SU390246A1 - INSTALLATION FOR THE APPLICATION OF THE CONCRETE MIXTURES BY THE PNEUMASON - Google Patents

Description

one

The invention of the invention of the construction of materials.

Replacement limes for pneumatic compaction of concrete mixtures containing a screw feeder with a hopper and a mixing chamber, a compressed air pipeline with a receiver, and a material hose with a nozzle.

The purpose of the invention is to provide the possibility of applying hot mixes to construction products.

This is achieved by the fact that heating elements are installed in the hopper of the screw feeder and the receiver, for example, in the form of tubular electrodes.

The drawing schematically shows the proposed installation, general view.

The device for a pevmonmonpryzg consists of a screw feeder 1 with a hopper 2, in which heating elements 3 are installed in the form of tubular electrodes. The screw feeder is connected to a screw working body 4 having an outlet into the mixing chamber 5, spun fins 6. The chamber 5 has an outlet to the material hose 7, ending with nozzle 8. The plenum 9 is connected to the chamber 5, which includes 10 He heating elements, Tami 11, also made in the form of tubular electrodes. To supply compressed air to the receiver, a line 12 is attached to it. For rotation of the screw feeder and screw auger, the unit is equipped with

drive 13.

The installation works as follows.

The hopper 2 is filled with concrete mixture and

elements 3 supply voltage. As a result

this concrete mixture is heated. Compressed

air from the compressor (not shown in the drawing) through line 12 enters the receiver 10, where it is heated by the elements //. The actuator 13 and the heated concrete mixture are turned on by means of the feeder 1 and the working body 4 are fed into chamber 5. At the same time, the receiver 10 pz via pipeline 9 into the chamber serves heated compressed air, which is mixed with the concrete 6 by a swirl 6. From the chamber 5, the aero-mixture through the hose 7 through the nozzle is released onto the surface of the workpiece 14. Due to the hot pneumatic spray, the condition of the hardening of the booster and the quality of the products is improved.

Subject invention

Pneumatic spraying machine

concrete mixes, containing a screw feeder with a hopper and a mixing chamber, a compressed air pipe with a receiver and a material hose with a nozzle, which, in order to ensure the possibility of applying hot mixtures, are installed in the hopper of the screw feeder and receiver. elements in the form of, for example, tubular electrodes.
