Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-3, the device for eliminating the surface layer foam of the self-feeding direct-flushing thickener comprises a thickening tank 1, a submersible pump 3, a semi-closed rubber pipe 4 and a trash discharge port 6, wherein a truss 7 is arranged at the top of the thickening tank 1.

The submersible pump 3 is arranged in the clear liquid above the clear belt 2 of the thickening tank 1, the outlet pipe of the submersible pump 3 is connected with the semi-closed rubber pipe 4, and the clear liquid in the thickening tank is conveyed to the semi-closed rubber pipe 4 through the submersible pump 3. The supply is to the water of semi-closed rubber tube 4 for the water of clarification area in the thickening pond, need not cite the clear water, practices thrift the cost, and uses the clarification liquid in the thickening pond to act as the defoaming water, can not influence the concentration of dense ore pulp. The submersible pump 3 does circular motion along with the thickener truss, so power needs to be supplied by a sliding axis, and when the semi-closed rubber tube 4 is blocked by the circular hole spray head 5 or the water pumping amount of the submersible pump 3 is too large, the mounted overload protection plays a role in protecting the whole device.

The semi-closed rubber tube 4 is horizontally fixed through a truss 7, and a round hole spray head 5 is arranged on the side of the semi-closed rubber tube facing the liquid surface of the thickening tank; clear liquid conveyed by the submersible pump 3 is conveyed to the semi-closed rubber pipe 4 and is sprayed to a foam layer of the thickener by the round hole spray head 5, and the foam is dispersed and broken by impact, so that the defoaming effect is realized; meanwhile, valuable metals are separated from the foam layer and sink into the dense layer. When the thickness of the foam layer changes, the opening degree of a valve at the inlet end of the semi-closed rubber tube 4 can be adjusted through adjustment, so that the water pressure of the flushing water is adjusted, the concentrate precipitation is accelerated, the concentrate loss is reduced, and the concentration efficiency is improved.

The height of the semi-closed rubber tube 4 from the foam layer is as follows: 30-40cm, the diameter of the round hole nozzle 5 is 0.6cm, and the hole distance is 3-5 cm. The size design is designed according to the viscosity, the surface tension and the like of the foam in the current flotation process of the nonferrous metal ores, and the elimination rate of the size foam can reach more than 80 percent through experimental verification.

The end of the semi-closed rubber tube 4 is connected with the impurity discharging port 6 through a bolt, impurities are discharged, the end of the semi-closed rubber tube 6 is provided with a discharge valve 8, and the discharge valve 8 is preferably a ball valve in view of the rapid opening and closing property of the ball valve. When the semi-closed rubber tube 4 is blocked or overhauled, the discharge valve 8 at the tail end of the impurity discharge port 6 is opened, impurities in the semi-closed rubber tube 4 can be thoroughly and quickly removed through the discharge valve 8, and when the impurities are discharged, the discharge valve 8 is closed, so that defoaming operation can be recovered.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
