Background
For ore dressing equipment using ore pulp with certain concentration as a feeding material, the ore pulp is required to be guided into the equipment through a feeding pipe, for example, coarse coal slime sorting machine (TCS, TBS), the equipment achieves the effect of material dispersion through a central rotational flow feeding mode, but the feeding mode has the phenomenon that the feeding is uneven or the feeding speed is slow in a pipeline to generate deposition, the feeding mode causes the granularity and concentration distribution of a central area and an edge area in the equipment to be uneven, a product material layer and a sedimentation material layer are interfered, a stable ore pulp flow state cannot be formed inside, the operation difficulty of the system is increased, and the sorting precision and the sorting efficiency are reduced.
Disclosure of Invention
The invention aims to solve the technical problem of providing an ore pulp feeding and equally dividing device aiming at the defects of the feeding mode of the existing ore dressing equipment taking ore pulp with certain concentration as the feeding material.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a device is equallyd divide to ore pulp pan feeding, characterized by it by the pan feeding pipe, the branch pipe, the umbrella emits support and central discharging pipe is constituteed, the pan feeding pipe is the steel pipe of coarse diameter, the branch pipe is the steel pipe of thin diameter, branch pipe and pan feeding pipe intercommunication, the branch pipe structure is the same, the quantity is two at least, and use pan feeding pipe to erect the pipe section and evenly arrange as the center, the branch pipe export is at same horizontal plane and keep the export upwards, the umbrella emits and adopts the steel sheet to enclose the umbrella-shaped structure of certain cone angle, a plurality of through-holes of evenly distributed on the umbrella emits the surface, the umbrella emits and supports and the branch pipe links to each other through the umbrella, pan feeding pipe erects the top of the pipe section and sets up central discharging pipe.
According to the scheme, the diameter of the central discharging pipe is larger than that of the branch pipes, so that the flow rate of ore pulp at the outlet of the central discharging pipe is consistent with that of ore pulp at the outlet of the branch pipes.
Preferably, the feeding pipe is of an L-shaped structure, ore pulp is fed into the equipment from the outside through a transverse pipe section, the vertical pipe section is aligned with or close to a central shaft of the equipment, the transverse pipe section is provided with a certain gradient, the gradient is determined according to the concentration and the flow rate of the ore pulp, and the gradient is positive, so that the ore pulp is prevented from being deposited in the feeding pipe.
Preferably, the branch pipe is of an L-shaped structure, the vertical pipe section is vertically upward, the material flow direction can be ensured to be vertically upward, the horizontal pipe section is provided with a certain gradient, the gradient is determined according to the ore pulp concentration and the flow velocity, and the gradient is a positive value for preventing the ore pulp from being deposited in the branch pipe.
Preferably, the umbrella cap support is composed of three round steel bars, so that the stability of the umbrella cap can be guaranteed, and the space for outflow of ore pulp can be enlarged as much as possible.
Preferably, the cone angle of the umbrella cap is designed according to 90-150 degrees.
The invention brings the following beneficial effects:
the ore pulp reaches the branch pipe and the central discharging pipe through the feeding pipe, vertical upward movement is realized through the branch pipe and the central discharging pipe, and most of the ore pulp changes the movement direction to realize downward movement after the ore pulp touches the umbrella cap. The branch pipes are identical in structure and are evenly arranged around the feeding pipe, the ore pulp pressure at the inlet of each branch pipe is identical, and the resistance of the branch pipe pipelines is identical, so that the ore pulp flow rate and the ore pulp pressure at the outlet of each branch pipe are identical. The diameter of the central discharging pipe is larger than that of the branch pipe, so that the discharging speeds of the central discharging pipe and the branch pipe can be ensured to be the same. The purpose of the umbrella cap opening is to reduce the pressure of the ore pulp at the outlet of the branch pipe and reduce the downward speed of the ore pulp. Therefore, the uniform distribution of the feeding ore pulp at the section of the discharging part can be ensured, and the separation precision and the separation efficiency of the equipment are improved.
The device can realize the uniform distribution of the fed ore pulp, so that the flow field is more stable, the ore pulp only needs one feeding port, the structure is simpler, the installation and the maintenance are convenient, the operation is easy to control, the separation precision and the separation efficiency are improved, the energy consumption is reduced, and the problems in the prior art are solved.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in fig. 1 and fig. 2, the apparatus for evenly dividing ore slurry feeding in this embodiment includes a feeding pipe 4, a branch pipe 3, an umbrella cap 1, an umbrella cap support 2, and a central discharging pipe 5. Pan feeding pipe 4 is the steel pipe of gross diameter, branch pipe 3 is the steel pipe of thin diameter, branch pipe 3 and pan feeding pipe 4 intercommunication, branch pipe 3 structure is the same, the quantity is 4, and use pan feeding pipe 4 vertical section axis to evenly arrange as the center, 3 exports at same horizontal plane and keep exporting upwards, umbrella cap 1 adopts the steel sheet to enclose the umbrella-shaped structure of certain cone angle, a plurality of through-holes of surface evenly distributed are covered to the umbrella, the umbrella cap supports 2 and branch pipe 3 through the umbrella cap and links to each other, 4 standpipe section tops of pan feeding pipe are provided with central discharging pipe 5 and umbrella cap 1, the horizontal height that central discharging pipe 5 exports and umbrella cap 1 and the corresponding position highly uniform that branch pipe 3 exports and umbrella cap 1.
