Abstract

Use in the construction industry pni Summary of the invention the concrete mixture, for example, is compressed by means of the np xc.yiouiero auger mechanism 3, the liof MI is isolated, its water-cement emulsion is removed from the bottom-1 emulsion emulsion by separator B and under pressure , with a liquefied hour of 1 L, in the concrete mix, fill the concrete with a mixture of Form 2 and a Mo. until hardened for 2s and F-1

Description

The invention relates to methods and devices for the manufacture of building products from concrete and mochet to be used in enterprises of the construction industry

The purpose of the invention is to improve product quality by eliminating air inclusion from the mixture.

The indicated goal is achieved by that. that the concrete mixture is separated from the air inclusion and returned under pressure to the concrete device bottom seal

To this end, the installation is equipped with a discharge pump and a separator, the cavity of the screw housing is communicated on the mold side with the outlet of the injection pump, and the vacuum output and the entrance of the bending pumps are communicated with each other through the separator, and the screw in the section from the hopper to the separator has a conical section

The drawing shows an installation for the manufacture of concrete products.

The installation comprises a hopper 1, the supply of concrete mixture from

4, connecting the hopper with the Ub CK shape, has a middle conical section, including a focal concrete CMI gy i and the extreme cylindrical parts A and L, which can only be transported by SMS

The auger is driven by an electric gel L. In addition, the installation contains a vacuum 6 and pump 7 pumps and the output of which, respectively, are connected to each other through a separator 8, and the input and output of which, respectively, is consistent with the form of the mold connected through holes in the housing with the internal cavity of the oneke housing .

Vcipoficren works as follows

Concrete mixture is fed into the hopper 1, which is captured by the cylindrical part A of the screw 3, driven by the electric motor 5 and move i inside the coagus 4 of the screw 3, and the direction) Form 2 In the non-conical part of the screw 3, the concrete mixture is compressed to 2 kg / cm and produce e from oi i a single-cement emulsion with the help of a pump 6 into a separator L GDR

the water-cement emulsion is released from air inclusions. Os. The water-cement emulsion beaten from the air is pumped by pump 7 at a pressure of 1.2 kgf / cm into the cavity of the enclosure C. Part of the emulsion saturates the concrete mixture, and part of the emulsion passes through the mixture through the pressure difference towards the connection of the vacuum pump 6, additionally elimination of air from the concrete mixture in the interval between the cavity of the screw housing between the masos, repeat the cycle through the separator 8. The compacted concrete mixture enters the mold 2 and is distributed in the form, which helps, for example, to establish ka forms but the shaking table.

Claims (2)

SUMMARY OF THE INVENTION 1. A method of manufacturing concrete products, comprising filling a compacted mixture of a mold with preliminary evacuation and subsequent exposure to hardening, characterized in that that, in order to improve the quality of products by eliminating air inclusions from the mixture, the concrete mixture is separated from the air inclusions and crushed back into the concrete device for compaction. 2. Installation for the manufacture of concrete products containing a hopper and a mold connected by a device compaction of the concrete mixture, made in the form of a screw installed in a sealed enclosure, the cavity of which is connected from the side of the hopper with the inlet of the vacuum pump, with the exception of that. that, in order to improve the quality of products by eliminating air impurities from the mixture, the installation is equipped with a discharge pump and a separator, while the cavity of the screw housing is communicated from the mold side with the outlet of the discharge pump, and the exit of the vacuum and the entrance of the discharge pumps are communicated with each other through the separator, the screw in the section from the hopper to the separator has a conical section. 5 0 wLjf:
