Abstract

The invention relates to equipment for underwater mining of a sludge-like substance, mainly therapeutic mud from small-scale watered fields. The goal is to extract from fields of conditional moisture treatment and increase the degree of development of the entire field, Zi For this case 1 has a through-shaft in length. It contains the main and additional storage tanks (PH) 17 and 18, which are made without a bottom and are equipped with pipes for air supply, which are connected via a flexible hose to a compressor through a valve. An electric hoist 25 located on the crane beam, the PH 17, 18 is lowered into the deposit of dirt. To ensure their immersion, a short-term supply of air is carried out. The flexible hose 13 is lowered into the PH 17, and a vacuum is created in the storage tank, and water from the PH 17 is pumped into it. Then a vacuum is created in the second storage tank. At the same time, air is supplied to the PH 17 and intensive mixing of the dirt with the remaining water is carried out until a homogeneous mass is obtained. Then, from the PH 17 by the sleeve 14 with the nozzle 15, the conditioned dirt is pumped to the collection tank. 6 Il. (L CA SL at 01 4J 4

The invention relates to floating devices intended for subsea mining of sludge-like matter, mainly therapeutic mud from spillway flooded sites.

The purpose of the invention is to extract from the fields of conditionally humid therapeutic mud and to increase the degree of development of the entire field.

FIG. 1 shows a device, side view; in fig. 2 - the same, top view; Fig, 3 - then. same, front view; in fig. 4 - tanks, general view; in fig. 5 - Corus pontoon, side view; on. FIG. 6 is a section A-A in FIG. five.

 The device includes a housing 1 having a through shaft in length, formed by two rigidly connected pontoons 2, divided by internal partitions 3 into separate sections, which are storage tanks for water 4 and conditional dirt 5, in which sensors 6 are installed, the upper part is connected via valves 7 through pipelines 8, and 9, a vacuum pump .10 and a compressor. 11-, stop valves 12, flexible hose

13 with open suction and flexible hose

14 with a hydraulic suction nozzle 15 having a control handle 16, a main 17 and an additional 18 tanks, made without a bottom and equipped with pipelines 19 and 20, connected through a valve 21 by a flexible hose 22 to a compressor 11, a frame 23 - with a crane-beam 24, an electric hoist 25, electric winch 26 and 27, rotating drum 28 with electric cable, switchboard 29.

The device works as follows.

With the reservoir Nm 17 and 18 elevated above the water, the device is transported to the field site chosen for development and oriented along the longest length of the site, by the Electric Tel 25, located on the crane-beam 24, the main 17 and the additional 18 tanks are lowered into the underlying soil . To facilitate their immersion from the compressor 11 through the flexible hose 22 through the valve 21 a brief, temporary supply of compressed air through the pipeline 19 is performed.

By using tanks, it can be realized automatically with a sound recorder 30, I give a signal to stop the electric hoist through an actuator 31 built into it.

The flexible handle 13 is lowered into the main tank 17, and in the storage tank 4 a vacuum pump 10 creates a vacuum and, when a sufficient value is reached (60-70%), water is pumped from the tank 17 to the tank 4 to a predetermined level therein. Thereafter, the tank 4 is turned off and a vacuum is created in the storage tank 5, at the same time air is supplied from the compressor 11 to the tank 17 through the pipe 20 and intensive mixing of the dirt with the water to

obtaining a homogeneous mass.

Next, the flexible hose 14 with the hydro-aspirating nozzle 15 is lowered into the tank 17 and the conditioned dirt is pumped into the accumulative tank 5 due to the vacuum maintained in it by the working vacuum pump 10. The dirt is pumped to the underlying soil without . Then the flexible sleeves 13 and 14 are lifted, the developed tank 17 by the electric hoist 25 is removed and the crane beam 24 is removed. into the free slot of the through shaft of the housing to the next operating position (as the device moves),

The cable of the rear electric drive 26 clings to the loop of the rearranged ret of the tank (not shown), the drive of the electric winch 26 is turned on, and as the cable is pulled, the device moves forward relative to the tanks 17 and 18 by a distance equal to the length of one tank. When the device takes up a new position, the pumping out of the dirt from the additional tank 18 is carried out with the repetition of all the indicated operations in the same sequence.

The control of filling the accumulator with water or dirt automatically detects the signal for stopping the vacuum pump 10. The empty containers 4 and 5 are emptied by supplying compressed air from compressor 11 through line 9 through pipelines 32.

In this case, the water is returned back to the reservoir, and the dirt is pumped into a special floating vessel standing at the side of the device.

The device performs a straight-line directional movement, having carried out a uniform along the entire length of the section, the development of the deposit according to the shuttle pattern. Moving it to the next development belt is carried out with raised tanks either by a self-propelled barge, or manually in poles. The device moves in the opposite direction using a second electric winch 27 for this.

All power units of the device are powered from the switchboard 29 connected to the coastal substation by an electrical cable laid on the rotating drum 28.
