Description

Fig 1

The invention relates to devices for the preparation of silicate concrete and silicate brick.

The purpose of the invention is to increase the productivity of the plant by allowing the preparation of the silicate mixture.

Fig. 1 shows an installation for transporting bulk materials, a general view; in fig. 2 - humidifier.

The plant for conveying bulk materials contains feeders 1 for metering the supply of silicate components to the material line, a tank 2 for the finished silicate mass, connected to the material pipe 3 feeders, a blower machine 4, connected to a capacity 2 for the finished silicate mass, a recycling material line 5, humidifier 6 in the form of a material-conduit element located between the feeders 1 and the container 2 for the finished silicate mass, the gate (gate) 7 on the recirculation material pipeline 5 at the blower 4 machines for the addition of air from the atmosphere, a valve 8 with a shutter in the upper part of the tank 2 to discharge part of the humid air into the atmosphere and a pump 9 for metered water supply to the humidifier 6.

The humidifier 6 is located between the feeders 1 and the tank 2 for the finished silicate mass and is made in the form of concentrically arranged outer with the pipe 10 and the inner perforated shells 11 and 12 and the end elements 13.

Installation for transporting bulk materials works as follows.

The components of the silicate mass (ash, additive, hydrated lime) dosing and at the same time supplied by means of feeders 1 to the material pipe 3, picked up by the air flow created by the blower machine 4, mixed with a turbulent air flow, moistened when passing through the humidifier b and enter s capacity 2 the form of the finished silicate mass. Coal ash and hydrate lime have high dispersion and relatively small bulk masses (600-800 kg / m, and the bulk mass values of ash and hydrated lime differ little, thereby ensuring good miscibility of the silicate mass components. Preparation of silicate mass occurs continuously during its transportation to the tank 2.

The ratio of the second component receipts in terms of the dry part in

pneumatic transport installation coincides with the ratio of components in the silicate mass. The optimum moisture content of the silicate mass at high humidity of its components is achieved by active ventilation of the mixture of wet components with a metered amount of fresh air from the atmosphere; at normal humidity of its components, the optimum

moisture content of the silicate mass is achieved by preserving the bound moisture in a humid air environment with a relative humidity of p 100%, with insufficient moisture content of its components, the optimum moisture content

silicate mass is achieved by irrigation of the air-material flow with a dosed amount of water.

If the components of the silicate mass are not sufficiently wet in the installation, then the gate 7 and the valve 9 are closed, and the humidifier 6 is pumped by the pump 9 to dosed water supply, and the initial moisture of the silicate mass is taken into account. water. If the moisture content of the silicate mass components is high, then the gate 7 and the valve 8 are opened, and the humidifier 6 is turned off. At the same time, in the process of pneumatic transport, the mixture of components is actively ventilated with fresh air from the atmosphere and the optimum moisture content of the silicate mass is achieved. Quantity of inflow

The air entering the atmosphere from the installation is controlled by a gate 7.
