Seabed ore sand pulling sucker

Abstract

The invention relates to a seabed ore sand pulling sucker, comprising a volute grading cyclone, a high-pressure pump and a jet water gun, wherein an inversion form is adopted for the volute grading cyclone; an underflow opening is formed above the volute grading cyclone, and respectively connected with a raw pulp conveying pipe and a high-pressure water pipe through a tee joint; the high-pressure water pipe led out from the high-pressure pump is additionally communicated with the jet water gun through a tee joint of a rotary sleeve. Compared with the prior art, the seabed ore sand pulling sucker has the beneficial effects that 1) the functions of mining and haling, sand absorbing, sand conveying, concentrate outputting and tailings backfilling are integrated into a whole; 2) raw ore collecting and sorting functions are achieved by using the volute grading cyclone, and the seabed ore sand pulling sucker is high in production rate and beneficial to large-scale production; 3) the haling and pulp conveying functions are simultaneously achieved by high-pressure water jet, and the utilization rate is high; 4) the seabed ore sand pulling sucker is simple in structure, convenient to use and reliable to operate; 5) tailing slurry is discharged by adopting an L-shaped sand discharge pipe, and the ecological environment destruction phenomenon caused by direct emission is avoided.

Description

technical field [0001] The invention relates to a seabed ore deposit mining equipment, in particular to a seabed ore sand removal and suction head which integrates the functions of "mining sand removal, sand suction, sand delivery, concentrate output, and tailings backfill". Background technique [0002] Seabed placer belongs to the seabed mineral resources, which are rich in seabed mineral resources, distributed from the coast to the ocean. Seashore placer deposits have been exploited and utilized by human beings for a long time, and shallow sea oil exploration has spread all over the world's sea areas, and has now expanded to semi-deep sea areas. The reserves of deep-sea manganese nodules and seabed hydrothermal deposits are huge, and the metal-bearing grades are high. As the mining technology matures, it will enter a new stage of developing deep seabed mineral resources. the [0003] At present, the large-scale mining of seabed mineral sand is construction sand and grav...
