Definitions

  • the invention relates to a peristaltic pump with an arranged in a pump housing at the bottom of the pump hose with elastically deformable wall, the - between two connection ends in a plan view approximately U-shaped - with a part-circularly curved section around a shaft of a rotor within the wall of the hose pump and this is inserted at a radial distance into the pump housing and the cross-section of which is partially changed during the delivery process by at least one organ of the rotor pressing the pump hose against an abutment, reducing the internal volume.
  • Such a peristaltic pump is described in GB-PS 628 785 with a pump hose and pressure rollers, which creates a chamber section closed off by two pinch points in the hose interior.
  • the pressure rollers roll as squeezing organs on the pump hose, which is supported on the housing wall, and with them those pinch points move in the conveying direction, whereby the conveyed material inside the hose is conveyed from the hose inlet to the outlet end of the pump hose; Thanks to the restoring force of the hose wall, the pinch point near the hose entrance causes suction force on the material to be conveyed in an upstream storage container which is drawn in and then transported from the chamber section described above to the outlet end of the pump hose.
  • the roller axes can be moved on a support frame, with the result that inaccurate settings are made especially when untrained personnel put their hands on the hose pump.
  • the inventor has set itself the goal of creating a peristaltic pump of the type described at the outset with which the identified defects are remedied.
  • the rotor is formed like a bowl from a rotor base and a rotor wall and these are directed towards the bottom of the pump housing, the shaft of the rotor being attached directly to its rotor base.
  • the rotor base and the drive shaft of the rotor are to be formed in one piece, that is to say they are designed as a one-piece construction.
  • the rotor ring is formed on one side on the rotor base and the latter is arranged opposite the pump housing base.
  • the housing base can be brought up directly to the rotor base and the harmful space can thus be considerably reduced.
  • a slide shoe - preferably a pair - projects from the rotor wall as the organ squeezing the pump tube with a radially outward sliding surface toward the pump tube.
  • the cantilever width of the sliding shoe is preferably reduced from a maximum to both sides of the sliding surface; the diameter of the rotor through the maximum serves as a line of symmetry.
  • its outer contour corresponds in plan view approximately to that of a half oval cut in its long axis.
  • the sliding shoe between the sliding surface and the rotor is provided with through openings for lubricants or coolants, the sliding surface preferably being formed along a wall of the sliding shoe and this can limit the through openings in the sliding shoe.
  • the rotor base is also provided with at least one opening for the lubricant or coolant, it being possible for at least one of the openings in the rotor base to be adjacent to the sliding shoe.
  • the breakthrough is assigned at least one conveying scoop which rises from the rotor bottom and can extend, for example, from the maximum of the sliding shoe on both sides along the side edge of the opening in the rotor bottom.
  • the latter provisions serve to optimize the lubrication and cooling of the sliding block and the pump hose; the lubricant / coolant level is increased to such an extent that an increased lubricant / coolant flow and an even temperature distribution over the pump housing are possible due to the delivery vanes on the pump cover side of the rotor and through the passage openings in the slide shoe as well as the backflow openings in the rotor base.
  • a peristaltic pump 10 has, in a bowl-like pump housing 12, an inner diameter d of approximately 320 mm and a height h of approximately 75 mm, a rotor 14 which can be rotated on a pump shaft 16 about its axis line A.
  • the pump shaft 16 is mounted in the region of a central bearing neck 18, which has an average outside diameter b of approximately 95 mm, of the pump housing 12, which is made of rigid material and is preferably cast from metal, by means of an axial bearing 20 and a radial bearing 22, between which a spacer bush 24 the pump shaft 16 surrounds.
  • This spacer bush 24 is surrounded by a locking ring 26 for the axial bearing 20 and a locking ring 27 for the radial bearing 22.
  • a space for bearing grease between the locking rings 26, 27 is designated, with 30 a spacer ring for the thrust bearing 20 within an intermediate ring 26a, which an outer splash ring 32 is adjacent.
  • a sealing element 34 adjoins the radial bearing 22 on the rotor side on an outer support ring 27a towards the rotor 14.
  • the bottom 38 integrally formed on the wall 36 of the pump housing 12 is made up of a bottom section 38a with a cross-sectional length n of approximately more than 55 mm, which is approximately perpendicular to the wall 36, and an inclined angle starting from the latter at an inclination angle w of approximately 120 °
  • the bearing neck 18 protrudes slightly with an annular rib 19 receiving that WDR element 34 axially over the annular bottom portion 38c to the rotor 14.
  • the rotor 14 integrally formed on the pump shaft 16 is also bowl-shaped with a rotor wall 15 immersed in the channel space 40 filled with lubricant or coolant and extending from a rotor base 13, and from its outer surface there are molded knobs 42 and Top view of horseshoe-like conveyor blades 43. These surround openings 44 in the rotor base 13, as shown in particular in FIG. 1.
  • the outer diameter a of the rotor 14 measures approximately 220 mm, so that the mean radial distance i of the rotor wall 15 in that channel space 40 from the housing wall 36 is calculated to be almost 50 mm.
  • the runner wall 15 is penetrated by two screws 45 for attaching an adjusting plate 46 and a sliding shoe 48, which according to FIG. 1 offers a curved sliding surface 49 with a maximum distance q of somewhat more than 20 mm from the runner wall 15 and one through an angle t of a length of approximately 65 °.
  • the contour of the sliding surface 49 in plan view corresponds approximately to that of a half oval, cut in the longer axis of the oval.
  • the slide shoe 48 which is provided with triangular through openings 47 in plan view, partially compresses a pump hose 50 of an outer diameter e of approximately 52 mm, which is arranged in its groove 40 between the wall 36 of the pump housing 12 and the rotor wall 15, during rotation of the rotor 14 that the volume of the tube interior 51 temporarily goes to zero and so within the pump tube 50 a delivery chamber for the medium to be delivered - for example paint, industrial lye or the like. - arises; this is carried along by the described pinch point during the rotation of the rotor 14.
  • the pump hose 50 made of flexibly deformable material extends - as said: in the channel space 40 - in a U-shape between two mutually parallel wall connections 52 of the pump housing 12 and its hose ends 53 each connect to an enclosed pump connection 54 within the wall connection 52.
  • This is equipped with a radial outer rib 56 which abuts on the inside of a stuffing box gland 58 screwed to the wall socket 52 and projects into the hose interior (51) with an insertion section (55) which ends near the pump wall (36).
  • the gland packing 58 holds sealing rubber-elastic packing rings 60 and a gland base ring 61 which rests against a shoulder-like gland base 62. Its distance from the inner surface 35 of the wall 36 corresponds approximately to its wall thickness y of approximately 8 mm.
  • One pump connection 54 forms the inlet connection of the hose pump 10, into which the medium to be pumped is drawn in thanks to a suction force generated by the restoring force of the pump hose 50.
  • the other pump nozzle 54 serves as a discharge for the medium being pumped.
  • the pump hose 50 is clamped directly on the wall 36 of the pump housing 12 on the inside diameter d, the shoulder-like gland 62 between this inside diameter d and a tangent Q to the inside surface 35 of the wall 36 through its intersection N with that parallel to the central axes M of the wall socket 52 Pump diameter D arranged.
  • the pump tubing 50 is clamped by means of an elastomer stuffing box 60 inside the pump housing 12, which reduces the specific clamping forces on the pump tubing 50 and also ensures its sealing against the pump housing 12.
  • 1 shows a gap 64 tapering from that gland base to the inside of the pump between the inner wall surface 35 and the pump hose 50 which is thereby sealed; the latter does not touch the pump housing 12 all around at the clamping point, which is confirmed by the distance designated 64a on the opposite hose flank in FIG. 1 and the inner diameter k of the wall socket 36; this is larger than the hose outer diameter e.
  • the wall 36 of the pump housing 12 merges into an integrally formed outer flange 37, which - with the interposition of a sealing ring 65 - has a pump cover 66 screwed to it, from which an outlet connector 68 of small diameter is formed and can be closed by a screw plug 69 with sealing ring 70 is.
  • a further axially parallel bushing 72 - compared to the outlet port 68 - of larger diameter, which projects laterally from the path of movement of the rotor wall 15 and sliding block 48 and axially with a sight glass 73 and radially with a branch 74 is equipped as a filling element.
