Definitions

  • the housing wall at least in some areas, in particular over areas staggered in the axial direction of the drum, several with has approximately radial spacing between successive walls.
  • Separators of the type in question for the centrifugal separation of Solids from these suspensions containing are, among other things, often in used in the food industry, the chemical industry and the like. It is the rapidly rotating drum - which loads in a known manner and from which the solid and the liquid phase which has been clarified to that extent in the same way is dissipated in a known manner - in a housing, which is next to shielding the rotating drum against accidental access too Isolation tasks can perform.
  • a cooling zone can be provided for a temperature limitation in the area of the goods to be separated;
  • sound insulation due to the high rotational speeds generated noise between the drum and dampens the enclosure to the outside.
  • the interior of the housing by the air friction high-speed rotating drum disadvantageously become very hot.
  • a cooling jacket is provided, so you can with appropriate Effort taking into account the heat absorption from outside the Cool the housing relatively well, the coolant flowing through the cold room but does not have sufficient frequency insulation.
  • the invention is based on the charge, a housing of a separator in The type in question is more optimal with regard to its overall shielding effect shape.
  • the housing wall has at least three spaced walls, of which are formed therebetween Cavities, one a coolant and the other a sound insulation take up.
  • the housing wall is at least three spaced walls, of which are formed between them Cavities one receives a coolant and another an insulating agent.
  • the housing wall is at least three spaced walls, of which are formed between them Cavities one receives a coolant and another an insulating agent.
  • the simplest version is a three-walled chamber - radially outwards seen - provided the enclosure, which is thus two radially consecutive arranged chambers available, of which preferably the radial interior serves to hold the coolant, while the radially outer one Insulating agent includes.
  • the chamber that holds the coolant can also do more in particular or less divided channels divided in the axial direction of the drum his; those for the inclusion of sound and insofar also thermal insulation material
  • the provided chamber can be filled with insulating material, but it can the insulating material must also be placed in this chamber, especially in such a way that the insulating material, for example, from the outside to the radially inner limiting walls placed and then covered to the outside, namely with a cover to be added to the enclosure or also in such a way that the heat insulation layer radially outwards in this respect has self-supporting outer skin.
  • the coolant can in particular be a liquid flowing through the cavity be, in particular water or the like pumpable medium.
  • this Insulating agent also preferably based on solid-state heavy materials Bulk goods such as sand, glass beads, glass ball semolina or the like can be formed.
  • the housing is preferably made of at least two in the direction of the rotary axis Drum divided into successive areas, with two-part execution the lower area is cylindrical and the upper area is itself with respect to the cylinder diameter conical, preferably conical upwards is tapered.
  • the coolant is the leading one Cavities in both areas of the housing in the course of the composition connected to a successively merged unit.
  • the housing itself is a welded sheet metal construction or one Cast construction.
  • the radially outermost wall of the housing in the Connection or as the outermost cover of the insulating layer as a stainless steel sheet or specially coated sheet metal layer or as a correspondingly resistant Surface design of the insulating layer itself be formed.
  • the sound insulation is partly provided by the cooling medium, so that the soundproofing layer itself meets correspondingly lower requirements got to; This can be especially true when mastering a large Sound wave spectrum can be particularly important because of the attenuation certain frequency ranges from the cooling layer on the one hand and the actual one
  • the sound insulation layer has different effects can be designed.
  • the design of the housing according to the invention thus also enables several chambers and therefore walls not just a summation of the itself known effects of cooling on the one hand or sound insulation on the other, but opens up a wide range of possibilities in that the Design of the housing wall with both - if necessary multi-part - coolant chamber and parallel to it a chamber for receiving a (dry) soundproofing agent, either from home or targeted can also be designed to be heat-insulating, influencing each other and Support, but in any case allowed to achieve a combination effect.
  • the rotating drum 1 of the separator is driven at high speed with respect to their scope shown in dashed lines in the drawing.
  • a stationary housing generally designated 2 referred to, which surrounds the rotating drum in the radial direction of rotation seen with the axis of rotation of the drum 1 with a total of 3 Wall.
  • the housing according to the embodiment from a lower circular cylindrical section 4 and one following in the axial direction of the vertical axis of rotation of the drum arranged conical section 5.
  • the circular cylindrical lower section 4 comprises a housing 6 by the corresponding rectified hatching is recognizable and has a bottom part and an upper edge area, between which the circular cylindrical drum-shaped wall 3 is formed.
  • the upper conical region 5 also comprises a housing frame 7 with a upper annular area and a lower area 6 facing annular region 7, between which in turn the wall 3 is formed is.
  • the total designated 3 walls of both the circular cylindrical lower section 4 and the conical section 5 of the housing 2 each consist of three parallel walls, seen in the radial direction are successively spaced. Between the radially innermost wall 8 or, 8 'and the wall 9 or 9' adjacent in the radial direction is in each case one Cavity 11 or 11 'left open, which serves to hold a cooling liquid.
  • the cavities 11 and 11 ' can be continuous in the circumferential direction be formed, but they can also be subdivided and, for example, into Axial direction or conical run channel-like.
  • the insulation material is in Arranged circumferentially as far as possible and initially serves the Sound insulation, which is often and, in case of doubt, specifically heat-insulating is.
  • This insulating layer can, for example, by foaming the cavities 12 and 12 ', but prefabricated insulating parts can also be used, which placed on the wall 9 or 9 'and then outwards with a wall-shaped cover 10 and 10 'are provided. They can also Walls 10 and 10 'through an outer skin, for example compressed Insulator be formed.
  • Coolant - for example, circulation under the action of a pump - can for example in the upper region of the housing 7 of the upper conical Area 5 of the housing 2 can be initiated at 13 and occurs after flowing through of the cavity 11 in the transition between the conical region 5 to cylindrical region 6 of the housing 2 by one or more Transfer channels 15 in the cavity 11 ', depending on the design Conditions can have widenings 17 and at 14 from the lower Part of the housing 6 of the housing area 4 emerges. Like the drawing can be seen, even in the conical housing area 5 larger volumes Sections 16 are provided, which in a manner not shown with the Cavity 11 for receiving the cooling liquid in connection.
