically within the outer wall. This causes the smallest possible distance between the aus-25 senwand to the inner wall.

As already stated in the last paragraph, the inner wall is expediently arranged concentrically within the outer wall in order to ensure the smallest possible same distance between inner wall and outer wall.

It proves to be advantageous, when the inner wall and the outer wall are connected at the side facing away from the 30 sealing lips by means of a cover, which cover protrudes into the passage opening. As a result, the cover forms an overlap 24/05/2012 14:42

3500-16731 7 24.05.2012 if the cooling water is temporarily not fully immersed in the water. Space is sucked out.

Advantageously, the cover forms an overflow protection in the area of the bulge by projecting more strongly into the through-hole in this area than in the remaining areas of the through-hole. As a result, the overflow protection is highest in the area in which the water has the effect gravity is normally collected in the passageway. hi another preferred embodiment, the suction is arranged at the transition between the outer wall and cover obliquely to the level of the outer wall to-10 The suction connection is therefore particularly easy zuzuschKessen to the suction hose of a NT-suction, since it is directed away from the building wall and this thus when Connection is not in the way.

In a further preferred embodiment, the distance of the outer wall from the inner wall, except for the area of the bulge, is at least 5 mm, preferably 10 mm and more preferably 15 mm and at most 35 mm, preferably 30 mm and particularly preferably 25 mm. This dimensioning of the distance causes the smallest possible distance between the inner wall and outer wall, whereby the water collecting ring can be used very close to an adjacent building wall. On the other hand, the distance is not so small that the suction 20 is impaired.

Since the displaceability of the second sealing lip piece does not necessarily have to be combined with the bulge feature, another aspect of the invention concerns a water collecting ring in which at least one first sealing lip piece and one second sealing lip piece are disposed at the edge of the inner wall, thereby shortening the voice of the lengths of the sealing lip pieces As the length of the edge of the inner wall is This arrangement of two lip pieces is not only suitable for new water collecting rings, but it can also each existing water collection ring with two such sealing lips pieces are equipped afterwards.

The inner wall 13, the outer wall 15 and the cover 17 define a gap 21, which is open when using the water collecting ring 13 in the direction of the building surface At the edges of the inner and outer wall 13,15 are a stern and second sealing lip 5 23, 25 provided. The sealing lips 23,25 serve the most fluid and airtight possible

Completion of the water collecting ring 11 on the building wall, when the Wassereammel ring 11 is connected to a wet-dry vacuum cleaner, for example, the sealing lips 23,25 may be frictionally held at the edges of the inner or outer wall 13,15 by a wire-reinforced U-profile made of rubber, 10 which can be attached to the edges The area adjacent to the U-profile can also be made of rubber, which is deformable during the suction Thus, the water collection ring 11 holds independently on the building wall and cooling water and drilling mud remain Mostly in the intermediate space 21 and are sucked through a suction port 27 Preferably 15 is the suction port 27 to a suction.

FIGS. 1 to 5 show a sealing ring 33, which is arranged on the cover 17. The sealing ring 33 may be arranged on the outside or the inside of the cover 17. The sealing ring 33 protrudes into the passage opening 19. The inner diameter of the sealing ring 33 is smaller by 10 to 30 mm, preferably by 15 to 25 mm 20 and more preferably by 18 to 22 than the diameter of the passage opening 19. In order for a sufficient seal between the cover 17 and the sealing ring 33 must be produced the sealing ring 33 have a sufficient contact surface on the cover. Accordingly, the outer diameter of the sealing ring 33 by 10 to 30 mm, and preferably by 15 to 25 mm larger than the diameter of the passage opening 19. The inner diameter of the sealing ring 33 is dimensioned such that the shell of a Hohlkembohrers substantially fluid-sealed with the sealing ring. The inventive water collecting ring 11 allows that the cooling water of the hollow core drill can not escape from the through hole 19. Therefore, it is also possible to make holes on ceilings. The cooling water is discharged through the suction connection through at least one cooling water passage 35 which penetrates the inner wall 13 in the region of the suction connection 27 at the same time as the air flow which serves to suck in the water collecting ring

Depending on the amount of cooling water required, a plurality of cooling water passages 35 can penetrate the inner wall 13. The feature of a sealing ring 33 is additionally characterized by the fact that the seal between the sealing ring and the hollow core drill additionally improves the suction performance of the water ring. This is because the seal on the inside of the gap 21 of the first sealing lip 23 is further improved by the sealing ring 33, since outside air has to overcome the barrier of the sealing ring 33 and the first inner sealing lip 23.

For exchangeable fixing of the sealing ring 33 on the cover 17, the sealing ring 33 can be clamped in a fluid-tight manner with a screw rim 37 between the same and the cover 17 1Q. For a particularly rapid and simple mounting of the screw ring 37 is preferably fixed by means of a bayonet lock on the cover 27. Ie. with a small clockwise rotation of the sealing ring 33 is fixed. Just as quickly can the sealing ring 33 by turning counterclockwise and removing the ring gear 37 cooked exchange another sealing ring-15. This may be necessary if a sealing ring is to be used with a different inner diameter, or the sealing ring 33 has to be replaced for reasons of wear against a new sealing ring. The sealing ring 33 is preferably made of a polyester-urethane rubber, also known under the trade name Vukollan. This elastic material has good chemical and mechanical resistance and is very well suited for the present application. A thickness of the sealing ring 33 of at most 1 mm is sufficient to produce a sufficient seal between the sealing ring 33 and the Hohlkembohrer.

The housing of the water collecting ring 11 is preferably transparent Expediently, any transparent plastic with sufficient mechanical and chemical resistance can be used. In particular, when the water collecting ring in the production of a Kembohrung on a ceiling, so over head, is used, a transparent design of advantage. The user is informed at all times about the liquid level of the cooling water due to the transparency of the housing and can therefore respond in good time to an overfilling of the water collecting ring.

As shown in Figures 2 to 4, the suction port 27 is preferably made obliquely and penetrates the outer wall 15 and the cover 17. This is a suction 24/05/2012 14:44

The outer wall 15 preferably has a bulge 29 in the region of the suction connection 27. By enlarging the distance of the intermediate space 21 5 in the region of the bulge 29, it makes possible the distance between the inner wall 13 and the outer wall 15 in the region which adjoins the bulge 29 -complies to decrease without compromising the suction performance. Due to the small distance of the inner and outer walls 13,15 of the water collecting ring 11 is still applicable even if the building wall bore at a small distance to an adjacent building wall, ie in a corner, make is preferably the distance between the inside and the External wall 13,15 in about 20 mm. This ensures adequate suction and drilling or Kembohnmgen can be made up to a distance of about 20 mm to an adjacent building wall. The second sealing lip 25 is continuously closed so that no liquid can leave the intermediate space during the use of the collecting ring 11. In contrast, the first sealing lip 23 is interrupted and has at least one passage 31 through the cooling water and drilling mud from the Durchgangsöffmmg 19 in the gap 21 can flow. The first sealing lip 23 preferably consists of a first sealing lip piece 23a and a second sealing lip piece 23b. So that the passage 31 is formed, the sum of the sealing lip pieces 23a and 23b is shorter than the edge of the inner wall 13. The length of the second sealing lip piece 23b is preferably about 1/3 of the length of the first sealing lip piece 23a. The second sealing lip piece 23b can be plugged onto the edge of the inner wall 13 since the edge Eugcwandte side vo * uugoweiae «Yes a dfohtvontiiiktac U-profile» ucgafülvrt is the second sealing lip piece 23b is therefore displaceable between the two ends of the first sealing piece 23a.

FIG. 8 shows that it is also possible to arrange the second sealing piece 23b centrally between the two ends of the first sealing piece 23a. Then, two passages 31a / 31b are formed, the total width of which corresponds to the width of the passage 31. The displacement of the passage 31 has the advantage that the passage 31 depends on the position of the water 24/05/2012 14:45

If the suction connection 27 is twisted to the left or right from the vertical, for example for reasons of space, the passage 31 can be displaced in the direction of the suction connection 27. As a result, the suction power can be improved, since the path of the cooling water or of the drilling mud in the intermediate space 21 can be kept as short as possible and the cooling water can flow essentially in the direction of gravity. The two sealing lip pieces 23a, 23b can also be used in the application of the water collecting ring 11 in the case of ceiling bores. The passage 31 may then be provided in addition to the cooling water passage 35 to form an overflow. By the over-10 running cooling water can flow, if the cooling water rises in the water collecting ring between the inner wall 13 and Kembohier

In summary, the following can be stated: For collecting and exhausting cooling water and drilling mud during a wall or core drilling a erfmdungsgemässer water collection ring 11 is used. The feature of the sealing ring 33 is distinguished by the fact that a core bore can also be carried over the head using the water collecting ring 11 according to the invention, since the cooling water is retained in the water collecting ring 11 by the sealing ring 33. By providing the bulge 29 in the region of the outer wall 15, the partial volume of the intermediate space 21 in the region of the bulge 29 is increased. As a result, the distance between the inner wall 13 and the outer wall 15 in the remaining region adjoining the bulge 29 can be reduced. The space requirement of the water collecting ring 11 is correspondingly low and it can be arranged closely to an adjacent building wall, so that even in the through hole on taken wall or Hohlkembohrer close to the adjacent building wall ge-25 can be performed.

The first sealing lip 23 may be composed of a first sealing lip piece 23 a and a second sealing lip piece 23 b. The two sealing lip pieces 23a, 23b are spaced apart by at least one passage 31. The passage 31 allows cooling water to flow from the passage opening 19 through the inner wall 30 13 into the clearance 21. By moving the second
