[0046] The device can be used to compound and dilute the release agent with water to quickly obtain a uniform and dilution-stable release agent diluent, and can also be used in the case of automatically mixing two liquids with different functions according to the proportion and then using them.

[0047] The working principle of the device will be briefly described by taking the dilution of the release agent with water as an example. During operation, the release agent and water are added into the two tanks from the filling ports at the top of the tank 1 and the tank 2. The flow rates of the flow pump 4 and the flow pump 5 are set by adjusting the rotation speeds of the flow pumps, so as to control the mixing ratio of the release agent and water. At the same time, the flow pump 4 and the flow pump 5 are started, the release agent and water are pre-mixed in the Y-shaped three-way pipe 6 through the respective flow pumps and hoses, and then the pre-mixed liquid is further mixed in the mixing tank 8. The pre-mixed liquid flows into the impeller 8-5 from the liquid inlet 8-3, and impinges on the fan blades between the rotating shaft 2 8-61 and the rotating shaft 3 8-71 under the guidance of the protrusions 8-8, so that the impeller 2 8-6 and the impeller 3 8-7 are rotated in opposite directions. The mixed liquid is uniformly mixed under the high-speed rotating disturbance of the impeller 1 8-5, the impeller 2 8-6 and the impeller 3 8-7, and flows to the spray gun from the liquid outlet 8-4 for spraying.

[0048] When the central controller 11 is not provided, the flow rates of the flow pump 4 and the flow pump 5 are set by adjusting the rotation speeds of the flow pumps, so as to control the mixing ratio of the two liquids. When the liquid level in the tank 1 or the tank 2 decreases to the warning value, the flow pump 4 and the flow pump 5 are stopped at the same time, and the flow pumps are restarted after the liquid is replenished to continue the spraying.

[0049] When the central controller 11 is provided, the rotation speeds of the flow pump 4 and the flow pump 5 are set on the central controller 11, so as to control the mixing ratio of the two liquids. When the liquid level in the tank 1 or the tank 2 decreases to the warning value, the corresponding liquid level sensor 9 or the liquid level sensor 10 sends a signal to the central controller 11, and the central controller 11 simultaneously disconnects the power supply of the flow pump 4 and the flow pump 5. After the liquid is replenished, the liquid level sensor sends a signal to the central controller 11, the central controller 11 restores the connection between the flow pump 4, the flow pump 5 and the power supply, and then the flow pumps are started to continue the operation.

[0050] In the embodiment, the discharge amounts of the release agent and water (i.e. the mixing ratio of the two) are controlled by adjusting the rotation speeds of the flow pumps. In other applications, suitable liquid pumps can be selected according to the properties of the liquids, such as the corrosion, viscosity, etc., and the discharge amounts of the liquids can be controlled by adjusting the rotation speeds, blade angles or opening degrees of the inlet and outlet valves, etc.
