Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The real-time liquid preparation device for mixing two liquids as shown in fig. 1 mainly comprises a high-level tank 1, a siphon 10, a floating ball 2, a guide rod 6, a guide rod slip ring 5, a fixed rod 8, a fixed rod slip ring 9, a turbine flowmeter 4, a water stop valve 11, a receiver 14, a pipette 17, an electromagnetic flowmeter 16, a water inlet pipeline 15, a reducing pipe 18, a nozzle 20, a negative pressure zone 19, a throat pipe 21, a diverging pipe 22 and the like.

As shown in figure 1, the liquid in the high-level tank is conveyed by a siphon 10, the siphon 10 is connected with a floating ball 2 and a fixed rod sliding ring 9, the floating ball 2 floats on the liquid level and keeps relatively static with the position of the liquid level, the floating ball changes along with the change of the liquid level of dust suppressant solution in the high-level tank 1, so that a guide rod 6 and the siphon 10 also change correspondingly, the fixed rod sliding ring 9 connected with the guide rod 6 also moves along with the liquid level, a liquid level indicating line 7 is arranged on a fixed rod 8, the liquid level change in the high-level tank 1 can be indicated through the fixed rod sliding ring 9, when the solution is less, liquid is added through a liquid adding pipe 3, and the device can be ensured to operate uninterruptedly.

Further, because the siphon tube 10 follows the liquid level to move the same, the liquid level difference 12 between the liquid outlet of the siphon tube and the liquid level is kept constant, so the flow rate of the liquid in the siphon tube 10 is constant and is not influenced by the liquid level change in the head tank 1. When the concentration of the solution needs to be adjusted, the screwing length of a threaded thin tube 13 embedded in the bottom of the siphon 10 can be adjusted to adjust the liquid level difference 12, so that the automatic liquid adding speed is changed. The siphon pipe 10 is provided with a turbine flowmeter 4, and the adjusting degree of the liquid level difference 12 is determined according to the turbine flowmeter 4.

Further, when the liquid distribution is stopped, only the water stop valve 11 at the bottom of the siphon tube 10 needs to be closed, so that the siphon tube 10 is still filled with liquid, and the previous adding state can be directly recovered when the water stop valve 11 is opened again. Below the outlet of the siphon 10 is a receiver 14, through which receiver 14 the liquid added by the siphon 10 enters the pipette 17.

Further, another liquid enters the reducer 18 from the water inlet pipe 15 through the electromagnetic flow meter 16, and the electromagnetic flow meter 16 is used for controlling the liquid inlet speed.

Further, the liquid passes through reducer 18 to nozzle 20, where the velocity increases, and then the high velocity liquid is ejected from nozzle 20 to form a jet. Due to the entrainment of the jet, air and liquid near the nozzle 20 are entrained by the high velocity fluid, a negative pressure zone 19 is formed between the outlet of the nozzle 20 and the throat 21, a pressure differential is created with the environment, and the liquid in the suction tube 17 is carried into the mixing device by the pressure differential and enters the throat 21 with the high velocity fluid.

Furthermore, in the throat 21, the two liquids are subjected to energy and momentum transfer, are primarily mixed, finally enter the divergent pipe 22 at the same speed, form a vortex in the divergent pipe 22, and are further mixed, so that the whole liquid distribution process is completed, and the divergent pipe 22 can be connected with other using devices later.
