SU427868A1 - RING BRIQUETTING PRESS - Google Patents

Description

I

The invention relates to the field of pressure treatment of materials, in particular to devices for the briquetting of bulk materials.

The known ring briquetting press contains two rotating rings mounted on a bed with rotating discs placed eccentrically inside them, as well as a mechanism for pressing the discs to the rings.

The disadvantages of the known briquetting press are relatively large dimensions and significant instability of the rings and discs in the plane of their rotation. As a result, wear of the flanges of the rings and the support rollers is observed. In addition, to limit the movement of the rings in horizontal direction, it is necessary to install restrictive rollers.

Reducing the dimensions of the press and increasing the stability of the rings in the plane of their rotation is ensured by the fact that the mechapism of the clamp is made in the form of two lever systems, each of which contains a rocker arm hinged with one shoulder on the frame, and a rod with a nut at one end hinged to rocker, as well as located in the bed on both sides of the ends of the threaded shtaig disks, on which the mentioned nuts are planted, and

having at one end a gear drive, and at the other - spring-loaded strips.

FIG. 1 and 2 are shown on the proposed press boot device.

The two rings i / and 2 (Fig. 1) are supported on the drive roller 5 and the support roller 4 suspended on the link 5.

Pressing discs 6 and 7 are included in the grooves of rings 7 and 2 and with the help of a lever system including rocker arms 8 and 9, shatuny 10 n //, two nuts 12, 15 (Fig. 2) and two threaded rods 14, 15, hinged attachment to the bed. The rods 14, 15 have gears 16, 17 (fig. 2), mounted on the sliding key, which engage with the drive gear 18 of the disk pressing mechanism.

The rods 14, 15 are supported through the bar 19 on the springs 20, 21. The side stationary walls of the pressing channel 22 formed by the pressing surfaces of the disks and rings, as well as the loading devices, are not shown in the drawing.

Scrapers 23 and 24 are installed at the top of each ring, removing the compressed product from the ring ring.

The press job is as follows.

From the drive roller 3, by means of a friction gear, they are inserted in the rotary ring / and 2, which, together with the support roller 4 and the disks 6 to 7, enter into a closed power circuit. The pressing of the power circuit elements to create pressing forces and torque transfer due to frictional forces on the contact surfaces is carried out by springs 20, 21. The rotation of gear 18 is transmitted to the threaded rods 14, 15 through gears 16, 17. To increase the effort press the discs to the rings by turning the rods to lower the nuts 12, 13, and when they stop, lift the rods and compress the springs 20, 21. The pressed material is fed into the widest part of the pressing channel 22 (shown by arrows 25 and 26). As the ring and disc rotate, the material is rolled and removed in the form of a tape by a scraper 23 (24). When the material is fed unevenly, the disks swing together with the rocker arms 8, 9, increasing or decreasing the minimum clearance between the disk and the ring. In this case, the nuts 12, 13, in combination with the rods 14, 15, move but vertically. When lifting the shthang, the springs 20, 21 are compressed (the gap increases). By increasing the material supply, the minimum clearance between the disk and the ring, as well as the pressing force, is increased due to the greater compression of the springs 20, 21. The subject invention The ring briquette press containing two rotating rings with press disks placed eccentrically placed inside them, as well as the mechanism of pressing the disks to the rings, characterized in that, in order to reduce the dimensions of the press and increase the stability of the rings in the plane of their rotation, the pressing mechanism is made in the form of two lever systems, Each of them contains a yoke, hingedly fixed by one shoulder on the frame, and a rod with a nut at one end, pivotally connected to the beam, and also located in the frame on both sides of the ends of the disks of the threaded rods, on which the said nuts are planted, and having At the end there is a pinion, and on the other side there is a spring strip.
