SU68846A1 - Hydraulic method of peat extraction - Google Patents

Description

Along with the positive aspects of the hydraulic method of peat extraction, which should include the mechanization of the process of excavation of the deposit and the increased productivity of the machines as compared with the methods of extraction of lump peat, this method has a number of significant drawbacks consisting in the bulkiness of the equipment itself and its high metal intensity.

The existing rates of drainage of production sites at hydrohort give a decrease in the moisture content of deposits in the best case to 80-87%. Such a decrease in humidity does not ensure the free maneuvering of all mechanisms involved in the extraction of peat, and a further decrease in the humidity of the deposit leads to an increase in the specific consumption of water for its erosion.

All this makes it impossible to provide normal conditions for the exploitation of peat extraction equipment.

The hydraulic method of peat extraction proposed according to the invention provides for the elimination of the above disadvantages and pe4 Code c. 7

transition to stationary operation during the season of the main mechanical equipment.

The proposal is based on the fluidity property of the hydromass. In the best cases, the content of dry matter in the hydromass is 4-6% with well decomposed peat, and in most cases the dry matter content in the hydromass does not exceed 3.5-4%. Hydromass is a quite fluid fluid and, in the development of a quarry, it moves under the action of the resulting static pressure in the quarry when it is sucked by a peat pump.

This method of peat extraction consists in the fact that the hydromass obtained from the work of the hydro monitors is transported to the pumping peat machines (peat pumps and peat pumps) not through pipes, but through open channels. At the point where the hydromass flows through the open channel, all the machines are concentrated. From this point, the hydromass is supplied by peat pumps to the peat pumps and last to the floor of the spill.

The drawing shows an exemplary diagram of the breakdown of the peat extraction area by the proposed method.

In order to reduce the path traversed by the hydromass, the shape of the production area is made square or as close as possible to the square.

For better flow of the hydromass to the receiving channel of channel 7, the distance between these channels is 100 m.

A mass pipeline collector 2 is constructed in the middle of the entire production site. In the second half of the section, which reaches the site of the deposit to be developed next year, a strip 50 m wide is left for constructing a railway access road 3, a high-voltage transmission line 4, a water-supply channel 5, a communication line and a transit route 9. .

In the center of the mass pipeline collector 2 there is a pumping station 6, which includes peat pumps, peat pumps and high pressure pumps for supplying water to jetting machines 7 through pipelines 8.

All equipment of the pumping station is located on a pile foundation.

Subject invention

A hydraulic method of peat extraction, in which peat moistened with hydraulic monitors is distributed over the fields of a spill using a pump unit through pipelines, characterized in that the hydromass is led from the pit to the pump unit through open channels in order to prevent the peat unit from moving .
