Definitions

  • the invention relates to a multi-deck sieve machine designed as a throwing sieve with sieve, blind and return decks clamped in the frame and a vibration exciter arranged on the sieve stack for classifying dry, free-flowing bulk goods of small grain size, such as abrasives and blasting media, with which a large number of grain size classes are carried out in one operation can be classified.
  • Multi-deck screening machines designed as throwing screens are already known.
  • Such a known multi-deck screening machine consists of several screen decks arranged one above the other on a base frame, which are inclined by 30 ° to 40 ° to the horizontal. Vibrating heads are arranged on the sieve housing.
  • Multi-deck screening machines designed as throwing screens with return of the screened material against its transport direction, with which a large number of particle sizes can be classified in one continuous continuous operation, are not known.
  • a multi-deck screening machine operating as a flat screen which consists of screen, blind and return decks which are clamped in a frame and in which the screen stack thus formed is excited as a whole.
  • the inclination of the sieve stack can be adjusted depending on the required dwell time of the material to be sieved on the sieve bottom and its flowability.
  • the drive takes place by means of an eccentric acting in the horizontal direction (company lettering "Regula-Siebmaschinen" from J. Engelsmann AG, 67 Ludwigshafen / Rh. FRG).
  • This multi-deck screening machine allows the material to be returned, it is also possible to classify up to six grain size classes in one operation using such multi-deck screening machines.
  • Plane screening machines generally have the disadvantage that the screen floor is only moved in the screen plane and thus only the gravity, which causes the movement through the screen floor, acts on the undersize.
  • the reason for the necessary parallel and series operation when solving screening tasks that require the bulk material to be classified into a large number of grain size classes is that the known multi-deck screening machines designed as throwing screens do not allow the screenings to be returned and the multi-deck screening machines designed as plane screens in the Fine grain area does not work with sufficient selectivity, so that with such multi-deck screening machines only up to a maximum of six grain size classes can be classified in one operation. It is therefore the object of the invention to develop, for the first time, a multi-deck sieve machine designed as a throwing sieve, in which it is possible to return the material to be screened against the direction of transport and which works with a high degree of selectivity in all grain size classes.
  • this object is achieved in that a vibration exciter known per se is arranged so displaceably and rotatably on a sieve stack that its line of action acts at an angle of 45 ° ... 85 ° to a horizontal on the sieve stack and vertically free-swinging in a return deck and inclined at 0 ° ... 30 ° to the horizontal and articulated to a frame of the return deck. It is also characteristic that the channels end at the ends in vertical channels in the sieve stack and several channels are coupled to one another at their ends.
  • the multi-deck screening machine consists of a screen stack, a vibration exciter and the grain removal.
  • blind and return decks are firmly clamped using a clamping frame and a clamping device.
  • a vibration exciter is slidably and rotatably fastened so that a throw angle and the line of action of the vibration exciter can be adjusted from 45 ° to 85 ° to a horizontal.
  • channels are suspended from springs in a vertically swinging manner. They have an inclination of 0 ° ... 30 ° to the horizontal and are articulated at the ends to the frame of the return deck. Several channels can be coupled together at the ends.
  • the sieve stack is excited as a whole by the vibration exciter.
  • the multi-deck screening machine according to the invention is preferably suitable for solving screening tasks in which the bulk material can be classified into a large number of grain size classes in one operation. It is particularly suitable for classifying abrasives and abrasives, but is not restricted to this area of application. With the solution according to the invention, it was possible for the first time to secure the return of the material to be screened against the throwing and transport direction of the material to be screened on the screen and blind decks in the case of a multi-deck screening machine designed as a screening screen.
  • FIG. 1 a side view of the multi-deck screening machine
  • FIG. 2 a section through the return deck
  • Figure 3 a top view of the return deck.
  • the multi-deck sieving machine consists of the sieve stack 1, which is arranged on the oscillating frame 2.
  • the sieve and blind decks 3 and the return decks 4 are arranged one above the other in the sieve stack 1.
  • the screen and blind decks 3 and the return decks 4 are clamped together by the base frame 5, side frame 6, cover frame 7 and the tensioning device 8.
  • the sieve stack 1 seated on the oscillating frame 2 is supported on springs 9.
  • the vibration exciter 10 is slidably and rotatably arranged. This makes it possible, 11 1 to adjust the line of action of the excitation force of the vibration generator 10 to the stack of sieves as to form a roll angle of 45 0 ⁇ 85 ° with the horizontal.
  • the screened-out grits are discharged via the grit discharges 12.
  • several channels 13 are provided in the return deck 4, which are inclined 5 ° from the horizontal against the tranapor direction A of the material to be screened. These channels are suspended on the springs 14 in a vertically free-swinging manner and are connected at their ends to the frame 15 of the return deck 4 in an articulated manner 16. A plurality of channels 13 can be coupled to one another at their ends 17 in order to bring together material flows.
  • the screen stack 1 rigidly arranged on the oscillating frame 2 is excited as a whole by the vibration exciter 10.
  • the vibrations can act on the sieve stack 1 in accordance with the sieving task to be solved.
  • the return of the material to be screened against the transport direction A of the same to the screen base is ensured by the vertical oscillating movements of the channels 13, which are caused by the excitation of the screen stack 1.
