SU1664766A1 - Apparatus for manufacturing of double layer brick out of powder mass - Google Patents

Abstract

The invention relates to the technology of manufacturing two-layer products from loose masses on presses of semi-dry pressing and can be used in the manufacture of bricks from clay and silicate mixtures, as well as from production wastes. The aim of the invention is to increase productivity by combining in one stage the process of forming a two-layer semi-dry brick with a protective and decorative layer on a spoon surface. A device for producing a two-layer brick of powder mass makes it possible to produce a brick with a protective-decorative front, a spoon surface with a single firing and includes two bunkers 1, 2 installed one inside the other, from compartments 3 of which are two different powders through a tubular chute in the pipe, they enter the window of the loading carriage 5, which is divided by plates into pockets for the front and base powder, and the raw brick is formed with a protective and decorative spoon layer into the molds. 4 il.

Description

The invention relates to the technology of manufacturing two-layer products from loose masses on presses of semi-dry pressing and can be used in the manufacture of bricks from clay and silicate mixtures, as well as from production wastes.

The aim of the invention is to increase productivity by combining, in one stage, the process of forming a two-layer semi-dry brick with a protective and decorative layer on a spoon surface.

Figure 1 shows the device bins; figure 2 is the same, top view; on fig.Z. - carriage device; 4 shows the principle of forming a two-layer brick (section A-A, BB, C-B).

The hopper 1 for the face powder is fixed in the hopper 2 for the base powder. The hopper 1 is divided into compartments 3, the lower plane of which is above the pockets 4 formed in the loading window of the carriage 5 by the plates 6. The card 5 moves along the matrix 7.

In the matrix 7 are the mold 8 with the lower punches 9, and above the die are the upper punches 10.

A device for producing a two-layer brick of powder mass works as follows.

The face press powder (a mixture of low-melting clay, refractory clay and pigments) is fed into the hopper 1. The main press powder is loaded into the hopper 1 (light-melt coarse clay). From the compartments 3, the facial powder enters the pockets

4, and the main powder fills the remaining space between the plates 6 and the walls of the carriage 5 (FIG. 4a). The carriage makes a reciprocating motion (Fig.46). The lower punch 9 is lowered and down. the press powders from the carriage 5 fill the mold 8.

The locking part of the carriage 5 blocks the supply of press powders from bins. The carriage 5 is moved to the right (Figure 4b). The upper punches 10 are lowered and pressed raw brick 11 into the mold 8.

Next, the upper punch 10 rises, the lower punch 8 pushes the brick out of the mold 8, the carriage 5 with press powders in the loading window, moves to the left, pushes the bricks onto the roller table 12 and the cycle repeats. Pockets 4 are made with a width equal to the distance plus two thicknesses of the face layer, so the face press powder is poured out of one pocket into two adjacent molds.

After firing a brick, a brick with a protective decorative spoon surface is obtained.
