Deep-sea mining valve control type clean water pump ore hydraulic lifting equipment

Abstract

The invention provides deep-sea mining valve control type clean water pump ore hydraulic lifting equipment, which consists of a material storage cabin, a clean water pump, an electric valve, a Venturi ejector, a clock valve, a hydraulic cylinder, an electromagnetic reversing valve, an ore pulp separator, a spraying pipe and a pipeline, wherein the spraying pipe is arranged in the material storage cabin, the clock valve is arranged at the upper end of the material storage cabin, the lower end of the material storage cabin is connected with the electric valve and is arranged on the Venturi ejector, the right end of the Venturi ejector is connected with the electric valve and the clean water pump, and the left end of the Venturi ejector is connected with an ore pulp hydraulic lifting pipeline. The ore pulp separator arranged on the clock valve is used for separating ore pulp, the hydraulic cylinder can be controlled through the electromagnetic reversing valve to close and open the clock valve, and the pressure differences inside and outside the material storage cabin are very great, so a pilot valve is designed in a clock valve piston. Through the control on various valves in the equipment, ores can be mixed into the hydraulic lifting pipeline from the material storage cabin to be lifted to the sea surface. The equipment provided by the invention has the characteristics that the pump lift is high, the weight is light, the flow rate is great, the long-time reliable work is realized, and the like, so the equipment has good application prospects.

Description

technical field [0001] The present invention relates to a deep-sea mining ore hydraulic lifting equipment, in particular to a deep-sea mining ore controlled by a valve to mix ore from a storage bin into a hydraulic lifting pipeline to lift the ore from the seabed to the sea surface Hydraulic lifting equipment. technical background [0002] There are two types of deep-sea polymetallic deposits: manganese nodules and cobalt crusts. Manganese nodules occur on the seabed mud at 3000m-6000m, and cobalt crusts occur on seamounts at 1500m-3000m. According to the estimate of Professor Mero of the University of California, there are 1.7 trillion tons of polymetallic nodules and polymetallic crusts on the bottom of the Pacific Ocean, and polymetallic nodules and crusts contain 70% copper, cobalt, nickel, manganese, iron, tungsten, gold, silver, etc. A variety of elements, including 5 billion tons of copper, equivalent to 9 times the land reserve, 3 billion tons of diamond, equivalent...

Problems solved by technology

[0007] (1) Since the slurry pump works in the deep ocean, maintenance is very inconvenient, so the reliability requirement is high

However, during the use of the slurry pump, there are generally problems such as impeller, volute and other flow-passing parts and ore particles being severely worn, resulting in a short service life of the slurry pump, poor head, efficiency, and cavitation performance of the pump, and reduced sealing reliability of the pump.

[0008] (2) The layout and installation of the slurry pump hydraulic lifting system is very difficult

In order to reduce the wear of the slurry pump, the speed of the slurry pump is generally designed to be low, resulting in a larger size; on the other hand, the head of the single-stage slurry pump is low, and the hydraulic lifting method of the slurry pump must use multiple multi-stage slurry pumps for relay Therefore, the equipment of the hydraulic lifting system of the slurry pump has a large mass and a complex system, and it is very difficult to deploy and install
