Nano powder slurry settling tank

Abstract

The invention relates to a nano powder slurry settling tank, which belongs to the technical field of liquid-solid separation of nano powder slurry, and comprises a trough, a stock bin and an upper sloping plate, wherein the trough comprises a left side plate, a right side plate, a front side plate, a rear side plate and a base plate; the stock bin comprises a feeding bin, a settling bin, a baffling bin, an overflowing bin, a discharging bin and a nano powder collecting bin; the upper sloping plate comprises a settling bin upper short sloping plate, a baffling bin upper short sloping plate, a settling bin upper long sloping plate, a baffling bin upper long sloping plate, a feeding bin short clapboard, a feeding bin overflow plate, an overflowing bin overflow plate, a lower large sloping plate, a lower small sloping plate, a support rib plate and slurry channels (A, B, C, D and E); and discharge valves are respectively arranged on two sides of the lower part of the right side plate. When in use, the settling tank can carry out continuous feed and continuous discharge. The nano powder slurry settling tank has the beneficial effects that: the settling speed of the nano powder slurry is fast, and the yield is high; the structural design is reasonable, and nano powder can be completely collected on the bottom part of equipment; the equipment has a small size and is easy to maintain; and the settling tank meets environmental protection requirement without generating any pollution.

Description

technical field [0001] The invention relates to a settling tank for powder slurry, in particular to a settling tank for nano powder slurry, which belongs to the technical field of liquid-solid separation of nano powder slurry. Background technique [0002] The production process of nano powder is, first, the batching process: react various medium additives with various raw materials, remove various useless molecules (impurities), control the content, concentration, and pH, so that the heavy metal nano powder slurry that meets the requirements can be produced The second is the liquid-solid separation process: under the condition that the concentration, specific gravity and slurry shape need to be controlled, the heavy metal nano powder slurry is sent to the centrifuge for solid-liquid separation; the last is the sedimentation process: separated by the centrifuge The nano-powder slurry enters the sedimentation process, and finally the solid particles of the heavy metal nano-p...

Problems solved by technology

As shown in Figure 1, is the square settling equipment correct? The reaction self-gravity settlement process is very common, but the internal structure is unreasonable, the settlement interval is not partitioned, the inclined plate is not designed properly, the settlement rate cannot be designed, there is no flow rate control, the fault is obvious, and the settlement vortex is obvious, which is not conducive to the composition of the settlement chamber. Failed to make better use of the internal production of the settling tank to accelerate the quality and rate of settling; the bottom of the square settling equipment is not equipped with a sloping plate, the structural support is unreasonable, and it is easy to deform; there is no nano-powder collection structure, so that the collection of nano-powder is not easy Thoroughly, the material of the tank body is polluted, which does not meet the requirements of environmental protection
