(54) DRUM FOR DETERMINATION OF MECHANICAL PROPERTIES OF COKE

one

This invention relates to the coke industry and is intended to determine the mechanical properties of coke.

A drum is known for determining the mechanical properties of coke, comprising a horizontal drive shaft, two side discs and a set of round rods arranged along forming discs with a certain gap. Through the gaps between the rods, pieces of coke that form when determining its mechanical properties in a rotating drum 1 fall through.

The disadvantage of the known drum is the fastening of the rods in the discs with the help of nuts placed on the threaded ends of the rods. When the rods are abraded during work, their replacement and the development and assembly of the drum associated with it takes considerable time (252 connections on the thread).

The aim of the invention is to reduce the time of assembly and disassembly of the drum.

The goal is achieved by the fact that in the drum for determining the mechanical properties of coke, consisting of two disks fixed on a horizontal shaft, between which are placed with a rod gap, provided with means of fastening in disks, the means of fastening consist of an elastic tension element placed in annular grooves made on the ends of the rods protruding from the discs.

FIG. 1 shows a drum, a general view; in fig. 2 - the same, top view; in fig. 3 shows the node I in FIG. one; in fig. 4 - the same, top view; in fig. 5 shows section A-A in FIG. four; in fig. 6 is a section BB in FIG. four.

The drum contains two disks I fixed on shaft 2, rod 3, two elastic tensioning elements, for example cable 4, tension device 5, stops 6 to prevent the disks from displacing and possibly breaking their parallelism relative to each other.

The drum is assembled as follows.

Two discs 1 are mounted on shaft 2 and rigidly fixed. In the hole, located 2Q. along the generators of the disks, insert a rod from the side of any disk. The diameters of the holes are equal to the diameters of the rods with a small gap.

Cable 4, woven in the form of a ring and laid in the circular grooves of the rods. they are fixed in the discs with the help of a tension device 5. There are only two cables on both sides of the drum. After a certain period of time, the rods will wear out and must be replaced with new ones. To replace them, it is necessary to loosen the tension of the cables, remove the worn rods, insert new ones into the holes of the discs and fix them with a cable with the help of a tension device. Tests of the proposed drum showed the reliability of his work and a reduction in the time for assembling and disassembling the drum. If earlier, replacement of the rods required the time spent by 2 mechanics for 36 hours, now this operation is performed by one person for an hour.
