It is used to measure the liquid level.

[0015] Please continue reading Figure 1As shown, in one embodiment of the utility model, the water inlet 4 includes a water pipe 41, which is arranged in the drug dissolving box 1, and the cross section of the water pipe 41 is Z-shaped. The water pipe 41 is provided with a solenoid valve 42 and a flow meter 43. The solenoid valve 42 is a normally closed type, and the water inlet flow value is set according to the dosage of the drug and the required dissolution concentration. The drug adding port and the emptying port are connected to each tank by the water pipe 41, which is convenient for operation needs.

[0016] Please continue reading Figure 2 As shown, in one embodiment of the utility model, an electric screw conveyor 21 is provided in the medicine storage hopper 2, and the electric screw conveyor 21 is provided at the inner bottom of the medicine storage hopper 2.

[0018] The working principle of the utility model is as follows: when the medicine storage hopper is filled with powdered medicine, the control system opens the water inlet solenoid valve according to the programming steps of the control program, and clean water enters the medicine dissolving box through the water inlet flowmeter. The water inlet time is set according to the water flow rate. When the water inlet time reaches the set value, the dissolving tank agitator, the electric screw conveyor, and the vibrator (operating intermittently according to the designed time) are started, so that the medicine is quantitatively and evenly added to be fully stirred and dissolved; when the liquid level rises to the medicine hole of the partition, it overflows to the maturation tank for further mixing and reaction; when the mixed medicine liquid rises to the medicine hole of the partition, it overflows to the storage tank; when the liquid level rises to the intermediate liquid level meter, the agitator The mixer and the dosing pump are started, and the liquid medicine is evenly stirred and transported to the required locations, thus completing the entire dosing process cycle; when the level meter alarms, it reminds you to add powdered medicine to the medicine storage hopper to ensure that there is enough storage volume; when the liquid level in the storage tank rises to the high liquid level meter, the water inlet solenoid valve is closed, and the electric screw conveyor stops at the same time. If the solenoid valve fails, the clean water level rises to the overflow pipe and is discharged into the ditch, and will not overflow from the dissolving medicine box; when the liquid level in the storage tank drops to the low liquid level meter, the water inlet solenoid valve, the electric screw conveyor, the vibrator, and the stirrer are started, and a new round of dosing, dissolving, maturing, and dosing processes is started.
