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
[0030]
[0031] Embodiments of the present invention are further described below in conjunction with the accompanying drawings, but should not be limited to the following embodiments:
[0032] 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 horizontal dense slurry foam pump system at least comprises an ore slurry defoaming pool with a fluid director and a horizontal dense slurry foam pump, wherein the ore slurry defoaming pool with the fluid director is in transverse fit connection with the horizontal dense slurry foam pump through a rubber flexible joint; foam ore slurry with certain inlet pressure head tangentially enters a work bin formed by the combination of cylinders and a conical tube from a feeding port of the ore slurry defoaming pool with the fluid director, and generates a strong eddy in the ore slurry defoaming pool with the fluid director by virtue of the effect that the pressure head is absorbed by the horizontal dense slurry foam pump; gas is compulsively separated out from the foam ore slurry subjected to centrifugal force, and is discharged through a middle vent pipe; the pre-whirl of the ore slurry is eliminated by the fluid director, and then the ore slurry enters an inlet of the horizontal dense slurry foam pump. According to the invention, a special impeller for the horizontal dense slurry foam pump is adopted, so that the excellent hydraulic performance is demonstrated; the single-stage flux lift of the horizontal dense slurry foam pump system is greatly improved, theoretically, the flux can reach 10000 m <3> / h, the lift is 120 m, the weight concentration of conveyed ore slurry can reach 70%, and the viscosity of the conveyed ore slurry can reach 300 mpa.s; slurry liquid with high bubble content, high concentration and high viscosity can be conveyed; besides, the anti-cavitation performance is remarkably improved, the overall efficiency of the pump is remarkably improved, and the pump can still operate effectively when the supplied materials are insufficient.
Description
technical field [0001] [0002] The invention belongs to the field of rotary power pump equipment transportation, in particular to a horizontal thick slurry foam pump system for transporting a large amount of foam slurry. 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 requir...
