Definitions

  • the invention relates to a method for determining and Use of the filling quantities of pressed material in the solid-liquid separation with a filter press comprising one Press room in which liquid under the influence of a press element acted upon by compressive force several successive lifting operations from the pressed material is squeezed, whereby in the course of a filling phase of Separation process in each lifting a quantity in the Press room is introduced.
  • Prefill quantity The same conditions apply here as with the total filling quantity. Too small or too big The prefill quantity influences the yield / performance behavior very negative.
  • the invention is therefore based on the object specified problems through an optimized procedure for Determination and use of the filling quantities of pressed material at to fix a filter press.
  • this object is achieved achieved through the following steps: 1) it is under measurement a filling and pressing process of performance and yield executed, which in the yield / performance diagram a first operating point with known performance and Yield leads; 2) for at least one subsequent one second filling and pressing process, which in the yield / performance diagram leads to a second working point at least one process variable for the second operating point set and then using relationships for the changes in performance and yield of solid-liquid separation in the filling and pressing processes under Interposition of a fictitious working point Filling quantity determined and used, which is required so that a maximum product of Yield and performance results, the transition from the first Working point to the fictitious working point by a pure Filling takes place and the transition from fictional Working point to the second working point by a pure one Pressing takes place and it is assumed that the rectilinear connections of those working points which differ by a pure pressing process, differ in Yield / performance diagram in a common Working point with maximum yield and vanishing Cut power or are parallel to each other.
  • Fig. 1 shows schematically a horizontal Filter piston press of known type. It comprises one Press cover 11 is located inside the press cover 11 a plunger 6, which is attached to a piston rod 14 is.
  • the piston rod 14 is in a hydraulic Cylinder movably supported and leads over the plunger 6 the pressing operations.
  • the press jacket 11 is about a closable filling opening by means of a pump 8 the pressed material 7 introduced, which a variety of not penetrates with drainage elements shown.
  • the drainage elements guide the liquid during the pressing process Phase of the material to be pressed 7 under the pressure of Press plunger 6 into a drain line 10 to the outside.
  • a drain line 10 to the outside.
  • At the pressed material can be fruit and the liquid phase around fruit juice.
  • the "priming" process ends as soon as the Press plunger 6 no longer at position HS reached. Then in a subsequent step only filled in discontinuous phases, each start withdrawing the plunger 6. It is first ensured by a filling control that the Press plunger 6 always the same for each lifting operation HS lying end position reached.
  • the plunger 6 also reaches progressive filling of the press room positions which move further and further away from HS.
  • the Filling control for every lifting and pressing process the yield or the performance of the pressing process constant remains. Reaches the plunger 6 during its advance the position HE, so in a subsequent step then back to the constant end position of the plunger 6 driven until the desired total amount of Press material is filled and the other press strokes only still take place without filling processes F.
  • Fig. 2 shows in a representation similar to Fig. 1, in which same reference number on same functions indicate separate filling and pressing processes.
  • An operating point denoted by 1 in FIG. 3 corresponds a current operating state of the press, like him within a sequence of individual pressings of FIG. 1 and 2 described type immediately after the end of a Lifting process occurs.
  • the plunger 6 is at Working point 1 is still in the pressing position, the working pressure but has already been dismantled. The previous one The lifting process started at operating point 1 '.
  • the working points 1 ', 1 differ only in this lifting process. If you carry out a certain filling quantity in working point 1 Pressed material too, so working point 1 goes into one Working point 3 'above, the power L increases and the yield A decreases.
  • Working points 1, 3 ' differ only in this filling process.
  • FIG. 4 shows a straight course of the pressing characteristics in the Course of several pure pressing processes. It has Pressed material due to a low total filling quantity Condition a). In comparison, for a state b) the Pressed goods with a larger total filling quantity in the final state another straight line.
  • the extended courses a) and b) run through one under idealized conditions common intersection A0 with the yield axis, corresponding to a performance value of zero. In practice it can this intersection A0 its location during processing change a batch of pressed material.
  • Fig. 5 shows the power yield comparative Combinations with different regulations of the Press operations can be achieved.
  • R1 Pre-filling process
  • L constant power L
  • Yield A shows the pressing process R2 a regulation with the The goal is constant performance with almost sufficient Refill performance.
  • R3 a pressing process without refill.
  • the course b shows a pressing process with insufficient refill performance.
  • the course a finally shows three parts, which one after the other constant end position of the pressing element for everyone Press stroke, with constant yield and finally after End of filling.
  • Fig. 7 shows the course in the yield / performance diagram a single pressing process, in which between the Working points 1 at the beginning and 4 at the end quantity of pressed material supplied is determined so that the Yield is kept constant. Another one Pressability of the goods can also be a point 4 result in greater power to the right of point 1.
  • FIG. 8 shows the course in the yield / performance diagram a pressing process in which during a Pre-fill R1 and several piston strokes comprehensive pre-pressing process is no longer refilled. This process was described in relation to FIG. 2. To the Prepress closes a non-pressing Refill process that leads from point 4 to point 3 '. At the transition from point 3 'to point 4' follow again several pressing processes without refilling. The one for the pressure-free refilling process is used working time through a transition to a virtual working point 1 ' shown.
  • Fig. 9 shows how in the yield / performance diagram of the Influence of a refill quantity supplied by a theoretical consideration can be captured. Similar to already described for FIG. 3, corresponds to the operating point 1 the current operating status immediately after the end of a single previous press stroke. The plunger 6 (Fig. 1) is still in the pressing position HS, the pressing pressure but already dismantled. Due to the refill quantity Press residues are diluted and the yield is reduced. In a virtually no time consumption through pure filling If you reach point 2, the yield will decrease, while performance remains the same.
  • G1 denotes the quantity of pressed material supplied up to point 1
  • G2 the quantity supplied up to point 2 and A1 and A2 the yields in points 1 and 2
  • A2 A1 (G1 / G2)
  • Fig. 10 shows similar to Figs. 3 and 9 in a yield / performance diagram the working points that arise if for the second, through a single filling and Lifting process from working point 1 reached working point 4 the condition specifies that the associated values of Yield A4 and power L4 of this operating point 4 one Point 4 on the straight line connecting the first Working point 1 and a working point AF on the Define the yield axis, which is a fixed maximum theoretical yield value for the material to be pressed corresponds.
