Definitions

  • the invention relates to a vibration container for flocculating the waste water resulting from vibratory vibratory grinding or the like with an outlet pipe and an inlet nozzle, which continues into an inlet channel reaching into the interior of the container, which is assigned to the outlet pipe in a siphon-like manner and wherein the container has a connection nozzle for the Has addition of the flocculant.
  • Such an embodiment is known from DE-PS 2 243 092, the inlet channel being designed as a tube extending into the interior of the container.
  • the latter has the task of bringing the liquid flowing in from the inlet connection as close as possible into the bottom region of the container, specifically into the region of a connection connection there for the addition of the flocculant.
  • the area of application of such a container is limited in that complex processing fluids cannot be adequately treated.
  • the object of the invention is based on the object of specifying a generic container of simple construction which brings about an improved treatment of the wastewater, in particular during vibratory vibratory grinding, in such a way that preparation of the sewer network is possible even with chemically complex processing liquids.
  • This object is achieved in that the interior of the container is subdivided into several chambers arranged downstream of the inlet channel and in that the chambers downstream of the inlet channel have connecting pieces in the initial region of the throughflow, the first of which for introducing flocculation preparation chemicals and the last connecting piece for the addition of the flocculant.
  • the container works with a high output.
  • the chambers and the inlet channel are connected to one another, the surprising effect occurs that there is no backmixing or shifting back from one chamber to the other. Flow and vibrations are thus combined with one another in such a way that, on the one hand, they achieve good mixing and, on the other hand, exclude backmixing.
  • the vibration frequency is in the range from 13 to 34 Hz and the amplitude from 3 to 8 mm.
  • An advantageous variant is characterized in that the chambers are labyrinthine to one another and are formed by dividing walls which overlap in the vertical direction. Although the flow directions run opposite each other due to the labyrinthine chambers and the inlet channel, no backmixing or shifting back from one chamber to the other can take place.
  • the first connection piece is arranged in the initial region of the inlet channel and that of the adjoining chamber is located near the bottom of the container at the level of the transition cross-section to the first chamber which is left free by the first partition. This extends the treatment distance by the length of the inlet channel. Furthermore, the flow is promoted by the connection piece provided in the transition cross section.
  • the connecting piece for adding the flocculant is arranged in the upper region of the container, and the flocculation zone adjoining it extends over several chambers.
  • an emptying opening is provided in the bottom of the container in the region of the transition cross section of the two chambers connected one behind the other and a closable drainage connection is provided in the bottom region below the transition cross section released by the first partition.
  • Coarse grains or grit-shaped abrasive debris can be drained through the opened drain connection.
  • Another variant is characterized in that the individual chambers are arranged helically one behind the other. A chamber can extend over a spiral passage. In this version, too, undesirable backmixing of the liquid to be treated is ruled out.
  • the spiral chambers encompass the concentric inlet channel.
  • the space on the inside of the chambers is therefore used to accommodate the inlet channel.
  • an emptying opening is provided coaxially to the inlet channel below the starting area of the deepest chamber.
  • connection piece and the drainage piece lie radially directed to the outer container housing.
  • the container 1 according to the first embodiment shown in FIGS. 1-3 is firmly connected via an inlet connection 2 to the liquid outlet 3 of a helical vibration scrubbing container 4 of a conventional vibratory vibratory grinding machine.
  • the vibrating scrubbing container 4 could have any other known shape.
  • the processing liquid flowing in via a hose 5 and an annular shower 6 can therefore flow continuously into the container 1.
  • the container 1 participates in the vibrations of the vibration scrubbing container 4.
  • the container 1 is box-shaped. In the case of a vibrating scrubbing container 4 with a capacity of approximately 600 liters, its capacity is approximately 1 liter. Expressed in numbers, this means that the container has a width x of 55 mm and a length y of 120 mm with a height z of 150 mm.
  • the individual container side walls bear the reference numbers 7, 8, 9, 10, to which the container base 11 and the container lid 12 are assigned.
  • the inlet connector 2 extends from the container lid 12 near the narrow container side wall 7. In opposite position to the inlet connection 2 extends an outlet connection 14 connected to the tank bottom 11, which can be closed by means of a spring-loaded ball 15.
  • the interior of the container is divided into several chambers 1, II and III arranged downstream of the inlet channel 19 by three dividing walls 16, 17, 18 which overlap in the vertical direction and which are parallel to the container side walls 7 and 9.
  • the partition 16 starts directly on the container lid 12 so that the wastewater coming from the vibrating scrubbing tank flows through the passage cross section 20 of the container lid 12 into the inlet channel 19.
  • the partition wall 18 adjacent to the container side wall 9 also extends from the container lid 12, while the partition wall 17 lying between the partition walls 16 and 18 is attached to the container base 11.
  • the length of the approximately mutually parallel partition walls is shorter than the height z of the container, so that between the inlet channel 19 and the first chamber I a transition cross-section 21, between the first chamber I and the second chamber II a transition cross-section 22 and between the second chamber II and the third chamber III have a transition cross section 23.
  • the inlet channel 19 and the subsequent chambers I, 11 and III are arranged like a labyrinth to each other.
  • the inlet channel 19 has a connecting piece 24 fastened to the container side wall 7, through which a preparation chemical can flow.
  • a further connecting piece 25 is fastened to this container side wall 7 in the lower region, specifically at the level of the transition cross-section 21 to the first chamber I left by the first partition wall 16 downstream chamber I.
  • This connecting piece 25 is used to add a further flocculation preparation chemical, for example an electrolyte solution, which brings the pH value of the liquid coming from the inlet channel 19 into the range of 7.
  • the partition 16 extends approximately on the center line of the inlet connector 2 and the outlet connector 14.
  • the connecting piece 26 for adding the flocculant is arranged in the upper region of the container 1, namely this extends in the region between the two partition walls 17, 18 in the transition cross-section 22 between the first chamber I and the second chamber 11 Initial area of the flow on this connector 26.
  • the flocculation zone adjoining this connecting piece 26 accordingly extends over the chamber II and the chamber 111.
  • the container lid 12 is provided with a vent opening 30 above the flocking chamber II.
  • the wastewater coming from the inlet pipe 2 undergoes a treatment with the addition of suitable chemicals through the container 1 in the inlet channel 19, which takes part in the vibrations of the vibration scrubbing tank, and in the adjoining chambers I, II, III, so that the liquid leaving the outlet pipe 27 is prepared for the sewer network.
  • a multi-chamber process can be used. There is no risk of liquid shifting or mixing back from one chamber to the other. The flow is not adversely affected by the vibrations.
  • the container 31 according to the second embodiment illustrated in FIG. 4 has a cylindrical outer housing 32.
  • the bottom of the container is designated 33.
  • This continues into a collar 35 forming an emptying opening 34.
  • the emptying opening 34 is closed by a cap 36 which forms a locking rib 37 on the inside wall side. The latter engages in a locking groove 38 of the collar 35 on the jacket wall side.
  • a drainage nozzle 39 extends radially from the upper end of the container.
  • the interior of the container is subdivided into a plurality of chambers A, B and C which are arranged helically one behind the other, these spiral chambers encompassing the concentrically located inlet channel 40.
  • the aforementioned emptying opening 34 extends coaxially to this inlet channel 40 below the initial region of the deepest chamber A.
  • An inlet nozzle 41 opens into the upper end of the inlet channel 40 and can be firmly connected to the liquid outflow of the vibrating scrubbing container 4.
  • the chamber partition walls 42 are provided in a helically continuous manner on the outer circumferential surface of an insert 43 which is inserted into the outer housing 32 such that the chamber partition walls seal against the inner wall of the outer housing 32.
  • the firm fit of the insert 43 in the container housing is achieved by an upper clip edge 44 of the container housing 32 made of resilient material, which clip edge is supported on a shoulder shoulder 45 of the insert.
  • the insertion of the insert 43 is facilitated in that the clip edge forms an insertion bevel 46.
  • the chamber inner wall is equipped with a passage opening 47 there. From there, the liquid reaches the connection piece 48 provided in the initial region of the chamber A, through which a preparation chemical can flow.
  • the treatment liquid flows helically upwards to the connection piece 49 provided in the initial region of the second chamber B, through which the additional flocculation preparation chemical is added.
  • the flocculant substance is then supplied to the liquid, which rises in a spiral shape, in the initial region of the chamber C through the last connecting piece 50.
  • the preparation of the liquid to be treated which leaves the container 31 through the drain connection 39, takes place in this chamber C.
  • the connecting pieces 48, 49 and 50 extend diametrically opposite to the drain pipe 39 such that the distance between the individual connecting pieces corresponds to the slope of the helically arranged chambers one behind the other.
