Definitions

  • the invention relates to a device for separating coarse-grained solids from wastewater, in particular from slaughterhouses, with a auger rising in the direction of conveyance and with a tubular worm housing designed as a retention screen for the solids at least in a conveying section, which is connected to a wastewater inlet and an ejection opening for the solids
  • this waste water In order to be able to clean the waste water from slaughterhouses contaminated with meat, horn and hair parts, this waste water must first be freed from the solids, which causes difficulties because these solid parts quickly move the screening devices used for this purpose and then shut them down. In addition, this waste water is added not continuously but in batches and therefore oversized screening devices were required
  • the invention is therefore based on the object of designing a device for separating coarse-grained solids from waste water, in particular from slaughterhouses of the type described at the outset, in such a way that, with a comparatively simple structure, not only a high separation efficiency but also a high degree of maintenance freedom can be ensured
  • the invention achieves the stated object in that the Ford worm has a brush set against the tubular worm housing along the outer edge of its worm gear
  • the sieve punches are not moved even when the plastic solids are not dimensionally stable, because the sieve punches are constantly cleaned by the brushing of the worm gear
  • the requirement for the solid particles is supported by the brushing of the worm gear, because the brush bristles can connect to the housing wall without play. Otherwise, inevitable squeezing of the particles to be separated, which involves the laying of the sieve, between the worm gear and the worm housing is avoided, thereby not only ensuring safe transportation of the Solids retained in the housing relative to the waste water are reached, but also the risk of screen laying can be suppressed by the retained solids.
  • the device according to the invention ng is therefore particularly suitable for use in slaughterhouses and wherever due to the nature of the solids, rapid retention of the retention sieve by the solids must be feared, as is the case, for example, with the solids-laden wastewater from dairies and cheese factories or guest businesses
  • FIG. 1 shows a device according to the invention for separating coarse-grained solids from wastewater from a slaughterhouse in a schematic longitudinal section;
  • FIG. 2 shows a section of the Ford screw in longitudinal section on a larger scale and
  • FIG. 3 shows a cross section along the line III-III of FIG. 2
  • the device shown has a screw conveyor 2 mounted in a tubular screw housing 1, on the shaft 4 of which is mounted in end bearings 3 is driven by a motor 5.
  • the screw flight 6 of this screw conveyor 2 carries along its outer edge a brush set 7 on the inner wall of the screw housing 1
  • the screw housing 1 is made from a perforated plate and forms a retaining sieve 8 for coarse-grained solids, with hole diameters of up to 5 mm being possible, depending on the area of use
  • the snail housing 1 is enclosed by a collecting pipe 9 for the solid-free waste water emerging from the snail housing 1, whereby an annular gap 11 is defined between the collecting pipe 9 and the snail housing 1 by radial spacers 10 (FIG. 3) Snail housing 1 is penetrated.
  • This wastewater inlet 12 is provided at an axial distance from the lower end of the auger 2, so that between this wastewater inlet 12 and the lower end of the screw in the snail housing 1 there is a collecting volume for excess water from the batchwise water inflow Inclination of the waste water inlet 12 supports collecting the excess water prevents the separation effect from being impaired by waste water otherwise rising in the forward direction of the Ford screw 2 in the screw housing 1
  • the wastewater flowing out of the retaining screen 8 of the screw housing 1 through the collecting pipe 9 is fed to an intermediate store via a wastewater outlet 1 3 for further treatment.
  • the solids retained by the retaining screen 8 are discharged from the wet area of the outflowing wastewater by the conveyor screw 2 Via the screw housing 1, which is open at its top end, into the region of an ejection opening 14, which is formed by the upper end of the collecting tube 9, which is extended via the screw housing 1, as can be seen in FIG. 1. Via this ejection opening 14, they get out of the waste water separated solids in a collection container.
  • the brushing 7 of the worm gear 6 requires a cleaning effect on the retaining screen 8 which, for this reason, cannot move through the solids
  • both the collecting tube 9 and the screw housing 1 can be provided with an open cover 15 or 16, which is preferably connected to the housing or tube shell via an axial hinge joint

Abstract

L'invention concerne un dispositif permettant de séparer des solides à gros grains d'un effluent, en particulier d'un effluent d'abattoirs. Le dispositif proposé comprend une transporteuse à vis sans fin (2) qui monte dans le sens de transport et un carter (1) tubulaire de vis convoyeuse conçu, au moins dans une section de transport, comme un tamis de retenue (8) servant à retenir les solides et relié à une entrée d'effluent (12) et à une ouverture de décharge (14) par laquelle passent les solides. Afin d'obtenir un effet d'autonettoyage, il est proposé que la transporteuse à vis sans fin (2) soit pourvue, sur le bord extérieur de ses spires (6), d'une garniture formant une brosse (7) qui est en contact avec le carter tubulaire (1) de la vis convoyeuse.
