Problems solved by technology
On the one hand, this method cannot completely eliminate the pre-swirl; on the other hand, this method forces the slurry to reverse, which results in a large loss of energy and a decrease in pump efficiency.
Vertical foam pumps usually use semi-open impellers (closed impellers are more efficient than semi-open impellers), and the efficiency is low

Embodiment Construction
[0029]
[0030] Embodiments of the present invention are further described below in conjunction with the accompanying drawings, but should not be limited to the following embodiments:
[0031] Please see attached figure 1 , a vertical foam pump described in the background technology is given, the pump shaft 13 is distributed in the vertical direction of the material box 1, and the upper end of the pump shaft 13 is positioned on the bearing body 15 above the material box 1 On the internal bearing 14, the lower end of the pump shaft 13 is equipped with an impeller located inside the sheath 24; the foamed slurry entering tangentially from the feed port 11 creates a vortex in the material box (the foamed slurry has a certain angular velocity) , anti-rotation through the left-handed helical guard plate 22, eliminating part of the pre-rotation, entering the sheath 24, the rotating impeller does work, and is sent out through its discharge port 23; the sheath 24 is formed by the pump...

The invention discloses an ore pulp defoaming pool with a fluid director. The ore pulp defoaming pool with the fluid director comprises a material box formed by combining a cylinder with a conic tube, wherein a material inlet is arranged in the tangential direction of the circumference of the cylinder; the lower end of the conic tube is connected with the fluid director; the outlet of the fluid director is connected with a horizontal dense pulp foaming pump, and an air discharge tube is arranged at the center of the material box and used for discharging air separated from foam ore pulp into atmosphere; the ore pulp free of bubbles and prewhirl is provided for the horizontal dense pulp foaming pump; the foam ore pulp generates strong vortex in the material box under the combined effect of an inlet pressing head and a dense pulp foam pump suction pressing head in the material box. Under the effect of centrifugal force, the air is forcedly separated from the foam ore pulp and discharged out through the middle air discharge tube. The ore pulp enters the inlet of the horizontal dense pulp foaming pump after the fluid director eliminates the prewhirl in the ore pulp.
Description
technical field [0001] [0002] The invention belongs to the field of rotary power pump equipment conveying, in particular to an auxiliary equipment for conveying thick slurry foam pump containing a large amount of foam pulp. Background technique [0003] At present, the foam pumps at home and abroad are all vertical foam pumps. The representative foam pumps mainly include the AF series vertical foam pumps of WARMAN Company introduced by Shijiazhuang Water Pump Factory (see figure 1 ), the world-renowned mining machinery company "Metso" headquartered in Finland, produces SALA series vertical foam pumps. The pump head of the vertical foam pump is installed at the bottom of the material box, and the main shaft is a long cantilever structure. In terms of structural shape and long cantilever shaft, the further increase of the pump (flow rate, head) parameters is limited. With the advancement of modern technology, industries such as mineral processing have put forward higher re...
