Detailed description of the invention
Below in conjunction with accompanying drawing, some embodiments of the present invention are further introduced, but be not intended to limit protection scope of the present invention.
Comparative example 1: the concentration equipment of prior art
Fig. 1 is the structural representation of a kind of concentration equipment of the prior art, schematic diagram when wherein Fig. 1-1 is this concentration equipment absorption magnetic-particle, schematic diagram when Fig. 1-2 is this concentration equipment release magnetic-particle.
Prior art concentration equipment as Figure 1-1 comprises permanent magnet (4), be enclosed within the nonmagnetic glass cloth (7) on permanent magnet (4) actively, and first container (9) of mixture suspension (5) for splendid attire magnetic-particle and non-magnetic particle.Permanent magnet (4) has the first magnetic pole (2) and the second magnetic pole (1).Connecting rod (8) is made up of non-magnetic material, and its one end connects permanent magnet (4), and the other end has shank.When cover has the permanent magnet of glass cloth (7) (4) to be placed in described mixture suspension (5) absorption magnetic-particle, first magnetic pole (2) and the second magnetic pole (1) are all positioned at below the liquid level of described mixture suspension (5), and the magnetic-particle in mixture suspension (5) is adsorbed on sidewall (6) place of (3) place, bottom corresponding to the glass cloth (7) of the first magnetic pole (2) and the glass cloth (7) corresponding to the second magnetic pole (1).
After absorption magnetic-particle, keeping the second container (10) being moved into the magnetic-particle suspension (5 ') being used for splendid attire magnetic separation under the constant condition of the relative position of permanent magnet (4) and glass cloth (7).Applying pulling force to the shank of connecting rod (8) makes permanent magnet (4) move up in glass cloth (7), until permanent magnet (4) leaves magnetic-particle suspension (5 '), thus the magnetic-particle at (3) place, release bottom.
When permanent magnet (4) moves up, the part magnetic-particle accumulating in sidewall (6) place can move up and keep being adsorbed on sidewall (6 ') place under the attraction of the second magnetic pole (1).When shifting out permanent magnet (4) and glass cloth (7) from second container (10), the magnetic-particle at sidewall (6 ') place also may shift out second container (10) and lose.Like this, when carrying out Armco magnetic iron mensuration as used this concentration equipment, the preci-sion and accuracy of acquired results is poor.
Embodiment 1: concentration equipment of the present invention
