Wood Board Production Line

The utility model relates to the woodworking industry, in particular to the production of wood-based panels, and can be used to create lines for the production of wood-based panels.

A well-known line for the production of wood-fiber boards, including technological flows with sites for the manufacture of wood particles, sorting, drying, storage bins for dry wood particles, mixing wood particles with binders and additives, as well as a section for forming a wood carpet, pressing, format cutting of finished boards. (A.M. Kozachenko, B.D. Modlin, General technology for the production of wood-based panels, M., Higher School, 1984, p. 112).

There is also a known line for the production of chipboards, including technological flows with sites for the manufacture of wood particles, sorting, billets, storage bins for dry wood particles, mixing wood particles with binders and additives, as well as a section for forming a wood carpet, pressing, format cutting of finished boards. (A.M. Kozachenko, B.D. Modlin General technology for the production of wood-based panels, M., Higher School, 1984, p.21 - prototype).

A disadvantage of the known technical solutions is the lack of the ability to obtain wood boards from fiber

wood particles, which have indicators at the level of indicators of medium density fiberboard, but are produced at lower cost, according to simplified tennology and are now in great demand.

The technical task of the utility model is to expand the technological capabilities of the wood-based panel production line by producing wood-based panels containing fiber-like wood particles and having medium-density fiberboard properties.

The technical problem is achieved by the fact that in the line of production of wood-based panels, including at least two process streams with areas for the manufacture of wood particles, sorting, drying, storage bins for dry wood particles, mixing wood particles with a binder and additives, as well as a section for forming a wood carpet, pressing, format cutting of finished boards - the site for the manufacture of wood particles of one of the process streams is additionally equipped with devices for the manufacture of fiber-like wood clocks egg of petaloid chips and wood particles producing another portion of the process stream is further equipped with devices for the manufacture of fiber-wood particles from the pulp chips and / or needle-like chips. Devices for manufacturing fiber-like wood particles of both process streams are installed up to the drying sites. The line can be additionally equipped with a device for manufacturing fiber-like particles from substandard raw materials formed on both process streams, and can also be additionally equipped with a device for regrinding fiber-like wood particles. The line can be additionally equipped with a process stream for the manufacture of wood chips. The line can be additionally equipped with a process stream for supplying wood fiber into it used for the production of combined wood-based panels. The line can be additionally equipped with a process stream for preparing and / or feeding particles from non-wood material used for the production of combined wood-based panels into it. A wood particle manufacturing section comprising devices for manufacturing fibrous wood particles from wood chips and / or needle shavings may further comprise devices for processing lumpy wood processing waste products as well as plywood production. The utility model has the following differences from the prototype.

- a section for the manufacture of wood particles of one of the process streams is additionally equipped with devices for the manufacture of fiber-like wood particles from flake chips;

A wood particle manufacturing section comprising a device for manufacturing fiber-like wood particles from wood chips and / or needle shavings may further comprise devices for processing lumpy wood waste 62 and plywood production. Sleep FIG. not shown).

The line works as follows.

With crane 1 of process stream A, round timber is fed to disconnector 2, which piece by piece pass through the metal detector 3, get to the conveyor 4, from where they are loaded by the loader 5 into the chip machine 6 for making flake chips, which then goes into the raw chip hopper 8, and then into the device 9 for the manufacture of fiber-like wood particles. The obtained fibrous wood particles are conveyed by conveyor 10 to the drying section 11. The dried fibrous wood particles are sent through cyclone 12 to the sorting section 14, from which the bulk of the fibrous particles is obtained for the outer layer of the wood board and gets into

- 8 bunker storage bin for chip chips 15. A small portion of the obtained fibrous particles is larger, suitable for use in the middle layer of the wood board, is sent to the bin 37 for storage of dry fibrous wood particles. Substandard fibrous particles fall into the device 61 for regrinding, or, for example, to ensure they have a given shape or size.

With a crane 22 of the process stream B, round timber is fed to the uncoupling device 23, which piece by piece pass through the metal detector 24, enter the conveyor 25 and are loaded into the chipping machines 26 for the manufacture of wood chips (and / or chip machines for the manufacture of needle chips), and then the wood particles made (wood chips and / or needle wood chips) conveyor 27 fall into the sorting section 28. Technological chips made from lumpy waste feed to the same sorting section 28 woodworking with device 62 or from other sleep devices of FIG. not shown), processing all kinds of other waste products available at a particular enterprise. Substandard wood particles from sorting section 28 are discharged through vibratory chute 30 to dorazmol crusher 29 and returned to sorting section 28. Conditioned wood chips and / or needle shavings from sorting section 28 fall into raw chip bins 32, and then into devices 33 for making fiber-like wood particles. The obtained fibrous wood particles are sent to the drying section 34. The dried fibrous wood particles are sent through a cyclone 35 to the sorting section 36, from which the bulk of the fibrous particles is obtained

- 9 for the middle layer of the wood board and enters the storage bin for dry chips 37. A small part of the obtained fiber particles is smaller, suitable for use in the outer layer of the wood board, is sent to the bin 15 for storage of dry fiber particles. Substandard fibrous particles fall into the device 61 for regrinding, or, for example, to ensure they have a given shape or size.

From the hopper of dry fibrous particles 15, intended for the outer layers of the wood board, the conveyor 16 feeds the fibrous wood particles into the hopper feeder 17 and using the dispenser 18 are issued to the site 19 for mixing them with a binder and additives.

From the hopper of dry fibrous particles 37, intended for the inner layers of the wood board, conveyor 38, the fibrous wood particles are fed into the hopper feeder 39 and using the dispenser 40 are issued to the site 41 for mixing them with a binder and additives.

The ground wood particles are layered in layers in sections 44a, 446 and 44b of the carpet forming section and a wood carpet is obtained, which is cut in the device 46, and the waste from carpet trim is returned to the forming section. The formed carpets by means of a loading shelf 47 are loaded for pressing into a hot press 48, then by means of a loading shelf 49 they are removed from the press 48 and sent by a feeding mechanism 51 to a fan cooler 52 for conditioning, after which the boards are cut to size in section 53. Defective wood boards are processed in the crusher 50 and are directed to the drying sections 11

- 10 and 34. The formatted wood boards are polished in area 55, and the dust from grinding is collected in the hopper 58, then sent to the hopper 60, from where it is delivered to the hopper feeder 17 for use in the outer layers of the wood board. Harmful emissions from grinding are cleaned in the device 59. Finished wood boards are sorted and sent with a roller conveyor 57 to the finished goods warehouse.

The utility model will expand the technological capabilities of the production line of wood-based panels due to the production of wood-based panels containing fiber-like wood particles and having the properties of medium-density fiberboards.
