Definitions

  • the invention relates to a housing shape for process engineering machines, especially miniature machines, which improves both manufacturing and assembly, as well as handling for the operator.
  • the invention is therefore an object of the invention to provide a solution that makes it possible to build the smallest machines that consist of as few components as possible, but have all functional surfaces, such as machines of large design and also easy to handle.
  • the object is achieved in that (characterizing part of the main claim), the housing parts have a polygonal basic shape and assume the different thickness of housing walls in cylindrical inner holes different functions.
  • the housing according to the invention of a process-engineering machine accommodates, for example, the drive of the machine, the working space with the rotating working part, as well as devices for the material task.
  • the housings are used in particular for dry and wet processing machines, including mills, classifier mills, cutting mills, classifiers, mixers as well as compactors.
  • the housings have at least one polygonal outer contour. Due to the polygonal shape, the housing parts which have a cylindrical inner bore have different wall thicknesses, these represent function carriers. Wall thickenings can be used to provide connections for purge air or cooling water supply. You can pick up machine components such as injector nozzles. Funnels for material feeding can be integrated into the housing part without the need for an additional component. Thereby, the number of components for such a mini machine can be minimized. Wall thinnings can serve as connecting surfaces to other machine components or plant components.
  • the fixing of housing parts and machine components takes place in that the components have fitting pieces which are pushed into one another.
  • the outer fitting is provided with threaded holes. These serve to receive grub screws with a conical end.
  • a conical recess is mounted opposite the threaded hole.
  • housing parts and connecting surfaces can be performed to other machines or other system components with a polygonal contour, they also have the advantage that they can be assembled against rotation and in a clear installation position.
  • polygon shape for the housings and connecting surfaces polygons with odd number of corners are preferred, especially the triangle.
  • the corners of the polygon can be rounded and the sides can also have a radius.
  • Profiles P3G according to DIN 32711 and P4C according to DIN 32712 are preferably used.
  • the polygonal outer contours of the housing parts are made by turning and grinding, the polygonal inner contours are preferably made by wire erosion.
  • the polygonal inner contour forms an interference fit with the polygonal outer contour, which forms a body after the shrink-fit connection that corresponds to monoblock production and is preferred for pharmaceutical applications.
  • the shape prevents the body after the composite, the initiation of a rotary motion, so the press-fit of the body must be secured against displacement.
  • the bodies have only one degree of freedom in the axial direction during joining. If this degree of freedom is determined by a device or measurement, it is possible to produce chambers or holes that are at an angle to each other by separate partial production of the blanks.
  • At least one housing part has a polygonal shape. If the housing parts to be joined together have a corresponding polygonal or polygonal inner contour, they can be joined together against rotation and joined together in an unambiguous installation position. In addition, the individual housing parts can already be equipped with holes and function carriers prior to assembly.
  • the polygonal shape has functional surfaces which make it possible to facilitate assembly and disassembly by means of rotational movement, since torque can only be introduced via the frictional force, as in the case of cylindrical components.
  • the blank (1) for a housing of a miniature machine is shown.
  • the blank (1) consists of a middle part (2) and a transverse part (3).
  • the outer contour of the two parts is a polygon, here a triangle with rounded corners and edges.
  • the inner contour of the central part also has the same polygon contour.
  • the blank (1) is formed by shrinking the middle part (2) with the transverse part (3).
  • the polygon outer contours (4, 5) are preferably made rotating and grinding. For this reason, on both sides of the central part (2) and cross member (3) projecting pins (6) with centering holes (7) and flat points (8) for receiving between tips and for rotary driving attached.
  • the polygon inner contour (9) is preferably produced by wire erosion.
  • FIG. 2 shows the finished housing (10), the from the blank (1) after FIG. 1 arises.
  • the sectional view of the work space (11) can be seen in the center.
  • Transverse to the working space (11) form rotationally symmetrical chambers (12) on both sides of the fitting pieces (13, 15) for receiving the drive and fines exit assembly with purge air supply chamber (14).
  • purge air supply chamber (14) For attachment of drive and fine material outlet tapped holes (16) are to be received on the cross member attached by pins in the area of thickening of the polygon contour.
  • For attachment and supply of rinsing and working air is a polygonal receiving pocket (17) with central mounting hole (18) and annularly arranged around the center holes (19) incorporated in the middle part (2) laterally at the flat of the polygon.
  • the straight through bore (20) hits the annular purge air supply chambers (14).
  • the starting from bore (21) perpendicular rising bore (22) establishes the connection to the driving nozzle receiving chamber (23).
  • the bore (24) establishes the connection for the passage of the working air to a mill or preparerunterteil. This eliminates out-of-machine lines or hoses.
  • the feed hopper (25) with supply line (26) to the working space (11) is integrated in the upper part of the blank (1).
  • To accommodate mill or withdrawerunterteil is a cylindrical Andrehung (27) in the lower part of the housing.
  • FIG. 3 shows the connecting element for fixing the machine components to each other.
  • the connecting element (28) is made of a screw with a conical end, which replaces the bulky clamp connections. Due to the special shape not only the components are firmly connected to each other, but also aligned with each other through the conical end of the setscrews. In most cases, a fastener is sufficient.
