Abstract

The invention relates to a technique for the separation of bulk materials and can be used in the grain processing industry. The purpose of the invention is to improve the quality of the separation of grain and to ensure the possibility of its even release into the subsequent processing cycle. On the cover 2 of the receiving hopper (PB) 1 there is a receiving nozzle (PP) 3. On the vertical shaft 5 in PB 1 there is a distribution sieve (P) 4 in the form of a truncated cone, facing a large base to the FPS. The smaller base P 4 is connected to the vertical shaft 5. On the peripheral part of the large base P 4, the blades 6 are radially fixed in the chamber 7. A cylindrical chamber 7 with an outlet is placed between the FPS and PB 1. Here, P 4 is mounted for rotation and vertical oscillations. An eccentric 15 is fixed on the shaft 5 in its lower part, which is connected to the exhaust valve 17 by means of a clamp 16. The grain enters the P 4 through the CRP, where it is evenly distributed and intensively sieved through the rotational movement and vertical oscillations. Unwrought particles under the action of rotational motion and oscillations move along the inner surface of p 4 to its greater base, where blades 6 are picked up and output. The eccentric 15, through the tug 16, communicates oscillations to the exhaust valve 17, whereby the grain from the receiving hopper uniformly flows to the separator. 2 Il. About SP S 00 WITH

Description

The invention relates to the separation of bulk materials, in particular to receiving and distributing devices for grain separators, and can be applied in the grain processing industry.

The purpose of the invention is to improve the quality of the separation of grain and to ensure the possibility of its even release into the subsequent processing cycle.

FIG. 1 shows a general scheme of a receiving and distributing device} in FIG. 2 is a section A-A in FIG.

The receiving-distribution device of the separator contains a receiving hopper 1. On the lid 2 of the receiving hopper 1, a receiving nozzle 3 is installed, which communicates with the receiving hopper 1. In the receiving hopper 1, a distribution grid 4, made in the form of a truncated cone connected by a smaller base with the vertical shaft 5, is displaced. In this case, the larger base of the conical sieve 4 faces the receiving pipe 3 and the blades 6 are radially fixed on its peripheral part. A cylindrical section is placed between the receiving pipe 3 and the receiving bin 1 chamber 7, provided with an outlet pipe 8, located tangentially to the lateral surface of the cylindrical chamber 7. The blades 6 are placed in the cylindrical chamber 7.

The conical sieve 4 is equipped with a vertical oscillation vibrator, made in the form of an electric motor 9 with unbalanced weights 10. The conical sieve 4 is connected to a vertical shaft 5, for example, a spline connection, which allows vertical movement of the conical sieve 4 along the vertical shaft 5. On the vertical shaft .5 a cylindrical spring 11 connected to a conic sieve 4. This spring protects the vertical shaft from the vertical vibrations of the conical sieve 4. The vertical shaft 5 is connected to an elec The actuator 12 through the belt transmission 13. The receiving hopper 1 is equipped with a rubber seal 14 at the outlet of the vertical shaft 5. On the vertical shaft 5 in its lower part an eccentric 15 is fixed, which is connected to the exhaust valve 17 located in the lower part of the receiving bunker 1 .

Receiver-distribution device of the separator works as follows.

The actuator 12 by means of a belt drive 1 3 rotates a vertical shaft 5. Vertical shaft 5 transmits rotation to a conical sieve 4 fixed on it, which besides performs vertical oscillations, communicated to it by a vertical oscillator. The grain through the receiving pipe 3 enters the conic sieve 4, where under the action of the rotational movement and vertical oscillations of this sieve it is evenly distributed and intensively sifted through it. Neither particles (extraneous impurities) under the action of 1 rotational motion and ver

The tick oscillations are moved along the inner surface of the conical sieve 4 to its larger base, where the blades 6 are picked up, transported through the cylindrical chamber 7 to the outlet nozzle 8 and removed from the receiving and distributing device. The movement of particles on the inner surface of the conic sieve 4 is provided by the centrifugal force arising from the rotation of the conical sieve 4 and pressing the particle to its surface and by throwing these particles as a result of the vertical oscillations of the sieve 4. The grain passed through the conical sieve 4 distributor, they are uniform in size and, due to the rotation of the conic sieve 4, are uniformly distributed in the receiving hopper 1. The eccentric 15 mounted on the rotating vertical shaft 5 through the pull 16 oobschaet oscillation outlet valve 17. Due to variations in outlet valve 17 the grain from the hopper 1 is uniformly supplied to the working of the separator body.
