Definitions

  • the invention relates to a Siebrundbeschicker according to the preamble of claim 1 and a wear plate for the Ausstreicharm Siebrundbeschickers according to the preamble of claim 11.
  • a Siebrundbeschicker is used in the manufacture of clay for the preparation of clay.
  • the Siebrund feeders are used to homogenize, buffer, dose, shred and mix the clay. Often it is also possible to expose the clay in Siebrundbeschicker water vapor, which can be added through nozzles.
  • the heavy clay clay is transported from above into a sieve basket of the Siebrund feeder. Within the Siebrundbeschickers the mass is poured several meters and weighs on a Ausstreicharm the Siebrundbeschickers. The Ausstreicharm moves and mixes the heavy ceramic clay mass by rotating to the outside and presses the clay mass through a circumferential sieve of Siebkorbs.
  • the heavy ceramic clay mass is prepared for the shaping of the bricks in order to obtain an optimal quality of the bricks. Due to the direct contact with the clay mass, a very strong abrasive wear occurs at many points of the Siebrund loader. In particular, the Ausstreicharm on which a large weight loads, is exposed to this wear.
  • a replaceable wear plate is used.
  • the wear plate covers those areas of the Ausstreicharms, which face the Tonmasse in operation of the Siebrundbeschickers.
  • the spreading arm rotates around a rotation axis in a circumferential direction.
  • the Ausstreicharm has a contact surface, which is bounded by a leading edge and a trailing edge.
  • the leading edge is arranged starting from the trailing edge in the circumferential direction in front of the trailing edge, wherein the trailing edge is arranged in the direction of the axis of rotation higher than the leading edge.
  • Ausstreicharm pushes the clay mass in front of them and pushes them upwards and outwards in the direction of sieves, through which the clay mass is to be pressed.
  • the wear plate engages around the front edge of the Ausstreicharms. From the underside of the Ausstreicharms ago the wear plate is fastened in the region of the leading edge by means of screws on Ausstreicharm. When a bulge of the wear plate these screws must be solved. For this purpose, it is necessary to disassemble the Ausstreicharm at least partially, for which in turn a large part of the machine must be dismantled. This is time-consuming and costly, especially since at least two people are required to expand the Ausstreicharms.
  • the invention has the object of developing a generic Siebrundbeschicker such that a simple installation and removal of a wear plate is possible.
  • Another object of the invention is to develop a generic wear plate for the Ausstreicharm Siebrundbeschickers such that a simple assembly and easy disassembly of the wear plate on the Ausstreicharm Siebrundbeschickers are possible.
  • the wear plate in the front edge is attached exclusively by means of a positive connection between wear plate and Ausstreicharm the Ausstreicharm.
  • the wear plate is attached by means of a frictional connection on Ausstreicharm. This allows the assembly and disassembly of the wear plate in the installed state of the Ausstreicharms.
  • the Ausstreicharm must not be dismantled or raised to change the wear plate. The required in the prior art dismantling of the machine is completely eliminated.
  • the wear plate is secured in the region of the front edge by means of a positive connection and in the region of the trailing edge by means of a frictional connection, the frictional connection can be solved or opened in an easily accessible area.
  • the assembly or disassembly of the wear plate can be performed by a single person. This saves time and money.
  • the wear plate engages over the Ausstreicharm in the region of the front edge hook-shaped and is located in this area at least partially on the Ausstreicharm that characterized the positive connection is realized.
  • the wear plate comprises a front face, with which it bears against the front edge of the Ausstreicharms.
  • the front face extends in the direction of the axis of rotation.
  • the wear plate is located with a pressure plate on the contact surface of the Ausstreicharms. In the direction of the axis of rotation of the pressure plate is further down in the direction of the axis of rotation with respect to a holding surface for the positive connection with the Ausstreicharm.
  • the holding surface extends, starting from the front of the wear plate counter to the direction of rotation, so that between pressure plate, front and holding surface is formed in the direction opposite to the direction of rotation open space.
  • the Ausstreicharm is positively received in the space in the region of its front edge. In this way, the positive connection of the wear plate is realized with the Ausstreicharm in the region of the front edge of the Ausstreicharms in a simple manner.
  • the Ausstreicharm comprises a trained separately from the Ausstreicharm stop bar.
  • the stop bar is located below the front edge of the Ausstreicharms and connected to the Ausstreicharm.
  • a uniform stop for the wear plate can be formed in the region of the front edge of the Ausstreicharms.
  • the stop bar can be used to compensate for worn out areas and thus to form a precisely defined stop for a wear plate along the entire length of the front edge of the Ausstreicharms.
  • an expedient embodiment of the invention is that the Ausstreicharm for non-positive attachment of the wear plate on Ausstreicharm means of a Fastening element in the region of the trailing edge comprises an attachment point.
  • the wear plate in the region of the attachment point of the Ausstreicharms a hole through which the fastener is guided in the attachment point of the Ausstreicharms.
  • Siebrundbeschickers the fastener penetrates the attachment point completely and is freely accessible from below. This allows an attachment of the fastener without obstacles easily and quickly.
  • the attachment point is introduced into a mounting plate which extends in a plane perpendicular to the axis of rotation.
  • the fastener can be easily inserted at the trailing edge of the Ausstreicharms from above into the attachment point.
  • Another advantage of using a mounting plate is that such a mounting plate can also be subsequently attached to already put into operation Ausstreicharme for which originally no frictional attachment in the region of the trailing edge of the Ausstreicharms was provided. This can be done, for example, by welding the mounting plate to the Ausstreicharm in the region of the trailing edge.
  • Such a mounting plate may be arranged on the Ausstreicharm that it is freely accessible both from below and from above in the region of the hole.
  • a further advantageous additional or alternative embodiment of the invention is that below the attachment point a pocket is formed in the body of the Ausstreicharms, by means of which the fastener is accessible.
  • the hole of the wear plate is formed substantially circular, and the wear plate comprises means for Anti-rotation of the fastener.
  • the fastener is securely mounted when closing the frictional connection against rotational movements.
  • the fastener may be configured, for example, as a screw that does not rotate thanks to the anti-rotation means when screwing a nut on the screw. This makes a simple and comfortable closing of the frictional connection at the trailing edge of the Ausstreicharms possible.
  • the means for anti-rotation comprise a wear plate means for rotation protection.
  • the anti-rotation means comprise the projection on the fastening element.
  • the projection of the fastener engages in the recess of the hole.
  • the recess extends at the edge of the hole in the radial direction of the hole.
  • the wear plate comprises a mounting surface, in which the hole is introduced.
  • the recess at the edge of the hole is a recess in the mounting surface of the wear plate.
  • the wear plate comprises a Senklochring, through which the hole is formed. This allows the fastener to be centered in the hole.
  • the corresponding inventive wear plate for the Ausstreicharm Siebrundbeschickers has a front and a rear mounting surface.
  • the front face is in the state mounted on the Ausstreicharm wear plate in the operation of the Siebrundbeschickers starting from the mounting surface in the direction of rotation the Ausstreicharms arranged in front of the mounting surface.

Between the front and mounting surface extends a pressure plate of the wear plate.
  • the pressure plate further down in the direction of the rotation axis opposite a holding surface is arranged, which extends from the front front opposite to the direction of rotation.
  • a positive connection of the wear plate with the Ausstreicharm is formed between the pressure plate, front and holding surface in the direction opposite to the direction of rotation open space for receiving a part of the Ausstreicharms.
  • one hole or more holes are arranged exclusively on the mounting surface of the wear plate. Characterized in that only one hole or a plurality of holes are arranged on the mounting surface of the wear plate, the wear plate can be connected in a simple manner non-positively with the Ausstreicharm.
  • One or more fasteners need only be mounted in the region of the mounting surface of the wear plate. This area is easily accessible, so that easy assembly and easy disassembly of the wear plate are possible.
  • the open space of the wear plate may be formed with a form-fitting part of the Ausstreicharms. As a result, the wear plate in the region of its front can be easily connected to the Ausstreicharm in the region of the front edge of the Ausstreicharms. No adhesion is required for this.
