Abstract

The invention relates to the building materials industry and can be used in the manufacture of articles from clay masses by plastic molding. The aim of the invention is to improve the quality of products. The press contains a feed hopper, an inner drum, side discs mounted eccentrically with respect to the inner drum, an arc bracket placed between the side discs, and a device for removing the bar from the pressing chamber. The pressing chamber is provided with an endless movable belt located between the feed hopper and the arc brace, and the side discs have annular cavities on the working surfaces to increase the volume of the pressing chamber. 2 Il.

Description

The invention relates to the building materials industry and can be used in the manufacture of articles from clay masses by plastic molding.

The aim of the invention is to improve the quality of products.

FIG. 1 shows the proposed screwless press; in fig. 2 shows section A-A in FIG. one.

The press contains an inner drum 1 fixed on the drive shaft 2, side discs 3 mounted in bearings 4 on eccentric bushings 5, arc bracket 6 mounted in the lower part of the pressing chamber between side discs 3 on axes x 7 and 8, endless moving belt 9 covering the upper part of the pressing chamber and the envelope of the drums 10 and 11, roller bearings 12, protecting the side discs 3 from axial displacement, the device 13 for removing the beam from the pressing chamber, made in the form of a removable knife, bracket 14, protecting the eccentre slewing sleeves, gear wheels 15, mounted

on the lateral discs 3, the feed hopper 16 and the discharge conveyor 17; The lateral discs 3 have annular cavities 18 on the working surfaces

The press works as follows.

The clay mass from the feed hopper 16 enters the variable cross-section chamber formed by the surfaces of the inner drum 1, side discs 3, the endless moving belt 9 in the upper part of the pressing chamber and the arc bracket 6 in the lower one, is captured and advances to the exit. chambers, it is compacted and outputted by the device 13 in the form of a finished beam to the discharge conveyor 17. The presence on the working surfaces of the side discs 3 of the annular cavities 18 increases the volume of the compression chamber and It enters a larger amount of mass from the receiving bin. This additional mass, as it approaches the exit section, is squeezed out of the cavities by the inner drum 1 and pressed into the layers, mainly adjacent to the surface of the inner drum. This contributes to the straightening of the beam at the exit from

compression chambers and eliminates the appearance of cracks.

By placing between the feed hopper 16 and the arc brace 6 beskoA

In some cases, the movable belt 9 decreases the resistance to movement of the mass, which ultimately improves the quality of the products.
