Description

I

The invention relates to the field of engineering and can be used in the briquetting of bulk materials such as salts.

Known roller presses are used for the briquetting of bulk materials, containing rollers, a loading shaft installed by them and a device for venting air from the working zone ll

The disadvantage of such a press is that the soaojrxa removal device in the form of a splitter with wedge-shaped elements does not ensure complete removal of the air displaced by the rolls, which leads to an unstable pressing process, vibration of the rolls and, as a result, a reduction in the quality of briquettes.

The purpose of the invention is to improve the quality of briquettes.

This goal is achieved by the fact that in a roller press for briquetting loose materials, containing rolls, a loading shaft mounted above them and a device for venting air from the working

ZONES, the air exhaust device is made in the form of a vibration exciter, partitions fastened to it and flexible connections for suspension of partitions in the shaft along the rolls.

On the 4th. I depicts a roll press; in fig. 2 is a view A of FIG. one.

The roller press consists of a loading shaft 1, work rolls 2 and a device 3 for air exhaust.

ten

The air exhaust device consists of dividing walls 4 suspended with the possibility of frequent oscillations on the cables 5 in the shaft 1 and located above the rollers 2. The separation walls 15 of the towns 4 are interconnected by means of a rod 6, to the output end of which vibrator 7 is attached.

The upper part of the partitions 4 is free in the cell into the chamber formed by the dissection unit 8, the cavity of which is connected to the suction fan by the tube 9.

Roll press works as follows. in a way.

The initial product enters the shaft 1 and, by means of a streamline the divider 8, enters the pressing zone. The air displaced from it rises up along the surface of the vibrating partitions 4, gets under the divider 8 and further along the tubes 9 is sucked off by a fan. The vibration of the sealing walls 4 contributes to the creation of air channels along their surfaces in order to drain the air displaced during pressing.

The frequency and amplitude of oscillations of the partitions 4, the height of their installation above the pressing zone, as well as the distance between them depend on the physicomechanical pressure of the pressed material.

The connection of the air cavity under the divider 8 with the suction fan creates the necessary discharge not only in this cavity, but also along the surface of the vibrating walls 4, which makes it possible to activate and stabilize the discharge of air from the pressing zone, reduce the flow of the pressed material and improve the quality of briquettes.
