SU93001A1 - Heated Inert Material Hopper - Google Patents

Description

The known systems of inert material bins, heated with live steam supplied through perforated tubes and fitted with hermetic closures, do not provide for the determination of the moisture of inert materials and therefore make it impossible to precisely dispense water into the concrete. This leads to fluctuations in the water-cement ratio and a decrease in the strength of concrete.

The proposed booker does not have this disadvantage.

FIG. 1 shows a vertical section of the bunker along its axis; in fig. 2-bunker in horizontal section along L-A of FIG. one; in fig. 3- bunker, side view; in fig. 4 and 5 parts of the Niley-windows for the release of coidepsat and discharge channels in two projections.

The bunker / dl of inert materials (sand, gravel or P1, ebi) is settled in the mixing compartment and supplied with perforated tubes 2, but with which a sharp brew is passed.

The bunker has a dense vapor-proof overlap-. In order to receive material from a lifting conveyor 4 or another lift, the sluicing by means of an automatic shutter 5 with a counterweight 6, but not a single one inside the chute 7, was applied.

The material accumulating in the chute periodically deflects the bolt with its weight and is poured into the bunker, not a release of the vapor. For full w; two shutters are needed, but in this case there is no need to fight with small breakthroughs of steam from the bunker.

With the elimination of the boy, the reliability of operation of the lifting mechanisms, the durability of the bowel head increases, the working conditions of the personnel and the conditions of safety are improved.

Water passing through the holes of the material. getting from the ice and from the condensation of steam, falls on the conical walls of the bunker and flows down to the central hole.

To capture this water, slots 8 are provided, which are located along the conical part of the bunker themselves and are closed by overlays with filter nets 9 fixed on frame 10.

The ox is collected in the grooves //, which are inclined towards the collecting pipe 12. Periodically, the grooves and grids are poured from particles of clay and a thin layer. The approach of water to the nets is facilitated by some of the pressure created by the bunker in the bunker.

In the case of shelled windows, which may occur when the bunker is emptying, chute 1 can be closed with folding aprons from roofing iron to create a closed drainage section.

Subject invention

A hopper for inert materials with heating, equipped with perforated pipes for the inlet of a sharp bunker and hermetic closures, preloads them from the bunker, characterized in that in order to discharge excess condensate in order to obtain inertly moistened inert material from the bunker, - horizontal slit-windows are made, covered with nets and surrounded by gutters for collecting and draining water (condensate).
