Description

(54) MIXING AND SHAPING SETTINGS

one

The invention relates to mixing-forming plants in the production of chipboard i and can be used in woodworking machinery / structures. ,

Mixing-forming installations are known, which include a dispenser with a discharge funnel, a mixer, a mixing chamber j with butterfly valves and nozzles, a conveyor, a re-circulator of flow with a roller, a suction pipe and a fan.

However, such installations do not provide | adjusting the flow of the crushed oil; in the process of mixing and uniform distribution of the circulating flow through the chamber width 15.

The purpose of the invention is to regulate the flow of chopped wood during the mixing process and to evenly distribute the recirculated flow over the width of the chamber.

This is achieved by the fact that the working correctness of the butterfly valves is made of a convex FSFM, and between the discharge pipe of the fan and the mixing box.

A lera is installed with a flow distributor, in the casing of which partitions are mounted, forming channels with uniformly varying cross sections.

FIG. 1 is a schematic representation of a mixing and forming installation, a general view of FIG. 2 - flow distributor with its frontal types;

The device has a funnel 1, a dispenser 2, a ripper 3, a mixing chamber 4, rotary nozzles 5, rotary valves 6, a conveyor 7, a calibrating roller -8, a suction pipe 9, a fan 1O, a distributor 11.

Mixing-forming unit operates as follows.

 Through the hopper 1 serves. the fiber into the dispenser 2, then to the ripper 3. The latter, breaking up individual lumps, yields the fiber into the chamber 4. Through the nozzles 5, the binder is fed into the fiber flow. By turning the flap 6, the uniform distribution of the fiber flow over the cross section of Chamber 4 is adjusted. The resinous grout falls onto the moving conveyor 7 and the chamber formed above the chamber 13 and the Calibration Smooths it smoothly & raising a carpet, lifting them into a suspended one; condition. The fiber in a suspended state - the Scientific Research Institute returns through a suction tube 6 and 9, the fan 10 to the current source 11 and then to the mixed first 4.,:, -g. I REFERENCE AND PLANT 1 Mixing-forming plant for the production of crushed stone boards, you and the binder, containing a dispenser with a discharge funnel, a grinder, a mixture- i 1: - -:}; an ash chamber with turning points and nozzles; the distribution of a sh-stream flow across the width Tsamery, the working surface of the dampers is made of a convex shape, and a flow distributor is installed between the discharge pipe of the fan and the mixing chamber, in which KopiQrce partitions are mounted s channels with uniformly varying section.
