SU63585A1 - Probe for measuring the loading level of a blast furnace - Google Patents

Description

On all mechanized blast furnaces, the loading level of materials (charge) is measured by probes. To measure the level of loading into the furnace, an iron rod consisting of a whole piece or of three or four independent sections, screwed together, is lowered. In the course of the furnace, the rods (sediments) rods are bent, often broken and broken. To replace an outdated probe, you have to work in very difficult conditions.

The probe proposed by the present invention for measuring the charging level of a blast furnace is free from these disadvantages due to its inherent resilience. This elasticity is achieved by the fact that it is made of a number of tubes mounted on a tensioned cable.

In FIG. 1 shows a general view of the probe; FIG. 2 shows a detail of fastening the lower tube to the hummock; FIG. 3. - Detail of the top tube.

Each tube 1 (Figs. 1 and 2) is bored down into a cone. Above it is turned on a cone of the same size. The tube 1 is put on the lower end of the cable 3 and is brewed at the bottom at point a. Several transverse, offset along the longitudinal axis of the tube, are drilled in the bottom tube, into which rivets 8 and (rivets) are inserted after welding or before (riveted. As can be seen from Figure 2, the rivets enter the annular gap between the cable and the tube and their tension They create a rigid fastening of the tube with a cable. Above the lower tube (Fig. 3) several washers 9 are put on the cable 3, which are also fastened with rivets, and then the rest of the tubes that are not attached to the cable are put on the cable freely. Fig. 1), on the cable free They are loaded with a load 2, and the last tube 1 is placed on it, above which a tension device is put on the cable, consisting of two washers 10, between which a spring 7 is placed. A bolt 4, a washer 5 and a nut 12 rest on the upper washer 10. Due to the weight and tensioning device, the tubes are pressed against the lower fixed tube, and this achieves a stiffness sufficient to keep the CR probe straight and its free vertical pole.

If the lower tube breaks, the remaining tubes are supported by the washers 9 and the cable can continue (to work. When hitting the stupas with collapsing materials, the gauge is bent, but under the action of

The tensioner and co-weight is rectified again.
