Rapid self-operated mixing device and mixing method

Abstract

The invention discloses a rapid self-operated mixing device and a rapid self-operated mixing method. The rapid self-operated mixing device comprises a first barrel, a second barrel, a third barrel, apartition board, a power transmission mechanism, a power device, a water pressure difference acquisition unit and a controller, wherein the third barrel is coaxially mounted inside the first barrel; the second barrel runs through the first barrel and is connected with the inner cavity of the third barrel; small holes are distributed in the surface of the third barrel; the partition board is connected into the third barrel in a sliding manner; the power transmission mechanism is arranged inside the first barrel and the third barrel; one end of the power transmission mechanism is connected to the partition board, and the other end of the power transmission mechanism runs out of the first barrel and is connected to the power device arranged outside the first barrel; the water pressure difference acquisition unit is used for acquiring a water pressure difference deltaP value between the interiors of the first barrel and the third barrel; a deltaP value signal is transmitted to the controller. Rapid self-operated mixing of a fluid in a water mixing device in a low-flow and low-flow rate state, especially in a laminar flow state is achieved, parameters after mixing can be guaranteed to be quickly detected and fed back, and precise and timely adjustment of a mixing system is facilitated.

Description

technical field

[0001] The invention relates to the technical field of fluid mechanics, in particular to a rapid self-operated mixing device and a mixing method, which are suitable for rapid mixing of two fluids. Background technique

[0002] When two different liquids are mixed online, due to the change of the mixing ratio and the total flow rate, a large change often occurs. Especially for projects that are put into production in stages, the pipeline installation is generally designed and constructed according to the final scale, and the pipeline is much larger than the initial production. When two fluids need to be mixed, the flow velocity in the pipeline is extremely low, especially for the fluid with a small mixing ratio, the flow velocity is even lower. The two fluids mixed through the tee cannot be fully mixed in time, resulting in inaccurate detection of mixing parameters and affecting the adjustment of the mixing ratio of the system. In order to accurately detect ...

[0040] The structural representation of the fast self-operated mixing device of this embodiment can be found in figure 1 , which includes a first cylinder 1, a second cylinder 2, a third cylinder 3, a partition 4, a power transmission mechanism 5, a power device 6, a guide and limit mechanism 7, a first pressure sensor 8, a second pressure sensor Sensor 9 , structural support 10 and controller 11 . In this embodiment, the first cylinder 1 , the second cylinder 2 , and the third cylinder 3 are all cylindrical cylinders, and the first cylinder 1 has the largest diameter. The third cylinder 3 is installed coaxially inside the first cylinder 1 , and the third cylinder 3 is fixed by a structural support 10 . Obviously, the length of the first cylinder 1 is longer than that of the third cylinder 3 . Both ends of the first cylinder 1 are open, one end is the inlet of one fluid, and the other end is the outlet of the mixed fluid. B...
