Description

one

The invention can be used in the industry of thermal insulation building materials for the manufacture of mineral wool products.

The purpose of the invention is to improve the quality of products based on shredded waste.

In Fig.1 schematically shows the proposed device, a General view; FIG. 2 is a section A-A in FIG. 1;

A device for the manufacture of mineral wool products contains a bunker in which a mechanism for grinding material is installed, in the form of shaft 2 rotating towards one another, made with grooves 3 and protrusions 4,. On the latter, radial needles 5 are placed for grinding material, and in slots 3 there are nozzles 6 for supplying the binder, mounted at an angle of 45-60 to the vertical (to the direction of movement of the material) and connected to the containers 7, the bunker 1 is connected with the box 8 to the material deposition chamber 9, which is made perforated, equipped with a suction nozzle 10, working from the fan 11, and a formacite working body in the form of a punch 12, designed with a perforated working surface in the shape of the product (in the form of a half-cylinder, external or internal surface of the half-pipe, or a flat surface),

Nozzle 6 with the help of the pipeline 13 is connected to the pipe 10 of the suction. Between the fan 11 and the chamber 9, a drip tray 14 is installed to collect excess binder and prevent contamination of the path of the spraying unit of the binder, made in the form of a perforated container filled with mineral water.

The placement of the nozzles 6 in the grooves 3 of the rotating shafts 2 ensures the application of the binder in the form of azrozole. by

.all surface of pieces of material. Placing the nozzles 6 at an angle of 45-60 to the direction of movement of the material. causes the torch spray to the entrance of the box 8,

Installing nozzles 6 at an angle of less than 45 or more than 60 does not provide the direction of the torch of the aerosol to the entrance of the box 8,

The device works as follows.

ZO

Mineral wool or carpet waste is loaded into a receiving hopper 11 with a grinding mechanism, mineralized waste, moving between shafts 2 rotating towards one another by means of radial spokes 5 are crushed into individual pieces, which immediately fall into the zone of nozzles 6 through which from the tanks 7 due to the pressure generated by the fan 12 ,. a binder is applied and applied as an aerosol on the material. The aerosol jets of the binder pick up the pieces and in the vortex flow, which promotes the uniform distribution of the binder. Over the entire surface of the material, they are transferred to a perforated chamber 9 where the material is deposited under the action of the vacuum created by the suction nozzle 10. When sucking the aerosol binder through a layer of precipitated material, additional binder is applied. After the perforated chamber 9 is filled with the required amount of material, the punch 12 is lowered, under the action of which, and due to the hot coolant flowing through it and the chamber 9, the product is molded

Part of pieces of binder material passing by (especially at the initial moment of the device operation)

enters the drier precipitant 14 and precipitates; given to the unmixed wastes contained in it, the non-precipitated part of the aerosol of the binder through the pipeline 13 enters the container 7 again with the reference signal.
