Definitions

  • the invention relates to a device for water drains of the kind described in the preamble of claim 1.
  • the first disadvantage is that the overf low openings are not re liabl e as the V-shaped s lots can easi ly become clogged during long periods with little precipitation so that they cannot not ful fi l their object, i.e. to rel ieve the fi l ter bag of water during e.g. a cloudburst.
  • the second disadvantage is that the mounting of the filter bag to the downwardly directed collar does not ensure tight contact between the upper edge of the bag and the collar, and during e.g. a cloudburst and with the sides of the openings adhering to each other an overpressure in the bag can easily cause the upper edge of the bag to be released from the suspension means on the collar so that the bag falls down.
  • a coarse-meshed wire basket which in this known device is placed on top of the downwardly directed collar to protect the filter bag against sticks and other pointed or sharp objects, cannot remedy said disadvantages.
  • the object of the invention is to provide a device of the kind mentioned by way of introduction which does not have the above-mentioned disadvantages. Said object is achieved by a device according to the invention having the features mentioned in the characterising part of claim 1.
  • a device according to the invention having the features mentioned in the characterising part of claim 1.
  • the overflow openings can be formed in the downwardly directed collar, but in order to make the collar as short as possible and to save the costs involved in making holes in it, the embodiment indicated in claim 2 is preferred, as only insignificant extra costs are in curred by making the holes in the fi l ter bags, e.g. by punching. In this manner, the size, shape, position and number of the holes can be changed merely by changing bags.
  • the invention also relates to a filter bag for use in a device according to the invention.
  • Said filter bag is of the kind mentioned in the preamble of claim 3, and according to the invention it is characterized by the arrangement indicated in the characterizing clause of claim 3.
  • Figure 1 in an isometric view illustrates a first embodiment of the filter means.
  • FIG. 1 in plan and side views, respectively, illustrates the filter means illustrated in Figure 1
  • FIGS 3 and 4 in the same way as Figures 1 and 2 illustrate a second embodiment of the filter means according to the invention.
  • the filter means 1 illustrated in Figures 1 and 2 includes two main components, i.e. a carrier plate 2 and a filter bag 3 mounted to the under-side of the carrier plate 2.
  • a carrier plate 2 which can be made of stainless steel, plastic or other suitable materials, an opening
  • the fi lter bag 3 is mounted to the carrier plate 2 by being placed on the collar 5 and fastened thereto by means of a strap 6, which can optionally be releasable with a view to an easy replacement of the filter bag 3.
  • a strap 6 which can optionally be releasable with a view to an easy replacement of the filter bag 3.
  • the filter bag 3 which can consist of a suitable water-permeable material such as nylon, a number of overflow holes 7 are made which connect the inside of the bag with its surroundings.
  • the carrier plate 2 is formed especially with a view to placement in a water drain, the upper side of which is covered by a grating (not shown) hinged to a frame (not shown) which is again mounted to or relative to the drain proper.
  • the carrier plate 2 is with a view to said use made with approximately the same outside dimensions as the grating, but in two adjacent corners it has cutouts 8 making room for the hinge flaps of the grating placed in said two corners.
  • Said hinged gratings are normally formed in such a way that in the completely open position they wil l hold the carrier plate 2 by clamping the part lying between the cutouts 3, and only persons who are aware of this fact will normally be able to remove the carrier plate, as for this purpose it is only necessary to swing the grating a short distance away from the completely open position so that the carrier plate is released.
  • the filter bag 3 can be provided with pockets (not shown) for placement of indicators made to detect pollutants in the water flowing through the drain.
  • Such pockets are preferably placed on the outer surface of the bag and preferably consist of a material which is transparent in such a manner that the indicators can be shown from the outside without being removed from the pockets.
  • the use of such indicators is especially useful in cases where the filter means 1 is placed in a drain, through which waste water from e.g. an industrial firm is flowing.
  • the filter means shown in Figures 3 and 4 is identical with the filter means shown in Figures 1 and 2 as regards all the parts having the same reference numbers as in Figures 1 and 2, and consequently, there is no need to describe these parts further, except for the carrier plate 2', which unlike the carrier plate 2 shown in Figures 1 and 2 is adjustable as it includes an adjustable side member 9, wherein transverse slots 10 are formed, and bolts 11 are led through the slots 10 and normal holes in the carrier plate 2' so that the side member 9 can be fastened to the carrier plate 2' in different positions corresponding to the size of the opening, in which the carrier plate 2 is to be placed. It is obviously within the scope of the invention to make the carrier plate unad just able of adjustable in other ways so that it can be adjusted as needed to the openings of the drains, in which the filter member is to be placed.

Abstract

Un organe de filtrage (1) destiné à être placé dans un drain (non représenté) se compose d'une plaque de support (2), sur la face inférieure de laquelle est fixé un sac de filtrage (3). Les gravillons, les cailloux, les branches et autres objets analogues qui ne doivent pas pénétrer dans le système de drainage sont retenus par le sac de filtrage (3), qu'on peut vider de temps en temps en retirant du drain la plaque de support (2) avec le sac de filtrage (3). Celui-ci peut être pourvu de trous de trop-plein (7) pour empêcher tout débordement, notamment après de grosses averses.
