SU201187A1 - INSTALLATION FOR CLEANING AND SEPARATION ON THE FRACTION OF TOBACCO PHARMACY - Google Patents

Description

Installations are known for cleaning and separating tobacco pharmacist fractions consisting of a bunker, a screw, fresh nitates, gratings for separating tobacco leaves, a conveyor belt, i.e., its extension area of a pneumatic caliper, filled with two exhaust chutes for heavy lirimes and petioles, cyclone to precipitate pharmacy and sieve separator to sort it out. The design of the proposed installation is simplified. It ensures the release of organic DUST in the form of a separate fraction. For this, a lattice for separating tobacco leaves is installed in a screw feeder, a sieve separator is connected to a pneumatic network, and the discharge section of the cyclone-precipitator is discharged barrel-shaped. The drawing shows schematically the proposed installation. The unit for cleaning and fractioning tobacco tobacco consists of a hopper (not shown), auger feeder /, a grid 2 for separating tobacco leaves installed in a screw feeder of a conveyor belt 3 having a pacojalial zone 4 of the pneumatic chamber 5 with two outlets chutes 6 and 7 FOR heavy impurities and petioles; cyclone 8 for sedimentation of pharmacy, the outlet section 9 of which is barrel-shaped, and sieve senator 10 for sorting the pharmacy connected to the pneumatic network 11. The pharmacy from the hopper enters the screw feeder. Here, with the help of the lattice 2, whole leaves or clilings are separated from it. Having fallen through the lattice, the pharmacy is poured onto the transport conveyor 3, which supplies it to the pneumatic chamber 5. In the latter, during the expansion of the pharmacy, the expansion zone 4 heavy impurities fall down and are removed through the chute 6. In the expansion zone of the chamber, the air velocity drops and the stem is coming from the air flow, they hit the damper 12, lose speed and move away through the chute 7. From the chamber 5, the pharmaceutical enters the cyclone 5, where it separates from the light organic HF, which is directed by air to the air a gadfly 13. The pharmamatura enters the exhaust section 9 of the cyclops and then into the GATE lock 14. The cycloi separates organic dust without pharmacist slippages into the duct 13. The pharmaceutical gates are supplied to the sieve separator 10 during the discharge valve. the flow of organic matter is additionally easily carried through the nozzle 15 and

The pneumatic network pipe 16. In the screening separator, the pharma unit is divided into separate fractions, after which it is removed from the installation.
