Description

The proposed, according to the invention, method for the production of building parts from clay provides the following flowchart.

Raw materials (loams, loess, low-grade clays), extracted by a multi-bucket exavator or scraper and delivered to the factory, are delivered to the BOUNDARY SUPPLYER /, where 6-9% of fine coal with low-melting ash are simultaneously fed. The box feeder is used to evenly feed, meter and displace the raw material with fuel, as well as to break up large pieces.

From the SCHYCHNY SUPPLIER, the charge enters the scraper conveyor 2, which is fed into the drying chamber 3, where the drying of the pulpation takes place due to the heat of the exhaust gases from the heating conveyor passed through the drying chamber towards the mixture (countercurrent) and the radiation of the roof 4. The dried charge is conveyed by a scraper conveyor along chute 5 to a hammer mill-mill 6, where crushing and thin grinding is performed. The crushed mixture is supplied with a bucket elevator 7 to sepa / arop 5, from where it enters the heating conveyor belt 9, where

within 10-30 minutes - agglomeration and thermal softening of the mass occurs. To regulate the temperature on the conveyor, a zone-shaped blast 16 is used. Exhaust gases, passing through the drying chamber, are thrown into the pipe 17.

Thermally softened mass from the heating conveyor enters the universal rolling machine 10, where it is rolled; It is automatically cut into blocks of a given length and shape with a smooth or factored surface. Irokatny universal machine not only gives the rolled mass the proper shape, but also provides good density and uniformity. As a result, the blocks are of high quality.

From the rolling mill, hot blocks along the roller table enter the cooling conveyor 12, where they are automatically placed on the rib and evenly cooled. The cooling mode on the conveyor is set to within the allowable temperature difference across the thickness of the product, providing a cooling rate of 5-2 ° per minute.

The cooled blocks are removed from the conveyor by a grab gripper 13 and

687 No. 77036 by the electric hoist 14 along the monorail 15 is supplied to the finished product storage or directly to the motor transport. The subject of the invention. Method for the production of construction parts made of clay heated to sintering temperature, which is distinguished by mixing clay with fuel, for example, with coal, is crushed in a crusher “placed on a moving endless belt. in which the fuel contained in the clay is burned in order to heat the clay to the sintering temperature.
