Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, a waste liquid treatment device with automatic pH adjustment includes a waste liquid treatment tank 1, a pH adjustment device 2 is threadedly connected to the waste liquid treatment tank 1, and a control panel 3 is fixedly connected to the pH adjustment device 2;

[0030] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0031] The control panel 3 fixedly connected above the pH adjustment device 2 includes a microprocessor 31, a buzzer 32, a display 33, a switch 34 and an LED light 35. The stirring device 22, the sensor 26, the buzzer 32, the display 33, the switch 34 and the LED light 35 are electrically connected to the microprocessor 31 respectively, and the control panel 3 is electrically connected to an external power supply.

[0032] The sensor 26 includes a water level sensor 261, a pH sensor a262 and a pH sensor b263. The water level sensor 261 is installed on one side of the protective shell 222, the pH sensor a262 is symmetrically installed on the upper end of the other side of the protective shell 222, and the pH sensor b263 is symmetrically installed on the lower end of the other side of the protective shell 222.

[0033] The support base 21 is provided with a receiving groove 27, and the bottom of the reagent bottle 23 is placed on the receiving groove 27 for firmly placing the reagent bottle 23, ensuring that the reagent bottle 23 is fixed when the equipment is running, preventing accidental movement or leakage, and improving the safety of the equipment.

[0034] The reagent bottle 23 includes an acid storage bottle 231 and an alkali storage bottle 232, the connecting passage 24 includes an acid connecting passage 241, an alkali connecting passage 242, an acid injection port 243, and an alkali injection port 244, the water pump 25 includes a water pump a251 and a water pump b251, the acid storage bottle 231 is connected to the top of the water pump a251 through the acid connecting passage 241, and an acid injection port is provided below the water pump a251, the alkali storage bottle 232 is connected to the top of the water pump b252 through the alkali connecting passage 242, and an alkali injection port is provided below the water pump b252.

[0035] The waste liquid treatment tank 1 includes a base 11, a drain pipe 12, a liquid inlet pipe 13 and a tank body 14. The tank body 14 is fixedly connected to the top of the base 11, the drain pipe 12 is fixedly connected to the bottom center of the base 11, and the liquid inlet pipe 13 is fixedly connected to the upper end of the side wall of the tank body 14.

[0036] Working principle: Turn on the power switch 341, so that the control panel 3 and the external power supply are energized, and the water level sensor 261 on the pH adjustment device 2 starts to monitor the water level in the tank body 14 in real time. When the water level in the tank body 14 is lower than 2 / 3, the green indicator light a352 is on and the buzzer is not ringing. When the water level in the tank body 14 is higher than 2 / 3, the water level sensor 261 detects the water level signal and transmits it to the microprocessor 31. The microprocessor 31 controls the red indicator light a351 to light up and the buzzer to sound at the same time to remind the experimenter to deal with it in time to prevent excessive waste liquid from overflowing from the barrel; when the source switch 341 is turned on, the signal of the sensor 26 will be displayed on the display 33 in real time and recorded in real time;

[0037] When the pH adjustment switch 343 is turned on, if the water level is higher than 1 / 2, the water level sensor 261 detects the water level signal and transmits it to the microprocessor 31. The pH sensor a262 and the pH sensor b263 on the pH adjustment device 2 begin to detect and monitor the pH value in the tank body 14 in real time. When the pH value signals of the pH sensor a262 and the pH sensor b263 are stable and tend to be the same, the pH value signal is transmitted to the microprocessor 31. When the pH value is less than 5 or greater than 9, the microprocessor 31 controls the red indicator light b353 to light up and the buzzer 32 to sound. According to the different pH values, the microprocessor 31 calculates the required amount of acid or alkaline reagent and controls the water pump a251 or the water pump b252 to start working, extracting the acid or alkaline reagent from the reagent bottle 23 and injecting it into the tank body 14. At the same time, the microprocessor 31 controls the motor 221 to drive the agitator 223 to start working, thereby automatically adjusting the pH value of the waste liquid in the tank body 14.

[0038] When the pH signals of pH sensor a262 and pH sensor b263 become stable again and tend to be the same, the pH signals are transmitted to the microprocessor 31. When the pH value is between 6-8, the microprocessor 31 controls the green indicator light b354 to light up and the buzzer to turn off. At the same time, the microprocessor 31 controls the motor 221 to turn off to save power. In addition, when the buzzer switch 342 is turned off, the buzzer 32 is powered off to avoid affecting the experimenter during manual maintenance or operation.

[0039] To sum up, the automatic pH adjustment waste liquid treatment equipment of the present invention not only realizes the automatic adjustment and real-time monitoring of the pH value of the waste liquid, but also is easy to operate and maintain in structure, thereby improving the safety and efficiency of the waste liquid treatment process, and is suitable for the waste liquid treatment needs of laboratories and other occasions.
