SU36416A1 - Continuously operating extraction apparatus - Google Patents

Description

The preparation of turpentine and rosin by extraction with organic solvents from resinous wood usually takes place in perirdically working individual extractors or the same extractors combined in a battery. The use of continuous extraction apparatuses in the canniple-turpentine production meets a number of difficulties which mainly boil down to the fact that, until now, all the continuously operating extractors that have been proposed are equipped with complicated mechanisms for moving the extractable material in the apparatus and have relatively little throughput of raw materials and therefore suitable for the processing of such bulky substances which is resinous wood shredded in the wood. I offer a continuous-action The extrusion device, fully utilizing the principle of countercurrent, is equipped with a mechanical device for loading and unloading the device; The use of extractable material, inside the apparatus, is beneficial — the gift of the emergence of chips in a liquid — with a larger specific gravity, —than uieijia because of the specificity of the specific gravity. ;

 : C59); -. . - -. The drawing shows an axial section of the proposed dry-acting extractor designed for extracting rosin and turpentine from resinous wood crushed into chips, having a specific weight, which is less than chips, which consists of a cylindrical vertical vessel 12 with a conical bottom, 0 Concentricly inserted 13 on the fasteners 17, which by its lower end does not reach the bottom of the vessel, the pipe axis on the subcaps 2 and 7 reinforces the full shaft 3, driven by the drive 1; teeth 5 are fastened on the shaft, with the aim of loosening the chips lying in the bun, "4. Chips entering the extractor -Disable with a disk feeder 6, planted on the same shaft 3. Fastened by a screw thread with a screw 8 has to immerse a continuously incoming drill chips, the fluid that filled the entire extractor, and push the chips to the book open KQHuy pipe 13, from which the chips are pressed and, due to the smaller; specific weight than solvent, probes .- azeta. The entry into the annular space by the walls of the vessel 12 and the tube 13, |:,

extracted mass of chips. During the movement of the shaft 3, the scrapers 9 CHHMaiQT, the upper layer of the extracted grain and push it through the fitting 15. Into the apparatus for regeneration of the solvent absorbed into the chips.

The solvent continuously enters the apparatus through the perforated ring through mfyueo 10, rinsing the weight of the chips towards it, enters the tube 13 from below, encounters the chip pulled down the tube down by the screw 8, and as a solution rosin and turpentine flows out through the holes 11 of the tube 14 strengthened in the fitting 18 along the axis of the pipe 13, The upper end of the pipe 14 freely enters the full shaft of the screw 8.

The body of the extractor is equipped with consoles 16 for fastening the apparatus 16, inspection and unloading hatches and fitting 18 for periodic descent of heavy particles.
