Definitions

  • the invention relates to a container, in particular a fermenter for fermenting biodegradable substances, comprising at least one bottom and at least one wall, an interior of the container being enclosed by means of the bottom and the wall, the container having at least one stirrer projecting into the interior, which is held in an installed position on an upper bearing and a lower bearing, the agitator comprising a rotatable shaft which can be driven by means of a drive device and on which at least one stirring element which is rotatable together with the shaft is arranged, by means of which substances located in the interior of the container can be stirred , wherein the lower bearing is arranged on the bottom of the container and a bearing device located at a lower end of the shaft can be supported in the lower bearing, the shaft having a longitudinal axis which, in the installed position, has an angle of between 5 ° and 60 with respect to the vertical ° includes.
  • the invention further relates to a method for installing an agitator in a container according to the preamble of claim 9.
  • Containers of the type described at the outset such as fermenters, have been known for some time according to the prior art and are used primarily in the field of biogas plants which are used to generate regenerative energy.
  • Containers with obliquely arranged agitators have the advantage that the substrate in the container is mixed both in the horizontal and in the vertical direction, so that undesired separation of the substrate, which inhibits the fermentation process, into individual layers is prevented.
  • Agitators are subject to a certain amount of normal wear during operation, which primarily affects the bearings and gearbox of the agitators. Depending on the quality of the agitator, sooner or later it will fail due to a failure of at least one of the wearing parts. These must then be changed in order to be able to put the agitator back into operation. With fermenters with several agitators, a temporary failure of a single agitator is sometimes tolerable for a certain time. Due to the decreasing circulation of the substrate in the fermenter, however, the desired biological slows down
  • DE 10 2004 027 077 A1 discloses an agitator for a fermenter with an inclined shaft, in which the shaft should be heatable. To support the shaft, it has a flexible upper shaft bearing, which is located in an upper area of the fermenter wall, and a lower shaft bearing, which is variable during installation with respect to the angle of attack and can be swiveled against a mounting bracket in order to assemble the shaft
  • a disadvantage of the known agitator is that the entire filling level of the fermenter is not available during operation, since the fermenter can only be filled up to the upper shaft bearing.
  • the flexible shaft bearings are also prone to failure.
  • Another agitator with an inclined shaft of the agitator can be found in DE 10 2013 219 938 A1.
  • the agitator described is characterized in that the upper bearing of the shaft takes place on an upper side of the fermenter wall.
  • it is transferred from a vertical orientation to an inclined operating position by moving a bearing located at a lower end of the shaft along a guide device which is located on the bottom of the fermenter.
  • a lower end of the shaft is in a bottom bearing and an upper end of the shaft is in a side next to the
  • the agitator paddles can be transferred from a working position in which they are spread apart with respect to the longitudinal axis of the shaft into an assembly position which they are folded towards the agitator shaft, which significantly reduces the outer diameter of the entire agitator.
  • the paddles are fixed or released in or out of the operating position with the aid of an actuating device which is arranged at the upper end of the shaft and with which a push rod can be actuated which extends up to the paddle attachment points.
  • the actuator for paddle fixation complicates the
  • Container wall or other storage facilities must be avoided.
  • Agitator which is mounted on an upper bearing bracket outside the container and a lower bearing bracket inside the liquid in the container. Both when disassembling and when assembling the agitator, the lower end of the shaft is coupled to a search hook or search ring, which in turn is connected to a rope which leads out of the container through an opening arranged above the base bearing and can thus be manipulated.
  • the opening in the container ceiling thus serves to find the correct position for the lower shaft end when it is inserted into the bottom bearing.
  • the underlying task is based on a container at the beginning
  • a guide device arranged on an upper side of the container, which has a contact surface for at least a section of the shaft, the agitator being able to be aligned by means of the shaft along the contact surface with a lower end of the shaft onto the lower bearing and in an aligned state can be guided into the installation position.
  • Application includes an area of the container that is free of a substance in the container, such as an upper area or upper portion of the wall or an area of a container ceiling, e.g. one made of concrete.

  • Installation position can be achieved even if the container is filled and the view of the lower bearing is blocked.
  • the guide device can, for example, on the wall of the container be positioned and specify a movement of the agitator in different ways. The movement can take place in a direct way to the lower bearing, that is to say it can be straight, or it can also run straight in sections or specify a curved path.
  • a comfortable or convenient installation of a new or repaired agitator is possible for the mechanic or installers, even when the container is full, in particular since the agitator can be aligned and inserted from outside the container.
  • An aligned state of the shaft or of the agitator is preferably to be understood as a position in which a longitudinal axis of the shaft coincides with a fixed axis of the lower bearing. Only by moving the agitator or the shaft axially at least at the end of the assembly movement
  • An upper section of the shaft itself which is free of stirring elements, can serve as the section of the shaft that is guided on the contact surface of the guide device. Accordingly, it is conceivable that the agitator is first let into the container without contacting the guide device and that the shaft does not come into contact with the guide device until all the stirring elements are already in the interior of the container. Correct alignment of the shaft only in the last section of the insertion path is sufficient to hit the lower bearing and to move the agitator into the correct installation position.

  • the handling of the agitator to be used is thus significantly simplified.
  • the extension can be removed from the shaft. In this way the extension during operation of the agitator, for example, does not protrude over an upper edge of the container, which can be advantageous for reasons of space.
  • the removed extension can also be used to install another agitator.
  • the shaft including the extension connected therewith, protrudes in its installation position over an upper edge of the wall, a section of the wall projecting beyond the wall
  • “Extended” shaft has a length of at least 1 m, preferably at least 2 m. The longer the shaft (typically between approx. 4 m and 11 m), the longer the extension should also be, in order to have a sufficient torque in the outside of the container
  • the section of the shaft which is free of stirring elements is longer by the amount than in conventional agitators which corresponds to the projecting section of the shaft. This has the advantage that the shaft can be guided over an extended length along the guide device, which is the
  • the guide device can, for example, comprise a pipe cut in the longitudinal direction, the inside diameter of which corresponds to the outside diameter of the shaft or the extension connected with it, the contact surface forming a partial circle.

  • the ceiling device is designed as a concrete ceiling, there is the advantage that the guide device can be positioned on the concrete ceiling and thus
  • Agitators can also be arranged in a central area of the container.
  • a concrete ceiling offers numerous possibilities to set up and anchor the guide device in a stable manner, so that forces generated when guiding the agitator to be used are introduced into the concrete ceiling.

  • Guide device is detachably connected to the container. After installation of an agitator, the guide device can thus be removed and the drive device, comprising a motor and a gear, can be mounted on the agitator. Because the guide device can be removed, there is no competing space requirement for the guide device and drive device.
  • the guide device has at least two fixing elements for fixing the at least one section of the shaft to the guide device, the fixing elements allowing a relative displacement between the contact surface and the shaft, and preferably the shaft in its fixed state being aligned with the contact surface . Accordingly, the shaft can be slidably fixed to the guide device after being brought into contact with the latter. Manual holding of the shaft on the guide device is therefore unnecessary.
