Abstract

The invention relates to the field of production of precast concrete and reinforced concrete products, in particular, to the equipment of tunnel steaming chambers. In order to reduce the size, the steam trap separator is made up of bivalves in a vertical direction. Each flap is made of two paired shields, while guides on the upper flaps are fixed with guides for moving T-shaped ribs mounted on the shields of the lower flap. The upper flap is equipped with carriages for moving along guides in a crossbar attached to the ceiling of the chamber, and the lower flap is equipped with a carriage for moving along a vertical guide and with; it is connected with a pull rope with a lifting mechanism. 5 il.

Description

The invention relates to the production of precast concrete and reinforced concrete products, in particular, to the equipment of tunnel chambers for heat and moisture treatment.

The aim of the invention is to reduce the size.

FIG. 1 shows the separator of the steam chamber in the closed position; FIG. 2 and 3 are the same; intermediate positions in FIG. 4 are the same in the Open position; FIG. 5 is view A in FIG. 2

The separator of the steam chamber consists of the upper flap in the form of two paired shields 1 and the lower flap also in the form of two paired shields 2. On the upper shields 1 are fixed carriages 3 and guides 4, and on the lower shields 2 - T-shaped ribs 5, loops 6 and carriages 7, with the middle loop 6 of the lower flap locking the rope 8 of the lifting mechanism 9 mounted on the ceiling of the steam chamber 1 of the chamber 10. The guides are made in the form of racks 11 and crossbars 12 mounted into the walls of the steam chambers 10, and racks 11 are carriage 7, and in the bar nah 12 - the carriage 3,

The separator works as follows

in a way.

In the initial position of the separator (Fig. 1), the lower boards 2 are pushed up to the stop so that the entire separator hangs on the carriages 3 in the crossbars 12 and the cable 8 is weakened. The opening of the separator is carried out by the mechanism 9 of the subframe, after switching on which the cable 8 rises, is carried along by the lower shields 2,

with the T-shaped edge 5 along the guides 4, and the carriage 7 in the uprights 11 to the intermediate position (Fig. 2). After the lower shields 2 are moved to the upper ones up to the stop, the shields begin to rotate around the hinge loops 6 and the carriages 3 move along the crossbars 12 to the Open position (Fig. 4).

The proposed implementation of the separator allows to significantly improve the thermal insulation between the zones of the tunnel steaming chamber due to the presence of an air gap between the boards, to reduce heat loss and production area by reducing the dead zone at the place of operation of the separator.

F o rm u l a i: h o b r e s t s n i

The separator is steam cleaned (l 1 of the chamber, containing the upper and lower sashes, equipped with carriages, which are 1-fold with guides, and lifting mech.yyem, that and C and ii g so that the dimensions, the lower flap is also made in the form of paired shields, with the shields of the lower flap equipped with a T-shape with an edge,

the shields of the upper flap are guides with which the T-arm edge contacts, and the lifting mechanism is one chi with a single flap.
