(54) INSTALLATION FOR TREATING CONCRETE PLATES

(57) The invention relates to the processing of molded concrete products}

in particular to the device design

for machining molded reinforced concrete products, -6iiTb can be used for dimensional cutting of rejected reinforced aerated concrete slabs and figured processing of aerated concrete slabs and allows to increase the productivity and quality of cutting. When fluid is supplied from the cooling system 4 to the upper segment of the milling cutter 1 through the nozzles 5 fixed in the additional casing, the milling cutter 1 rotating by the drive 1 is intensely cooled. f-ly, 3 ill.

The invention relates to the processing of molded concrete products, in particular, to the construction of devices for the machining of molded reinforced concrete products, and can be used for dimensional cutting of rejected slabs of reinforced aerated concrete and figured processing of slabs of aerated concrete.

The circuit of the invention is the expansion of technological capabilities due to the possibility of cutting hygroscopic materials.

Figure 1 shows an installation for processing concrete slabs; figure 2 - section aa in figure 1; on fig.Z - section bb in fig.t.

The plant for processing concrete slabs consists of a milling cutter 1 with a drive 2 mounted on a movable frame, and a cytoclic casing 3, a system 4 ohlg-tdn with a coppant 5, located putrn tgtsitnogo casing 3 additional casing 6, covering the upper segment 7 of the milling cutter 1 The additional casing 6 is provided with plates 8 mounted obliquely, forming with the side surfaces of the milling cutter 1 a slit seal 9, and with the walls of the additional casing 6 - a collection of coolant 10, the cavity of which is interlocked with the drainage system 11. To improve reliability, the reservoir 8 us MO gut be provided by the milling cutter 1 straps 12, made for example of wood. The movement of the coolant from the moment it is supplied from the cooling system 4 to the surface of the milling cutter 1, to the collector 10 and to the drainage system 11 is indicated by arrows.

The installation for processing concrete slabs works as follows.

Segmcchp 7 milling cutter 1 through the nozzle 5, mounted in an additional casing 6, is intensively cooled by rotational drive 2 of the milling cutter 1. Coolant leaks onto the surface of the gas concrete slab are minimized due to a slit seal 9 formed obliquely mounted by plates 8. the gap in the mechanical seal 9, it is possible to use the linings 12 of soft material, for example, made of wood and their thickness selection. Cooling liquid, after cooling the cutter 1, ja, due to centrifugal forces of rotation of the cutter, hits the walls of the additional leather 6, and due to the inclination of the plates 8 merges through the collection 10 formed by the plates 8 and the walls of the additional casing 6 into the drainage system 11.
