Definitions

  • My present invention relates to a centrifugal. clarification or separation bowl in which the sediment and purified liquid are evacuated in continuousprocess.
  • Mypresent. invention has for its object. to, remedy this drawback and is. characterised essentially by the fact thatthe internal wall of the bowl is formed of angular faces which con.- verge. towards the. evacuation orifices. in the external wall of the bowl and by the fact. that the inside of the bowl is so designed that it exhibits no surface which through lack of inclination islikely to hold back the heavy particles during their displacement towards the periphery of the bowl.
  • the angular surfaces combine: with the shape of the bowl which consists of an upper and lowerv conefcontacting. at. their bases to form funnels which continuously drain off the separated sub-- stancesitowards. theevacuation orifices provided in the outer wall ofhthebowl.
  • The. evacuation orifices are formed by very shortgrooves arranged-tangentially in one Of'ther" two contact surfaces of the two halves. of'the: bowl or in both the said contact surfaces.
  • the twofhasli-bowls are centred one on the. other meansiof'a flange-provided on the only parts which donotform a-tight joint are' those corresponding to the evacuation orifices.
  • Fig. 1 shows, in. itsileftl'iand half a sectional view of the howl" and" in. its righthand half an elevation. showing; the. outsideot thev bowl.

  • a false bottom It provided on the back with a plurality of ribs or projections which converge towards the centre and form conduits l5 closed by two adjacent ribs, the base H of the bowl and the back of the false bottom Ml.
  • the liquid distributed between the plates is subjected to their separating action, the clarified part of the liquid being the lighteris evacuated through the conduits I5 and reaches the outlet orifices 56 formed in the lower part of the bowl and surrounding and guiding the delivery tube I.
  • a small portion of the light liquid is also evacuated through the conduits formed by the superimposing of recesses ll (Fig. 5) provided on the lower edge of the plates 6 and this portion is delivered to the orifices I6 through an aperture I8 in the false bottom 14.
  • the arrangement is such that the liquid charged with heavy particles finds no support during its evacuation against which the solid particles could accumulate until the bowl becomes completely choked.
  • the lower part or base ll of the bowl is of conical shape as is also the upper part 3 these two cones being joined at'their bases. In this way the heavy particles can reach the periphery of the bowl which is the line of contact between the two cones.
  • the lower part H of the bowl is so arranged that the spaces between the outlet orifices 29 are formed by angular portions 2
  • These grooves afford the advantage as compared with holes of small dimensions, of being easy to make and easy to clean.
  • the angular portions 2! are joined together at il in such a manner as to form an arris taking part in the centring of the stack plates.
  • the two halves of the bowl are centred one on the other by a flange 23 (Fig. 3) provided on the upper part of the bowl and engaging around the upper peripheral rim of the lower part II of the said bowl.
  • This fiange 23 is recessed (as shown at 24, Fig. 3) opposite to the outlet orifices formed by the recesses 29 which reduces to a minimum the length of the evacuation grooves and permits 4 of minimising the resistance to the flow of the evacuated sludge.
  • the two halves of the bowl are joined together by bolts 25 which pass through the angular portions 2!.
  • bolts 25 may be integral with the member H or the member 3 or they may consist of separate elements held in position by bolts 25 or again they may be cut on a horizontal plane such as for example at 29 and each of the parts would in that case be integral with the parts 3 and H.
  • the grooves 20 and 24 are completely unobstructed owing to the absence of a joint consisting of a ring of rubber or analogous material generally provided between the upper half and the lower half of the known bowls.
  • the only places which do not form a tight joint are those corresponding to the evacuation orifices.
  • the heavy substances accumulate in the casing 25 from which they are evacuated towards the outside at 21.
  • the angular portions 2i also determine the angle of downward how or slope of the heavy substances and it is possible to impart to the conical walls 3 or II an angle which is equal to or exceeds the said angle of flow. That is to say, the angular portions 2
  • the heavy particles separated from the liquid to be clarified can circulate freely in the bowl towards the evacuation orifices without encountering any obstacle.
  • outlets for the muddy liquid consist of very short grooves provided tangentially in one of the contact surfaces of the two halves of the bowl or in both the said faces.
  • the evacuation of the muddy liquid may be effected by means of jewels (rubies, diamonds, etc.) pierced centrally with an accurately gauged hole and which are arranged in orifices provided in the bowl at the apex of the delivery funnels for the muddy liquid.
  • jewels rubber, diamonds, etc.
  • jewels may be set directly in the bowl or can be previously set in a circular ring (jewelholder) which is inserted or screwed into the orifice drilled in the upper half or in the lower half of the bowl.
  • a circular ring jewelholder
  • means may be provided whereby it is possible to replace a jewel-holder set with a jewel of predetermined bore by another jewelholder in which is set a stone having a different central hole.
  • Fig. 6 In Fig. 6 is shown, as in the case of Fig. 1, the tube I through which the liquid to be treated is fed in, 2 the distribution chamber integral with the tube l, 3 the upper half of the bowl, 6 the conical plates forming a stack and H the lower half of the bowl.
  • the outlet of the muddy liquid is effected through jewels 28 (ruby, diamonds, etc.) pierced centrally with a hole 29 of accurately gauged dimensions (Fig. 7).
  • these jewels are set in a jewel-holder 30 having the shape of a circular ring, for example of brass, stainless steel; etc., which is inserted into an orifice 3i drilled in the lower half ll of the bowl opposite to the apex of the delivery funnels for the sludge.
  • This lower half is provided with a flange 32 engaged around the lower peripheral rim of the upper part 3 of the bowl.
  • the jewel-holder 30 is held in position by a grub screw 33 having notches 34 used for tightening the screw (Fi 7).
  • the jewel-holder may likewise be placed in an orifice provided in the upper part of the bowl opposite to the apex of the funnels delivering the sludge.
  • the bowl is fitted for example with jewels having a diameter of 0.3 mm. it is possible, in order to increase the quantity of muddy water to be expelled, to fit the same bowl with jewels having a central hole of 0.4, 0.5, 1 mm., 1.5 mm., etc.
  • the jewels may likewise be set directly in the bowl and in such case it is sufiicient to drill the evacuation orifices provided in the bowl to the exact diameter of the stone and to set the latter permanently therein.
  • This arrangement precludes the possibility of varying the quantity of muddy liquid to be expelled which may, however, differ with the nature of the liquids to be clarified.
  • the jewels retain in use a strictly constant diameter since any wear due to abrasion is practically impossible and the outlet of the evacuation orifices is thus maintained strictl constant.
  • Another modified embodiment of the bowl shown in the drawings consists in the fact that the assembling bolts 35 for the top 3 and of the bowl (Fig. 6) and the bottom half II are housed into these main parts whereas in the embodiment previously described these bolts emerge at the top of the bowl. This improvement permits of reducing the power absorbed by the bowl in motion.
  • a centrifugal separating bowl for continuous separation of liquids comprising a casing formed of upper and lower halves of conical shape and being joined along their meeting edges, a feed conduit disposed centrally within said bowl and having a flared extension forming a distribution chamber supported in the upper portion of said bowl, vanes vertically arranged and radially disposed in said distribution chamber to impart rotary motion to the liquid received therein, a pack of frusto-conical discs disposed in said bowl below said distribution chamber and around said feed conduit, said discs being spaced in superposed relationship to one another, ports arranged in said flared extension between said vanes, leading to said discs, each disc of the pack having openings formed therein which constitute substantially vertical conduits when said openings are vertically aligned, said conduits being in communication with said ports and with a discharge opening at the lower end of said bowl; jet discharge openings for heavy bodied material arranged in the periphery of the meeting edges of said casing, angular members having material depositing surfaces arranged within the casing around
  • a device in which the lower half of the casing. slopes uninterruptedly towards a discharge opening surrounding the feed conduit, the angular members being supported and secured on said sloping surface, the securing means comprising bolts.
