Abstract

FIELD: mechanical removal of impurities. SUBSTANCE: device has bin 1 with loading man-hole coverable with cover 3. Hinged cover 4 with rotatable fixing members 5 is in the lower part of bin 1. There are slits 6 directed along the generatrix of bin 1 in cover 4. Splitters in the form of jalousie 7 are mounted above slits 6. Shaft of cultivator 8 connected with reversible motor 9 by means of belt transmission is located in bin 1. Bin 1 is connected with bin 11 for containing middle-size feather fraction by means of labyrinth 10. Bin 1 has two sections with hinged hatch 12 between them. The upper section has cultivator shaft with blades 13. Controlling sides of push-pull rod 14 and bin 15 containing down connected with exhaust hole 16 are upper part of labyrinths. The bins are connected with dispense chamber by means of down-and-air ducts. Exhaust hole 16 is connected with exhaust fan and is also connected with dispense chamber by another air duct. The air ducts have slides for controlling draught. EFFECT: enhanced effectiveness in separating feathers from down. 2 dwg

Description

 The invention relates to means for machining animal fibers.

 Known sorting device for down-filled raw materials, which consists of a loading machine with configured spare silo and is a two-, three-, or four-chamber machine with a suction pneumatic system and dust filter (Technological instructions for the processing of down-filled raw materials and the production of down-filled products in factories equipped with IBKA and LORH equipment, TI-49-1-2-80).

 The disadvantages of this device include a complex constructive solution that allows you to adjust the speed of the air flow in the maze of ducts connecting the bins of the sorting machine.

 Closest to the proposed technical essence is a device for separating feather fluff mixtures selected as a prototype, comprising a loading hopper with ripper blades, at least one raw material fraction storage chamber and an exhaust fan with a draft adjustment gate, dividers mounted on the rear wall of the hopper, a sensor noise and a control unit connected to it, the outputs of which are connected to the ripper drive and the gate control elements, in the lower part of the hopper along its generatrix link over which a gap crowns established a louver reversing drive configured ripper (av. binding. USSR N 1677099, cl. D 01 B 3/00, 1991).

 The disadvantage of this device is the lack of adjustment of the flow rate in the maze connecting the loading hopper and the filling hopper.

 The purpose of the invention is the improvement of the quality of sorting of downy feathers by regulating the air flow in the labyrinth sections of the ducts connecting the bins of the sorting machine while simplifying the design.

 Figure 1 presents a device for sorting down feathers; figure 2 the lower part of the hopper.

 A device for sorting down feathers contains a hopper 1 with a loading hatch 2 covered by a cover 3. At the bottom of the hopper 1 there is a hinged cover 4 with rotary latches 5, in addition, there are long slots 6 on the lid 4 located along the generatrix of the hopper 1. Above the slots 6 there are dividers in the form of blinds 7. In the hopper 1 there is a shaft of the cultivator 8, which is connected via a belt drive to a reversible electric motor 9. The hopper 1 is connected by a labyrinth 10 to the hopper 11 for the middle fractions of the pen, which consists of two sections hinged hatch 12 therebetween. The upper section contains a ripper shaft with blades 13. In the upper part of the labyrinths there are draft adjustment dampers 14, a down bunker 15 connected to the exhaust hole 16. The bunkers are connected by ducts 17-19 to the packing cabin 20. The exhaust hole 16 is connected by an air duct 21 to the exhaust fan 22, also connected to the tare booth 20 by the air duct 23. The air ducts 17, 18, 19, 21 and 23 have gates for adjusting the thrust, respectively 24-28.

 A device for sorting down feathers works as follows.

 In the initial position, the fan 22 is running, the shutters 27 and 28 are open, the shutters 24-26 are closed, the shafts of the cultivators 8 and 13 do not rotate.

 In the hopper 1 through the hatch 2 is loaded a portion of downy feathers. The lid 3 is closed, the electric motor 9 is turned on, which drives the shafts of the cultivators 8 and 13. The feather starts to rotate in the hopper 1, the heaviest fractions, which are the liner and impurities, are cut off by the blinds 7 and displayed outside in the hopper 1 through the slots 6. At the end the sorting process opens the gate 24 and a large feather is pulled out from the hopper 1 into the packing cabin 20. The selection of the fraction from the bins 11 and 15 is carried out as they are filled with material. The content of components in the fraction is regulated by the magnitude of the thrust in the channels of the labyrinth of the ducts using the shutters 14.
