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 To avoid that the container attachment is damaged by a collision with the approaching truck mixer, 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. Also from the WO 03/042535 A a material supply container of the type mentioned is known.
  • 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 invention is based on the idea to make the interior of the material feed container for maintenance personnel easier to access by the front wall side has an easily removable and removable container attachment.
  • 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 first edge part located on the container attachment is aligned with the second edge part belonging to the container lower part.
  • the material feed opening can then be covered in a simple manner by a hinged lid hinged to the container attachment on the upper end wall part.
  • the hinged lid is preferably made of plastic, so that concrete residues adhere to it worse than on a metal lid.
  • the hinged lid is easier to clean.
  • the container lower part expediently has a rear wall, a bottom, a lower end wall section and lower lower wall sections sloping towards the lower end wall section.
  • the upper end wall part and the upper side wall parts the container top advantageously carry at its lower edge a first flange, which is releasably connected to a complementary second flange on the lower end wall portion and the lower side wall portions of the container base. Between the first flange and the second flange a sealing means is expediently arranged. This results in a good sealing effect at the dividing line between the container base and container attachment.
  • the lower end wall portion, the rear wall, the lower side wall portions of the container base and / or the bottom expediently consist of sheet metal, preferably of stable sheet steel.
  • the lower end wall part, the rear wall, the lower side wall parts and / or the bottom at least partially made of a 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, preferably with titanium components.
  • the lightweight material carries an abrasion-resistant and / or hard coating, in particular from the material group chromium, silicon carbide or ceramic.
  • the delivery cylinder openings are preferably arranged in the lower end wall part.
  • a support device for the transfer tube is preferably mounted in the container lower part.
  • the container base expediently pivot bearing for a stirrer.
  • the upper end wall portion and the upper side wall portions of the container top can also be made of sheet metal, preferably made of sheet steel. In this case, smaller wall thicknesses are possible than in the sheet metal of the container base. However, it is preferred that the upper end wall portion and the upper side wall portions are made of plastic.
  • the container attachment is made in one piece as an injection molded part. At this injection molded part expediently a container bead facing support bead is formed for a grid. Likewise, reinforcing strips can be integrally formed on the upper end wall part and / or on the upper side wall parts, which give the container top a higher stability.
  • the container attachment in this case in particular the upper end wall portion and / or the upper side wall portions, at least partially made of a lightweight material.
  • the lightweight material used for this purpose may expediently have 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, which preferably comprises titanium components.
  • the lightweight material carries an abrasion-resistant and / or hard coating, in particular from the material group chromium, silicon carbide or ceramic.
  • the container base may have over the lower end wall portion projecting support elements for a grid. This is especially advantageous when the grid is very heavy and its weight can not be carried by the container attachment.
  • the second, back wall-side edge part of the material feed opening is expediently formed by a rubber apron attached to the container bottom part. This adjoins the rear wall and on the rear wall outgoing sections of the side walls.
  • the container base and the container attachment are connected by screws. This results in a simple, stable and yet easily detachable connection.
  • the advantageous embodiment according to claim 29 is based on the idea that a hinged lid covering the material supply opening hinged to a container wall made of plastic or a lightweight material is easier to clean than a conventional hinged lid made of sheet metal. 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 first plastic shell may have a smooth surface facing the material supply opening.
  • the second plastic shell has stiffening beads. This gives the hinged lid increased stability.
  • the hinged lid is advantageously made in one piece by a Rotationsg tell Kunststoff.
  • the hinged lid at least partially made of a lightweight material, this may expediently have a carbon fiber reinforced plastic and / or a glass fiber reinforced plastic.
  • the lightweight material may also be silicon carbide or a metal foam, preferably having titanium components.
  • the lightweight material carries an abrasion-resistant and / or hard coating, in particular from the material group chromium, silicon carbide or ceramic.
  • the hinged lid expediently has handles, which are preferably integrally formed. Furthermore, it expediently hooks are hooked into the attached to a container wall closure elements can.
  • the hooks are preferably integrally formed on the hinged lid.
  • the hinged lid is preferably connected by at least one hinge and at least one gas spring with the container end wall. The gas spring facilitates the opening of the lid. Near its side connected to the container end wall, the hinged lid on the first plastic shell expedient attachment means for a rubber apron. This hangs down from the hinged lid into the material feed opening and prevents thick material from flowing into the gap between the hinged lid and the container end wall.
  • the advantageous development according to claim 42 is based on the idea that it requires less effort to mount the intermediate rings on the inside of the container and 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 the 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. This allows delivery cylinder different inner diameter of the material feed container be connected by different spacers are inserted into the delivery cylinder openings.
  • the flow passages 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.
