The invention can be used in the production of heat and sound insulating building materials.

The purpose of the invention is to improve the quality of products.

FIG. 1 shows an apparatus for forming heat insulating blocks of fibrous materials, a general view; in fig. 2 shows section A-A in FIG. one.

The installation contains a mixer 1, a settling tank 2, a replaceable form 3 with a grate 4 fixed on its lower part and a finely meshed net 5, a drain tank 6 with a supply from the vacuum suction system 7, a pressing mechanism 8 and a sealed chamber 9 formed by walls 10 and 11.

On the walls 10 there are finely meshed meshes 12, representing the inlet of the vacuum channel formed by a sealed chamber 9, the volume of which is connected to the internal volume of the drainage tank 6. The height of the fine meshed mesh 12 corresponds to the highest height of the product molded on this unit . On the walls 10 are clamping straps 13 with gaskets 14, for example, from vacuum rubber. The strips 13 are bolted together with each other 15, the gaskets 14 are tightly pressed against the walls 10 so that the holes are (the fine mesh of the grid 12 is blocked to a height h corresponding to the height H of the molded article. Wall 10 is gesture 1310212

appropriate technological regulations.

The prepared liquid pulp is drained from mixer 1 through settling tank 2 into replaceable form 3, is displaced and partially filtered through finely meshed grids 5 and 12, and then the pressing mechanism 8 is activated and simultaneously vacuum suction is activated. 7. Dehydration of the forming pulp occurs both in the direction of pressing through the fine mesh 5 and in directions perpendicular to the direction of pressing and determined by the arrangement of the walls 10, -15 through fine mesh grids 12. At the end of the pressing and vacuuming processes the pressing of the pressing mechanism 8 rises, the vacuum suction is turned off, the interchangeable mold 3 with the molded block is removed and transferred to the subsequent process step. Further, the cycle of the installation is repeated.

The use of the installation, made according to the proposed technical solution, allows to obtain large-sized heat-insulating blocks from a liquid fine-fibrous and fine-dispersed mass with high isotropic properties that are equally dense in height. An improvement in equal density ratios improves the yield of products by at least 25%.

The walls are connected to the flange 16, on which, at 30% of the output from the well-known bolts 17, walls II are fixed to the bottom flange 18 of the drainage tank 6.

On the bottom flange 18 is also fixed valve device.

The installation works as follows.

Prior to the release of a batch of thermal insulating units with a height H, the strips 13 with the gaskets 14 are installed at the appropriate height h and tightened with the bolts 15.

The replaceable form 3 is clamped between the flanges of the settling tank 2 and the drainage tank 6. The components of the liquid pulp are loaded into the mixer tank 1 and the dispersion process is carried out
