Description

The invention relates to the mining industry and can be used to destroy rocks, compact loose soil and as a source of seismic waves.

The purpose of the invention is to increase the efficiency by intensifying cooling while increasing the efficiency of the device and reducing metal intensity.

The drawing shows a device for the destruction of rocks.

The device for destruction of rocks comprises a housing 1 divided by a piston brisk 2 into an expansion chamber 3 and a platoon chamber 4. At the upper end of the housing 1, a combustion chamber 5 is installed, where the inlet valve 6 and the ignition plug 7, as well as the block valve 8 in the lower part, are located in the upper part. On the side of the device case 1, exhaust ports 9 and channels 10 for supplying compressed air are provided. A working tool 11 is placed at the lower end of the housing 1. A cooling jacket 12 with an ejection valve 13 and an annular piston 14 is located inside having through throttling openings 15 located around the combustion chamber 5.

cooling pipes are connected by hoses 16 and 17c to a heat exchanger 18. Around the expansion chamber 3 there is an exhaust chamber 19c with an annular piston 20 rigidly connected to the piston 14. The chamber 19 is provided with exhaust holes 21 in the upper part and communicated in the lower part with outlet ports 9 and a chamber 4 platoons The annular piston 20 is rigidly connected to the annular piston 14 of the rod 22. The annular piston 20 is placed between the openings 9 and 21. The ejection valve 13 is installed in the channel 23 connecting the piston cavity 24 of the cooling jacket 12 to the heat exchanger 18.

A device for destroying rocks works as follows.

The device is exposed to the rock formation B of the coking chamber 4 through the channel 10, compressed air is supplied, and the piston head 2 rises to its extreme upper position. Pressure-air mixture is supplied to the combustion chamber 5, which opens the inlet valve 6. The latter, in turn, will act on the blocking valve 8, thereby isolating the combustion chamber 5 from the expansion chamber 3.

After the combustion chamber is filled with the fuel-air mixture, it ignites from the spark plug 7. At the same time in the chamber 5 of the combustion pressure increases sharply. The block valve 8 opens and the fuel / air mixture enters the expansion chamber 3, begins to move the firing piston 2 down, which strikes the tool 11. When opening the exhaust piston 2, the exhaust gases 9 go into the exhaust chamber 19 on the annular piston 20 and on the piston 14 connected with it by the piston rods 22, forcing them to move upwards. In this case, the movement of the piston 14 through the ejection valve 13 is heated, the water is discharged through the hose 16 into the heat exchanger 18, and the cooled water flows from it through the hose 17 into the cooling jacket 12.

In the upper position, the piston 20 opens the exhaust ports 21 and the exhaust gases leaves the expansion chamber 3.

After exhausting the exhaust gases, the pistons 14 and 20 under the action of gravity sink to the initial position, while the water in the water cooling chamber passes through the throttling holes

15, and the ejection valve 13 is closed.

Thus, with each blow, a partial replacement of the already heated water in the cooling jacket 12 with that cooled from the heat exchanger 18 occurs.

this uses exhaust gas energy to force coolant to circulate, which increases the efficiency of the device.
