Detailed Description

Some specific embodiments of the invention will be described in detail below, by way of example and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale.

Referring to fig. 1, the present invention provides a full-automatic chemical feeding sledge, which is connected with three parallel chemical feeding lines after two pneumatic loading pumps are used and prepared, and each chemical feeding line is provided with a chemical feeding tank, a paddle type stirrer, a Y-shaped filter, a double-diaphragm metering pump, a pulsation damper, a safety valve and a check valve. And the other fresh water injection pipe is communicated with the fresh water injection ports of the three dosing tanks and can fill fresh water into the dosing tanks.

Chemical agents are injected into the chemical adding tank 2 through the pneumatic loading pump 1, meanwhile, fresh water is injected into the chemical adding tank 2, and the concentration of chemical agent solution in the tank is controlled in a required proportion by controlling the flow proportion of the chemical agents and the fresh water. The paddle agitator 3 in the tank is then activated to thoroughly mix and mature the chemical solution. The cured chemical agent is discharged from the chemical adding tank 2, impurities are filtered out through a Y-shaped filter 4, and then the chemical agent is added through a double-diaphragm metering pump 5. Set up pulsation damper 6 and relief valve 8 on the two diaphragm metering pump outlet pipeline, the effect of pulsation damper is that add medicine pressure and flow steadily, and relief valve 8's effect is that the pressure release returns chemical agent to in adding the medicinal cupping 2 through relief valve 8 when the pipeline superpressure.

A first manifold and a stop valve 11 are arranged in front of an inlet of a Y-shaped filter 4 of each dosing line, the three dosing lines are communicated with each other at the first manifold, and chemical agents coming out of the selectable dosing tank 2 enter the Y-shaped filter 4 of any one dosing line for filtering.

A second manifold and a stop valve 11 are arranged in front of the double-diaphragm metering pump 5 of each dosing line, the three dosing lines are communicated with each other at the second manifold, and chemical agents after filtration can be selected to be dosed by using the double-diaphragm metering pump 5 of any dosing line.

And a third manifold is arranged at the outlet of the safety valve 8 on each dosing line, and the outlets of the three safety valves 8 are communicated by the third manifold and communicated to the three dosing tanks 2. When overpressure occurs in the pipeline, the safety valve 8 is opened to release the pressure, and the chemical agent can return to any chemical adding tank 2.

Preferably, each dosing line is provided with a pressure gauge 7.

Preferably, each dosing tank 2 is provided with a liquid level transmitter 10.
