Definitions

  • the invention relates to a material feed container for a slurry pump according to the preamble of claim 1.
  • a material feed container for thick matter pumps which has an upwardly open container bottom part and a container attachment releasably connected thereto via a flange connection.
  • the peripheral upper edge of the container attachment limits the material feed opening.
  • an agitator is mounted, the bearings are in an open-edged recess of the container base, so that the agitator is easily replaceable after removal of the container attachment.
  • the container attachment forms a hopper for thick matter, such as concrete.
  • the filling of the concrete is usually carried out in that a truck mixer approaches the material supply container and fills the concrete via a channel in the material supply container.
  • the container attachment must be made of sturdy sheet metal. This requires a high weight, so that the container attachment can not be easily removed by hand.
  • Material feed container according to EP 1 076 596 B1 have in the delivery cylinder openings intermediate rings as wearing parts that protect the belonging to the container end wall inner surface of the delivery cylinder opening from wear by flowing concrete. These intermediate rings must be replaced regularly due to wear. Since the intermediate rings are inserted from the delivery cylinder side into the delivery cylinder opening, the delivery cylinder must first be removed from the container end wall for mounting and dismounting. This is expensive.
  • the solution according to the invention is based on the idea that it requires less effort to mount the intermediate rings on the inside of the container and to dismantle as over the container outside. This avoids that when replacing the intermediate rings, the delivery cylinder must be disconnected from the material supply container.
  • An intermediate ring is inserted into the delivery cylinder opening via the interior of the container by pushing the cam on its outer lateral surface into the bayonet opening and subsequently rotating the intermediate ring about its longitudinal axis, so that the cam is inserted into the inner groove.
  • the mounting of an intermediate ring on the container interior is particularly advantageous when the material feed container, as described above, is formed in two parts. By removing the relatively light container top the inside of the container is easily accessible.
  • the inner groove may be formed circumferentially in the delivery cylinder opening.
  • the intermediate ring carries on its outer circumferential surface at least two, preferably three equally spaced angularly arranged cams.
  • the delivery cylinder opening then has a number of cam corresponding number of bayonet openings, which are also arranged at the same angular distance from each other. Since the intermediate ring is fixed in the axial direction by the engagement of the cams in the inner groove, this fixation is more stable, the more cams are arranged on the outer lateral surface.
  • a connection plate for connecting delivery cylinders is attached to the container outside of the container end wall, through which extend the delivery cylinder openings.
  • a spectacle plate having two spectacle plate openings is expediently releasably attached to the inner surface of the container end wall.
  • the spectacle plate openings communicate with the delivery cylinder openings, and their boundary surfaces are aligned with the boundary surfaces of the flow passages in the intermediate rings.
  • the spectacle plate thus covers a part of the delivery cylinder openings and additionally fixes the intermediate rings in the direction of the container interior. To replace the intermediate rings, the spectacle plate is removed.
  • the intermediate ring and / or the spectacle plate expediently consist at least partially of a wear-resistant lightweight material.
  • the lightweight material may comprise a carbon fiber reinforced plastic and / or a glass fiber reinforced plastic. It is also possible that the lightweight material is silicon carbide or a metal foam, the latter preferably having titanium constituents.
  • the boundary surfaces of the flow channels and / or the spectacle plate openings are coated with a wear layer.
  • a wear layer This preferably consists of a hard metal or of a material of the material group chromium, silicon carbide or ceramic.
  • the spectacle plate and the intermediate rings, which are each wearing parts, are protected by the wear layer against wear and must therefore be replaced less frequently.
  • the diameter of the flow channel tapers towards the container interior or towards the delivery cylinder.
  • delivery cylinders of different inner diameters can be connected to the material supply container by using different intermediate rings in the delivery cylinder openings.
  • the flow channels are expediently dimensioned so that their boundary surfaces are aligned with the inner surfaces of the delivery cylinder.
  • the intermediate ring in its lateral surface at least one axially opposite the cam offset circumferential groove with a sealing ring for engagement with the container end wall and / or the connection plate.
  • it has two circumferential grooves, one of which receives one against the container end wall, the other one applied to the connection plate sealing ring.
  • the intermediate ring may have on one of the spectacle plate facing end face a further circumferential groove with a voltage applied to the spectacle plate sealing ring.
  • the intermediate ring may have recesses for inserting holding thorns on an end face facing the spectacle plate. Furthermore, between the intermediate ring and the container end wall, a circumferential cavity can be arranged, which can be filled with lubricant via a feed opening and which increases when the intermediate ring is withdrawn from the delivery cylinder opening.
  • a mounting ring is used with holding thorns, which engage in the recesses of the intermediate ring. With the help of the mounting ring of the intermediate ring is rotated to solve the bayonet closure. Subsequently, a lubricant, such as grease, is pressed into the cavity, so that the intermediate ring is pressed out of the delivery cylinder opening, wherein the cams are moved through the bayonet openings.
  • the advantageous development according to claim 17 is based on the idea that a material supply opening covering, hinged to a container wall hinged lid made of plastic or a lightweight material is easier to clean than a conventional hinged lid Sheet. Thick material, especially concrete, adheres much less to plastic than to sheet metal.
  • the hinged lid is expediently designed as a hollow plastic body with a first plastic shell facing the material feed opening and a second plastic shell preferably connected in one piece with the latter, forming a top side of the lid.
  • a plastic hollow body is relatively stable with low weight. This is particularly advantageous when the hinged lid is hinged to the container attachment and must be removed together with the container attachment for maintenance work inside the container.
  • the advantageous development according to claim 18 is based on the idea to make the interior of the material feed container for maintenance personnel more accessible by having an easily demountable and detachable container attachment on the end wall side.
  • the container top does not extend to the rear wall which faces the approaching truck mixer.
  • the peripheral edge delimiting the material feed opening has, on the rear wall side, an edge part belonging to the container lower part.
  • the container attachment is thus protected against damage by the truck mixer. It must therefore not be designed as stable as the container base and can have a relatively low weight.

  • the two flanges 50, 60 are connected in a simple manner by means of screws 62. Between them, a rubber seal can be arranged so that the container base 38 and container attachment 40 can be assembled in a simple manner to the material supply container 20.
  • the material supply container 20 has an upwardly facing material feed opening 64, which is delimited by a peripheral edge 66, 68.
  • the peripheral edge is divided into two edge parts 66, 68.
  • the first edge portion 66 is formed by the upper edge of the upper end wall portion 44 and the upper side wall portions 46. It is followed by the second edge part 68, which is formed by the upper edge of a rubber apron 70. This is attached to the container base 38 and protrudes beyond the rear wall 28 and extending from the rear wall 28 away portions of the lower side wall portions 58 out.
  • the two edge parts 66, 68 are aligned.
  • the container base 38 In the container base 38 bearing openings 72 are arranged in the side walls 42, which serve to receive bearings of a stirrer. In the rear wall 28, a rear wall opening 73 is arranged, via which the pipe switch 34 can be connected to the discharge nozzle 30. In the lower end wall portion 56 are the delivery cylinder openings 24 for connecting the delivery cylinder 26.
  • the container base 38 is made of sturdy, thick-walled sheet steel. On the container top 40 only forces that originate from the filled into the material supply port 64 concrete act. Its stability is therefore much lower requirements.
  • the container base 38 has over the lower end wall portion 56 projecting tubular support elements 74 for a grid.
