Definitions

  • My invention relates to a machine for cleaning grains, bran and the like, including a beater rotor and a perforated drum.
  • Machines of the class set out are known in the art, in which the rotor and drum are conical and longitudinally displaceable relative to each other so that in operation the clearance between rotor and drum, and thus the effect of cleaning is adjustable. Owing to the unequal diameters, however, the wear and tear is nonuniform and so great that the maintenance of the machine is very expensive.
  • the machine of my present invention differs from such known machines in that it comprises a tangential inlet and means for adjusting the passage for the goods to be cleaned through the drum during operation of the machine.
  • ther advantage of such tangential inlet arrangement is that the high-speed beater rotor cannot suck any air through the inlet and thus also cannot produce any substantial degree of air compression inside the drum, with the result that a minimum of dust is introduced and deposited in the machine space surrounding the perforated drum.
  • the latter-as is well known produce a pronounced suction so that compressed air is blown through the perforated drum into the outside machine space, the walls of which thus soon are covered with dust.
  • Fig. 1 is a lon itudinal section of a cleaning machine on the line I-I of Fig. 2,
  • Fig. 2 is a cross-section on the line II-II of Fig. 1,
  • Fig. 3 shows a portion of Fig. 1 in a larger scale
  • Fig. 4 is a portion of Fig. 2 in a larger scale
  • Fig. 5 is a longitudinal section of a second example on the line VV of Fig. 6,
  • a fur- Fig. 6 is a cross-section on the line VI-VI of Fig. 5, and
  • Fig. 7 is a cross-section of a third example.
  • a perforated drum 2 is secured to the machine frame I, and 3 is the beater rotor rotatably mounted in the drum 2 and driven through the belt pulley 4.
  • the substantially tangential inlet comprises two sidewalls 5 disposed parallel to the axis of the drum 2, and two baffles 6 intermediate of the sidewalls 5 and pinned to shafts 2. The latter are coupled to each other through arms 8 and a link 9.
  • a U-shaped holder H] is secured to the latter and accommodates a cylindrical nut H2 in longitudinal slots II.
  • a regulating spindle I3 is screwed in the nut l2 and may be turned by means of a handwheel I4 (Figs. 3 and 4).
  • the two bafiles 6 may be adjusted simultaneously through turning the handwheel is so as to adjust the point of entry of the goods into the drum 2 longitudinally of the latter. It, therefore, is possible to change, i. e. lengthen or shorten the passageway of the goods from the inlet down to the outlet I5. It, thus, is possible to adjust the cleaning efiect during operation of the machine.
  • a fixed, tangentially arranged inlet I6 is provided in the perforated drum 2.
  • a plurality of baffles H are disposed over the entire length of drum 2 inside the latter.
  • the bafile are adjustable from the position shown by the full lines in Fig, 5, into the position shown by the dash-and-dot lines. According to the position of the baflles ll, the goods pass through the drum 2 on a shorter or longer way so that the cleaning effect may be correspondingly regulated.
  • FIGs. 5 and 6 as a modification an outlet 15 is shown, in which three closure slides 2!122 are arranged in line lengthwise of drum 2. According to which of the said three slides is open, the passageway of the goods through drum 2 will be different so that, also in this manner, the cleaning effect may be adjusted accordingly.
  • the drum is closed all around downstream of the inlet portion so that in the drum rear portion the goods rotate practically at the same speed as the beater rotor 3.
  • the beating action of the rotor and the cleaning effect in the said drum portion are substantially reduced therefore.
  • the drum 2 in the example shown in Fig. 7 is provided with a bay 23 which extends over its entire length and comprises an impingement face 24.
  • the goods are flung against the said face 24 through the rotor beaters. The latter subsequently again engage the goods falling back into drumZ in order to again accelerate .the goods and throw :the same up :against the face 24.
  • a machine for cleaning or scouring grain, bran or like materials having a beater rotor mounted on a horizontal axis, aperiorateddrum surrounding the beater rotor, means forming an inlet passage to admit material tangentially ,to the perforate drum, said inlet passage including two opposed vertical sidewalls and two bafiles mounted :for pivoting movement on horizontal of the material into said drum axially with respect to said rotor and to permit adjustment of the length of travel of material in said drum.
