Description

Technical Field

[0001] The invention relates to the technical field of a constant pressure supply device for an electrochemical soft soil solidification system. Background Art

[0002] The current electrochemical soft soil solidification technology uses a water pump to supply liquid to the electrodes through a water pipe. There are the following problems in the liquid supply process: the farther away from the water pump, the less liquid will be discharged, and the closer to the water pump, the more liquid will be discharged, which will cause some electrodes to have too much electrolyte and some electrodes to have too little electrolyte, thus affecting the overall solidification effect. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a constant pressure supply device for an electrochemical soft soil curing system, which has the advantages of simple structure, low cost, being able to supply multiple electrodes at one time, stable liquid supply, and improved curing effect.

[0004] The technical solution adopted by the present invention is:

[0005] The constant pressure supply device of the electrochemical soft soil curing system comprises a mixer, a connecting pipe, a first water pump, a grouting barrel, a second water pump and a main delivery pipe which are connected in sequence; the main delivery pipe is connected in parallel with a plurality of branch delivery pipes; each branch delivery pipe is connected in parallel with a plurality of insertion pipes; the mixer comprises a mixing barrel, an impeller and a motor; the motor is fixedly mounted at the lower end of the mixing barrel, the impeller is arranged inside the mixing barrel and is transmission-connected with the motor; the mixing barrel is provided with a discharge port; the constant pressure supply device of the electrochemical soft soil curing system also comprises a first solenoid valve, one end of which is connected to the discharge port; a connecting pipe, one end of which is connected to the other end of the first solenoid valve; a first water pump, one end of which is connected to the connecting pipe; a grouting barrel, the interior of which is connected to the other end of the first water pump; and a second solenoid valve, which is connected to the lower end of the inside of the grouting barrel.

[0006] A first electronic flow limiting valve is installed on each branch delivery pipe.

[0007] A second electronic flow limiting valve is installed on each insertion tube.

[0008] A third electronic flow limiting valve is installed on the main delivery pipe.

[0009] The first electronic current limiting valve, the second electronic current limiting valve and the third electronic current limiting valve cooperate to adjust and form a constant pressure liquid supply for the entire system.

[0010] A liquid level sensor is installed at the end of each insertion tube to detect whether the electrolyte inside the electrode has a sufficient liquid level, that is, to prevent the problem of lack of electrolyte.

[0011] Each insertion tube is equipped with a color recognition sensor, which can be used to detect whether the electrolyte overflows. If the electrolyte overflows inside the electrode, the color recognition sensor recognizes that the electrolyte of a different color from other colors has overflowed, and the controller receives a signal from the color recognition sensor and controls the electronic current limiting valve at the corresponding position to close until the controller detects that the liquid level inside the electrode is lower than the preset value through the liquid level sensor, and then the controller controls the electronic current limiting valve in the corresponding electrode to open.

[0012] The constant pressure supply device of the electrochemical soft soil curing system also includes a controller, which is electrically connected to the motor, the first water pump, the second water pump, the first solenoid valve, the second solenoid valve, the first electronic current limiting valve, the second electronic current limiting valve, the third electronic current limiting valve, the liquid level sensor and the color recognition sensor.

[0013] The process from stirring to grouting is completed in sequence. During the grouting process, the electronic flow limiting valve is controlled by monitoring the flow rate, thereby achieving the purpose of constant pressure grouting.

[0014] The beneficial effect of the present invention is that the farther away from the water pump, the less liquid output, and the closer to the water pump, the more liquid output, which will cause some electrodes to have too much electrolyte and some electrodes to have too little electrolyte, thus affecting the overall curing effect.
