Abstract

Use: in the preparation of the mixture of several components of the raw material. SUMMARY OF THE INVENTION: The device comprises a frame on which sieves are fixed one under another. In parallel, the last installed pairs of guides. Runners, equipped with scrapers and connected in an endless chain, are located above the screens. On the runner axles, pairs of stop rollers are mounted, which are in contact with the respective guides. 2 Il.

Description

The invention relates to a clay processing technique and is intended for the preparation of a mixture of several raw materials with different physical properties.

A device for treating clay is known, which contains two hollow drums mounted on a bed with the help of bearing units. The shell of the drum is perforated. The drive rotates the drums in the opposite direction at different speeds to avoid silting the perforations. The gap between the rollers can be changed using a special mechanism 1.

A disadvantage of the known device is the low productivity, since in the gap between the drums there are formed over-compacted clay plates of irregular shape (cakes), which either require additional processing or are sent to waste.

A device for treating clay, selected as a prototype, containing sieves placed one under another, is known.

above each of which are runners connected to the shaft 2.

A disadvantage of the known device is its low productivity, due to the formation of a cake in the gap between the runner and the sieve.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that the known clay processing device, comprising a frame with sieves placed one under another, above each of which are runners, and an actuator, is provided with pairs of parallel guides arranged above each of the sieves and the runners are provided with scrapers and pairs of thrust rollers placed on their axes, each of which is in contact with the corresponding guide, the runners being interconnected by means of elements of an endless chain transmission.

The clay processing device contains a frame 1, on which pairs of parallel guides 2 and sieves 3 and 4 arranged one below the other, drive 5 and tension 6 rotors with an endless chain of hollow runners 7 and scraper 8 are fixed. On the runners 7 axles, thrust rollers 9, each of which is in contact with a respective guide. The tension rotor is equipped with springs 10. Specifically, the device 1 allows the scraper to be set to the required position when passing from the upper tier to the lower one, and the trays 12 direct the spillage for additional processing.

The device works as follows. All the components of the charge are conveyed to the upper rectilinear branch of the chain of runners 7 by means of conveyors and enter the sieve 3 into the gap between it and the runners 7. Freely rotate in the rollers 9, runners 7, thanks to the tensioning device 11 and guides 2, they create a pushing force, stretching and mixing the components of the charge, until the material level decreases to the size of the gap itself between the runners 7 and the screens 3 or 4. At the same time, the scrapers 8 level and pre-mix the material. The material that has passed through the sieve 3 wakes up on the sieve 4 (waking up from the sieve 3 to the sieve 4 enters the tray 12), where the runners 7 move in the opposite direction.
