Definitions

  • the invention relates to a pump, in particular sludge pump, with a rotating in a housing driven rotor.
  • Concrete is usually pumped on construction sites via so-called concrete distribution booms, which are stationary or mounted on roads suitable chassis, pumped to the point of application.
  • the pumping characteristic described causes a swinging of the boom, from which arise at the end, ie at the exit point of the concrete, movements whose extent, increasing with increasing mast length, endanger the working people in this area and the introduction of the concrete to the utmost make it difficult, even impossible.
  • accelerations results mainly from the mass of the conveyed Increasing length of the delivery line increasingly increased energy consumption for the drive.
  • peristaltic pump Another type of pump used to convey such thick materials as concrete is the so-called peristaltic pump. It is characterized by a simple, rotationally continuous drive. Due to the design results for the peristaltic pump a considerably lower discontinuity in the promotion than in the previously described piston pump. However, their use is limited to comparatively low discharge pressures (up to 30 bar), which severely restricts their use in the pumping of thick materials.
  • the EP 0 799 996 shows a pump in the manner of a Wankel engine with a rotary piston.
  • two suction openings and two discharge openings are provided on the circumference of a trochoidal housing having at the narrowest point stationary sealing or separating strips to separate the suction from the discharge openings.
  • the rotary piston in this case has a curved outer surface to ensure the required seal. As a result, however, the production is complicated, especially since the stationary sealing strips are required, which are also exposed to high wear.
  • the invention is based on the object, a new positive displacement pump, in particular for use as a slurry pump for pumping non-homogeneous, abrasive media such.
  • a new positive displacement pump in particular for use as a slurry pump for pumping non-homogeneous, abrasive media such.
  • the designed as a prism-like body rotor in which at least the connecting lines of the corners of the bases form an equilateral polygon, generated with its longitudinal edges during its rotation about its, simultaneously moved on a circular path center axis, the longitudinal inner wall surface of the housing.
  • the rotor whose center axis passes through a full circle, must be rotated about the central angle of the equilateral polygon formed by the connecting straight lines of the corners of the base areas of the prismatic body. It follows that the shape of the longitudinal inner wall surface of the housing is determined by the number of longitudinal edges of the prismatic body.
  • the circular motion of the center axis of the rotor is generated by its storage on the eccentric of the, mounted in the end walls of the housing, driven eccentric shaft.
  • the rotation of the rotor about its center axis according to the described regularity can be enforced with various gears.
  • the location of the feed and discharge ports, in conjunction with the length of the prismatic body, determines the geometric displacement of the pump. Therefore, in order to obtain the largest possible flow rate, it is necessary to set the position of the supply and discharge openings so that the value for the geometric displacement becomes maximum.
  • a feed container angeaut.sein wherein the sludge pump is arranged so that their feed opening (s) in the feed container are below the lowest level of the filled conveyed.
  • a preferably cylindrical intermediate wall Arranged in the rotor, preferably on the center axis thereof, is a preferably cylindrical intermediate wall which radially surrounds the gear described and which extends to the inner wall surfaces of the two end walls of the housing. It is advantageous to determine the radial position of the intermediate wall in connection with the determination of the rotor dimensions so that the swept from the end faces of the intermediate wall surfaces outside of the end faces of the, the longitudinal outer wall surfaces of the prismatic body forming outer walls of the rotor swept Areas lie.
  • the space formed by the long-side inner wall surfaces of the outer walls of the prism-like body and the long-side outer wall surfaces of the intermediate wall in communication with the inner wall surfaces of the two end walls of the housing is provided as a washing chamber.
  • the supply and removal of the rinsing liquid can be done either via the frontal walls of the housing or over, through the eccentric shaft and the rotor leading lines.
  • the rubber-elastic elements are preferably vulcanized or glued.
  • the size of the connecting surfaces is increased by the fact that the rubber-elastic elements extend beyond the end faces on the longitudinal outer wall surfaces of the outer walls of the prismatic body.
  • this eliminates a high wear resistance of the longitudinal outer wall surfaces of the metallic outer walls.
  • sealing strips separate by their constant contact with the longitudinal inner wall surface of the housing, the pumping chambers from each other or seal against each other.
  • the sealing strips are preferably held interchangeably on the longitudinal edges of the prismatic body. They are made of highly wear-resistant and hard material, as they also run over the feed and discharge openings on the longitudinal inner wall surface of the housing with their end faces and thereby cut through the fluid.
  • the weather strips may be received and held in a groove machined in the longitudinal edges of the prismatic body.
  • the longitudinal edges of the prismatic body additionally mutually incorporated and filled with vulcanized or glued rubber elastic material recesses may be present, so that when they are acted upon by the pressure of the pumped medium held in the grooves incorporated sealing strips are pressure-dependent pressed against the longitudinal side inner wall surface of the housing ,
  • the sealed spaces facing sides of the sealing elements are expediently equipped with very good wiping action, so that on the inner wall surfaces of the frontal walls of the housing adhering fine-grained and abrasive particles are reliably stripped off.
  • the longitudinal outer walls of the prism-like body are formed by a plurality of, preferably identical, individual elements, which are releasably secured to a base body, which is composed of the other elements of the rotor.
  • the longitudinal outer walls of the prism-like body are formed by an undivided element, which is releasably secured to a base body composed of the remaining elements of the rotor.
  • the longitudinal outer walls of the prismatic body no separation points are present, which complicate the seal between the delivery chambers and the interior of the rotor. Furthermore, a simpler assembly of the rotor is given by the one-piece element.
  • the inner wall surface of the longitudinal housing wall is formed wear-resistant and / or equipped with a wear-resistant coating, so that the removal in the promotion of abrasive media such. B. concrete is kept as low as possible.
  • On the inner sides of the two end walls of the housing releasably secured plates are provided, at least in the area of swept by the front-side sealing elements and guide elements of the rotor surfaces.
  • the inside surfaces of the plates serve as a mating surface for the sealing elements and guide elements of the rotor and at the same time form the frontal boundaries of the constantly changing delivery chambers and the rinsing chamber. This requires a very smooth and wear-resistant surface, which is preferably produced by a coating, in particular by hard chrome plating.
  • the pump housing is formed from a longitudinal wall and two detachably connected end walls.
  • the shape of the inner surface of the longitudinal housing wall results from the path of the longitudinal edges of the prismatic body during its movement in accordance with the described regularity.
  • the supply and discharge openings for the conveyed material are arranged.
  • the front-side housing walls are preferably screwed via a flange with the longitudinal housing wall.
  • the bearings for the eccentric shaft are arranged in the center of the frontal housing walls.
  • the diameter of the eccentric is expediently made larger than the, increased by twice the amount of eccentricity, the largest shaft diameter.
  • the bearings and the gear teeth, as well as the front-side sealing elements and guide elements on the rotor are supplied to minimize the wear of at least one central lubrication system with lubricants.
