Apparatus and method adaptable to different fine-grained minerals interfering with sedimentation sorting flow field control

Abstract

The invention discloses a device and method capable of adapting to different fine-grained minerals to interfere with the regulation and control of the sedimentation and sorting flow field. The blades, the upper adjustment side wall board, the lower adjustment side wall board, the upper adjustment mechanism and the lower adjustment mechanism; both sides of the bottom of the rectangular cavity are provided with bottom top water ports, and the bottom top water ports are respectively connected with water inlet pipes. Compared with the prior art, the present invention can be used to adjust the distance between the upper adjustment side wall plate and the side wall of the tapered cavity, the lower adjustment side wall plate and the side wall of the tapered cavity through the upper adjustment mechanism and the lower adjustment mechanism, respectively. The included angle strengthens the side wall flow field and provides side wall sorting effect for the particle group. At the same time, it can adjust the problem that the particle group moves to the middle of the conical cavity and begins to appear chaotic trajectory, so that the fine particles can smoothly pass through the conical cavity. Top edge overflow provides protection.

Description

technical field [0001] The invention relates to the field of separation of different minerals such as coarse coal slime separation and clay mineral separation, in particular to a device and method that can adapt to flow field control of different fine-grained minerals that interfere with sedimentation separation. Background technique [0002] At present, separation equipment based on the principle of disturbance settlement emerges in an endless stream, such as: disturbance bed separator (TBS), cyclone, spiral separator, etc., this type of equipment has no internal power components and completely relies on the disturbance settlement characteristics of the particle group. Classification or sorting, and the movement characteristics of the particle group are formed by the input flow field. Then, how to effectively ensure the stability and timeliness of the flow field during the movement (different sorting positions correspond to the change of the flow field in time), It is of gr...

Problems solved by technology

Although the Chinese patent application number 201420163374.0 is a conical groove slurry sampler, the main problem to be solved is that the sample is uneven and unrepresentative, which leads to inaccurate analysis data, and the device is a single device
