Description

(54) DEVICE TO DESTROY MOUNTAINS

The invention relates to the mining industry and is intended for the hydraulic destruction of rocks.

A device for destroying rocks is known. It includes a trunk and a nozzle, while solid bodies are introduced into the water jet, and sand 1 is used as them.

A disadvantage of this device is that the strength properties of sand are equal to the strength of the rock to be destroyed, as a result of which the destruction efficiency of the bottom hole is reduced.

Closest to the proposed device is a device for destroying rocks, including a barrel with a nozzle and a mechanism for harming solids in a stream of water connected to the barrel and made in the form of a file 2.

The disadvantage of this device is the impossibility of reuse of solids, which reduces its efficiency.

The purpose of the invention is to increase the efficiency of the device when using metal balls.

The goal is achieved by the fact that the device includes a barrel with a nozzle

BREEDS

and a mechanism for introducing solids into the jet of water associated with the stationary wall is equipped with a system for collecting and feeding metal balls made in the form of a sequentially installed tray, separator and elevator and communicated by means of a nozzle with a mechanism for introducing solids into the jet of water.

In the device, the mechanism for introducing solids into the water jet is made in the form of a bunker with two gates and a discharge valve.

FIG. 1 shows the device, a general view; in fig. 2 - mechanism for introducing solids into the water jet, section. A device for destroying a mountainous genus includes a barrel 1, a nozzle 2, a sump 3, a mechanism for separating solids from pulp, made in the form of a magnetic separator 4, a mechanism for introducing solids into a water jet consisting of a hopper 5 with a bottom 6 and top 7 slides,

20 of the receiving part 8 of the bunker, the feeding part 9 of the bunker, a transporting mechanism consisting of an elevator 10 and an inclined nozzle 11. The bunker 5 also has a crane 12 and a discharge port 13 through which the steel balls 14 enter the barrel 1 and the nozzle 2, the Device It also includes a pump 15, an inclined tray 16, a slurry pump 17 and a pipeline 18. The device works as follows. Water through conduit 18 flows to pump 15, from where it is fed under pressure into barrel 1, then through nozzle 2 is sent to bottom. In this case, from the bunker 5, with the lower gate 6 closed, the steel balls 14 are fed through the discharge opening 13 into the nozzle 2 and, together with the water jet, fly out at high speed towards the bottom. The face is destroyed simultaneously due to the action of mechanical and hydraulic action. Repulsed from the rock mass, together with steel balls 14, is washed off with water and along the inclined tray 16 enters the magnetic separator 4, which separates the steel balls 14 and sends them again to the hopper 5 using the elevator 10 and the inclined nozzle 11, and rock pieces together water remains in the sump 3, from where the sludge pump 17 is removed. Thus, the steel balls 14 are returned, they enter the bunker 5 and accumulate in the receiving part 8 on the lower gate 6. After feeding and the part 9 of the bunker is freed from the steel balls 14, close the gate 7 and open The gate 6 is brought in, the balls 14 from the receiving part 8 of the hopper 5 are fed again into the feeding part 9, then the sponge 6 is closed again and the sponge 7 is opened and the cycle is repeated. When operating in the feed, part 9 of the bunker., Ra 5 direct the water under pressure and regulate the flow of water with balls 14 into the standing water with the help of a tap 12. The proposed device improves its efficiency by reusing metal balls introduced into the jet water. An invention of a device for breaking rocks, comprising a barrel with a nozzle and a mechanism for introducing solids into a stream of water associated with the barrel, characterized in that, in order to increase the efficiency of the device when using metal balls, it is equipped with a system for collecting and feeding metal balls made in the form of a sequentially installed tray, separator and elevator and communicated by means of a nozzle with mechanisms for introducing solids into the water jet. 2. An apparatus according to claim 1, characterized in that the mechanism for introducing solids into the water jet is made in the form of a bunker with two valves and a discharge window.
