(54) INSTALLATION FOR RECEIVING SHORTY KENAFA FIBER

The invention relates to the field of primary processing of bast cultures and can be used to obtain short fiber kenaf from wet waste scutching.

A known installation for producing short kenaf fibers, comprising a feed conveyor installed in the course of the process for raising raw materials from the alloy channel, pressing a roll press, a ripper, a drying and cooking machine 11.

This installation is close to the invention in its technical essence and the achieved result.

The disadvantages of this installation are the lack of flow associated with the use of manual labor in feeding all the technological machines included in the installation, which leads to an increase in the unevenness in the thickness of the layer during the drying process due to triple transfer of material on drying rus.

This necessitates the introduction of an additional operation to form a uniform layer, performed manually.

The unevenness of the power supply of the plant with wet scraping waste, the high content of fires in them, the inability to establish the necessary clearance between the strong needles and the lower movable bed of the strong cooking part of the machine does not allow choosing the optimal treatment mode. The ineffectiveness of loosening waste wastes before drying makes it difficult for a hot agent to pass through the material and the high content of fires in the fiber waste leads to a considerable overconsumption of fuel.

The aim of the invention is to increase productivity and improve fiber quality.

This goal is achieved by the fact that the plant additionally has rippers installed in front of the squeezing machine and preparation machine during the process, with each ripper having an inclined axle conveyor, the outlet part of which (IX) is equipped with a fiber puller and combs placed above the conveyor belt.

The invention is illustrated in the drawing, which shows the technological scheme of the installation.

An installation for producing short fiber kenaf. Contains a raft channel 1, a feed conveyor 2 for lifting raw materials from channel 1, a ripper 3, consisting of an inclined conveyor 4 with spigots 5, leveling ridges b mounted above the conveyor, and a puller. 7 fibers. Under the conveyor there is a storage hopper 8, Behind the ripper 3 there is a feed conveyor 9 and a pressing roller process 10, a feed conveyor 11, another ripper 3, a feed conveyor 12, a drying machine 13, a feed conveyor 14, a third one: a littel 3 and preparator car 15.

The installation works as follows.

Wet fibrous wastes of bast scraping along the raft channel 1 are fed to the feed conveyor 2 and through it to the storage hopper 8 of the ripper .3. Upon receipt of a certain amount of wet scraping waste into the storage hopper 8 by the interaction of Kolkoplans 5, inclined conveyor, 4 and leveling ridges 6, the formation of the required layer and release of fires is achieved. The scraping waste enriched in this way is conveyed by the feed conveyor 9 to the squeezing roller press 10 and the conveyor 11 to the storage hopper of the next cultivator 3 for the enriched waste. When a certain amount of them accumulates, the material is processed on this ripper 3 and a uniform, continuous and loosening layer is created, which enters the drying machine 13 through the feeding conveyor 12. The dry waste of the bast which leaves the drying machine 13 enters the bunker storage hopper 8 through the feeding conveyor 14 subsequent delivery 3 for dried waste.

Here, a continuous, uniform and loosened layer is created to feed the cooking machine 15. A large part of the fires is removed.

The resulting finished short canaf fiber is sorted, pressed and shipped to its destination.

The plant processes wet bast scraping waste from the flotation and washing machines through the raft channel.

Creation of mechanized feeding of technological machines and improvement of technological pro. The process eliminates manual labor, allows you to organize the work of a production line for the production of short fibers

in conjunction with two long-fiber production lines and increases equipment productivity.

Removing the bulk of the fires from scraping waste before the drying and cooking machines makes it possible to significantly reduce the moisture content of the material before drying, reduce fuel consumption and mechanical impact on the material after drying. The loosening of the scraping waste is of great importance for the efficiency and stabilization of the drying process due to the passage of the hot agent through the entire mass of material.

5 Improving the quality of waste treatment in the production line allows to increase the proportion of high short fiber numbers.
