Definitions

  • the invention relates to a pump device according to the preamble of claim 1
  • Pumping devices are known in which the pump is connected via a connection to a connection of a container. In these known pumping devices, there is the danger that larger residual quantities remain in the container, since they can not be properly sucked off.
  • the invention has the object of providing the generic pump device in such a way that the remaining amount remaining in the container is minimal.
  • the pump rotor is located in the region below the bottom of the container.
  • residual fluid can flow out of the container into the pump, where it can be conveyed on easily by the pump rotor.
  • the inventive construction makes it possible in a simple manner to empty the container substantially completely.
  • the pump device has a pump 1 with which the contents of a container 2 can be pumped out. It may consist of any suitable material, in particular plastic.
  • the container 2 is located in a cage 3, which encloses the container 2 on all sides and supports.
  • the cage 3 has intersecting cage bars 4, which are located on the side walls of the container 2 at a distance from each other.
  • the lower ends of the vertical cage bars 4 are connected to a lower frame 5 with which the container 2 stands on a base 6.
  • the upper ends of the vertical cage bars 4 are fixed to a frame 7, which in plan view according to Fig. 3 surrounds the container 2.
  • the frame 7 has a rectangular outline and is stiffened by two transverse bars 8 ', 8 "parallel to one another and spaced apart from each other and the frame sides, which connect opposite sides of the frame 7. It can rest against the top of the container 2.
  • the cage 3 prevents buckling of the container 2 in the filled state.
  • the cage bars 4, 8 ', 8 “have a small thickness and consist of metal.
  • the pad 6 is advantageously a pallet that can be transported, for example, with a forklift.
  • the container 2 is provided in the embodiment on its narrow side near the lower edge with a small distance above the lower frame 5 with an outlet opening 10 to which a pipe extension 12 connects.
  • a closure element 11 is mounted, with which the pipe socket 12 can be opened or closed.
  • the closure element 11 is designed as a closure cock with an actuating lever 13.
  • On the free end of the pipe socket 12 a (not shown) lid is screwed advantageously, so that the container 2 can be easily transported.
  • the tube extension 12 is located in a recessed relative to the outer side 14 of the container 2 area 55, which is advantageously so deep that the tube extension 12 is not or only slightly on the outside 14 of the Container 2 protrudes.
  • the pump 1 is screwed.
  • a pump tube 15 which projects into a pot 25.
  • a transversely, preferably perpendicular to its axis projecting connecting piece 16 is provided, which is provided at the free end with an external thread 17.
  • a hose 19 is attached to the connecting piece 16 with a threaded ring 18 with the interposition of a ring seal, which at the other end with a tap 20 (FIG. Fig. 1 ) is provided. He is trained in a known manner and is therefore not described in detail.
  • a hook 21 may be hung, in which the tap 20 can be mounted. Since the frame 7 projects beyond the top of the container 2, the hook 21 can be easily attached to the container 2.
  • a strain relief 22 e.g. a hose clamp, provided for the hose 19.
  • the strain relief 22 prevents in use of the pump device, the pump hose 19 is accidentally torn off the connecting piece 16.
  • the tube 19 is sufficiently long, so that the medium from the container 2 can be easily transferred.
  • the pump tube 15 has at a distance below the connecting piece 16 a radially extending annular flange 26, which serves as a cover for the pot 25. He surrounds the mounted in the mounted position of the pump 1 lower pipe end and serves to receive the sucked from the container 2 liquid.
  • the pot 25 has a radially projecting tubular elbow 24, at its free end a connecting element, preferably a freely rotatable threaded ring 23, is provided which is secured against removal from the elbow 24 and with which the pump 1 is screwed onto the pipe socket 12 of the container 2 can be ( Fig. 6 ).
  • the flange 26 of the pump tube 15 has a spaced from the outer edge inwardly projecting annular collar 27, with which the flange 26 engages in the pot 25.
  • the annular collar 27 abuts against the inner side 28 of the pot 25, which has the same diameter at the upper end as the flange 26. It forms a lid for the pot 25 and is releasably mounted on a radially distributed with distributed over the circumference of screws 29 and the like outwardly projecting flange 30 is attached to the upper edge of the pot 25.
  • a seal 58 which surrounds the annular collar 27.
  • the pump tube 15 is at its lower end on the bottom 31 of the pot 25, which widens steadily from the bottom 31 to about half the height of the pot.
  • the pot 25 In the upper part, to which the elbow 24 connects, the pot 25 has circular inner and outer cross-section.
  • the pump tube 15 is provided at the lower end with suction openings 49 through which the medium is sucked into the pump tube 15.
  • the funnel-shaped wall of the pot 25 Immediately above the bottom 31, the funnel-shaped wall of the pot 25 has an outlet opening 32, which is closed with a closure member 33, such as a plug or the like. Via this opening 32, residual liquid can be drained from the pot 25.
  • the pump tube 15 is provided with a connecting flange 34, to which a pump motor 35 can be connected.
  • a pump shaft 36 is rotatably mounted in the pump tube 15. It carries at one end a pump rotor 37 which is formed in a known manner and advantageously screwed onto the end of the pump shaft 36.
  • the pump rotor 37 is advantageously made of plastic.
  • a metallic threaded ring 38 is embedded, with which the rotor 37 is screwed onto the lower end of the pump shaft 36.
  • a coupling part 39 is screwed, which cooperates with a counter-coupling part of the pump motor 35 when the pump 1 is connected to the pump motor 35.
  • the coupling part 39 is advantageously made of plastic, in which a metallic threaded ring 40 is embedded, with which the coupling part 39 is screwed onto the pump shaft 36.
  • the connecting flange 34 is part of an insert body 56 which is inserted into the upper end of the pump tube 15 and fixedly connected to it.
  • the insert body 56 has a bottom 41 through which the pump shaft 36 protrudes and in which a bearing 43, preferably a ball bearing, is accommodated for the pump shaft 36.
  • the bearing 43 is preceded by a seal 47, which is also housed in the bottom 41 of the insert body 56 and prevents the access of medium to be pumped to the bearing 43 along the pump shaft 36.
  • the coupling part 46 is recessed within the insert body 56th
  • a transverse web 42 is provided in the pump tube 15, in which a bearing 44 is housed for the pump shaft 36. It is surrounded by the pump tube 15 to form an annular channel 50 at a distance. The sucked by the pump rotor 37 medium passes through the annular channel 50 in the connecting piece sixteenth
  • the elbow 24 is designed so that it extends horizontally after connection to the pipe socket 12, but preferably slightly inclined downwards from the pipe socket 12 and the pot 25 is located with the pump 1 with only a small distance next to the end face 14 of the container 2.
  • the pot 25 is so far laterally next to the pipe socket 12 that the operating lever 13 of the closure element 11 can be actuated if necessary.
  • the pump 1 runs upright and thus stands only slightly from the container 2.
  • the elbow 24 is arranged so that its free end is parallel to the outer side 14 of the container 2.
  • the pump 1 is connected to the elbow 24 so that the connecting piece 16 extends approximately parallel to the outer side 14 of the container 2.
  • the pump 1 can also be arranged horizontally or obliquely, wherein the pump tube 15 and the connecting piece 16 are also approximately parallel to the container outer side 14. Even then, it is only slightly off the container.
  • the closure element 11 is then moved to the closed position.
  • the pump motor 35 can be removed.
  • the pump 1 can be removed, it is possible to use it for other containers 2.
  • the pump 1 remains on the container 2, so that the pump can be transported together with the container. It is even possible to refill the container 2, even if the pump 1 is present on the container.
  • the container bottom is formed so that it drops from the center in the direction of the side walls.
  • the container 2 can be transported together with the pump 1. Due to this small projection, an embodiment is possible in which the pump 1 is not detachable, but firmly connected to the pipe socket 12. Then, in any case, the pump 1 always remains on the container 2.
  • the connecting piece 16 for the pump hose 19 may have any desired design.
  • a pipe can be connected to the connecting piece 16 of the pump 1, which extends in this case along the side wall of the container 2, for example, upwards.
  • the pump 1 is designed and arranged on the container 2 such that its rotor 37 lies in the region below the bottom 51 of the container 2 ( Fig. 1 and 6 ). As a result, residual liquid can flow out of the container 2 via the curved piece 24 into the pot 25 and collect in its bottom area. Due to the funnel-shaped taper of the lower part of the pot 25, it is possible to pump even small amounts of residue properly.
  • the position of the pump rotor 37 in the region below the container bottom 51 and immediately above the bottom of the pan 31 ensures that the pump 1 is always supplied with sufficient liquid. This ensures that the residual liquid, which collects in the bottom region of the pot 25, can be easily forwarded.
  • the liquid in the container 2 which just barely covers the bottom flows slowly into the pot 25.
  • the pump rotor 37 pumps this residual liquid off more rapidly as it flows. However, the pot 25 fills up again and again with the residual liquid flowing on, so that the pump rotor 37 always pumps off this residual liquid remaining.
  • the vertical arrangement of the pump 1 on the container 2 also has the advantage that the pump is extremely space-saving attached to the container 2 and therefore requires little space. This situation also has the advantage that on the pump 1 under load, for example by a shock, only small leverage forces act, whereby a loosening or tearing of the pump is reliably avoided.
  • a Einitatiring 52 is provided which surrounds a housing 57 of the pump motor 35 approximately at half the height.
  • the ring 52 lies with a support part 54 (FIG. Fig. 6 ) on a horizontal bar 4 of the cage 3.
  • the ring 52 is formed as a clamping ring which is clamped with a clamping screw 53 on the motor housing 57.
  • the support member 54 is adapted to the shape of the rod 4.
  • the support part 54 has a part-circular shape and rests flat on the rod 4.
  • the pump 1 is on the ring 52 the rod 4 supported so that the connection area of the pump is relieved to the container 2.
  • the shape of the support member 54 depends on the cross-sectional shape of the rod 4th
  • the formation of the Ein strainringes 52 as a clamping ring has the advantage that it can be adjusted by loosening the clamping screw 53 along the motor 35 so that it can be hooked into one of the horizontal cage bars 4.
  • the arrangement of the pump 1 in the lower part of the container 2 also allows smaller people to be able to mount the pump easily and easily. Even if above the container 2 no space is available to insert a container pump through the opening 9 in the container in a conventional manner in the container, a container pump can be used to empty the container as a result of the described training. Since the described arrangement, the pump 1 itself is not immersed in the medium in the container, it is prevented that impurities can pass through the pump in the medium.
