 Production method of wood granulae (pellets) / 2362798
Production method of wood granulae is based on use of furnace dead matter from low-grade wood as raw materials. The method involves pushing raw materials through an extrusion-type, perforated matrix in form of a plate with three-step shaped openings, in which there is division of raw materials into different parts, compaction and shaping of material in form of wood pellets. Whole timber is used as raw material, extruded under pressure of a hydraulic press. The openings of the plate are at peaks of regular triangles. Division of wood takes place at different hexagons using a system of parabolic teeth, the peaks of which at the corners of hexagons on the working surface of the matrix. The wood is compacted in conical channels with taper angle of 20°, shaping - by pushing wood through cylindrical openings.

The invention relates to a method and installation for the manufacture of briquettes from waste in the form of sawdust, husk, husk, etc. and can be applied at the enterprises of forestry, woodworking, grain processing industry and other enterprises with wood or plant waste for the production of briquettes to be used as secondary raw material or for combustion in domestic and industrial furnaces. The known method for producing briquettes from vegetable raw materials in the form of sunflower husks, sugar beet pulp, tobacco waste, etc. including supply, waste compaction, followed by molding and division (see the description of the author's certificate SU No. 925, IPC WV 11/20 from 15.12.1980 year). Briquettes are produced in a known manner, when the division have an irregular shape, which makes them difficult warehousing, in addition, they are not durable and spill during transport. The known method for producing briquettes, including supply, waste compaction, followed by molding and division (see description to the patent of Russian Federation №1047393, IPC 10L 5/44 from 24.01.1977 year). The known method is energy-intensive, as the raw material is then ground and dried before molding, and then subjected to drying the formed granules to a certain moisture content, which complicates and increases the cost of technology. Temperature mode pre the voting is not regulated, and is ensured by the pressure of the granulation, sufficient to provide the strength characteristics of the resulting granules in a known way equal to 3.2-12.7 mm, thus forming granules is realized by means of the mold, i.e. discretely. The technical objective of the proposed method is to reduce energy intensity and ensuring the strength characteristics of the briquettes. The technical problem is solved in that in the method for producing briquettes, including the supply of waste, their subsequent molding and division, while the briquettes are formed continuously and additionally thermoablative at a temperature of 150-350°C depending on the type of raw materials, shaping the briquette required cross-section, followed by division by measuring the required length. The method allows to produce briquettes from various plant materials, adjusting the temperature of the heat treatment and the pressing force. The proposed method is implemented as follows. First submit the raw materials in the form of plant waste humidity 4-12% and fractional composition of 2-10 mm, depending on the type of substrate, after which the raw material is pressed with the desired force depending on the type of substrate, then continuously formed into briquettes required cross-section and simultaneously thermoablative at a temperature of 150-350°C depending on the type of substrate, after which produce a de is giving into measured segments. Under the forces of compression and the temperature of the natural binder that is included in the composition of raw materials, plastification and binds the individual particles of raw material. Under high temperature, the surface of the briquette carbonitride, forming a protective shell. The composition and quantity of natural binders depends on the type of feedstock and its humidity and faction, so the mode briquetting selected for each type of raw material individually. The proposed method allows to obtain briquettes gauge length specified section, without the introduction of additional binder, it is quite thick and sturdy, which allows them to store and transport. The table shows the characteristics of the briquettes and raw materials for their manufacture.
A known device for producing briquettes from vegetable raw materials in the form of waste, namely sunflower husks, sugar beet pulp, tobacco waste and the like, comprising a housing with a hopper and drive pre is popping device (see description of the invention to author's certificate SU # 925675, IPC WV 11/20 from 15.12.1980 year). Constructive execution of the known device due to insufficient tonnage does not provide the briquettes of sufficient strength and does not allow the briquettes at the same size for the division, which makes their storage and transportation. The closest structural characteristics, taken as a prototype, is the setting for compaction bulk density, comprising a housing with a hopper and a tapered chamber, located suzhayuscyemsya end to the exhaust channel, and the driving of the pressing device in the form of a screw, which consists of two parts and secured along the conical chamber (see the description of the patent SU # 1692843, IPC 27N 3/28 from 23.05.1989 year). In the process of pressing in the known device is allocated a small amount of heat sufficient to melt the plastic coatings available on bulk paper pulp, and the formation of a form-retaining body used in the staging process chain. However, this heat is not sufficient to produce briquettes from vegetable raw materials in the form of waste, namely sunflower husks, sugar beet pulp, tobacco waste, etc. The technical objective of the proposed device is getting ravno is full of briquettes of the same shape and size, does not require individual packaging.
