Abstract

This invention relates to a gas pulse technique and is intended for the destruction of rocks during the hydroproduction of minerals, as well as various solidified deposits in metallurgy, power engineering and other industrial fields. The purpose of the invention is to increase work efficiency due to a more complete use of the energy of the shock wave. The impulse includes a housing (K) 1 with a nozzle 3 and exhaust openings 2 in the front part and an end cover 4. In the cavity K 1 there is a valve 5, which is pressed by spring 6. In the rear part K 1, channel 7 is made, which communicates through nozzle 8 the internal capped cavity K 1 and the internal cavity of the hydraulic cylinder (HZ) 9. In the latter, there is a firing piston 10, which is preloaded inside the HZ 9 by a spring 11, and outside by a fixing nut 12. Water entering K 1 is exhausted from the exhaust ports 2 and nozzle 3 and carries along the valve 5, compressing the spring 6. By reached 5 and the exhaust valve holes 2 are overlapped, and water hammer occurs. In this case, the fluid entrained by the direct wave, under high pressure, through the nozzle 3 is ejected onto the object of destruction. 1 il.

The invention relates to hydro-impulse technology and is intended for the destruction of rocks during hydro-mining of minerals, as well as various solidifying deposits in metallurgy, power engineering and other industrial areas.

The purpose of the invention is to increase the work efficiency due to more complete use of the energy of the shock wave.

The drawing shows a hydraulic pulse, longitudinal section.

The impulse consists of a housing 1, in front of which exhaust holes 2 are made and face nozzle 3 is located, and in the rear part there is a face-lock 4. Inside valve 1 there is a valve 5, preloaded by spring 6, In the back part of housing 1 there is a channel 7, which through the pipe 8, it connects the internal shut-off strips of the housing 1 and the internal cavity of the hydraulic 9, in which the firing piston 10 is located, which is pressed by the spring 11 inside the horizontal and the fixing nut 12 on the outside of the shchindra.

The pulse works as follows.

The working fluid through the end cap 4 enters the housing 1 and through the channel 7 and the nozzle 8 into the hydraulic cylinder 9. The water entering the accumulator 1 flows out of the exhaust ports 2 and the nozzle 3 and simultaneously carries the valve 5 (moves it forward through the drawing to the right), compressing the spring 6.,

When the valve 5 reaches the exhaust ports 2, they overlap, resulting in a hydraulic shock. At the moment of a hydraulic impact, the fluid entrained by the direct wave, under high pressure, is thrown through the nozzle 3 onto the object of destruction. At the same time, at the moment of a hydraulic shock G11 under high pressure, driven by the shock wave, it moves in the opposite direction through the end cover 4, as well as through channel 7, branch pipe 8 and hydraulic cylinder 9, and acts on the piston head 10. The piston head 10 moves forward ( by

drawing to the right), compressing the spring 11, and exerts a shock load on the object of destruction.

After the occurrence of a water hammer and the propagation of shock waves during

The internal cavity of the housing 1 decreases in pressure. The valve 5 under the influence of the spring 6 is rejected - in the opposite direction (according to the drawing to the left), opening the exhaust

holes 2.

Piston head 10 in the hydraulic cylinder 9 - under the influence of the spring 1 also throws in the opposite direction (in the drawing to the left) at a distance,

limited by fixing nut

12. The mechanism is thus brought to its original position. Then, the process: cc is repeated.
