The foam slurry catcher comprises a material suction chamber, the material suction chamber is fixed with a slurry pool through a support, a discharge hole is formed in the top of the material suction chamber, a plurality of material suction pipes extending to the lower portion of the outer side of the material suction chamber at different angles are arranged on the material suction chamber, and the material suction pipes are communicated with the material suction chamber. The method has the advantage of solving the problem that the material containing the foam gas is difficult to convey in the prior flotation and industrial production.

Description

Device for conveying foam materials

The technical field is as follows:

the utility model relates to a carry foam material's device.

Background art:

the flotation beneficiation process is widely applied, and statistics shows that more than 90% of nonferrous metal minerals are subjected to flotation, and in addition, the flotation process is also used for beneficiation of black metals, precious metals and nonmetals. The prior art adopts a centrifugal slurry pump to convey the foam slurry, and the pump is not designed for conveying the flotation foam, so that the phenomena of incapability of meeting the requirement of conveying capacity, cavitation erosion of the pump, slurry overflow of a slurry pool, unstable operation, easy damage and the like frequently occur in the actual operation. In addition, when the centrifugal slurry pump conveys slurry containing gas, the performance, flow, lift and efficiency of the pump are greatly reduced, damage to a flow passage part of the pump is aggravated, and even the pump cannot work normally.

The invention content is as follows:

the utility model aims to solve the technical problem that a carry device of foam material is provided, it is fit for carrying the foam material, has solved the problem that carries in present flotation ore dressing and industrial production and contain the foam gas material difficulty.

The above object is achieved by: the slurry pump comprises a slurry pump, wherein an inlet of the slurry pump is connected with a material outlet at the bottom of a slurry pool through a pipeline, an outlet of the slurry pump is connected with a water inlet of an ejector through a pipeline, a foam slurry catcher is arranged in the slurry pool, and a discharge hole of the foam slurry catcher is connected with a suction hole of the ejector through a pipeline.

The foam slurry catcher comprises a material suction chamber, the material suction chamber is fixed with a slurry pool through a support, a discharge hole is formed in the top of the material suction chamber, a plurality of material suction pipes extending to the lower portion of the outer side of the material suction chamber at different angles are arranged on the material suction chamber, and the material suction pipes are communicated with the material suction chamber. When the suction pipe works, the suction pipes extend to different angles, so that foams at all parts in the ore pulp tank can be sucked into the suction chamber.

The utility model has the advantages that: the design of the device accords with the characteristics of hydrodynamics and physics, materials containing foam are conveyed by negative pressure, liquid water in the materials is conveyed by a slurry pump, the lower part of a slurry pool is water, the upper part of the slurry pool is foam materials, the slurry pump is arranged at the lower part of the slurry pool, when the slurry pump works to convey water in slurry, as the outlet of the slurry pump is connected with an ejector, the slurry pump works to generate certain pressure, water with certain pressure and flow rate enters a Laval nozzle of the ejector, high-speed ejection is carried out, the pressure energy is converted into speed energy to generate vacuum, the foam materials at the upper part of the slurry pool enter a mixing chamber of the ejector under the action of vacuum through a catcher, the foam materials are mixed and compressed with high-speed water flow in the mixing chamber to crush the foam, the foam materials are decelerated through a Venturi tube of the ejector and discharged in a pressurizing manner to achieve the purpose of conveying foam gas of the slurry, slurry containing foam of concentrate materials is mixed and, the foam is broken and then conveyed away together with the concentrate. Therefore, the foam material conveying device has the advantages of remarkable energy-saving effect, reasonable design, small maintenance amount and durability, is particularly suitable for conveying foam materials, solves the problem that the conveying of the materials containing foam gas is difficult in the existing flotation and industrial production, has good use effect and high work efficiency, and is an ideal foam material conveying device.
