Definitions

  • the present invention relates to a press screw separator for separating solid components from a slurry containing solid and liquid components.
  • Press screw separators are used to press out a slurry.
  • the turbidity can in particular be manure or wastewater.
  • the wastewater can come from agricultural, municipal and industrial facilities, but these should always be separated into solid and liquid components.
  • precipitants or flocculants to the pulp before pressing it out.
  • a cylindrical sieve is usually arranged in the housing of the press screw separators, within which a clearing element rotates. Using the clearing element, the pulp is conveyed and pressed through the press screw separator. The liquid portions of the slurry pass through the sieve, while a solid plug forms within the sieve.
  • the rotating clearing element transports the solid plug to one end of the press screw separator in order to be ejected there. The torque is transferred from the clearing element to the sieve via the solid plug. Therefore, the sieve must be arranged in the housing so that it cannot rotate.
  • EP 2 938 418 B1 describes a press screw separator with a frame fastened in the housing of the press screw separator, in which part of the sieve area is mounted. This frame supports the screen and prevents the screen from failing. With this solution, it is disadvantageous in terms of manufacturing costs and maintenance that the frame requires an additional component in the housing.
  • DE 202011105765 Ul shows a sieve arrangement for a press screw separator, comprising a rigid, hollow cylindrical jacket and a hollow cylindrical sieve resting on the inner surface of the jacket. There are holding rods attached to the outside of the jacket. The sieve arrangement is mounted and fixed in the press screw separator with these holding rods. Further relevant prior art is shown in DE 102011080865 Al.
  • the task is to create a technically simple press screw separator of the type mentioned at the beginning, which is simple and Cost-effective production enables safe, reliable and low-maintenance operation.
  • a press screw separator for separating solid components from a slurry containing solid and liquid components, comprising a housing, a cylindrical sieve which is arranged in the housing, and a clearing element which is arranged within the sieve and is rotatably mounted about a longitudinal axis of the sieve Squeezing out the slurry, the housing comprising a first housing part and a second housing part, a first sieve area of the sieve being mounted in a rotationally fixed manner in the first housing part, and a second sieve area of the sieve being mounted without play in the second housing part and directly contacting the second housing part.
  • a press screw separator which comprises a housing in which a sieve is mounted.
  • this housing absorbs all radial and axial forces that occur during operation.
  • the press screw separator according to the invention usually comprises a cover surrounding the housing in order to concentrate and discharge the liquid phase after separation. This cover can be quickly and easily removed for maintenance work.
  • the press screw separator according to the invention comprises a clearing element for pressing out the pulp, which is arranged within the sieve and is rotatably mounted about a longitudinal axis of the sieve.
  • the sieve is therefore usually cylindrical, with the housing also preferably being cylindrical. As a load-bearing component, this housing absorbs all radial and axial forces that occur during operation.
  • the housing according to the invention therefore enables, in addition to the task of absorbing all other radial and axial forces, also a supporting function of a sieve area against the bursting pressure prevailing in this sieve area, so that the sieve can absorb significantly higher forces than would be the case without the supporting function of the housing.
  • a first sieve area of the sieve is mounted in the housing in a rotationally fixed manner, while a second sieve area of the sieve is mounted in the housing without play.
  • the arrangement according to the invention therefore allows the reinforcing second region of the housing to be provided only at those points of the screen where particularly high forces occur and which are therefore potential points of failure.
  • the first sieve area which is not supported by the housing, can also be mounted very easily in a rotationally fixed manner in the housing. This means that the housing can support the sieve in the second sieve area, so that there are no problems here Deformation and therefore no failure of the sieve is possible.
  • the second sieve area is in particular the area of the sieve in which the highest dry substance contents occur within the press screw separator. This means that in the second sieve area the sludge is largely separated into its solid and liquid components and the plug is formed. In other words, the second sieve area lies behind the first sieve area in the conveying direction of the clearing element.
  • the solution according to the invention differs from EP 2 938 418 B1 in that a two-part housing is provided, so that no separate frame has to be inserted into the housing.
  • the second sieve area is therefore not connected to a separate frame, but rather directly to the second housing part, which means that there is no need for a frame that would have to be inserted into the housing.
  • the second housing part which connects to the first housing part in the longitudinal direction of the sieve.
  • the advantage is achieved that part of the sieve can be stored in a rotationally fixed manner and part can be stored without play.
  • the sieve preferably has a plurality of bars which are oriented parallel to the longitudinal axis.
  • Such bar sieves have advantageous properties when used in press screw separators, since in particular there are no elements running in the circumferential direction that could be damaged by the solid plug conveyed by the clearing element.
  • the supporting second region of the housing comprises support rings that are normal to the axis of rotation.
  • This has the advantage that only the supporting bars of the sieve are covered by the supporting housing.
  • a rolled-up elongated sheet metal or a rolled-up perforated sheet could also be used, with the support rings being advantageous over such solutions because they do not cover any parts of the open screen surface.
  • the supporting area of the housing has at least one reinforcing strip which extends parallel to the longitudinal axis.
  • drill holes, threaded holes and/or threaded rods are provided in the reinforcing strip, by means of which a retaining strip can be screwed to the housing.
  • the reinforcement bar allows the frame to be very to be rigid, which in particular prevents deformation of the sieve including the housing.
  • the second sieve area advantageously has a recess in the direction of the longitudinal axis.
  • a nose of the housing can preferably engage in this recess in order to prevent rotation of the second sieve area about the longitudinal axis relative to the housing. Since, as described at the beginning, the rotation of the clearing element is transferred to the sieve, torsion within the sieve can be prevented in this way. It is therefore possible to keep unnecessary tension away from the screen.
  • the nose can be designed to store the sieve within the housing. Alternatively or additionally, the nose can be designed to tension the sieve within the housing. This can be done in particular by the sieve having a cylindrical base body, with a slot parallel to the longitudinal axis over the entire lateral surface. Therefore, a nose engaging the slot having a larger dimension than the slot can increase the outer diameter of the screen, thereby forcing the screen into the frame.
  • the housing has a retaining strip that can be connected to the rest of the housing.
  • the retaining strip can be screwed to the housing.
  • the nose of the housing can preferably be formed in this way. This has the advantage that the nose of the housing is removable, which makes it easier, for example, to install and/or remove the sieve.
  • the second sieve area occupies a proportion of up to 30%, in particular up to 50%, of the sieve.
  • the highest forces within the press screw separator occur within the second sieve area. Therefore, according to the invention, the second sieve area must be selected according to the values mentioned in order to ensure that failure of the sieve due to the occurrence of excessive forces is excluded.
  • the press screw separator comprises an inlet housing on which the housing is mounted on one side to absorb torques of the clearing element.
  • the housing is therefore only supported on one side and stands freely on the side facing away from the inlet housing.
  • the first housing part comprises at least two rods which support both the first sieve area and the second housing part.
  • the rods can therefore preferably be between the Inlet housing and the second housing part extend, the first sieve area being able to be mounted on these rods at the same time.
  • the first housing part has no further elements in the circumferential direction in the area of the rods in order to enable deformation of the first sieve region.
  • the press screw separator can comprise a cover which is arranged around the housing or under the housing in order to collect the slurry that has passed through the housing.
  • the housing can thus be provided to absorb the torque without having to take on the function of collecting the separated liquid, which can take place through the cover, which in turn does not have to absorb the torque of the clearing element. What is particularly advantageous here is that there is more space available for additional components between the housing and the cover.
  • a washing device can be arranged in this space gained between the housing and the cover, which preferably comprises a washing ring driven by a linear drive and arranged around the housing. Using spray nozzles on the washing ring, a large part of the sieve can be washed without having to remove the sieve from the press screw separator.

Both the first housing area 20 and the second housing area 21 are usually designed to be essentially cylindrical and can each with a longitudinal axis exhibit. To form the housing 2, the two housing regions 20, 21 are lined up along the longitudinal axes to form a substantially cylindrical housing 2. In order to connect the two housing parts 20, 21 to one another, a flange connection is preferably used as shown in Figure 1, although another type of connection such as a welded connection or a slip connection can also be used.

  • the second sieve area 42 and the second housing area 21 are arranged directly in front of an outlet 22 of the housing 2, since the highest forces act on the sieve 4 here. This results from the fact that the slurry is compacted across the longitudinal axis 6, i.e. in the conveying direction of the clearing element 3, with liquid components constantly passing through the sieve 4 and the solid components of the slurry remaining within the sieve 4.
